Title: SEAMLESS CONTAINER, PRODUCTION METHOD THEREFOR, COMPOSITE CONTAINER, AND METHOD FOR PRODUCING SAME
Abstract:
Provided are: a lightweight, space-saving metal seamless container that can be mounted to a space rocket, wherein a metal container body having a convex surface shape such as a spherical shape is seamless, and the container body and a port are formed so as to be seamlessly integrated; a composite container; and production methods for the seamless container and the composite container. The problem addressed by the present invention is solved by a seamless container comprising: a container body that is made from a metal material, has no cylindrical body section or in which the length of a body section is ½ or less of the diameter of said body section, is seamless, and has a convex surface shape; and a port that is made from a cylindrical metal material and attached to the container body. The container body has an outer diameter of 50-1,000 mm. The port is seamlessly integrated with the container body and has an outer diameter of 5-200 mm and a wall thickness equal to or greater than the wall thickness of the container body.
