[0032] Further, the shell assembly further comprises a handle 3 and a buckle 16, the handle 3 is in the shape of "n", the handle 3 provides a more stable gripping point, making the overall meal box more convenient to move and transport, cylindrical protrusions are symmetrically fixedly arranged on the inner and outer walls of the two vertical shafts of the handle 3, and the cylindrical protrusions are coaxially and rotatably connected with the circular holes formed on the fixed blocks 2, the handle 3 can be pushed upwards when not in use, so that it is parallel to the side surface of the aluminium foil box shell 1 and does not occupy space, the buckle 16 is fixedly connected to the two inner side walls of the short axis of the groove formed on the aluminium foil box shell 1, and the buckle 16 is in the shape of "L".

[0033] Further, the containing groove assembly comprises a containing box 7 and a clamping groove 14, the containing box 7 is provided with an isolation layer, which can effectively isolate the influence of the external environment on the food in the box, including temperature, humidity and odor, the existence of this layer further enhances the sealing performance of the aluminium foil meal box, ensuring the freshness and taste of the food during storage and transportation, the containing box 7 is also a rectangular body with rounded corners, and the shape and size of the containing box 7 correspond to the groove formed on the surface of the aluminium foil box shell 1 and can be embedded therein, a groove is formed on the upper surface of the containing box 7, and the four corners of the groove are also rounded, two groups of stepped holes are symmetrically formed on the two sides of the groove on the surface of the containing box 7, and a clamping groove 14 is symmetrically formed on the two outer side walls of the short axis of the containing box 7, and the clamping groove 14 is in the shape of inverted "L".

[0034] Further, the accommodating groove assembly further comprises a handle 10 and a limiting block 15. The handle 10 is in the shape of a Chinese character "door" and is slidably connected to a stepped hole formed on the surface of the accommodating box 7. The handle 10 is arranged to make it easier to take out the food, thereby reducing the risk of slipping or collision when the hand contacts the food box, ensuring the safety and smoothness of the food taking process. The limiting block 15 is fixedly arranged on the end surface of the handle 10 in the stepped hole. The diameter of the limiting block 15 is slightly larger than the diameter of the two vertical shafts of the handle 10. When the handle 10 slides in the stepped hole, the stepped hole will clamp the limiting block 15, thereby fixing the handle 10.

[0035] Further, the size and shape of the buckle 16 correspond to the size and shape of the clamping groove 14. When the accommodating box 7 is nested, the long side of the buckle 16 is elastically deformed by the extrusion of the edge of the accommodating box 7. When the clamping groove 14 and the buckle 16 are aligned, the buckle 16 returns to its original shape, thereby clamping the accommodating box 7. The elastic deformation force of the buckle 16 is not large, so the accommodating box 7 can be easily taken out of the aluminum foil box shell 1 with a little force. The precise cooperation and locking mechanism of the buckle 16 and the clamping groove 14 ensure that the aluminum foil box shell 1 and the accommodating box 7 can be firmly combined when assembled.

[0036] Further, the lid assembly comprises a lid 4 and a pull ring 5. The lid 4 is also a rectangular body with rounded corners. A recess is formed on the bottom surface of the lid 4. The pull ring 5 is fixedly arranged on the surface of the lid 4. The pull ring 5 makes it easier to open the lid 4 without the need for additional tools or effort, and the lid 4 can be quickly removed.

[0037] Further, the lid assembly further comprises a clamping block 11, a spring 12 and a cylindrical support block 13. A through hole is formed in the middle of the inner wall of the recess formed on the bottom surface of the lid 4. The cylindrical support block 13 is fixedly arranged on the surface of the clamping block 11. The spring 12 is fixedly connected to the outer periphery of the cylindrical support block 13 on the surface of the clamping block 11. The other end of the spring 12 is fixedly connected to the bottom surface of the through hole formed on the recess. When the lid 4 is nested, the clamping block 11 is extruded by the fixed rubber ring 6 and exerts pressure on the spring 12. When the clamping block 11 completely passes through the fixed rubber ring 6, the spring 12 returns to its original shape, thereby driving the clamping block 11 to clamp the aluminum foil box shell 1, so as to form a sealed space inside the aluminum foil box shell 1. This not only prevents leakage of food when tilted or moved, but also effectively blocks the intrusion of external air and bacteria, thereby better maintaining the freshness and safety of the food. The spring 12 has good elasticity, and the lid 4 can be separated from the aluminum foil box shell 1 with a little force.

[0038] Furthermore, the partition assembly includes a long partition 8 and a short partition 9. Both the long partition 8 and the short partition 9 are "I"-shaped plates. The two vertical plates of the long partition 8 are tightly fitted with the short axis of the groove in the receiving box 7, and the two vertical plates of the short partition 9 are tightly fitted with the long axis of the groove in the receiving box 7. If the receiving box 7 is to be divided into sections, the short partition 9 can be placed inside. The short partition 9 can slide freely inside the receiving box 7 to adjust the partition area. The long partition 8 and the short partition 9 both have grooves on their surfaces. If it is to be divided into multiple sections, the long partition 8 can be snapped on, thus dividing it into four sections.

[0039] Working principle: When not using handle 3, push it upwards to make it parallel to the side of the aluminum foil box shell 1 without taking up space. Hold the handle 10 with both hands, and the handle 10 will slide in the stepped hole. The stepped hole will lock the limiting block 15, fixing the handle 10. At this time, place the receiving box 7 into the aluminum foil box shell 1. When the receiving box 7 is nested, the long side of the buckle 16 will undergo elastic deformation due to the pressure of the edge of the receiving box 7. When the locking groove 14 is aligned with the buckle 16, the buckle 16 will return to its original shape, locking the receiving box 7. The elastic deformation force of the buckle 16 is not large, and the receiving box 7 can be removed from the aluminum foil box shell 1 with a little force. After the aluminum foil box shell 1 and the receiving box 7 are successfully nested, press the handle 10 downwards to make its horizontal axis The lid 4 fits snugly against the surface of the container 7 without taking up much space. Hold the pull ring 5 and place the lid 4 on the outer shell 1 of the aluminum foil box. When the lid 4 is nested, the snap-fit ​​block 11 is squeezed by the fixing rubber ring 6 and applies pressure to the spring 12. The spring 12 is compressed. When the snap-fit ​​block 11 has completely passed the fixing rubber ring 6, the spring 12 returns to its original shape, driving the snap-fit ​​block 11 forward to lock the outer shell 1 of the aluminum foil box. The spring 12 has good elasticity, and the lid 4 can be separated from the outer shell 1 of the aluminum foil box with a little force. If you want to divide the container 7 into sections, you can put in the short partition 9. The short partition 9 can slide freely in the container 7 to adjust the partition area. If you want to divide it into multiple sections, you can snap on the long partition 8, so that it can be divided into four sections.
