     FIELD OF THE INVENTION 
     The present invention relates to apparatus and methods for dispensing products from a product container, including a bag-on-valve (BOV) container or an airless dispensing system, such as, but not limited to, a collapsible bag-in-bottle container or a follower piston container. 
     BACKGROUND 
     Bag-on-Valve (BOV) is a packaging technology that is used for pharmaceutical, over the counter, food and healthcare products. A conventional BOV system consists of a rolled-up multi-layered flexible pouch attached to an aerosol valve. In the production of a BOV container with product, compressed air or nitrogen is injected into an empty canister, and a cup having an aerosol valve assembly with the BOV bag attached, is crimped onto the container. The product to be dispensed is forced through the aerosol valve stem to fill the BOV bag. Finally, the actuator and cap are put in place. 
     An airless dispensing system includes, inter alia, an airless piston package or aluminum pouch airless package. An airless dispenser system includes a pump assembly includes a pump mechanism with an inlet valve that is configured to efficiently pump viscous fluids and that is able to be pre-primed when the pump mechanism is attached to a container. In one form, the inlet valve includes a seal member that seals an inlet port of the pump and an outer support member that secures the inlet valve to the rest of the pump mechanism. Two or more legs generally extend in a circumferential direction between the support member and the seal member in order to create a large flow opening for fluid flow through the inlet valve when opened and to rapidly close the inlet valve. The pump mechanism further includes an outlet valve that is configured to draw fluid back from a nozzle of the pump after dispensing in order to minimize build up around the nozzle. 
     Conventional airless type pumps are advantageous as some food products deteriorate when placed in contact with air, thus it is important to prevent air from entering the package when dispensing the product. In typical dispensing pump applications, air is allowed to enter the container via a venting path in order to equalize the pressure inside the pack as product is dispensed. Were this not the case, the container would progressively collapse or, in the case of rigid containers, the increasing vacuum in the container would exceed the ability of the dispensing pump to draw product out of the container. 
     In airless type dispensing systems, there are two common ways to evacuate the container holding the product, either by using a follower piston type design or a collapsible bag type design. In the follower piston type design, a rigid container, usually cylindrical or oval in form, has a follower piston that progressively reduces the container volume as product is drawn out by the dispensing pump. With the collapsible type design, a collapsing bag is attached to the dispensing pump, which progressively collapses as the contents are removed. 
     What is desired is a dispenser to which a filled BOV container or an airless type dispensing container can be interchangeably coupled, the dispenser having a mixing valve or chamber for mixing product from the product container with a product such as water, or alternatively, a bypass conduit for bypassing the mixing valve or chamber so as to allow only product from the BOV container or an airless type dispensing container to be dispensed from the dispenser. 
     SUMMARY 
     A dispenser platform for receiving a bag on valve (BOV) container or an airless type dispensing container (“product container” hereinafter referring to either of the foregoing), having a casino, wholly or partially encasing a control panel coupled a control module and a product container receptacle having a product container coupling assembly. The product container coupling assembly includes a first product supply conduit configured to receive a barrel of a product container. A second product supply conduit couples to a reservoir or to a supply of a second product, such as water, which may be carbonated or processed with carbon. The product container holds a first product, such as concentrated coffee, concentrated tea, concentrated flavored drink, flavored syrup (e.g., cola) or concentrated juice, etc. A pump assembly having a pump inlet and pump outlet and a pump activation assembly is coupled to the control module and interposed between the second product supply conduit and a mixing chamber. In the mixing chamber, the first product and second product are combined. The first product and second product are introduced into the mixing chamber via one or more valve assemblies. A heating and/or cooling assembly responsively coupled to the control panel via the control module is configured and controlled to heat or cool the first product, second product or both of them, either prior to or after the mixing chamber. The product is then dispensed at a dispensing valve. 
     In an alternative embodiment, a carbonator comprising a carbon dioxide (CO2) tank is coupled to a conduit in direct or indirect communication with the second product supply conduit, which is water in this embodiment. The carbonator carbonates the water. The carbonated water (mixed CO2 and first product) can be introduced with flavored syrup at the dispensing valve (post-mix) or prior thereto, e.g., at the mixing chamber (pre-mix). 
     A filter assembly is interposed to filter the first product, second product of the combined products. The combined first product and second product are dispensed from the dispenser platform via a dispenser platform outlet. In a further embodiment, a bypass conduit is provided for bypassing the mixing valve or chamber so as to allow only product from the product container to be dispensed from the dispenser. 
     Although the preferred invention is described as being configured to receive, combine and dispense two products, the dispenser platform can be configured to receive, combine and dispense any desired number of products as long as one of the products is dispensed from either a bag on valve (BOV) container or an airless type dispensing container. Further, subcomponents of the dispenser platform component of the invention, such as the valve assemblies, filter assemblies, heating/cooling assemblies and pump assemblies can be arranged or configured in any desired serial, mesh or parallel arrangement as desired, and all such embodiments and arrangements are claimed by, and considered within the scope of this invention.

The product container coupling assembly includes a first product supply conduit configured to receive a barrel of a product container. A second product supply conduit couples to a reservoir or to a supply of a second product, such as water. The product container holds a first product, such as concentrated coffee, concentrated tea, concentrated flavored drink, flavored syrup (e.g., cola) or concentrated juice, etc. A pump assembly having a pump inlet and pump outlet and a pump activation assembly is coupled to the control module and interposed between the second product supply conduit and a mixing chamber. In the mixing chamber, the first product and second product are combined. The first product and second product are introduced into the mixing chamber via one or more valve assemblies. A heating and/or cooling assembly responsively coupled to control panel via the control module is configured and controlled to heat or cool the first product, second product or both of them, either prior to or after the mixing chamber. 
     In an alternative embodiment, a carbonator comprising a carbon dioxide (CO2) tank is coupled to a conduit in direct or indirect communication with the second product supply conduit, which is water in this embodiment. The carbonator carbonates the water. The carbonated water (mixed CO2 and first product) can be introduced with flavored syrup at the dispensing valve (post-mix) or prior thereto, e.g., at the mixing chamber (pre-mix). 
     A filter assembly is interposed to filter the first product, second product of the combined products. The combined first product and second product are dispensed from the dispenser platform via a dispenser platform outlet or dispensing valve.
