Description

Technical Field

[0001] This utility model relates to the field of printed color box technology, specifically a printed color box structure. Background Technology

[0002] Color boxes refer to folding cartons and micro-corrugated cardboard boxes made of two materials: cardboard and micro-corrugated paperboard. They are generally used as a mid-range packaging method, falling between inner and outer packaging and outer cartons. As the name suggests, color boxes typically consist of several colors combined, giving a strong visual impact and allowing buyers and users to better understand the overall appearance and color details of the product. They are particularly suitable for goods that cannot be opened before purchase. They are now widely used in industries such as electronics, food, beverages, alcohol, tea, cigarettes, pharmaceuticals, health products, cosmetics, small appliances, clothing, toys, and sporting goods, as well as in related product packaging industries.

[0003] Most existing color boxes have a simple structure. If the color box is subjected to external pressure or impact during transportation or use, it is easy to be damaged, resulting in damage to the goods inside the color box.

[0004] Therefore, how to design a printing box structure has become a problem we need to solve. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a printed color box structure that solves the problems mentioned in the background section.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a printed color box structure, including a box body and a box lid, wherein the box lid is connected to the top of the box body, and support columns are fixedly connected to the four corners inside the box body. Both the box body and the box lid are made of cardboard, wherein the cardboard includes a first corrugated paper layer, a second corrugated paper layer and a third corrugated paper layer, wherein the first corrugated paper layer is disposed between the second corrugated paper layer and the third corrugated paper layer, wherein the second corrugated paper layer is disposed on the outside of the first corrugated paper layer, and wherein the third corrugated paper layer is disposed on the inside of the first corrugated paper layer; A number of evenly distributed reinforcing ribs are fixedly connected between the first corrugated paper layer and the second corrugated paper layer, an airbag interlayer is fixedly connected between the first corrugated paper layer and the third corrugated paper layer, and reinforcing layers are fixedly connected inside both the second corrugated paper layer and the third corrugated paper layer.

[0007] Preferably, the support column is a memory foam cushioning column.

[0008] Preferably, the reinforcing rib is an EPE foam strip.

[0009] Preferably, the airbag interlayer is a TPU film airbag.

[0010] Preferably, the reinforcing layer is a carbon fiber mesh.

[0011] Preferably, a high-toughness kraft paper is fixedly connected to the outer side of the second corrugated paper layer, and a kraft paper is fixedly connected to the inner side of the third corrugated paper layer.

[0012] (III) Beneficial Effects This utility model provides a printed color box structure, which has the following beneficial effects: This invention, through the setting of support columns, can support the four corners inside the box. When the box is squeezed, the support columns will deform slowly under force, continuously dispersing the pressure and preventing the corners of the box from being subjected to excessive force and excessive deformation.

[0013] This invention, through the arrangement of a first corrugated paper layer, a second corrugated paper layer, and a third corrugated paper layer, provides basic structural support for the color box, giving it a certain degree of pressure resistance. The reinforcing ribs further strengthen the internal structure of the color box, absorbing impact force and enhancing its pressure resistance when subjected to external pressure or impact. The airbag interlayer allows the TPU film airbag to elastically deform under pressure or impact, further improving the box's pressure resistance and preventing damage to the goods inside.

[0014] This invention, through the addition of reinforcing layers, enhances the toughness of the second and third corrugated paper layers, making the color box less prone to tearing from impact and preventing damage to the color box. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", 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 utility model and simplifying the description, and are not intended to indicate or imply that the device or component 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 utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a printed color box structure, including a box body 1 and a box lid 2. The box lid 2 is connected to the top of the box body 1. Support columns 11 are fixedly connected to the four corners inside the box body 1. The support columns 11 are memory foam cushioning columns. By setting the support columns 11, the four corners inside the box body 1 can be supported. When the box body 1 is squeezed, the support columns 11 will deform slowly under force, continuously dispersing the pressure and preventing the corners of the box body 1 from being subjected to excessive force and excessive deformation.

[0021] Specifically, both the box body 1 and the box lid 2 are made of cardboard 3. Cardboard 3 includes a first corrugated paper layer 31, a second corrugated paper layer 32, and a third corrugated paper layer 33. The first corrugated paper layer 31 is located between the second corrugated paper layer 32 and the third corrugated paper layer 33. The second corrugated paper layer 32 is located on the outside of the first corrugated paper layer 31, and the third corrugated paper layer 33 is located on the inside of the first corrugated paper layer 31. The arrangement of the first corrugated paper layer 31, the second corrugated paper layer 32, and the third corrugated paper layer 33 provides basic structural support for the color box, giving the color box a certain degree of pressure resistance. High-toughness kraft paper 37 is fixedly connected to the outside of the second corrugated paper layer 32, and the color-printed pattern is set on the surface of the high-toughness kraft paper 37. The arrangement of the high-toughness kraft paper 37 provides basic toughness support for the outer surface of the color box. Kraft paper 38 is fixedly connected to the inside of the third corrugated paper layer 33. The arrangement of the kraft paper 38 ensures the flatness of the inner surface of the color box.

[0022] Specifically, a number of evenly distributed reinforcing ribs 34 are fixedly connected between the first corrugated paper layer 31 and the second corrugated paper layer 32. The reinforcing ribs 34 are EPE foam strips, which are fixed by hot melt adhesive. The reinforcing ribs 34 can strengthen the internal structure of the color box and further absorb the impact force when the color box is squeezed or hit by the outside, thus improving the pressure resistance of the color box.

[0023] Specifically, an airbag interlayer 35 is fixedly connected between the first corrugated paper layer 31 and the third corrugated paper layer 33. The airbag interlayer 35 is a TPU film airbag. With the setting of the airbag interlayer 35, when the color box is subjected to external pressure or impact, the TPU film airbag will undergo elastic deformation, further improving the pressure resistance of the color box and preventing damage to the goods inside the color box.

[0024] Specifically, a reinforcing layer 36 is fixedly connected inside the second corrugated paper layer 32 and the third corrugated paper layer 33. The reinforcing layer 36 is a carbon fiber mesh. By setting the reinforcing layer 36, the toughness of the second corrugated paper layer 32 and the third corrugated paper layer 33 can be enhanced, making the color box less likely to be torn by impact and avoiding damage to the color box.

[0025] The working process of this utility model is as follows: The support columns 11 provide support for the four corners of the box body 1. When the box body 1 is compressed, the support columns 11 deform slowly under pressure, continuously dispersing the pressure and preventing excessive deformation at the corners of the box body 1. The first corrugated paper layer 31, the second corrugated paper layer 32, and the third corrugated paper layer 33 provide basic structural support for the color box, giving it a certain degree of compressive strength. The high-toughness kraft paper 37 provides basic toughness support for the outer surface of the color box. The reinforcing layer 36 enhances the toughness of the second corrugated paper layer 32 and the third corrugated paper layer 33, making the color box less prone to tearing from impact and preventing damage. The reinforcing ribs 34 strengthen the internal structure of the color box, further absorbing impact force and improving its compressive strength when the color box is subjected to external pressure or impact. The airbag interlayer 35 provides additional support when the color box is subjected to external pressure or impact. The thin film airbag undergoes elastic deformation, further enhancing the pressure resistance of the color box and preventing damage to the goods inside.
