Abstract

A pant-like absorbent garment having a swellable absorbent core positioned between an outer cover and a body side liner at least partially bonded to the outer cover. The swellable absorbent core is swellable to a final thickness (t f ) which is at least three times an initial thickness (t i ) of the swellable absorbent core; t f ≧3t i . The significant swelling renders the garment suitable for use as a toilet training aid.

Claims (62)

1. A disposable training pant comprising:

an absorbent chassis defining a front waist region, a back waist region and a crotch region interconnecting the front waist region and the back waist region;

an outer cover;

a swellable absorbent core positioned between the outer cover and the bodyside liner, the absorbent core having an overall absorbent capacity of about 130 grams to about 200 grams and an initial thickness (t i ), the absorbent core swellable to a final thickness (t f ), t f ≧3t i ,

the disposable training pant having an overall absorbent capacity of about 300 g or less.

2. The disposable training pant of claim 1 wherein t f ≧5t i .

3. The disposable training pant of claim 1 wherein the initial thickness is less than about 2.0 mm.

5. The disposable training pant of claim 1 wherein the initial thickness is less than about 1.0 mm.

6. The disposable training pant of claim 1 wherein the initial thickness is about 0.5 mm to about 1.0 mm.

7. The disposable training pant of claim 1 wherein the absorbent article training pant has an initial thickness less than about 3.0 mm.

8. The disposable training pant of claim 1 wherein the training pant has an initial thickness less than about 2.5 mm.

9. The disposable training pant of claim 1 wherein the training pant has an initial thickness less than about 2.0 mm.

10. The disposable training pant of claim 1 wherein the absorbent core has a width of at least about 25 mm.

11. The disposable training pant of claim 1 wherein the absorbent core has a width of at least about 50 mm.

12. The disposable training pant of claim 1 wherein the absorbent core has a width of at least about 100 mm.

13. The disposable training pant of claim 1 wherein the absorbent core has a length of about 25 mm to about 700 mm.

14. The disposable training pant of claim 1 wherein the absorbent core has a length of about 250 mm to about 600 mm.

15. The disposable training pant of claim 1 wherein the absorbent core has a length of about 300 mm to about 550 mm.

16. The disposable training pant of claim 1 wherein the absorbent core has an overall absorbent capacity of about 140 g to about 180 g.

17. The disposable training pant of claim 1 wherein the absorbent core comprises a high swelling absorbent material.

18. The disposable training pant of claim 1 further comprising a surge layer placed over the absorbent core.

19. A disposable training pant comprising:

an absorbent chassis having a front waist region and a back waist region joined to define a pant configuration having a waist opening and a pair of leg openings, and an outer cover and a bodyside liner which is connected to the outer cover in a superposed relation; and

an absorbent core located between the outer cover and the bodyside liner, the absorbent core having a total absorbent capacity of about 130 grams to about 200 grams and not greater than about three times an anticipated insult volume;

the absorbent core being swellable upon an insult to a final wet thickness at least about three times greater than an initiai dry thickness of the absorbent core.

20. The disposable training pant of claim 19 wherein the final wet thickness is at least about five times greater than the initial dry thickness.

21. The disposable training pant of claim 19 wherein the initial dry thickness is less than about 2.0 mm.

22. The disposable training pant of claim 19 wherein the initial dry thickness is less than about 1.5 mm.

23. The disposable training pant of claim 19 wherein the initial dry thickness is less than about 1.0 mm.

24. The disposable training pant of claim 19 wherein the initial dry thickness is about 0.5 mm to about 1.0 mm.

25. The disposable training pant of claim 19 wherein the initial dry thickness is about 0.60 mm to about 0.85 mm.

26. The disposable training pant of claim 19 wherein the final wet thickness is greater than about 3.75 mm.

27. The disposable training pant of claim 19 wherein the training pant has an initial thickness less than about 3.0 mm.

28. The disposable training pant of claim 19 wherein the training pant has an initial thickness less than about 2.5 mm.

29. The disposable training pant of claim 19 wherein the training pant has an initial thickness less than about 2.0 mm.

30. The disposable training pant of claim 19 wherein the absorbent core has a width of at least about 25 mm.

31. The disposable training pant of claim 19 wherein the absorbent core has a width of at least about 50 mm.

32. The disposable training pant of claim 19 wherein the absorbent core has a width of at least about 100 mm.

33. The disposable training pant of claim 19 wherein the absorbent core has a length of about 25 mm to about 700 mm.

34. The disposable training pant of claim 19 wherein the absorbent core has a length of about 250 mm to about 600 mm.

35. The disposable training pant of claim 19 wherein the absorbent core has a length of about 300 mm to about 550 mm.

36. The disposable training pant of claim 19 wherein the absorbent core comprises a high swelling absorbent material.

37. A disposable training pant comprising:

an absorbent chassis defining a front waist region, a back waist region and a crotch region interconnecting the front waist region and the back waist region;

an outer cover;

a bodyside liner at least partially bonded to the outer cover;

a swellable absorbent core positioned between the outer cover and the bodyside liner, the absorbent core having an overall absorbent capacity of about 130 grams to about 200 grams and an initial thickness (t i ), the absorbent core swellable to a final thickness (t f ), whereby swelling of the absorbent core as a result of a first insult creates a void area in the swellable absorbent core that enhances uptake and fluid distribution during subsequent insults, and t f ≧3t i ,
