Abstract
A canister for containing a particulate-type product such as a ready-to-eat cereal. The canister includes a side wall, a bottom closure and a plastic lid. The side wall defines at least a portion of a tubular body having an upper opening, a lower opening and an internal storage region for containing the particulate-type product. In this regard, the side wall includes a first, paper-based layer and a second, plastic-based layer. The first, paper-based layer has an inner surface and an outer surface. The second, plastic-based layer is bonded to the inner surface of the first, paper-based layer. The bottom closure is connected to the side wall so as to encompass the bottom opening. The plastic lid is openably secure to the tubular body at the upper opening. In this regard, the plastic lid provides selective access to the internal storage region. With this configuration, the plastic lid facilitates rapid fabrication of the canister, as well as providing for increased canister durability.
