Patents by Inventor Richard Bambara

Richard Bambara 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: 20010000568
    Abstract: The invention relates to foam structures with enhanced physical properties which can be used in the areas of packaging, athletics, water sports, and construction. In general, the structures are laminated polymer foams that include a core of a low density foam and one or more skins of relatively high density foam covering the core. The skins provide improved physical properties to the foam structures by improving the flexural strength, resistance to bending, and resulting damage from bending in the laminated foam structure while modestly increasing the weight of the laminated structure, for example. Uses of the foam structures include, but are not limited to, packaging materials, gym mats, body boards, or eaves fillers. The skin can act as a hinge to fold a die cut piece into a collapsible packaging system.

  • Patent number: 6054005
    Abstract: Polymer structures having a laminated surface and enhanced physical properties that can be used for packaging, athletic gear (e.g., padding, water sport equipment), gaskets, and protective garments are described. The structures include a core of a relatively high density material and one or more layers laminated to the surfaces of the core material of relatively low density polymer foam. The structures can be stiff or flexible. The foam layers improve the softness of the surfaces of the core material.

  • Patent number: 5998006
    Abstract: An extruded article having elongated variegations is described. The variegated extruded article has a plurality of elongated variegations that are substantially parallel to the direction of extrusion of the article. The number of elongated variegations in the article and the widths of the variegations can be adjusted by modifying processing conditions.

  • Patent number: 5844009
    Abstract: The invention relates to physically-blown low density polyethylene (LDPE) foams that are blends of an LDPE resin and a silane-grafted single-site initiated polyolefin resin. The LDPE resin generally has a density between about 0.91 and about 0.93 g/cm.sup.3 and a melt index greater than 1, and the silane-grafted single-site initiated polyolefin resin generally is a copolymer of ethylene and a C.sub.3 -C.sub.20 alpha-olefin that has a density between about 0.86 and about 0.96 g/cm.sup.3 and a molecular weight distribution between about 1.5 and about 3.5.
