Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cartons, and particularly relates to a high-strength seven-layer corrugated carton. Background Technique

[0002] With the rapid development of the logistics industry, the requirements for packaging cartons are also getting higher and higher. During the transportation and storage of goods, packaging cartons need to withstand various external forces, such as stacking pressure, impact, vibration, etc.

[0003] Traditional corrugated cartons often stack corrugations in a single direction. When bearing vertical pressure, only the corrugations in this direction play a major role in compression resistance, and they are prone to deformation due to local stress concentration. The overall compression strength is much lower than that of cartons with staggered stacking. In the face of impacts from different directions, due to the single corrugation orientation, only limited buffering can be provided in a specific direction, and the ability to resist impacts from other directions is insufficient.

[0004] There are problems such as insufficient compression resistance, poor impact resistance, and poor stability, which are likely to cause damage to the internal items during transportation, increasing logistics costs and resource waste.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

[0008] Furthermore, the box body also includes inflation rods, there are multiple inflation rods, and the inflation rods are distributed in each corner of the paper surface and the first corrugated board.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0022] A high-strength seven-layer corrugated cardboard box, including a box body 1, the box body 1 is composed of a bottom plate and side plates rotatably connected to the bottom plate, the side plates are adhesively connected to each other, and the side plates or the bottom plate both include a paper surface 101, including an inner and outer paper surface; a first corrugated board 102, on which the crests or troughs are distributed horizontally; a second corrugated board 103, on which the crests or troughs are distributed longitudinally; the side plates or the bottom plate are adhesively connected in sequence by an outer paper surface, the first or second corrugated board, and an inner paper surface. There are three first corrugated boards 102 arranged at intervals between the paper surfaces 101, and there are two second corrugated boards 103, and the two second corrugated boards 103 are distributed in the intervals between the first corrugated boards 102.

[0023] The side plates or the bottom plate are composed of two layers of paper surface 101, the first corrugated board 102 and the second corrugated board 103. When the box body 1 is longitudinally impacted, the second corrugated board 103 absorbs the impact energy through its own compressive deformation to play a buffering role. Similarly, when laterally impacted, the first corrugated board 102 plays a buffering function.

[0024] The material of the paper surface 101 is kraft paper. The material of the kraft paper ensures the waterproofness and durability of the box body 1, enables the box body 1 to have excellent waterproof performance, can be applied to humid environments, and also improves its service life.

[0025] The staggered arrangement of the first corrugated board 102 and the second corrugated board 103 enables the corrugations in all directions to jointly bear the pressure when subjected to pressures in different directions, dispersing the stress to the entire box body 1 structure, thereby improving the compressive resistance of the box body 1 and maintaining the shape and size stability of the box body 1.

[0026] By adopting the above design, the compressive resistance and impact resistance of the box body 1 are significantly improved, which can provide reliable protection for the internal items and reduce the damage risk of the items during transportation and storage.

[0027] The rigidity of the box body 1 is increased, making the box body 1 have good stability in all directions. Whether during stacking or handling, it can maintain its shape and size and will not easily deform, improving the reliability of packaging.

[0028] Furthermore, the box body 1 further includes a plurality of inflatable rods 104, and the inflatable rods 104 are distributed in each corner of the paper surface 101 and the first corrugated board 102.

[0029] The inflatable rods 104 are distributed in each corner of the paper surface 101, the first corrugated board 102 and the second corrugated board 103. When the box body 1 is subjected to an external force, the inflatable rods 104 can further provide buffering, and since the gas has a certain elasticity, it can better absorb and disperse the impact force, reducing the impact on the internal items of the box body 1.

[0030] By adopting the above design, the compressive resistance and impact resistance of the box body 1 are further improved, which can provide more reliable protection for the internal items and further reduce the damage risk of the items during transportation and storage.

[0031] Furthermore, anti-collision corners 3 are provided on the box body 1. There are eight anti-collision corners 3, which are respectively installed at the eight corners of the box body 1. The anti-collision corners 3 are divided into two groups, one group is on the top surface and the other group is on the bottom surface. A reinforcing rib 301 is arranged between each group of anti-collision corners 3.

[0032] The anti-collision corners 3 are installed at the eight corners of the box body 1, so that when the corners of the box body 1 are impacted, the anti-collision corners 3 bear the impact first, protecting the main structure of the box body 1.

[0033] The reinforcing rib 301 is arranged between the anti-collision corners 3 on the top surface and the bottom surface, forming a stable frame structure and enhancing the overall impact resistance of the box body 1.

[0034] The setting of the anti-collision corners 3 and the reinforcing rib 301 not only improves the strength of the box body 1, but also facilitates handling to a certain extent, avoiding the influence on the handling operation due to damage to the corners.

[0035] Furthermore, a top cover 2 is rotatably connected to the top surface of the box body 1. An adhesive member 4 is provided on the front surfaces of the box body 1 and the top cover 2. The adhesive member 4 includes a plush layer installed on the box body 1 and a burr layer installed on the top cover 2.

[0036] The rotatable connection of the top cover 2 and the design of the adhesive member 4 make the opening and closing of the carton very convenient. At the same time, this sealing connection method can effectively protect the internal items and prevent the influence of external factors.

[0037] Working principle:

[0038] When the box body 1 is longitudinally impacted, the second corrugated board 103 absorbs the impact energy through its own compressive deformation to play a buffering role. Similarly, when it is transversely impacted, the first corrugated board 102 plays a buffering function.

[0039] The staggered arrangement of the first corrugated board 102 and the second corrugated board 103 enables the corrugations in all directions to jointly bear the pressure when subjected to pressures in different directions, dispersing the stress to the entire structure of the box body 1, thereby improving the compressive resistance of the box body 1 and maintaining the shape and size stability of the box body 1.

[0040] The inflatable rods 104 are distributed in each corner of the paper surface 101, the first corrugated board 102 and the second corrugated board 103. When the box body 1 is subjected to an external force, the inflatable rods 104 can further provide buffering, and since the gas has a certain elasticity, it can better absorb and disperse the impact force, further reducing the impact on the internal items of the box body 1.
