A beverage dispensing system is disclosed which uses throw-away plastic packages in which beverage concentrate is contained. The package comprises a body and an integral valve. The valve has a sleeve in which is contained a rotary barrel. The barrel defines two sub-chambers. As the barrel is turned by a drive of the machine, the valve is positioned so that one of the sub-chambers dispenses its contents into a drinking vessel, while the other refills and vice versa. As long as concentrate is being dispensed, diluent is also being dispensed into the vessel to form the final beverage.

A container for dispensing metered doses of liquid comprising: (a) a container body for holding a bulk supply of liquid which has an outlet at the top thereof and which is for use in an inverted position; (b) valve means integral with the container body; (c) a dispensing outlet in said valve means; (d) said valve means comprising a cylindrical outer sleeve which lies with its axis horizontal when the container is in use; (e) a sleeve inlet in said sleeve in communication with said outlet from said container body; (f) a cylindrical valve barrel rotatably positioned in said sleeve; (g) a partition in said cylindrical valve barrel, which splits said barrel into first and second metering chambers; (h) first and second inlet ports in said valve barrel located in a first vertical plane with said sleeve inlet, said first and second ports extending circumferentially of the valve barrel such that ends thereof lie closely adjacent the partition and such that the circumferential spacing between adjacent ends of said ports in less than the circumferential extent of the sleeve inlet; (i) first and second chamber outlets in said valve barrel which are in a second vertical plane spaced axially of the sleeve from said first vertical plane; (j) a sleeve outlet lying in said vertical plane; (k) first and second venting outlets in said valve barrel in a third vertical plane axially spaced from the first and second vertical planes, for venting of air from said chambers; (l) a venting outlet in said sleeve in said third vertical plane; and (m) the container being adapted for use so that the valve barrel can be turned in the sleeve so as to have three operational positions, including a first position in which two adjacent ends of the valve barrel inlet ports communicate with the sleeve inlet and the interior of the container body for filling of the first and second chambers simultaneously, in which position the venting outlet in the sleeve and the sleeve outlet are blocked; a second position in which the inlet port of the first chamber communicates with the sleeve inlet and the interior of the container body for filling of the first chamber with liquid, the second venting outlet which is associated with the second chamber being in communication with the venting outlet of the sleeve, while the second chamber outlet is in communication with the sleeve outlet for the discharge of the contents of the second chamber from the valve means; and a third position which is similar to the second position except that the second chamber fills while the first chamber drains, the container body and valve means therefore providing that at all times the bulk supply of liquid is in communication with and is always filling at least one of the first and second chambers.
