Description

The invention relates to a Wanddosierspender with a wall mount, which has two support arms, between which a refill is releasably held, which refill unit comprises a reservoir and a removal opening pointing downward removal device, wherein the removal device by pressurizing the at least in a portion of the container from wherein the refill unit is movably held in the wall holder and is movable between a standby position and an actuated position, and wherein at least one actuation projection is provided on the wall mount, which in the actuation position acts on the container wall at least in its elastic portion such that the removal device is actuated.

From the DE 33 33 569 A1 is already a Wanddosierspender of the type mentioned above with a wall bracket previously known, which has two retaining arms, between which a refill unit is releasably held. This refill unit has a Storage container with a removal device, which can be actuated by pressurizing the reservoir made of elastic material at least in a partial region of the container wall. The refill unit is arranged upside down in the wall mount in such a way that the removal device points downward with its removal opening. At a projecting from the wall elbow of the wall mount a cover is hinged, which is pivotable in the direction of the refill and which pivots back in the opposite direction due to the elastic resilience of the refill placed in the interior of the cover. The refill unit is arranged between two jaws serving as operating projections, one of which is provided on the wall bracket and the other jaw on the inside of the cover housing.

The previously known Wanddosierspender is multipart and correspondingly expensive to manufacture. The voluminous cover housing requires the previously known Wanddosierspender compared to the receiving volume of its refill much more space.

From the WO 01/28397 A1 a wall dispenser is previously known, in which a refill unit is held upside down between a wall bracket and a cover housing pivotally connected thereto. At the refill unit are on opposite sides Einhängezapfen before, with which the refill unit can be hung in the region of the pivot axis between the wall bracket and cover in the prior art Wanddosierspender. The refill unit of this known Wanddosierspenders has an operable by pressurizing the refill removal device with in the use position after down facing removal opening. By pivoting the cover housing in the direction of the wall mount, the intermediate refill unit is thus squeezed, so that the removal device emits a subset of the refill medium stored in the refill unit. This wall dispenser consists of many, relatively voluminous items.

From the US 4 905 873 A a wall dispenser is previously known, which has a multi-part wall mount with a socket in which a refill with an integrally formed on the refill unit condyle can be inserted obliquely from below. The refill unit, which is held in an articulated manner on the wall bracket via the joint head, has a vertically downwardly bent subarea in which a removal device with its removal opening facing downwards is provided. By pivoting the refill unit in the direction of the wall, the pressure-actuated removal device is opened, so that a subset of the filling medium can escape. However, the installation of the refill unit in the wall bracket and the insertion of its condyle in the socket on the wall bracket is associated with a considerable effort.

From the FR 2 901 545 A1 already a Wanddosierspender is already known, which has a wall mount, in which a refill unit can be mounted upside down immovable, but replaceable. In the arranged between the wall and the refill portion of the wall bracket an actuating arm is pivotally mounted. While a projecting beyond the bottom of the refill arm end of the actuating arm can be pressed by the user in the direction of the wall, the other end of the arm rests against the elastic wall of the refill unit. By pressing the protruding Armendes the actuating arm of the opposite end of the arm is pressed against the refill unit so that it is crushed and opens the removal device. Since the lower arm end of the actuating arm but at the same time in the region of the removal opening of the sampling device, the previously known Wanddosierspender can hardly meet high hygiene standards.

From the EP 0 530 789 B1 Known already a Wanddosierspender with a C-shaped holder whose free end portions form retaining arms, between which a refill unit is releasably held, which includes a reservoir and a removal opening pointing downward with their removal device. In order to remove the reservoir from the holder and replace it if necessary, one of the support arms as the reservoir partially embraced holding sleeve configured which is releasably connected to the holder and secured thereto by means of a theft deterrent. Since the reservoir is kept exposed in the holder and druckbeaufschlagbar and since the outlet valve can be opened by pressurizing the container wall of the reservoir, the stockpiled in the reservoir fluid can be removed by manual pressure on the flexible container wall.

However, if the user has heavily soiled hands, there is the problem that with the manual operation of the reservoir and the container wall heavily contaminated and subsequent users unimpeded actuation of the previously known Wanddosierspenders can be made impossible. Also, according to the latest findings of hygiene, human beings should as little as possible touch objects by hand, that of many other, possibly unknown persons already were touched. If these findings are related to the present technical field, a wall dispenser should not be required to be operated by hand.

From the US-A-3,926,347 already a wall dispenser is already known, which can be fixed by means of a wall bracket to a wall. The wall bracket has two support arms, between which a reservoir is releasably held. On the wall bracket, a box-shaped end cover is pivotally supported, which covers the wall bracket and mounted in the wall bracket reservoir. Inside the lid of the end cover, an actuating projection is provided which is pressed upon pressurization of the end cap in the elastic container wall of the reservoir that a subset of the stored in the reservoir contents are pressed out of the container interior. In this case, the container opening of the reservoir is located on the end cover, that the container opening and provided in the end cover removal opening in a pivot position of the end cover aligned with each other and the pressed out of the reservoir contents can escape.

Since the end cover covers the reservoir, insight into the reservoir and stored therein contents is not possible and also the view-side container wall of the reservoir can not be used, for example, as an advertising space. Since the reservoir does not have a bleed valve and since the removal is instead controlled by the provided on the end cover removal opening, a change of the contents used is not readily possible and also the hygiene, especially in the area of the removal opening is much more difficult.

There is therefore in particular the task of designing a Wanddosierspender of the type mentioned in such a way that it consists of a few parts and yet continues to be hygienic, easy and reliable to use.

The achievement of this object is in the Wanddosierspender the initially mentioned Artdarin that the holding arms are detachable from each other and / or between a release position and a holding position relative to each other and that at least one support arm from a starting position against a restoring force in one, the at least one actuating projection In contrast, approximate operating position is movable.

In the wall dispenser according to the invention, the refill unit is movably held in the wall bracket and movable between a standby position and an actuated position, in which actuation position the medium stored in the reservoir can flow out into the hands of a user, for example. In this case, the Wanddosierspender on its wall mount on at least one actuating projection which acts in the operating position, the rear side of the wall bracket facing the container wall at least in an elastic portion such that the removal device is actuated. The user can thus move the reservoir on one side by pressure with the elbow or the back of the hand against the actuating projection to bring the removal of their downwardly facing removal device from its ready to its operating position, so that even with heavily soiled hands of the user Contamination of the container wall can be avoided.

In order to still be able to safely guide the reservoir from its standby position into the actuating position, the invention provides that at least one retaining arm can be moved from a starting position against a restoring force into an actuating position which is approximately the same as an actuating projection.

A particularly simple and advantageous embodiment according to the invention provides that the refill unit is held pivotably on at least one holding arm. In such an embodiment, in which the refill unit is pivotally mounted in the holder, a complicated sliding guide and the like is dispensable.

The reservoir can be conveniently removed from the wall bracket and replaced if necessary against another reservoir when at least one support arm on a fixedly mounted on a wall portion of the wall mount is releasably and / or movably held.

In order to be able to exclude unauthorized manipulations of the storage container and the contents stored therein, it is expedient if the holding arm detachably and / or movably held on the wall holder can be fixed thereto by means of an anti-theft device.

In this case, a preferred embodiment, which comprises a structurally simple, yet effective anti-theft device, provides that the holding arm, which is detachably and / or movably held on the wall mount, is held thereon by means of a latching connection, which latching connection can be unlatched by means of a preferably pin-shaped release tool, wherein the Loosening tool by a shape-adapted insertion opening in the outer wall of the wall bracket to the Locking connection can be attached.

A development according to the invention provides that the removal device has a removal valve with a valve body, which acts on a spring clip, which spring clip is so approximated to at least one Wandungsinnenseite the container wall or applied to that a container wall deforming pressurization in a longitudinal movement of the valve body from the closed position into the open position of the valve can be implemented.

Thus, even a slight rocking movement of the reservoir in the direction of the actuating projection in an opening movement of the removal device can be implemented, it is advantageous if the actuating projection acts on the container wall in the region of its opposite side of the spring clip container. This area of the container wall is the optimal pressure point for actuating the extraction valve, which ensures the operability of the extraction valve with certainty.

The reservoir can be securely and firmly and yet movably mounted in the holder when the reservoir has a, preferably closable by means of a cap container neck, and when the container neck adjacent the holding arm surrounds this with a shape-adapted and / or annular portion.

To be able to recognize the rest of the stored fluid remaining in the storage container and to be able to assess the filling state of the wall dispenser, it is advantageous if the storage container in the region of the container neck and / or the closure cap is made of a transparent and / or transparent plastic material. Is the reservoir In the region of the container neck and optionally also the closure cap made of a transparent and / or transparent plastic material, the residual amount of the stored fluid accumulating in the cap pointing downwards can be easily recognized.

The invention will be described in more detail with reference to an embodiment of the invention.

one with Fig. 1 to 5 functionally comparable wall dispenser with a triangular reservoir.

In the Fig. 1 . 2 . 5 and 6 a Wanddosierspender 1 is shown, which is intended for liquid or pasty filling media. The Wanddosierspender 1 has a wall bracket 2, which has two support arms 3, 4, between which a refill unit 5 is releasably held. The refill unit 5 comprises a storage container 6 as well as a removal device pointing downwards with its removal opening 7. In order to remove the existing from reservoir 6 and removal device refill unit 5 and replace if necessary for a full or filled with another filling medium refill unit 5, the support arms 3, 4 between a release position and a holding position relative to each other and / or movable - as here - Designed to be detachable from each other.

In Fig. 2 It can be seen that the removal device can be actuated by pressurizing the reservoir 6, which is produced at least in a partial region of the container wall made of elastic material. The refill unit 5 is kept movable in the wall bracket 2 and between the in the Fig. 1 and 2 shown ready position and an actuating position movable in which the removal device is in its open position. For this purpose, the wall dispenser 1 has on its wall mount 2 an actuation projection 9 which, in the actuation position, acts on the container wall at least in its elastic subarea in such a way that the removal device is actuated. The user can thus move the reservoir 6 by pressure with the elbow against the actuating projection 9 to bring the removal device 7 pointing down their removal device from their ready to their operating position, so that even with hygiene measures or even heavily soiled hands the user contamination of the container wall can be avoided.

From a comparison of Fig. 1 to 6 It is clear that the refill unit is held pivotable at least on the upper arm 3. By contrast, the lower holding arm 4 can be moved from an initial position against the restoring force of the elastic material of the wall mount 2 into an actuating position, in which this holding arm 4 and the subregion of the refill unit 5 that it encompasses approximate the actuating projection 9.

At the upper support arm 3 is a guide web 20 in the direction of the container bottom 21 of the reservoir 6 before; the guide web 20 is guided in a groove, not shown here, on the container bottom 21 of the reservoir 6. The movably guided in the groove Guide web 20 ensures the positional arrangement of the refill unit 5 with respect to the wall mount 2 over the entire pivoting of the refill unit 5.

From the 3 and 4 It is clear that the holder 2 has two holder portions 10, 11, each carrying one of the support arms 3, 4. While in Fig. 4 holding arm 4 shown on a fixedly mounted on the wall portion 10 of the wall bracket 2 and secured thereto by means of an anti-theft device 12, here the upper arm 3 is provided on the wall-mounted portion 10.

In Fig. 3 It can be seen that the free end portion of the support arm 3 is L-shaped and the container bottom 20 of the reservoir 6 overlaps. In this case, the free end portion of the support arm 3 engages in a recess 23 of the reservoir 6 in the corner between the container bottom 21 and the visible side of the container. At the free end of the support arm 3 in the direction of the reservoir 6 projecting web 22 or the like projection is provided which pressurizes the reservoir 6 and prevents rattling of the refill unit 5 in the wall bracket 2.

Additionally or alternatively, an anti-theft device can also be provided on the upper support arm 3, which secures the refill unit 5 in the wall mount 2. Thus, for example, the upper arm 3 can be movably held on the wall bracket 2 and get its mobility after unlocking the anti-theft device.

In the Fig. 1 to 4 It can be seen that the holding arm 4, which is detachably and / or movably held on the wall mount 2, is held thereon by means of a latching connection 13 which Locking connection 13 can be unlocked by means of a release tool, wherein the release tool not shown here can be attached by a mating insertion opening in the outer wall of the wall bracket to the latching connection 13. The release tool can be wedge-shaped or otherwise shape-adapted, with the tip of the release tool locking connection between the support arm 4 and the wall bracket 2 can be solved.

In Fig. 2 It is shown that the removal device has a removal valve 14 with a valve body 15, which acts on a spring clip 16, which spring clip 16 is so approximated to at least one Wandungsinnenseite the container or it rests that a container wall deforming pressurization in a longitudinal movement of the valve body 15th from the closed position into the open position of the valve 14 can be implemented. The reservoir 6 has a closable by means of a cap 17 container neck, which surrounds the container neck adjacent holding arm 4 with an annular and designed as a holding sleeve 18 portion. In the closure cap 17, the removal opening 7 is provided. While the rod-shaped valve body 15 with its free end of the rod tightly engages the removal opening 7 bounding edge region of the cap 17, the valve body 15 is lifted in the open position of the valve 14 of this edge region such that the filling medium located in the reservoir 6 can flow through the discharge opening 7 ,

The remaining in the reservoir 6 remaining amount of the fluid always accumulates in the cap 17 at. Since the reservoir 6 in the region of its container neck and the cap 17 are made of a transparent and / or transparent plastic material, which can be in the reservoir 6 always estimate and assess the remaining amount of the filling material in order to replace the reservoir 6 as needed in time against a full and / or filled with another filling medium reservoir 6 can.

On the other hand, the holding arm 4 has a cross-sectional weakening in the region between the holding sleeve 18 on the one hand and its arm end engaging on the holder subregion 11, which promotes the mobility of the holding sleeve 18, and the force transmission of the force exerted on the refill unit 5 during the removal process is also on the wall mount 2 is reduced and formed here by a transverse groove 24 on the underside of the support arm 4.

From a comparison of Fig. 1 to 5 on the one hand and the in Fig. 6 On the other hand, it becomes clear that differently shaped, filled or otherwise different refill units 5 can also be used in the wall mount 2 of the wall dispenser 1. While the refill unit 5 in the Fig. 1 to 5 shown wall dispenser 1 has a drop-shaped reservoir 6, the refill unit 5 of in Fig. 6 illustrated embodiment, a triangular reservoir.

Since the refill units 5 are held movably and in particular pivotably in the wall brackets 2, and since the refill units 5 can be moved out of their ready position into their actuated position, in which the actuation projection 9 acts on the elastic container wall, a wall dispenser 1 is shown for actuating the wall dispenser 1 shown here Pressurization of the reservoir 6 on the visual or outside with the elbow or with the back of the hand sufficient, while the actuating projection simultaneously on the pressurization on the wall bracket 2 side facing causes. Since thus a transmission of germs during actuation of the wall dispenser 1 shown here is avoided, the Wanddosierspender 1 shown here are characterized by increased acceptance in the user circles in question.

In the FIGS. 5 and 6 is indicated that the support arm 3 is roof-shaped or convex formed on its upper side 25, such that water impinging on the support arm 3 more easily roll off to the sides of the support arm 3 and can drain down from there.
