Description

Technical Field

[0001] This utility model relates to the field of corrugated paper packaging box technology, specifically a corrugated paper packaging box with a moisture-proof inner coating. Background Technology

[0002] Corrugated cardboard boxes are packaging containers made primarily of corrugated cardboard, a composite material consisting of one or more layers of corrugated core paper bonded together with one or more layers of sheet paper (coating paper, liner paper) using adhesives. This structure gives the packaging box good strength, elasticity, and cushioning properties, effectively protecting the product inside.

[0003] Regarding the existing related technologies, the inventor believes that the following defects exist: the cavity side panels of existing corrugated cardboard packaging boxes are usually only supported by a single layer of cardboard. When fruit is transported inside the packaging box, the single-layer cardboard packaging box has poor compression resistance, which makes the packaging box easy to deform under pressure, thereby damaging the fruit stored inside. Utility Model Content

[0004] To address the technical problem that existing single-layer cardboard packaging boxes have poor compression resistance, leading to easy deformation under pressure and damage to the fruit stored inside, this utility model provides a corrugated cardboard packaging box with a moisture-proof inner coating.

[0005] This utility model is achieved by the following technical solution: a corrugated paper packaging box with a moisture-proof inner coating, including a box body and a box lid, the box lid being located on the top of the box body, the box body including an outer cardboard and an inner cardboard, the inner side of the inner cardboard being processed with multiple slots, the slots being internally connected to a horizontal plate, and the top of the horizontal plate being snapped to a vertical plate.

[0006] Preferably, a cavity is provided between the outer cardboard and the inner cardboard, and a plurality of support blocks are provided inside the cavity, with one end of each support block fixedly connected between the outer cardboard and the inner cardboard.

[0007] Preferably, the top of the horizontal plate is machined with a plurality of first slots, and the bottom of the vertical plate is machined with a second slot, wherein the first slots and the second slots are connected to each other by a snap-fit ​​mechanism.

[0008] Preferably, the horizontal and vertical plates are perpendicular to each other.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] When in use, this utility model uses a double-layer design of outer and inner cardboard to make the box more resistant to pressure. When the outside of the box is hit, the outer cardboard will deform first, and the cavity between the outer and inner cardboard will act as a buffer for the outer cardboard, thus better protecting the fruit inside the inner cardboard.

[0011] In use, this utility model has multiple slots, and the two ends of the horizontal plate are inserted into the slots, so the position of the horizontal plate can be adjusted to suit the size of the fruit, thereby better protecting the fruit inside the box.

[0012] When in use, the horizontal and vertical plates are perpendicular to each other, which makes them act as two reinforcing ribs to support the inside of the box, thereby improving the box's resistance to pressure and reducing damage to fruit during transportation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1: Please refer to Figure 1 - Figure 4 This embodiment of a corrugated cardboard packaging box with a moisture-proof inner coating includes a box body 1 and a box lid 2. The box lid 2 is located on the top of the box body 1. The box body 1 includes an outer cardboard 3 and an inner cardboard 4. The inner cardboard 4 has multiple slots 7 processed on its inner side. A horizontal plate 5 is inserted into the slot 7, and a vertical plate 6 is snapped into the top of the horizontal plate 5.

[0020] The double-layer design of the outer cardboard 3 and the inner cardboard 4 gives the box body 1 a stronger pressure resistance. The inner side of the inner cardboard 4 is provided with a moisture-proof inner coating. Since there is a cavity between the outer cardboard 3 and the inner cardboard 4, and multiple support blocks 10 are fixed inside the cavity, when the outside of the box body 1 is hit, the outer cardboard 3 will deform first. The cavity between the outer cardboard 3 and the inner cardboard 4 will buffer the outer cardboard 3, thereby better protecting the fruit inside the inner cardboard 4.

[0021] Secondly, by setting multiple slots 7, the two ends of the horizontal plate 5 are inserted into the slots 7, so that the position of the horizontal plate 5 can be adjusted, which is convenient to make corresponding adjustments according to the size of the fruit, thereby better protecting the fruit inside the box 1. After the fruit at the bottom of the box 1 is placed, a divider is placed, so that the horizontal plate 5 can be inserted again, making it convenient to place two layers of fruit.

[0022] Furthermore, the top of the horizontal plate 5 is machined with multiple first slots 8, and the bottom of the vertical plate 6 is machined with second slots 9. The first slots 8 and the second slots 9 are interlocked with each other. The horizontal plate 5 and the vertical plate 6 are perpendicular to each other, so that the horizontal plate 5 and the vertical plate 6 are equivalent to two reinforcing ribs to provide support for the interior of the box body 1, thereby improving the pressure resistance of the box body 1 and reducing damage during fruit transportation.

[0023] Working principle: The double-layer design of the outer cardboard 3 and the inner cardboard 4 makes the box body 1 more resistant to pressure. When the outside of the box body 1 is hit, the outer cardboard 3 will deform first. The cavity between the outer cardboard 3 and the inner cardboard 4 will act as a buffer for the outer cardboard 3, thus better protecting the fruit inside the inner cardboard 4. With multiple slots 7, the two ends of the horizontal plate 5 are inserted into the slots 7, so the position of the horizontal plate 5 can be adjusted according to the size of the fruit, thus better protecting the fruit inside the box body 1. The horizontal plate 5 and the vertical plate 6 are perpendicular to each other, thereby improving the pressure resistance of the box body 1 and reducing damage to the fruit during transportation.

[0024] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
