Next, usage modes and operational effects of this embodiment will be described.
First, in order to attach the screw cap of the present embodiment to the container main body A, the cap C is screwed into the inner plug B and tightened. After setting the inner plug B and the cap C, the inner plug B is inserted into the mouth 1. The fitting tube part 4 is applied and plugged from above.

  When the female screw 55 of the screw cylinder portion 44 of the cap main 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 main body C1 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.

When the cap C is further 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 13 of the inner plug B, and the cylindrical wall 14 Fits to the inner peripheral surface.
At the same time, the wedge-shaped concave portion 56 at the lower part of the screw cylinder portion 44 is fitted into the stopper 24 of the lower upper wall 7 of the inner plug B, and further, when the fastening of the male screw 20 and the female screw 55 proceeds, the wedge shape The second contact surface 56a of the recess 56 contacts the first contact surface 24a of the stopper 24, and the fastening of both screws is completed.
Further, the sealing ring C2 is fitted to the outer periphery 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 pieces 58 of the sound output members 45 of the cap body C1 are rotated by the rotation and lowering of the cap body C1. When the tip comes into contact with each sound projecting protrusion 23 of the upper upper wall 9 of the inner plug B and the rotation further proceeds, as shown in FIG. As shown in FIGS. 1A and 5B, the tip of the vibrating piece 58 gets over the sound projecting protrusion 23.
When the tip of the vibrating piece 58 gets over the sound emitting projection 23, the curved vibrating piece 58 tries to recover, vibrates and emits a sound.
This sound allows the user of the present invention to know the end of cap closing sensuously.

  After the screw cap of this embodiment assembled in the set state is plugged into the container main body A, the sealing ring C2 is fixed to the outer cylinder 5 of the inner plug B. Therefore, when the cap main 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 state can be easily confirmed visually, and the opening due to mischief or the like can be prevented.

Next, in order to use the container equipped with the screw cap of this embodiment, 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 weakening connecting portion 59 that connects the cap body C1 and the sealing ring C2 is broken, and the cap body C1 is rotated.
Further, when the weakened connecting portion 59 is broken, a breaking sound is made.

  Thereafter, when the rotation proceeds, as shown in FIG. 6C, the tip of the vibrating piece 58 of the sound producing member 45 of the cap body C1 comes into contact with the sound producing protrusion 23 of the upper upper wall 9 of the inner plug B, As the rotation further proceeds, the vibrating piece 58 advances while being curved and deformed, the tip of the vibrating piece 58 gets over the sound emitting projection 23, 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. The first protrusion 18 comes into contact with the first engaging surface 18 of the mating protrusion 16, and the rotational force of the cap body C1 is applied to the plug body 13 via the ratchet mechanism.
Since the distal end engaging portion 53 of the engaging arm 51 is formed thicker than the arm portion 54, the second engaging surface 52 firmly contacts and engages with the first engaging surface 18 in a wide area and rotates. Has strength not to be 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 cylindrical wall 14, the cylindrical wall 14 is reinforced from the inside to rotate the cap body C1. Is easily transmitted to the plug body 13 via the ratchet mechanism, and generates a force for pulling up the plug body 13 as the screw rotates.
When the rotation of the cap main body C1 proceeds, the thinning weakened portion 12 is finally broken by the rotational force and the pulling force applied to the plug body 13, and the spout is opened in the spout tube 11, so that the spout tube portion 10 The separated plug body 13 is pulled up by the engaging portion 42 that engages with the cylindrical wall 14 and rises together with the cap body C1.
Further, when the thinned weakened portion 12 is broken, a breaking sound is made.

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

In the screw cap of the present invention, when the lid is opened, a breaking sound that breaks the weakening connecting portion 59, a sound that is generated by vibrating the vibration piece 58, a breaking sound that breaks the thinned weakening portion 12, and a three-time sound are emitted. Therefore, the user of the present invention can know the situation of opening the cap more sensuously.
Further, the vibrating piece 58 and the sound projecting protrusion 23 are provided at three locations on the cap body C1 and the inner plug B, respectively, and almost three locations emit sound at the same time, so that the sound can be further increased.
In the present embodiment, when the lid is opened, a sound is emitted in three times, a breaking sound of the weakening connecting portion 59, a sound emitted by vibrating the vibrating piece 58, and a breaking sound of the thinned weakening portion 12. Sounds may be emitted almost simultaneously.
Further, only the sound generated when the vibrating piece 58 vibrates, there is no breaking sound of the weakened connecting portion 59 and the thinned weakened portion 12, and only a click feeling may be used.

  When the cap main body C1 is screwed into the inner plug B again after the contents have been poured out, the outer periphery of the inner peripheral wall 43 of the cap main body C1 is in close contact with the inner periphery of the pouring cylinder 11, and the inside of the container is sealed. Can do.

Further, when the fastening of both screws is completed, the tip of the vibrating piece 58 of the sound producing member 45 again abuts against the sound producing protrusion 23 and vibrates to generate a sound. , You can sensuously know the end of cap closure.
Since the user of the present invention can sensuously know the end of the cap closing, the cap main body C1 is excessively rotated with respect to the inner plug B, the screwing becomes too strong, and the lid is opened. Can be prevented.

The inner cap B of the dispensing cap of the present embodiment can be separated from the container body A by a simple operation, separated and discarded when the container is used and then discarded.
First, when a finger is put on the hook 31 near the vertical cutting portion 30 shown in FIGS. 2 and 3 and the gripping portion 29 is pulled to the front, the vertical cutting portion 30 is broken and the gripping portion 29 is expanded outward.
When the gripping portion 29 is further pulled while the gripping uneven portion 32 is gripped with a finger, the thin-walled start portion 33 provided adjacent to the end portion 28 b of the through slit 28 is broken, and the circumferential cut portion 34 is broken. Go ahead.

  When the circumferential cut portion 34 is broken, the engagement of the engagement reduced diameter portion 26 with the engagement protrusion 2 is released, so that the restriction on the mouth 1 by the engagement reduced diameter portion 26 is released. When the grip portion 29 is pulled up, the inner stopper B can be separated from the container main body A and separated and discarded.

  In this embodiment, the male screw 20 and the female screw 55 are three-threaded to reduce the rotation angle for screwing the cap body C1, but if the screw does not care about the rotation range, the three-thread Instead, it may be a single or multiple threads.

In this embodiment, the sound emitting protrusion 23 of the inner plug B and the sound emitting member 45 of the cap body C1 are arranged at three positions at 120 ° intervals in accordance with the triple thread, and are opened and closed. The sound is emitted at almost three places at the same time to increase the sound. However, if it is not necessary to increase the sound separately, at least one of the sound output member 45 or the sound output protrusion 23 is provided, and the rotation is completed. The sound output member 45 may generate sound by engaging at least one of the above.
Further, the number and arrangement locations of the sound producing member 45 and the sound producing protrusion 23 may be determined in accordance with the type of screw.
The number of the sound emitting members and the sound emitting protrusions and the arrangement locations are not limited to the embodiment.

  In this embodiment, the stopper 24 and the wedge-shaped recess 56 are provided in the inner plug B and the cap body C1 in order to stop the rotation after the lid is closed. Therefore, the user can sensuously know that the cap has been closed, so that even if the stopper 24 and the wedge-shaped concave portion 56 are not provided, the user is forced to rotate too much and the screwing becomes too strong. This can be prevented.

In the present embodiment, a sound emitting projection 23 is disposed on the upper surface of the upper upper wall 9 of the inner plug B, and sound is emitted between the inner peripheral wall 43 on the lower surface of the top wall 40 of the cap body C1 and the screw cylinder portion 44.
