Abstract

This invention is directed to a sanitary product attachment means comprising a connection member ( 3 ) having a flexible base carrier ( 4 ), whereas on one main surface of the connection member ( 3 ) an underwear connection means ( 5 ) is present which is configured to fix the connection member ( 3 ) to a piece of underwear ( 12 ) and on the opposing main surface of the connection member ( 3 ) an absorbent member connection means ( 6 ) is present which is configured to fix the connection member ( 3 ) to the underside of an absorbent member ( 2, 2 a ).

First claim

The invention claimed is:

1. A sanitary product attachment means comprising a connection member having a flexible base carrier, wherein on one main surface of the connection member an underwear connection means is present which is configured to fix the connection member to a piece of underwear and on the opposing main surface of the connection member an absorbent member connection means is present which is configured to fix the connection member to the underside of an absorbent member, and wherein the underwear connection means comprises an adhesive coating and/or a hook element thereon;
wherein the underwear connection means is disposed on a main surface of the flexible base carrier and the absorbent member connection means is disposed on an opposing main surface of the flexible base carrier, and further wherein the adhesion of the underwear connection means to a piece of underwear is higher than the adhesion of the absorbent member connection means to a major surface of an absorbent member.

2. The sanitary product according to claim 1 , characterized in that absorbent member connection means comprises an adhesive coating.

3. The sanitary product according to claim 2 , characterized in that the absorbent member connection means comprises further layers of the flexible base carrier arranged in a stack and provided with an adhesive coating on at least one of their main surfaces, whereas 1 to 8 further layers are present.

4. The sanitary product according to claim 3 , characterized in that adjacent one edge of the flexible base carriers, a fingerlift area is defined on the major side of the base carrier coated with adhesive and which is free from the adhesive coating.

5. The sanitary product according to claim 3 , characterized in that the flexible base carriers are arranged with a lateral offset preferably in a step-wise fashion towards the underwear connection means.

6. The sanitary product according to claim 3 , characterized in that the further layers of the flexible base carrier are provided with the adhesive coating on at least a portion of their main surfaces, whereas the opposing main surface is modified to reduce tack.

7. The sanitary product according to claim 2 , characterized in that the adhesive layer, the hook and/or the loop element is separated into two or more regions, in particular in the form of several stripes, squares, oval or round dots, grids, or combinations thereof.

8. The sanitary product according to claim 2 , characterized in that, the outermost adhesive layers are covered by a release liner.

9. The sanitary product according to claim 1 , characterized in that the absorbent member connection means comprises a hook element and the underwear connection means comprises an adhesive layer and/or a hook element provided thereon.

10. The sanitary product according to claim 1 , characterized in that the absorbent member connection means comprises a loop element and the underwear connection means comprises a heat-activated adhesive coating, in particular a hot-melt adhesive coating, so that the combination of the connection member adhered to a piece of underwear is wash-resistant.

11. The sanitary product according to claim 1 , characterized in that the material of the base carrier is chosen from paper, polymeric films or nonwovens.

12. The sanitary product according to claim 1 , characterized in that the connection member comprises wings on opposing edges, which are provided with a hook element or an adhesive coating.

13. A sanitary product system comprising a sanitary product attachment means according to claim 1 and at least one absorbent member.

14. The sanitary product system according to claim 13 , characterized in that the absorbent member is a diaper, a sanitary napkin or pad, panty liner, or an incontinence pad.

15. A method of fixing a sanitary product system according to claim 13 to a piece of underwear, the method comprising the steps of fixing the connection member to the underwear with the underwear connection means and fixing the absorbent member to the connection member with the absorbent member connection means.

16. A method of exchanging a used absorbent member of a sanitary product system according to claim 13 which has been fixed to the piece of underwear, the method comprising the steps of unfixing the used absorbent member from the connection member, in particular while leaving the connection member connected to the piece of underwear, and fixing a new absorbent member to the connection member.

17. A method of exchanging a used absorbent member of a sanitary product system according to claim 13 comprising the sanitary product attachment means in claim 3 which has been fixed to the piece of underwear, the method comprising the steps of peeling the used absorbent member together with the adjacent base carrier from the stack of base carriers, in particular by grabbing the fingerlift area of this base carrier, to reveal a fresh adhesive coating on the connection member and bonding a new absorbent member to the fresh adhesive coating.

18. The method according to claim 17 , characterized in that the steps are repeated at least once.

19. The sanitary product of claim 1 , wherein a thickness of each layer of the base carrier is in a range of 5 to 100 μm.
