Abstract

A wing for an adult incontinent device is disclosed. The adult incontinent device has a chassis with a lateral attachment surface. The wing includes a stretch laminate with at least one nonwoven layer and at least one elastic layer. The nonwoven layer and the elastic layer are bound together in face-to-face contact. The stretch laminate has at least one stretch zone and at least one non-stretch zone. The stretch laminate has no overlap portions between the stretch zone and the non-stretch zone. One end of the wing is affixed to the lateral attachment surface of the chassis.

First claim

We claim:

1. A method for making an adult incontinent device comprising the steps of:
providing a chassis for the adult incontinent device, the chassis having a lateral attachment surface;
affixing a wing to the lateral attachment surface, the wing is a stretch laminate with at least one nonwoven layer and at least one elastic layer, the nonwoven layer and the elastic layer are bound together in face-to-face contact, the stretch laminate has at least one stretch zone and at least one non-stretch zone, the stretch laminate has no overlap portions between the stretch zone and the non-stretch zone; and thereby forming the adult incontinent device; wherein the non-stretch zone comprises no elastic layer.

2. The method of claim 1 wherein the wing has one stretch zone located between two non-stretch zones, and one non-stretch zone is affixed to the lateral attachment surface.

3. The method of claim 1 wherein the wing has at least two stretch zones and at least three non-stretch zones, the stretch zones and the non-stretch zones alternating across the wing, and one non-stretch zone is affixed to the lateral attachment surface.

4. The method of claim 1 wherein the wing has at least two stretch zones and at least one non-stretch zone, the stretch zones and the non-stretch zones alternating across the wing, and one stretch zone is affixed to the lateral attachment surface.

5. The method of claim 1 wherein the stretch laminate comprises a first nonwoven, a second nonwoven, and elastic film sandwiched therebetween.

6. The method of claim 1 wherein the nonwoven is a spunbond nonwoven.

7. The method of claim 1 wherein the stretch zone comprises a laminate of the nonwoven layer and the elastic layer.

8. The method of claim 1 wherein the elastic layer is: activated, non-activated, partially activated; and/or activated to varying degrees.

9. The method of claim 1 wherein the wing further comprises hooks affixed at an end of the wing opposite the lateral attachment surface.

10. The method of claim 1 wherein the wing has a dimension (d 1 ) and d 1 is greater than 100 mm.

11. The method of claim 1 wherein the stretch laminate having no overlap portions between the stretch zone and the non-stretch zone is characterized by the nonwoven layer having a continuous path from the lateral attachment area to either another lateral attachment area on the chassis or a free end of the wing.

12. The wing of claim 11 wherein the stretch zone comprises a laminate of the nonwoven layer and the elastic layer.

13. A wing for an adult incontinent device, the device has a chassis for the adult incontinent device, the chassis has a lateral attachment surface, comprises:
a stretch laminate with at least one nonwoven layer and at least one elastic layer, the nonwoven layer and the elastic layer are bound together in face-to-face contact, the stretch laminate has at least one stretch zone and at least one non-stretch zone, the stretch laminate has no overlap portions between the stretch zone and the non-stretch zone, and one end of the wing is affixed to the lateral attachment surface of the chassis;
wherein the non-stretch zone comprises no elastic layer.

14. The wing of claim 13 further comprising one stretch zone located between two non-stretch zones, and one non-stretch zone is affixed to the lateral attachment surface.

15. The wing of claim 13 further comprising at least two stretch zones and at least three non-stretch zones, the stretch zones and the non-stretch zones alternating across the wing, and one non-stretch zone is affixed to the lateral attachment surface.

16. The wing of claim 13 further comprising at least two stretch zones and at least one non-stretch zone, the stretch zones and the non-stretch zones alternating across the wing, and one stretch zone is affixed to the lateral attachment surface.

17. The wing of claim 13 wherein the stretch laminate comprises a first nonwoven, a second nonwoven, and elastic film sandwiched therebetween.

18. The wing of claim 13 wherein the nonwoven is a spunbond nonwoven.

19. The wing of claim 13 wherein the elastic layer is: activated, non-activated, partially activated; and/or activated to varying degrees.

20. The wing of claim 13 further comprises hooks affixed at an end of the wing opposite the lateral attachment surface.

21. The wing of claim 13 further comprises a dimension (d 1 ) and d 1 is greater than 100 mm.

22. The wing of claim 13 wherein the stretch laminate having no overlap portions between the stretch zone and the non-stretch zone is characterized by the nonwoven layer having a continuous path from the lateral attachment area to either another lateral attachment area on the chassis or a free end of the wing.

23. An adult incontinent device comprises:
a chassis with a lateral attachment surface, and
a wing including a stretch laminate with at least one nonwoven layer and at least one elastic layer, the nonwoven layer and the elastic layer are bound together in face-to-face contact, the stretch laminate has at least one stretch zone and at least one non-stretch zone, the stretch laminate has no overlap portions between the stretch zone and the non-stretch zone, and one end of the wing is affixed to the lateral attachment surface of the chassis: wherein the non-stretch zone comprises no elastic laver.

24. The adult incontinent device of claim 23 further comprising one stretch zone located between two non-stretch zones, and one non-stretch zone is affixed to the lateral attachment surface.

25. The adult incontinent device of claim 23 further comprising at least two stretch zones and at least three non-stretch zones, the stretch zones and the non-stretch zones alternating across the wing, and one non-stretch zone is affixed to the lateral attachment surface.

26. The adult incontinent device of claim 23 further comprising at least two stretch zones and at least one non-stretch zone, the stretch zones and the non-stretch zones alternating across the wing, and one stretch zone is affixed to the lateral attachment surface.

27. The adult incontinent device of claim 23 wherein the stretch laminate comprises a first nonwoven, a second nonwoven, and elastic film sandwiched therebetween.

28. The adult incontinent device of claim 23 wherein the nonwoven is a spunbond nonwoven.

29. The adult incontinent device of claim 23 wherein the stretch zone comprises a laminate of the nonwoven layer and the elastic layer.

30. The adult incontinent device of claim 23 wherein the elastic layer is: activated, non-activated, partially activated; and/or activated to varying degrees.

31. The adult incontinent device of claim 23 further comprises hooks affixed at an end of the wing opposite the lateral attachment surface.

32. The adult incontinent device of claim 23 further comprises a dimension (d 1 ) and d 1 is greater than 100 mm.

33. The adult incontinent device of claim 23 wherein the stretch laminate having no overlap portions between the stretch zone and the non-stretch zone is characterized by the nonwoven layer having a continuous path from the lateral attachment area to either another lateral attachment area on the chassis or a free end of the wing.
