The use of aerosol cans entails the spray-emission of propellant. Even newer, presumably ozone-friendly alternative propellants are dangerous because they are labile compounds that can be broken down into their basic substances as a result of insolation. They are combustible and even explosive when combined with solvents and otherwise constitute an ecological burden. The new package is designed to permit a more judicious use of resources than in the past and to help reduce the ecological burden on the environment. A substance container (2) made of a rubber material forms an inner container which is situated inside a pressure-maintaining outer container (3) made of a rubber material. As it is filled the substance container and along with it the outer container (3) are expanded. A pressure chamber (4) between fill container (2) and outer container (3) is provided to enable the fill container (2) to be emptied as completely as possible. The package has the advantage that - although the fluid substance is pressurized and thus can be dispensed very conveniently - no environmentally burdensome propellant is required. In the long run fewer resources are needed for using the package as a dispenser. |
