  • Publication number: 20090090641
    Abstract: The scratch lottery coin holder is adapted for use when playing a scratch-off lottery game. The coin holder includes a housing fabricated from a pliable material having a recess for removably receiving a coin therein. An edge of the coin protrudes from the recess so that the edge may be utilized to scratch the surface of a scratch-off lottery ticket. The coin holder will have an outer surface inscribed or embossed with desired advertisement indicia or the like. The coin holder may also be combined with a key chain for convenience and practicality.

  • Patent number: 5956816
    Abstract: An elastomer coating for buttons, snaps, caps, and other metal fasteners, is provided by applying a bonding agent or primer coat to the fasteners, and then applying the elastomer material in solid sheet form to the tops or heads of the primer coated fasteners. The assembly is cured using heat and pressure, to bond the elastomer material permanently across the entire upper surface of the fasteners. The elastomer is preferably a synthetic silicone rubber material, which provides a soft to the touch feel. The permanently bonded coating also protects the underlying metal fastener material from corrosion, thus providing good durability and longevity for the fastener. The elastomer material may be clear, thus enabling any underlying pattern or design formed in the top of the fastener to be seen, but may be tinted or dyed if desired. Multiple layers of the elastomer material may be bonded to the top of the fastener, if desired, with each layer having a different translucent tint as desired.

  • Patent number: 5147098
    Abstract: A scraping device adhesively mounted on the top surface of a ski for removing ice and snow from the bottom surfaces of a ski boot. The scraping device, with a rectangular base supporting a plurality of vertical segments, symmetrically spaced, is molded from an elastomeric material having sufficient stiffness and elasticity to rotate horizontally under the compressive force of a ski boot. The top surface of each segment having a saw tooth or abrasive surface. The skier scraping the boot while asserting pressure on the scraper is able to remove ice and snow from the bottom surface of the boot.
