<p><P>PROBLEM TO BE SOLVED: To provide a capacity-variable packaging box capable of varying its capacity by changing the height of a folded container by forming horizontal ruled lines and inclined ruled lines on a sidewall of the packaging box formed of a corrugated fiberboard or other cardboard, usable a plurality of times as a returnable container unnecessary for any other component, and capable of storing, keeping or returning interior parts such as a shock-absorbing material and a fixing material in the container after use. <P>SOLUTION: Two horizontal ruled lines of different heights from a bottom face are formed in all four peripheral wall surfaces (front surface, back surface, and right and left surfaces) forming the bottom surface part. An inclined ruled line which is elevated at an angle of 45°from the intersection of the lower horizontal ruled line and the wall surface corner, and reaches a top surface side across the higher horizontal ruled line is formed in a set of wall surfaces opposite to each other (for example, right and left surfaces) in a similar manner. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
