TRANSFORMED SEAMLESS CAN AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a transformed seamless can that is hard to buckle when load is applied in the direction of its body height, and that does not buckle from a tapered part by axial load at the time of wind-fastening. SOLUTION: The transformed seamless can 1 comprises a body part 2 that is constituted of an upper part 2a having a cylindrical form and a lower part 2b having a form of a frustum of a reverse cone, with a thick-wall part 2f being provided at the border portion between the upper part 2a and the lower part 2b or in the vicinity thereof. The can is also characterized in that the lower part 2b is bent inward or in a tapered state.
