  • Disposable diaper with center folded edges
    Patent number: 4216773
    Abstract: A disposable diaper that is better fitting and has the absorbent material more advantageously located is made by cutting two longitudinal slits in the front end of a generally rectangular absorbent pad. Flaps are generated by a fold line originating on the edges of the pad, at or near the rear corners, and projected to intersect the adjacent slits at or near their inner ends. The flaps are folded inwardly to create a generally Y-shaped diaper having multiple layers of absorbent material in the area of heaviest wetting.
