Claim:
A container with gas release feature, the container comprising: a rigid or semi-rigid container body having a bottom wall, a side wall extending upwardly from the bottom wall, and a neck of smaller diameter than the side wall, an upper portion of the side wall defining a shoulder forming a transition between the side wall and the neck, the shoulder decreasing in diameter in an upward direction toward the neck, the neck terminating at an upper edge encircling an opening of the container body; a removable closure affixed to the upper edge in a substantially gas-tight manner, the upper edge and the closure being configured to render the closure replaceable by re-engaging the closure with the upper edge for re-closing the opening after initial removal of the closure; and a gas release valve in the shoulder of the container body and operable to release gas from the container when the pressure differential between the interior and the exterior of the container is sufficient to open the valve.
