[0003] In practical use, it has been found that working people frequently use lunchboxes to carry food, sometimes for weekday lunches, and sometimes for picnics or when traveling. Most lunchboxes on the market only have the basic function of holding food. Some lunchboxes have simple compartment designs that divide the interior into several areas, allowing for easy separation of staple foods and dishes, preventing cross-contamination and improving the dining experience to some extent. For example, common two- or three-compartment takeout lunchboxes have one compartment for rice and another for stir-fries. However, the inner and outer shells of existing lunchboxes are mostly one piece. If the food selection is small, the empty inner container still needs to be carried, increasing the weight. The compartment sizes of ordinary divided lunchboxes are fixed and cannot be adjusted according to individual dietary needs and preferences. For example, fitness enthusiasts or diabetics have different protein and carbohydrate intake requirements than ordinary people, but existing lunchboxes have fixed outer and inner shells, which cannot meet these personalized needs and limit the applicability of the lunchboxes. There are still some inconveniences in its use, so this technical solution is proposed for improvement. Utility Model Content

[0020] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] Example 1

[0022] See Figures 1 to 3 This utility model discloses a food container mainly composed of an outer shell 1, inner liner 3, connecting device, electric heating device, and end cap 2. The outer shell 1, as the main structure of the food container, is made of durable and heat-insulating material to ensure the freshness and temperature of the food. The outer shell 1 is provided with a heat insulation layer on the outside and a double-layer stainless steel layer on the inside to reduce heat loss and extend the heat preservation time. Multiple inner liners 3 are movably arranged inside the outer shell 1 through the connecting device. These inner liners 3 can be freely added, removed, or adjusted in position according to the user's dietary needs. The inner liners 3 are made of food-grade stainless steel material to ensure safety and harmlessness.

[0023] The inner liner 3 is also equipped with identification patterns, such as icons or text to distinguish food types, making it easy for users to quickly identify and manage different types of food. In addition, the inner liner 3 has different volumes for different food types, which helps people to use it as a long slot when holding food, increasing the rationality of food ratio and improving the effect of food pairing.

[0024] In addition, each inner liner 3 is spaced apart, and there is also a gap between the inner liner 3 and the inner wall of the outer shell 1. When carrying it out, hot water is filled between the outer shell 1 and the inner liner 3 to form an insulated area on the outside of the inner liner 3, which prolongs the heat preservation time of the food inside the inner liner 3, reduces the heating steps during picnics, and provides a good taste for the food. An end cap 2 is provided on the upper part of the outer shell 1. The upper part of the end cap 2 is provided with a receiving cavity 203 for placing tableware. The upper part of the receiving cavity 203 is provided with a lid, which makes it convenient for users to carry and store tableware. The upper surface of the end cap 2 is also provided with a handle 202 for easy lifting of the lunch box. The lower part of the end cap 2 is provided with a sealing layer that abuts against the top of the outer shell 1. The side of the end cap 2 is provided with a pressure handle 201 that connects to the side of the outer shell 1, which further enhances the stability of the lunch box. When the pressure handle 201 on the end cap 2 is fastened to the outer shell 1, the sealing layer can abut against the inner liner 3 and the outer shell 1. The pressure on the pressure handle 201 can tightly press the sealing layer, the outer shell 1, and the inner liner 3 together, making the outer shell 1 and the inner liner 3 an independent space. This prevents water from the inside of the outer shell 1 from entering the inner liner 3, and also prevents heat loss, ensuring the airtightness of the lunch box, preventing food leakage, and extending the heat preservation time.

[0025] The design of the connecting device allows the inner pot 3 to be installed securely and flexibly inside the outer shell 1. Specifically, the electric heating device is a heating plate 101 located at the bottom of the outer shell 1. A connecting buckle for connecting to a power source is provided on the outer wall of the outer shell 1. When used in the office, water is added inside the outer shell 1, and the heating plate 101 can heat the food inside the inner pot 3 to achieve the function of heating food. The connecting device includes a connecting seat 102 located on the upper surface of the heating plate 101, and a connecting post 301 located at the bottom of the inner pot 3 that engages with the connecting seat 102. This engaging design not only facilitates the installation and removal of the inner pot 3, but also ensures the stability of the inner pot 3 during use. At the same time, the number of inner pots 3 can be increased or decreased according to the needs of each use, reducing the weight carried each time, reducing the burden on people who bring their own meals, and improving the convenience of use.

[0026] Example 2

[0027] The main difference between this embodiment and embodiment 1 is that an annular groove is provided in the middle of the connecting seat 102, and the connecting post 301 is an annular post that is snapped into the annular groove. In order to enhance the stability of the connection, a snap ring is provided on the inner wall of the connecting post 301, and a snap protrusion that cooperates with the snap ring is provided inside the annular groove, so that the inner liner 3 can be firmly fixed in the outer shell 1 and is not easy to fall off even during movement.

[0028] Example 3

[0029] like Figure 7 The main difference between this embodiment and embodiment 2 is that a polygonal groove is provided in the middle position of the connecting seat 102, and the connecting post 301 is a hollow snap-fit ​​post that snaps into the polygonal groove. Compared with embodiment 2, this can ensure the stability of the inner liner 3 when snapped in, and prevent it from rotating inside, thus improving the stability of use.

[0030] It enables flexible food classification, convenient portability, and personalized needs to be met. At the same time, the electric heating device provides users with a more convenient heating method, allowing the lunch box to perform excellently in a variety of scenarios.
