At the same time, multiple lunch boxes are usually stacked when delivering meals, so that the upper box body is in direct contact with the lower box cover, which is easy to cause the lower box cover to be squeezed and deformed, and further makes the soup easy to leak, which greatly reduces the practicality of the lunch box. The utility model provides a sealed and seepage-proof lunch box.
[0006] The utility model provides a sealed and seepage-proof lunch box adopts the following technical scheme: a sealed and seepage-proof lunch box, comprising
[0007] The box body has a box cover at its upper end for sealing the box body;
[0008] The sealing mechanism is arranged at the bottom end of the box cover and is used to ensure the sealing and anti-seepage performance of the box cover when buckled on the box body;
[0009] The retaining ring is arranged at the upper end of the box body, and the box cover is located on the inner side of the retaining ring, which is used for protecting the box cover.
[0010] Preferably, the sealing mechanism comprises
[0011] A sealing ring is arranged at the bottom end of the box cover, and its outer side is in contact with the inner side of the box body;
[0012] A plurality of sealing rings are provided, and all of them are arranged on the outside of the sealing ring.
[0013] Preferably, a plurality of sealing grooves for use with the sealing ring are provided at the inner upper end of the box body, and the sealing ring is engaged with the sealing grooves.
[0014] Preferably, the upper end of the box cover is provided with sockets around it, and the bottom end of the box body is provided with plug blocks for use with the sockets around it.
[0015] Preferably, a plurality of tearing openings are provided on the outer side of the retaining ring to facilitate removal of the box cover from the box body.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] Through the above technical scheme, the sealed and anti-seepage lunch box disclosed by the utility model is provided with a sealing mechanism, a retaining ring, a sealing groove, a socket and an insert block. When the box cover is buckled on the box body, the cooperation of the sealing mechanism and the sealing groove makes the box cover more firmly buckled on the box body, and ensures the sealing and anti-seepage effect between the box cover and the box body. At the same time, the cooperation of the socket and the insert block makes it more stable when multiple box bodies are stacked and placed, and it is not easy to squeeze the box cover, thereby further ensuring the sealing and anti-seepage performance between the box cover and the box body.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model embodiment discloses a sealed and impermeable lunch box. Figure 1-4 A sealed and impermeable lunch box comprises a box body 1, a box cover 2 is arranged at the upper end of the box body 1 for sealing the box body 1, a sealing mechanism 3 is arranged at the bottom end of the box cover 2 for ensuring the sealing and impermeability of the box cover 2 buckled on the box body 1, a retaining ring 4 is arranged at the upper end of the box body 1, and the box cover 2 is located on the inner side of the retaining ring 4 for protecting the box cover 2;
[0025] Reference Figure 2 The sealing mechanism 3 includes a sealing ring 301 and multiple sealing rings 302. The sealing ring 301 is arranged at the bottom end of the box cover 2, and the outer side of the sealing ring 301 is in contact with the inner side of the box body 1. The multiple sealing rings 302 are all arranged on the outer side of the sealing ring 301; the upper end of the inner side of the box body 1 is provided with multiple sealing grooves 5 for use with the sealing rings 302, and the sealing rings 302 are snap-fitted into the sealing grooves 5.
[0026] By adopting the above technical solution, when the box cover 2 is buckled on the box body 1, the sealing ring 301 moves down along the inner side of the box body 1, and when the bottom end of the box cover 2 contacts the upper end of the box body 1, the sealing ring 302 is just engaged in the sealing groove 5. The box cover 2 can be fixed to the upper end of the box body 1 through the cooperation of the sealing ring 302 and the sealing groove 5, which is not easy to loosen, and the sealing and anti-seepage performance between the box cover 2 and the box body 1 is guaranteed.
[0027] Reference Figure 1 , Figure 2 and Figure 3 Sockets 6 are provided around the upper end of the box cover 2, and plug blocks 7 for use with the sockets 6 are provided around the bottom end of the box body 1.
[0028] By adopting the above technical solution, when multiple box bodies 1 need to be stacked, the plug block 7 on the corresponding box body 1 is inserted into the socket 6 on the corresponding box cover 2, which not only makes the multiple box bodies 1 highly stable when stacked, but also the box body 1 at the upper end is not easy to squeeze the box cover 2 at the lower end, thereby further ensuring the sealing and anti-seepage effect between the box cover 2 and the box body 1.
[0029] Reference Figure 4 A plurality of tearing openings 8 are provided on the outer side of the retaining ring 4 to facilitate the removal of the box cover 2 from the box body 1 .
[0030] By adopting the above technical solution, when the box cover 2 needs to be opened, one side of the retaining ring 4 is directly bent straight through the tearing opening 8 to expose a notch on the retaining ring 4, and the box cover 2 can be conveniently removed from the box body 1 through the notch.
[0031] Working principle: When the utility model is in use, the box cover 2 is buckled on the box body 1. At this time, the sealing ring 301 moves down along the inner side of the box body 1. When the bottom end of the box cover 2 contacts the upper end of the box body 1, the sealing ring 302 is just engaged in the sealing groove 5. The box cover 2 can be fixed to the upper end of the box body 1 through the cooperation of the sealing ring 302 and the sealing groove 5, and it is not easy to get loose. At the same time, the sealing ring 301 ensures the sealing and anti-seepage of the box cover 2 buckled on the box body 1, so that the soup in the box body 1 is not easy to seep out, and the retaining ring 4 makes the box cover 2 not easily affected by the outside When multiple box bodies 1 need to be stacked, the plug block 7 on the corresponding box body 1 is inserted into the socket 6 on the corresponding box cover 2, which not only makes the multiple box bodies 1 highly stable when stacked, but also the box body 1 at the upper end is not easy to squeeze the box cover 2 at the lower end, thereby further ensuring the sealing and anti-seepage effect between the box cover 2 and the box body 1. When the box cover 2 needs to be opened, one side of the retaining ring 4 is directly straightened through the tearing opening 8, so that a notch is exposed on the retaining ring 4, and the box cover 2 can be conveniently removed from the box body 1 through the notch.
[0032] When the utility model is in use, the box cover 2 is fastened on the box body 1 and has good sealing and anti-seepage performance. At the same time, when multiple box bodies 1 are stacked, the box cover 2 is not easily squeezed and is more stable, which greatly improves the practicality of the lunch box.
