Abstract
A dosage-dispensing device for substances in powder- or paste form is equipped with a supply container and a dosage-dispensing head which is connected or connectable to the supply container and has a housing with an outlet orifice of circular cross-section. The dosage-dispensing head further has a delivery- and closure element, wherein the outlet orifice and the delivery- and closure element are arranged on the central lengthwise axis of the dosage-dispensing head, and the delivery- and closure element is designed to be rotatable about the central lengthwise axis in relation to the housing and to be capable of translatory displacement along the central lengthwise axis relative to the outlet orifice. The delivery- and closure element in its basic configuration is of a cylindrical shape and has at least one closure portion that serves to close off the outlet orifice and further has, adjacent to the closure portion, a delivery portion that serves to deliver the substance to be dispensed, wherein the delivery portion has at least one recess that is indented from the cylinder wall.
