PROBLEM TO BE SOLVED: To provide a container cover capable of functioning to absorb moisture from the air entering the interior of the container and capable of re-sealing the container while the container is opened and closed again. SOLUTION: The desiccating agent layer 36 is contained in the top of the cover 12 and is disposed lower in an upper layer in the top, and the desiccating agent layer is designed to be exposed inside the container. The cover can be formed of a multilayered coextruded sheet having the desiccating agent layer where the upper layer 34 of a polymer material and the polymer material are mixed. The coextruded sheet may also include a barrier layer, a polymer layer, and/or an additional desiccating agent layer. COPYRIGHT: (C)2005,JPO&NCIPI
