Abstract

The present invention provides a container for test strips for the analysis of body fluids, comprising a container body (2) with a circular removal opening (2a), a sealing surface (14) facing the axis (A) of the opening and a stopper (3) for the closure of the removal opening (2a) which has a cover plate (4), a hollow plug (7) attached thereto with an outwardly facing sealing beading (8), a drying agent cell (6) within the hollow plug and a support element (10) by means of which the plug is supported radially inwardly, wherein the support element is so constructed that it abuts the hollow plug in a region axially displaced away from the cover plate (4) with regard to the zenithal line (15) of the sealing beading (8), whereas axially, at the height of the sealing beading (8), between the inner side of the hollow plug and the drying agent cell, even when the stopper (3) is in a position permitting removal, an annular gap (9 ) is present so that the hollow plug (7) is radially inwardly elastically deformable in the region of the sealing beading (8).

Claims

1. A container for test strips comprising:

a container body having a first end, a second end and an axis, said first end defining a circular opening and having a sealing surface facing the axis of the container;

stopper means for removably closing said circular opening, said stopper means having a cover plate,

a hollow plug attached to the cover plate and extending into the container, said hollow plug having an inner and an outer side;

a sealing beading attached to the hollow plug and facing outwardly in a direction away from the axis, the sealing beading having a zenithal line corresponding to a maximum extension line which extends horizontally through the sealing beading relative to the axis, a drying agent cell located within the hollow plug; and

support element means for supporting the hollow plug in the container, which support element means abuts against the inner side of the hollow plug in a region which is axially displaced away from the zenithal line toward the interior of the container;

the inner side of the hollow plug and an outer side of the drying agent cell defining an annular gap in the axial height of the sealing beading whereby the hollow plug is elastically deformable in an area of the sealing beading in a radial inward direction relative to the axis, said annular gap being maintained when the stopper means is in its container closing position.

2. The container according to claim 1, wherein the support means comprises a water vapour-permeable disc simultaneously covering the drying agent cell.

3. The container according to claim 2 wherein the hollow plug further comprises a flanged end facing away from the cover plate for reception of said disc.

4. The container according to claim 1, wherein the support element is axially displaced relative to the zenithal line of the sealing beading by at least 2 mm.

5. The container according to claim 4, wherein the support element is axially displaced relative to the zenithal line by at least 3 mm.

6. The container according to claim 1, wherein the circular opening narrows on at least a part of its circumference with regard to a diameter of the sealing surface in a direction away from the second end of the container.

7. The container according to claim 6, wherein the first end of the container comprises a continuous annular beading to thereby narrow the circumference part of the circular opening.

8. The container according to claim 6, wherein the first end of the container comprises a plurality of holding knops to thereby narrow the circumference part of the circular opening.
