<P>PROBLEM TO BE SOLVED: To provide a collective packaging container for rolled photo-sensitive material capable of stacking-up more than two stages without collapsing the stacked-up material and capable of improving a transporting adaptability. <P>SOLUTION: When collective packaging containers 10 having rolled photo-sensitive material stored therein are stacked up by more than two stages, a first protrusion 34 formed continuously from both ends toward a longitudinal direction at an outer wall of a bottom plate 16 of an upper stage container main body 10 is engaged with a recess 38 at a lower stage partition plate 14 and also engaged with between inner walls of an upper edges of side plates 18, 20 at the lower stage container main body 12. When the upper stage container main body 10 is apt to move in a longitudinal direction with an arbitrary external force, both end surfaces of the first protrusion 34 of the upper stage container main body 10 and interference parts 46 at the inner walls of the side plates 18, 20 of the lower stage container main body are interfered to each other and in turn, when the lower stage container main body 10 is apt to move in a width-wise direction, a side surface of the first protrusion 34 and a partial interference part 48 at an inner wall of the recess 38 of a lower stage partition plate 14 are interfered to each other so as to restrict motions of the upper stage container main body in a longitudinal direction and a width-wise direction. <P>COPYRIGHT: (C)2003,JPO |
