In order to be suitable for stacking, the appearance of the plastic turnover box is designed to be in a straight state, namely the opening surface and the bottom surface are all of equal width. Therefore, after the turnover box is used for loading fruits and vegetables, the fruits and vegetables can be stacked one by one in a bottom stacking direction, and the storage and the transportation are convenient.
However, when the turnover box is stored and transported in an empty box state, the turnover box wastes space in a mode of stacking the turnover boxes one by one in a bottom-to-top mode, the turnover box is inconvenient to store and transport, and the storage and transport cost is high. Therefore, in order to save storage and transportation space, the best processing mode is to nest the turnover boxes one by one, but the turnover boxes cannot be correspondingly nested due to the straight body design of the turnover boxes. Therefore, in a factory, an operator usually folds the upper and lower cases in a reverse direction as shown in fig. 1 or 2, inserts a laterally upright case in the middle, forms a three-in-one combination, and stacks one set of cases.
