Abstract

The invention is within the field of packaging and storing of test elements that are usually sensitive towards atmospheric humidity or water vapor. The invention concerns a system for the storage of test elements for the analysis of sample liquids in which two or more test elements are present in a storage container which can be sealed water-vapor tight and contains a desiccant inside.

Claims

1. A system for the storage of a plurality of test elements within the system, the test elements being for the analysis of sample liquids, the system comprising

a holder having an opening;

a storage container having an opening, for containing the plurality of test elements, and received at least partially within the holder;

a flap located on one end of the holder, and a reset device;

wherein the flap is pressed by the reset device onto the holder opening or the storage container opening to protect test elements inside of the system against water vapor.

19. A system as claimed in claims 1 or 2, wherein said reset device comprises at least one spring.

2. A system for the storage of a plurality of test elements within the system, the test elements being for the analysis of sample liquids, the system comprising

a base structure having an opening, and containing the plurality of test elements therein such that the test elements can be removed from the base structure through the opening,

a flap located on one end of the base structure and releasably closing the opening, and

a reset device which moves the flap to open and close the opening and which presses the flap onto the opening to seal the test elements inside of the system against ambient water vapor.

3. System of claim 2, wherein the base structure is a unitary or one-piece unit.

4. System of claim 2, wherein the reset device is located within the base structure.

5. System of claim 2, wherein the base structure comprises a holder having an opening;

a storage container having an opening, containing the plurality of test elements, and received at least partially within the holder; and

the flap seals one of the openings.

6. System of claim 5, wherein the storage container is removable from the holder.

7. System of claim 6, wherein the storage container can be inserted into the holder from a side opposite the flap.

8. System of claim 2, wherein a desiccant is present inside the base structure.

9. System of claim 2, wherein the base structure has a slide which is operably connected to the flap to open the flap.

10. System of claim 2, wherein a sealing element is located between the flap and the storage container.

11. System of claim 2, wherein batch-specific data of the test elements are located on the system alphanumerically, as bar codes or as magnetic strips.

12. System of claim 2, wherein the system when full contains 10 to 40 test elements.

13. System of claim 2, wherein the reset device automatically closes the opening by pressing on the flap.

14. System of claim 2, wherein the reset device has only one point of rest, and that point of rest is achieved when the flap closes the opening.

15. System of claim 14, wherein the reset device can be digitally engaged by a user to open the flap from the opening, and, upon digital disengagement, the flap automatically returns to a sealing position to seal the opening.

16. A system as claimed in claim 2, wherein said base structure contains test elements which are inserted in a position facing the opening of the system, from which they can be removed when the flap is opened.

17. A system as claimed in claim 2, wherein when said system is closed, said flap is pulled or pressed onto the opening of said base structure by said reset device, and the reset device is under tension at all times.

18. A system as claimed in claim 17, wherein the direction of the press of said reset device is substantially perpendicular to the rim of the opening of said base structure when said system is closed.

20. A system for the storage of a plurality of test elements within the system, the test elements being for the analysis of sample liquids, the system comprising

storage means having an opening said storage means for containing a plurality of test elements;

holder means for holding the storage means, the holder means having an opening;

flap means located on one end of the holder means, the flap means for sealing one of the openings against passage of water vapor; and

reset means for pressing the flap onto said one of the openings to seal same.

21. System of claim 20, wherein the reset means is for digital engagement by a user to move the flap from sealing contact with the opening to permit withdrawal of a test element, and for causing the flap to return to sealing contact with the opening upon digital disengagement.

22. A method for the storage and individual removal of a plurality of test elements for the analysis of sample liquids within a system in which the system is sealed against ambient water vapor, said method comprising moving a flap sealing an opening of a base structure away from the opening, removing at least one test element from a storage compartment located within said base structure, and urging said flap against the opening of said base structure by automatically engaging a reset device which has only one point of rest in the system, that point of rest being achieved when said flap closes said opening to cause said flap to automatically return to a sealing position to seal the opening.

23. A method as claimed in claim 22, the method further comprising operating an opening device which moves said flap away from the opening of said base structure.

24. A method as claimed in claim 23, the method further comprising moving a point of connection between said reset device and said base structure.

25. A method as claimed in claim 22, the method further comprising initially forcing said flap perpendicularly away from the opening of said base structure by said reset device when said system is opened.

26. A method as claimed in claim 25, the method further comprising forcing said flap towards the side of said base structure device upon further opening so that the test elements can be withdrawn from the opening of said base structure.

27. Method of claim 22, wherein the flap is moved away from the opening by digital engagement of the reset device by a user, and the flap automatically is returned to the sealing position upon digital disengagement.
