Title (EN) A PISTON FOR EJECTING A VISCOUS OR PLASTIC MASS
(FR) PISTON D"EJECTION D"UNE MATIERE VISQUEUSE OU PLASTIQUE
Abstract: front page image
(EN)An injection piston for use in cylindrical containers or packages (10) of the type containing viscous or plastic masses (11), such as sealing compounds and adhesives. The piston comprises a piston part (13) forming a skirt (15) as well as an arched piston top (14), and a separate piston actuating member (17) arched in a direction opposite to the piston top. An injection pressure is applied to the actuating member (17) and transmitted to the piston top (14) whereby the effective diameter of the piston top is slightly increased. An annular sealing sleeve for receiving the piston skirt (15) and the adjacent free end of the cylindrical container (10) during storage may be formed integrally with the piston actuating member (17).
(FR)Piston ejecteur utilisable dans des recipients ou empaquetages cylindrique (10) contenant des matieres visqueuses ou plastiques (11), telles que des substances d"etancheite et des adhesifs. Le piston comprend une partie (13) formant une jupe (15), une tete de piston arquee (14) et un organe separe d"actionnement du piston (17) voute dans le sens oppose a la tete du piston. Une pression d"ejection est appliquee a l"organe d"actionnement (17) et transmise a la tete du piston (14) dont l"effet augmente legerement le diametre reel de la tete du piston. Un manchon d"etancheite annulaire de reception de la jupe du piston (15) et l"extremite libre adjacente du recipient cylindrique (10) peuvent etre formees integralement avec l"organe d"actionnement du piston.
