  • Patent number: 8247637
    Abstract: A mini pad is provided with a chilled skim milk additive which is useful for reducing vulvar inflammation and lowering the acidity of a female's vulva which result from vaginal secretions which leak onto the tissue of the vulva. The mini pad can be provided with a self-contained cooling component which can be frozen or, when compressed and ruptured, will lower the temperature of the mini pad to provide the soothing cold. The skim milk can be incorporated into the mini pad in several different ways. The mini pad is useful for soothing and healing vulvar irritation, and it is mobile and can be easily used during normal daily activities without any problems whatsoever.

  • Patent number: 8227658
    Abstract: A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain. The “kinks” in the second copolyester backbone reduce its melting point and degree of crystallinity, which have an influence on its physical properties (e.g.

This spatial distance is at least in part a function of a movement speed at which the article is to be moved relative to the skin while in contact therewith. In one method of making such a substrate, the movement speed and a temporal frequency are selected and used to determine the spacing between surface features on the skin-contact surface of the substrate.

  • Publication number: 20120089067
    Abstract: A laminate having health-benefit agents therein is made by particle stabilization within the lamination process. By changing the substrate type (tissue, nonwoven, film) and/or the physical composition and/or attributes of the laminate layers, the release of the health-benefit agents can be controlled. The laminate, sometimes referred to as a liner, may be used in personal absorbent articles such as diapers, feminine pads, bandages, bed pads, and the like.

  • Publication number: 20120089106
    Abstract: An absorbent article includes a topsheet having a contact surface in contact with the skin of a wearer; a liquid-impermeable backsheet through which a liquid does not pass; and an absorber provided between the topsheet and the backsheet, a cooling sensation material including a refresher agent in the topsheet or between the topsheet and the backsheet. On the outside of the planar direction of the topsheet from the contact region in which an excretion unit of the wearer is in contact in the topsheet, there is a region having a greater amount of the cooling sensation material per unit area than the amount of the cooling sensation material per unit area in the contact region.

  • Patent number: 8153857
    Abstract: The present invention relates to absorbent articles and composites that provide improved protection and comfort by use of a vapor permeable, liquid barrier layer and an exudates thickener. In particular, the barrier layer results from deposition of barrier coating on one or more regions of the barrier layer such that select regions of the overall article exhibit a barrier to liquid while the article in general is still deemed breathable.

  • Patent number: 8148598
    Abstract: A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

  • Publication number: 20120071847
    Abstract: A sanitary napkin is disclosed as a form of disposable absorbent article. It has an absorbent core and a hydrophobic topsheet that has an upper side that is to be worn against a user's body. The topsheet is selected from a group of nonwoven topsheets and apertured film topsheets. A trace amount of a fibrous superabsorbent material, in the range of 0.30 and 3.5 grams of superabsorbent material per square meter, is provided in a fibrous matrix in a secondary topsheet that is in intimate contact with the lower side of the topsheet. The fibrous matrix is made by airlaying the superabsorbent material with cellulose and bi-component fiber onto a non-woven carrier.

  • Patent number: 8137327
    Abstract: A vaginal drug delivery system includes a device formed of porous material that holds a flowable therapeutic formulation. The device, preferably in a soft, prewetted state, is inserted into the vagina to reside typically at or near the cervix where it continuously releases the flowable therapeutic formulation through its outer surface which is in contact with the vaginal surfaces. In operation, the flowable therapeutic formulation migrates via capillary forces from a reservoir that is centrally located in the device and through a covering that envelopes the reservoir.
