Abstract

A pant-like absorbent garment having a combined leg elastic and leak guard flap feature. A chassis of the absorbent garment includes an outer cover and a body side liner with at least one elastomeric member folded within the body side liner around each of two leg openings defined by the chassis to form a finished edge around each leg opening. The folded edge of the body side liner is then folded again to create a fully functional flap with the appearance of a leg elastic in the crotch area. The resulting absorbent garment has a three-dimensional leg elastic assembly that creates a bucket for containing body fluids, and furthermore, creates a tailored, soft, comfortable leg and side seal.

Claims

1. A pant-like garment, comprising:

a chassis including an outer cover and a body side liner, and defining a waist opening and first and second leg openings;

a liquid impermeable layer adjacent the outer cover and situated between the outer cover and the body side liner; and

at least one elastomeric member folded within and bonded to the body side liner around at least a portion of each of the first and second leg openings thereby forming leak guard flap regions along transverse edges of the body side liner, wherein the body side liner is folded over each of the at least one elastomeric members and is bonded onto itself in a front region and in a back region of the chassis, and the body side liner is bonded to the liquid impermeable layer along inward edges of the leak guard flap regions in at least a portion of a crotch region of the chassis, and distal edges of the leak guard flap regions are not bonded to the liquid impermeable layer in at least a portion of the crotch region of the garment.

2. The pant-like garment of claim 1, wherein the at least one elastomeric member is situated between the liquid impermeable layer and the body side liner around each of the first and second leg openings in the front and back regions of the chassis.

3. The pant-like garment of claim 1, further comprising at least two pairs of side panels bonded between the outer cover and the liquid impermeable layer.

4. The pant-like garment of claim 1, further comprising at least two pairs of side panels integrated with the outer cover, wherein the at least two pairs of side panels at least partially define the first and second leg openings.

5. The pant-like garment of claim 1, wherein the liquid impermeable layer comprises a print-receiving surface such that any printing on the liquid impermeable layer is visible through a nonwoven web layer of the outer cover.

6. The pant-like garment of claim 1, further comprising an absorbent layer between the outer cover and the body side liner.

7. The pant like garment of claim 6, wherein each of the at least one elastomeric members is folded within the body side liner a set distance from the absorbent layer.

8. The pant-like garment of claim 1, wherein the body side liner is zone-treated to create zones of greater liquid permeability between the first and second leg openings compared to zones of lesser liquid permeability adjacent the first and second leg openings.

9. The pant-like garment of claim 1, comprising training pants.

10. The pant-like garment of claim 1, comprising a diaper.

11. The pant-like garment of claim 1, comprising swim wear.

12. The pant-like garment of claim 1, comprising an incontinence garment.

13. An absorbent garment, comprising:

a chassis including an outer cover and a body side liner, and defining a waist opening and first and second leg openings;

a liquid impermeable layer situated between the outer cover and the body side liner, wherein the liquid impermeable layer, the outer cover and the body side liner each include two transverse edges and two longitudinal edges;

a pair of corresponding side panels along each transverse edge of the outer cover; and

at least one elastomeric member situated between the liquid impermeable layer and the body side liner around each of the first and second leg openings thereby forming leak guard flap regions along transverse edges of the body side liner, wherein each of the transverse edges of the body side liner is folded over at least one of the elastomeric members and is bonded onto an inward portion of the body side liner in a front region and in a back region of the chassis, and the body side liner is bonded to the liquid impermeable layer along inward edges of the leak guard flap regions in at least a portion of a crotch region of the chassis, and the transverse edges of the body side liner are not bonded to the liquid impermeable layer in at least a portion of the crotch region of the chassis.

14. The absorbent garment of claim 13, wherein the liquid impermeable layer comprises a print-receiving surface such that any printing on the liquid impermeable layer is visible through a nonwoven web layer of the outer cover.

15. The absorbent garment of claim 13, further comprising an absorbent layer between the liquid impermeable layer and the body side liner.

16. The absorbent garment of claim 15, wherein each of the at least one elastomeric members is folded within the body side liner a set distance from the absorbent layer.

17. The absorbent garment of claim 13, wherein each of the transverse edges of the body side liner is folded over at least one of the elastomeric members, and is folded over and bonded onto itself.

18. The absorbent garment of claim 13, comprising the pair of corresponding side panels attached along each transverse edge of the outer cover between the outer cover and the liquid impermeable layer.

19. The absorbent garment of claim 13, wherein the body side liner is zone-treated to create zones of greater liquid permeability between the first and second leg openings compared to zones of lesser liquid permeability adjacent the first and second leg openings.

20. An absorbent garment, comprising:

a chassis including an outer cover and a body side liner, and defining a waist opening and first and second leg openings;

a liquid impermeable layer situated between the outer cover and the body side liner;

an absorbent layer situated between the liquid impermeable layer and the body side liner;

at least one elastomeric member situated between the liquid impermeable layer and the body side liner around each of the first and second leg openings thereby forming leak guard flap regions along transverse edges of the body side liner, wherein the body side liner is folded over each of the at least one elastomeric members and is bonded onto itself a set distance from the absorbent layer in a front region and in a back region of the chassis, and the body side liner is bonded to the liquid impermeable layer along inward edges of the leak guard flap regions in at least a portion of a crotch region of the chassis, and distal edges of the leak guard flap regions are not bonded to the liquid impermeable layer in at least a portion of the crotch region of the chassis.

21. The absorbent garment of claim 20, further comprising at least two pairs of side panels bonded between the outer cover and the liquid impermeable layer.

22. The absorbent garment of claim 20, further comprising at least two pairs of side panels integrated with the outer cover, wherein the at least two pairs of side panels at least partially define the first and second leg openings.

23. The absorbent garment of claim 20, wherein the liquid impermeable layer comprises a print-receiving surface such that any printing on the liquid impermeable layer is visible through a nonwoven web layer of the outer cover.

24. The absorbent garment of claim 20 wherein each of the at least one elastomeric members is folded within the body side liner a set distance from the absorbent layer.

25. The absorbent garment of claim 20, wherein the body side liner is zone-treated to create zones of greater liquid permeability between the first and second leg openings compared to zones of lesser liquid permeability adjacent the first and second leg openings.
