Publication number: 20240000624Abstract: 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.Type: ApplicationFiled: June 27, 2023Publication date: January 4, 2024Inventors: Jeromy Thomas RAYCHECK, Keith Richard WILLHAUS, Jeffry ROSIAK, Jason Edward NAYLOR, Kumardipti CHATTERJEE, Brian Patrick SELLERS, Michael Devin LONG, Nicholas Alexander TAYLOR, Sally Lin KILBACAK

Publication number: 20240000627Abstract: 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.Type: ApplicationFiled: June 27, 2023Publication date: January 4, 2024Inventors: Keith Richard WILLHAUS, Jeromy Thomas RAYCHECK, Jeffry ROSIAK, Jason Edward NAYLOR, Kumardipti CHATTERJEE, Michael Devin LONG, Nicholas Alexander TAYLOR

Publication number: 20240000633Abstract: 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.Type: ApplicationFiled: June 27, 2023Publication date: January 4, 2024Inventors: Jeromy Thomas RAYCHECK, Keith Richard WILLHAUS, Jeffry ROSIAK, Jason Edward NAYLOR, Kumardipti CHATTERJEE, Michael Devin LONG, Nicholas Alexander TAYLOR

Publication number: 20240000630Abstract: 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.Type: ApplicationFiled: June 27, 2023Publication date: January 4, 2024Inventors: Keith Richard WILLHAUS, Jeromy Thomas RAYCHECK, Jeffry ROSIAK, Jason Edward NAYLOR, Kumardipti CHATTERJEE, Michael Devin LONG, Nicholas Alexander TAYLOR, Sally Lin KILBACAK, Andrew David SCHOLES
