[0017] The following is combined with Figure 1-6 This application is described in further detail.

[0018] The present application embodiment discloses a disposable lunch box with a self-locking function, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, including a box body 1 and a box cover 2, the box cover 2 is movably sleeved on the top of the box body 1, and then the box body 1 can be closed, two fixing blocks 31 are fixedly connected to the edge of the box body 1, and two connecting blocks 32 are fixedly connected to the edge of the box cover 2, four card holes 33 are opened on one side of the two fixing blocks 31, and the four card holes 33 opened on one side of the two fixing blocks 31 are the same in distance between each other, and the two connecting blocks 32 are fixedly connected to one side close to the box body 1 with four triangular card blocks 34, and the four triangular card blocks 34 on one side of the two connecting blocks 32 are the same in distance between each other. In the process of buckling the box cover 2 on the top of the box body 1, the four triangular card blocks 34 on one side of the two connecting blocks 32 will respectively conflict with the two fixing blocks 31, and the four triangular card blocks 34 will give the two The connecting blocks 32 apply a reaction force to cause the two connecting blocks 32 to bend. Then, the four triangular blocks 34 on one side of the two connecting blocks 32 fall down and correspond to the four card holes 33 on one side of the two fixing blocks 31 respectively, and the moment the four triangular blocks 34 on one side of the two connecting blocks 32 are out of contact with the two fixing blocks 31, the two connecting blocks 32 will reset so that the four triangular blocks 34 on one side are respectively engaged in the four card holes 33 on one side of the two fixing blocks 31, and the inner top walls of the four triangular blocks 34 on one side of the two connecting blocks 32 will respectively conflict with the inner bottom walls of the four card holes 33 on one side of the two fixing blocks 31, thereby achieving the purpose of self-locking between the box cover 2 and the box body 1, preventing the box cover 2 and the box body 1 from easily losing contact.

[0019] Reference Figure 1 , Figure 3 Just and Figure 6 A limiting groove is provided at one end of the top of the box cover 2, and a circular hole is provided in the middle of the bottom wall in the limiting groove. A connecting strip 41 is fixedly connected to one side of the bottom wall in the limiting groove, and a sealing cover 42 is fixedly connected to one end of the connecting strip 41. The connecting strip 41 can limit the sealing cover 42 inside the limiting groove, and a protrusion 43 is fixedly connected to the middle of the bottom end of the sealing cover 42. The protrusion 43 is snap-connected to the inside of the circular hole to seal the circular hole and prevent the soup of the food placed in the box body 1 from escaping from the circular hole. A buckle block 44 is fixedly connected to one end of the top of the sealing cover 42, and the sealing cover 42 can be moved so that one end of the sealing cover 42 is lifted. During the process of lifting one end of the sealing cover 42, the protrusion 43 can be lifted so that the protrusion 43 can be removed from the circular hole.

[0020] Reference Figure 1 and Figure 3 A label placement area 51 is provided at the other end of the top of the box cover 2, and a blocking piece 52 is fixedly connected to the top of the inner wall of the label placement area 51. The label paper filled with food information can be inserted into the gap between the blocking piece 52 and the label placement area 51, and then the food information on the label paper can be obtained through the blocking piece 52 to know the type of food placed in the box body 1.

[0021] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 The two connecting blocks 32, a connecting strip 41 and a blocking piece 52 are all made of thermoplastic plastics, and the thermoplastic plastics are specifically polyethylene, which has high toughness and is not easy to break when bent during use and can be reset.

[0022] The implementation principle of the disposable lunch box with a self-locking function in the embodiment of the present application is as follows: when in use, food is placed inside the box body 1, and then the box cover 2 is buckled on the top of the box body 1. At this time, the four triangular clamping blocks 34 on one side of the two connecting blocks 32 will respectively contact the two fixed blocks 31, and the four triangular clamping blocks 34 will apply a reaction force to the two connecting blocks 32, so that the two connecting blocks 32 are bent. When the four triangular clamping blocks 34 on one side of the two connecting blocks 32 fall and correspond to the four clamping holes 33 on one side of the two fixed blocks 31 respectively, the four triangular clamping blocks 34 on one side of the two connecting blocks 32 are separated from the two fixed blocks 31. At the moment of contact, the two connecting blocks 32 will reset and the four triangular blocks 34 on one side will be respectively engaged in the four holes 33 on the side of the two fixing blocks 31, so as to achieve the purpose of self-locking between the box cover 2 and the box body 1 and prevent the box cover 2 and the box body 1 from being easily out of contact. Then, the sealing cover 42 is pressed to make the protrusion 43 engage and connect to the inside of the circular hole, so as to seal the circular hole and prevent the soup of the food placed in the box body 1 from escaping from the circular hole. Finally, the label paper filled with food information is inserted into the gap between the baffle 52 and the label placement area 51. After that, the food information on the label paper can be obtained through the baffle 52 to know the type of food placed in the box body 1.
