[0002] Folding boxes are a common household container. Especially in this era of fast-paced life, many office workers often choose to use lunch boxes to carry meals to the company because of the short lunch break time, so as to solve the problem of eating. However, the existing lunch boxes have a single structure, and it is difficult to completely separate the dishes and rice in the lunch boxes. The rice will be stained with vegetable juice, resulting in a bad taste and poor appearance of the food. In some cases, the preservation of food also requires the lunch box to have a certain insulation effect to avoid the food from becoming cold and causing the food to taste bad, or even cause diarrhea to the eater. The existing lunch boxes cannot be folded, and they take up a large space after cleaning, which is not convenient to carry. The folding lunch boxes with multiple groups of storage chambers are not completely independent, so that although the food is placed separately, the smell between the foods can still float to other foods, affecting consumption.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0026] A preferred embodiment of the utility model is a multi-compartment folding lunch box that is easy to vent and has high air tightness; Figure 1-3 As shown, it includes a box body 10 with an opening on one side, a plurality of storage chambers for accommodating articles are arranged in the box body, a box cover 20 is connected to the opening of the box body, the opening is opened or closed by the box cover, and a ventilation device 30 is arranged on the box cover, and the air pressure in the box body is discharged by moving the air valve ventilation device to facilitate opening of the box cover.

[0027] Specifically, Figure 2 and Figure 4 As shown, the box body 20 is divided into two groups of storage chambers, wherein there are two groups of first storage chambers 102 for placing forks and spoons 40, and three groups of second storage chambers 103 for holding food. The second storage chambers are all formed in one piece by the peripheral wall 100 and the bottom wall 101, and the peripheral wall and the bottom wall are surrounded to form the second storage chamber. There are multiple groups of folding parts 1000 distributed up and down on the peripheral wall, and the peripheral wall is folded or opened by the folding part, so as to fold or open the second storage chamber. There are multiple groups of foot pads 105 on the bottom wall 101 of the second storage chamber, and the foot pads support the foldable lunch box and increase the friction of the foldable lunch box. In order to make each second storage chamber foldable separately, a gap 104 is provided between the peripheral walls 100, so that the three groups of second storage chambers are independent of each other. The box body is also provided with an outer flange 111 extending to the surroundings, and a lower flange 106 is provided at the end of the outer flange, so that a circle of supporting parts 107 is formed at the bottom of the box body, and the supporting parts facilitate the taking and placing of the lunch box.

[0028] Furthermore, if Figure 1 , Figure 3 and Figure 6As shown, in order to facilitate viewing of the number of storage chambers of the lunch box, a recessed portion 201 is provided on the box cover corresponding to each group of storage chambers, and the specific number of storage chambers in the folding box can be obtained through the recessed portion. The box cover is provided with a chamber cover 204 corresponding to each group of second storage chambers 103. When the box cover is set on the box body, the chamber cover covers the second storage chamber. And each group of chamber covers is provided with an interference column 203. The interference between the interference column and the inner wall 110 forms a sealed environment in the second storage chamber, thereby keeping the food in the second storage chamber warm and fresh. In order to increase the sealing performance of the box cover and the box body, a sealing groove 202 is provided on the box body, and a sealing strip 109 is provided on the box cover corresponding to the sealing groove to further seal the box cover and the box body.

[0029] Furthermore, if Figure 1 and Figure 3 As shown in FIG. 1 , after food is put into the foldable lunch box, the hot air makes the lid and the box body in close contact, and due to the sealing effect of the interference column and the inner wall, the foldable lunch box is difficult to open. Figure 5-7 As shown, a through hole 206 is provided on the box cover, and a connecting ventilation device 30 is provided in the through hole. The ventilation device is connected to the storage chamber. When the ventilation device is pulled out, the ventilation device can be ventilated to discharge the hot air in the storage chamber, so that the foldable lunch box is convenient to open.

[0030] Furthermore, if Figure 5-6 As shown, the three groups of chamber covers 204 are all provided with mouths 205 at the corresponding through holes, and the ventilation device 30 includes a stopper foot 303 arranged at the mouth, and the stopper foot is provided with an air outlet 304, and the three groups of stopper feet are connected to the valve column 301, the valve column passes through the through hole 206, and the upper end of the stopper column is connected to the valve cover 300, the valve cover is placed outside the box cover, and a stopper ring 302 is provided on the valve column, and the stopper ring can move between the through holes. A vent hole 306 connected to the outside world is provided on the valve column. When the stop foot is placed at the mouth and the stop ring 302 contacts the inner wall of the through hole, the lower surface of the valve column contacts the connecting part. At this time, the air outlet hole contacts the surrounding wall and cannot complete air circulation. When the valve cover is pulled to make the stop ring pass through the through hole, the stop foot moves at the mouth and the lower surface of the valve column does not contact the connecting part. The pulling is continued until the air outlet hole does not contact the surrounding wall. At this time, air circulation is formed between the air outlet hole and the vent hole, and the hot air in the storage room is discharged through the air outlet hole and the vent hole, so the box cover can be opened, and only one deflation action is required to deflate the three groups of storage chambers at the same time, which is more convenient to operate.

[0031] Furthermore, the lunch box of the utility model is made of food-grade materials, and its good sealing property also improves the heat preservation property of the lunch box, and facilitates the storage and opening of the lunch box. After storage, it saves space and is more convenient to use.

[0032] When in use, the utility model is explained by taking the folding lunch box as an example, unfolding the folding part 1000 to unfold the box body, placing the cooked food in the second storage chamber 103, and placing the fork, spoon, etc. in the first storage chamber 102, closing the box cover 10 at the opening, and placing the chamber cover on each group of second storage chambers, making the second storage chambers independent, and inserting the sealing strip 109 into the sealing groove 202 to connect the box cover with the box body, pressing the ventilation device 30 to make the retaining ring 302 pass through the through hole into the box cover, at this time, due to the movement of the valve column, the retaining foot 303 moves downward in the mouth 205, and the air outlet 304 contacts the surrounding wall until the lower surface of the valve column contacts the connecting part, at this time, the ventilation device is sealed and closed, so as to keep the food in the folding lunch box warm and fresh. When it is time to eat, pull the valve cover to make the retaining ring pass through the through hole. At this time, the retaining foot moves upward with the valve column, and the lower surface of the valve column is away from the connecting portion. When the air outlet hole is not in contact with the inner wall, air circulation is formed between the air outlet hole and the air release hole, thereby exhausting the air in the second storage chamber. At this time, the box cover can be opened to eat the food in the foldable lunch box.
