Description

Technical Field

[0001] The invention relates to a wall-mounted metering dispenser for providing and withdrawing liquids, in particular substances with a cleaning effect or care products for body care. Background Art

[0002] Such a wall-mounted metering dispenser therefore comprises a replaceable container for a liquid, which can have both a low viscosity and a high viscosity, and a wall bracket for mounting the wall-mounted metering dispenser on a building structure, usually a wall.

[0003] The building element on which the wall-mounted metering dispenser is mounted is preferably a building wall, for example a wall in a hotel bathroom or in a sanitary facility; however, the building element can also be a piece of furniture or a special bracket or support.

[0004] A container for liquids can be fixed to a wall bracket and can be removed from the wall bracket in order to refill or replace the container. The container has a bottom area with a container bottom and a top area with a withdrawal opening opposite the bottom area, and the wall bracket has two fixing positions for the container spaced apart from each other, of which the first fixing position is provided with a holding element for fixing the bottom area of ​​the container, into which the container can be inserted or onto which the bottom area can be mounted, in order to hold the bottom area of ​​the container in a form-fitting and / or force-fitting manner in the first fixing position, and of which the second fixing position has a sleeve that can be separated from the wall bracket or can be moved relative to the wall bracket and can be fixed to the wall bracket for fixedly holding and, if necessary, inserting the top area of ​​the container.

[0005] At least when the container is mounted in the wall bracket, an extraction device for metering liquid from the container is located at an extraction opening in the top area of ​​the container. The extraction device is arranged on a sleeve for fixing the top area of ​​the container or is at least partially integrated in the sleeve.

[0006] A wall-mounted metering dispenser with a container for storing and providing a liquid and with an extraction device for extracting the liquid from the container is used, for example, in publicly accessible bathrooms or corresponding rooms in the catering industry in order to provide liquid soap. However, such metering dispensers are particularly preferably used in hotels in order to provide liquid soap, shampoo and other care products, such as lotions or the like, on a wash basin, in the area of ​​a bathtub or in a shower. Since the current type of wall-mounted metering dispenser is characterized by the ability to extract the liquid product stored in the wall-mounted metering dispenser in a metered and hygienically leak-free manner, a certain amount of liquid product can be stored at the same time to extend the use time until the dispenser needs to be refilled or until the container is necessarily replaced for a long time interval, usually several days.

[0007] Wall-mounted metering dispensers of the current type are usually designed so that the container is inserted into the wall holder upside down, that is, so that the withdrawal opening points downwards. The withdrawal of the liquid thus takes place partly by means of gravity; the user places his hand under the withdrawal device, from which the liquid falls downwards. This requires that the withdrawal device must be provided with a valve which directly or indirectly closes the top area of ​​the container and is only opened by the user to withdraw the liquid.

[0008] The valve can be opened by an operating mechanism, for example by an operating lever. However, since liquids with relatively high viscosity are usually provided in wall-mounted metering dispensers of the current type, gravity is usually not sufficient to discharge the liquid within an acceptable time when the withdrawal valve is opened. Therefore, it is known that withdrawal devices are provided with a withdrawal valve, which opens when pressure is applied to the container, in which case the container is designed to be yieldable at least in some areas for this purpose. It is provided here that the user applies pressure to the container indirectly, as described, for example, in DE 29601 918 U1, or can also act directly on the container, as is known, for example, from DE 10 2009 024 769 B2 or DE 10 2010 024 081 A1.

[0009] However, the necessity of applying pressure to the container of the metering dispenser in order to deliver the desired amount of liquid stored in the container is not optimal in all cases. This is because the user must in any case apply a certain force in order to be able to extract the liquid. This sometimes makes it difficult to meter accurately, so that more liquid is usually extracted than desired.

[0010] The operation of this known wall-mounted metering dispenser is not intuitive in all cultures. This is because both hands must be used simultaneously and the two hands have different functions in different positions, i.e. one hand of the user must be placed below the extraction device in order to catch the discharged liquid, while the other hand of the user is in another position, i.e. on the container, responsible for discharging the liquid by squeezing the container and actuating the valve. As a result, it is always possible that the discharged liquid is not caught, so that the discharged liquid is lost and the cleaning effort is increased.

[0011] If the extraction device is arranged below the container and the liquid is dispensed directly downwards, it is also difficult for some users to predict in principle where the liquid will be dispensed when the container is pressed. This is because the user usually does not view the wall-mounted metering dispenser from below, so that the dispensing opening is obscured for the user when using the wall-mounted metering dispenser. Summary of the invention

[0012] Starting from the prior art, the invention is based on the object of modifying a wall-mounted metering dispenser of the type mentioned above so that the withdrawal device is provided with a dispensing opening which is visible to the user and the user can perform an action in the region of the dispensing opening in order to dispense the liquid.

[0013] The present invention uses a wall-mounted metering dispenser for achieving the above object, most of which corresponds to the design of the teaching of DE 10 2010024 081 B1. Thus, this relates to a wall-mounted metering dispenser for providing and extracting liquids, the wall-mounted metering dispenser comprising a container for liquids and being replaceable, a wall bracket for mounting the wall-mounted metering dispenser on a building facility, and an extraction device for metering and extracting liquids from the container, in which the container has a bottom area with a container bottom and a top area with an extraction opening arranged opposite the bottom area, wherein the wall bracket has two mutually spaced fixing positions for the container, of which the first fixing position is a fixing position for the container. The fixing position is provided with a fixed retaining element for the bottom area of ​​the container, the container can be inserted into the retaining element or the container bottom can be mounted on the retaining element so as to retain the bottom area of ​​the container in a form-locking and / or force-locking manner at the first fixing position, and of the two fixing positions, the second fixing position has a sleeve, which is fixed to the wall bracket and can be separated from the wall bracket or moved relative to the wall bracket, for fixedly retaining the top area of ​​the container, and the extraction device is arranged on the sleeve or at least partially integrated in the sleeve.

[0014] This design of the wall-mounted metering dispenser makes it possible to insert the container between or into a fixed position of the wall mount and then to fix the sleeve of the second fixed position on the wall mount and to provide a special safety structure, which can only be opened with a suitable release tool or wrench in order to prevent theft on the one hand and unauthorized manipulation of the container, which should be avoided for hygienic reasons on the other hand. Only trained and authorized personnel can release the sleeve from the fixing and separate the sleeve from the wall mount or move the sleeve relative to the wall mount, so that the container is also released from the positionally fixed holding element in its bottom area and can finally be removed or replaced.

[0015] According to the present invention, in order to achieve the given purpose, the structural type of the wall-mounted metering dispenser is modified in this way, that is, the extraction device is configured as a metering pump, the metering pump includes a pump body and an operating element, the pump body can be installed in the extraction port of the container, and the pump body includes a pump chamber and a pump valve, the operating element moves relative to the container, the operating element is configured to mechanically cooperate with the pump valve and has an output port for the liquid, the output port is connected to the pump chamber via an output channel, and the operating element is guided in the sleeve.

[0016] The metering pump according to the invention thus has an operating element which is movable relative to the container and at the same time comprises an outlet for the liquid, thereby ensuring intuitive operation of the wall-mounted metering dispenser: the component located at the outlet for the liquid in the wall-mounted metering dispenser must be grasped and pressed by the user in order to effect the dispensing of the liquid.

[0017] According to the invention, the operating element of the metering pump is guided in the sleeve of the wall-mounted metering dispenser, which increases the stability of the wall-mounted metering dispenser, because the container remains unaffected by operating forces that deviate from the vertical axis of the container and are thus not intercepted by the fixed holding element at the first fixing position of the wall bracket. The sleeve also enables precise guidance of the operating element of the metering pump. When the container is replaced, the operating element does not have to be replaced at the same time, which is ultimately advantageous from the perspective of sustainability.

[0018] The wall-mounted metering dispenser according to the invention can be installed as in the prior art so that the container is oriented upside down, that is, the bottom area of ​​the container is arranged at the top and the extraction device is located at the bottom. However, the metering pump according to the invention makes it possible to extract liquid from the container without gravity assistance, so that it is preferred that the wall-mounted metering dispenser according to the invention is not installed as in the prior art, but is installed on the building installation instead. As a result, the bottom area of ​​the container is arranged at the bottom and the top area of ​​the container with the extraction device is arranged at the top. This provides a great advantage, namely that the user can directly observe the operating elements of the extraction device or the metering pump and can operate the metering pump by pressing from top to bottom.

[0019] Within the scope of the invention, the holding element for the bottom area of ​​the container can be a hook-shaped shaped part, which is embedded in a matching shaped recess in the bottom area of ​​the container. This provides a reliable positive locking hold of the container on the wall bracket and also protects the container from rotating around its vertical axis. Alternatively, the holding element for the bottom area of ​​the container can also be configured as a dish-shaped or basin-shaped shaped part, or as a basket-shaped part, in order to accommodate the bottom area of ​​the container and fix the bottom area of ​​the container in a positive and / or non-positive manner to prevent lateral sliding. This fixing function can be assumed by the basket-shaped or dish-shaped or basin-shaped holding element by means of a crimped edge or by means of a protrusion or crown-shaped tines protruding and bent on the edge side.

[0020] The second fastening point on the wall bracket preferably has a snap-on connection for fastening the sleeve to the wall bracket, which can only be released by a suitable release tool or a wrench. As already mentioned, in this way not only theft can be prevented, but also the contents of the container can be ensured to be hygienically intact at all times, because the container cannot be opened by the user or other unauthorized persons.

[0021] The extraction opening of the container of the wall-mounted metering dispenser according to the invention preferably has the shape of a bottle neck with an external thread. The sleeve that can be fixed to the wall bracket at the second fixing position and can be moved relative to the wall bracket for replacing the container preferably has an internal thread that matches the external thread of the container. That is, the container can be screwed out of the sleeve and screwed back into the sleeve for replacement or refilling, which also ensures a reliable form-fit connection and ensures that the container is fixed to the wall bracket.

[0022] In particular, when the holding element for the bottom area of ​​the container in the first fixing position is not a hook-shaped formed part which prevents the container from rotating about its vertical axis, it is particularly advantageous if the sleeve is equipped with a reverse rotation safety feature. Once the container is screwed into the sleeve, the container can no longer be separated from the sleeve without releasing the reverse rotation safety feature.

[0023] For reasons of hygiene, it is particularly preferred that the container can no longer be separated from the sleeve once the wall-mounted metering dispenser is put into use. In this case, it is preferred within the scope of the invention that the anti-reversal safety structure comprises a plurality of teeth, which are arranged to come into contact with the bottleneck of the container and / or the external thread of the bottleneck when screwed into the internal thread of the sleeve, wherein the teeth are shaped and / or designed to be elastically deformable so that the teeth only slightly impede the screwing of the external thread into the internal thread, but on the contrary achieve that the external thread cannot be screwed out of the internal thread again without destruction.

[0024] This is preferably achieved in that the sleeve is made of plastic and the teeth of the anti-reverse protection structure are formed by elastically bendable tongues molded onto the sleeve, which fit approximately tangentially onto the bottle neck or the external thread of the bottle neck.

[0025] The anti-reversal safety structure thus constructed is further assisted by the fact that the bottle neck is provided with a collar consisting of teeth in the form of a ratchet, the teeth of which are respectively provided with a flat side and a steep side, so that the teeth of the anti-reversal safety structure act as ratchets.

[0026] In the context of the invention, the outlet opening for the liquid is preferably located at the top of the outlet nozzle on the operating element, wherein the sleeve of the wall-mounted metering dispenser has a recess for the outlet nozzle, into which the outlet nozzle sinks during the pump stroke. As long as the outlet nozzle is not aligned with the recess but is rotated relative to the recess about the vertical axis of the container, a pump stroke cannot be performed and liquid cannot be dispensed. This has advantages for the transport of refill containers.

[0027] Finally, the container of the wall-mounted metering dispenser according to the invention can be provided with at least one transparent or translucent strip extending from the top region to the bottom region for reading the filling level. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] Figure 1In the isometric view shown, the embodiment of the wall-mounted metering dispenser designed according to the invention described here is shown 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 mount 2 holds the container 1 in a fixed position 3 with a fixed holding element, which in the present case is designed as a hook-shaped shaped part 4. The shaped part engages in a positively locking manner in a recess 5 in the bottom area 6 of the container 1, thereby protecting the container 1 from lateral sliding of the container 1 from the first fixing position 3 and also preventing the container 1 from rotating about its vertical axis.

[0042] A sleeve 8 is provided at the second fastening point 7 of the wall mount 2, which is inserted onto the top region 9 (hidden 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 released from the wall mount 2 by a release tool (not shown) in order to pull the container 1 together with the sleeve 8 upward out of the wall mount 2 and thereby cancel the engagement of the container 1 with the hook-shaped molded part 4. In this way, the container 1 can be replaced very easily.

[0043] In another embodiment (not shown), the holding element at the first fixing point 3 of the wall bracket 2 has another shape, in particular a dish-like or pot-like shape, so that the container 1 can be inserted into this holding element at the first fixing point 3. The holding element can alternatively also be designed in a basket-like manner or have any other arbitrary shape, so that the holding element can be combined with the sleeve 8 to reliably fix the bottom area 6 of the container 1 on the wall bracket 2.

[0044] In another embodiment (not shown), it is also possible to remove only the sleeve 8 at the second fixing location 7 and move it relative to the wall bracket 2 so that the container 1 can be removed from the sleeve 8 in order to also release it from the first fixing location 3 and remove it from the wall bracket 2.

[0045] Finally, if Figure 1 As shown in the figure, an operating element 10 of a metering pump is arranged in the top area 9 of the container 1, which is located inside the sleeve 8 and is guided by the sleeve so as to meter the liquid from the interior of the container through an extraction port (not visible here) in the top area 9 of the container 1 to an outlet channel 11, which in the present case has the shape of a outlet nozzle, and finally discharges the liquid from the outlet port 12.

[0046] The sleeve 8 has a recess 13 at its upper circumferential edge, into which the dispensing nozzle or the spout-like dispensing channel 11 can sink during a pump stroke of the operating element 10; this is because the operating element 10 is pressed downwards towards the container 1 to operate the metering pump. At this time, the liquid or care product is dispensed through the dispensing opening 12.

[0047] Figure 2 Show Figure 1 A front view of a wall-mounted metering dispenser, where the same reference numerals may be used for the features of the wall-mounted metering dispenser and reference may be made to Figure 1 Description.

[0048] exist Figure 3 In Figure 2 In the sectional view on the plane AA of FIG. 1 , further details of this embodiment are shown. The container 1 with the bottom area 6 and the top area 9, the wall bracket 2 with the first fixing point 3 and the second fixing point 7, the hook-shaped forming part 4 and the sleeve 8 embedded in the recess 5 of the container 1 together with the operating element 10 guided therein have already been described with reference to FIG. Figure 1 and 2 Detailed explanation is given.

[0049] Based on this cross-sectional view, Figure 3 It can be seen that at the second fixing position 7 there is a latching snap-in connection structure 14, by means of which the sleeve 8 is fixed to the wall bracket 2 and which can only be released by means of a release tool (not shown) in order to be able to remove the sleeve 8 from the wall bracket 2. The operating element 10 guided inside the sleeve 8 does not constitute an obstacle here because it is guided in the sleeve 8 and is not affected by the release tool.

[0050] As based on Figure 3 As can also be seen in the sectional view in FIG, the sleeve 8 is placed on the top area 9 of the container 1 so as to be positively locked and securely held in the top area. As will be described in more detail below with reference to other figures, the connection between the container 1 and the sleeve 8 is ultimately a threaded connection; since the extraction opening 15 of the container 1 is formed by the bottleneck at the top area 9 of the container, the bottleneck is provided with an external thread 16.

[0051] As reference Figure 3As can be easily seen, according to the invention, a pump body 17 with a pump chamber and a pump valve (not visible in this illustration) is installed in the extraction opening 15 of the container 1, which is designed as a bottleneck. The pump body is the pump body of a conventional metering pump on the market, so that there is no need to explain the pump chamber and the pump valve and their working principle in detail. The pump valve and the pump chamber of the pump body 17 are activated by an operating surface 18, which in turn cooperates with the operating element 10. Pressing the operating element 10 realizes the pump stroke and, as is known per se, thus realizes the discharge of liquid from the container 1 via the discharge channel 11 integrated in the operating element 10.

[0052] As will be described in more detail below with reference to other figures, the sleeve 8 has an internal thread 19 which engages with an external thread 16 at the withdrawal opening 15. As soon as the wall-mounted metering dispenser is assembled in a ready-to-use state, the anti-reversal safety structure 20 prevents the container 1 from being able to loosen from the sleeve 8 again.

[0053] Another embodiment (not shown) does not use the anti-reverse safety structure, so that all parts replaced when changing the container can be refilled and used. For reasons of sustainability, this is desirable.

[0054] Figure 4 Show Figures 1 to 3 , where the same components are also provided with the same reference numerals. As can be seen from the figure, the current embodiment of the wall-mounted metering dispenser according to the invention mainly comprises: a container 1 with a withdrawal opening 15, an external thread 16, a recess 5 and a stabilizing groove 21; a wall bracket 2 with a first fixing point 3 and a second fixing point 4 and a hook-shaped formed part 4 as a retaining element for the bottom area 6 of the container 1; a sleeve with a recess 13; a pump body 17 with an operating surface 18 and a sealing ring 26; and an operating element 10 with an outlet channel 11 and an outlet 12.

[0055] In the top region 9 of the container 1 , a toothing 22 is provided for anti-reversal protection, which will be described in detail below.

[0056] Figure 5 A top view of the sleeve 8 is shown, and Figure 6 The sleeve 8 is shown in Figure 5sectional view in plane BB in . These figures show that the sleeve 8 is provided with an internal thread 19 for accommodating the external thread 16 of the container 1. For this purpose, a certain number of teeth 23 are used as an anti-reversal safety structure 20. These teeth 23, like the entire sleeve 8, are made of polypropylene and therefore have a certain inherent elasticity. The teeth are molded onto the sleeve 8 and have the shape of tongues, which fit approximately tangentially to the bottleneck of the container 1, so that the teeth hardly cause any difficulties for screwing in the external thread 16, but do not allow the external thread 16 to be rotated out of the internal thread 19 without damage. The crown consisting of the toothed portion 22 in the top area 9 of the container 1 also ensures the realization of the following functions, such as in Figure 4 but also in the top view showing the container 1 Figure 7 The toothed portion 22 has a flat side and a steep side, respectively, so that the tooth 23 of the anti-reverse safety structure 20 acts as a pawl, and at this time, the toothed portion 22 on the container 1 is arranged in the form of a ratchet.

[0057] In addition, Figure 5 FIG. 8 shows the adaptation of the sleeve 8 to the second fixing point 7 via the snap connection 14 .

[0058] Figure 6 It is additionally shown that the sleeve 8 is additionally provided within its internal thread 19 with a receptacle 24 for the pump body 17 and a seal 25 for the outlet channel 11. The sealing ring 26 ( Figure 4 ) in the sleeve 8 rests on the contact surface 27, thereby preventing an undesired outflow of liquid at this location.

[0059] Figure 8 Use Figure 2 The front view of FIG. 1 shows a second embodiment of a wall-mounted metering dispenser designed according to the present invention. Fig. 9 A side view of this second embodiment can be seen in FIG. Figures 1 to 7 Corresponding parts of the first embodiment of the present invention are provided with the same reference numerals. In this regard, reference is made to the preceding description of the drawings, in particular to Figure 1 and 2 Description.

[0060] The second exemplary embodiment differs from the first exemplary embodiment in the design of the holding element for the bottom region 6 of the container 1 at the first fastening point 3. Figures 1 to 7 In a first embodiment of the present invention, the retaining element is designed as a hook-shaped shaped part 4, which engages in a positively locking manner in a recess 5 in the bottom area 6 of the container 1, and in particular Figure 8 and 9The second exemplary embodiment shown is equipped with a pot-shaped shaped part 28 as a retaining element for the first fastening point 3, which is provided with a higher peripheral edge 29 in order to receive the bottom area 6 of the container 1 in a form-fitting manner during a movement component oriented perpendicularly to the vertical axis of the container 1. In this way, the container 1 cannot be removed from the wall mounting 2 without releasing one of the two fastening points 3, 7.

[0061] exist Fig.10 Use in Figure 8 The front view of the wall mount 2 of the second embodiment is shown without the container 1, in order to more clearly illustrate the differences with the first embodiment with the hook-shaped shaped part 4: the second fastening point 7 is designed identically to the first embodiment, the first fastening point 3 as a retaining element has a basin-shaped shaped part 28 with a surrounding edge 29 for accommodating the bottom area 6 of the container 1. The basin-shaped shaped part 28 can be provided with a hole in the center, for example, so that any liquids that may occur (for example condensation water that has entered between the bottom area 6 of the container 1 and the surrounding edge 29 or splashing water in the shower) can flow out.
