ABSTRACT:
Moisture impervious packaging systems for retaining articles include a container body and a closure lid hingedly connected thereto. The container body includes a bottom wall and upwardly extending peripheral walls ending in an upper surface that defines an access opening into an interior compartment in which the articles are retained. The lid includes a peripheral frame member providing the side margins of the lid, and a separate moisture impervious sheet adhered to the frame member for providing the top wall of the lid. The moisture impervious sheet constituting the top wall of the lid preferably is also adhered to the upper surface of the container body for providing a primary moisture impervious seal for the interior compartment of the container body.
The moisture impervious packaging systems are formed by maintaining the peripheral frame member about the outer periphery of the container body with an upper surface of the frame member spaced outwardly from, and adjacent to the upper surface of the container body to circumscribe the access opening into the interior compartment, and, after articles have been deposited into the interior compartment, adhering the moisture impervious sheet to the upper surface of the peripheral frame member to complete the formation of the lid, and preferably to the upper surface of the container body to provide the primary moisture impervious seal for the interior compartment.
