ABSTRACT:
A safety valve locking device is disclosed and includes a collar adapted to fit over a valve rim. A slide member is provided for selectively preventing and permitting the depression of an actuator head arranged on a valve stem to actuate a valve assembly of a pressurized container. The slide member includes a leading end and a trailing end and an aperture arranged therebetween through which the valve stem extends. The slide member is movable when pressure is applied or released from the trailing end thereof, between an occluding position at which the actuator head on a valve stem is misaligned with the aperture so that the valve stem cannot be depressed downwardly therethrough and a nonoccluding position at which the actuator head is aligned with the aperture so that the valve assembly can be actuated upon depression of the valve stem. A plurality of resilient members for urging the slide member to the occluding position are arranged within the inner perimeter of the collar and are connected between the first surface of the collar and the slide member.
