Abstract

A strong, easy to use tab and slot fastening device suitable for use with disposable absorbent articles. The fastening device preferably includes a tab member and a slot member. The slot member has an inboard portion, an outboard portion and a slot. The inboard portion located laterally inboard of the outboard portion and the slot located between the inboard portion and the outboard portion. The tab member has a length, a proximal edge, a distal edge and a lip portion. The tab portion is passed through the slot of the slot member to engage the fastening device. Once passed through the slot, at least the lip portion of the tab member pivots such that it overlaps the outboard portion of the slot member to prevent the tab member from disengaging from the slot member.

Claims (26)

1. An absorbent article having a first waist region, a second waist region opposed to the first waist region and a crotch region located between the first waist region and the second waist region, a pair of longitudinal edges and a pair of end edges, the absorbent article comprising:

a topsheet:

a backsheet joined with the topsheet;

an absorbent core positioned between the topsheet and the backsheet, the absorbent core including a pair of side edges and a pair of waist edges; and

a fastening system for joining at least a portion of the first waist region with at least a portion of the second waist region to provide lateral tension therebetween the fastening system including:

a slot member disposed on the absorbent article, the slot member having an inboard portion, an outboard portion and a slot, the inboard portion located laterally inboard of the outboard portion and the slot located between the inboard portion and the outboard portion; and

a tab member disposed on the absorbent article, said tab member having a proximal edge and a distal edge, the proximal edge located laterally inward from the distal edge, wherein the tab member distal edge and proximal edge are passed througb the slot such that a portion of the proximal edge of the tab member overlaps the outboard portion of the slot member so as to fasten a portion of the first waist region with at least a portion of the second waist region.

2. The absorbent article of claim 1 wherein said the tab member is joined to the absorbent article along a line of attachment extending at least about 25 percent of the length of the tab member.

3. The absorbent article of claim 1 wherein the line of attachment is located between the proximal edge and the distal edge of the tab member.

4. The absorbent article of claim 1 wherein the line of attachment is located adjacent the distal edge of the tab member.

5. The absorbent article of claim 1 wherein the line of attachment extends at least about 50 percent of the length of the tab member.

6. The absorbent article of claim 1 wherein the line of attachment extends at least about 75 percent of the length of the tab member.

7. The absorbent article of claim 1 wherein the line of attachment extends about the full length of the tab member.

8. The absorbent article of claim 1 wherein the line of attachment is non-linear.

9. The absorbent article of claim 1 wherein the distal edge of the tab member is non-linear.

10. The absorbent article of claim 1 wherein the tab member further includes a first longitudinal end, a second longitudinal end and a central region, said first longitudinal end being displaced laterally from the central region.

11. The absorbent article of claim 10 said second longitudinal end being displaced laterally from the central region.

12. The absorbent article of claim 1 wherein the slot member is integral with the absorbent article.

13. The absorbent article of claim 1 wherein the slot member includes two or more slots.

14. The absorbent article of claim 13 wherein the slots are spaced longitudinally apart from each other.

15. The absorbent article of claim 13 wherein the slots are spaced laterally apart from each other.

16. The absorbent article of claim 1 wherein the slot member further includes an outboard edge and an inboard edge, the outboard edge being non-linear.

17. The absorbent article of claim 1 wherein the slot of the slot member is non-linear.

18. The absorbent article of claim 1 wherein the slot member further includes a first longitudinal end, a second longitudinal end and a central region, the first longitudinal end being displaced laterally from the central region.

19. The absorbent article of claim 18 said second longitudinal end being displaced laterally from the central region.

20. The absorbent article of claim 1 including two or more slot members.
