Wine stop pump

Abstract

A cap device for capping an open wine bottle includes a base with a lower cylindrical portion that defines an interior space. The lower cylindrical portion engages the interior of the wine bottle. A pumping element engages an upper cylindrical portion of the base to define an interior portion in communication with the interior space. A first valve assembly is disposed in the lower cylindrical portion and is in communication with the interior space and the interior of the wine bottle. The first valve assembly is movable between an open and closed position for pulling air from the wine bottle. A second valve assembly is disposed in the upper cylindrical portion of the base and is in communication with the interior portion and the atmosphere. The second valve assembly is movable between an open and closed position for pushing air from the interior portion to the atmosphere.

1 . A cap device for capping an open wine bottle to preserve its contents for later use comprising:
 a base having a flat disk portion and a lower cylindrical portion extending axially from said flat disk portion to engage the interior of the neck of the open wine bottle, said lower cylindrical portion defining an interior space therewithin;   said base including an upper cylindrical portion having a cylindrical wall extending axially from the periphery of said flat disk portion in a direction opposite of said lower cylindrical portion and to an upper cylindrical surface;   a pumping element for mating with said upper cylindrical surface of said upper cylindrical portion to define an interior portion in communication with said interior space;   a first valve assembly disposed in said lower cylindrical portion of said base and in communication with said interior space and the interior of the wine bottle, said first valve assembly being movable between an open and closed position for pulling air from the interior of the wine bottle while allowing no air to seep back into the wine bottle from said interior space; and   a second valve assembly disposed in said upper cylindrical portion of said base and in communication with said interior portion and the atmosphere, said second valve assembly being movable between an open and closed position for pushing air from said interior portion to the atmosphere while allowing no air to seep back into said interior portion from the atmosphere.   
   
   
       2 . The cap device as set forth in  claim 1  further including a spring disposed between said pumping element and said flat disk portion for biasing said pumping element axially away from said flat disk portion of said base. 
   
   
       3 . The cap device as set forth in  claim 1  wherein said pumping element includes a top portion and an axially extending wall portion to engage said upper cylindrical surface of said upper cylindrical portion, said wall portion having a plurality of bellows for allowing said pumping element to move axially upward and downward. 
   
   
       4 . The cap device as set forth in  claim 1  wherein each of said valve assemblies include a first housing, a second housing secured to said first housing to define an inner space and a silicon valve disposed in said inner space, said first housing defining an opening and said silicon valve having a seating portion that extends radially outward to an outer portion for being pressed against said opening for placing said valve assembly in said closed position. 
   
   
       5 . The cap device as set forth in  claim 4  wherein said outer portion of said silicone valve is flexible to flex toward the second housing portion for placing said valve assembly in said open position. 
   
   
       6 . The cap device as set forth in  claim 1  wherein both said first and second valve assemblies are in said closed position. 
   
   
       7 . The cap device as set forth in  claim 6  wherein said first valve assembly is in said closed position and said second valve assembly is in said open position and air is pushed from said interior portion to the atmosphere as a top portion of said pumping element is engaged and pressed toward said base. 
   
   
       8 . The cap device as set forth in  claim 6  wherein said second valve assembly is in the closed position and said first valve assembly is in an open position and air is pulled from the interior of the wine bottle to said interior space of said base as a top portion of said pumping element is biased away from said base. 
   
   
       9 . The cap device as set forth in  claim 8  further including a spring disposed between said pumping element and said flat disk portion for biasing said pumping element axially away from said flat disk portion of said base. 
   
   
       10 . A cap device for capping an open wine bottle to preserve its contents for later use comprising:
 a base having a flat disk portion and a lower cylindrical portion extending axially from said flat disk portion to engage the interior of the neck of the open wine bottle, said lower cylindrical portion defining an interior space therewithin;   said base including an upper cylindrical portion having a cylindrical wall extending axially from the periphery of said flat disk portion in a direction opposite of said lower cylindrical portion and to an upper cylindrical surface;   a pumping element having a top portion and an axially extending wall portion to engage said upper cylindrical surface of said upper cylindrical portion to define an interior portion in communication with said interior space, said wall portion including a plurality of bellows for allowing said pumping element to move axially upward and downward;   a spring disposed between said pumping element and said flat disk portion for biasing said pumping element axially away from said flat disk portion of said base;   a first valve assembly disposed in said lower cylindrical portion of said base and in communication with said interior space and the interior of the wine bottle, said first valve assembly being movable between an open and closed position for pulling air from the interior of the wine bottle while allowing no air to seep back into the wine bottle from said interior space; and   a second valve assembly disposed in said upper cylindrical portion of said base and in communication with said interior portion and the atmosphere, said second valve assembly being movable between an open and closed position for pushing air from said interior portion to the atmosphere while allowing no air to seep back into said interior portion from the atmosphere.   
   
   
       11 . The cap device as set forth in  claim 10  wherein each of said valve assemblies include a first housing, a second housing secured to said first housing to define an inner space and a silicon valve disposed in said inner space, said first housing defining an opening and said silicon valve having a seating portion that extends radially outward to an outer portion for being pressed against said opening for placing said valve assembly in said closed position. 
   
   
       12 . The cap device as set forth in  claim 11  wherein said outer portion of said silicone valve is flexible to flex toward the second housing portion for placing said valve assembly in said open position. 
   
   
       13 . The cap device as set forth in  claim 10  wherein both said first and second valve assemblies are in said closed position. 
   
   
       14 . The cap device as set forth in  claim 13  wherein said first valve assembly is in said closed position and said second valve assembly is in said open position and air is pushed from said interior portion to the atmosphere as a top portion of said pumping element is engaged and pressed toward said base. 
   
   
       15 . The cap device as set forth in  claim 13  wherein said second valve assembly is in the closed position and said first valve assembly is in an open position and air is pulled from the interior of the wine bottle to said interior space of said base as a top portion of said pumping element is biased away from said base.
