A container comprising: a container body for containing a product and having an open top, the container body having a generally horizontal annular ledge extending completely around the outer periphery of the open top, and a top edge surrounding the annular ledge, and an overcap which covers the open top and includes a skirt extending over the top edge of the container body around the circumference thereof and securely engages a side of the container body, said overcap further comprising a wall member extending downwardly and engaging the ledge completely around the open top, a bottom of the wall member flexing radially outwardly as it engages the ledge, the resiliency of the flexed wall member as it engages the ledge and its radially outward angle being such that the engagement of the bottom of the wall member and the ledge substantially prevent the ingress of air into the container while allowing gases located within the container to vent outwardly to the exterior.
