Abstract

A container (100) for isolating first and second fluids, such as beverage concentrate components, until dispensing is provided, as well as methods of assembly and dispensing. The container can have first (111) and second (113) enclosed bodies for containing the first and second fluids to be dispensed and an insert (130) directing fluid from the enclosed bodies towards one or more valves or separate discharge paths (148a, 148b).

Claims

1. A container for isolating a first liquid and a second liquid prior to dispensing, the container comprising:

a first, squeezable enclosed body for containing the first liquid and having a first body access opening;

a second, squeezable enclosed body for containing the second liquid and having a second body access opening, the second body access opening being adjacent to the first body access opening;

a common cap secured to at least one of the first and second bodies, the common cap having a dispensing aperture;

an insert positioned between the access openings of the first and second bodies and the common cap, the insert defining a dispensing path having an upstream entrance in fluid communication with the first and second body access openings and a downstream exit in fluid communication with the dispensing aperture; and

a valve moveable, in response to the first and second enclosed bodies being squeezed, from a closed position blocking flow from both the dispensing path and through the dispensing aperture and isolating the first and second liquids upstream of the valve to an open position permitting flow through both the dispensing path and the dispensing aperture to dispense the first and second liquids from the container;

wherein the valve is a flexible diaphragm moveable, in response to the first and second enclosed bodies being squeezed, from the closed position to the open position;

wherein the flexible diaphragm includes a plate portion including one or more slits that form one or more flaps in the flexible diaphragm; and

wherein a mixing chamber is disposed upstream of the valve when the valve is in the open position.

2. The container of claim 1, wherein the mixing chamber is disposed downstream of the downstream exit of the insert when the valve is in the open position.

3. The container of claim 1, further comprising a gasket positioned between the access openings of the first and second bodies and the insert.

4. The container of claim 1, wherein the insert includes a valve seat configured to permit the valve to sit thereon.

5. The container of claim 1, wherein the first enclosed body and the second enclosed body are positioned side-by-side in the container.

6. The container of claim 1, wherein the first enclosed body and the second enclosed body share a common wall configured to separate the first enclosed body from the second enclosed body.

7. The container of claim 6, wherein the first and second liquids flowing out from the downstream exit of the dispensing path flow in a direction generally parallel to the common wall.

8. The container of claim 6, wherein the valve has a central axis generally parallel to the common wall.

9. The container of claim 1, wherein the first enclosed body and the second enclosed body are a unitary, blow-molded or injection molded structure.

10. A method of dispensing a first liquid and a second liquid from the container of claim 1, the method comprising:

decreasing an interior volume of the first enclosed body to cause at least some of the first liquid to exit the first enclosed body and be discharged through the dispensing aperture; and

substantially simultaneously decreasing an interior volume of the second enclosed body to cause at least some of the second liquid to exit the second enclosed body and be discharged through the dispensing aperture.
