  • Patent number: 8545472
    Abstract: In a pants-type absorbent product, a first middle elastic member is located along a horizontal direction in a middle front part between a pair of leg openings in an outer covering sheet. The first middle elastic member contracts a first sheet and a second sheet, and middle gathers are formed. Thus, it is possible to improve fitting of a middle part to a wearer. In the middle front part, both ends of the first middle elastic member are apart from edges of the pair of leg openings, and a pair of non-contracted parts are provided between the both ends of the first middle elastic member and the edges of the pair of leg openings, to thereby improve flexibility of portions in the vicinities of the leg openings in the outer covering sheet.

  • Patent number: 8353999
    Abstract: In a manufacturing apparatus of an absorbent product, extended elastic yarns to be a first middle elastic member and extended elastic yarns to be leg elastic members are bonded between a first sheet and a second sheet and arranged crossing each other in manufacturing an outer covering sheet. A first middle elastic member and an inclined part of the leg elastic members crossing the first middle elastic member are simultaneously and reliably cut in a crossing area of the both elastic members by first cutting blades tilted relatively to a direction where the first middle elastic member is positioned and second cutting blades tilted relatively to a direction where the inclined part is positioned. Thus, it is possible to easily form the outer covering sheet which maintains elasticity in a required portion and has high flexibility.

  • Patent number: 8066684
    Abstract: This invention provides disposable pants usable as both pants and a diaper, which ensure excellent stretchability to facilitate raising/lowering when putting them on, and the like. The disposable pants have functions of both pants and a diaper, and a left front abdominal part and a right front abdominal part can be expanded to the left and right by breaking left and right breaking parts. The left front abdominal part and right front abdominal part are provided with adhesive pieces attached/detached to/from an adhesive part of a central front abdominal part. The ratio between a lateral dimension of the front abdominal section in a stretched state and a lateral dimension between positions to which the left and right adhesive pieces are bonded, respectively, is set to fall within a range of 0.05?X2/X1?0.55, which ensures stretchability of the front abdominal section.

  • Patent number: 8034039
    Abstract: Disposable pants allow a crotch section and a front abdominal section to be bonded securely while ensuring the stretchability of the front abdominal section in a pants structure in which the crotch section and front abdominal section formed as separate members are bonded. The disposable pants have functions of both pants and a diaper, and a left front abdominal part and a right front abdominal part can be developed to the left and right by breaking left and right breaking parts. The left front abdominal part and right front abdominal part are provided with adhesive pieces to be attached/detached to/from adhesive parts of a central front abdominal part. A crotch section on which an absorber is provided is connected to the central front abdominal part using sheet members so as not to interfere with stretchability of the central front abdominal part resulting from an elastic member.

  • Patent number: 7981100
    Abstract: A disposable absorbent article includes a sheet member, an absorbent core, at least one front leg elastic member, and at least one rear leg elastic member. The leg elastic members intersect at left and right intersections located in a crotch region of the sheet member. The left and right intersections are placed at any position on the outer side in the lateral direction relative to the vicinity of left and right side edges of the absorbent core in the crotch region. The front leg elastic member has left and right front leg contraction-reduced sections located on the outer side in the lateral direction relative to the left and right intersections. The left and right front leg contraction-reduced sections are cut so as to have reduced contractile forces. The rear leg elastic member has left and right front leg contraction-reduced sections located on the outer side in the lateral direction relative to the left and right intersections.

  • Patent number: 7753899
    Abstract: In a rising gathered member 4 of an absorbent main body 3 attached to an external sheet 2, an inward folded base end 4b is joined astride a side end 13a of a top sheet 13 as a top surface of the absorbent main body 3 and a side end 14a of a back sheet 14 so that the rising gathered member 4 rises from a most side edge 3a in a width direction of the absorbent main body 3 and, also, the back sheet 14 of the absorbent main body 3 is attached onto a skin-contacting surface side of a crotch part R of a second external sheet 8 at an inward position at a prescribed width W5 from the most side edge 3a of the absorbent main body 3 as an outermost joint position. With the above constitution, it is possible to effectively prevent any lateral leakage of urine and the like, even if a disposable absorbent article is shifted.
