Abstract

The present disclosure relates to a closure which uses a bubble valve with three chambers. A transverse bubble element on the product side of the bubble valve can expand or inflate thereby inhibiting flow, or contract or deflate thereby allowing flow. A longitudinal bubble element to the side of the bubble valve is used to receive the contents from the transverse bubble element when the transverse bubble element is deflated.

Claims (35)

1. A valve including:

a base;

a fluid communication channel formed adjacent to the base;

a protruding valve element on the base, extending into the fluid communication channel;

a first bubble element on the base, positioned on a product side of the protruding valve element and extending into the fluid communication channel, wherein inflation of the first bubble element blocks flow in the fluid communication channel to the protruding valve element; and

a second bubble element on the base, positioned laterally from the protruding valve element, wherein inflation of the second bubble element allows flow in the fluid communication channel to the protruding valve element.

2. The valve of claim 1 wherein the protruding valve element is a third bubble element.

3. The valve of claim 2 wherein the third bubble element is filled with a first air, gas or fluid.

4. The valve of claim 3 wherein the first and second bubble elements are filled with a second air, gas or fluid.

5. The valve of claim 4 further including a bubble communication channel between the first bubble element and the second bubble element.

6. The valve of claim 5 wherein the first bubble element and the second bubble element include a total quantity of the first air, gas or fluid to inflate one and only one of the first bubble element and the second bubble element.

7. The valve of claim 6 wherein the first bubble element is positioned transversely along the fluid communication channel.

8. The valve of claim 7 wherein the second bubble element is positioned longitudinally along the fluid communication channel.

9. The valve of claim 8 wherein the third bubble element is teardrop-shaped with a pointed end directed to the product side and an arcuate end point to a consumer side.

10. The valve of claim 9 further including a channel layer, wherein the fluid communication channel is formed, at least in part, between the third bubble element and the channel layer.

11. A valve including:

a base;

a fluid communication channel formed adjacent to the base;

a protruding valve element on the base, extending into the fluid communication channel;

a first bubble element on the base, positioned on a product side of the protruding valve element and extending into the fluid communication channel, wherein inflation of the first bubble element blocks flow in the fluid communication channel to the protruding valve element, and deflation of the first bubble element allows flow in the fluid communication channel to the protruding valve element; and

a second bubble element positioned on an opposite side of the base from the first bubble element, wherein inflation of the second bubble element allows deflation of the first bubble element.

12. The valve of claim 11 wherein the protruding valve element is a third bubble element.

13. The valve of claim 12 wherein the third bubble element is filled with a first air, gas or fluid.

14. The valve of claim 13 wherein the first and second bubble elements are filled with a second air, gas or fluid.

15. The valve of claim 14 further including a bubble communication channel between the first bubble element and the second bubble element.

16. The valve of claim 15 wherein the first bubble element and the second bubble element include a total quantity of the first air, gas or fluid to inflate one and only one of the first bubble element and the second bubble element.

17. The valve of claim 16 wherein the first bubble element is positioned transversely along the fluid communication channel.

18. The valve of claim 17 wherein the third bubble element is teardrop-shaped with a pointed end directed to the product side and an arcuate end point to a consumer side.

19. The valve of claim 18 further including a channel layer, wherein the fluid communication channel is formed, at least in part, between the third bubble element and the channel layer.

20. A valve including:

a base;

a fluid communication channel formed adjacent to the base;

a protruding valve element on the base, extending into the fluid communication channel;

a first bubble element on the base, positioned on a product side of the protruding valve element and extending into the fluid communication channel, wherein inflation of the first bubble element blocks flow in the fluid communication channel to the protruding valve element, and deflation of the first bubble element allows flow in the fluid communication channel to the protruding valve element; and

a second bubble element separated from the first bubble element, wherein inflation of the second bubble element allows deflation of the first bubble element.
