Abstract
A generally disc-shaped token of the type having a body produced by multiple injection of plastic material and method of fabricating the same, which includes a core produced by a first injection of plastic material and having a central portion defining the central portion of the body of the token and a peripheral portion with radial projections defining at least part of the edge of the body of the token. The core incorporates an insert including a contactless electronic microchip identification device buried in the central portion during the first injection and retained at its periphery by projections or fingers attached to the injection mold and defining openings in the core. The body of the token includes a covering layer produced by a second injection of plastic material around the peripheral portion of the core to produce in conjunction with the core the whole of the edge and the annular peripheral portion of the body of the token. A decorated label is fixed to each face of the token. The token may be used as a gaming chip or a casino chip.

39. A generally disc-shaped token having a body produced by multiple injection of plastic material, the token comprising at least:
-
a generally disc-shaped core of the body of the token produced by a first injection of plastic material and having a central portion defining the central portion of the body of said token and an annular peripheral portion defining at least part of an edge of said body of the token; and
a covering layer produced by a second injection of plastic material around the peripheral portion of the core to produce in conjunction with the core one of, all or almost all of the edge and of the annular peripheral portion of the body of the token, wherein the core of the token incorporates an insert embedded in the plastic material of the central portion of said body during the first injection and comprising a contactless electronic microchip identification device. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 52, 53, 56, 57, 58, 59, 60, 61, 62, 63, 64)

51. A generally disc-shaped token having a body produced by multiple injection of plastic material, the token comprising at least:
-
a generally disc-shaped core of the body of the token produced by a first injection of plastic material and having a central portion defining the central portion of the body of said token and an annular peripheral portion defining at least part of an edge of said body of the token; and
a covering layer produced by a second injection of plastic material around the peripheral portion of the core to produce in conjunction with the core one of, all or almost all of the edge and of the annular peripheral portion of the body of the token, wherein the core of the token incorporates an insert embedded in the plastic material of the central portion of said body during the first injection and comprising a contactless electronic microchip identification device;
in the first injection, the core defines at least part of the annular peripheral portion of the body of the token;
in conjunction with the core, said covering layer defines the annular peripheral portion and the edge of the body of the token except for housings provided with injected plastic material edge inclusions produced by at least one complementary injection;
a peripheral region of the central portion of the core comprises a plurality of openings into which project portions of an insert which comprises said electronic microchip identification device;
the core comprises at least three openings evenly distributed in a circumferential direction at the periphery of the central portion of the core; and
the body of the token has on each face a cavity into which is fixed a label carrying at least one of a decoration, a mark and a hologram.

54. A generally disc-shaped token comprising:
-
a body produced by a single injection of plastic material incorporating an insert that is buried during injection in the plastic material of a central portion of said body and a contactless electronic microchip identification device;
a periphery of the central portion of said body comprising a plurality of openings into which project portions of the insert including said electronic microchip identification device; and
said portions of the insert projecting through said openings being sufficiently strong to hold the insert in place during injection of the body of the token. - View Dependent Claims (55)
