PCT No. PCT/CH84/00100 Sec. 371 Date Feb. 12, 1985 Sec. 102(e) Date Feb. 12, 1985 PCT Filed Jun. 19, 1984 PCT Pub. No. WO85/00157 PCT Pub. Date Jan. 17, 1985.An additional container (29) for receiving further components is arranged in the container (21) for discharging preferably polyurethane foam. The additional container (29) receives a rod (37) cooperating with an inner cover (45) sealed in said container (29). The rod is led to the outside through a packing (31) in an additional container connection connected to the bottom (20) of container (21) and is movable into container (21) for blowing off cover (45). A disk (24) inserted in a recess of container bottom (20) and fixed by its beaded edge secures a sleeve (31) penetrated by the rod (37) constructed as an axially movable plunger. The outer and inner edges (39, 40) of sleeve (31) bring about a sealing action on in each case one radial collar (38, 39) of the plunger when rod (37) is inserted, and resiliently gives way during the axial movement of the plunger. |
