A dosage-dispensing head to comprising:

• a housing with an outlet orifice of circular cross-section;
• a delivery- and closure element, wherein the outlet orifice and the delivery- and closure element are arranged on a central lengthwise axis of the dosage-dispensing head, and the delivery- and closure element is rotatable about the central lengthwise axis in relation to the housing and is capable of translatory displacement along the central lengthwise axis relative to the outlet orifice;
• a conveying tool which serves to convey substance to be dispensed and which is rotatable about the central lengthwise axis;
• wherein the delivery- and closure element is of a generally 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 a substance to be dispensed, the delivery portion comprises at least one recess that is indented from the cylinder wall.
