ABSTRACT:
The invention relates to a safety cap for a device for dispensing a liquefied gas propellent including one or more active ingredients such as is used for insecticides or exterminating purposes. More particularly, the device, which is commonly known as an "Aerosol Bomb" comprises a container of conventional type having a discharge nozzle which when pressed will activate a valve to release the contents of the container as a spray. The container has an annular flange at its upper end and the cap, according to the invention, has a cylindrical side wall with means at its lower edge to interengage with the annular flange to retain the cap in position yet permit relative longitudinal movement of the cap with respect to the nozzle. The cap has inwardly movable means carried by the side wall thereof releasably to grip the nozzle so that when the cap is moved longitudinally outwardly with respect to the container; the gripping means are then moved inwardly to engage the nozzle and the cap is then moved longitudinally inwardly with respect to the container with the nozzle still gripped, the valve controlled by the nozzle will be actuated for discharge of the contents of the container.
