Abstract: A vacuum apparatus for easily forming a vacuum in any bottle, container or the like and for providing a stable sealing. A lower cylindrical member together with a disc member forms a space portion in which a vacuum or an atmospheric pressure is applied, and the lower portion of an upper cylindrical member is inserted in the space portion and divides the space portion into upper and lower spaces.

At this time, a check valve is selectively opened and closed and is operated by a pressure difference applied thereon. By repetitive reciprocating movement of the upper cylindrical member, a high vacuum is formed in the bottle and is sealed by the check valve. The apparatus is adaptable in a vacuum bottle, a medical suction instrument or the like.

Additionally, pressure increase within the container is directed to increase sealing force of seals positioned on the piston and thus prevents the release of pressure from the container, allowing the closure to be used for carbonated beverages. The piston is displaced from the closed position, even when the container internal pressure is increased, by the user sucking on a mouth piece.

Abstract: A cap system for use with a beverage container that has automatic opening and closing capability is provided. A buoyant sliding cover is maintained partially within a casing or housing device in the cap and partially within the container itself.
