[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0030] Embodiment one: a sealed leakproof disposable paper lunch box solves the problem that the existing folding part needs to be folded into the connecting slot, and then an additional step is needed to achieve the purpose of covering, thereby causing the use to be inconvenient. The use of the first sealing glue 3 and the second sealing glue 4 can improve the sealing performance of use, and discloses:

[0031] The top of the box body 1 is attached with the box cover 2. The bottom of the box body 1 is fixed with the first sealing glue 3, and the bottom of the first sealing glue 3 extends into the inside of the second sealing glue 4 to constitute a sealing mechanism. The second sealing glue 4 is fixed on the top of the box body 1. The first sealing glue 3 is annularly arranged at the bottom of the box cover 2. The first sealing glue 3 is composed of rubber material. The first sealing glue 3 and the second sealing glue 4 constitute a fitting mechanism. The second sealing glue 4 is arranged in a "concave" shape. The second sealing glue 4 annularly surrounds the top of the box body 1. The second sealing glue 4 is composed of rubber material.

[0032] Reference Figures 1 to 5 ​Food is placed inside the box body 1, and then the box cover 2 is attached to the top of the box body 1, so that the box cover 2 drives the first sealing glue 3 to extend into the second sealing glue 4, so that the first sealing glue 3 and the second sealing glue 4 can be fitted, so that the first sealing glue 3 and the second sealing glue 4 can form a seal, thereby preventing the food soup in the box body 1 from spilling out, and only normal closing operation is required, and the convenience of use is also improved.

[0033] Embodiment two: a sealed leak-proof disposable paper lunch box solves the poor connection stability of the existing box cover 2 and the box body 1, and through the use of the buckle 5, the stability of the connection between the box cover 2 and the box body 1 is improved, which discloses:

[0034] The bottom of the box cover 2 is fixed with the buckle 5, and the bottom of the inner side of the buckle 5 is arranged in an inclined manner. The buckle 5 is arranged around the bottom of the box body 1, and the top of the buckle 5 is attached to the bottom of the outer side of the box body 1.

[0035] Referring to Figure 4 and Figure 5 , after the box cover 2 is attached to the box body 1, a pressing force is applied to the box cover 2, so that the box cover 2 can drive the buckle 5 to move, so that the movement of the buckle 5 can extrude the edge of the box body 1, and then the buckle 5 can extend into the bottom of the box body 1, so that the buckle 5 can tightly attach the box cover 2 and the box body 1, thereby improving the stability of the connection between the box body 1 and the box cover 2. When separating the box cover 2, the box cover 2 is pulled, so that the box cover 2 can drive the buckle 5 to extrude the box body 1, so that the buckle 5 is deformed by extrusion, so that the buckle 5 is separated from the box body 1, and then the box cover 2 is separated.

[0036] Embodiment three: a sealed leak-proof disposable paper lunch box solves the problem that the heat of the food in the existing box body 1 is transferred to the table top, thereby increasing the temperature of the table top.
