Abstract

A disposable wearable absorbent article comprising an absorbent core area, a side, and an anchoring subsystem. The anchoring subsystem includes exactly one side anchoring member. The side anchoring member has a pathway with a front end, a back end, and a middle. The front end, the back end, or both ends are disposed outside of the absorbent core area. The front end is disposed at a front end longitudinally outboard distance. The back end is disposed at a back end longitudinally outboard distance. The middle is disposed at a middle longitudinally outboard distance. The front end longitudinally outboard distance is less than the back end longitudinally outboard distance. The back end longitudinally outboard distance is about equal to the middle longitudinally outboard distance.

Claims (68)

1. A disposable wearable fastenable absorbent article having a lateral centerline, that when in an unfastened state comprises:

an absorbent core area;

a side, comprising a front portion and a back portion; and

an anchoring subsystem contained within a particular, defined area of the disposable wearable absorbent article, said defined area being the side; where said anchoring subsystem includes exactly one side anchoring member, wherein the entire side anchoring member is embedded, partly in the front portion of the side and partly in the back portion of the side;

wherein when the article is in an unfastened state, no part of the side anchoring member crosses the lateral centerline;

and wherein the side anchoring member includes:

a pathway;

a front end of the pathway disposed at a front end location at a front end longitudinally outboard distance;

a back end of the pathway disposed at a back end location at a back end longitudinally outboard distance; and

a middle disposed along the pathway between the front end and the back end, including a middle location disposed at a middle longitudinally outboard distance;

wherein:

at least one of the front end location and the back end location is outside of the absorbent core area;

the front end longitudinally outboard distance is less than the back end longitudinally outboard distance; and

the back end longitudinally outboard distance is about equal to the middle longitudinally outboard distance;

and wherein the side anchoring member does not substantially encircle a leg of a wearer when the article is worn by the wearer.

2. The disposable wearable absorbent article of claim 1 , wherein the side includes the anchoring subsystem, which is a side anchoring subsystem.

3. The disposable wearable absorbent article of claim 1 , wherein:

the article is a pant-type article;

the article includes a front;

the side is a side panel, with a front portion in the front, wherein the front portion includes a laterally inboard edge; and

the front end location is proximate to the laterally inboard edge.

4. The disposable wearable absorbent article of claim 1 , wherein:

the article is a pant-type article;

the article includes a back;

the side is a side panel, with a back portion in the back, wherein the back portion includes a laterally inboard edge; and

the back end location is proximate to the laterally inboard edge.

5. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a side ear panel, which includes the side anchoring member and a fastener; and

the front end location is proximate to the fastener.

6. The fastenable disposable wearable absorbent article of claim 5 , wherein:

the fastener is a first fastener; and

the side ear includes a second fastener, longitudinally outboard from the first fastener.

7. The fastenable disposable wearable absorbent article of claim 6 , wherein the first fastener is an active fastener.

8. The fastenable disposable wearable absorbent article of claim 6 , wherein the first fastener is a passive fastener.

9. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a first portion and a second portion, outside of the first portion;

substantially all of the side anchoring member is disposed within the first portion;

substantially all of the first portion is configured to have a higher directional modulus of elasticity; and

substantially all of the second portion is configured to have one or more lower directional moduli of elasticity.

10. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a first portion and a second portion, outside of the first portion;

substantially all of the side anchoring member is disposed within the first portion;

substantially all of the first portion is incrementally stretched to a lesser degree; and

substantially all of the second portion is incrementally stretched to one or more greater degrees.

11. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a first portion and a second portion, outside of the first portion;

substantially all of the side anchoring member is disposed within the first portion;

one or more unstretched areas are distributed throughout substantially all of the first portion; and

substantially all of the second portion is incrementally stretched.

12. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a first portion and a second portion, outside of the first portion;

substantially all of the side anchoring member is disposed within the first portion; and

one or more over-bonded areas are distributed throughout substantially all of the first portion.

13. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a first portion and a second portion, outside of the first portion;

substantially all of the side anchoring member is disposed within the first portion;

substantially all of the first portion includes a higher caliper elastomer; and

substantially all of the second portion includes one or more lower caliper elastomers.

14. The disposable wearable absorbent article of claim 1 , wherein:

the side includes a first portion and a second portion, outside of the first portion;

substantially all of the side anchoring member is disposed within the first portion;

substantially all of the first portion includes a higher performance elastomer; and

substantially all of the second portion includes one or more lower performance elastomers.

15. The disposable wearable absorbent article of claim 1 , wherein:

the side anchoring member has an overall length; and

the side anchoring member has a substantially uniform width over the entire overall length.

16. The disposable wearable absorbent article of claim 1 , wherein an overall shape of a portion of the pathway between the middle and the front end is curved.

17. The disposable wearable absorbent article of claim 1 , wherein the side anchoring member is configured as a geodesic.
