Description

Technical Field

[0001] This application relates to the technical field of packaging supplies, and particularly relates to a high-strength combined paper box. Background Art

[0002] Paper boxes are a common form of packaging, widely used in multiple industries such as food, beverages, cosmetics, and electronic products. They are made of cardboard or corrugated cardboard and have the advantages of being lightweight, foldable, easy to print, and environmentally friendly. The design and structure of paper boxes can be customized according to specific needs to meet the packaging requirements of different products.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization announcement number CN205087239U, which discloses a paper box including a first side plate, a second side plate, a third side plate, and a fourth side plate connected in sequence, and further including a first side plate bottom tongue, a second side plate bottom tongue, a third side plate bottom tongue, and a fourth side plate bottom tongue. The first side plate bottom tongue and the first side plate, the second side plate bottom tongue and the second side plate, the third side plate bottom tongue and the third side plate, and the fourth side plate bottom tongue and the fourth side plate can all be rotatably connected, and the second side plate bottom tongue and the fourth side plate bottom tongue are mirror-symmetrically arranged on both sides of the third side plate bottom tongue.

[0004] However, since the above-mentioned paper box is folded from a single board, the structural strength of the paper box is relatively low, and it is easily deformed when jolted or squeezed by other items during transportation, resulting in poor protection ability for the items inside the paper box. Utility Model Content

[0005] In order to improve the strength of the paper box, this application provides a high-strength combined paper box.

[0006] The high-strength combined paper box provided by this application adopts the following technical solutions:

[0007] A high-strength combined paper box includes an outer box and an inner box. The outer box includes a bottom plate and four side plates arranged on the bottom plate. The side plates are provided with top plates. The four side plates can be folded into a vertical state and adhered to each other, and the top plates on the four side plates can be folded into a horizontal state to block the upper opening of the outer box. The inner box is located inside the outer box, the upper opening of the inner box is in an open state, items are placed in the inner box, a buffer space is left between the inner box and the outer box, a connection mechanism is provided on the outer box, and the inner box is connected to the outer box through the connection mechanism.

[0008] By adopting the above technical solution, the paper box is set as an outer box and an inner box. The outer box is folded to form a bottom plate, side plates and a top plate, thereby wrapping the inner box. Then, the inner box is fixed inside the outer box through a connecting mechanism, and a buffer space is provided to separate the outer box and the inner box. When the paper box is impacted by an external force during storage and transportation, the outer box will be deformed first under the force, the buffer space buffers the deformation amount of the outer box, and the inner box then absorbs the remaining acting force, thus effectively protecting the items placed inside the inner box and improving the overall structural strength of the paper box.

[0009] Optionally, the connecting mechanism includes:

[0010] A connecting hook, which is arranged on the outer side wall of the inner box;

[0011] A connecting rope, which is arranged on the bottom plate;

[0012] A connecting ring, which is arranged on the connecting rope and hung on the connecting hook;

[0013] A filling component, which is arranged in the buffer space, and the connecting rope is tightened under the action of the filling component.

[0014] By adopting the above technical solution, move the connecting rope to make the connecting ring hang on the connecting hook, and then fill the buffer space with the filling component to tighten the connecting rope, thus completing the position fixing work of the inner box inside the outer box. While the connecting rope limits the position of the inner box to a certain extent, it also enables the inner box to move and avoid to a certain extent when subjected to an external force, thereby better protecting the items inside the inner box from being damaged by the external force.

[0015] Optionally, the filling component includes:

[0016] Filling sponge, which is laid on the bottom plate and abuts against the bottom of the inner box;

[0017] Filling air cushion, which is laid on the side plate and abuts against the outer side wall of the inner box.

[0018] By adopting the above technical solution, filling sponge is laid at the bottom of the inner box. While the filling sponge buffers the impact force received by the bottom plate of the outer box, when the outer box is placed on a damp ground, the filling sponge can also absorb the moisture entering the bottom of the outer box, ensuring the dryness of the items inside the inner box; the filling air cushion fills the periphery of the inner box, fills the buffer space in the horizontal direction between the outer box and the inner box, and can effectively buffer the deformation amount of the outer box.

[0019] Optionally, a pressure - resistant plate is placed between the upper surface of the inner box and the top plate. The pressure - resistant plate includes a base plate and a number of rib plates arranged on the base plate. The base plate is placed on the inner box and the filling air cushion, and the rib plates are arranged on the base plate in a vertical state, with the tops of the rib plates abutting against the top plate.

[0020] By adopting the above - mentioned technical solution, a pressure - resistant plate is placed between the inner box and the top plate. The pressure - resistant plate supports the gap between the inner box and the top plate through the structure of the base plate and the rib plates, thereby improving the compressive strength of the top plate, enabling the force when the top plate is pressed to be dispersed on the base plate, and thus reducing the pressure on the inner box.

[0021] Optionally, a number of the rib plates are arranged in a honeycomb pattern on the base plate.

[0022] By adopting the above - mentioned technical solution, arranging a number of rib plates in a honeycomb pattern on the base plate improves the structural strength of the rib plates for supporting the top plate.

[0023] Optionally, mounting posts are provided at the four corners of the bottom plate. Vertical corner posts are inserted into the mounting posts. The outer side walls of the corner posts abut against two adjacent side plates, and the tops of the corner posts abut against the top plate.

[0024] By adopting the above - mentioned technical solution, mounting posts are fixedly installed at the four corners of the bottom plate, and then corner posts are inserted into the mounting posts. This enables the side plates and the top plate to be folded along the side walls and the top of the corner posts, making the folding work more convenient. Moreover, the corner posts also support the four corners of the outer box, improving the structural strength of the outer box.

[0025] Optionally, an arc - shaped guiding surface is provided at the top of the mounting post.

[0026] By adopting the above - mentioned technical solution, an arc - shaped guiding surface is provided at the top of the mounting post. When the corner post is inserted into the mounting post, the guiding surface can guide the corner post, facilitating the insertion and matching of the corner post and the mounting post, and improving the assembly efficiency.

[0027] Optionally, two through - holes horizontally penetrating the side plate are provided on the outer side wall of the side plate.

[0028] By adopting the above - mentioned technical solution, two through - holes are provided on the outer side wall of the side plate, enabling the staff to directly carry the outer box through the two through - holes or thread a rope through the two through - holes for lifting, improving the convenience of carrying the outer box.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. By setting the paper box into an outer box and an inner box, the outer box is folded to form a bottom plate, side plates and a top plate, thereby wrapping the inner box. Then, the inner box is fixed inside the outer box through a connecting mechanism, and a buffer space is provided to separate the outer box and the inner box. When the paper box is impacted by an external force during storage and transportation, the outer box will be deformed first, the buffer space buffers the deformation amount of the outer box, and the inner box absorbs the remaining acting force, thus effectively protecting the items placed inside the inner box and improving the overall structural strength of the paper box;

[0031] 2. By padding a sponge at the bottom of the inner box, while the sponge buffers the impact force on the bottom plate of the outer box, when the outer box is placed on a damp ground, the sponge can also absorb the moisture entering the bottom of the outer box, ensuring the dryness of the items inside the inner box; the filling air cushions are filled on the periphery of the inner box, filling the buffer space in the horizontal direction between the outer box and the inner box, and can effectively buffer the deformation amount of the outer box;

[0032] 3. By opening two through holes on the outer side wall of the side plate, the staff can directly carry the outer box through the two through holes or thread a rope through the two through holes for lifting, improving the convenience of carrying the outer box.
