At the same time, the vibrating piece 58 is set to vibrate and generate sound by overcoming the sound output protrusion 41 and trying to restore it.

次に、本実施例の使用態様と作用効果について説明する。
本実施例の中栓付きボトルは、内容物が充填されたボトル本体Aの口筒部1に中栓Bを打栓して装着した後、ボトル本体Aに装着された中栓BにキャップCを螺合することにより、作業が完了する。
Next, the usage mode and the action and effect of this example will be described.
In the bottle with an inner plug of this embodiment, the inner plug B is plugged into the mouth cylinder portion 1 of the bottle body A filled with the contents and then attached, and then the cap C is attached to the inner plug B attached to the bottle body A. The work is completed by screwing.

打栓工程は、中栓Bの外筒11と内筒12と上壁13とで形成される嵌合筒部10にボトル本体Aの口筒部1を当てがい、中栓Bの上壁13の上から押圧力を加えることによって、図6に示すように、中栓Bは、外筒11の内周、内筒12の外周および上壁13とによって口筒部1を挟持することで嵌着する。
打栓の際に、口筒部1の内周面1aは、わずかに縮径してテーパ面が形成されていることにより、内筒12が嵌入し易くなり、かつ、口筒部1の嵌合突部4aよりもストレート部6の外径の方が大きいために、下部係止縮径部29が上部アンダーカット部4を乗り越え易くなっている。
In the tapping step, the mouth cylinder portion 1 of the bottle body A is applied to the fitting cylinder portion 10 formed by the outer cylinder 11, the inner cylinder 12, and the upper wall 13 of the inner plug B, and the upper wall 13 of the inner plug B is applied. By applying a pressing force from above, as shown in FIG. 6, the inner plug B is fitted by sandwiching the mouth cylinder portion 1 with the inner circumference of the outer cylinder 11, the outer circumference of the inner cylinder 12, and the upper wall 13. To wear.
At the time of tapping, the inner peripheral surface 1a of the mouth cylinder portion 1 is slightly reduced in diameter to form a tapered surface, so that the inner cylinder 12 can be easily fitted and the mouth cylinder portion 1 is fitted. Since the outer diameter of the straight portion 6 is larger than that of the collision portion 4a, the lower locking reduced diameter portion 29 can easily get over the upper undercut portion 4.

本実施例では、図2(a)に示すボトル本体Aがガラスボトルの場合に、口筒部1の外周面にストレート部6が形成されていることにより、中栓Bを打栓する際に、外筒11が膨らみ、雄ねじ27が変形することを防止できる。
さらに、ガラスボトルの場合には、中栓Bが口筒部1に対して空回りするおそれがあるが、本実施例では、上部係止縮径部28は、内筒12と協働して径方向の締め付け力を発揮し、また、下部係止縮径部29は、上壁13と協働して軸線方向の締め付け力を発揮することにより、中栓Bの嵌合強度を向上させることができ、口筒部1の外周面にリブ等を設けることなく、中栓Bの空回りを防止することができる。
In this embodiment, when the bottle body A shown in FIG. 2A is a glass bottle, the straight portion 6 is formed on the outer peripheral surface of the mouth cylinder portion 1, so that when the inner plug B is tapped. , It is possible to prevent the outer cylinder 11 from swelling and the male screw 27 from being deformed.
Further, in the case of a glass bottle, the inner plug B may idle with respect to the mouth cylinder portion 1, but in this embodiment, the upper locking reduced diameter portion 28 has a diameter in cooperation with the inner cylinder portion 12. The lower locking reduced diameter portion 29 exerts a tightening force in the direction and exerts a tightening force in the axial direction in cooperation with the upper wall 13, thereby improving the fitting strength of the inner plug B. It is possible to prevent the inner plug B from idling without providing a rib or the like on the outer peripheral surface of the mouthpiece portion 1.

また、図2(b)に示すボトル本体Aaが合成樹脂ボトルの場合に、口筒部1の外周面にネックリング8を形成することにより、中栓Bを打栓する際に、ボトル本体Aaの肩部7や胴部3が変形しないように、ネックリング8を治具(フォルダ)等により保持して口筒部1に打栓して装着することができる。 Further, when the bottle body Aa shown in FIG. 2B is a synthetic resin bottle, the bottle body Aa is formed when the inner plug B is plugged by forming the neck ring 8 on the outer peripheral surface of the mouth tube portion 1. The neck ring 8 can be held by a jig (folder) or the like and plugged into the mouth cylinder portion 1 so that the shoulder portion 7 and the body portion 3 are not deformed.

螺合工程では、キャップCのねじ筒部48の雌ねじ55を中栓Bの外筒11の雄ねじ27に螺合して締め込む際には、キャップCが回動し、キャップCの密封筒46の係合腕51は、中栓Bの栓体20の係合突起23の非係合面26に乗り上げ、係合突起23を乗り越えて、キャップCの回動を許容する。
さらにキャップCが下降することにより、キャップCの係着部45の第2係合突部50が中栓Bの栓体20の第1係合突部24を乗り越えて、筒状壁21の内周面に嵌合するようになる。
In the screwing step, when the female screw 55 of the screw cylinder portion 48 of the cap C is screwed into the male screw 27 of the outer cylinder 11 of the inner plug B and tightened, the cap C rotates and the sealing cylinder 46 of the cap C is used. The engaging arm 51 rides on the non-engaging surface 26 of the engaging protrusion 23 of the plug body 20 of the inner plug B, gets over the engaging protrusion 23, and allows the cap C to rotate.
Further, as the cap C is lowered, the second engaging protrusion 50 of the engaging portion 45 of the cap C gets over the first engaging protrusion 24 of the plug body 20 of the inner plug B, and is inside the tubular wall 21. It will fit on the peripheral surface.

雄ねじ27と雌ねじ55の締結が完了する前には、図1(b)に示すように、キャップCの回動および下降により、キャップCのそれぞれの音出し部材49の振動片58先端が、中栓Bのテーパ壁14のそれぞれの音出し突部41に当接し、さらに回動が進むと、振動片58が湾曲変形しながら進み、最後は、振動片58の先端が音出し突部41を乗り越える。
振動片58の先端が音出し突部41を乗り越えると、湾曲変形した振動片58が復元しようとし、振動し、音が発せられるので、この音により、本発明の利用者は、感覚的にキャップCの閉蓋終了を知ることができる。
Before the fastening of the male screw 27 and the female screw 55 is completed, as shown in FIG. 1 (b), the tip of the vibrating piece 58 of each sound producing member 49 of the cap C is middle due to the rotation and lowering of the cap C. When it comes into contact with each sound emitting protrusion 41 of the tapered wall 14 of the plug B and further rotates, the vibrating piece 58 advances while being curved and deformed, and finally, the tip of the vibrating piece 58 advances the sound emitting protrusion 41. get over.
When the tip of the vibrating piece 58 gets over the sound output protrusion 41, the curved and deformed vibrating piece 58 tries to restore, vibrates, and emits a sound. Therefore, the user of the present invention sensuously caps the sound. It is possible to know the end of closing the lid of C.

次に、本実施例の中栓付きボトルを使用するには、キャップCを中栓Bが装着されたボトル本体Aに対して螺脱方向に回動する。
キャップCを回動すると、まず、キャップCの音出し部材49の振動片58先端が、中栓Bのテーパ壁14の音出し突部41に当接し、さらに回動が進むと、振動片58が湾曲変形しながら進み、振動片58の先端が音出し突部41を乗り越え、湾曲変形した振動片58が復元して振動し、音が発せられる。
Next, in order to use the bottle with the inner plug of this embodiment, the cap C is rotated in the screwing direction with respect to the bottle body A to which the inner plug B is attached.
When the cap C is rotated, the tip of the vibrating piece 58 of the sound emitting member 49 of the cap C first comes into contact with the sound emitting protrusion 41 of the tapered wall 14 of the inner plug B, and when the rotation further progresses, the vibrating piece 58 Proceeds while being curved and deformed, the tip of the vibrating piece 58 gets over the sound output protrusion 41, and the curved and deformed vibrating piece 58 is restored and vibrates, and a sound is emitted.

さらに回動すると、図1(a)に示すように、キャップCの密封筒46の内周面から延びる係合腕51が回動して、その先端係合部53の第2係合面52が中栓Bの栓体20の係合突起23の第1係合面25に当接するようになり、キャップCの回転力がラチェット機構を介して栓体20に加わるようになる。
係合腕51の先端係合部53は、腕部54より厚肉に形成されているので、第2係合面52は第1係合面25に広い面積でしっかり当接係合するとともに回転力に負けない強度を有する。
Further rotation, as shown in FIG. 1A, the engaging arm 51 extending from the inner peripheral surface of the sealing cylinder 46 of the cap C rotates, and the second engaging surface 52 of the tip engaging portion 53 thereof rotates. Comes into contact with the first engaging surface 25 of the engaging projection 23 of the plug body 20 of the inner plug B, and the rotational force of the cap C is applied to the plug body 20 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 abuts and engages with the first engaging surface 25 over a wide area and rotates. Has strength that is not defeated by force.

このとき、係着部45の第2係合突部50が筒状壁21の内周面に緊密に嵌合しているので、筒状壁21を内側から補強してキャップCの回転力がラチェット機構を介して栓体20に伝わりやすくなっているとともに、ねじの回動に伴って栓体20を上方に引き上げる力を発生させる。 At this time, since the second engaging protrusion 50 of the engaging portion 45 is tightly fitted to the inner peripheral surface of the tubular wall 21, the tubular wall 21 is reinforced from the inside and the rotational force of the cap C is increased. It is easily transmitted to the plug 20 via the ratchet mechanism, and a force for pulling the plug 20 upward is generated as the screw rotates.

キャップCの回転が進むと、栓体20に加わる回転力と引き上げ力により、ついには薄肉弱化部18が破断して注出筒15内に注出口が開栓され、注出筒15の基部16から分離された栓体20は、筒状壁21に係合する係着部45によって引き上げられてキャップCとともに上昇していく。 As the rotation of the cap C progresses, the thinning weakening portion 18 finally breaks due to the rotational force and the pulling force applied to the plug body 20, and the spout is opened in the pouring cylinder 15, and the base 16 of the pouring cylinder 15 is opened. The plug body 20 separated from the cap body 20 is pulled up by the engagement portion 45 engaged with the tubular wall 21 and rises together with the cap C.

さらに、キャップCの雌ねじ55が中栓Bの雄ねじ27から螺脱して、キャップCを中栓Bから離脱させれば、キャップCとともに栓体20が除去された注出筒15の注出口からボトル本体A内の内容物を注出することができる。 Further, if the female screw 55 of the cap C is screwed off from the male screw 27 of the inner plug B and the cap C is separated from the inner plug B, the bottle is bottled from the spout of the pouring cylinder 15 from which the plug body 20 is removed together with the cap C. The contents in the main body A can be poured out.

本発明の中栓付きボトルは、開蓋時に、振動片58が振動して音が発せられるので、中栓付きボトルの利用者は、より感覚的にキャップCの開蓋の状況を知ることができる。
また、振動片58および音出し突部41は、キャップCと中栓Bに、それぞれ3個所に設けられ、ほぼ3個所が同時に音を発するので、より一層音を大きくすることができる。
In the bottle with an inner plug of the present invention, the vibrating piece 58 vibrates and emits a sound when the lid is opened, so that the user of the bottle with an inner plug can more intuitively know the situation of opening the cap C. can.
Further, the vibrating piece 58 and the sound output protrusion 41 are provided at three places each on the cap C and the inner plug B, and the sound is emitted at almost three places at the same time, so that the sound can be made even louder.

ボトル本体Aから内容物を注出した後、再度キャップCを中栓Bに螺合する際には、キャップCの密封筒46の外周が注出筒15内周に密着してボトル本体A内を密封することができる。 After pouring out the contents from the bottle body A, when the cap C is screwed into the inner plug B again, the outer circumference of the sealed cylinder 46 of the cap C comes into close contact with the inner circumference of the pouring cylinder 15 and the inside of the bottle body A. Can be sealed.

また、雄ねじ27と雌ねじ55の締結が完了する際には、再度、音出し部材49の振動片58先端が、音出し突部41に当接して振動し、音が発せられるので、中栓付きボトルの利用者は、感覚的にキャップCの閉蓋終了を知ることができる。
中栓付きボトルの利用者は、キャップCの閉蓋終了を感覚的に知ることができるので、キャップCを中栓Bに対して、無理に回動しすぎて、螺合が強くなりすぎ、開蓋するのに苦労することがない。
Further, when the fastening of the male screw 27 and the female screw 55 is completed, the tip of the vibrating piece 58 of the sound producing member 49 abuts on the sound producing protrusion 41 and vibrates, and a sound is emitted. The user of the bottle can intuitively know the end of closing the cap C.
Since the user of the bottle with the inner plug can intuitively know the end of closing the cap C, the cap C is forcibly rotated with respect to the inner plug B, and the screwing becomes too strong. You don't have to worry about opening the lid.

本実施例の中栓付きボトルは、使用した後に廃棄する際に、中栓Bが簡単な操作でボトル本体Aから分離して、分別廃棄することができる。
まず、図3および4に示す縦切断部32付近の引っ掛け部33に手指を掛けて把持部31を手前に引っ張ると、縦切断部32が破断し、把持部31は、外方に展開する。
把持凹凸部34を指で把持しながら、さらに把持部31を引っ張ると、スリット30の終端部30bに隣接して設けられた薄肉始断部36が破断し、さらに薄肉始断部36に連続する傾斜方向破断部37へと破断が進んでいく。
When the bottle with the inner plug of this embodiment is disposed of after use, the inner stopper B can be separated from the bottle body A by a simple operation and can be separately disposed of.
First, when the grip portion 31 is pulled toward by hooking a finger on the hook portion 33 near the vertical cut portion 32 shown in FIGS. 3 and 4, the vertical cut portion 32 breaks and the grip portion 31 expands outward.
When the gripping portion 31 is further pulled while gripping the gripping uneven portion 34 with a finger, the thin-walled starting portion 36 provided adjacent to the end portion 30b of the slit 30 is broken and further continuous with the thin-walled starting portion 36. The fracture progresses to the fracture portion 37 in the inclined direction.

薄肉始断部36が破断したところでは、下部係止縮径部29による下部アンダーカット部5との係合が解除されるが、上部係止縮径部28による上部アンダーカット部4との係合が持続しているので、さらに把持部31を引っ張ると、図4(a)に示すように、雄ねじ27に沿って形成された傾斜方向破断部37は、雄ねじ27の1ピッチ強の長さで破断終端部37aまで破断されていくので、上部係止縮径部28による上部アンダーカット部4との係合が解除されることになり、中栓Bは、上部係止縮径部28および下部係止縮径部29による口筒部1への拘束が解除され、把持部31を引き上げると、中栓Bをボトル本体Aから離脱させ分別廃棄することができる。 When the thin-walled starting portion 36 breaks, the engagement with the lower undercut portion 5 by the lower locking reduced diameter portion 29 is released, but the engagement with the upper undercut portion 4 by the upper locking reduced diameter portion 28 Since the alignment is maintained, when the grip portion 31 is further pulled, as shown in FIG. 4A, the inclined direction breaking portion 37 formed along the male screw 27 has a length of a little over one pitch of the male screw 27. Since the rupture ends 37a, the upper locking reduced diameter portion 28 is disengaged from the upper undercut portion 4, and the inner plug B has the upper locking reduced diameter portion 28 and the upper locking reduced diameter portion 28. When the restraint on the mouth cylinder portion 1 by the lower locking diameter reduction portion 29 is released and the grip portion 31 is pulled up, the inner plug B can be separated from the bottle body A and separately discarded.

以上のように、本実施例の中栓付きボトルは、ボトル本体の口筒部に装着される中栓の嵌合筒部の外周面にねじ部を形成することができるとともに、使用後の廃棄時に、中栓とボトル本体との分別を容易にすることができるという顕著な効果を奏する。 As described above, in the bottle with an inner stopper of this embodiment, a threaded portion can be formed on the outer peripheral surface of the fitting cylinder portion of the inner stopper attached to the mouth cylinder portion of the bottle body, and the bottle is discarded after use. At times, it has the remarkable effect of facilitating the separation of the inner plug and the bottle body.

次に、抜栓機構および音出し機構を省略し、中栓およびキャップの構造をシンプルにした第2実施例について説明する。
以下、第1実施例と同一の構成部分には同一の符号を付し、異なる構成部分のみ異なる符号を付して相違点を中心に説明する。
