  • Publication number: 20040193134
    Abstract: The invention relates to absorbent articles, such as diapers, training pants, adult incontinence articles, feminine protection articles and the like having a specific anal or vaginal cuff with an opening, which is sag-tolerable. The articles have a specific construction of a core, backsheet and the cuff, which each have specific dimension, in relation to one another. Preferred is for example that that the cuff has elasticated regions along the opening and that the cuff is (non-elastically) extendible is transverse direction, having for example longitudinal folds which easily unfold and extend the cuff in transverse direction, ensuring the cuff does not sag when the backsheet and care sack due to soiling.

  • Patent number: 6482191
    Abstract: An absorbent article having a void space for receiving bodily exudates comprises an elongate slit opening in communication with the void space. The elongate slit opening includes elasticated region disposed along longitudinal side edges of the slit opening which maintain longitudinal and lateral alignment and Z-direction proximity with a point of discharge on a wearer during use. The elasticated regions contain stored elastic energy producing tensile forces which are distributed laterally away from the slit opening enabling the edges to deflect and allow bodily exudates to pass through the slit opening to the void space.
