Abstract

An absorbent article can have an improved attachment to a wearer's undergarment and can maintain proper placement in the undergarment of the wearer. The absorbent article can produce less waste for the wearer of the absorbent article. The absorbent article can have a topsheet layer, a backsheet layer, an absorbent core positioned between the topsheet layer and the backsheet layer, and a pair of opposing wings. The absorbent article can have a mechanical garment attachment which can maintain the placement of the absorbent article within the wearer's undergarment.

First claim

What is claimed is:

1. An absorbent article comprising:
a. a longitudinal axis and a transverse axis;
b. an anterior portion, a posterior portion, and a central portion extending between the anterior portion and the posterior portion;
c. a topsheet layer, a backsheet layer, and an absorbent core positioned between the topsheet layer and the backsheet layer;
d. a first wing extending in a first transverse direction and a second wing extending in a second transverse direction which is opposite the first transverse direction;
e. a pair of opposing primary garment attachment regions, each of the primary garment attachment regions having a first segment positioned in a chassis area of the absorbent article, a second segment positioned in a wing folding area of the absorbent article, and a third segment positioned in a wing area of the absorbent article; and
f. a mechanical garment attachment positioned within each of the primary garment attachment regions.

2. The absorbent article of claim 1 wherein each primary garment attachment region has a primary garment attachment region angle relative to the longitudinal axis from about 15 degrees to about 70 degrees.

3. The absorbent article of claim 1 wherein each primary garment attachment region has a width from about 2 mm to about 15 mm.

4. The absorbent article of claim 1 wherein each primary garment attachment region has a length from about 20 mm to about 90 mm.

5. The absorbent article of claim 1 further comprising a second pair of opposing primary garment attachment regions.

6. The absorbent article of claim 1 further comprising a pair of opposing secondary garment attachment regions.

7. The absorbent article of claim 6 wherein the pair of opposing secondary garment attachment regions are positioned in the anterior portion of the absorbent article.

8. The absorbent article of claim 6 wherein the pair of opposing secondary garment attachment regions are positioned in the posterior portion of the absorbent article.

9. The absorbent article of claim 6 wherein each of the secondary garment attachment regions has a secondary garment attachment region angle relative to the longitudinal axis from about 15 degrees to about 70 degrees.

10. The absorbent article of claim 6 wherein each of the secondary garment attachment regions has a width from about 2 mm to about 15 mm.

11. The absorbent article of claim 6 wherein each of the secondary garment attachment regions has a length from about 15 mm to about 50 mm.

12. The absorbent article of claim 1 wherein the second segment of each of the primary garment attachment regions comprises a plurality of mechanical garment attachments positioned therein wherein the mechanical garment attachments are positioned in a plurality of rows of the mechanical garment attachments and a first row of plurality of rows of the mechanical garment attachments is in a spaced apart configuration from a second row of the plurality of rows of the mechanical garment attachments.

13. The absorbent article of claim 1 wherein the mechanical garment attachment is bonded directly to a base substrate wherein the base substrate is bonded directly to the backsheet layer of the absorbent article.

14. The absorbent article of claim 13 wherein a score line is incorporated into the base substrate.
