A pressure control fill valve (1) for a pressurized dispenser container comprises a first and second end (2, 3) and a base (4), a first and second circumferential lip (5, 8). The lips (5, 8) enable placement of the valve in an opening of a pressurized dispenser container in first a position, where a propellant gas can be filled into the container and a second position for complete closing of the container. According to the invention, the second lip (8) of the valve (1) is asymmetric about its circumference. This prevents the valve (1) from being pushed out of the opening of the container in case of high over-pressure or enlargement of the opening due to a temperature increase. The invention eliminates the hazard of a loss of valve and propellant gas in case of high temperature. |
