  • Patent number: 8912384
    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.

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.

    Abstract: A tampon having at least one physical discontinuity is provided. The physical discontinuity, or physical discontinuities, are located in the compressed absorbent member and may be made in the tampon pledget before the pledget is compressed into the absorbent member.

  • Patent number: 8556874
    Abstract: The absorbent article provides a signal viewable from the top surface of the absorbent article which gives a perception of depth within the absorbent article. This creation of depth perception is accomplished by the use of at least two tones within a color and/or by the use of multiple tones and multiple colors operating together to create a perception of depth within the absorbent article.

  • Patent number: 8524355
    Abstract: A disposable absorbent article includes an absorbent mat provided between a liquid-permeable top sheet and a liquid-impermeable back sheet. Herein, the absorbent mat includes a sheet-like water-absorbent layer that contains a water-absorbent resin powder but that does not contain pulp fibers, and a fiber assembly layer that contains both the water-absorbent resin powder and the pulp fibers, the sheet-like water-absorbent layer and the fiber assembly layer arranged sequentially in this order from a top sheet side. The fiber assembly layer includes a fiber presence region in which both the pulp fibers and the water-absorbent resin powder are present, and a fiber absence region in which both the pulp fibers and the water-absorbent resin powder are absent, the fiber presence region and the fiber absence region formed to be adjacent with each other.

  • Publication number: 20130178811
    Abstract: An absorbent article has a liquid-permeable top sheet of a white non-woven fabric, a liquid-impermeable back sheet opposing the top sheet, and an absorbent between the top sheet and the back sheet. A colored element is provided on the side of the top sheet that does not contact the skin, is visible through the top sheet, and is colored to a color other than white. The top sheet has protrusions and indentations in the thickness direction. The basic weight of the protrusions is greater than the basic weight of the indentations. The color difference between the Lab value of the color of the colored element visible through the protrusions of the top sheet and the Lab value of the color of the colored element visible through the indentations of the top sheet is 2.8 or more.

  • Publication number: 20130165884
    Abstract: A liner for incontinence includes a skin contact side sheet, a non-skin contact side sheet, and an absorbent body arranged between these sheets and including an absorbent material. The absorbent material includes 30 to 70 mass % of SAP. The liner includes a main body and wings in an intermediate region of the main body. An SAP basis weight in the intermediate region is larger than in front and rear regions of the main body. The main body includes a front compressed region which is positioned between the intermediate region and the front region immediately in front of a urinating position (UP) of a wearer when worn, side compressed regions which extend from the intermediate region to the front region and rear region, respectively, and a rear compressed region which extends in the rear region in substantially the width direction. At the compressed regions, the absorbent body is continuous.

  • Patent number: 8450557
    Abstract: The top sheet for an absorbent article has a plurality of fused compressed sections, wherein the fused compressed sections are located on the lowermost side in the thickness direction of the top sheet, and the back side of the top sheet has recesses or low density regions having the lowest density within the top sheet, surrounding the fused compressed sections. The top sheet for an absorbent article having a plurality of fused compressed sections can be produced by a process wherein a top sheet is situated between a member with multiple protrusions and a member with multiple recesses that engage with the multiple protrusions, and the protrusions are pressed into the recesses.

    Abstract: An absorbent article that includes a first absorber. The first absorber is disposed over an excretion opening contact region in the absorbent article and a posterior region. In a width direction of the absorbent article, the first absorber is configured to be longer than a second absorber. The second absorber is not disposed in the excretion opening contact region but disposed in the posterior region. A liquid-penneable sheet is disposed farther inwardly of the skin contact surface side of the absorbent article than the second absorber over the excretion opening contact region and the posterior region. In the width direction, the liquid-penneable sheet is configured to be shorter than the first absorber.
