Dispenser in particular for soap and cream

p0001The invention relates to a metering device, consisting in particular as a liquid, spray or Schaumseifen-, cream or disinfectant, having a multipart housing<ol><li>a) a wall mounting,</li><li>b) a housing body with</li><li>c) a protruding outlet aperture for receiving and cover<ul><li>a removable reservoir as disposable or refill and</li><li>one for changing or cleaning removable pump over</li><li>a pump lever is actuated, </li><li>the removable pump is placed above the reservoir.</li></ul></li></ol>

State of the art

p0002From the <patcit id="pcit0001" dnum="DE8812315U"><text>DE 88 12 315 U</text></patcit> is known a generic metering.

p0003From the <patcit id="pcit0002" dnum="DE29818211U"><text>DE 29818211U</text></patcit> is a soap dispenser known to the applicant produces a considerable extent under the name Ingo man®. Of these versions with dosing pumps in stainless steel or plastic, foam pumps and spray pumps are known.

p0004The U-shaped pump handle and the outlet of the metering of the applicant stand up out of the housing. The lever is pivotally mounted at the free leg ends of the U-shape.

p0005With the pump handle, the pump is operated. The pump draws from a reservoir, the fluid portions from. The portions are just so dosed that they are sufficient in the case of liquid soap for hand washing and can be adjusted in case of disinfectants on the amount required for disinfection.

p0006The pumps come in different designs and arrangements. Typically, the pump at the upper open end of the reservoir is located. The pump protrudes with a suction tube in the container, so that the pump is fed from below. In this construction, the pump requires an outlet that protrudes from the dispenser housing.

p0007At the latest after emptying the reservoir interventions into the dispenser are to ensure the relevant hygiene standards required in which expanded and purified components, exchanged, or at least be refilled. These interventions are essentially determined by the above-described construction and by the specific application:<ul><li>The reservoir can be usually found forward. Then, the dispenser can be removed from the wall to reach the pump from the rear. In this state, all parts can be replaced, cleaned or sterilized. Between the dispenser housing and the wall plate a fast connection is provided which facilitates the removal and reinstallation.</li><li>In the simplest case only the reservoir to be changed to from or removed for refilling. The pump remains in the dispenser. For the housing has an external wiping cleaning is often sufficient.</li><li>Come disposable packaging used, or is a common pump change necessary constructions are known in which either all components are removed at once from out of the housing, or the entire housing can be swung (see, for example, the <patcit id="pcit0003" dnum="DE8812315U"><text>DE 88 12 315 U</text></patcit>) To facilitate access to the pump and the reservoir, or a unit of the two.</li></ul>

p0008From German Offenlegungsschrift <patcit id="pcit0004" dnum="DE2819661"><text>DE 28 19 661</text></patcit> discloses a soap dispenser with a pump. There portions of liquid soap is dispensed. The soap dispenser has a supply space, which is covered by the housing. The housing is opposite the pump and the reservoir, among other things designed to be pivotable.

The problem:

p0009The free accessibility to the internal components that need to be cleaned or replaced is hidden by the housing and the outlet aperture to ensure that the pump and the storage container can not be contaminated from outside. Preferably, the housing is constructed from smooth few components, again to avoid the possibilities of the housing pollution in joints and corners.

p0010The invention has for its object to simplify the exchange of the reservoir and the pump, giving particular attention below to the pump, as the reservoir is usually freely accessible.

The problem solution of the invention:

p0011According to the invention the object is achieved with the features of the main claim.

p0012In this case the pump to the reservoir may be similar to the front panel removed as in known embodiments. This is made possible according to the invention for the first time in that the outlet aperture, like a lid or a door, running pivoted away is (s.<figref idrefs="f0002 f0003 f0004">FIGS. 2-4</figref>). It is no longer necessary that the complete dispenser housing needs to be pivoted away from the holding plate, as shown at the soap dispenser Offenlegungsschrift<patcit id="pcit0005" dnum="DE2819661"><text>DE 28 19 661</text></patcit> and <patcit id="pcit0006" dnum="DE8812315U"><text>DE 88 12 315 U</text></patcit> the case is. The place for pivoting of the housing parts of the dosing dispenser is considerably reduced on accessibility, eg for removal and cleaning of the reservoir and / or pump. This means the pump into the tightest spaces is freely accessible, which opens up many variations of pump removal as removal:<ul><li>of the housing</li><li>from the outlet aperture, or</li><li>the outlet orifice and the pump are made in one part.</li></ul>

p0013Advantageous embodiments of the invention which will become apparent from the dependent claims, and the drawings with the corresponding descriptions.

embodiments

p0015In the drawings, an embodiment of the invention is shown. <figref idrefs="f0001 f0002 f0003 f0004">FIGS. 1-4</figref> show a dispenser (metering) 14 with its various parts. The dispenser 14 includes a multi-part housing 1 (or hood). The multi-part housing 1 consists of a U-shaped housing body 16, a wall plate (wall-mounted) 11 with a lock hole 15. The lock opening 15 serves to lock the housing 1 with an optional and not shown in the present embodiment shutter. The housing 1 further includes a pump 4, a discharge cover 2, designed as a bracket pump lever 3, and a mounting surface 12 for a reservoir 18. The reservoir 18 is provided as a dashed line in<figref idrefs="f0001">figure 1</figref> ready.

p0016The pump 4 is in pivoted away discharge cover 2 is freely accessible from the outside and can be replaced. There are in addition to guides 9a for receiving the pump 4, further guides 9b for providing the pivoting movement of the outlet aperture 2 available. The guides 9a for receiving the pump 4 can also be attached to the holders of the discharge cover. 2 In<figref idrefs="f0002">figure 2</figref> is denoted by 13 is a guide member which is provided at the outlet aperture 2nd This guide member 13 is guided in the guides 9b for providing the pivoting movement. The discharge cover 2 engages in use position, ie, the outlet aperture 2 is pivoted away from the housing base 16 for filling and / or cleaning, in a locking position. In this case, the bow-shaped pump lever 3 can also be fixed to the outlet aperture 2nd The pump lever 3 is normally biased by a spring and thus falls by its own weight downwards. The discharge cover 2 is further biased by a spring, not shown, so that the pivoting movement is virtually completed in use position completely alone.

p0017The pump lever 3 usually consists of a stiff steel wire and is designed as a U-shaped bracket. It is used to actuate the pump 4 to the pump 4 includes a cylindrical pump housing 5. The cylindrical pump casing 5 has an intake opening 6 at the bottom on. There is a pump outlet 7 (see On the upper side of the cylindrical pump housing. 5<figref idrefs="f0002">FIG. 2</figref>). At the pump housing 5 a rectangular plate 8 is provided above. With the plate 8, the pump 4 is pushed for mounting in the dispenser housing 1 in guides 9a of the U-shaped housing base body sixteenth To release the discharge cover 2 must - if available - an unlocking button 10 is operated.

p0018In all variants of the pump lever 3 remains always on the housing main body 16. The pump 4 is preferably detachably fixed to a support plate. For fixing preferably serves as with many well-known dispenser housings a guide 9a, in which the pump is 4 inserted. The guide 9a is also configured to receive a conventional pump. 4 Conventional pumps 4 have roughly a cylindrical housing 5 having therein a piston moving up and down. At the bottom of the suction port 6. Above is the pump cylinder 5 is a plate 8, with which the pump 4 is slid into the guide 9a and the pump outlet 7. This pump outlet 7 is extended arcuate so that the user during use can keep his hands comfortably in front of the dispenser housing 1 under the pump outlet 7 (s.<figref idrefs="f0001">Fig. 1</figref>).

p0019The housing body 16 has a mounting surface 12 at the same time for the storage container 18th

p0020The discharge cover 2 may have a resilient detent hooks on the hood or other components, or discharge cover 2 holds resiliently in use position. In use position can be fixed at the same time the pump.

p0021In a first variant, for example, according <figref idrefs="f0002">figure 2</figref>, Another guide 9b is provided on the housing for the pump plate 8, which leads the outlet aperture 2 to pivot.

p0022In a second variant according to <figref idrefs="f0003">figure 3</figref> is reduced to the housing body 16 to take the lead 9b for the outlet aperture 2 the bracket. The holding plate 8 for receiving the pump 4 is now part of the outlet aperture. 2

p0023In a third variant, analogous to <figref idrefs="f0003">figure 3</figref>be carried out on the holder housing base 16th The pump cylinder 5 and the outlet aperture 2 is a part.

p0024For the pump lever 3 is a common elongated form of advantage. The form facilitates the operation of the pump lever 3 with the elbow. Similarly, a manual operation is possible.
