[0033] The box body 10 surrounds the first accommodating groove 11, and the first accommodating groove 11 is used for accommodating the product inner holder 20, and the box body 10 is used for supporting the product inner holder 20.

[0034] The inner holder main body 21 is used for supporting a product, and the inner holder main body 21 can also limit the position of the product to prevent the product from moving in the first accommodating groove 11. The inner holder main body 21 is accommodated in the first accommodating groove 11, that is, the inner holder main body 21 does not exceed the groove opening of the first accommodating groove 11.

[0035] The side plate structure 22 comprises a plurality of inner holder side plates 221, that is, the side plate structure 22 comprises two or more inner holder side plates 221. The inner holder side plate 221 is connected to the edge of the inner holder main body 21, that is, the inner holder side plate 221 is connected to the edge of the inner holder main body 21 close to the side wall of the first accommodating groove 11, and the inner holder side plate 221 is arranged adjacent to the side wall of the first accommodating groove 11. The inner holder side plate 221 extends out of the first accommodating groove 11, that is, the inner holder side plate 221 extends from the first accommodating groove 11 to the direction close to the groove opening of the first accommodating groove 11, and extends from the first accommodating groove 11 into the second accommodating groove 31, and the two parts of the inner holder side plate 221 are located in the first accommodating groove 11 and the second accommodating groove 31 respectively, which can hinder the relative movement of the box cover 30 and the box body 10 in the direction perpendicular to the first direction Z. The two inner holder side plates 221 are oppositely arranged, that is, in a direction perpendicular to the first direction X, the two inner holder side plates 221 are arranged on the two sides of the inner holder main body 21 respectively. Optionally, the side plate structure 22 is integrally formed with the inner holder main body 21, which can improve the manufacturing efficiency.

[0036] The box cover 30 surrounds a second containing groove 31, and the box cover 30 and the box body 10 can separate the product from the external space and protect the product. The second containing groove 31 is oppositely arranged with the first containing groove 11 along the first direction Z, that is, the second containing groove 31 is arranged along the first direction Z, and the groove opening of the second containing groove 31 is opposite to the groove opening of the first containing groove 11. The depth direction of the first containing groove 11 and the second containing groove 31 is the same as or close to the first direction Z.

[0037] The second containing groove 31 has a first end 311 and a second end 312 oppositely arranged along the first direction Z. The second end 312 is arranged on the side of the first end 311 away from the first containing groove 11 along the first direction Z, that is, the first end 311 and the second end 312 are two ends of the second containing groove 31 along the depth direction. The first end 311 is the groove opening of the second containing groove 31, and the second end 312 is the groove bottom of the second containing groove 31.

[0038] In the direction perpendicular to the first direction Z, the size of the first end 311 to the second end 312 of the second containing groove 31 gradually decreases, that is, along the first direction Z from the first end 311 to the second end 312, the size of the second containing groove 31 in any direction perpendicular to the first direction Z gradually decreases. The distance between the side wall of the second containing groove 31 and the inner support side plate 221 in the opposite direction of the two inner support side plates 221 gradually decreases. After the side wall of the second containing groove 31 contacts the inner support side plate 221, the side wall of the second containing groove 31 abuts against the inner support side plate 221, which can block the movement of the inner support side plate 221 relative to the side wall of the second containing groove 31. Since the box cover 30 and the box body 10 are packaged together at the factory, the inner support side plate 221 can remain stable relative to the box body 10 and the box cover 30. The side wall of the second containing groove 31 abuts against the inner support side plate 221, that is, the side wall of the box cover 30 abuts against the inner support side plate 221.

[0039] In the direction perpendicular to the first direction Z, the size of the end of the side plate structure 22 towards the box cover 30 can be greater than the size of the first end 311, or can be less than or equal to the size of the first end 311.

[0040] When packaging the product, the product inner support 20 is placed in the first containing groove 11, then the product is placed in the product inner support 20, and then the box cover 30 is covered. The side wall of the second containing groove 31 abuts against the inner support side plate 221 and presses the inner support side plate 221 towards the center of the side plate structure 22. After covering the box cover 30, the box body 10 and the box cover 30 are packaged together using a plastic sealing film. The box cover 30 and the box body 10 are fixed relative to each other. The box cover 30 abuts against the product inner support 20 along the first direction Z on the box body 10. The product inner support 20 remains stable in the first containing groove 11 and the second containing groove 31.

[0041] When the packaging box 100 is opened, the plastic film outside the packaging box 100 is first removed, then the box cover 30 is taken off, and the packaging box 100 is opened; under the action of the gravity of the product, the product inner holder 20 does not move with the box cover 30.

[0042] The packaging box 100 provided by the embodiment of the application comprises a box body 10, a product inner holder 20 and a box cover 30, the product inner holder 20 can accommodate and protect the product, and the box cover 30 and the box body 10 can separate the product and the product inner holder 20 from the external space and protect the product. The second accommodating groove 31 is arranged in the box cover 30, the size of the first end 311 to the second end 312 of the second accommodating groove 31 gradually decreases, when the box cover 30 is closed, the distance between the sidewall of the second accommodating groove 31 and the inner holder side plate 221 in the direction opposite to the two inner holder side plates 221 gradually decreases, so that the sidewall of the second accommodating groove 31 can stably abut against the inner holder side plate 221. By abutting the sidewall of the second accommodating groove 31 against the inner holder side plate 221, the product inner holder 20 can be prevented from moving greatly in the first accommodating groove 11 and the second accommodating groove 31, and no connecting structure is arranged between the product inner holder 20 and the box body 10 and the box cover 30, so that the product inner holder 20 can be conveniently detached from the box body 10, and the structure of the packaging box 100 is simplified; the embodiment of the application can solve the technical problem that the structure of the packaging box is relatively complex.

[0043] In some embodiments, please refer to Figures 3 to 5 In the direction perpendicular to the first direction Z, the size of the one end of the side plate structure 22 towards the box cover 30 is greater than the size of the second end 312 and less than or equal to the size of the first end 311.

[0044] The one end of the side plate structure 22 towards the box cover 30 is also the one end of the side plate structure 22 along the first direction Z towards the second end 312.

[0045] The size of the one end of the side plate structure 22 towards the box cover 30 refers to the overall size of the one end of the plurality of inner holder side plates 221 towards the box cover 30, for example, if the side plate structure 22 comprises two opposite inner holder side plates 221, the size of the one end of the side plate structure 22 towards the box cover 30 is the size surrounded by the outer edges of the two inner holder side plates 221; if the side plate structure 22 comprises four inner holder side plates 221 connected in sequence and end to end, the size of the one end of the side plate structure 22 towards the box cover 30 is the size surrounded by the outer edges of the four inner holder side plates 221.

[0046] In the direction perpendicular to the first direction Z, when the box cover 30 is separated from the side plate structure 22, the size of the end of the side plate structure 22 facing the box cover 30 is less than or equal to the size of the first end 311, that is, when the box cover 30 is covered, the first end 311 of the first accommodating groove 11 can accommodate the end of the side plate structure 22 facing the first accommodating groove 11. When the box cover 30 is covered, the end of the box cover 30 facing the box body 10 is not easy to collide with the end of the side plate structure 22 facing the box cover 30. Alternatively, the size of the end of the side plate structure 22 facing the box cover 30 can also be equal to the size of the first end 311.

[0047] In the direction perpendicular to the first direction Z, when the box cover 30 is separated from the side plate structure 22, the size of the end of the side plate structure 22 facing the box cover 30 is greater than the size of the second end 312, that is, the size of the end of the side plate structure 22 facing the box cover 30 is equal to a position of the second accommodating groove 31 between the first end 311 and the second end 312, and the side plate structure 22 is abutted on the side wall of the second accommodating groove 31 between the position and the second end 312.

[0048] The beneficial effects of the embodiments of the present application are that: in the direction perpendicular to the first direction Z, the size of the end of the side plate structure 22 facing the box cover 30 is less than or equal to the size of the first end 311, and when the box cover 30 is covered, the first end 311 of the first accommodating groove 11 can accommodate the end of the side plate structure 22 facing the first accommodating groove 11, and when the box cover 30 is covered, the box cover 30 can be directly covered on the box body 10, and the packaging speed is faster. In the direction perpendicular to the first direction Z, the size of the end of the side plate structure 22 facing the box cover 30 is greater than the size of the second end 312, and when the box cover 30 is covered, the side wall of the second accommodating groove 31 can contact and press the end of the side plate structure 22 facing the box cover 30, so that the side plate structure 22 can be stably abutted on the side wall of the second accommodating groove 31.

[0049] In some embodiments, please refer to Figures 1 to 4 The plurality of inner support side plates 221 are connected in series along the circumference of the inner support body 21 and form a ring structure. That is, the plurality of inner support side plates 221 are arranged along the circumference of the inner support body 21, and the two ends of any inner support side plate 221 along the circumference of the inner support body 21 are connected with the two adjacent inner support side plates 221 respectively, forming a ring around the center line of the inner support body 21. The circumference of the inner support body 21 refers to the direction around the center line of the inner support body 21, and the center line extends along the first direction Z. Alternatively, the inner support side plate 221 can be provided as four and form a square ring structure, which is suitable for a square box body 10.

[0050] The groove wall of the second accommodating groove 31 abuts against the ring-shaped side plate structure 22, and the plurality of inner support side plates 221 are pressed towards the center of the side plate structure 22.

[0051] The beneficial effects of the embodiments of the present application are that the plurality of inner holder side plates 221 abut against the groove walls of the second accommodating grooves 31, which can increase the acting force between the box cover 30 and the side plate structure 22, make the side plate structure 22 more stable, and make the product inner holder 20 more stable; the plurality of inner holder side plates 221 are connected in a ring shape, and the inner holder side plates 221 can support each other, which can enhance the strength of the product inner holder 20.

[0052] In some embodiments, referring to Figures 3 to 5 , the inner holder side plate 221 is inclined in a direction away from the center of the inner holder body 21 along a direction close to the box cover 30.

[0053] The direction close to the box cover 30 refers to a direction close to the box cover 30 from the inner holder body 21 along the first direction Z. The inner holder side plate 221 away from the center of the inner holder body 21 refers to that, in the arrangement direction of the inner holder side plate 221 and the center of the inner holder body 21, the inner holder side plate 221 is away from the center of the inner holder body 21. In the arrangement direction of the inner holder side plate 221 and the center of the inner holder body 21, the side walls of the second accommodating grooves 31 adjacent to the inner holder side plate 221 are located on the side of the inner holder side plate 221 away from the center of the inner holder body 21. The inner holder side plate 221 is inclined in a direction away from the center of the inner holder body 21, that is, along the direction close to the box cover 30 from the inner holder body 21 along the first direction Z, the inner holder side plate 221 gradually approaches the side walls of the second accommodating grooves 31 along the arrangement direction of the inner holder side plate 221 and the center of the inner holder body 21. In the arrangement direction of the inner holder side plate 221 and the center of the inner holder body 21, the side walls of the second accommodating grooves 31 adjacent to the inner holder side plate 221 are close to each other, which further reduces the distance between the end of the inner holder side plate 221 along the first direction Z towards the box cover 30 and the side walls of the second accommodating grooves 31.

[0054] The beneficial effects of the embodiments of the present application are that the inner holder side plate 221 is inclined, which can reduce the distance between the end of the inner holder side plate 221 along the first direction Z towards the box cover 30 and the side walls of the second accommodating grooves 31 adjacent to the inner holder side plate 221, and the inner holder side plate 221 can also abut against the side walls of the second accommodating grooves 31 in the first direction Z, which can reduce the size of the inner holder side plate 221 and facilitate the production of the product inner holder 20.

[0055] In some embodiments, referring to Figures 2 to 5 , the product inner holder 20 is movably arranged in the first accommodating groove 11, and a gap is arranged between the product inner holder 20 and the groove wall of the first accommodating groove 11.

[0056] The product inner holder 20 is placed on the bottom wall of the first accommodating groove 11, and a gap is provided between the product inner holder 20 and the first accommodating groove 11, that is, the product inner holder 20 can move in the direction perpendicular to the depth direction of the first accommodating groove 11. When the side plate structure 22 is resisted by the side wall of the second accommodating groove 31 at one end of the first direction Z and cannot move, the product inner holder 20 can be deformed to make the inner holder body 21 move in the second accommodating groove 31.

[0057] The product inner holder 20 can move in the first accommodating groove 11 when the packaging box 100 is impacted, so that the force between the product inner holder 20 and the product is reduced, and the buffering protection is enhanced.

[0058] In some embodiments, referring to Figures 3 to 5 , the packaging box 100 comprises a limiting inner holder 40 arranged in the second accommodating groove 31, the limiting inner holder 40 is connected to each groove wall of the second accommodating groove 31 to strengthen the box cover 30, and the limiting inner holder 40 is resisted by the end face of the inner holder side plate 221 away from the inner holder body 21 along the first direction Z.

[0059] The limiting inner holder 40 is connected to each groove wall of the second accommodating groove 31, that is, the limiting inner holder 40 is connected to each inner wall face of the box cover 30, which can strengthen the box cover 30. The end of the limiting inner holder 40 close to the inner holder side plate 221 along the first direction Z resists the inner holder side plate 221 on the box body 10, which can prevent the product inner holder 20 from moving along the first direction Z. The limiting inner holder 40 surrounds the slot opening to form a slot structure facing the product inner holder 20, which can accommodate the product. Optionally, the end of the limiting inner holder 40 opposite to the product inner holder 20 along the first direction Z can resist the product to keep the product stable. Optionally, the limiting inner holder 40 is bonded on the box cover 30, and the connection is more firm.

[0060] The limiting inner holder 40 can strengthen the box cover 30 and improve the protection effect of the box cover 30.
