## Abstract

A hinged container is disclosed, including a base, a lid, and a hinge joining the base and lid, allowing the lid to pivot open or closed relative to the base. One of the base and the lid has a circular, outwardly tapered outer seal member disposed at least partially within its outer perimeter. The other of the base and the lid has a circular, inwardly-tapered inner seal member disposed at least partially within its outer perimeter. The inner and outer seal members are positioned to engage concentrically to wedge the inwardly and outwardly tapered surfaces together and form a seal when the base and the lid are closed, and to disengage concentrically to part the inwardly and outwardly tapered surfaces when the base and the lid are opened.

## Claims

### Claim 1

A hinged container comprising:
(a) a base having an outer perimeter;
(b) a lid having an outer perimeter;
(c) a hinge joining the base and lid, allowing the lid to pivot open or closed relative to the base;
(d) a circular, outwardly tapered outer seal member defining a center axis and mounted in fixed relation to one of the base and the lid and disposed at least partially within the corresponding outer perimeter;
(e) a circular, inwardly-tapered inner seal member defining a center axis and mounted in fixed relation to the other of the base and the lid and disposed at least partially within the corresponding outer perimeter;
(f) the inner and outer seal members being positioned to engage concentrically to wedge the inwardly and outwardly tapered surfaces together and form a seal when the base and the lid are closed, and to disengage concentrically to part the inwardly and outwardly tapered surfaces when the base and the lid are opened;
wherein the base is provided with a latch portion, the lid is provided with a catch, and the latch portion is positioned to engage the catch when the lid and the base are closed; the hinged container further comprising at least one push tab in association with the latch portion, whereby when the push tab is depressed, the latch portion is released from the catch.

### Claim 2 (depends on 1)

The hinged container of claim 1, in which the inner and outer seal members are configured to provide a moisture-tight seal.

### Claim 3 (depends on 1)

The hinged container of claim 1, in which the inner and outer seal members are configured to be resealable.

### Claim 4 (depends on 1)

The hinged container of claim 1, in which the base and lid perimeters are substantially congruent.

### Claim 5 (depends on 1)

The hinged container of claim 1, in which the base and lid perimeters are substantially registered when the base and lid are closed.

### Claim 6 (depends on 1)

The hinged container of claim 1, which is generally clam shell shaped.

### Claim 7 (depends on 1)

The hinged container of claim 1, in which the hinge is integral with the base and lid.

### Claim 8 (depends on 1)

The hinged container of claim 1, in which the base and/or the lid has a non-round outer perimeter.

### Claim 9 (depends on 1)

The hinged container of claim 1, further comprising a spring in association with the push tab wherein the spring returns the push tab from its depressed position.

### Claim 10 (depends on 1)

The hinged container of claim 1, in which the latch portion has an abutment that engages an abutment on the catch when the lid and the base are closed.

### Claim 11 (depends on 1)

The hinged container of claim 1, in which a film guide is mounted in the base.

### Claim 12 (depends on 11)

The hinged container of claim 11, in which the film guide comprises a desiccant entrained polymer.

### Claim 13 (depends on 1)

The hinged container of claim 1, in which at least one of (a) the lid and the seal member mounted in the lid, (b) the base and the seal member mounted in the base, (c) the lid and the hinge, and (d) the base and the hinge, are made of the same material.

### Claim 14 (depends on 13)

The hinged container of claim 13, in which the base is made of 2 materials and one of the materials is a desiccant entrained polymer.

### Claim 15 (depends on 13)

The hinged container of claim 13, in which at least one of the lid, the seal member mounted in the lid, the base, the seal member mounted in the base, and the hinge is made of polypropylene.
