PROBLEM TO BE SOLVED: To reserve a space for preventing contact between an outer container and an inner container when the inner container is inserted into an end of a body part of the outer container body.SOLUTION: The inner container 1 is inserted into the outer container body 15, where an inner cylinder opening 3 is inserted first into the end 18 of the body part 14 of the outer container body 15 formed in a shape of a straight pipe, with center lines 11 aligned nearly. The inner cylinder opening 3 and an outer cylinder opening 12 are fitted. Then, the end 18 side of the body part 14 is externally fitted to a first reduced diameter cylinder 22 formed on the end 18 side of a peripheral rise part 19. The inner container 1 may be inserted into the outer container body 15 and assembled, while the risk of a surface contacting the end 18 may be reduced since the end 18 of the outer container body 15 is fully open without a reduction in diameter. |
