A discharge device for a flowable substance includes at least one storage element having at least one reception chamber for a flowable substance. A carrier body including a discharge opening is provided with a pin having an axial channel and a transverse channel branching off from the axial channel. The storage element is guided on an outer side of the carrier body via at least one annular sealing lip. Discharge of the flowable substance is effected by sliding the storage element onto the pin so that the sealing lip skims over the transverse channel of the cylindrical pin and the cylindrical pin urges the flowable substance out of the reception chamber via the transverse and axial channels. In the area of the discharge opening, the carrier body includes an atomizing device that discharges the flowable substance in atomized form by a sliding of the storage element.

A device for retaining and dispensing a free-flowing substance includes a syringe-like retaining body () in which a retaining space () is formed. A displaceable piston () is axially introduced into the retaining space () and the retaining body () is provided with a dispensing nozzle () on its front end facing away from the piston (). A locking pin () through which at least one transverse channel () passes, with an axial channel () branching off therefrom, is provided on the inside of the dispensing nozzle (). In a closed position of the locking pin (), a flow connection between the retaining space () and the transverse channel () is blocked. In an activation position of the locking pin (), the transverse channel () is connected to the retaining space (), so that the free-flowing substance can be dispensed from the retaining space () via the transverse channel () and the axial channel ().
