Abstract: A vacuum container includes an automatic suction structure mounted in a cap of the vacuum container for drawing air out of the hollow interior of a container body. The suction structure includes an electric suction device, a detecting device, a monitoring device, and a releasing device. The suction device is used to create a vacuum in the hollow interior of the container body. The detecting device is used to detect the leak between the cap and the container body. The monitoring device is intended to monitor the vacuum state in the hollow interior of the container body. The releasing device is used to enable the cap and the container body to be separated from each other.

Abstract: A vacuum extractor mounted in an one-way valve in a lid of a container body of a vacuum container and adapted to extract air out of the vacuum container, including an extraction pump mounted in the one-way valve and driven to draw air away from the container body, a motor mounted in the lid, a reciprocating mechanism driven by the motor to reciprocate the extraction pump, causing it to draw air away from the container body, and a vacuum a detector mounted in the lid and adapted to detect the pressure of air in the container body, the vacuum detector connecting a power source to the motor when the pressure of air in the container body surpasses a predetermined high value, and cutting off the power source from the motor when the pressure of air in the container body drops below a predetermined low value.
