Abstract

An absorbent article includes a chassis having a substantially rectangular shape a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids. The absorbent article includes a first securement portion operatively coupled to the first portion of the chassis. The absorbent article includes a second securement portion operatively coupled to the second portion of the chassis and configured to releasably attach to the first securement portion. The chassis is configured to include one of a first chassis length or a second chassis length. When the chassis includes the first length, the chassis includes a first width and the first securement portion includes a second width, and when the chassis includes the second length, the chassis includes the first width and the first securement portion includes a third width, greater than the second width.

First claim

What is claimed is:

1. An absorbent article, comprising:
a chassis, the chassis including a length extending in a longitudinal direction from the back to the front of a user and a width extending in a lateral direction substantially perpendicular to the length between first and second longitudinal edges, the chassis comprising a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids;
a securement portion operatively coupled to the first portion of the chassis, the securement portion having a width extending in a lateral direction from the first longitudinal edge of the chassis first portion and a length extending longitudinally along the first longitudinal edge, the securement portion comprising:
a patient facing layer;
an outwardly facing layer; and
a non-elastic lamination layer positioned between the patient facing layer and the outwardly facing layer.

2. The absorbent article of claim 1 , further including:
a second securement portion operatively coupled to the second portion of the chassis in a position longitudinally spaced from the first securement portion and configured to releasably attach to the first securement portion, the second securement portion comprising:
a patient facing layer;
an outwardly facing layer; and
a non-elastic lamination layer positioned between the patient facing layer and the outwardly facing layer.

3. The absorbent article of claim 1 , wherein the lamination layer has a higher loft than the patient facing layer or the outwardly facing layer.

4. The absorbent article of claim 1 , wherein the patient facing layer is softer than the lamination layer.

5. The absorbent article of claim 1 , wherein the patient facing layer is more flexible than the lamination layer.

6. The absorbent article of claim 1 , wherein the lamination layer has a perimeter that is smaller than a perimeter of the outwardly facing layer.

7. The absorbent article of claim 1 , wherein the lamination layer has a perimeter that is smaller than a perimeter of the patient facing layer.

8. The absorbent article of claim 7 , wherein a portion of the securement portion without a lamination layer completely surrounds the lamination layer.

9. The absorbent article of claim 1 , wherein the lamination layer extents from a securement portion top edge to a securement portion bottom edge such that a first portion without a lamination layer is formed adjacent the chassis.

10. The absorbent article of claim 9 , wherein a second portion without a lamination layer is formed adjacent the distal edge of the securement portion.

11. The absorbent article of claim 1 , wherein the lamination layer comprises alternating strips of non-elastic lamination layer.

12. The absorbent article of claim 11 , wherein the alternating strips of lamination layer extend from a securement portion top edge to a securement portion bottom edge.

13. The absorbent article of claim 11 , wherein the alternating strips of lamination layer extend only part of the distance from a securement portion top edge to a securement portion bottom edge.

14. An absorbent article, comprising:
a chassis, the chassis including a length extending in a longitudinal direction from the back to the front of a user and a width extending in a lateral direction substantially perpendicular to the length between first and second longitudinal edges, the chassis comprising a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids;
a securement portion operatively coupled to the first portion of the chassis, the securement portion having a width extending in a lateral direction from the first longitudinal edge of the chassis first portion and a length extending longitudinally along the first longitudinal edge, the securement portion comprising:
a first facing layer;
a second facing layer; and
a non-elastic lamination layer positioned between the first facing layer and the second facing layer.

15. The absorbent article of claim 14 , wherein the first facing layer has a first loft, and the lamination layer has a second loft different from the first loft.

16. The absorbent article of claim 14 , wherein the securement portion further comprises an extension portion that extends beyond the first facing layer and second facing layer in the lateral direction.

17. The absorbent article of claim 16 , wherein the extension portion comprises an elastic panel.

18. The absorbent article of claim 14 , wherein the lamination layer is bonded to the first facing layer and the second facing layer.

19. The absorbent article of claim 18 , wherein the lamination layer is bonded to the first facing layer and the second facing layer at least in part by a bond selected from a group bonds consisting of glue, a heat bond, a pressure bond, a heat and pressure bond, and an ultrasonic bond.

20. The absorbent article of claim 18 , wherein the lamination layer is bonded to the first facing layer and the second facing layer in a bonding pattern.
