DISPOSABLE DIAPER FEATURING CROTCH TENSIONING MEANS FOR IMPROVED LEAKAGE RESISTANCE AND FIT

摘要

A disposable diaper (10) having front and rear waist portions and (22, 24) comprising a liquid permeable topsheet (50); a liquid impermeable backsheet (30) affixed to the topsheet; an absorbent core (14) interposed between the topsheet (50) and the backsheet (30); a crotch portion located intermediate the front and rear waist portions; a pair of side flaps (27); and crotch tension means (60) associated with each of the side flaps. The absorbent core (14) has oppositely disposed end portions and a pair of longitudinally disposed side edges therebetween. The crotch tensioning means (60) further comprises one or more elasticized members (65) extending from an attachment area (70) in the crotch portion of the diaper, across the respective side flap, to a location longitudinally outside of the crotch portion. The crotch tensioning means (60) thereby tend to impose outward lateral tension on the crotch portion of the diaper when in use. The attachment areas (70) for such crotch tensioning means are preferably oppositely disposed within the crotch portion of the diaper and are laterally spaced from one another at a width of less than approximately 153 mm. The resulting disposable diaper (10) provides improved aesthetic fit on the wearer and improved containment of voided materials.
