Abstract (en)

[origin: EP0056310A2] A cartridge for holding mastic or similar material in the barrel (100) of an applicator gun consists of an open ended hollow cylindrical member or sleeve (1) having a bore (10) therethrough which receives a piston (2) slidable in the bore in either direction. With the piston (2) at one end of the bore (10) a body of mastic material (M) is inserted in the bore at the other end for expulsion by the piston (2) therefrom when the mastic material (M) is heat softened in the gun. The arrangement is such that after full expulsion of the mastic material (M) the sleeve (1) can then be either used in a reverse position in the gun barrel (100) with a further body of mastic material (M) inserted in the sleeve (1) for expulsion by repeat operation of the piston (2), or the piston (2) can be returned along the bore (10) for similar operation. The piston (2) is preferably retained against movement out of the a sleeve (1) such as by retaining rings (13) at each end of the latter.
