Figures 1-5 As shown, it includes an aviation injection-molded lunch box, an aviation injection-molded lunch cover, four locking sleeves, and four connecting locks.

[0023] like Figure 1 and Figure 2The aviation injection-molded meal box can store airline food for carrying. The aviation injection-molded meal box includes a meal box shell 3, a meal box frame 31, a plug-in sleeve hole 311, a meal area divider 32, and a food storage cavity 33. The meal box shell 3 and the meal area divider 32 are integrally injection molded from polypropylene (PP) material. The meal box frame 31 is integrally connected to the upper periphery of the meal box shell 3, which acts as a barrier when it is connected to the aviation injection-molded meal lid. Four plug-in sleeve holes 311 are symmetrically opened on the inner side of both ends of the meal box frame 31, which facilitates corresponding installation with the outside. The meal area divider 32 is integrally connected to the inside of the meal box shell 3, which can serve as a divider. A food storage cavity 33 is opened between the meal box shell 3 and the meal area divider 32, which is convenient for placing airline food for carrying. The shape of the lower outer side of the lunch box shell 3 corresponds to the inner area of ​​the stacked cavity 11, and they can be nested and stacked.

[0024] The aviation injection-molded lunch cover is fitted onto the upper inner side of the aviation injection-molded lunch box, effectively covering and shielding it to prevent dust from entering and food from spilling. The aviation injection-molded lunch cover includes a lid shell 1, a bottom sleeve plate 12, and a transparent panel 2. The lid shell 1 and the bottom sleeve plate 12 are integrally injection molded from polypropylene (PP) material. The bottom sleeve plate 12 is integrally connected to the lower middle of the lid shell 1, and the integral connection is not easy to break or be damaged. The upper inner side of the lid shell 1 and the bottom sleeve plate 12 has a stacking cavity 11, which makes it convenient for the lunch box shells 3 to be stacked. The transparent panel 2 is fixedly connected to the inner side of the stacking cavity 11 inside the bottom sleeve plate 12. The transparent material of the transparent panel 2 makes it easy for people to observe. The lid shell 1 is fitted onto the upper inner side of the lunch box shell 3 via the bottom sleeve plate 12, which can effectively fit and seal it. The outer closed sides of the lid shell 1 and the lunch box frame 31 are aligned so that they do not obstruct use.

[0025] Example 2 This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-5 As shown, to further better realize the present invention, the following arrangement is specifically adopted: four locking sleeves are symmetrically and integrally connected at the four corners of the lower end of the aviation injection molded lunch cover. The integral connection is not easy to break or be damaged. The locking sleeves can pass through the aviation injection molded lunch box for assembly. The locking sleeves include a sleeve insert 52. The sleeve insert 52 is integrally connected to the lunch cover shell 1, which is convenient for injection molding. The lower end of the sleeve insert 52 is integrally connected to a semi-circular sleeve head 5. The rounded head of the semi-circular sleeve head 5 is convenient for sleeve connection. The periphery of the sleeve insert 52 is integrally connected to a compression protrusion ring 51. The protruding part of the compression protrusion ring 51 can effectively compress and lock. The semi-circular sleeve 5, the extrusion protrusion ring 51, and the socket insert 52 can pass through the insertion sleeve hole 311 of the lunch box frame 31 and can be assembled accordingly.

[0026] The four locking buckles are all fitted onto the four locking buckle posts, making it easy to lock them together. After being fitted, the locking buckles can be located at the bottom of the aviation injection molded lunch box, which can effectively block the view. The locking buckles include the locking sleeve 4, and the lower end of the locking sleeve 4 is integrally connected to the pull ring 41, which is easy for people to hold and press and pull. The inner side of the locking sleeve 4 and the pull ring 41 is provided with a locking sleeve cavity 42 for easy fitting and installation. The locking sleeve 4 and the snap ring 41 are respectively fitted onto the locking insert 52 and the extrusion protrusion 51 through the locking sleeve cavity 42, and can be effectively fitted together. The extrusion force of the fitting can stably lock them together.

[0027] Working principle: In use, the airline meals are first placed into the food storage cavity 33 of the meal box shell 3, and the dining area partition 32 is used to achieve partitioning and isolation. Then, the meal cover shell 1 is aligned with the inner side of the upper end of the meal box shell 3 through the bottom sleeve plate 12, so that the meal cover shell 1 is aligned with the outer side of the meal box frame 31. At the same time, the four locking sleeves 52, the compression protrusion ring 51 and the semi-circular sleeve head 5 are respectively passed through the insertion sleeve hole 311 of the meal box frame 31.

[0028] Pick up the locking buckle from the bottom of the lunch box, hold the locking sleeve 4 through the buckle ring 41, align the locking sleeve cavity 42 with the semi-circular sleeve head 5 and put it on, push the locking sleeve 4 forcefully so that it passes over the extrusion protrusion ring 51 and is locked on the locking post 52, thus completing the secure locking of the lid and the lunch box and preventing food from spilling out.

[0029] When multiple cutlery pieces need to be stacked, simply align the lower end of the next cutlery's container shell 3 with the stacking cavity 11 of the previous cutlery's lid and nest them directly, saving a significant amount of space. To open the lid, grasp the latching ring 41 and pull it outwards to disengage the locking sleeve 4 from the pressing protrusion ring 51, then you can open the lid and take out the food.

[0030] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
