Abstract: An adjustable sealing device for a storage container is disclosed that has a compressible sealing ball to provide a seal with the inner surface of containers having a variety of sizes and shapes. The device's valve ball for its vent is normally biased closed by a tensioner, and is selectively opened by a flexible lead. The lead passes through a container lid and compression washer(s) located between the sealing ball and lid. To insert the sealing ball into the container the lead is tensioned, to orient the longitudinal axis of the washer(s) perpendicular to the lid and sealing ball, so that pressure on the lid will be transmitted to the sealing ball through the compression washer(s). Releasing the lead's tension enables the lid to be placed on the container, and the lead and compression washers to be compactly draped over the sealing ball inside of the container.

Abstract: A container is provided having corresponding shells that mate together about a joint to create an enclosed airtight container. A valve seat is formed on the exterior of a shell adjacent the joint. The valve seat has an opening in communication with the container interior. A latch assembly is used to secure the shells in a closed position. The assembly includes a latch body which is attached to a shell by a hinge fastener close to said joint. The inside face of the latch body is provided with a valve gasket having a curved outer face that is aligned and sealingly engageable with the valve seat. When the latch is closed, the gasket will seal against the valve seat. When the latch is dislodged from its connection to the other shell, the gasket will be simultaneously removed from the valve seat and allow air to flow through the opening. This action permits equalization of any pressure differentials between ambient pressure and the pressure in the container interior.

Abstract: Disclosed is a bottle cap for vacuum preservation, comprising a cap main body consisting of a cylindrical cap tube inserted in a vessel, and a holder part extended from an end, located at a vessel inlet, of the cap tube; a piston airtightly inserted in the cap main body and axially sliding along the cap main body to release air in the vessel; and a valve member positioned in an end, located in the vessel, of the cap main body. The holder part is bent in such a way that its bent part is parallel to the cap tube, and the valve member opens and closes an air hole for introducing and releasing air in the vessel according to movement of the piston. The bottle cap can avoid disadvantages of deterioration of contents in the vessel, inconvenience of separately storing a pump, and loss of the pump. Furthermore, the vessel is readily vacuumized using the bottle cap.

Abstract: The invention relates to a closing cap (10) for the fixed tubing of a motor vehicle radiator, comprising an inner part (14) with a flow connection means between the inside and the outside of the container, as well as a distributing mechanism for freeing and closing the flow connection means. A valve body (22) of the distributing mechanism (11), which can be reciprocated, is compressed under pre-stress towards the inside of the container against a sealing seat (21) at the inner part (14) of the cap, so that said valve body can be lifted from said sealing seat (21) when a threshold value of the pressure inside the container is exceeded.

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. With a downward movement of the upper cylindrical member, the upper space expands and draws air inside of a bottle, and with an upward movement thereof, the air introduced into the upper space is vented outside. 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.
