Abstract (en)
[origin: EP2044874A2] The bag has a sealing membrane (5) arranged between a bag wall and a retaining plate (3), where the wall is made of an air-permeable filter material. An inflow opening (2) has a diameter smaller than a connection opening (4), and a support ring (12) is formed by a ring section (13). The membrane is made of flexible foam plastic material that is hardened in a welding area and the plate and is thinner than an output thickness of the membrane. The material is thickened to the thickness in an area forming a sealing ring (6) under drawing of a sealing ring-outer side (9) by the connection opening.
