Description

本発明は、打栓式キャップなのに素手などでも容易に開封でき、且つ開封後にも容易に閉じることが出来る易開封型打栓式キャップに関するものであり、より詳しくは、キャップ本体と、このキャップ本体に嵌合する外筒部と、からなり、外筒部がキャップ本体より上方に位置し両者が破断可能なブリッジで一体に成形されて、容器口部にキャップ本体を被せた後、キャップ本体に外筒部を嵌合し、容器口部にキャップ本体の嵌合部をカシメ押圧状態にして、容器口部とキャップ本体とを液密に保持することができる易開封型打栓式キャップに関する。   TECHNICAL FIELD The present invention relates to an easy-opening-type plug cap that can be easily opened even with a bare hand even though it is a cap-type cap, and can be easily closed after opening, and more specifically, a cap body and the cap body. And the outer cylinder portion is located above the cap body and is formed integrally with a breakable bridge, and the cap body is put on the container mouth, and then the cap body The present invention relates to an easy-opening type plug cap that can fit an outer cylinder part, place the fitting part of the cap body into a caulking pressing state in the container mouth part, and hold the container mouth part and the cap body in a liquid-tight state.

所謂打栓式キャップは、キャップ打栓機により打栓すれば、容器の口部に容易に液密に嵌めることが出来るため広く普及している。しかしながら、打栓式キャップと容器口部との液密度を高めるために双方の嵌合部形状を強く密着させる寸法関係に設ける必要があり、その結果、いきおい打栓力が強くならざるを得ず、逆に、開封時に強い力でないと開けることが出来ず、さらに開封後は閉じることが出来ないことになる。加えて、それらの力に耐えるだけの強度が、打栓式キャップおよび容器口部の双方に求められることになる。   A so-called cap-type cap is widely used because it can be easily liquid-tightly fitted into the mouth of a container when plugged by a cap-plugging machine. However, in order to increase the liquid density between the cap-type cap and the container mouth, it is necessary to provide a dimensional relationship in which the shapes of both fitting portions are closely attached, and as a result, the powerful plugging force must be strong. On the contrary, it cannot be opened unless it is a strong force at the time of opening, and it cannot be closed after opening. In addition, strength sufficient to withstand these forces is required for both the stopper cap and the container mouth.

このような観点から、閉栓及び開封を容易にした打栓式キャップを指向するようになって、このようなキャップとしては、容器口部に嵌合した栓部材を覆うように装着したものであって、天板部の周縁に複数の係止片を周方向に配設した係止部材と、この複数の係止片を外周側に装着したホルダー部材とを備え、各係止片は、天板部周縁から下方に延設し、且つ上下方向中途部の薄肉の屈曲部を介して上側部と下側部とを接続してなり、上側部は、その外周側にホルダー部材を装着した状態で容器口部に下側から係止し、ホルダー部材は係止部材に対して上下に相対移動可能であり、ホルダー部材の下端が係止片の上側部よりも上方に相対移動することを阻止するように係止する係止凸部を、ホルダー部材及び／または係止部材に設けているものが知られている（例えば、特許文献１参照）。   From such a point of view, the cap-type cap that facilitates closing and opening is directed to a cap that is attached to cover the plug member fitted to the container mouth. A locking member having a plurality of locking pieces arranged in the circumferential direction on a peripheral edge of the top plate portion, and a holder member having the plurality of locking pieces mounted on the outer peripheral side. A state in which the upper part and the lower part are connected to each other through a thin bent part in the middle in the vertical direction, extending downward from the periphery of the plate part, and the upper part is in a state in which a holder member is mounted on the outer peripheral side thereof The holder member can be moved up and down relative to the locking member, and the lower end of the holder member is prevented from moving upward relative to the upper side of the locking piece. A locking projection is provided on the holder member and / or the locking member. It is known to have (for example, see Patent Document 1).

また、打栓式キャップでもあるヒンジキャップは、キャップ本体と上蓋とがヒンジにより連結され、キャップ本体のスカート部に、これを外側から覆う２重の第１筒状側壁および第２筒状側壁を備え、内側の第１筒状側壁がその下端または上端においてスカート部の下端または上端と連続し、外側の第２筒状側壁がその上端または下端において第１筒状側壁の上端または下端と連続しており、上蓋が第２筒状側壁の上端でヒンジ連結され、そのヒンジ形成位置を除いた位置におけるスカート部の下端または上端と第１筒状側壁の下端または上端の連結部に破断不可能な接続部が形成されている。これにより、内容物のホット充填時における密封性を確保し、内容物を消費した後、容器口部からヒンジキャップを容易に取り外せて、分別廃棄性に優れたものとなっている（例えば、特許文献２参照）。   Further, the hinge cap, which is also a cap-type cap, has a cap body and an upper lid connected by a hinge, and the skirt portion of the cap body is provided with a double first cylindrical side wall and a second cylindrical side wall that cover this from the outside. The inner first cylindrical side wall is continuous with the lower end or upper end of the skirt portion at its lower end or upper end, and the outer second cylindrical side wall is continuous with the upper end or lower end of the first cylindrical side wall at its upper end or lower end. The upper lid is hinged at the upper end of the second cylindrical side wall and cannot be broken at the lower end or upper end of the skirt portion and the lower end or upper end connecting portion of the first cylindrical side wall at a position excluding the hinge forming position. A connecting portion is formed. As a result, the sealability during hot filling of the contents is ensured, and after the contents are consumed, the hinge cap can be easily removed from the container mouth, and the waste is excellent in separation and disposal (for example, patents) Reference 2).

特許第４５２６４８０号公報Japanese Patent No. 4526480 特開２０１２−１２１６２４号公報JP 2012-121624 A

特許文献１のキャップは、まず、容器口部にゴム製の栓部材を嵌合し、その後、栓部材を覆うように打栓機などにより装着したものであるから、栓部材とキャップとの２ピースとなり、そのことにより製作面および容器に内容物を充填した後の閉栓面で不利となる。そして、開栓は、キャップを手指で上方に引き上げ、それと共に栓部材も嵌脱するものであるために把持面積が大きいからと言って、開栓がそれほど容易とはならない。さらに、このキャップには、いたずら防止機能が無いから、容器口部あるいは容器全体ごと別途包装する必要がある。   The cap of Patent Document 1 is a member in which a rubber plug member is first fitted into a container mouth, and is then mounted by a stopper or the like so as to cover the plug member. It becomes a piece, which is disadvantageous in terms of the production surface and the closure surface after filling the contents with the container. And, in order to open the cap, it is not easy to open the cap because the gripping area is large because the cap is lifted upward with fingers and the plug member is fitted and detached together. Furthermore, since this cap has no function to prevent tampering, it is necessary to wrap the entire container mouth or the entire container separately.

特許文献２の打栓式のヒンジキャップは、キャップ本体のスカート部を、外側から覆う内側の第１筒状側壁および外側の第２筒状側壁の２重でカシメ状態にして、容器口部とキャップ本体とを液密に保持する点で優れ、上蓋を引き上げ第１および第２筒状側壁のカシメ状態を解除してやれば、容器口部からヒンジキャップを取り外せて都合が良いものである。しかしながら、構造上第１および第２筒状側壁のカシメ力は、それほど強いものではないから、上蓋の内面から垂下させたインナーリングを必要とし、このインナーリングと第１および第２筒状側壁のカシメ力との複合により、特許文献２のヒンジキャップは容器口部に液密を保持することになって、容器口部からキャップを外す際の制約要素となったり、インナーリングの存在によるコスト高の要因となる虞がある。   The stopper-type hinge cap of Patent Document 2 is configured such that the skirt portion of the cap body is crimped with a double of an inner first cylindrical side wall and an outer second cylindrical side wall covering from the outside, It is excellent in that the cap main body is liquid-tightly held, and if the upper lid is pulled up to release the caulking state of the first and second cylindrical side walls, the hinge cap can be removed from the container mouth, which is convenient. However, since the caulking force of the first and second cylindrical side walls is not so strong in structure, an inner ring suspended from the inner surface of the upper lid is required, and the inner ring and the first and second cylindrical side walls Due to the combination with the caulking force, the hinge cap of Patent Document 2 maintains liquid tightness at the container mouth, which becomes a limiting factor when removing the cap from the container mouth, and is expensive due to the presence of the inner ring. There is a risk of this.

そこで、本発明の目的は、１ピース成形が可能で、比較的弱い力でも容器の口部に打栓して閉栓することが出来、開封時にも、容器の口部から容易に取り外すことが出来て、しかもいたずら防止機能を有し、開栓後のリシールも容易であって、製作面および利用面でも有利となる易開封型打栓式キャップを提供することにある。   Therefore, the object of the present invention is that one-piece molding is possible, it can be plugged into the mouth of the container even with a relatively weak force, and can be easily removed from the mouth of the container even when opened. In addition, it is an object of the present invention to provide an easy-opening plug cap that has a function to prevent tampering, is easy to reseal after opening, and is advantageous in terms of production and use.

そして、このスカート壁３の下端部は、軸方向スリット８により複数に分割された易導入壁９に形成されている、これら各易導入壁９は、外方に末広がりにするための屈曲部９ａがあり、この屈曲部９ａよりも先端側内周面に容器口部６の鍔部６ａに係合するための突起９ｂがある。なお、屈曲部９ａは、外筒部１５を押し下げる様に打栓した際変形して、突起９ｂが容器口部６の鍔部６ａに係合し、嵌合部７をカシメ押圧状態にすることが必要であるため、薄肉に形成され変形し易くなっている。   And the lower end part of this skirt wall 3 is formed in the easy introduction wall 9 divided | segmented into plurality by the axial direction slit 8, These each easy introduction wall 9 is the bending part 9a for making it spread outward outward There is a projection 9b for engaging with the flange portion 6a of the container mouth portion 6 on the inner peripheral surface on the distal end side than the bent portion 9a. The bent portion 9a is deformed when the outer tube portion 15 is pushed down so that the projection 9b engages with the flange portion 6a of the container mouth portion 6 so that the fitting portion 7 is in a caulking press state. Therefore, it is thin and easily deformed.

前記外筒部１５は、既述のとおり、外筒１２およびその下端にあるタンパーエビデントバンド１４からなって、このタンパーエビデントバンド１４の内周面に縦方向のリブ２３を設けている。容器５の口部６とキャップ本体１０との閉栓時に、タンパーエビデントバンド１４の縦リブ２３が易導入壁９の軸方向スリット８に嵌り込み、外筒部１５とキャップ本体１０とが空回りしないようにされている。したがって、このタンパーエビデントバンド１４を除去しない限り、容器口部６からキャップ１を取り外すことは出来ないので、このタンパーエビデントバンド１４により、故意や過失による開封の有無を確認することができる。そして、このタンパーエビデントバンド１４の端部には引剥し開始部２４があり、開封時に、この引剥し開始部２４を手指にて周方向に沿って引き剥がし方向に引っ張れば、外筒１２下端とタンパーエビデントバンド１４とを繋いでいる弱化部１３を容易に破断出来て、外筒１２下端からタンパーエビデントバンド１４を外すことが出来る。なお、図１において、２５はすべり止めである。   As described above, the outer cylinder portion 15 includes the outer cylinder 12 and the tamper evidence band 14 at the lower end thereof, and the ribs 23 in the vertical direction are provided on the inner peripheral surface of the tamper evidence band 14. When the mouth portion 6 of the container 5 and the cap body 10 are closed, the vertical ribs 23 of the tamper evident band 14 are fitted into the axial slits 8 of the easy-introduction wall 9 so that the outer cylinder portion 15 and the cap body 10 do not idle. Has been. Therefore, unless the tamper evident band 14 is removed, the cap 1 cannot be removed from the container mouth portion 6, so it is possible to confirm whether the tamper evidence band 14 has been opened intentionally or accidentally. The tamper-evident band 14 has a peeling start portion 24 at the end thereof. When opening, the pulling start portion 24 is pulled in the peeling direction along the circumferential direction with a finger. And the weakened portion 13 connecting the tamper evidence band 14 can be easily broken, and the tamper evidence band 14 can be removed from the lower end of the outer cylinder 12. In FIG. 1, reference numeral 25 denotes an anti-slip.

次に、上記構成になる易開封型打栓式キャップ１の利用方法について説明する。
まず、容器５の口部６にサイズの合う、図１に示す易開封型打栓式キャップ１を選択する。次に、容器５内に内容液を充填したあと、容器口部６に易開封型打栓式キャップ１を被せて、その容器口部６にキャップ本体１０の嵌合部７を嵌合させた状態にした後（図２、３参照）、外筒部１５を押し下げ打栓するとブリッジ１６を破断し、キャップ本体１０と外筒部１５とが分離すると共にキャップ本体１０に外筒部１５を嵌合することになるが、その際、外筒部１５の４つの凸条１１は、４つの縮径部３Ａを通過して凹溝４の下端側に到達して、凹溝４と螺合状態になる。そして、縮径部３Ａは、スカート壁３の外径より縮径され且つ斜め上方に傾斜して延在する凹溝４の下端側に位置していることが重要である。また、凸条１１は縮径部３Ａの上方位置に対応して形成されている（図１−破線で示す凸条１１参照）。このような位置関係となるように両者を配置して一体成形することで、外筒部１５を押し下げ打栓する際、凸条１１が凹溝４の下端側にスムーズに誘導され、打栓が良好となるのである（図７−破線で示す凸条１１参照）。一方、外筒部１５のタンパーエビデントバンド１４は、外方に末広がりしている各易導入壁９を、それらの各屈曲部９ａを基点として変形させて窄ませ、容器口部６の鍔部６ａに各易導入壁９の突起９ｂを係合させて、容器口部６に嵌合部７をカシメ押圧状態にして、容器口部６とキャップ本体１０とを液密に保持して閉栓を終了する（図４、５、６、７を順次参照）。その後、必要に応じて易開封型打栓式キャップ１を装着した容器５を包装して最終製品とする。なお、キャップ本体１０の易導入壁９が、軸方向スリット８により複数に分割され、しかも外方に末広がりに形成されているから、容器口部６に嵌合部７を容易に嵌合でき、加えてその位置決めも極めて容易となっている。 Next, the utilization method of the easy-opening type cap 1 having the above-described configuration will be described.
First, the easy-opening type cap 1 shown in FIG. 1 that matches the size of the mouth 6 of the container 5 is selected. Next, after filling the container 5 with the content liquid, the container mouth portion 6 was covered with the easy-opening stopper cap 1 and the fitting portion 7 of the cap body 10 was fitted to the container mouth portion 6. After the state (see FIGS. 2 and 3), when the outer cylinder portion 15 is pushed down and plugged, the bridge 16 is broken, and the cap body 10 and the outer cylinder portion 15 are separated, and the outer cylinder portion 15 is fitted into the cap body 10. At that time, the four ridges 11 of the outer cylindrical portion 15 pass through the four reduced diameter portions 3A and reach the lower end side of the concave groove 4, and are screwed with the concave groove 4. become. It is important that the reduced diameter portion 3A is positioned on the lower end side of the concave groove 4 which is reduced in diameter from the outer diameter of the skirt wall 3 and extends obliquely upward. Moreover, the protruding item | line 11 is formed corresponding to the upper position of the diameter reducing part 3A (refer the protruding item | line 11 shown with a broken line in FIG. 1). By arranging both of them so as to be in such a positional relationship and integrally forming them, when the outer cylinder portion 15 is pushed down and plugged, the ridges 11 are smoothly guided to the lower end side of the groove 4 and the plugging is performed. It becomes good (see FIG. 7-ridge 11 shown by a broken line). On the other hand, the tamper-evidence band 14 of the outer cylinder part 15 is formed by deforming and constricting the respective easy-introduction walls 9 spreading outward from the respective bent parts 9a as base points. 6a is engaged with the protrusion 9b of each easy-introduction wall 9, the fitting part 7 is squeezed and pressed into the container mouth part 6, and the container mouth part 6 and the cap body 10 are held in a liquid-tight state to close the cap. Finish (refer to FIGS. 4, 5, 6, and 7 in order). Then, if necessary, the container 5 equipped with the easy-open cap-type cap 1 is packaged to obtain a final product. In addition, since the easy introduction wall 9 of the cap body 10 is divided into a plurality by the axial slit 8 and is formed to spread outward, the fitting portion 7 can be easily fitted to the container mouth portion 6. In addition, the positioning is very easy.

製品の消費に際しては、易開封型打栓式キャップ１の部分を裸出し、容器口部６から易開封型打栓式キャップ１を開け得る状態にする。そして、開封するには、まず、タンパーエビデントバンド１４の引剥し開始部２４を手指にて掴み、引き剥がし方向に引っ張れば、外筒１２下端とタンパーエビデントバンド１４とを繋いでいる弱化部１３を破断して、外筒１２下端からタンパーエビデントバンド１４を外すことが出来る（図８参照）。次に、その外筒１２を開封方向に回すと、既述のとおり、キャップ本体１０の凹溝４と外筒１２の凸条１１とが螺合状態にあるから、外筒１２がキャップ本体１０に対して上昇して、容器口部６と嵌合部７とのカシメ押圧状態を解消することになって（図９参照）、容器口部６からキャップ本体１０および外筒１２を外すことが出来る。   When the product is consumed, the portion of the easy-opening stopper-type cap 1 is bare, and the easily-openable stopper-type cap 1 is opened from the container opening 6. In order to open the bag, first, the peeling start portion 24 of the tamper evident band 14 is grasped with fingers, and if it is pulled in the peeling direction, the weakened portion connecting the lower end of the outer cylinder 12 and the tamper evidence band 14. 13 can be broken to remove the tamper evidence band 14 from the lower end of the outer cylinder 12 (see FIG. 8). Next, when the outer cylinder 12 is turned in the opening direction, as described above, the concave groove 4 of the cap body 10 and the convex strips 11 of the outer cylinder 12 are in a threaded state. The caulking pressing state between the container mouth part 6 and the fitting part 7 is canceled (see FIG. 9), and the cap body 10 and the outer cylinder 12 can be removed from the container mouth part 6. I can do it.

そして、容器５内に内容物が残り容器口部６をリシールしたい場合は、容器口部６にキャップ本体１０の嵌合部７を嵌合させた状態で外筒１２を閉栓方向に回せば、再び外筒１２により容器口部６にキャップ本体１０の嵌合部７をカシメ押圧状態にして、容器口部６とキャップ本体１０とを液密に保持してリシールすることが出来る。   Then, if the contents remain in the container 5 and it is desired to reseal the container mouth part 6, the outer cylinder 12 is turned in the closing direction with the fitting part 7 of the cap body 10 fitted to the container mouth part 6. The fitting portion 7 of the cap main body 10 is again crimped to the container mouth 6 by the outer cylinder 12, and the container mouth 6 and the cap main body 10 can be held in a liquid-tight state and resealed.

以上、本発明の実施例１を説明したが、具体的な構成はこれに限定されず、本発明の要旨を逸脱しない範囲での変更は、適宜可能であることが理解されるべきである。   While the first embodiment of the present invention has been described above, it should be understood that the specific configuration is not limited to this, and that modifications can be made as appropriate without departing from the scope of the present invention.

本発明の易開封型打栓式キャップは、１ピース成形が可能で、比較的弱い力でも容器の口部に打栓して閉栓出来、開封時に容器の口部から容易に取り外すことが出来て、しかもいたずら防止も出来、開栓後のリシールも容易であり、製作面および利用面で有利にしたいような場合に、その利用可能性が極めて高くなる。   The easy-opening type cap of the present invention can be molded in one piece, can be plugged into the mouth of the container even with a relatively weak force, and can be easily removed from the mouth of the container when opened. In addition, tampering can be prevented, resealing after opening is easy, and the possibility of use becomes extremely high when it is desired to be advantageous in terms of production and use.
