  • Pant-like disposable absorbent articles with releasable seams and a folded fastening feature
    Patent number: 6579275
    Abstract: A pant-like, disposable absorbent article includes an absorbent chassis, a pair of opposed side panels, at least one releasable joint and at least one folded fastenery. The absorbent chassis defines a pair of laterally opposed side edges and a pair of longitudinally opposed waist edges. The side panels extend between the side edges of the absorbent chassis to define a waist opening and a pair of leg openings in the pant-like disposable absorbent article. Each of the opposed side panels defines a first side margin which is permanently attached to the side edge of the absorbent chassis in one waist region of the absorbent article to provide a permanent joint. At least one of the opposed side panels further defines a second side margin opposite the first side margin which is releasably attached to the side edge of the absorbent chassis in the other waist region of the absorbent article to provide a releasable joint.
