Description

Technical Field

[0001] This utility model relates to the field of paper packaging boxes, and in particular to a paper packaging box with a reinforced structure. Background Technology

[0002] Paper packaging boxes are a widely used type of packaging container, primarily made of cardboard or paper, offering excellent protection, storage, and transportation capabilities. Paper packaging boxes offer significant advantages such as low cost, lightweight construction, and ease of storage and transport. Furthermore, they can be customized to meet the specific packaging requirements of different products.

[0003] In practical applications, the corners of a cardboard box are key support points for its overall structure. Once a corner is damaged, the overall stability of the cardboard box will be severely affected. Damaged corners mean that when the cardboard box is subjected to external forces, it cannot effectively distribute and resist pressure as it would in a healthy state, making it more prone to deformation and breakage.

[0004] Damaged corners can also weaken the stacking strength of cartons. Cartons are typically stacked during storage and transportation. If the corners are damaged, the cartons are prone to tilting or collapsing when stacked, which not only reduces stacking stability but can also damage other cartons and the contents inside.

[0005] Furthermore, damaged corners reduce the protective performance of the cardboard box for the goods. The main function of a cardboard box is to protect the goods inside from damage, and the corners are the most vulnerable parts of the box. Once damaged, the box is more likely to break when subjected to external impact, thus losing its protective function. Utility Model Content

[0006] The main objective of this invention is to provide a paper packaging box with a reinforced structure, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A paper packaging box with a reinforced structure includes an outer box, an inner box, and a box compartment, wherein the inner box is located inside the outer box, and the inner cavity of the inner box is the box compartment;

[0009] A cavity is formed between the inner box and the outer box, and a reinforcing honeycomb plate is inserted into the cavity. The upper end of the reinforcing honeycomb plate is provided with a top reinforcing ring, and the top reinforcing ring is fixedly connected to the inner box and the outer box. The reinforcing honeycomb plate is fixedly connected to the inner box and the outer box.

[0010] A corner reinforcement is installed at the inner corner of the box, and the corner reinforcement includes a top connecting block and an arc-shaped reinforcing strip. The top connecting block is installed at the inner corner of the top reinforcing ring, and an arc-shaped reinforcing strip is installed on the top connecting block. The arc-shaped reinforcing strip has multiple protruding rings inside, and the two ends of the protruding rings are provided with buckles, which are used to fix it to the inner box body to achieve reinforcement at the corner of the paper packaging box.

[0011] As an optional solution of this application, the end face of the reinforced honeycomb plate is provided with a plurality of honeycomb holes, and the plurality of honeycomb holes are equidistantly distributed on the reinforced honeycomb plate. The honeycomb holes are divided into inner holes and outer holes, and the inner holes and outer holes are designed in an alternating manner.

[0012] As an optional solution of this application, the top connecting block and the top reinforcing ring are designed as an integral part, and the connection between the top connecting block and the top reinforcing ring is designed as a fold. The corner of the top connecting block is designed as an arc, and the top connecting block is fan-shaped when viewed from above.

[0013] As an optional solution of this application, the arc-shaped reinforcing strip is integrated with the top connecting block, and the cross-section of the arc-shaped reinforcing strip is arc-shaped. The arc-shaped reinforcing strip and the top connecting block are perpendicular to each other, and the lower end of the arc-shaped reinforcing strip abuts against the bottom of the container.

[0014] As an optional solution of this application, the inner hole of the protruding ring is provided with a plurality of reinforcing curved strips, the plurality of reinforcing curved strips are equidistantly distributed, the reinforcing curved strips are embedded in the inner hole of the protruding ring, and the buckle and the protruding ring are designed as an integral unit;

[0015] As an optional solution of this application, multiple protruding rings are equidistantly distributed on the arc-shaped reinforcing strip, the protruding rings and the arc-shaped reinforcing strip are designed as a single unit, and the buckles are distributed on both sides of the protruding rings and are adapted to the inner box buckle.

[0016] As an optional solution in this application, a cavity is formed between the arc-shaped reinforcing strip and the inner box, and the cavity is separated by a protruding ring to form an isolation cavity, thereby improving the compressive strength of the arc-shaped reinforcing strip.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The multiple honeycomb holes created in the honeycomb panel significantly enhance the overall strength and stability of the paper packaging box. The staggered arrangement of the honeycomb holes optimizes the structural stress, allowing the packaging box to distribute pressure more evenly when subjected to external forces, thereby improving its resistance to compression and deformation.

[0019] The introduction of corner reinforcement, an integrated design of its top connecting block and curved reinforcing strip, provides extra support and reinforcement for the corners of the packaging box. This design not only enhances the structural strength of the corners but also improves the overall durability and impact resistance of the packaging box.

[0020] A robust reinforced structural system is formed by the fixed connection between the top reinforcing ring and the honeycomb panel, as well as the inner and outer boxes. This system not only enhances the overall rigidity of the packaging box but also improves its resistance to tearing and damage.

[0021] The protruding rings and reinforced curved strips in the corner reinforcements further enhance the packaging box's compressive strength and structural stability. These designs, by creating multiple isolated small cavities through partitioning the interior, effectively absorb external impacts and reduce deformation and damage to the packaging box during stress.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 - Figure 5 As shown, a reinforced paper packaging box includes an outer box 1, an inner box 2, and a compartment 3. The inner box 2 is designed to be embedded in the internal space of the outer box 1, and its inner cavity constitutes the compartment 3.

[0030] A cavity structure is formed between the inner housing 2 and the outer housing 1, and a reinforcing honeycomb panel is embedded in this cavity. The upper part of the honeycomb panel is designed with a top reinforcing ring 4, which is fixedly connected to the inner housing 2 and the outer housing 1. At the same time, the honeycomb panel itself is also fixedly connected to the inner housing 2 and the outer housing 1.

[0031] A corner reinforcement 7 is installed at the inner corner of the box compartment 3. The corner reinforcement 7 consists of a top connecting block 71 and an arc-shaped reinforcing strip 72. The top connecting block 71 is installed at the inner corner of the top reinforcing ring 4, and the arc-shaped reinforcing strip 72 is fixed on the top connecting block 71. The arc-shaped reinforcing strip 72 has multiple protruding rings 74 inside, and the two ends of these protruding rings 74 are provided with buckles 76. The arc-shaped reinforcing strip 72 is fixed to the inner box body 2 by the buckles 76, thereby achieving the reinforcement effect at the corner of the paper packaging box.

[0032] Multiple honeycomb holes 6 are formed on the end face of the honeycomb panel, and these honeycomb holes 6 are equidistantly distributed on the honeycomb panel. The honeycomb holes 6 are designed as inner holes and outer holes, which are arranged alternately to achieve the best reinforcement effect.

[0033] The top connecting block 71 and the top reinforcing ring 4 are designed as a single unit, with a folded design at the connection point. The corners of the top connecting block 71 are arc-shaped, while its top view is fan-shaped.

[0034] The curved reinforcing strip 72 and the top connecting block 71 are integrated into one piece. The cross-section of the curved reinforcing strip 72 is curved and perpendicular to the top connecting block 71. The lower end of the curved reinforcing strip 72 abuts against the bottom of the compartment 3 to provide additional support and reinforcement.

[0035] Multiple reinforcing curved strips 75 are designed into the inner hole of the protruding ring 74. These reinforcing curved strips 75 are evenly distributed and embedded in the inner hole of the protruding ring 74. The buckle 76 and the protruding ring 74 adopt an integrated design to ensure the stability of the structure.

[0036] Multiple protruding rings 74 are equidistantly distributed on the arc-shaped reinforcing strip 72 and are integrated with the arc-shaped reinforcing strip 72. Clips 76 are distributed on both sides of the protruding rings 74 and are adapted to the latches of the inner housing 2 to ensure the stability and reliability of the reinforced structure.

[0037] A cavity 73 is formed between the arc-shaped reinforcing strip 72 and the inner box 2. The cavity 73 is separated by a protruding ring 74, forming multiple isolated small cavities. This not only improves the compressive strength of the arc-shaped reinforcing strip 72, but also enhances the structural stability of the entire packaging box.

[0038] The inner housing 2 is installed inside the outer housing 1, ensuring that the inner cavity forms the compartment 3. A certain space is reserved between the inner housing 2 and the outer housing 1 to form a clamping cavity. A reinforcing honeycomb panel is inserted into the clamping cavity. The top reinforcing ring 4 is connected to the inner housing 2 and the outer housing 1 by a fixed connection. At the same time, the reinforcing honeycomb panel 5 is also connected to the inner housing 2 and the outer housing 1 by a fixed connection.

The top connecting block 71 is installed at the inner corner of the top reinforcing ring 4, and the arc-shaped reinforcing strip 72 is installed on the top connecting block 71. The arc-shaped reinforcing strip 72 is fixed to the inner housing 2 by a snap-fit ​​76 to ensure the corner reinforcement effect. Ensure that multiple honeycomb holes 6 are opened on the end face of the reinforcing honeycomb panel 5, and that they are arranged in an alternating manner to achieve the best reinforcement effect.

[0039] The top connecting block 71 and the top reinforcing ring 4 are integrated into one piece, with a folded design at the connection point and an arc-shaped corner, giving it a fan-shaped appearance when viewed from above. The arc-shaped reinforcing strip 72 is also integrated into the top connecting block 71, with an arc-shaped cross-section, its lower end abutting against the bottom of the compartment 3. Multiple protruding rings 74 are evenly distributed on the arc-shaped reinforcing strip 72, also integrated into one piece. Multiple reinforcing curved strips 75 are designed into the inner holes of the protruding rings 74 and embedded therein. The buckles 76 are integrated into the protruding rings 74, distributed on both sides of the protruding rings 74, and adapted to the snap-fit ​​of the inner box 2. A cavity 73 is formed between the arc-shaped reinforcing strip 72 and the inner box 2. The protruding rings 74 divide the cavity 73, forming multiple isolated small cavities, thereby improving compressive strength and structural stability.
