[0002] Disposable meal boxes, as an important carrier of take-out and fast food industry, have been widely used in the field of food packaging. However, the existing disposable meal box cover still has many deficiencies in structural design, especially in terms of theft protection and convenient opening. The traditional meal box cover is usually fixed by a simple edge buckle cooperating with the meal box body. Although it achieves sealing to some extent, this structure cannot effectively prevent the meal box from being opened at will, which leads to the food being easily contaminated or stolen during transportation, affecting the safety of food. In addition, due to the simple design of the buckle structure, the meal box cover often needs a large pulling force to open in the locked state, especially for users with small hand strength, such as children and the elderly, the opening process is particularly inconvenient, which reduces the user experience. At the same time, the edge structure of some disposable meal box covers also has deficiencies in sealing. When the meal box is loaded with liquid or soup food, it is easy to leak during transportation, which leads to food contamination or packaging damage, and cannot meet the high sealing requirement. In addition, in order to meet the batch production, the existing meal box cover often ignores the combination of theft protection and convenient operation in the structural design, which leads to the problem of insufficient theft protection in actual use.

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0027] Unless otherwise defined, technical or scientific terms used in the present application should be understood as having the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms "first", "second", and similar terms used in the present application do not denote any order, quantity, or importance, but are used to distinguish different components. The terms "include" or "contain" and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, without excluding other elements or objects. The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "up", "down", "left", "right", and the like are used only to represent relative positional relationships, which may change accordingly when the absolute positions of the described objects change.

[0028] As Figs. 1-3 , the present embodiment discloses a disposable anti-theft lunch box cover and a disposable lunch box. The disposable anti-theft lunch box cover comprises a cover body, an anti-theft lock catch 1 and an arc-shaped notch 2 are arranged at the corners of the cover body, the anti-theft lock catch 1 is provided with a matching part 101 fixedly connected with the arc-shaped notch 2, and a lock catch part 102 matched with the cover body; the lock catch part 102 is in a hook-shaped structure bent inward, and the hook-shaped structure extends downward from the edge of the cover body to form an arc-shaped bent section. The matching part 101 is provided with a connecting section 103 connected with the cover body along both ends of the edge of the cover body. The disposable lunch box comprises a box body 10, and the box body 10 is matched and used with the disposable anti-theft lunch box cover.

[0029] The mating part 101 is located at the edge where the anti-theft latch 1 connects to the cover, and the mating part 101 consists of spaced-apart serrations. The serrated design of the mating part 101 effectively distributes force to multiple sharp and concave points, rather than concentrating it in a single location. This avoids stress concentration and subsequent fracture propagation, making the structure more stable and controllable under external forces. While this structural design typically creates localized high-stress points at each serration tip, these points are evenly distributed, resulting in a longer structural lifespan. Simultaneously, because the serrated connection part is geometrically designed to create weak points in the material (such as the serration tips or grooves), the required breaking force is relatively small. Consumers can easily break the disposable food container without excessive force. The serrated design of the mating part 101 also ensures a clear fracture path during the breaking process, guaranteeing that the fracture occurs at the designed weak point (i.e., the serration), thus achieving the primary purpose of anti-theft.

[0030] The lid is also provided with tongue handles 3 on both sides for easy opening. The tongue handles 3 extend outward from both sides of the lid and have arc-shaped edges, and are integrally formed with the lid. The tongue handles 3 are designed on both sides of the lid. When the user opens the lid, he applies an upward force to the tongue handles 3. During the separation of the lid from the box, the upward force is transmitted along the edge of the lid. When it is transmitted to the anti-theft latch 1 at the corner, the mating part 101 of the anti-theft latch 1 will gradually begin to separate and break along the path of the arc-shaped notch 2 until the lid is completely separated from the box.

[0031] As another implementation method, such as Figs. 4-5 The position of the tongue handle 3 can also be designed to be integrated with the anti-theft lock 1, extending outward from the mating part 101 of the anti-theft lock 1.

[0032] The inner edge of the lid is provided with a buckle 4 for fastening with the lunchbox body; the inner edge of the lid is also provided with a leak-proof edging 5 to prevent liquid leakage. When the lid is sealed to the lunchbox body, the buckle 4 is fastened to the lunchbox body, and the leak-proof edging 5 is bent towards one side of the box body to better fit the lunchbox body and prevent liquid leakage when the box is filled with liquid.

[0033] The upper surface of the lid is also provided with a planar protrusion 6 and a first recessed layer 7. The planar protrusion 6 and the first recessed layer 7 together form a stacking recessed layer that facilitates the stacking of multiple lids. The lid is also provided with a second recessed layer 8, and several reinforcing ribs 9 are provided between the second recessed layer 8 and the edge of the lid. When disposable anti-theft lunch box lids need to be mass-produced by injection molding, multiple lunch box lids often need to be stacked and packaged. The stacking recessed layer formed by the planar protrusion 6 and the first recessed layer 7 facilitates mass production and allows multiple lunch box lids to be packaged and stacked. At the same time, since disposable lunch box lids are mostly made of plastic, the design of the reinforcing ribs 9 can prevent the lid from increasing the stress on the lid when the lunch box is opened by the user, and prevent the lid from breaking in the middle during opening, which may result in scratches to the user.

[0034] The flat protrusion 6 has ventilation holes to facilitate pressure balance or reduce steam buildup inside the container. When users use disposable food containers for packaging, if the food is fried food such as fried chicken or French fries, it needs to maintain a crispy texture. However, if the lid of the disposable food container is tightly sealed, the high temperature of the fried food inside will cause the water vapor inside the container to liquefy. After the water vapor liquefies, it will soften the fried food that needs to maintain its crispness. When consumers receive the food, the fried food will not maintain its optimal texture, which will reduce the consumer's dining experience. The ventilation holes on the flat protrusion 6 help balance the internal and external air pressure, making it easier to open the lid, and also help to slow down the liquefaction of steam buildup inside the container.

[0035] Working principle

[0036] After the disposable lunch box lid and the box body are engaged, when the user opens it, they apply an upward force to the tongue handle. During the separation of the lid and the box body, the lid will transmit the upward force along the edge of the lid. When it is transmitted to the anti-theft lock at the corner, the engaging part of the anti-theft lock will gradually begin to separate and break along the path of the arc-shaped notch until the lid and the box body are completely separated.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
