Claim 1
Independent Claim
388 words
A formed and washable diaper comprised of a multiplicity of layers of material including a non-allergenic outer layer forming a moisture barrier cover, a moisture retentive mildew resistant washable felt layer, a middle layer of batting forming the frame of the diaper, and an inner facing layer of soft non-irritating absorbent washable fabric, said diaper having a particular body enclosing configuration due to its construction which includes an hour-glass outline with each of the hour-glass shaped sides forming a continuous sculpted crescent shaped concave curve with the top and bottom edges of the diaper being generally curved slightly convex upward and downward respectively, the upper end of said diaper being slightly longer in lateral length than the bottom end whereby when the diaper is placed on the wearer with the top end disposed at the back of the wearer's body and with the bottom end pulled up between the wearer's legs and disposed on the front of the wearer's body on the stomach, the two lateral edges of the top end of the diaper will wrap around the wearer's body from behind and overlap the two lateral edges at the bottom end of the diaper disposed on the wearer's stomach, the laterally curved vertically disposed edges of the diaper being provided with an elastic edging which is secured to said material for a portion of the length of the curved edges which surround the wearer's leg when the diaper is disposed in operative position whereby when the elastic is released after being secured to the diaper in a stretched condition along the edge of said diaper and allowed to retract, said diaper is retracted into a U-shaped configuration with the resulting opposed portions being the front and rear flaps of said diaper, the outer edges of said inner, middle, and outer layers of said material being co-extensive throughout the extent of the configuration of the diaper, said absorbent felt layer being disposed in a narrow rectangular strip from the top to the bottom down the middle of said diaper to provide extra absorbency throughout the middle portion of said diaper, and tabs formed by the top and bottom lateral edges or corners of said diaper being provided with adjustable stick and grip fasteners for securing said overlapping lateral edges together to hold the diaper on the wearer's body.
