[0029] Please refer to Figure 1 , one embodiment of the present utility model provides a leak-proof lunch box, including: a box body 10 and a box cover 20.

[0030] The box body 10 is provided with a groove and a partition 11. The partition 11 divides the groove into a plurality of storage slots 12, and different dishes or rice can be respectively stored in the plurality of storage slots 12.

[0031] The box cover 20 is connected to the box body 10 for closing the storage slots 12. The box cover 20 is provided with a sealing assembly. The sealing assembly includes a driving member 21 and a sealing member 22. The driving member 21 is movably arranged on the box cover 20 and protrudes from the top of the box cover 20. The driving member 21 is in transmission connection with the sealing member 22. The sealing member 22 is arranged at the bottom of the box cover 20. A sealing groove 221 is arranged at the bottom of the sealing member 22. Sealing gaskets 222 are respectively arranged on the opposite inner side walls of the sealing groove 221. The sealing member 22 is configured to press against the box body 10 under the drive of the driving member 21, so that the top of the partition 11 and the edge of the groove extend into the sealing groove 221, and the sealing gasket 222 abuts against the side of the partition 11 or the side of the box cover 20, which is beneficial to improving the sealing performance.

[0032] The sealing groove 221 seals the top of the partition 11 and the edge of the groove, so that each storage groove 12 is sealed independently, and the food between each storage groove 12 cannot move relative to each other, thereby realizing separate storage of dishes. When the lunch box is moved, it is not easy for the food to move into the adjacent storage groove 12 due to shaking, and it is not easy for the food to leak out of the lunch box from the edge of the groove. In this embodiment, the partition 11 divides the groove into a middle storage groove 12 and a plurality of side storage grooves 12 arranged around the middle storage groove 12, the bottom of the box cover 20 closes the middle storage groove 12, and the sealing member 22 is annular and is used to close the side storage groove 12, so that the sealing member 22 can be adapted to press against the partition 11 and the edge of the groove after moving.

[0033] In some optional embodiments, the sealing member 22 is threadedly matched with the driving member 21, and the driving member 21 can drive the sealing member 22 to press against the box body 10 or away from the box body 10 after rotating, so that the user can drive the sealing member 22 to move by rotating the driving member 21. After the storage groove 12 is filled with food, the user twists the driving member 21 exposed from the top of the box cover 20, and the sealing member 22 can be driven by the driving member 21 to press against the box body 10, so that the edge of the partition 11 and the groove extends into the sealing groove 221. When it is necessary to open the box cover 20, the user can reversely twist the driving member 21 to make the sealing member 22 away from the box body 10, so that the edge of the partition 11 and the groove is separated from the sealing groove 221, so that it is convenient for the user to remove the box cover 20 from the box body 10.

[0034] In some optional embodiments, a button block 211 is provided on the top of the driving member 21 . The button block 211 is located on the top of the box body 10 . The button block 211 facilitates the user to rotate the driving member 21 .

[0035] To facilitate the installation of the seal 22 and the drive member 21, in some optional embodiments, an active cavity 223 is provided in the box cover 20, and an opening is provided at the bottom of the active cavity 223, and the top of the partition 11 and the edge of the groove extend into the opening. The seal 22 is movably arranged in the active cavity 223, and the seal 22 and the active cavity 223 are circumferentially limited. The drive member 21 is arranged in the active cavity 223 and extends from the top of the box cover 20 through the active cavity 223. The drive member 21 drives the seal 22 along the active cavity 223 to be pressed toward the box body 10 or away from the box body 10.

[0036] In some optional embodiments, a limiting groove 224 is provided in the active cavity 223, and a limiting block 212 is provided on the driving member 21. The limiting block 212 cooperates with the limiting groove 224 to limit the driving member 21 from approaching or moving away from the box body 10, thereby realizing position limitation of the driving member 21.

[0037] In some alternative embodiments, a first through hole 213, a gas valve 214, and an elastic member 215 are provided on the driving member 21, and a second through hole 23 is provided on the lid 20. The first through hole 213, the second through hole 23, and one of the storage grooves 12 communicate with each other. The gas valve 214 movably passes through the first through hole 213 and the second through hole 23. The top of the gas valve 214 extends outside the first through hole 213, and the bottom of the gas valve 214 closes the orifice of the second through hole 23. The elastic member 215 is connected to the driving member 21 and the gas valve 214 respectively. The elastic force of the elastic member 215 urges the gas valve 214 to press against the position of the lid 20 around the second through hole 23. Due to air pressure problems, it may be difficult to open the lid 20. The user can press the gas valve 214 into the storage groove 12, so that the gas valve 214 releases the closure of the orifice of the second through hole 23. At this time, the elastic member 215 is squeezed and deformed, and one of the storage grooves 12 communicates with the outside to balance the air pressure, thereby reducing the difficulty of opening the lid 20. Then, when the user releases the gas valve 214, the elastic force of the elastic member 215 can drive the gas valve 214 to reset.

[0038] In some alternative embodiments, a sealing block 216 is provided at the bottom of the gas valve 214. The gas valve 214 closes the orifice of the second through hole 23 through the sealing block 216. The sealing block 216 presses against the position of the lid 20 around the second through hole 23. The user can press the gas valve 214 into the storage groove 12, so that the sealing block 216 moves away from the position of the lid 20 around the second through hole 23, and the second through hole 23 is opened.

[0039] In some alternative embodiments, buckle grooves 13 are respectively provided on both sides of the box body 10, and buckle members 24 are respectively rotatably provided on both sides of the lid 20. The buckle members 24 are in buckle fit with the buckle grooves 13, thereby fixing the lid 20 and the box body 10. Of course, the box body 10 can also be detachably connected to the lid 20 in other ways, such as by a threaded fit between the box body 10 and the lid 20.

[0040] In some alternative embodiments, holding handles 14 are respectively provided on both sides of the box body 10 to facilitate the user to hold the box body 10. In this embodiment, the buckle grooves 13 are provided on the holding handles 14.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
