Claim:
A reinforced transportation container that is comprised of a transportation container ( 20 ) formed of resin and a metal reinforcement fitting ( 10 ) which is attached to a bottom of the transportation container ( 20 ), wherein: the transportation container ( 20 ) is formed of resin and in an approximate box shape of which upper side is opened as an opening ( 20 a ), and the upper side flange ( 21 ) is provided on sides of the upper side of the transportation container ( 20 ) and a bottom side flange ( 22 ) is provided on sides of the bottom side of the transportation container ( 20 ), the upper side flange ( 21 ) is projecting outward continuously from the opening ( 20 a ) for a predetermined length, and surrounding the peripheral edge of the opening ( 20 a ), and the bottom side flange ( 22 ) is projecting outward by the same length as that of the upper side flange ( 21 ), and surrounding the peripheral edge of the bottom side of the transportation container ( 20 ) so that when same kind of transportation containers ( 20 ) are stacked, the sides and the bottom ( 20 b ) lower than the bottom side flange ( 22 ) of a upper transportation container ( 20 ) are inserted into the opening ( 20 a ) of a lower transportation container ( 20 ), and the upper surface of the upper side flange ( 21 ) of the lower transportation container ( 20 ) abuts with the lower surface of the bottom side flange ( 22 ) of the upper transportation container ( 20 ), and the metal reinforcement fitting ( 10 ) that is attached from underneath to the bottom of the transportation container ( 20 ) is comprised of a pair of hooking parts ( 11 ) opposite each other and a strip ( 12 ), the strip ( 12 ) which is formed so as to be curved vertically upward at the center in a length direction and laid across laterally on the bottom of the transportation container ( 20 ), integrally formed with the pair of hooking parts ( 11 ), connects the hooking parts ( 11 ) facing toward each other, and the length of the strip ( 12 ) approximately equals that of the transportation container ( 20 ) in the short-side direction, and the hooking parts ( 11 ) extending upward in a strip shape along the side of the transportation container ( 20 ) from the bottom side, and each having an end ( 11 a ) that has a hook-shaped cross section so as to be capable of hooking with each of the bottom side flanges ( 22 ) when the strip ( 20 ) is attached to the bottom surface of the transportation container ( 20 ).
