Description

Technical Field

[0001] This utility model relates to a box, belonging to the field of packaging box technology. Background Technology

[0002] Boxes are widely used packaging products. Depending on the materials used, they include corrugated cardboard boxes, single-layer cardboard boxes, etc., and come in various specifications and models. Boxes with specific dimensions can also be designed to fit the product being packaged. They are typically used as wrapping materials or protective outer layers for goods. Cardboard boxes are the most common type. The volume of a cardboard box varies depending on the size of the goods. After unfolding the box, its specific dimensions can be analyzed based on its shape, and its length, width, and height can be determined through precise measurements. When using cardboard boxes, they need to be folded into a three-dimensional shape before being used to package items such as fruits. Cardboard boxes generally include a base and multiple side panels, with flaps on the side panels. The base and side panels form a space to hold the items, and the flaps can be closed to achieve sealing. Because fruits and vegetables require stacking during refrigeration and transportation, the cardboard box material needs to meet moisture-proof and load-bearing requirements. To prevent cardboard boxes from being damaged by pressure after getting damp, it is often necessary to add moisture-proof processes and increase the amount of paper used, as well as increase the thickness of the side walls to improve moisture resistance or strength, such as with top and bottom cardboard boxes. This will increase the cost of cardboard boxes, waste paper materials, and is not conducive to environmental protection. Utility Model Content

[0003] The purpose of this invention is to provide a box with stronger load-bearing capacity to address the shortcomings of existing technologies.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A box includes a hollow box body in the shape of a cuboid. The box body includes a first side panel and a second side panel. The top of the first side panel is provided with an outer flap, and the top of the second side panel is provided with an inner flap. Adjacent first and second side panels are connected to form inner corners. At least two inner corners of the box body are provided with uprights. The bottom of the uprights abuts against the inner bottom surface of the box body, and the top of the uprights is flush with the top of the second side panel. The top of the uprights is lower than the top of the first side panel. The height difference between the top of the uprights and the top of the first side panel is 1-1.2 times the thickness of the inner flap.

[0006] Therefore, by setting up uprights, the load-bearing capacity of the container can be improved. Furthermore, the placement of the uprights at the top and bottom allows the inner and outer flaps to close sequentially, forming a relatively regular container structure. Moreover, vertical loads can be transferred from top to bottom through the outer and inner flaps and the uprights. Thus, when multiple containers are stacked, the load can be effectively transferred downwards through the uprights and the corresponding outer and inner flaps, increasing the container's load-bearing capacity and effectively reducing the load or weight borne by the container itself. This helps reduce the requirements for container materials and quantity, and also saves costs.

[0007] Furthermore, the number of columns is 3-4 to better ensure the strength improvement effect.

[0008] Furthermore, the number of uprights is four; a first connecting column is provided on the first side plate, and the two ends of the first connecting column are respectively connected to the uprights at both ends of the first side plate, and / or a second connecting column is provided on the second side plate, and the two ends of the second connecting column are respectively connected to the uprights at both ends of the second side plate, thereby forming a support frame and further improving the load-bearing capacity of the box.

[0009] Furthermore, the first side panel has two parallel connecting columns arranged vertically, with the top surface of the upper connecting column flush with the top of the upright column and the bottom surface of the lower connecting column flush with the bottom of the upright column. Similarly, the second side panel has two parallel connecting columns arranged vertically, with the top surface of the upper connecting column flush with the top of the upright column and the bottom surface of the lower connecting column flush with the bottom of the upright column. This creates a more stable support frame, further enhancing the load-bearing capacity of the box.

[0010] Furthermore, the connecting post is a square prism, and the material of the connecting post is one of wood, bamboo, or plywood. Optionally, the connecting post is bonded to the box body.

[0011] Furthermore, it also includes an inner bottom plate located at the bottom of the enclosure, with the bottom end of the uprights fixedly connected to the inner bottom plate. This not only further improves the load-bearing capacity but also facilitates manufacturing and use, as the uprights can be directly placed into the enclosure via the inner bottom plate, eliminating the need for bonding or other similar processes.

[0012] Furthermore, the inner bottom plate is made of one of the following materials: wood, bamboo, or plywood.

[0013] Furthermore, the column is a triangular prism or a quadrangular prism. Optionally, the column is bonded to the housing.

[0014] Furthermore, the material of the column is one of wood, bamboo, or plywood.

[0015] Wood and bamboo are both upstream raw materials for paper, and their cost is usually lower than that of paper; plywood is usually formed by extruding wood chips and adhesives, and its cost is also relatively low.

[0016] Furthermore, the box body is made of paper. This invention, through the internal reinforcement structure such as columns, can improve the overall load-bearing capacity of the box body, thereby saving paper usage and reducing the cost of the cardboard box.

[0017] Optionally, the box body is made of corrugated paper or single-layer cardboard.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This utility model can increase the vertical load-bearing capacity of the box by using internal reinforcing structures such as columns, which helps to reduce the amount of paper used in the cardboard box.

[0020] 2. This utility model reduces the load-bearing requirements of paper boxes and lowers the moisture-proof requirements of paper boxes in the refrigeration process, thereby reducing the cost of moisture-proof treatment for paper boxes.

[0021] 3. This utility model can select materials such as wood and bamboo as support components such as columns and connecting columns, and can be produced in areas with abundant raw materials, resulting in extremely low mass production costs.

[0022] 4. The supporting components such as the uprights and connecting columns of this utility model can be connected to the box body by adhesive bonding, which makes the finished product process relatively simple and the overall labor cost low. Attached Figure Description
