摘要

abstract "extensible absorbent article structure, absorbent article comprising said extensible structure and process for forming extensible absorbent article structure". an extensible absorbent article structure including: a leaf member (12s) which is composed of an air permeable material (120) and has a plurality of folds (80) disposed at intervals so as not to overlap in a fallen state , and overlapping inter-fold portions (85) in the state in which the folds (80) are sagging; and resilient and resilient elongate members (90) provided between opposing surfaces (80a and 80b) of the pleats (80) along a longitudinal direction of the pleats (80). the pleats 80 are continuously or intermittently joined in the longitudinal direction of the pleats 80 so that at least the opposing surfaces 80a and 80b of the base parts 81 are not spaced apart. outer surfaces of the pleats (80) are not joined to the inter-pleat portions (85) except at the two longitudinal ends of the pleats (80). resilient and resilient members (90) are disposed in the pleats (80) at the tip side with respect to the base parts (81) and at least the two ends of resilient and resilient members (90) are fixed between opposing surfaces (80a). and 80b) of the pleats (80). the pleats (80) and the inter-pleat portions (85) are contracted by contraction of resilient and elastic members (90). 1/1
