Development is conducted to enhance productivity by gluing the bottom of the one-touch box and to improve the distribution ef ciency upon delivery. In addition to improving productivity by eliminating the reverse folded part of the bottom, the thickness of the box when folded is reduced and help to reduce reducing the amount of space to store it. The boxes in the folded state, in which swelling is minimal, can be stacked in a stable manner, and it enables to increase the number of the boxes to be loaded on to the pallet upon delivery and reduce the size of the packing box.
