<p>PROBLEM TO BE SOLVED: To provide a tray made of a synthetic resin wherein a doubly folding operation can be naturally and easily performed, and the reduction of refuse can be surely accomplished. SOLUTION: Two doubly folding line sections 12, 12 which are in parallel with each other are formed across a location being located on the approx. central line of the bottom section 11 of this tray 10 made of a synthetic resin, by which respective corner sections can be superposed with each other when the tray 10 made of a synthetic resin is doubly folded. Then, when the tray 10 made of a synthetic resin is doubly folded with these doubly folding line sections 12, 12 as the center, respective corner sections are made superposable with each other.</p> |
