Aerosol insect exterminator device

Claim 1

In an insect exterminating device, an aerosol can having a liquid propellent, a rotatable valve assembly having a valve lever connected to a valve supply tube, the latter having its free end submerged in said liquid propellent, the invention comprising: a discharge orifice for said liquid propellent having an enlarged part at the forward end thereof provided with a flat edge that can be placed against a flat surface such as a wall to form an enclosure trapping an insect therein, means for venting said enlarged part, a mounting fixture inserted on the top of said can having said valve lever movably secured thereto, a connecting member connecting said enclosure to said mounting fixture, said connecting member having a flexible part, said valve lever and connecting member respectively provided with aligned abutments in the inactive condition of said device so that the valve lever cannot be depressed to discharge a quantity of liquid propellent, and when said enclosure is pressed firmly against a flat surface said flexible part is caused to flex whereby said enclosure is forced inwardly, and said abutments are caused to be moved out of alignment thereby permitting the valve lever to be depressed to release a quantity of liquid propellent through said orifice which upon sudden expansion forms a cold gas that freezes said insect within said enclosure.
