20110004181 | DISPOSABLE PANTS-TYPE WEARING ARTICLE - The present invention is to provide a disposable pants-type wearing article improved so that urine and feces should not mixed together within the wearing article. This object is achieved by a unique construction such that a crotch region of a pants-type wearing article is provided above an inner surface of the crotch region with a functional sheet extending across the crotch region and bonded thereto along opposite side edges of the crotch region | 01-06-2011 |
20110046598 | WEARING ARTICLE AND METHOD FOR MAKING THE SAME - The present invention aims to provide an improved wearing article allowing the dimension of the leg-openings to be adequately large without causing leakage of urine. A chassis is formed in a crotch region with an opening extending through inner and outer sheets in the thickness direction. The opening extends across the crotch region in a longitudinal direction partially into front and rear waist regions and also extends through parts of respective waist region elastic sheets in the thickness direction. An absorbent panel functioning as a liquid-absorbent structure is attached to the skin-facing surface of the chassis to cover the opening. The liquid-absorbent panel is joined along both side edges thereof to the inner sheet and the waist region elastic sheets by bonding or sealing technique and along front and rear ends thereof to the waist region elastic sheets by bonding or sealing technique. | 02-24-2011 |
20110048617 | METHOD FOR MAKING DIAPER - A method of making a diaper includes: forming the continuous sheet at a distance in a width direction from an imaginary center line M bisecting the width dimension of the continuous sheet with let-through openings for passage of feces at a regular pitch, bonding absorbent panels, each having an absorbent core to the middle section of a sheet piece having an area larger than the area of the absorbent core; coating the surface of the continuous sheet opposite to the surface to which the absorbent panels have been bonded with hot melt adhesive HM; and cutting the assembly of the continuous sheet and the absorbent panels along the imaginary vertical line V defined between each pair of the adjacent absorbent panels at the regular pitch to obtain the diapers. | 03-03-2011 |
20110054434 | DISPOSABLE PANTS-TYPE DIAPER - A disposable pants-type diaper includes an innermost sheet lying between a liquid-pervious inner sheet covering a bodily fluid-absorbent core and diaper wearer's skin and attached to the inner sheet to form a body waste retaining space. The innermost sheet is formed with a front opening allowing the passage of urine into the body waste retaining space and a rear opening allowing the passage of feces into the body waste retaining space. A portion of the innermost sheet extending between the front opening and the rear opening droops down and a lower end thereof to form a separator. | 03-03-2011 |
20110060304 | DISPOSABLE PANTS-TYPE DIAPER - A crotch region of a disposable pants-type diaper includes a bodily fluid absorbent structure comprising a liquid-pervious inner sheet, a liquid-impervious outer sheet and a bodily fluid absorbent core and, in addition, a body waste retaining space formed by the inner sheet and the innermost sheet member interposed between the inner sheet and the diaper wearer's skin. Segments of the innermost sheet member defining peripheral edges of a front opening and a rear opening face to each other in a front-back direction and are bonded to each other via two spacers spaced from each other in a transverse direction to form a space. A portion of the innermost sheet member extending between the segments sags toward the lowermost portion of the crotch region to form a separator. | 03-10-2011 |
20110060305 | WEARING ARTICLE - A wearing article includes front and rear waist regions joined together. A joint strength of joint arrays along the front and rear waist regions is generally uniformed. A chassis is formed along front waist region's side edges and rear waist region's side edges with the joint arrays. A liquid-absorbent structure includes front and rear ends opposed to each other in a longitudinal direction and extending in a transverse direction. The front end is covered with a front waist sheet and the rear end is covered with a rear waist sheet. Along the respective joint arrays, the front and rear waist sheets are spaced from each other in the longitudinal direction. | 03-10-2011 |
20110060306 | PANTS TYPE DISPOSABLE DIAPER - The present invention aims to provide a pants type disposable diaper free from noticeable gathers formed on the innermost side of the crotch region. In the crotch region of the pants type disposable diaper, the bodily fluid-absorbent core is sandwiched between the liquid-permeable inner sheet and the liquid-impermeable outer sheet. Further inside the inner sheet, the innermost sheet is provided and this innermost sheet prevents the inner sheet from coming in contact with the wearer's skin. The innermost sheet is joined, in the regions extending in the vicinity of the ends thereof opposite in the front-back direction A, to at least one of the inner sheet and the outer sheet. The innermost sheet includes, in its region defined on the transverse center line P of the diaper, the tuck extending downward toward the inner sheet. | 03-10-2011 |
20110066125 | DISPOSABLE PANTS-TYPE DIAPER - A disposable pants-type diaper with the innermost sheet member interposed between a liquid-pervious inner sheet covering a bodily fluid-absorbent structure and the diaper's skin. The innermost sheet member is formed with a front opening and a rear opening communicating with a body waste retaining space defined between the inner sheet and the innermost sheet member. A portion of the innermost sheet member extending between these two openings is folded and joined together in a pair of joints arranged on a vertical center line of the diaper and extends downward toward the inner sheet to form a separator. | 03-17-2011 |
20120022488 | WEARING ARTICLE - A wearing article has a chassis and leg elastic members of a flat band shape that are attached to the chassis along leg side edges thereof. The chassis has regions each of which overlaps one of the leg elastic members and includes at least one series of depressions extending along the respective leg side edge. | 01-26-2012 |
20120029460 | DISPOSABLE WEARING ARTICLE - A disposable wearing article includes, in an elastic region in a periphery of at least a waist- or leg-opening, an elastic band formed of a fibrous non-woven fabric which is elastically contractible and has a plurality of first gathers extending in a length direction so as to undulate in a width direction thereof. | 02-02-2012 |
20120035564 | PULL-ON ARTICLE - A pull-on article comprises a chassis including a first waist region, a second waist region and a crotch region between the first and second waist regions. The article is shaped into a pull-on having a waist and a pair of leg openings by weld-bonding side edges of the first and second waist regions. The waist and leg openings are respectively provided along respective edged defining the waist and leg openings with waist and leg elastic members which are respectively formed into a tape shape having a relatively width dimension. The first and second waist regions, and the leg and waist elastic members are respectively formed of a fibrous non-woven fabric including at least thermoplastic fibers wherein the leg and waist elastic members include at least elastically extendible fibers as the thermoplastic fibers. | 02-09-2012 |
20130060220 | DISPOSABLE WEARING ARTICLE - The present invention provides a disposable wearing article adapted to inhibit sweating and an uncomfortable stuffiness. Front and rear waist regions of a disposable wearing article have inner surfaces thereof at least partially formed of elastic sheets. The elastic sheets are made of a mixture of elastic fibers and inelastic fibers and formed with ridges and grooves. The elastic sheets have a thickness in the ridges repetitively reduced and restored as the elastic sheets repeat elastic stretch and contraction in the waist circumferential direction. | 03-07-2013 |
