A container for dispensing a concentrate at a predetermined flow rate includes a first container part for containing a volume of the concentrate terminating in a first valve part in communication with the volume, a second container part having a second mating valve part therein and having an outlet opening, the second container part movable with respect to the first container part to selectively move the first and second valve parts together and apart by a preselected amount to control the flow of the concentrate from said first part, through the valve parts and out the outlet, tabs on the outside of the first and second parts for effecting movement of the first and second parts with respect to each other, and a tube to permit application of a controlled pressure to the volume in the container.

A container for dispensing a concentrate through air to a receptacle at a fixed and predetermined flow rate comprising: (a) a first container part for containing a volume of the concentrate; (b) a first valve part in communication with said volume; (c) a second container part having a second mating valve part therein and having means forming an outlet opening, said second container part movable to selectively move said first and second valve parts with respect to each other to allow, while said first and second valve parts are moved apart, a continuous flow of said concentrate from said first part, through said valve parts and out said outlet opening; (d) means establishing a constricted area through which concentrate must flow when being dispensed, the cross section of said constricted area being predetermined as a function of the viscosity of said concentrate; (e) means to permit introduction of a gas from outside the container to the interior of said first container part; (f) means to maintain an essentially constant head pressure in the interior of said first container part over a range of concentrate levels in said first container part, whereby said means establishing and said means to maintain, together will result in a controlled constant flow rate from said outlet opening; (g) said first container part comprises a bottle with a neck and said second container part comprises a closure part including a cap disposed over said neck; and (h) said first valve part comprising an insert in said neck, said insert having an outer part with a large bore, and an inner part with a smaller bore in communication with said bottle, and said second valve part comprising a projecting member on said cap arranged to abut against said insert, said projection having a central bore therethrough to the outside of said cap, a tube extending from said bore through said inner part of said insert, with a clearance, for connecting a source of pressure to the inside of said container.
