Abstract

The present invention relates to a cap for consuming a liquid from a container comprising at least one hole for the exit of liquid from the container and at least one hole for the entrance of air into the container, said air inlet incorporating a check valve allowing the entrance of air but not the exit of liquid therethrough, said valve being built into the body of the cap.

Claims

1. A cap, made from a single material, formed by a top surface, a cover adapted to fit the top surface, and a perimetric side wall configured to be fitted on an opening of a liquid container, with at least one liquid outlet for the exit of liquid from the liquid container and at least one air inlet, flush with the top surface of the cap, for the entrance of air into the container, comprising

a check valve configured to allow the entrance of air into the container, and prevent the exit of the liquid from the container;

said check valve built into the cap and protruding inwardly from an inside of the top surface of the cap;

said check valve further comprising a tubular body with two ends, such that a first end is located in the air inlet, and the second end opposite the first comprises contacting walls configured to close the tubular body when at rest or when exerting external pressure on the container and its walls are separated opening the tubular body when in use or when creating the vacuum inside the container;

the perimetric side wall containing threads configured to screw the cap to the opening of the liquid container;

wherein the cover, the check valve, the perimetric side wall, and the threads are an integral one-piece construction.

2. The cap according to claim 1, characterized in that it comprises coupling means for coupling to said container built into the cap forming a single body.

3. The cap according to claim 1, characterized in that said check valve comprises a tubular body with two ends, and wherein the tubular body extends into the container.

4. The cap according to claim 2, characterized in that said coupling means are a threading for fitting them on the container located in the perimetric wall of the cap.

5. The cap according to claim 1, characterized in that the cap and the check valve are made of a substantially identical non-resilient rigid material.

6. The cap according to claim 1, characterized in that the non-resilient rigid material is made of a plastic material such as polyethylene or polypropylene.

7. The cap according to claim 1, characterized in that the non-resilient rigid material is manufactured by means of injection in a single injection.

8. The cap according to claim 1, wherein the cover with internal projections is configured for plugging the at least one liquid outlet and the at least one air inlet.

9. The cap according to claim 1, characterized in that the at least one liquid outlet is open.

10. The cap according to claim 1, characterized in that the at least one liquid outlet comprises a guiding element, with a top end and a bottom end, with the same section as the at least one liquid outlet and coaxial or centered with respect to it.

11. The cap according to claim 10, characterized in that the guiding element is maintained coaxial or centered by the action of at least three ribs extending from the bottom part of the surface of the cap to the bottom end of the guiding element.

12. The cap according to claim 10, characterized in that it comprises a plugging element which moves along the guiding element.

13. The cap according to claim 1, wherein the check valve is configured to self-seal mechanically.

14. The cap according to claim 1, wherein the check valve comprises two flaps that are biased to seal together.

15. The cap according to claim 14, wherein each of the two flaps are elongated.

16. The cap according to claim 14, wherein the two flaps and the cap are integral and constructed from one-piece.

17. The cap according to claim 1, wherein the check valve is formed by two flaps that extend from an inside of the top surface of the cap and an opening in the top surface of the cap.

18. The cap according to claim 17, wherein the opening is a slit.

19. The cap according to claim 1, wherein the check valve is configured to unseal due to a drop in pressure on an inside of the cap.

20. The cap according to claim 1, wherein the integral one-piece construction is made from a single material.

21. The cap according to claim 20, wherein said single material is not latex or silicone.

22. A cap according to claim 1, wherein said check valve has a length between the two ends and an opening on the top surface of the cap having a width;

said length between the two ends of the check valve is greater than the width of the opening of the valve.

23. A cap according to claim 1, wherein said check valve has on opening on the top surface of the cap;

said opening have a width and a length, and wherein the length of said opening is greater than the width of the opening.
