[0021] For further clarity of explanation, various aspects and advantages of the embodiments disclosed in the present application will become apparent in the following description or can be understood through the practice of the embodiments disclosed in the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The accompanying drawings are used to provide further understanding of the present application and constitute a part of the specification. Together with the following specific embodiments, they are used to explain the invention but do not constitute a limitation to the invention.

[0023] Figure 1 This is a schematic diagram of the box cardboard provided in Example 1 of the present application. DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] Example 1

[0026] Reference Figure 1 The box paperboard 100 shown is formed into a rectangular parallelepiped by bending along the folding lines on the box paperboard. The rectangular parallelepiped is the paper self-sealing box provided in this embodiment.

[0027] The paper self-sealing box comprises:

[0028] A plurality of covers, each of which forms the aforementioned rectangular parallelepiped, one face of which is an opening face, and an inner cover 1 located in the inner layer and an outer cover 2 located in the outer layer are provided on the opening face;

[0029] The first side 21 of the outer cover 2 of the opening surface is connected to the other covers, the second side 22 of the outer cover 2 is parallel to the first side, and the third side 23 and the fourth side 24 of the outer cover 2 are perpendicular to the first side 21 and the second side 22 of the outer cover 2; the first side of the inner cover 1 of the opening surface is connected to the other covers, the second side of the inner cover 1 is parallel to the first side, and the third side and the fourth side of the inner cover 1 are perpendicular to the first side and the second side of the inner cover 1;

[0030] In the overlapping area of ​​the outer cover 2 and the inner cover 1, a first tear strip 3 and a second tear strip 4 are provided on the outer cover 2 or in the cover material, and the first tear strip 3 and the second tear strip 4 are less likely to be torn than the cover; in one embodiment, the cover is made of paper, and the first tear strip 3 and the second tear strip 4 are made of plastic material;

[0031] The first tear strip 3 and the second tear strip 4 are at different distances from the second edge 21 of the outer cover of the opening surface and do not intersect with each other; the first tear strip 3 is close to the side of the second edge 22 of the outer cover of the opening surface;

[0032] An adhesive layer 5 is provided on one side of the first tear strip 3 close to the second edge 22 of the outer cover of the opening surface and between the first tear strip 3 and the second tear strip 4. A protective layer is provided outside the adhesive layer 5. After the protective layer is torn off, the adhesive layer 5 is exposed.

[0033] When used for the first time, after tearing off the protective layer on the adhesive strip on the second side 22 of the outer cover closer to the opening surface, the adhesive layer adheres the outer cover 2 to the inner cover 1, completing the closure of the paper self-sealing box. When it is necessary to unpack, the first tear strip 3 is torn off, and the outer cover 2 and the inner cover 1 are separated, that is, the paper self-sealing box is opened. When it is necessary to seal the box again, after tearing off the protective layer on the adhesive strips of the first tear strip 3 and the second tear strip 4, the adhesive layer adheres the outer cover 2 to the inner cover 1 again, completing the closure of the paper self-sealing box again. When it is necessary to unpack, the second tear strip 4 is torn off, and the outer cover 2 and the inner cover 1 are separated, that is, the paper self-sealing box is opened. It can be seen that the paper self-sealing box provided in this embodiment does not need to be glued with tape and can be sealed and used twice. No tools are required when unpacking, and it is convenient to use.

[0034] Moreover, in this embodiment, several of the covers are connected into one piece. Figure 1The box paperboard 100 shown is formed into a rectangular parallelepiped by bending along the folding line on the box paperboard. The rectangular parallelepiped is the paper self-sealing box mentioned above. The paper self-sealing box can be unfolded into a rectangular parallelepiped before and after use. Figure 1 The box paperboard 100 shown is convenient for storage; multiple box paperboards 11 can be folded for storage, thus reducing the storage space occupied when not in use.

[0035] In this embodiment, an implementation method of a specific shape of the outer cover 2 is provided:

[0036] A first group of left notches A1 is set on the third side 23 of the outer cover of the opening surface, and the first group of left notches A1 includes two slender strip-shaped notches, and the outer cover between the two slender strip-shaped notches is the left first opening tongue 25; a first group of right notches B1 is set on the fourth side 24 of the outer cover of the opening surface, and the first group of right notches B1 includes two slender strip-shaped notches, and the outer cover between the two slender strip-shaped notches is the right first opening tongue 26; the first tear strip 3 is set on the cover between the left first opening tongue 25 and the right first opening tongue 26 or in the cover material.

[0037] A second group of left notches A2 is set on the third side 23 of the outer cover of the opening surface, and the second group of left notches A2 includes two slender strip-shaped notches, and the outer cover between the two slender strip-shaped notches is the left second opening tongue 27; a second group of right notches B2 is set on the fourth side 24 of the outer cover of the opening surface, and the second group of right notches B2 includes two slender strip-shaped notches, and the outer cover between the two slender strip-shaped notches is the right second opening tongue 28; the second tear strip 4 is set on the cover between the left second opening tongue 27 and the right second opening tongue 28 or in the cover material.

[0038] The peninsula-shaped opening tongues make it easier for the user to pinch the first tear strip 3 and the second tear strip in this embodiment, making it easier for the user to apply force to pull off the first tear strip 3 (or the second tear strip 4). In this embodiment, the opening tongues are provided at both ends of the first tear strip 3 (or the second tear strip 4). If the first tear strip 3 (or the second tear strip 4) is torn during tearing, the user can pinch the opening tongue on the other side and continue tearing from the other side, ultimately completing the separation of the outer cover 2 and the inner cover 1.

[0039] In one embodiment, the outer cover 2 is intermittently provided with elongated holes 29 inside the elongated notch. The length of each elongated hole 29 is parallel to the first edge 21 of the outer cover. The elongated holes 29 can be formed by cutting through the cardboard of the box with a blade on the end. The provision of the elongated holes 29 makes it easier to tear the cardboard, without requiring an excessively long opening tongue, which would otherwise reduce the strength of the outer cover 2.

[0040] In one embodiment, the width of the protective layer is greater than the width of the adhesive layer 5. The user pinches the portion of the protective layer that exceeds the adhesive layer to make it easier to tear off the protective layer.

[0041] In one embodiment, one long side of the protective layer coincides with one long side of the adhesive layer, and the other long side of the protective layer is wavy or zigzag. Based on the above embodiment, this method is more conducive to tearing off the protective layer.
