  • Patent number: 5384186
    Abstract: Cyclodextrin complex is suspended in polyalkylene glycol carrier material that does not displace the included material. The preferred perfume/cyclodextrin complexes, either alone or admixed with solvent (e.g., water), are preferably suspended in the carrier and then incorporated into solid, dryer-activated, fabric treatment (conditioning) compositions, preferably containing fabric softeners, more preferably cationic and/or nonionic fabric softeners. The perfume complexes provide fabrics with perfume benefits when they are rewetted after drying. Volatile perfume materials, including those materials that are commonly associated with "freshness" can be applied to the fabrics in an effective way.

  • Patent number: 5352711
    Abstract: Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with simple surfactants and hydrophilizing agent salts. Thus, a surfactant-containing foam is treated with a solution of, for example, calcium chloride, and is dried to leave a substantially uniformly distributed residue of hydrated or hydratable calcium chloride on the surfactant-containing internal foam surfaces. In-use, the combination of surfactant and calcium chloride hydrate provides a hydrophilic surface to the foam. Other hydratable calcium or magnesium salts such as magnesium chloride can be used. The resulting hydrophilized foams are suitable for use in absorbent devices, including diapers, sanitary napkins, bandages, and the like.

  • Patent number: 5318204
    Abstract: A resilient squeeze bottle dispensing package including an internal flexible bag which is suitable for dispensing viscous product such as toothpaste, but which includes an air valve which will automatically permit pressure equilibration in the chamber formed between the flexible bag and the interior of the bottle in response to a decrease in the atmospheric pressure surrounding the package. Employing a valve which permits such automatic pressure equilibration avoids unwanted oozing of viscous product from the discharge orifice of the package when the atmospheric pressure surrounding the package decreases, e.g., as by airplane travel or by travelling from a first elevation to a second substantially higher elevation.

  • Patent number: 5317120
    Abstract: A single use combined shipping display and cooking microwave package is provided for heating a plurality of food pieces in a microwave oven. The packaging includes a microwave transparent enclosure which has a top panel and a bottom panel. Located adjacent to and generally coextensive with the bottom panel is a microwave susceptor. Preferably this microwave susceptor is a thin film susceptor. A spacer overlays the thin film susceptor and is also generally coextensive with the bottom panel. The spacer is adapted to hold the food pieces a predetermined distance away from this susceptor. In addition, the spacer has a plurality of apertures therein which allows the heat from the microwave susceptor to pass through to the food pieces. A similar arrangement is applicable to the top panel. A top panel microwave susceptor is located adjacent to and generally coextensive with the top panel and a top panel spacer is located adjacent to the top panel susceptor and generally coextensive with the top panel.

  • Patent number: 5224655
    Abstract: Processes for selectively comminuting impure psyllium seed husk. These processes comprise milling impure psyllium seed husk in a mill which causes the husk to be fragmented by collision under conditions whereby the mean particle size of the husk material is reduced relatively more than the mean particle size of the non-husk material. In addition, processes for purifying selectively comminuted psyllium seed husk are described.

  • Patent number: 5196000
    Abstract: Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have a unique elastic waist feature that improve the dynamic fit of the elasticized waistband as well as the containment characteristics of the absorbent article. The elastic waist feature comprises an "expansive tummy panel" that is capable of expanding well- beyond the dimensions of the absorbent article set by the primary fastening system (and the original dimensions of the end edge) so as to accommodate wearers, especially large infants, with large expansile waists so as to reduce the sagging/slipping of the absorbent article. The extension forces of the elasticized waistband are lower than the extension forces of the elasticized side panels so as to accommodate such expansion. In preferred embodiments of the elastic waist feature, the elasticized waistband is formed from a stretch laminate.
