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 average maximum rate of change of modulus of elasticity over the first three cycles within a specified extension range, thereby providing a substantially uniform low tension over a wide size range, a more comfortable fit, and improved ease of use.
Claims18
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 chassis further including a waist border generally peripherally disposed about said waist opening,
- said waist elastic system generally peripherally joined to said waist border and having an average maximum rate of change of modulus of elasticity over a first three cycles of about 1.96 grams per millimeter in an extension range between about 175 millimeters to about 325 millimeters.
