Patent ID: 10311759

Abstract:
A pressure compensation label for sticking to a surface, provided with a pressure compensation opening, of a housing or some other article, has a first film for sticking to a surface provided with a pressure compensation opening, and an outer, second film and also an air-permeable membrane film which is arranged between the first film and the second film. The first film has a cutout, intended for positioning over a pressure compensation opening, and a number of ventilation ducts. Each of the ventilation ducts is separated from the cutout by a film region of the first film. The membrane film covers the cutout and each of the film regions between the cutout and the number of ventilation ducts. The outer, second film extends laterally beyond the membrane film, at least regionally covers the number of ventilation ducts of the first film laterally outside the membrane film, and spans a ventilation path which leads from that surface of the membrane film that faces the second film to the number of ventilation ducts in the first film.
