  • the sealing membrane is sealingly in contact with the sealing wall in a closed position and, when urine or another liquid is present, is pressed away from the closed position into an open position away from the sealing wall, as a result of which a gap is formed between the sealing membrane and the sealing wall, through which the liquid flows.
