Patent ID: 8197448

Claim:
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, the dispensing nozzle includes two inwardly extending ring-shaped sealing lips; a locking pin engaging the two ring-shaped sealing lips of the dispensing nozzle; at least one transverse channel passing through the locking pin and the at least one transverse channel has a diameter which is equal to or less than a distance between the two sealing lips; 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 by one of said sealing lips, and in an activation position of the locking pin, a 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.
