Arrows are provided on the surface of the knob, and corresponding locking, unlocking, and disengagement markings are provided on the surface of the lid. These markings indicate which marking the knob is rotated to when it is turned, facilitating subsequent operations. Several raised ribs are provided on the lid, contacting the bottom surface of the knob. This contact prevents wear on the lid surface and keeps it smooth. The bottom of the rotating groove is also provided with an exhaust hole, and the bottom surface of the knob is provided with an exhaust pressure block. The exhaust pressure block cooperates with the exhaust hole. When the knob is turned to the locked position, the exhaust pressure block presses on the exhaust hole, and the entire food storage container is in a sealed state, with good freshness preservation effect. When the knob is turned to the unlocked position, the exhaust pressure block separates from the exhaust hole, and the exhaust hole can release air. One side of the lock hole is provided with a bevel, which facilitates the locking plate to enter the lock hole. The outer wall of the container is fitted with an outer shell, which has perforations for an aesthetically pleasing appearance. The bottom of the outer shell is provided with feet, which provide stability and facilitate the stacking of two food storage containers. The sealing structure includes a groove on the inner wall around the opening of the container, in which a sealing ring with a triangular cross-section is placed. A sealing pressure ring is provided under the lid, which cooperates with the sealing ring. When the lid is closed, the sealing pressure ring presses down on the sealing ring, resulting in a better sealing effect. The lid is also equipped with a fork slot and a knife slot. A fork is placed in the fork slot and a knife is placed in the knife slot. It can be used as a lunch box or food container. With a fork and a knife, it is convenient to use.
