Description

Technical Field

[0001] This utility model belongs to the field of paper box technology, specifically relating to a portable, pressure-resistant corrugated box. Background Technology

[0002] Currently, portable, pressure-resistant corrugated boxes are widely used in product packaging and short-distance transportation due to their lightweight, low cost, and easy recyclability. However, existing corrugated box designs have significant limitations: most are formed by folding a single corrugated cardboard, resulting in insufficient overall strength. When loaded with heavy items, problems such as box deformation and side panel bulging easily occur, affecting safety. Some reinforced corrugated boxes increase strength by increasing cardboard thickness, leading to increased material consumption, inconvenient folding and assembly, and increased overall weight, diminishing their portability advantage. Furthermore, existing box components lack effective support structures at joints, making it easy for the lid to loosen after closing, hindering the formation of a stable whole and offering limited protection for the contents.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] like Figure 1-3 As shown, a portable, pressure-resistant corrugated box includes a box body 1. Several folding covers are sequentially connected around the upper perimeter of the box body 1. Two opposing folding covers are designated as inward folding covers 2, and two other opposing folding covers are designated as outward folding covers 3. An inner indentation 4 is provided on the inner side of the connection between the folding covers and the box body 1. A carrying handle 5 is attached to the outward folding cover 3, and an outer indentation 6 is provided between the outward folding cover 3 and the carrying handle 5. The carrying handle 5 has a handle opening 7. Several reinforcing plates 8 are provided inside the box body 1, and the reinforcing plates 8 are fixedly connected to the box body 1. The box body 1, folding covers, and carrying handle 5 are made of corrugated cardboard, while the reinforcing plates 8 are made of plastic. The handle opening 7 on the carrying handle 5 allows the hand to reach in. The inward folding covers 2 and the outward folding covers 3 form a multi-layered top cover structure, improving pressure resistance. The reinforcing plates 8 strengthen the structural strength of the box body, further improving its pressure resistance.

[0016] Furthermore, the box body 1 includes a bottom plate 10 and four side plates 9. The box body 1 is integrally formed from corrugated cardboard. An inner indentation 4 is provided between the bottom plate 10 and the side plates 9. The folding cover corresponds to and is connected to the corresponding side plates 9. Several reinforcing plates 8 are provided on the bottom plate 10, the side plates 9 and the folding cover. The reinforcing plates 8 are bonded to the bottom plate 10, the side plates 9 or the folding cover.

[0017] Furthermore, the reinforcing plate 8 on the base plate 10 corresponds to the reinforcing plate 8 on the side plate 9, and the reinforcing plate 8 on the side plate 9 corresponds to the reinforcing plate 8 on the folding cover. A support structure is provided between the reinforcing plate 8 on the base plate 10 and the corresponding reinforcing plate 8 on the side plate 9. The reinforcing plate 8 on the side plate 9 corresponds to the reinforcing plate 8 on the folding cover, and a support structure is provided between the reinforcing plate 8 on the side plate 9 and the corresponding reinforcing plate 8 on the folding cover. The support structure includes a support slope 11 located at one end of the reinforcing plate 8, and the support slope 11 at one end of the reinforcing plate 8 fits into the support slope 11 at one end of the adjacent reinforcing plate 8. The support structure allows the adjacent reinforcing plates 8 to cooperate with each other, improving the compressive strength of the corrugated box. The reinforcing plate 8 at the support slope 11 is thickened, preferably with an isosceles trapezoidal protrusion. The reinforcing plates 8 are connected in sequence to form a frame, creating a reinforcing effect on the same vertical plane, improving the compressive strength of the box body 1.

[0018] Furthermore, a gap 12 is provided between the two inward folding cover plates 2, and the reinforcing plate 8 on the outward folding cover plate 3 is located in the gap 12. The gap 12 provides space for the reinforcing plate 8 on the outward folding cover plate 3 to be accommodated, preventing the reinforcing plate 8 on the outward folding cover plate 3 from directly pressing on the inward folding cover plate 2 and causing the outward folding cover plate 3 to fail to remain flat.

[0019] Furthermore, adjacent side panels 9 are bonded together. The connection between side panels 9 can also employ other conventional cardboard box connection methods.

[0020] It is worth mentioning that the technical features of corrugated cardboard, corrugated nails, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement methods of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0021] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
