Abstract

A container for moisture sensitive test elements comprising a container body (2, 102, 202), an insert (22, 122, 220) fitting in container body, whereby a cavity (18, 118) is created between outer surface of insert wall (24, 124, 240) and inner surface of container body wall (4, 104, 204), and a lid (50, 150, 250) dimensioned to seal container open end when in a closed position, wherein a desiccant material is contained within the cavity (18, 118) between container body wall and insert wall. Insert wall defines a hollow channel (29, 129, 229) which is dimensioned that at least one test element ex-tents from the insert channel facilitating accessibility to an individual test element for the testing of an analyte of interest. Desiccant material includes an indicator whose colour changes when exposed to moisture indicating to a user whether contents therein, i.e. test elements, have been compromised by environmental factors.

Claims

1. A container for moisture sensitive test elements comprising a container body (2, 102, 202) comprising a closed bottom (6, 106) and an open end, an insert (22, 122, 220) fitting in container body (2, 102, 202), whereby a cavity (18, 118) is formed between outer surface (24a, 124a) of insert wall (24, 124, 240) and inner surface (4b, 104b) of container body wall (4, 104, 204), and a lid (50, 150, 250) dimensioned to seal container open end when in a closed position, wherein a desiccant material is contained within cavity (18, 118) between inner surface of container body wall and outer surface of insert wall.

2. A container according to claim 1, wherein the lid (50, 250) is integrally connected to the insert (22, 220).

3. A container according to claim 1, wherein the lid (150) is integrally connected to a retaining element (131), which fits in the open end of container body (2).

4. A container according to claim 1, wherein the walls (24, 124, 240) of insert (22, 122, 220) form a rectangular longitudinal hollow channel (29, 129, 229) dimensioned to contain a stack of test elements.

5. A container according to claim 4, wherein length of hollow channel (29, 129, 229) is dimensioned to be less than length of test element so that at least one test element contained therein extends above insert wall (24, 124, 240) into lid hollow portion (61, 161) when lid is in a closed sealing position.

6. A container according to claim 1, wherein a cavity (18) for containment of the desiccant material is formed between the bottom wall (6) of container body (2, 202) and the bottom (20) of insert (22, 220).

7. A container according to claim 6, wherein the bottom (20) of insert (22, 220) is of a porous material and/or moisture permeable material.

8. A container according to claim 1, wherein a circumferential annular space (118) is formed between outer surface of insert wall (124a) and inner surface of container wall (104b) for containment of the desiccant material.

9. A container according to claim 8, wherein the walls (24) of insert (22) are of a porous material and/or moisture permeable material.

10. A container according to claim 1, wherein the desiccant material contains an indicator whose colour changes when exposed to moisture.

11. A container according to claim 1, wherein the container body (2, 102202) has a transparent wall and/or wall section.

12. A container according to claim 1, wherein the insert (22, 122, 220) is opaque.

13. A method of manufacturing a container according to claim 1 comprising the steps of:

(i) moulding a container body (2, 202) with integral walls (4, 204) and bottom (6);

(ii) co-moulding insert (22, 220) and lid (50, 250);

(iii) inserting desiccant material in a cavity (18, 118) between inner surface of container body wall and outer surface of insert wall; and

(iv) assembling container body (2, 202) and insert (22, 220); and

/or

(i) co-moulding container body (102) and insert (122);

(ii) co-moulding retaining element (131) and lid (150);

(iii) inserting desiccant material in a cavity (18, 118) between inner surface of container body wall and outer surface of insert wall; and

(iv) assembling container body (102) including insert (122) and retaining element (131) with co-moulded lid (150).
