本考案は、球体を保持したキャップをラムネ壜の壜口部に打栓するキャップ構 造に関するものである。 The present invention relates to a cap structure in which a cap holding a sphere is inserted into a bottle mouth of a Ramune bottle.
【0002】[0002]
従来、ラムネ壜の壜口部をガラスの球体を介して封止する構造として、ラムネ 壜の製造工程において、壜内にガラスの球体を入れ、壜口部を再加熱して細径化 し、壜口内周溝に装着したパッキン部材と球体とで内部のガス圧を封止する構造 、また、実開昭62−171444号公報の第4図に示すように、壜口部に係合 させたキャップ部材でパッキン部材を固定し、ガラスの球体を内部のガス圧でパ ッキン部材に押圧させて封止する構造等が採用されて来た。 これらの封止構造を採用した場合には、ラムネ壜内に液を充填後、ラムネ壜を 逆様にして球体を封止位置に位置させるか、ラムネ壜を逆様にした状態でラムネ 壜に液を充填させるかしなければないないため、充填工程が複雑化する。 Conventionally, as a structure that seals the bottle mouth of a Ramune bottle with a glass sphere, in the manufacturing process of a Ramune bottle, put the glass sphere inside the bottle and reheat the bottle mouth to reduce the diameter. A structure in which the internal gas pressure is sealed by a packing member mounted in the inner circumferential groove of the bottle and a sphere, and as shown in FIG. 4 of Japanese Utility Model Laid-Open No. 62-171444, it is engaged with the bottle opening. A structure in which a packing member is fixed with a cap member and a glass sphere is pressed against the packing member by an internal gas pressure to seal the glass sphere has been adopted. When these sealing structures are adopted, after filling the liquid in the Ramune bottle, turn the Ramune bottle upside down to position the sphere at the sealing position, or put the Ramune bottle upside down and place it in the Ramune bottle. Since the liquid must be filled, the filling process becomes complicated.
【0003】 そこで、予めガラスの球体をキャップに保持させ、ラムネ壜に液を充填後に壜 口部にキャップを打栓するようにしたラムネ壜のキャップ構造が提案されている 。例えば、前記実開昭62−171444号公報には、ラムネ壜の壜口部の外周 面に係合されるキャップ本体(注出口部材)と、このキャップ本体に内嵌保持さ れ壜口部に内嵌されるパッキン部材と、このパッキン部材の下端から一体的に延 び球体を保持するスカート部であって4つのスリットにより周方向に4分割され たスカート部とを備え、スカート部内に保持したガラスの球体をパッキン部材の 筒部の下端内周部に当接させて封止したラムネ壜のキャップ構造が記載されてい る。Therefore, there has been proposed a Ramune bottle cap structure in which a glass sphere is held in advance in a cap, and a bottle mouth is capped with a liquid after filling the Ramune bottle with liquid. For example, in Japanese Utility Model Laid-Open No. 62-171444, a cap body (spout member) that is engaged with the outer peripheral surface of the bottle mouth portion of a Ramune bottle, and a cap body that is internally fitted and held by the cap body is provided. The packing member to be fitted inside and the skirt part that integrally extends from the lower end of the packing member and holds the sphere, which is divided into four in the circumferential direction by four slits, are held in the skirt part. There is described a Ramune bottle cap structure in which a glass sphere is brought into contact with the inner peripheral portion of the lower end of the cylindrical portion of the packing member and sealed.
【0004】 また、実開平2−8742号公報には、ラムネ壜の壜口部の外周面に係合され る硬質樹脂製のキャップ本体と、このキャップ本体に一体的に内嵌保持され環状 部において壜口部に内嵌される軟質樹脂製の内筒と、この内筒の筒状の球体保持 部に保持されるガラスの球体とを備え、球体を強力に保持する為に、内筒の球体 保持部の下側に厚肉状の突起を一体形成し、この突起の内面部に複数のガス抜き 溝を形成したラムネ壜のキャップ構造が提案されている。Further, in Japanese Utility Model Laid-Open No. 2-8742, a hard resin cap main body that is engaged with the outer peripheral surface of the bottle mouth portion of the Ramune bottle, and an annular portion integrally fitted and held in the cap main body. In this case, an inner cylinder made of a soft resin to be fitted in the bottle mouth portion and a glass sphere held in the cylindrical sphere holding portion of this inner cylinder are provided, and in order to strongly hold the sphere, A ramune bottle cap structure has been proposed in which a thick-walled projection is integrally formed on the lower side of the sphere holding portion, and a plurality of gas vent grooves are formed on the inner surface of the projection.
【0005】[0005]
前記ガラスの球体の真球度はかなり低いことから、従来のラムネ壜のキャップ 構造ではガス密性を確保するのが難しいという問題がある。 即ち、前者の公報のキャップ構造において、封止性能を高める為にキャップ部 材を軟質樹脂製にすると、パッキン部材のスカート部の剛性が低下するので、結 局封止性能を確保するのが困難になる。一方、キャップ部材を硬質樹脂製にする と、球体の真球度が低いために筒部材と球体間を完全には封止できず、壜内部か ら炭酸ガスが徐々にリークして欠陥商品になってしまう。 Since the sphericity of the glass sphere is considerably low, there is a problem that it is difficult to secure gas tightness with the conventional Ramune bottle cap structure. That is, in the cap structure of the former publication, if the cap member is made of a soft resin in order to improve the sealing performance, the rigidity of the skirt portion of the packing member decreases, so it is difficult to secure the final sealing performance. become. On the other hand, if the cap member is made of hard resin, the sphericalness of the sphere is low, so the space between the cylinder member and the sphere cannot be completely sealed, and the carbon dioxide gas gradually leaks from inside the bottle, resulting in a defective product. turn into.
【0006】 前記後者の公報のキャップ構造においては、キャップ本体が硬質樹脂製、内筒 が軟質樹脂製で、キャップ本体の成形後にこれと一体的に内筒を成形するため、 成形工程が複雑化する。また、壜口部の天面に環状の凹溝を形成するためラムネ 壜の壜口部を特殊な構造にする必要がある。 特に、球体を封止するゴム製のパッキン部材を設けずに、内筒の球体保持部に 球体の最大径部を弾性的に嵌合させてガス密に封止する構造であるが、球体の真 球度はかなり低いため、ガス密に封止する封止性能を確保するのが難しい。In the cap structure of the latter publication, the cap body is made of a hard resin and the inner cylinder is made of a soft resin, and the inner cylinder is molded integrally with the cap body after molding, which complicates the molding process. To do. In addition, since the annular groove is formed on the top surface of the bottle mouth, the bottle mouth of the Ramune bottle needs to have a special structure. In particular, the rubber packing member for sealing the sphere is not provided, and the maximum diameter portion of the sphere is elastically fitted to the sphere holding portion of the inner cylinder to seal the gas tightly. Since the sphericity is quite low, it is difficult to secure the sealing performance for gas-tight sealing.
【0007】 また、内筒の上端の開口は球体よも小径であるため、球体を内筒の球体保持部 に嵌合させる際に突起側の開口から突起を乗り越えて球体保持部内へ装着しなけ ればならないため、その球体装着の作業が容易でない。しかも、球体保持部が厚 肉の筒状に形成され、その下端部に厚肉の突起が形成されているため、内筒の樹 脂材料が多く必要でその材料コスト面で不利である。Further, since the opening at the upper end of the inner cylinder has a smaller diameter than that of the sphere, when fitting the sphere into the sphere holding portion of the inner cylinder, it is necessary to climb over the projection from the opening on the projection side and mount it in the sphere holding portion. Therefore, it is not easy to attach the sphere. Moreover, since the sphere holding portion is formed in a thick-walled cylindrical shape and the thick-walled projection is formed at the lower end portion, a large amount of resin material for the inner cylinder is required, which is disadvantageous in terms of material cost.
【0008】 本考案の目的は、ラムネ壜のキャップ構造において、ガス密に封止する封止性 能を高めること、球体を簡単に装着可能にすること、ハンドリング中の衝撃等で 球体が外れるのを防止すること、材料コストを低減すること、再使用を防止可能 にすること、等である。The object of the present invention is to improve the sealing performance of gas-tight sealing in a Ramune bottle cap structure, to make it easy to mount a sphere, and to prevent the sphere from coming off due to impact during handling, etc. Prevention, reduction of material cost, prevention of reuse, etc.

請求項1のラムネ壜のキャップ構造は、球体を保持したキャップをラムネ壜の 壜口部に打栓するキャップ構造において、前記キャップは、壜口部の外周面に係 合される外筒部を有する硬質合成樹脂製のキャップ本体と、キャップ本体に内嵌 保持される硬質合成樹脂製のホルダーと、ホルダーに保持される球体と、球体の 上半部の途中部をガス密状に受け止めるようにホルダーとキャップ本体とに挟持 されたゴム製の環状のパッキン部材とを備え、前記ホルダーは、壜口部に圧縮状 かつガス密状に内嵌されるとともに球体の最大径部の外面を保持する環状部と、 壜口部の天面とキャップ本体のフランジ押え部間にガス密状に挟持されるフラン ジ部と、環状部の下端に連なり球体の下半部を保持する球体保持部とを一体形成 してなり、前記球体保持部は、球体の下端を受け止める連結部と、この連結部か ら延び球体の下半部の表面に沿って湾曲し環状部の下端に連なる可撓性の複数の 保持片とを備え、保持片同士間に開口部を形成するとともに、連結部に球体を壜 内方へ打撃したときに破断して球体の落下を許す破断部を形成したものである。 The cap structure for a Ramune bottle according to claim 1, wherein the cap holding a spherical body is plugged into the bottle mouth portion of the Ramune bottle, wherein the cap has an outer cylindrical portion that is engaged with an outer peripheral surface of the bottle mouth portion. It has a cap body made of hard synthetic resin, a holder made of hard synthetic resin that is internally fitted and held in the cap body, a sphere held by the holder, and a gas-tight portion in the middle of the upper half of the sphere. An annular packing member made of rubber sandwiched between the holder and the cap body is provided, and the holder is fitted in the bottle mouth in a compressed and gas-tight manner and holds the outer surface of the maximum diameter portion of the sphere. An annular part, a flange part that is sandwiched in a gas-tight manner between the top surface of the bottle part and the flange retainer part of the cap body, and a sphere holding part that connects to the lower end of the annular part and holds the lower half of the sphere. Integrally formed, The body holding portion includes a connecting portion that receives the lower end of the sphere, and a plurality of flexible holding pieces that extend from the connecting portion and curve along the surface of the lower half of the sphere and that are connected to the lower end of the annular portion. An opening is formed between the holding pieces, and a rupture portion is formed at the connecting portion so that the sphere ruptures when hitting the bottle inward and allows the sphere to fall.
【0010】 ラムネ壜に液を充填した状態において、壜内のガス圧がホルダーに作用し、ま た、ホルダーの保持片同士間の開口部を介してガス圧が球体に作用する。しかし 、キャップ本体の外筒部がラムネ壜の壜口部の外周面に係合され、ホルダーとパ ッキン部材とはキャップ本体で支持されているので壜口部から外れることはない 。 ホルダーの環状部が壜口部に圧縮状にガス密状に内嵌され、また、ホルダー のフランジ部が壜口部の天面とキャップ本体のフランジ押え部間にガス密状に挟 持されているため、ホルダーと壜口部間からガスがリークすることはない。 ゴム製の環状のパッキン部材は、球体の上半部の途中部をガス密状に受け止め るようにホルダーとキャップ本体とに挟持され、球体にガス圧が作用するため、 ホルダー及びキャップ本体と球体との間からガスがリークすることはない。In the state where the Ramune bottle is filled with the liquid, the gas pressure in the bottle acts on the holder, and the gas pressure acts on the sphere through the opening between the holding pieces of the holder. However, the outer cylinder portion of the cap body is engaged with the outer peripheral surface of the bottle mouth portion of the Ramune bottle, and the holder and the packing member are supported by the cap body, so that they cannot come off from the bottle mouth portion. The annular part of the holder is compressed and gas-tightly fitted in the bottle mouth, and the flange part of the holder is gas-tightly sandwiched between the top face of the bottle mouth and the flange retainer part of the cap body. Gas does not leak from the holder to the bottle. The rubber ring-shaped packing member is sandwiched between the holder and the cap body so as to receive the middle of the upper half of the sphere in a gas-tight manner, and the gas pressure acts on the sphere. Gas does not leak from between.
【0011】 ホルダーは、球体の下半部を保持する球体保持部を備え、この球体保持部は、 球体の下端を受け止める連結部と、この連結部から延び球体の下半部の表面に沿 って湾曲し環状部の下端に連なる可撓性の複数の保持片とを備え、連結部と可撓 性の複数の保持片とで球体の下半部を確実に保持できるので、ハンドリング中に 衝撃等が作用しても球体が外れることはない。 ホルダーの保持片同士間に開口部を形成してあるので、球体に確実にガス圧を 作用させることができる。また、ホルダーの上端開口を球体よりも大きく形成す るから、ホルダーに球体を上方から簡単に装着することができる。The holder comprises a sphere holding portion for holding the lower half of the sphere, the sphere holding portion extending from the connecting portion for receiving the lower end of the sphere and extending along the surface of the lower half of the sphere. It is equipped with a plurality of flexible holding pieces that are curved and connected to the lower end of the annular portion, and the lower half of the sphere can be reliably held by the connecting portion and a plurality of flexible holding pieces, so that there is no impact during handling. The sphere does not come off even when the above acts. Since the opening is formed between the holding pieces of the holder, the gas pressure can be surely applied to the sphere. Further, since the upper end opening of the holder is formed larger than the sphere, the sphere can be easily attached to the holder from above.
【0012】 ホルダーの連結部に、球体を壜内方へ打撃したときに破断して球体の落下を許 す破断部を形成したので、また、複数の保持片が可撓性のものであるので、前記 打撃を介して球体を確実に落下させることができ、ラムネを飲む際には保持片同 士間の開口部を介して液が壜口側へ流れる。また、ホルダーは、環状部とフラン ジ部と球体保持部とを備え、球体保持部は連結部と複数の可撓性の保持片と備え た構造であるので、ホルダーを少量の材料を構成でき、その材料コストを低減で きる。キャップ構造の使用後は、破断部が破断しているため、使用済みのキャッ プ構造を再使用するのを確実に防止できる。Since the rupture portion that breaks when the sphere is hit inwardly of the bottle and allows the sphere to fall is formed in the connecting portion of the holder, the plurality of holding pieces are flexible. The sphere can be surely dropped through the striking, and when drinking ramune, the liquid flows to the bottle mouth side through the opening between the holding pieces. Further, since the holder has an annular portion, a flange portion and a sphere holding portion, and the sphere holding portion has a structure including a connecting portion and a plurality of flexible holding pieces, the holder can be made of a small amount of material. , The material cost can be reduced. After the cap structure is used, the broken part is broken, so it is possible to reliably prevent the reuse of the used cap structure.

The annular portion 21 of the holder 20 is fitted into the bottle mouth portion 3 in a compressed and gas-tight manner, the flange portion 22 is sandwiched between the top surface of the bottle mouth portion 3 and the flange pressing portion 14b, and the packing member 40 is ring-shaped. It is sandwiched between the part 21 and the packing pressing part 13a, and the packing member 40 receives the middle part of the upper half of the sphere 30 in a gas-tight manner and seals it, and the gas pressure in the bottle passes through the opening 27. It acts on the sphere 30.
【0023】 それ故、ホルダー20とパッキン部材40とはキャップ本体10により壜口部 3に固定されて外れることはない。ホルダー20にはガス圧が作用し、球体30 にもガス圧が作用するが、ホルダー20と壜口部3の間は、環状部21とフラン ジ部22とでガス密状に完全に封止され、また、ホルダー20及びキャップ本体 10と球体30の表面との間はパッキン部材40によりガス密状に完全に封止さ れる。Therefore, the holder 20 and the packing member 40 are fixed to the bottle mouth portion 3 by the cap body 10 and never come off. The gas pressure acts on the holder 20, and the gas pressure also acts on the sphere 30, but the annular portion 21 and the flange portion 22 completely seal the gap between the holder 20 and the bottle portion 3 in a gas-tight manner. Further, the space between the holder 20, the cap body 10 and the surface of the spherical body 30 is completely sealed in a gas-tight manner by the packing member 40.
【0024】 更に、開栓しない場合には、開栓具本体4は補助リング5により位置規制され て図1、図3に示した位置よりも下方へ移動しないため、開栓具本体4に外力が 作用しても開栓されることはない。開栓する場合には、開栓具本体4と補助リン グ5とを壜口部3から外し、開栓具本体4から補助リング5を外してから開栓具 本体4の筒部4bを壜口部3に挿入して筒部4bの下端を球体30に当接させ、 天板部4aを下方へ打撃し、筒部4bで球体30を下方へ打撃して、破断部を破 断させて球体30を落下させる。Further, when the cap is not opened, the position of the cap opening main body 4 is regulated by the auxiliary ring 5 and does not move below the position shown in FIGS. It will not be opened even if is activated. When opening the cap, the cap body 4 and the auxiliary ring 5 are removed from the bottle opening 3, the auxiliary ring 5 is removed from the cap opening body 4, and then the tubular portion 4b of the cap opening body 4 is bottled. Insert it into the mouth portion 3 and bring the lower end of the tubular portion 4b into contact with the spherical body 30, strike the top plate portion 4a downward, strike the spherical body 30 downward with the tubular portion 4b, and break the fractured portion. The sphere 30 is dropped.
【0025】 ホルダー20に、環状部21とフランジ部22と球体保持部24とを形成し、 球体保持部24に連結部25と3つ以上の保持片26を形成したので、球体30 の下半部を連結部25と保持片26とで確実に保持でき、ハンドリング中の衝撃 等で球体30が勝手に外れることもない。また、連結部25と保持片26とは薄 く保持片26の幅も小さいため、ホルダー20の所要合成樹脂材料が少なく、そ の合成樹脂材料コストを低減できる。Since the holder 20 is formed with the annular portion 21, the flange portion 22, and the sphere holding portion 24, and the sphere holding portion 24 is formed with the connecting portion 25 and three or more holding pieces 26, the lower half of the sphere 30 is formed. The portion can be securely held by the connecting portion 25 and the holding piece 26, and the sphere 30 does not come off by the impact during handling. Further, since the connecting portion 25 and the holding piece 26 are thin and the width of the holding piece 26 is small, the synthetic resin material required for the holder 20 is small and the cost of the synthetic resin material can be reduced.
【0026】 連結部25に形成した破断部の破断を介して球体30を壜内へ確実に落下させ ることができる。また、ラムネを飲む際には、保持片26により球体30の復帰 が阻止されるため、ラムネ壜に球体30の復帰阻止用の1対の凹部を形成する必 要もないし、また、ラムネを飲む際には、連結部25の破断部を破断させるので 、使用済みのキャップ1を再使用するのを確実に防止できる。The sphere 30 can be surely dropped into the bottle through the breakage of the breakage portion formed in the connecting portion 25. In addition, when the ramune is drunk, the holding piece 26 prevents the sphere 30 from returning, so it is not necessary to form a pair of recesses for preventing the sphere 30 from returning in the ramune bottle, and the ramune is drunk. At this time, the breaking portion of the connecting portion 25 is broken, so that it is possible to reliably prevent reuse of the used cap 1.
【0027】 前記実施形態を部分的に変更する例について説明すると、キャップ本体10の 内筒部13と中間筒部14とを筒状ではなく中実状に形成してもよく、また、ホ ルダー20の球体保持部24の保持片26は両辺が平行な帯状でなくとも細長の 台形状(上側が広幅で、下側が狭幅)に形成してもよく、保持片26の数は3つ に限らず4つ以上でもよく、保持片26の幅を少し大きくするならば保持片26 の数は2つでもよい。破断部は各保持片26の途中部に形成したり、3個所以下 又は3個所以上の狭幅部で構成してもよい。Explaining an example in which the above embodiment is partially modified, the inner cylinder portion 13 and the intermediate cylinder portion 14 of the cap body 10 may be formed in a solid shape instead of a cylindrical shape, and the holder 20 The holding pieces 26 of the spherical holding portion 24 may be formed in a slender trapezoidal shape (the upper side is wide and the lower side is narrow) instead of the parallel strips on both sides, and the number of the holding pieces 26 is limited to three. Alternatively, the number of holding pieces 26 may be four or more, and the number of holding pieces 26 may be two if the width of the holding pieces 26 is slightly increased. The fractured portion may be formed in the middle of each holding piece 26, or may be composed of three or less or three or more narrow portions.

以上説明したように、本考案に係るラムネ壜のキャップ構造によれば、ホルダ ーの環状部とフランジ部とでホルダーと壜口部間を確実にガス密状に封止でき、 パッキン部材で球体の外面側を確実にガス密状に封止できる。また、ホルダーへ 球体を装着する際、上方から簡単に装着できる。また、ホルダーの為の材料コス トを低減できる。 As described above, according to the Ramune bottle cap structure of the present invention, the annular portion and the flange portion of the holder can surely seal the space between the holder and the bottle mouth in a gas-tight manner, and the packing member makes the spherical body. The outer surface side of the can be reliably sealed in a gas-tight manner. Also, when attaching the sphere to the holder, it can be easily attached from above. Also, the material cost for the holder can be reduced.
【0029】 ホルダーに、環状部とフランジ部と球体保持部とを形成し、球体保持部に連結 部と複数の保持片を形成したので、球体の下半部を連結部と保持片とで確実に保 持でき、ハンドリング中の衝撃等で球体が勝手に外れることもない。 開栓の際には、連結部に形成した破断部の破断を介して球体を壜内へ確実に落 下させることができる。また、ラムネを飲む際には、連結部の破断部を破断させ るので、使用済みのキャップ構造を再使用するのを確実に防止できる。Since the annular portion, the flange portion and the sphere holding portion are formed on the holder, and the connecting portion and the plurality of holding pieces are formed on the sphere holding portion, the lower half portion of the sphere can be securely connected to the connecting portion and the holding piece. The sphere can be kept on its own, and the sphere will not come off due to impact during handling. At the time of opening the cap, the sphere can be reliably dropped into the bottle through the breaking of the breaking portion formed in the connecting portion. Further, when drinking Ramune, the breaking portion of the connecting portion is broken, so that it is possible to reliably prevent the reuse of the used cap structure.
