Abstract

A mounting pad comprising an adhesive layer (2), said adhesive layer being provided with a removable release liner (3). The release liner being divided into at least two sections (3A, 3B) and each of the at least two said sections of the release liner is provided with one or more score lines (4) thereby defining each section of the release liner as a strip, which renders it possible by a single straight upward pull to peel a release liner in two or more narrow strips, thereby still maintaining an even pull with small force needed to remove the release liner and using only a short pulling distance for removing the release liner from the adhesive surface.

Claims

1. A mounting pad comprising an adhesive layer, said adhesive layer further comprising a removable release liner, said release liner being divided into at least two sections, each of the at least two sections of the release liner comprising one or more score lines defining each section of the release liner as a strip, wherein each strip of each section of the release liner has a first end and a second end, each first end is provided with means to fasten the first end to a base of a packaging of the mounting pad for fixation of the release liner thereto.

2. A mounting pad according to claim 1, wherein a start position of a score line defining a first end of a section of the release liner as being different from another part of the release liner is completely cut through forming two adjacent separate edges of the release liner.

3. A mounting pad according to claim 2, wherein the two adjacent edges of the release liner form an angle of less than 30°

.

4. A mounting pad according to claim 1, wherein the first end of a section is fastened to an interior surface of the packaging for fixation of the release liner thereto.

5. A mounting pad according to claim 1, wherein a part of each section extends beyond the adhesive layer.

6. A mounting pad according to claim 5, wherein a fraction of the width of an outermost part of each section extends beyond the adhesive layer.

7. A mounting pad according to claim 6, wherein the first end of each section is shaped as a projecting part on a periphery of the release liner.

8. A mounting pad according to claim 7, wherein a projecting part extends beyond the adhesive layer.

9. A mounting pad according to claim 1, wherein the width of each section is less than half the width of the widest point of the mounting pad.

10. A mounting pad according to claim 1, wherein at least a part of the score lines comprises punched or cut dots, slots or interrupted lines.

11. A mounting pad according to claim 1, wherein the at least one score line is helically shaped.

12. A mounting pad according to claim 1, wherein each section of the release liner is helically shaped.

13. A mounting pad according to claim 1, wherein the width of each section increases toward the center of the release liner.

14. A mounting pad according to claim 1, wherein the sections are parted from one another by one uninterrupted score line.

15. A mounting pad according to claim 1, wherein each score line has a starting point near the first end of the release liner.

16. A mounting pad according to claim 1, wherein the adhesive layer is a skin friendly adhesive.

17. A mounting pad according to claim 1, wherein the release liner is made of siliconized paper.

18. A mounting pad according to claim 1, wherein the release liner comprises an aperture.

19. A mounting pad according to claim 18, wherein the aperture is placed at the central part of the mounting pad.

20. A mounting pad according to claim 1, wherein said mounting pad is substantially circular or substantially oval.

28. A method of removing a release liner from a mounting pad according to claim 1, comprising

retaining a point of each section of the release liner at the first end of the mounting pad

removing all sections of the release liner by pulling in a single pull.

21. A cannula device for subcutaneous introduction of a cannula comprising:

a housing with an upper face plate and a lower face plate and a cannula connected to the lower face plate and

a mounting pad placed in connection with the lower face plate and for securing the cannula device to the skin;

said mounting pad comprising an adhesive layer, said layer further comprising a removable release liner, each of the at least two sections of the release liner comprises one or more score lines forming each section of the release liner as a strip, each strip of each section of the release liner has a first end and a second end, each first end is provided with means to fasten the first end to a base of a packaging of the mounting pad for fixation of the release liner thereto.

22. A cannula device according to claim 21, wherein the first end of each strip is shaped as a projecting part on a periphery of the release liner.

23. A cannula device according to claim 21, wherein the maximum width of each strip is less than half a width of a widest point of the release liner.

24. A cannula device according to claim 21, wherein the release liner comprises an aperture placed in the central part of the mounting pad.

25. A cannula device according to claim 21, wherein said mounting pad is substantially circular or substantially oval.

26. A cannula device according to claim 21, wherein the cannula device is an infusion set.

27. A cannula device according to claim 21, wherein the cannula device is a transcutaneous sensor.
