  • Patent number: 11969322
    Abstract: An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

  • Patent number: 9956122
    Abstract: A method of manufacturing a liner/composite web for use in an absorbent article includes joining a leg elastic member to a web moving in a machine direction and joining a flap elastic member to the web. The flap elastic member is spaced from the leg elastic member. The web is folded to form a leg and flap elastics composite including an outer side edge. The web is joined to a substrate to form the liner/composite web. The liner/composite web is joined to a web of material such that the outer side edge of the leg and flap elastics composite is coterminous with one of a pair of laterally opposing side edges of the web of material.

  • Patent number: 9089454
    Abstract: Absorbent articles are disclosed having extended waistbands. More particularly, the absorbent articles include a back waistband and/or a front waistband that encircle a portion of the circumference of the waist opening. The absorbent article includes a front portion attached to a back portion by a pair of stretchable side areas. Each of the side areas are made from at least two panels that are connected together along a vertical attachment area. In accordance with the present disclosure, a waistband is incorporated into the article that extends over the entire front portion or the entire back portion and terminates at opposite ends on opposing side areas. Each end of the waistband, however, terminates prior to the vertical attachment areas leaving a gap in between. The presence of the gap has been found to provide various benefits and advantages including improved stretch properties for donning the article.

  • Patent number: 9018434
    Abstract: Absorbent articles are disclosed that have been printed with active graphics alone or in combination with permanent graphics to create a wetness indicator. Different active graphic compositions and/or permanent graphic compositions are combined so as to make the wetness indicator very prominent on the article. In addition, when the absorbent article is wetted, the active graphics undergo a change that is easily noticed by the wearer or the caregiver for the wearer. In one embodiment, for instance, active graphics are positioned within a distinctive frame. The frame focuses a person's attention onto the active graphics. The active graphics fill most of the surface area of the frame such that when the absorbent article is wetted, a clearly noticeable change occurs.

  • Patent number: 8956493
    Abstract: A method of manufacturing a leg and flap elastics composite for use in an absorbent article includes joining a leg elastic member to a web moving in a machine direction. A flap elastic member is joined to the web and spaced from the leg elastic member. The web is fed to a chopper assembly wherein portions of the leg and flap elastic members are rendered less elastic at spaced-apart intervals to define deadened portions of the leg and flap elastic members.
