Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a breathable color-printed packaging box. Background Art

[0002] With the development of social economy and the improvement of people's living standards, packaging boxes, as an important packaging material, are widely used in the storage and transportation of various products. In particular, color-printed packaging boxes not only protect products, but also enhance the appearance value of products and market competitiveness through exquisite printing patterns and designs. However, there are some problems in the use of existing color-printed packaging boxes, especially in terms of air permeability, which affects the actual use effect of the packaging boxes.

[0003] Traditional color-printed packaging boxes are usually made of paper or plastic materials, which have good sealing properties and can effectively prevent external moisture from entering the packaging box. However, too high sealing also leads to poor air circulation in the box. Especially during storage and transportation, the internal humidity is difficult to dissipate, which can easily cause the items in the box to get damp and moldy, affecting the quality and service life of the product. This problem is particularly prominent for some humidity-sensitive products, such as food and medicine. Therefore, how to ensure the sealing of the packaging box while enhancing its air permeability has become a technical problem that needs to be solved urgently.

[0004] In order to solve the above problems, some designs of breathable packaging boxes have appeared in the prior art. These designs usually set air holes in certain parts of the packaging box to achieve air exchange inside and outside the box. However, it is often difficult to achieve the ideal ventilation effect by simply setting air holes. On the one hand, the number and distribution of air holes need to be precisely controlled, otherwise it is easy to affect the overall strength and appearance of the packaging box; on the other hand, the simple air hole design cannot effectively prevent external moisture and dust from entering the packaging box, and there are still certain limitations in use.

[0005] In view of this, the inventor specially designed a breathable color-printed packaging box, and this case was thus created. Utility Model Content

[0017] In a further solution, an interlayer plate is further included, a card slot is arranged on the box bottom, and one end of the interlayer plate is adapted to the shape of the card slot and is extended to be provided with a card tongue for engaging with the card slot.

[0018] In a further embodiment, the channel width and depth of the air guide groove are 5-10 mm.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] The invention significantly improves the air permeability of the packaging box by opening air holes on the box cover and the side panels and hot pressing the air permeable film inside the air holes. In particular, the use of PTFE film, due to its excellent air permeability and waterproof properties, can effectively prevent moisture from entering the box, while allowing air to circulate freely, preventing the items in the box from getting damp and moldy, and extending the shelf life of the items in the package.

[0022] Air guide grooves are glued to the inside of the box cover and the side panels to guide the air to circulate inside the box.

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0031] like Figure 1 and Figure 3 As shown, the utility model provides a breathable color printing packaging box, including a box body 1 composed of a box cover 11, a box bottom 12 and a box side plate 13. The box cover 11 and the box side plate 13 are provided with air holes 2. The inner side of the air hole 2 is hot-pressed to connect the air permeable membrane 3. The air permeable membrane 3 is a PTFE membrane, which significantly improves the air permeability of the packaging box. The selected PTFE membrane, due to its excellent air permeability and waterproof performance, can effectively prevent moisture from entering the box, while allowing air to circulate freely, preventing the items in the box from getting damp and moldy, and extending the shelf life of the items in the package.

[0032] like Figure 3 As shown, air guide grooves 4 for guiding air to circulate inside the box body 1 are glued to the inner side of the box cover 11 and the box side panels 13. By providing the wavy air guide grooves 4, the air circulation path is increased, ensuring that the air circulates fully in the box, avoiding air stagnation, improving the overall ventilation effect, and ensuring that the items in the box are in a dry state. The air guide grooves 4 are wavy, and the wavy channel design breaks the single air flow path, avoiding air stagnation in the box, and preventing the items from getting damp and moldy.

[0033] The width and depth of the air guide groove 4 are 5-10 mm. The width and depth of 5-10 mm can provide a sufficient air flow cross section to ensure that the air flows smoothly in the guide groove without obstruction of air flow due to the narrow channel.

[0034] like Figure 2 As shown, the vent holes 2 are provided with vent adjusters 5, and the user can adjust the opening and closing degree of the vent holes 2 according to actual needs, thereby controlling the air flow rate of the box body 1. The vent holes 2 are arranged in a circular array, and the vent adjuster 5 includes a circular plate 51, on which are provided adjustment vent holes 53 having the same number and arrangement as the vent holes 2, and a rotating shaft 52 is provided at the center of the circular plate 51. The opening and closing of the vent holes 53 can be adjusted by rotating the circular plate 51, which is easy to operate and adapts to different storage and transportation environment requirements.

[0035] like Figure 3 As shown, a plurality of reinforcing ribs 6 are provided inside the box side panels 13, which effectively enhance the structural strength of the box body 1 and prevent the box body 1 from being deformed due to external pressure during storage and transportation. This ensures the firmness of the packaging box and increases its service life.

[0036] like Figure 1 and Figure 2 As shown, a label shell 7 is attached to the surface of the box cover 11, and a label card can be conveniently inserted to identify the type and quantity of the items in the box. The label shell 7 is made of transparent plastic material, which is both beautiful and practical, and improves the user experience of the packaging box.

[0037] like Figure 4 As shown, the packaging box further includes an interlayer plate 8, a card slot 121 is provided on the box bottom 12, and a card tongue 81 is extended to fit the card slot 121 at one end of the interlayer plate 8. By providing the interlayer plate 8, different articles can be flexibly separated to prevent the articles from being squeezed and damaged by each other. At the same time, the card connection design facilitates the user to adjust the position and number of the interlayer plate 8 as needed, thereby improving the applicability and flexibility of the packaging box.

[0038] In summary, the breathable color-printed packaging box of the utility model significantly improves the breathability through a variety of structural designs, prevents items from getting damp and moldy, and at the same time maintains the aesthetics and structural strength of the packaging box, and has good application prospects.

[0039] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
