Patent ID: 7238175

Claim:
A disposable diaper comprising: a basic absorbent batt structure; at least one supplementary absorbent batt structure; said basic absorbent batt structure having a liquid-pervious body faceable surface and a liquid-impervious garment faceable surface, and a front waist region, a rear waist region and a crotch region; said supplementary absorbent batt structure having a liquid-pervious body faceable surface and an opposite lower surface, and a proximal end portion lying in said front waist portion and a distal end portion lying in said crotch region, and being placed upon the body faceable surface of said basic absorbent batt structure, the distal end portion terminating in a free end; an elastic member under an extension in a transverse direction extending in said transverse direction across the diaper, having transversely opposite end portions connected to side edge portions of said basic and supplementary absorbent batt structures, and having opposing surfaces that extend between said opposite end portions, the elastic member being positioned between the supplementary batt structure and the basic absorbent batt structure and being spaced from said free end in a zone of said distal end portion and adjacent said proximal end portion; and contraction of said elastic member causing the side edge portions of said supplementary absorbent batt structure to be pulled nearer to a longitudinal center line of said diaper so that said distal end portion of said supplementary absorbent batt structure curves so as to delineate a circular arc which is convex upward with respect to the body faceable surface of said basic absorbent batt structure and consequently a pocket opening from said front waist region toward said crotch region is formed between said basic and supplementary absorbent batt structures, said contraction causing each of said opposing surfaces of the elastic member to be spaced from said supplementary absorbent batt structure and said basic absorbent batt structure.
