A pump and stopper combination for vacuum or pressure sealing a container. The stopper has a pour opening and a one-way valve movable between an operative position to permit one-way flow of fluid into or out of the container when the pour opening is in the closed position, and an inoperative position when the pour opening is in the open position. A vacuum/pressure pump that connects to the stopper includes a drive adapted to convert rotational movement of a motor to reciprocating motion of a pump piston in a chamber, and one-way pump valves mounted in a selectable flow control member. The selectable flow control member is movable between pressure and vacuum positions to permit passage of fluid only into or out of the pump chamber. The pump also includes an indicator for indicating when a desired level of vacuum or pressure has been reached The pump may be incorporated into a container lid.

Thus, having described the invention, what is claimed is: 1. A stopper for contacting and sealing with an opening in a container comprising a collar for removable sealing engagement with a pump and a portion extending from a lower end of the collar for insertion into the container opening, the stopper having a pour opening for accessing contents in the container, the pour opening being movable between open and closed positions, and a one-way valve movably disposed in the stopper between an operative position to permit one-way flow of fluid into or out of the container when the pour opening is in the closed position, and an inoperative position when the pour opening is in the open position. 2. The stopper of claim 1 wherein the one-way valve is movable to a first operative position when the pour opening is in the closed position to permit one-way flow of fluid into the container, and to a second operative position when the pour opening is in the closed position to permit one-way flow of fluid out of the container. 3. The stopper of claim 1 wherein the stopper includes a rotatable ball valve body having the pour opening disposed therein in a first direction, and the one-way valve disposed therein in a second direction, the ball valve body being movable between the first and second directions to open and close the pour opening, and respectively render inoperative and operative the one-way valve. 4. The stopper of claim 1 wherein the one-way valve comprises a valve seat having an opening therein; and a valve diaphragm having a sealing member supported by flexible arms in a normally biased position against and sealing the valve seat opening, wherein when a fluid is forced in a first direction through the valve seat opening against the sealing member, the arms flex and move the sealing member away from the valve seat opening to permit fluid flow out of the valve seat opening, and when the fluid is forced in a direction opposite the first direction, the arms do not flex and the sealing member remains in the normally biased position against and sealing the valve seat opening to restrict fluid flow. 5. The stopper of claim 1 wherein the stopper further includes a central pour opening for pouring out the contents of the container when the container is tipped from an upright position, and at least one parallel annular passageway surrounding the central pour opening to permit air to flow into the container to release back pressure. 6. The stopper of claim 1 in combination with a container having an opening therein, the stopper lower portion being inserted into the container opening. 7. The stopper of claim 1 in combination with a container having an opening therein and a pump, the stopper lower portion being inserted into the container opening and the stopper collar being in removable sealing engagement with the pump. 8. A stopper for contacting and sealing with an opening in a container, the stopper having an opening therethrough between the container interior and exterior including a central pour opening for pouring out the contents of the container when the container is tipped from an upright position, and at least one parallel passageway adjacent the central pour opening to permit air to flow into the container to release back pressure, and a one-way valve disposed in the opening, the one-way valve comprising: a valve seat having an opening therein; and a valve diaphragm having a sealing member supported by flexible arms in a normally biased position against and sealing the valve seat opening, wherein when a fluid is forced in a first direction through the valve seat opening against the sealing member, the arms flex and move the sealing member away from the valve seat opening to permit fluid flow out of the valve seat opening, and when the fluid is forced in a direction opposite the first direction, the arms do not flex and the sealing member remains in the normally biased position against and sealing the valve seat opening to restrict fluid flow. 9. The stopper of claim 8 wherein the sealing member comprises a bulb or cap suspended by a plurality of radially extending arms attached to the valve seat outward of the valve seat opening. 10. The stopper of claim 8 further including a selectable flow control member in the stopper opening having at least one passage therein and movable between pressure and vacuum positions, the one-way valve being disposed in the selectable flow control member passage, the selectable flow control member being rotatable: i) in the pressure position, to place the one-way valve in an orientation to permit passage of fluid only into the container interior, and ii) in the vacuum position, to place the one-way valve in an orientation to permit passage of fluid only out of the container interior.
