Abstract

The invention relates to fasteners comprising a flexible planar backing provided with a fastening element on its upper side and/or on its lower side, wherein the fastener consists of at least one generally Y-shaped one-piece section defined by two opposing arms, which are separated from each other by a recess, and by a third arm joined to the two opposing arms and extending away from said recess, wherein the shape and size of said third arm correspond to the shape and size of said recess.

First claim

The invention claimed is:

1. A fastener comprising a flexible planar backing provided with a fastener element on its upper side and/or on its lower side, wherein the fastener consists of at least one generally Y-shaped one-piece section defined by two opposing arms, which are separated from each other by a recess, and by a third arm joined to the two opposing arms and extending away from said recess, wherein the shape and size of said third arm correspond to the shape and size of said recess.

2. The fastener according to claim 1 , wherein the outer edges of the opposing arms extend parallel to each other.

3. The fastener according to claim 1 , wherein the recess as well as the third arm generally have a generally rectangular contour.

4. The fastener according to claim 1 , wherein the bottom of the recess as well as the free corresponding end of the third arm comprise a widened portion.

5. The fastener according to claim 1 , wherein the backing is made of a flexible thermoplastic resin.

6. The fastener according to claim 1 , wherein each fastening element is selected from the group comprising hook members of a hook-and-loop fastener, loop members of a hook-and-loop fastener and an adhesive coat.

7. The fastener according to claim 1 , wherein the element consists of a plurality of adjacently arranged Y-shaped sections formed as a single piece, wherein one of the opposing arms of a first Y-shaped section also forms one of the opposing arms of an adjacent Y-shaped section.

8. A web of fasteners comprising a plurality of successively arranged fasteners according to claim 1 , wherein the fasteners are completely cut out apart from severable bridging segments, which connect adjacent fasteners with each other.

9. The web of fasteners according to claim 8 , wherein the web is a strip.

10. A roll of fasteners according to claim 8 .

11. A method of providing a plurality of individual fasteners, the method comprising the steps of
providing a web of fasteners according to claim 8 , and
individualizing said fasteners by severing them from said web.

12. An absorbent article ( 38 ; 44 ) comprising at least one fastener according to claim 1 .

13. A method of making absorbent articles comprising at least one fastener according to claim 1 , the method comprising the steps of
providing a web of absorbent articles,
providing a plurality of fasteners according to claim 1 , and
applying said fasteners to said absorbent articles.
