Rechargeable spray cam using carbon di:oxide cartridges - allows refilling of cam with fluid contents to reduce material waste

摘要

The spray can may be refilled after use, and uses a CO2 cartridge to power the spray. On pressing down the spray head (13) the control rod (2) presses on a membrane (1) to open up the path for the propellant which passes into the can (15) to expel the fluid through a tube and nozzle. The replaceable gas cartridges fit in a recess in the base of the can. ADVANTAGE - Less waste of raw materials by making the spray can reusable.
