  When discharging the contents, as shown in FIG. 5, the operation piece 68 is pushed down to swing and displace downward with the second hinge portion 67 as a fulcrum. The convex portion 69 of the pressed operation piece 68 contacts the concave portion 34 of the nozzle body 3, and the nozzle body 3 is pushed down. The nozzle body 3 is integrated with the discharge cylinder support portion 65 downward with the first hinge portion 64 as a fulcrum. Oscillating displacement causes the stem 25 to be pushed downward. When the stem 25 is pushed down, the contents in the container main body 21 are discharged from the tip of the discharge cylinder 31 via the stem 25 and the flow path inside the nozzle body 3.

  In the discharge tool 1 having the above-described configuration, the operation piece 68 oscillates with the second hinge portion 67 provided separately from the first hinge portion 64 serving as a fulcrum for the oscillation displacement of the nozzle body 3 as a fulcrum. With this configuration, the nozzle body 3 and the operation piece 68 can swing independently, and the operation piece 68 can be pushed down smoothly. Thereby, it is easy to push down the nozzle body 3 and the stem 25 when discharging the contents. In particular, in the case of having two stems 25 as in the aerosol container 2 of the present embodiment, the two stems 25 can be pushed down at the same time, and the contents can be easily balanced from the two stems 25 with an appropriate balance. Can be discharged.

The discharge tool 100 has a point R in which the distance L3 in the front-rear direction from the hinge part P serving as a fulcrum to the point Q serving as an action point (the point at which the pressing force from the operation piece 168 is applied to the nozzle body 103) is the point R from the point Q. Is equivalent to the distance L4 in the front-rear direction.

  On the other hand, in the discharge device 1 of the present embodiment shown in FIG. 6A, the second hinge portion 67 is disposed rearward of the first hinge portion 64, so that FIG. As shown in FIG. 4, the front-rear direction distance L1 from the second hinge part 67 to the point D (the contact point between the convex part 69 and the concave part 34) as the action point is the front-rear direction distance L2 from the point D to the point E as the power point. Is smaller than With such a configuration, it is possible to reduce the force applied to the operation piece 68 that is required when the stem 25 is pushed down based on the principle of the lever. That is, it is possible to easily push down the stem 25 and discharge the contents even with a small force. For example, when the distance L3, the distance L4, and the distance L2 shown in FIGS. 6A and 6B are equal and the distance L1 is 0.6 times the distance L2, the discharge tool 1 shown in FIG. The pressing-down force becomes 75% of the pressing force required for the discharge tool 100 shown in FIG.

  Moreover, in the discharge tool 1 of this embodiment, the pressing force required to discharge the contents is adjusted by adjusting the distance L1 by shifting the position of the second hinge portion 67 in the front-rear direction. be able to.

  Further, in the ejection tool 1 of the present embodiment, a pressing force is applied to the operation piece 68 by providing the convex portion 69 and the concave portion 34 at a position that is intermediate between the two stems 25 in plan view. Even when the position is shifted left and right, it is possible to apply a pressing force evenly to each stem 25. As a result, the operations of the nozzle body 3 and the stem 25 are stabilized, and the push-down amounts of the two types of stems 25 are less likely to vary, and the balance of the contents discharged from each stem 25 can be further stabilized. In particular, when the pressing force on the operation piece 68 is small, the discharge amount tends to become unstable. However, according to the present invention, the stem 25 is easily pushed down smoothly, so that the balance of the appropriate discharge amount from each stem 25 is achieved. The contents can be discharged.
