Abstract
A composite gaming chip which includes a strong frame made of a brass ring with axial protrusions and a central aperature with notches. A display or electronic transponder is situated between two clear polycarbonate disks each having a recessed face surrounded by a rim. Tabs radially extending from each disk engage the notches in the brass ring. The assembly is inserted into the cavity of a plastic injection mold where it is bonded together by an injected thermoplastic. The gaming chip can be ground flat without scratching the clear recessed face of either disk.
Claims19
A gaming chip comprising:
- a metal ring defining a central aperture, said metal ring having a plurality of axial protrusions and a plurality of radial protrusions, each having inner and outer surfaces;
- said radial protrusions defining an outer periphery of said metal ring, said metal ring defining a plurality of radial notches open to said central aperature;
- two cover disks each having a back face and a clear face, said two cover disks being situated in back-to-relationship with said central aperature;
- a plurality of tabs extending radially from each of said two cover disks for association with said plurality of radial notches so to align said two cover disks with said metal ring;
- a rim extending axially outward from said clear front face of said cover disks to define a central axial recess on said clear face of each of said two cover disks;
- and
- a thermoplastic material substantially encapsulating said metal ring and said two cover disks except for said clear front face, said outer surfaces of said axial protrusions and said outer surfaces of said plurality of radial protrusions which face away from said gaming chip.

A gaming chip comprising:
- a metal ring having a central aperature and a plurality of axial protrusions and a plurality of radial protrusions, said radial protrusions defining an outer periphery of said metal ring, said metal ring further having a plurality of radial notches open to said central aperture;
- an insert disposed within said central aperture;
- two cover disks each having a back face and a clear front face, said two cover disks being situated in back-to-back relationship within said central aperture with said insert sandwiched therebetween;
- a plurality of tabs extending radially outward from each of said two cover disks for association with said plurality of radial notches to rotationally align said cover disks with said metal ring;
- a rim extending axially outward from said clear front face of each of said two cover disks to define a central axial recess on said clear front face of each of said two cover disks;
- and
- a thermoplastic material substantially encasing said metal ring and said two cover disks except for said outer surfaces of said axial protrusions and said plurality of radial protrusions which face away from said gaming chip.

A gaming chip comprising:
- a metallic ring consisting of a material selected from the group consisting of copper alloy and other metal alloy and defining a central aperture, said metal ring having a plurality of axial protrusions and a plurality of radial protrusions, said radial protrusions defining an outer periphery of said metal ring, said metal ring defining a plurality of radial notches open to said central aperture;
- an insert disposed within said central aperture, and having at least a design and a message;
- two cover disks consisting of transparent polycarbonate and each having front and back faces, said two cover disks being situated in back-to-back relationship within said central aperture with said insert sandwiched therebetween and visible through said faces;
- a plurality of tabs extending radially outward from each of said two cover disks and into said plurality of radial notches so as to align said two cover disks with said metal ring;
- a rim extending axially outward from said clear face of each of said two cover disks to define a central axial recess on said dear face of each of said two cover disks, said rim extending axially outward beyond said plurality of tabs;
- and
- an encapsulation consisting of an opaque thermoplastic material having a generally lower melting temperature than said two cover disks consisting of polycarbonate, said thermoplastic encapsulation substantially encasing said metal ring and said two cover disks except for said central axial recess and said outer surfaces of said axial protrusions which face away from said gaming chip.
