Description

Technical Field

[0001] This application relates to the technical field of tableware, and particularly to a lunch box lid and a lunch box. Background Art

[0002] In the fields of takeaway and food packaging, the design of lunch boxes and their lids is crucial, especially for maintaining the quality and safety of food during transportation. To prevent high-temperature food from scalding the lunch box, existing lunch box lids usually have ventilation holes, which help release heat and prevent the lunch box from deforming or cracking due to the high temperature and pressure generated by food in a closed space. However, when the lunch box contains liquid food such as soup, the ventilation hole design has obvious defects: during transportation, the soup is likely to spill out through the ventilation holes, causing food waste and pollution. This not only affects the user's dining experience but also may lead to the pollution of the outer packaging and inconvenience in carrying. To solve this problem, existing lunch boxes are provided with a ventilation hole cover that is buckled outside the ventilation hole at the position of the ventilation hole. During transportation, when the pressure inside the lunch box becomes high due to high temperature, the ventilation hole cover is opened for ventilation, and then covered after ventilation. On the one hand, it plays a role in ventilation, and on the other hand, it prevents the soup from spilling out through the ventilation holes. However, when the soup leaks from the ventilation hole in this structure of lunch box lid, it will remain between the ventilation hole cover and the ventilation hole. When the diner opens the ventilation hole cover during dining, the soup remaining between the ventilation hole and the ventilation hole cover will spill out, causing discomfort to the diner. Summary of the Invention

[0003] This application aims to solve at least one of the above technical problems in the prior art to some extent. For this purpose, an embodiment of this application provides a lunch box lid and a lunch box, in which no soup will remain between the ventilation hole cover and the ventilation hole, and there will be no problem of soup spilling when the diner opens the ventilation hole, making it cleaner and more hygienic to use.

[0004] A lunch box lid includes:

[0005] A lid body, on which a concave flow-accumulating structure is provided, a ventilation hole is opened at the converging place of the flow-accumulating structure, and an annular boss surrounding the flow-accumulating structure is provided on the lid body;

[0024] In the field of takeaway and food packaging, the design of food containers and their lids is crucial, especially for maintaining the quality and safety of food during transportation. To prevent hot food from damaging the food container, existing food container lids usually have ventilation holes, which help release heat and avoid deformation or rupture of the food container caused by the high temperature and pressure generated by the food in a closed space. However, when the food container contains liquid food such as soup, the ventilation hole design has obvious defects: during transportation, the soup is likely to spill out through the ventilation holes, resulting in food waste and pollution. This not only affects the user's dining experience but also may cause pollution of the outer packaging and inconvenience in carrying. To solve this problem, existing food containers are provided with a ventilation hole cover that is buckled outside the ventilation holes at the position of the ventilation holes. During transportation, when the pressure inside the food container becomes high due to high temperature, the ventilation hole cover is opened for ventilation, and then covered again. On the one hand, it plays a role in ventilation, and on the other hand, it prevents the soup from spilling out through the ventilation holes. However, when the soup leaks out from the ventilation holes in this type of food container lid, it will remain between the ventilation hole cover and the ventilation holes. When the diner opens the ventilation hole cover during dining, the soup remaining between the ventilation holes and the ventilation hole cover will spill out, causing discomfort to the diner.

[0025] Referring to Figure 1 、 Figure 2 , the present application provides a food container lid, which includes a lid body 100 and a ventilation hole cover 200.

[0026] An inwardly concave flow-accumulating structure 121 is provided on the lid body 100, a ventilation hole 122 is opened at the converging portion of the flow-accumulating structure 121, an annular boss 125 is provided on the lid body 100 around the flow-accumulating structure 121, and the ventilation hole cover 200 is fitted on the annular boss 125.

[0027] After this food container lid is covered on the food container, when heat needs to be released, the ventilation hole cover 200 is opened. At this time, the hot air in the food container will be released from the ventilation hole 122. When the ventilation hole cover 200 is covered, even if the soup in the food container leaks out from the ventilation hole 122 during transportation, since the ventilation hole 122 is opened at the converging portion of the flow-accumulating structure 121, the soup will also be collected into the ventilation hole 122 through the flow-accumulating structure 121 and flow back into the food container. Therefore, no soup will remain between the ventilation hole cover 200 and the ventilation hole 122, and there will be no problem of soup spilling when the diner opens the ventilation hole 122, making it cleaner and more hygienic to use.

[0028] In some embodiments, the flow-accumulating structure 121 is a conical groove, and the ventilation hole 122 is opened at the conical end of the conical groove. The function of flow accumulation is realized by the conical groove provided on the lid body 100.

[0029] Of course, in addition to setting the conical grooves, the liquid-converging structure 121 can also be provided with structures such as concave triangular grooves, as long as it can converge the liquid to the air-permeable holes 122.

[0030] In some embodiments, a baffle 123 is provided on the inner wall of the conical groove. The baffle 123 is spirally arranged along the conical groove with the air-permeable hole 122 as the center. The baffle 123 can play a role in blocking. By lengthening the flow path of the soup in the conical groove after flowing out from the air-permeable hole 122, the effect of reducing the spreading area of the soup in the conical groove can be achieved, and the pollution area of the inside of the conical groove by the soup can be reduced.

[0031] In some embodiments, the lid 100 includes a lid body 110 and a pressure-bearing boss 120. The pressure-bearing boss 120 protrudes in the middle of the lid body 110. The edge of the pressure-bearing boss 120 is bent downward to be connected to the lid body 110, and the edge of the pressure-bearing boss 120 is a wavy structure 124. The pressure-bearing boss 120 plays a role in bearing pressure, making the pressure-bearing performance of the lunch box lid better. By setting the wavy structure 124, the pressure-bearing performance of the pressure-bearing boss 120 can be effectively improved, making the pressure-bearing capacity of the lunch box lid stronger.

[0032] In some embodiments, the liquid-converging structure 121 is provided in the middle of the pressure-bearing boss 120.

[0033] In some embodiments, a first handle 111 is provided on the side of the lid 100. It is convenient to lift the lid 100 from the lunch box.

[0034] In some embodiments, a second handle 210 is provided on the side of the air-permeable hole lid 200. It is convenient to lift the air-permeable hole lid 200 from the annular boss 125.

[0035] Refer to Figure 3 , the present application also provides a lunch box, including a box body 300 and any one of the above lunch box lids, and the lunch box lid is matched with the box body 300.
