ABSTRACT:
A container for pressurized gas, having a valve for filling and emptying the container, a frangible safety relief cup located near the valve and a deflector plate attached to the bottom portion of the valve. The safety relief cup is frangible so that the safety relief cup will rupture if the container is filled to too high of a gas pressure. The problem with such safety feature is that upon rupture the escaping gas often travels in an upwards direction at a very high speed, allowing the discharging contents to spray on the face or upper torso by the person causing injury to the face of refrigerant frost bite or the like. The deflector plate is wide enough and extends far enough over top of the frangible safety relief cup to prevent the upwards flow of the escaping pressurized gas from the ruptured safety relief device. Also, if the safety relief cup itself breaks lose due to gas pressure in the container, the deflector plate protects the person standing above the container from being hit in the face or upper torso by the flying safety relief device.
