<p><P>PROBLEM TO BE SOLVED: To provide a non-bulky packaging container which has a minimized thickness in a pre-assembled flat state in the packaging container assembled into a box by raising wall sections from the pre-assembled flat state and having an opened upper part. <P>SOLUTION: In a shape of a packaging container in a pre-assembled flat state, a left-wall joint piece 10c and right-wall joint piece 10d are joined to a bottom plate 1, a left wall section 2c and right-wall section 2d are folded on each other on the bottom plate 1 by folding-back them at a left bottom crease 3c and right bottom crease 3d, a left frame edge 7c and right frame edge 7d are not in a stretched standing state, the left frame edge 7c is overlapped with a left inner plate 8c together with a left outer plate 4c in a frame edge inner plate overlapping state, and the right frame edge 7d is overlapped with a right inner plate 8d together with a right outer plate 4d in a frame edge inner plate overlapping state. Further, the maximum external falling state of the left wall section 2c and right wall section 2d is equal to the maximum opening slant falling state which does not reach to a horizontal falling state equal to the bottom plate 1, a front outer plate left-side joint section and front outer plate right-side joint section are joined with a front outer plate 4a, and a rear outer plate left-side joint section and rear outer plate right-side joint section are joined with a rear outer plate 4b. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
