The present invention relates to capsules for housing pharmaceutical preparations for powder inhalers with increased medicinal product safety and capsules for pharmaceutical preparations for powder inhalers with improved adaption to use in powder inhalers. The capsules consist of non-water-soluble, hydrophobic plastics, which themselves do not substantially influence the pharmaceutical quality of the contents, but improve the usability of the filled capsules in respect of their operation, the period of use and/or the geographical location of their use and are advantageous in various steps from manufacture to use.

1. A capsule, for use as reservoir for pharmaceutical preparations in powder inhalers, comprising two capsule elements each open on one side, the elements being a capsule body and a capsule top the relative sizes of the elements allowing them to be inserted telescopically into each other via their openings so that a stable, sealed cavity of defined volume is formed, wherein: the capsule elements are of a non-water-soluble plastic material,two annular channels lying behind one another relative to the opening, running peripherally around a first capsule element are formed on the inside or outside of the first capsule element in the vicinity of its opening andtwo annular raised sections lying behind one another relative to the opening, running peripherally around the other capsule element are formed on the outside or inside of the other capsule element in the vicinity of its opening, provided that when the annular channels are formed on the inside of the first capsule element then the raised sections are formed on the outside of the other capsule element and the other capsule element fits inside the first capsule element and that when the annular channels are formed on the outside of the first capsule element then the raised sections are formed on the inside of the other capsule element and the first capsule element fits inside the other capsule element, andfurther provided that the raised section furthest from the opening is continuous around the capsule element and is higher and/or wider and/or has more surface area than the raised section closest to the opening and the raised section closest to the opening is optionally segmented,the raised sections and the annular channels being positioned correspondingly such that the two raised sections catch within the two annular channels upon the telescopic closure of the two capsule elements,the first raised section closest to the opening of the other capsule element and the first channel closest to the opening on the first capsule element, capable of forming a pre-seal of the elements when the first raised section catches within the first channel, the opening of which by pulling apart the two capsule elements requires a first force, andthe second raised section furthest from the opening of the other capsule element and the first channel on the first capsule element capable of forming a main closure when they catch within each other, the opening of which by pulling apart the two capsule elements requires a second force,and the first force to be applied for opening is smaller than the second force. 2. The capsule according to claim 1, wherein the first force is up to 3 N. 3. The capsule according to claim 1, wherein when a main closure of the elements is formed it cannot be opened by pulling apart the capsule elements without destroying them. 4. The capsule according to claim 1, wherein the annular channels are formed on the outside of the capsule body and the raised sections are formed on the inside of the capsule top. 5. The capsule according to claim 1, wherein the depth of at least one annular channel is 0.03 to 0.1 mm. 6. The capsule according to claim 5, wherein the depth of the channel is 0.05-0.08 mm. 7. The capsule according to claim 5, wherein the depth of the channel is 0.065 mm. 8. The capsule according to claim 1, wherein the first raised section closest to the opening is 0.04 to 0.08 mm high. 9. The capsule according to claim 1, wherein the second raised section furthest from the opening is 0.08 to 0.13 mm high. 10. The capsule according to claim 1, wherein the capsule top and the capsule body have walls which are 0.1 mm to 0.5 mm thick. 11. The capsule according to claim 1, wherein the capsule elements are made of polyethylene, polycarbonate, polyester, polypropylene or polyethylene terephthalate. 12. A method comprising loading the capsule according to claim 1 containing a pharmaceutical preparation into a powder inhaler such that the pharmaceutical preparation is capable of being administered by inhalation using the inhaler. 13. The capsule according to claim 1, wherein at least one raised section is 0.06 mm high. 14. The capsule according to claim 1, wherein at least one raised section is 0.10-0.11 mm high. 15. The capsule according to claim 1, wherein both the raised section furthest from the opening and the raised section closest to the opening are continuous around the capsule element.
