Title: Manufacture of pressure container
Inventor: HAMAGUCHI MASAMI
IPC: B21D51/24
Filed: 1987-12-26
Abstract: PURPOSE:To improve the sealing performance of a container by fitting a bottom plate by coating an adhesive on the inner periphery of the lower end of a cylindrical body and infilterating the adhesive in the gap between the bottom plate and cylindrical body by temporarily applying a high pressure at the inner part of the cylindrical body. CONSTITUTION:The bottom plate 2 having a skirt part 21 is fitted by coating an adhesive 3 annularly on the whole periphery of the inner face of the lower end releasing part 11 of a cylindrical body 1. A fixed pressure difference is then given via the air pressure of from a pressure source to the inner and outer parts of the assembly body of the cylindrical body 1 and bottom plate 2. When the pressure giving time is continued by the specified time, the adhesive 3 aggregated at the upper end part of the skirt part 21 is filled up by its infilteration into the small gap between the cylindrical body 1 and skirt part 21. The cylindrical body 1 and the skirt part 21 of the bottom plate 2 are completely stuck and the sealing performance of the product container is thus improved.
