<P>PROBLEM TO BE SOLVED: To provide an inner plug for dispensing solid agents one by one without allowing a finger to making contact with a passage through which the solid agents pass, and easily manufactured. <P>SOLUTION: An outwardly stop flange 3 is formed on the upper end of a short cylindrical body 2, and an inwardly inner flange 4b is formed on the inner side of the short cylindrical body 2. Four expandable valve elements 4 are integrated with the inner flange 4b along its inner circumference. A slit 6 narrower than the outside diameter of solid agents 10 is formed in a cruciform on a boundary of the valve element 4 and the valve element 4. These valve elements 4 are inclined inwardly toward the center of the short cylindrical body, and a solid agent guiding part 4c is formed inside the valve element 4. A solid agent take-out port 4d having a size smaller than the outside diameter of the solid agent 10 is formed from four apexes of these triangular valve elements 4. Base ends of two strip-like operation pieces 5 located above the slit 6 and arrayed in the diameter direction of the short cylindrical body 2 are connected to the short cylindrical body 2, and the other ends are connected to the apexes of the two valve elements 4 adjacent to each other. <P>COPYRIGHT: (C)2011,JPO&INPIT |
