Description

本発明は、ボトル本体に形成されているボトル口部に装着されるボトルキャップ、およびこのボトルキャップとボトル本体からなる飲料用ボトルに関する。   The present invention relates to a bottle cap attached to a bottle mouth portion formed in a bottle body, and a beverage bottle comprising the bottle cap and the bottle body.

従来、飲料が充填されたボトル口部を閉塞するボトルキャップとしては、内部に粉末、あるいは液状などの原料を収容する収容部を有する内筒部材の開栓操作に伴って収容部を開き、原料をボトル本体内に放出するタイプのボトルキャップおよび飲料用ボトルが提案されている。
内筒部材は外筒部材に着脱自在に螺合装着され、外筒部材はボトル口部に固定的に装着される。そして開栓操作は、内筒部材のキャップ部を外筒部材に対して開方向に捩ることでおこなわれる。 Conventionally, as a bottle cap that closes a bottle mouth portion filled with a beverage, the container portion is opened in accordance with the opening operation of the inner cylinder member that has a container portion that contains a raw material such as powder or liquid, and the raw material Bottle caps and beverage bottles of the type that release a bottle into the bottle body have been proposed.
The inner cylinder member is detachably attached to the outer cylinder member, and the outer cylinder member is fixedly attached to the bottle mouth. The opening operation is performed by twisting the cap portion of the inner cylinder member in the opening direction with respect to the outer cylinder member.

この種のボトルキャップとしては、例えば下記特許文献１、２に記載のものが知られている。
かかるボトルキャップでは、開栓されたことを確認するため、脆弱なブリッジで内筒部材（子キャップ）と連結されたバンド部を、外筒部材（親キャップ）に対して抜出不能に装着している。バンド部は内筒部材とともに外筒部材に螺合装着され、内筒部材が十分に締め込まれた状態でバンド部が外筒部材にロックされるようになっている。そして、装着された内筒部材を逆に開方向に螺進させた場合には、バンド部との距離が広がってブリッジ部が破断するため、飲料用ボトルの開栓確認（未開封確認）が可能になる。 As this kind of bottle cap, for example, those described in Patent Documents 1 and 2 below are known.
In such a bottle cap, in order to confirm that the bottle has been opened, a band portion connected to the inner cylinder member (child cap) by a fragile bridge is attached to the outer cylinder member (parent cap) so that it cannot be pulled out. ing. The band part is screwed to the outer cylinder member together with the inner cylinder member, and the band part is locked to the outer cylinder member in a state where the inner cylinder member is sufficiently tightened. And, when the attached inner cylinder member is screwed back in the opening direction, the distance from the band portion is widened and the bridge portion is broken, so that the beverage bottle opening confirmation (unopened confirmation) It becomes possible.

しかし、上記特許文献１に記載のボトルキャップでは、バンド部を外筒部材の首部に対して抜出不能に装着するための凹部と凸部をボトルの上下方向に設けていることから、バンド部の装着幅（ボトル上下方向の長さ）が大きくなることが避けられない。バンド部および外筒部材の首部には、凹部または凸部の自体の深さに加え、互いに嵌合動作をするための摺動幅をさらに上下方向に要するためである。このため、ボトルキャップの高さ寸法が大きくなり、ひいては飲料用ボトル全体が高くなって搬送性や陳列性に問題が生じる。   However, in the bottle cap described in Patent Document 1, since the concave portion and the convex portion for attaching the band portion to the neck portion of the outer cylinder member so as not to be pulled out are provided in the vertical direction of the bottle, It is inevitable that the mounting width of the bottle (length in the vertical direction of the bottle) will increase. This is because the band portion and the neck portion of the outer cylinder member require a sliding width for the fitting operation in the vertical direction in addition to the depth of the concave portion or the convex portion itself. For this reason, the height dimension of a bottle cap becomes large, and as a result, the whole bottle for drinks becomes high, and a problem arises in a conveyance property or display property.

一方、上記特許文献２に記載のボトルキャップでは、外筒部材の首部に環状の横向き凹部を設け、キャップ部とともに螺合装着されたバンド部を外筒部材にラッチ嵌合させていることから、バンド部の装着幅を抑制することができる。
しかし、かかるボトルキャップにおいては、内筒部材が締め込まれた状態におけるバンド部のラッチ爪と外筒部材のラッチ爪との位置関係によっては、キャップ部の開栓時にブリッジが破断せず、バンド部がキャップ部とともに外筒部材から脱離してしまうという問題があった。すなわち、キャップ部が巻き締められた状態で、バンド部と外筒部材のラッチ爪同士が適正にラッチ嵌合した場合は、バンド部は外筒部材より抜出不能となるため、キャップ部の開栓時にブリッジは良好に破断する。しかし、製造公差などにより内筒部材の締め込み位置が変動した場合には、バンド部と外筒部材のラッチ爪同士が適正にラッチ嵌合せず、互いに乗り上げた状態で巻き締めが終了することとなる。かかる場合、ラッチ爪は静的応力によって経時的に押し潰されて塑性変形し、以後は所望の嵌合力が得られなくなるため、開栓時にはキャップ部に追随して外筒部材より脱離して開栓確認の用をなさなくなる。 On the other hand, in the bottle cap described in Patent Document 2, an annular lateral recess is provided at the neck of the outer cylinder member, and the band part screwed together with the cap part is latch-fitted to the outer cylinder member. The mounting width of the band portion can be suppressed.
However, in such a bottle cap, depending on the positional relationship between the latch claw of the band part and the latch claw of the outer cylinder member when the inner cylinder member is tightened, the bridge does not break when the cap part is opened. There is a problem that the part is detached from the outer cylinder member together with the cap part. In other words, when the cap part is tightly wound and the latching claws of the band part and the outer cylinder member are properly latched, the band part cannot be removed from the outer cylinder member. The bridge breaks well when plugged. However, when the tightening position of the inner cylinder member fluctuates due to manufacturing tolerances etc., the latching claws of the band part and the outer cylinder member do not latch properly, and the winding tightening ends when they ride on each other Become. In such a case, the latch claw is crushed over time by the static stress and plastically deformed, and after that, the desired fitting force cannot be obtained. Stop using the plug.

本発明は上述の課題に鑑みてなされたものであり、バンド部の装着幅を抑制しつつ、キャップ部の開栓時にはブリッジ部が確実に破断して開栓確認をすることのできるボトルキャップおよび飲料用ボトルを提供するものである。   The present invention has been made in view of the above-described problems, and a bottle cap capable of reliably confirming the opening when the bridge portion is reliably broken when the cap portion is opened while suppressing the mounting width of the band portion.

Thereby, when the lower end protrusion 25 of the accommodating portion 22 is fitted into the annular recess 43, the bottom cover member 40 is attached to the accommodating portion 22, and depending on the weight of the bottom lid member 40 and the input material 200, the bottom lid member 40 does not leave the housing portion 22.

なお、環状凹部４３の内部底面には、リング状のパッキンＰ１が設置されている。収容部２２の下端突起部２５が環状凹部４３に嵌め込まれた際に、パッキンＰ１は押圧されて収容部２２の内部と外部、詳しくは収容部２２と底蓋部材４０との間のシール性が向上している。
周壁部分４４の上面には、他のリング状のパッキンＰ２が設置されている。パッキンＰ２は、外筒部材３０の下端３４と底蓋部材４０の周壁部分４４との間のシール性を向上している。したがって、収容部２２の内部に収容された投入物２００は、パッキンＰ１，Ｐ２によって二重にシールされている。 A ring-shaped packing P <b> 1 is installed on the inner bottom surface of the annular recess 43. When the lower end protruding portion 25 of the housing portion 22 is fitted into the annular recess 43, the packing P1 is pressed to provide a sealing property between the inside and the outside of the housing portion 22, more specifically between the housing portion 22 and the bottom lid member 40. It has improved.
On the upper surface of the peripheral wall portion 44, another ring-shaped packing P2 is installed. The packing P <b> 2 improves the sealing performance between the lower end 34 of the outer cylinder member 30 and the peripheral wall portion 44 of the bottom cover member 40. Therefore, the input 200 accommodated in the accommodating portion 22 is double-sealed by the packings P1 and P2.

外筒部材３０は、外筒部３２と装着部３６とを備える。外筒部３２は、無底の円筒状の部材である。この外筒部３２は、上端３３側に内筒部材２０のキャップ部２６が螺合するとともに、下端３４がボトル口部２２０内に挿入される。したがって、外筒部３２の上部には雄ネジ部３５が刻設されている。
外筒部３２の内部は上端３３から下端３４に向かって縮径するテーパー状をなし、外筒部３２の上端３３の側から遊挿された内筒部材２０の収容部２２の外周面は、下端３４の近傍において外筒部３２の内周面と摺接する。 The outer cylinder member 30 includes an outer cylinder part 32 and a mounting part 36. The outer cylinder part 32 is a bottomless cylindrical member. The outer cylinder part 32 is screwed into the cap part 26 of the inner cylinder member 20 on the upper end 33 side, and the lower end 34 is inserted into the bottle mouth part 220. Therefore, a male screw portion 35 is engraved on the upper portion of the outer cylinder portion 32.
The inside of the outer cylinder part 32 has a tapered shape that decreases in diameter from the upper end 33 toward the lower end 34, and the outer peripheral surface of the accommodating part 22 of the inner cylinder member 20 that is loosely inserted from the upper end 33 side of the outer cylinder part 32 is In the vicinity of the lower end 34, it comes into sliding contact with the inner peripheral surface of the outer cylinder portion 32.

図３に示すように、内筒部材２０のキャップ部２６が外筒部材３０の雄ネジ部３５に完全に螺着されると、収容部２２の下端２４は外筒部３２の下端３４より下方に突出する。かかる状態で収容部２２に投入物２００を投入し、底蓋部材４０を装着すると、環状凹部４３のパッキンＰ１と収容部２２の下端２４とは当接し、周壁部分４４のパッキンＰ２と外筒部３２の下端３４とは当接する。   As shown in FIG. 3, when the cap part 26 of the inner cylinder member 20 is completely screwed into the male thread part 35 of the outer cylinder member 30, the lower end 24 of the accommodating part 22 is lower than the lower end 34 of the outer cylinder part 32. Protrusively. In this state, when the input 200 is put into the housing portion 22 and the bottom cover member 40 is mounted, the packing P1 of the annular recess 43 and the lower end 24 of the housing portion 22 come into contact with each other, and the packing P2 of the peripheral wall portion 44 and the outer cylinder portion The lower end 34 of 32 is in contact.

外筒部３２には、雄ネジ部３５の下方の首部３５１の外周面に、横方向をラッチ方向とするラッチ爪（第一ラッチ爪３００、第二ラッチ爪３１０）が設けられている。ラッチ爪の下方には、装着部３６が設けられている。装着部３６と外筒部３２は二重筒構造をなし、装着部３６の内周面の中間部には雌ネジ部３７１が設けられ、下部にはラッチ部３７２が設けられている。装着部３６と外筒部３２は一体成形されている。
ボトル口部２２０には雄ネジ部２２２が刻設され、雄ネジ部２２２の下部にはフランジ部２２４が設けられている。
外筒部３２の雌ネジ部３７１をボトル口部２２０の雄ネジ部２２２に対して巻き締めることにより、外筒部材３０はボトル本体２１０に装着される。そして、雌ネジ部３７１を十分に巻き締めて、ラッチ部３７２がフランジ部２２４を超えると、両者は互いに掛合する。これにより、ボトル本体２１０に装着された外筒部材３０の巻き弛みが規制される。 The outer cylinder portion 32 is provided with latch claws (first latch claws 300 and second latch claws 310) having a lateral direction as a latch direction on an outer peripheral surface of a neck portion 351 below the male screw portion 35. A mounting portion 36 is provided below the latch claw. The mounting portion 36 and the outer cylindrical portion 32 have a double cylinder structure, and an internal thread portion 371 is provided at an intermediate portion of the inner peripheral surface of the mounting portion 36, and a latch portion 372 is provided at the lower portion. The mounting part 36 and the outer cylinder part 32 are integrally formed.
A male screw part 222 is engraved in the bottle mouth part 220, and a flange part 224 is provided in the lower part of the male screw part 222.
The outer cylinder member 30 is attached to the bottle main body 210 by winding the female screw part 371 of the outer cylinder part 32 around the male screw part 222 of the bottle mouth part 220. Then, when the female screw portion 371 is sufficiently tightened and the latch portion 372 exceeds the flange portion 224, both engage with each other. Thereby, winding slack of outer cylinder member 30 with which bottle main part 210 was equipped is controlled.

内筒部材２０、外筒部材３０および底蓋部材４０は、同じ種類のポリマーを母材とするものであり、内筒部材２０、外筒部材３０および底蓋部材４０は、ポリプロピレン系樹脂を主成分として構成されている。
また、底蓋部材４０上に設けられたパッキンＰ１，Ｐ２は、スチレン系ゴムを主成分とする。このスチレン系ゴムは、たとえば、スチレン共重合体である。 The inner cylinder member 20, the outer cylinder member 30, and the bottom cover member 40 are made of the same type of polymer as a base material, and the inner cylinder member 20, the outer cylinder member 30, and the bottom cover member 40 are mainly made of polypropylene resin. Configured as an ingredient.
The packings P1 and P2 provided on the bottom cover member 40 are mainly composed of styrene rubber. This styrene rubber is, for example, a styrene copolymer.

＜バンド部について＞
本実施形態のボトルキャップ１０は、キャップ部２６が開栓されたことを確認するためのバンド部５０を有している。バンド部５０は、キャップ部２６の下端縁２６１に対して、脆弱なブリッジ５２によって部分的に連結されている。ブリッジ５２は、バンド部５０の上面、内周面または外周面に接続されている。 <About the band>
The bottle cap 10 of the present embodiment has a band part 50 for confirming that the cap part 26 has been opened. The band part 50 is partially connected to the lower end edge 261 of the cap part 26 by a fragile bridge 52. The bridge 52 is connected to the upper surface, inner peripheral surface or outer peripheral surface of the band unit 50.

バンド部５０は、キャップ部２６を介して内筒部材２０と一体化されて外筒部材３０に螺合装着される。内筒部材２０の雌ネジ部２８は、右ネジ方向に回転することにより、外筒部材３０の雄ネジ部３５に対して閉方向に螺合する。逆に、外筒部材３０に対して内筒部材２０を左ネジ方向に旋回させることにより、キャップ部２６は開方向に回転して外筒部３２の雄ネジ部３５から脱離する。   The band part 50 is integrated with the inner cylinder member 20 via the cap part 26 and screwed to the outer cylinder member 30. The female screw portion 28 of the inner cylinder member 20 is screwed in the closing direction with the male screw portion 35 of the outer cylinder member 30 by rotating in the right screw direction. Conversely, by rotating the inner cylinder member 20 in the left screw direction relative to the outer cylinder member 30, the cap part 26 rotates in the opening direction and is detached from the male screw part 35 of the outer cylinder part 32.

図５は、図３のＶ−Ｖ断面図である。ただし、収容部２２および投入物２００は図示を省略している。
バンド部５０の内周面５４および外筒部材３０の外周面３８には、ラッチ爪がそれぞれ複数個ずつ設けられている。ラッチ爪は、外筒部材３０に対するバンド部５０の回転を、キャップ部２６の開方向に規制し、閉方向に許容する。キャップ部２６の開方向および閉方向を矢印にて図示する。 5 is a cross-sectional view taken along the line VV in FIG. However, illustration of the accommodating part 22 and the input material 200 is abbreviate | omitted.
A plurality of latch claws are provided on the inner peripheral surface 54 of the band portion 50 and the outer peripheral surface 38 of the outer cylinder member 30 respectively. The latch claw restricts the rotation of the band portion 50 relative to the outer cylinder member 30 in the opening direction of the cap portion 26 and allows it in the closing direction. The opening direction and the closing direction of the cap part 26 are illustrated by arrows.

本実施形態の場合、より具体的には、バンド部５０のラッチ爪（第一ラッチ爪５００および第二ラッチ爪５１０）は、キャップ部２６の閉方向の前方側に傾斜面５０１を有し、後方側に立面５０２を有する。
一方、外筒部材３０のラッチ爪（第一ラッチ爪３００および第二ラッチ爪３１０）は、キャップ部２６の閉方向の前方側に立面３０２を有し、後方側に傾斜面３０１を有する。
すなわち、バンド部５０および外筒部材３０のラッチ爪は、キャップ部２６の閉方向を送り方向とし、開方向をラッチ方向として形成されている。 In the case of the present embodiment, more specifically, the latch claw (the first latch claw 500 and the second latch claw 510) of the band unit 50 has an inclined surface 501 on the front side in the closing direction of the cap unit 26, An elevation surface 502 is provided on the rear side.
On the other hand, the latch claws (the first latch claws 300 and the second latch claws 310) of the outer cylinder member 30 have an upright surface 302 on the front side in the closing direction of the cap portion 26 and an inclined surface 301 on the rear side.
That is, the latching claws of the band part 50 and the outer cylinder member 30 are formed with the closing direction of the cap part 26 as the feeding direction and the opening direction as the latching direction.

よって、内筒部材２０とともに巻き締められるバンド部５０が、外筒部材３０の首部３５１に至ると、キャップ部２６とともに閉方向に回転する動作は許容され、キャップ部２６が開方向に回転する場合は、これに追随しようとするバンド部５０の回転は阻止される。
ボトルキャップ１０がボトル本体２１０に固定装着された状態から、内筒部材２０を開栓した場合、キャップ部２６は雄ネジ部３５に対して開方向に回転しつつ螺進する。一方、バンド部５０はラッチ爪同士の係合によって外筒部材３０に対する回転が規制されるため、バンド部５０とキャップ部２６との相対位置は乖離して脆弱なブリッジ５２は破断し、キャップ部２６の開栓が確認される。 Therefore, when the band part 50 wound together with the inner cylinder member 20 reaches the neck part 351 of the outer cylinder member 30, the operation of rotating in the closing direction together with the cap part 26 is permitted, and the cap part 26 rotates in the opening direction. The rotation of the band unit 50 which tries to follow this is prevented.
When the inner cylinder member 20 is opened from the state in which the bottle cap 10 is fixedly attached to the bottle main body 210, the cap portion 26 is screwed while rotating in the opening direction with respect to the male screw portion 35. On the other hand, since the rotation of the band portion 50 with respect to the outer cylinder member 30 is restricted by the engagement of the latch claws, the relative position between the band portion 50 and the cap portion 26 is deviated, and the fragile bridge 52 is broken and the cap portion is broken. 26 plugs are confirmed.

ここで、本実施形態の外筒部材３０およびバンド部５０は、一の係合位置で互いに係合する第一ラッチ爪５００、３００と、他の係合位置で互いに係合する第二ラッチ爪５１０、３１０をそれぞれ有している。   Here, the outer cylinder member 30 and the band portion 50 of the present embodiment include the first latch claws 500 and 300 that engage with each other at one engagement position, and the second latch claws that engage with each other at another engagement position. 510 and 310, respectively.

本実施形態のボトルキャップ１０は、外筒部材３０に螺合装着されたキャップ部２６が外筒部材３０に対して開方向に回転する際に、第一ラッチ爪５００、３００または第二ラッチ爪５１０、３１０のいずれかが互いに係合して、外筒部材３０に対するバンド部５０の回転を規制する。   The bottle cap 10 of the present embodiment has the first latching claws 500 and 300 or the second latching claws when the cap portion 26 screwed to the outer cylinder member 30 rotates in the opening direction with respect to the outer cylinder member 30. Either of 510 and 310 is engaged with each other to restrict the rotation of the band portion 50 relative to the outer cylinder member 30.

図５は、第一ラッチ爪５００、３００が互いに係合したラッチ状態、すなわちバンド部５０と外筒部材３０とが一の係合位置（第一の係合位置）にある状態を示している。
バンド部５０の第一ラッチ爪５００（５００ａ〜５００ｊ）は、外筒部材３０の第一ラッチ爪３００（３００ａ〜３００ｊ）と互いに係合している。
図６は、第二ラッチ爪５１０、３１０が互いに係合したラッチ状態、すなわちバンド部５０と外筒部材３０とが他の係合位置（第二の係合位置）にある状態を示している。
バンド部５０の第二ラッチ爪５１０（５１０ａ〜５１０ｄ）は、外筒部材３０の第二ラッチ爪３１０（３１０ａ〜３１０ｄ）と互いに係合している。 FIG. 5 shows a latched state in which the first latch claws 500 and 300 are engaged with each other, that is, a state in which the band portion 50 and the outer cylinder member 30 are in one engagement position (first engagement position). .
The first latch claws 500 (500a to 500j) of the band portion 50 are engaged with the first latch claws 300 (300a to 300j) of the outer cylinder member 30.
FIG. 6 shows a latched state in which the second latch claws 510 and 310 are engaged with each other, that is, a state in which the band portion 50 and the outer cylinder member 30 are in another engagement position (second engagement position). .
The second latch claws 510 (510a to 510d) of the band part 50 are engaged with the second latch claws 310 (310a to 310d) of the outer cylinder member 30.

このように、本実施形態のバンド部５０と外筒部材３０とは、複数の係合位置にて互いのラッチ爪を係合させることができる。このため、キャップ部２６の巻き締めが終了した時点でのバンド部５０と外筒部材３０との位置関係によらず、バンド部５０には開方向への回転を規制するラッチ嵌合力が与えられる。   Thus, the band part 50 and the outer cylinder member 30 of this embodiment can engage each other with latch claws at a plurality of engagement positions. For this reason, regardless of the positional relationship between the band part 50 and the outer cylinder member 30 at the time when the tightening of the cap part 26 is finished, the band part 50 is given a latch fitting force that restricts rotation in the opening direction. .

バンド部５０または外筒部材３０の一方には、第一ラッチ爪５００、３００および第二ラッチ爪５１０、３１０が等しい角度間隔で設けられている。本実施形態の場合、バンド部５０には、第一ラッチ爪５００（５００ａ〜５００ｊ）または第二ラッチ爪５１０（５１０ａ〜５１０ｄ）の一方または両方として機能する合計１６個のラッチ爪が、バンド部５０の内周面５４に亘って、互いに２２．５度の角度間隔で設けられている。ただし、１６個のラッチ爪には、第一ラッチ爪５００または第二ラッチ爪５１０として機能しないものが一部に含まれてもよい。   The first latch claws 500 and 300 and the second latch claws 510 and 310 are provided at equal angular intervals on one of the band portion 50 and the outer cylinder member 30. In the case of this embodiment, the band portion 50 includes a total of 16 latch claws that function as one or both of the first latch claws 500 (500a to 500j) and the second latch claws 510 (510a to 510d). 50 inner circumferential surfaces 54 are provided at an angular interval of 22.5 degrees. However, the 16 latch claws may include a part that does not function as the first latch claws 500 or the second latch claws 510.

バンド部５０に設けるラッチ爪（第一ラッチ爪５００、第二ラッチ爪５１０）を等間隔とすることにより、バンド部５０の成形性が良好になるとともに、バンド部５０の装着時に外筒部材３０のラッチ爪（第一ラッチ爪３００、第二ラッチ爪３１０）から受ける衝撃がバンド部５０の周方向に分散する。また、バンド部５０の１６個のラッチ爪に対して、いずれの位置でキャップ部２６の巻き締まりが終了したとしても共通の係合位置となる。   By making the latch claws (the first latch claws 500 and the second latch claws 510) provided in the band part 50 at equal intervals, the formability of the band part 50 is improved and the outer cylinder member 30 is attached when the band part 50 is attached. The impact received from the latch claws (the first latch claws 300 and the second latch claws 310) is dispersed in the circumferential direction of the band portion 50. In addition, the 16 engaging claws of the band unit 50 have a common engagement position regardless of the position at which the tightening of the cap unit 26 ends.

そして、バンド部５０または外筒部材３０の他方には、第一ラッチ爪同士が上記角度間隔の整数倍の間隔で設けられているとともに、第二ラッチ爪が第一ラッチ爪に対して上記角度間隔の非整数倍の間隔で設けられている。本実施形態の場合、外筒部材３０には、第一ラッチ爪３００（３００ａ〜３００ｊ）同士の間隔は２２．５度または４５度であり、第一ラッチ爪３００（３００ａ〜３００ｊ）と第二ラッチ爪３１０（３１０ａ〜３１０ｄ）との間隔は１１．２５度である。   The other of the band part 50 or the outer cylinder member 30 is provided with first latching claws at an interval that is an integral multiple of the angular interval, and the second latching claw is at the angle with respect to the first latching claw. It is provided at intervals that are non-integer multiples of the intervals. In the case of the present embodiment, the outer cylinder member 30 has an interval between the first latch claws 300 (300a to 300j) of 22.5 degrees or 45 degrees, and the first latch claws 300 (300a to 300j) and the second latch claws 300 (300a to 300j). The distance from the latch claw 310 (310a to 310d) is 11.25 degrees.

すなわち、外筒部材３０の第一ラッチ爪３００の配置位置は、下表１のとおりである。便宜上、第一ラッチ爪３００ａを基準として、外筒部材３０の外周面３８における開方向の角度位置を示す。   That is, the arrangement position of the first latch claw 300 of the outer cylinder member 30 is as shown in Table 1 below. For convenience, the angular position in the opening direction on the outer peripheral surface 38 of the outer cylinder member 30 is shown with the first latch claw 300a as a reference.

Figure 2010006415
Figure 2010006415

上表より、外筒部材３０の第一ラッチ爪３００ａ〜３００ｊは、バンド部５０におけるラッチ爪の形成ピッチである２２．５度の整数倍の角度間隔で互いに配置されている。   From the above table, the first latch claws 300a to 300j of the outer cylinder member 30 are arranged at an angular interval of an integral multiple of 22.5 degrees, which is the latch pawl formation pitch in the band portion 50.

つぎに、外筒部材３０の第二ラッチ爪３１０ａ〜３１０ｄの配置位置を下表２に示す。便宜上、第一ラッチ爪３００ａを基準として、外筒部材３０の外周面３８における開方向の角度位置を示す。   Next, the arrangement positions of the second latch claws 310a to 310d of the outer cylinder member 30 are shown in Table 2 below. For convenience, the angular position in the opening direction on the outer peripheral surface 38 of the outer cylinder member 30 is shown with the first latch claw 300a as a reference.

Figure 2010006415
Figure 2010006415

上表より、外筒部材３０の第二ラッチ爪３１０ａ〜３１０ｄは、第一ラッチ爪３００ａ〜３００ｊに対し、バンド部５０におけるラッチ爪の形成ピッチである２２．５度の非整数倍の角度間隔で配置されている。そして、第二ラッチ爪３１０ａ〜３１０ｄ同士は、バンド部５０におけるラッチ爪の形成ピッチである２２．５度の整数倍の角度間隔で互いに配置されている。   From the above table, the second latch pawls 310a to 310d of the outer cylinder member 30 are angularly spaced apart from the first latch pawls 300a to 300j by a non-integer multiple of 22.5 degrees which is the latch pawl formation pitch in the band portion 50. Is arranged in. The second latch claws 310a to 310d are arranged at an angular interval of an integral multiple of 22.5 degrees, which is the latch pawl formation pitch in the band portion 50.

これにより、キャップ部２６の巻き締まりの最終位置においてバンド部５０と外筒部材３０とが第一の係合位置またはその近傍となった場合には、外筒部材３０の第一ラッチ爪３００ａ〜３００ｊは、バンド部５０の第一ラッチ爪５００ａ〜５００ｊと、いずれも係合する。
そして、キャップ部２６の巻き締まりの最終位置においてバンド部５０と外筒部材３０とが第二の係合位置またはその近傍となった場合には、外筒部材３０の第一ラッチ爪３００ａ〜３００ｊは、バンド部５０の第一ラッチ爪５００ａ〜５００ｊと、いずれも係合する。 Thereby, when the band part 50 and the outer cylinder member 30 are in the first engagement position or the vicinity thereof at the final tightening position of the cap part 26, the first latching claws 300a to 300a of the outer cylinder member 30 are provided. 300j engages with the first latch claws 500a to 500j of the band unit 50.
When the band portion 50 and the outer cylinder member 30 are at or near the second engagement position at the final tightening position of the cap portion 26, the first latch claws 300a to 300j of the outer cylinder member 30 are used. Are engaged with the first latching claws 500a to 500j of the band portion 50.

本実施形態では、外筒部材３０、バンド部５０とも、第一ラッチ爪５００、３００および第二ラッチ爪５１０、３１０は、それぞれ複数個ずつ設けられている。これにより、いずれの係合位置をとった場合も、ラッチ爪同士は強固に係合してバンド部５０が外筒部材３０から脱離することを防ぐ。   In this embodiment, both the outer cylinder member 30 and the band portion 50 are provided with a plurality of first latch claws 500 and 300 and a plurality of second latch claws 510 and 310, respectively. As a result, regardless of the engagement position, the latch claws are firmly engaged to prevent the band portion 50 from being detached from the outer cylinder member 30.

なお、図６に示すように、バンド部５０のラッチ爪の一部は、第一ラッチ爪５００と第二ラッチ爪５１０を兼用している。具体的には、第一の係合位置（図５）に外筒部材３０の第一ラッチ爪３００ｃと係合する第一ラッチ爪５００ｃは、第二の係合位置（図６）においては外筒部材３０の第二ラッチ爪３１０ｂと係合する第二ラッチ爪５１０ｂとして機能する。同様に、第一ラッチ爪５００ｉと第二ラッチ爪５１０ｄは共通である。   Note that, as shown in FIG. 6, a part of the latch claw of the band unit 50 also serves as the first latch claw 500 and the second latch claw 510. Specifically, the first latch claw 500c that engages with the first latch claw 300c of the outer cylinder member 30 at the first engagement position (FIG. 5) is outside at the second engagement position (FIG. 6). It functions as a second latch claw 510b that engages with the second latch claw 310b of the cylindrical member 30. Similarly, the first latch claw 500i and the second latch claw 510d are common.

＜ラッチ爪の乗り上げについて＞
図７は、キャップ部２６（図示せず）の巻き締まり位置におけるバンド部５０と外筒部材３０の位置関係に関する他の態様を示す模式図である。図５とは、バンド部５０の角度位置が開方向に約５度前進している点で相違する。図７の状態を第三の係合位置とする。 <About the latch claw ride>
FIG. 7 is a schematic view showing another aspect regarding the positional relationship between the band part 50 and the outer cylinder member 30 at the tightening position of the cap part 26 (not shown). FIG. 5 is different from FIG. 5 in that the angular position of the band unit 50 is advanced about 5 degrees in the opening direction. Let the state of FIG. 7 be a 3rd engagement position.

第三の係合位置では、図示のように、バンド部５０の第一ラッチ爪５００（５００ａ、５００ｂ）と、外筒部材３０の第一ラッチ爪３００（３００ａ、３００ｂ）とが互いに乗り上げた状態にある。かかる状態でキャップ部２６の巻き締めが終了した場合、第一ラッチ爪５００、３００は以後も互いに乗り上げた状態で静置されることから、経時的に塑性変形して立面３０２、５０２の高さが低減する。   In the third engagement position, as shown in the figure, the first latching claws 500 (500a, 500b) of the band portion 50 and the first latching claws 300 (300a, 300b) of the outer cylinder member 30 ride on each other. It is in. When the tightening of the cap portion 26 is completed in such a state, the first latch claws 500 and 300 are left standing in a state where they are laid on each other. Is reduced.

図８は、第三の係合位置からキャップ部２６（図示せず）を開栓した状態を示す模式図である。キャップ部２６が開栓されると、ブリッジ５２でこれに接続されたバンド部５０は開方向に回転力を受けるため、第一ラッチ爪５００、３００の乗り上げは解消される。
ここで、本実施形態のボトルキャップ１０では、第二ラッチ爪５１０（５１０ａ）および３１０（３１０ａ）に関しては乗り上げが生じていないことから、図６と同様の第二の係合位置において、バンド部５０の回転は規制される。
また、図７に示す第三の係合位置において第一ラッチ爪３００ｃによって押し潰されていた第一ラッチ爪５００ｃは、図８に示すように第二ラッチ爪３１０ｂと係合する第二ラッチ爪５１０ｂとして機能し、バンド部５０の開方向への回転を規制する。 FIG. 8 is a schematic view showing a state where the cap portion 26 (not shown) is opened from the third engagement position. When the cap portion 26 is opened, the band portion 50 connected thereto by the bridge 52 receives a rotational force in the opening direction, so that the riding of the first latch claws 500 and 300 is eliminated.
Here, in the bottle cap 10 of the present embodiment, the second latch claws 510 (510a) and 310 (310a) do not ride up, so in the second engagement position similar to FIG. The rotation of 50 is restricted.
Further, the first latch claw 500c crushed by the first latch claw 300c in the third engagement position shown in FIG. 7 is the second latch claw engaged with the second latch claw 310b as shown in FIG. It functions as 510b and regulates rotation of the band unit 50 in the opening direction.

本実施形態のボトルキャップ１０は、図５に示すように、第一の係合位置にて、互いに係合した隣接する第一ラッチ爪５００ａと５００ｂ、および第一ラッチ爪３００ａと３００ｂの間には、バンド部５０の第二ラッチ爪５１０ａと外筒部材の第二ラッチ爪３１０ａとが、開方向にこの順に並んで設けられている。
また、図６、８に示すように、第二の係合位置にて、互いに係合した隣接する第二ラッチ爪５１０ａと５１０ｂ、および３１０ａと３１０ｂの間には、バンド部５０の第一ラッチ爪５００ｂと外筒部材３０の第一ラッチ爪３００ｂ、３００ｃとが、開方向にこの順に並んで設けられている。 As shown in FIG. 5, the bottle cap 10 of the present embodiment has a first engagement position between adjacent first latch claws 500a and 500b and first latch claws 300a and 300b. The second latch claw 510a of the band portion 50 and the second latch claw 310a of the outer cylinder member are provided in this order in the opening direction.
In addition, as shown in FIGS. 6 and 8, the first latch of the band portion 50 is disposed between the adjacent second latch claws 510a and 510b and 310a and 310b that are engaged with each other in the second engagement position. The claw 500b and the first latching claw 300b, 300c of the outer cylinder member 30 are provided in this order in the opening direction.

これにより、キャップ部２６の巻き締めの終了時に第一ラッチ爪５００と３００、または第二ラッチ爪５１０と３１０とが互いに干渉してラッチ爪が経時的に損滅したとしても、他方のラッチ爪にはかかる干渉が生じないことから、バンド部５０の開方向への規制力が失われることはない。   Thus, even if the first latching claws 500 and 300 or the second latching claws 510 and 310 interfere with each other at the end of the tightening of the cap portion 26 and the latching claws are destroyed over time, the other latching claws Since such interference does not occur, the regulating force in the opening direction of the band portion 50 is not lost.

本実施形態のキャップ部２６は、第一の係合位置から第二の係合位置まで回転した際の螺進長さが、第二ラッチ爪５１０、３１０の爪幅よりも小さい。
また、キャップ部２６は、第二の係合位置から第一の係合位置まで回転した際の螺進長さが、第一ラッチ爪５００、３００の爪幅よりも小さい。
ここで、キャップ部２６の螺進長さとは、所定角度だけキャップ部２６が回転した場合の軸方向の変位量をいう。また、ラッチ爪の爪幅とは、ボトルキャップ１０の高さ方向に関する当該ラッチ爪の寸法をいう。
なお、第一ラッチ爪５００と３００、または第二ラッチ爪５１０と３１０の爪幅が互いに相違する場合、上記螺進長さは、いずれか大きい方の爪幅よりも小さければ足りる。 The cap portion 26 of the present embodiment has a screwing length when rotated from the first engagement position to the second engagement position, which is smaller than the claw width of the second latch claws 510 and 310.
The cap portion 26 has a screwing length that is smaller than the claw widths of the first latch claws 500 and 300 when rotated from the second engagement position to the first engagement position.
Here, the screwing length of the cap portion 26 refers to the amount of displacement in the axial direction when the cap portion 26 rotates by a predetermined angle. The claw width of the latch claw refers to the dimension of the latch claw in the height direction of the bottle cap 10.
When the claw widths of the first latch claws 500 and 300 or the second latch claws 510 and 310 are different from each other, it is sufficient that the screwing length is smaller than the larger claw width.

これにより、内筒部材２０の巻き締め時に、第一または第二の係合位置よりずれて、ラッチ爪同士が互いに干渉して乗り上げた状態が形成されたとしても、内筒部材２０の開栓時にバンド部５０が外筒部材３０から抜けてしまうことなく、隣接する他のラッチ爪による係合力によってバンド部５０の開方向への回転が規制される。   As a result, even when the inner cylinder member 20 is tightened, even if a state in which the latch claws interfere with each other and are moved up from the first or second engagement position is formed, the inner cylinder member 20 is opened. Sometimes, the band part 50 does not come out of the outer cylinder member 30, and the rotation of the band part 50 in the opening direction is restricted by the engaging force of another adjacent latch claw.

＜係合部について＞
図９は、内筒部材２０が外筒部材３０に螺合装着した状態を示す部分拡大図である。
本実施形態のキャップ部２６の下端縁２６１とバンド部５０の上縁５６には、キャップ部２６が閉方向に回転することで互いに係合する係合部６０がそれぞれ設けられている。 <About engaging part>
FIG. 9 is a partially enlarged view showing a state in which the inner cylinder member 20 is screwed to the outer cylinder member 30.
In the present embodiment, the lower end edge 261 of the cap portion 26 and the upper edge 56 of the band portion 50 are respectively provided with engaging portions 60 that engage with each other when the cap portion 26 rotates in the closing direction.

キャップ部２６の下端縁２６１またはバンド部５０の上縁５６には、係合部６０として、係合凹部６２または係合凸部７２が設けられている。   On the lower end edge 261 of the cap portion 26 or the upper edge 56 of the band portion 50, an engagement concave portion 62 or an engagement convex portion 72 is provided as the engagement portion 60.

本実施形態の場合、キャップ部２６の下端縁２６１には係合凹部６２が彫り込み形成されている。また、バンド部５０の上縁５６には、係合凸部７２が突出して一体に形成されている。   In the case of this embodiment, an engaging recess 62 is engraved on the lower end edge 261 of the cap portion 26. Further, an engaging convex portion 72 protrudes and is integrally formed on the upper edge 56 of the band portion 50.

係合凸部７２は、キャップ部２６の閉方向（図中左方向）の前端側に傾斜面７３を有し、後端側に立面７４を有している。
係合凸部７２と凹凸嵌合する係合凹部６２も同様に、キャップ部２６の閉方向の前端側に傾斜面６３を有し、後端側には立面である係合面６４を有している。 The engaging convex portion 72 has an inclined surface 73 on the front end side in the closing direction (left direction in the figure) of the cap portion 26 and has an upright surface 74 on the rear end side.
Similarly, the engaging concave portion 62 which is engaged with the engaging convex portion 72 has an inclined surface 63 on the front end side in the closing direction of the cap portion 26 and an engaging surface 64 which is an upright surface on the rear end side. is doing.

係合凹部６２は、係合凸部７２と係合する係合面６４が、キャップ部２６の下端縁２６１またはバンド部５０の上縁５６より突出して形成されている。   The engaging concave portion 62 is formed with an engaging surface 64 that engages with the engaging convex portion 72 protruding from the lower edge 261 of the cap portion 26 or the upper edge 56 of the band portion 50.

また、キャップ部２６の下端縁２６１またはバンド部５０の上縁５６は、係合凹部６２の係合面６４を含む突起部６６を有している。   Further, the lower edge 261 of the cap part 26 or the upper edge 56 of the band part 50 has a protrusion 66 including the engagement surface 64 of the engagement recess 62.

本実施形態の場合、係合面６４およびこれを含む突起部６６は、キャップ部２６の下端縁２６１より下方に突出して形成されている。
かかる構成により、キャップ部２６を閉方向に回転させた際に、係合凹部６２の係合面６４が係合凸部７２の立面７４を押し込むこととなる。このため、脆弱なブリッジ５２を破断してしまうことなくバンド部５０を外筒部材３０に装着することができる。
特に、下端縁２６１より突出する突起部６６をキャップ部２６に設けることにより、係合凹部６２と係合凸部７２とを深く係合させることができ、キャップ部２６の螺合装着時に係合面６４が係合凸部７２を乗り越えてしまうことを防止している。 In the case of the present embodiment, the engagement surface 64 and the protrusion 66 including the engagement surface 64 are formed to protrude downward from the lower end edge 261 of the cap portion 26.
With this configuration, when the cap portion 26 is rotated in the closing direction, the engaging surface 64 of the engaging concave portion 62 pushes the vertical surface 74 of the engaging convex portion 72. For this reason, the band part 50 can be attached to the outer cylinder member 30 without breaking the fragile bridge 52.
In particular, by providing the cap portion 26 with a projection 66 protruding from the lower edge 261, the engagement recess 62 and the engagement projection 72 can be deeply engaged, and engaged when the cap portion 26 is screwed. The surface 64 is prevented from getting over the engaging convex portion 72.

キャップ部２６の下端縁２６１またはバンド部５０の上縁５６の少なくとも一方は、突起部６６よりも開方向に離間した位置にスペーサ部５８をさらに備えている。本実施形態では、バンド部５０の上縁５６にスペーサ部５８が設けられている。
スペーサ部５８は、キャップ部２６の下端縁２６１とバンド部５０の上縁５６とが接近しすぎることを防止する。すなわち、キャップ部２６を外筒部材３０に螺合装着する際に、下方に螺進するキャップ部２６はバンド部５０を下方に押圧するところ、スペーサ部５８が無い場合は、キャップ部２６とバンド部５０とは下端縁２６１と上縁５６とを当接させながら外筒部材３０の周囲を回転することとなる。この場合、ブリッジ５２は下端縁２６１と上縁５６に押し潰されながら剪断されるため、キャップ部２６の螺合時に破断しやすくなる。
これに対し、本実施形態のようにスペーサ部５８を設けることで、キャップ部２６の螺合時にバンド部５０との距離が所定以上に維持されるため、ブリッジ５２の剪断が防止される。
なお、本実施形態のように係合面６４を下端縁２６１から突出させた突起部６６は、前述の押し込み力の向上に加え、スペーサとしての機能を果たす。 At least one of the lower end edge 261 of the cap part 26 or the upper edge 56 of the band part 50 further includes a spacer part 58 at a position separated from the protrusion part 66 in the opening direction. In the present embodiment, a spacer portion 58 is provided on the upper edge 56 of the band portion 50.
The spacer part 58 prevents the lower end edge 261 of the cap part 26 and the upper edge 56 of the band part 50 from being too close to each other. That is, when the cap portion 26 is screwed and attached to the outer cylinder member 30, the cap portion 26 that is screwed downward presses the band portion 50 downward. When the spacer portion 58 is not provided, the cap portion 26 and the band The portion 50 rotates around the outer cylindrical member 30 while the lower edge 261 and the upper edge 56 are brought into contact with each other. In this case, since the bridge 52 is sheared while being crushed by the lower edge 261 and the upper edge 56, the bridge 52 is easily broken when the cap portion 26 is screwed.
On the other hand, by providing the spacer portion 58 as in the present embodiment, the distance from the band portion 50 is maintained at a predetermined distance or more when the cap portion 26 is screwed, so that shearing of the bridge 52 is prevented.
In addition, the projection part 66 which made the engaging surface 64 protrude from the lower end edge 261 like this embodiment fulfill | performs the function as a spacer in addition to the improvement of the above-mentioned pushing force.

なお、本実施形態ではキャップ部２６の下端縁２６１に係合凹部６２を形成し、バンド部５０の上縁５６に係合凸部７２を形成する場合を例に説明したが、逆にキャップ部２６の下端縁２６１より下方に突出する係合凸部を形成し、バンド部５０の上縁５６に係合凹部を形成してもよい。
また、係合部６０は、本実施形態のように凹部と凸部との組み合わせによらず、凸部同士の係合によるものでもよい。 In the present embodiment, the case where the engagement concave portion 62 is formed on the lower edge 261 of the cap portion 26 and the engagement convex portion 72 is formed on the upper edge 56 of the band portion 50 has been described as an example. 26 may be formed on the upper edge 56 of the band portion 50, and an engaging recess may be formed on the upper edge 56 of the band portion 50.
Further, the engaging portion 60 may be based on the engagement of the convex portions, not the combination of the concave portions and the convex portions as in the present embodiment.

収容部２２に粉茶などの投入物２００が投入されて底蓋部材４０で密閉されたボトルキャップ１０は、図１および図３に示すように、清水などの液体が収容されたボトル本体２１０のボトル口部２２０に装着されることで、出荷される飲料用ボトル１００（図１を参照）が完成する。   As shown in FIGS. 1 and 3, the bottle cap 10 in which the input material 200 such as powdered tea is charged in the storage portion 22 and sealed with the bottom lid member 40 is provided in the bottle main body 210 in which a liquid such as fresh water is stored. By mounting on the bottle mouth part 220, the beverage bottle 100 (see FIG. 1) to be shipped is completed.

飲料用ボトル１００は、図４に示すように、一般消費者がキャップ部２６を開栓して底蓋部材４０を収容部２２より脱離することにより、収容部２２に収容されていた投入物２００とボトル本体２１０内部の液体とを混合して飲用することができる。   As shown in FIG. 4, the beverage bottle 100 has an input that is stored in the storage portion 22 by a general consumer opening the cap portion 26 and detaching the bottom lid member 40 from the storage portion 22. 200 and the liquid in the bottle main body 210 can be mixed and drunk.

キャップ部２６を開方向に回転させると、キャップ部２６は外筒部材３０に対して上方に螺進する。底蓋部材４０の周壁部分４４は外筒部材３０の下端３４に係止されているため、一定長さだけキャップ部２６を螺進させると、底蓋部材４０は収容部２２から脱落する。このため、収容部２２に収容されていた投入物２００がボトル本体２１０に投入される。   When the cap part 26 is rotated in the opening direction, the cap part 26 is screwed upward with respect to the outer cylinder member 30. Since the peripheral wall portion 44 of the bottom cover member 40 is locked to the lower end 34 of the outer cylinder member 30, when the cap portion 26 is screwed by a predetermined length, the bottom cover member 40 is dropped from the housing portion 22. For this reason, the input 200 stored in the storage unit 22 is input into the bottle main body 210.

このとき、バンド部５０は外筒部材３０に対してラッチ嵌合して開方向への回転が規制されているため、キャップ部２６の螺進に追随せず、ブリッジ５２は破断し、開栓が確認される。   At this time, since the band portion 50 is latched to the outer cylinder member 30 and the rotation in the opening direction is restricted, the cap portion 26 does not follow the screwing and the bridge 52 is broken and the plug is opened. Is confirmed.
