Abstract
A device dispenses dosages of a substance in powder- or paste form contained in a supply container, when a head (1) of the device is connected to the supply container. The head has a housing with an outlet opening (107) of circular cross-section and a delivery- and closure element (100). The outlet opening and the delivery- and closure element are arranged on a central lengthwise axis (15) of the head. The delivery- and closure element rotates relative to the housing about this axis and is arranged for translatory displacement relative to the housing along the axis. The delivery- and closure element is cylindrical in its fundamental contour shape. A closure portion (101) thereof closes off the outlet opening. A delivery portion (102) is adjacent to the closure portion and delivers substance that is to be dispensed. A shaft portion is adjacent to the delivery portion. A conveyor body (103) on the delivery portion conveys substance to the outlet opening. In an operative state, the closure portion is arranged below the delivery portion, providing an end surface at a bottom end of the delivery- and closure element. A recess from the shell surface of the basically cylindrical contour sh…
