The right end of the horizontal cover plate has a part extending towards the right, which is a right protruding part. The periphery of the horizontal cover plate has a downwardly extending lower extension edge. Among them, the left protruding part and its lower extension edge form a left buckle ear, and the right protruding part and its lower extension edge form a right buckle ear; on the inner side of the lower extension edge, there is a protruding strip; when the lid is buckled on the box body, the protruding strip is stuck in the drooping small hook of the convex hook part.
[0006] Furthermore, the extension edge has a part extending towards the left at the left ear piece, which is a second left protruding part. The second left protruding part and the left ear piece form a left inner groove; the extension edge has a part extending towards the right at the right ear piece, which is a second right protruding part. The second right protruding part and the right ear piece form a right inner groove.
[0007] Correspondingly, the horizontal cover plate has a downwardly raised portion near the left buckle ear, which is the lower left raised portion, and the horizontal cover plate has a downwardly raised portion near the right buckle ear, which is the lower right raised portion;
[0008] When the cover is buckled on the box body, the lower left raised portion is embedded in the left inner groove, and the lower right raised portion is embedded in the right inner groove.
[0009] Furthermore, the lower left raised portion is inserted into the left inner groove with an interference fit, and the lower right raised portion is inserted into the right inner groove with an interference fit.
[0010] Furthermore, the horizontal cover plate has an upwardly raised structure.
[0011] The beneficial effects of the utility model are: the lunch box does not get hot when held, which improves the dining experience; and when opening the lunch box, it can be opened from the left buckle ear or the right buckle ear, which is convenient and labor-saving; and because the left and right inner grooves and the left and right lower ridges are provided, the box and the lid are installed together more tightly and are not prone to leakage.
