METHOD FOR PRODUCING DOUBLE AEROSOL CONTAINER, DOUBLE AEROSOL CONTAINER, AND APPARATUS FOR PRODUCING DOUBLE AEROSOL CONTAINER

摘要

[Problem] To provide a method for producing a double aerosol container capable of maintaining the quality of an inner pouch by preventing, when the inner pouch is inserted, deformation of the inner pouch and generation of wrinkles and cracks, the double aerosol container having excellent productivity and being producible with low cost. [Solution] A method for producing a double aerosol container comprising: a metal container having a body portion and an opening and/or shoulder portion with the diameter reduced by the body portion; and an inner pouch inserted into the metal container and having a body portion and an opening, a propellant being interposed between the metal container and the inner pouch. This method includes: subjecting an upper part of a bottomed cylinder can supported on a can holder to a drawing process with a plurality of drawing dies, thereby forming a metal container; and then inserting an inner pouch into the metal container by using a dedicated inner pouch inserting device provided with an insertion rod that moves reciprocally with a predetermined speed and a predetermined pressing force.
