Abstract
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.
