Specifically, based on practical manufacturing considerations, the main body of the lunch box is usually an integral indentation structure formed by indenting thin tin plates, and accordingly, two adjacent parts of the main body of the lunch box are integrally connected. In the embodiment of the present invention, the main body of the lunch box is divided into the bottom plate 9 and the side edges for the convenience of description.

Specifically, the side edges and the bottom plate 9 are formed according to the required structure of the main body of the lunch box, and are generally determined by a mould of the main body of the lunch box.

Specifically, the side edge comprises a first side plate 11, a second side plate 12, a third side plate 13 and a fourth side plate 14 which are connected into a whole in sequence, and the fourth side plate 14 is connected with the first side plate 11 into a whole; the first side plate 11 is opposite to the third side plate 13, and the second side plate 12 is opposite to the fourth side plate 14. Any two side plates are connected through a fillet with a large radian, correspondingly, the periphery of the bottom plate 9 is connected with the lower end of the side edge of the structure into a whole, and the shape of the bottom plate 9 is matched with the structure of the side edge.

With reference to the enlarged area structure shown in fig. 1 of the accompanying drawings, the turned edge 5 is turned over at a certain angle towards the outside of the lunch box main body, an arc surface 7 is formed at the turning position of the turned edge 5 along the inner wall of the side edge (the surface of the turning position in actual die pressing naturally forms a fillet), and a slope surface 8 is formed below the arc surface 7 along the inner wall of the side edge; specifically, the slope of this slope 8 is different with the slope that is located its below side edge, and this slope 8 is corresponding has formed a limit structure, and this slope 8 can supply the meal lid to cooperate spacingly in the in-service use, and the installation location of meal lid installation in the cutlery box main part of being convenient for has good convenience in use.

In addition, the side edge is provided with a curled edge 6 which is curled towards the upper part of the turned edge 5 at the tail end of the turned edge 5, the curled edge 6 can hide the sharp edge of the turned edge 5 on one hand to ensure the use safety of the lunch box body, and on the other hand, the curled edge 6 can form a horizontal limiting structure with a closed contour so as to further limit and position the lunch box cover.

Further, the side edge is also provided with a plurality of handle grooves 1; any one of the plurality of handle grooves 1 is a groove structure, wherein the outer wall of the side edge is sunken towards the inside of the lunch box main body at a preset position; any one of the plurality of grip grooves 1 has a grip surface positioned at the upper part; any one of the plurality of the grip grooves 1 is located below the slope surface 8.

Specifically, combine the structure that the figure illustrates, grip groove 1 is the side along the outer wall towards the inboard sunk structure of cutlery box main part, and the formation of this sunk structure can supply the formation of the face of shaking hands, and the formation of the face of shaking hands can provide sufficient position and supply the user to carry out effectual support to the cutlery box main part and hold, and the user of being convenient for gets the cutlery box main part and puts, improves the convenience in utilization of cutlery box main part.

Furthermore, the grip surface can be a plane or a curved surface. The planar grip surface has the beneficial effects that the shape is regular, and the design of the structures such as the reinforcing rib 3 structure, the supporting surface 2 structure and the like is facilitated.

Furthermore, in the plurality of shaking grooves 1, at least two shaking grooves 1 are arranged opposite to each other, so that a user can conveniently take and place the lunch box with two hands. In the specific implementation, the direction perpendicular to the bottom plate 9 is used for observation, and the orthogonal coordinate system is established by using the central point of the bottom plate 9 as the original point, so that the lunch box is divided into four quadrants, and the requirements of taking and placing the lunch box main body by two hands of a user can be met as long as at least two handle grooves 1 are respectively positioned in two opposite quadrants.

Furthermore, the side edge is also provided with a reinforcing rib 3 positioned below any one of the plurality of handle grooves 1, the reinforcing rib 3 has the function of ensuring the force transmission of the handle surface to the lunch box body due to the deformation prevention of the handle surface on one hand, and the whole side edge can be maintained to be stable in structure on the other hand.

Furthermore, the side edge is also provided with a supporting surface 2 which is positioned on the inner wall and is opposite to the handle surface, and the height of any supporting surface 2 does not exceed the lowest point of the slope surface 8. Specifically, since the main body of the lunch box is of an indent structure, and correspondingly, the side edges of the inner wall are formed on the opposite surfaces of the handle surface, in the embodiment of the utility model, the plane is further utilized. In particular, this surface is designated as a support surface 2, which is intended to provide a limited support for the meal cover in order to ensure the stability of the cover of the meal cover.

Further, all the supporting surfaces 2 are located on the same reference plane, the reference plane is parallel to the bottom plate 9, and the supporting surfaces 2 can effectively limit and position the meal cover.

Further, in any design structure, the side edges are provided with reinforcing ribs 3 positioned below the slope surface 8; the reinforcing ribs 3 are arranged along the direction of the connecting line of the upper ends of the side edges and the lower ends of the side edges; the reinforcing ribs 3 are convex rib structures with the side edges protruding towards the inner side of the lunch box main body or convex rib structures with the side edges protruding towards the outer side of the lunch box main body.

Correspondingly, as the surface area of the bottom plate 9 is larger, in order to avoid the deformation of the bottom plate 9 and maintain the structure of the bottom plate 8, the bottom plate 9 is provided with bottom plate reinforcing ribs 4; in particular, the floor stiffener 4 may be arranged in a grid pattern to provide a uniform support force.

Specifically, the setting of strengthening rib 3 can avoid the side to follow the deformation, effectively guarantees the structural stability on side edge.

Further, the highest points of all the reinforcing ribs 3 are located on the same reference plane, and the reference plane is parallel to the bottom plate 9. Due to the structural characteristics of the reinforcing ribs 3, the highest point of the reinforcing ribs 3 can be regarded as a limiting point, and a limiting plane which is established by a plurality of limiting points and used for limiting the meal cover can be formed through the matching of the highest points of the plurality of reinforcing ribs 3. In particular, the limit plane is parallel to the bottom plate 9.

In summary, the embodiment of the utility model provides a lunch box, which is convenient for positioning and mounting a lunch box cover by positioning and clamping the lunch box cover in a slope manner, prevents food from falling out, and has good use convenience.
