Abstract: A method and a container for long-term storage in a state in which harmful insects do not propagate, in a case in which grains such as unpolished rice or the like are filled and stored. An inner bag (10) made of a flexible material is accommodated in an outer bag (12) which has high-strength. After grains are filled in the inner bag, the inner bag (10) is filled with carbon dioxide gas and is closed. The grains are stored in a state in which harmful insects are exterminated. It is preferable from the standpoint of the insecticidal effect that the inner portion of the inner bag (10) is able to maintain a carbon dioxide gas concentration of 40% or more for 7 days or more. Because the inner bag has the property of a CO.sub.2 permeation amount of less than or equal to 6300 cc/m.sup.2 .multidot.24 hr 1 atm, an oxygen-deficient state can be maintained.

Abstract: A method for filling gas release valves with sealant for affixing to packaging containers to be filled with a commodity which will generate a small amount of gases during shelf storage. The gas release valve having an apertured base film and a valve film superimposed on the base film to define a channel therebetween is attached to the container in registry with a vent in the container such that the valve may allow the gases given off by the commodity to escape to the exterior through the vent and the channel when the gas pressure rises beyond the atmospheric pressure. Before the gas release valve is attached to the container, the valve is sealed by inserting a nozzle into said channel through the aperture in the base film, and introducing a fluid sealant through the nozzle into the channel intermediate one peripheral edge of the channel and the circumference of the aperture, thereby filling the channel with the fluid sealant.
