[0002] With the continuous development of planting technology, more and more fruits of various forms have entered the public's field of vision. Even for the same type of fruit, the price difference is very large due to various reasons such as origin and planting conditions. Therefore, some scarce fruits are sold by number and are often used for gift giving. Therefore, they need to be packaged in boxes instead of ordinary bags when purchased. And the packaging bags used for fruits need to avoid mechanical damage and ensure ventilation to improve the freshness of the fruit and reduce rot and damage during transportation.

[0003] The patent with publication number CN219770650U in the prior art discloses a fruit packaging box, which relates to the field of packaging technology and is used to improve the packaging efficiency of fruits and ensure the protection effect of fruits. The fruit packaging box includes a box body, a base, a first buffer limit assembly and a second buffer limit assembly. The box body includes a storage cavity. The base is placed in the storage cavity of the box body, and the base is fitted with the inner wall of the storage cavity. The first buffer limit assembly includes a first main body and a first limit through hole running through the thickness direction of the first main body; the first buffer limit assembly is placed on the base and fits with the inner wall of the storage cavity. The second buffer limit assembly includes a second main body and a second limit through hole running through the thickness direction of the second main body; the second buffer limit assembly is located on the side of the first buffer limit assembly away from the base, and the second buffer limit assembly is fitted with the inner wall of the storage cavity.

[0004] Although the above packaging box improves the compression resistance of the packaging box and avoids mutual squeezing between fruits through the buffer limiter component, its ventilation effect is poor.

[0005] Some other packaging boxes often achieve ventilation by directly opening holes on the outside of the box. Such boxes are often single-layered and have limited pressure resistance during transportation. Utility Model Content

[0021] The following is combined with Figure 1-6 The utility model is further described with examples.

[0022] In the description of the present invention, it should be noted that the front, rear and other orientations or positional relationships involved in the orientation description are described as the outer box body 2 having an opening with a taking port 11 on one side facing forward and a second vent 13 on the other side facing backward. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0023] Embodiment 1: A breathable and pressure-proof fruit packaging box, comprising an inner box body 1 and an outer box body 2, wherein the inner box body 1 is provided with a storage cavity 3 opening upward, a breathable and pressure-proof tube 4 and a bottom plate 5 located around the storage cavity 3, as shown in FIG. Figure 4 As shown, the storage cavity 3 is composed of the inner side of the air-permeable pressure-proof tube 4 and the bottom plate 5. The lower end face of the air-permeable pressure-proof tube 4 is fixedly connected to the upper end face of the bottom plate 5. The vertical cross-section of the air-permeable pressure-proof tube 4 is in the shape of a "mouth". The lower end face of the outer side of the air-permeable pressure-proof tube 4 is bent and connected to the outer side of the bottom plate 5. The "mouth" shape can improve the compressive strength of the air-permeable pressure-proof tube 4. The air-permeable pressure-proof tube 4 can be directly formed by bending. After the bending is completed, the side contacting the bottom plate 5 can be fixed by gluing, which is convenient for assembly. Figure 4 As shown, the air-permeable and pressure-proof tube 4 is a hollow structure, and the air-permeable and pressure-proof tube 4 includes a long tube 6 located on the left and right sides of the storage cavity 3 and a short tube 7 on the front and rear sides, the two short tubes 7 are located between the two long tubes 6, and the two long tubes 6 are both provided with openings corresponding to the two short tubes 7. The left and right sides of the two short tubes 7 are connected to the inside of the two long tubes 6, and the front and rear sides of the two long tubes 6 are connected to the outside, and the external air can enter the two short tubes 7 through the two long tubes 6. Figure 1 As shown, the air-permeable and pressure-proof tube 4 is provided with a plurality of air holes 8 on one side surface close to the storage cavity 3, and the air holes 8 are connected to the inside of the air-permeable and pressure-proof tube 4. The air inside the storage cavity 3 can circulate with the air in the air-permeable and pressure-proof tube 4 through the air holes 8, thereby ensuring ventilation and improving the freshness of the fruit. In addition, the air-permeable and pressure-proof tube 4 improves the pressure resistance of the packaging box to avoid damage during transportation. When subjected to pressure from the left and right sides, the short tube 7 mainly plays a supporting role, and when subjected to pressure from the front and back sides, the long tube 6 mainly plays a supporting role. When subjected to pressure from the upper and lower sides, the short tube 7 and the long tube 6 can both play a major supporting role, thereby ensuring that the air-permeable and pressure-proof tube 4 can play a good supporting role for the pressure from all directions to which the packaging box is subjected, thereby improving the pressure resistance of the packaging box to avoid damage during transportation.

[0024] like Figure 1As shown, the inner box body 1 also includes a mesh partition plate 9, which is located inside the storage cavity 3 during transportation. The horizontal area of ​​the partition plate 9 corresponds to the size of the storage cavity 3, and the height of the partition plate 9 is smaller than the height of the storage cavity 3 to ensure that the flow of air inside the storage cavity 3 is not blocked, and the contact parts of the partition plate 9 and the breathable pressure-proof tube 4 are perpendicular to each other to reduce the contact area to reduce the area blocked by the air hole 8, and the partition plate 9 is provided with a plurality of small cavities for storing fruits separately. The partition plate 9 also allows the fruits to be stored independently of each other, and will not be squeezed against each other during transportation to cause damage to the fruits, which is convenient for the transportation of fruits. Figure 5 As shown, the partition plate 9 is provided with fixing strips 14 around it, the lower part of the fixing strips 14 is fixedly connected to the partition plate 9, the upper part of the fixing strips 14 is bonded to the upper end surface of the breathable pressure-proof tube 4, and the fixing strips 14 are L-shaped and fit the outer side of the breathable pressure-proof tube 4. The fixing strips 14 allow the partition plate 9 to be suspended in the middle of the storage cavity 3. By suspending the partition plate 9 in the middle of the storage cavity 3, the efficiency of separating the fruits can be improved to prevent them from rolling from the top of the partition plate into other small cavities during transportation. The fixing strips 14 allow the height of the fruit shielding to be increased without increasing the height of the partition plate 9, which saves materials and reduces the influence of the partition plate 9 on the air circulation inside the storage cavity 3. The fixing strip 14 can adjust the height of the partition 9 by adjusting the position of the sticking part to adapt to fruits of different sizes and types. When the fruit is small in size, the height of the partition 9 can be lowered by the fixing strip 14, and when the fruit is large in size, the height of the partition 9 can be raised by the fixing strip 14.

[0025] like Figure 5 and Figure 6 As shown, the fixing strips 14 are provided with tear lines 15, and when the partition plate 9 is pressed down, the fixing strips 14 can be torn through the tear lines 15. After the fixing plate is torn, the partition plate 9 can be pressed down to the bottom of the storage cavity 3, and at this time, the fruit rises relative to the partition plate 9, which is convenient for users to take.

[0026] like Figure 2 and Figure 3As shown, during transportation, the inner box body 1 is located inside the outer box body 2, and a take-out opening 11 for taking out the inner box body 1 is opened on the front side of the outer box body 2. The outer box body 2 also further strengthens the protection of the fruit. A flip cover 10 is folded and connected to the upper end of the front side of the inner box body 1. The flip cover 10 can be flipped down to close the take-out opening 11. A handle 16 for pulling the inner box body 1 is provided on the front side of the inner box body 1. A magnetic component 17 is provided at the lower part of the take-out opening 11. An iron sheet 18 corresponding to the magnetic component 17 is provided on the inner side of the flip cover. When the flip cover is flipped down and closed, the magnetic component 17 and the iron sheet 18 attract each other, so that the flip cover 10 will not be easily opened during transportation.

[0027] like Figure 2 As shown, the flip cover 10 is provided with a first vent 12 corresponding to the front side of the long tube 6, and the rear side of the outer box body 2 is provided with a second vent 13 corresponding to the rear side of the long tube 6. The first vent 12 and the second vent 13 ensure that when the inner box body 1 is placed inside the outer box body 2, the breathable and pressure-proof tube 4 is still connected to the outside to ensure air circulation.

[0028] like Figure 1 As shown, a transparent plastic observation window 19 is provided on the upper end surface of the outer box body 2, and the transparent plastic observation window 19 is adapted to the storage cavity 3 for observing the fruit placed in the inner box body 1 from the outside.
