Gaming chip

The present invention relates to a gaming chip comprising a transparent top wall, a bottom wall and a circumferential wall extending there between, said walls forming a cavity, in accordance with the preamble of claim 1.

Casino chips of differing shapes, sizes and colours are well known and differs depending of the value and the gaming establishment and casino where the chips are being used. Nowadays it is also known to use casino chips having a central transparent portion, which makes an inner unit visible to the observer, on one or on both sides of the chip.

In U.S. Pat. No. 6,352,261 it is known a gaming chip with a generally toroidally shaped body, a hollow sealed chamber fixedly mounted generally centrally within said toroidally-shaped body; and at least one discrete particle loosely mounted and movable within said hollow sealed chamber so that, when said chip is shaken, said particle abuts against the walls of said hollow sealed chamber providing a rattling sound. In U.S. Pat. No. 6,021,949 and in U.S. Pat. No. 5,676,376 there are also known gaming chips with a hollowed body in which a unit is placed. These units can\'t be replaced without damaging the gaming chip.

All gaming establishment and casinos add their trade mark or/and logotype to their gaming chips. This invention enables all gaming establishment, casinos and private players to add their special unit, that, for example, can be a material, message, logotype or denotation in an interchangeable way.

When putting such a unit in a casino chip an overpressure is created in said cavity as a consequence. The result of the overpressure might be that the at least one wall of transparent material releases from the outer frame resulting in an exposure of the content in the cavity.

The object of the present invention is to provide a gaming chip that can be easily releasable and attachable and that overcome the problems mentioned above.

To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

These objects are achieved by the present invention as defined in the independent claim 1. Appropriate embodiments of the invention are set forth in the dependent claims.

Thus, there is defined in accordance with the present invention a gaming chip comprising a transparent top wall, a bottom wall and a circumferential wall extending there between, said walls forming a cavity, characterized in that at least one of the top and bottom walls being arranged to be easily releasable and attachable, the circumferential wall comprises an aperture and in that the gaming chip further comprises valve means arranged to open or close said aperture.

The advantage afforded by the inventive gaming chip resides in that the circumferential wall of the gaming chip is provided with an aperture and that the gaming chip comprises a valve means arranged to open and close said aperture. As a result of this arrangement it is possible to discharge an overpressure inside the gaming chip. For instance, the valve means can be a screw or a plug.

According to another preferred embodiment of the inventive gaming chip, said gaming chip further comprising a seal arranged to seal between the releasable/attachable wall and the circumferential wall.

According to another preferred embodiment of the inventive gaming chip, said gaming chip further comprises a unit in said cavity. This enables a user to provide the cavity of the gaming chip with any type of material, message, logotype or denotation etc, that he/she prefers. For example, said unit can be fixed mounted in said cavity.

According to another preferred embodiment of the inventive gaming chip, said valve means is formed to be arranged detachably in said aperture. This enables the chip to be dismounted and hence the user can change or add other type of material, message, logotype or denotation etc, that he/she prefers.

According to another preferred embodiment of the inventive gaming chip, said circumferential wall is circular.

According to another preferred embodiment of the inventive gaming chip, said sealing device is a gasket.

According to another preferred embodiment of the inventive gaming chip, said circumferential wall is circular.

These preferred embodiments of the inventive duct connecting device are set forth in the claims dependent on the accompanying claim 1.
