Description

Technical Field

[0001] The utility model relates to the technical field of disposable lunch boxes, and particularly relates to a disposable tableware with a built-in lock and seal. Background Art

[0002] The use of disposable tableware is one of the food carriers in the modern catering takeaway industry and occupies a very important position in the entire takeaway industry. There are more or less problems in food packing and takeaway transportation. For example, the sealing performance of the lunch box is not good, and the food with soup is easy to spill during transportation. The hardness and quality are insufficient, and it is easy to deform after loading heated food. To add more guarantee to the transportation process, after adding a locking port, if it is opened for the second time, the safety buckle at the box mouth must be broken, which can prevent the food from being opened halfway.

[0003] To solve the above problems, the Chinese Patent Network publication number: CN201820986397.X discloses a disposable tableware with a built-in lock and seal. Although it can solve the above problems, when the lunch box is used, if fried food is put in it, during transportation, the steam released by the food cannot dissipate and will remain in the lunch box, thereby wetting the food and affecting the taste of the food.

[0004] To solve this problem, the present utility model is thus produced. Content of the Utility Model

[0005] Therefore, in view of the above problems, the present utility model provides a disposable tableware with a built-in lock and seal, which has a simple structure, can exhaust air, and is convenient for placing food.

[0006] To solve the above technical problems, the solution adopted by the present utility model is: a disposable tableware with a built-in lock and seal, including a lunch box body and a lid provided on the lunch box. An exhaust passage penetrating the lid is provided on the lid, and an opening and closing device for opening or closing the exhaust passage is provided at the exhaust passage on the lid.

[0007] Further improvement is: the opening and closing device includes a fixed ring, the fixed ring is provided on the lid and at the position of the exhaust passage, a fixed plate is provided inside the fixed ring, fan-shaped passages penetrating the fixed plate are symmetrically provided on the fixed plate, the fan-shaped passages are communicated with the exhaust passage, and a sealing device for sealing the exhaust passage is provided on the fixed plate.

[0008] Further improvement is: the sealing device includes a sealing plate, the sealing plate is provided with a breathable passage penetrating the sealing plate in a shape matching the fan-shaped passage, the sealing plate abuts against the fixed plate, and a rotating rod is rotatably provided on the fixed plate, and the sealing plate is provided on the rotating rod.

[0009] Further improvement is: a filter screen is provided in the exhaust passage.

[0010] Further improvement is that a rotating groove is formed on the rotating rod.

[0011] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows:

[0012] The structure is simple and convenient for placing food. When in use, when the lunch box is filled with fried food or food that needs to discharge steam, the ventilation channel is overlapped with the fan-shaped channel, so as to open the exhaust channel, and then the emitted steam can be discharged, preventing the steam from being trapped in the lunch box and affecting the taste of the food. When the lunch box is filled with soup-like food, the ventilation channel is staggered from the fan-shaped channel, so as to seal the fan-shaped channel, and then seal the exhaust channel, so that the soup can be prevented from overflowing during transportation, which is beneficial to transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 3 is a schematic structural diagram of an opening and closing device in an embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Refer to Figures 1 - 3 , what is disclosed in the embodiment of the present utility model is: a disposable tableware with a built-in lock and seal, including a lunch box body 1 and a lid 2 provided on the lunch box. An exhaust channel 3 penetrating through the lid 2 is provided on the lid 2, and an opening and closing device for opening or closing the exhaust channel 3 is provided at the position of the exhaust channel 3 on the lid 2.

[0018] Specifically, the opening and closing device includes a fixed ring 5 and a sealing plate 7. The fixed ring 5 is provided on the lid 2 and at the position of the exhaust channel 3. A fixing plate 6 is provided inside the fixed ring 5. Sector-shaped channels 9 penetrating through the fixing plate 6 are symmetrically provided on the fixing plate 6. The sector-shaped channels 9 are communicated with the exhaust channel 3. A ventilation channel penetrating through the sealing plate 7 is provided on the sealing plate 7 in a shape matching the sector-shaped channels 9. The sealing plate 7 abuts against the fixing plate 6. A rotating rod 8 is rotatably provided on the fixing plate 6, and the sealing plate 7 is provided on the rotating rod 8.

[0019] When in use, when fried food or food that needs to exhaust steam is placed in the lunch box, the sealing plate 7 is rotated so that the air permeable channel overlaps with the fan-shaped channel 9, thereby opening the exhaust channel 3, and then allowing the emitted steam to be exhausted, preventing the steam from being trapped in the lunch box and affecting the taste of the food. When soup-like food is placed in the lunch box, the sealing plate 7 is reversed so that the air permeable channel is staggered with the fan-shaped channel 9, thereby sealing the fan-shaped channel 9, and then sealing the exhaust channel 3, so that the soup can be prevented from overflowing during transportation, which is conducive to transportation.

[0020] In order to prevent impurities from flying into the exhaust passage 3 and contaminating food when the exhaust passage 3 is opened, a filter 4 is provided in the exhaust passage 3.

[0021] In order to facilitate the rotation of the rotating rod 8 , a rotating groove is provided on the rotating rod 8 .

[0022] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
