Definitions

  • the present disclosure relates to absorbent articles, and more particularly, to absorbent articles having front and/or back waist regions including one or more frangible pathways with opening facilitation features.
  • Some absorbent articles have components that include elastomeric laminates.
  • Such elastomeric laminates may include an elastic material bonded to one or more nonwovens.
  • the elastic material may include an elastic film and/or elastic strands.
  • a plurality of elastic strands are joined to a nonwoven while the plurality of strands are in a stretched condition so that when the elastic strands relax, the nonwoven gathers, and in turn, forms corrugations and rugosities.
  • the resulting elastomeric laminate is stretchable to the extent that the corrugations allow the elastic strands to elongate.
  • Absorbent articles in the form of diaper pants may also be configured with an absorbent chassis connected with front and back elastic belts, wherein opposing end regions of the front and back belts are connected with each other at side seams.
  • the elasticity of the front and back belts is removed in regions where the chassis connects with the belts.
  • stretched elastic strands are glued between two continuous nonwoven webs to form an elastic laminate. Regions of the elastic strands may then be intermittently deactivated along the length of the elastic laminate by cutting the elastic strands in areas to be connected with the chassis, sometimes referred to as tummy elastic cutting.
  • Some caregivers of older incontinent babies or toddlers may prefer a closed, pant-style disposable absorbent article to enable application to, and removal from, a child while the child is in a standing position.
  • One disadvantage of this product form is that the removal and disposal of feces-containing products may be unhygienic and inconvenient. For example, pulling the product down could cause feces to smear down the legs of a user.
  • a caregiver may tear open the bonded sides using force. In turn, the force used can lead to a rapid release of energy from the diaper, causing the caregiver to lose control of the product and allowing feces to spill out.
  • some diaper pants may be configured with tear lines in the front belt or back belt.
  • tear lines may include perforations that allow a caregiver to more easily separate the belt along the perforation lines. Once the belt is separated, the diaper pant can be more easily removed from the wearer without having to slide the diaper pant down the wearer's legs, in a similar manner as a traditional open taped diaper form.
  • tear lines may be utilized relatively more effectively when a caregiver initiates the tearing process in a certain location and/or in a correct tearing direction in accordance with the design intent. If a caregiver cannot readily identify a starting location of the tearing process and/or the intended direction of the tearing process, then difficulties experienced by the caregiver in successfully and easily removing a diaper pant from a wearer may be exacerbated.
  • pant-style articles that provide the caregiver the ability to remove and dispose soiled products in a similar manner to traditional open diaper forms.
  • opening facilitation features such as opening operational indicia and/or opening mechanical aids, to help a caregiver successfully determine the location and function of the frangible pathway, and successfully complete the pant opening and disposal operation.
