Abstract

The invention relates to a canister comprising a first container (concentrate chamber) holding a concentrate, and a second container (solution chamber) holding a ready-to-use solution constituted by mixing a concentrate and a diluting fluid. According to the invention, the two containers of the canister are configured as chambers of the canister, connected to each other by a fluid jet pump, and can be operated from one side. Both the filling device of the concentrate chamber and the dispensing device of the chamber holding the ready-to-use solution are fitted with coded access control devices. The chambers are arranged partially above each other. The concentrate filling device and the fluid jet pump include a suction pipe and mixture outlet arranged in a canister lid.
