aerosol bomb
An Aerosol bomb is a hand-sized steel can charged with a liquefied gas under 75 pounds of pressure and a product to be expelled as a mist or a foam.〔Article “Aerosol Bomb”, by The Golden Home and High School Encyclopedia, Golden Press, New York, 1961.〕
Aerosol bombs were developed in 1941 by Lyle D. Goodhue and William N. Sullivan of the United States Bureau of Entomology and Plant Quarantine and a patent was granted to the pair October 5, 1943〔Patent No. 2,331,117 (Serial No. 413,474) for an aerosol “dispensing apparatus”, filed by Lyle D. Goodhue and William N. Sullivan on October 3, 1941 (including dispenser drawing), and granted October 5, 1943.〕 A public-service patent was issued on the invention and assigned to the Secretary of Agriculture for the free use of the people of the United States.〔Article "Aerosols and Insects", by W.N. Sullivan, "The Yearbook of Agriculture - Insects", United States Department of Agriculture, 1952〕
In World War II soldiers used 40 million aerosol bombs against insects. In 1946, when aerosol bombs first came on the general market, they contained only insecticides. Soon the manufacturers of shaving soap, paint, lubricants, perfume, plant sprays, hand creams, spot removers, water repellents, weedkillers, and rust preventatives were packaging their products in aerosol bombs. Even whipped cream is stored in them under refrigeration.
The directions on the can should be carefully followed, as some aerosol bombs operate only when turned upside down. These bombs do not have the delivery tube that is usually present.
