<p><P>PROBLEM TO BE SOLVED: To provide a double container capable of firmly holding an inner container within an outer container having a polygonal shape in cross sectional view and easily removing the inner container during removal of the inner container and having superior operability. <P>SOLUTION: A fixation member 4 includes: an engagement member 41 detachably engaged with an outer container 3; and a rotating member 44 disposed rotatably around a container axis O of an inner container 11 relative to the engagement member 41. The engagement member 41 includes engagement pieces 46 elastically deformable in the radial direction perpendicular to the container axis O direction and engaged with the outer container 3 from the radial direction. The rotating member 44 includes pressing projections 71 projecting from the side opposite to the outer container 3 toward the engagement member 41 side sandwiching the engagement member 41 in the radial direction. The rotating member 44 is rotatable about the container axis O between a pressing position where the pressing projections 71 are overlapped with the engagement pieces 46 in the radial direction to restrict deformation of the engagement pieces 46 and a release position where restriction of the deformation of the engagement pieces 46 is released. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
