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

selectively opening and closing a lid for substantially hermetically sealing a container;

radially arranging a plurality of test strips in the container; and

rotating a cover to selectively expose a single one of the plurality of test strips;

wherein the step of rotating the cover comprises aligning an opening in the cover with a region of the container for containing one of the plurality of test strips; and

wherein the step of rotating the cover further comprises depressing a button disposed on the cover; and

wherein the step of exposing a single one of the test strips further comprises engaging a first set of cam surfaces provided on the cover with a second set of cam surfaces provided on the container to rotate the cover upon depression of a button.

2. The method according to claim 1, further comprising the step of inverting the container to dispense the exposed test strip through the cover.

3. The method according to claim 1, wherein the step of rotating the cover further comprises overcoming a biasing element biasing the cover to maintain alignment between an opening in the cover and a first region of the container for containing one of the plurality of test strips, such that the opening aligns with a second region of the container for containing another one of the plurality of test strips.

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

providing a container for radially arranging a plurality of test strips therein;

exposing a single one of the plurality of test strips by rotating a cover disposed on the container and having an opening therein; and

operating a lid for selectively opening the container and closing and substantially hermetically sealing the container; and

wherein the step of exposing a single one of the test strips comprises depressing a button disposed on the cover; and

wherein the step of exposing a single one of the test strips further comprises engaging a first set of cam surfaces provided on the cover with a second set of cam surfaces provided on the container to rotate the cover upon depression of a button.

5. The method according to claim 4, further comprising the step of inverting the container to dispense the exposed test strip through the cover opening.

6. The method according to claim 4, further comprising the step of providing a biasing element biasing the cover to maintain alignment between the opening and a first region of the container for containing one of the plurality of test strips, such that the biasing element is overcome to align the opening with a second region of the container for containing another one of the plurality of test strips.

7. The method according to claim 4, wherein the step of providing the second set of cam surfaces comprises:

providing a cam sleeve on which the second set of cam surfaces are disposed; and

fixedly engaging the cam sleeve with the container.
