## 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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 1)

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.

### Claim 10 (depends on 1)

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

### Claim 11 (depends on 1)

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

### Claim 12 (depends on 1)

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.

### Claim 13 (depends on 1)

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.

### Claim 14 (depends on 1)

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.

### Claim 15 (depends on 1)

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

### Claim 16 (depends on 1)

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.degree. from the closed condition with respect to the holder.

### Claim 17 (depends on 16)

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.

### Claim 18 (depends on 1)

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.

### Claim 19 (depends on 1)

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

### Claim 20 (depends on 1)

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

### Claim 21 (depends on 1)

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.degree. to 60.degree. after release of said engagement means.

### Claim 22 (depends on 1)

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.

### Claim 23 (depends on 22)

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

### Claim 24 (depends on 1)

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.

### Claim 25 (depends on 1)

### Claim 28 (depends on 8)

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.

### Claim 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.

### Claim 30 (depends on 29)

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.
