[0010] Furthermore, the rotation limiting ring is made of elastic plastic material.

[0011] The beneficial effects of the utility model are as follows: prepared food is introduced into the plastic packaging box, the opening of the plastic packaging box is covered by the cover body, the box body wrapping ring below is positioned and wrapped with the top of the plastic packaging box, and the high-temperature hot air generated by the food is discharged through the exhaust hole. When it needs to be delivered, the handle is rotated so that the handle drives the arc-shaped sealing piece to rotate above the exhaust hole. After the sealing block is embedded in the exhaust hole, the sealing work is completed and a part of the hot air is discharged in advance. During the short period of delivery, the plastic packaging box will not be caused to expand. This structure can effectively prevent soup from spilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Other features, objects and advantages of the present invention will become more apparent by reading the detailed description of non-limiting embodiments with reference to the following drawings:

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] See also Figure 1 , Figure 2 The utility model provides a technical solution for a plastic cover with high sealing degree: its structure includes a cover body 1 and a handle 2. A positioning plate 3 is provided at the center of the upper end of the cover body 1. The handle 2 is rotatably arranged on the upper end of the positioning plate 3. A rotating shaft 4 is provided at the center of the upper end of the positioning plate 3. A rotating groove 5 rotatably sleeved with the rotating shaft 4 is provided on the lower end surface of the handle 2. A rotating limiting ring 6 is provided on the outer wall of the rotating shaft 4. An annular rotating groove 7 rotatably engaged with the rotating limiting ring 6 is provided on the inner wall of the rotating groove 5. An exhaust hole 8 is provided on the cover body 1. An arc-shaped sealing sheet 9 covering the exhaust hole 8 is provided on one side of the bottom of the handle 2. A sealing block 10 sealingly embedded in the exhaust hole 8 is provided on the bottom surface of the arc-shaped sealing sheet 9. A box body wrapping ring 11 is provided on the bottom surface of the cover body 1.

[0017] In order to improve the firmness of the connection, the positioning plate 3, the cover body 1, and the box body connecting ring 11 are an integrated structure.
