Patent number: 6443937Abstract: A fastening system for a garment such as a disposable diaper includes a hook panel having a plurality of hook elements and a loop panel having a plurality of loop elements. The hook panel includes a base panel having a top surface on which the hook elements extend and a back surface. The back surface of the base panel has a secured region and a non-secured region with respect to the garment. The non-secured region is defined toward one end from which the hook panel can be progressively released from the loop panel toward the other opposite end. The fastening system thereby reduces the chance that the hook panel might be readily and unintentionally released from the loop panel during use of the garment.Type: GrantFiled: January 14, 1997Date of Patent: September 3, 2002Assignee: Uni-Charm CorporationInventor: Michiyo Matsushita

Publication number: 20010041248Abstract: A breathable and liquid-impervious composite sheet includes a flexible, breathable and liquid-impervious thermoplastic synthetic resin film and heat-sealable nonwoven fabric layers placed upon opposite surface of the film. The film has a basis weight of 0.098˜0.392 N/m2 and a thermal shrink percentage of 3˜18% under 60° C. thermal atmosphere while the nonwoven fabric layers 3A, 3B have a basis weight of 0.049˜0.294 N/m2. The sheet is formed with plural arrays of heat-sealed regions each extending in transverse direction Y and spaced one from another in longitudinal direction X intersecting the transverse direction Y. Between each pair of the adjacent heat-sealed regions, the nonwoven fabric layers describe circular arcs which are convex outward in a thickness direction of the sheet from the opposite surfaces of the film.Type: ApplicationFiled: April 26, 2001Publication date: November 15, 2001Inventors: Michiyo Matsushita, Yasushi Atsuta

Publication number: 20010032346Abstract: A disposable gown includes front and rear trunk regions. The front trunk region has a first neckline extending transversely and first armhole lines rectilinearly and obliquely extending downward from lateral ends of the first neckline toward respective armpits. The rear trunk region has a second neckline extending transversely and second armhole lines rectilinearly and obliquely extending downward from lateral ends of the second neckline toward the armpits. A crossing angle &thgr;1 between both first extensions generated when the first armhole lines are extended upward from lateral ends of the first neckline is larger than a crossing angle &thgr;2 between the both second extensions generated when the second armhole lines are extended upward from lateral ends of the second neckline.Type: ApplicationFiled: April 4, 2001Publication date: October 25, 2001Inventors: Michiyo Matsushita, Akiko Saito

Patent number: 6293937Abstract: Trunks-type disposable pants that include a pair of inner sheets and a pair of outer sheets. The inner sheets have cutouts depressed from the upper ends toward the lower ends and liquid-absorbent panels attached to opposed surfaces of the inner sheets in the vicinity of the respective cutouts. The opposed surfaces of the inner sheets may be bonded together by means of bond lines extending in parallel to the cutouts and partially extending below the liquid-absorbent panels. Opposed surfaces of the inner sheets and the outer sheets are bonded together along the front and rear side portions of these sheets.Type: GrantFiled: February 16, 2001Date of Patent: September 25, 2001Assignee: Uni-Charm CorporationInventors: Michiyo Matsushita, Takeshi Hanajiri

Patent number: 6289519Abstract: Pants that comprise a pair of intermediate body sheets, positioned in plane symmetry to each other and respectively contoured by upper, lower, inner and outer edges, and a pair of lateral body sheets also positioned outside the respective intermediate body sheets and respectively contoured also by upper, lower, inner and outer edges. Each of the intermediate body sheets is formed between the inner and outer edges with an arcuate cutout extending convexly from the upper edge, toward the lower edge the intermediate body sheets being put flat and sealed together along a sealing line defined by the cutouts but leaving a narrow marginal edge free. The intermediate body sheets and the lateral body sheets are placed flat and sealed together along sealing lines defined by inner and outer edges thereof, leaving narrow marginal regions free outside the inner and outer edges.Type: GrantFiled: October 16, 2000Date of Patent: September 18, 2001Assignee: Uni-Charm Co., LTDInventors: Masaki Murakami, Michiyo Matsushita, Akira Myoga, Hitomi Ishikawa

Patent number: 6027485Abstract: Medium members such as thread are provided between woven fabric sheet such as warp knitting serving as the other sheet and base member, forming linear raised portions in the woven fabric sheet. The density of woven fabric sheet at the inclined portions to either side of these raised portions becomes coarse and the gaps between fine filaments on the woven fabric sheet spread, so that retaining heads of one sheet can easily enter and so that the fine filaments easily become hooked to the base portion of the retaining heads. Consequently, the retaining of the one sheet and the other sheet in strengthened, and the peeling strength is improved.Type: GrantFiled: May 14, 1997Date of Patent: February 22, 2000Assignee: Uni-Charm CorporationInventors: Michiyo Matsushita, Akiko Hirano, Ikuo Akiyama
