Description

Technical Field

[0001] This utility model relates to the field of packaging and storage container technology, specifically to a lockable anti-theft cardboard box. Background Technology

[0002] Cardboard boxes, as a common and important form of packaging, are widely used in the transportation and storage of various products. With the rapid development of e-commerce and the increasingly frequent circulation of goods, the demand for cardboard boxes has not only increased significantly in quantity but also placed higher demands on quality and functionality. Cardboard boxes made from corrugated cardboard have become the preferred packaging material for many businesses due to their advantages such as low cost, ease of processing, and recyclability.

[0003] Currently, traditional cardboard boxes on the market are mostly sealed with tape. Feedback from actual users indicates that this sealing method has many inconveniences. When unpacking, customers often find it difficult to quickly locate the tape, especially when various labels are affixed to the outside of the box, further obscuring the tape's position. Because it's difficult to find the starting point of the tape, customers have to spend a lot of time and effort searching. When attempting to tear open the box, it's difficult to tear the tightly adhered tape with just their hands; usually, a knife or other tools are needed to cut the tape. This process is not only cumbersome and laborious, increasing the difficulty and time cost of unpacking, but also, when using tools, the sticky residue from the tape tends to adhere to the tools, affecting their subsequent use and being difficult to clean, causing significant inconvenience to customers and reducing the user experience. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a lockable anti-theft cardboard box, comprising a box body folded from corrugated cardboard, including a bottom surface, a top surface, a bottom surface, an inner folded surface, and four side surfaces. The four side surfaces are adjacent to each other and connected by fold lines. The top and bottom surfaces are provided with a primary locking structure, which includes a locking tongue fixed to the end of the top surface away from the side surface, with folding flaps fixed to both ends of the locking tongue. A locking groove is provided on the end of the bottom surface near the side surface corresponding to the locking tongue. When the bottom and top surfaces are folded sequentially to the top of the box, the locking tongue can be inserted into the locking groove after the folding flaps are folded. Both the top and bottom surface sidewalls are provided with a secondary locking structure, which includes a connecting strip fixed to the side wall of the bottom surface. The side wall of the bottom surface also has a ring for inserting the connecting strip. A secondary anti-theft strip is pasted on the top surface. When the bottom and top surfaces are folded sequentially to the top of the box, the secondary anti-theft strip can be pasted onto the connecting strip.

[0005] Furthermore, a level one anti-theft strip is affixed to the lock tongue.

[0006] Furthermore, multiple perforations are provided on the top surface near the end of the latch to form a tear strip, and a pull ring is fixed to the outer wall of the tear strip.

[0007] Further, the two side walls of the upper top surface are fixed with protruding parts, when the lower top surface and the upper top surface are folded on the top of the box in turn, the protruding parts are between the inserting strip and the inserting ring, so that when the inserting strip is inserted in the inserting ring, a gap is left between the inserting strip and the lower top surface, to facilitate the extracting of the inserting strip when opening.

[0008] Further, the box is pasted with L-shaped reinforcing strips at four side folding positions.

[0009] The utility model has the advantages as follows:

[0010] 1. The lock buckle type anti-theft paper box discards the traditional adhesive tape pasting sealing method, adopts the design of combination of one-level locking structure and two-level locking structure, and only needs to break the one-level anti-theft strip and the two-level anti-theft strip, pull the ring to pull the tear strip, and make the lock tongue separate from the lock groove when the customer unpacks the box, so that the paper box can be easily opened, the adhesive tape pasting position does not need to be found, and tools such as knives are not needed, the unpacking process is greatly simplified, the unpacking time and energy are saved, and the convenience of unpacking of users is improved.

[0011] 2. Since the adhesive tape sealing is no longer relied on, the problem of adhesive tape of tools in the unpacking process is completely avoided. After the customer unpacks the box, it is not necessary to worry about the pollution of tools by glue, the cleaning and normal use of tools are ensured, cumbersome work of cleaning the adhesive stain is avoided, and a more refreshing and convenient unpacking experience is provided for the customer.

[0012] 3. The traditional adhesive tape sealing is extremely easy to cause damage to the paper box in the tearing process, influences the secondary utilization value of the paper box, the lock buckle structure of the paper box can maximize the integrity of the paper box when normally opened, the paper box is convenient for the customer to properly save or secondarily utilize, conforms to the environmental protection concept, and reduces the packaging cost.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] A type of interlocking anti-theft cardboard box, such as Figure 1 and Figure 2 As shown, the box includes a box body 1, which is folded from corrugated cardboard. It includes a bottom surface, an upper top surface 101, a lower top surface 102, an inner folded surface 103, and four sides. The four sides are adjacent to each other and connected by fold lines. The upper top surface 101 and the lower top surface 102 are provided with a primary locking structure. The primary locking structure includes a latch 201 fixed at the end of the upper top surface 101 away from the side. Folding flaps 202 are fixed at both ends of the latch 201. A lock groove 203 is opened at the end of the lower top surface 102 near the side corresponding to the latch 201. When the lower top surface 102 and the upper top surface 101 are folded sequentially to the top of the box body 1, the latch 201 can be inserted into the lock groove 203 after the folding flaps 202 are folded. A primary anti-theft strip 204 is pasted on the latch 201. Multiple punch holes are opened at the end of the upper top surface 101 near the latch 201 to form a tear strip 4. A pull ring is fixed to the outer wall of the tear strip 4.

[0020] The case body 1 is formed by folding corrugated cardboard. A locking tongue 201, folding flap 202, and locking groove 203 create a primary locking mechanism. A primary anti-theft strip 204 is used for security, while a tear strip 4 and pull ring facilitate opening. The locking design enhances the stability and anti-theft properties of the case body 1, and the tear strip 4 and pull ring provide a convenient opening method, avoiding the difficulty of opening traditional tape seals.

[0021] like Figure 1 andFigure 2 As shown, in this embodiment, both the upper top surface 101 and the lower top surface 102 are provided with a two-level locking structure. The two-level locking structure includes a connector strip 301 fixed to the side wall of the lower top surface 102. The side wall of the lower top surface 102 is also fixed with a ring 302 for inserting the connector strip 301. A two-level anti-theft strip 303 is pasted on the upper top surface 101. When the lower top surface 102 and the upper top surface 101 are folded to the top of the box 1 in sequence, the two-level anti-theft strip 303 can be stuck to the connector strip 301. The two side walls of the upper top surface 101 are fixed with protrusions 5. When the lower top surface 102 and the upper top surface 101 are folded to the top of the box 1 in sequence, the protrusions 5 are located between the connector strip 301 and the ring 302, so that when the connector strip 301 is inserted into the ring 302, there is a gap between the connector strip 301 and the lower top surface 102, so as to facilitate the removal of the connector strip 301 when it is opened.

[0022] The dual-locking structure further enhances the anti-theft performance, reduces the risk of unauthorized opening, and the protrusion 5 design ensures that the connector 301 can be smoothly pulled out during normal opening. The insertion ring 302 restricts the movement of the connector 301, thus balancing anti-theft and convenient opening.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, L-shaped reinforcing strips 6 are attached to the four folded sides of the carton 1. This enhances the structural strength of the carton 1, disperses stress at the folds, reduces deformation and damage caused by external pressure or collision, extends the service life of the carton, and better protects the contents.

[0024] The working principle of this utility model is as follows:

[0025] First, place the goods to be packaged into the box 1, which consists of a bottom and four sides. After folding the inner fold 103 to cover the goods, fold the bottom top surface 102 along the fold line so that it covers the top part of the box 1. Next, fold the top surface 101 so that it covers the bottom top surface 102. During the folding process, fold the flap 202 into the inside of the latch 201. The latch 201 is accurately inserted into the lock groove 203 of the bottom top surface 102. Under the action of the flap 202's rebound, the latch 201 can abut against the lock groove 203. Then, attach the first-level anti-theft strip 204 to the side of the box 1 to achieve a preliminary locking and anti-theft function.

[0026] When the upper top surface 101 is folded, the connector strip 301 on the lower top surface 102 also gradually approaches the upper top surface 101 as the folding action is performed. When the upper and lower top surfaces 102 are completely folded into place, the protrusion 5 on the side wall of the upper top surface 101 is located between the connector strip 301 and the insert ring 302. The connector strip 301 covers the protrusion 5 and is inserted into the corresponding insert ring 302 on the upper top surface 101. The protrusion 5 leaves a gap between the connector strip 301 and the lower top surface 102 to facilitate the removal of the connector strip 301 when opening. Then, the secondary anti-theft strip 303 is glued to the side of the box body 1 to further enhance the locking and anti-theft effect.

[0027] When someone attempts to illegally open the carton, whether by trying to open it through the latch 201 or by pulling it out through the connector 301, the primary security strip 204 or the secondary security strip 303 will be damaged. Damage to the primary security strip 204 and the secondary security strip 303 will leave obvious marks, such as tears or damage to the adhesive surface, thus warning that the goods may have been illegally accessed.

[0028] When opening the carton, first tear open the primary security strip 204 and the secondary security strip 303, then pull the tear strip 4 using the pull ring. Since the tear strip 4 has multiple perforations, it will tear along these perforations during the pulling process, facilitating the disengagement of the locking tongue 201 from the locking groove 203. This ultimately separates the upper top surface 101 and the lower top surface 102, allowing the carton to be opened smoothly.

[0029] 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, and all such changes and modifications fall within the scope of the claimed utility model.
