Description

Technical Field

[0001] This utility model relates to the field of lunch box technology, specifically a built-in double-layer lunch box. Background Technology

[0002] A lunchbox is a box specifically designed to hold food, also known as a bento box. Most are made of aluminum, stainless steel, or plastic. Lunchboxes play an indispensable role in people's lives for storing food. With the rapid development of the food delivery industry and fast-paced lifestyles, the demand for disposable or reusable lunchboxes has increased significantly.

[0003] Traditional single-layer lunch boxes are widely used due to their simple structure and low cost, but they have obvious shortcomings in terms of functionality. Single-layer lunch boxes cannot separate food and dishes, and can only mix them together. They also have limited capacity. Furthermore, when carried out, the shaking can easily cause the food to mix together (especially when holding dishes with a lot of soup or curry). Upon arrival at the destination, the inside of the lunch box is unsightly and affects appetite. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a built-in double-layer lunch box to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a built-in double-layer lunch box, comprising a lunch box body, second springs installed on the inner walls of both sides of the lunch box body, a first support frame and a second support frame connected inside the lunch box body, a first spring connecting the first support frame and the lunch box body, a first serving box and a second serving box respectively placed on the top of the first support frame and the second support frame, and a lid connected to the top of the lunch box body by a latch.

[0006] Furthermore, the main body of the lunch box has first limiting grooves on both sides inside, and the first support plate is slidably connected to the first limiting grooves.

[0007] By adopting the above technical solution, the user puts the food into the first container and the second container respectively, then places the first container on the first support frame, and places the two second containers on the two second support frames respectively. After placing them, the user presses down on the first container, causing the first support frame to compress the first spring and move the first container down a certain distance. With the user pushing, the two second support frames move the second containers in opposite directions through the cooperation of the second limiting groove and the limiting rod. The two second support frames compress the second spring at the same time. When the top of the limiting rod is flush with the second limiting groove, the lid is placed on the top of the food container body and locked with the buckle. The food is contained separately by the first and second food container bodies, thus preventing the food from mixing together during transportation.

[0008] Furthermore, there are two second support frames, and the two second support frames are symmetrically distributed.

[0009] By adopting the above technical solution, when the user removes the lid, the first spring causes the first support frame to move the first serving box and the first support frame upwards, exposing the first serving box to the main body of the food container. At the same time, when the second support frame is flush with the top of the main body of the food container, the second spring causes the two second support frames to move the two second serving boxes in opposite directions, making room for the first serving box in the middle. In this way, the user can quickly enjoy the food without having to manually remove the first and second serving boxes after opening the lid.

[0010] Furthermore, a second limiting groove is provided inside the upper part of the main body of the lunch box, a limiting rod is connected to the top corner of the second support frame, and the second support frame is slidably connected to the second limiting groove through the limiting rod.

[0011] By adopting the above technical solution, the two second support frames are limited and guided by the cooperation of the limiting rod and the second limiting groove, thereby avoiding the displacement of the second support frame during the movement of the second container under the action of the second spring force, which would affect the practicality of the device.

[0012] Furthermore, there are two second containers, and both the second container and the first container are made of PP material.

[0013] By adopting the above technical solution, the food can be placed in two second containers, thereby increasing the capacity of the food container and allowing it to hold more food. PP material has excellent chemical stability, and the first and second containers made of it will not react harmfully with food, and the surface is smooth and easy to clean.

[0014] Furthermore, the first container and the second container are detachably connected to the first support frame and the second support frame, respectively.

[0015] By adopting the above technical solution, after the user finishes eating, the first and second serving boxes can be removed from the first and second support frames respectively and cleaned. The disassembly and assembly method is simple and quick, making it convenient for the user to use next time.

[0016] Furthermore, a handle is connected to the top of the lid, and the handle is rotatably connected to the lid.

[0017] By adopting the above technical solution and by setting up a handle, users can lift the main body of the lunch box by lifting the handle and move the main body of the lunch box, making it more convenient for users to take food out.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model is provided with a first holding box and two second holding boxes. The first holding box holds the staple food, and the two second holding boxes hold the dishes, thereby increasing the holding capacity of the meal box and enabling it to hold more food. At the same time, the food is held separately by the first meal box body and the second meal box body, thereby avoiding the food from mixing together during transportation and affecting the appetite when eating it later.

[0020] 2. This utility model is equipped with a first support frame, a second support frame, a first spring, and a second spring. After the user removes the lid, the first support frame moves the first serving box upward under the elastic force of the first and second springs, exposing the first serving box, the second support frame, and the second serving box to the main body of the lunch box. This allows the user to quickly enjoy the meal without having to manually remove the first and second serving boxes containing the food after opening the lid. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A built-in double-layer lunchbox, such as Figures 1-6 As shown, the device includes a lunchbox body 1. Second springs 8 are installed on the inner walls of both sides of the lunchbox body 1. A first support frame 3 and a second support frame 6 are connected inside the lunchbox body 1. A first spring 2 connects the first support frame 3 to the lunchbox body 1. A first serving box 5 and a second serving box 7 are respectively placed on the top of the first support frame 3 and the second support frame 6. A lid 11 is connected to the top of the lunchbox body 1 via a latch 12. First limiting grooves 4 are formed on both sides inside the lunchbox body 1, and a first support plate is slidably connected to the first limiting grooves 4. Users fill the first serving box 5 and the second serving box 7 with food, then place the first serving box 5 on the first support frame 3, and then place the two second serving boxes 7 on the first support frame 3. Place the food into the two second support frames 6 respectively. After placing them, press down on the first container 5, causing the first support frame 3 to compress the first spring 2 and move the first container 5 down a certain distance. With the push of the user, the two second support frames 6 move the second container 7 in opposite directions through the cooperation of the second limiting groove 10 and the limiting rod 9. At the same time, the two second support frames 6 compress the second spring 8. When the top of the limiting rod 9 is flush with the second limiting groove 10, put the lid 11 on the top of the food container body 1 and lock the lid 11 with the buckle 12. The food is then placed separately in the first food container body 1 and the second food container body 1, thus preventing the food from mixing together during transportation.

[0031] See Figure 2 , Figure 4 and Figure 5 In the above embodiment, there are two second support frames 6, which are symmetrically distributed. When eating, after the user removes the lid 11, the first support frame 3 moves the first serving box 5 and the first support frame 3 upward under the action of the first spring 2, exposing the first serving box 5 to the main body 1 of the food container. At the same time, when the second support frame 6 is flush with the top of the main body 1 of the food container, the two second support frames 6 move the two second serving boxes 7 in the opposite direction under the action of the second spring 8, leaving the middle position open for the first serving box 5. In this way, after the user opens the lid 11, they can quickly enjoy the food without manually taking the first serving box 5 and the second serving box 7 containing the food.

[0032] See Figure 3 , Figure 4 and Figure 5In the above embodiment, a second limiting groove 10 is provided inside the upper part of the main body 1 of the lunch box, and a limiting rod 9 is connected to the top corner of the second support frame 6. The second support frame 6 is slidably connected to the second limiting groove 10 through the limiting rod 9. The limiting rod 9 and the second limiting groove 10 cooperate to limit and guide the two second support frames 6, thereby preventing the second support frame 6 from shifting during the movement of the second container 7 under the action of the elastic force of the second spring 8, which would affect the practicality of the device.

[0033] See Figure 2 , Figure 3 and Figure 4 In the above embodiment, there are two second containers 7, and both the second container 7 and the first container 5 are made of PP material. By providing two second containers 7 to hold the food, the capacity of the food container is increased, so that it can hold more food. PP material has excellent chemical stability, and the first container 5 and the second container 7 made of it will not react harmfully with food, and the surface is smooth and easy to clean.

[0034] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In the above embodiment, the first container 5 and the second container 7 are detached from the first support frame 3 and the second support frame 6, respectively. After the user finishes eating, the first container 5 and the second container 7 are removed from the first support frame 3 and the second support frame 6, respectively, and then cleaned. The disassembly and assembly method is simple and quick, making it convenient for the user to use next time.

[0035] Example 2: To facilitate the transfer of the main body 1 of the lunch box by the user, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 6 The top of the lid 11 is connected to a handle 13, and the handle 13 is rotatably connected to the lid 11. By providing the handle 13, the user can lift the lunch box body 1 by lifting the handle 13, thereby moving the lunch box body 1, making it more convenient for the user to take food out.

[0036] The implementation principle of this utility model is as follows: The user puts the food into the first container 5 and the second container 7 respectively. Then, the first container 5 is placed on the first support frame 3, and the two second containers 7 are placed on the two second support frames 6 respectively. After placement, the first container 5 is pressed, causing the first support frame 3 to compress the first spring 2 and move the first container 5 down a certain distance. Then, the two second support frames 6 are pushed simultaneously. Through the cooperation of the second limiting groove 10 and the limiting rod 9, the two second support frames 6 move the second containers 7 in opposite directions. At this time, the two second support frames 6 compress the second spring 8 and compress the second spring 8 into the body of the food container 1. When the top of the limiting rod 9 is flush with the second limiting groove 10, the lid 11 is placed on top of the lunchbox body 1 and locked by the latch 12. When the user is enjoying the meal, the user opens the latch 12 and removes the lid 11. At this time, under the action of the first spring 2, the first support frame 3 moves the first serving box 5 and the first support frame 3 upward. At the same time, when the second support frame 6 is flush with the top of the lunchbox body 1, under the action of the second spring 8, the two second support frames 6 move the two second serving boxes 7 in the opposite direction, leaving the middle position open for the first serving box 5, thus exposing the first serving box 5 and the second serving box 7 to the lunchbox body 1, making it convenient for the user to enjoy the meal.
