Abstract: PURPOSE: A packing box for wire winding bobbins is provided to eliminate damage or transformation by preventing the motion of bobbins in a settled state inside the packing box by installing a bobbin rest matched with the shape of the bobbins and to readily transfer the packing box by using a forklift truck as integrating a pallet. CONSTITUTION: In both covers(3a,3a') opened out, bobbins are horizontally laid to be placed on a lower rest(9') aligned on the downside of an inner box main body for being supported up by the lower rest. Herein, both flanges of the bobbins are inserted to a circular recessed groove(cg) at a lower unit rest. Due to the radius of the curvature of the recessed groove equal to an outer diameter of the flange enabling a fixed state of the bobbin put on the rest(9'), left and right motions are prevented. Thereby among the flanges of the bobbins in a settled sate, the insertion of an outer periphery is accomplished to be fixed simultaneously and motion is avoided by the rest supporting flange in the settled state that a sufficient isolating distance is kept. A pallet is integrally equipped with the packing box during the transfer of the packing box, so that the work of putting the packing box on a separate pallet is eliminated to enable easier transfer.
