PCT No. PCT/US96/15690 Sec. 371 Date Apr. 13, 1998 Sec. 102(e) Date Apr. 13, 1998 PCT Filed Oct. 1, 1996 PCT Pub. No. WO97/13707 PCT Pub. Date Apr. 17, 1997A plastic container (liner) that fits closely inside a conventional aerosol can to provide protection for the can. The completed liner/container and can assembly is filled with, e.g., an acidic detergent composition and aerosol propellant. Inwardly curved channels are provided linearly down the sides of the plastic container to allow air to escape when the plastic liner/container is inserted into the body of the aerosol can before the top is added to the can. The plastic container is molded into a collar around the valve opening in the top of the can after the top is attached to the body to form a "pre-assembly" container that is then filled. An acid compatible valve assembly is attached through the valve opening to seal the can, and propellant is added. |
