<P>PROBLEM TO BE SOLVED: To provide a tube container which holds a gas-discharging content while acquiring improved quality and stability and reducing costs. <P>SOLUTION: A gas exhausting structure comprises the tube container 1 which holds the content that discharges a gas when subjected to a secular change, a cap 3 attached to a nozzle 2 of the container 1, and a gas-permeable packing 4 which is arranged inside the cap 3. The packing 4 is made into a disc shape that covers the entire top face of the nozzle 2, and has a gas permeability that allows a gas discharged from the content to pass through the packing 4 but blocks the content's exit. The cap 3 has a support wall 3b that supports the packing 4 from above, sticking the periphery of the packing 4 closely to the top face of the nozzle 2 to prevent the content from leaking out of the packing periphery. The support wall 3b has an exhaust hole 5, which allows the gas passing through the packing 4 to escape to the outside, thus leads the gas discharged from the content to pass out upward directly through the discharge opening. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
