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 which 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 two closure portions that are arranged at a distance from each other along the central lengthwise axis and serve to close off the outlet orifice and further has, between the closure portions, a delivery portion that serves to deliver the substance to be dispensed, wherein said delivery portion comprises at least one recess that is indented from the cylinder wall.
Dosage-dispensing device for substances in powder- or paste form with a supply container and with a dosage-dispensing head that is connected or connectable to the supply container, said dosage-dispensing head comprising a housing with an outlet orifice of circular cross-section and 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 relative to the outlet orifice along the central lengthwise axis, wherein the delivery- and closure element in its basic configuration is of a cylindrical shape and has at least two closure portions that are arranged at a distance from each other along the central lengthwise axis and serve to close off the outlet orifice and further has, between the closure portions, a delivery portion that serves to deliver the substance to be dispensed, wherein said delivery portion comprises at least two recesses arranged one above the other that are indented from the cylinder wall, and further comprises a conveying tool which serves to convey substance to be dispensed and which is configured to be rotatable about the central lengthwise axis and supported in a way that allows translatory movement relative to the delivery- and closure element along the central lengthwise axis.
