A container for a product which off-gases comprising: (a) a container body with a sidewall and a mouth at its upper end bounded by a lip and having an outwardly extending shoulder adjacent the upper end of the sidewall and below the lip; (b) a seal extending over said mouth and adhered to said lip, said seal having a valve therein permitting gases in said container body to exit there through; and (c) a cap having a top wall and a depending skirt defined by at least an inner wall and an outer wall with an internal peripheral snap bead located and configured to abut the lower surface of the shoulder on the sidewall of the container body, the bottom surface of said top wall of said cap having a depending flexible ring seal bearing on said lip, said cap having at least one channel in the inner wall extending downwardly through the skirt without extending through said outer wall; whereby gas pressure in the container body will cause said valve in said seal to release gas from the interior of the container body into the space in the cap above said seal and the pressure of the gas in the space lifts said ring seal from said lip to allow the gas to flow thereby and outwardly in the at least one channel in the cap and discharge to the atmosphere.
