As described above, the thin tongue piece 13a is provided on the front side and the back side of the inner annular wall 13, and extends downward along the inner annular wall 13 before the fixing plate 10 is attached to the mounting cup 1b. Is. Here, the upper projection 1d of the mounting cup 1b and the inner annular wall 13 of the fixed plate 10 fitted to the upper cup 1b have a track shape in plan view, so that the fixed plate 10 is viewed from above the mounting cup 1b. When approaching each other, when the directions of each other match, the fixed platen 10 is lowered to a height at which the lower end of the thin tongue 13a abuts against the upper surface of the middle projection 1e. In other words, the tip of the thin tongue 13a is in contact with the upper surface of the upper projection 1d and is positioned higher than a predetermined height. That is, since it is possible to determine whether or not the directions of both are in accordance with the difference in height of the fixed platen 10, the assembling work becomes easier. Further, when the fixed platen 10 is rotated, the fixed platen 10 moves downward when both directions are matched, so that it is possible to know the completion of the alignment with a tactile sense. Thereafter, when the fixed platen 10 is pushed in, the thin tongue 13a is bent outward as shown in FIG. 2, and the convex portion 15b engages with the lower concave portion 1h.

  Next, the cover member 20 is pressed from above in a state where the claw portion 26 is aligned with the engagement hole 18, and is attached to the stationary platen 10. Here, since the claw portion 26 is provided with the inclined surface 26a, when the cover member 20 is pressed against the fixed platen 10, the claw portion 26 is guided to the inclined surface 26a and bends inward so that it can be easily attached. Can do. Further, since the flange 25 of the cover member 20 is brought into contact with the step portion 16 of the fixed platen 10 after the mounting is completed, the cover member 20 is stably held on the fixed platen 10.

  Thereafter, the shaft portion 32 a of the lever 30 is inserted into the receiving portion 22 a of the cover member 20. As shown in FIG. 3, since the shaft portion 32a is provided with the inclined surface 32b, when the lever 30 is pressed against the cover member 20 from above, the side wall 32 connected to the shaft portion 32a is guided to the inclined surface 32b. Since it bends inward, it can be easily attached.

  After that, as shown in FIG. 5, the lever 30 is displaced (upwardly displaced) away from the mounting cup 1b, and the dispensing cylinder 43d is inserted from the side where the engagement wall 31b is provided with respect to the opening 31a. . In this embodiment, the inner peripheral surface of the engaging wall 31b and the outer peripheral surface of the dispensing cylinder 43d are provided with a convex portion p and a concave portion d that are engaged with each other, and the nozzle 40 is detachably held on the engaging wall 31b. The In addition, the convex part p may be intermittent and may be provided interchangeably. In addition, as shown in FIG. 2, by inserting the nozzle 40 to the end, the lower end of the engagement wall 31 b and the lower end of the reinforcing rib 34 are in contact with the box-shaped portion 43 a of the nozzle 40.

  Thereafter, the connecting cylinder portion 42b of the nozzle 40 can be inserted into the stem 1c by displacing the lever 30 in a direction approaching the mounting cup 1b (downward displacement). As shown in FIG. 2, attaching the overcap 50 to the cover member 20 effectively prevents dust and dirt from adhering to the nozzle 40 and the like.

  In addition, the attachment method mentioned above is only one illustration, and the order of attachment can be interchanged. For example, the cover member 20, the lever 30, the nozzle 40, and the overcap 50 may be assembled in advance on the stationary platen 10 to form the actuator 2 </ b> A, which may be attached to the container 1.

  In order to discharge the contents from the aerosol container 1 to which each member is attached in this manner, as shown in FIG. 6, a finger is applied to the operation portion 31d of the lever 30 and pressed toward the mounting cup 1b. As a result, the lever 30 swings around the shaft portion 32a and pushes down the two stems 1c together with the nozzle 40 by the engaging wall 31b and the reinforcing rib 34 (see FIG. 3). As a result, the two types of contents in the container 1 are simultaneously ejected from the respective stems 1 c and discharged from the discharge port 43 c through the passage R formed inside the nozzle 40. In addition, since the distance to the operation part 31d with respect to the axial part 32a is longer than the distance to the engagement wall 31b which presses the nozzle 40, or the reinforcement rib 34, the contents can be removed with a smaller force by the lever principle. It can be discharged.

  Depending on the type of content, the content remaining in the nozzle 40 may solidify, but in the actuator 2A of the present embodiment, the engagement wall 31b and the engagement wall 31b are more than the fitting force between the connection cylinder portion 42b and the stem 1c. Since the fitting force with the extraction cylinder 43d is increased, the nozzle 40 can be detached from the stem 1c only by moving the lever 30 upward as shown in FIG. Further, in the nozzle 40 of the present embodiment, since the dispensing cylinder 43d is a vertical type and the through hole 42c is provided on the central axis of the dispensing cylinder 43d, for example, a thin rod-shaped cleaning tool is used. Even when the nozzle 40 is held by the lever 30, the solidified contents in the nozzle 40 can be removed. Further, the nozzle 40 can be removed from the lever 30, and the lower member 42 and the upper member 43 of the nozzle 40 can be opened away from each other, so that the passage R can be easily cleaned. it can.
