  • Patent number: 10653568
    Abstract: A disposable pull-on diaper that keeps in close contact with a wearer's crotch region includes a lower torso cover and an absorbent chassis. The absorbent chassis has a front end portion overlapping a front waist region of the lower torso cover and a front end portion of the front end portion is joined to an elastic region in the lower torso cover. A front end adjoining portion of the front end portion is not joined to the elastic region. An area in the absorbent chassis being adjacent the front end adjoining portion on the side of the crotch region is joined to an inelastic region defined on the side closer to the crotch region than to the elastic region. The absorbent body contained in the absorbent chassis extends at least from the crotch region to the front end adjoining portion. The front end portion in the front end portion of the absorbent chassis is defined by a portion of the cover sheet wrapping the absorbent body which extends outward beyond the absorbent body.

    Abstract: A topsheet layer material for use on an absorbent article includes a longitudinal direction, a transverse direction and a depth direction and comprises a planar sheet. The topsheet layer material includes visually and spatially coordinated embossed channels and apertures. The embossed channels are curvilinear indentations configured along either the longitudinal, the transverse direction, or a combination of longitudinal and transverse directions. The apertures are positioned along the topsheet layer material laterally adjacent to the channels such that at least a portion of the apertures have an overall shape configuration that is substantially similar or the same as at least a portion of the shape of the embossed channel. Such coordinated aperture configuration may also be generally concentric with or generally parallel to the embossed channels.

  • Patent number: 8834441
    Abstract: An undergarment, such as a diaper, includes a hidden central core pocket for receipt of an absorbent pad. The pocket is formed between an inner, fluid permeable layer and a fluid isolation layer. The fluid isolation layer is attached to the inner or anchor layer and is located between the inner layer and an outer layer to which the inner layer is attached. The pocket is narrower than the outer to isolate fluids from edges of the outer layer and from diaper leg openings. Both the fluid isolation layer and the outer layer may be fluid resistant to provide additional protection against leakage. Adjustment fasteners on the outside of the outer shell permit size adjustment for the diaper and the adjustment fasteners are positioned within the periphery of the pocket so that presence of the absorbent pad will enhance comfort.

  • Patent number: 8777915
    Abstract: A reusable diaper may include an inner layer to wick moisture and an outer layer substantially impervious to liquids. A waist portion may include a corner region for securing the diaper in a desired position. The corner region may be resiliently stretchable and substantially impervious to liquids, and may include first and second layers coupled to the respective inner and outer layers. The coupled first layer and inner layer define a first seam allowance, and the coupled second layer and outer layer define a second seam allowance. The first and second seam allowances may be positioned within the corner region to help inhibit wicking of liquid through the seam allowances into the corner region. And a fluid-resistant region may be provided to help resist wicking of moisture through the inner layer past the fluid-resistant region.
