  • Patent number: 10265223
    Abstract: A textured laminate structure and absorbent articles having a component formed of the textured laminate structure are disclosed. The textured laminate structure may have a first layer formed of a nonwoven web having a preexisting pattern of first apertures therethrough, a second layer, and one or more elastic members disposed between the first and second layers in a prestrained condition. The laminate structure may be discontinuously joined or bonded such that the first layer is joined or bonded to the structure in first portions and unjoined or unbonded to the structure in second portions. The structure provides a stretch laminate with tactilely and visually interesting features, and may be used to form components of a disposable absorbent article such as a side panel thereof.

  • Patent number: 10159610
    Abstract: An absorbent article (10, 110) can include a waist containment member (54) with a first longitudinal side edge (72), a second longitudinal side edge (74), a proximal portion (76), an intermediate portion (77), and a distal portion (78). The proximal portion (76) can be coupled to the chassis (11) of the absorbent article (10, 110). The intermediate portion (77) can be free to move independent of the proximal portion (76) and the distal portion (78) and free to move independent of the body facing surface (19) of the chassis (11) to provide a containment pocket (82) for containing body exudates. The distal portion (78) can be disposed underneath the intermediate portion (77) when the absorbent article (10, 110) is in the stretched, laid-flat configuration. The waist containment member (54) can also include a first lateral tack-down region (83a) and a second lateral tack-down region (83b).
