<P>PROBLEM TO BE SOLVED: To provide a tube-type container that can be filled with liquid contents irrespective of the magnitude of viscosity, restrict air flowing inside the container when the liquid contents filled into the tubular container are used, and thus prevent changes in the physical property of the liquid contents. <P>SOLUTION: The container includes: wings inwardly protrudingly formed on the inner wall of the discharge cap and regularly spaced apart from each other so that a space is formed between the wings; a fixing part fitted into the wings, operating part configured such that its upper end is inserted into the fixing part and its lower end forms a closing tube for closing the passage; and a spring placed between the operating part and the fixing part and used to bias the operating section toward the passage. <P>COPYRIGHT: (C)2010,JPO&INPIT |
