Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic products, in particular to an anti-theft lunch box. Background Art
[0002] With the rise of the food delivery industry, the use of bento boxes has become increasingly common. However, with the current large number of delivery drivers, food delivery platforms lack effective control, leading to cases of individual delivery drivers stealing customers' food. Once food is delivered from the merchant, the integrity of the food is entirely at the disposal of the delivery driver, making it difficult for merchants to monitor their behavior.
[0003] In response to the problem of food theft, some lunch box manufacturers are developing anti-theft lunch boxes. When the food is packaged in the lunch box, it will leave traces if it is opened, so that customers can know in time that the food has been stolen. However, the common anti-theft lunch boxes on the market are difficult to balance anti-theft performance, difficulty in unpacking, and cost. For example, in order to save costs, the design of some anti-theft lunch boxes is only to stick a note on one side of the lunch box, and the lunch box can still be easily opened from the other side. If the lunch box is stuck with notes on all four sides, the workload is large and the difficulty of unpacking is also very great. Therefore, it is necessary to develop an anti-theft lunch box that is low in price, has good anti-theft performance, and is easy for customers to unpack. Utility Model Content
[0004] Based on this, the utility model provides an anti-theft lunch box, in which anti-theft lock buckles are inserted at both ends of the bottom box and the front cover, thereby locking the front cover to the bottom box, and the front cover can be removed by breaking the anti-theft lock buckles. The unpacking is simple, and it is easy to identify whether it has been unpacked. The utility model has a low price, good anti-theft performance, and is convenient for customers to unpack.
[0005] A theft-proof lunch box, comprising:
[0006] The bottom box is provided with a storage slot for loading food; both ends of the bottom box are provided with a first lock hole; the first lock hole passes through the bottom box in a vertical direction;
[0007] The cover is connected to the bottom box; the cover is arranged on the receiving slot; the outer sides of both ends of the cover are provided with bosses; each boss is provided with a second lock hole; the second lock hole passes through the cover in the direction and is arranged opposite to the first lock hole; and
[0008] An anti-theft lock buckle is arranged between the bottom box and the surface cover; the anti-theft lock buckle includes: an arrow, a pull rod connecting the arrow, and a limit head connected to the pull rod; the arrow passes through the first lock hole and the second lock hole in sequence from top to bottom and is then clamped at the bottom of the bottom box; the pull rod is located between the bottom box and the surface cover; the limit head is located outside the surface cover and abuts the top surface of the boss; a breaking portion for connecting the pull rod is provided at the bottom of the limit head.
[0009] When serving the anti-theft lunch box, the food is placed in the storage slot of the bottom box, and the cover is then placed on the storage slot, thereby protecting the food. Next, the anti-theft lock buckle is inserted into the first and second lock holes in sequence, with the arrow pointing downward, until the limit head abuts against the boss of the cover and cannot be inserted further. At this time, the barb of the arrow passes through the second lock hole and abuts against the bottom of the bottom box, preventing it from retreating. This locks the bottom box and the cover together, achieving the purpose of anti-theft. When it is necessary to remove the cover, the limit head of the anti-theft lock buckle is grasped and bent sideways, forcing the broken part at the bottom of the limit head to be destroyed. The limit head is then separated from the pull rod, and the cover can be unsealed. Disassembly is easy, and restoration after unsealing is difficult. This design can be implemented by only making minor modifications to the traditional lunch box, and has a simple structure and low cost. Through the above design, anti-theft locks are inserted into both ends of the bottom box and the front cover, so that the front cover is locked on the bottom box, and the front cover can be removed by breaking the anti-theft locks. The unpacking is simple and it is easy to identify whether it has been unpacked. It has low price, good anti-theft performance, and is convenient for customers to unpack.
[0010] In one embodiment, the outer periphery of the bottom box is provided with a raised edge, and the boss is located on the inner side of the edge. The edge can surround the anti-theft lock buckle on the inner side to prevent the anti-theft lock buckle from breaking due to accidental contact or collision with external objects.
[0011] In one embodiment, the top height of the limit head is lower than the height of the surrounding edge. This design can further reduce the risk of the anti-theft lock buckle breaking due to accidental touch or collision with external objects.
[0012] In one embodiment, the first and second keyholes have a vertical cross-section that is wide at the top and narrow at the bottom, forming an inverted trapezoidal structure. This inverted trapezoidal structure allows the arrow to pass through the first and second keyholes smoothly and prevents the arrow from moving backward after passing through the first and second keyholes.
[0013] In one embodiment, the cover is a transparent cover, which allows customers to observe the product intuitively.
[0014] In one embodiment, the front end of the arrow is provided with an arc surface. This design can reduce the risk of the arrow getting stuck and difficult to enter when docking with the first lock hole and the second lock hole.
[0015] In one embodiment, the bottoms of both sides of the limit head are provided with rounded corners that abut the top surface of the boss. This design allows the bottom of the limit head to form a fulcrum with the boss when the customer bends the limit head, thereby reducing the difficulty of breaking the anti-theft lock buckle.

[0039] like Figures 1 to 12 As shown, it is an anti-theft lunch box 100 according to an embodiment of the present invention.
[0040] like Figure 1 and Figure 4 As shown, the anti-theft lunch box 100 includes: a base box 10, a cover 20 connected to the base box 10, and an anti-theft lock 30 provided between the base box 10 and the cover 20. The base box 10 is used to store food, the cover 20 is used to cover the base box 10 to protect the food, and the anti-theft lock 30 is used to lock the base box 10 and the cover 20 together.
[0041] Below, combined Figures 1 to 12 , the above-mentioned anti-theft lunch box 100 is further explained.
[0042] like Figure 7 and Figure 8 As shown, the bottom box 10 is provided with a storage slot 11 for loading food. The two ends of the bottom box 10 are respectively provided with a first locking hole 12. The first locking hole 12 passes through the bottom box 10 in the vertical direction.
[0043] like Figure 1 and Figure 6 As shown, the cover 20 is placed on the storage slot 11. Figure 9 and Figure 10 As shown, the outer sides of the cover 20 are provided with bosses 21, each with a second lock hole 22. The second lock hole 22 extends through the cover 20 in the direction of the center and is located opposite the first lock hole 12. In this embodiment, the cover 20 is transparent. This transparent cover allows customers to directly observe the product.
[0044] like Figure 11 and Figure 12 As shown, the anti-theft lock 30 includes: an arrow 31, a pull rod 32 connected to the arrow 31, and a limit head 33 connected to the pull rod 32. Figure 3 and Figure 5 As shown, the arrow 31 passes through the first lock hole 12 and the second lock hole 22 from top to bottom and is then clamped at the bottom of the bottom box 10. The pull rod 32 is located between the bottom box 10 and the cover 20. The width of the pull rod 32 matches the first lock hole 12 and the second lock hole 22. The limit head 33 is located outside the cover 20 and abuts against the top surface of the boss 21. The width of the limit head 33 is greater than the width of the first lock hole 12 and the second lock hole 22. Therefore, the limit head 33 cannot penetrate the first lock hole 12 and the second lock hole 22. Figure 11 As shown, a breaking portion 331 for connecting to the pull rod 32 is provided at the bottom of the limiting head 33 .
[0045] Brief description of working principle:
[0046] like Figure 6 As shown, when serving food, the food is placed in the receiving groove 11 of the bottom box 10, and then the cover 20 is placed on the receiving groove 11 to protect the food. Figure 2 and Figure 3 As shown, the anti-theft lock buckle 30 is placed vertically, and then the arrow 31 is inserted downward into the first lock hole 12 and the second lock hole 22 in sequence until the limit head 33 abuts against the boss 21 of the surface cover 20 and cannot be inserted further. At this time, the hook part of the arrow 31 passes through the second lock hole 22 and abuts against the bottom of the bottom box 10 and cannot retreat, thereby locking the bottom box 10 and the surface cover 20 together to achieve the purpose of anti-theft. When it is necessary to remove the front cover 20, the user grasps the stopper 33 of the anti-theft lock 30 and bends it sideways, forcing the broken portion 331 at the bottom of the stopper 33 to be broken. The stopper 33 then separates from the pull rod 32, and the front cover 20 can be removed. Disassembly is easy (for example, the customer can grasp a stopper 33 of the anti-theft lock 30 with each hand and bend it back and forth 1-2 times to separate the stopper 33 of the anti-theft lock 30 from the pull rod 32, and then the front cover 20 can be removed). After removal, the front cover 20 is difficult to restore. This design only requires minor modifications to the traditional lunch box, is simple in structure, and is low in cost.
[0047] Considering that the limit head 33 of the anti-theft lock 30 is a design that is easily broken when subjected to lateral force, further improvements can be made to reduce the risk of the lunch box breaking due to collision with external objects during the delivery process. Figure 6As shown, the outer periphery of the bottom box 10 is provided with a raised edge 13, and the boss 21 is located on the inner side of the edge 13. The edge 13 can surround the anti-theft lock 30 on the inner side to prevent the anti-theft lock 30 from breaking due to accidental touch or collision with external objects.
[0048] Furthermore, if Figure 2 As shown, the top height of the limit head 33 is lower than the height of the surrounding edge 13. This design can further reduce the risk of the anti-theft lock buckle 30 being broken due to accidental touch or collision with external objects.
[0049] Furthermore, considering that the anti-theft lock buckle 30 needs to continuously pass through the first and second lock holes 12, 22, and to improve the smoothness of the insertion of the arrow 31, in other embodiments, the first and second lock holes 12, 22 have a vertical cross-section that is wide at the top and narrow at the bottom. The inverted trapezoidal structure of the first and second lock holes 12, 22 allows the arrow 31 to pass through the first and second lock holes 12, 22 smoothly and makes it difficult for the arrow 31 to retreat after passing through the first and second lock holes 12, 22.
[0050] like Figure 11 As shown, in this embodiment, the front end of the arrow 31 is provided with an arc surface 311. This design can reduce the risk of the arrow 31 being stuck and difficult to enter when docking with the first lock hole 12 and the second lock hole 22, and can also achieve the purpose of improving the smoothness of the insertion of the arrow 31.
[0051] like Figure 11 and Figure 12 As shown, in this embodiment, the bottoms of both sides of the limit head 33 are provided with rounded corners 332 that abut the top surface of the boss 21. This design allows the bottom of the limit head 33 to form a fulcrum between the boss 21 when the customer bends the limit head 33, thereby reducing the difficulty of breaking the anti-theft lock buckle 30.
[0052] The above-mentioned anti-theft lunch box 100 has anti-theft locks 30 inserted at both ends of the base box 10 and the cover 20, so that the cover 20 is locked on the base box 10, and the cover 20 can be removed by breaking the anti-theft locks 30. The unpacking is simple and it is easy to identify whether it has been unpacked. It is low in price, has good anti-theft performance, and is convenient for customers to unpack.
[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
