Abstract
An anti-theft, anti-intrusion and anti-overflow device having a plunger formed of a cylindrical retractable filling tube and a coaxial cylindrical plunger tube. The filling tube slides within the plunger tube between a retracted anti-overflow position and an extended filling position and has a security closure. The plunger tube has a surface with a series of openings to allow liquid to pass through during filling of a tank. The plunger tube has an anti-intrusion device to prevent the passage of foreign devices through the plunger. The plunger is designed to be mounted on a neck component of the tank.

An anti-theft, anti-intrusion, and anti-overflow device for a liquid tank comprising:
- a coaxial plunger unit (6) having a cylindrical retractable filling tube (7) and a cylindrical plunger tube (8);
- the filling tube (7) being slidable inside the tubular plunger (8) and movable between a retracted anti-overflow position and an extended filling position in which the filling tube (7) projects to an exterior and serves the tank (2) as an external filling conduit;
- the plunger tube (8) having on a lateral surface, at a desired height at a level of an upper space, a series of openings (19) for the passage of liquid during filling, the openings (19) define an upper filling space which is in fluid communication with the tank (2), a lower space (12) of the plunger tube (8) being closed on at least the lateral surface;
- the coaxial plunger unit (6) being attached to an original neck piece (3) of the tank (2) instead of a gas cap, and the new neck piece (16) defining a new tank filling orifice (4) and being compatible with an original tank filling device.
