A package (1) is configured to store a powdery material (2) which is to be mixed with a solvent to form a medical solution, such as a dialysis solution. The package (1) comprises a filled cavity portion (6a) containing the powdery material (2), optionally separated into groups of different composition, and a tab portion (9) integrally formed with the filled cavity portion (6a) and being swept around the filled cavity portion (6a) so as to define a roll-up package. The tab portion (9) forms a protective barrier that shields the powdery material (2), e.g. by counteracting transport of moisture into and out of the package. The tab portion (9) may also stabilize the package. The roll-up package is compact, and simple to manufacture and handle.

1. A package for storing powdery material which is to be mixed with a solvent to form a medical solution, said package comprising: first and second overlapping sheets of flexible material which are joined to define a sealed cavity extending from a first cavity end to a second cavity end, the sealed cavity including a filled cavity portion located at the first cavity end, the filled cavity portion containing the powdery material, the filled cavity portion including two sub-cavities that are located side by side from the first cavity end towards the second cavity end and are separated from each other by a line in the first and second overlapping sheets, andan empty cavity portion extending from the filled cavity portion towards the second cavity end, the empty cavity portion free of powdery material; anda tab portion integrally formed with the filled cavity portion and being swept around the filled cavity portion so as to define a roll-up package. 2. The package of claim 1, wherein the roll-up package is generally cylindrical. 3. The package of claim 1, wherein the tab portion is swept in at least one full turn around the filled cavity portion. 4. The package of claim 1, wherein the tab portion includes the empty cavity portion. 5. The package of claim 1, wherein the filled cavity portion and the empty cavity portion are separated by a releasable seal that joins the first and second overlapping sheets. 6. The package of claim 1, wherein the filled cavity portion and the empty cavity portion are separated by a constriction region, in which the first and second overlapping sheets are brought into close proximity with each other without being fixedly attached to each other, by action of a force generated by the tab portion being swept around the filled cavity portion. 7. The package of claim 1, wherein the two sub-cavities contain a respective set of powdery material, and wherein the two sub-cavities are folded onto each other along the line by action of a force generated by the tab portion being swept around the filled cavity portion. 8. The package of claim 1, wherein the filled cavity portion comprises an elongated internal partition which joins the first and second overlapping sheets and is arranged to extend in a direction from the first cavity end towards the second cavity end, and wherein a respective set of powdery material is arranged in each of two pockets which are defined between the first and second overlapping sheets and are separated by the elongated internal partition. 9. The package of claim 1, wherein the filled cavity portion comprises an elongated internal partition which joins the first and second overlapping sheets and is arranged with a spacing from the first cavity end such that an open pocket is defined between the elongated internal partition and the first cavity end in the filled cavity portion, and wherein at least part of the powdery material is arranged in the open pocket. 10. The package of claim 1, wherein the sealed cavity is evacuated to a sub-atmospheric pressure. 11. The package of claim 1, further comprising a connector attached to a wall portion of the empty cavity portion for admitting a fluid and enabling mixing of the powdery material with a solvent within the sealed cavity as part of a process for preparing the medical solution. 12. The package of claim 1, wherein the filled cavity portion contains at least two separated sets of powdery material of different compositions. 13. The package of claim 12, wherein the sets of powdery material have different hygroscopic properties and are located in the filled cavity portion side by side from the first cavity end towards the second cavity end, and wherein the set of powdery material that is most hygroscopic is located at the first cavity end. 14. The package of claim 1, further comprising a suspension hole in the tab portion. 15. The package of claim 1, wherein the medical solution is one of a dialysis concentrate, a dialysis solution, an infusion solution, a nutrition solution, a replacement solution, and a plasma expander solution. 16. The package of claim 1, wherein the powdery material comprises an acid concentrate powder for preparation of an acid concentrate for use in dialysis. 17. The package of claim 1, which is configured for use in blood dialysis treatment or in peritoneal dialysis treatment. 18. The package of claim 1, wherein the tab portion is swept in at least two full turns around the filled cavity portion. 19. The package of claim 1, wherein the line is a fold line. 20. A method of manufacturing a package for storing powdery material which is to be mixed with a solvent to form a medical solution, said method comprising: providing a package blank that defines an interior space between two overlapping sheets of flexible material;disposing the powdery material at a first end of the interior space while leaving a non-filled portion that extends from the powdery material to an opposite second end of the interior space;sealing the interior space of the package blank to form a sealed cavity comprising the non-filled portion and a filled cavity portion containing the powdery material, the filled cavity portion located at the first end and including two sub-cavities located side by side from the first end towards the second end and separated by a line in the two overlapping sheets, the non-filled portion extending from the filled cavity portion towards the second end; andsweeping a portion of the package blank, including the non-filled portion of the sealed cavity, around the filled cavity portion, so as to form a roll-up package. 21. The method of claim 20, wherein the line is a fold line.
