Abstract

An absorbent article including a chassis, a pair of opposed elastic side panels attached to the chassis, and at least one fastening tab adhesively attached to each elastic side panel. The at least one fastening tab has a length in the transverse direction of the article and a width in the longitudinal direction of the article and each elastic side panel is embossed on at least a portion thereof, which is adhesively attached to the respective fastening tab, to form at least one embossed groove extending along at least 30%, preferably at least 40% and more preferably at least 60% of the width of the at least one fastening tab.

First claim

The invention claimed is:

1. An absorbent article comprising:
a chassis extending about a longitudinal axis, said chassis having a transverse axis dividing the absorbent article into a first body panel terminating in a first waist region and a second body panel terminating in a second waist region, said chassis being delimited by opposed longitudinal edges and opposed first and second transverse edges;
a pair of opposed elastic side panels attached to said chassis at said second waist region of said second body panel, each of said elastic side panels extending outwardly from each longitudinal edge of the chassis, each of said elastic side panels having a proximal end portion having a proximal edge and a distal end portion having a distal edge, wherein said proximal end portion is attached to the chassis; and
at least one fastening tab attached to said distal end portion of each of said elastic side panels by an adhesive, said at least one fastening tab having a length in the transverse direction of the article and a width in the longitudinal direction of the article,
wherein said distal end portion of each of said elastic side panels includes a plurality of grooves that are substantially parallel to each other and extend in the longitudinal direction of the article along the entire width of the at least one fastening tab, the grooves of each of said elastic side panels being filled with the adhesive, the adhesive forming a body inside the grooves that provides for a bond between the respective side panel and fastening tab.

2. The absorbent article according to claim 1 , wherein said plurality of grooves extend to about 100% of the width of the at least one fastening tab.

3. The absorbent article according to claim 1 , wherein at least one of said elastic side panels is a laminate comprising at least one elastic film and at least one nonwoven layer.

4. The absorbent article according to claim 1 , wherein at least one of said elastic side panels consists of an elastic nonwoven layer.

5. The absorbent article according to claim 1 , wherein said proximal end portion of at least one of said elastic side panels includes the plurality of grooves on at least the portion thereof which is adhesively attached to the chassis, the grooves extending along at least 30% of the width of the proximal edge of the elastic side panel.

6. The absorbent article according to claim 1 , wherein the plurality of grooves have a semi-circular cross-sectional shape.

7. The absorbent article according to claim 1 , wherein the plurality of grooves extend into an area of the elastic side panels that is located adjacent to the fastening tab in the longitudinal direction of the article.

8. The absorbent article according to claim 1 , wherein the plurality of grooves are continuous in the longitudinal direction of the article along the respective elastic side panels.

9. The absorbent article according to claim 1 , wherein the grooves are substantially parallel to said distal edge of the elastic side panel.
