Description

Box door sealing structure and container Technical Field The present utility model relates generally to the field of containers, and more particularly to a door seal structure and a container. Background In transporting precision equipment or precision instruments such as satellite equipment, lithography machines, etc. by using containers, it is common to fill the containers with an inert gas such as, for example, nitrogen gas, etc. to protect the precision equipment or precision instruments. Therefore, the box body has strict air tightness performance parameter requirements, and the pressure drop of the gas pressure in the box body within 24 hours is generally required to be not more than 5% -10%.
