摘要

The closure (1) has an elastic sidewall portion (2) extended in a longitudinal direction and formed at a wall of a material-delivering sleeve to be arranged. A cylindrical-shaped head portion (6) is connected with the sidewall portion, and closes a sleeve aperture, and the sidewall portion is formed around an aperture (4). The sidewall portion is formed such that the sleeve enters the closure by the aperture. The sidewall portion is arranged at the sleeve, and comprises recesses (8a) at an inside wall (8), where the closure is made of silicone, a resilient plastic-and/or rubber material.
