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.
