Abstract: A carbonated beverage is furnished from a source at a first pressure to a reservoir in which a quantity of the beverage is held a second pressure level that is less than the first pressure and greater than atmospheric pressure. When it is desired to dispense the carbonated beverage into a serving container, the reservoir is vented to the atmosphere so that the beverage is dispensed at substantially atmospheric pressure. The amount of carbonated beverage in the reservoir is sensed and when that amount drops below a first level, carbonated beverage is added from the source while the reservoir is vented to the atmosphere. The venting terminates when the amount of beverage in the reservoir reaches a second level. The beverage continues to flow into the reservoir thereafter for a predefined period of time causing the pressure to increase to the second pressure level.

Abstract: For a pressure reduction, an aerosol spray can filled with a compressed pressure gas requires, upstream of its spray valve (14), a pressure regulation valve (10) with a closing point (28). In known embodiment types a flow occurs around the outside of the pressure reduction valve, which requires a complicated housing structure. It is therefore proposed that the connection between the closing point (28) and the spray valve (14) take place via a central bore (58) in the piston (22) of the pressure reduction valve (10), preferably without a flow through the pressure chamber (26), but instead past the latter. The simple construction is advantageous, with which it is also possible to provide easy access to the piston (22) from the outside in order to maintain it in its opened position for easier filling under pressure.

Abstract: Disclosed are safe, easy to manufacture prismatic cells having scored regions strategically located on portions of the prismatic cell can or cell header. When they are located on the cell can, the scored regions are provided on the side of the can, rather than on the bottom of the can as in other designs. The scored region may be located on a corner of one side of the side of the cell can. Scored regions so located tend to release excess pressure over a relatively narrow and easier to control pressure range. Similar benefits can be obtained by placing the scored region on a "dished" header of a prismatic cell. Such dished header designs have a vertical lip around the perimeter of a substantially flat horizontal portion. The scoring may be provided near one of the ends of the header's substantially flat portion.

Abstract: An apparatus and method are disclosed to dispense a product out of a receptacle by moving a free-floating piston back and forth within the receptacle. Pressurized gas is used to move the piston toward the product, thereby forcing the product out of the receptacle. The pressure on the piston is released by exhausting the pressurized gas out of the receptacle through a release valve. To retract the piston away from the product, the pressurized gas is sent through a venturi that connects to the receptacle via the same aperture that is used to deliver the pressurized gas to the receptacle. The flow of pressurized gas through the venturi creates a vacuum in the receptacle that pulls the piston away from the product.
