Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a corrugated paper box which is convenient to use. Background Art

[0002] Corrugated boxes are made of corrugated paperboard through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and the usage has always been the first among all kinds of packaging products. With its superior performance and good processing performance, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers and become the main force of transport packaging. It has the characteristics of protecting goods, facilitating warehousing and transportation; corrugated boxes can be used to transport fruits, thereby reducing collision or friction between fruits and protecting them.

[0003] With respect to the above-mentioned related technologies, the inventors found that the existing corrugated paper boxes used to transport fruits are usually sealed with tape, which makes opening inconvenience poor, and the fruits near the bottom of the corrugated paper boxes are in a closed environment, which is prone to corruption due to lack of air circulation, thus shortening the shelf life of the fruits. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a corrugated paper box which is easy to use. The flip-type limiting plates at both ends of the flip fixing plate are rotated and extended into the limiting cavity, so that the snap-on cover plate assembly can seal the opening of the paper box body, thereby enhancing the convenience of opening and closing. In addition, the circular holes, air flow gaps and air circulation channels are connected to each other, so that the environment at the bottom of the corrugated paper box can generate air flow with the environment outside it, thereby reducing the probability of rapid corruption of fruits and extending the storage time of fruits.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a convenient corrugated paper box, comprising: a paper box body, a long side of the top of the paper box body is connected to a snap-on cover plate assembly, the side of the snap-on cover plate assembly away from the paper box body is connected to a flip fixing plate, and both ends of the flip fixing plate are respectively connected to flip limit plates;

[0006] The inner cavity of the carton body is provided with a U-shaped inner lining plate, and L-shaped plates are respectively provided on both sides of the U-shaped inner lining plate, a connecting plate is connected between the top of the L-shaped plate and the U-shaped inner lining plate, and a limiting cavity adapted to the flip-type limiting plate is provided between the L-shaped plate and the side wall of the carton body, and the horizontal side edge of the L-shaped plate is fixedly connected to the bottom of the carton body;

[0007] The bottom of the U-shaped inner lining plate is provided with a plurality of circular holes at intervals, an air flow gap is provided between the bottom of the U-shaped inner lining plate and the bottom wall of the carton body, and an air circulation channel is provided between the air flow gap and the external space of the carton body;

[0008] An elastic supporting component is connected to the bottom center of the U-shaped inner lining plate, which is suitable for preventing the U-shaped inner lining plate from bending and deforming due to pressure.

[0009] By adopting the above technical scheme, when in use, fruits can be placed in the carton body, and the fruits fall on the bottom wall of the U-shaped inner lining plate. Since the U-shaped inner lining plate is connected to the L-shaped plate through the connecting plate, and the horizontal side of the L-shaped plate is fixedly connected to the bottom of the carton body, the U-shaped inner lining plate and the carton body are relatively fixed, and the U-shaped inner lining plate plays a bearing role for the fruits. The elastic support component is connected between the U-shaped inner lining plate and the bottom of the carton body, and the elastic support component plays an elastic supporting role, preventing the U-shaped inner lining plate from being subjected to pressure and producing a large bending deformation, and reducing the vibration caused by the bumpy road surface during transportation from being transmitted to the fruits; since the circular hole, the air flow gap and the air circulation flow channel are connected, the environment at the bottom of the corrugated carton can generate air flow with the environment outside it, reducing the probability of rapid corruption of the fruit and extending the shelf life of the fruit; the flip-type limit plates at both ends of the flip fixing plate are rotated and extended into the limit cavity, so that the snap-on cover assembly can seal the opening of the carton body, thereby enhancing the convenience of opening and closing.

[0010] In a preferred example, the utility model can be further configured as follows: the snap-on cover assembly includes a cover body and baffles connected to both ends of the cover body, and the baffles can extend into the inner cavity of the carton body.

[0011] By adopting the above technical solution, the baffles at both ends of the cover body extend into the inner cavity of the carton body, reducing the gap between the cover body and the carton body, and preventing a large displacement between the cover body and the carton body.

[0012] In a preferred example, the utility model can be further configured as follows: the air circulation channel includes a plurality of ventilation holes arranged at intervals on the front and rear sides of the carton body, and the ventilation holes are connected to the air flow gap.

[0013] By adopting the above technical solution, the vents, air flow gaps and circular holes are connected, so that air circulation occurs between the inner cavity of the U-shaped lining plate and the outside of the carton body, which reduces the probability of rapid corruption of the fruit and prolongs the shelf life of the fruit.

[0014] In a preferred example, the utility model can be further configured as follows: the elastic support component includes an upper strip plate and a lower strip plate, a plurality of rubber columns are spaced apart and connected between the upper strip plate and the lower strip plate, the upper strip plate is connected to the bottom plane of the U-shaped inner lining plate, and the lower strip plate is contact-connected to the bottom of the carton body.

[0015] By adopting the above technical solution and using rubber columns, the bottom of the carton body has an indirect buffering effect on the U-shaped inner lining plates, thereby reducing the vibration caused by the bumpy road surface during transportation and transmitting it to the fruit.

[0016] In a preferred example, the utility model can be further configured as follows: the outer surface of the horizontal edge of the L-shaped plate is connected with a wear-resistant layer.

[0017] By adopting the above technical solution, when a corrugated paper box on the ground is moved, the friction between the corrugated paper box and the ground is reduced through the effect of the wear-resistant layer, thereby extending the service life of the corrugated paper box.

[0018] In summary, the utility model includes at least one of the following beneficial technical effects:

[0019] 1. The flip limit plates at both ends of the flip fixed plate rotate and extend into the limit cavity, so that the snap-on cover assembly seals the opening of the carton body, thereby enhancing the convenience of opening and closing the snap-on cover assembly.

[0020] 2. The circular holes, air flow gaps and air circulation channels are connected, so that the environment at the bottom of the corrugated box can generate air flow with the environment outside, reducing the probability of rapid corruption of fruits and extending the shelf life of fruits.

[0021] 3. Since the elastic support component is connected between the U-shaped inner lining plate and the bottom of the carton body, the elastic support component plays an elastic support role, preventing the U-shaped inner lining plate from being subjected to pressure and causing a large bending deformation, and reducing the vibration generated by the bumpy road surface during transportation from being transmitted to the fruit.
