ABSTRACT:
A device for retaining and dispensing a free-flowing substance includes a syringe-like retaining body (12) in which a retaining space (46) is formed. A displaceable piston (22) is axially introduced into the retaining space (46) and the retaining body (12) is provided with a dispensing nozzle (18) on its front end facing away from the piston (22). A locking pin (36) through which at least one transverse channel (44) passes, with an axial channel (42) branching off therefrom, is provided on the inside of the dispensing nozzle (18). In a closed position of the locking pin (36), a flow connection between the retaining space (46) and the transverse channel (44) is blocked. In an activation position of the locking pin (36), the transverse channel (44) is connected to the retaining space (46), so that the free-flowing substance can be dispensed from the retaining space (46) via the transverse channel (44) and the axial channel (42).
