Abstract

A fastening tab that may be used with a disposable absorbent article such as a diaper, is disclosed. The fastening tab comprises a primary tape and a release tape. The primary tape may include a first and second mechanical fastener bearing region, an exposed adhesive region, and an intermediate region. The fastening tab provided may be directly attached to a nonwoven back sheet of a diaper chassis.

First claim

What is claimed is:

1. A fastening tab for a diaper, said tab comprising:
a primary tape including a primary tape substrate having a layer of primary tape adhesive arranged on a first side of the primary tape substrate; and,
a release tape joined to the primary tape, said release tape including a release tape substrate having a layer of release tape adhesive arranged on a first side of the release tape substrate;
wherein said primary tape includes:
a release tape attachment area, which is a portion of the primary tape to which the release tape is joined at its first end;
a first mechanical fastener bearing region carrying mechanical fasteners;
a second mechanical fastener bearing region carrying mechanical fasteners;
an exposed adhesive region which spans a gap between the first mechanical fastener bearing region and the second mechanical fastener bearing region; and
an intermediate region which is a portion of the primary tape between the first mechanical fastener bearing region and the release tape attachment area and which has exposed adhesive therein,

wherein the release tape attachment area is disposed between the first mechanical fastener bearing region and a manufacturer's end so that the release tape overlaps and/or covers the primary tape from the release tape attachment area to at least a portion of the second mechanical fastener bearing region,
wherein a finger-lift region that bears mechanical fasteners thereon is disposed between the second mechanical fastener bearing region and a user's end, and wherein the release tape does not overlap or cover the finger lift region.

2. The fastening tab of claim 1 , wherein the primary tape further includes a manufacturer's end portion and a user's end portion.

3. The fastening tab of claim 1 , wherein the release tape attachment area has a length of approximately 5.5 mm.

4. The fastening tab of claim 1 , wherein the primary tape, when unfolded, extends linearly and defines an overall length in the range of approximately 45 mm to approximately 20 mm.

5. The fastening tab of claim 1 , wherein the substrates are made of cloth, kraft paper, cellophane film, nonwoven webs, polymeric films, or other suitable materials or laminates.

6. The fastening tab of claim 1 , wherein the primary tape substrate is elastic and includes extruded or coextruded elastic films that are monolayers or that include suitable skins, basking, or release lining.

7. The fastening tab of claim 1 , wherein the release tape includes a fold or hinge formed in the release tape between a first end of the release tape and an opposing second end of the release tape.

8. The fastening tab of claim 1 , wherein the mechanical fasteners are hook and loop type fastening systems.

9. The fastening tab of claim 1 , wherein the mechanical fasteners are bonded to the primary tape and/or substrate by adhesive bonding, hot bonding, or ultrasonic bonding.

10. The fastening tab of claim 1 , wherein the finger-lift area is free of adhesive.

11. A disposable absorbent article including at least one fastening tab as essentially shown and described in any of the preceding claims.

12. The fastening tab of claim 1 , wherein the mechanical fasteners of the finger lift comprise hook material.

13. The fastening tab of claim 1 , wherein the second mechanical fastener bearing region carries a single lane of hook material.

14. The fastening tab of claim 1 , wherein the first mechanical fastener bearing region carries multiple lanes of hook material.

15. A disposable absorbent article comprising:
a pair of fastening tabs wherein each fastening tab comprises a primary tape and a release tape;
wherein said primary tape includes:
a release tape attachment area, which is a portion of the primary tape to which the release tape is joined at its first end;
a first mechanical fastener bearing region carrying mechanical fasteners;
a second mechanical fastener bearing region carrying mechanical fasteners;
an exposed adhesive region which spans a gap between the first mechanical fastener bearing region and the second mechanical fastener bearing region; and
an intermediate region which is a portion of the primary tape between the first mechanical fastener bearing region and the release tape attachment area and which has exposed adhesive therein,

wherein the release tape attachment area is disposed between the first mechanical fastener bearing region and a manufacturer's end so that the release tape overlaps and/or covers the primary tape from the release tape attachment area to at least a portion of the second mechanical fastener bearing region,
wherein a finger-lift region that bears mechanical fasteners thereon is disposed between the second mechanical fastener bearing region and a user's end, and wherein the release tape does not overlap or cover the finger lift region
a diaper chassis having a rear and front portion wherein the diaper chassis is constructed of a core and a backsheet; and
wherein the fastening tabs are joined to the rear portion of the diaper chassis.

16. The fastening tab of claim 13 , wherein the first mechanical fastener bearing region carries multiple lanes of hook material.
