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.

First claim

The invention claimed is:

1. Pressure compensation label ( 10 ) for adhesive affixation to a surface of a housing or of another article provided with a pressure compensation opening, wherein the pressure compensation label ( 10 ) has the following:
a first film ( 1 ) for adhesive affixation to a surface provided with a pressure compensation opening,
an outer, second film ( 2 ), and
an air-permeable membrane film ( 3 ), which is disposed between the first film ( 1 ) and the second film ( 2 ),
wherein the first film ( 1 ) has a recess ( 6 ) intended for positioning above a pressure compensation opening, as well as a number of ventilation channels ( 7 ), and wherein each of the ventilation channels ( 7 ) is separated from the recess ( 6 ) by a film region ( 8 ) of the first film ( 1 ),
wherein the membrane film ( 3 ) covers the recess ( 6 ) and each of the film regions ( 8 ) between the recess ( 6 ) and the number of ventilation channels ( 7 ), and
wherein the outer, second film ( 2 ) extends laterally beyond the membrane film ( 3 ), covers the number of ventilation channels ( 7 ) of the first film ( 1 ) at least in certain regions, outside of the membrane film ( 3 ), and spans a ventilation path (L), which leads from the specific surface of the membrane film ( 3 ) that faces the second film ( 2 ) all the way to the number of ventilation channels ( 7 ) of the first film ( 1 ), and
wherein the ventilation channel(s) ( 7 ) is/are further recesses of the first film ( 1 ), at a distance from the recess ( 6 ).

2. Pressure compensation label according to claim 1 , wherein each of the ventilation channels ( 7 ) leads out of the pressure compensation label ( 10 ) at an outer edge (R 1 ′) of the first film ( 1 ).

3. Pressure compensation label according to claim 1 , wherein the second film ( 2 ) has a channel exit opening ( 13 ) above an outer end ( 12 ) of each of the ventilation channels ( 7 ) of the first film ( 1 ), by means of which the ventilation channel ( 7 ) is accessible, wherein the respective channel exit opening ( 13 ) is configured in the form of a recess, punch-through, die cut, bent-up film surface, cutting line or other type of opening.

4. Pressure compensation label according to claim 1 , wherein the second film ( 2 ) is connected with the first film ( 1 ) and/or with an adhesive layer ( 4 ) disposed above it, in a contact surface region ( 9 ) situated outside of the membrane film ( 3 ), and wherein each of the ventilation channels ( 7 ) is brought closer to the membrane film ( 3 ) than the contact surface region ( 9 ).

5. Pressure compensation label according to claim 1 , wherein the first film ( 1 ) has two, three, four, six or some other multiple of ventilation channels ( 7 ), which are disposed symmetrically around the recess ( 6 ) intended for the pressure compensation opening.

6. Pressure compensation label according to claim 1 , wherein the second film ( 2 ) has upward arches in surface regions above and/or close to the ventilation channels ( 7 ) of the first film ( 1 ).

7. Article ( 20 ) having a surface ( 30 ) that has at least one pressure compensation opening ( 40 ), wherein the at least one pressure compensation opening ( 40 ) is covered with a pressure compensation label ( 10 ) according to claim 1 .

8. Pressure compensation label ( 10 ) for adhesive affixation to a surface of a housing or of another article provided with a pressure compensation opening, wherein the pressure compensation label ( 10 ) has the following:
a first film ( 1 ) for adhesive affixation to a surface provided with a pressure compensation opening,
an outer, second film ( 2 ), and
an air-permeable membrane film ( 3 ), which is disposed between the first film ( 1 ) and the second film ( 2 ),
wherein the first film ( 1 ) has a recess ( 6 ) intended for positioning above a pressure compensation opening, as well as a number of ventilation channels ( 7 ), and wherein each of the ventilation channels ( 7 ) is separated from the recess ( 6 ) by a film region ( 8 ) of the first film ( 1 ),
wherein the membrane film ( 3 ) covers the recess ( 6 ) and each of the film regions ( 8 ) between the recess ( 6 ) and the number of ventilation channels ( 7 ), and
wherein the outer, second film ( 2 ) extends laterally beyond the membrane film ( 3 ), covers the number of ventilation channels ( 7 ) of the first film ( 1 ) at least in certain regions, outside of the membrane film ( 3 ), and spans a ventilation path (L), which leads from the specific surface of the membrane film ( 3 ) that faces the second film ( 2 ) all the way to the number of ventilation channels ( 7 ) of the first film ( 1 ), and
wherein the pressure compensation label ( 10 ) has an air-permeable spacer ( 14 ) between the membrane film ( 3 ) and the second film ( 2 ).

9. Pressure compensation label according to claim 8 , wherein the spacer ( 14 ) is an air-permeable material ply ( 15 ) composed of a nonwoven, felt, cloth, woven fabric or some other type of air-permeable material.

10. Pressure compensation label ( 10 ) for adhesive affixation to a surface of a housing or of another article provided with a pressure compensation opening, wherein the pressure compensation label ( 10 ) has the following:
a first film ( 1 ) for adhesive affixation to a surface provided with a pressure compensation opening,
an outer, second film ( 2 ), and
an air-permeable membrane film ( 3 ), which is disposed between the first film ( 1 ) and the second film ( 2 ),
wherein the first film ( 1 ) has a recess ( 6 ) intended for positioning above a pressure compensation opening, as well as a number of ventilation channels ( 7 ), and wherein each of the ventilation channels ( 7 ) is separated from the recess ( 6 ) by a film region ( 8 ) of the first film ( 1 ),
wherein the membrane film ( 3 ) covers the recess ( 6 ) and each of the film regions ( 8 ) between the recess ( 6 ) and the number of ventilation channels ( 7 ), and
