Abstract (en)
[origin: EP1995991A2] The apparatus (104) has an inner component (110) including a film-type component sealing a through opening (111) on a side. An outer component (107) partially surrounds the inner component and includes an opening (120). The outer and the inner components are connected to each other as a single piece via a multi-component injection molding, where the outer component is made of silicon and the inner component and the film-type components are made of polyethylene such that the outer component is less hard than the inner component.
