  • Publication number: 20180177648
    Abstract: An absorbent article comprises a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the chassis having a body-facing surface and an outer-facing surface. The article also comprises a pair of side flaps comprising a first surface, a second surface opposite the first surface, and a first adhesive. The side flaps have a proximal end and a free distal end wherein each distal end is foldable around an edge of an undergarment when applied on the undergarment during use to attach the first adhesive to the underside of the undergarment thereby attaching the absorbent article to the undergarment.

  • Patent number: 8721610
    Abstract: A disposable pull-on garment has a front waist region and a back waist region opposite the front waist region. The disposable pull-on garment also has a chassis and front and back waist members attached to the chassis in the front and back waist regions, respectively. The front waist member has a first retraction force and the back waist member has a second retraction force. The disposable pull-on garment also has a pair of side members attaching the front waist region to the back waist region, thereby forming a waist opening and a pair of leg openings. Each of the pair of side members includes a waist zone and a hip zone. The waist zones have retraction forces which are about equal to the first retraction force, and the hip zones have retraction forces which are greater than the first or second retraction forces.

  • Patent number: 8632516
    Abstract: Disposable pant like garments are disclosed. Pant like garments of the present invention generally comprise a main absorbent portion and a pair of side portions. One or more sections of the pant-like garments are provided with one or more cohesive areas which allow for cohesive fastening and refastening of portions of the garment. The cohesives chosen may have the same properties or may be of the selective adhesive type. Pant like garments may be provided with cohesive fasteners and not other types of refastening means. In other variations, cohesive fasteners may be supplemented with one or more frangible bonds. Also disclosed are side portions having cohesive areas which may be converted in use from an abutting facing relationship to an overlapping facing relationship. Multiple cohesive areas of varying types for providing differential bond properties during use are also disclosed.

  • Publication number: 20120271265
    Abstract: A stretch laminate having enhanced features is disclosed. The laminate may include a first layer of nonwoven, a second layer of an elastomeric material, a third layer of a polyethylene and/or ductile polymeric film, and optionally, a fourth layer which may also be a nonwoven. The third layer may be bonded to the second layer in a pattern that includes bonded and unbonded areas. Following lamination the laminate may be activated to impart stretchability in a stretch direction. Activation causes plastic deformation/elongation of the third layer along the stretch direction, and upon elastic contraction of the second layer the deformed/elongated third layer gathers in the unbonded areas, creating desirable visual and tactile effects. The laminate has other advantages and may be provided with other features for enhancement of visual and/or tactile effects. The laminate may be used to form components of absorbent articles such as disposable diapers and training pants.
