  • Patent number: 6187990
    Abstract: The invention relates to absorbent articles, such as diapers and like articles and is concerned with methods for preventing undesirable odors and/or preventing the growth of undesirable microorganisms when the articles are in use, and also provides an absorbent article which can be worn for long periods of time without generating undesirable odors, incurring the risk of infection or having a negative effect on skin. Another object is to amplify the presence in the wearer's urogenital zone of microbiological flora that will assist in preventing the occurrence of urinal tract infections. These objects have been achieved by adding to the absorbent articles microorganisms which exhibit antagonistic properties against present undesirable strains of microorganisms, so as to restrain the growth of these or establishing of new undesirable species.

  • Patent number: 6129720
    Abstract: An absorbent article includes an absorbent pad and an outer cover. An extensible layer replaces at least one of the tissue layers of the absorbent pad. The extensible layer can be secured to an extensible bodyside liner or an extensible outer cover. The extensible layer is adhesively secured to the inner surface of the outer cover or the bodyside liner. In embodiments where the outer cover is extensible in a cross-direction and/or a longitudinal direction, the extensible layer is extensible in the same directions and moves with the outer cover. Absorbent core is not physically secured to the extensible layer. Thus the extensible layer has free mobility with respect to the absorbent core when the outer cover is extended, without deleterious effect on the absorbent core, or the absorbent pad as a whole. Therefore, tearing of the absorbent pad and damage to, or release, of superabsorbent material from the absorbent pad is prevented.

  • Patent number: 6107538
    Abstract: Described are absorbent members useful in the containment of body liquids such as urine. The storage members have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at relatively high capillary pressures, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section of the disclosure. The absorbent members may include an osmotic absorbent (preferably a hydrogel-forming absorbent polymer) or a high surface area material, or a combination thereof.

  • Patent number: 6068620
    Abstract: A disposable absorbent garment comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and backsheet is disclosed. The absorbent core is formed from at least one and preferably more than one laminate comprising three layers, including an upper layer, a lower layer and a central fibrous layer containing from about 50-95% by weight superabsorbent polymer. The upper and lower layers comprise tissue, airlaid fluff pulp or synthetic non-woven fibrous layers. The upper and lower layers together assist to maintain the integrity of the core during manufacture and in use, contain the superabsorbent polymer within the insult area of the garment and act to diffuse multiple insults so that gel blocking is minimized. The absorbent garment thus formed is very thin, lightweight and economical.

  • Patent number: 6063981
    Abstract: Disclosed is the use of an adhesive to prepare a disposable absorbent product intended for the absorption of liquids such as body liquids. It is generally desired that the adhesive exhibits a storage modulus greater than about 1.times.10.sup.8 dynes per square centimeter across the temperature range of about 0.degree. F. to about 130.degree. F. The use of such an adhesive results in a reduced visibility of the adhesive through the outer sheets, such as breathable films, of a disposable absorbent product to a wearer or user, thereby improving the aesthetics of the disposable absorbent product.

  • Patent number: 6060636
    Abstract: Disclosed is an improved structure that includes a nonwoven web including a viscoelastant treatment. The treated web, when contacted by a viscoelastic fluid such as menses alters the viscoelastic properties of the fluid and enhances its wicking and distribution throughout the absorbent structure. A desirable viscoelastant is a alkyl polyglycoside, particularly those having 8 to 10 carbon atoms in the alkyl chain. When applied so as to provide an amount of about 0.1% to about 5.0% solids add-on based on the weight of the dry nonwoven web, rapid fluid wicking and distribution may be obtained. Other viscoelastants are disclosed. Advantageously the treatment may be applied as a high solids composition using conventional application means such as spray coaters and the like or as an internal additive. The absorbent structure finds particular utility as a distribution layer component of a sanitary napkin for absorbing menses as well as other blood handling products such as surgical drapes, for example.
