Patent No. 89218416 discloses a plastic snack box, which adopts a self-locking structure with two concave-convex steps to replace the plane matching of the original product, so that the snack box can not be opened by itself without being close to the outer edge after being closed, and the sealing performance is improved. However, when the snack box is deformed by extrusion, a gap is formed between the buckling parts of the box cover and the box body, and the soup cannot be effectively prevented from overflowing.

Chinese patent 200510042475.8 discloses a fully sealed ultra-thin food container which has excellent sealing performance and compressive strength, can effectively prevent food and soup from leaking, and has a box cover which is not easy to fall off when the flexible box body is squeezed. The box comprises a box cover and an open box body, wherein the edge of the box cover extends upwards to form an inner groove wall, the upper end part of the inner groove wall horizontally bends outwards to form a groove top, the outer end part of the groove top bends downwards to form an outer groove wall, an annular groove with a downward opening is formed by the inner groove wall, the groove top and the outer groove wall, a box opening of the box body extends upwards to form an inner straight edge, the upper end part of the inner straight edge horizontally bends outwards to form a flat edge, the outer end part of the flat edge bends downwards to form an outer straight edge, the inner straight edge, the flat edge and the outer straight edge form a box opening complex edge, a groove sleeve is buckled on the box opening complex edge, the inner side surface of the inner groove wall of the groove is jointed with the outer side surface of the inner straight edge of the box opening complex edge, a locking part is arranged at the joint part, a convex block which horizontally protrudes inwards is arranged on the inner side surface of the outer groove wall of the groove, the convex block locks the lower end part, And the lower end part of the groove is propped against the inner side surface of the outer groove wall of the groove.

In the invention, the inner side surface of the inner groove wall of the groove is jointed with the outer side surface of the inner straight edge of the box opening compound edge, and a lock catch part is arranged at the joint part to form an inner sealing structure; the outer straight edge of the box opening compound edge extends downwards and outwards in an inclined mode, and the lower end portion of the box opening compound edge is supported against the inner side face of the outer groove wall of the groove to form an outer sealing structure; the inner side surface of the outer groove wall of the groove is provided with a convex block which horizontally protrudes inwards, and the convex block locks the lower end part of the outer straight edge of the box opening compound edge to form an anti-tripping structure. Thereby realizing excellent sealing performance and compressive strength, effectively preventing the food soup from overflowing and leaking, and ensuring that the box cover is not easy to fall off when the flexible box body is extruded.

However, the invention still has the following disadvantages:

the outer straight edge of the box opening compound edge of the box body extends downwards and outwards in an inclined mode, and the lower end portion of the outer straight edge of the box opening compound edge of the box body is propped against the inner side face of the outer groove wall of the annular groove of the box cover. Because the lid corresponds the lid with uncovered box body and closes the back, the outer cell wall of the annular slot of lid is outside, including the outer straight edge on the box mouth complex edge of box body, when the position that the box mouth complex edge below received external force extrusion on the box body, can inwards cave in and warp, this box mouth complex edge receives an inside decurrent power of pulling, and the anticreep knot structure can be destroyed, and the lower tip on the outer straight edge on the box mouth complex edge can not the hasp on the lug of the outer cell wall medial surface of the annular slot of lid.
