The Cook Laboratories, Inc., a Chicago firm that made bacterial vaccines, introduced the term “Carpule” in 1922, filed for a trademark, and used it for medications designed to be injected hypodermically. Some ads boasted that “In the Cook ‘CARPULE’ System, the mechanical aspects of Dental Anesthesia have been reduced to Scientific Simplicity.” Others described “a whole system of hypodermic anesthesia, perfected and simplified, with the medication in the Carpule—a glass cartridge, which insures its being as pure, accurate and active at the moment of injection as it was at the moment of manufacture.” The form was designed by Harvey Samuel Cook (1888-1924), a physician in Valparairso, Ind. who assigned his several patents to Cook Laboratories. The inscription on this example reads ““N. 107-D COOK LAB INC. CHICAGO / PATENTED.”
