Description

Technical Field

[0001] This application belongs to the field of packaging and printing technology, specifically relating to an anti-theft packaging box made of die-cut cardboard folded together. Background Technology

[0002] Paper packaging boxes are widely used in the retail packaging of various commodities such as food, pharmaceuticals, cosmetics, electronic products, and gifts due to their advantages such as low cost, environmental friendliness and recyclability, ease of processing and molding, and ease of printing and decoration. To enhance user experience and product reusability, many packaging boxes on the market are designed with reusable opening and closing mechanisms. One very common structure involves a tongue and corresponding slot on the lid or seal of the box; the box is closed by inserting the tongue into the slot. After the initial opening, consumers can usually close the box again using the same method, thus providing some protection for the contents, dust prevention, or ease of storage.

[0003] However, this convenient resealable design presents a significant security risk: poor theft prevention. This deficiency is particularly pronounced in open-shelf retail environments (such as supermarkets, department stores, and electronics stores). Specifically, malicious individuals can easily and carefully pull out the latch, open the box, and remove or replace the high-value items inside (such as expensive cosmetics or snacks) without damaging the overall structure. They can then reseal the empty box by inserting the latch back into the opening. Because the entire process requires no tearing of the box, breaking the seal, or cutting the packaging, relying solely on the box's own opening and closing mechanism, the resealed box appears almost identical to a brand-new, unopened item. Whether retail staff are performing routine inventory checks or consumers are selecting goods, it is difficult to visually determine whether the product has been opened and its contents are missing or have been switched.

[0004] Currently, some manufacturers use disposable tamper-evident stickers or labels to seal the opening of packaging boxes to address this issue. While this method can serve as a warning and prevent tampering to some extent, it increases production costs, complicates the process (requiring manual or automated labeling), and carries the risk that some stickers can still be technically peeled off and reapplied without leaving any noticeable trace. Utility Model Content

[0005] In order to solve the problems mentioned above, the purpose of this utility model is to provide an anti-theft packaging box that is difficult to open without damaging the box body.

[0006] Therefore, this utility model provides an anti-theft packaging box, which is formed by die-cutting and folding a piece of cardboard. The packaging box includes a first box top wall and a box lid that can be inserted and fixed to the first box top wall. The first box top wall is provided with an insertion opening, and the box lid is provided with an insertion tongue. The insertion tongue is provided with a left fold line and a right fold line that are folded in the front-back direction. The left fold line and the right fold line are parallel to each other. The insertion tongue includes a left bend portion located to the left of the left fold line, a right bend portion located to the right of the right fold line, and a middle portion located between the left fold line and the right fold line.

[0022] This application relates to an anti-theft packaging box, which is formed by die-cutting and folding a single sheet of cardboard, serving as a resealable tongue-and-groove type paper packaging box. The packaging box can be closed a second time after being opened.

[0023] like Figure 1 , Figure 4 The diagram shows a schematic of a paper box blank 100 used to manufacture the anti-theft packaging box 200 of this application. The box blank 100 is die-cut from a piece of cardboard, and the anti-theft packaging box 200 will be formed by folding the box blank 100.

[0024] The packaging box blank 100 includes a rectangular box bottom 1 located in the middle, a peripheral side wall 61 connected to the front side of the box bottom 1, a peripheral side wall 62 connected to the rear side of the box bottom 1, a peripheral side wall 63 connected to the left side of the box bottom 1, a peripheral side wall 64 connected to the right side of the box bottom 1, a box lid 2 connected to the front side of the peripheral side wall 61, a first box top wall 3 connected to the rear side of the peripheral side wall 62, a second box top wall 4 connected to the left side of the peripheral side wall 63, a third box top wall 5 connected to the right side of the peripheral side wall 64, a first transition connecting wall 71 located between the peripheral side walls 61 and 63, a second transition connecting wall 72 located between the peripheral side walls 61 and 64, a third transition connecting wall 73 located between the peripheral side walls 63 and 62, and a fourth transition connecting wall 74 located between the peripheral side walls 64 and 62.

[0025] The first transition connecting wall 71 is fan-shaped with a central angle of 90 degrees, and a first fold line 711 extending radially is provided in its center. The second transition connecting wall 72 is fan-shaped with a central angle of 90 degrees, and a second fold line 721 extending radially is provided in its center. The third transition connecting wall 73 is fan-shaped with a central angle of 90 degrees, and a third fold line 731 extending radially is provided in its center. The fourth transition connecting wall 74 is fan-shaped with a central angle of 90 degrees, and a fourth fold line 741 extending radially is provided in its center.

[0026] Combination Figure 2A tongue 8 is provided at the middle position of the front side edge 11 of the lid 1. The tongue 8 intersects with the middle position of the front side edge 11, and a folding crease is provided between them. The tongue 8 is provided with a left fold line 821 and a right fold line 831 that fold in the front-back direction. The left fold line 821 and the right fold line 831 are parallel to each other. The tongue 8 includes a left bend 82 located to the left of the left fold line 821, a right bend 83 located to the right of the right fold line 831, and a middle portion 81 located between the left fold line 821 and the right fold line 831. Both the left bend 82 and the right bend 83 can be bent downward relative to the middle portion 81. A gap 84 is provided between the rear end edge of the left bend 82 and the front side edge 11 of the lid 1, and a gap 85 is provided between the rear end edge of the right bend 83 and the front side edge 11 of the lid 1. As shown in the figure, the middle portion 81 has a first width W1 measured in the left-right direction. The left bend 82 has a third width W3 measured in the left-right direction. The right bend 83 has a fourth width W4 measured in the left-right direction. In this example, the third width W3 and the fourth width W4 are equal and both are less than the first width W1.

[0027] Combination Figure 3 The top wall 2 of the first box is provided with an insertion port 9. The insertion port 9 has a second width W2 measured in the left-right direction. The second width W2 is equal to the first width W1. A U-shaped tear line 91 is also provided on the top wall 2 of the first box. The open end of the U-shaped tear line 91 intersects with the insertion port 9.

[0028] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when the packaging box blank 100 is folded into the packaging box 200, the rectangular box bottom 1 is located at the bottom, and the second box top wall 4 and the third box top wall 5 are located below the first box top wall 3, simultaneously supporting the first box top wall 3 and the box lid 2 from below. The box lid 2 is located above the first box top wall 3, and the two can be inserted and fixed by inserting the tongue 8 into the socket 9. After the insertion is completed, the left bend 82 and the right bend 83 will form "barbs" on the left and right sides of the socket 9 and hook the parts of the first box top wall 3 located on the left and right sides of the socket 9, thereby effectively preventing the box lid 2 from being opened without leaving obvious marks. The user can only open the box lid 2 after tearing part of the first box top wall 3 along the U-shaped tear line 91.

[0029] Furthermore, the first transition connecting wall 71, after being folded along the first fold line 711, abuts against the peripheral side wall 61; the second transition connecting wall 72, after being folded along the second fold line 721, also abuts against the peripheral side wall 61; the third transition connecting wall 73, after being folded along the third fold line 731, abuts against the peripheral side wall 62; and the fourth transition connecting wall 74, after being folded along the fourth fold line 741, also abuts against the peripheral side wall 62. This arrangement effectively prevents the peripheral side wall 63 from being forcibly pulled open to the left when the lid 2 is not opened, and also effectively prevents the peripheral side wall 64 from being forcibly pulled open to the right when the lid 2 is not opened.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope.
