  Then, by rotating the rotating cylinder 22 relative to the button body 24, the cylinder positioning mark 53 and the button positioning mark 54 are made to coincide with each other in the rotation direction of the rotating cylinder 22, and a plurality of engaging projections are formed. If the portions 45 are vertically aligned with the corresponding locking recesses 46, when the button body 24 is pressed downward in this state, as shown in FIG. Then, the plurality of engaging projections 45 are respectively engaged with the corresponding locking recesses 46.

When the rotary cylinder 22 is rotated in the cap loosening direction B in this state, the convex contact surface 50 and the concave contact surface 51 are brought into contact with each other as the rotary cylinder 22 rotates in the cap loosening direction B. When the button body 24 rotates in the cap loosening direction B, the inner cap 11 and the outer cap 12 can be detached from the mouth portion 3 to open the safety cap device 4.
At this time, in order to open the safety cap device 4, the button body 24 is simply rotated in the cap loosening direction B, and it is troublesome to turn the outer cap 12 in the cap loosening direction B while pressing the outer cap 12 downward as in the prior art. You don't have to do anything.

  Further, as shown in FIG. 5A, when the button body 24 is between the lower internal fitting position X and the upper internal fitting position Y, the plurality of button engagement mechanisms 43 are engaged, and the rotary cylinder As the body 22 rotates in the cap tightening direction A, the cap tightening direction rotational force that rotates the button body 24 in the cap tightening direction A and the button body 24 rises from the lower internal fit position X to the upper internal fit position Y. To produce power.

When the screwing is completed, the button body 24 is raised from the lower internal fitting position X to the upper internal fitting position Y.

Thus, when the button body 24 is between the lower internal fitting position X and the upper internal fitting position Y, the rotating cylinder 2
2 is rotated in the cap tightening direction A, the button body 24 is rotated in the cap tightening direction A, and the screwing of the inner cap 11 to the mouth 3 is completed or the mouth of the inner cap 11 is completed. After the screwing to 3 is completed, the button body 24 can be raised from the lower internal fitting position X to the upper internal fitting position Y.

Then, as shown in FIG. 5B, since the button engagement mechanism 43 is disengaged when the button body 24 is raised to the upper internal fitting position Y, the rotating cylinder 22 is moved in the cap loosening direction B in this state. , The rotational force is not transmitted to the button body 24, and the rotating cylinder 22 idles in the cap loosening direction B with respect to the button body 24.
Accordingly, when the button body 24 is raised from the lower inner fitting position X to the upper inner fitting position Y, the rotary cylinder 22 is idled in the cap loosening direction B with respect to the button body 24, and an infant or the like can easily open the cap. It is possible to easily confirm with the eyes that it is no longer possible. As a result, since it is difficult to understand when the screwing of the inner cap 11 to the mouth part 3 is completed as in the conventional case, the screwing of the rotary cylinder 22 before the screwing of the inner cap 11 to the mouth part 3 is completed. By stopping the rotation in the cap tightening direction A, the cap can be easily opened by an infant or the like, and the function of the safety cap device 4 can be reliably prevented from being impaired.

That is, when the button body 24 is between the upper internal fitting position Y and the raised position Z, the fastening engagement surfaces 60 and fastening fastening surfaces 62 of the plurality of fastening direction engaging mechanisms 65 can be engaged. The rotating cylinder 22 is opposed to the rotation direction of the rotary cylinder 22, and the button body 24 is rotated in the cap tightening direction A as the rotary cylinder 22 rotates in the cap tightening direction A. And screwing the inner cap 11 into the mouth 3 is completed.

Accordingly, by rotating the rotating cylinder 22 in the cap tightening direction A, even after the button body 24 is raised to the upper internal fitting position Y, the inner cylinder cap is maintained by rotating the rotating cylinder 22 slightly in the cap tightening direction A. 11 can be reliably completed.
Next, as shown in FIG. 6A, when the button body 24 is between the upper internal fitting position Y and the raised position Z, the loosening engagement portions 61 of the plural loosening direction engagement mechanisms 66 are loosened. When the rotating cylinder 22 is rotated in the cap loosening direction B, the loosening direction engaging mechanism 66 (relaxation engagement) is provided. The part 61 and the loose locking part 63) are engaged with each other, and the button body 24 is raised from the upper internal fitting position Y to the raised position Z as the rotating cylinder 22 rotates in the cap loosening direction B.

The fastening engagement surface 60 and the fastening engagement surface 62 (tightening direction engaging mechanism 65) are separated from each other in the vertical direction so that the rotary cylinder 22 cannot be engaged. Even if it rotates in the loosening direction B, the rotational force is not transmitted to the button body 24, and the rotating cylinder 22 turns idle in the cap tightening direction A and the cap loosening direction B (completely child locked) ).

Therefore, in this state, even if the child or the like tries to open the safety cap device 4 and rotates the rotating cylinder 22 in the cap loosening direction B and the cap tightening direction A, the rotating cylinder 22 rotates idle, and the safety cap device Can't open 4
At this time, if the button body 24 is pressed downward, the rotary cylinder 22 can be lowered from the ascending position Z to the upper internal fitting position Y. As described above, as long as the cylinder positioning mark 53 and the button positioning mark 54 do not coincide with each other in the rotation direction of the rotary cylinder 22, the button body 24 is not lowered from the upper fitting position Y to the lower fitting position X. In other words, the state (child lock) in which the rotating cylinder 22 idles in the cap loosening direction B with respect to the button body 24 is not released.
