<P>PROBLEM TO BE SOLVED: To improve the handleability of a collapsible container by forming grips also on long side boards of the container without impairing its strength. <P>SOLUTION: According to the collapsible container A, a support projection 3 is formed at least on each four corner of a bottom board 1 having four sides, while intermediate support projection 5 is formed between both ends of each opposed long side of the bottom board. An incision 13, into which the intermediate support projection 5 is fitted loosely, is formed on the lower side of each long side board 10, which is pivoted on the long side of the bottom board 1 to be folded down inward, while each short side board 7 is pivoted on each opposed short side of the bottom board 1 to be folded down inward. The support projections 3 and intermediate support projections 5 bear a plurality of small collapsible containers B in a horizontal low to stack them on the container A. A frame-shaped reinforcing rib 12 is formed on the peripheral edge of the outer surface of each long side board 10, and reinforcing vertical ribs 14 are formed above the incision 13 on the above outer surface. On the part of the reinforcing rib 12 that is formed along the upper edge of the outer surface of each long side board 10, the pocket-shaped grips 15 open downward are formed by the vertical rib 14 with each split grip 15 having a width W to allow a finger to come in. <P>COPYRIGHT: (C)2004,JPO |
