Next, the usage mode and the action and effect of this example will be described.
First, in order to attach the screw cap of this embodiment to the container body A, the cap C is screwed into the inner plug B and tightened, the inner plug B and the cap C are set, and then the inner plug B is attached to the mouth 1. The fitting cylinder portion 4 of the above is applied and the stopper is formed from above.

When the female screw 55 of the screw cylinder portion 44 of the cap body C1 is screwed into the male screw 20 of the screw peripheral wall 8 of the inner plug B and tightened, the cap C rotates and the engaging arm of the inner peripheral wall 43 of the cap body C1. The 51 rides on the non-engaging surface 19 of the engaging protrusion 16 of the plug body 13 of the inner plug B, gets over the engaging protrusion 16, and allows the cap C to rotate.

Further, as the cap C is lowered, the second engaging protrusion 50 of the engaging portion 42 of the cap body C1 gets over the first engaging protrusion 17 of the plug body 13 of the inner plug B, and the tubular wall 14 It comes to fit on the inner peripheral surface.
At the same time, the wedge-shaped recess 56 at the lower part of the screw cylinder portion 44 comes to be fitted to the stopper 24 of the lower upper wall 7 of the inner plug B, and further, as the male screw 20 and the female screw 55 are fastened, the wedge-shaped recess 56 is formed. The second contact surface 56a of the recess 56 comes into contact with the first contact surface 24a of the stopper 24, and the fastening of both screws is completed.
Further, the sealing ring C2 is fitted on the outer circumference of the outer cylinder 5 of the inner plug B, and the cap C is set on the inner plug B.

Before the fastening of both screws is completed, as shown in FIGS. 5A and 6A, the vibration piece 58 of each sound producing member 45 of the cap body C1 is caused by the rotation and lowering of the cap body C1. When the tip abuts on each sound output protrusion 23 of the upper wall 9 of the inner plug B and the rotation progresses further, as shown in FIG. 6B, the vibrating piece 58 advances while being curved and deformed, and finally. As shown in FIGS. 1 (a) and 5 (b), the tip of the vibrating piece 58 gets over the sound output protrusion 23.
When the tip of the vibrating piece 58 gets over the sound emitting protrusion 23, the curved and deformed vibrating piece 58 tries to be restored, vibrates, and a sound is emitted.
From this sound, the user of the present invention can intuitively know the end of closing the cap.

After the screw cap of this embodiment assembled in the set state is plugged into the container body A, the sealing ring C2 is fixed to the outer cylinder 5 of the inner plug B, so that when the cap body C1 is rotated in the screwing direction. Since the weakened connecting portion 59 that connects the cap body C1 and the sealing ring C2 is broken, the opening status can be easily visually confirmed and the opening due to mischief or the like can be prevented.

Next, in order to use the container to which the screw cap of this embodiment is attached, the cap body C1 is rotated with respect to the inner plug B in the screwing direction.
When the cap body C1 is rotated, first, the weakened connecting portion 59 that connects the cap body C1 and the sealing ring C2 is broken, and the cap body C1 rotates.
Further, when the weakened connecting portion 59 is broken, a breaking sound is heard.

After that, as the rotation progresses, as shown in FIG. 6C, the tip of the vibrating piece 58 of the sound emitting member 45 of the cap body C1 comes into contact with the sound emitting protrusion 23 of the upper upper wall 9 of the inner plug B. As the rotation further progresses, the vibrating piece 58 advances while being curved and deformed, the tip of the vibrating piece 58 gets over the sound output protrusion 23, and the curved and deformed vibrating piece 58 is restored and vibrates, and a sound is emitted.

When further rotated, the engaging arm 51 extending from the inner peripheral surface of the inner peripheral wall 43 of the cap body C1 rotates, and the second engaging surface 52 of the tip engaging portion 53 engages with the plug body 13 of the inner plug B. It comes into contact with the first engaging surface 18 of the joint protrusion 16, and the rotational force of the cap body C1 is applied to the plug body 13 via the ratchet mechanism.
Since the tip engaging portion 53 of the engaging arm 51 is formed to be thicker than the arm portion 54, the second engaging surface 52 firmly contacts and engages with the first engaging surface 18 over a wide area and rotates. Has strength that is not defeated by force.

At this time, since the second engaging protrusion 50 of the engaging portion 42 is tightly fitted to the inner peripheral surface of the tubular wall 14, the tubular wall 14 is reinforced from the inside to reinforce the rotational force of the cap body C1. Is easily transmitted to the plug body 13 via the ratchet mechanism, and a force is generated to pull the plug body 13 upward as the screw rotates.
As the rotation of the cap body C1 progresses, the thinning weakening portion 12 is finally broken by the rotational force and the pulling force applied to the plug body 13, and the pouring outlet is opened in the pouring cylinder 11, and the pouring outlet is opened from the pouring cylinder portion 10. The separated plug body 13 is pulled up by the engaging portion 42 that engages with the tubular wall 14, and rises together with the cap body C1.
Further, when the thin-walled weakened portion 12 is broken, a breaking sound is heard.

Further, when the female screw 55 is screwed out from the male screw 20 and the cap body C1 is separated from the inner plug B as shown in FIG. 7, the opening of the pouring cylinder portion 10 from which the cap body 13 is removed together with the cap body C1. The contents in the container can be poured out from.

When the lid of the screw cap of the present invention is opened, a breaking sound of breaking the weakened connecting portion 59, a breaking sound of the vibrating piece 58 vibrating, and a breaking sound of breaking the thin-walled weakened portion 12 are emitted three times. Therefore, the user of the present invention can more intuitively know the state of opening the cap.
Further, the vibrating piece 58 and the sound output protrusion 23 are provided at three places each on the cap body C1 and the inner plug B, and the sound can be made even louder because the sound is emitted at substantially three places at the same time.
In this embodiment, when the lid is opened, a breaking sound of the weakened connecting portion 59, a sound emitted by the vibration piece 58 vibrating, and a breaking sound of the thin-walled weakened portion 12 are emitted in three times, but all of them are emitted. Sounds may be emitted at about the same time.
Further, only the sound generated by the vibration piece 58 vibrating, there is no breaking sound of the weakened connecting portion 59 and the thin-walled weakened portion 12, and only a click feeling may be used.

When the cap body C1 is screwed into the inner plug B again after the contents are poured out, the outer circumference of the inner peripheral wall 43 of the cap body C1 is in close contact with the inner circumference of the dispensing cylinder 11 to seal the inside of the container. Can be done.

Further, when the fastening of both screws is completed, the tip of the vibrating piece 58 of the sound producing member 45 abuts on the sound producing protrusion 23 and vibrates again, so that the user of the present invention emits a sound. , You can intuitively know the end of closing the cap.
Since the user of the present invention can intuitively know the end of closing the cap, the cap body C1 is forcibly rotated with respect to the inner plug B, the screwing becomes too strong, and the lid is opened. It is possible to prevent having trouble with.

When the inner plug B of the pouring cap of this embodiment is disposed of after using the container, it can be separated from the container main body A by a simple operation, separated and disposed of.
First, when a finger is put on the hook portion 31 near the vertical cutting portion 30 shown in FIGS. 2 and 3 and the grip portion 29 is pulled toward the front, the vertical cutting portion 30 is broken and the grip portion 29 expands outward.
When the grip portion 29 is further pulled while gripping the grip uneven portion 32 with a finger, the thin-walled start cutting portion 33 provided adjacent to the end portion 28b of the through slit 28 is broken, and the break is broken into the circumferential cutting portion 34. Go ahead.

When the circumferential cutting portion 34 is broken, the engagement of the locking reduced diameter portion 26 with the locking ridge 2 is released, so that the restraint on the mouth portion 1 by the locking reduced diameter portion 26 is released. When the grip portion 29 is pulled up, the inner plug B can be separated from the container body A and separately discarded.

In this embodiment, the male screw 20 and the female screw 55 are set to three threads in order to reduce the rotation angle for screwing the cap body C1, but if the range of rotation is not a concern, the three threads are used. Instead, it may be a single or multiple number of threads.

In this embodiment, the sound output protrusion 23 of the inner plug B and the sound output member 45 of the cap body C1 are arranged at three places at 120 ° intervals in accordance with the three-threaded screw, and when opening and closing. , Sound is emitted at almost three places at the same time to make the sound louder, but if it is not necessary to make the sound louder separately, either the sound emitting member 45 or the sound emitting protrusion 23 is provided at one or more places, and the rotation is about to end. It suffices to engage with any one or more places so that the sound producing member 45 emits sound.
Further, the number and the arrangement location of the sound producing member 45 and the sound producing protrusion 23 may be determined according to the type of the screw.
The number and arrangement points of the sound output member and the sound output protrusion are not limited to the embodiment of the present embodiment.

In this embodiment, the inner plug B and the cap body C1 are provided with a stopper 24 and a wedge-shaped recess 56 in order to stop the rotation after the lid is closed. However, when the lid is closed, the sound emitting member 45 makes a sound. Since the user can intuitively know the end of closing the cap, the user is forced to rotate too much and the screwing becomes too strong even if the stopper 24 and the wedge-shaped recess 56 are not provided. Can be prevented.

In this embodiment, a sound output protrusion 23 is provided on the upper surface of the upper upper wall 9 of the inner plug B, and sound is output between the inner peripheral wall 43 and the screw cylinder portion 44 on the lower surface of the top wall 40 of the cap body C1.
