Background of the Invention

Background Field

The present invention generally relates to a passive volatile material dispenser.

Background Description

It is known that various volatile material dispensing devices generally include a reservoir containing a volatile material and may include a housing or support structure for retaining the reservoir. These devices typically either allow passive diffusion of volatile material to be carried out without the aid of a dispensing mechanism or that enhance and / or facilitate the release of volatile material using a dispensing mechanism. Dispensing mechanisms typically used in volatile material dispensing devices include a heating device and / or a fan. Such prior passive dispensers commonly require expensive materials that lead to more expensive dispensers. In sum, common volatile materials incorporated in gel and wax systems tend to be fragile. Such volatile materials are, therefore, susceptible to impact, extreme temperatures and humidity changes. Therefore, there is a need to develop durable and inexpensive passive dispensers that provide greater accessibility to volatile dispensers in harsh environments.

Summary of the Invention

According to one aspect, a dispenser for dispensing an insect control asset includes a porous substrate impregnated with an insect control asset. The porous substrate has a minimum bending moment of about 150 to about 275 g-cm. Upon activation, the dispenser exhibits an effective release rate of the insect control active from about 0.1 to about 0.3 mg / hr.

According to another aspect, a method of using a passive volatile material dispenser includes identifying a limited space to be protected from a pest. The limited space includes a horizontally placed upper barrier, a vertically placed perimeter barrier that extends from the upper barrier to a lower barrier, a first zone that extends vertically downward from the upper barrier at a first height, and a second zone that It extends down vertically from the first height towards the lower barrier. The method also includes the steps of activating a passive volatile material dispenser that includes a porous substrate impregnated with an insect control asset, and placing the activated passive volatile material dispenser in the first zone. Each of the upper and perimeter barriers is at least partially impermeable to air currents.

According to an additional aspect, a method of providing a passive volatile material dispenser to consumers includes providing a sealed bag containing a passive volatile material dispenser having instructions. The passive volatile material dispenser includes a porous substrate impregnated with an insect control asset. The instructions direct a consumer to open the bag and remove the passive volatile material dispenser therefrom to activate said passive volatile material dispenser, and to place the passive volatile material dispenser substantially in the center of a room.

Detailed description of the invention

As depicted in FIGS. 1 to 11, a dispensing device 10 generally includes a substrate 12 and a volatile material 14 placed on and / or in the substrate. The dispensing device 10 is adapted to passively dispense volatile material 14 when air flows through and / or around the substrate 12.

The substrate 12 includes a first portion of the wall 16 and a second portion of the wall 18 joined by a hinge to a first portion of the wall along a fold line 20. The substrate 12 may also include one or more openings 22 in any way to allow the dispenser 10 to hang, for example, from a display to hang on the wall or other location when in use and / or to increase the flow of air through the dispenser. Additionally, a strap (not shown) can be provided through the opening 22 to help hang the dispenser 10.

The substrate 12 is designed to carry volatile material 14, either on a surface thereof and / or being absorbed by it, and release it into the environment once it is exposed to it. In one embodiment, the substrate 12 includes a volatile asset permeable material, such as a substrate containing cellulose fiber. Cellulose fiber based substrates may include an amount of cellulose by weight ranging from less than about 50% to about 99%, or about 75% to about 99%, or about 95% to about 99%, or about 97.5% to about 98.5%, or so. Similarly, cellulose fiber based substrates may include an amount of a secondary material in a weight ranging from about 1% to more than about 50%, about 1% to about 25%, or about 1% to about 5 %, or about 1.5% to about 2.5%, or so. Secondary materials include, for example, binders, pigments, polymers, resins, dyes and other materials known in the art. In one embodiment, a substrate based on cellulose fiber may have approximately 98.5% cellulose and approximately 1.5% hydrorsistant polyamide resin.

In one embodiment, cellulosic materials, such as those available from EMI Specialty Papers (Redding, Connecticut) can be used. Specifically, a particular modality uses EMI Specialty Papers Grade 30250 cardboard. Another modality uses Grade 18430 from EMI Specialty Papers. Additional substrate materials contemplated include crepe paper, printing paper, A4 paper and other cellulosic materials. Additional examples of the materials contemplated for substrate 12 include plastics, polymers, fabrics, nonwoven substrates, such as a PET nonwoven substrate and / or combinations thereof. Additionally, the substrate 12 may include combinations of manufactured, natural and recycled or recovered materials. Furthermore, it is contemplated that the substrate 12 may include a laminate composed of two or more layers of materials, wherein the laminate may include only materials permeable to volatile assets or combinations of materials impermeable and permeable to volatile assets.

In one embodiment, the substrate 12 has a smooth, flat appearance. In another embodiment, however, the substrate 12 may have various textures and / or surface patterns, such as a rough surface, a smooth surface, a corrugated surface and combinations thereof that can increase the surface area and / or the emanation speed of the composition. The substrate 12 can be of any size or shape. For example, the substrate 12 may have a rectangular configuration and dimensions of approximately 2.5 cm to approximately 25 centimeters, or approximately 5 centimeters to approximately 12 centimeters, or approximately 7.5 centimeters to approximately 13 centimeters, and the like. Additional shapes contemplated include circles, hearts, diamonds, squares, triangles or any other geometric shape.

An additional criterion that may be relevant for choosing a substrate 12 includes the thickness and gauge of the substrate. For example, the substrate 12 may have a thickness (± 10%) of about 0.15 mm, or about 0.3 mm, or about 0.4 mm, or about 0.5 mm, or about 1 mm, or about 2 mm, or about 3 mm, or about 5 mm, or about 10 mm. In addition, the basic weight of cellulosic materials may be of interest when such substrates are chosen. For example, a basis weight (± 10%) of about 250 gsm, or about 300 gsm, or about 330 gsm may be desirable. In addition, the speed of a cellulosic substrate can be considered. For example, a speed ((± 10%) of about 50 ml / minute, or about 60 ml / minute, or about 70 ml / minute, or about 100 ml / minute is desirable. Another factor to be considered for cellulosic substrates includes wet burst strength. For example, a desirable substrate may have a wet burst (± 10%) of approximately 180 centimeters H₂O, or about 215 centimeters H₂Or, or about 250 centimeters H₂O, or about 280 centimeters H₂OR.

The stiffness or hardness of a substrate may be an additional criterion to be considered when choosing a substrate. Proper rigidity can help in the appearance and stability of the substrate by reducing the amount of substrate ripple when impregnated with a composition and / or when exposed to moisture conditions. A measure of the hardness is the Taber hardness or the moment of flexion (represented in g-cm or mN * m). For cellulosic substrates, these measurements can be taken along the direction of the machine direction (MD) and cross machine direction (CD) orientations of the cellulosic fibers of the substrate. For example, the minimum bending moments for a desirable substrate may be in a range (± 10%) of 5 to about 10, or about 10 to about 25, or about 20 to about 100, or about 50 to about 175, or approximately 100 to approximately 225, or approximately 150 to approximately 275, or approximately 200 to approximately 325 g-cm or more as measured by a Taber type tester in a basic configuration (TAPPI standard T

489 om-13) or a Taber type tester in a configuration from 0 to 10 (TAPPI standard T 566 om-08), where the tester was verified with a standard control paper.

In addition, another measure is the flexural strength (represented in mN) of a substrate. Such a measure is important in the present context where a dispenser 10 can be used in different states according to whether the dispenser is in a two-dimensional state or a three-dimensional state after being manipulated by the user. For example, a substrate may require a minimum average force to overcome the flexural strength inherent in the substrate. In one embodiment, a substrate may require (± 10%) at least about 30 mN, or

overcome its flexural strength.

For example, a comparison of the substrate hardness and its flexural strength for a couple of different substrate materials (EMI 18430 and A4 (80 gsm)) is shown in Table No. 1 taken according to the test methodologies previous.

Another factor that can be considered when choosing the substrate 12 is the release rate of a composition impregnated with the substrate. For example, a substrate 12 may be chosen to provide a release rate so that an effective amount of a volatile material, such as an insect control asset, which can be an insecticide or an insect repellent, is released by a specific period of time, such as for about 1, or about 2, or about 4, or about 7, or about 14 days. In one embodiment, the insect control asset may be a mosquito control asset, such as an insecticide or repellent effective against mosquitoes. In addition, the substrate 12 can also be chosen based on its ability to maximize the release of a composition contained therein, so that at the end of the life of the dispenser 10, a minimum amount of the composition is still contained therein. . An example of the amount of the composition released over a period of time is shown below in Table No. 2, which illustrates the remaining insecticide (TFT = transflutrin) in milligrams at different particular times for a period of 14 days. Each substrate starts with 80 mg TFT.

<td>EMI30250</td><td> 78.4</td><td></td><td> 62.5</td><td> 49.1</td><td> 23.2</td>

Table No. 3 illustrates the average release rates (mg / hr) of the three substrates shown in Table No. 2 based on the amount released on day 7.

<td>EMI 18430</td><td> 0.3</td>

<td>EMI 30250</td><td> 0.1</td>

Based on the data in Tables Nos. 2 and 3, EMI 18430 can be chosen as a more effective substrate due to the higher release rate, which translates into a reduced remaining amount of the composition on the card and greater efficiency . The contemplated effective release rates of the insect control asset in a substrate can be about 0.05 mg / hr, or about 0.1 mg / hr, or about 0.2 mg / hr, or about 0.3 mg / hr, or about 0.5 mg / hr

Dispenser 10 will acquire a portion of volatile material 14 therein and / or from it and dispense it from the dispenser. Suitable volatile materials / assets may include, for example, insect repellents or insecticides. Alternatively, any other volatile material known to those skilled in the art can be used.

In one embodiment, the insect control asset may include D-teflumethrin, transflutrin, prallethrin, vaportrin, metoflutrin, teflutrin, sbiotrin, other synthetic pyrethroids, and combinations thereof. In another embodiment, the insect control asset may include insect repellents, such as, for example, mosquito repellents. The composition may only include an insect control asset or may also include a water-based and / or oil-based carrier, a hydrocarbon, an alcohol, for example, ethanol or other solvent or carrier, and combinations thereof. . It is contemplated that fragrances may be used as "depletion" indicators, so that when a user cannot continue to perceive the essence of the fragrance, the strength of the insect control asset will have no more effect for the purpose it is intended to have and will It requires a new device or the device must be “recharged” with another dose of the composition or replaced. In this modality, the emanation rate of the fragrance and that of any volatile asset are substantially the same. Additional signs of use may include one or combinations of inks that appear and disappear and the like. Any fragrance can be used in it, including, for example, a floral essence, a fresh essence, a lavender essence, an eucalyptus essence, a pine essence, an essence of spices, and combinations thereof.

In one embodiment, a composition may include a fragrance, a carrier a volatile asset / active ingredient in an amount as depicted in Table No. 4.

In one embodiment, Compositions A, B or C, once mixed, can be applied to a substrate measuring approximately 7.5 centimeters by approximately 12.5 centimeters in an amount of approximately 2 grams total to provide a functional dispenser 10.

In another embodiment, the components of a composition, once combined, can be thoroughly mixed and dosed into the substrate 12 in any desired amount. For example, the compositions may be dosed in an amount of about 1 gram, or about 2 grams, or about 4 grams, or about 8 grams, or about 10 grams, or about 20 grams, or about 50 grams per cellulose substrate that It measures approximately 7.5 by approximately 12.5 centimeters and it has a gauge width of approximately 15 mm.

The substrate 12 is preferably capable of maintaining a dose of the composition containing the volatile asset in an even relative distribution therein, and is also capable of allowing evaporation in response to the air flow in an equal manner from all exposed surfaces. The substrate 12 may also allow capillary action of the active ingredient followed by dosing to ensure efficient distribution throughout the entire substrate 12. The dosage may be accompanied by dripping, dew, printing or any other conventional administration of a liquid composition of the substrate 12.

The dispenser 10 can be used in a first state, as shown in FIGS. 1 to 5, wherein the first portion of the wall 16 and the second portion of the wall 18 of the substrate 12 are substantially flat. One or more junction points 24 may be used to keep the dispenser 10 in the first state until a user interrupts said junction point (s) to allow the dispenser to be used in a second state, as depicted in FIGS. 6 to 11. The junction point (s) 24 may be formed during the preparation of the dispenser 10 by cutting grooves 26 and 28 in the substrate 12 by means known in the art, such as carving, to form the second portion of the wall 18, where slot 28 does not extend completely towards the bottom edge 30 of the substrate. Alternatively, or additionally, the attachment point (s) 24 may be formed of an adhesive, staple or any other chemical or mechanical based bonding means known to those skilled in the art. In addition, the attachment point (s) 24, additionally or alternatively, comprises a conventional perforated portion (s) or test strip as known to those known in the art.

To convert the dispenser 10 from the first state to the second state, a user may interrupt the junction point (s) 24 by breaking the joint or otherwise removing the impediment to allow the second portion of the wall 18 to rotate outwardly from the first portion of the wall 16 around the fold line 20. In the second state, the dispenser 10 has a substantially triangular configuration as seen in FIG. 6. In the second state, the first 16 and second 18 portion of the wall form a relatively rigid base 32 that can rest on a surface 34, thereby effectively suspending the dispenser 10 on the surface 34. In other words, the substantially triangular structure 32 is adapted to allow the dispenser 10 to have a substantially vertical orientation when placed on a horizontal surface 34. Thus, the dispenser 10 can effectively be used in either the first state when hanging from a support (not shown) or the second state when placed on the horizontal surface 34.

In one embodiment, the dispensers 10 of the present description can be sold in a package in a first state where the first 16 and the second 18 portions of the wall are substantially flat. In addition, the packaging may be made of any material that preserves the volatile material 14 within the substrate 12 during transportation and storage, such as a cellulosic material, a plastic material, and combinations thereof. In addition, the packaging can be of any configuration or useful and / or aesthetic form known to a person skilled in the art, such as a bag, a sack, a box, a laminated structure, and the like.

In one embodiment, a user can initiate the use of a dispenser 10, for example, a mosquito repellent card, by opening a bag containing one or more dispensers and removing said dispenser from the package. Then, the dispenser can be retained in a first state or converted from the first state to a second state to place the dispenser on a flat surface. Alternatively, a strap or similar article can be inserted through the opening 22 to hang the repellent plate in a room. In some embodiments, the strap or a similar article is provided so that it is attached to the dispenser when the dispenser is removed from the package. When used in a room, a dispenser may require a period of time to reach full strength. For example, it may take approximately 1/4 of a day, or about 1/2 day, or about 1 day, or about 2 days to reach full strength.

The dispensers of the present description can be used in an interior space or an exterior space. For example, a dispenser 10 may be effective against mosquitoes in a room that has a size of approximately 3 x approximately meters, approximately approximately meters, approximately approximately meters, or more or less. In addition, the dispensers of the present disclosure may have an effective duration of continuous use of approximately day, approximately days, or approximately days, approximately days, approximately 2 weeks, approximately month, or approximately 2 months, or less.

Furthermore, while not wishing to link with the theory, it is believed that volatile material 14 within the dispenser 10 may have a first emanation rate in the first state and a second emanation rate in the second state. For example, the dispenser 10 when in the first state, if placed on the horizontal surface 34, can only have the opposite side to the surface 34 exposed to the environment and therefore a minimum amount of the surface area from which the composition can emanate. In contrast, in the second state, the dispenser 10 may have a substantially vertical orientation relative to the surface that exposes a greater surface area of ​​the substrate 12 to the environment. Accordingly, in the second state, a larger amount of the composition can be released over time from the dispenser 10. In addition, it is considered that when used in the second state, the articulation of the second portion of the wall 18 from the first portion of the wall 16 allows a greater flow of air through the substrate 12 to increase the speed of emanation relative to the dispenser 10 when it is in the first state.

The dispenser of FIGS. 1 to 11A has a substantially rectangular shape and could have a dimension to have a length L1 of approximately 12.5 centimeters and a width W1 of approximately 7.5 centimeters (see FIG. 1). The second portion of the wall 18 may have a width W2 of approximately 2.5 centimeters, which may result in a first portion of the wall 16 having widths W3 and W4 on each side of the second portion of the wall of approximately 2.5 centimeters. each. However, the placement of slots 26 and 28 may vary, which allows the variation of the widths W2 to W4. In addition, the placement of the second portion of the wall 18 related to the center point C of the substrate 12 may also vary. In addition, the slots 24, 26 may be of any length required to form a second portion of the wall 18 of sufficient length to form a stable base 32 when the dispenser 10 is used in the second state. For example, the grooves can be about 2.5 centimeters, or about 5 centimeters, or about 7.5 centimeters, or shorter, or longer, and any length between them. In the modality represented in FIGS. 1 to 11 A, the opening 22, the center point C, and the second portion of the wall 18, are centered along a central axis X (see FIGS. 1 and 6) that is parallel to a side edge 36 of the substrate 12.

With reference to FIG. 11A, the dispenser 10 may further include the text 38 in either one or both of the first 16 or second 18 wall portion and also in the front and / or rear of the dispenser. In one of the examples, text 38 may include one or more instructions, such as a label, a description of the dispenser's materials, contents, and / or fragrance, a calendar that allows a user to record the day and / or date start of use and record the number of days in use, an announcement, an indication of the effective shelf life of the dispenser, an indication, an icon, an image, a logo, a description of the insects that are repelled and / or effectively eliminated by the dispenser, a statement of the disease that indicates the type of insects that carry the disease and that the dispenser repels and / or kills, an indicator of the country that indicates In which countries the dispenser can be maximally effective, a trade name, a product name, a description of the product, a warning, an avatar, as well as combinations thereof.

In one embodiment, text 38 may include instructions that direct the user to open a container (not shown) in which the dispenser 10 is carried, such as a bag, box, can, or other packaging, or direct it to remove the dispenser of said container to activate the dispenser, or to identify a space to place the activated dispenser, and place the activated dispenser substantially in the center of the identified space, such as an interior area, a room, a hall, a closet, a porch and the like. Text 38 may also include instructions that direct a user to record an initial date of use of the passive volatile dispenser in the dispenser, such as in a calendar placed therein, allowing a period of time for the dispenser to reach the total force, such as about 2 hours, or about 4 hours, or about 6 hours, or about 8 hours, and the dispenser left in space for a period of time, such as for about 3 days, or about 6 days, or up to about 7 days from the initial date of use. In addition, the instructions may direct a user to replace the dispenser 10 with a new dispenser after the effective shelf life of the dispenser has passed. In addition, the instructions may direct the user to use the dispenser in a room with a fan or in an area with air flow.

FIGS. 12 to 15 represent different modalities of dispensers 100 and 200 that are similar to dispenser 10 of FIGS. 1 to 11A. However, while dispenser 10 has an L1 that is greater than W1, for dispensers 100 and 200, W1 is greater than L1. For example, in one embodiment, while the dispenser 10 may have an L1 of approximately 12.5 centimeters and a W1 of approximately 7.5 centimeters, the dispensers 100 and 200 may have an L1 of approximately 7.5 centimeters and a W1 of approximately 12.5 centimeters. In addition, the opening 22 may be placed near the side edge 36 instead of being centered above the second portion of the wall 18. The widths W2 and W4 also differ in the dispensers 100 and 200 from that of the dispenser 10. For example, the dispenser 100 includes a width W2 which is the distance between the slots 26 and 28, which is approximately 7.5 centimeters, and widths W3 and W4 of approximately 2.5 centimeters each.

The dispenser 200 differs from the dispenser 100 in that the second portion of the wall 18 is formed in a corner of the substrate 12 by means of a single groove 26 in the substrate.

In addition, the groove 26 is centered on the substrate12, thereby providing a second portion of the wall with a width W2 of 1/2 W1. For example, when W1 is approximately 12.5 centimeters, W2 is approximately 6.3 centimeters. In addition, the dispenser 200 of the present embodiment includes a width W5 of approximately 6.3 centimeters. Alternatively, the placement of the slot 26 can be modified in conjunction with the widths W2 and W5 so as not to be centered. As shown in FIG. 15, when the dispenser 200 is used in the second state and in a substantially vertical orientation, it can have two different orientations: a first one where the bottom edge 30 is placed on a flat horizontal surface or a second one where the bottom edge is perpendicular to the surface.

FIGS. 16 and 17 illustrate a limited or interior space 300 so that an interior area, a room, a tent, a hall, a closet, a porch and the like, in which a user can place an activated dispenser 310 to repel or kill Insects, such as mosquitoes. The space 300 may be joined, at least partially, by a horizontally placed upper barrier 312, such as a roof, beam, roof, a vertically placed perimeter barrier 314, such as a wall, screen, window, curtain and the like, and a bottom barrier placed horizontally 316, such as the floor. Each of the upper barrier 312, the perimeter barrier 314 and the lower barrier 316 is typically at least partially impermeable to air currents.

In one embodiment, the lower barrier 316 of space 300 has dimensions of approximately 3 meters by approximately 3 meters, or approximately 4 meters by approximately 4 meters, or approximately 5 meters by approximately 5 meters, or approximately 1 to 10 meters by approximately 1 to 10 meters. In another embodiment, the lower barrier 316 has a surface area of ​​approximately 9 meters², or approximately 10 to 12 meters², or approximately 12 to 16 meters², or approximately 16 to 20 meters², or approximately 24 to 48 meters². In the present embodiment, the lower barrier 316 is substantially flat, however, it is contemplated that interruptions or other geometries may be applied to the lower barrier as are typically found in said spaces.

The perimeter barrier 314 may have a height of about 2 meters, or about 3 meters, or about 4 meters, or about 5 meters, or about 2 to 10 meters, and the like. The perimeter barrier is represented as a generally rectangular area that comprises flat walls as can conventionally be found in said spaces. However, it is also contemplated that the perimeter barrier may be provided with interruptions, for example, a window, door, open wall, etc. or other geometric shapes, for example, a ledge, a ledge, rounded walls, other geometric shapes of the wall extending inward or outwardly over its length or height thereof, etc.

The upper barrier 312 may have dimensions similar to those of the lower barrier 316. For example, the interior space 300 may be a conventionally rectangular room with the lower and upper wall flat, in other words, lower and upper barrier 316, 312, respectively , with generally perpendicular walls extending between them, in other words, the perimeter barrier 314. In a different embodiment, the upper barrier 312 can be provided with a different geometric shape, for example, as an angular roof as shown in FIGS. 16 and 17, which demarcates the upper limit of the interior space 300.

The space 300 may be divided into separate zones, including, for example, an upper zone or first zone 318, and a lower zone or second zone 320. The upper zone 318 may extend vertically downward from the upper barrier 312 towards a first height 322. The first height 322 may be any distance from the lower barrier 316. For example, the first height 322 may be approximately 1 meter, or approximately 2 meters, or approximately 3 meters, or approximately 4 meters, or approximately 5 meters from the lower barrier 316. In addition, the first height 322 may be determined by the average height of a given population with a particular age. For example, the first height 322 may be at or above about the average height of an adult in a country where the dispenser 310 can be used. In addition, the first height 322 may be determined with reference to the height of the upper barrier 312. For example, the first height 322 may be any distance from the upper barrier 312. In addition, the first height 322 may be approximately 1/2 meter, or about 1 meter, or about 2 meters, or about 3 meters, or about 4 meters, or about 5 meters from the upper barrier 312. The second zone 320 extends vertically downwards from the first height 322 towards the lower barrier 316. Preferably, the second zone 320 is the area normally occupied by the user of the space 300, and the first zone 318 is the remaining area of space over the area normally occupied by the user.

While each of the barriers, the upper barrier 312, the perimeter barrier 314 and the lower barrier 316 are typically at least partially impervious to air currents, there may be differential air currents within the space 300 based on the area. For example, in the first zone 318 there may be little or no air flow, but the second zone 320 may have light to moderate air currents due to heavy traffic, air flow through a window, a fan, a ventilates and the like. In one embodiment, the first zone 318 has an air flow of about 10%, or about 20%, or about 40% of the second zone 320. In another embodiment, the second zone 320 has an air flow of about 1X, or about 2X, or about 3X, or about 10X of the first zone 318. In a further embodiment, the second zone 320 may have an air flow measured in cubic meters (or meters) per second of about 0.01, or about 0.03, or about 0.5, or about 1, or about 2, or about 4, or about 8, or about 10, or about 20, or about 40. The contemplated air flow rates may also be in a range of about 0.01 to about 0.1, or about 0.03 to about 0.3, or about 0.05 to about 0.5, or about 0.1 to about 1 cubic meter (or meters) per second.

FIGS. 16 and 17 further illustrate an activated dispenser 310 suspended within the first zone 318 by means of a suspension device 324 that has been attached to a junction point

326 The dispenser 310 may be any of the dispensers as shown in FIGS. 1 to 15 or otherwise contemplated here. The suspension device 324 may include a belt, a cable, a cord, a rope, a chain, a hook or similar means attached at one end of the dispenser 310, such as an opening 328, and at the other end to the point of union 326. The suspension device 324 may be of sufficient length to allow suspension from a junction point 326 within the first zone 318, so that the dispenser 310 10 is suspended within the first zone. For example, the suspension device 324 may be approximately 30 centimeters, or approximately 40 centimeters, or approximately 60 centimeters, or approximately 1 meter in length. In one embodiment, the junction point 326 is substantially in the center 15 of the space 300, so that the dispenser 310 is substantially suspended in the center of the space or interior space 300 within the first zone 318. However, other embodiments that are contemplated include suspension of the dispenser on a wall or placement on a horizontal surface 20 (not shown), such as a table, shelf and the like, within the interior space 300 with the suspension device 324 removed or otherwise not used.
