Multi-chamber pouch and valves
The present disclosure relates to pouches or packages with at least two separate storage volumes, wherein a bubble valve, protruding element valve or pressure actuated valve is provided for each storage volume. The two bubble valves may be presented in parallel configuration, angled slightly toward each other, or at right angles to each other. The bubble valves may also have different sized openings in order to adjust the proportion of products mixed and to adjust for differing viscosities.
1. A container comprising:
a first web panel;
a second web panel sealed to the first web panel, thereby forming an interior volume in communication with a fluid dispensing channel;
a divider within the interior volume thereby defining a first storage volume and a second storage volume;
a first protruding element valve in the fluid dispensing channel thereby controlling flow from the first storage volume through the fluid dispensing channel;
a second protruding element valve in the fluid dispensing channel thereby controlling flow from the second storage volume through the fluid dispensing channel; and
wherein the first and second protruding element valves are respective first and second bubble valves, including a fluid passageway formed between a bubble layer and a channel layer.
2. The container of claim 1 wherein the bubble layer of the first and second bubble valves is attached to the second web panel, thereby forming respective first and second bubbles.
3. The container of claim 2 wherein the first web panel forms the channel layer of the first and second bubble valves.
4. The container of claim 3 wherein the first and second bubbles are filled with gas or fluid.
5. The container of claim 3 wherein there is a physical characteristic difference between the first protruding element and the second protruding element, and wherein more contents from the first storage volume are dispensed than contents from the second storage volume.
6. The container of claim 3 wherein the first and second bubble valves are arranged adjacent to each other.
7. The container of claim 6 wherein the first and second bubble valves dispense product from respective first and second storage volumes parallel to each other.
8. The container of claim 6 wherein first and second bubble valves are inclined toward each other to at least partially mix the products dispensed from respective first and second storage volumes.
9. The container of claim 1 wherein the divider is a central seal between the first and second web panels.
10. The container of claim 1 wherein the divider is a third web panel.
11. A container comprising:
a first web panel;
a second web panel sealed to the first web panel, thereby forming an interior volume in communication with a fluid dispensing channel;
a central seal within the interior volume thereby defining a first storage volume and a second storage volume;
a protruding element valve in the fluid dispensing channel thereby controlling flow from the first and second storage volumes through the fluid dispensing channel; and
wherein the protruding element valve is a bubble valve, including first and second fluid passageways formed between a bubble layer and a channel layer, the first fluid passageway being in fluid communication with the first storage volume and the second fluid passageway being in fluid communication with the second storage volume, wherein the first and second fluid passageways are divided from each other by a longitudinal seal between the bubble layer and the channel layer.
12. The container of claim 11 wherein the bubble layer of the bubble valve is attached to the second web panel, thereby forming a bubble.
13. The container of claim 12 wherein the first web panel forms the channel layer of the bubble valve.
14. The container of claim 13 wherein the bubble is filled with gas or fluid.
15. The container of claim 11 wherein the first fluid passageway has a larger cross-sectional area than the second fluid passageway, and wherein more contents from the first storage volume are dispensed than contents from the second storage volume.
16. A protruding element valve for dispensing contents of a package, comprising:
a base layer, a bubble layer, and a channel layer;
a bubble formed between the base layer and the bubble layer by a bubble seal;
a first channel seal, a second channel seal, and a longitudinal seal between the first channel seal and the second channel seal; and
a fluid dispensing channel formed between the bubble layer and the channel layer, including a first fluid passageway and a second fluid passageway,
wherein the first and second fluid passageways formed in the fluid dispensing channel between the longitudinal seal formed and the first and second channel seals respectively.
17. The protruding element valve of claim 16 , wherein the first fluid passageway has a larger cross-sectional area than the second fluid passageway.
18. The protruding element of valve of claim 16 , wherein the first fluid passageway dispenses contents from a first storage volume of the package and the second fluid passageway dispenses contents from a second storage volume of the package.
