[0002] At present, when making environmentally friendly paper packaging box sheets with transition sheets at the four corners of the packaging box, adhesive sheets are set on the sides of the transition sheets or the box edge sheets. During the bonding work, since the transition sheets are inclined with respect to the horizontal plane, it is very inconvenient for the automated machinery to bond, and the design difficulty of the automated machinery is also great. Moreover, if the pressing plate is not aligned with the bonding position of the adhesive sheet, the bonding will be loose. Therefore, it is necessary to involve a packaging box sheet structure that is convenient for automated machinery to bond to solve the above problems and reduce the design difficulty of the automated machinery.

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0019] The utility model discloses a packaging box sheet and a highly sealed packaging box thereof, and the specific structure is described in detail as follows:
[0020] As shown in the attached figure of the instruction manual Figure 1 As shown, a packaging box sheet includes a bottom plate sheet 1, and the bottom plate sheet 1 is a hexagonal bottom plate sheet 1 or an octagonal bottom plate sheet 1. This embodiment takes an octagonal bottom plate sheet 1 as an example. Each side of the bottom plate sheet 1 can be folded and provided with its own side sheet 2; as shown in the accompanying drawings of the specification Figure 2 and Figure 3 As shown, after the side sheets 2 on each side of the bottom plate sheet 1 are folded, the adjacent side edges of the adjacent side sheets 2 are adapted to fit and overlap.
[0021] The side sheets 2 include the same number of transition sheets 3 and box edge sheets 4. In this embodiment, there are four transition sheets 3 and four box edge sheets 4. The transition sheets 3 are distributed at the top corners of the packaging box, and there is a box edge sheet 4 between each adjacent transition sheet 3.
[0022] As shown in the attached figure of the instruction manual Figure 1 and Figure 2 As shown, each of the transition sheets 3 can be folded to have a bonding platform 5 on the outside, and each of the box edge sheets 4 can be folded to have bonding corners 6 on both ends of the outside. The two bonding corners 6 on the box edge sheets 4 on both sides of the bonding platform 5 and close to the bonding platform 5 are adapted to the bonding platform 5.
[0023] In order to ensure that the four top corners of the packaging box are rounded, the outer edges of the bonding platform 5 and the outer edges of the bonding corners 6 are both adapted arc-shaped edges 7 .
[0024] In order to increase the structural strength of the four convex side cuttings on the top of the packaging box, the outermost side of the box edge sheet 4 can also be folded to provide a folding bottom sheet 8. After folding, the folding bottom sheet 8 can make the four convex side cuttings on the top of the packaging box double-layer thickened, thereby improving the strength.
[0025] In order to facilitate the folding of the sheet structures, the foldable positions between the sheets are provided with dotted cut lines 9.
[0026] A highly airtight packaging box, wherein the four transition sheets 3 and the four box edge sheets 4 are bonded through the bonding platform 5 and the bonding corner 6 to form a packaging box profile, and a layer of sealing film 10 is fixedly attached to the inner surface of the packaging box profile, so that the inside of the packaging box can be sealed and leak-proof.
[0027] In summary:
[0028] The bonding between adjacent transition sheets 3 and box edge sheets 4 is achieved through bonding platforms 5 and bonding corners 6, and the bonding platforms 5 and bonding corners 6 are located at the top surface after folding, and the bonding positions of the bonding platforms 5 and bonding corners 6 are horizontal and exposed, thereby realizing vertical pressure bonding by automated machinery, which also greatly reduces the design difficulty of automated machinery.
