Abstract
A non-refillable cylinder that includes a hollow container body designed to hold pressurized gas, with a port for gas release. A one-way valve is securely coupled to the port through a threaded clamping portion. The valve is designed with a specially shaped end that prevents its removal from the container body. The valve is movable between a pressurization position, where it prevents gas leakage, and a safety position, where the valve remains securely in place. Venting features are provided to allow the safe escape of gas from the container when the valve is in the safety position, mitigating risks during damage or tampering.

A non-refillable cylinder, comprising:
- at least one hollow container body adapted to contain pressurized gas and provided with at least one end portion on which at least one port for the gas outlet is obtained;
- at least one one-way valve associated with said container body, adapted to allow the gas to escape from said container body and provided with at least one threaded clamping portion coupleable to said port in a threaded manner;
- retaining means associated with said container body and adapted to prevent said valve from being removed from said container body;
- wherein:
- said retaining means comprise at least one retaining body arranged internally to said container body where said port is located and comprising at least one flexible portion defining a passage hole aligned with said port along an axis and adapted to house a stretch of said valve within it;
- said valve comprises at least one retaining end of substantially widened conformation, adapted to allow said valve to be fitted into said container body and adapted to prevent said valve from being pulled out of said container body, said valve being movable along said axis between a pressurization position, wherein said clamping portion is coupled to said port and said retaining end is spaced apart from said flexible portion, and a safety position, wherein said clamping portion is uncoupled from said port and said retaining end is arranged to stop against said flexible portion;
- and wherein
- said cylinder comprises venting means adapted to allow the escape of the gases contained in said container body when said valve is in said safety position.
