Abstract

A disposable absorbent insert for a two-piece wearable absorbent article having features for the containment and absorption of bodily exudates. The insert may be adapted to be used with an outer cover and may have containment and absorption features including cuff structures that prevent soiling of the outer cover by the wearer'"'"'s exudates, so that the outer cover may be reused after an exudation event and change of inserts. The insert may have features to enhance containment, absorption, economy of materials and/or fit that makes it asymmetric about its lateral axis, and may have features that direct a user to install the insert with correct front-rear orientation relative the outer cover and/or the wearer.

Claims

1. A disposable absorbent insert for use with an outer cover adapted to be worn about a wearer'"'"'s lower torso, the insert having a longitudinal length, an insert forward region, an insert rearward region, and a lateral axis between the forward and rearward regions and equally dividing the longitudinal length, an inner wearer-facing surface, and an outer garment-facing surface, the insert comprising:

a liquid permeable topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet;

left and right dual leg gasketing systems each bonded to one or both of the topsheet and backsheet, each dual leg gasketing system comprising an inner cuff disposed laterally inwardly of an outer cuff, each of the inner and outer cuffs comprising at least one longitudinal elastic member sandwiched or enveloped by one or more web materials; and

a fastener component.

2. The insert of claim 1 further comprising an insert indicium disposed thereon, wherein the insert is asymmetric across the lateral axis, and is adapted to function on and/or fit the wearer optimally with the insert forward region disposed proximate to a torso front region of the wearer'"'"'s lower torso and the insert rearward region disposed proximate to a torso rear region of the wearer'"'"'s lower torso;

and

wherein the insert indicium provides information to a user concerning correct front-rear orientation of the insert with respect to the outer cover or the wearer.

3. The insert of claim 1 wherein the fastener component is disposed on and laterally centered in the insert rearward region, the fastener component being adapted so as to force-couple not more than about 50% of the lateral width to the outer cover when the insert is completely installed within the outer cover.

4. The insert of claim 3 further comprising an end support stiffener in the insert rearward region.

5. The insert of claim 1 wherein the absorbent core further comprises a layer comprising distributed particles of superabsorbent polymer or absorbent gelling material captured by a thermoplastic adhesive composition.

6. The insert of claim 1 wherein the backsheet is formed of a vapor permeable material.

7. The insert of claim 1 wherein the inner cuff is formed of a vapor permeable material.

8. The insert of claim 2 wherein the fastener component serves as the insert indicium by being cooperative with a cooperating component of the outer cover to effect fastening with correct front-rear orientation of the insert with respect to the outer cover, and by not being cooperative with a component of the outer cover to effect fastening with incorrect front-rear orientation of the insert with respect to the outer cover.

9. The insert of claim 2 wherein the insert indicium is visual or tactile.

10. The insert of claim 2 wherein the insert is asymmetric about the insert lateral axis by having a difference across the insert lateral axis selected from the group consisting of weight, absorbent capacity, weight of superabsorbent polymer or absorbent gelling material present, wearer-facing surface area, lateral width, and combinations thereof.

11. The insert of claim 1 wherein the inner cuff is formed of web material comprising N-fibers.

12. The insert of claim 1 wherein the inner cuff and outer cuff of each of the dual leg gasketing systems is formed of a single continuous web material.

13. The insert of claim 12 wherein the single continuous web material is bonded to the topsheet on a wearer-facing surface thereof.

14. The insert of claim 12 wherein the single continuous web material is bonded between the topsheet and the backsheet.

15. The insert of claim 12 wherein the single continuous web material is bonded to the backsheet on a garment-facing surface thereof.

19. The insert of claim 1 wherein the respective standing heights of the inner cuff and outer cuff are within 30 percent of each other.

16. A disposable absorbent insert for use with an outer cover adapted to be worn about a wearer'"'"'s lower torso, the insert having a longitudinal length, an insert forward region, an insert rearward region, and a lateral axis between the forward and rearward regions and equally dividing the longitudinal length, an inner wearer-facing surface, and an outer garment-facing surface, the insert comprising:

a liquid permeable topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet;

left and right dual leg gasketing systems, each dual leg gasketing system comprising an inner cuff extending from a line of attachment along a wearer-facing side of insert, the line of attachment disposed laterally inwardly of an outer cuff defining a longitudinal side edge of the insert, each of the inner and outer cuffs comprising at least one longitudinal elastic member sandwiched or enveloped by one or more web materials; and

a fastener component.

17. The insert of claim 16 wherein the inner cuff is formed of web material separate and distinct from materials forming the topsheet and backsheet, the insert further comprising a longitudinal, substantially continuous deposit of adhesive between the web material of the inner cuff and the backsheet.

20. The insert of claim 16 wherein the respective standing heights of the inner cuff and outer cuff are within 30 percent of each other.

18. A disposable absorbent insert for use with an outer cover adapted to be worn about a wearer'"'"'s lower torso, the insert having a longitudinal length, longitudinal side edges, an insert forward region, an insert rearward region, and a lateral axis between the forward and rearward regions and equally dividing the longitudinal length, an inner wearer-facing surface, and an outer garment-facing surface, the insert comprising:

a liquid permeable topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet;

a pair of standing cuffs, each extending from proximal location at a line of attachment along a wearer-facing side of insert, to a distal end, the line of attachment disposed laterally inwardly of one of the longitudinal side edges, and each standing cuff comprising at least one longitudinal elastic member sandwiched or enveloped by one or more web materials;

a longitudinal, substantially continuous deposit of adhesive between the one or more web materials and the backsheet; and

a fastener component.
