Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to an induction snap-on sealed anti-theft food packaging box. Background Technology

[0002] Food packaging boxes are packaging carriers that take into account both food preservation and safety protection. They are widely used in categories such as snacks, baked goods, and ready-made meals. They are mostly made of food-grade PE / PET material and are equipped with snap-on, heat-press, or spiral sealing structures. They can isolate air, moisture, and microorganisms, and extend the shelf life of food. At present, they have become an important packaging choice for the food industry to ensure quality and enhance consumer trust.

[0003] Existing technology publication number CN211033642U discloses a disposable anti-theft food packaging box. It features a box body and an unlocking plate. A mounting groove is formed on the outer wall of the second connecting plate near the first connecting plate. A locking rod is movably inserted into the outer wall of the first connecting plate near the second connecting plate, extending through the first connecting plate into the mounting groove. A locking device is provided between the locking rod and the mounting groove. An unlocking device is provided on the unlocking plate. The advantages are: the locking rod is inserted between the first and second connecting plates, and two locking rods connect them. The locking rods are located in two locking holes, making them difficult for consumers to touch, thus preventing the box from being opened by hand. Two movable rods are symmetrically mounted on the unlocking plate. Fixing blocks on the two movable rods are inserted into the locking holes, pushing the two locking rods away from the locking holes, thereby opening the top cover. It is very convenient to use.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist:

[0005] 1. Traditional food packaging boxes have poor locking structure stability, rely on a single fastening method, lack magnetic positioning assistance, and the buckle and slot are prone to misalignment. During transportation, vibration can easily cause them to loosen, leading to seal failure and making the food susceptible to moisture, oxidation, and spoilage.

[0006] 2. Lack of one-time anti-theft labels: Most packaging boxes rely solely on ordinary fasteners or tape seals. After opening, traces can be concealed by re-tapping or re-fastening. Criminals can open and replace inferior contents without authorization. Consumers cannot determine whether food has been tampered with through the packaging, making it easy to purchase spoiled or adulterated products, which harms their health rights and directly impacts consumer safety and market trust. Utility Model Content

[0007] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of poor locking stability, lack of anti-theft identification, resulting in sealing failure, food spoilage and damage to consumer rights. To this end, we propose an induction snap-on sealing anti-theft food packaging box.

[0008] To achieve the above objectives, this application adopts the following technical solution: an induction snap-fit ​​sealed anti-theft food packaging box, including a box body, a box cover on the top of the box body, and locking components installed on both sides of the box body. The box cover includes a cover body, which is located above the opening of the box body. Snap buckles are installed on both sides of the bottom edge of the cover body. Snap buckles have snap feet installed on the bottom side of the snap buckles near the box body. A certain angle is set between the snap feet and the snap buckles, and the snap buckle positions correspond to the locking components.

[0009] Preferably, a sealing groove is installed at the bottom of the cover, corresponding to the opening of the box.

[0010] Preferably, the buckle is provided with an easy-tear strip near the top, and the upper and lower edges of the easy-tear strip are provided with dotted tear lines.

[0011] Preferably, the locking component includes a fixing strip, which is installed on both sides of the box body, and a connecting strip is installed on the top of the fixing strip, with a slot connected to the top of the connecting strip.

[0012] Preferably, the port width of the slot is greater than the width of the latch.

[0013] Preferably, a magnetic suction device is installed on the side of the slot close to the box body, and a magnetic suction strip is provided at the corresponding position on the box body.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention achieves precise locking and enhanced sealing by installing magnetic strips on the slot side close to the box body and at corresponding positions on the box body. The magnetic force automatically aligns the slot with the box body. When the buckle is inserted into the slot, the magnetic strip helps to fix the buckle's position, preventing loosening due to misalignment. During transportation, the magnetic force can offset some of the vibration and impact, preventing the buckle from separating from the slot and ensuring the sealing groove always fits tightly against the top edge of the box body, effectively isolating air, moisture, and microorganisms, extending the food's shelf life. Simultaneously, the magnetic-assisted positioning makes disassembly and assembly easier for consumers, improving usability and solving the problems of poor locking stability and easy seal failure in traditional designs.

[0016] This invention achieves efficient anti-theft identification and consumer trust protection by incorporating a dotted, tear-off strip near the top of the buckle. The dotted, tear-off strip is a one-time design; it cannot be removed without damage when locked. Consumers must tear the strip to open the package, and it cannot be resealed after tearing. This provides a clear indication of whether the packaging has been opened. If the package is opened during transport, the damage to the strip allows consumers to quickly identify the issue and refuse delivery, avoiding the purchase of food with substituted contents. This structure effectively prevents unscrupulous merchants from unauthorized opening and replacement, providing consumers with clear anti-counterfeiting evidence, enhancing consumer confidence, making anti-theft identification more accurate and convenient, protecting food quality and consumer rights, and improving product market competitiveness.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Reference Figure 1As shown, this utility model provides a technical solution: an induction snap-fit ​​sealed anti-theft food packaging box, including: a box body 1, a box cover 2 provided on the top of the box body 1, and locking components 3 fixedly installed on both sides of the box body 1 by adhesive. The locking components 3 are used to fix the box body 1 and the box cover 2, so that they are more tightly sealed.

[0026] Reference Figure 2 As shown in this embodiment: the box cover 2 includes a cover body 21, which is located above the opening of the box body 1. A sealing groove 22 is installed at the bottom of the cover body 21 by adhesive. The top edge of the box body 1 is embedded in the sealing groove 22 for sealing. Buckles 23 are fixedly installed on both sides of the bottom of the cover body 21. Buckle feet 24 are fixedly installed on the bottom side of the buckles 23 near the box body 1. Buckle feet 24 and buckles 23 maintain a certain angle. Buckle feet 24 have a certain flexibility and can bend to fit the buckles 23. An easy-tear strip 25 is provided near the top of the buckles 23. The upper and lower edges of the easy-tear strip 25 are set as dotted tear marks. The box cover 2 can be separated from the buckle feet 24 by tearing the easy-tear strip 25 through the tear marks. That is, the box cover 2 is released from the locked state by tearing through the tear marks. Once torn, it cannot be restored, thus performing anti-theft identification.

[0027] Reference Figures 3-5 As shown in this embodiment: the locking component 3 includes a fixing strip 31, which is glued to both sides of the box body 1. A connecting strip 32 is fixedly installed on the top of the fixing strip 31, and a slot 33 is fixedly connected to the top of the connecting strip 32. The cooperation between the connecting strip 32 and the fixing strip 31 forms a movable connection structure. When the slot 33 is not locked, the connecting strip 32 is bent due to its redundant length, allowing it to move flexibly with the slot 33 without detaching from the box body 1. When the slot 33 is locked upwards, the connecting strip 32 is straightened, which does not affect the locking operation and firmly fixes the slot 33 to the side of the box body 1, preventing the slot 33 from falling off or being lost. The port width of 33 is slightly larger than the width of the buckle 23. When the buckle 23 is inserted vertically into the slot 33, the buckle foot 24 at the bottom of the buckle 23 can bend inward through the slot 33. After the buckle foot 24 passes through the slot 33, it returns to the angled open state and abuts against the bottom of the slot 33, thereby fixing the buckle 23 so that it cannot move upward, thus locking the box cover 2. The slot 33 is fixed with a magnetic component by adhesive on the side close to the box body 1. The box body 1 is provided with a magnetic strip 34 at the corresponding position. The slot 33 can slide up and down along the magnetic strip 34 through the magnetic component, so that the slot 33 can slide upward through the magnetic strip 34 and lock with the buckle 23.

[0028] Working principle: In the sealing and initial locking stage of packaged food, the staff first puts the food into the box body 1, and then closes the box lid 2. The pre-set sealing groove 22 at the bottom of the box lid 2 will fit into the top edge of the box body 1, forming the first sealing barrier through physical adhesion, blocking the intrusion of external air, moisture and microorganisms, laying the foundation for food preservation. Because the connecting strip 32 of the locking component 3 is bent when not locked, the staff can first slide the slots 33 on both sides of the box body 1 upward along the magnetic strip 34. The magnetic parts on the side of the slot 33 and the magnetic strip 34 attract each other, which not only ensures the stability during the sliding process, but also helps the slots 33 to accurately align. The buckles 23 on both sides of the lid 2 are aligned. After the slot 33 and the buckle 23 are aligned, the buckle 23 is vertically inserted into the slot 33. During the insertion process, the buckle foot 24 at the bottom of the buckle 23 is flexible and will be squeezed inward by the inner wall of the slot 33 to pass through the slot 33 smoothly. When the buckle foot 24 has completely passed through the slot 33, it will return to the initial angled open state and firmly abut against the bottom of the slot 33. The mechanical limit prevents the buckle 23 from moving upward, and finally locks the lid 2 and the box body 1. At this time, the connecting strip 32 is also straightened as the slot 33 moves upward, further fixing the slot 33 to the side of the box body 1 to prevent it from falling off and being lost.

[0029] During the consumer opening and anti-theft identification stage, consumers need to open the packaging through the easy-tear strip 25 above the buckle 23. The dotted tear lines on the top and bottom of the easy-tear strip 25 are weak points. Consumers can tear the easy-tear strip 25 completely by tearing along the tear lines. The easy-tear strip 25, buckle 23, and buckle foot 24 are integrated into one design. After tearing, the box lid 2 will separate from the buckle foot 24, releasing the buckle foot 24 from the slot 33. At this time, consumers can slide the slot 33 down along the magnetic strip 34 to make the buckle 23 disengage from the slot 33, and then open the box lid 2 to take out the food. Since the easy-tear strip 25 cannot be restored after being torn, if the packaging box is privately opened during transportation or sales, the damage marks of the easy-tear strip 25 will be clearly visible. Consumers can quickly judge whether the food has been tampered with by these marks, realizing anti-theft identification and protecting their own consumer rights.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
