A system for releasing a contained volume of gas. The system has a base with a pressure-release vent positioned within a flex region and a seal to disengagably seal the pressure-release vent. The seal has a gas vent path that extends from the pressure-release vent. The contained volume of gas passes through the gas vent path to apply force against the flex region and disengage the seal from the pressure-release vent, allowing the gas to exit through the pressure-release vent.
