Abstract
A pressurized container contains a product to be dispensed and a propellant gas. The container includes a closed reservoir, a cylindrical neck, a dispensing head mounted on the neck and a safety device. The safety device can prevent an accidental excess pressure inside the container and includes an annular resilient retaining mechanism that surrounds the neck. The annular resilient retaining mechanism is capable of tightly gripping the dispensing head on the neck in a leakproof manner when an internal pressure of the reservoir is below a predetermined value. The annular resilient retaining mechanism is further capable of moving the dispensing head away from the neck so as to create a communication between an inside of the container and atmosphere when the internal pressure exceeds the predetermined value.
