Description

Technical Field

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

[0002] Food storage cartons are paper containers specifically designed for packaging and storing food. They are typically made of kraft paperboard, corrugated cardboard, etc. Kraft paperboard has high strength and toughness, is wear-resistant and tear-resistant, and can effectively protect food from external damage during transportation and storage. Corrugated cardboard consists of one or more layers of corrugated core paper sandwiched between two layers of flat cardboard, and has good cushioning performance, which can reduce the impact on food.

[0003] Currently used cardboard boxes have limited strength during use, especially in logistics and transportation. They are usually stacked in multiple layers, and the bottom cardboard box has to bear the weight of the upper layers. Under long-term stacking, the corrugated structure of ordinary cardboard boxes is easily compressed and deformed, resulting in a sharp drop in compressive strength and the phenomenon of the bottom box collapsing. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A food storage cardboard box, comprising:

[0006] The box body has four corner protectors connected to the inner wall corners. Five third elongated holes and five second elongated holes are respectively opened on the left and right sides of the corner protectors. A short plate is inserted into a pair of the third elongated holes, and a long plate is inserted into a pair of the second elongated holes. A positioning mechanism is provided inside the corner protectors.

[0007] The bottom surface of the inner wall of the box is provided with a first moisture-proof mechanism;

[0008] The box is equipped with a second moisture-proof mechanism on both the left and right sides.

[0009] In one possible implementation, the positioning mechanism includes a pair of first elongated holes formed inside the corner protector, the pair of first elongated holes being connected to a second elongated hole and a third elongated hole respectively, and an insert plate being connected through the interior of the first elongated holes.

[0010] In one possible implementation, positioning holes are provided at both ends of the short plate and the long plate, and the insert plate passes through the interior of the positioning holes.

[0011] In one possible implementation, the five third elongated holes and the five second elongated holes are vertically equidistant.

[0012] In one possible implementation, the first moisture-proof mechanism includes a base plate with eight grooves on the top, and a desiccant bag is connected inside the grooves.

[0013] In one possible implementation, the second moisture-proof mechanism includes a pair of vents on the left and right sides of the box, and a one-way breathable membrane is connected to the inner wall of the box near the vents.

[0014] In one possible implementation, the outer side of the housing is coated with a polyethylene film.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By installing four corner protectors at the corners of the inner wall of the box, the impact force at the corners can be directly absorbed, such as collisions during handling and drop impacts. Five third elongated holes and five second elongated holes are opened on the left and right sides of the corner protectors, and short and long plates are inserted into the third and second elongated holes. The corner protectors at the four corners and the short and long plates on the adjacent sides form a rectangular frame structure. The impact energy is consumed by the elastic deformation of the plates on both sides, reducing damage to the internal goods and achieving the effect of impact protection.

[0017] 2. By setting a bottom plate on the inner wall of the box and placing multiple desiccant packs on top of the bottom plate, the box can actively absorb moisture, preventing it from softening due to moisture absorption and further improving its strength.

[0018] 3. By opening ventilation holes on both sides of the box and installing a one-way breathable membrane inside the ventilation holes, when the humidity inside the box is high, the micropores of the membrane material allow water vapor molecules to diffuse outward, which helps to reduce the risk of moisture inside the box. On the other hand, external rainwater, fog and other liquid water cannot enter the box through the pores of the membrane material, avoiding the external humid environment from directly affecting the carton and goods.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This application provides a food storage cardboard box, which solves the problems in the prior art.

[0029] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0030] like Figures 1-5 As shown, a food storage cardboard box includes:

[0031] Box 6, with four corner guards 3 connected to the inner wall corners. Five third elongated holes 11 and five second elongated holes 9 are respectively opened on the left and right sides of the corner guards 3. A short plate 1 is inserted into the inside of a pair of third elongated holes 11, and a long plate 2 is inserted into the inside of a pair of second elongated holes 9. A positioning mechanism is set inside the corner guards 3.

[0032] The bottom surface of the inner wall of the box 6 is equipped with a first moisture-proof mechanism;

[0033] A second moisture-proof mechanism is provided on both the left and right sides of the box 6.

[0034] In some examples, the positioning mechanism includes a pair of first elongated holes 8 inside the corner protector 3. The pair of first elongated holes 8 are connected to the second elongated hole 9 and the third elongated hole 11 respectively. An insert plate 10 is connected through the inside of the first elongated hole 8. By inserting the insert plate 10 into the top of the corner protector 3 and extending it into the inside of the short plate 1 and the long plate 2, it is beneficial to complete the positioning of the short plate 1 and the long plate 2 and improve the stability of the overall frame.

[0035] In some examples, positioning holes 12 are provided at both ends of the short plate 1 and the long plate 2, and the insert plate 10 passes through the interior of the positioning holes 12.

[0036] In some examples, the five third elongated holes 11 and the five second elongated holes 9 are vertically equidistant.

[0037] In some examples, the first moisture-proof mechanism includes a base plate 7, the top of which has eight grooves 14. The inside of the grooves 14 is connected to a desiccant pack 13, which is usually filled with a moisture-absorbing material such as silica gel, montmorillonite, or calcium chloride to absorb moisture from the air.

[0038] In some examples, the second moisture-proof mechanism includes a pair of vents 4 on the left and right sides of the box body 6. A one-way breathable membrane 5 is connected to the inner wall of the box body 6 near the vents 4. When the humidity inside the box is high, the micropores of the membrane allow water vapor molecules to diffuse outward, which helps to reduce the risk of moisture inside the box. On the other hand, external rainwater, fog and other liquid water cannot enter the box through the pores of the membrane, thus avoiding the external humid environment from directly affecting the carton and goods.

[0039] In some examples, the outer side of the housing 6 is coated with a polyethylene film layer 15, which helps to form a physical barrier to block moisture.

[0040] This utility model, by installing four corner protectors 3 at the corners of the inner wall of the box 6, can directly absorb the impact force at the corners, such as collisions during handling and drop impacts. Five third elongated holes 11 and five second elongated holes 9 are respectively opened on the left and right sides of the corner protectors 3. Short plates 1 and long plates 2 are inserted into the third elongated holes 11 and second elongated holes 9, so that the corner protectors 3 at the four corners and the adjacent short plates 1 and long plates 2 form a rectangular frame structure. The elastic deformation of the side plates dissipates the impact energy, reducing damage to the internal goods and achieving an impact-resistant protection effect. Furthermore, through… A bottom plate 7 is installed on the bottom surface of the inner wall of the box 6, and multiple desiccant packs 13 are installed on the top of the bottom plate 7. This helps to actively absorb moisture inside the box, prevent the box 6 from absorbing moisture and softening, and further improve the strength of the box 6. Then, by opening ventilation holes 4 on both sides of the box 6, and installing a one-way breathable membrane 5 inside the ventilation holes 4, when the humidity inside the box is high, the micropores of the membrane material allow water vapor molecules to diffuse outward, which helps to reduce the risk of moisture inside the box. On the other hand, external rainwater, fog and other liquid water cannot enter the box through the pores of the membrane material, avoiding the external humid environment from directly affecting the carton and goods.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
