What I claim is: 1. Container comprising at least one vacuum chamber with an access opening, the access opening being closed off by a closing mechanism after a vacuum is produced, an enclosure downstream from the access opening and in which a valve element is disposed, said valve element being open
What I claim is: 1. Container comprising at least one vacuum chamber with an access opening, the access opening being closed off by a closing mechanism after a vacuum is produced, an enclosure downstream from the access opening and in which a valve element is disposed, said valve element being opened during the generation of the vacuum and closed after the vacuum is generated, said enclosure being filled with a medium containing an element or compound capable of diffusing, which diffuses if the enclosure and, with that, the vacuum chamber are not closed off tightly, through the access opening. 2. The container of claim 1, wherein the medium is a liquid. 3. The container of claim 1, wherein the medium is water. 4. The container of claim 1, wherein the medium is enriched with helium as the element, capable of diffusing. 5. The container of claim 1, wherein the enclosure is tubular and fastened at one end in the region of the access opening and, at the other end of which, the valve element is provided. 6. Container according to claim 1, wherein said container is a beverage container with a self-cooling device. 7. Container according to claim 1, wherein said container is a beer barrel. 8. The container of claim 1, wherein the enclosure is fastened at a threaded sleeve, which defines the access opening and in which the thread of a closing-off screw is screwed. 9. The container of claim 8, comprising a covering cap, which covers the closing-off screw and is welded at the edge. 10. The container of claim 1, wherein said enclosure is a first tubular enclosure, and further comprising a second tubular enclosure, surrounding the first tubular enclosure, and communicating in a region below the valve element with the first said enclosure and having at an upper side, at least one air inlet opening. 11. The container of claim 10, wherein the second enclosure is disposed at the upper side jointly at a threaded sleeve and, at the lower side, at a common holding part, having an enclosure connection and comprising a sealing seat for the valve element. 12. The container of claim 1, wherein the valve element is a ball valve with a ball, which may be moved with respect to a sealing seat. 13. The container of claim 12, wherein the ball is constructed from an undeformable material and the sealing seat from a deformable material. 14. The container of claim 12, wherein the sealing seat and the ball are constructed from a deformable material. 15. The container of claim 12, wherein the enclosure, in the region of the access opening, is constructed in such a manner that the ball, movable in the chamber during the generation of the vacuum, does not seal the access opening. 16. The container of claim 12, wherein the enclosure is a tubular enclosure which is bent in the vicinity of the access opening. 17. The container of claim 12, wherein the ball is constructed from a deformable material and the sealing seat is constructed from an undeformable material. 18. The container of claim 17, wherein the deformable material comprises silicone and the undeformable material comprises a metal. 19. The container of claim 1, wherein the valve is a needle valve with a needle, which may be moved with respect to a sealing seat. 20. The container of claim 19, wherein the sealing seat has a central aperture with a sealing ring, which interacts with a needle sealing seat of the needle for the purpose of sealing and through which the needle passes, a holding part with an aperture with an internal thread, into which the needle can be screwed with an external thread provided in the region of the lower end of the needle being positioned below the sealing seat. 21. The container of claim 20, wherein a device for engaging a tool for screwing the needle is provided at the upper end of the needle. 22. The container of claim 20, wherein the length of the internal thread and the external thread at the holding part and the length of the needle sealing seat are such, that the needle can be screwed through the external thread and that the seal is retained after the needle is screwed through. 23. The container of claim 20, wherein the sealing ring is constructed from a deformable material. 24. The container of claim 23, wherein the sealing seat is constructed from a deformable material.
