Technical Field
[0001] The utility model belongs to the technical field of lunch box processing, and in particular relates to a scald-proof disposable plastic lunch box. Background Art
[0002] Lunch boxes are tableware required for food packaging and take-out. They are widely used in people's daily lives and bring great convenience to people. Among them, plastic lunch boxes have become the mainstream lunch boxes in daily life due to their good sealing, strong plasticity, simple production and relatively low cost. However, plastic lunch boxes also have shortcomings in actual use: (1) Due to the poor thermal insulation of plastic materials, when taking and putting plastic lunch boxes, the diners' fingers are in contact with the outer side of the plastic lunch box, which can easily cause burns and discomfort to the diners' fingers; (2) High-temperature food and steam can cause the lunch box to expand and deform. When consumers open the lunch box, food is likely to splash and burn. (3) When the lunch box needs to be placed in a microwave oven to reheat the food inside, in order to prevent the lunch box from bursting due to the seal, the lid of the lunch box can only be slightly opened, which can easily cause odor contamination and affect the taste of the food. Therefore, in order to solve the above problems, it is necessary to develop a scalding-proof disposable plastic lunch box with good scalding effect and convenient use and taking and putting operations.

DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a scald-proof disposable plastic lunch box comprises a box body 1, a box cover 2 and a sealing plug 3. The box body 1 is a circular groove-shaped structure with an opening at the upper end. The outer fixed sleeve at the upper end opening is provided with a connecting guard edge 11. The upper ends of both side surfaces are fixedly provided with a pick-up and drop-off plate 12. The outer fixed sleeve of the connecting guard edge 11 is provided with an annular limit block 13. An arc-shaped protective plate 14 is fixedly provided below one end of the pick-up and drop-off plate 12 connected to the outer surface of the box body 1, and the protective plate 14 and the box body 1 do not contact each other. A pick-up and drop-off buckle groove 15 is provided below the other end. The box cover 2 is located above the box body 1, and the outer end of its lower surface is fixedly provided with a There is an annular limiting guard edge 21, which is sleeved on the outside of the connecting guard edge 11, and the inner surface of the limiting guard edge 21 is provided with a limiting groove 22 that matches the annular limiting block 13 structure. An exhaust hole 23 is vertically provided at the center of the box cover 2. The lower end of the sealing plug 3 is located inside the exhaust hole 23 and is in close contact with the inner wall of the exhaust hole 23. The upper end is located above the box cover 2 and is concentrically fixedly connected with a vertical rod 4. Connecting rods 5 are provided on both sides of the vertical rod 4. The connecting rod 5 is L-shaped as a whole, one end of which is fixedly connected to the outer side surface of the vertical rod 4, and the other end is limitedly connected to the upper surface of the box cover 2 through a point-breaking block 51.
[0019] The outer surface of the annular limit block 13 is arc-shaped. By utilizing this structure, the smoothness of the connection between the annular limit block 13 and the limit groove 22 can be increased; the bottom surface of the take-and-place buckle groove 15 is fixedly provided with a non-slip pad; the lower end of the box body 1 is fixedly provided with a heat-insulating base 6, and the heat-insulating base 6 can be used to insulate the lower part of the box body, and a chopstick placement groove 61 is horizontally arranged at the center of the heat-insulating base 6. The chopstick placement groove 61 can facilitate the unified placement of chopsticks to avoid the problem of contamination and loss of disposable tableware.
[0020] When the lunch box is taken and placed before opening, the utility model can utilize the cooperation of the two taking and placing plates 12 and the setting of the taking and placing buckle grooves 15 at the outer ends of the lower surfaces of the taking and placing plates 12 to increase the convenience of the overall operation of taking and placing the lunch box. At the same time, the isolation and protection function of the protective plate 14 can prevent the contact between the fingers and the outer side of the box body 1, thereby achieving an anti-scalding effect.
