Disposable Paper Diaper And Method Of Attaching Expansible Members Of The Disposable Paper Diaper

February 12, 2008

A disposable diaper was recently issued a patent. The diaper features an absorbent, a waist opening and right and left leg openings that are formed when the diaper is in use. A plurality of stretchable rubber threads are provided along the peripheral direction of the diaper, at least in a girth area having a lengthwise range extending from an edge of the waist opening to a beginning of the leg openings. The stretchable rubber threads are spaced at intervals in the lengthwise direction of the diaper. The disposable diaper comprises an overall bottom sheet that defines an outer surface of the diaper; a liquid pervious topsheet; and an absorbent main body between the overall bottom sheet and the liquid pervious topsheet. The absorbent main body comprises the absorbent and a liquid impervious back sheet. The absorbent main body is fixed to the diaper so that there is a portion of the girth area where the absorbent main body is not located; and an elastic sheet-shaped member comprising a support sheet positioned between the overall bottom sheet and the liquid pervious top sheet, the stretchable rubber threads are fixed in an elastically stretched state on the support sheet. The support sheet is located on the overall bottom sheet at least in a portion of the area where the absorbent main body is located. The support sheet is discontinuous in the area of the absorbent main body so that the support sheet does not overlap with at least a portion of the absorbent main body.
