  In the present embodiment, the biasing force of the operating body side coil spring 50 is set smaller than the biasing force of the pump side coil spring 26.

  According to such a configuration, the urging force of the operating body side coil spring 50 is obtained by bringing the application member 60 into contact with the push-down member 27 of the pump 20 from the state where the operating body 70 is removed from the container body 30 as shown in FIG. When the cover member 40 is pushed down against the above, the operating body side locking projection 43 provided on the inner peripheral surface of the cylindrical wall 42 of the cover member 40 is applied to the pump side locking projection 27f of the peripheral wall portion 27e of the pressing member 27 from above. The operation body 70 can be attached to the container main body 30 as shown in FIG. In this way, the operating body side locking projection 43 is retained and locked by the pump side locking projection 27f, thereby reliably preventing the operating body 70 from dropping from the container body 30 before the content liquid is discharged. Can do.

  Next, when the cover member 40 of the operating body 70 is used as an operating portion for pressing down the stem 23 and the cover member 40 is further pressed down as shown in FIG. 2, the urging force of the operating body side coil spring 50 is changed to the pump side coil spring 26. Therefore, first, the operating body side locking projection 43 can be fitted over the outer peripheral surface of the ring body 29 by getting over the convex portion 29a of the ring body 29 from above. .

  When the cover member 40 is further pushed down, the push-down member 27 is pushed down against the urging force of the pump-side coil spring 26 by the application member 60, and the content liquid in the cylinder portion 21d is separated from the vertical groove 23b of the stem 23, the piston. The material can be discharged from the discharge hole 27 c through the gap between the inner cylinder 24 a of the member 24 and the cylinder portion 23 c of the stem 23 and the through hole 23 d of the stem 23, and can be infiltrated into the applicator 61.

  When the depression is released in this state, as shown in FIG. 3, the operating body side locking projection 43 moves upward together with the ring body 29 by the biasing force of the operating body side coil spring 50, and the operating body side locking projection 43 is moved. The pump side locking projection 27f can be pulled out upward. That is, the operating body 70 can be easily detached from the container body 30 with a slight force that the operating body-side locking projection 43 just climbs over the convex portion 29 a of the ring body 29.

  When the depression is released, the stem 23 is returned upward by the urging force of the pump side coil spring 26. At this time, the upper surface of the projection 23a of the stem 23 is liquid-tight with the lower end outer peripheral surface of the inner cylinder 24a of the piston member 24. Since the stem 23 returns to the upper side while being in contact with the cylinder, the pressure in the cylinder portion 21d is reduced, the suction valve 22 is opened, and the liquid content is sucked up from the suction tube 21h into the cylinder portion 21d. As shown in FIG. 1, the negative pressure in the container member 34 is prevented.

  Although not provided in the present embodiment, it is preferable to provide a configuration that prevents unintended depression of the pump 20 when not in use as shown in FIG. For example, an overcap attached to the container body 30 in a state where the operation body 70 attached to the container body 30 is covered is provided, or the operation body 70 is connected to the container body 30 between the operation body 70 and the container body 30. Thus, it is possible to provide a lock mechanism that makes it impossible to push down the operating body 70 by rotating around the axis O.

  The above description shows only one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, the pump 20 is not limited to the one shown in the figure, and a pump shown in Patent Document 1 or other types can be adopted.
