Further, the inner plug 3 is formed with two grooves, an outer groove 6 and an inner groove 7, concentrically with the insertion hole 4, and the outer groove 6 has four partition walls 8a and 8b as shown in FIG. , 8b, 8b are divided into four smaller sections a, b, c and d. By the way, in this embodiment, the outer groove 6 is formed to have a width of about 1,3 mm and the inner groove 7 is formed to have a width of about 2 mm.

As shown in FIGS. 2 and 3, among the partition walls, the upper surface of the partition wall 8a is formed on the same surface as the surface of the inner plug 3, and the other partition wall 8b has a small notch formed on the upper surface thereof to form a communicating portion. 9 are formed, and the communication portion 9 communicates with each other except for the sections a and d. An inner hole 10 that communicates with the inside of the container body 1 is formed on the bottom surface of the partition a formed by the partition walls 8a and 8b, and a communication portion 11 is formed on the upper portion of the standing wall between the partition d and the inner groove 7. Is made. By the way, in this embodiment, the inner hole 10 has a diameter of about 1 mm.

A cap 12 is capped on the mouth portion 2 of the container body 1, and a bottom surface of the cap 12 and an upper surface of the inner plug 3 are in contact with each other. The cap 12 forms an outer groove 6 and an inner groove 7. Are isolated. An outer hole 13 is formed on the surface of the cap 12 with respect to the upper surface of the inner groove 7, as shown in FIG.

As described above, the inside of the container body 1 is, as shown in FIG. 3, an inner hole 10, a communicating portion 9 of each of the compartments a, b, c and d, and a communicating portion 11 of the compartment d and the inner groove 7.
