  • Patent number: 12629292
    Abstract: The problem is to provide excellent slipping-down preventive property with a simpler structure. This problem is solved by an attachable-type disposable wearing article configured so that, in the natural length state, as the unfixed area contracts, a pair of side areas of the end flap positioned lateral to the unfixed area are obliquely drawn closer as they extend backward, which results in formation of transverse portion extending in the width direction at the back edge of intermediate area located between the pair of side areas, while obliquely backward portions are formed at the back edges of the side areas positioned more backward as they extend laterally, and in the spread state, the back edge of the end flap extends along the width direction over the extent including from one of the obliquely backward portions to the other.

    Abstract: The problem is to provide excellent slipping-down preventive property with a simpler structure. This problem is solved by an attachable-type disposable wearing article configured so that, in the natural length state, as the unfixed area 52 contracts, a pair of side areas 60 of the end flap EF positioned lateral to the unfixed area 52 are obliquely drawn closer as they extend backward, which results in formation of transverse portion 62 extending in the width direction WD at the back edge of intermediate area 61 located between the pair of side areas 60, while obliquely backward portions 63 are formed at the back edges of the side areas 60 positioned more backward as they extend laterally, and in the spread state, the back edge of the end flap EF extends along the width direction WD over the extent including from one of the obliquely backward portions 63 to the other.

    Abstract: A disposable diaper has, in a dorsal section of the outer sheet, a fastening tape extending orthogonally to a dorsoventral direction. The fastening tape includes: a base portion on the outer sheet; a main unit section on a distal end of the base portion; and an engagement portion on a distal end of the main unit section. A dorsal end edge of the main unit section is continuous with a dorsal end edge of the engagement portion, and a ventral end edge of the main unit section is continuous with a ventral end edge of the engagement portion. The fastening tape has a slit portion formed in an extending direction. The main unit section has elastically stretchable members formed in the extending direction at intervals in a dorsoventral direction. A ventral portion and a dorsal portion in the engagement portion extend more distally than a central portion thereof.
