Abstract

A storage container for analytical test elements includes a guide mechanism thereupon. The storage container holds a plurality of test elements attached to a tape, with each of the test elements including a test zone thereupon. The storage container is configured to expel individual test elements by passing the tape over the guide mechanism, thereby changing a direction of movement of the tape by the guide mechanism. This action detaches a test element from the tape.

Claims

1. A storage container for analytical test elements, said storage container comprising:

a guide mechanism and a housing for holding a plurality of test elements attached to a tape, with each of the test elements comprising a test zone,

wherein said storage container is configured to expel individual test elements of the plurality of test elements by passing said tape over said guide mechanism thereby changing a direction of movement of the tape by the guide mechanism and detaching a test element from said tape.

2. The storage container as recited in claim 1, wherein each of said test zones is individually sealed by said tape.

3. The storage container as recited in claim 1, wherein each test element includes a transparent pin having a front side on which is a test zone.

4. The storage container as recited in claim 1, wherein the plurality of test elements are linked together by said tape, and the storage container includes transport means for transporting the tape through the storage container by winding the tape onto a spool core and for detaching a test element emerging from the storage container from the tape by passing the tape over the guide mechanism.

5. The storage container as recited in claim 1, wherein said guide mechanism comprises a roller.

6. A storage container as recited in claim 1, wherein said guide mechanism comprises an edge.

7. A storage container as recited in claim 1, wherein said storage container including an interior spiral which stabilizes a spiral arrangement of the plurality of test elements,

wherein the individual test elements are for the analysis of sample liquids.

8. A storage container as recited in claim 1, wherein each test zone is configured to have a sample liquid applied thereto, each test element also including a sheath, with the tape being fixed onto each sheath so that each test zone is protected against entry of atmospheric humidity.
