[0031] As Figure 2-6 shown, this embodiment provides a packaging box, which includes a box body 1. The box body 1 has an opening 2. One side of the opening 2 extends a covering piece 31. The covering piece 31 can be bent towards the opening 2 and cover the opening 2. The outer edge of the covering piece 31 further extends an inserting piece 32. The inserting piece 32 can be further bent and inserted into the box body 1. On the side of the opening 2 opposite to the covering piece 31, a sealing piece 4 extends. An easy-tearing line 5 is formed between the sealing piece 4 and the edge of the opening 2. After the sealing piece 4 is bent, it fits against the covering piece 31. The fitting method can be selected but is not limited to heat sealing, glue sealing or double-sided tape sticking. The easy-tearing line 5 can be selected but is not limited to a discontinuous virtual sealing line, that is, it is formed as an incomplete sealing line with multiple breaks; as Figure 7 shown, when in use, the easy-tearing line 5 is damaged, and then the product in the box body 1 can be taken out.

[0032] In this way, compared with the prior art, the packaging box provided by this embodiment can be well sealed and packaged by the fitting of the sealing piece 4 and the covering piece 31, so that the packaging box is not easily accidentally opened during transportation and circulation, etc. Moreover, there is no need to additionally set an outer plastic packaging, which can save certain costs; and, in this embodiment, an easy-tearing line 5 is provided on the sealing piece 4. When in use, the easy-tearing line 5 can be easily damaged to take out the product in the box body 1; after taking out, the covering piece 31 and the inserting piece 32 can be inserted into the opening 2 again to prevent the remaining product in the box body 1 from falling out.

[0033] As a preferred solution of this embodiment, an easy-to-tear assisting portion 41 is further formed on the sealing piece 4, a notch 21 matching with the easy-to-tear assisting portion 41 is formed on the edge of the opening 2, and a joint of the easy-to-tear assisting portion 41 and the notch 21 forms a part of the easy-to-tear line 5, and the body of the sealing piece 4 and both sides of the notch 21 form the other parts of the easy-to-tear line 5; an inner edge of the easy-to-tear assisting portion 41 is formed with a bending line 42, so that the body of the sealing piece 4 can be bent to fit with the covering piece 31. By pulling the easy-to-tear assisting portion 41, it is more convenient to take out the product in the box body 1.

[0034] The easy-to-tear assisting portion 41 is in a sheet shape, and preferably in a lug structure. An inner end of the lug structure forms the bending line 42, and an outer edge of the lug structure is semi-circular or arc-shaped, which is convenient for operation. The notch 21 is also formed as a semi-circular surface notch or an arc surface notch. Of course, in other embodiments, the lug structure can also be in other shapes such as square, triangular or irregular.

[0035] As a preferred solution of this embodiment, first side pieces 61 and second side pieces 62 further extend from the other two side edges of the opening 2. The first side pieces 61 and the second side pieces 62 are symmetrically arranged. After being bent, the first side pieces 61 and the second side pieces 62 cover a part of the opening 2, and can play a certain limiting role on the inserted piece 32 and the covering piece 31 after being bent and covered, so that the covering piece 31 can basically cover the opening 2 in parallel and will not fall into the opening 2. More preferably, in this embodiment, a folding line 33 is formed at the joint of the covering piece 31 and the inserted piece 32, and movable sockets 34 are formed at both ends of the folding line 33. Limiting protrusions 63 extend from one side of the first side pieces 61 and the second side pieces 62 close to the movable sockets 34 when the covering piece 31 covers. After the inserted piece 32 is inserted, the limiting protrusions 63 can move along the inner surface of the inserted piece 32 and then snap into the corresponding movable sockets 34, so as to limit the inserted piece 32, and thus the box body 1 can be prevented from being accidentally opened.

[0036] As Figure 2 shown, the box body 1 is preferably a cubic container, the opening 2 is a rectangular opening, the covering piece 31 and the inserted piece 32 are formed on the front side of the rectangular opening, the sealing piece 4 is formed on the rear side, and the first side pieces 61 and the second side pieces 62 are respectively formed on the left and right sides.

[0037] The box body 1 can be used to place orally dissolving film packaging sheets (not shown in the figure). The orally dissolving film packaging sheets include orally dissolving films and bag bodies packaging the orally dissolving films, and the two form a sheet-like whole. One or more of the orally dissolving film packaging sheets can be placed in the box body 1. After taking out, the inserted piece 32 and the covering piece 31 are closed and inserted. When taking out again, the inserted piece 32 and the covering piece 31 are opened by pulling the easy-to-tear assisting portion 41, which is convenient for taking out. Of course, in other embodiments, the box body 1 can also be used to place other products.

[0038] Figure 1 The exploded view of the packaging box of this embodiment is shown. The middle main body part of the box body 1 includes five vertical surfaces 7. The five vertical surfaces 7 are sequentially enclosed, and the last vertical surface 7 is attached to the first vertical surface 7, finally forming a square frame; the top of the box body 1 includes the first side piece 61, the covering piece 31 and the inserting piece 32, the second side piece 62 and the sealing piece 4, which are sequentially enclosed and distributed in the circumferential direction. The first side piece 61 and the second side piece 62 are first bent to cover a part of the opening 2 at the top, then the covering piece 31 and the inserting piece 32 are bent and inserted into the opening 2 at the top, and then the sealing piece 4 is bent and attached to the outer surface of the covering piece 31. Figure 1 The dotted line part in [description] is the tear line 5. When in use, the tear line 5 is damaged and then the tear assisting part 41 is pulled to open the box body 1 to take out the product; the bottom and top structures of the box body 1 are basically symmetrical, the difference being that no tear line needs to be provided at the sealing piece at the bottom.

[0039] As can be seen from the above, a packaging box provided in this embodiment is provided with a sealing piece attached to the covering piece, which can well seal the box body, and a tear line is also provided on the sealing piece, making it very convenient to open the box body and take out the product.
