PROBLEM TO BE SOLVED: To provide a method for assembling a container so as not to cause a pressure gradient in a circular gap formed between an outer tube and an inner tube. SOLUTION: The outer tube is prepared, which includes a clogged bottom part; an open top; and a side wall between them, and where the side wall partitions the inner surface from the outer surface. A spacing element, which comprises a penetrating center opening; and a member protruded to the inner part of the open top of the outer tube, is adjacently arranged to the open top. The inner tube is prepared, which includes a clogged bottom part; an open top; and a side wall between them and where the side wall partitions the inner surface and the outer surface. The inner tube is inserted to the outer tube through the center opening of the spacing element, so as to form a circular gap between the outer tube and the inner tube. During assembling, a part of the spacing element is protruded to a part between the inner surface of the outer tube and the outer surface of the inner tube, so as to vent air from the circular gap to be atmospheric pressure during a time till the inner tube is inserted to the outer tub.
