Abstract

An absorbent article includes at least one multilayered containment barrier which is configured to inhibit the flow of body exudates along the surface of the absorbent article. The containment barrier includes multiple layers of material. Each of the layers defines an inner edge which remains at least partially unattached to the other layers to allow the body exudates to flow into an area between the layers in use for improved containment and absorption of exudates. In a particular embodiment, the absorbent article may include a pair of such containment barriers which are laterally spaced apart to provide a void space between the wearer's buttocks and the surface of the absorbent article for containing body exudates. In such a configuration, the absorbent article may further include a pair of longitudinally extending containment flaps located on the side edges of the article laterally outwards from the containment barriers for improved containment Alternatively, the containment barriers may be located between the topsheet layer and absorbent body of the absorbent article. In such a configuration, the topsheet layer defines an opening which is located at least partially over the containment barriers to receive fecal exudates.

  1. 1. A disposable absorbent article having a front waist section, a rear waist section, an intermediate section which interconnects said front and rear waist sections, a pair of longitudinally opposed end edges, and a pair of laterally opposed side edges, said article comprising at least one multilayered containment barrier which is located adjacent one of said edges of said absorbent article to inhibit the flow of body exudates and which comprises at least three layers of material configured in a facing relationship with each other and extending in a parallel relationship with a bodyfacing surface of said article in use wherein each of said layers defines an outer edge which is attached to said other layers and a free edge which remains at least partially unattached to said other layers to allow said body exudates to flow into an area between said layers in use.
  2. 10. A disposable absorbent article having a front waist section, a rear waist section, an intermediate section which interconnects said front and rear waist sections, a pair of longitudinally opposed end edges, and a pair of laterally opposed side edges, said article comprising:a) a backsheet layer;b) a liquid permeable topsheet layer which is connected in superposed relation to said backsheet layer;c) an absorbent body which is located between said topsheet layer and said backsheet layer, andd) a pair of longitudinally extending, multilayered containment barriers which are located in a laterally spaced apart relation on said topsheet layer of said absorbent article and which are configured to provide a void space between a wearer's buttocks and said topsheet layer of said absorbent article for containing body exudates wherein each of said containment barriers includes at least 3 layers of material configured in a facing relationship with each other and extending in a parallel relationship with a bodyfacing surface of said article in use and wherein each of said layers of said containment barrier defines an outer edge which is attached to said other layers of said containment barrier and an inner edge which remains at least partially unattached to said other layers of said containment barrier to allow said body exudates to flow into an area between said layers of said containment barrier in use.
