  • Patent number: 8664469
    Abstract: A disposable absorbent article has front and back panels, each having an elastic film layer and each having first and second zones. The first zone of each panel is extensible and retractable and the second zone of each panel is non-extensible and non-retractable. Each of the front and back panels has first and second side edges. An absorbent assembly is secured to the front and back panels. The absorbent assembly has a first end secured to the second zone of the front panel and a second end secured to the second zone of the back panel.

  • Patent number: 8617131
    Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants and the like, having elastomeric flaps and a fastening system that provides the user with options as to how the absorbent article may be fitted to and removed from the wearer. 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: 8496638
    Abstract: Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the absorbent articles have a waistband that encompasses a pair of opposing side panels and a waist region of the article. The side panels are attached to longitudinal edges of a chassis and are configured to extend around a person's waist. The side panels are attached to fastening devices for fastening the absorbent article to a wearer. In accordance with the present invention, the side panels and the waist region are both elastic. In order to improve fit and comfort, the stretch properties of the side panels are matched with the stretch properties of the waist region. For example, elongation of the side panels can be matched to elongation of the waist region or, alternatively, displacement of the side panels can be matched to the displacement of the waist region for a given range of forces.

In addition, an absorbent garment has a continuous liquid permeable layer.

  • Patent number: 8246593
    Abstract: An absorbent article providing improved body fit. The absorbent article includes an extensible fluid permeable facing layer and a first absorbent layer joined to the facing layer. The first absorbent layer includes zones of extensibility. Each zone of extensibility is a region of the first absorbent layer of relatively higher extensibility than regions of first absorbent layer adjacent to the zone of extensibility. A liquid impermeable backsheet is joined to the facing layer at the periphery. The liquid impermeable backsheet has a garment facing surface. A fastening means is disposed on at least a portion of the garment facing surface of the liquid impermeable backsheet. The fastening means defines attachment zones. At least a portion of the first absorbent layer is decoupled from the attachment zones of the fluid impermeable backsheet.

  • Patent number: 8226624
    Abstract: Various garments are disclosed which include a body adhesive for attaching the garment to the skin of a wearer. More particularly, the garment can include at least one extensible portion. An adhesive member comprising an adhesive layer and a cover member may be positioned over the extensible portion. The cover member may completely cover the adhesive layer when the extensible portion is in a relaxed condition. When the extensible portion is stretched, however, the cover member may define openings that expose the adhesive layer for adhering the adhesive to a wearer. The garment may comprise, for instance, a diaper, a training pant, a swim pant, a hospital gown, an industrial garment, a glove, a feminine hygiene product, an adult incontinence product, and the like. The adhesive member can be positioned over any suitable extensible portion on the garment.
