## Abstract

Provided is a food container which includes a box body with an opening and a box cover; the box body includes a box bottom and a box wall; a top edge of the box wall extends toward the outer side of the box body to form a first connecting strip; the first connecting strip is provided with a groove in the middle; the box cover includes a cover plate and a side wall; a top edge of the side wall extends toward the outer side of the box cover to form a second connecting strip; the middle of the second connecting strip protrudes to form a convex rib; when the box cover covers the opening of the box body, the convex rib of the box cover is embedded into the groove of the box body to form a seal structure. The food container is good at sealing performance.

## Claims

### Claim 1

A food container includes a box body with an opening and a box cover, wherein the box cover detachably covers the opening of the box body; the box body includes a box bottom and a box wall extending upward along the periphery of the box bottom; a top edge of the box wall extends toward the outer side of the box body to form a first connecting strip; the first connecting strip is provided with a groove in the middle, the opening direction of the groove being same as that of the box body, and the groove encircling the box body to form a closed ring; the box cover includes a cover plate and a side wall extending upward along the periphery of the cover plate; a top edge of the side wall extends toward the outer side of the box cover to form a second connecting strip; the middle of the second connecting strip protrudes toward the direction of the cover plate to form a convex rib; when the box cover covers the opening of the box body, the outer surface of the side wall of the box cover is fitted to the inner surface of the box wall of the box body, the convex rib of the box cover is embedded into the groove of the box body to form a seal structure.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 2)
