Absorbent article having elastomeric panels
A garment-like absorbent article can have a front region, a back region, and a central region extending between and connecting the front region and the back region. The front region and the back region of the absorbent article can be formed from a combination of elastic materials. The combination of the elastic materials can be asymmetrically configured about the absorbent article to provide an improved fit of the absorbent article to the body of the wearer as well as to provide the wearer with an absorbent article that resembles traditional woven underwear.
1 . An absorbent article comprising:
a. a front region comprising a front panel comprising:
i. a front panel upper edge, a front panel lower edge, a first front side edge, and a second front side edge;
ii. a first longitudinal length between the front panel upper edge and the front panel lower edge;
iii. a first elastomeric panel comprising a first elastomeric panel material selected from an elastomeric film, an elastomeric nonwoven web or a laminate of at least one elastomeric polymeric film layer and at least one nonwoven web layer;
iv. a first laminate comprising elastomeric strands and a nonwoven layer and defining a front waist portion having a front waist portion longitudinal length and a front central chassis portion having a front central chassis portion longitudinal length, wherein the first laminate is disposed between the first elastomeric panel and the front panel upper edge;
b. a back region comprising a back panel comprising:
i. a back panel upper edge, a back panel lower edge, a first back side edge, and a second back side edge;
ii. a second longitudinal length between the back panel upper edge and the back panel lower edge;
iii. a second elastomeric panel comprising a second elastomeric panel material selected from an elastomeric film, an elastomeric nonwoven web or a laminate of at least one elastomeric polymeric film layer and at least one nonwoven web layer;
iv. a second laminate comprising elastomeric strands and a nonwoven layer and defining a back waist portion having a back waist portion longitudinal length and a back central chassis portion having a back central chassis portion longitudinal length, wherein the back central chassis portion longitudinal length is greater than the front central chassis portion longitudinal length, wherein the second laminate is disposed between the second elastomeric panel and the back panel upper edge;
c. a central region extending between the front region and the back region and comprising an absorbent assembly; and
d. wherein the front panel and the back panel have an asymmetrical configuration with respect to each other with the first elastomeric panel having a longitudinal length that is greater than a longitudinal length of the second elastomeric panel, and
e. wherein a front panel material forming the front panel and a back panel material forming the back panel have different tension strains.
2 . The absorbent article of claim 1 wherein the front waist portion longitudinal length is the same as the back waist portion longitudinal length.
3 . The absorbent article of claim 1 wherein the longitudinal length of the first elastomeric panel is from 60% to 66% of the first longitudinal length of the front panel.
4 . The absorbent article of claim 3 wherein the longitudinal length of the second elastomeric panel is from 53% to 59% of the second longitudinal length of the back panel.
5 . The absorbent article of claim 1 wherein the front central chassis portion longitudinal length is from 15% to 25% of the first longitudinal length of the front panel.
6 . The absorbent article of claim 1 wherein the back central chassis portion longitudinal length is from 26% to 36% of the second longitudinal length of the back panel.
7 . The absorbent article of claim 1 wherein the front waist portion comprises multiple elastomeric strands which are parallel to each other and uniformly spaced from each other.
8 . The absorbent article of claim 7 wherein the spacing between each of the elastomeric strands of the front waist portion is less than 5 mm.
9 . The absorbent article of claim 1 wherein the front central chassis portion comprises multiple elastomeric strands which are parallel to teach other and uniformly spaced from each other.
10 . The absorbent article of claim 9 wherein the spacing between each of the elastomeric strands of the front central chassis portion is at least 5 mm.
11 . The absorbent article of claim 1 wherein the front waist portion and the back waist portion combine to form a waist region and wherein the front first elastomeric panel and the second elastomeric panel combine to form an elastomeric panel region and a load at 50% strain of the waist region is greater than or equal to a load at 50% strain of the elastomeric panel region.
12 . The absorbent article of claim 11 wherein the front central chassis portion and the back central chassis portion combine to form a central chassis region and a load at 50% strain of the central chassis region is less than the load at 50% strain of the waist region and the elastomeric panel region.
13 . The absorbent article of claim 1 , wherein the absorbent assembly overlaps the first elastomeric panel and the second elastomeric panel and does not overlap the first laminate or the second laminate.
