[0028] Reference below Figures 1 to 4 A box body with a reinforced structure according to an embodiment of the present invention is described. The box body can be used as a bottom box or a box cover.

[0029] The opening of the box body 100 is set to face upward.

[0030] like Figure 1 、 Figure 2As shown, the box body with a reinforcement structure according to an embodiment of the present invention includes: a box body 100, the box body 100 includes a concave cavity 101 forming a cavity, and an inward convex reinforcement structure 102 protruding toward the inner side of the box body 100 is provided at the corner position of the concave cavity 101, and a convex structure 103 facing the outer side of the box body 100 is formed between the inward convex reinforcement structures 102 at the two adjacent corner positions. By arranging the inward convex reinforcement structure 102 and the convex structure 103 on the box wall of the box body 100, a concave-convex transition box wall is formed to enhance the overall structural strength of the box body, and the inward convex reinforcement structure 102 is provided at the corner position of the box body 100 to reinforce the corner position of the box body 100, so that the box body as a whole is not easily twisted and deformed.

[0031] like Figure 1 As shown, in some embodiments of the present invention, the inwardly convex reinforcement structure 102 extends upward from the lower portion of the box body 100 .

[0032] Specifically, the inwardly convex reinforcement structure 102 extends upward from the lower portion of the box body 100 to a position at or having a set distance from the upper end surface of the box body 100 .

[0033] In some embodiments of the present invention, the box body 100 may be a polygonal structure such as a square, a rectangle, a pentagon, or a hexagon.

[0034] In some embodiments of the present invention, the box body 100 is a pulp molded product.

[0035] In some embodiments of the present invention, at the same side wall of the box body 100 , the distance between the inner convex reinforcement structure 102 and the convex structure 103 is 2 to 15 times the wall thickness of the box body 100 to achieve a better reinforcement effect.

[0036] Specifically, the distance between the inward convex reinforcement structure 102 and the convex structure 103 refers to the depth of the depression or the height of the convexity in the normal direction of the side wall (such as the lateral direction of the box body 100), the spacing distance between the inner wall surface of the inward convex reinforcement structure 102 and the convex structure 103, or the spacing distance between the outer wall surfaces.

[0037] like Figure 1 、 Figure 2 As shown, in some embodiments of the present invention, an end surface portion 110 is provided at the opening edge position of the concave cavity 101, and an inner convex ridge 104 protruding toward the inner side of the box body 100 is provided at the junction of the inner convex reinforcement structure 102 and the end surface portion 110. The inner convex ridge 104 reinforces the inner wall and end face of the box body 100, further improving the structural strength of the box body 100.

[0038] Specifically, by setting the end surface portion 110 and strengthening the structural strength between the inner wall and the end surface of the box body 100 through the inner ridge 104, when the box body 100 is subjected to a torsional force, the force can be transmitted to the end surface portion 110, so that the end surface portion 110, the corner, the inner convex reinforcement structure 102, the convex structure 103, and the top of the box body 100 work together to enhance the structural strength of the box body 100 as a whole.

[0039] In some embodiments of the present invention, each inward convex reinforcement structure 102 is provided with at least two inward ridges 104, and at least one inward ridge 104 is located on the side of the corner, that is, at least one inward ridge 104 is located on one of the side walls of the corner of the box body 100 at the corner position, and the remaining inward ridges 104 can be provided at the corner position or the other side wall of the corresponding corner of the box body 100, so that the inward ridge 104 has a better reinforcement effect on the inner wall and end face of the box body 100.

[0040] It is understandable that in some embodiments of the present invention, the inner ridge 104 can be set at any position where the inner convex reinforcement structure 102 and the end surface portion 110 meet, and the structural strength between the inner wall and the end surface of the box body 100 can be enhanced.

[0041] In some embodiments of the present invention, each inward convex reinforcement structure 102 is configured with at least two inward ridges 104, and at least one inward ridge 104 is located at a corner, and at least one inward ridge 104 is located at the tip of the corner of the box body 100, so that the inward ridge 104 can have a certain reinforcement effect on the corner of the box body 100.

[0042] Specifically, such as Figure 1 As shown, each inner convex reinforcement structure 102 is configured to two inner convex ribs 104, wherein one inner convex rib 104 is located at the corner and the other inner convex rib 104 is located at the side of the corner, thereby reinforcing the corner and the inner wall and end surface of the box body 100 adjacent to the corner.

[0043] It is understandable that, in some embodiments of the present invention, each inwardly convex reinforcement structure 102 may be provided with three or more inwardly convex ribs 104 to achieve different reinforcement effects.

[0044] like Figure 1 As shown, in some embodiments of the present invention, the box body 100 has a rectangular structure, and at least one inner ridge 104 in each of the inner convex reinforcement structures 102 (at each corner position) is located on the short side of the box body 100 to strengthen the structural strength of the inner wall and end face of the short side of the box body 100.

[0045] It can be understood that in some embodiments of the present invention, the box body 100 can also be a polygonal structure such as a square, pentagon, or hexagon, and the inner ridge 104 can be set on a set side wall or each side wall as needed to achieve the effect of a reinforced structure at a set position.

[0046] like Figures 1 to 4 As shown, in some embodiments of the present invention, an end face portion 110 is provided at the opening edge of the concave cavity 101, and the end face portion 110 is a planar structure. An extension portion 120 is provided at the outer edge of the end face portion 110, and the extension portion 120 extends in the opposite direction of the opening of the concave cavity 101, so that the end face of the box body 100 has a concave-convex structure (the end face portion 110 bulges upward and the extension portion 120 extends downward), thereby enhancing the structural strength of the opening of the box body 100.

[0047] In some embodiments of the present invention, the end surface portion 110 is in an outwardly convex state and is substantially flat to facilitate operations such as lamination or heat sealing.

[0048] In some embodiments of the present invention, the end surface portion 110 at the corner position of the box body 100 is provided with a weakening line, which connects the two corner edges of the corner position, so that the end surface portion 110 located at the corner position can be broken or torn off along the weakening line, so as to facilitate tearing off the film material after the box body is coated.

[0049] After the box body is coated, when the box body needs to be opened, the end surface portion 110 at the corner position is broken through the weakening line, and the end surface portion 110 (the end surface portion 110 itself is connected to the film material) is pulled inward to tear off the film material, making it easier to open the box.

[0050] In some embodiments of the present invention, the junction between the convex structure 103 and the inner convex reinforcement structure 102 is a sloped structure, and the width of the convex structure 103 gradually increases from bottom to top to enhance the structural strength of the junction between the inner wall and the opening of the box body 100.

[0051] like Figure 3 As shown, in some embodiments of the present invention, the convex structure 103 is a trapezoidal structure that is larger at the top and smaller at the bottom, forming an arch-like structure, which has a good supporting effect on the side of the box body.

[0052] It can be understood that in some embodiments of the present invention, the convex structure 103 can also be set to a semicircular structure with a smaller bottom and a larger top, a triangular structure, etc.

[0053] In some embodiments of the present invention, the width of the convex structure 103 is 1 / 5 to 3 / 4 of the length of the side wall of the box body 100 where the convex structure 103 is located, that is, the convex structure 103 accounts for 1 / 5 to 3 / 4 of the side wall of the box body 100, and the inner convex reinforcement structure 102 accounts for 1 / 4 to 4 / 5 of the corresponding side wall, so as to achieve a more appropriate reinforcement effect.

[0054] Specifically, such as Figure 3 As shown, the side wall length of the box body 100 is D, the width of the convex structure 103 is d, d = (1 / 5) * D to (3 / 4) * D. It should be noted that the side wall length D of the box body 100 and the width d of the convex structure 103 should be understood as the width in the side view (such as Figure 3 ), the length or width at the same height position.

[0055] In some embodiments of the present invention, the width of the convex structure 103 is 1 / 3 to 1 / 2 of the length of the side wall of the box body 100 where the convex structure 103 is located. In this case, the box body has good structural strength.

[0056] like Figure 1 , Figure 2 As shown, the bottom portion of the box body 100 is provided with a groove portion 105 protruding toward the inner side of the box body 100 to enhance the structural strength of the bottom of the box body 100.

[0057] Specifically, the groove portion 105 can also be used to position the bottom of the box when the box is placed.

[0058] According to the box body stacking structure of the embodiment of the second aspect of the present invention, it includes at least two box bodies 100 of any embodiment of the above-mentioned first aspect of the present invention, and the inner ridges 104 of at least one corresponding inner convex reinforcement structure 102 of the two adjacent box bodies 100 are staggered with each other, so that when the two adjacent box bodies 100 are stacked, the corners of the staggered inner ridges 104 will not be completely close to each other, that is, the adjacent box bodies will not be completely close to each other, so that it is not easy to take out two or more box bodies at a time when taking out the boxes manually or mechanically, and it is convenient to take out and use the box bodies.

[0059] Specifically, one inner ridge 104 or more inner ridges 104 may be staggered at the corresponding inner ridge reinforcement structures 102 of two adjacent box bodies 100 to achieve a non-close-fitting stacking structure.

[0060] Of course, the invention of the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
