Abstract

An absorbent article is provided. The absorbent article includes an absorbent assembly having a liquid permeable inner layer, an outer layer, and an absorbent body between the inner and outer layers. A pair of ears extend transversely outward from opposite sides of the absorbent assembly in a back waist region, each of the ears having a primary first fastening-component that is selectively engagable with a primary second fastening-component in a front waist region. There is a pair of spaced-apart secondary first fastening-components disposed on the outer layer in the front waist region, each of the secondary first fastening-components being selectively engageable with the secondary second fastening-components. Each secondary first fastening-component fits into a fastener region, wherein each fastener region is defined by an outline. Each outline has a waist edge and an opposite leg edge connected by an outer edge and an inner edge. The length of the outer edge is shorter than the length of the inner edge.

First claim

What is claimed is:

1. An absorbent article comprising:
an absorbent assembly including longitudinally opposite ends, transversely opposite sides, a front waist region, a back waist region, and a crotch region extending longitudinally between and interconnecting the front and back waist regions, a liquid permeable inner layer for facing a wearer, an outer layer for facing away from the wearer, an absorbent body disposed between the inner and outer layers, at least one of the inner layer and outer layer defining the longitudinally opposite ends and transversely opposite sides of the absorbent assembly, the absorbent body having a pair of longitudinally extending sides and a pair of transversely extending ends, each of the longitudinally extending sides of the absorbent body being spaced inward from a respective one of the transversely opposite sides of the absorbent assembly;
a pair of ears extending transversely outward from the opposite sides of the absorbent assembly in the back waist region, each of the ears comprising a primary first fastening-component that is selectively engagable with a primary second fastening-component in the front waist region of the absorbent assembly in a wear configuration of the article; and
a pair of spaced-apart secondary first fastening-components disposed on the primary second fastening-component in the front waist region of the absorbent assembly, each of the secondary first fastening-components being selectively engageable with respective secondary second fastening-components in a wear configuration of the article;
wherein the secondary first fastening-components fit into respective fastener regions, each fastener region defined by an outline surrounding the secondary first-fastening components, wherein each outline has a waist edge and an opposite leg edge connected by an outer edge and an inner edge;
wherein the waist edge of each outline is spaced from a waist edge of the primary second fastening-component;
wherein the length of the outer edge is shorter than the length of the inner edge; and
wherein the primary first fastening-components do not overlap the secondary first-fastening components in a wear configuration of the article.

2. The absorbent article of claim 1 wherein the secondary first-fastening components are discontinuous.

3. The absorbent article of claim 2 wherein the secondary-first fastening components comprise a plurality of islands, wherein each island has an area.

4. The absorbent article of claim 3 wherein the waist edge is bisected by a normal axis line, and the sum of the island areas between the outer edge and the axis line is less than the sum of the island areas between the inner edge and the axis line.

5. The absorbent article of claim 4 wherein the plurality of islands comprises two islands in a side-by-side configuration with respect to the waist edge.

6. The absorbent article of claim 4 wherein the plurality of islands comprises two islands in a stacked configuration with respect to the waist edge.

7. The absorbent article of claim 1 wherein there is an obtuse angle formed by the outer edge and the leg edge.

8. The absorbent article of claim 7 wherein the obtuse angle is between 100 degrees and 150 degrees.

9. An absorbent article comprising:
an absorbent assembly including longitudinally opposite ends, transversely opposite sides, a front waist region, a back waist region, and a crotch region extending longitudinally between and interconnecting the front and back waist regions, a liquid permeable inner layer for facing a wearer, an outer layer for facing away from the wearer, an absorbent body disposed between the inner and outer layers, at least one of the inner layer and outer layer defining the longitudinally opposite ends and transversely opposite sides of the absorbent assembly, the absorbent body having a pair of longitudinally extending sides and a pair of transversely extending ends, each of the longitudinally extending sides of the absorbent body being spaced inward from a respective one of the transversely opposite sides of the absorbent assembly;
a pair of ears extending transversely outward from the opposite sides of the absorbent assembly in the back waist region, each of the ears comprising a primary first fastening-component that is selectively engagable with a primary second fastening-component in the front waist region of the absorbent assembly in a wear configuration of the article; and
a pair of spaced-apart secondary first fastening-components disposed on the primary second fastening-component in the front waist region of the absorbent assembly, each of the secondary first fastening-components being selectively engageable with respective secondary second fastening-components in a wear configuration of the article;
wherein the secondary first fastening-components comprise continuous areas of secondary first fastening-material defining at least two discrete islands, a waist-region discrete island having a first area, and a leg-region discrete island having a second area,
wherein the first area is larger than the second area;
wherein the primary first fastening-components do not overlap the secondary first-fastening components in a wear configuration of the article.

10. The absorbent article of claim 9 further comprising a middle discrete island having a third area located between the waist-region discrete island, and the leg-region discrete island, wherein the second area is smaller than the third area.

11. The absorbent article of claim 9 wherein the second area has a triangular shape.

12. The absorbent article of claim 11 wherein the outermost angle of the second area is an acute angle.

13. The absorbent article of claim 11 wherein the outermost angle of the second area is between 15 degrees and 60 degrees.

14. The absorbent article of claim 11 wherein the outermost angle of the second area is between 20 degrees and 45 degrees.

15. An absorbent article comprising:
an absorbent assembly including longitudinally opposite ends, transversely opposite sides, a front waist region, a back waist region, and a crotch region extending longitudinally between and interconnecting the front and back waist regions, a liquid permeable inner layer for facing a wearer, an outer layer for facing away from the wearer, an absorbent body disposed between the inner and outer layers, at least one of the inner layer and outer layer defining the longitudinally opposite ends and transversely opposite sides of the absorbent assembly, the absorbent body having a pair of longitudinally extending sides and a pair of transversely extending ends, each of the longitudinally extending sides of the absorbent body being spaced inward from a respective one of the transversely opposite sides of the absorbent assembly;
a pair of ears extending transversely outward from the opposite sides of the absorbent assembly in the back waist region, each of the ears comprising a primary first fastening-component that is selectively engagable with a primary second fastening-component in the front waist region of the absorbent assembly in a wear configuration of the article; and
a pair of spaced-apart secondary first fastening-components disposed on the primary second fastening-component in the front waist region of the absorbent assembly, each of the secondary first fastening-components being selectively engageable with respective secondary second fastening-components in a wear configuration of the article;
wherein the secondary first fastening-components are defined by rows of islands disposed within a rectangular region having a waist edge and an opposite leg edg
