Patent ID: 7326193

Claim:
A disposable pants-type wearing article, comprising: a front waist region, a rear waist region and a crotch region, said crotch region being provided with a body fluid absorbent assembly extending over said crotch region and further into said front and rear waist regions; said body fluid absorbent assembly having transversely opposite side edges extending generally parallel to each other into said front and rear waist regions and longitudinally curving in a generally U-shape with an inner surface thereof opposed to itself in said front and rear waist regions; wherein, in said crotch region, said body fluid absorbent assembly has: a pair of first folding guide lines extending from either a midpoint of a crossline extending across said crotch region or from two points on said crossline, which are equidistant in opposite directions from said midpoint, to said transversely opposite side edges of said body fluid absorbent assembly, respectively, wherein said first folding guide lines diverge toward said front waist region and are inclined at a crossing angle α with respect to said crossline, a pair of second folding guide lines extending from said midpoint or said two points to said transversely opposite side edges of said body fluid absorbent assembly, respectively, wherein said second folding guide lines diverge toward said rear waist region and are inclined at a crossing angle β with respect to said crossline, a pair of folded portions defined between said first and second folding guide lines, wherein said body fluid absorbent assembly is folded inwardly along said first and second folding guide lines to define said folded portions, a first non-folded portion extending from said first folding guide lines toward said front waist region, and a second non-folded portion extending from said second folding guide lines toward said rear waist region; and wherein said body fluid absorbent assembly is configured so that said first non-folded portion has a relatively small extent and said second non-folded portion has a relatively large extent; and wherein each of said non-folded portions extends continuously without being folded from one of the transversely opposite side edges of said body fluid absorbent assembly to the other, and from the respective first or second folding guide lines to one of longitudinally opposite end edges of said body fluid absorbent assembly in the respective front or rear waist region.
