本発明は、瓶体の瓶口部を封止する瓶口用キャップに関する。
に関する。
The present invention relates to a bottle mouth cap for sealing the mouth of a bottle body.
Regarding.

一升瓶などの瓶体の瓶口部に栓体を組み付けて封止すると共に、栓体と瓶口部とを一緒に被覆する合成樹脂製のオーバーキャップを備えた瓶口用キャップが知られている(例えば特許文献1)。A bottle cap is known that is fitted with a stopper to seal the mouth of a bottle such as a one-liter bottle, and that is equipped with an overcap made of synthetic resin that covers both the stopper and the bottle mouth (for example, Patent Document 1).

特開2021-84674号公報JP 2021-84674 A

上記従来の瓶口用キャップにおける開封作業は、最初に封緘筒部3を主体とするオーバーキャップを開封し、次に栓体20を引き抜くことにより行われる。
しかし、従来の瓶口用キャップでは、瓶口部31に対する抜脱方向(上方向)における係合力は強いが周方向には回転しやすいのに対し、栓体20は瓶口部31の内周面に密着する構成であるため回転し難い状態にある。このため、オーバーキャップをその傾斜弱化部12に沿って摘み部17を旋回させることで封緘筒部3を取り除こうとすると、オーバーキャップ自体が空回りして上手く開封することができないことがある。
The opening operation of the above-mentioned conventional bottle cap is carried out by first opening the overcap, which is mainly composed of the sealing cylinder portion 3, and then pulling out thestopper body 20.
However, in a conventional bottle mouth cap, the engaging force in the removal direction (upward) with respect to thebottle mouth 31 is strong but it is easy to rotate in the circumferential direction, whereas thestopper 20 is difficult to rotate because it is configured to adhere closely to the inner peripheral surface of thebottle mouth 31. For this reason, when attempting to remove the sealing cylinder 3 by rotating theknob 17 along the weakenedslope 12 of the overcap, the overcap itself may spin freely and not be able to be opened properly.

そこで、オーバーキャップの空回りを防止するため、オーバーキャップを装着する際に、栓体20の上栓部21に対する締め付け力を増大させたところ、今度は栓体20がオーバーキャップと一緒に外れてしまうという問題があった。In order to prevent the overcap from spinning freely, the tightening force applied to theupper plug portion 21 of theplug body 20 was increased when the overcap was attached, but this resulted in theplug body 20 coming off together with the overcap.

本発明は、上記した従来技術における問題点を解消すべく、オーバーキャップを確実に取り除くことができると共に、このとき栓体が一緒に外れないようにした瓶口用キャップを創出することを課題とする。The present invention aims to solve the problems of the conventional technology described above by creating a bottle cap that allows the overcap to be removed reliably without removing the stopper at the same time.

上記課題を解決するための手段のうち、本発明の第1の手段は、
瓶口部内に嵌合する嵌合凸部及びその上部に設けられた上栓部を有する栓体と、頂部側壁を有して前記栓体の上面を覆う頂部及び前記瓶口部の外周面を被覆する封緘筒部を有すると共に前記頂部側壁と前記封緘筒部との間が破断可能に形成されたオーバーキャップと、を備える瓶口用キャップであって、
前記封緘筒部は前記瓶口部に係合する係合手段が設けられ、
前記頂部側壁の内周面に、傾斜状から成る複数の縦リブが周方向に沿って間欠的に形成されていることを特徴とする、と云うものである。
本発明の第1の手段では、複数の縦リブが上栓部に押し付けられた状態で組み付けられているので、開封時におけるオーバーキャップの空回りを防止できると共に、上栓部の外周面に対する引っ掛かりを無くすことができるため、栓体を瓶口部に残したままで頂部側壁を有する頂部のみを容易に取り除くことができる。
Among the means for solving the above problems, the first means of the present invention is
A cap for a bottle mouth, comprising: a stopper body having a fitting protrusion that fits into a bottle mouth and an upper stopper part provided on the upper part of the fitting protrusion; and an overcap having a top side wall and covering the top surface of the stopper body, and a sealing cylinder part that covers the outer peripheral surface of the bottle mouth, and the portion between the top side wall and the sealing cylinder part is formed so as to be breakable,
The sealing cylinder is provided with an engagement means for engaging with the bottle mouth,
The top side wall has an inner peripheral surface on which a plurality of inclined longitudinal ribs are intermittently formed along the circumferential direction.
In the first means of the present invention, multiple vertical ribs are assembled in a pressed state against the upper plug portion, thereby preventing the overcap from spinning freely when opened and eliminating the risk of it getting caught on the outer peripheral surface of the upper plug portion, making it possible to easily remove only the top portion having the top side wall while leaving the plug body in the bottle mouth.

本発明の第2の手段は、上記第1の手段に、傾斜状の縦リブは、上端が下端よりも径方向内側に突出するものである、との手段を加えたものである。The second aspect of the present invention is the above-mentioned first aspect, with the addition that the upper end of the inclined vertical rib protrudes radially inward beyond the lower end.

また本発明の第3の手段は、上記第1又は第2の手段に、頂部側壁と封緘筒部との間に破断可能な水平弱化部が形成されると共に、前記水平弱化部と前記封緘筒部の下端との間に破断可能な傾斜弱化部が形成されている、との手段を加えたものである。
上記手段では、オーバーキャップを構成する封緘筒部を頂部側壁から容易に分離し取り除くことができる。
The third means of the present invention is the above-mentioned first or second means, further comprising the addition of a breakable horizontal weakened portion between the top side wall and the sealing tube portion, and a breakable inclined weakened portion between the horizontal weakened portion and the lower end of the sealing tube portion.
In this manner, the sealing cylinder constituting the overcap can be easily separated and removed from the top side wall.

本発明では、複数の縦リブが上栓部に押し付けられた状態で組み付けられているため、摘み部を開栓方向に旋回させた際におけるーバーキャップの空回りを防止できる。
また縦リブは、上栓部の外周面に引っ掛かり難い構成であるため、栓体を瓶口部に残したままで頂部側壁を有する頂部のみを容易に取り除くことができる。
In the present invention, since the multiple vertical ribs are assembled in a state where they are pressed against the upper plug portion, it is possible to prevent the overcap from spinning freely when the knob portion is rotated in the plug opening direction.
Furthermore, since the vertical ribs are configured so as not to get caught on the outer peripheral surface of the upper plug portion, it is possible to easily remove only the top portion having the top side wall while leaving the plug in the mouth of the bottle.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a bottle mouth cap according to one embodiment of the present invention, showing the state in which it is attached to a bottle mouth, FIG. 2 is a half-longitudinal cross-sectional view of FIG. 1, and FIG. 3 is a half-sectional perspective view of the bottle mouth cap showing its internal structure.
In the following, the direction along the cap axis O will be referred to as the axial direction, the up-down direction or the height direction, the direction perpendicular to the cap axis O will be referred to as the radial direction, and the direction going around the cap axis O will be referred to as the circumferential direction (opening direction or reverse opening direction).

本発明の瓶口用キャップ1は、後述する栓体20の上面を覆う頂部11及び瓶口部31の外周面を被覆する円筒状の封緘筒部13を有して全体が合成樹脂材料で形成されたオーバーキャップ10と、瓶口部31に対して着脱自在に嵌合可能に設けられた栓体20とを有して構成される。The bottle mouth cap 1 of the present invention is composed of anovercap 10 made entirely of a synthetic resin material, with atop portion 11 covering the upper surface of a stopper body 20 (described later) and a cylindricalsealing tube portion 13 covering the outer periphery of thebottle mouth portion 31, and astopper body 20 that is provided so as to be detachably fitted to thebottle mouth portion 31.

図1乃至図3に示すように、頂部11はその上面に段凹部を有すると共に、その外縁部には頂部側壁12が垂下設されている。頂部側壁12の下端12Aには、破断可能な細溝で形成された水平弱化部13aが周設されると共に、水平弱化部13aを介して封緘筒部13が連設されている。また封緘筒部13には、破断可能な細溝から成り且つ水平弱化部13aから封緘筒部13の下端13Aに向かって傾斜状に延びる傾斜弱化部13bが形成されており、傾斜弱化部13bの下端には摘み部14が設けられている。As shown in Figures 1 to 3, thetop 11 has a stepped recess on its upper surface, and atop side wall 12 is attached to its outer edge. A horizontal weakenedportion 13a formed of a breakable narrow groove is attached to thelower end 12A of thetop side wall 12, and thesealing tube portion 13 is connected to the horizontal weakenedportion 13a via the horizontal weakenedportion 13a. Thesealing tube portion 13 is also formed with an inclined weakenedportion 13b, which is made of a breakable narrow groove and extends at an angle from the horizontal weakenedportion 13a toward thelower end 13A of thesealing tube portion 13, and aknob portion 14 is provided at the lower end of the inclined weakenedportion 13b.

図2及び図3に示すように、封緘筒部13の内周面には径方向内側に向かって突出する複数の抜止め凸部15が周方向に所定の長さを有して間欠的に形成されている。また封緘筒部13の内周面で凸部15よりも下方の位置には、径方向内内側に向かって突出する複数の凸部本体16が、凸部15同様に周方向に所定の長さを有して間欠的に形成されている。As shown in Figures 2 and 3, a number ofanti-slip projections 15 that protrude radially inward are intermittently formed on the inner circumferential surface of thesealing tube portion 13, each having a predetermined length in the circumferential direction. In addition, a number ofprojection bodies 16 that protrude radially inward are intermittently formed on the inner circumferential surface of thesealing tube portion 13 below theprojections 15, each having a predetermined length in the circumferential direction, similar to theprojections 15.

また各凸部本体16の下方の位置には、その肉厚を薄肉状に形成することで弾性変形による可撓性を備えた複数のフラップ17が、封緘筒部13の内周面に一体に形成されている。フラップ17の周方向の長さは、凸部本体16の周方向の長さとほぼ等しく、径方向の先端17a側ほど周方向の長さが短くなる平面視略台形形状である。フラップ17は、封緘筒部13の内周面に対して片持ち支持状態で連設されており、基端側の連結部17bを支点に先端17aが上下方向に揺動可能に形成されている。瓶口用キャップ1を瓶口部31への組み付ける前において、フラップ17は、図2の破線に及び図3に示すように封緘筒部13の内周面から斜め下方に向かって傾斜状に延びている。In addition, below each of theprotruding body 16, a number offlaps 17, which are flexible due to elastic deformation due to their thin wall thickness, are integrally formed on the inner circumferential surface of thesealing tube 13. The circumferential length of theflaps 17 is approximately equal to the circumferential length of theprotruding body 16, and the circumferential length becomes shorter toward theradial tip 17a side, forming a generally trapezoidal shape in a plan view. Theflaps 17 are connected to the inner circumferential surface of thesealing tube 13 in a cantilevered state, and thetip 17a is formed so that it can swing up and down with the connectingportion 17b on the base end side as a fulcrum. Before the bottle mouth cap 1 is attached to thebottle mouth 31, theflaps 17 extend obliquely downward from the inner circumferential surface of thesealing tube 13 as shown by the dashed line in FIG. 2 and in FIG. 3.

更に頂部側壁12の内周面には、頂部11の下面から続く複数の縦リブ18が周方向に所定の間隔を有して間欠的に形成されている。縦リブ18は頂部11の下面側に位置する上端18aの方が、水平弱化部13a側に位置する下端18bよりも径方向内側に突出する傾斜状を有して形成されている。Furthermore, multiplevertical ribs 18 extending from the underside of thetop 11 are intermittently formed at a predetermined interval in the circumferential direction on the inner peripheral surface of thetop sidewall 12. Thevertical ribs 18 are formed with an inclination such that theupper end 18a located on the underside of the top 11 protrudes radially inward more than thelower end 18b located on the horizontal weakenedportion 13a side.

ここで、図2に示すように、栓体20は、最大外径寸法を有して構成される上栓部21と、その下部に設けられた段差部23を介して連設された小径の凸形状からなる嵌合凸部22とを有して一体に形成されている。栓体20は、嵌合凸部22が瓶体30の瓶口部31内に挿入されて内周面に対して密嵌合すると共に、段差部23の下端が瓶口部31の上端面32に当接することにより瓶体30を封止する。As shown in FIG. 2, thestopper 20 is integrally formed with anupper stopper portion 21 having a maximum outer diameter and a small-diameterconvex fitting protrusion 22 connected to theupper stopper portion 21 via astepped portion 23 provided at the lower portion. Thestopper 20 seals thebottle 30 when thefitting protrusion 22 is inserted into themouth 31 of thebottle 30 and fits tightly against the inner peripheral surface, and when the lower end of thestepped portion 23 abuts against theupper end surface 32 of thebottle mouth 31.

瓶口用キャップ1を瓶口部31への組み付けは、オーバーキャップ10内に栓体20を配置した瓶口用キャップ1を瓶口部31に対して打栓することにより行われる。
栓体20をオーバーキャップ10内に配置すると、抜止め凸部15が上栓部21と嵌合凸部22との間に形成された段差部23に向かって突設する状態に設定される。栓体20をオーバーキャップ10内に配置した状態において、栓体20がキャップ軸Oに沿って軸方向に移動した場合には、上栓部21の下端に抜止め凸部15が当接する。このため、打栓前及び打栓中において、栓体20がオーバーキャップ10内から容易に抜け出てしまうことを防止することが可能である。
The bottle cap 1 is attached to thebottle mouth portion 31 by plugging the bottle cap 1 with thestopper body 20 placed inside theovercap 10 onto thebottle mouth portion 31.
When theplug 20 is placed in theovercap 10, theanti-slip protrusion 15 is set in a state where it protrudes toward thestep 23 formed between theupper plug portion 21 and thefitting protrusion 22. When theplug 20 moves axially along the cap axis O while placed in theovercap 10, theanti-slip protrusion 15 comes into contact with the lower end of theupper plug portion 21. This makes it possible to prevent theplug 20 from easily coming out of theovercap 10 before and during plugging.

瓶口部31に対して瓶口用キャップ1を打栓すると、斜め下方に延びていたフラップ17に瓶体30の上端面32が当接する。更に瓶口用キャップ1が下方に移動すると、瓶口部31がオーバーキャップ10内を上方に向かって相対的に移動するため、フラップ17が連結部17bを支点として上方に向かって折り返され、その上部に設けられた凸部本体16の表面を覆うように重なる。When the bottle mouth cap 1 is fitted onto thebottle mouth 31, theupper end surface 32 of thebottle body 30 comes into contact with theflap 17 that extends diagonally downward. When the bottle mouth cap 1 moves further downward, thebottle mouth 31 moves relatively upward within theovercap 10, so that theflap 17 is folded upward with the connectingportion 17b as a fulcrum, and overlaps to cover the surface of the protruding portionmain body 16 provided at its upper part.

更に打栓が進んで瓶口部31がオーバーキャップ10内を上方に移動すると、図2に示すように、フラップ17は瓶口部31の外周面と封緘筒部13の内周面との間に挟持され、凸部本体16の表面に重なる状態を維持しながら瓶口部31の外周面に設けられた断面視凹曲面状に周設された被係止凹部33内に凸部本体16と共に嵌り込む。この状態では、凸部本体16とその上に重なったフラップ17とが一緒に被係止凹部6内に圧入されるため、瓶口部31に対して瓶口用キャップ1を構成するオーバーキャップ10を高い係合力で嵌着させることができる。本発明における実施形態では、凸部本体16とフラップ17とは瓶口部31に対する瓶口用キャップ1の係合力を高めるための係合手段40を構成している。このように、本発明の瓶口用キャップ1では、オーバーキャップ10が十分に高い係合力を発揮することが可能であるため、例えば瓶体30内の内圧が上昇しても栓体20の上方への移動を抑え込み、瓶口用キャップ1が開栓してしまうことがない。As the stoppering process continues and thebottle mouth 31 moves upward within theovercap 10, as shown in FIG. 2, theflap 17 is sandwiched between the outer circumferential surface of thebottle mouth 31 and the inner circumferential surface of thesealing tube 13, and fits together with theconvex body 16 into the interlockingrecess 33, which is provided on the outer circumferential surface of thebottle mouth 31 and has a concave curved surface in cross section, while maintaining a state of overlapping with the surface of theconvex body 16. In this state, theconvex body 16 and theflap 17 overlapping thereon are pressed together into the interlocking recess 6, so that theovercap 10 constituting the bottle mouth cap 1 can be fitted with a high interlocking force to thebottle mouth 31. In the embodiment of the present invention, theconvex body 16 and theflap 17 constitute an interlocking means 40 for increasing the interlocking force of the bottle mouth cap 1 to thebottle mouth 31. In this way, with the bottle cap 1 of the present invention, theovercap 10 is able to exert a sufficiently high engagement force, so that even if the internal pressure inside thebottle body 30 rises, the upward movement of thestopper body 20 is suppressed, and the bottle cap 1 will not open.

そして、瓶口部31に対する瓶口用キャップ1の組み付きが完了すると、上記のように、嵌合凸部22が瓶体30の瓶口部31内に挿入されて内周面に対して密嵌合すると共に、段差部23の下端が瓶口部31の上端面32に当接することにより瓶体30を封止する。そして、オーバーキャップ10の頂部11の下面が栓体20の上面に当接する。When the attachment of the bottle mouth cap 1 to thebottle mouth 31 is completed, as described above, thefitting protrusion 22 is inserted into thebottle mouth 31 of thebottle body 30 and fits tightly against the inner peripheral surface, and the lower end of thestep portion 23 abuts against theupper end surface 32 of thebottle mouth 31, sealing thebottle body 30. Then, the lower surface of thetop 11 of theovercap 10 abuts against the upper surface of thestopper body 20.

またこの状態では、縦リブ18が、栓体20の上栓部21の外周面に当接している。より詳しくは、縦リブ18は、上栓部21の外周面に対し、径方向内側への突出量が大きい上端18a側が大きな加圧力で当接し、突出量の小さい下端18b側が小さな加圧力で当接している。このため、特に縦リブ18の上端18aによって上栓部21の外周面との間における周方向の抵抗を増大させることが可能となっている。In this state, thevertical ribs 18 are in contact with the outer peripheral surface of theupper plug portion 21 of theplug body 20. More specifically, theupper end 18a of thevertical ribs 18, which protrudes radially inwardly to a large extent, is in contact with the outer peripheral surface of theupper plug portion 21 with a large pressure force, and thelower end 18b, which protrudes less radially inward, is in contact with the outer peripheral surface of theupper plug portion 21 with a small pressure force. Therefore, it is possible to increase the circumferential resistance between the outer peripheral surface of theupper plug portion 21 and theupper end 18a of thevertical ribs 18 in particular.

次に、上記構成からなる瓶口用キャップ1の開封について説明する。
図4は開封作業時の様子を示す瓶口用キャップの縦断面図である。
使用者は、一方の片手で瓶口部31を保持し、他方の手で摘み部14を摘まみながら図1に矢印で示す開封方向に沿って一周に渡って旋回させる作業を行う。すると、傾斜弱化部13bに続いて水平弱化部13aを破断させることができ、水平弱化部13aよりも下側に設けられている封緘筒部13を頂部側壁12の下端12Aから分離除去することができる。この際、上記の縦リブ18が、オーバーキャップ10と栓体20との間の周方向における抵抗を増大させているため、オーバーキャップ10は空回りすることなく、封緘筒部13に設けられた傾斜弱化部13b及び水平弱化部13aの破断を確実に行うことができる。
Next, the opening of the bottle cap 1 having the above-mentioned structure will be described.
FIG. 4 is a vertical sectional view of a bottle cap showing the state during opening operation.
The user holds thebottle mouth 31 with one hand and pinches theknob 14 with the other hand while rotating the bottle in the opening direction shown by the arrow in Fig. 1. This breaks the inclined weakenedportion 13b and then the horizontal weakenedportion 13a, and the sealingcylinder portion 13 located below the horizontal weakenedportion 13a can be separated and removed from thelower end 12A of thetop side wall 12. At this time, since thevertical rib 18 increases the resistance in the circumferential direction between theovercap 10 and thestopper 20, theovercap 10 does not spin freely, and the inclined weakenedportion 13b and the horizontal weakenedportion 13a on the sealingcylinder portion 13 can be broken reliably.

また封緘筒部13を取り除いた後は、栓体20の上栓部21を覆う頂部側壁12を有する頂部11を取り外す作業を行う。この作業は、図4に示すように、頂部側壁12を有する頂部11を傾けた状態で持ち上げ、先に持ち上がった一方(図4では右側)の頂部側壁12の下端12Aを上栓部21の外周面から外し、続いて頂部側壁12を有する頂部11の全体を栓体20の上栓部21から取り外す。After removing the sealingcylinder portion 13, thetop portion 11 having thetop sidewall 12 that covers theupper plug portion 21 of theplug body 20 is removed. This is done by lifting thetop portion 11 having thetop sidewall 12 in a tilted state as shown in FIG. 4, removing thelower end 12A of thetop sidewall 12 that was lifted first (the right side in FIG. 4) from the outer periphery of theupper plug portion 21, and then removing the entiretop portion 11 having thetop sidewall 12 from theupper plug portion 21 of theplug body 20.

ここで、上栓部21の外周面に対して縦リブ18はその全体が均等の加圧力で当接しているのではなく、突出量の小さい縦リブ18の下端18bを当接しないようにしている。
なお、縦リブ18の下端18bを上端18aよりも小さい加圧力で当接するようにしてもよい。
Here, the entirevertical rib 18 is not in contact with the outer circumferential surface of theupper plug portion 21 with uniform pressure, but thelower end 18b of thevertical rib 18, which has a small protruding amount, is not in contact with the outer circumferential surface of theupper plug portion 21.
Thelower ends 18b of thevertical ribs 18 may be abutted with a smaller pressure than theupper ends 18a.

そして、頂部側壁12を有する頂部11を傾けたときに、最も引っ掛かりやすい部分は先に持ち上げた側の頂部側壁12の下端12Aであるところ、この下端12Aの内周面では縦リブ18の下端18bが上栓部21の外周面に当接しない。よって、頂部側壁12を有する頂部11を傾けて取り外す際に、縦リブ18が栓体20の上栓部21の外周面に引っ掛かり難くすることができる。よって、オーバーキャップ10の開封作業において、封緘筒部13を取り除いた後、頂部側壁12を有する頂部11を取り外す際に栓体20が一緒に外れてしまうことを防止できる。すなわち、栓体20を瓶口部31に残した状態で、オーバーキャップ10のみを容易且つ確実に取り除くことができる。尚、その後は、瓶口部31から栓体20のみを単独で引き抜くことが可能である。When the top 11 having thetop sidewall 12 is tilted, the part that is most likely to get caught is thelower end 12A of thetop sidewall 12 on the side that was lifted first, but thelower end 18b of thevertical rib 18 does not abut the outer circumferential surface of theupper plug portion 21 on the inner circumferential surface of thislower end 12A. Therefore, when the top 11 having thetop sidewall 12 is tilted and removed, thevertical rib 18 is less likely to get caught on the outer circumferential surface of theupper plug portion 21 of theplug 20. Therefore, in the opening operation of theovercap 10, after removing the sealingtube portion 13, theplug 20 can be prevented from coming off together when removing the top 11 having thetop sidewall 12. In other words, theovercap 10 can be easily and reliably removed while theplug 20 remains in thebottle mouth portion 31. After that, it is possible to pull out only theplug 20 from thebottle mouth portion 31 alone.

以上、実施例に沿って本発明の構成とその作用効果について説明したが、本発明の実施の形態は上記実施例に限定されるものではない。
例えば縦リブを上栓部21の外周面に周方向に沿って間欠的に形成する構成としても良い。
Although the configuration and the effects of the present invention have been described above based on the embodiments, the present invention is not limited to the above embodiments.
For example, vertical ribs may be intermittently formed on the outer circumferential surface of theupper plug portion 21 in the circumferential direction.
