[0002] Multifunctional stainless steel lunch boxes are containers made of stainless steel that can store and preserve food, fruits, etc. They are commonly used for food delivery and can reduce the use of disposable packaging products, which is beneficial to environmental protection and sustainable resource utilization.

[0003] Lunch boxes are typically stored by stacking, generally either with or without lids. When stacked without lids, the boxes can become difficult to separate after being compressed, and they also tend to bunch together during dishwasher washing, resulting in incomplete cleaning. With lids, stacking adjacent boxes can lead to instability due to valves on the lids, causing the stacked boxes to wobble or even tip over. Furthermore, traditional lunch boxes are single-chambered, offering limited functionality and practicality. Therefore, this application provides a multi-functional stainless steel lunch box to address the problems mentioned in the background. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] This utility model provides a technical solution, please refer to [link / reference]. Figures 1-8 A multifunctional stainless steel lunchbox includes a box body 1 and a lid 2. The lid 2 is made of stainless steel and has a prompt area for displaying relevant prompts during mold opening, reminding users of how to use the lunchbox. A raised air valve 6 is located in the center of the lid 2, used for sealing and releasing air after the lid 2 is fitted to the box body 1. The opening of the box body 1 has a downward-facing flange 11. An outer layer 3 is fitted over the box body 1, with its upper end inserted into the flange 11. Layer 3 is a silicone layer, melamine resin layer, plastic layer, tempered glass layer or bamboo fiber layer that is fitted onto the outer wall of box 1. The outer wall of box 1 and outer layer 3 are bonded together or formed into one piece by machine. It can be flexibly disassembled and assembled according to the usage scenario. While providing heat preservation and anti-fouling effects, it is also easy to clean. There are protrusions 8 in the middle of the four sides of the bottom of box 1. When box 1 is stacked, the protrusions 8 are used to separate two adjacent box 1s to avoid the inner walls of box 1 sticking together and making it inconvenient to take them out.

[0034] The box 1 has a QR code that stores food information, which users can scan to read the information for picking up or ordering food. The QR code on the box is a unique identification code for each box, which can be scanned to bind to the food delivery service, ensuring that the box can be traced back to its source for hygiene and safety after use.

[0035] The lower part of the outer wall of the box 1 is provided with a limiting groove 4. The limiting groove 4 is adapted to the shape of the opening port of the box 1. The limiting groove 4 is set at a distance of 2-3cm from the upper edge of the lunch box. The setting height of the limiting groove 4 must ensure that when the box 1 is stacked, there is space between the bottoms of two adjacent box 1s, so as to facilitate the flow of water and facilitate thorough soaking and cleaning.

[0036] The number of limiting grooves 4 is at least 3, preferably 4, to achieve reliable and stable support.

[0037] In the existing technology, when storing multiple lunch boxes, the boxes 1 are easily stacked. Because the stacked boxes 1 are pressed tightly together, they are not easy to take out. Moreover, when multiple lunch boxes are put into an automatic dishwasher for washing, they are also prone to stacking, resulting in insufficient cleaning of the boxes 1. This solution adds a limiting groove 4 on the outside of the lunch box. When the boxes 1 are stacked, the limiting groove 4 and the protrusion 8 provide support, leaving a certain gap between the two lunch boxes, preventing them from being pressed tightly together, thus facilitating separation.

[0038] Box 1 can be a cube, cuboid, cylinder, or frustum, as per the instruction manual. Figure 1As shown, the upper opening of box 1 is larger than the bottom of box 1, that is, the sides of box 1 are all trapezoidal, which facilitates the stacking of box 1. The bottom of box 1 is rounded to facilitate the use of box 1. The bottom of box 1 has an inward protrusion to form a groove 7 for accommodating the air valve 6 on the lid. The groove 7 design leaves more gaps between two stacked box 1, making it less difficult to pick up due to negative pressure. At the same time, the depth of groove 7 is greater than the height of the protrusion of air valve 6. When box 1 with lid 2 is stacked, the two adjacent box 1 will not tilt or become unstable due to the protrusion of air valve 6. In the prior art, when multiple lunch boxes are stacked together, the lower part of adjacent box 1 is easily pushed up by the setting of air valve 6, which causes the stacked structure to wobble and become uneven. This solution sets an inward recessed groove at the bottom of the lunch box, which can just accommodate the air valve 6 set on the lower lid 2, making the structure more flat when stacked.

[0039] The inner wall of the box 1 corresponding to the limiting groove 4 is concave, that is, it protrudes from the inner wall surface of the box 1. An inner lining isolation layer 5 is placed on the concave structure. The concave structure can support the inner lining isolation layer 5. The inner lining isolation layer 5 divides the interior of the box 1 into two layers, which can hold rice or vegetables respectively. The inner lining isolation layer 5 is divided into multiple chambers, which can be used to classify and hold side dishes. The inner lining isolation layer 5 is flexibly set and can be used as needed.

[0040] Example 2

[0041] The difference between this embodiment and embodiment 1 is that the outer layer 3 is an EP coating, PE coating or other environmentally friendly and non-toxic material coated on the outer wall of the box body 1, which serves to keep the contents warm and prevent burns.
