ABSTRACT:
A double-walled aerosol spray container includes a hollow outer jacket and a flexible bag therein. A substance to be sprayed is held in the bag, while a propellant is charged into a space outside of the bag and within the jacket. The construction of the aerosol spray container helps ensure that the bag does not slip off during manufacture or use thereof. The bag includes a flange about its open end, and the flange abuts an inwardly projecting engagement ridge formed on a corresponding part of the jacket, preferably with an annular packing therebetween. The bag has a storage section that is thinner than the flange, and is easily deflatable or deformable. The aerosol spray container also includes a housing in which a spray valve mechanism is incorporated. The housing includes an inner frame that is inserted into the open end of the bag so that the bag is securely held between the jacket and the housing.
