DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a dispenser for liquids, in particular liquid soaps, shower gel, shampoo, disinfectants or the like comprising a mounting and a container.
Dispensers for liquids such as liquid soap or similar liquids are known. In dispensers used in wash-rooms or lavatories, a pump is frequently actuated via a key or lever using pressure or traction, which pump gives out some liquid from a container. In such dispensers, the pump is unremovably fixed to the housing, whereas the container is exchangeable. As a result, such a dispenser can only be used for one liquid since otherwise the pump would have to be continually cleaned. It is moreover disadvantageous that the pump staying in the dispenser becomes clogged or gummed up and, since such types of choking can serve as culture media for bacteria, the hygienic requirements are often no longer met. Frequent and complicated cleaning of the dispenser is unavoidable.
CH-A-547 625 discloses a dispenser for pasty liquids comprising a container and a mounting for the container. At its bottom side, the container is provided with a dispensing opening which is sealable by a valve. For dispensing an amount of the container contents, the container can be compressed anywhere.
CH-A-682 068 describes a dispenser in which the container is pivotably held at a wall surface by a suction cup.
In EP-A-0 530 789 a dispenser is suggested which includes a dispensing device which is fixed to the container and is exchanged together with the container. For mounting the container, a C-shaped holding element mountable to the wall is suggested in which the container is held with its upper and its lower end. For this purpose, a cap-like lid element is screwed at its lower end over the discharge device, which element is in turn clasped by a separate holding sleeve. This holding sleeve is fastened to the holding element via an integrated theft protection. The theft protection can be unlocked with an unlocking pin which can be introduced from outside. The two arms of the C-shaped holding element extend so far from the wall that a clamped-in cylindrical container can be encompassed and compressed by a hand. When the container is compressed, the deformation of the wall of the container is translated into an opening motion of the discharge device. As the container wall is compressed, a U-shaped holding bow mounted in the container is deformed such that a locking means connected to it is shifted and the outlet opening is cleared. The liquid to be dispensed flows out of the container until the relaxation of the container wall leads to the closing of the outlet opening via the locking means.
The dispenser described in EP-A-0 530 789 is disadvantageous in that exact doses can only insufficiently be measured. As soon as the outlet opening of the discharge device is cleared when the container wall is compressed, the liquid starts flowing out of the container at different velocities depending on its viscosity. This draining-off is not ended as long as the container is compressed.
Moreover, this dispenser is disadvantageous because of its complex and space-consuming structure. The dispenser is made up of a multitude of individual parts which have to be manufactured separately and moreover prolong the time of the assembly. Since the arms of the holding element have to be long enough for embracing the container, the arms extend relatively far into the room. Furthermore, a separate unlocking pin is necessary for unlocking.
In contrast, it is the object of the present invention to provide a dispenser allowing simple and effective dosage of different amounts of any viscous liquid. Moreover, a dispenser which is made up of a low number of individual parts and whose production and assembly is simple and inexpensive is to be provided. Such a dispenser is preferably space-saving and comprises a locking means. This object is achieved by the features of the claims.
The solution to the problem of the present invention is based on the following principle ideas.
The container of the dispenser accord
