PROBLEM TO BE SOLVED: To provide a tubular container having a seal stopper, capable of preventing the formation of a liquid membrane in the container opening when the seal stopper is removed. SOLUTION: The seal stopper 12 for sealing the opening of the tubular container 10 has a layer structure including an upper layer 26 and a lower layer 28. The lower layer 28 has an arch-shaped base 42 and a tongue part 44 extending from the edge that is a string of the arch. A holding piece 24 of the seal stopper is pulled up for opening the seal stopper 12. While the base 42 remains in the edge 20 of the tubular container, the tongue part 44 is positioned within the opening plane together with the base 42. When the holding piece 24 is pulled up more, the base 42 begins to be removed and the tongue part 44 is simultaneously moved from the opening plane. The tip end of the tongue part 44 moves the most, and uneven force is applied to the liquid membrane to break it. Thus, the formation of the liquid membrane is prevented. COPYRIGHT: (C)2011,JPO&INPIT
