Abstract

The invention belongs to the technical field of daily necessities, and relates to a lunch box with ventilation holes and noise reduction, which is characterized in that it includes a lunch box, a sealing ring, a lunch box cover and a buckle; the lunch box cover is detachably connected to the lunch box through the buckle; the buckle is uniform Hinged to the outer side of the lunch box cover; the outer ring and the inner ring set at one end of the lunch box cover form an annular groove for placing the sealing ring. The sealing ring is uniformly provided with a first air hole, and the annular groove is evenly provided with a second air hole. The inner wall of the second air hole located on the outer ring is provided with a protrusion, and the number of the first air hole is the same as that of the second air hole; the buckle is provided with a plug on the side facing the lid of the lunch box, and the plug corresponds to the position of the second air hole There is a plug groove on the plug, and the protrusion is matched with the plug groove; the present invention has exquisite design, simple structure, and saves materials. When buckling, the ventilation hole can be opened and closed, so that the air pressure inside the lunch box is the same as that of the outside world, and it is easy to open.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a lunch box with ventilation holes and noise reduction. Background technique [0002] Most people, such as students, workers, and company employees, dine in group restaurants, and most restaurants provide recycled tableware, which poses health risks in terms of sanitation. As people's awareness of health and environmental protection becomes stronger and stronger, many people choose to bring their own tableware when dining, but the lunch boxes currently on the market have the following disadvantages: 1. There is no ventilation hole, and the general meals have a certain Heat, after putting the lid on the lunch box for a period of time, the food in the lunch box will cool down, causing the air pressure inside the lunch box to drop, making it difficult to open the lunch box. During the fastening process, the buckle will directly hit the side wall of the lunch b...
