Therefore, it is necessary to use cartons with better compression resistance and anti-deformation to meet the use requirements.

[0003] In the prior art, there is a reinforced pressure-proof carton disclosed in publication number CN115180265A, which includes a carton main body, and reinforcement components are fixedly assembled on the upper and lower inner walls of the carton main body.

[0036] Furthermore, the outer edge of the edge groove 11 is set as the edge groove docking bevel 12, the outer edge of the edge strip 21 is set as the edge strip docking bevel 22, and the edge groove docking bevel 12 and the edge strip docking bevel 22 are docked together, which can increase the contact area when the edge strip 21 and the edge groove 11 are docked, thereby improving the connection strength at the docking point, and before the edge strip 21 and the edge groove 11 are docked, there is a certain gap between the two docking bevels, so even if there is a slight inward concave deformation at the opening upper end of the box body 1, the edge strip 21 can be smoothly clamped in the edge groove 11, and the deformed part can be corrected so that the box body 1 can restore its initial undeformed shape.

[0037] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the corner reinforcement plate 3 is glued to the intersection of the side and bottom of the box body 1, and the corner reinforcement plate 3 includes a corner pulp layer 31 and a corner stretch paper rope 32.

Its own strength is greater than the strength of the pulp, so the corner stretch paper rope 32 plays a role of internal reinforcement similar to that of steel bars, and the corner pulp layer 31 is similar to the shaping and pouring of concrete to form an integral structure, which can make the corner reinforcement plate 3 have better structural strength and compression and deformation resistance. Therefore, the corner reinforcement plate 3 plays a further protective role on the intersection of the side and bottom edges of the box body 1, which can prevent the bending part from being worn and enhance the compression and deformation resistance of the bending part.

[0038] Furthermore, a plurality of edge reinforcement strips 8 are provided, and the edge reinforcement strips 8 are glued at the intersection and bend of adjacent sides. The edge reinforcement strips 8 include an edge pulp layer 81 and an edge stretching paper rope 82. The edge pulp layer 81 has two sides arranged perpendicular to each other.

The edge stretching paper rope 82 is a rope twisted into a strip shape. The corner reinforcement strip 8 has a good structural strength and anti-compression and anti-deformation properties. Therefore, the corner reinforcement strip 8 plays a further protective role on the intersection and bend of adjacent sides of the box body 1, which can prevent the bend from being directly impacted and enhance the anti-compression and anti-deformation capabilities of the bend.

[0039] like Figure 8 , Fig. 9 and Fig.10As shown, the cardboard core board 5 includes a core board pulp layer 51 and a core board stretched paper rope net 52.

The core board stretched paper rope net 52 is similar to a steel cage and plays an internal reinforcement role. The core board pulp layer 51 is similar to the shaped casting of concrete to form an integral structure, which can make the cardboard core board 5 have better structural strength performance. Therefore, the cardboard core board 5 plays a structural support for the anti-pressure cardboard assembly, ensuring that the box body 1 and the box cover 2 prepared by the anti-pressure cardboard assembly are not easily torn and deformed.

[0040] Furthermore, the reinforcing rib plate 6 includes a folding support cardboard 61 and paper rope threading ribs 62. The folding support cardboard 61 is in a continuous folded shape. The paper rope threading ribs 62 penetrate through the folding surfaces of the folding support cardboard 61. A plurality of paper rope threading ribs 62 are provided, and the paper rope threading ribs 62 are glued together with the penetration parts of the folding support cardboard 61, so that the folding support cardboard 61 can form a better structural support between the outer cardboard layer 4 and the cardboard core board 5, and the provided paper rope threading ribs 62 can combine the folding surfaces of the folding support cardboard 61 together to further improve the compressive resistance.

[0041] Furthermore, a long strip of plane is arranged between any two folding surfaces of the folding support paperboard 61, and the long strip of plane is glued and fixedly connected to the outer paperboard layer 4 and the paperboard core board 5 on both sides, which can increase the contact area of ​​the connection part, thereby improving the firmness of the connection between the reinforcing rib plate 6, the outer paperboard layer 4 and the paperboard core board 5.

[0042] Working principle: The box body 1 and the box cover 2 composed of a pressure-resistant cardboard component are used to make the carton have good pressure resistance and anti-deformation performance. The outer cardboard layer 4 of the pressure-resistant cardboard component makes the pressure-resistant cardboard component have a flat outer wall, so that the outer walls of the box body 1 and the box cover 2 prepared by the pressure-resistant cardboard component can be smooth and flat, and the cardboard core board 5 can enhance the structural strength of the pressure-resistant cardboard component and is not easy to tear. The reinforcing rib plate 6 can enhance the anti-deformation performance of the pressure-resistant cardboard component, so that the prepared box body 1 and the box cover 2 have good pressure resistance and anti-deformation performance, and corner reinforcement plates 3 and edge reinforcement strips 8 are added to strengthen the structure of the bending parts of the box body 1, which can further improve the pressure resistance and anti-deformation performance of the box body 1.
