ABSTRACT:
A transparent enclosure having an internal cavity divided into two portions, the first of which is designed to accept and hermetically seal a container. The second is designed to accept and hold a mixture of a desiccant and a humidity sensitive color indicator. The first and second portions of the cavity are separated by a barrier wall which contains a filter in the central area of the wall. The filter comprises a porous area in the barrier wall and is formed of a wicking polymer that conducts the humidity within the container to the desiccant and humidity sensitive color indicator, drying the contents of the container and causing the color indicator to provide a visual indication of the humidity within the container. The peripheral surface of the barrier wall is designed to engage and seal the barrier wall within the cavity in order to physically isolate the contents of the container from the desiccant, while providing a means by which the moisture within the container may be extracted by the desiccant.
