[0023] With the rapid development of the take-out and fast food industry, the use of food lunch boxes is increasing. Traditional food lunch boxes are usually made of paper, plastic or foam materials, and play an important role in food storage and transportation. However, the lunch boxes commonly used on the market have a significant defect, that is, insufficient pressure bearing capacity. In actual application, especially in the logistics distribution link, food lunch boxes often need to bear pressure from above. Whether in the stacking process inside the delivery vehicle or accidental extrusion during handling, it can cause serious damage to the lunch box. Due to the limitations of the structural design and material strength of the existing lunch box and the cost, they perform poorly when faced with these external pressures, often deformed, collapsed or even completely crushed. This not only affects the appearance and quality of the food, but also may cause the contents to leak, resulting in health hazards and economic losses.
[0024] Reference Figures 1 to 3 The present application provides a food lunch box, comprising a box cover 100 and a box body 200.
[0025] The box cover 100 is fitted at the opening of the box body 200, and the inside of the box body 200 is provided with a first support step 210 and a second support step 220. The first support step 210 is near the opening of the box body 200 and surrounds the inner wall of the box body 200, and is used to support the box cover 100. The second support step 220 is provided at the bottom of the box body 200 and surrounds the inner wall of the box body 200. The side wall of the box body 200 is provided with a plurality of trapezoidal support grooves 230, each trapezoidal support groove 230 being arranged at intervals along the length direction of the side wall of the box body 200. One end of the trapezoidal support groove 230 extends to the first support step 210, and the other end of the trapezoidal support groove 230 extends to the second support step 220. The trapezoidal support groove 230 forms a trapezoidal notch 231 at the first support step 210.
[0026] This lunch box has trapezoidal support grooves 230 arranged on the side wall of the box body 200, so that the side wall of the box body 200 forms a support structure with alternating convex and concave shapes. This makes the overall load-bearing capacity of the side wall of the lunch box stronger, and it can withstand stronger pressure during transportation, effectively preventing the lunch box from deforming, collapsing and crushing.
[0027] In some embodiments, the trapezoidal support grooves 230 at the corners of the box body 200 are arc-shaped trapezoidal support grooves 230 adapted to the shape of the corners of the box body 200, and the trapezoidal support grooves 230 on the side walls of the four sides of the box body 200 are straight-line trapezoidal support grooves 230. In this way, the corners of the entire box body 200 and the side walls of the box body 200 have good pressure-bearing performance.
[0028] In some embodiments, the opening of the box body 200 is provided with a fitting boss 240 surrounding the opening of the box body 200, and the box cover 100 is provided with a fitting groove surrounding the edge of the box cover 100, which is matched with the fitting boss 240. The box cover 100 and the box body 200 are matched through the fitting groove and the fitting boss 240 structure, which is simple and has good sealing performance.
[0029] In some embodiments, the bottom of the outer side of the fitting boss 240 is provided with a first retaining edge 250, and the edge of the box cover 100 is provided with a second retaining edge 110, which is in pressure contact with the first retaining edge 250. When the box cover 100 is matched to the box body 200, the first retaining edge 250 and the second retaining edge 110 are in close contact with each other, which further improves the sealing performance between the box body 200 and the box cover 100.
[0030] In some embodiments, the outer side wall of the fitting boss 240 is provided with a groove 260 surrounding the fitting boss 240, and the inner side wall of the fitting groove is provided with a boss surrounding the fitting groove, which is embedded in the groove 260. In this way, the fitting boss 240 and the fitting groove are matched with a groove 260 and a boss, which further improves the sealing performance between the fitting boss 240 and the fitting groove.
[0031] In some embodiments, the box cover 100 is provided with a handle 120. It is convenient for the dining personnel to pull up the box cover 100 through the handle 120.
[0032] In some embodiments, the handle 120 is arranged at one of the diagonal positions of the box cover 100.
[0033] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
