ABSTRACT:
A portable disposable fire extinguisher comprises a container for fire extinguishing medium, a discharge head, and a valve device within the discharge head for controlling a discharge passage. The valve is normally biased to a closed position by a return spring and by pressure in the container. The discharge head is constituted by a one-piece moulding providing a valve body, a carrying handle, a discharge nozzle and an operating lever which is connected to the valve body by a plastic hinge. Accidental operation of the lever is prevented by a discardable stop plate forming part of the moulding and connected thereto by frangible connections.
