7. The slipcover according to claim 5 , wherein the two fold-down lateral parts are of identical length and of such a size that the volume of the parallelepiped base corresponds to the volume of the first envelope once the air is extracted.

8. The storage slipcover according to claim 1 , wherein the at least one opening of the second envelope is two openings, the openings being located at opposite ends of the second envelope.

9. A bag for storage and/or transport of articles, comprising a suitcase, wherein the bag is equipped with a storage slipcover for receiving articles, the storage slip cover comprising a first envelope extending vertically and fitted at its upper end with an opening for insertion of said articles, and a plate fitted with folding means for the formation of a parallelepiped base in which is placed at least the lower part of the first envelope, said storage slipcover further comprising a second envelope fixed horizontally at the lower end of the first envelope so that the first and second envelopes form a single element, the second envelope comprising dimensions slightly greater than the plate and at least one opening for introducing this plate horizontally into said second envelope, said slipcover being suitable to be enclosed in said suitcase.

10. The bag according to claim 9 , wherein the suitcase comprises a peripheral vertical wall, and wherein this wall comprises on its internal face reception means for receiving the parallelepiped base for the purpose of stabilising the slipcover in the suitcase.

11. A bag for storage and/or transport of articles, comprising a suitcase, wherein the bag is equipped with a storage slipcover for at least one article, such as a textile article, comprising a first envelope extending vertically and fitted at its upper end with an opening for insertion of said at least one article, and a plate fitted with folding means for the formation of a parallelepiped base in which is placed at least the lower part of the first envelope, said storage slipcover further comprising a second envelope assembled horizontally below the lower end of the first envelope, this second envelope comprising dimensions slightly greater than the plate and at least one opening for introducing this plate into said second envelope, said slipcover being suitable to be enclosed in said suitcase, and

wherein said suitcase comprises a peripheral vertical wall, and this wall comprises on its internal face reception means for receiving the parallelepiped base for the purpose of stabilising the slipcover in the suitcase, and

wherein the peripheral vertical wall comprises at least two lateral sides, said bag comprising a storage slipcover according to claim 5 , wherein the reception means are constituted by rebates located at the level of the upper angular ends of said at least two lateral sides, said rebates enabling reception of the angular ends of the lateral parts, which can be folded down, of the plate during formation of the parallelepiped base.

12. A kit comprising a bag for storage and/or transport of articles, comprising a suitcase, wherein the bag is equipped with a storage slipcover for at least one article, such as a textile article, comprising a first envelope extending vertically and fitted at its upper end with an opening for insertion of said at least one article, and a plate fitted with folding means for the formation of a parallelepiped base in which is placed at least the lower part of the first envelope, said storage slipcover further comprising a second envelope assembled horizontally below the lower end of the first envelope, this second envelope comprising dimensions slightly greater than the plate and at least one opening for introducing this plate into said second envelope, said slipcover being suitable to be enclosed in said suitcase,

wherein the first envelope comprises on one of its walls air extraction means, of valve type, for extracting air contained inside said first envelope, and

wherein said kit also comprises a pumping apparatus for extraction of air in said slipcover.

13. The kit according to claim 12 , wherein the lower part of the first envelope, the second envelope and the plate are plane rectangular in shape, the width of the plate being less than the width of the lower part of the first envelope and that of the second envelope, the length of the plate being also less than the length of the lower part of the first envelope and of that of the second envelope.

14. The kit according to claim 13 , wherein the folding means comprises two folding lines extending transversally and separating said plate into a central part and two fold-down lateral parts for the formation of the parallelepiped base.

15. The kit according to claim 13 , wherein the second envelope comprises two lateral ends each fitted with an opening for insertion of the plate.

16. The kit according to claim 14 , wherein the two fold-down lateral parts are of identical length and of such a size that the volume of the parallelepiped base corresponds to the volume of the first envelope once the air is extracted.
