Abstract

Storage container for test strips with a holder in which the test strips are contained and which is closed by a lid. The lid has an elastic seal on its inner side which, when the storage container is closed presses against a rim of the holder preventing an invasion of moisture into the storage container. Holder and lid are connected to one another by a hinge. When the storage container is closed, the seal is deformed and pushes the lid after release of a locking means such that the storage container is at least partially opened.

Claims

1. A storage container for test strips, said storage container comprising:

a holder having a cavity therein, with a first side of said cavity forming an orifice defined by a rim;

a lid hingably connected to said holder, said lid including an elastic seal on an inner side thereof, said elastic seal having a shape which corresponds to said rim of said orifice, said elastic seal engaging said rim when said lid is in a closed position closing said orifice; and

engagement means on said lid and on said holder for engaging said lid and said holder, thereby holding said lid in the closed position;

wherein said elastic seal is configured to deform against said rim when said lid is moved to the closed position and the engagement means is engaged, and wherein the elastic seal is configured to return to a nondeformed state when the engagement means is released, and wherein the elastic seal returning to the non-deformed state provides a force which moves the lid to a partially open position upon a release of said engagement means.

2. A storage container as recited in claim 1, wherein said engagement means comprises a first engagement element on said holder and a second, corresponding engagement element on said lid.

3. A storage container as recited in claim 1, wherein said hinge is configured to move said lid to the partially open position when the engagement means is released.

4. A storage container as recited in claim 1, wherein the lid comprises a plastic of a first elasticity, and the elastic seal is fabricated from a plastic of a second elasticity, said plastic of said second elasticity being more elastic than the plastic of the first elasticity, said elastic seal being applied to the lid by an injection molding process.

5. A storage container as recited in claim 1, wherein the deformation of said elastic seal is a compression deformation.

6. A storage container as recited in claim 1, wherein said lid comprises an outer annular ridge on an outer periphery thereof, and an inner annular ridge on the inner side of said lid, with a gap between said inner and outer annular ridges, and wherein the elastic seal is located in the gap.

7. A storage container as recited in claim 1, said lid comprising an inner annular ridge on the inner side thereof, wherein said elastic seal surrounds said annular ridge.

8. A storage container as recited in claim 1, wherein said elastic seal has an L-shaped cross section, and is disposed on the inner side of the lid.

9. A storage container as recited in claim 1, wherein said lid comprises one of polypropylene and polyamide, and wherein said elastic seal comprises one of styrene elastomer and polyolefin elastomer.

10. A storage container as recited in claim 1, wherein said holder has a cross-section of an oval shape.

11. A storage container as recited in claim 1, wherein said lid is hingably connected to said holder by a film hinge.

12. A storage container as recited in claim 1, wherein said lid is hingably connected to said holder by a film hinge, and wherein said holder, said hinge, and said lid are formed of a single injection molded component.

13. A storage container as recited in claim 1, wherein said engagement means comprises a recess on a lateral surface of the lid and a projection on an outer surface of the holder, wherein upon an engagement of the lid with the holder, the projection engages the recess to hold the storage container in a closed position.

14. A storage container as recited in claim 1, wherein said engagement means comprises a projection on an inner lateral surface of the lid and a corresponding recess an outer surface of the holder.

15. A storage container as recited in claim 1, wherein said lid includes a tongue portion thereupon, said engagement means engaging said tongue portion.

16. A storage container as recited in claim 1, wherein said lid is hingably connected to said holder whereby said lid can be rotated by up to 190°

from the closed condition with respect to the holder.

17. A storage container as recited in claim 16, wherein said lid includes a tongue portion which is configured such that when said lid is at a fully open condition, said tongue intersects a longitudinal axis of said cavity, thereby forming a baffle to restrict contents of the cavity from being removed from the cavity.

18. A storage container as recited in claim 1, wherein said holder includes an outer chamber thereupon, said outer chamber being accessible to receive identification data therein, said outer chamber being configured to enable access to said identification data.

19. A storage container as recited in claim 1, further comprising desiccant means disposed in said cavity.

20. A storage container as recited in claim 1, further comprising desiccant means disposed on the inner side of said lid.

21. A storage container as recited in claim 1, wherein said lid is hingably connected to said holder by a hinge, said hinge providing an opening force sufficient to open said lid by 20°

to 60°

after release of said engagement means.

22. A storage container as recited in claim 1, wherein said engagement means includes a slide being slidably attached to said holder, said slide having an edge which engages the lid upon slidably movement thereof in a predetermined direction, thereby releasing the engagement means.

23. A storage container as recited in claim 22, wherein said edge is tapered.

24. A storage container as recited in claim 1, wherein said elastic seal comprises an annular ridge disposed on the inner side of the lid, said annular ridge engaging the rim when the lid is closed, thereby sealing the cavity.

25. A storage container as recited in claim 1, wherein a second side of the cavity is closed by a bottom surface of the holder.

26. A storage container as recited in claim 25, further comprising a desiccant means disposed in said cavity adjacent said bottom surface of said holder.

27. A storage container as recited in claim 1, wherein said engagement means comprises locking means for lockingly engaging said lid and said holder.

28. A storage container as recited in claim 8, wherein a surface of said elastic seal which forms said L-shaped cross section engages said rim when said lid is in the closed position.

29. A method for accessing test elements in a storage container, said method comprising the steps of:

providing a storage container including a holder having a cavity therein, with a first side of said cavity forming an orifice defined by a rim, with a lid hingably connected to the holder and including an elastic seal on an inner side thereof, with the elastic seal having a shape which corresponds to the rim of the orifice, with the elastic seal engaging the rim when the lid is in a closed position, and an engagement means for engaging the lid and the holder, thereby holding the lid in the closed position, wherein the elastic seal is configured to deform against the rim when the lid is moved to the closed position, and the engagement means is engaged, and wherein the seal is configured to a return to a non-deformed state when the engagement means is released, and wherein the elastic seal returning to the non-deformed state provides a force to move the lid to a partially open position upon a release of said engagement means;

providing said storage container with test strips and in a closed condition with said engagement means engaged;

said method further comprising the steps of

opening said engagement means, thereby releasing the lid to enable the elastic seal to move the lid to a partially opened position;

tilting the storage container such that said test strips slide through the orifice through the force of gravity, and wherein said test strips contact said lid in said partially open position.

30. A method for accessing test elements as recited in claim 29, wherein said step of providing the storage container includes providing a bottom surface on a second side of said cavity.
