A sealing cap fastened to a vacuum seal container and controlled to extract air out of vacuum seal container, the sealing cap including a cap body unit fastened to the vacuum seal container, and an extracting unit mounted in the cap body and controlled to extract air out of the vacuum seal container

A sealing cap fastened to a vacuum seal container and controlled to extract air out of vacuum seal container, the sealing cap including a cap body unit fastened to the vacuum seal container, and an extracting unit mounted in the cap body and controlled to extract air out of the vacuum seal container by reciprocating a control cap of the extracting unit with the hand, the air passage being automatically sealed by a flap, which is forced into the close position by atmospheric pressure, the vacuum status of the vacuum seal container being released when a control cap of the air extracting unit is turned in one direction and pressed down, the cap body having a bottom side covered with a rubber disk which fits different spout sizes and shapes, the rubber disk being secured to the cap body by a T-cap and a sponge between the T-cap and the rubber disk, the rubber disk having a convex flange of V-shaped cross section around the periphery, which prohibits the rubber disk from being forced to curve inwards and to escape out of position, the T-cap being adapted to prevent the rubber disk from being forced inwards by atmospheric pressure and to enable air to get into the inside of the container in all directions when releasing the vacuum status of the container, the T-cap and the sponge filtering and buffering air passes through to prevent powdered material from being adhered to the rubber disk in order to maintain its function of vacuum preservation.
