Description

Technical Field

[0001] The utility model relates to the field of packaging tools, in particular to a packaging box. Background Art

[0002] The packaging box is the most common packaging tool in life. It plays a packaging function for the product. On the one hand, it makes the product more beautiful and convenient for handling. On the other hand, the packaging box also has the function of protecting the product, so that the product is not easily damaged during transportation.

[0003] Among the existing packaging boxes, plastic packaging boxes are common packaging boxes, but single-layer plastic packaging boxes have poor strength. If a metal reinforcement layer is provided in the plastic packaging box, the weight and cost of the packaging box will increase, and the economic efficiency will deteriorate. Therefore, there is an urgent need for a packaging box with low cost and better strength than a single-layer plastic box. Utility Model Content

[0004] Based on the above situation, the main purpose of the utility model is to provide a packaging box to solve the problem that the single-layer plastic packaging box has poor strength. If a metal reinforcement layer is provided in the plastic packaging box, the weight and cost of the packaging box will increase, and the economic efficiency will deteriorate.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A packaging box comprises a plastic layer and a honeycomb paper layer;

[0007] The plastic layer comprises at least two layers, the honeycomb paper layer comprises at least one layer, and the honeycomb paper layer is fixed between the two plastic layers.

[0008] Preferably, the plastic layer is provided with three layers, and the honeycomb paper layer is provided with two layers;

[0009] The plastic paper layer and the honeycomb paper layer are arranged in sequence from the inside to the outside of the box body.

[0010] Preferably, the three plastics are two exposed plastic layers and an internal plastic layer;

[0011] The exposed plastic layer is located at the inner and outer sides of the box body, and the built-in plastic layer is fixed between the two honeycomb paper layers.

[0012] Preferably, the thickness of the exposed plastic layer is 2-4 mm;

[0013] The thickness of the built-in plastic layer is 1-2 mm, and the thickness of the honeycomb paper layer is 1-3 mm.

[0014] Preferably, a finishing layer is provided on the upper side of the box body, the upper side of the finishing layer is a smooth surface, and the lower side of the finishing layer is a rough surface.

[0015] The beneficial effects of the utility model are as follows: the honeycomb structure is used to improve the strength of the packaging box. While having good strength, it can also keep the internal products warm and moisture-proof, so that the internal products can be packaged in a relatively stable state. In addition, the weight of the honeycomb board is lighter than that of metal, the cost is lower, and it has excellent economy.

[0016] Other beneficial effects of the utility model will be explained through the introduction of specific technical features and technical solutions in the specific implementation manner. Through the introduction of these technical features and technical solutions, those skilled in the art should be able to understand the beneficial technical effects brought about by the technical features and technical solutions.

[0021] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0022] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0023] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0024] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0025] Reference Figure 1-2The utility model provides a packaging box, including multiple plastic layers 1 and one or more honeycomb paper layers 2, the honeycomb paper layer 2 is fixed to the inner side of the plastic layer 1, and is used to improve the strength of the packaging box, while being able to reduce the weight of the packaging box and reduce the production cost of the packaging box.

[0026] The plastic layer 1 is provided with at least two layers, which are respectively provided on the inner and outer sides of the packaging box body, and the honeycomb paper layer 2 is provided with at least one layer, and the honeycomb paper layer 2 is fixed between the two plastic layers 1. The honeycomb structure is used to improve the strength of the packaging box. While having good strength, it can also play a role in heat preservation and moisture resistance for the internal products, so that the internal products can be stored and packaged in a relatively stable state. In addition, the weight of the honeycomb board is lighter than that of metal, the cost is lower, and it has excellent economic efficiency.

[0027] Furthermore, the plastic layer 1 has three layers, the honeycomb paper layer 2 has two layers, and the plastic paper layer and the honeycomb paper layer 2 are arranged in sequence from the inside to the outside, that is, the two honeycomb paper layers 2 are sandwiched at the gap position between the three plastic layers 1. By arranging multiple layers of honeycomb paper layers 2, the strength of the packaging box can be improved. However, after the length of the honeycomb paper layer 2 is increased or multiple layers are directly superimposed, the strength of the interface between the two honeycomb paper layers 2 on the side close to each other is weak. Therefore, a plastic layer 1 is added between the two to stabilize the two honeycomb paper layers 2 respectively, so that the packaging box has better strength.

[0028] As an embodiment, the plastic layer 1 and the honeycomb paper layer 2 are fixed by gluing, so that the layer structures can be fixed at a lower cost.

[0029] As an embodiment, the three-layer plastic layer 1 is composed of two exposed plastic layers 11 and an internal plastic layer 12. The exposed plastic layer 11 is located on both sides of the inner and outer sides of the box body and is directly arranged on the outside. The internal plastic layer 12 is fixed between the two honeycomb paper layers 2. The thickness of the exposed plastic layer 11 is 1-2 mm, the thickness of the internal plastic layer 12 is 2-4 mm, and the thickness of the honeycomb board layer is 2-4 mm, so that the packaging box can have good strength.

[0030] As an embodiment, a finishing layer 3 is provided at the upper end of the outer box body, the upper side of the finishing layer 3 is a smooth surface, and the lower side of the finishing layer 3 is a rough surface. The rough surface can be used for coating glue to bond and fix the plastic layer 1 and the honeycomb paper layer 2, thereby improving the bonding strength between the plastic layer 1 and the honeycomb paper layer 2, improving the integrity of the interior of the box body, and improving the strength of the packaging box.

[0031] The implementation principle of the utility model is: the honeycomb structure is used to improve the strength of the packaging box. While having good strength, it can also keep the internal products warm and moisture-proof, so that the internal products can be packaged in a relatively stable state. In addition, the weight of the honeycomb paperboard 2 is lighter than that of metal, the cost is lower, and it has excellent economy.

[0032] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0033] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
