Abstract

A container and cap assembly for storing and packaging moisture-sensitive items comprising an assembly with a container and a cap, a portion of the cap includes a lid that is attached by a hinge to the cap portion, the container has a container base, and a sidewall depending upwardly from the base, a top container surface extends inward from the sidewalls, the top container surface is provided with an opening that permits access to the interior of the container, the cap portion has a base portion with an outer periphery that extends over at least a portion of the container portion. the cap base is provided with a skirt that depends downwardly from the base portion, the skirt is configured at a location on the base portion that allows the skirt to enter into a sealing relationship with the container portion, 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 cap, and at least a portion of the interior of the container base is composed of a desiccant entrained plastic.

Claims

1. A substantially moisture tight container and cap assembly for storing and packaging moisture-sensitive items comprising an assembly with a container and a cap, the cap is attached by a hinge to the container, the container has a container base, and a sidewall depending upwardly from the container base, a top container surface extends inward from the sidewall of the container, the top container surface is provided with an opening that permits access to an interior of the container, the cap has an outer periphery that extends over at least a portion of the container, the cap is provided with a skirt that depends downwardly therefrom, the opening of the top container surface is bounded by a lip that extends upward from the top container surface, the lip of the top container surface extends around the periphery of the opening of the top container surface, the skirt of the cap is positioned at a location on the cap that allows the skirt of the cap to enter into a closing relationship with the lip of the top container surface, wherein the skirt of the cap fits over a periphery of the lip of the top container surface, the cap further includes a lip seal member that depends downwardly therefrom, the lip seal member of the cap is configured to abut at least a portion of the interior side of the lip of the top container surface when the cap is in the closed position and wherein the lip seal member provides a sealing position, in addition to the one between the skirt of the cap and the lip of the top container surface, and applies pressure on the lip of the top container surface from the inside out, which in turn applies pressure on the skirt of the cap, thereby tightening the seal between the skirt of the cap and the lip of the top container surface, resulting in a substantially moisture tight seal between the cap and the container.

2. The container and cap assembly of claim 1 wherein a portion of the cap serves as a tab for facilitating the opening and closing of the container assembly.

3. The container and cap assembly of claim 1 wherein at least a portion of the interior of the container base is composed of a desiccant entrained plastic.
