【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments. As shown in FIG. 2, the present invention provides a specific embodiment of a lunch box comprising: a lunch box main body 400 and a lunch box cover 100. The lunch box cover 100 and the lunch box main body 400 are provided with a fastening for fastening the two. Structure 191; The top surface of the lunch box cover 100 is provided with a handle 130 for holding a lunch box, and the handle 130 is connected to the lunch box cover 100 by a hinge.

The lunch box cover 100 is provided with a groove 131 corresponding to the shape of the handle 130. The hinge connection is disposed on the inner walls of the two ends of the groove 131, the depth of the groove 131 and the thickness of the handle 130. In contrast, when not in use, the handle is placed in the recess 131, so that the flatness of the upper surface of the lunch box cover 100 can be maintained for convenient placement.

Both ends of the groove 131 are respectively provided with expansion grooves 133 which are a groove shape which is expanded on the side walls of both ends of the groove 131. The handle 130 can be more conveniently installed by the expansion slot 133, and a part of the installation space is vacated when the handle 130 is mounted.

A lug groove 132 is disposed on one side of the groove wall of the middle portion of the groove 131, and the setting of the lug groove 132 can more conveniently take out the handle 130 from the groove 131.

As shown in FIG. 3, the inside of the handle 130 has a hollow structure, and at the same time, a reinforcing rib 135 is disposed inside thereof, and the material of the handle can be saved by the hollow structure, and the strength of the handle can be increased by the rib. The ribs 135 are inclined relative to each other to form mutual support, thereby further enhancing the strength of the handle. Both ends of the handle are provided with pins 136 for engaging with pin holes (not shown) on the lunch box cover 100 to form a hinged connection.

As shown in FIG. 4, the inside of the lunch box is further provided with: a liner 200 disposed inside the lunch box main body 400 and a heating device 300, wherein the heating device 300 includes a layer attached to the outer surface of the inner liner 200. The heating sheet 301 is heated.

The heating sheet 301 is disposed on the bottom surface of the inner liner 200, and has a size and shape corresponding to the bottom surface of the inner liner 200, and is heated from the bottom surface of the inner liner 200, so that the heating sheet 301 is conveniently arranged and the heating effect is also more. it is good. Of course, it is also possible to attach the heating sheet to the entire outer circumferential surface of the inner liner 200, but this is not easy to process, and the heating sheet at the bottom has been able to meet the heating demand.
