Abstract

Absorbent articles herein may provide a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet. The absorbent core may comprise at least one channel having a shape. The backsheet graphics may substantially match the shape.

Claims

1. An absorbent article comprising:

a central transverse axis and a central longitudinal axis;

a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and an acquisition layer disposed between the topsheet and the absorbent core;

wherein the absorbent core comprises at least one channel that is substantially free of absorbent material;

wherein graphics are printed on the backsheet; and

wherein the at least one channel comprises a shape and the backsheet graphics comprising an inner and an outer portion each comprising a terminating point disposed in a terminating portion of the backsheet graphics and wherein the inner and outer portion collectively substantially match the shape;

wherein the width between the inner and outer portions between their terminating points, is greater than the width between the inner and outer portions at the central transverse axis.

2. The absorbent article of claim 1 further comprising a pair of channels, wherein the channels are mirror images of one another with respect to the central longitudinal axis.

3. The absorbent article of claim 1 wherein the absorbent core further comprises a first supporting sheet and a second supporting sheet, the first supporting sheet and the second supporting sheet being bonded to each other through the at least one channel.

4. The absorbent article of claim 1 further comprising a central longitudinal strip coinciding with the central longitudinal axis, wherein the central longitudinal strip is free of channels.

5. The absorbent article of claim 1 wherein the absorbent core is free of substantially transverse channels in the crotch region.

6. The absorbent article of claim 1 wherein the terminating portion is disposed in the front half of the backsheet.

7. The absorbent article of claim 1 wherein the terminating portion comprises an additional graphic between inner and outer portion.

8. The absorbent article of claim 1 wherein the backsheet graphics further comprise a heart.

9. The absorbent article of claim 1 further comprising an adhesive applied in tapered pattern.

10. The absorbent article of claim 1 wherein the absorbent core comprises a front region, a rear region and a crotch region between the front and rear regions, and wherein the at least one channel is present at least in the crotch region.

11. An absorbent article comprising:

a central transverse axis and a central longitudinal axis;

a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and an acquisition layer disposed between the topsheet and the absorbent core;

wherein the absorbent core comprises at least one channel that comprises adhesive material therein;

wherein graphics are printed on the backsheet; and

wherein the at least one channel comprises a shape and the backsheet graphics comprising an inner and an outer portion each comprising a terminating point disposed in a terminating portion of the backsheet graphics and wherein the inner and outer portion collectively substantially match the shape;

wherein the width between the inner and outer portions between their terminating points, is greater than the width between the inner and outer portions at the central transverse axis.
