A spraying apparatus utilizes a canister which has a threaded, upwardly opening body and a threaded lid for closing the body, with the lid and body cooperating to define a chamber for receiving and clamping containers of fluid to sprayed. The containers have upwardly opening necks which carry removable caps for confining sprayable fluid during storage and transportation. When the canister lid is threaded onto the body, a fluid-containing container is compressed between the canister lid and a bottom wall of the canister body. In one embodiment, the canister lid is provided with an additional inner set of threads which receive mating threads that are formed on the neck of the container so that a seal is formed when the container neck is threaded into engagement with the canister lid. In a more preferred embodiment, a seal is formed between an upwardly facing surface of the container neck and a downwardly facing surface of the canister lid when these surfaces are clamped into engagement as the canister lid is threaded onto the canister body.
