Applicator and integrated concentrate system

[0001] This application is a continuation-in-part application of co-pending U.S. Pat. No. 10/206,722 filed Jul. 26, 2002 which is a continuation-in-part application of co-pending U.S. Pat. No. 10/124,205 filed Apr. 16, 2002.

FIELD OF THE INVENTION

[0002] The present invention relates to the field of chemical applicators, and more particularly to applicators operating under pressure conditions both ambient and pressurized, for the delivery of plant nutrients and treatments which are commercially available in a more concentrated form than is required at application as a dilute form of the concentrate.

BACKGROUND OF THE INVENTION

[0003] In the botanical maintenance field, workers are called upon to apply a wide variety of chemicals to flora throughout the course of a busy work day. At the worse case, a worker needs to obtain a concentrated supply of a needed chemical or nutrient, measure a given amount of the concentrated nutrient into a container, add makeup diluent, typically water, to a level necessary to make up the final concentration, and then close and put away the concentrated supply container.

[0004] In terms of time, the worker is required to take a significant amount of time in pouring, measuring, or weighing the concentrated chemical, and in retrieving, handling, and restoring the concentrated chemical containers. Further, the process is not only wasteful in terms of time, but it is likely to be messy and produce significant spillage over a period of time. Further, where the concentrate is left at the “fill site”, a number of further problems arise. Any time that concentrate is left at the job site, hose bib, or utility sink, the disadvantages multiply. Functionally it means that the user must return to the site, and that if extra time had not been taken spills contaminate the site. Secondly, leaving chemical at an additional site can lead to liability if third parties come into contact with either the containers or the spills.

[0005] Spillage creates further negative impact from lost concentrate, the waste associated with clean up from paper towels disposed of and rags which become soiled more quickly, and most importantly from the increased contact with the chemical or nutrient in its concentrated form by the worker. Many of the chemicals and nutrients are harmful to workers, especially in their concentrated state. Spillage directly onto the skin of the worker is a particularly dangerous problem, with the degree of danger dependent upon the type and concentration of the chemical in question. Carriage is also a problem. Where a worker has one or two containers of concentrated chemical or nutrient which comprises the main ones of the materials to be used throughout the day, having to separately handle the concentrated material containers in addition to the main applicators, requires additional worker attention, time and trouble. Taking up the attention of the worker when his or her attention should be directed elsewhere enhances the danger potential, especially around plants where a worker could be injured upon impact by the plant.

[0006] What is needed is a system which frees the worker from having to worry about handling and spillage, especially with regard to the concentrated chemicals and nutrients which are used most often. The needed system should include ease of dispensing and re-stocking of the concentrated chemicals to eliminate worker handling and the associated negative impact of spillage. The end result of the needed system is reduced time for measuring, mixing and diluting, and increased worker safety, as well as to promote ease of usage so as to remove the barrier for people to feed their plants regularly. The needed system should also increase the time and ease of mixing and where possible prevent inadvertent spillage of concentrated chemicals and nutrients.

SUMMARY OF THE INVENTION

[0007] The system of the present invention includes the provision of a support of accommodation space on a gravity feed watering device or on a pressurized applicator to both provide storage for concentrated chemical containers, and metered measurement while eliminating waste, make up time and minimizing contact between workers and the chemicals or nutrients in their concentrated state, and to encourage and facilitate the regular feeding of plants, by reducing the trouble and bother associated with feeding plants to increase the regularity with which plants are fed and watered. The aforementioned mechanisms hold true for both commercial workers and home plant enthusiasts, especially hobby growers. Further, the invention makes it less dangerous to bring concentrated material into sensitive areas such as hotel lobbies and restaurants, common atrium areas and similar surroundings where minimum exposure is desired. In terms of commercial workers, the invention should reduce the liability while workers are on the job site by keeping chemicals from children and by reducing or eliminating what would be a further mixing station for the concentrated chemicals.

[0008] In normal usage, concentrated chemical or nutrient containers are stored in a position near the periphery of the entrance of the device, typically a watering device or applicator. From an initial empty state, displacement dispensers atop the concentrated chemical or nutrient containers applicators are activated to meter a pre-determined amount or multiples of such amount of concentrated chemical or nutrient into an opening of the device. Typically water is then added under flowing pressure into the opening to cause the metered chemical or nutrient to become mixed upon the rapid gravity introduction of the water or other mixture forming liquid.

[0009] Structure may be provided to prevent further concentrated chemical or nutrient from being dispensed and may include structure on the general device which blocks metering of the concentrated chemical or nutrient, or blocking members may be placed directly on the concentrated chemical or nutrient containers, or upon structure connected with the main applicator housing which supports the concentrated chemical or nutrient containers. In the alternative, a raised concentrate reservoir may be combined with a catch bib to insure that all chemical is either dispensed directly into the reservoir or collected in the bib for drainage into the main reservoir.

[0010] The manner of integration of the concentrated chemical or nutrient containers into the main applicator can be controlled in accord with shape to achieve important objectives. These objectives may include permitting or encouraging the use of generally compatible chemicals by integrating the container sizes to fit within a provided space. Chemicals which should never be used together can be placed in containers which will not physically fit within the support space, for example.

[0011] Container support and holding spaces may be configured to secure shapes and designs which are in existence or which may be in existence. In some cases, the size of the accommodated containers may be 7.5 inches, 8.5 inches, to 10.5 inches tall. The accommodated containers may be round or cylindrical or triangular or curved edge rectangular. The typical major width dimension may be 3.5 inches, 4 inches 4.5 inches or 5.0 inches. A typical minor width dimension may be 1.5 inches, 2.0 inches to 2.5 inches. The volume of the liquid containers may be from eight ounces to sixteen ounces to almost 40 ounces.

[0012] It is also contemplated that the applicator devices have support spaces which may specifically match with a concentrated chemical or nutrient container and in which the overall capacity of the applicator structure matches with the volume of concentrated chemical or nutrient metering capability of the concentrated chemical or nutrient containers. This opens further the ability to match concentrate containers with applicators. In some cases the accommodation space can be maximized to, in essence, provide an applicator with expanded concentrate containers. This in turn can enhance the use of applicators which are built around a single or even two or three concentrate containers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0037] The description and operation of the invention will be best initiated with reference to FIG. 1 which illustrates a top view of a gravity type applicator <b>11</b>. The gravity type applicator <b>11</b> has a housing <b>13</b> having a central opening <b>15</b>, shown larger than it might normally be provided for emphasis, to show common access by a first container <b>17</b> within a first container accommodation space <b>19</b>. Other structure may be provided for stabilizing the first container <b>17</b> within its container accommodation space <b>19</b>, however where the first container <b>17</b> is largely surrounded and supported, further structure is likely not necessary. First container <b>17</b> is typically filled with a plant nutrient or chemical and may include a pesticide, herbicide, nitrogen food or any concentrated chemical, typically in the liquid state. Container <b>17</b> has, from an upper perspective looking downward, a trapezoidal shape, or somewhat truncated triangular shape, and includes a pump applicator assembly <b>21</b> with a spout extension <b>23</b> which preferably extends over central opening <b>15</b> to allow for ease and secure gravitational deposition of dispensed liquids from container <b>17</b> and into a main reservoir of the gravity type applicator <b>11</b> and in which mixing may occur. An optional “c” shaped locking clip <b>24</b> may be provided to lock the spout extension <b>23</b> in an up position, to prevent further dispensing of the concentrate, and such clip <b>24</b> may be attached loosely to the pump applicator assembly <b>21</b>. The central opening <b>15</b> can be smaller so long as the extension <b>23</b> can gravitationally extend over it enough to reliably deposit a desired amount of concentrated material.

[0038] Further, it is preferable that the pump applicator assembly <b>21</b> have a known or pre-determined metering capability, typically in terms of ab even number of full stroke vertical pump shaft displacements to enable accurate metering of the nutrient or other chemical through the central opening <b>13</b>. This arrangement enables the user to take the guess work out of measurements and to reduce the reservoir replenishment steps to two, namely operating the pump applicator assembly <b>21</b> followed by the introduction of solvent, carrier or other effluent, typically water, into the reservoir connected to the central opening <b>15</b>.

[0039] Note that the first container accommodation space <b>19</b> registers the orientation of the first container <b>17</b> and insures that the first container <b>17</b> must be inserted in a way in which the pump applicator assembly <b>21</b> must be closest to the central opening <b>15</b>. Despite this physical ordering, the spout extension <b>23</b> still needs to be directed over the central opening <b>15</b>. If the spout extension <b>23</b> is ordered with respect to the first container <b>17</b>, either directly as by an upwardly extending boss which permits the spout extension <b>23</b> to be depressed only when the spout extension <b>23</b> is over the central opening; or by registration from the first container <b>17</b>, through the pump applicator assembly <b>21</b> and thence to the spout extension <b>23</b>, it can be seen that a mechanical scheme can be employed to prevent the pump operation when the spout extension <b>23</b> is in a position other than directly over the central opening <b>15</b>. Such a scheme can further help to prevent spillage and also prevent unwanted or inadvertent actuation of the pump mechanisms. In other words, during times when liquid from the first container <b>17</b> is not being metered into the central opening <b>15</b>, the turning of the spout extension <b>23</b> can provide a lockout mechanism.

[0040] Also seen is a second container <b>25</b> within a second container accommodation space <b>27</b>. The shape of both the second container <b>25</b> and the a second container accommodation space <b>27</b> are both round or cylindrical which is likely not to afford registration through the second container accommodation space <b>27</b> and second container <b>25</b>. However, registration may be made through a structure extending from the applicator <b>11</b> housing <b>13</b>, which is not seen in FIG. 1 for clarity of illustration.

[0041] Other structures seen in FIG. 1 include a flow tube <b>31</b> and an angle brace <b>33</b> between flow tube <b>31</b> and the main housing <b>13</b>. At the end of the flow tube <b>31</b>, a strainer or flow disperser <b>35</b> is pivotally mounted adjacent an open end <b>37</b> to enable flow dispersion and also to limit the flow to a convenient rate. Pivotal attachment enables the flow disperser <b>35</b> to be selectively utilized and possibly interchanged with other flow dispersers <b>35</b> having greater and lesser aperture areas. The top view of FIG. 1 omits any handle structure over the top of the applicator <b>11</b> so that the structures can be shown with greater clarity.

[0042] Referring to FIG. 2 , a side view of applicator <b>11</b> illustrates an integral handle <b>41</b> which extends from a rear side <b>43</b> of the gravity type applicator <b>11</b>, upward and over the central opening <b>15</b> and toward a portion of the top of the gravity type applicator <b>11</b> near a front side <b>45</b>. From the view seen in FIG. 2, the view of first container <b>17</b> is most prominently seen. The first container accommodation space <b>19</b> is shown as an opening and pocket which allows the first container to take up or displace space within the reservoir <b>49</b> which may include a water level <b>51</b>. The degree to which the first container accommodation space <b>19</b> “invades” the reservoir <b>49</b> area will depend upon the size and configuration of reservoir <b>49</b> needed and the ability of one or more of the first and second containers <b>17</b> and <b>25</b> to either invade the space of the reservoir <b>49</b> or to become extended outboard of the applicator <b>11</b>.

[0043] Also seen in FIG. 2 is a pocket area <b>53</b> for insertion of an information placard which may include information on one or more of the concentrated chemicals or nutrients within first and second containers <b>17</b> and <b>25</b>, or relating to the use of gravity type applicator <b>11</b> in its expected mode of use. The physical structure of the pocket area <b>53</b> may include an attachable pocket onto a flat surface or a depressed surface within which a label may be attached.

[0044]FIG. 2 also illustrates the action of the flow disperser <b>35</b> and its pivoting connection <b>55</b> onto the flow tube <b>31</b>. As can be seen, the flow disperser <b>35</b> can be pivoted out of the way into a storage position or into place over the open end <b>37</b>. The user controls the position of the flow disperser <b>35</b> at will and the use of flow disperser <b>35</b>, especially depending upon which types of plant application is to be had such as a bulk application at the base or a sprinkling application at top.

[0045] Referring to FIG. 3, a closeup view taken along line <b>3</b> of FIG. 2 illustrates further details and including further details of operation. Flow disperser <b>35</b>, seen from side view, may have a catch <b>57</b> and a pair of spaced apart centering lugs <b>59</b> which may engage the inside edges of the flow tube <b>31</b>. Referring to FIG. 4, a view taken along line <b>4</b>-<b>4</b> of FIG. 3 illustrates a view looking onto the flow disperser <b>35</b> when it is in closed position. As can be seen, the flow disperser <b>35</b> has an array of apertures <b>59</b> to admit and disperse liquid from the flow tube <b>31</b>. Also seen are a pair of holder structures <b>61</b> which are used to engaged the catch <b>57</b> when the flow disperser <b>35</b> is desired to be fixed in an out-of-the-way upper position.

[0046] Referring to FIG. 5, a top view of a pressurizable applicator <b>101</b> typically includes a relatively thick, pressurizable body with a central opening <b>103</b> which may be threaded for facilitating attachment with a pump unit (not shown). A curved opening <b>105</b> may include an upper rail <b>107</b> for supporting several individual concentrated chemical or nutrient containers, such as a first concentrate container <b>111</b> or a second concentrate container <b>113</b>. Each of the first and second concentrate containers <b>111</b> and <b>113</b> includes a pump assembly <b>115</b> having a spout extension <b>117</b>. The ends of the spout extensions extend over the opening <b>103</b> to enable concentrate from the containers <b>111</b> and <b>113</b> to be dispensed directly into the opening <b>103</b> which leads to the reservoir <b>119</b>. The upper portion of the pressurizable applicator <b>101</b> may have a drain off collar <b>121</b> and spout <b>123</b> to assist in transfer of any dilute solution which must be removed at the time of cleaning of the pressurizable applicator <b>101</b>.

[0047] Pressurizable applicator <b>101</b> is preferably fitted with a hose <b>125</b> which is typically in constant communication with the reservoir into which the opening <b>103</b> leads. In many pressurized sprayers, the entire reservoir is pressurized while flow control is effected with a wand mounted at the end of a hose, and the pressurizable applicator <b>101</b> is shown in this type of configuration. A pressure release valve <b>127</b> for venting pressure to enable the pumping unit (not shown) to be removed from the pressurizable applicator <b>101</b> without having to expel the liquid from the reservoir <b>119</b>.

[0048] Referring to FIG. 6, a top view of an integrated pressurizable applicator <b>151</b> typically includes a relatively thick, pressurizable body with a central opening <b>153</b> leading to a reservoir <b>155</b>. The central opening <b>153</b> may be threaded for facilitating attachment with a pump unit (not shown). A curved area <b>157</b> identifies a liquid concentrate reservoir general area which is built into the body of the integrated pressurizable applicator <b>151</b>. A blocking rail <b>161</b> is placed to cooperate with a pump assembly <b>163</b> having a pump depression handle <b>165</b> and extended spout <b>167</b> having a tip end <b>169</b> positioned over the reservoir <b>155</b>. When in an upward position, as when the pump depression handle <b>165</b> is unactuated and in the upper position, the extended spout <b>167</b> is above the level of the blocking rail <b>161</b>. As such, if the extended spout <b>167</b>, which typically can turn 360° as in most pump assemblies including <b>163</b> is directed to any position other than a position where the tip end <b>169</b> is over the reservoir <b>155</b> or a drain off collar <b>171</b> seen adjacent the spout <b>173</b>, the pump assembly <b>163</b> cannot be actuated. Also seen is a short link chain <b>177</b> connected to the blocking rail <b>161</b> and also connected to a funnel <b>179</b>. Where the area <b>157</b> as an area for holding concentrate is integrated with the applicator <b>151</b>, a funnel <b>179</b> will help reduce spillage. Also seen are structures previously seen in FIG. 5, including a hose <b>125</b> and release valve <b>127</b>.

[0049] Referring to FIG. 7, a side view of the integrated pressurizable applicator <b>151</b> is shown with a pumping unit <b>181</b> having a prominent handle <b>183</b>. Typically the handle <b>183</b> can be locked with respect to the pumping unit <b>181</b> to permit the handle <b>183</b> to be utilized to carry the whole integrated pressurizable applicator unit <b>151</b>. It is also seen more clearly that the blocking rail <b>161</b> is an extension of the drain off collar <b>171</b>.

[0050] The area seen as curved area <b>157</b> in FIG. 6 is in fact an internally segregated reservoir area <b>157</b> now seen I FIG. 7. The dashed barrier line <b>185</b> shows the boundary of the internal concentrate reservoir generally represented by the area <b>157</b>. Barrier <b>185</b> provides a physical segregation between an internal segregated area for holding concentrated chemicals or nutrients which are fed through an opening over which the pump assembly <b>163</b> is secured. The shape of the actual area of the concentrate holding volume will depend upon the shape and needs for the internal pressurizable reservoir <b>155</b>. As can be seen in FIG. 7, where the extended spout <b>167</b> is swung to the right and over the blocking rail <b>161</b> that it cannot be depressed. The funnel <b>179</b> is mounted in a manner that it will not be lost and in a position where it can be brought over to an opening which is underneath the pump assembly <b>163</b>, once the pump assembly <b>163</b> is removed to expose the opening into the area <b>157</b> occupied by the concentrate reservoir. Also shown is a pocket area <b>191</b> for placing instructions or labels onto the applicator <b>151</b>. It is understood that the blocking rail <b>161</b> could be provided from the pump assembly <b>163</b> so long as the cap portion of pump assembly <b>163</b> is registerable with respect to the orientation of the central opening <b>153</b>.

[0051] Referring to FIG. 8, a perspective view of an integrated pressurizable applicator <b>201</b> is shown as having an integral reservoir <b>203</b> mounted high upon what would otherwise be a continuation of a shoulder <b>205</b> of the integrated pressurizable applicator <b>201</b>. The high mounting of the integral reservoir <b>203</b> enables a gravity safety system in lieu of the pump lockout mechanism seen in FIG. 7. Rather than disable the operation of a pump unit <b>211</b>, a contoured gravity bib <b>213</b> is seen immediately surrounding a cap <b>215</b>. Regardless of the position of a spout <b>217</b>, any concentrate will flow into a reservoir <b>219</b>. When the spout <b>217</b> is positioned directly over the reservoir <b>219</b>, the concentrate drops directly into the reservoir <b>219</b>. When the spout <b>217</b> is positioned elsewhere, any concentrate will flow onto the contoured gravity bib <b>213</b> and then into the reservoir <b>219</b>. Upon reaching the filling with solute step, solute can be caused to run along the contoured gravity bib <b>213</b> in order to wash it off, but with any excess concentrate going directly into the reservoir <b>219</b>.

[0052] As before, a hose <b>125</b> is seen, and also seen are threads <b>221</b> at the opening <b>223</b> which is again shown with a drain off collar <b>225</b>. Further, the degree of integration of the integral reservoir <b>203</b> to the applicator <b>201</b> main body <b>227</b> will depend upon both convenience and need. In the alternative, the contoured gravity bib <b>213</b> and drain off collar <b>225</b> could be made as a removable unit for attachment about a neck <b>229</b> of applicator <b>201</b> where it is desired to have a quick change complete applicator set.

[0053] Referring to FIG. 10, a left rear perspective view of a second embodiment of a gravity type applicator <b>301</b> includes an integral concentrate container <b>303</b>. The integral concentrate container <b>303</b> has a more gentle curve on the outside surface seen in FIG. 10, and a curved rear and bottom sides which fit into an accommodation space, not completely shown in FIG. 10 because it is occupied by the interfitting integral concentrate container <b>303</b>.

[0054] One aspect of the invention is the ability to provide a wide variety of integral concentrate containers <b>303</b> of different colors especially where any sort of applicator in this application is utilized. This will enable personnel, especially un-skilled worker personnel, to more easily keep up with the proper ones of the integral concentrate containers <b>303</b> to be used. The integral concentrate containers <b>303</b> may preferably be made of clear or light dispersive plastic which transmits enough light to show the liquid level inside. A tag may be used, especially which attaches onto a neck of integral concentrate container <b>303</b> which shows specific information including concentration, warnings, or special instructions, including instructions on dispensing the concentrate.

[0055] Most of the extent of the gravity type applicator <b>301</b>, with the exception of the integral concentrate container <b>303</b> forms a reservoir for being filled with plant nutrient solution typically predominantly including water. The gravity type applicator <b>301</b> is predominantly hollow having a large top opening <b>305</b> leading into an upper reservoir portion <b>307</b> which sits above an expanded base reservoir portion <b>309</b>. The expanded base reservoir portion <b>309</b> provides a wider and longer base which stabilizes the gravity type applicator <b>301</b> to reduce the chances of spilling even when the gravity type applicator <b>301</b> is inadvertently bumped or struck from a position near an upper portion of its structure. A stepped dividing zone <b>311</b> between the upper reservoir portion <b>307</b> and an expanded base reservoir portion <b>309</b> is a slanted shelf which extends from the front to the back of the gravity type applicator <b>301</b>. The shelf nature of the dividing zone <b>311</b> becomes a more steeply defined transition at the mid extent of the applicator <b>301</b>. At the rear extent, the dividing zone <b>311</b> forms its most horizontal shelf extent and meets a heel portion <b>313</b> near the junction of an arched handle <b>315</b>. This area provides a hand hold to facilitate plant feeding while the gravity type applicator <b>301</b> is raised over the user's head, the user typically grasping the rear heel portion <b>313</b> with the user's hand with the user's fingers placed aside either side of the arched handle <b>315</b> at the stepped dividing zone <b>311</b>.

[0056] The base reservoir portion <b>309</b> curves gently upward toward the front of the gravity type applicator <b>301</b> to provide some forward loading when the applicator <b>301</b> is tilted forward. This feature is combined with the arched handle <b>315</b> which extends from the heel portion <b>313</b>, across the top of the large top opening <b>305</b> and forward to the forward most end of the unified dividing zone <b>311</b> which forms the base of a spout portion <b>317</b>. The area immediately below the forward end of the arched handle <b>315</b> is an upwardly tilted portion of the expanded base reservoir portion <b>309</b> underneath the more flattened upwardly disposed forward portion of the dividing zone <b>311</b>. This has the effect of extending the expanded base reservoir portion <b>309</b> forward to both shift the center of gravity forward upon tilting, and also to move the bulk of the liquid away from the large opening <b>305</b> when the applicator <b>301</b> is tilted. This enables the user to worry less about spilling, even when the applicator <b>301</b> is nearly full and tilted significantly.

[0057] The spout-portion <b>317</b> extends to an expansion fitting <b>319</b> and then to a cylindrical portion <b>323</b> which may support optional engagement with a sprinkle screen assembly <b>325</b>. The sprinkle screen assembly <b>325</b> includes a cylindrical body portion <b>327</b> which supports a pair of oppositely oriented hinge fittings <b>329</b>, typically as a pair of oppositely disposed apertures. A pair of oppositely directed hinge projections <b>331</b> are integral with a sprinkle cover <b>333</b> which presents an outwardly curved multi aperture member. This enables the sprinkle cover <b>333</b> to be folded back into “butterfly style” held-open position where a user wants the sprinkle function disabled, and out of the way of a more open flow.

[0058] The arched handle <b>315</b> may preferably be hollow both to provide additional storage capacity especially at the rear of the applicator <b>301</b>, but also at the front of the applicator <b>301</b> adjacent the dividing zone <b>311</b>. The front of the applicator <b>301</b> adjacent the dividing zone <b>311</b> also serves as a source of displacement air so that as the applicator <b>301</b> is righted, all of the balancing air need not come from back as being pulled through the sprinkle cover <b>333</b>.

[0059] Adjacent the large top opening <b>305</b> a vertical feature is seen as a spout guide <b>339</b>. This structure is attached, preferably permanently, about a position adjacent and around a rim <b>341</b> of the large top opening <b>305</b>. It may be riveted with rivets <b>343</b> either to the material of the applicator <b>301</b>, or back onto its own material where provided to hook around the rim <b>341</b>.

[0060] The spout guide shown is designed to allow material to run out a bottom <b>345</b> of a ramp not completely seen in FIG. 10 and over a face <b>347</b> of a fitting <b>349</b> through which extends the rivet <b>343</b>.

[0061] On either side of the ramp, and again the full extent of the ramp is not seen in FIG. 10, are a pair of tall vertical projections <b>351</b> and <b>353</b> which lie to either side of and displaced slightly from a manual pump <b>355</b> having a spout <b>357</b>. A portion of spout <b>357</b> is obscured behind the projection <b>351</b>. The manual pump <b>355</b> is threadably attached to the top of the integral concentrate container <b>303</b>.

[0062] When the integral concentrate container <b>303</b> is placed in its accommodation space (to be more fully shown later), the spout <b>357</b> is simultaneously fitted into a position between the pair of projections <b>351</b> and <b>353</b> as the integral concentrate container <b>303</b> is being fitted into place.

[0063] Once in place, the position of both the integral concentrate container <b>303</b> and the projections <b>351</b> and <b>353</b> are such that the manual pump <b>355</b> spout <b>357</b> is not free to turn either way. The manual pump <b>355</b> may be actuated upwardly and downwardly by having the user press onto the top of the manual pump <b>355</b> in a deliberate manner. However, the manual pump <b>355</b> and spout <b>357</b> are protected from any generalized downward striking motion by the protection afforded by the projections <b>351</b> and <b>353</b>.

[0064] Where the manual pump <b>355</b> and spout <b>357</b> structures are upwardly spring loaded, they will return to their upper position as is seen in FIG. 10. Where no spring loading is present, the manual pump <b>355</b> and spout <b>357</b> may be left in a downward position (not shown in FIG. 10) to provide even more protection against downward actuation. However, since most pump assemblies available commercially are spring loaded to assume an upward, ready-to-pump orientation, the projections <b>351</b> and <b>353</b> will be of especial value in providing coverage against inadvertent actuation when the manual pump <b>355</b> and spout <b>357</b> are in the upward position.

[0065] Further, the projections <b>351</b> and <b>353</b> provide a “locked in” guide which keeps the spout <b>357</b> in line and directly toward the large top opening <b>305</b>.

[0066] Reasonably non-destructive removal of the spout <b>357</b> from between the projections <b>351</b> and <b>353</b> can effectively be accomplished by removal of the integral concentrate container <b>303</b> from the applicator <b>301</b>. Conversely, and as can be seen in FIG. 10, the integral concentrate container can be loaded in a different orientation with the spout <b>357</b> not between the projections <b>351</b> and <b>353</b> so that reasonable care to load the integral concentrate container <b>303</b> into the applicator <b>301</b> should be exercised. The flared entrance to the space between the projections <b>351</b> and <b>353</b> facilitates the guiding of the spout <b>357</b> upon loading of the integral concentrate container <b>303</b> into the applicator <b>301</b>.

[0067] In terms of metering, the use of a guarded system provided by the projections <b>351</b> and <b>353</b> prevents unintended actuation while also facilitating the use of manual pumps <b>355</b> with different metering capability. For a given neck size or metering plunger area, metering limits are typically set by limiting the vertical height over which manual pump <b>355</b> can travel. A small metered flow would be accomplished by providing a manual pump <b>355</b> which might have only a quarter inch stroke from the top of its travel path to the bottom. In this case it would reside only in the lower area between the projections <b>351</b> and <b>353</b>. Since the projections <b>351</b> and <b>353</b> have a flared opening, it is not necessary for a high clearance of the spout <b>357</b> over the projections <b>351</b> and <b>353</b>. Manual pumps similar to manual pumps <b>355</b> of any operating height may be utilized in conjunction with the projections <b>351</b> and <b>353</b>.

[0068] Also seen is a base collar <b>359</b> of the manual pump <b>355</b> which further illustrates the advantages of the two projections <b>351</b> and <b>353</b> as a system which provides significant clearance for a wide variety of fittings or base collars <b>359</b> of a manual pump <b>355</b>. Further, in terms of a stabilizing force, note that arched handle <b>315</b> is not only attached adjacent two dividing zones <b>311</b>, but also by attachment arm <b>361</b> at the more forward end of the applicator <b>301</b> and by attachment arm <b>363</b> at the more rearward end of the applicator <b>301</b>. Both the attachment arms <b>361</b> and <b>363</b> attach the arched handle <b>315</b> to the upper sides of the upper reservoir portion <b>307</b>. Preferably, but not required, is the presence and hollow nature of the arched handle <b>315</b> and its communication with the upper reservoir portion <b>307</b> as well as the expanded base reservoir portion <b>309</b> at its two points of attachment adjacent the dividing zone <b>311</b>. This enables the arched handle <b>315</b> to hold additional water on a level with water in the higher of the upper reservoir portion <b>307</b> and expanded base reservoir portion <b>309</b> when the applicator <b>301</b> is tilted. In essence, expanded water holding capability combines with stability. In addition, displacement air can also readily flow through the arched handle <b>315</b> especially from its connection with the upper reservoir portion <b>307</b>.

[0069] Referring to FIG. 11, a perspective view of the other side of the applicator <b>301</b> illustrates a better view of the face <b>347</b> of the spout guide <b>339</b>. Now, above the bottom <b>345</b>, a curved ramp <b>371</b> can be seen. The geometry seen in FIG. 11, combined with that of FIG. 10 helps to complete an understanding of the flow of concentrate after it leaves the end of the spout <b>357</b>. The concentrate drops onto the ramp <b>371</b> to flow over the face <b>347</b>, and through the large top opening <b>305</b> into the upper reservoir portion <b>307</b>. The general configuration of the fitting <b>349</b> illustrates a construction that is self contained, and prevents any dispensed concentrate from entering any space between the fitting <b>349</b> and an upper surface <b>373</b> of the upper reservoir portion <b>307</b>. Further, the ramp <b>371</b> will be continually washed with fresh amounts of concentrate, of any type, and should generally operate to keep itself clean. Clearing water can also be introduced down the ramp <b>371</b> on each subsequent filling of the applicator <b>303</b> to keep it clean.

[0070] Notice also that gross volume measurement level marks are present, including a volume mark <b>375</b> to indicate a two gallon level and a volume mark <b>377</b> to indicate a one gallon level. Further volume marks can be supplied both on the upper reservoir portion <b>307</b> and farther down on the expanded base reservoir portion <b>309</b> where necessary. However, given the precision metering ability of the manual pump <b>355</b> and the more precise level measurement of concentrate from the concentrate container <b>303</b>, the user will be able to control the concentrations accurately without having smaller denomination measurements on the applicator <b>303</b> housing.

[0071] Referring to FIG. 12, an expanded view of the integral concentrate container <b>303</b> being removed from the gravity type applicator <b>301</b> illustrates further details thereof. The integral concentrate container <b>303</b> is seen as having a front face <b>381</b> separate from the outer surface of the upper reservoir portion <b>307</b>. An upper surface <b>383</b> reveals that the integral concentrate container <b>303</b> has a “D” shaped cross section which includes a curved surface <b>385</b> which extends in a continuous curve from a left to rear to right side smoothly.

[0072] This curved rear portion of its cross sectional shape allows the integral concentrate container <b>303</b> to fit into a compartment <b>391</b> which includes a floor surface <b>393</b>, a curved transition surface <b>395</b> and leading to a generally vertical, curved rear surface <b>397</b>. At the top of the compartment <b>391</b> a portion <b>399</b> of the upper surface <b>373</b> comes forward in a thin “U” shape to engage a mating surface located just below the base collar <b>359</b>.

[0073] A series of relationships can be used to keep the integral concentrate container <b>303</b> securely carried within the compartment <b>391</b>. These can include for example making floor surface <b>393</b> slightly lower than an edge <b>401</b>, or adjusting the portion <b>399</b> so that it works in conjunction with the floor surface <b>393</b> to “trap” the container <b>303</b>, such as by being able to be deflected upwardly.

[0074] Another mechanism is also shown in FIG. 12. A member <b>405</b> is seen on the integral concentrate container <b>303</b> which may be either a projection or a depression. Member <b>405</b> is positioned to complementarily contact a member <b>407</b> on the inside of the generally vertical, curved rear surface <b>397</b>. Member <b>407</b> is the other of a projection or depression and enables a hold in fit with the member <b>405</b>. The fit relationship can be snap, interference, latch, spring powered and the like or have a further relationship.

[0075] Also seen is the extension of the curved edge <b>401</b> along an extent adjacent both the floor <b>393</b> and upward along both sides adjacent to the generally vertical, curved rear surface <b>397</b>. The curvature of the edge can be severe or gentle to facilitate handling by increasing or decreasing the ease with which the human hand can grasp the integral concentrate container <b>303</b>. The “D” shaped curved surface <b>385</b> has a tighter radius of curvature at its rearmost extent to facilitate the rapid, easy loading of the integral concentrate container <b>303</b> into the compartment <b>391</b>. The integral concentrate container <b>303</b> can be, depending upon the details of orientation, loaded by angling the bottom in first or by first positioning the base collar <b>359</b> with respect to the portion <b>399</b> followed by pushing the bottom of the integral concentrate container <b>303</b> into place. In some configurations integral concentrate container <b>303</b> may be loaded in with a vertical orientation. Removal of the integral concentrate container <b>303</b> can be accomplished by grasping and pulling outwardly on the base collar <b>359</b>.

[0076] Front face <b>381</b> of the integral concentrate container <b>303</b> is shown as being marked with volumetric indicator marks <b>411</b>. Near the bottom of the integral concentrate container <b>303</b>, the front face <b>381</b> has an outward curvature <b>413</b> followed by a downward curvature <b>415</b> leading to a forwardly displaced vertical portion <b>417</b>. However, the integral concentrate container <b>303</b> need not have the exact shape details seen in FIG. 12. Integral concentrate container <b>303</b> can also have manual assists for instances where it needs to be changed more quickly or more often.

[0077] Referring to FIG. 13, a side view of the integral concentrate container <b>303</b> is seen, without the manual pump <b>355</b> and with the base collar <b>359</b> removed to expose an upper neck <b>421</b> having a simple thread <b>423</b>.

[0078] Referring to FIG. 14, a top view of the integral concentrate container <b>303</b> again shows the upper neck <b>421</b> as having an opening <b>425</b>. The curved surface <b>385</b> is shown as having about 180° of curvature having an even radius about the upper neck <b>421</b>. The 180° of curvature levels into a flat portion <b>427</b> and a flat portion <b>429</b> identifiably seen for the first time in FIG. 14.

[0079] Referring to FIG. 15, a further embodiment of a pressurized applicator is seen as integrated pressurizable applicator <b>501</b>. Applicator <b>501</b> has a body <b>503</b> having an integral internal reservoir (not shown in FIG. 15) and a concentrate container system <b>505</b> which includes a concentrate container <b>507</b>, neck unit <b>509</b> and a pump unit <b>511</b> of which can be seen a collar <b>513</b>, pump head <b>515</b> and spout <b>517</b>.

[0080] Above the collar <b>513</b> and also mounted above the body <b>503</b> is a potentially removable drainage basin <b>521</b>. Drainage basin <b>521</b> can be seen to act to prevent any downward motion on the pump head <b>515</b> by virtue of interference of the spout <b>517</b> with the drainage basin <b>521</b>. Only when the spout <b>517</b> is directed over the entrance, which is occupied by a pressurizing unit <b>523</b> in FIG. 15, will the pump head <b>515</b> have the ability to be depressed freely. Even where the spout <b>517</b> is not directly over the opening into the integral internal reservoir (not shown in FIG. 15), any dispensed concentrate will drain into such opening, assisted by the drainage basin <b>521</b>. An upper edge <b>525</b> of the drainage basin <b>521</b> radially and blockingly “tracks” the spout <b>517</b> throughout the portion of its radial pivot ability when it is not nearest the area within the drainage basin <b>521</b> which is shown in FIG. 15 to be occupied with the pressurizing unit <b>523</b>.

[0081] The radial distance of the upper edge <b>525</b> is seen to engage the spout <b>515</b> between its plunger <b>527</b> and spout tip <b>529</b>. It is to be emphasized that upper edge <b>525</b> may have a radially expanded distance to simply catch any drips from the spout <b>517</b> to direct those drips to the center opening (not shown in FIG. 15), or the spout <b>517</b> may have a reduced radial distance. In this case, the height of the upper edge <b>525</b> may be increased to block generally all but deliberate access to the pump head <b>515</b>. In an alternative configuration the height of the pump head <b>515</b> may be lowered, relative to the upper edge <b>525</b>, to further prevent inadvertent dispensing of concentrate. The rim <b>525</b> of the drainage basin <b>521</b> has an expanded radius portion surrounding the pressurizing unit <b>523</b> of which the pump handle <b>523</b> is visible in FIG. 15.

[0082] Also seen extending to one side of the body <b>503</b> is a hose connection <b>531</b>. Drainage basin <b>521</b> is also seen as having a lower collar <b>533</b> which may form a partial or total support for the drainage basin <b>521</b>. A safety relief valve <b>535</b> is also seen on the body <b>503</b>.

[0083] Concentrate bottle <b>507</b> is shown as being supported by a shelf extension <b>541</b> extending from a lower portion of the body <b>503</b>. Structures to be shown will illustrate some possible structure to assist holding concentrate bottle <b>507</b> in place. Also seen is an indented area <b>543</b> which defines the body <b>503</b> legs or stability projections.

[0084] Referring to FIG. 16, a partially exploded view of the integrated pressurizable applicator <b>501</b> is shown with the concentrate container system <b>505</b> in a removed and exploded position. The concentrate container <b>507</b> is seen as a generally cylindrical container having an upper opening <b>555</b> surrounded by threads <b>557</b> on a circumferentially indented land <b>559</b>. From the land <b>559</b> the sides of the concentrate container <b>507</b> is generally linearly cylindrical, terminating in a curved transition <b>561</b> to a flat bottom <b>563</b>. A rim <b>565</b> exists at the top of the land <b>559</b> which is preferably enabled to accept a sealing member (not shown) and which is to be further illustrated with respect to a concentrate system.

[0085] A sealing member will preferably be of the type which adheres to an upper rim and which can be either punctured or peeled away. As will be shown, the integrated pressurizable applicator <b>501</b> utilizes a concentrate container system <b>505</b> which minimizes human contact with the concentrate and minimizes spillage. In the configuration shown, the puncturing of any covering seal will occur at its center due to the generally concentric nature of the concentrate container system <b>505</b>.

[0086] The neck unit <b>509</b> has a set of internal threads adjacent its underside for engagement with threads <b>557</b> of the concentrate container <b>507</b>. Neck unit <b>509</b> extends upwardly to a land <b>569</b> having threads <b>571</b>. Land <b>569</b> has an opening <b>573</b> at its upper end. The neck unit <b>509</b> acts as an adapter to the concentrate container <b>507</b>, and can differ as needed to accommodate different configurations of pump sets having different connection fittings. In the alternative a single solid container can be utilized.

[0087] To the right of the neck unit <b>509</b> and concentrate unit <b>507</b> is a pump set <b>575</b> which includes a boss <b>577</b> above the collar <b>513</b>, and a main housing <b>579</b> below the collar <b>513</b>. Below the main housing <b>579</b> is a pickup tube <b>581</b> having a lower end <b>583</b> which is cut at an angle to form a sharp tip. Also seen is the fact that the plunger <b>527</b> extends down into the boss <b>577</b>.

[0088] The concentrate container <b>507</b> is seen to fit into a curved space <b>585</b> formed by a portion of the outside of the body <b>503</b>. Space <b>585</b> has a projection <b>587</b> which engages an indentation (not shown) on the concentrate container <b>507</b>. The curved space <b>585</b> leads down to a shelf <b>589</b> which supports both the concentrate container <b>507</b> and an upward button protrusion <b>591</b>, which similarly fits into a small indentation (not shown) on the concentrate container <b>507</b>. Each of the members including projection <b>587</b> and upward button protrusion <b>591</b> limit the movement of the concentrate container <b>507</b> out of the curved space <b>585</b> by providing a general orthogonal entry into the body of the concentrate container <b>507</b>.

[0089] Changing of the concentrate container <b>507</b> is had by bringing the bottom outward and over the relatively low height upwardly projecting button protrusion <b>591</b>. The more upwardly located connection with the projection <b>587</b> enables a reduced removal angle. Removal can be completed by either having the pump set <b>575</b> lowered and angled out so that the spout <b>517</b> can clear an opening (not yet shown) in the drainage basin <b>521</b>. In the alternative, the collar can be threadably removed from the threads <b>571</b> by turning the boss <b>577</b> from within the drainage basin <b>521</b> to remove the pump set <b>575</b>. After removal of the pump set <b>575</b>, the empty concentrate container <b>501</b> with its attached neck unit <b>509</b> can be can be removed by either urging the bottom or the top of the concentrate container <b>507</b> laterally away from the body <b>503</b>.

[0090] Referring to FIG. 17, a sectional view of the integrated pressurizable applicator <b>501</b> is seen. The details of the pressurizing unit <b>523</b> are not shown beyond the partial and slight detail of the handle shape. Typically this pressurizing unit <b>523</b> threadably disengages internally from a neck <b>597</b> of the body <b>503</b> by turning the handle seen at the top of pressurizing unit <b>523</b> from either a locked position or a position of maximum angular displacement in one direction. In the unlocked (or unthreaded in the case of a threaded hold down) position, a handle is usually free to be raised and lowered to introduce pressure into a reservoir <b>599</b>.

[0091] As can be seen, the neck <b>597</b> forms an anchor to which the lower collar <b>533</b> is attached. Attachment may be by close fit, pin lock, gluing or any other acceptable method. In some of these methods, the drainage basin <b>521</b> may be removable. In the configuration shown, the locking down of the pressurizing unit <b>523</b> also causes the drainage basin <b>521</b> to be locked down and otherwise supported.

[0092] To the right of the lower collar <b>533</b>, the drainage basin <b>521</b> can be seen to have an opening <b>601</b> through which the boss <b>577</b> of the pump set <b>575</b> is seen to immediately extend. Depending upon the size of the pump head <b>515</b>, it is possible to angle the concentrate container <b>507</b> away from the body <b>503</b> with the drainage basin <b>521</b> still in place, and allow the plunger <b>527</b> to pass downwardly through the opening <b>591</b> without having to disconnect the pump set <b>575</b> from the concentrate container <b>507</b>. The ability and desirability to do this may depend not only on the overall size of the pump head <b>515</b>, but also the height and diameter of the material surrounding the opening <b>601</b>. Further, the material surrounding the opening <b>601</b> can be adjusted to engage the boss <b>577</b> or even the top of the collar <b>513</b> to provide further support to the drainage basin <b>521</b>.

[0093] As can be further seen, the concentrate container <b>507</b> is held in place by the projection <b>587</b> extending into an indentation <b>605</b>. Similarly, upward button protrusion <b>591</b> is seen protruding into an indentation <b>607</b> located at the bottom center of the concentrate container <b>507</b> and located at the center of generally flat bottom <b>563</b>.

[0094] Referring to FIG. 17, a more complete exploded view of the concentrate container system <b>505</b> illustrates some of the flexibility involved with the use of a wide mouth concentrate container <b>507</b> along with a neck unit <b>509</b>. As can be seen, the wide mouth concentrate container <b>507</b> may be supplied with a sealing plastic or foil or other thin planar sealing member <b>621</b> which engages the upper rim <b>565</b> of the circumferentially indented land <b>559</b>. Above the foil member <b>621</b>, and as an option, a reinforcement ring <b>623</b> having a smaller central aperture <b>625</b> is seen. The reinforcement ring <b>623</b> is especially useful for concentrating any puncturing forces from the pickup tube <b>583</b>. Concentration of puncture forces will prevent lateral wide tearing of the foil member <b>621</b>, and will prevent stretching of the surrounding areas of the foil member <b>621</b>. This can be particularly important if some sealing is desired around the pickup tube <b>583</b>. The reinforcement ring <b>623</b> smaller central aperture <b>625</b> gives the ability to (1) concentrate puncture area, (2) concentrate puncture forces, (3) limit tearing to a small area, and (4) provide some sealing about the pickup tube <b>583</b>. The reinforcement ring <b>623</b> can be made of flexible material to further accomplish this task.

[0095] Above the neck unit <b>509</b>, a smaller diameter sealing plastic or foil or other thin planar sealing member <b>631</b> is seen. Where a small area of material is provided, and depending upon the selection of material, a similarly small reinforcement ring <b>623</b> can be eliminated. The user can be supplied with a bottle having the dimensions of the combined concentrate container <b>507</b> and neck unit <b>509</b> or the user can be supplied with a simple concentrate container <b>507</b>, especially sealed with a foil member <b>621</b> and optional reinforcement member.

[0096] It is believed that where a liquid bottle is supplied, a single bottle with a small opening <b>573</b> would be desirable. Where a powder or dehydrated mixture is supplied, the concentrate container <b>507</b> may be supplied alone. This may include the case where water or other fluid is added to an un-dissolved powder. In both cases the system provides maximum flexibility to users, manufacturers, and concentrate suppliers.

[0097] Referring to FIG. 19, a further embodiment is seen as a gravity type applicator <b>651</b> which has features which are more centered and vertically oriented. A concentrate container <b>653</b> is seen a separated from the gravity type applicator <b>651</b>. Concentrate container <b>653</b> is vertically taller and thus has a little additional volume capability for a given set of other dimensions.

[0098] The floor surface <b>393</b> and generally vertical, curved rear surface <b>397</b> seen in gravity type applicator <b>301</b> is replaced by a pure vertical axis horizontal indentation <b>655</b> which may have no floor surface. A single projection <b>657</b> is seen extending from a point generally near the middle of the horizontal indentation <b>655</b> and matches bore <b>659</b> shown in phantom at the rear of the concentrate container <b>653</b>. Aside from support had just below the base collar <b>359</b>, the bore <b>659</b> connection with the projection <b>657</b> provides the only other support for the concentrate container <b>653</b>. Note also that the concentrate container <b>653</b> has been located more rearwardly than the position of concentrate container <b>303</b> with respect to gravity type applicator <b>301</b>. This offers different advantages of enabling user contact directly with the bottom of the concentrate container <b>653</b>, as well as a more centered center of gravity profile.

[0099] Projection <b>657</b> is seen as being cylindrical, but need not be. Projection <b>657</b>, as well as bore <b>659</b>, can be angled upwardly to obtain a better hold on the concentrate container <b>653</b>. Further, the projection <b>657</b>/bore <b>659</b> holding system can be supplemented by other holding structure possibly in conjunction with other structures.

[0100] In addition, a matching one piece holding and flow directing structure <b>661</b> is provided which includes a curved portion <b>663</b> and an enclosed guide structure <b>665</b> having a side opening <b>667</b>. The enclosed guide structure <b>665</b> has a bottom opening (not shown) preferably with a sleeved extension extending through a matching opening in a top surface <b>671</b> upon which the guide structure <b>665</b> is mounted. This enables dispensed concentrate to fall directly into the inside of the upper reservoir portion <b>307</b> to further eliminate surfaces, especially surfaces which are slightly horizontal which might come into contact with, and delay the entry of concentrate. The entry of the spout <b>357</b> into the opening <b>667</b> is by a slight turning motion, similar to that seen in gravity type applicator <b>301</b>. The flow directing structure <b>661</b> provides a more protected structure to both guard against inadvertent actuation as well as some added degree of isolation of the concentrate. Rivets <b>675</b> are seen holding the flow directing structure <b>661</b> atop the top surface <b>671</b>.

[0101] A more compact sprinkle screen assembly <b>681</b> is seen having a housing <b>683</b>. Referring to FIG. 20, a view of the detached compact sprinkle screen assembly <b>681</b> is seen having a cover <b>685</b> having side pinned projections <b>687</b>. The cover <b>685</b> has a series of holes <b>689</b> to enable a sprinkles flow when the cover <b>685</b> is rotated to a covering position within the housing <b>683</b>. The wall thickness of the cylindrical portion <b>323</b> should ideally be thin enough to insure that the cover <b>685</b> swings freely open. Detent notches both forwardly and rearwardly adjacent the housing <b>683</b> near the pinned projections <b>687</b>, will enable the cover <b>685</b> to be held in the open position.

[0102] Referring to FIG. 21, a side perspective view of a gravity type applicator <b>701</b> has a few additional features of note. At the left, a gravity type applicator <b>701</b> is seen to have a recessed sprinkle screen assembly <b>703</b> to provide additional protection for the sprinkle cover <b>685</b>. A matching one piece holding and flow directing structure <b>705</b> includes a neck reinforcement partially surrounding boss <b>707</b> to provide a more strengthened lock between the base collar <b>359</b> and top of a concentrate container <b>711</b>. The terminations of the boss <b>707</b> are wedge shaped which enable the gap between the base collar <b>359</b> and top of a concentrate container <b>711</b> to be used to mount it on the wedge shaped boss <b>707</b> to get a good lock on the holding of the concentrate container <b>711</b>.

[0103] The concentrate container <b>711</b> includes a pair of wedge shaped projections <b>713</b> near its base, one of which is seen in FIG. 1. The wedge shaped projections <b>713</b> slip past a matching pair of interference structure projections (not shown in FIG. 21)on the inside of the vertical axis horizontal indentation <b>655</b>. The wedge shape of the projections <b>713</b> assist in ease of locking and in maintaining the concentrate container <b>711</b> into place. As before, the spout <b>357</b> of the manual pump <b>355</b> is guided into the side opening <b>667</b> as the concentrate container <b>711</b> is loaded onto the matching one piece holding and flow directing structure <b>705</b>. Also note that as a variation, a set of volumetric indicator marks <b>717</b> are located on the side of the concentrate container <b>711</b>.

[0104] Referring to FIG. 22, a further variation on the matching one piece holding and flow directing structure <b>705</b> is shown. A unitary combination matching one piece holding, rim and flow directing structure <b>721</b> is shown in exploded view over the gravity type applicator <b>701</b> seen in FIG. 21. The combination matching one piece holding, rim and flow directing structure <b>721</b> may be particularly advantageous for cases where the large top opening <b>305</b> is not as finished as would be desired or where the top opening <b>305</b> needs to be utilized for additional stability.

[0105] The unitary combination matching one piece holding, rim and flow directing structure <b>721</b> has a downwardly directed flange <b>723</b> which fits into the opening <b>305</b> which helps to stabilize and register the unitary combination matching one piece holding, rim and flow directing structure <b>721</b>. A pair of apertures, including the aperture <b>725</b> which is seen on the unitary combination matching one piece holding, rim and flow directing structure <b>721</b> are used to hold it in place. With the additional stabilization of the flange <b>723</b>, a lesser number of apertures may be necessary. A pair of apertures <b>727</b> are seen on the upper surface <b>671</b> of the gravity type applicator <b>701</b> which align wit the apertures <b>725</b>.

[0106] In FIG. 22, one of two vertical projections <b>731</b> are seen just inside the lower extent of the vertical axis horizontal indentation <b>655</b>.

[0107] Referring to FIG. 23, a sectional view taken along lines <b>23</b>-<b>23</b> of FIG. 21 shows a recessed sprinkle screen assembly <b>703</b> which is oriented to open by pivoting in one direction only. A cover <b>741</b> has water flow apertures <b>743</b> and is mounted to pivot adjacent an interference projection <b>745</b>. On one side of the pivot of the cover <b>741</b>, an inside portion of the recessed sprinkle screen assembly <b>703</b> is provided as a sweeping surface <b>751</b>, so that the cover <b>741</b> will sweep toward the main body of the gravity type applicator <b>701</b>. At the other side of the pivot of the cover <b>741</b>, an inside portion of the recessed sprinkle screen assembly <b>703</b> includes a stop lip <b>753</b> which prevents motion of an abutting portion of the cover <b>741</b> from movement in the direction of the gravity type applicator <b>701</b>.

[0108] By providing movement in one direction only, a closer tolerance can be provided to enable the cover <b>741</b> to become more easily fixable in the open position. The interference projection <b>745</b> is used to keep the cover <b>741</b> in the open position. It is preferable to mark the cover <b>741</b> to indicate the direction of movement by pressing the side of the cover <b>741</b> nearest the sweeping surface <b>751</b>. Further, an extended forward portion of the housing of the recessed sprinkle screen assembly <b>703</b> provides additional protection for the cover <b>741</b> when it is in the open position.

[0109] Further, the flexibility for sealing will provide manufacturers and users with new options for recycling. By standardizing the containers in a way which maximizes their usage, recycling is facilitated. Recycling includes cleaning, re-filling with more concentrate and re-selling. The concentrate container system <b>505</b> also facilitates the use of colors to identify different types of concentrate.

[0110] While the present invention has been described in terms of a system for providing convenient metered concentrate with respect to a dilute dispenser system, the principles contained therein are applicable to other types of systems.

[0111] Although the invention is derived with reference to particular illustrative embodiments, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. Therefore, included within the patent warranted hereon are all such changes and modifications as may reasonably and properly be included within the scope of this contribution to the art.
