Abstract:
1. A device for retaining and dispensing a free-flowing substance, comprising: a syringe-like retaining body defining a retaining space for retaining a free-flowing substance; a displaceable piston axially introduced into said retaining space; a dispensing nozzle provided on a front end of the retaining body facing away from the piston; a locking pin provided in the dispensing nozzle, said locking pin including a guide section having a first diameter and a sealing section having a second diameter, said sealing section extending toward the retaining body, said first diameter being greater than said second diameter; at least one transverse channel passing through the locking pin; and an axial channel branching off from the at least one transverse channel, whereby in a closed position of the locking pin, a flow connection between the transverse channel and the retaining space is blocked, and in an activation position of the locking pin, the flow connection between the transverse channel and the retaining space is open, so that the free-flowing substance can be dispensed from the retaining space via the transverse channel and the axial channel, wherein in the closed position, the sealing section of the locking pin extends into an outlet opening of the retaining space blocking the flow connection between the retaining space and the transverse channel and in said activation position, the sealing section of said locking pin is moved out of the outlet opening.
