<P>PROBLEM TO BE SOLVED: To prevent a pull-ring from largely deforming slantly upward or downward. <P>SOLUTION: A synthetic resin-made container inner plug has an outward flange 4 at the upper end of a peripheral wall 3 standing from the outer periphery of a bottom wall 2 and is structured by laterally providing the pull-ring 6 at the upper end of a support lever 5 standing from the upper surface of the outer periphery of the bottom wall 2. The peripheral wall of the inner plug is tightly fitted into a mouth of a container body. Thus a bottom wall part 2a having the support lever 5 with the pull-ring 6 standing is formed to be an upwardly or downwardly curved plate or a slope by the reduction of the diameter of the inner plug peripheral wall. <P>COPYRIGHT: (C)2004,JPO |
