[0006]

When the sliding member 12 is lifted from the state shown in FIG. 1 with respect to the container body 1 using the finger hook 19, the space inside the sliding member is enlarged as shown in FIG. The body fluid passes below the measuring chamber formed by the sliding member and the inner cylinder member 4 through the suction pipe 11 and the pouring cylinder 6. When the sliding member is released from this state, the sliding member descends as shown in FIG. 1 due to the elastic restoration of the compression coil spring 25, and the high pressure in the measuring chamber due to the descending causes much of the air above the chamber to enter the container. The liquid that has been press-fitted and sucked up remains in the measuring chamber. From this state, the container body is turned down, the tip of the application rod 29 is abutted against the surface to be applied, and the abutting is repeated, so that a small amount of liquid can be adhered to the surface to be applied until the liquid in the measuring chamber runs out. .

[0015]

[Effect of the Invention] Since the present invention has the above-described configuration, the inner cylindrical member 4
A measuring chamber is formed between the upper part and the inner surface of the sliding member 12, and a certain amount of liquid is measured in the measuring chamber by the vertical movement of the sliding member 12, and the discharging cylinder of the inner cylindrical member 4 is discharged. 6 Since the upper end is provided so that the upper wall 16 of the sliding member small cylinder is hermetically sealed, an outflow hole 18 is formed in the center of the top wall 17 of the sliding cylinder, and the outflow hole is pressed against the lower surface of the top wall. In addition to sealing with the plate 27, the application rod 29 was inserted from the center of the base plate into the outflow hole and the application rod 29 was projected outward, so that only the liquid in the measuring chamber could be applied by the operation of the application rod. As described above, the amount of the applied liquid is not unclear. In addition, since the small-diameter pouring cylinder 6 is erected from the upper end of the first guide cylindrical portion of the inner cylindrical member 4 via an inward flange, the liquid in the container enters the measuring chamber by pulling up the sliding member 12 with respect to the inner cylindrical member 4. When sucked, the sucked-up liquid is stored between the discharge cylinder 6 and the upper part of the sliding cylinder 13 of the sliding member 12, so that even if the sliding member is lowered from this state, it is sucked. The liquid does not return to the container again, only the air in the upper part of the measuring chamber is returned to the container, and the liquid sucked into the measuring chamber and the air in the measuring chamber can be reliably and easily replaced. I can do it.
