Abstract: The container includes a film tube 11 for flowable substances. The film t is opened and placed in a cylindrical housing 31 between a cap 33 and a movable piston 32. At the end facing the cap 33, the tube 11 is provided with a ring 20 which has a conical sealing surface 21. When the piston 32 is advanced to dispense the content of the tube 11, the sealing surface 21 is forced against a complementary conical counter surface 35 formed in the cap 33 and surrounding an outlet. The content of the tube 11 is thus prevented from reaching the inner wall of the housing.

Abstract: A dynamic mixer comprises a cylindrical chamber portion 50 the rear end of hich is closed by a sealing plate 51 provided with conical pipe sockets 58, 59 adapted for being directly inserted into outlet openings of cartridges from which the pasty components to be mixed are supplied. Due to the closed structure of the mixer housing 50, 51, contamination of the device by the components and cross-contamination between them is avoided when the mixer is removed from the cartridges. Further, the direct connection of the mixer to the cartridges results in minimum travelling distances for the components, thus low friction losses, which is particularly advantageous in case of substances of high-viscosity.
