[0023] Currently, fast food boxes are widely used by various fast food companies, restaurants, and canteens when delivering meals, providing convenience for users. There are many types of fast food boxes available.
[0024] With the rapid development of the food delivery industry and the increasing workload and fast pace of life, food delivery services have flourished. However, delivery drivers often encounter bumpy journeys during delivery, which can cause spills of soup or other liquids from the food containers. Furthermore, existing food containers typically have a lid that snaps directly onto the container's edge, making them easy to open and allowing others to easily replace the food inside.
[0025] Reference Figure 1 This application provides an anti-theft lunch box, including a box body 100 and a box lid 200.
[0026] The lid 200 has an annular groove 221. The box body 100 is assembled on the lid 200. The box body 100 has multiple locking blocks 300. The locking blocks 300 are used to lock in the annular groove 221. The thickness of the locking blocks 300 is less than the depth of the annular groove 221. Each locking block 300 is connected to the box body 100 through a flexible connecting plate 310. The flexible connecting plate 310 has at least two spaced tear seams 311. Each tear seam 311 extends along the width direction of the flexible connecting plate 320 to both sides of the flexible connecting plate 320.
[0027] After the lid 200 is placed on the box body 100, the latch 300 is folded up and latched into the annular groove 221. The latch 300 will be embedded inside the annular groove 221, thereby locking the lid 200 and the box body 100. Since the thickness of the latch 300 is less than the depth of the annular groove 221, it is difficult for others to pry the latch 300 out of the annular groove 221 by hand, thus playing a role in preventing theft. Moreover, this connection method between the latch 300 and the annular groove 221 can connect the lid 200 and the box body 100 more tightly, effectively preventing the soup inside the food container from spilling out. When the customer who ordered the food receives the food container, he can tear the flexible connecting plate 310 by hand along the two tear seams 311. At this time, the latch 300 is still retained in the annular groove 221, while the box body 100 and the lid 200 have been separated.
[0028] In some embodiments, the card block 300 is connected to the edge of the opening side of the box body 100 via a flexible connecting plate 310, and the annular groove 221 is formed near the edge of the box cover 200.
[0029] Specifically, in this application, the material used for the flexible connecting plate 310 is the same as that used for the lunch box. The flexible connecting plate 310 connects the card block 300 to the edge of the opening side of the box body 100. The annular groove 221 is opened near the edge of the box cover 200, so that the card block 300 and the annular groove 221 are close to each other, which facilitates the connection between the card block 300 and the annular groove 221.
[0030] In some embodiments, the individual card blocks 300 are distributed around the perimeter of the housing 100.
[0031] Specifically, each of the front, back, left, and right sides of the box body 100 is connected to a card block 300 via a flexible connecting plate 310.
[0032] In some embodiments, the flexible connector plate 310 is provided with two tear seams 311, one of which is a spacer hole structure and the other is a groove structure.
[0033] To facilitate the tearing of the flexible connecting plate 310 by the customer, in some embodiments, the flexible connecting plate 310 has a protrusion 312 on its side, located between two tear seams 311. When the customer tears the flexible connecting plate 310 by hand, they can grasp the protrusion 312 to tear the flexible connecting plate 310 between the two tear seams 311.
[0034] In some embodiments, the lid 200 is provided with an outwardly extending connecting ear 212. This allows the customer to easily grasp the connecting ear 212 and remove the lid 200 from the box body 100.
[0035] To improve the load-bearing capacity of the lunchbox in this application, in some embodiments, the lid 200 includes a lid body 220 and a load-bearing plate 210. The load-bearing plate 210 protrudes from the center of the lid body 220, and a downwardly bent load-bearing portion 211 is provided around the load-bearing plate 210. The load-bearing portion 211 has a wavy pleated structure surrounding the load-bearing plate 210, and the load-bearing portion 211 is connected to the lid body 220. The wavy pleated structure can strengthen the connection between the load-bearing plate 210 and the lid body 220, greatly improving the load-bearing capacity of the load-bearing plate 210.
[0036] In some embodiments, the two ends of the locking block 300 are chamfered. This eliminates any leverage points on the sides of the locking block 300, further preventing others from removing the locking block 300 from the annular groove 221.
[0037] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0038] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
