Abstract: A packaging for containing a particulate product is disclose in preferred forms of a canister (10) and a bag (100). The packaging includes a body (11, 110) and at least one microhole (40, 400) formed in the body (11, 110). Other than the microhole(s) (40, 400), the body (11, 110) is hermetically sealed. In this regard, the body (11, 110) defines an internal storage region (20, 200) configured to contain a particulate product (22). The microhole(s) (40, 400) are sized to allow passage of air from the internal storage region (20, 200), as well as to limit passage of the particulate product (22). During use, a decrease in atmospheric pressure applied to the packaging, such as during shipping, results in air being vented from the internal storage region (20, 200) via the microhole(s) (40, 400). Due to this air flow, an internal pressure of the body (11, 110) maintains substantial equilibrium with atmospheric pressure such that the body (11, 110) will not unexpectedly expand or in the case of bag (100) burst.

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.
