In order to improve the overall strength of the corrugated paper packaging box and improve the extrusion resistance of the corrugated paper packaging box, the corrugated paper packaging box is provided with a reinforcing structure 4, so that the corrugated paper packaging box can be suitable for fragile products such as household appliances and kitchen ware. The prior art improves the strength of corrugated paper packing cases by arranging combined outer packing cases and inner packing cases, arranging reinforcing frames on the surfaces of the packing cases and the like, and the structure and the arrangement mode of the reinforcing structures 4 can be the same as the prior art, so that the strength of the corrugated paper packing cases can be integrally improved on the side walls 13 of the case body, and the strength of the top cover 2 and the bottom cover 3 can be improved by arranging the corrugated paper packing cases on the top cover 2 and the bottom cover 3.

In some embodiments, the reinforcing structure 4 is a support bar disposed on the side wall 13 of the case in the vertical direction, and two ends of the support bar are respectively abutted against the top cover 2 and the bottom cover 3. The supporting rods can be arranged at positions of the side walls 13 of the box body, which are easy to be acted by external force in a clamping and bonding mode, for example, the supporting rods are arranged at four edges of the box body 1 in a quadrangular prism shape, and when the edges or the positions of the side walls 13 of the box body, which are close to the edges, are extruded in the horizontal direction, the external force can be transmitted to the supporting rods; when the top cover 2 and the bottom cover 3 are pressed in the vertical direction at the positions close to the edges, the external force can be transmitted to the support rods. The supporting rod provides supporting force for the corrugated paper packaging box to resist the extrusion effect, so that the strength of the corrugated paper packaging box is improved as a whole, and the corrugated paper packaging box can be suitable for packaging fragile products such as household appliances, kitchen tools and the like.

In this embodiment, the reinforcing structure 4 is a paper tube as shown in fig. 1 and 2.

The paper tube has higher structural strength than corrugated board, and can provide enough supporting force for resisting the extrusion action when the corrugated paper packaging box is extruded; in addition, the paper tube is light in weight and has a hollow structure, the quality of the corrugated paper packaging box cannot be obviously increased by arranging the paper tube, and the transportation cost can be reduced; the paper tube is made of paper material, the raw material costs of the paper tube are at the bottom, and the corrugated container manufacturing enterprises generally have the ability to self-prepare the paper tube, so that the paper tube has lower use costs than other types of reinforcing structures 4.

In order to facilitate the arrangement of the paper tubes on the box 1, a peripheral frame 15 may be arranged inside the four edges 14 of the box 1. The enclosing frame 15 and the box side wall 13 enclose to form a paper tube insertion hole extending along the vertical direction, so that a paper tube is inserted into the insertion hole formed by the enclosing frame 15 and the box side wall 13.

In this embodiment, the enclosure frame 15 and the case body 1 are integrally formed, so as to simplify the structure of the corrugated paper packaging case and improve the assembly efficiency, thereby reducing the use cost of the corrugated paper packaging case. Specifically, three equal-height inward creasing lines may be provided on the side wall 13 of the case, and the top and bottom of the three inward creasing lines are cut along the length direction of the corrugated board, so as to fold the inward creasing lines to form the enclosure frame 15.

The inside of the box body 1 is provided with a baffle plate 5, and the structure of the baffle plate 5 is shown in fig. 4 and 5.

The outer edge of the top plate 51 abuts against the case side wall 13. For example, four right angles of the top plate 51 are cut into four rectangular notches matched with the cross section shape of the surrounding frame 15, the partition plate 5 can conveniently enter the box 1 from the top opening 11 or the bottom opening 12 of the box 1, the laying process of the partition plate 5 is not blocked by the surrounding frame 15 protruding towards the inner side of the box side wall 13, the laid top plate 51 is horizontally arranged, the top plate 51 is abutted against the box side wall 13 and is perpendicular to the box side wall 13, therefore, the top plate 51 is equivalent to a reinforcing platform arranged in the box side wall 13, when the box side wall 13 is extruded, the top plate 51 is elastically deformed under the extrusion action, a certain supporting force is provided through rebound of the top plate 51, and the extrusion resistance of the corrugated paper packaging box is improved.

When the partition 5 is only formed by the top plate 51, the contact part between the partition 5 and the box side wall 13 is the outer edge of the top plate 51, the contact mode between the partition 5 and the box side wall 13 is line contact, the smaller contact area leads to poor structural relevance between the partition 5 and other parts of the corrugated paper packaging box, the position of the partition 5 is easy to change when the box 1 is extruded, so that the top plate 51 and the box side wall 13 lose the mutually perpendicular relation, and the top plate 51 cannot play a role in resisting extrusion.

For this reason, in this embodiment, the partition 5 further includes first flaps 52 formed by extending from the outer edge of the top plate 51 down along the case side wall 13 to adjacent supporting surfaces including the bottom plate of the bottom cover 3 and the adjacent top plate 51, and the number of the first flaps 52 is not less than two and is symmetrically disposed two by two, and the first flaps 52 are attached to the case side wall 13. For example, the first folding plate 52 is formed by extending downward from the front side outer edge and the rear side outer edge of the top plate 51; or the first folding plate 52 is formed by extending downward the left and right outer edges of the top plate 51; or the first folding plate 52 is formed by extending downward the front side outer edge, the rear side outer edge, the left side outer edge, and the right side outer edge of the top plate 51. The bottom of the first folding plate 52 is in line contact with the adjacent supporting surface, and the first folding plate 52 forms a 'support leg' for erecting the top plate 51 above the bottom cover 3 or the adjacent top plate 51, so that the partition plate 5 can be stably arranged on the adjacent supporting surface; besides the line contact with the adjacent supporting surface, the first folding plate 52 is attached to the side wall 13 of the box body, the contact part of the partition plate 5 and the side wall 13 of the box body comprises the outer edge of the top plate 51 and the side wall of the first folding plate 52, the contact mode between the partition plate 5 and the side wall 13 of the box body is changed from the line contact to the surface contact, the contact area between the partition plate 5 and the side wall 13 of the box body and the adjacent supporting surface is increased, and the structural association is enhanced, so that the position of the partition plate 5 is not easy to change, the top plate 51 can be well kept at the position vertical to the side wall 13 of the box body, and a certain supporting force is provided, so that the top plate 51 plays a role in resisting extrusion.

Further, the partition 5 further includes a second folded plate 53, where the second folded plate 53 is formed by extending the bottom of the first folded plate 52 along the adjacent supporting surface toward the inner side of the case 1, and the second folded plate 53 is attached to the adjacent supporting surface, and the adjacent supporting surface includes the bottom plate of the base 3 and the adjacent top plate 51. Because the second folding plate 53 is attached to the bottom wall of the bottom cover 3 or the adjacent top plate 51, the second folding plate 53 and the first folding plate 52 form an L-shaped "leg step" arranged on the adjacent support, and the contact mode between the partition plate 5 and the adjacent support surface is changed from line contact to surface contact, so that the surface contact exists between the partition plate 5 and the side wall 13 of the box body and between the partition plate 5 and the adjacent support surface, the contact area between the partition plate 5 and the side wall 13 of the box body and the adjacent support surface is increased, and the structural association is further enhanced, so that the position of the partition plate 5 is more difficult to change, the top plate 51 can be better kept at the position vertical to the side wall 13 of the box body and provides a certain supporting force, and the top plate 51 plays a role in resisting extrusion. In addition, through setting up the second folded plate 53, the position of baffle 5 is difficult to change more, consequently first folded plate 52 can be good laminating on box lateral wall 13 to make the better transmission of the extrusion effort that box lateral wall 13 received to first folded plate 52 surface, first folded plate 52 is equivalent to the additional inner packing layer that sets up in box 1 this moment, provides certain holding power through the resilience force that first folded plate 52 self intensity and elastic deformation produced, further improves the ability of corrugated container resistance to extrusion.
