Description

Technical Field

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

[0002] Cardboard boxes are commonly used packaging containers during the transportation, storage, and sale of goods. Traditional cardboard boxes are mostly straight-walled structures, which usually require additional support structures or specific stacking methods when stacked. Otherwise, they are prone to tipping over or collapsing, occupy a lot of space, and are inconvenient to stack.

[0003] At the same time, traditional cardboard boxes have limited structural strength and are prone to deformation when loaded with heavy items or subjected to external pressure, which affects the protection of the contents.

[0004] Therefore, this utility model provides a portable packaging cardboard box to solve the above problems. Utility Model Content

[0007] Preferably, the reinforcing component includes a top frame and a bottom frame, with side frames fixedly installed between the corresponding four corners of the bottom frame and the bottom frame. The bottom frame fits into the four bottom sides of the box body, and the top frame is flush with the four top sides of the box body.

[0008] Preferably, the side frame is fitted to the four corners of the box body side wall.

[0009] Preferably, the bottom frame has slots on both the front and rear sides, and a partition is inserted between the corresponding slots.

[0010] Preferably, the angle between the side wall of the box and the vertical direction is 5°-10°, and the slope of the four side walls of the box is consistent.

[0011] Preferably, the box body is made of corrugated cardboard, the reinforcing components are made of rigid plastic, and the reinforcing components are glued and fixed to the inner wall of the box body with environmentally friendly adhesive.

[0012] Beneficial effects

[0013] This utility model provides a portable packaging cardboard box. Compared with the prior art, it has the following advantages:

[0014] 1. This portable packaging box, with its square ladder design and 5°-10° side wall angle, allows multiple boxes to be nested and stacked by interlocking. Storage and organization can be completed without additional tools, greatly saving storage and transportation space, and the stacking process is simple and efficient.

[0015] 2. This portable packaging box features a reinforced top frame, bottom frame, and side frame that form a stable support structure, enhancing the box's resistance to deformation and better protecting the contents. The slots in the bottom frame, combined with the partitions, allow for flexible division of the internal space to meet the needs of different item classification and storage.

[0022] It should be noted that in the description of the embodiments of this application, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides a portable packaging cardboard box, including a box body 1. The box body 1 is made of corrugated cardboard, which has good cushioning and pressure resistance, and can play a certain role in protecting the internal items. It is also low in cost and easy to recycle. The box body 1 is provided with a reinforcing component 2, which is made of rigid plastic and has high structural strength. The reinforcing component 2 is fixed to the inner wall of the box body 1 with environmentally friendly adhesive, which is firmly connected. At the same time, the environmentally friendly adhesive is more environmentally friendly and will not cause harm to the environment.

[0025] The bottom surface of box 1 is smaller than the top surface. Box 1 is a square trapezoid with a larger top and a smaller bottom. The upper box 1 is inserted into the interior of the lower box 1. This structural design allows multiple boxes to be nested and stacked during storage, saving storage space and ensuring that the stack is stable and not easy to tip over. The angle between the side wall of box 1 and the vertical direction is 5°-10°, and the slope of the four side walls of box 1 is consistent. This angle setting makes the nesting and stacking of boxes smoother, while also ensuring that the box has a certain amount of internal space.

[0026] The reinforcing component 2 includes a top frame 21 and a bottom frame 22. Side frames 23 are fixedly installed between the corresponding four corners of the bottom frame 22. The bottom frame 22 is attached to the four bottom sides of the box body 1. The top frame 21 is flush with the four top sides of the box body 1. The side frames 23 are attached to the four corners of the side walls of the box body 1. The top frame, bottom frame and side frames cooperate with each other to support the box body from the top, bottom and four corners, effectively enhancing the overall structural strength of the box body and reducing box body deformation.

[0027] The bottom frame 22 has slots 24 on both the front and back sides, and partitions 25 are inserted between the corresponding slots 24. The partitions can divide the internal space of the box and enable the classification and storage of different items.

[0028] Furthermore, any content not described in detail in this specification is prior art known to those skilled in the art.

[0029] Working principle: The box 1 adopts a square trapezoidal design with a larger top and a smaller bottom, and the side walls are at an angle of 5°-10° to the vertical direction, so that the upper box 1 can be stably inserted into the lower box 1 to complete the stacking; in the internal reinforcing components 2, the bottom frame 22 fits against the bottom of the box, the top frame 21 is flush with the top of the box 1, and the side frame 23 fits against the corner of the side wall. The three work together to enhance the structural strength of the box 1; at the same time, the slot 24 of the bottom frame 22 can be inserted into the partition 25 to realize the internal space classification.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
