an impermeable container wall defining the boundaries of an inner volume of the container;
a container releasing valve installed in the container wall to release gas from the inner volume of the container to the outside of the container;
a gas vessel installed in the inner volume of the container, wherein the gas vessel comprises:
a gas vessel wall defining the boundaries of an inner volume of the gas vessel, wherein the gas vessel wall is impermeable and allows for a pressure difference between the inner volume of the gas vessel and an outer volume of the gas vessel;
a pressurized vessel gas enclosed within the inner volume of the gas vessel; and
a gas vessel releasing system to release a certain quantity of the vessel gas to the inner volume of the container;

a vessel sensor installed in the inner volume of the gas vessel to determine the presence of the vessel gas within the inner volume of the gas vessel;
a user indicator to announce a user that no vessel gas is present in the gas vessel; and
a controller coupled to the vessel sensor and the user indicator, the controller is to:
instruct the vessel sensor to determine the presence of the vessel gas within the inner volume of the gas vessel, and
instruct the user indicator to announce the user that no vessel gas is present in the gas vessel when the sensor determines that there is no vessel gas present in the gas vessel.
