Dispenser, in Particular, Metering Dispenser
The invention concerns a dispenser, in particular for semi-solid or liquid systems, with a housing to hold a dispenser unit which is formed by a storage container, a metering unit ( 3 ) connected therewith via which the substance can be output in defined doses and an activation mechanism ( 4 ) which can activate the metering unit ( 3 ) to output a dose of substance, where the dispenser unit is held via a reservoir holder ( 5 ) in the housing ( 1 ). Known dispensers have the disadvantage that the dispenser unit is not held securely against tipping. The invention avoids this in that the storage container ( 2 ) is formed with a lower volume area ( 2 ″) and an upper volume area ( 2′ ) which to form the reservoir holder between its upper and lower end has a constricted shoulder area ( 9 ) with an inwardly angled setting surface, where the housing ( 1 ) has a corresponding support surface ( 10 ) to support the setting surface.
