    Abstract: A compressed portion is formed in the absorbent article by compressing the absorber through a compression process. The compressed portion has a top-surface groove formed on the skin-contact-surface side, and a back-surface groove formed on the clothing-contact-surface side. A bottom portion of the top-surface groove is flat. Since the recessed portions are formed in the bottom portion of the back-surface groove through the compression process, a compression part where the density of the absorber is increased more than in an uncompressed portion and high compression parts where the density of the absorber is increased more than in the compression part are formed in the bottom portion. Thus, the absorbent article can be permeate into by a thick liquid, and is more likely to absorb liquid.

  • Patent number: 8847002
    Abstract: An absorbent article that contains a topsheet having embossed regions is provided. The embossed regions propagate in a longitudinal direction of the article in the form of a wave having one or more alternating crests (peaks) and troughs (valleys). Such a wave pattern helps slow down the flow of bodily fluid by directing it along a tortuous path defined by the densified edges rather than in a straight line. Among other things, this reduction in flow rate can help provide sufficient time for the absorbent core to absorb the fluid, which is particularly helpful when it is already partially filled with fluid. Nevertheless, bodily fluids can still sometimes pool near the crests and/or troughs and result in leakage. To help counteract this tendency, the present inventors have discovered that a plurality of apertures can be employed in the topsheet that are arranged in a column that generally extends in a longitudinal direction of the article.

  • Patent number: 8841507
    Abstract: An absorbent article having improved softness signals is disclosed. The article may include a topsheet or a backsheet including a nonwoven web. The web may have a basis weight of 30 gsm or less, may be formed of spunlaid fibers including polyolefin and up to 5 percent by weight TiO2, and may be impressed with a pattern of bond impressions to a bond area percentage of at least 10 percent forming a pattern of bonded regions and raised regions. The web may have opacity of 42 or greater; have an average height difference between bonded regions and raised regions of at least 280 ?m; be hydroengorged; and/or have a cross-direction tensile strength of 350 gf/cm. A nonwoven web manufactured to have a suitable combination of such features exhibits an enhanced appearance of softness, soft tactile feel and satisfactory mechanical attributes, while being relatively cost effective.

  • Patent number: 8834441
    Abstract: An undergarment, such as a diaper, includes a hidden central core pocket for receipt of an absorbent pad. The pocket is formed between an inner, fluid permeable layer and a fluid isolation layer. The fluid isolation layer is attached to the inner or anchor layer and is located between the inner layer and an outer layer to which the inner layer is attached. The pocket is narrower than the outer to isolate fluids from edges of the outer layer and from diaper leg openings. Both the fluid isolation layer and the outer layer may be fluid resistant to provide additional protection against leakage. Adjustment fasteners on the outside of the outer shell permit size adjustment for the diaper and the adjustment fasteners are positioned within the periphery of the pocket so that presence of the absorbent pad will enhance comfort.

  • Patent number: 8772570
    Abstract: A liquid-absorbent structure configured to prevent a liquid-absorbent core material from being unevenly distributed and thereby to assure that bodily fluids can be smoothly absorbed by the liquid-absorbent structure. According to one embodiment the present invention provides a panty liner that includes a topsheet lying on a side facing the wearer's body, a backsheet facing the wearer's garment and a liquid-absorbent structure sandwiched between these sheets. A first inner surface of a first sheet forming the liquid-absorbent structure is coated with adhesives to form a plurality of first bonding regions and a second inner surface of a second sheet is coated with adhesives to form a plurality of second bonding regions. Each of the first non-bonding regions lies between each pair of the first bonding regions, and each of the second non-bonding regions lies between each pair of the second bonding regions.

  • Patent number: 8764718
    Abstract: An absorbent article, especially an incontinence pad, having a length and a width extension, the length being greater than the width, and having absorbent core material, wherein the outer longitudinal edges of the absorbent material form three convex lobes (2, 3, 4), wherein a pair of folding lines (5) extend between the longitudinal ends of the middle one (3) of the three lobes (2, 3, 4), so as to divide the absorbent core material into a central portion (6) and a pair of longitudinal side portions (7), such that, when the article (1) is in use, the folding lines (5) are generally positioned so as to extend along the crotch area of the user, starting from the gracilis tendons and ending in the region of the perineum, whereby the side portions (7) may extend from the central portion (6) towards the user so as to form an arc shape as seen in a transversal direction of the article (1).

  • Patent number: 8759606
    Abstract: The present disclosure is directed to disposable absorbent articles comprising a structured fibrous web, the structured fibrous web comprising thermally stable, hydrophilic fibers that are thermally bonded together using heat producing a base substrate that is thermally stable. The base substrate is textured via mechanical treatment to increase its thickness and optionally modified via over bonding to improve its mechanical and fluid handling properties. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications.

  • Patent number: 8748692
    Abstract: Disclosed is an absorbent article having an absorbent member positioned between a liquid-permeable multilayer surface sheet and a backside sheet. A plastic film layer is laminated on the non-skin contact surface side of the multilayer surface sheet. The multilayer surface sheet has embossments in the form of a large number of elevated portions protruding outward, the elevated portions being formed by heating the sheet to a temperature higher than the melting point of the plastic film layer but lower than the melting point of the nonwoven fabric layer. The multilayer surface sheet is also provided with a large number of openings. The absorbent article has a highly spatial appearance, provides good cushioning effect with minimized skin contact, and retains uneven emboss, even upon absorption of a body fluid.

  • Patent number: 8715258
    Abstract: An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area. The absorbent article has a rear channel defining a rear closed area in the rear end region. The absorbent core is profiled within the central closed area so that the central region has a caliper that is greater than the caliper of the outside of the central closed area.

  • Patent number: 8702670
    Abstract: Controlled expansion of an intravaginal device can be achieved by selectively attaching either a primary or secondary cover to the primary absorbent device having a fluid storage element. We can determine that certain portions of the tampon will expand while other portions will be restricted to substantially the compressed structure. The primary cover can be attached to the primary absorbent device either before or after the absorbent device is compressed into final tampon form. The compression may be in the axial or radial direction or a combination of both directions. The secondary cover, if used, can be attached after the tampon pledget has been compressed into the final tampon form.
