Abstract

The present disclosure relates to absorbent articles having a first belt and a second belt with one or more frangible pathways. A frangible pathway may extend between a proximal terminus on an inner edge of a belt and a distal terminus on an outer edge of the belt. A grip region comprising an accessibility opening may be positioned between the inner and outer edges of the belt. The frangible pathway may comprise a first tear zone and a second tear zone extending from the accessibility opening to the distal terminus and to the proximal terminus. Such frangible pathway configurations provide a feature that allows a belt of a diaper pant to be relatively easily torn along the frangible pathway when removing the diaper pant from a wearer. The frangible pathway may be configured to allow a caregiver to initiate and/or completely tear the first belt with one hand.

First claim

What is claimed is:

1 . An absorbent article comprising:
a chassis comprising a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet, the chassis further comprising a first end region and a second end region longitudinally separated from the first end region by a crotch region; a first belt comprising a first end region and a second end region laterally separated from the first end region by a central region, the first end region of the chassis connected with the central region of the first belt, the first belt further comprising a laterally extending inner edge and a laterally extending outer edge, the outer edge positioned longitudinally outward of the inner edge; a second belt comprising a first end region and a second end region laterally separated from the first end region by a central region, the second end region of the chassis connected with the central region of the second belt, wherein the first end region of the first belt is connected with the first end region of the second belt and the second end region of the first belt is connected with the second end region of the second belt to form a waist opening; an accessibility opening in the first belt positioned between the outer edge and the inner edge; and a frangible pathway in the first belt extending between a proximal terminus on the inner edge of the first belt and a distal terminus on the outer edge of the first belt, the frangible pathway comprising a first tear zone extending from the accessibility opening to the distal terminus, and a second tear zone extending from the accessibility opening to the proximal terminus; and wherein the first belt further comprises an inner wearer facing surface and an outer garment facing surface, and further comprising a fastener component connected with the inner wearer facing surface of the first belt adjacent the accessibility opening, the fastener component adapted to refastenably connect with at least one other component of the absorbent article.

2 . The absorbent article of claim 1 , wherein the accessibility opening is positioned in the central region of the first belt.

3 . The absorbent article of claim 1 , wherein the first end region of the first belt is connected with the first end region of the second belt at a first side seam, and wherein the proximal terminus and the distal terminus are positioned laterally between the accessibility opening and the first side seam.

4 . The absorbent article of claim 1 , wherein the accessibility opening comprises a slit in the first belt.

5 . The absorbent article of claim 4 , wherein the slit extends along a line in a lateral direction to define a length of about 5 mm to about 50 mm and an angle from about 0 degrees to about 45 degrees with respect to the outer edge of the first belt.

6 . The absorbent article of claim 1 , wherein the frangible pathway comprises lines of weakness.

7 . The absorbent article of claim 1 , wherein the accessibility opening extends through the fastener component and divides the fastener component into at least two parts.

8 . The absorbent article of claim 1 , wherein the fastener component is positioned between the inner wearer facing surface of the first belt and the backsheet.

9 . The absorbent article of claim 8 , wherein the fastener component comprises hooks, and wherein the hooks extend toward the backsheet.

10 . The absorbent article of claim 1 , wherein both the accessibility opening and frangible pathway extend through the fastener component and divides the fastener component into at least two parts.

11 . The absorbent article of claim 10 , wherein the accessibility opening is curved and extends in a longitudinal direction.

12 . The absorbent article of claim 1 , wherein the frangible pathway defines an overall length that is greater than a longitudinal length of the first belt.

13 . An absorbent article comprising:
a chassis comprising a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet, the chassis further comprising a first end region and a second end region longitudinally separated from the first end region by a crotch region; a first belt comprising a first end region and a second end region laterally separated from the first end region by a central region, the first end region of the chassis connected with the central region of the first belt, the first belt further comprising a laterally extending inner edge and a laterally extending outer edge, the outer edge positioned longitudinally outward of the inner edge; a second belt comprising a first end region and a second end region laterally separated from the first end region by a central region, the second end region of the chassis connected with the central region of the second belt, wherein the first end region of the first belt is connected with the first end region of the second belt at a first side seam and wherein the second end region of the first belt is connected with the second end region of the second belt at a second side seam to form a waist opening; and a grip region in the central region positioned between the inner edge and the outer edge of the first belt, wherein the grip region comprises an accessibility opening positioned in the central region of the first belt and a fastener component positioned adjacent the accessibility opening; a frangible pathway in the first belt comprising a first tear zone and a second tear zone and extending between a proximal terminus on the inner edge and a distal terminus on the outer edge of the first belt, wherein upon application of a pulling force to the grip region in a direction toward the first side seam and/or outward away from the first belt, tear lines simultaneously propagate along the first tear zone and the second tear zone laterally outward from the central region of the first belt to the first end region of the first belt; and wherein the first belt further comprises an inner wearer facing surface and an outer garment facing surface, and wherein the fastener component is connected with the inner wearer facing surface of the first belt adjacent the accessibility opening.

14 . The absorbent article of claim 13 , wherein the first belt is separable along the frangible pathway to define a first belt zone and a second belt zone, wherein the first belt zone is laterally between the first side seam and the second belt zone, and wherein the fastener component is adapted to refastenably connect the first belt zone with at least one other component of the absorbent article in a disposal configuration.

15 . The absorbent article of claim 13 , wherein the first belt is a front belt and the second belt is a rear belt.

16 . An absorbent article comprising:
a chassis comprising a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet, the chassis further comprising a first end region and a second end region longitudinally separated from the first end region by a crotch region; a first belt comprising a first end region and a second end region laterally separated from the first end region by a central region, the first end region of the chassis connected with the central region of the first belt, the first belt further comprising a laterally extending inner edge and a laterally extending outer edge, the outer edge positioned longitudinally outward of the inner edge; a second belt comprising a first end region and a second end region laterally separated from the first end region by a central region, the second end region of the chassis connected with the
