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.

Canister

A canister for storing a particulate-type product. The canister comprises opposing face panels, opposing side panels, a bottom closure, a top closure and a seal membrane. The opposing side panels together with the opposing face panels define an upper opening and a lower opening. The bottom closure is connected to the opposing face panels so as to encompass the lower opening. The opposing face panels, the opposing side panels and the bottom closure combine to define an internal storage region. The top closure is connected to the opposing face panels so as to encompass the upper opening. The top closure is configured to provide selective access to the internal storage region. Finally, the seal membrane is connected to the inner surfaces of the opposing face and side panels adjacent to and extending beneath the top closure. The seal membrane forms a substantially air-tight seal at the upper opening to maintain integrity of particulate-type product disposed within the internal storage region. In addition, the seal membrane is configured to provide selective access to the internal storage region and thereby the particulate-type product. In one preferred embodiment, the canister is configured to store a food product, for example a ready-to-eat cereal.

Perforated air-tight seal membrane for a canister containing a particulate-type product

A canister for containing a particulate-type product. The canister includes opposing face panels, opposing side panels, a top closure and a bottom closure. The opposing side panels are connected to the opposing face panels to define an upper opening and a lower opening. Further, at least one of the opposing side panels or the opposing face panels includes a first paper-based layer, a second paper-based layer and an adhesive. Each of the first and second layers has an inner surface and an outer surface. The adhesive bonds the inner surface of the first layer to the outer surface of the second layer. The top closure is connected to the opposing face panels and the opposing side panels so as to encompass the upper opening. Finally, the bottom closure is connected to the opposing face and the opposing side panels so as to encompass the lower opening. Upon final assembly, the panels combine to define an internal storage region for containing the particulate-type product.

Canister with adhered paper layers for a particulate-type product

A canister for containing a particulate-type product. The canister includes at least one side wall, a top closure and a bottom closure. The side wall defines at least a portion of an internal storage region having an upper opening and a lower opening. The side wall includes a first paper-based layer, a second layer and an adhesive. The first layer includes a main body portion and a premium. The body portion and the premium are integrally formed such that the premium is selectively detachable from the body portion. The body portion and the premium each define an inner surface and an outer surface. The second layer has an inner surface and an outer surface. The adhesive bonds the inner surface of the body portion to the outer surface of the second layer, but does not impede detachment of the premium from the body portion. The top closure is connected to the side wall to encompass the upper opening. The bottom closure is connected to the side wall so as to encompass the lower opening. With this configuration, the second layer maintains a structural integrity of the canister upon detachment of the premium.

Canister with detachable premium for containing a particulate-type product

A canister for containing a particulate-type product. The canister includes a canister body and a plurality of microholes formed in the canister body. Other than the plurality of microholes, the canister body is hermetically sealed. In this regard, the canister body defines an internal storage region configured to contain a particulate-type product. The plurality of microholes are sized to allow passage of air from the internal storage region, as well as to limit passage of the particulate-type product. During use, a decrease in atmospheric pressure applied to the canister, such as during shipping, results in air being vented from the internal storage region via the plurality of microholes. Due to this air flow, an internal pressure of the canister body maintains substantial equilibrium with atmospheric pressure such that the canister body will not expand.
