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;
a outwardly facing layer; and
a lamination layer positioned between the patient facing layer and the outwardly facing layer,

wherein the lamination layer has a higher loft than the patient facing layer or 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;
a outwardly facing layer; and
a lamination layer positioned between the patient facing layer and the outwardly facing layer,

wherein the lamination layer has a higher loft than the patient facing layer or the outwardly facing layer.

3. The absorbent article of claim 1 , wherein the lamination layer comprises a nonwoven material having a basis weight between 10 and 75 GSM.

4. The absorbent article of claim 1 , wherein the lamination layer comprises a nonwoven material having a basis weight between 45 and 55 GSM.

5. The absorbent article of claim 1 , wherein the patient facing layer, the outwardly facing layer and the lamination layer are bonded at one or more bond sites.

6. The absorbent article of claim 5 , wherein the bond site comprises an ultrasonic bond.

7. The absorbent article of claim 5 , wherein the bond site comprises a thermal bond.

8. The absorbent article of claim 5 , wherein the bond site comprises an adhesive bond.

9. The absorbent article of claim 5 , wherein the one or more bond sites are arranged to form a bonding pattern.

10. The absorbent article of claim 9 , wherein the bonding pattern creates a quilted appearance for at least a portion of the securement portion.

11. The absorbent article of claim 1 , the patient facing layer having a width in a lateral direction extending parallel to the width of the securement portion and a length extending longitudinally parallel to the length of the securement portion; and the lamination layer having a width in a lateral direction extending parallel to the width of the securement portion and a length extending longitudinally parallel to the length of the securement portion,
wherein, the width of the lamination layer is less than the width of the patient facing layer.

12. The absorbent article of claim 11 , wherein the length of the lamination layer is less than the length of the patient facing layer.

13. 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 lamination layer positioned between the patient facing layer and the outwardly facing layer, the lamination layer comprising:
an absorbent material; and
a skin care solution absorbed into the absorbent material.

14. The absorbent article of claim 13 , wherein the skin care solution comprises a lotion.

15. The absorbent article of claim 13 , wherein the patient facing layer comprises a porous material configured such that the skin care solution transfers from the lamination layer through the patient facing layer to the skin of a user of the absorbent article.

16. The absorbent article of claim 15 , wherein the lamination layer comprises a nonwoven material.

17. The absorbent article of claim 15 , wherein the lamination layer comprises a foam material.

18. 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;
a outwardly facing layer; and
a lamination layer positioned between the patient facing layer and the outwardly facing layer, the lamination layer comprising:
an absorbent material having a higher loft than the patient facing layer or the outwardly facing layer; and
a skin care solution absorbed into the absorbent material.

19. The absorbent article of claim 18 , wherein the patient facing layer, the outwardly facing layer and the lamination layer are bonded at one or more bond sites.

20. The absorbent article of claim 19 , the patient facing layer having a perimeter;
the outwardly facing layer having a perimeter; and
the lamination layer having a perimeter,
wherein the lamination layer perimeter is smaller than the patient facing layer perimeter and the outwardly facing layer perimeter, such that the securement portion comprises a first portion having the patient facing layer, the outwardly facing layer, and the lamination layer and a second portion having the patient facing layer and the outwardly facing layer without the lamination layer.

21. The absorbent article of claim 20 , wherein at least one of the one or more bond sites is positioned on the first portion having the patient facing layer, the outwardly facing layer, and the lamination layer.

22. The absorbent article of claim 18 , wherein at least one of the one or more bond sites is positioned on the second portion having the patient facing layer and the outwardly facing layer without the lamination layer.

23. 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 th
