[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-Figure 4As shown, a disposable plastic lunch box which is convenient for fixing and stacking includes a box body 1 and a cover plate 2, the cover plate 2 is adapted to the box body 1, a first annular plate 3 is fixedly connected to the top surface of the cover plate 2, a plurality of card slots 4 are opened on the end surface of the first annular plate 3, the card slots 4 are all L-shaped, a second annular plate 5 is fixedly connected to the bottom surface of the box body 1, the diameter of the second annular plate 5 is smaller than the diameter of the first annular plate 3, a plurality of card blocks 6 are fixedly connected to the side wall of the second annular plate 5, the card blocks 6 are adapted to the card slots 4, a sealing assembly is arranged between the edge of the cover plate 2 and the box body 1, and a partition is arranged in the inner cavity of the box body 1.

[0023] like Figure 5 As shown, the sealing assembly includes a sealing ring 7 fixedly connected to the side wall of the box body 1 near the end face, the cross-section of the sealing ring 7 is L-shaped, and a plurality of sealing grooves 8 are opened on the end face of the sealing ring 7. The sealing grooves 8 are L-shaped, and the cover plate 2 is embedded in the sealing grooves 8. The side wall of the cover plate 2 is fixedly connected with a plurality of limit blocks 9 adapted to the sealing grooves 8.

[0024] Among them, the sealing component has the same structure as the first annular plate 3 and the second annular plate 5. In actual production, the materials used can be the same as those used for the box body 1 and the cover plate 2, and can also achieve an integrated molding effect, which is convenient for subsequent processing and production.

[0025] like Figure 5 As shown, the side wall of the box body 1 is fixedly connected with a convex ring 15 on the upper side of the sealing ring 7, and the inner wall of the cover plate 2 is provided with a groove, and the convex ring 15 is adapted to the groove. When the cover plate 2 is covered on the box body 1, after aligning the limit block 9 with the sealing groove 8, it is necessary to press the cover plate 2 down slightly to make the convex ring 15 snap into the snap groove 4 to achieve a primary seal, and the sealing assembly is used to achieve a secondary seal and reinforcement to reduce the probability of leakage.

[0026] like Figure 2 and Figure 5 As shown, the top surface of the cover plate 2 is rotatably connected with a ventilating cover 10, and the ventilating cover 10 and the top surface of the cover plate 2 are respectively provided with ventilating holes 11. The use of the ventilating cover 10 can be selected according to actual needs. When the food in the box body 1 is relatively cool, the ventilating cover 10 can be used to seal the ventilating holes 11. When the food is relatively hot, the ventilating holes 11 on both sides can be connected to facilitate the discharge of hot air in the box body 1 and prevent the box body 1 from expanding.

[0027] like Figure 2 and Figure 4 As shown, the partition includes a disc 12 with an open top, the side wall of the box body 1 is arranged in a stepped shape, the disc 12 is located on the upper side of the step, and a plurality of arc-shaped plates 13 are fixedly connected to the inner wall of the disc 12. A plurality of partitions 14 are fixedly connected to the inner wall of the disc 12. By setting the partition, it is convenient to separate the food, and the user can distinguish and place the food according to its characteristics.

[0028] The working principle of the utility model is as follows: when the box bodies 1 need to be stacked for use, the cover plate 2 is first covered on the box bodies 1 and pressed tightly, and at the same time, the limit block 9 is inserted into the sealing groove 8, and then the cover plate 2 is rotated to drive the limit block 9 to abut against the side wall of the sealing groove 8, which is used to reinforce the cover plate 2 to prevent it from falling off and leaking, and then the sealed box body 1 is placed on the cover plate 2, so that the second annular plate 5 is inserted into the first annular plate 3, and at the same time, the clamping block 6 is inserted into the clamping groove 4, and then the upper box body 1 is rotated to drive the clamping block 6 to abut against the side wall of the clamping groove 4, which is used to stack and fix the box bodies 1 on both sides, ensure the stability between the box bodies 1, and prevent the box bodies 1 from tipping over, leaking and being damaged.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
