  • Patent number: 10639216
    Abstract: A disposable diaper having front and rear augmented waistband zones having a specified size and stiffness is disclosed. For relatively thinner, less bulky diapers of currently marketed designs, providing augmented waistband zones is believed to reduce mental and physical effort for the caregiver in application of the diaper. The augmented waistband zones provide a robust-feeling structure proximate the waist edges, which the caregiver may grasp at front and rear to adjust the diaper on the wearer. Caregiver perception of a need to reach deeper into the diaper structure to grasp it at a thicker area to tug at it is believed to be reduced.

    Abstract: The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, diaper pants, each including a chassis connected with front and back elastic belts. As discussed in more detail below, opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. As discussed in more detail below, an elastic laminate may be formed by continuously bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. The elastic strands are then intermittently severed in light-bond regions of the elastic laminate. Adhesive on the laminate causes the severed elastic ends to retract or snap back from the light-bond regions at a relatively slower and/or controlled rate.

In respective sides inboard of the low stiffness sub-regions, the inner sheet, the front and rear outer sheets and the first sheet segments are respectively overlapped to form inner high stiffness sub-regions, and in respective sides outboard of the low stiffness sub-regions, the inner sheet, the second sheet segments and the first sheet segments are overlapped to form outer high stiffness sub-regions.

  • Patent number: 8968266
    Abstract: A sanitary undergarment, comprising a fabric body, a crotch portion, a waist opening, and a thigh opening, each comprising one or more layers made of a breathable leak-proof material for blocking flow of the body fluid through the fabric body. The sanitary undergarment generally comprises a boxer brief construction. The fabric body constitutes a front portion and a rear portion and blocks flow of the body fluid of the wearer outside the sanitary undergarment and prevents staining of the outer garment. The front portion covers a front part of a pelvic region of the wearer. The rear portion covers a rear part of the pelvic region of the wearer. The crotch portion covers a crotch region of the wearer and comprises one or more of a first layer and a second layer. The second layer prevents chafing at the inner thigh regions of the wearer.

  • Patent number: 8968505
    Abstract: A process of manufacturing a stretch composite is disclosed. The process comprises providing a polyolefin based substrate, providing a letterpress adhesive application system comprising a pattern roll and an applicator roll, and depositing a molten, non-adhesive, elastomeric composition onto the applicator roll. The process further comprises transferring only a portion of the elastomeric composition that is on the applicator roll, from the applicator roll to the pattern roll, by contacting the pattern roll with the elastomeric composition that is on the applicator roll, and transferring substantially all of the elastomeric composition from the pattern roll to the substrate, by contacting the substrate with the elastomeric composition that is on the pattern roll, without damaging the substrate.

  • Patent number: 8961487
    Abstract: A method of making an elastic composite is described that entails conveying a first sheet of material on a conveyor, and wrapping a section of elastic about the first sheet and the conveyor, thereby applying elastics cross directionally across the first sheets. A second sheet of material is applied onto the first sheet having elastics applied thereon, thereby creating a subcomposite including the first sheet, the second sheet, and elastics sandwiched therebetween, wherein a plurality of elastics extend outward from the one side of the subcomposite, about the conveyor, and return into an opposite side of the subcomposite.

  • Publication number: 20150051566
    Abstract: The purpose of the present disclosure is to provide an absorbent article that can be made smaller because the crown section continues to fit the wearer's excretory opening, which has a complex shape, both when dry before absorbing menstrual blood and when wet after absorbing menstrual blood, and with which leakage does not occur easily. This absorbent article is as follows: The absorbent article (1), which comprises a liquid-permeable top sheet (4), a liquid-impermeable back sheet, and a specified absorbent (7) between the liquid permeable top sheet (4) and the liquid-impermeable back sheet, is characterized in that: the absorbent article (1) has a crown section (2), which protrudes in the thickness direction of the absorbent article (1) in the region that is in contact with the excretory opening and comprises a specified cushion section; and in the central section, the crown section (2) has a compression workload (WC) of 10-50 (N·m/m2) and a compression resilience (RC) of 35-100%.

  • Patent number: 8951239
    Abstract: A disposable diaper has an absorbent body, an outer covering sheet and two end holding sheets, and both end portions of the absorbent body are fixed between the end holding sheets and the outer covering sheet. Since a turndown portion of an upper end portion of the end holding sheet is bonded on an upper end portion of a first covering sheet, a waist covering portion has structure where the first covering sheet is laminated on the two-layered end holding sheet. Therefore, a thickness of the outer covering sheet can be reduced, while maintaining strength of the waist covering portion by appropriately selecting material of the end holding sheet, thereby to easily improve softness of the disposable diaper. Since an upper end of a second covering sheet is positioned below the turndown portion, softness and breathability in an area between the turndown portion and the second covering sheet is increased.
