[0002] With the continuous development of society, people's life rhythm has accelerated, and the demand for disposable tableware has also increased rapidly. However, since most ordinary lunch boxes and lunch box covers are not easily degradable and non-recyclable, it is rather troublesome for people to handle them, and it will also cause serious pollution to the environment.
[0003] Nowadays, most disposable lunch boxes are composed of a box body and a box cover. Not only is the sealing performance poor, but also since most lunch boxes are made of plastic, the bottom lunch box cover may crack due to being unable to bear the gravity during stacking, affecting the sealing performance of the lunch box. Moreover, since the tops of existing box covers are mostly flat and smooth, when multiple lunch boxes need to be stacked for transportation, it is not only unfavorable for the lunch boxes to be stacked, but also prone to slipping, resulting in the spilling of the food in the lunch box. To solve the above problems, there is an urgent need for a recyclable and environment-friendly lunch box cover to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems that most disposable lunch boxes nowadays are composed of a box body and a box cover, not only with poor sealing performance, but also since most lunch boxes are made of plastic, the bottom lunch box cover may crack due to being unable to bear the gravity during stacking, affecting the sealing performance of the lunch box, and since the tops of existing box covers are mostly flat and smooth, when multiple lunch boxes need to be stacked for transportation, it is not only unfavorable for the lunch boxes to be stacked, but also prone to slipping, resulting in the spilling of the food in the lunch box, and to propose a recyclable and environment-friendly lunch box cover.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a recyclable and environment-friendly lunch box cover, including a lunch box cover, a top cover is fixedly installed on the top surface of the lunch box cover, a cover ear is fixedly installed on the outer wall of the lunch box cover, a fixing component is arranged on the top of the lunch box cover, and a sealing and supporting component is arranged inside the lunch box cover.
[0006] As a further description of the above technical scheme:
[0007] The fixing component includes a limiting ring, a limiting ring is fixedly installed on the top surface of the lunch box cover, and a spring is fixedly connected to the inner wall of the limiting ring.
[0008] As a further description of the above technical scheme:
[0009] One end of the spring is fixedly connected with a friction pad, and the friction pad is in contact with the outer wall of the top cover. Two friction pads are arranged inside the limiting ring.
[0010] As a further description of the above technical solution:
[0011] The sealing and supporting assembly includes an air pipe. The air pipe is fixedly installed on the outer wall of the lunch box cover. A plug is slidably connected inside the air pipe. One end of the plug is fixedly installed with a threaded rod, and one end of the threaded rod is fixedly installed with a pull rod. The air pipe is threadedly connected with the threaded rod through a threaded hole provided inside it.
[0012] As a further description of the above technical solution:
[0013] An installation frame is fixedly installed on the inner wall of the top cover. A support frame is fixedly installed on the bottom surface of the installation frame. A support frame is fixedly installed on the top inner wall of the lunch box cover. A blocking frame is fixedly installed on one side surface of the support frame. The lunch box is slidably connected with the blocking frame through a groove provided inside it.
[0014] As a further description of the above technical solution:
[0015] A sealing ring is fixedly installed on the inner wall of the lunch box cover. The inner wall of the sealing ring is in contact with the outside of the lunch box. Both the lunch box cover and the top cover are made of environmentally friendly high-temperature resistant materials.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:
[0017] 1. In the present utility model, by providing a sealing support assembly and a fixing assembly, when the device is applied and the lunch boxes are stacked, first pull the two friction pads apart, and the spring is compressed. Then place the bottom end of another lunch box between the limit ring and the top cover. After that, release the friction pads, and the spring resets and clamps and fixes the other lunch box. During the stacking process, since the mounting rack, the support frame, and the blocking frame are fixed to each other, the force borne by the lunch box lid and the top cover during stacking can be distributed to the lunch box. In order to ensure the airtightness inside the lunch box, before transporting it, a part of the air inside the lunch box can be pumped out through an air pipe, so that the pressure inside the lunch box is lower than the outside, thereby enabling the lunch box lid to closely adhere to the lunch box. After pumping out the air, then turn the plug into the threaded rod through the pull rod. Before heating the lunch box, the plug can be turned out through the pull rod to prevent the lunch box body and the lid from bulging due to softening when heated or blocked exhaust during heating, thus avoiding the occurrence of a large safety hazard. Through this design, not only can the lunch boxes be stacked smoothly, facilitating the transportation of the lunch boxes, but also the airtightness and bearing capacity of the lunch boxes can be further improved, avoiding the situation that most lunch boxes are composed of a box body and a lid, with poor airtightness, and since most lunch boxes are made of plastic, the lid of the bottom lunch box cracks due to being unable to bear the gravity during stacking, thereby affecting the airtightness of the lunch box. At the same time, it can also avoid the situation that most of the existing lid tops are flat and smooth. When multiple lunch boxes need to be stacked for transportation, it is not only not conducive to stacking the lunch boxes, but also easy to cause slipping, resulting in the food in the lunch box spilling out. Moreover, it is simple and convenient to use and has strong practicability.
[0018] 2. In the present utility model, by providing a sealing ring, during the use of the device, the setting of the sealing ring can not only further improve the airtightness of the lunch box and further extend the shelf life of the food, but also because the sealing ring itself has a certain friction, it can prevent the lunch box lid from falling off during the transportation of the lunch box to a certain extent, thus preventing the food in the lunch box from spilling out. It is simple and convenient to use and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific implementation method is as follows: When the device is in use and stacking lunch boxes, first pull the two friction pads 32 apart, and the spring 33 is compressed. Then place the bottom end of another lunch box between the limit ring 31 and the top cover 4. After that, release the friction pads 32, and the spring 33 resets and clamps and fixes the other lunch box. During the stacking process, since the mounting bracket 25, the support bracket 26, and the blocking bracket 27 are fixed to each other, the force borne by the lunch box lid 1 and the top cover 4 during stacking can be shared by the lunch box. In order to ensure the airtightness inside the lunch box, before transporting it, a part of the air inside the lunch box can be pumped out through the air pipe 24, making the pressure inside the lunch box lower than the outside, so that the lunch box lid 1 can closely adhere to the lunch box. After pumping out the air, then turn the plug 23 into the threaded rod 22 and the plug 23 through the pull rod 21. Before heating the lunch box, the plug 23 can be turned out through the pull rod 21 to prevent the lunch box from bulging due to the softening of the box body and the lid or the blockage of air exhaust during heating, which may cause a greater safety hazard.

[0030] The specific implementation method is as follows: During the use of the device, the setting of the sealing ring 6 can not only further improve the airtightness of the lunch box and further extend the shelf life of the food, but also, due to the certain friction of the sealing ring 6 itself, it can prevent the lunch box lid 1 from falling off during the transportation of the lunch box to a certain extent, thus preventing the food inside the lunch box from spilling out.
[0031] Working principle: When this device is applied, when stacking lunch boxes, first pull the two friction pads 32 apart, and the spring 33 is compressed. Then place the bottom end of another lunch box between the limit ring 31 and the top cover 4. After that, release the friction pads 32, and the spring 33 resets and clamps and fixes the other lunch box. During the stacking process, since the mounting frame 25, the support frame 26, and the blocking frame 27 are fixed to each other, the forces borne by the lunch box lid 1 and the top cover 4 during stacking can be shared by the lunch box. In order to ensure the airtightness inside the lunch box, before transporting it, a part of the air inside the lunch box can be pumped out through the air pipe 24, so that the pressure inside the lunch box is lower than the outside, so that the lunch box lid 1 can closely adhere to the lunch box. After pumping out the air, then turn the plug 23 into the threaded rod 22 and the plug 23 through the pull rod 21. Before heating the lunch box, the plug 23 can be turned out through the pull rod 21 to prevent the lunch box from bulging due to the softening of the box body and the lid or the blocked exhaust during heating, which may cause a greater safety hazard. During the use of this device, the setting of the sealing ring 6 can not only further improve the airtightness of the lunch box and further extend the shelf life of the food, but also because the sealing ring 6 itself has a certain friction, it can prevent the lunch box lid 1 from falling off during the transportation of the lunch box to a certain extent, so as to prevent the food inside the lunch box from spilling out.
