<p><P>PROBLEM TO BE SOLVED: To provide a paper box which can store a remaining content by reducing a volume accompanying the decrease in the content. <P>SOLUTION: In the paper box prepared by connecting each a pair of end boards 2 and a pair of side boards 3 on the periphery of a bottom board 1, and connecting adjoining end boards 2 and side boards 3, two parallel transversely foldable ruled lines 5 are made on the middle part of the bottom board 1 over between both side edges, and crest-folding ruled lines 6 and valley-folding ruled lines 7 are alternately arranged so that distances are widened in a V-shape from both ends of each transversely foldable ruled line 5 to the end edges of a pair of the side boards 3. When the content is decreased, the bottom board 1 is folded along the transversely foldable ruled line 5, and both side boards 3 are folded along the crest-folding ruled line 6 and the valley-folding ruled line 7, and the end boards 2 are piled up together to reduce the volume to a half or less, and to store the remaining content under a non-bulky condition. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
