State of the art

0002DE 29818211U a soap dispenser is known to the applicant produces significant under the name Ingo man®. Thereof Versions with metering pumps in stainless steel or plastic, foam pumps and Spray pumps known.

0003The U-shaped pump handle and the outlet of the metering of the applicant protrude above out of the housing. The lever is at the free leg ends of the U-shape pivotally supported.

0004With the pump handle, the pump is operated. The pump draws from a Reservoir fluid portions from. The portions are just so dosed that they are sufficient in the case of liquid soap for hand washing or in the case of Disinfectants adjusted to the amount required for disinfection can be.

0005The pumps come in different designs and arrangements. Typically, the pump at the upper open end of a reservoir arranged. The pump protrudes with a suction tube into the container so that the Pump is fed from below. In this configuration, the pump needs an outlet, protruding from the dispenser housing.

0006At the latest after emptying the reservoirs are to guarantee the relevant hygiene requirements necessary interventions into the dispenser, in which components be removed and cleaned, replaced, or at least topped up. These interventions are essentially determined by the above-described construction and by the special Application provides: <ul><li>The reservoir can be usually found forward. Then can the dispenser can be removed from the wall to the pump from the rear to to accomplish. In this state, all components can be replaced, cleaned or be sterilized. Between the dispenser housing and the wall plate is a Quick link provided which facilitates the removal and reinstallation.</li><li>In the simplest case only the reservoir changed to or from the Refilling be removed. The pump remains in the dispenser. For the Housing is often an outward mopping sufficient.</li><li>Come disposable packaging used, or is a common pump change required construction methods are known in which either all components at once from be removed from the housing or the entire housing can be pivoted away to allow access to the pump and the simplify storage container or a unit of both.</li></ul>

0007From the German patent application DE 28 19 661, a soap dispenser with a Known pump. There portions of liquid soap is dispensed. The soap dispenser has a supply space, which is covered by the housing. The housing is with respect to the pump and the reservoir, among other things designed to be pivotable.

The problem:

0008The free access to internal components, which are cleaned or replaced need is covered by the housing and of the outlet orifice, to ensure that the Pump and reservoir can not be contaminated from outside. Preferably, the housing of only a few smooth parts is created to turn the to avoid possibilities of housing-contamination in crevices and corners.

0009The invention is based on the object of the exchange of the reservoir and the to simplify pump, giving particular attention below to the pump is because the reservoir is usually freely accessible.

The problem solution of the invention:

0010According to the invention the object is achieved with the features of the main claim.

0011The pump connected to the reservoir may be similar as in known embodiments, front are removed. This is the first time in accordance with the invention by allowing the discharge cover, like a lid or a door, swung away running is (s. Fig. 2-4). It is no longer necessary that the complete Dispenser housing needs to be pivoted away from the support plate, as in the Soap dispenser Offenlegungsschrift DE 28 19 661 of the case. The place to Pivoting of housing parts of the dosing dispenser is on accessibility, eg for Removal and cleaning of the reservoir and / or pump, considerably reduced. This means the pump into the tightest spaces is freely accessible, which many variations of Pump removal opened as sampling:<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>

0012Advantageous embodiments of the invention which will become apparent from the dependent claims, and the drawings with the corresponding descriptions.

embodiments

0014In the drawings, an embodiment of the invention is shown. FIGS. 1-4 show a dispenser 14 with its various parts. The dispenser 14 has a multi-part housing 1 (or cap) on. The multi-part housing 1 consists of a U-shaped housing body 16, a wall plate 11 with a lock opening 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, as the bracket trained pump lever 3 and a mounting surface 12 for a reservoir 18th The reservoir 18 is shown as a dashed line in FIG. 1

0015The 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, more guides 9b for providing the pivoting movement of the outlet aperture 2 available. The guides 9a for receiving the pump 4, can also on the holders Be the discharge cover 2 attached. In Figure 2 is 13, a guide member denotes 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 from Housing body 16 pivoted away for filling and / or cleaning, in a Detent position. Here, the bow-shaped pump handle 3 can also at the Discharge cover 2 are fixed. The pump lever 3 is usually by a spring biased and therefore falls under its own weight downwards. The Discharge cover 2 is further preloaded with a spring, not shown, so that the Pivoting movement is virtually completed in use position completely alone.

0016The pump lever 3 usually consists of a stiff steel wire and has a U-shaped Ironing designed. It serves the operation of the pump 4. belongs to the pump 4 a cylindrical pump casing 5. The cylindrical pump casing 5 has, on the Underside, a suction port 6. On the upper side of the cylindrical Pump housing 5 is a pump outlet 7 (see. FIG. 2). At the pump housing 5 is above a rectangular plate 8. With the plate 8, the pump 4 is for Mounting the dispenser housing 1 in guides 9a the U-shaped housing base body 16 pushed. To release the discharge cover 2 must - if available - an actuated release button 10th

0017In all variants of the pump lever 3 remains always on the housing body 16. The Pump 4 is preferably detachably fixed to a support plate. serves to mounting preferably as in many prior art dispenser housings a guide 9a, in which the Pump 4 is inserted. The guide 9a is also configured such that they a receives conventional pump. 4 Conventional pumps 4 have a roughly cylindrical housing 5 having therein a piston moving up and down. At the lower end is the suction port 6. On top of the pump cylinder 5 is a plate 8, with which the pump 4 is pushed into the guide 9a, and the pump outlet. 7 This pump outlet 7 is extended arc-shaped, so that the user at the Using his hands comfortably in front of the dispenser housing 1 under the pump outlet 7 can hold (s. Fig. 1).

0018The housing body 16 has both a mounting surface 12 for the Reservoir 18th

0019The discharge cover 2 may have a resilient detent or on the hood other components hooks, or the outlet aperture 2 holds resiliently in use position. In use position can be fixed at the same time the pump.

0020In a first variant, for example, according to Figure 2, at the seat for the Pump plate 8 a further guide 9b, the outlet aperture 2 pivotally leads.

0021In a second variant according to Figure 3 is the holder on the housing body 16 reduced to the lead 9b for the discharge cover. 2 The holding plate 8 for receiving the pump 4 is now part of the outlet aperture. 2

0022In a third variant, analogous to Figure 3, the holder on the housing body be executed 16th The pump cylinder 5 and the outlet aperture 2 is a part.

0023For the pump lever 3 is a common elongated form of advantage. Form facilitates the operation of the pump lever 3 with the elbow. Equally a manual operation possible.
