Abstract

An apparatus for storing and dispensing a test strip includes a container configured to store a radial array of test strips. The container maintains appropriate environmental conditions, such as humidity, for storing the test strips. The container has a plurality of radially extending slots formed by a plurality of dividing walls, and each slot is sized to receive a single test strip. A rotatably positionable cover is carried by the container for covering the plurality of radially extending slots. The cover includes an opening, which, when the cover rotates, aligns with one of the slots at a time to allow removal of a single test strip located within the respective slot. Accordingly, the unused test strips remain free of contaminants such as naturally occurring skin oils on a user'"'"'s hand.

Claims

1. An apparatus for dispensing test strips, comprising:

a container including an outer wall;

a plurality of radially extending slots formed by a plurality of dividing walls, each slot sized to receive a single test strip; and

a rotatably positionable cover carried by the container for covering the plurality of radially extending slots, the cover including an opening;

wherein when the cover rotates, the cover opening aligns with one of the slots at a time to allow removal of a single test strip located within a respective slot.

2. The apparatus of claim 1, further comprising a boss centrally disposed within the container, the boss including a recess.

3. The apparatus of claim 2, wherein the cover comprises an upper surface and a lower surface, and the lower surface of the cover comprises an elongated shaft positioned within the recess of the boss.

4. The apparatus claim 3, wherein the upper surface of the cover comprises a handle.

5. The apparatus of claim 3, wherein the lower surface of the cover further comprises a plurality of detents that engage the plurality of dividing walls to control rotation of the cover.

6. The apparatus of claim 1, wherein the plurality of dividing walls extend radially inwardly from the outer wall of the container toward the center of the container.

7. The apparatus of claim 1, further comprising a sleeve forming the plurality of dividing walls.

8. The apparatus of claim 1, wherein the cover comprises a spinner that includes a first set of cam surfaces.

9. The apparatus of claim 8, further comprising a cam sleeve with a second set of cam surfaces operatively engagable with the first set of cam surfaces to rotate the spinner.

10. The apparatus of claim 9, wherein the spinner comprises at least one flexing beam.

11. The apparatus of claim 10, wherein the cam sleeve has teeth which engage the at least one flexing beam to control rotation of the spinner.

12. The apparatus of claim 8, further comprising a spring which biases the spinner.

13. The apparatus of claim 8, wherein the spinner includes a portion composed of an optically clear material.

14. The apparatus of claim 8, wherein the spinner has an elongated shaft including a stop.

15. The apparatus of claim 14, further comprising:

a boss centrally disposed within the container, the boss including a recess for receiving the elongated shaft of the spinner, the stop on the spinner contacting the boss to control movement of the spinner.

16. An apparatus for dispensing test strips, comprising:

a vial with a plurality of radially extending slots, each slot adapted to store a test strip; and

means for selectively exposing one of the plurality of radially extending slots to dispense a test strip stored in the exposed slot and for covering the remaining slots.

17. The apparatus of claim 16, wherein the means for selectively exposing one of the plurality of radially extending slots comprises a cover with a slot which exposes one of the plurality of radially extending slots.

18. The apparatus of claim 17, further comprising means for actuating the means for exposing one of the plurality of radially extending slots.

19. The apparatus of claim 18, wherein the means for actuating the means for exposing one of the plurality of radially extending slots comprises a handle attached to the cover.

20. The apparatus of claim 16, wherein the means for selectively exposing one of the plurality of radially extending slots comprises a spinner with a slot which exposes one of the plurality of radially extending slots, the spinner having a pushbutton.

21. The apparatus of claim 20, further comprising means for actuating the means for selectively exposing one of the plurality of radially extending slots.

22. The apparatus of claim 21, wherein the means for actuating the means for selectively exposing one of the plurality of radially extending slots comprises:

a plurality of first cam surfaces formed on the spinner; and

a cam sleeve comprising a plurality of second cam surfaces, the second cam surfaces interacting with the first cam surfaces so that when the pushbutton is pressed, the first cam surface engage the second cam surfaces to cause the spinner to rotate.

23. The apparatus of claim 22, wherein:

the cam sleeve further comprises a plurality of teeth; and

the spinner further comprises at least one flexing beam, the flexing beam interacting with the plurality of teeth to control movement of the spinner.

24. The apparatus of claim 22, wherein:

the container further comprises a boss with a recess; and

the spinner further comprises a shaft with a stop located in the recess, the stop controlling the movement of the spinner.

25. A method for storing and dispensing test strips, comprising the steps of:

storing a plurality of test strips in a radially arranged manner in a container having a replaceable lid; and

selectively uncovering at least one test strip in such a manner as to allow only one test strip at a time to be dispensed from the container.

26. The method for storing and dispensing test strips according to claim 25, further comprising the step of inverting the container to dispense a test strip.

27. The method for storing and dispensing test strips according to claim 25, further comprising the step of exposing one of the plurality of radially arranged test strips to allow the exposed test strip to be dispensed from the container.

28. The method for storing and dispensing test strips according to claim 27, wherein the step of exposing one of the plurality of radially arranged test strips comprises rotating a cover member.

29. The method for storing and dispensing test strips according to claim 28, wherein the step of rotating the cover member comprises the step of manipulating a handle disposed on the cover member.

30. The method for storing and dispensing test strips according to claim 28, wherein the step of rotating the cover member comprises the step of pressing a button disposed on the cover member.
