Abstract
Abstract A disposable diaper is provided with a plurality of scored fold lines arranged in a symmetrical, complex pattern including a central dividing line so that the diaper can be folded on itself prior to use. Four pairs of inwardly directed folds originate from the side edges of the diaper to define two pairs of angular symmetrical areas of essentially triangular configuration having a common base on opposites sides of the central dividing line. The configuration of the scores is such that when the diaper is folded in half, the said angular symmetrical areas form a double gusset fold. This preforms the diaper into a particularly useful form which is easily fitted to an infant so that it snugly conforms to his legs when the diaper is pinned in place.
