Abstract

A container at least to some extent composed of a sheet of composite material, where the composite material includes an aluminum foil with a first and a second surface side, a first polymer layer, bonded to at least one of the two surface sides, where the aluminum foil covers, by way of the polymer layer, at least one aperture of a holder, where the composite material and the holder together form the container, where the holder accepts at least one analytical aid in a cutout, where the aluminum foil has been molded.

Claims

1. A container, comprising:

a sheet of composite material comprising a pressed or deep-drawn aluminum foil with first and second surface sides and a first polymer layer bonded to at least one of the two surface sides; and

a holder having an aperture and a cutout that accepts an analytical aid, the composite material and the holder together forming the container;

wherein the aluminum foil with the first polymer layer bonded thereto covers the aperture.

2. The container as claimed in claim 1, wherein the polymer layer comprises a thermoplastic polymer.

3. The container as claimed in claim 2, wherein the thermoplastic polymer is a polyester.

4. The container as claimed in claim 3, wherein the polyester is selected from the group consisting of polycarbonate, polyethylene naphthalate, polybutylene terephthalate, polyethylene terephthalate, and polyester resin, and mixtures of at least two thereof.

5. The container as claimed in claim 1, wherein the thickness of the aluminum foil is from 10 to 30 μ

m.

6. The container as claimed in claim 1, wherein the composite material includes a further polymer layer.

7. The container as claimed in claim 1, wherein the analytical aid comprises a puncture element or a test field or both, for the detection of an analyte in a body fluid.

8. The container as claimed in claim 1, wherein the analytical aid comprises a hydrophilic coating.

9. The container as claimed in claim 1, wherein the first polymer layer is hydrophilic prior to use.

10. The container as claimed in claim 1, wherein the thickness of the first polymer layer is in the range from 0.5 to 10 μ

m.

11. The container as claimed in claim 1, wherein the thickness of the first polymer layer is in the range from 2 to 8 μ

m.

12. The container as claimed in claim 1, wherein the thickness of the first polymer layer is in the range from 3 to 6 μ

m.

13. The container as claimed in claim 1, wherein the container is made from an aluminum foil with at least one embossment.

14. A process for the production of a container for the storage of analytical aids, comprising:

providing a holder with a plurality of analytical aids;

protectively covering at least one portion of the holder with a sheet of composite material including an aluminum foil bonded to a polymer layer, wherein the polymer layer faces toward the holder; and

heating the polymer layer so that the polymer layer melts at least to some extent and bonds to the holder and forms a container, wherein, prior to or during the process of protectively covering at least one portion of the holder with the sheet of composite material, the aluminum foil is pressed or deep-drawn.

15. The process as claimed in claim 14, wherein the polymer layer comprises a thermoplastic polymer.

16. The process as claimed in claim 15, where the thermoplastic polymer is a polyester.

17. The process as claimed in claim 16, where the polyester is one selected from the group consisting of:

polycarbonate, polyethylene naphthalate, polybutylene terephthalate, polyethylene terephthalate, and polyester resin, and mixtures of at least two thereof.
