Abstract

A label with which an opening situated in a wall can be covered comprises a gas-permeable element ( 30 ) that is embedded between a base layer ( 10 ) and a top layer ( 20 ). Base layer and top layer have openings ( 11, 21 ) that overlap one another. The gas-permeable element is disposed between an adhesive layer ( 102 ) of the base layer and the top layer ( 20 ). According to embodiments, the opening of the top layer can project (A) beyond the edge of the opening of the lower layer and/or the top layer can project (B) beyond the outer edge of the lower layer. The label demonstrates sufficient mechanical stability and prevents the escape of adhesive.

First claim

The invention claimed is:

1. A label for covering an opening situated in a wall, comprising:
a base layer having an opening, wherein the base layer comprises an adhesive;
a top layer having an opening, wherein the base layer and the top layer are disposed one on top of the other, and the opening of the base layer and the opening of the top layer overlap;
a gas-permeable element, which is disposed between the top layer and the base layer that comprises the adhesive,
wherein the gas-permeable element comprises a section that lies in the region of the overlapping openings of the base layer and of the top layer, and a further section that lies between overlapping regions of the base layer and of the top layer,
wherein a side of the top layer that faces the base layer is not coated with adhesive, and a side of the base layer that faces the top layer is coated with adhesive, which contacts the top layer,
wherein one side of the gas-permeable element contacts the top layer and another side of the gas-permeable element contacts the adhesive,
wherein the top layer projects in the region of the opening of the top layer beyond the edge of the base layer that forms the opening of the base layer by 0.3 mm to 0.7 mm, and
wherein the top layer projects beyond the base layer such that an outer edge of the top layer projects beyond an outer edge of the base layer.

2. The label according to claim 1 , in which a side of the top layer that faces the base layer is not coated with adhesive, and the base layer is formed from an adhesive layer.

3. The label according to claim 1 , in which the adhesive contacts a side of the top layer that faces the base layer and a side of the gas-permeable element that faces away from the top layer.

4. The label according to claim 1 , in which the top layer comprises a plurality of openings that are smaller in comparison with the opening, which openings overlap with the one opening of the base layer.

5. The label according to claim 1 , in which the top layer comprises an opaque laser-active layer component which can be removed under the effect of a laser beam, or can be modified to such an extent that it becomes less opaque or transparent.

6. The label according to claim 1 , in which the top layer comprises a layer that is permeable for a laser beam, and comprises an opaque, laser-active layer component on its side facing the base layer, which component can be modified via the effect of a laser beam, to such an extent that it becomes less opaque or transparent, and further comprises a contrast-forming layer, which faces the base layer.

7. The label according to claim 1 , in which the gas-permeable element is a membrane that is non-permeable to liquids, or is a woven fabric that is non-permeable to liquids in the form of droplets.

8. The label according to claim 1 , in which:
the base layer is configured as a section of a double-sided adhesive tape coated on both sides with adhesive, composed of polymer film, into which tape a circular opening with a diameter is introduced;
the gas-permeable element has a cross-section that is greater than the opening of the base layer, so that the gas-permeable element completely covers the opening of the base layer;
the top layer is a polymer film that is not coated with adhesive, and contains a circular opening, the diameter of which is smaller than the diameter of the opening of the base layer, wherein
the top layer touches the gas-permeable element and is adhesively connected with a side of the adhesive tape that is coated with adhesive;
the surface of the top layer is adhesively connected with the side of the adhesive tape that is coated with adhesive, is larger than the surface of the top layer that touches the gas-permeable element; and
the top layer projects beyond the outer edge of the base layer along the entire circumference of the base layer.

9. A label for covering an opening situated in a wall, comprising:
a base layer having an opening, wherein the base layer comprises an adhesive;
a top layer having an opening, wherein the base layer and the top layer are disposed one on top of the other, and the opening of the base layer and the opening of the top layer overlap;
a gas-permeable element, which is disposed between the top layer and the base layer that comprises the adhesive,
wherein the gas-permeable element comprises a section that lies in the region of the overlapping openings of the base layer and of the top layer, and a further section that lies between overlapping regions of the base layer and of the top layer,
wherein a side of the top layer that faces the base layer is not coated with adhesive, and a side of the base layer that faces the top layer is coated with adhesive, which contacts the top layer,
wherein one side of the gas-permeable element contacts the top layer and another side of the gas-permeable element contacts the adhesive,
wherein the top layer projects beyond the base layer such that an outer edge of the top layer projects beyond an outer edge of the base layer, and
wherein the adhesive is a layer having a given thickness, and the top layer, in the region of the outer edge of the base layer, projects beyond the base layer by 8 times to 12 times the thickness of the adhesive or projects by 0.4 mm to 1.2 mm.

10. The label according to claim 9 , in which a cross-section of the opening of the top layer is smaller than a cross-section of the opening of the base layer.

11. The label according to claim 9 , in which a side of the top layer that faces the base layer is not coated with adhesive, and the base layer is formed from an adhesive layer.

12. The label according to claim 9 , in which the adhesive contacts a side of the top layer that faces the base layer and a side of the gas-permeable element that faces away from the top layer.

13. The label according to claim 9 , in which the top layer, in the region of the opening, projects beyond the edge of the base layer that forms the opening of the base layer by 0.3 mm to 0.7 mm.

14. The label according to claim 9 , in which the top layer comprises a plurality of openings that are smaller in comparison with the opening, which openings overlap with the one opening of the base layer.

15. The label according to claim 9 , in which the top layer comprises an opaque laser-active layer component which can be removed under the effect of a laser beam, or can be modified to such an extent that it becomes less opaque or transparent.

16. The label according to claim 9 , in which the top layer comprises a layer that is permeable for a laser beam, and comprises an opaque, laser-active layer component on its side facing the base layer, which component can be modified via the effect of a laser beam, to such an extent that it becomes less opaque or transparent, and further comprises a contrast-forming layer, which faces the base layer.

17. The label according to claim 9 , in which the gas-permeable element is a membrane that is non-permeable to liquids, or is a woven fabric that is non-permeable to liquids in the form of droplets.

18. The label according to claim 9 , in which:
the base layer is configured as a section of a double-sided adhesive tape coated on both sides with adhesive, composed of polymer film, into which tape a circular opening with a diameter is introduced;
