<p>PROBLEM TO BE SOLVED: To make a paper partition capable of material saving easy to be used. SOLUTION: A first partition plate 1 and/or a second partition plate 11 forms side indentations 20a at lower parts of both side portions. Its upper part is formed with side protrusions 21a. When the side indentations 20a and side protrusions 21a are arranged side by side on the planes of the first and/or second partition plates 1, 11 in such a way that their up-side-down states are faced opposite to each other, the side protrusions 21a formed at side portions of the adjoining separate first and/or second partition plates 1, 11 are formed such that they may be fitted to the side indentations 20a formed at the adjoining first partition plate 1 and/or second partition plate 11.</p> |
