Abstract: The present invention provides a gas hermetic bag which can easily be shipped and produced, and in which a shape of the gas hermetic bag capable of protecting corner portions of an article is formed by supplying gas into the gas hermetic bag to expand the air hermetic bag, and which has protecting function suitable for protecting corner portions of articles having various sizes and shapes. In the gas hermetic bag, plastic films are superposed on each other and peripheries thereof are tightly closed by thermal welding and gas is charged into the gas hermetic bag. The gas hermetic bag 10? has a triangle pole shape in which a bottom surface thereof has an isosceles triangle Q shape and a side surface thereof has a rectangle shape, and a surface facing a vertex angle of the pole is opened.

Abstract: A method and apparatus for a fluid container having a plurality of container members and firmly sealing the fluid container to prevent reverse flows of fluid from the container members where each container member is not provided with a check valve. The fluid container includes a guide passage, a plurality of container members, and narrow passages connecting the guide passage and the container members, and a check-valve formed at an input of the guide passage for allowing a fluid flow of only one predetermined direction. A fluid is introduced through the input of the guide passage, the check-valve, and the narrow passages to the container members, thereby inflating the container members. The narrow passages are sealed after the inflation of the container members.
