Patents by Inventor Fred Radwanski

Fred Radwanski 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).

  • Publication number: 20070148433
    Abstract: An absorbent elastic laminate includes an elastic backing layer and a flexible thermoplastic absorbent foam layer. The flexible absorbent foam layer gathers when the laminate is in the relaxed state, permitting the elastic backing and the overall laminate to exhibit elastic stretch and recovery properties. The absorbent elastic laminate is useful in a wide variety of personal care absorbent articles, medical absorbent articles and absorbent wiping articles.

  • Publication number: 20070148432
    Abstract: A hybrid absorbent foam includes an integrated hybrid foam layer having an open surface, a closed surface, and a foam body extending between the open and closed surfaces. The integrated hybrid foam layer has an open-cell content of at least 50%, while the closed surface provides a barrier to aqueous liquids. The integrated hybrid foam layer is formed as a single layer, and has a substantially uniform polymer composition throughout its thickness. The integrated hybrid foam layer combines the functions of liquid absorbency, retention, and barrier into a single layer, and is useful in a wide variety of absorbent articles.

  • Publication number: 20060148917
    Abstract: A flexible, absorbent, thermoplastic foam comprises at least a thermoplastic base resin and fibers. The incorporation of fibers into the thermoplastic base foam structure can result in a foam which exhibits improved absorbent properties such as high fluid capillary action and improved fluid movement from cell to cell within the foam, while maintaining sufficient integrity and flexibility for specific applications. In some aspects, the use of fiber having high surface energy can increase the overall surface energy of the foam, which in turn can further enhance absorbent properties.

  • Publication number: 20060030632
    Abstract: A soft, flexible, low-density, open-cell, thermoplastic, absorbent foam formed from a foam polymer formula including a balanced amount of a plasticizing agent and a surfactant in combination with a base resin. Thermoplastic elastomers can be added to the foam polymer formula to improve softness, flexibility, elasticity, and resiliency of the resulting foam. The surfactant may be either a single surfactant or a multi-surfactant system. The foam possesses a number of qualities, such as softness and strength, which render the foam particularly suitable for use in a variety of personal care products, medical products, and the like.

  • Publication number: 20050228350
    Abstract: An absorbent structure expands to a greater extent along one surface than along an opposite surface when in the presence of a liquid. The absorbent structure may include a single layer, or two or more layers intimately bonded to one another. When in the presence of a liquid, the more expandable surface causes an increase in concavity in the X-Y plane of the structure, with the concavity being in the direction of the less expandable surface. One or both surfaces can be treated to adjust the respective level of expandability. By inducing a formed shape upon hydration swelling, a trough shape can be generated to facilitate absorbent properties, containment, and fit. The invention includes absorbent articles having such an absorbent structure incorporated therein.
