Shoe Filling Patents (Class 106/38)
  • Patent number: 10772377
    Abstract: In aspects of the invention, a footwear sole can include a sole member formed of a single unitary layer, wherein the sole member is formed of a compound including ethyl vinyl acetate (EVA) and rubber. The compound can further include a bulking agent. The compound can further include a foaming agent, a color master agent and a bridging agent. The sole member can include a top surface, the top surface including a plurality of apertures defined in a rear portion of the top surface. The plurality of apertures can define a tapered shape, and a first aperture of the plurality of apertures can have a depth that is less than a second aperture of the plurality of apertures. The plurality of apertures can be arranged in a plurality of rows.

  • Patent number: 9986785
    Abstract: A method of insert molding comprises placing in a first mold a curable rubber composition comprising a reactive species; placing on a surface of the rubber composition a first thermoplastic material in a film or layer comprising a group reactive with the reactive species of the rubber composition; curing the rubber composition in the mold to form a first molded article of cured rubber having a first thermoplastic material layer covalently bonded through reactive of the reactive species and the group; placing the first molded article as an insert into a second mold, the cured rubber contacting an inside surface of the second mold and the thermoplastic layer facing into the second mold cavity; closing the second mold and injecting into the second mold a second thermoplastic material that to form a second molded article comprising the first molded article thermally welded and/or covalently bonded to the second thermoplastic material.

  • Publication number: 20040000255
    Abstract: The present invention discloses a compound and a method for a cushion pad that is bonded to an outsole without the need for glue or other adhesives. This cushion pad can be softer and more flexible then the outsole but can be similar enough in composition to be recyclable without having to separate it from the outsole. The compound can consist of a styrene-butadiene-styrene triblock copolymer, ethyl-vinyl-acetate, peroxide, a filler agent, and a blowing agent. The combination of these materials will form a high rubber content foam sheet that is very soft and shock adsorbing. This process can use the above compound to manufacture a rubber outsole with an integrated cushioning pad that can be manufactured in one step.
