A method of producing a gaming chip comprising at least two plaques forming the opposite faces thereof, the method comprising a step of connecting said two plaques placed against one another by arranging therebetween a connection material. The method comprises (i) a step of arranging in a mold two blanks of said two plaques which are placed against one another with the faces thereof facing one another, the total thickness thereof being smaller than that of the finished chip, the mold having an impression with a shape complementary to that of the chip to be produced, (ii) a step of holding the periphery of the plaque blanks within the mold, and (iii) a step of injecting connection material under pressure between facing faces of the two plaque blanks at a pressure and temperature suitable for deforming the plaque blanks against the surface of the impression of the mold.

Method of producing a gaming chip, and a gaming chip comprising two plaques

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.

Electronic microchip token and its fabrication process

The chip, in the general shape of a disk, of the type with a body obtained by multiple injection molding of plastics material, includes a coreobtained by a first plastics material injection molding operation having a central portiondefining the central portion of the body of said chip and a peripheral portiondefining, by means of radial projections, at least a portion of the edge of the body of the chip. The coreincorporates an insertincluding a contactless electronic microchip identification devicethat during the first injection molding operation is buried in the central portionand retained at its periphery by projections or fingers attached to the injection-molding mold and defining aperturesin the core. The chip body includes a covering layer around the peripheral portionof the coreobtained by a second plastics material injection molding operation to produce, with the core, the whole of the edge and the peripheral annular portion of the body of the chip. A decorated label is fixed to each face of the chip. The chip may be used as a gaming chip or a casino chip.

Chip with insert including an electronic microchip

Token including a token body obtained by at least one injection of material around an insert including a contactless identification device attached to a rigid plate sandwiched between two layers of injected material, the rigid plate including at least one through-hole. The invention also concerns the method of manufacturing such a token, including placing the insert in a mold, injecting a plastic material around the insert to form at least a portion of the core of the token, and at least one injection of plastic material around the assembly formed by the insert and the portion of the core obtained after the first injection of plastic material.
