  • Patent number: 8622983
    Abstract: A method to incorporate leg elastic members into pant-like disposable absorbent garments, and garments made thereby. In particular embodiments, the method includes supplying elastomeric film laminate first and second body panel webs spaced apart from each other. A continuous first leg elastic member is attached to the first body panel web, and a continuous second leg elastic member is attached to the second body panel web. A continuous leg elastic covering web is attached to both the first body panel web and the second body panel web so as to sandwich the first and second leg elastic members between the leg elastic covering web and the respective body panel web, thereby creating a composite web. In particular embodiments, the present invention can provide an efficient and process friendly technique to cover and hold in place leg elastic members in a pant-style disposable garment that employs elastomeric film laminates.

  • Patent number: 8622984
    Abstract: This invention pertains to a three dimensional disposable panty, subassemblies of the panty, and an apparatus and methods for making the panty and subassemblies. The panty is designed to hold a primary absorbent sanitary pad. The panty may have elasticized leg and waist openings and be stretchable about the hip and stomach regions of a user. the panty provides backup protection to control egress of fluids that leak or seep around or through the primary sanitary pad. The panty includes a secondary absorbent positioned in the crotch area and extending into the body of the disposable panty, front and back, and preferably over the leg elastics to trap, inside the panty, leakage from the primary absorbent, and to prevent strike through onto e.g. outer clothing and bed linen.

  • Patent number: 8585669
    Abstract: An absorbent article, in particular a diaper. The rear portion thereof includes a pair of elastic side panels attached to opposing longitudinal edges thereof. The front portion of the article includes at least two landing zones upon which the elastic side panels overlap when the article is fastened. An area of the front portion located at least around each landing zone includes a plurality of first indicia in a first pattern. Each of said elastic side panels also includes a plurality of second indicia in a second pattern. The distance between adjacent second indicia including the second pattern increases as the elastic side panel is stretched. When the elastic side panels are stretched by a predetermined force, the second pattern on the elastic side panels matches the first pattern around each landing zone.

  • Patent number: 8568552
    Abstract: In an outer covering sheet of an absorbent product, first, second and third adhesive layer elements each extending in a left-right direction are formed on a second covering sheet by spiral spray application. Each of these adhesive layer elements has wide width parts and narrow width parts which are continuous with the wide width parts, respectively. Therefore, hot melt adhesive can be stably discharged across the entire length of the adhesive layer element, unlike in the case where only wide width parts are formed intermittently. As a result, it is possible to obtain the outer covering sheet which is a sheet member having the adhesive layer elements with desired shapes where unevenness is decreased. In the absorbent product which is manufactured with use of the sheet member, the comfort level of the wearer can be prevented from decreasing due to unevenness of thickness of the adhesive layer elements.

  • Patent number: 8568382
    Abstract: Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The backsheet has a physical variation along at least one axis, wherein said physical variation defines a first backsheet zone and a second backsheet zone, and at least one elastomeric element having at least one primary direction of stretch, said elastomeric element at least partially overlapping and joined to first and/or second backsheet zone, wherein a relaxed pathlength of said elastomeric element in the primary direction of stretch is less than a total pathlength of said backsheet in the region of overlap. The physical variation is a measurable difference as measured by a physical property selected from the group consisting of basis weight, thickness, density and tensile modulus.

  • Patent number: 8551064
    Abstract: A disposable absorbent article comprising an absorbent assembly comprising an absorbent core. The chassis may also comprise a water-impermeable backsheet and laterally opposing side flaps. Each of the side flaps may have a longitudinally extending first elastic gathering member attached at or adjacent to its proximal edge. The chassis may also comprise a second elastic gathering member attached at or adjacent the side edge of the chassis. The chassis may further comprise a first activation pattern in the front waist region and/or the back waist region, but the crotch region of the chassis may not be activated or may, alternatively, comprise a second activation pattern which is different from the first activation pattern. The article may further comprise at least one abdominal stretch panel attached to the interior surface or the exterior surface of the chassis in the front waist region or the back waist region.

  • 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.

  • Publication number: 20130226127
    Abstract: In a disposable diaper in a developed state where a front cover sheet and a rear cover sheet are separated from each other to be developed, as distance in a left-right direction from an absorbent body increases, a lower edge of the rear cover sheet goes away from an upper edge of the rear cover sheet and then goes toward the upper edge. A leg elastic member is bonded on the rear cover sheet along its lower edge, in left and right of the absorbent body. As above, the lower end portion of the rear cover sheet is convex downward in each of left and right of the absorbent body, and lower portions of hips of a wearer are wrapped with the lower end portions. It is therefore possible to suppress leakage of excrement from the lower portions of hips of the wearer.

    Abstract: An absorbent article includes a chassis, an absorbent structure placed on the chassis and elastic elements attached under tension to the chassis so as to extend across an absorbent structure region of the chassis occupied by the absorbent structure and to extend outward beyond opposite side edges of the absorbent structure. An elongation percentage of the elastic elements 6 is relatively low in the absorbent structure region as well as in first side regions outside opposite side edges of the absorbent structure and the elongation percentage is relatively high in second side regions outside the first side region and gradually increases as the elastic elements draw away from the first side regions toward the second side regions.
