An improved cartridge (10) for dispensing highly viscous fluids having a recessed nozzle (34) for ease of packaging, shipping and storing. The cartridge (10) comprises a hollow cylindrical body (18), a plunger (22) and a dispensing fitment (24). The cylindrical body (18) holds a supply of extrudable fluid contents such as lithographic ink. The plunger (22) acts as a pneumatically activated piston within the cylindrical body (18) to extrude the contents of the cartridge (10). The nozzle (34) has an open and a closed position. In the closed position the nozzle (34) does not extend beyond the top of the dispensing fitment (24). The dispenser (10) may also include a detachable nozzle extension (60) that, when attached to the nozzle (34), extends beyond the top of the fitment (24).
L'invention concerne une cartouche (10) améliorée servant à la distribution de fluides hautement visqueux, qui est pourvue d'une buse (34) en retrait, ce qui facilite son emballage, son expédition et son stockage. Ladite cartouche (10) comporte un corps (18) cylindrique creux, un plongeur (22) et un couvercle de distribution (24). Le corps (18) cylindrique contient une charge de fluide refoulable, telle que de l'encre lithographique. Le plongeur (22) agit comme un piston à actionnement pneumatique dans le corps (18) cylindrique pour refouler le contenu de la cartouche (10). La buse (34) peut prendre la position ouverte et la position fermée. Lorsqu'elle est en position fermée, la buse (34) ne dépasse pas de l'extrémité supérieure du couvercle de distribution (24). Le distributeur (10) peut également comprendre une rallonge de buse (60) amovible qui, lorsqu'elle est fixée à la buse (34), dépasse de la partie supérieure du couvercle de distribution (24).
