The present invention relates to a pouch-shaped case forming apparatus for forming a pouch-shaped case having a terrace step, wherein there are no dents or wrinkles at a pouch folding portion of the pouch-shaped case, a method of manufacturing a pouch-shaped case using the same, and a pouch-shaped case manufacturing using the forming apparatus.

Method for producing an aerosol dome having a dome region with an upwardly adjoining rolled rim arranged at an upper passage opening and with a downwardly adjoining flange region with an everted portion. An intermediate stage is prepared in one or more stages from a lacquer-coated blank (R), the intermediate stage having the upper passage opening, followed downwardly by a neck portion, then followed by the dome region, which is followed by an encircling straight flange. The intermediate stage is processed in a processing stage (S9) in which only the everted portion is formed.

A mold is for press molding a metal plate and a resin material to produce a metal-resin composite. The mold includes an upper mold and a lower mold that sandwich the metal plate and the resin material. A cavity for arranging the resin material is provided by the upper mold and the lower mold. The upper mold has a recess into which the resin material leaking from the cavity is caused to flow.

A mold for producing a metal-resin composite by press-forming a metal member and integrally molding the metal member that is press-formed and a resin material includes an upper mold and a lower mold that sandwich the metal member and the resin material. The upper mold includes a first press surface for press-forming the metal member and a second press surface for integrally molding the metal member and the resin material. A distance between the first press surface and the lower mold is shorter than a distance between the second press surface and the lower mold.
