Abstract

A substantially moisture tight container and lid assembly for storing and packaging moisture-sensitive items comprising an assembly with a container and a lid, the lid is attached by a hinge to an upper housing portion of the container, the lid includes a lip seal member that depends downwardly from the lid, the lip seal member is configured to abut at least a portion of the interior side of the container when the lid is in the closed position resulting in a substantially moisture tight seal between the lid and the lid, and the container assembly further comprising a base portion and an upper housing portion, the upper housing portion is capable of being snap-fit into the base portion by employing a lip seal mechanism to form a substantially moisture-tight seal.

First claim

What is claimed is:

1. A method of making a resealable container and lid assembly for storing and packaging moisture-sensitive items, the method comprising:
a) injection molding a container and a lid, the container having a container base and a sidewall extending upwardly from the container base;
i) a top of the container having an opening that permits access to an interior of the container;
ii) the opening being spaced away from an outer surface of the sidewall of the container by at least a portion of the thickness of the sidewall of the container;
iii) the lid being attached by a hinge to the container, the lid being movable about the hinge from an opened position to a closed position, the lid having an outer periphery that extends over at least a portion of the container, the lid having a skirt that extends downwardly therefrom, the lid having an underside;
iv) the skirt of the lid being positioned at a location on the lid that allows the skirt of the lid to close over the top of the container, wherein the skirt of the lid fits over a periphery the top of the container;
wherein the skirt of the lid includes an inwardly facing rounded extension, a lip of the top of the container includes an outwardly facing rounded extension, the inwardly facing rounded extension of the skirt of the lid and the outwardly facing rounded extension of the lip abut and interlock with each other when the lid is in the closed position and wherein a space is provided between the lip and the underside of the lid when the lid is in the closed position;

v) the lid further including a flexible lip seal member that extends downwardly therefrom to a position below where the extensions abut and interlock when the lid is in the closed position, the flexible lip seal member of the lid being configured to abut at least a portion of an interior of the sidewall of the container when the lid is in the closed position;
wherein the flexible lip seal member is configured to deflect to provide a sealing position, when the skirt of the lid is closed over the top container; and

b) injection molding a desiccant entrained polymer sleeve or liner; and
c) inserting the desiccant entrained polymer sleeve or liner into the container body.

2. The method of claim 1 , wherein the moisture-sensitive items are diagnostic test strips.

3. The method of claim 2 , further comprising:
d) inserting the diagnostic test strips into the container body.

4. The method of claim 1 , wherein step c) further comprising press-fitting the desiccant entrained polymer insert or liner into the container.

5. The method of claim 1 , wherein the outwardly facing rounded extension projects around the periphery of the lip.

6. The method of claim 1 , wherein a moisture ingress of the container, after three days, is less than about 1500 micrograms of water.

7. The method of claim 1 , wherein a moisture ingress of the container, after three days, is less than about 500 micrograms of water.

8. The method of claim 1 , wherein a moisture ingress of the container, after three days, is less than about 300 micrograms of water.
