In addition, if the terms "first", "second", etc. appear in the description of the present invention, they are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0020] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] As shown in the accompanying drawings, the present invention includes an outer box 1 and a plurality of inner boxes 2 stacked in sequence in the outer box 1. The inner box 2 includes a bottom box 3, a cover 4 and a connecting sealing cardboard 5. The bottom box 3 and the cover 4 are respectively bonded to one end of the connecting sealing cardboard 5, and the cover 4 can be flipped and installed on the top of the bottom box 3 through the connecting sealing cardboard 5. The bottom box 3 and the cover 4 are connected and locked by the other end of the connecting sealing cardboard 5. A group of cavities 6 are horizontally provided on the bottom box 3 and the cover 4, and an egg tray 8 is provided in the cavity 6.

[0022] The top of the outer box 1 is open, and handles 15 that fold inward are provided on the left and right sides of the opening. Locking plates 16 that fold inward and fix the two handles 15 are provided on the front and back ends of the opening. The internal length of the outer box 1 is the same as the length of the inner box 2, and the internal width of the outer box 1 is twice the width of the inner box 2, that is, two inner boxes 2 can be stacked horizontally in the outer box 1, and after stacking, the inner box 2 is in a fixed state and will not shake.

[0023] The eggs are clamped in place from above and below by egg trays 8 on the bottom box 3 and lid 4. A connecting seal 5 connects the bottom box 3 and lid 4 on one side, while the movable end of the connecting seal 5 is inserted into the lid 4 from the other side, locking the bottom box 3 and lid 4. In this case, the bottom box 3 and lid 4 are identical in length and width, with the lateral width of the connecting seal 5 being smaller than the length of the bottom box 3. When secured, the rear side of the bottom box 3, the rear side of the lid 4, and the bottom are bonded to the connecting seal 5, respectively. The other end of the connecting seal 5 serves as a movable member for opening and locking.

[0024] Furthermore, both sides of the upper portion of the cover 4 are provided with inwardly folded recesses 10, and the width of the cover 4 above the recesses 10 is smaller than the width of the lower portion of the cover 4. The recesses 10 can be used as finger grips for taking and placing inner boxes. When the inner boxes are stacked, a gap is formed between the horizontal positions of the tops of the inner boxes, making it easy for fingers to reach in and quickly remove them.

[0025] Furthermore, a plug-in hole 11 is provided in the recessed portion 10 on the open side of the cover 4 to match the movable end of the sealing paperboard 5 .

[0026] Furthermore, the bottom box 3 and the cover 4 are both double-layer hollow structures, and two adjacent cavities 6 are separated by a double-layer hollow partition 13. The double-layer hollow structure has good shock and impact resistance, preventing eggs from being broken by collision.

[0027] Preferably, the egg tray 8 is cut from a cardboard and bonded to the top of the cavity 6 in one piece.

[0028] When cutting, cut from the midpoint to the four corners respectively, so that the cardboard has four scattered slits. When the middle part of the cardboard is subjected to external force, it can be concave downward to form a semi-open cavity. When cutting, the positions near the four corners are not cut, so that the egg tray can have space to expand outward after the egg is squeezed, making the egg and egg tray fit more tightly.

[0029] Preferably, the cavity 6 is square, and the depth of the cavity 6 is less than half the width of the cavity 6 .

[0030] In this case, the top of the egg tray 8 is flush with the top of the cavity 6. When the triangular blocks cut from the egg tray 8 are bent inward, the maximum bending angle is that one corner of the triangular block touches the bottom of the cavity 6, and the entire block will not fold onto the side wall of the cavity 6, and can always maintain a conical egg tray shape.
