A seal system usable to seal containers and other fluid components to allow fluid flow through the seal system in a first direction yet prevent fluid flow through the seal system in an opposite direction. The seal system is particularly useful for facilitating insertion of a tube, such as a straw, into a container to withdraw fluids yet prevent fluids from leaking from a container once the straw has been withdrawn. The seal system may be formed from a flange having an opening and attached to the opening of the container, and a tubular body extending from the flange into the container. The tubular body may be formed from a transition section attached to the flange and extending generally away from the flange, and a collapsed seal section attached to the transition section and extending from the transition section away from the flange.

I claim: 1. A one way seal, comprising: a flange having an opening and adapted to be attached to an opening of a fluid component; a tubular body extending from the flange, wherein the tubular body is comprised of a transition section attached to the flange and extending generally away from the flange and a collapsed seal section attached to the transition section and extending from the transition section away from the flange; the collapsed seal section is configured such that an inner surface of a first side of the collapsed seal section is in contact with an inner surface of a second side of the collapsed seal section that is opposite to the first side in a relaxed condition; wherein the first and second sides are attached to each other at first and second axially extending side edges that are generally opposite to each other and wherein the first and second axially extending side edges are positioned between first and second sides; and wherein the tubular body is formed from a flexible, sheet material and is adapted to extend and be positioned within the fluid component. 2. The one way seal of claim 1, wherein the first and second side edges are formed from welds. 3. The one way seal of claim 1, wherein the collapsed seal section is formed from plastic. 4. The one way seal of claim 3, wherein the plastic has a thickness of between about 0.005 inches and about 0.035 inches. 5. The one way seal of claim 1, further comprising a removable lid attached to the flange and configured to seal the opening in the flange by extending across the opening in the flange. 6. The one way seal of claim 5, wherein the removable lid is formed from a flexible material. 7. The one way seal of claim 5, further comprising a removable cap with a movable plug, wherein the plug is movably secured to the cap with a movable arm such that the plug may be removed from the opening in the cap to permit fluids to pass therethrough yet remain attached to the cap with the movable arm. 8. The one way seal of claim 1, wherein the collapsed seal section is generally straight. 9. The one way scat of claim 1, wherein the collapsed seal section is generally curved along a length of the collapsed seal section. 10. The one way seal of claim 1, wherein the collapsed seal section is generally curved along a longitudinal axis of the collapsed seal section. 11. The one way seal of claim 1, wherein the tubular body may further comprise commercial advertising. 12. The one way seal of claim 1, further comprising a tube inserted through the opening in the flange, through the transition section, and through the collapsed seal section. 13. The container with a one way seal of claim 12, wherein the first and second edges are formed from welds. 14. The container with a one way seal of claim 12, further comprising a removable lid attached to the flange and configured to seal the opening in the flange by extending across the opening in the flange. 15. The container with a one way seal of claim 14, wherein the removable lid is formed from a flexible material. 16. The container with a one way seal of claim 14, further comprising a removable cap with a movable plug, wherein the plug is movably secured to the cap with a movable arm such that the plug may be removed from the opening in the cap to permit fluids to pass therethrough yet remain attached to the cap with the movable arm. 17. The one way seal of claim 1, wherein the first side is shorter than the second side. 18. A container with a one way seal, comprising: the container having an opening; a flange attached to the opening of the container, wherein the flange includes an opening; a tubular body extending from the flange into the container, wherein the tubular body is comprised of a transition section attached to the flange and extending generally away from the flange and a collapsed seal section attached to the transition section and extending from the transition section away from the flange; the collapsed seal section is configured such that an inner surface of a first side of the collapsed seal section is in contact with an inner surface of a second side of the collapsed seal section that is opposite to the first side in a relaxed condition; wherein the first and second sides are attached to each other at first and second axially extending side edges that are generally opposite to each other and wherein the first and second axially extending side edges are positioned between first and second sides; and wherein the tubular body is formed from a flexible, sheet material. 19. The container with a one way seal of claim 18, wherein the collapsed seal section is formed from plastic. 20. The container with a one way seal of claim 19, wherein the plastic has a thickness of between about 0.005 inches and about 0.035 inches. 21. The container with a one way seal of claim 18, wherein the collapsed seal section is generally straight. 22. The one way seal of claim 18, wherein the collapsed seal section is generally curved. 23. The one way seal of claim 18, wherein the tubular body may further comprise commercial advertising. 24. The one way seal of claim 18, further comprising a tube inserted through the opening in the flange, through the transition section, and through the collapsed seal section. 25. The one way seal of claim 18, wherein the first side is shorter than the second side. 26. The one way seal of claim 18, wherein the second side has rounded corners.
