Abstract

An array of disposable absorbent articles is described herein. The array has a first plurality of absorbent articles and a second plurality of absorbent articles. Each of the first plurality and second plurality of absorbent articles have absorbent cores having patterned end edges each having a plurality of inflection points.

First claim

What is claimed is:

1. A package of disposable absorbent articles, the package comprising:
a first plurality of absorbent articles and a second plurality of absorbent articles, each of the first plurality of absorbent articles and the second plurality of absorbent articles comprising a topsheet; a backsheet; and an absorbent core disposed between the topsheet and the backsheet, wherein, each absorbent core has a first longitudinal side edge and a second longitudinal side edge, a first end edge connecting the first longitudinal side edge and the second longitudinal side edge on one end of the absorbent core, a second end edge connecting the first longitudinal side edge and the second longitudinal side edge on an opposing second end of the absorbent core, wherein each of the first end edge and the second end edge comprise a first patterned portion, a second patterned portion, and a connecting portion, wherein each of the first patterned portion and second pattern portion comprise a plurality of inflection points disposed inboard of the first longitudinal side edge and the second longitudinal side edge, as determined via a k-curvature analysis test method, wherein a first portion of absorbent cores is associated with the first plurality of absorbent articles and wherein each of the absorbent cores of the first portion has a first length and a second portion of absorbent cores is associated with the second plurality of absorbent articles and wherein each of the absorbent cores of the second portion has a second length, and wherein the first length and second length are different.

2. The package of absorbent articles of claim 1 , wherein first patterned portion and second patterned portion of the first end edge comprises a first number of inflection points, wherein the first patterned portion and second patterned portion of the second end edge comprises a second number of inflection point, wherein the first number and the second number are equal.

3. The package of absorbent articles of claim 1 , wherein first patterned portion and second patterned portion of the first end edge comprises a first number of inflection points, wherein the first patterned portion and second patterned portion of the second end edge comprises a second number of inflection point, wherein the first number is greater than the second number.

4. The package of absorbent articles of claim 1 , wherein first patterned portion and second patterned portion of the first end edge comprises a first number of inflection points, wherein the first patterned portion and second patterned portion of the second end edge comprises a second number of inflection point, wherein the first number is less than the second number.

5. The package of absorbent articles of claim 1 , wherein each of the absorbent cores comprises a first pattern distance corresponding to the first end edge and a second pattern distance corresponding to the second end edge, wherein the first pattern distance is equal to the second pattern distance.

6. The package of absorbent articles of claim 1 , wherein each of the absorbent cores comprises a first pattern distance corresponding to the first end edge and a second pattern distance corresponding to the second end edge, wherein the first pattern distance is greater than the second pattern distance.

7. The package of absorbent articles of claim 1 , wherein each of the absorbent cores comprises a first pattern distance corresponding to the first end edge and a second pattern distance corresponding to the second end edge, wherein the first pattern distance is less than the second pattern distance.

8. The package of absorbent articles of claim 1 , wherein the first end width is between 50 percent to 90 percent of the second end width.

9. The package of absorbent articles of claim 1 , wherein each of the absorbent cores have a first width associated with the first end of the absorbent core and a second width associated with the second end of the absorbent core, wherein the first width is less than the second width.

10. The package of absorbent articles of claim 9 , wherein the second end width is about 76 mm.

11. The package of absorbent articles of claim 9 wherein the first end width is about 56 mm.

12. The package of absorbent articles of claim 1 , wherein the first plurality of plurality of absorbent articles are in a second package and designated as absorbent articles are disposed in a first package and designated as a first size and the second a second size, and wherein the first size and the second size are the same.

13. The package of absorbent articles of claim 1 , wherein the first end width is between 63 percent to 83 percent of the second end width.

14. The package of absorbent articles of claim 1 , wherein the first end width is between 70 percent to 75 percent of the second end width.
