  • Publication number: 20240000624
    Abstract: The present disclosure relates to absorbent articles comprise a first belt and a second belt with frangible pathways. An accessibility opening may also be positioned in the first and/or second belt, and a fastener component may be connected with the belt adjacent the accessibility opening. Such frangible pathway configurations provide a feature that allows an elastic belt of a diaper pant to be relatively easily torn along the frangible pathway when removing the diaper pant from a wearer, and the fastener component may provide a feature that helps maintain a used diaper pant in a disposal configuration. An absorbent article may also comprise opening facilitation features, such as opening operational indicia and opening mechanical aids, and combinations thereof. Such opening facilitation features may help a user to successfully determine the location and/or function of the fastener component and frangible pathway and/or successfully complete pant opening operations.

  • Publication number: 20240000627
    Abstract: The present disclosure relates to diaper pants having a first belt and a second belt with one or more frangible pathways. A frangible pathway may extend between inner edge and outer edges of a belt. A grip region comprising an accessibility opening may be positioned between the inner and outer edges of the belt. The frangible pathway may comprise a first tear zone and a second tear zone extending from the accessibility opening to a distal terminus and to a proximal terminus. Such frangible pathway configurations provide a feature that allows a belt of a diaper pant to be relatively easily torn along the frangible pathway. Once torn along the frangible pathway, the diaper pant may be removed from a wearer and rolled up for disposal. A fastener component may be connected with another portion of the diaper pant to help maintain the diaper pant in a disposal configuration.

  • Publication number: 20240000633
    Abstract: The present disclosure relates to absorbent articles comprising a first belt and a second belt, comprising one or more frangible pathways. A fastener component may be positioned on the inner wearer facing surface of the first belt and/or second belt, and an accessibility opening in the first belt and/or the second belt may be positioned adjacent the fastener component and the inner edge of the first belt and/or the second belt. Positioning fastener components on the inner wearing facing surface of the first belt and/or the second belt helps to conceal the fastener component from the wearer while wearing the diaper pant. Positioning the accessibility opening adjacent the fastener component may help a caregiver successfully determine the location of and access such hidden disposal fastener components. An absorbent article may also comprise opening facilitation features to help a user to successfully determine the location and/or function of the fastener component.

  • Publication number: 20240000630
    Abstract: The present disclosure relates to absorbent articles having a first belt and a second belt with one or more frangible pathways. A frangible pathway may extend between a proximal terminus on an inner edge of a belt and a distal terminus on an outer edge of the belt. A grip region comprising an accessibility opening may be positioned between the inner and outer edges of the belt. The frangible pathway may comprise a first tear zone and a second tear zone extending from the accessibility opening to the distal terminus and to the proximal terminus. Such frangible pathway configurations provide a feature that allows a belt of a diaper pant to be relatively easily torn along the frangible pathway when removing the diaper pant from a wearer. The frangible pathway may be configured to allow a caregiver to initiate and/or completely tear the first belt with one hand.

  • Patent number: 11679039
    Abstract: Methods of forming front and back waist gasketing elements on an absorbent article are provided. The methods include the steps of providing a web of chassis material and waist gasketing elements, each having a first transverse edge, a second transverse edge, a top and bottom layer. The methods further include bonding the top and bottom layers in closure bond regions, and joining the waist gasketing elements to the chassis to form a strip of final articles. The methods include dividing the strip of final articles between the first and second transverse edges such that a cut separates two final articles, a leading article and a trailing article, wherein each cut is disposed within a closure bond region, forms a back waist edge of the leading article and a front waist edge of the trailing article; and forms an outboard lateral edge of a back waist gasketing element on the leading article and an outboard lateral edge of a front waist gasketing element on the trailing article.
