[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figures 1 to 4 As shown, the corrugated cardboard box involved in this embodiment includes a rectangular corrugated bottom plate 1. The left and right sides of the corrugated bottom plate 1 are respectively provided with first side plates 2 extending upward, and the front and rear sides are respectively provided with second side plates 3 extending upward. The second side plates 3, the first side plates 2, and the corrugated bottom plate 1 form a rectangular prism-shaped receiving cavity. The receiving cavity is provided with a grid assembly 4 to divide it. The grid assembly 4 includes at least one horizontal grid plate 401 extending left and right and at least one vertical grid plate 402 extending front and rear. The grid assembly 4 divides the receiving cavity into a plurality of receiving sub-cavities 5 arranged in a rectangular array. The lower end of each receiving sub-cavity 5 is closed by the corrugated bottom plate 1 and the upper end is connected to the outside.

[0020] The first side plate 2 is hinged with an inner cover plate 6 that can cover the left or right half of the cavity opening, and the second side plate 3 is hinged with an outer cover plate 7 that can cover the upper or lower half of the cavity opening.

[0021] Each of the accommodating cavities 5 is provided with an elastic irregularly shaped resetting mesh plate 8 on the inner cover plate. The end of the irregularly shaped resetting mesh plate 8 facing away from the accommodating cavity 5 is filled with a paper ball 9 to deform it. The paper ball 9 is located between the inner cover plate 6 and the outer cover plate 7.

[0022] Furthermore, the irregularly shaped reset mesh plate 8 includes a central plate 801, a first outer ring 802 surrounding the central plate, and a second outer ring 803 surrounding the first outer ring. A first gap (unmarked) is provided between the central plate 801 and the first outer ring 802, and a second gap (unmarked) is provided between the first outer ring 802 and the second outer ring 803. A first connecting strip 804 connecting the central plate and the first outer ring is provided in the first gap, and a second connecting strip 805 connecting the first outer ring and the second outer ring is provided in the second gap.

[0023] Furthermore, the irregularly shaped reset mesh plate 8 also includes a third outer ring 806 surrounding the second outer ring. The third outer ring 806 is integral with the inner cover plate 6. A third gap (unmarked) is provided between the second outer ring and the third outer ring. A third connecting strip 807 connecting the second outer ring 803 and the third outer ring 806 is provided in the third gap.

[0024] Furthermore, the included angle between the first connecting strip 804 and the second connecting strip 805 is 180°; the included angle between the second connecting strip 805 and the third connecting strip 807 is 180°.
