By alternately adapting the length and position of 16 to the width and position of their cutouts 20, a non-engagement zone 17 that functions only in a predetermined direction in the horizontal plane of the shoulder cover 5 is formed between them,
The shoulder cover 5 can be pulled out upward.

The positioning means 10 is provided with a fan-shaped notch 21 on the upper surface of the rear part of the shoulder cover 5, and the base cylinder 4 is made to correspond to the notch.
An abutment protruding member 25 is erected from the rear upper end surface to face the notch portion 21, and in relation to the push-down ejection head lowering prevention means 8 and the shoulder cover removal means 9. ,
It is as follows. (1) When the shoulder cover 5 is rotated to one side in relation to the press-down ejection head lowering prevention means 8, the one side wall surface 22 of the cutout 21 abuts against the abutting projection 25, that is,
At the position shown as "OFF" in FIG. 1, the abutment tongue 14 abuts against the stopper 13 to prevent the downwardly ejecting head 6 from descending. When the other side wall surface 23 of the portion 21 abuts against the abutting projection 25, that is, at the position indicated by “ON” in FIG. 1, the abutment tongue 14 becomes free with respect to the stopper 13 and the ejection head is pushed down. 6 is set so that it can be lowered. (2) In relation to the shoulder cover extracting means 9, the shoulder cover 5
Is appropriately rotated so that the center 24 of the notch 21 is

With the above configuration, when the commodity is being distributed, the positioning means 10 is set to the lowering prevention state of the downwardly ejecting head in relation to the downwardly ejecting head lowering inhibiting means 8. That is, when the shoulder cover 5 is rotated clockwise in the state of FIG. 1 so that the position of “OFF” is aligned with the abutting projection 25, the push-down ejection head 6 also moves the thin hinge 11. As shown in FIG. 2, the abutment tongue 14 of the push-down ejection head 6 abuts against the stopper 13 of the base cylinder 4 to prevent the push-down ejection head 6 from descending. . Therefore, it is possible to prevent unnecessary ejection of the contents in the product distribution process. Of course, this can also be used by the consumer.

Next, when the consumer ejects the contents, the positioning means 10 is pushed down and the ejection head lowering preventing means 8 is pushed down.
Is set to a state where the press-down ejection head can be lowered. That is, when the shoulder cover 5 is rotated in the counterclockwise direction so that the position of "ON" is matched with the abutting projection 25 as shown in FIG. As shown in FIG. 2, the abutment tongue piece 14 comes off the position of the stopper 13,
The push-down ejection head 6 can be lowered. Therefore, in this state, if the pushing down ejection head 6 is pushed down, ejection of the contents can be obtained.

When the contents are used up and the aerosol container is to be discarded, the positioning means 10 is set in such a manner that the shoulder cover comes off in relation to the shoulder cover extracting means 9. That is, in the “OFF” and “ON” states of the push-down ejection head lowering prevention means 8, as shown in FIGS. 8A and 8B, the locking ridge 15 of the base cylinder 4 and the engaging ridge of the shoulder cover 5.
16 is in the engaged state, and the shoulder cover 5 cannot be pulled out. However, the shoulder cover 5 is rotated so that the center 24 (FIG. 1) of the notch 21 is aligned with the position of the abutting projection 25. At this time, as shown in FIG. 8C, the engaging ridge 16 of the shoulder cover 5 is located at the cutout portion 20 of the locking ridge 15 of the base cylinder 4, and at the same time, the locking ridge 15 of the base cylinder 4 is Is also located at the cutout 20 of the engaging ridge 16 of the shoulder cover 5,

In this case, in the first embodiment described above, only the rotation means 7 of the push-down ejection head 6 with the shoulder cover 5 is different. That is, the sub-rotation means 7 is formed by connecting the shoulder cover 5 and the press-down ejection head 6 at appropriate positions via the splines 12. In this case, however, the push-down ejection head 6 cannot be made to follow the shoulder cover 5 even if the shoulder cover 5 is pulled out because of the sub-rotation means 7 by the spline 12, so the push-down ejection head 6 needs to be pulled out separately. In addition, this means that the shoulder cover 5 is detached as a single member.
As shown in FIG. 5, the shoulder cover 5 is fitted to the upper part of the main cylinder 18 of the base cylinder 4 in an inverted state, so that the shoulder cover 5 can be used as a jig for removing the base cylinder. The other points are substantially the same as those in the first embodiment, and thus the description thereof is omitted here.
