  • Publication number: 20230381033
    Abstract: A disposable absorbent article having a topsheet, a backsheet, and an absorbent core structure therebetween. The absorbent core structure having an upper nonwoven layer, a lower nonwoven layer, and a portion of an inner core layer disposed therebetween. The portion of the inner core layer is contained within the upper and lower nonwoven layers by sealing a portion of the first and second side regions of the upper nonwoven layer with a portion of the first and second side regions of the lower nonwoven layer at a lateral perimeter seal. An adhesive is positioned between the upper and nonwoven layers in the perimeter seal. The lateral perimeter seal is positioned in the middle region and has a longitudinal seal length that is from about 45% to about 90% of the longitudinal inner core length.

  • Publication number: 20220133555
    Abstract: An absorbent structure is disclosed, which may be or form part of an absorbent core of an absorbent article. The structure has a caliper, a fluid-receiving side and a non-receiving side. The non-receiving side occupies a first x-y plane; the receiving side occupies a second x-y plane. The structure has a first zone constituting a first portion of the caliper proximate the non-receiving side, and a second zone constituting a second portion of the caliper proximate the receiving side. Each of the zones includes a co-formed blend of constituents. The blend may include AGM particles, spun filaments and/or cellulose fibers. In examples including AGM particles, particles in the first zone may have an average particle size smaller than that of particles in the second zone. In examples including filaments, filaments in the first zone may have an average filament size smaller than that of the filaments in the second zone.

  • Patent number: 8402809
    Abstract: A method and apparatus for determining the work required to expel a tampon from a tampon applicator having a barrel containing the tampon and a plunger for expelling the tampon from the barrel. The method includes the steps of selecting and applying an applicator gripping test force to a grip zone on the barrel of the tampon applicator and selecting a tampon expulsion test rate and applying a force to the plunger sufficient to expel the tampon from the barrel of the tampon applicator at the selected tampon expulsion test rate. Further, the method includes the step of calculating the force on the plunger required to expel the tampon from the barrel at the selected tampon expulsion test rate as a function of the distance the tampon travels during expulsion.

  • Patent number: 8220651
    Abstract: A container including a support structure defined by a side wall portion and a bottom wall portion. An upper portion is integrally attached to the support structure, where the upper portion is formed of a flexible material defining opposing portions. The flexible material has a lower stiffness than a stiffness of the side wall portion, and the opposing portions are movable between a closed position located in engagement with each other and an open position where the opposing portions are separated from each other defining an opening to an interior area of the container. A frangible portion is provided on the upper portion forming a predefined separation line for separating at least a portion of the upper portion from the support structure.

  • Patent number: 7799005
    Abstract: A method is provided for measuring the insertion distance of an intravaginal article within a human vaginal cavity. The method uses a measuring device, which can be slidably attached to a withdrawal means of a vaginally inserted intravaginal article. The measuring device may be moved along the withdrawal means to a predetermined position, and then fixedly secured to the withdrawal means. The intravaginal article is then removed from the vaginal cavity and the insertion distance determined.
