Description

Technical Field

[0001] The utility model relates to the technical field of catering supplies, in particular to a leak-proof bowl cover for a disposable plastic lunch box. Background Art

[0002] Disposable plastic lunch boxes are a common type of lunch box used in takeout and fast food restaurants. They are usually made of plastic materials such as polystyrene or polypropylene. They are heat-resistant and corrosion-resistant and can withstand high-temperature food and acidic and alkaline food. These lunch boxes are usually round or rectangular in appearance and are mainly composed of a bowl body and a bowl cover. The bowl body is used to hold food, and the bowl cover closes the bowl body to seal the food. Some lunch boxes also have partitions to facilitate the isolation of different types of food. They are easy to use. Just put the food in the bowl body and cover it with the bowl cover. After strict sanitary treatment, they do not contain harmful substances and have certain antibacterial functions to ensure the hygiene and safety of food. Since lunch boxes are prone to spillage when holding soup and food, it is necessary to close and seal the lunch boxes to prevent leakage.

[0003] In the related art, during the use of the lunch box, a plastic wrap is generally wrapped around the outer side of the closed bowl cover and the bowl body to seal and prevent leakage between the bowl body and the bowl cover, so that the lunch box can be used.

[0004] However, during the current use of the lunch box, due to the leak-proof method of wrapping the plastic wrap, when the soup flows to the gap between the bowl body and the bowl cover due to the impact of bumps and shakes, it is still easy to leak, resulting in the bowl cover and the bowl body being unable to effectively contain the soup and food and prevent leakage, thus affecting the leak-proof effect of the lunch box.
