         2 . The food container of  claim 1 , wherein an edge of the first connecting strip is bent toward the direction of the box bottom to form a first bent portion, and an edge of the second connecting strip is bent toward the direction of the cover plate to form a second bent portion; and when the box cover covers the opening of the box body, the first bent portion is fitted to and sealed against the second bent portion. 
     
     
         3 . The food container of  claim 2 , wherein the width of the second bent portion is greater than that of the first bent portion; the inner side of an edge of the second bent portion bulges to form a lock protrusion; and the lock protrusion extends to an edge of the second bent portion. 
     
     
         4 . The food container of  claim 1 , wherein the inner surface of the box wall is provided with a supporting step bulging from the inner surface; the upper surface of the supporting step is parallel to the box bottom, and the distance between the upper surface of the supporting step and the top of the box wall is equal to the height of the outer surface of the side wall of the box cover to support the cover plate of the box cover. 
     
     
         5 . The food container of  claim 1 , wherein the outer diameter of the bottom of the box wall is smaller than or equal to the inner diameter of the bottom of the side wall of the box cover. 
     
     
         6 . The food container of  claim 2 , the groove is formed by bending the first connecting strip. 
     
     
         7 . The food container of  claim 1 , wherein a plurality of reinforcing vertical ribs are arranged on the outer surface of the box wall. 
     
     
         8 . The food container of  claim 7 , wherein the plurality of reinforcing vertical ribs are uniformly arranged at intervals in a top area of the outer surface of the box wall, and the length of each reinforcing vertical rib is not greater than one fourth the height of the box body. 
     
     
         9 . The food container of  claim 7 , wherein a central part of the outer surface of the box bottom is recessed toward the direction of an accommodating space of the box body to form a convex ring at a peripheral edge of the outer surface of the box bottom. 
     
     
         10 . The food container of  claim 7 , wherein the outer surface of the box wall is provided with at least one anti-slip protrusion.
