Disposable Diaper

July 10, 2007

A disposable diaper was granted a patent. It comprises a basic absorbent batt structure and at least one supplementary absorbent batt structure. The basic absorbent batt structure has a liquid-pervious body faceable surface and a liquid-impervious garment faceable surface, a front waist region, a rear waist region and a crotch region. The supplementary absorbent batt structure has a liquid-pervious body faceable surface, an opposite lower surface, a proximal end portion lying in the front waist portion and a distal end portion lying in the crotch region. Placed upon the body faceable surface of the basic absorbent batt structure, the distal end portion terminates in a free end. An elastic member under an extension in a transverse direction extends in the transverse direction across the diaper and has transversely opposite end portions connected to side edge portions of the basic and supplementary absorbent batt structures. Opposing surfaces extend between the opposite end portions. The elastic member is positioned between the supplementary batt structure and the basic absorbent batt structure and is spaced from the free end in a zone of the distal end portion and adjacent the proximal end portion. Contraction of the elastic member causing the side edge portions of the supplementary absorbent batt structure to be pulled nearer to a longitudinal center line of the diaper so that the distal end portion of the supplementary absorbent batt structure curves so as to delineate a circular arc which is convex upward with respect to the body faceable surface of the basic absorbent batt structure and consequently a pocket opening from the front waist region toward the crotch region is formed between the basic and supplementary absorbent batt structures, the contraction causing each of the opposing surfaces of the elastic member to be spaced from the supplementary absorbent batt structure and the basic absorbent batt structure.
