Technical Field
[0001] The utility model belongs to the technical field of lunch box processing, and in particular relates to a highly sealed disposable lunch box. Background Art
[0002] With the development of the economy and the accelerated pace of life, ordering takeout has become an indispensable way of dining in people's lives. Therefore, the sales volume of disposable lunch boxes for holding takeout meals is also increasing. At the same time, disposable lunch boxes have gradually changed from the original easily damaged foam lunch boxes to plastic lunch boxes that are easy to carry, not easy to damage, low in toxicity, high in melting point and environmentally friendly. However, due to its poor overall sealing performance, the existing disposable lunch boxes are prone to soup leakage when used, especially when holding food with soup. At the same time, when packing the existing disposable lunch boxes, since there is no storage position for disposable tableware and seasoning packets in the lunch boxes, the disposable tableware and seasoning packets are mostly placed directly in the packaging bag, which is easy to be lost and has poor safety and hygiene. Therefore, in order to solve the above problems, it is necessary to develop a high-sealing disposable lunch box with stable and reasonable structural design and good use effect. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a high-sealing disposable lunch box with a stable and reasonable structural design and good use effect.

[0005] The convex block a and the convex block b are both arc-shaped structures.
[0006] The front end and the rear end of the lower surface of the box body are both transversely provided with grooves, and the front end and the rear end of the upper surface of the top cover are both transversely fixed with blocks that match the groove structure.
[0007] The middle position of the upper surface of the middle pressure cover is recessed downward to form a tableware placement groove.
[0008] An information note placement frame is fixedly arranged in the middle of the front end surface of the box body.
[0009] The beneficial effects of the utility model are as follows: the utility model provides a connecting guard edge, a convex block a, a limiting guard edge and a convex block b. When in use, the convex block a cooperates with the limiting cavity b, and the convex block b cooperates with the limiting cavity a. Pressure can be applied to achieve the matching sleeve connection between the connecting guard edge and the limiting guard edge, thereby completing the limiting connection between the box body, the middle pressure cover and the box cover; the sealing groove, the middle pressure cover, the rubber sealing ring and the annular pressure block are provided. When in use, the annular pressure block on the lower surface of the box cover is used to limit the connection between the box body, the middle pressure cover and the box cover. The pressure applied by the pressing block to the middle pressure cover can cause the rubber sealing ring on the lower surface of the middle pressure cover to be compressed and deformed, so that its lower surface is in close contact with the upper surface of the connecting guard edge and the bottom surface of the sealing groove. This structure can increase the sealing effect of the utility model when it is used; at the same time, by providing a tableware placement groove, disposable tableware and seasoning packets such as chili and vinegar can be placed in the tableware placement groove to avoid loss while improving safety and hygiene; in general, the utility model has the advantages of stable and reasonable structural design and good use effect.

DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings.
[0019] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a highly sealed disposable lunch box comprises a box body 1, an intermediate gland 2 and a box cover 3. The box body 1 is a square groove structure with an opening at the upper end, and a connecting guard 4 is integrally connected to the upper end thereof. A plurality of annular sealing grooves 41 are evenly arranged on the upper surface of the connecting guard 4, and a plurality of protrusions a42 are fixedly sleeved on the outer side, and a limited position cavity a is formed between two adjacent protrusions a42; the intermediate gland 2 is located above the connecting guard 4, and a rubber sealing ring 21 is fixedly arranged on the outer surface of the lower surface thereof, and the rubber sealing ring 21 is located just above the connecting guard edge 4; the box cover 3 is located above the middle pressure cover 2, and is composed of a top cover 31 and a limiting guard edge 32 integrally connected to the bottom of the top cover 31, and an annular pressure block 33 is fixedly provided at a position corresponding to the rubber sealing ring 21 on the lower surface of the top cover 31, and a plurality of annular protrusions b34 are evenly fixedly provided on the lower end of the inner surface of the limiting guard edge 32 from top to bottom, and the protrusions b34 have the same structure as the limiting cavity a, and a limiting cavity b matched with the structure of the protrusion a42 is formed between two adjacent protrusions b34.
[0020] The protrusion a42 and the protrusion b34 are both arc-shaped structures. The arc-shaped structure can increase the smoothness of the connection between the protrusion a42 and the limiting cavity b, and the protrusion b34 and the limiting cavity a; the front end and the rear end of the lower surface of the box body 1 are both transversely provided with grooves 11, and the front end and the rear end of the upper surface of the top cover 31 are both transversely fixed with blocks 35 that match the groove 11 structure. The cooperation between the groove 11 and the block 35 can facilitate the vertical stacking of multiple lunch boxes; the middle position of the upper surface of the middle pressure cover 2 is recessed downward to form a tableware placement groove 22, and the tableware placement groove 22 can be used to place disposable tableware and seasoning packets such as chili and vinegar to avoid loss, while improving safety and hygiene; an information note placement frame 12 is fixedly provided in the middle of the front end surface of the box body 1, and the information note placement frame 12 can be used to facilitate the unified storage of information notes on food in the lunch box.
[0021] When the utility model is in use, first, the food to be packaged is placed inside the box body 1, and then the middle pressure cover 2 is placed just above the box body 1, and the rubber sealing ring 21 on the lower surface of the middle pressure cover 2 is brought into contact with the upper surface of the connecting guard edge 4, and then the box cover 3 is placed above the middle pressure cover 2. At this time, by utilizing the cooperation between the protrusion a42 and the limiting cavity b, and the cooperation between the protrusion b34 and the limiting cavity a, downward pressure can be applied to the box cover 3, thereby achieving the matching sleeve connection between the connecting guard edge 4 and the limiting guard edge 32, and then completing the limiting connection between the box body 1, the middle pressure cover 2 and the box cover 3; at the same time, in the process of utilizing external pressure to complete the limiting connection between the box body 1, the middle pressure cover 2 and the box cover 3, the annular pressure block 33 on the lower surface of the box cover 3 can also produce downward extrusion on the middle pressure cover 2. The force is exerted, and then through the action of this extrusion force, the rubber sealing ring 21 on the lower surface of the middle pressure cover 2 is compressed and deformed, so that the lower surface of the rubber sealing ring 21 is in close contact with the bottom surface of the sealing groove 41. The utility model adopts this structure to increase the sealing effect when it is used; and the utility model provides a tableware placement groove 22, which can be used to place disposable tableware and seasoning packets such as peppers and vinegar, so as to avoid loss while improving safety and hygiene; by providing a groove 11 and a card block 35, the cooperation of the groove 11 and the card block 35 can facilitate the vertical stacking of multiple lunch boxes; by providing an information note placement frame 12, the information notes of food in the lunch box can be stored uniformly; in general, the utility model has the advantages of stable and reasonable structural design and good use effect.
