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. A system of absorbent articles comprising a first absorbent article and a second absorbent article, each absorbent article of the system 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 first securement portion operatively coupled to the first portion of the chassis, the first securement portion having a width extending in a lateral direction from the first longitudinal edge of the first portion of the chassis and a length extending longitudinally along the first longitudinal edge; and
a second securement portion having a stretch portion and a non-stretch portion, the 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;
wherein for the first absorbent article, the chassis length is a first length, the stretch portion of the second securement portion has a first width and the non-stretch portion of the second securement portion has a second width; and
wherein for the second absorbent article, the chassis length is a second length different from the first length, the stretch portion of the second securement portion has the first width and the non-stretch portion of the second securement portion has a third width greater than the second width.

2. The system of absorbent articles of claim 1 , wherein the portion of the chassis being configured to absorb fluids includes a core have an embossed top side and an embossed bottom side.

3. The system of absorbent articles of claim 1 , wherein the stretch portion and the non-stretch portion are operatively coupled at a seam, a portion of the second securement portion configured to overlap a portion of the first securement portion such that the seam is disposed on the first securement portion.

4. The system of absorbent articles of claim 1 , wherein the non-stretch portion of the second securement portion is a first non-stretch portion, and the stretch portion is disposed between the first non-stretch portion and a second non-stretch portion of the of the second securement portion.

5. The system of absorbent articles of claim 4 , wherein the stretch portion and the first non-stretch portion are operatively coupled at a first seam, the stretch portion and the second non-stretch portion being operatively coupled at a second seam, a portion of the second securement portion configured to overlap a portion of the first securement portion such that the first seam is disposed on the first securement portion.

6. The system of absorbent articles of claim 5 , wherein a portion of the second securement portion is configured to overlap a portion of the first securement portion such that the first seam and the second seam are disposed on the first securement portion.

7. The system of absorbent articles of claim 1 , wherein the first absorbent article is configured to fit a first range of users, and the second absorbent article is configured to fit a second range of users, different from the first range of users.

8. The system of absorbent articles of claim 7 , wherein the first range of users is mutually exclusive from the second range of users.

9. A system of absorbent articles, each absorbent article of the system 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 first securement portion operatively coupled to the first portion of the chassis, the first securement portion having a width extending in a lateral direction from the first longitudinal edge of the first portion of the chassis and a length extending longitudinally along the first longitudinal edge; and
a second securement portion having a stretch portion and a non-stretch portion, the 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;
wherein the width of the non-stretch portion of the second securement portion is proportional to the length of the chassis, and width of the stretch portion of the second securement portion is not proportional to the length of the chassis.

10. The system of absorbent articles of claim 9 wherein, the chassis is configured to include one of a first length or a second length and when the chassis includes the first length, the stretch portion of the second securement portion includes a first width and the non-stretch portion of the second securement portion includes a second width.

11. The system of absorbent articles of claim 10 wherein, when the chassis includes the second length, the stretch portion of the second securement portion includes the first width and the non-stretch portion of the second securement portion includes a third width, greater than the second width.

12. The system of absorbent articles of claim 9 wherein the non-stretch portion of the second securement portion comprises a first non-stretch panel and a second non-stretch panel.

13. The system of absorbent articles of claim 12 wherein the stretch portion is positioned between the first non-stretch panel and the second non-stretch panel.

14. The system of absorbent articles of claim 12 wherein:
a proximal edge of the first non-stretch panel overlaps the first chassis longitudinal edge and is coupled to the chassis;
a proximal edge of the stretch portion overlaps a distal edge of the first non-stretch panel and is coupled to the first non-stretch panel; and
a proximal edge of the second non-stretch panel overlaps a distal edge of the stretch portion and is coupled to the stretch portion.

15. The system of absorbent articles of claim 14 further comprising a fastener coupled to the second non-stretch panel.

16. The system of absorbent articles of claim 15 wherein the fastener overlaps with and extends beyond a distal edge of the second non-stretch panel.

17. The system of absorbent articles of claim 15 wherein the fastener is positioned within a periphery of the second non-stretch panel and does not extend beyond a distal edge of the second non-stretch panel.

18. The system of absorbent articles of claim 17 wherein the fastener is spaced apart from the distal edge of the second non-stretch panel.

19. A system of absorbent articles, each absorbent article of the system 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, and
