ABSTRACT:
There is provided an overcap for a resealable container that includes a drying agent layer. The drying agent layer is included in a top portion of the overcap and is positioned below a top layer of the top portion such that the drying agent layer is exposed to the interior of the container. The overcap may be formed from a multilayered coextruded sheet having a top layer of polymer material and a drying agent layer mixed with a polymer material. The multilayered coextruded sheet may also include a barrier layer, a polymer layer, and/or additional drying agent layers. Alternatively, the drying agent layer may be joined to the overcap by an injection molding process or by an adhesive. The drying agent layer is exposed to moisture in the interior of the container such that the drying agent layer is operable to absorb moisture from the air that enters the interior of the container during the opening and resealing of the container.
