Method of making a metallic container

摘要

There is provided a method of making a metallic container having a predetermined or standard height and a circumferential seam of the type which is formed by fitting a first open end portion of an upper can body having a venting portion and a second open end portion of a lower can body having a bottom portion to each other with a heat sealable adhesive layer therebetween to form a metallic container preform having a fitted portion, and heating the fitted portion thereby to fuse the adhesive layer. The container preform is placed between a first member and a second member which are oppositely disposed with a predetermined distance therebetween, such that the venting portion faces the first member and the bottom portion faces the second member, then the fitted portion is heated, simultaneously the internal pressure of the container preform is allowed to enhance, and the axial outward slip between the first and second open end portions through the fused adhesive layer which is caused by the elevated internal pressure, is suppressed by the first and second members.
