  • Patent number: 7727211
    Abstract: Absorbent articles such as diapers, incontinent briefs, training pants, diaper holders and liners, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent article includes an absorbent core designed so as to retain low levels of fluid in the crotch region, relative to the other core regions, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear ends of the article. The absorbent core has a non-removable absorbent core component in the crotch region and removable absorbent core components in the front or rear regions of the article.

  • Patent number: 7727212
    Abstract: An absorbent article worn in the groin area, in which, when a compressive force is received from a lateral direction, a main absorbent region can oppose an excretion area of a wearer's body without twists or wrinkles occurring, and when the compressive force is relaxed, the article easily recovers to its original shape. An absorbent body provided in the absorbent article has a main absorbent region, reinforcing regions, and buffer regions. The bending stiffness of the reinforcing regions and the main absorbent region is larger than that of the buffer regions. When compressive force is received from a wearer's thigh areas in the lateral direction, the reinforcing regions that are positioned to the left and right deform in a curved shape, and the buffer regions that are to the left and right are compressed. The main absorbent region does not easily deform, and maintains a tight fit.

  • Publication number: 20100125263
    Abstract: A disposable absorbent article includes two laterally opposing longitudinally extending barrier cuff strips attached to an absorbent assembly in laterally opposing attachment zones. Each barrier cuff strip includes an upper layer and a lower layer at least between its proximal edge and the attachment zones. A longitudinally extending elastic gathering member is attached to each barrier cuff strip adjacent to its proximal edge. When the article is worn, the elastic gathering members contract and raise the barrier cuff strips to form side barriers. The absorbent assembly includes an absorbent core that may contain superabsorbent particles, which may be contained inside pockets. A portion of the absorbent assembly such as the portion that lies between the barrier cuff strip attachment zones may be extensible and may include a water-impermeable layer. The laterally opposing attachment zones may act as dams preventing a lateral flow of liquid bodily waste.

  • Publication number: 20090131852
    Abstract: This invention relates to a sanitary product for use by women for the absorption of menstrual fluid and such like. The product comprises a plug and a pad joined by a sheath. The plug is substantially cylindrical so that is fits comfortably in a vaginal cavity. The pad remains outside the vaginal cavity, but has an absorbent layer on an inward side proximal to the plug and a liquid impermeable layer on an outward side. In use, a wearer can insert a finger into the sheath from the outward side of the pad assist with insertion of the plug into the vaginal cavity. A string is provided that extends inside the sheath from the outward end of the plug to aid removal of the product. A line of weakness extends along the major axis of the pad, about which the pad is disposed to fold in use. This encourages the pad to fold around the plug to accommodate the plug during removal of the product, thus improving hygiene.

  • Patent number: 7329243
    Abstract: An inter-labial pad which can be inserted easily to a point of insertion is provided. An inter-labial pad 1 having an absorbent body for absorbing a body fluid is covered with a cover sheet, wherein a top portion 10 to be in contact with the depth of labia when the inter-labial pad 1 is put between the labia is provided. The top portion 10 has a shape different between the forward end 10a coming in contact with the forward of the labia and the backward end 10b coming in contact with the backward of the labia upon attachment, with the backward end being in a sharp shape and of narrow width and sharp angle. Thus, the inter-labial pad 1 can be inserted easily from a sharp backward end 10b easily to the labia.

  • Patent number: 7329244
    Abstract: A pull-on disposable diaper has a body fluid absorbing component folded inward in a transverse direction of the diaper so that a width of the body fluid absorbing component may be reduced in a crotch covering region. In vicinities of leg-holes, elastic members intersect transversely opposite side edges of the body fluid absorbing component above points X, Y at which the side edges of the body fluid absorbing component intersect folding guides.

  • Patent number: 7326193
    Abstract: A disposable pants-type wearing article includes a body fluid absorbent assembly. In a crotch region of the wearing article, transversely opposite side edges of the body fluid absorbent assembly are respectively formed with folded portions so that a non-folded portion extending in from of the folded portions may have a relatively small extent and a non-folded portion extending behind the folded portions may have a relatively large extent.

  • Publication number: 20070293832
    Abstract: Absorbent articles with waist seals are disclosed. The seals are formed from folded stacks, discrete segments, or pleated material arranged to provide a resiliently compressible seal that can be located at one or more locations within the absorbent article, e.g., along a central portion of the rear waist region of a diaper. The seals may be constructed from relatively thin materials that (through folding, stacking, pleating, etc.) can provide a resiliently compressible seal that is thick enough and appropriately shaped to conform to the wearer's anatomy well enough to provide the desired sealing. At the same, time, the continuous web material used to form the seal is preferably thin enough to be economically delivered to the manufacturing line in roll form.
