<p><P>PROBLEM TO BE SOLVED: To provide a box, in which a box body and a lid are formed integrally, and whose capacity can be changed optionally while the storage and transfer efficiencies of the box is maintained when the box is used with its lid separated. <P>SOLUTION: The box is of an almost square pillar shape, and comprises a polygonal bottom, a top opposite to the bottom, and side faces connecting the edge of the bottom to that of the top. A plurality of separating belts encircling the side faces are formed on them with a prescribed distance formed between each belt. The box can be separated into a bottom side portion and a top side portion via any of the separating belt. In the bottom side portion, a part having the bottom and side faces with the separating belt forming an opening is made into a trunk, while a part of the top side portion having the top and side faces with the separating belt forming an opening is made into a lid. When the lid and the trunk are made, a folding part is formed along the opening at any of the corners of the trunk, where the folding part is marked off by a reverse-tapered folding line formed on the side faces of the trunk that makes it possible to fold a part of the corner and the side face of the trunk toward its exterior. <P>COPYRIGHT: (C)2004,JPO</p> |
