Electronic microchip token and its fabrication process
First Claim
1. A generally disc-shaped token having a body produced by multiple injections of plastic material, the token comprising:
- a generally disc-shaped single-piece 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, wherein said insert is secured between a first half-shell and a second half-shell of a first injection mold during said first injection of plastic material such that said resulting generally disc-shaped single-piece core is a single-piece construction with said insert being embedded within said plastic material of the central portion of said body of said core upon completion of said first injection.

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.

20. A generally disc-shaped token having a body produced by multiple injection of plastic material, the token comprising at least:
-
a generally disc-shaped single-piece 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 and wherein said insert is secured between a first half-shell and a second half-shell of a first injection mold during said first injection of plastic material such that said resulting generally disc-shaped single-piece core is a single-piece construction with said insert being embedded within said plastic material of the central portion of said body of said core upon completion of said first injection; 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.

21. A method of fabricating a body of a token comprising:
-
placing an insert comprising a contactless electronic microchip identification device in a first injection mold, two half-shells whereof define a first imprint corresponding to a generally disc-shaped core of the body of the token; holding said insert at a center of the first imprint by axially clamping the insert between the two half-shells of the first mold; injecting the core of the token; placing the core of the token in a second injection mold, two half-shells thereof defining a second imprint corresponding to one of all or almost all of the body of the token; holding said core at a center of the second imprint by axially clamping a central portion of the core between the two half-shells of the second mold; and injecting a covering layer. - View Dependent Claims (22, 23, 24)
