With a device for spraying fluid substances with an outer container, a separate inner product container with a spray head and a propellant means spraying the product, the aim is to make possible an environmentally friendly and safe spraying of fluid substances. This is achieved in that the propellant means is conceived as a gas-filled, compressible vessel (7) which is essentially non-pressurised in the initial state and is allocated to the compressible product container (5) and in that a self-closing tap water coupling (4) is provided on the outer container (3). <IMAGE>
