Wall-mounted metering dispenser
A wall-mounted metering dispenser for a liquid, having a replaceable container and a wall bracket, and having a removal apparatus for removing liquid from the container in a metered manner. The wall bracket has a first fixing location having a fixed retention element for the base region of the container, and a second fixing location having a sleeve which can is separable from or movable relative to the wall bracket which retains the upper region of the container. The removal apparatus is arranged on or integrated in the sleeve and includes a metering pump having a pump chamber that is insertable in the container opening and a pump valve and an actuation element that is movable relative to the container and cooperates with the pump valve and has a liquid discharge opening connected to the pump chamber via a discharge channel. The actuation element is guided in the sleeve.
1. A wall-mounted metering dispenser for providing and removing a liquid, the dispenser comprising:
a replaceable container ( 1 ) for the liquid;
a wall bracket ( 2 ) configured for connecting the wall-mounted metering dispenser to a structural arrangement;
a removal apparatus for removing the liquid from the container ( 1 ) in a metered manner;
the container ( 1 ) comprises a base region ( 6 ) having a container base and, on an opposite side, an upper region ( 9 ) having a removal opening ( 15 );
the wall bracket ( 2 ) comprises first and second mutually spaced-apart fixing locations ( 3 , 7 ) for the container ( 1 ), the first fixing location ( 3 , 7 ) including a fixed retention element for the base region ( 6 ) of the container ( 1 ), the container ( 1 ) being insertable in or placeable on the retention element to retain the base region ( 6 ) of the container ( 1 ) in a positive-locking or non-positive-locking manner at the first fixing location ( 3 ), and the second fixing location ( 7 ) including a sleeve ( 8 ) which is separable from or movable relative to the wall bracket ( 2 ) and which is fixable to the wall bracket ( 2 ) in order to retain the upper region ( 9 ) of the container ( 1 );
the removal apparatus is arranged on the sleeve ( 8 ) or is at least partially integrated therein;
the removal apparatus comprises a metering pump which includes a pump body ( 17 ) that is insertable in the removal opening ( 15 ) of the container ( 1 ) and which has a pump chamber and pump valve and an actuation element ( 10 ) which is movable relative to the container ( 1 ) and is constructed for mechanical cooperation with the pump valve and includes a discharge opening ( 12 ) for the liquid, with the discharge opening being connected to the pump chamber via a discharge channel ( 11 ), and the actuation element ( 10 ) is guided in the sleeve ( 8 ); and
the removal opening ( 15 ) of the container ( 1 ) is a bottleneck having an outer thread ( 16 ) and the sleeve ( 8 ) has an inner thread ( 19 ) which fits in said outer thread ( 16 ), wherein the outer thread ( 16 ) on the bottleneck and the inner thread ( 19 ) of the sleeve ( 8 ) are arranged to enable at least one of a replacement or refilling operation by unscrewing the container ( 1 ) from the sleeve ( 8 ) and screwing the container ( 1 ) back into the sleeve ( 8 ).
2. The wall-mounted metering dispenser as claimed in claim 1 , wherein the retention element for the base region ( 6 ) of the container ( 1 ) comprises a hook-shaped component ( 4 ) which engages in a correspondingly shaped recess ( 13 ) in the base region of the container ( 1 ).
3. The wall-mounted metering dispenser as claimed in claim 1 , wherein the retention element for the base region ( 6 ) of the container ( 1 ) comprises a plate- or pan-shaped component ( 28 ) or a basket configured to receive the base region ( 6 ) of the container ( 1 ) and to secure the base region of the container in a positive-locking or non-positive-locking manner so as to prevent lateral sliding.
4. The wall-mounted metering dispenser as claimed in claim 3 , wherein the retention element comprises a flanged, shaped or chamfered edge ( 29 ) or projections which project peripherally and which are bent over.
5. The wall-mounted metering dispenser as claimed in claim 1 , wherein the second fixing location ( 7 ) has a snap-fitting snap-fit connection for fixing the sleeve ( 8 ) to the wall bracket ( 2 ) which is releasable only by a corresponding release tool or wrench.
6. The wall-mounted metering dispenser as claimed in claim 1 , wherein the sleeve ( 8 ) comprises a plastics material.
7. The wall-mounted metering dispenser as claimed in claim 1 , wherein the discharge opening ( 12 ) for the liquid is located at a tip of a discharge spout on the actuation element, and the sleeve ( 8 ) has a recess ( 13 ) for the discharge spout, in which the discharge spout is introduced during a pump stroke.
8. The wall-mounted metering dispenser as claimed in claim 1 , wherein the container ( 1 ) includes at least one transparent or translucent stripe, which extends from the upper region ( 9 ) as far as the base region ( 6 ), to indicate a filling level.
