  • Patent number: 6579275
    Abstract: A pant-like, disposable absorbent article includes an absorbent chassis, a pair of opposed side panels, at least one releasable joint and at least one folded fastenery. The absorbent chassis defines a pair of laterally opposed side edges and a pair of longitudinally opposed waist edges. The side panels extend between the side edges of the absorbent chassis to define a waist opening and a pair of leg openings in the pant-like disposable absorbent article. Each of the opposed side panels defines a first side margin which is permanently attached to the side edge of the absorbent chassis in one waist region of the absorbent article to provide a permanent joint. At least one of the opposed side panels further defines a second side margin opposite the first side margin which is releasably attached to the side edge of the absorbent chassis in the other waist region of the absorbent article to provide a releasable joint.

    Abstract: A disposable garment includes a chassis defining openings for the legs and waist of a wearer and side panels. The side panels include a targeted elastic material including zones of high and low elastic tension in the same material, integrated during formation of the material. The targeted elastic material is positioned so that at least one high tension zone is aligned with the waist opening, thereby functioning as an elastic band without requiring a separately manufactured, attached elastic band. A spacer zone, comprising a low tension zone or a no tension zone, is positioned between the at least one high tension zone, which is aligned with the waist opening, and the waist end edge of the side panel.

  • Publication number: 20030100879
    Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants and the like, having elastomeric ear panels and a fastening system that provides the user with different options as to how the absorbent article may be fitted to and removed from the wearer. The absorbent articles allow the wearer to choose between conventional and pull-on diaper configurations, or combinations thereof, and properly and comfortably fit a large range of wearer sizes. Further, the absorbent articles can be pulled on and/or off as a pant. This feature is provided by the ear panels which maintain sufficient tension to hold the diaper on the wearer throughout the period of use without harming the wearer's skin, while providing enough stretch to allow the diaper to be pulled up or down over the wearer's hips. The fastening system is refastenable for convenience yet strong enough to maintain the diaper in a fastened configuration without becoming detached if the diaper is pulled on or off the wearer.

  • Patent number: 6534694
    Abstract: A method of securing an elastic band between two material layers which are at least partially defined by meltable material includes forming perforations in the elastic band, placing the elastic band between two material layers, and bonding the material layers to one another through the perforations by heat fusion, wherein the perforations in the elastic band are formed at the same time as the material layers are fused together (i.e., the formation of the perforations in the elastic band is directly followed by bonding together, through the perforations, portions of the material layers). An elastic band secured between two material layers for inclusion in articles of one-time use includes the use of material layers that are at least partially defined by meltable material and an elastic band having perforations formed therein. The material layers are positioned on opposite sides of the elastic band and are joined together by heat fusion.

    Abstract: A disposable diaper includes a backsheet comprising an elastic inner layer and an inelastic outer layer. The elastic inner layer, in a transversely stretched state, is joined to the inelastic outer layer at a plurality of intermittently disposed spots. The spots are lined up to form a series of imaginary lines disposed on a bias between the longitudinal and transverse directions of the disposable diaper. In each of areas between the spots, defined by a plurality of intersecting imaginary lines that pass through a plurality of the spots that are closely arranged in succession, the inelastic outer layer is free to separate from the elastic inner layer upon contraction (relaxation) of the elastic inner layer, and thereupon the outer layer forms a plurality of longitudinal pleats. The pleats, formed by relaxing the transversely stretched inner layer, are disposed in a direction that is substantially normal to the direction of stretching.

The first arcuate section includes at least one arcuate elastic thread, as does the second arcuate section. Those threads are spaced by a gap. A portion of the longitudinally oriented elastic threads on either side of the core is located closely adjacent a respective gap between the arcuate elastic threads to elasticize the leg openings.

    Abstract: A disposable absorbent article is provided which includes a substantially liquid-impermeable, stretchable outer cover, a liquid permeable, stretchable top surface, and an absorbent body located between the outer cover and the top surface. The stretchable top surface can further include a first zone and a second zone. The stretchable outer cover can be configured to provide a first level of elongation when subjected to a tensile force of 100 gmf per inch (per 2.54 cm) of width according to the Material Elongation and Deformation Tensile Test set forth herein, while the first zone provides a second level of elongation that is less than the first level of elongation.

  • Publication number: 20020165518
    Abstract: A convertible pant-like, prefastened, disposable absorbent article having a back waist region and a front waist region forming a waist opening and two leg regions each forming a leg opening. A ratio of an elastic tension of the back waist region to an elastic tension of each of the leg region is at least about 0.6. Thus, the convertible pant-like, prefastened disposable absorbent article of the present invention is effective in reducing undesired leakage when it is applied to the wearer in a manner similar to a conventional training pant rather than a conventional diaper article.

  • Patent number: 6443935
    Abstract: In a method and device for applying a thread to a moving substrate, a thread is continuously dispensed to a pick-up point adjacent to the point of contact of two rotating wheels (2, 3) that are inclined towards each other. The peripheries of the wheels have fingers (7) which hook the thread and move it to one side or the other as the wheels rotate, and then deposit the thread extended between the fingers 180° from the pick-up point. Long spaces between the fingers (7) on one wheel or the other make it possible to lay the thread longitudinally (8b) or in a long diagonal line instead of merely in a lateral zigzag pattern. The method and device may be used to make an absorbent article, such as a diaper.

    Abstract: The invention relates to methods of fabricating absorbent articles. In a method of the invention, a bodyside liner, an absorbent core, and an outer cover are joined to form an absorbent article web sausage. Leg cut-outs are cut on opposing sides of the web sausage, and a waist opening is cut in a central region of the web sausage. Adhesive is applied to one of (i) a waist piece material and (ii) the web sausage about the waist opening; and also to one of (iii) extensible leg cuff material and (iv) the web sausage adjacent the leg cut-outs. A waist piece is severed from waist piece material, and is placed. over the waist opening and secured to the web sausage. Leg cuffs are severed from the leg cuff material, and are placed over the leg cutouts and secured to the web sausage. The waist piece and leg cut-outs are preferably stretched to a dimension representing about 5% to about 95% of stretch-to-stop dimensions when bonded to the web sausage.
