Abstract

The invention relates to a plaster consisting of a flat element on which an adhesive area (2) is provided. From above, said adhesive area (2) surrounds a non-adhesive area or a pad (5) on the application side. According to the invention, the adhesive area has a first sticking area (3) which surrounds the non-adhesive area or the pad (5) and a second sticking area (4) which is located outside of the first sticking area (3) and surrounds said first sticking area (3). The force of adhesion of the first sticking area (3) (0.5-2 N/25 mm) is less than that of the second sticking area (4) (2-8 N/25 mm). This ensures that the inventive plaster sticks well but can also be removed gently. The invention also relates to a plaster strip and incision plasters.

Claims

1. A bandage, comprising:

a flat element;

a non-adhesive area mounted on said flat element;

an adhesive area surrounding said non-adhesive area, said adhesive area mounted on said flat element,

wherein said adhesive area includes a first adhesive zone and a second adhesive zone, situated outside and surrounding said first adhesive zone, and

wherein at 0.5 to 2 N/25 mm, the adhesion of said first adhesive zone is less than the adhesion of said second adhesive zone at 2 to 8 N/25 mm.

2. The bandage as defined in claim 1, wherein said flat element comprises a flat woven fabric, such as one of:

a cloth and a knit material.

3. The bandage as defined in claim 1, wherein said flat element comprises one of:

a nonwoven material, a nonwoven material lamination and a foil.

4. The bandage as defined in claim 1, wherein the bandage comprises one of an incision foil and a fixation bandage.

5. The bandage as defined in claim 1, wherein said flat element is one of multi-layered, a heterogeneous structure, and multi-layered and a heterogeneous structure.

6. The bandage as defined in claim 1, wherein the transition from a strong adhesion to a lesser adhesion is steady.

7. The bandage as defined in claim 6, wherein the transition takes place as a continuous gradient.

8. The bandage as defined in claim 6, wherein the transition takes place as a continuous, constant gradient.

9. The bandage as defined in claim 1, wherein said adhesive area comprises a first adhesive layer and a second adhesive layer applied to the first adhesive layer in one of:

the first adhesive zone and the second adhesive zone.

10. The bandage as defined in claim 9, wherein said first adhesive layer is in said second adhesive zone with strong adhesion, and said second adhesive layer is in said first adhesive zone with a lesser adhesion.

11. The bandage as defined in claim 1, further comprising:

a finger lift of the same adhesion as that of the first adhesive zone, said finger lift extending from said first inner adhesive zone of a lesser strength and as far as the edge of the bandage.

12. The bandage as defined in claim 11, wherein said finger lift comprises a strip.

13. A bandage strip, comprising:

a strip-shaped flat element;

a non-adhesive area extending in a longitudinal direction on said strip-shaped flat element; and

an adhesive layer situated on said strip-shaped flat element on either side of said non-adhesive area, extending in said longitudinal direction, said adhesive layers delimit said non-adhesive layer transversely to the longitudinal direction,

wherein said adhesive areas comprise;

a first inner adhesive zone which extends in the longitudinal direction and delimits said non-adhesive area; and

a second outer adhesive zone extending in the longitudinal direction, and

wherein at 0.5 to 2 N/25 mm the adhesion of said first adhesive zone is less than the adhesion of said second adhesive zone at 2 to 8 N/25 mm.

14. The bandage strip as defined in claim 13, wherein said flat element comprises a flat woven fabric, such as one of:

a cloth and a knit material.

15. The bandage strip as defined in claim 13, wherein said flat element comprises one of:

a nonwoven material, a nonwoven material lamination and a foil.

16. The bandage strip as defined in claim 13, wherein the bandage comprises one of:

an incision foil and a fixation bandage.

17. The bandage strip as defined in claim 13, wherein said flat element is one of:

multi-layered, a heterogeneous structure, and multi-layered and a heterogeneous structure.

18. The bandage strip as defined in claim 13, wherein the transition from a strong adhesion to a lesser adhesion is steady.

19. The bandage strip as defined in claim 18, wherein the transition takes place as a continuous gradient.

20. The bandage strip as defined in claim 18, wherein the transition takes place as a continuous, constant gradient.

21. The bandage strip as defined in claim 13, wherein said adhesive area comprises a first adhesive layer and a second adhesive layer applied to the first adhesive layer in one of the first adhesive zone and the second adhesive zone.

22. The bandage strip as defined in claim 21, wherein said first adhesive layer is in said second adhesive zone with strong adhesion, and said second adhesive layer is in said first adhesive zone with a lesser adhesion.

23. An incision bandage, comprising:

a flat element; and

an adhesive area mounted on said flat element,

wherein said adhesive area includes a first adhesive zone and a second adhesive zone, situated outside of said first adhesive zone, and

wherein at 0.5 to 2 N/25 mm, the adhesion of said first adhesive zone is less than the adhesion of said second adhesive zone at 2 to 8 N/25 mm.

24. The incision bandage as defined in claim 23, wherein said flat element comprises a flat woven fabric, such as one of a cloth and a knit material.

25. The incision bandage as defined in claim 23, wherein said flat element comprises one of :

a nonwoven material, a nonwoven material lamination and a foil.

26. The incision bandage as defined in claim 23, wherein the bandage comprises one of :

an incision foil and a fixation bandage.

27. The incision bandage as defined in claim 23, wherein said flat element is one of :

multi-layered, a heterogeneous structure, and multi-layered and heterogeneous structure.

28. The incision bandage as defined in claim 23, wherein the transition from a strong adhesion to a lesser adhesion is steady.

29. The incision bandage as defined in claim 28, wherein the transition takes place as a continuous gradient.

30. The incision bandage as defined in claim 28, wherein the transition takes place as a continuous, constant gradient.

31. The incision bandage as defined in claim 23, wherein said adhesive area comprises a first adhesive layer and a second adhesive layer applied to the first adhesive layer in one of the first adhesive zone and the second adhesive zone.
