Abstract

An article including a front region, a back region, and a chassis. The chassis may include an absorbent core having a front end edge and a back end edge. The front region and the back region may extend laterally outward beyond side edges of the chassis. The front region and the back region may abut to form a first seam and a second seam. At least one of the front region and the back region may include an elastic member. A first outer nonwoven layer of the front region and a second outer nonwoven layer of the back region may be folded to form an upper edge in the front and back regions such that a distal end of each of the first and second outer nonwoven layer may be disposed between the upper edge and the front and back end edges of the absorbent core, respectively.

First claim

What is claimed is:

1. A pull-on wearable article comprising:
a front region;
a back region opposite the front region;
a first central longitudinal axis extending parallel to a vertical plane equally bisecting the front region;
a second central longitudinal axis extending parallel to a vertical plane equally bisecting the back region;
a crotch region disposed between the front region and the back region, wherein the crotch region comprises two opposing longitudinal edges;
a chassis comprising an absorbent core extending from the front region to the back region, the absorbent core comprising a front end edge and a back end edge;
wherein the front region extends laterally outward beyond side edges of the chassis and the back region extends laterally outward beyond side edges of the chassis;
wherein the front region comprises a first front edge and a second front edge, wherein the first front edge extends in a direction parallel to the first central longitudinal axis, and wherein the second front edge extends in a direction parallel to the first central longitudinal axis;
wherein the back region comprises a first back edge and a second back edge, wherein the first back edge extends in a direction parallel to the second central longitudinal axis, and wherein the second back edge extends in a direction parallel to the second central longitudinal axis;
wherein a portion of the front region including the first front edge and a portion of the back region including the first back edge abut to form a first seam;
wherein a portion of the front region including the second front edge and a portion of the back region including the second back edge abut to form a second seam;
wherein the front region and the back region are configured to form a continuous belt, a first leg opening, and a second leg opening;
wherein at least one of the front region and the back region comprises an elastic member, wherein the elastic member comprises a film having one or more apertures; and
a folded continuous belt portion comprising a fold line and including at least a first outer nonwoven layer of the front region and at least a second outer nonwoven layer of the back region, wherein the folded continuous belt portion extends about a circumference of the continuous belt when positioned on the wearer, and wherein the folded continuous belt portion comprises an upper edge coinciding with the fold line in the front and back regions such that a distal end of each of the first and second outer nonwoven layers is disposed between the upper edge and the front and back end edges of the absorbent core, respectively;
wherein the folded continuous belt portion comprises a first portion disposed in the front region and extending in a lateral direction between the first seam and the second seam and extending in a longitudinal direction between the upper edge and the distal end of the nonwoven outer layer, wherein the first portion has a first longitudinal distance measured from the upper edge to the distal end of the nonwoven outer layer;
wherein the folded continuous belt portion comprises a second portion disposed in the back region and extending in a lateral direction between the first seam and the second seam and extending in the longitudinal direction between the upper edge and the distal end of the nonwoven outer layer, wherein the second portion has a second longitudinal distance measured from the upper edge to the distal end of the nonwoven outer layer;
wherein the first longitudinal distance is substantially the same as the second longitudinal distance;
wherein the first seam comprises a pattern of discrete spaced bonds extending continuously in the longitudinal direction from the first leg opening to the upper edge; and
wherein the second seam comprises a pattern of discrete spaced bonds extending continuously in the longitudinal direction from the second leg opening to the upper edge.

2. The pull-on wearable article of claim 1 , further comprising a graphic disposed on a wearer facing surface of the wearable absorbent article.

3. The pull-on wearable article of claim 1 , further comprising a gasketing leg cuff disposed in a crotch region, wherein the gasketing leg cuff includes one or more elastic strands.

4. The pull-on wearable article of claim 1 , wherein at least one of the first outer nonwoven layer and the second outer nonwoven layer is joined to a liquid impervious film to form a backsheet.

5. The pull-on wearable article of claim 4 , wherein a portion of the backsheet is joined with a topsheet.

6. The pull-on wearable article of claim 1 , wherein the elastic member is disposed on at least one of the first outer nonwoven layer and the second outer nonwoven layer.

7. The pull-on wearable article of claim 1 , wherein the elastic member is a continuous planar layer.

8. The pull-on wearable article of claim 1 , further comprising a first gap between the absorbent core and the upper edge such that the front end edge of the absorbent core does not overlap the distal end of the first outer nonwoven layer.

9. The pull-on wearable article of claim 1 , further comprising a second gap between the absorbent core and the upper edge such that the back end edge of the absorbent core does not overlap the distal end of the second outer nonwoven layer.

10. The pull-on wearable article of claim 1 , wherein the first seam and the second seam each include a first portion having a first thickness and a second portion having a second thickness, wherein the first thickness is greater than the second thickness.

11. The pull-on wearable article of claim 1 , wherein the distal end of each of the first and second nonwoven layers is disposed on a wearer facing surface of the article.

12. The pull-on wearable article of claim 1 , wherein the distal end of each of the first and second nonwoven layers is disposed on a garment facing surface of the article.

13. A pull-on wearable article comprising:
a front region;
a back region opposite the front region;
a longitudinal axis extending in a vertical direction and equally bisecting at least one of the front region and the back region;
a crotch region disposed between the front region and the back region;
a chassis comprising an absorbent core extending from the front region to the back region, the absorbent core comprising a front end edge and a back end edge;
wherein the front region extends laterally outward beyond side edges of the chassis and the back region extends laterally outward beyond side edges of the chassis;
wherein the front region comprises a first front edge and a second front edge and the back region comprises a first back edge and a second back edge, and wherein each of the first front edge, the second front edge, the first back edge, and the second back edge extend in a longitudinal direction parallel to the longitudinal axis;
wherein a portion of the front region and a portion of the back region abut to form a first seam and a second seam such that the front region and the back region are configured to form a continuous belt, a first leg opening, and a second leg opening;
wherein at least one of the front region and the back region comprises an elastic member, wherein the elastic member comprises a film having one or more apertures;
a folded continuous belt portion comprising a fold line and including at least a first outer nonwoven layer of the front region and at least a second outer nonwoven layer of the back region, wherein the folded continuous belt portion extends about a circumference of the continuous belt when positioned on the wearer, and wherein the folded continuous belt comprises an upper edge in the front and
