• the antitheft device according to the invention is described in the following according to a particular example of implementation for the protection of metal cans.
• It consists of a movable molded shell (100) and a fixed molded shell (200).
• the two hulls are together by a pivot (250) engaged in protuberances (131, 241) provided at the peripheral edge of the shells (100, 200).
• the fixed shell (200) has a generally cylindrical shape, whose cross section corresponds to the cross section of the article (1) to be protected.
• the fixed shell (200) has two transverse walls (203, 204) which are solid in the example described. They can also have lights to lighten the anti-theft device.
• the upper transverse wall (204) is, however, preferably solid to completely seal the device and prevent access to the can lid and the opening ring.
• transverse walls (203, 204) define between them a cavity (205) with a height of 5 to 10 millimeters, closed on the opposite side to the mobile shell (100) by a peripheral edge and open on the side of the movable shell (100) by a slot allowing the penetration of the mobile shell.
• the fixed shell (200) has a skirt (201) extending over half of the periphery of the article (1) to be protected, on the opposite side to the mobile shell (100).
• This peripheral skirt (201) has on its inner surface a peripheral shoulder (202) which engages under the shoulder (2) surrounding the upper edge of the article (1).
• This shoulder (2) may be constituted by a peripheral groove or by the upper surface of a peripheral groove.
• the detection means is remote from the surface of the article to be protected by a distance of more than 5 millimeters and preferably more than 10 millimeters. This distance limits the disturbances caused by the metallic mass on the operation of the radio frequency detection. This distance results from the height of the cavity (205) and the plates (203, 204) and possibly a base provided in the protrusion (210).

• This skirt (201) also has a shoulder (202) engaging in the peripheral rib (2) of the article to be protected (1).
• the connection between the shells (100, 200) is provided by a pivot (250).
• a spring (132) surrounding this pivot (250) causes the opening of the movable shell (100) relative to the fixed shell (200) when they are unlocked.
