Alternatively, the valve may release both fluids when open.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
327 words
Valve for simultaneously dispensing a plurality of fluids maintained under pressure, said valve comprising in combination: a cup defining a central chamber and adapted to be secured beneath the cap of an outer container, said chamber being formed with at least one upper port for communication with a first container and a lower port for communication with a second container; stationary sealing means closing the top of said chamber; a spout extending through said sealing means into said chamber and slidable therein between an upper ''''closed'''' position, an intermediate ''''cleaning'''' position and a lower ''''open'''' position, said spout having a central longitudinal channel blocked near its midpoint, at least one upper port above the point at which it is blocked and a lower port below that point, resilient means biasing said spout toward its closed position; a slidable sealing member encircling said spout within said chamber and slidable relative to said cup between an upper position closing the upper port in said cup and a lower position clear of the upper port in said cup, and abutment means on said spout positioned to hold said slidable sealing means in its upper position when said spout is in its closed position and move said slidable sealing means into its lower position when said spout is moved to its open position, said spout being movable in said slidable sealing member so that the lower port in said spout is clear of said slidable sealing member when said spout is in its intermediate cleaning position, but blocked by said sealing member when said spout is in its open position, thereby providing an open passage leading from the lower port in said cup through both ports in said spout to the outer end of said spout when said spout is in its cleaning position, and an open passageway leading from the peripheral port in said cup through the upper port in said spout when said valve is in its open position.
Claim 2
Dependent Claim

Valve for simultaneously dispensing a plurality of fluids maintained under pressure, said valve comprising in combination: a cup defining a central chamber and adapted to be secured beneath the cap of an outer container, said chamber being formed with at least one upper port for communication with a first container and a lower port for communication with a second container; stationary sealing means closing the top of said chamber; a spout extending through said sealing means into said chamber and slidable therein between an upper ''''closed'''' position, an intermediate ''''cleaning'''' position and a lower ''''open'''' position, said spout having a central longitudinal channel blocked near its midpoint, at least one upper port above the point at which it is blocked and a lower port below that point, resilient means biasing said spout toward its closed position; a slidable sealing member encircling said spout within said chamber and slidable relative to said cup between an upper position closing the upper port in said cup and a lower position clear of the upper port in said cup, and abutment means on said spout positioned to hold said slidable sealing means in its upper position when said spout is in its closed position and move said slidable sealing means into its lower position when said spout is moved to its open position, said spout being movable in said slidable sealing member so that the lower port in said spout is clear of said slidable sealing member when said spout is in its intermediate cleaning position, but blocked by said sealing member when said spout is in its open position, thereby providing an open passage leading from the lower port in said cup through both ports in said spout to the outer end of said spout when said spout is in its cleaning position, and an open passageway leading from the peripheral port in said cup through the upper port in said spout when said valve is in its open position.
Claim 3
Dependent Claim
53 words
In combination, a valve as claimed in claim 1, an outer jacket closed by said valve, said outer jacket being in communication with the lower port in said cup, and holding a pressurizing fluid, and an inner container holding a fluid to be dispensed and connected to each upper port in said cup.
Claim 4
Dependent Claim
49 words
A valve as claimed in claim 1 in which an open passage maintains constant communication between those portions of said chamber on opposite sides of said sliding sealing member, so that fluid from the lower port in said cup is dispensed whenever said spout is in its open position.
Claim 5
Dependent Claim
54 words
A valve as claimed in claim 1 in which said stationary sealing means is a resilient disc having a domed central portion encircling said spout, whereby excessive pressure beneath said sealing member will force the walls of said dome away from said spout to prOvide a channel therebetween for the relief of said pressure.
