Abstract
[0001] The present invention relates to a safety valve for a vacuum container, and more particularly, to a safety valve for a vacuum container in which when an excessive vacuum pressure is generated within a vacuum container, the safety valve introduces external air into the vacuum container, To a safety valve for a vacuum container configured to prevent the container from being broken.
Description
[0001] The present invention relates to a safety valve for a vacuum container, and more particularly, to a safety valve for a vacuum container in which when an excessive vacuum pressure is generated within a vacuum container, the safety valve introduces external air into the vacuum container, To a safety valve for a vacuum container configured to prevent the container from being broken.
In general, food left in the home after meals is stored in a container or in a refrigerator. Even if stored in a refrigerator, food often becomes easily decayed over time.
In order to solve such a problem, the remaining food is stored in a vacuum container to prevent the food from being easily decayed. In the vacuum container, a rubber packing for sealing the gap between the lid and the container is provided, When the lid is closed, the food is cooled so that the volume of the air inside the container shrinks and the inside of the container becomes a vacuum state.
However, when vacuum pressure is excessively formed inside the vacuum container, the container or lid formed of a thin metal is distorted. In the case of a lid or a container formed of a glass material, the vacuum is sometimes broken by the vacuum pressure inside the container do.
Particularly, when the lid or the container is formed of glass, the glass is broken by the vacuum pressure inside the container, so that the fragments may protrude in all directions and cause a safety accident.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a safety valve in which when an excessive vacuum pressure is generated in a vacuum chamber, It is an object of the present invention to provide a safety valve for a vacuum container which can prevent the container from being broken by adjusting the vacuum pressure.
According to an aspect of the present invention, there is provided a safety valve for a vacuum container, including: a hole formed in a lid or a container for communicating the inside and the outside of the container; The

When the vacuum pressure inside the vacuum container is below the prescribed pressure, the safety valve functions as a vacuum holding valve. When excessive vacuum pressure is generated in the vacuum chamber above the specified pressure, the safety valve is automatically opened, Air is introduced into the interior of the vacuum container to adjust the inside of the vacuum container to a pressure equal to or lower than the specified pressure, thereby preventing the container from being damaged.
