Abstract
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.
