Seal valve assembly for vacuuming bottles

Abstract

A vacuum bottle includes a bottle with a cap mounted on a top opening of the bottle, the cap having pipes and vacuuming members connected thereto so as to vacuum the interior of the bottle. A through hole and a release hole are respectively defined through the cap. A sleeve, a connection member and a bellow member are respectively received in the through hole. When vacuuming the interior of the bottle, the bellow member is compressed to lift the sleeve out from the through hole. When the vacuum status is released, the bellow member is released and the sleeve is merged in the through hole. By the movement of the sleeve, users are acknowledged the status in the bottle. A valve assembly is connected to the pipes in the cap so as to prevent air from entering into the bottle.
