Description

The invention relates to a wall dispenser for providing and removing a liquid, in particular a washing-active substance or a care product for body care according to the preamble of claim 1.

Such a wall-mounted metering dispenser accordingly comprises an exchangeable container for the liquid, which can have either a low or a very high viscosity, and a wall mount for attaching the wall-mounted metering dispenser to a structure, usually a wall.

The structure to which the wall dispenser is attached is preferably a building wall, for example in a hotel bathroom or in public sanitary facilities; however, it can also be a piece of furniture or a special mount or frame.

The fluid reservoir can be attached to and removed from the wall bracket for either refilling or replacement. It has a base area with a container base and, opposite this, a head area with a removal opening, the wall bracket having two spaced-apart attachment points for the container, of which a first attachment point is provided with a stationary holding element for the base area of the container, into which the container is inserted or onto which the container bottom can be attached in order to hold the bottom area of the container in a form-fitting and/or non-positive manner at the first fastening point, and of which a second fastening point is one that can be separated from the wall bracket or moved relative to it and on the wall bracket has fixable sleeve for holding and optionally inserting the head portion of the container.

At least when the container is sitting in the wall bracket, there is a removal device for the metered removal of liquid from the container at the removal opening in the top area of the container. This removal device is arranged on the sleeve for holding the head area of the container or is at least partially integrated into it.

Wall dosing dispensers with an exchangeable container for storing and providing a liquid and with a removal device for removing liquid from the container are used, for example, in publicly accessible toilet rooms or corresponding rooms in restaurants to provide liquid soap. However, such dosing dispensers are particularly preferably used in hotels in order to provide liquid soap, hair shampoo and other care products such as lotions or the like at the sink, in the area of a bathtub or in a shower stall. Because wall dispensers of the present type are characterized in that the liquid products stored in them can be dosed and removed in a hygienically correct manner, while a certain volume of the liquid products can be kept in reserve to extend the useful life until the dispenser is refilled or the container needs to be replaced extended to longer time intervals of typically several days.

Wall dosing dispensers of the present type are usually constructed in such a way that the container is placed upside down in the wall mount, ie with a removal opening pointing downwards. The removal of the liquid takes place with partial use of gravity; a user holds his hand under the extraction device from which the liquid falls down. This means that the withdrawal device must be provided with a valve that directly or indirectly closes the head area of the container and is only opened by the user to withdraw the liquid.

The valve can be opened by means of an actuating mechanism, for example via an actuating lever. Since in a wall dispenser the However, in the present type, liquids with a relatively high viscosity are usually provided, the force of gravity is often not sufficient to dispense the liquid in an acceptable time when a bleed valve is opened. It is therefore known to provide the removal device with a removal valve which opens when pressure is applied to the container, the container being designed to be flexible at least in certain areas for this purpose. It is provided that the user, as for example in DE 296 01 918 U1 described, exerts indirect pressure on the container, or acts directly on the container, as is the case, for example, in FIG DE 10 2009 024 769 B2 or the DE 10 2010 024 081 A1 is known.

However, the need to apply pressure to the dispenser reservoir to dispense a desired amount of the liquid stored therein is not optimal in all situations. In any case, the user has to exert a certain amount of force in order to be able to remove liquid. This sometimes makes exact dosing more difficult, so that often more liquid is taken than intended.

The operation of such a well-known wall dosing dispenser is also not felt to be intuitive in every culture. This is because both hands must be in action at the same time, in different locations with different functions, i.e. one user's hand must be held under the dispensing device to collect dispensed liquid, while the user's other hand is in a different location, namely on the container , by squeezing it is responsible for dispensing the liquid and actuating the valve. It is therefore always the case that the liquid dispensed is not collected, insofar as it is lost and causes increased cleaning effort.

It is also fundamentally difficult for some users to anticipate at what point the liquid will be dispensed when the container is pressed if the removal device is arranged below the container and the liquid is dispensed directly downwards. Because the user sees usually not from below, so that when the wall dispenser is in use, the dispensing opening is hidden from him.

Proceeding from this state of the art, the object of the present invention is to modify a wall-mounted dosing dispenser of the type mentioned at the outset in such a way that the removal device is provided with a dispensing opening that is visible to the user and the user can carry out an action in the area of the dispensing opening in order to dispense liquid.

This problem is solved by a wall dispenser with the features of claim 1. Preferred configurations of the wall dispenser according to the invention are laid down in claims 2 to 11.

To solve the problem, the invention uses a design of a wall-mounted dosing dispenser, which to a large extent corresponds to the teaching of DE 10 2010 024 081 B1 is equivalent to. It is therefore a wall-mounted dosing dispenser for providing and removing a liquid, with an exchangeable container for the liquid and with a wall bracket for attaching the wall-mounted dosing dispenser to a structural facility, as well as with a removal device for the dosed removal of liquid from the container, in which the Container has a base area with a container base and, opposite this, a head area with a removal opening, in which the wall bracket has two spaced-apart attachment points for the container, of which a first attachment point is provided with a stationary holding element for the base area of the container, into which the container is inserted or onto which the container bottom can be attached in order to hold the bottom area of the container in a form-fitting and/or non-positive manner at the first fastening point, and of which a second fastening point is one that can be separated from the wall bracket or moved relative to it and on the wall bracket has a fixable sleeve for holding the head region of the container, and in which the removal device is arranged on the sleeve or is at least partially integrated into it.

This construction of a wall-mounted dosing dispenser makes it possible to insert the container between or into the attachment points of the wall bracket and then to fix the sleeve of the second attachment point on the wall bracket and to provide it with a specific safety device that can only be opened with a suitable release tool or a key. on the one hand to prevent theft and on the other hand to prevent manipulation of the container, which should be avoided for reasons of hygiene. Only trained and authorized personnel can loosen the sleeve from the fixation and separate it from the wall mount or move it relative to it, so that the container can also be detached from the stationary holding element at its bottom area and finally removed or replaced.

According to the invention, this type of wall-mounted dosing dispenser is modified in order to solve the given task in that the removal device is designed as a dosing pump which comprises a pump body with pump chamber and pump valve that can be inserted into the removal opening of the container and an actuating element that can be moved relative to the container and interacts mechanically with the pump valve is formed and has a discharge opening for the liquid, which is connected to the pump chamber via a discharge channel, the actuating element being guided in the sleeve.

The dosing pump according to the invention thus has an actuating element which can be moved relative to the container and at the same time also contains the dispensing opening for the liquid, so that intuitive operation of the wall-mounted dispenser is ensured: that component of the wall-mounted dispenser in which the dispensing opening for the liquid is must be grasped and pressed by the user to cause fluid to be dispensed.

The fact that the actuating element of the metering pump is guided in the sleeve of the wall metering dispenser according to the invention increases the stability of the wall metering dispenser because the container remains free of actuating forces that deviate from the vertical axis of the container and thus not from the stationary holding element on the first attachment point of the wall bracket would be intercepted. The sleeve also enables the actuation element of the dosing pump to be guided precisely. When replacing the container, the actuating element does not have to be replaced as well, which is ultimately very advantageous from the point of view of sustainability.

As in the prior art, the wall dispenser according to the invention can be mounted in such a way that the container is oriented upside down, ie its bottom area is arranged at the top, while the removal device is at the bottom. However, the dosing pump according to the invention makes it possible to remove the liquid from the container without the aid of gravity, so that it is preferable not to mount the wall dosing dispenser according to the invention as in the prior art, but vice versa on the structural device. The bottom area of the container is thus arranged at the bottom and the top area of the container with the removal device is arranged at the top. This offers the great advantage that a user can look directly at the actuating element of the extraction device or the metering pump and press the metering pump from top to bottom.

In the context of the present invention, the holding element for the bottom area of the container can be a hook-shaped molded part which engages in a suitably shaped recess in the bottom area of the container. This provides a secure form-fitting hold of the container on the wall bracket and also protects the container from twisting around its vertical axis. Alternatively, the holding element for the bottom area of the container can also be designed as a plate- or pan-shaped molded part or basket-like in order to accommodate the bottom area of the container and to secure it positively and/or non-positively against slipping off to the side. A basket-like, plate-like or pan-like retaining element can expediently assume this securing function with the aid of a beaded edge or with bevelled projections or crown-like prongs protruding at the edge.

The second attachment point on the wall bracket preferably has a latching snap connection for fixing the sleeve on the wall bracket, which can only be released using a suitable release tool or key. As already mentioned, not only can theft be prevented in this way, but it can also be guaranteed that the contents of the container are hygienically perfect at all times, since it cannot be opened by the user or other unauthorized persons.

The removal opening of the container of the wall dispenser according to the invention preferably has the shape of a bottle neck with an external thread. The sleeve at the second attachment point, which can be fixed to the wall mount and can be moved relative to the wall mount for replacing the container, preferably has an internal thread that fits this external thread of the container. The container can therefore be unscrewed from the sleeve for an exchange or a refilling process and screwed back into the sleeve, which also ensures a reliable form-fitting connection and attachment of the container to the wall bracket.

In particular when the holding element for the bottom area of the container at the first attachment point is not a hook-shaped molded part that prevents the container from rotating about its vertical axis, it is particularly advantageous if the sleeve is equipped with a reverse rotation lock. Once the container has been screwed into the sleeve, it can no longer be separated from the sleeve without loosening the anti-reverse device.

For reasons of hygiene it is often preferable if the container cannot be separated from the sleeve once the wall-mounted dispenser has been put into use. In this case, it is preferred within the scope of the present invention if the anti-reverse device comprises a number of teeth which are arranged in such a way that they contact the bottleneck of the container and/or its external thread when screwed into the internal thread of the sleeve, being shaped in this way and/or elastically deformable are configured such that they make it at most slightly more difficult to turn the external thread into the internal thread, but conversely have the effect that the external thread cannot be unscrewed from the internal thread again without being destroyed.

This can preferably be implemented in such a way that the sleeve is made of a plastic and the teeth of the anti-reverse device are designed from elastically bendable tongues molded onto the sleeve, which rest approximately tangentially on the bottle neck or its external thread.

Such a reverse rotation lock can be further supported by the fact that the bottle neck is provided with a ring of teeth in the manner of a ratchet wheel, each with a flat and a steep flank, so that the teeth of the reverse rotation lock act as pawls.

In the context of the present invention, the dispensing opening for the liquid is preferably at the tip of a dispensing spout on the actuating element, with the sleeve of the wall dispenser having a recess for the dispensing spout into which the dispensing spout dips during a pump stroke. As long as the dispensing spout is not aligned with the recess but is twisted relative to it about the vertical axis of the container, no pump stroke can take place and no liquid can be dispensed. This can bring advantages for the transport of a refill container.

Finally, the container of the wall dispenser according to the invention can be provided with at least one transparent or translucent strip, extending from the top area to the bottom area, for reading off the fill level.

Two exemplary embodiments of a wall-mounted dosing dispenser designed according to the invention are described and explained in more detail below with reference to the attached drawings, with the description of the figures also containing important aspects of the invention Features may be included, but the invention is not limited by the specific features described as examples.

In figure 1 is an isometric view of the exemplary embodiment described here for a wall-mounted dosing dispenser designed according to the invention as a whole. A container 1 for a care product is held by a wall mount 2, which in turn is fixed to a wall (not shown). The wall bracket 2 holds the container 1 at a first attachment point 3 fixed with a stationary holding element, which is designed as a hook-shaped molded part 4 in the present case. This engages in a recess 5 in a bottom area 6 of the container 1 in a form-fitting manner, so that the container 1 is protected against lateral slipping off the first attachment point 3 and also against rotation about its vertical axis.

At a second attachment point 7 of the wall mount 2 there is a sleeve 8 which is placed on a head area 9 (covered here) of the container 1 and in this way also holds the container 1 in a form-fitting manner on the wall mount 2 . The sleeve 8 can be detached from the wall mount 2 using a release tool (not shown) in order to pull the container 1 together with the sleeve 8 upwards out of the wall mount 2 and thereby lift it out of engagement with the hook-shaped molded part 4 . In this way the container 1 can be exchanged very easily.

In another embodiment (not shown), the holding element at the first attachment point 3 of the wall bracket 2 can have a different shape, in particular a plate- or pan-shaped form, so that the container 1 can be placed in this holding element at the first attachment point 3. Alternatively, the holding element can also be constructed like a basket or have any other shape with which it can securely fix the bottom area 6 of the container 1 in connection with the sleeve 8 on the wall bracket 2 .

Also in another embodiment (not shown), the sleeve 8 can only be loosened at the second fastening point 7 and moved relative to the wall bracket 2, so that it is possible to remove the container 1 from the sleeve 8 in order to also remove it from the first fastening point 3 and remove it from the wall bracket 2.

How figure 1 finally also makes clear, an actuating element 10 of a dosing pump is arranged on a head area 9 of the container 1, inside the sleeve 8 and guided by it, in order to Removal opening in the head region 9 of the container 1 to meter liquid from its interior into a dispensing channel 11 which in this case has the shape of a dispensing spout, and finally to dispense the liquid from a dispensing opening 12 .

The sleeve 8 has a circumferential edge at the top of a recess 13 into which the dispensing spout or the beak-shaped dispensing channel 11 can dip during a pump stroke of the actuating element 10; because the actuating element 10 is pressed down towards the container 1 in order to actuate the metering pump. Here, the liquid or the care product is dispensed through the dispensing opening 12 .

figure 2 Figure 12 is a front view of the wall-mounted dispenser figure 1 where identical reference numerals were used for its features and insofar to the description of figure 1 can be referred.

In figure 3 , a sectional view in the plane A - A figure 2 , further details of the embodiment are illustrated. The container 1 with its base area 6 and its head area 9, the wall mount 2 with the first attachment point 3 and the second attachment point 7, the hook-shaped molded part 4, which engages in the recess 5 of the container 1, and the sleeve 8 with the actuating element 10 guided therein have already been explained in more detail with reference to FIGS.

Due to the sectional view, in figure 3 at the second attachment point 7 a snap-in connection 14 can be seen, with which the sleeve 8 is secured to the wall bracket 2 and which can only be released with a release tool (not shown) in order to be able to remove the sleeve 8 from the wall bracket 2. The actuating element 10, which is guided inside the sleeve 8, is not an obstacle due to the guide in the sleeve 8 and, conversely, is not affected by the release tool.

As based on the sectional view in figure 3 is also clear, the sleeve 8 is placed on the head area 9 of the container 1 that this is held positively and securely. As will be described in more detail below with reference to the further drawings, the connection between container 1 and sleeve 8 is ultimately a screw connection; because a removal opening 15 of the container 1 is formed by a bottle neck at its head area 9, which is provided with an external thread 16.

In the designed as a bottle neck removal opening 15 of the container 1 sits, as shown in FIG figure 3 is easy to see, according to the invention a pump body 17 with pump chamber and pump valve (not visible in this illustration). It is a pump body of a commercially available dosing pump, so that a detailed description of the pump chamber and pump valve and how they work is not necessary. The pump valve and the pump chamber of the pump body 17 are activated via an actuating surface 18 which in turn interacts with the actuating element 10 . A pressure on the actuating element 10 causes a pump stroke and consequently a dispensing of liquid from the container 1 via the dispensing channel 11 integrated in the actuating element 10, as is known per se.

As will be explained in more detail below with reference to further drawings, the sleeve 8 has an internal thread 19 with which it is seated on the external thread 16 of the removal opening 15 . A reverse rotation lock 20 prevents the container 1 from being released from the sleeve 8 again as soon as the wall dispenser is assembled and ready for use.

Another embodiment (not shown) dispenses with a reverse rotation lock, so that all components that are exchanged when the container is replaced can be refilled and used again. This may be desirable for reasons of sustainability.

figure 4 is an exploded view of the wall dispenser of the Figures 1 to 3 , where again identical parts with identical reference numbers are provided. This figure makes it clear that the present exemplary embodiment of a wall-mounted dosing dispenser according to the invention essentially consists of a container 1 with the removal opening 15, the external thread 16, the recess 5 and a stabilizing groove 21, a wall bracket 2 with a first fastening point 3 and a second fastening point 7 and the hook-shaped molded part 4 as a holding element for the bottom area 6 of the container 1, consists of a sleeve 8 with a recess 13, a pump body 17 with an actuating surface 18 and a sealing ring 26, and an actuating element 10 with a dispensing channel 11 and dispensing opening 12.

In the head area 9 of the container 1 there are teeth 22 for the reverse rotation lock, as will be explained in more detail below.

figure 5 shows a plan view of the sleeve 8 while figure 6 a side sectional view of the sleeve 8 in the plane BB figure 5 shows. These representations make it clear that the sleeve 8 is provided with an internal thread 19 for receiving the external thread 16 of the container 1 . In addition, there are a number of teeth 23 as reverse rotation lock 20. These teeth 23, like the entire sleeve 8, are made of polypropylene and thus have a certain inherent elasticity. They are formed onto the sleeve 8 and are in the form of tongues which are approximately tangential to the bottle neck of the container 1, so that they hardly make it more difficult to screw in the external thread 16, but turning the external thread 16 back out of the internal thread 19 is not non-destructive to permit. The ring of teeth 22 in the head area 9 of the container 1 also ensures the latter, as shown in figure 4 , but also in figure 7 , a top view of the container 1, is clearly visible. These teeth 22 are each provided with a flat and a steep flank, so that the teeth 23 of the anti-reverse device 20 act as pawls, the teeth 22 being arranged on the container 1 in the manner of a ratchet wheel.

In figure 5 the adaptation of the sleeve 8 to the second attachment point 7 via the snap connections 14 is also shown.

figure 6 additionally makes clear that the sleeve 8 is additionally provided within its internal thread 19 with a receptacle 24 for the pump body 17 together with a seal 25 for the discharge channel 11 . The sealing ring 26 of the pump body 17 ( figure 4 ) comes to rest in the sleeve 8 on a contact surface 27, so that an undesired escape of liquid at this point is excluded.

figure 8 shows in a front view how figure 2 a second exemplary embodiment of a wall dispenser designed according to the invention. In figure 9 1 is a side view of this second embodiment. The parts of the second embodiment shown here, with the corresponding parts of the first embodiment from the Figures 1 to 7 match are provided with the same reference numerals. In that regard, the above description of figures, in particular the Figures 1 and 2 referenced.

The difference between the second exemplary embodiment and the first exemplary embodiment lies in the design of the holding element for the bottom region 6 of the container 1 at the first attachment point 3. While in the first exemplary embodiment according to FIGS Figures 1 to 7 this holding element is designed as a hook-shaped molded part 4, which engages in a form-fitting manner in a recess 5 in the bottom region 6 of the container 1, is the second exemplary embodiment, in particular that Figures 8 and 9 show, equipped with a pan-shaped molded part 28 as a holding element of the first fastening point 3, the pan-shaped molded part 28 being provided with a comparatively high peripheral edge 29 in order to positively accommodate the bottom region 6 of the container 1 with regard to a movement component oriented perpendicularly to the vertical axis of the container 1. In this way, too, the container 1 cannot be removed from the wall bracket 2 without loosening one of the two attachment points 3, 7.

In figure 10 is the wall mount 2 of the second embodiment in a front view like figure 8 , but shown without the container 1. In order to emphasize the differences from the first embodiment with its hook-shaped molded part 4 even more clearly: While the second attachment point 7 is designed identically to the first embodiment, the first attachment point 3 carries the pan-shaped molded part 28 with a peripheral edge as a holding element 29 for accommodating the bottom area 6 of the container 1. The pan-shaped molded part 28 can, for example, be provided with a hole in the middle to allow any liquids, such as condensation or splashing water in a shower stall, to get between the bottom area 6 of the container 1 and the peripheral edge 29 is to let it expire.
