In the primed position, the plunger 30 may be provided outside the cartridge 16, oriented to enter the cartridge 16 and urge a single test strip through the dispensing outlet 20. The plunger 30 has a length sufficient to urge a portion of a single test strip 24 partially through the dispensing outlet 20 when the container 5 is changed from a primed to an unprimed position. The test strip 24 may be urged through dispensing outlet 20 a distance that allows a user to sufficiently grip and remove the test strip 24 from the container 5. The test strip 24 may protrude from the dispensing outlet 20 for a length ranging from about 3 mm to about 30 mm, or from about 5 mm to about 25 mm. It is also contemplated that the test strip may protrude from the dispensing outlet 20 other distances suitable to allow a user to grasp and remove a test strip 24 from the container 5.

As the container shifts from primed position to the unprimed position, the test strip 24 may be ejected from the cartridge 16 by the plunger 30. The test strip 24 may push through the strip exit 48, and displace the strip exit seal 28, and exit through the dispensing outlet 20. The strip exit seal 28 may contact the test strip 24 as it leaves the cartridge 16 to minimize any air and moisture ingress.

Once a test strip is removed from the container, the strip exit seal 28 reseals to reestablish the hermetic seal within the cartridge 16. In the unprimed position, the plunger 30 remains disposed partially within the cartridge 16, with the plunger entrance seal 26 pressing against it, operable to hermetically seal the container.

Referring to FIG. 2, in one embodiment, the container 5 comprises a housing inlet seal 64 and a plug seal 66 provided on the plunger 30. The housing inlet seal 64 may interact with the housing inlet 34 when the container 5 is in the primed position to seal the container 5 from air and moisture ingress. The housing inlet seal 64 may comprise a tapered o-ring type seal provided over the plunger 30. However, the housing inlet seal 64 may also comprise other sealing devices operable to provide a hermetic seal in the housing inlet 18 when the container is an unprimed position.

The plug seal 66 may be provided on the part of plunger 30 that extends furthest away from the housing inlet 34 when the container is in an unprimed position. The plug seal 66 may comprise a tapered plug that sealably interacts with the housing inlet 35 when the container 5 is in an unprimed position. The plug seal 66 may comprise a flexible material suitable to provide a seal when the container is in an unprimed position.

Referring to FIG. 4, in accordance with another embodiment, the container 5 may comprise a housing 10 that defines a cavity 12, a lid 14, and a slidable seal 52. The housing 10 comprises a cartridge 16, a plunger 30, a dispensing outlet 20 and a biasing member 22. In this embodiment, the cartridge has only two locations of potential air and moisture ingress, the junction between the lid 14 and the housing track 38, and the dispensing outlet 20. The slidable seal 52 may be provided on the inside diameter of the lid 14, and sealably interacts with the housing track 38 to form a hermetic seal within the volume(s) contained by the housing 10 and the portion of the lid beyond the slidable seal 52.

The slidable seal 52 may be located on the inside diameter of the lid 14, only marginally above the open face of the lid 14. The lid comprises a seal gap 54 sized to accommodate a range of slidable seals 52. The seal gap 54 may be sized to accommodate a range of seal sizes, suitable to provide a hermetic seal. The slidable seal 52 should be selected to allow the lid 14 to slide along the housing track 38, and change the container from a primed position to an unprimed position.

Referring to FIG. 4, as the lid 14 slides along the housing track 38 towards the housing shoulder 36 from a primed position to an unprimed position, the plunger 30 may contact a single test strip 24 and urge it partially through the dispensing outlet 20. As the container is transitioned from the unprimed position to the primed position, the plunger 30 moves upward towards the plunger entrance 50 until the distal end of the plunger 30 engages the test strip 24. As the container 5 is transitioned from the primed position to the unprimed position, the test strip is pushed through the strip exit 48. The test strip may protrude from the dispensing outlet 20 a distance that allows a user to sufficiently grip and remove the test strip 24 from the container 5. The test strip 24 may protrude from the dispensing outlet 20 for a length ranging from about 3 mm to about 30 mm, or from about 5 mm to about 25 mm. It is also contemplated that the test strip may protrude from the dispensing outlet 20 other lengths suitable to allow a user to grasp and remove a test strip from the container.

Referring to FIG. 4, the slidable seal 52 may be provided in a seal gap 54 within the lid 14. Alternatively, the slideable seal may be provided on the outside diameter of the housing track in a seal gap similarly provided. In addition, other slidable seal configurations are also contemplated. The slidable seal 52 may comprise a range of different materials. The slidable seal 52 may comprise a rubber, synthetic rubber, elastomeric materials, and other materials, synthetic and natural operable to form a hermetic seal. The slidable seal 52 may comprise an o-ring type seal.

The slidable seal 52 may provide friction between the housing 10 and the lid 12. The friction may be enough to prevent the lid from sliding along the housing without actuation of the container 5 by a user. In addition, the cartridge 16 may comprise at least two positional notches that define an unprimed position and a primed position. The at least two positional notches may interact with a positional knob provided on the housing to retain the container in a primed and unprimed position until the container is actuated by a user. The positional knob may interact with the positional notches where the positional knob may slide out of the positional notch when a certain force threshold is met.

Referring again to FIG. 4, in accordance with one embodiment, the container 5 may comprise a dispensing outlet seal member 78. The dispensing outlet seal member 78 may cooperate with the dispensing outlet 20 to form a hermetic seal within the container 5. The dispensing outlet seal member 78 may comprise a duckbill seal, that allows a single test strip to pass through the seal. The dispensing outlet seal member 78 may reseal after each test strip 24 is dispensed, in order to maintain the hermetic seal within the container 5. The dispensing outlet seal member 78 may also take other configurations operable to reseal after the test strip is dispensed. The dispensing outlet seal member 78 may also be manufactured from a range of materials known to those skilled in the art including, but not limited to, rubber, plastic, and other synthetic and natural materials suitable to provide a passable outlet forming a substantially moisture-proof and air tight barrier over the dispensing outlet 20.

Referring further to FIG. 4, the container 5 may comprise a spring 55 provided in the cavity 12. The spring 55 may be located in the side of the cavity adjacent the cavity dispensing wall 34. The spring 55 may be statically mounted in the cavity 12. In one configuration, the spring 55 may be provided in the bottom of the cavity 12, integrated with the frame 40. The spring 55 may cooperate with the plunger 30 to longitudinally urge the plunger 30 towards the dispensing outlet 20.

In one embodiment, the spring 55 may comprise a torsion spring having a plunger leg 56 and a biasing leg 58. The biasing leg 58 may extend along the cavity dispensing wall 34, and urge the biasing member 22 towards the chamber biasing wall 46. Simultaneously, the plunger leg 56 may urge the plunger 30 upwards towards the dispensing outlet 20. The spring 55 may comprise any material suitable to provide adequate tension to the container in order to simultaneously urge the biasing member 22 towards the chamber dispensing wall 44, and urge the plunger 30 towards the dispensing outlet 20. In one embodiment, the biasing actuator may be replaced by the biasing leg 58 of the spring 55. The biasing leg 58 may contact the biasing platform 76 and urge the biasing platform towards the cavity biasing wall 32.

Referring to FIG. 5, in accordance with another embodiment, the container 5 may comprise a housing 10 defining a cavity 12, and a sliding member 60 mounted on the housing 10 to provide for relative motion defining a primed and an unprimed position. In this embodiment, it is contemplated that no lid is included, and the housing 10 is completely encased and hermetically sealed, other than the housing inlet 18 and the dispensing outlet 20.

The sliding member 60 may interact with the plunger 30, such that when the sliding member 60 is moved from a primed position to an unprimed position, the plunger 30 may move longitudinally within the cavity 12 about the same distance as the sliding member 60. The sliding member 60 may connect to the plunger 30 via a plunger mount 62. The plunger mount 62 may connect the sliding member 60 to the plunger 30 in a manner sufficient to urge the plunger 30 towards the dispensing outlet 20 when the sliding member 60 moves from a primed position to an unprimed position. In one configuration, the plunger leg 56 of the spring 55 may be connected to the plunger to ensure that the plunger 30 stays in the unprimed position once a test strip 24 is dispensed.

The plunger 30 may urge a single test strip 24 partially through the dispensing outlet 20 when the sliding member changes from a primed position to an unprimed position. The test strip may protrude from the dispensing outlet a distance that allows a user to sufficiently grip and remove the test strip 24 from the container 5. The test strip 24 may protrude from the dispensing outlet 20 for a length ranging from about 3 mm to about 30 mm, or from about 5 mm to about 25 mm. It is also contemplated that the test strip may protrude from the dispensing outlet 20 other lengths suitable to allow a user to grasp and remove a test strip from the container.

The plunger mount 62 may cooperate with the housing inlet 30 in a manner sufficient to provide a hermetic seal when the container 5 is in an unprimed position. The plunger mount 62 may be complementarily shaped to sit within the housing inlet 30. The plunger mount 62 may include a housing inlet seal 64, that sealably interacts with the housing inlet 18 to provide a hermetic seal. The housing inlet seal 64 may be integrally mounted in conjunction with the plunger mount 62. In one embodiment, the plunger mount 62 may be integrated with the plunger 30, so they are provided as a unitary component. Alternatively, the housing inlet seal 64 may be radially disposed on the plunger mount 62.

The sliding member may comprise a range of materials. The sliding member 60 may be sized sufficient to allow the sliding member 60 to slide over the housing track 38 in a longitudinal fashion. In one configuration, the sliding member 60 has a length that is substantially the same as the length of the housing 10. In another potential configuration, the sliding member 60 may have a length slightly less than the length of the housing 10. In one configuration, the housing track 38 may have a stop that prevents the sliding member 60 from moving past a certain stopping position relative to the housing 10.

Referring to FIGS. 6A and 6B, in another embodiment, the sliding member 60 may be pivotally mounted to rotate along the outside of the housing 10, in a manner sufficient to change the container from a primed position to an unprimed position. The arrow in FIG. 6A shows the rotation the sliding member 60 from a primed position to an unprimed position. As the container transitions from a primed position to an unprimed position, the plunger is urged upwards into the storage chamber, sufficient to urge a single test strip 24 through the dispensing outlet 20. The plunger 30 may be a flat flexible wire made of steel or plastic (not shown). As the sliding member 60 is rotated from a primed position to an unprimed position, the plunger engages the end of the test strip, and urges it through a strip exit

As the sliding member 60 is transitioned from a primed to an unprimed position, the sliding member 60 creates translational motion that is transferred through a series of gears to move the plunger 30 from a primed position to an unprimed position (not shown).
