    Abstract: A disposable diaper has front and rear waist regions, a crotch region, and an absorbent chassis. The absorbent chassis includes an absorbent structure and a pair of side flaps. Each of the side flaps has layered sheet materials and includes a distal edge, a cuff branch line between the side edge of the absorbent structure and the distal edge, a leg-opening elasticized area between the cuff branch line and the distal edge, and a leakage-barrier cuff branched from the cuff branch line and intersecting with the leg-opening elasticized area. The leakage-barrier cuff has a free edge parallelly-spaced from the cuff branch line. The distance from the cuff branch line to the distal edge is larger than from the cuff branch line to the free edge. The number of sheet material layers included in the leg-opening elasticized area is larger than in the leakage-barrier cuff.

    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.

    Abstract: A disposable diaper 10 has sheet-like leg hole stretch units 100 that extend in a product lengthwise direction L in an area where leg hole concave units 35 are formed and are at least partially stretchable along a product lengthwise direction L. End edges in a product widthwise direction W of the leg hole stretch units 100 meander in the product lengthwise direction L. Distances between the end edges in the product widthwise direction W of the leg hole stretch units 100 and a center line CL change from a front waistline unit 20 toward a rear waistline unit 30. Provided are a plurality of inflection points where an amount of change in the distance starts decreasing instead of increasing and a plurality of inflection points where an amount of change in the distance starts increasing instead of decreasing, respectively.

  • Patent number: 8920400
    Abstract: A disposable absorbent garment includes a body chassis having a terminal front waist edge, a terminal back waist edge longitudinally spaced from the terminal front waist edge, a first length defined between the terminal front waist edge and the terminal back waist edge, and a laterally extending centerline defined half way between the terminal front and back waist edges. An absorbent insert is fixedly secured to the body chassis. The absorbent insert has a retention region including an absorbent material. The retention region has first and second longitudinally spaced boundaries and a second length defined between the first and second boundaries. The second length is less than or equal to 50% of the first length, and at least 70% of the second length is positioned between the centerline and the terminal front waist edge. There is no absorbent material disposed outside of the retention region defined between the first and second boundaries.

  • Patent number: 8915899
    Abstract: An absorbent article includes a body side liner, a back sheet, an absorbent body positioned between the body side liner and the back sheet, and a body conforming structure positioned in direct facing relation with the body side liner. The body conforming structure length is at least 50% the absorbent body length and is aligned with a longitudinal centerline of the absorbent article. The median anterior portion width of the body conforming structure is greater than the median central portion width of the body conforming structure which is greater than the median posterior portion width of the body conforming structure. The anterior portion includes a well, the central portion includes a channel, and the posterior portion includes a taper. The well transitions into the channel via a first convex transition and a concave transition. The channel transitions into the taper via a second convex transition.

  • Patent number: 8864734
    Abstract: The present invention provides a disposable pants-type wearing article free from possibility that upper regions of the leg-openings' peripheral edges might be formed with frills even when the belt-like leg elastic members contract along the peripheral edges of the respective leg-openings. Belt-like leg elastic members in a disposable pants-type diaper each has inner and outer surfaces at least one of which is bonded to sheet-like members included in put flat and joined together regions and a crotch region of the diaper. The belt-like leg elastic members extend from the respective put flat and joined regions along leg-openings' peripheral edges. Over ranges in which the belt-like leg elastic members extend along the respective peripheral edges the sheet-like members also extend along the peripheral edges.
