Abstract
The present invention provides a child's disposable absorbent training pant having an improved waist elastic system. The waist elastic system has a selected maximum magnitude of decay over the first three cycles at a specific extension, thereby providing a substantially uniform low tension over a wide size range, a more comfortable fit, and improved ease of use.
Claims32
A waist elastic system for a disposable absorbent pant comprising a chassis including a front panel, a back panel, a crotch panel, and an absorbent structure on said crotch panel, said front panel and said back panel being selectively joined to form a waist opening and a pair of leg openings, said waist elastic system comprising:
- an elongate sleeve member defining an elongate passage therein, and being generally peripherally disposed about said waist opening, and
- an elongate elastic member disposed within said elongate passage,
- said waist elastic system having a maximum magnitude of decay of about 125 grams at an extension of about 300 millimeters over the first three cycles.
A waist elastic system for a disposable absorbent pant comprising a chassis including a front panel, a back panel, a crotch panel, and an absorbent structure on said crotch panel, said front panel and said back panel being selectively joined to form a waist opening and a pair of leg openings, said waist elastic system comprising:
- an elongate sleeve member defining an elongate passage therein, and being generally disposed about said waist opening, and
- an elongate elastic member disposed within said elongate passage,
- said waist elastic system having a maximum magnitude of decay of about 90 grams at an extension of about 250 millimeters over the first three cycles.
A waist elastic system for a disposable absorbent pant comprising a chassis including a front panel, a back panel, a crotch panel, and an absorbent structure on said crotch panel, said front panel and said back panel being selectively joined to form a waist opening and a pair of leg openings, said waist elastic system comprising:
- an elongate sleeve member defining an elongate passage therein, and being generally peripherally disposed about said waist opening, and
- an elongate elastic member disposed within said elongate passage,
- said waist elastic system having a maximum magnitude of decay of about 70 grams at an extension of about 200 millimeters over the first three cycles.
A disposable absorbent pant comprising:
- a chassis including a front panel, a back panel, a crotch panel, and an absorbent structure on said crotch panel, said front and said back panel being joined together to form a waist opening and a pair of leg openings,
- said chassis further including a waist border comprising a layer of material generally peripherally disposed about said waist opening, and
- a waist elastic system generally peripherally joined to said waist border, said waist elastic system having a maximum magnitude of decay of about 90 grams at an extension of about 250 millimeters over the first three cycles.
In a disposable absorbent pant comprising a chassis including a front panel and a back panel joined together to form a waist opening and a pair of leg openings, a crotch panel, and an absorbent structure disposed on said crotch panel;
- a waist elastic system having a maximum magnitude of decay of about 150 grams at an extension of about 300 millimeters over the first three cycles.
