Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a snap-on packaging box. Background Technology

[0002] Existing packaging boxes have several design and usage issues. On one hand, the boxes lack locking mechanisms, resulting in poor anti-theft functionality. On the other hand, existing locking mechanisms are overly complex. While they offer some anti-theft protection, they are cumbersome to operate, inefficient, and inconvenient for users to open. Furthermore, these locking mechanisms are often located on the outside of the box, leaving tear-off slits on the outer surface, which affects the box's appearance and results in poor packaging effectiveness. Utility Model Content

[0003] To address the shortcomings of the prior art, this utility model provides a snap-lock packaging box that can be locked to prevent theft.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A snap-fit ​​packaging box includes a box body with a top opening. The top opening has a locking structure, which includes an inner cover, an outer cover, a slot, and a tongue. The inner cover and the outer cover are respectively connected to the opposite edges of the top opening. The outer cover is connected to the tongue on the opposite edge of the top opening. The slot is U-shaped, having a horizontal portion and a vertical portion connected to both ends of the horizontal portion. The horizontal portion is located on the fold line connecting the inner cover and the top opening. The vertical portion extends into the inner cover. The tongue includes a tongue body connected to the edge of the outer cover and folded ears on both sides of the tongue body. After the locking structure closes the top opening, the inner cover is located inside, and the outer cover covers the outer side of the inner cover. The folded ears fold inward to form a U-shape with the tongue body and are inserted into the box body through the slot, where they spring back and lock onto the inner surface of the inner cover.

[0006] This technical solution features a locking structure at the top opening of the box. When packaging items, the folded lug of the tongue folds inward to form a U-shape with the tongue body, allowing it to be inserted into the box through the slot. The box material springs back and locks onto the inner surface of the inner lid, thus achieving a lock. The box cannot be opened from the top opening without damaging the locking structure, thus providing an anti-theft function. Furthermore, the locking structure is located inside the box, resulting in a clean box surface without tearing or cutting, and excellent packaging performance.

[0007] In this specific embodiment of the invention, the end of the vertical portion of the slot is inclined inward towards the inner side of the inner cover. This prevents the folded ear from sliding out of the slot after insertion, resulting in a better locking effect.

[0008] In a specific embodiment of this utility model, the locking structure further includes a first tear-out portion, which is formed by a first perforation line provided on the plate surface where the box body and the inner cover are connected, and both ends of the first perforation line are connected to the transverse portion of the slot.

[0009] In a specific embodiment of this utility model, the locking structure further includes a second tear-off portion, which is composed of two symmetrical second perforation lines, one end of which is connected to the end of the vertical portion of the slot, and the other end of which extends to the two side edges of the inner cover.

[0010] The locking structure, by setting a first tear-off part and a second tear-off part, allows the locking structure to be easily broken through the first tear-off part and the second tear-off part when it is necessary to open the packaging box, making the packaging box easy to open.

[0011] In a specific embodiment of this utility model, the area enclosed by the first perforation line and the transverse portion of the slot is semi-circular.

[0012] In a specific embodiment of this utility model, the second perforation line is a double wavy line.

[0013] In a specific embodiment of this utility model, the box body has a bottom opening, and the bottom opening is provided with the aforementioned locking structure. By providing the same locking structure at the bottom opening of the box body, it is easier to open the packaging box from the bottom opening, resulting in better usability.

[0014] The beneficial effects of this invention are as follows: First, the packaging box can be locked and theft-proof by setting a locking structure at the top opening. Second, the locking structure is provided with a first tear-off part and a second tear-off part, so that the locking structure can be easily broken through the tear-off part when opening the packaging box, making it convenient to open. Third, the packaging box can have the same locking structure at the bottom opening, so the packaging box has a double locking function, supporting opening from both ends, making it more convenient to use. At the same time, the locking structure is located inside the box body, the box surface is clean and beautiful, without tear lines or cuts, and the packaging effect is better.

[0024] like Figure 1 The snap-on packaging box of this utility model includes a box body 100, the box body having a top opening 101, and the top opening 101 being provided with a locking structure.

[0025] The locking structure includes an inner cover 102, an outer cover 103, a slot 200, and a tongue 300. The inner cover 102 and the outer cover 103 are respectively connected to the edges of opposite sides of the top opening 101. The slot 200 is U-shaped and includes a horizontal part 201 and a vertical part 202 connected to both ends of the horizontal part 201. The horizontal part 201 is located on the fold line connecting the inner cover 102 and the top opening 101. The vertical part 202 extends into the inner cover 102. The tongue 300 includes a tongue body 301 and folded ears 302 located on both sides of the tongue body 301. The tongue 300 is connected to the outer cover 103 through the tongue body 301 and the edge of the other side of the top opening 101.

[0026] Combination Figure 2 As shown, the locking structure can close the top opening 101 of the box 100. When the top opening 101 is closed, the inner cover 102 is located on the inside, and the outer cover 103 covers the outside of the inner cover 102. The folding lug 302 folds inward and forms a U-shape with the tongue body 301, then inserts into the box 100 through the slot 200 and springs back to lock onto the inner surface of the inner cover 102 inside the box 100. In this way, the top opening 101 of the box 100 is in a closed and locked state. Without breaking the locking structure, the packaging box cannot be opened from the top opening 101.

[0027] To enhance the locking effect of the locking structure, as the vertical part 202 of the slot 200 extends into the inner cover 102, its end is inclined towards the inside of the inner cover 102, that is, towards the center of the inner cover 102. In this way, after the tongue 300 is inserted into the box 100 through the slot 200, the folded ears 302 on both sides of the tongue body 301 are easily stuck inside the inner cover 102, so the folded ears 302 can no longer slide out of the slot 200, resulting in a better locking effect.

[0028] Combination Figure 3 As shown, to facilitate opening the packaging box from the top opening 101, the locking structure also includes a first tear-off portion and a second tear-off portion. The first tear-off portion is formed by a first perforation line 400 provided on the plate surface where the box body 100 connects to the inner cover 102. Both ends of the first perforation line 400 are connected to the horizontal portion of the slot 200, forming a semi-enclosed area. In this embodiment, the two ends of the first perforation line are respectively connected to the two ends of the horizontal portion of the slot 200 and form a semi-circle with the area enclosed by the horizontal portion of the slot 200. The second tear-off portion is formed by two symmetrical second perforation lines 500, one end of which is connected to the end of the vertical portion of the slot 200, and the other end extends towards the two side edges of the inner cover 200. In this embodiment, the second perforation lines 500 are double wavy lines.

[0029] In this invention, the packaging box also has an opening at the bottom, which is provided with a locking structure of the same type.

[0030] Using the above technical solution, after the packaging box is completed, because the top opening 101 of the box body 100 is equipped with a locking structure, the packaging box cannot be opened from the top opening 101 without damaging the locking structure, thus the packaging box has an anti-theft function. At this time, if one wants to open the packaging box from the top opening 101 to take out the items inside, simply press the first tear-off section inside the box body 100 with a finger; the first tear-off section will be torn open. Then, lifting upwards will tear the second tear-off section as well. Figure 4 As shown, the locking structure of the top opening 101 is broken, and the top opening 101 is opened, allowing the contents of the packaging box to be removed. Similarly, when the bottom opening of the box 100 also has the same locking structure, if you want to open the packaging box from the bottom opening, you can break the locking structure set in the bottom opening in the same way, thus opening the bottom opening of the packaging box as well.

[0031] As can be seen from the detailed description above, the snap-lock packaging box of this utility model firstly, by setting a locking structure at the top opening 101 of the box body 100, after the top opening 101 is closed, the tongue 300 connected to the outer cover 103 is folded into a U-shape and inserted into the box body 100 through the slot 200. Utilizing the self-rebound property of the box body 100, it locks itself onto the inner surface of the inner cover 102, thus preventing the box from being opened from the top opening 101 without damaging the locking structure, thereby providing an anti-theft function. Secondly, the locking structure is provided with a first tear-off part and a second tear-off part, which can be easily broken through the locking structure, making it easy to open. Thirdly, the bottom opening of the box body 100 can also be provided with the same locking structure, facilitating opening the box from the bottom and improving its usability. Finally, the locking structure is located inside the box body 100, resulting in a clean and aesthetically pleasing surface without tear lines, leading to good packaging performance.

[0032] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
