DETAILED DESCRIPTION

[0043] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The first aspect of this embodiment provides a packaging structure, such as Figure 1 , Figure 2 As shown, it includes a packaging structure body, the packaging structure body is provided with a placement area, and an egg accommodating groove 21 and a support column 22 are provided in the placement area, and the upper surface height of the support column 22 is equal to the height of the upper surface of the packaging structure body; located at the periphery of the placement area, the packaging structure body is provided with symmetrical connecting grooves 40 and connecting bosses 30, the upper surface height of the grooves is lower than the upper surface height of the packaging structure body, and the upper surface height of the connecting bosses 30 is higher than the upper surface height of the packaging structure body.

[0046] After the two packaging structure bodies are connected through the connection groove 40 and the connection boss 30, the upper surfaces of the two packaging structure bodies are in contact with each other, and the support columns 22 of the two packaging structure bodies are supported one by one. Preferably, the connection groove 40 is adapted to the connection boss 30, that is, after the connection boss 30 is connected to the connection groove 40, the outer surface of the connection boss 30 is in contact with the inner surface of the connection groove 40; this can further prevent lateral slippage and further avoid deformation of the packaging structure body caused by extrusion.

[0047] It should be noted that if Figure 1 As shown, the upper surface of the connecting column is shown at a, the upper surface of the packaging structure body is shown at b, the upper surface of the connecting groove 40 is shown at c, and the upper surface of the connecting boss 30 is shown at d.

[0048] The packaging structure in the present invention is used as both the upper box and the lower box of the egg packaging box, so the packaging structure is lower than the existing lower box; because the height of the upper surface of the support column 22 is consistent with the height of the upper surface of the packaging structure body, the support column 22 is also lower than the support column 22 of the existing lower box, so that the area of ​​the upper surface of the support column 22 is larger. When the support columns 22 support each other one by one, they can provide greater supporting force and the structure is more stable.

[0049] In some embodiments, Figure 3 As shown, the connecting groove 40 includes a first groove segment 41, a second groove segment 42 and a third groove segment 43, wherein the first groove segment 41 is arranged on the first side 11 of the packaging structure body, the second groove segment 42 is arranged on the second side 12 of the packaging structure body, and the third groove segment 43 is arranged on the third side 13 of the packaging structure body; Figure 4 As shown, the connecting boss 30 includes a first boss segment 31, a second boss segment 32 and a third boss segment 33, wherein the first boss segment 31 is disposed on the first side 11 of the packaging structure body, the second boss segment 32 is disposed on the fourth side 14 of the packaging structure body, and the third boss segment 33 is disposed on the third side 13 of the packaging structure body;

[0050] The first side 11 , the second side 12 , the third side 13 and the fourth side 14 are respectively four sides of a rectangle, the first side 11 and the third side 13 are opposite to each other, and the second side 12 and the fourth side 14 are opposite to each other.

[0051] In some embodiments, Figure 3 As shown, one end of the second groove segment 42 is connected to the first groove segment 41, and the other end is connected to the third groove segment 43; Figure 4 As shown, one end of the second boss segment 32 is connected to the first boss segment 31 , and the other end is connected to the third boss segment 33 .

[0052] In order to reduce the use of packaging materials, reduce costs, and improve the stability and anti-extrusion performance of the packaging structure; in some embodiments, Figure 3 , Figure 4 As shown, the egg accommodating grooves 21 are evenly arranged in rows, and the supporting columns 22 are connected between the egg accommodating grooves 21.

[0053] In order to further reduce the use of packaging materials and reduce costs, in some embodiments, such as Figure 3 , Figure 4 As shown, four egg receiving grooves 21 are arranged around the circumference of any one of the support columns 22 .

[0054] In order to further reduce the use of packaging materials and reduce costs, in some embodiments, such as Figure 3 , Figure 4 As shown, a support column 22 is connected between four egg accommodating grooves 21 in two adjacent rows of any two adjacent columns.

[0055] In some embodiments, Figure 5 As shown, a gap is provided between any two adjacent egg containing grooves 21; Figure 5 In the figure, e is the gap position.

[0056] like Figure 7 FIG. 1 is a schematic diagram of the packaging structure of this embodiment containing eggs. The figure shows that after the eggs are placed, the gap is located between the eggs, which makes it easy to take the eggs in and out.

[0057] For example, Figure 5 As shown, the direction of the figure is used for explanation. In the figure, two columns of egg accommodating grooves 21 are provided, and five rows of egg accommodating grooves 21 are provided. Three egg accommodating grooves 21 are circumferentially surrounded by one support column 22. It can be seen from the figure that the egg accommodating grooves 21 in the second row cooperate with the egg accommodating grooves 21 in the first row and the egg accommodating grooves 21 in the third row to circumferentially surround the support column 22. Such a structure can not only save materials, but also make the egg packaging box have a better supporting effect; of course, it is not limited to the examples shown in the figure. For example, it can also be that the egg accommodating grooves 21 in the first row and the egg accommodating grooves 21 in the second row cooperate to circumferentially surround a support column 22, and the egg accommodating grooves 21 in the third row and the egg accommodating grooves 21 in the fourth row cooperate to circumferentially surround a support column 22.

[0058] Furthermore, in some embodiments, the distance between the centers of two adjacent egg receiving grooves 21 (eg Figure 6 D2 shown in FIG) is not less than the first preset value, that is, it can be greater than the first preset value and equal to the first preset value; the distance between the positions where the circles at the upper end openings of two adjacent egg solute grooves 21 are closest to each other (such as Figure 6 D1) shown in the figure is not less than the second preset value, that is, it can be greater than the second preset value and equal to the second preset value; it can prevent two adjacent eggs from being squeezed and avoid egg damage. Exemplarily, the first preset value is 50mm and the second preset value is 0.14mm.

[0059] A second aspect of this embodiment provides an egg packaging box, such as Figure 8 , Fig. 9 As shown, it includes the packaging structure described above.

[0060] The third aspect of this embodiment provides a mold for manufacturing the above-mentioned packaging structure. Since the overall height of the support column 22 and the packaging structure body is reduced, mold materials are saved when manufacturing the mold, the mold is convenient to process, and the temperature is quickly transferred when manufacturing the product.

[0061] A fourth aspect of the present invention provides a method for manufacturing a packaging structure, comprising the following steps:

[0062] The packaging structure described above is obtained by pressing with the mold.

[0063] Furthermore, the packaging structure can be manufactured using plant fiber molding production technology and equipment.
