Patents by Inventor Luther E. Stockton

Luther E. Stockton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8741427
    Abstract: A microcavity-containing, resilient foam comprising a thermoplastic polymer; composite structures comprising such a microcavity-containing foam and a multiplicity of particles contained in such microcavities, preferably aqueous fluid absorbent particles; methods for preparation of such foam and structures; and disposable consumer articles incorporating such foams and composites. The aqueous fluid absorbent characteristics of the foam and composite structures render them useful in the fabrication of disposable consumer articles, in particular hygiene articles designed to rapidly absorb “insults” of bodily fluid thereby conducting such fluids away from contact with the skin of the wearer of the hygiene article. The useful articles include infant and children diapers, adult incontinence pants, feminine hygiene pads, pet urine-absorbent pads and mats, household cleaning pads, surgical drapery, and the like.

  • Patent number: 8686056
    Abstract: Olefin polymer-based, durable, open-cell foam compositions, structures and articles derived from same; methods for preparation of such foams; and use of the dry durable foams in various applications are disclosed. Further described is use of the foams and structures and articles made of same in absorption, filtration, insulation, cushioning and backing applications, and in particular for odor removal, hygiene and medical applications due to, among other properties, good absorption capabilities, softness and/or flexibility of the foams and their recyclable nature.
