  • Patent number: 6514504
    Abstract: The present invention relates to substantially uniform, discontinuous films of a skin care product having a defined average particle size, particle spacing and coverage value. The films provide improved skin appearance, e.g., good apparent coverage and a natural look. The films can be formed by any method which provides the defined particle size, particle spacing and coverage value, including silk screening and the like and electrostatic spray techniques. The films are preferably formed by electrostatically spraying the composition onto the skin.

  • Patent number: 6514602
    Abstract: A film which is water-flushable and biodegradable that is particularly useful as a backsheet for disposable absorbent articles, and in particular flushable interlabial catamenial products. The film comprises: (1) a relatively thin water-impervious biodegradable layer to maintain the integrity of the film during use and to minimize or prevent aqueous liquids from penetrating through the film; (2) a relatively thick substantially water-soluble layer adjacent the water-impervious layer to cause the film to lose integrity after the film is flushed; and (3) a relatively thin substantially water-permeable layer adjacent the water-soluble layer to control the rate at which water and other aqueous liquids contact, dissolve and disintegrate the water-soluble layer.

  • Patent number: 6513975
    Abstract: A bag made of flexible sheet material having an opening defined by a periphery. Juxtaposed with the periphery is a closure zone. The closure zone has induced extensibility in a direction perpendicular to the opening of the bag so that handle ties may be conveniently formed upon extension of the closure zone material. The handle ties are bound together to form an integral closure for the bag. The induced extensibility is provided by a network of dual regions having different modes of extensibility. The dual region network also provides the advantage of an increased gripping surface for forming the handle ties.

  • Patent number: 6514929
    Abstract: The present invention relates to a process for forming an agglomerated particle containing the steps of providing at least one alkaline material, a core material, and at least one acid active. The alkaline material and the core material are added to a mixer and agglomerated therein, to form an agglomerated particle comprising an interior and an exterior. The acid active is then added to the mixer. The core material is concentrated into the interior of the agglomerated particle by adding substantially all of the core material to the alkaline material before more than about 50% of the acid active is added to the mixer.

  • Patent number: 6514445
    Abstract: A process for forming a grooming implement is provided. The steps include providing a blank having a head and a handle, wherein the head has one or more void spaces which divide said head into at least two segments, and injecting an elastomer into the void space at a temperature of at least about 245° C. thereby fusing the elastomer to the segments and forming a resiliently flexible joint. The elastomer is the sole mechanical link between the segments such that the segments can flex relative to each other and the elastomer can be stretched to about 120% of its unstressed length without separation of the elastomer from the segments.
