摘要

The device (1) has a sleeve (3) delimited by an inner wall (7). The internal wall is provided with a beveled sealing unit i.e. lip (10), formed on the inner wall, where the inner wall includes a flared section and an angular slope constant with respect to a central axis (4) of the sleeve. The inner wall is formed by geometrical sectors (11, 12) between which the sealing unit is placed. A large section of one of the geometrical sectors is lower than small section of the other geometrical sector adjacent to the former geometrical sector. An independent claim is also included for a mold.
