Abstract

A resealable container including a housing, a lid coupled to the housing, and a basket received within the housing and including side walls defining an interior space, and a retainer extending over at least a portion of the interior space and configured to support at least one test element in at least one of a side-to-side direction and a front-to-back direction within the basket.

First claim

What is claimed is:

1. A resealable container comprising:
a housing;
a lid coupled to the housing; and
a basket received within the housing and including
a first side wall, a second side wall, and a floor defining an interior space, and
a retainer extending over at least a portion of the interior space and configured to support at least one test element in a side-to-side direction and a front-to-back direction within the basket, the retainer further comprising:
a first plurality of fingers extending from the first side wall to a parting line positioned between the first side wall and the second side wall in the interior space; and
a second plurality of fingers extending from the second side wall to the parting line, wherein:

a first finger in the first plurality of fingers and a second finger in the second plurality of fingers are configured to deform in response to insertion of at least one test element into the interior space to provide side-to-side support of the at least one test element, the first finger and the second finger are configured to be deflectable in a range of motion from a non-deflected position extending to the parting line and a deflected position extending into the interior space and exerting a force on sides of the at least one test element, wherein in the non-deflected position the first finger extends parallel to the floor; and
an unused third finger in the first plurality of fingers and an unused fourth finger in the second plurality of fingers are configured to not deform in response to the insertion of the at least one test element into the interior space to provide front-to-back support to the at least one test element,
wherein the interior space has a trapezoidal cross-section in which the first side wall and the second side wall form two non-parallel sides of the trapezoidal cross-section and the floor forms a third side of the trapezoidal cross-section, such that the at least one test element is maintained in an upright position.

2. The resealable container of claim 1 , wherein the retainer is formed as a single piece and the first plurality of fingers and the second plurality of fingers are cut from the single piece.

3. The resealable container of claim 1 , wherein the first finger and the second finger are each formed as a bristle configured to deform and provide side-to-side support for one test element.

4. The resealable container of claim 1 , wherein the first finger and the second finger are each formed as a wiper configured to deform and provide side-to-side support for a plurality of test elements.

5. The resealable Container of claim 4 , wherein the wiper is configured to provide air flow to the plurality of test elements.

6. The resealable container of claim 1 , wherein the first plurality of fingers and the second plurality of fingers are formed in an annular member of the retainer.

7. The resealable container of claim 1 , wherein the retainer defines a substantially inverted U-shaped cross-sectional profile.

8. The resealable container of claim 1 , wherein the retainer includes an end spring configured to provide front-to-back support to the at least one test element.

9. The resealable container of claim 8 , wherein the end spring is a living spring.

10. The resealable container of claim 8 , wherein the retainer is formed from a single piece and the end spring is cut from the single piece.

11. The resealable container of claim 1 , wherein the retainer is adhered to the basket.

12. The resealable container of claim 1 , wherein the retainer is press fit into the basket.

13. The resealable container of claim 1 , wherein the retainer is constructed of at least one of flexible plastic, flexible bristles, flexible rubber, and thin metal.

14. The resealable container of claim 1 , wherein in the non-deflected position a distal end of the at least one segment is a first distance from the sidewall, and in the second position the distal end of the at least one segment is a second distance from the sidewall that is no greater than half of the first distance.

15. A basket for use in a resealable container, the basket comprising:
a sidewall and a floor defining an interior space; and
a retainer including a plurality of segments, each segment in the plurality of segments being deflectable between a first deflected position and a second non-deflected position,
when in the first position at least one segment in the plurality of segments is configured to extend into the interior space and provide side-to-side support of a test element that deflects the at least one segment into the first position by exerting a force on a side of the test element, and
when in the second position at least one other segment in the plurality of segments that does not deflect is configured to provide front-to-back support of the test element, wherein in the second non-deflected position the at least one segment extends parallel to the floor,
wherein the interior space has a trapezoidal cross-section in which the first side wall and the second side wall form two non-parallel sides of the trapezoidal cross-section and the floor forms a third side of the trapezoidal cross-section, such that the at least one test element is maintained in an upright position.

16. The basket of claim 15 , wherein the test element is a test strip.

17. The basket of claim 15 , wherein the plurality of segments are perforated.

18. The basket of claim 15 , wherein a first segment and a second segment of the plurality of segments overlap.

19. The basket of claim 15 , wherein in the first deflected position a distal end of the at least one segment is a first distance from the sidewall, and in the second non-deflected position the distal end of the at least one segment is a second distance from the sidewall that is at least twice as large as the first distance.
