更に、本発明者等は、上記合成樹脂製容器蓋の改良として、先に、特願２００８−１７８２２５において、非破断接続片の各々を傾動方向が相互に逆である２個の傾斜部を含む形態にすることを提案した。更に詳しくは、非破断接続片の一方は、スカート壁の下端縁に接続された上端部、上端部に続いて下方に向かって傾斜して或いは実質上水平に周方向片側に延びる第一の傾動部、薄肉中間部を介して第一の傾動部に接続され、下方に向かって傾斜して或いは実質上水平に周方向他側に延びる第二の傾動部、第二の傾動部を該タンパーエビデント裾部の上端縁に接続する下端部を有し、非破断接続片の他方は、スカート壁の下端縁に接続された上端部、上端部に続いて下方に向かって傾斜して或いは実質上水平に該周方向他側に延びる第一の傾動部、薄肉中間部を介して第一の傾動部に接続され、下方に向かって傾斜して或いは実質上水平に周方向片側に延びる第二の傾動部、第二の傾動部を該タンパーエビデント裾部の上端縁に接続する下端部を有する形態にせしめることを提案した。   Furthermore, the present inventors previously included, as an improvement of the above-mentioned synthetic resin container lid, in Japanese Patent Application No. 2008-178225, each of the non-breaking connecting pieces includes two inclined portions whose directions of inclination are opposite to each other. Proposed to form. More specifically, one of the non-breaking connecting pieces has an upper end connected to the lower end edge of the skirt wall, a first tilt extending obliquely downward following the upper end or substantially horizontally to one side in the circumferential direction. The second tilting portion and the second tilting portion which are connected to the first tilting portion via the thin-walled intermediate portion and tilted downward or substantially horizontally extending to the other side in the circumferential direction. It has a lower end connected to the upper end edge of the dent hem, and the other of the non-breaking connecting pieces is an upper end connected to the lower end edge of the skirt wall. A first tilting portion extending horizontally on the other side in the circumferential direction, a second tilting portion connected to the first tilting portion via a thin intermediate portion and tilting downward or substantially horizontally extending to one side in the circumferential direction The lower end connecting the tilting part and the second tilting part to the upper end edge of the tamper evidence hem part It proposed that allowed to the form with.

上記のとおりの形態の非破断接続片を含む合成樹脂製容器蓋においては、非破断接続片の各々は傾動方向が相互に逆である２個の傾斜部を含む形態である故に、単一の傾動部のみを含む場合と比べて、非破断接続片が存在する周方向寸法を増大せしめる必要なくしてタンパーエビデント裾部に対する本体の許容上昇距離が実質上２倍に増大せしめられ、口頸部から本体が離脱される際の本体の上昇距離が比較的長い場合にも適用することができる。しかしながら、本発明者等の経験によれば、かかる合成樹脂容器蓋も未だ充分に満足し得るものではなく、次のとおりの解決すべき問題が存在することが判明した。   In the synthetic resin container lid including the non-breaking connecting piece in the form as described above, each of the non-breaking connecting pieces includes two inclined portions whose tilt directions are opposite to each other. Compared to the case where only the tilting part is included, the allowable elevation distance of the main body with respect to the tamper evidence hem is substantially doubled without the need to increase the circumferential dimension in which the non-breaking connecting piece exists, and the mouth and neck The present invention can also be applied to a case where the ascending distance of the main body is relatively long when the main body is detached from the. However, according to the experience of the present inventors, it has been found that such a synthetic resin container lid is still not fully satisfactory, and the following problems to be solved exist.

第一に、消費者によっては、容器内の内容物を消費する際に、容器蓋本体をタンパーエビデント裾部から完全に分離して容器の口頸部から完全に離脱せしめることを望むこともある。この場合には非破断接続片の薄肉中間部に比較的大きな力を加えて薄肉中間部を破断し、かくして本体をタンパーエビデント裾部から完全に離脱し、容器の口頸部から完全に離脱する。この場合、強制的に破断された非破断接続片の下端部及び第二の傾動部はタンパーエビデント裾部と共に容器の口頸部に残留し、非破断接続片の下端部及び第二の傾動部はタンパーエビデント裾部の上端縁から上方に突出する。それ故に、容器の口頸部に口を付けて内容物を消費せんとすると、消費者の唇に非破断接続片の第二の傾動部が当接し、消費者に不快感を与えてしまう虞が少なくない。   First, some consumers may want the container lid body to be completely separated from the tamper-evidence hem and completely removed from the container's mouth and neck when consuming the contents in the container. is there. In this case, a relatively large force is applied to the thin middle part of the non-breaking connecting piece to break the thin middle part, thus completely detaching the main body from the tamper-evidence hem and completely detaching from the mouth and neck of the container. To do. In this case, the lower end portion and the second tilting portion of the non-breaking connecting piece that has been forcibly broken remain together with the tamper evidence skirt at the mouth and neck of the container, and the lower end portion and the second tilting portion of the non-breaking connecting piece. The portion protrudes upward from the upper end edge of the tamper evidence skirt. Therefore, if the contents are consumed by attaching the mouth to the mouth and neck of the container, the second tilting portion of the non-breaking connecting piece may come into contact with the lips of the consumer, which may cause discomfort to the consumer. There are many.

第二に、容器の口頸部を開封するために容器蓋の本体を容器の口頸部から離脱せしめる際には、タンパーエビデント裾部に対して本体を旋回せしめることが必要であるが、剛性が比較的小さい非破断接続片の第一の傾動部と第二の傾動部とを接続している薄肉中間部を旋回中心として本体が旋回せしめられるので、本体の旋回が必ずしも充分円滑に遂行し得ない虞が少なくない。   Second, when removing the container lid body from the container neck to open the container neck and neck, it is necessary to swivel the body against the tamper evidence hem, Since the main body can be swiveled around the thin middle part connecting the first and second tilting parts of the non-breaking connecting piece with relatively small rigidity, the swiveling of the main body is always performed sufficiently smoothly. There is a great possibility that it cannot be done.

本発明は上記事実に鑑みてなされたものであり、その主たる技術的課題は、消費者が非破断接続片を強制的に破断した場合に非破断接続片の実質上全体が本体と共にタンパーエビデント裾部から離脱され、従って上記第一の問題が発生することがなく、そして更にタンパーエビデント裾部に対して本体を旋回せしめる際には本体を充分円滑に旋回することができ、従って上記第二の問題もない、新規且つ改良された合成樹脂製容器蓋を提供することである。   The present invention has been made in view of the above-mentioned facts, and the main technical problem thereof is that when the consumer forcibly breaks the non-breaking connection piece, substantially the entire non-breaking connection piece is tampered with the main body. The detachment from the hem, and thus the first problem does not occur, and when the main body is further swiveled with respect to the tamper evidence hem, the main body can be swiveled sufficiently smoothly, and thus the first The object is to provide a new and improved synthetic resin container lid which does not have a second problem.

本発明者等は、鋭意検討の結果、非破断接続片の各々において中間部を薄肉にすることに代えて下端部を薄肉にすることによって、上記主たる技術的課題を達成することができることを見出した。   As a result of intensive studies, the present inventors have found that the main technical problem can be achieved by thinning the lower end portion instead of thinning the intermediate portion in each of the non-breaking connection pieces. It was.

即ち、本発明によれば、上記主たる技術的課題を達成する合成樹脂製容器蓋として、口頸部の外周面には雄螺条及び該雄螺条の下方に位置する係止あご部が形成されている容器に適用される合成樹脂製容器蓋であって、天面壁及び該天面壁の周縁から垂下する筒状スカート壁を有し、該スカート壁の内周面には該雄螺条に螺合せしめられる雌螺条が形成されている本体と、周方向に間隔をおいて配設された複数個の破断可能橋絡部を介して該本体の該スカート壁に接続され、内周面には該係止あご部に係止せしめられる係止手段が配設されている筒状タンパーエビデント裾部とを含み、該本体の該スカート壁には下方に突出する突出片が配設されており、該突出片の周方向両側には、該本体の該スカート壁と該タンパーエビデント裾部とを接続し且つ該タンパーエビデント裾部に対して該本体が上方に移動せしめられると鉛直線に対する傾斜角度が漸次減少せしめられる傾動部を有する非破断接続片が配設されている合成樹脂製容器蓋において、
該非破断接続片の一方は、該スカート壁の下端縁に接続された上端部、該上端部に続いて下方に向かって傾斜して或いは実質上水平に周方向片側に延びる第一の傾動部、中間部を介して該第一の傾動部に接続され、下方に向かって傾斜して或いは実質上水平に周方向他側に延びる第二の傾動部、該第二の傾動部を該タンパーエビデント裾部の上端縁に接続する薄肉下端部を有し、該非破断接続片の他方は、該スカート壁の下端縁に接続された上端部、該上端部に続いて下方に向かって傾斜して或いは実質上水平に該周方向他側に延びる第一の傾動部、中間部を介して該第一の傾動部に接続され、下方に向かって傾斜して或いは実質上水平に該周方向片側に延びる第二の傾動部、該第二の傾動部を該タンパーエビデント裾部の上端縁に接続する薄肉下端部を有する、ことを特徴とする合成樹脂製容器蓋が提供される。 That is, according to the present invention, as a synthetic resin container lid that achieves the main technical problem described above, a male thread and a locking jaw located below the male thread are formed on the outer peripheral surface of the mouth and neck. A synthetic resin container lid applied to a container that has a top surface wall and a cylindrical skirt wall that hangs down from the peripheral edge of the top surface wall. An inner peripheral surface connected to the skirt wall of the main body through a main body in which a female thread to be screwed is formed and a plurality of breakable bridging portions arranged at intervals in the circumferential direction Includes a cylindrical tamper-evidence hem portion on which locking means to be locked to the locking jaw is disposed, and a projecting piece projecting downward is disposed on the skirt wall of the main body. The skirt wall of the main body and the tamper evidence hem are connected to both sides in the circumferential direction of the protruding piece. And a synthetic resin container lid provided with a non-breaking connecting piece having a tilting portion whose tilt angle with respect to a vertical line is gradually decreased when the main body is moved upward with respect to the tamper evidence skirt. ,
One of the non-breaking connection pieces is an upper end connected to a lower end edge of the skirt wall, a first tilting portion that is inclined downward or substantially horizontally extending to one side in the circumferential direction following the upper end, A second tilting portion connected to the first tilting portion via an intermediate portion and tilting downward or extending substantially horizontally to the other side in the circumferential direction, the second tilting portion serving as the tamper evidence A thin lower end connected to the upper end edge of the skirt, and the other of the non-breaking connecting pieces is inclined at the upper end connected to the lower end edge of the skirt wall; A first tilting portion that extends substantially horizontally to the other side in the circumferential direction, is connected to the first tilting portion via an intermediate portion, and tilts downward or extends substantially horizontally to one side in the circumferential direction. Connect the second tilting portion and the second tilting portion to the upper edge of the tamper evidence skirt. Having a wall lower portion, the synthetic resin container closure is provided, characterized in that.

本発明の合成樹脂製容器蓋においては、消費者が非破断接続片を強制的に破断する場合には、非破断接続片とタンパーエビデント裾部との接続領域である、非破断接続片の薄肉下端部が破断され、従って非破断接続片の実質上全体が本体と共にタンパーエビデント裾部から離脱される。また、タンパーエビデント裾部に対して本体を旋回せしめる際には、非破断接続片と充分な剛性を有するタンパーエビデント裾部との境界領域である、非破断接続片の下端部が旋回中心として機能し、従って本体の旋回を充分円滑に遂行することができる。   In the synthetic resin container lid of the present invention, when the consumer forcibly breaks the non-breaking connection piece, the non-breaking connection piece is a connection region between the non-breaking connection piece and the tamper-evidence skirt. The thin lower end is broken, so that substantially the entire unbroken connection piece is detached from the tamper evidence skirt with the body. In addition, when the main body is swiveled with respect to the tamper evidence skirt, the lower end of the non-breaking connection piece, which is a boundary region between the non-breaking connection piece and the tamper evidence skirt having sufficient rigidity, is the turning center. Therefore, the turning of the main body can be performed sufficiently smoothly.

以下、本発明に従って構成された合成樹脂製容器蓋の好適実施形態を図示している添付図面を参照して、更に詳細に説明する。   Hereinafter, a preferred embodiment of a synthetic resin container lid constructed according to the present invention will be described in more detail with reference to the accompanying drawings.

本発明に従って構成された合成樹脂製容器蓋の好適実施形態を図示している図１及び図２を参照して説明すると、ポリエチレン又はポリプロピレンの如き適宜の合成樹脂から射出成形又は圧縮成形によって好都合に一体成形することができる、全体を番号２で示す容器蓋は、本体４とタンパーエビデント裾部６とを含んでいる。本体４は円形天面壁８とこの天面壁８の周縁から垂下する円筒形状のスカート壁１０とを有する。天面壁８の上面中央部には射出成形の際に突起が生成されるのを回避するための円形凹部１２が形成されている。天面壁８の内面には２条のシール突条、即ち内側環状突条１４及び外側環状突条１６が形成されている。スカート壁１０の外周面にはそこに掛けられる指の滑りを防止するための凹凸１８が繰り返し形成されている。スカート壁１０の内周面には雌螺条２０が形成されている。   Referring to FIGS. 1 and 2, which illustrate a preferred embodiment of a synthetic resin container lid constructed in accordance with the present invention, it can be conveniently produced by injection molding or compression molding from a suitable synthetic resin such as polyethylene or polypropylene. A container lid, generally designated 2, that can be integrally molded, includes a body 4 and a tamper evidence skirt 6. The main body 4 has a circular top wall 8 and a cylindrical skirt wall 10 depending from the periphery of the top wall 8. A circular recess 12 is formed at the center of the top surface of the top wall 8 to avoid the formation of protrusions during injection molding. Two seal ridges, that is, an inner annular ridge 14 and an outer annular ridge 16 are formed on the inner surface of the top wall 8. Concavities and convexities 18 are repeatedly formed on the outer peripheral surface of the skirt wall 10 to prevent the slipping of fingers hung thereon. A female thread 20 is formed on the inner peripheral surface of the skirt wall 10.

タンパーエビデント裾部６は全体として円筒形状であり、周方向に間隔をおいて配設された複数個の破断可能橋絡部２６（そのうちの１個を図２に図示している）を介して本体４のスカート壁１０に接続させている。破断可能橋絡部２６は特開２００７−１９１２０６号公報に開示されている破断可能橋絡部と実質上同一でよく、上端部はスカート壁１０の内周面下端部に接続され下端部はタンパーエビデント裾部６の内周面上端部に接続されている。タンパーエビデント裾部６の内周面には係止手段３４が配設されている。図示の実施形態における係止手段３４は、周方向に間隔をおいて配設された複数個の係止片（そのうちの１個を図２に図示ししている）から構成されており、係止片の各々はタンパーエビデント裾部６の内周面から半径方向内方に傾斜して上方に延出せしめられている。   The tamper evidence skirt 6 is generally cylindrical and includes a plurality of breakable bridging portions 26 (one of which is shown in FIG. 2) arranged at intervals in the circumferential direction. Are connected to the skirt wall 10 of the main body 4. The breakable bridge portion 26 may be substantially the same as the breakable bridge portion disclosed in Japanese Patent Application Laid-Open No. 2007-191206, the upper end portion is connected to the lower end portion of the inner peripheral surface of the skirt wall 10, and the lower end portion is a tamper. It is connected to the upper end of the inner peripheral surface of the evidence skirt 6. Locking means 34 is disposed on the inner peripheral surface of the tamper evidence skirt 6. The locking means 34 in the illustrated embodiment is composed of a plurality of locking pieces (one of which is shown in FIG. 2) arranged at intervals in the circumferential direction. Each of the stopper pieces is inclined inward in the radial direction from the inner peripheral surface of the tamper evidence skirt 6 and extended upward.

図示の容器蓋２における上述したとおりの構成は、本発明に従って構成された容器蓋２の新規な特徴を構成するものではなく、それ自体は周知の形態でよく、従ってこれらについての詳細な説明は本明細書においては省略する。   The configuration of the illustrated container lid 2 as described above does not constitute a novel feature of the container lid 2 constructed in accordance with the present invention and may itself be in a well-known form, so a detailed description thereof will not be given. It is omitted in this specification.

図１及び図２を参照して説明を続けると、番号４２で示す領域において、本体４のスカート壁１０の下端縁は他の領域の下端縁よりの上方に変位せしめられており、またタンパーエビデント裾部６の上端縁は他の領域の上端縁よりも下方に変位せしめられ、そして更に領域４２の中央部においてはタンパーエビデント裾部６の上端縁は更に幾分下方に変位せしめられており、スカート壁１０とタンパーエビデント裾部６との間には正面図において略横長矩形状の開口４４が生成されている。開口４４の周方向中央部において、スカート壁１０には下方に突出する略矩形状の突出片４６が形成されている。図３を参照することによって明確に理解される如く、突出片４６は実質上垂直に垂下し、次いで半径方向外方に若干変位した後に実質上鉛直に垂下しており、その外面には段部４７が形成されている。   1 and 2, the lower end edge of the skirt wall 10 of the main body 4 is displaced above the lower end edge of the other region in the region indicated by reference numeral 42. The upper edge of the dent skirt 6 is displaced below the upper edge of the other region, and the upper edge of the tamper evidence skirt 6 is further displaced downward in the center of the region 42. In the front view, an opening 44 having a substantially horizontally long rectangular shape is formed between the skirt wall 10 and the tamper evidence skirt 6. A substantially rectangular protruding piece 46 protruding downward is formed on the skirt wall 10 at the circumferential center of the opening 44. As can be clearly understood by referring to FIG. 3, the projecting piece 46 hangs substantially vertically and then hangs substantially vertically after being slightly displaced radially outward, and has a stepped portion on its outer surface. 47 is formed.

The non-breaking connection piece 50a in the illustrated embodiment has an upper end portion 52a connected to the lower end edge of the skirt wall 10, and then on the one side in the circumferential direction (right side in FIGS. 1 and 2) following the upper end portion 52a. The first tilting portion 54a extending substantially horizontally, the intermediate portion 56a extending slightly downward from the extending end portion of the first tilting portion 54a, and the other side in the circumferential direction facing the lower portion following the intermediate portion 56a (FIG. 1 and FIG. 2 (left side in FIG. 2) substantially horizontally and composed of a second tilting portion 58a and a lower end portion 60a that extends slightly downward from the extended end portion of the second tilting portion 58a and is connected to the tamper evidence skirt portion 6. Has been. The lower end portion 60a of the non-breaking connection piece 50a is thin, in other words, thicker than other portions, that is, the upper end portion 52a, the first tilting portion 54a, the intermediate portion 56a, and the second tilting portion 58a. It is important that this is reduced. The non-breaking connecting piece 50b is line symmetrical with the non-breaking connecting piece 50a, and has an upper end portion 52b connected to the lower end edge of the skirt wall 10, and the other end in the circumferential direction downward (see FIG. 1). And the left side in FIG. 2) the first tilting portion 54b extending substantially horizontally, the intermediate portion 56b extending slightly downward from the extending end of the first tilting portion 54b, and the periphery facing downward following the intermediate portion 56b. The second tilting portion 58b extending substantially horizontally on one side of the direction (right side in FIGS. 1 and 2) and the extending end portion of the second tilting portion 58b extend slightly downward and are connected to the tamper evidence skirt portion 6. It is comprised from the lower end part 60b. The lower end portion 60b of the non-breaking connecting piece 50b is thin, in other words, thicker than other portions, that is, the upper end portion 52b, the first tilting portion 54b, the intermediate portion 56b, and the second tilting portion 58b. It is important that this is reduced.

The thickness of the lower end portions 60a and 60b of the non-breaking connection pieces 50a and 50b may be about 0.2 to 0.4 mm. If desired, the first tilting part 54a and the second tilting part 58a in the non-breaking connection piece 50a and the first tilting part 54b and the second tilting part 58b in the non-breaking connection piece 50b are not horizontal but downward. It can also be made to extend somewhat inclined.

図２を参照して説明を続けると、ポリエチレンテレフタレートの如き適宜の合成樹脂或いはガラスから形成することができる容器の口頸部６４は全体として円筒形状であり、その上面は開口されている。口頸部６４の外周面には、雄螺条６６とこの雄螺条６６の下方に位置する係止あご部６８が形成されている。図５及び図６に図示する如く、雄螺条６６には周方向に間隔おいて通気用切欠６７が形成されている。   Continuing the description with reference to FIG. 2, the mouth-and-neck portion 64 of the container, which can be formed from an appropriate synthetic resin such as polyethylene terephthalate or glass, has a cylindrical shape as a whole, and its upper surface is opened. A male thread 66 and a locking jaw 68 positioned below the male thread 66 are formed on the outer peripheral surface of the mouth and neck portion 64. As shown in FIGS. 5 and 6, the male thread 66 is formed with ventilation notches 67 at intervals in the circumferential direction.

口頸部６４に容器蓋２を装着して口頸部６４を密封する際には、口頸部６４に容器蓋２を被嵌して閉方向（図２において上方から見て時計方向）に回転せしめ、口頸部６４の雄螺条６６に容器蓋２の雌螺条２０を螺合せしめる。雄螺条６６に対する雌螺条２０の螺合の進行に応じて容器蓋２は口頸部６４に対して漸次下降する。図２に図示する状態まで口頸部６４に対して容器蓋２が下降せしめられると、容器蓋２の本体４における天面壁８の内面に形成されている内側環状突条１４及び外側環状突条１６が夫々口頸部６４の内周面及び外周面に密接せしめられ、これによって口頸部６４が密封される。容器蓋２のタンパーエビデント裾部６の内周面に配設されている係止手段３４は口頸部６４の係止あご部６８を弾性的に乗り越えて、係止あご部６８の下面に係止せしめられる。   When the container lid 2 is attached to the mouth-and-neck portion 64 and the mouth-and-neck portion 64 is sealed, the container lid 2 is fitted on the mouth-and-neck portion 64 and closed (clockwise as viewed from above in FIG. 2). The female thread 20 of the container lid 2 is screwed together with the male thread 66 of the mouth-and-neck part 64 by rotating. As the female thread 20 is engaged with the male thread 66, the container lid 2 gradually descends with respect to the mouth-and-neck portion 64. When the container lid 2 is lowered with respect to the mouth-and-neck portion 64 to the state shown in FIG. 2, the inner annular ridge 14 and the outer annular ridge formed on the inner surface of the top wall 8 in the main body 4 of the container lid 2. 16 are respectively brought into close contact with the inner peripheral surface and the outer peripheral surface of the mouth-and-neck portion 64, whereby the mouth-and-neck portion 64 is sealed. The locking means 34 disposed on the inner peripheral surface of the tamper evidence skirt 6 of the container lid 2 elastically climbs over the locking jaw 68 of the mouth-and-neck 64 and is placed on the lower surface of the locking jaw 68. It can be locked.

口頸部６４を開封する際には、容器蓋２を開方向（図２において上方から見て反時計方向）に回転せしめ、口頸部６４の雄螺条６６に対する容器蓋２の雌螺条２０の螺合を漸次解除する。螺合を漸次解除すると容器蓋２の本体４は開方向に回転せしめられると共に上昇せしめられるが、タンパーエビデント裾部６は係止手段３４が口頸部６４の係止あご部６８に係止しているので上昇が阻止され、これに起因して破断可能橋絡部２６に相当な応力が生成され、破断可能橋絡部２６が破断される。しかる後においては、容器蓋２の本体２は開方向への回転と共に上昇し、タンパーエビデント裾部６から上方に漸次離間せしめられる。図２と共に図４を参照することによって明確に理解される如く、タンパーエビデント裾部６から本体４が漸次上方に離間せしめられると、非破断接続片５０ａの第一の傾動片５４ａ及び非破断接続片５０ｂの第二の傾動部５８ｂは夫々の上端及び下端を中心として図２及び図４において時計方向に旋回、即ち時計方向に傾動され、一方非破断接続片５０ａの第二の傾動片５８ａ及び非破断接続片５０ｂの第一の傾動部５４ｂは夫々の下端及び上端を中心として図２及び図４において反時計方向に旋回、即ち反時計方向に傾動され、これに応じて非破断接続片５０ａ及び５０ｂにおける第一の傾動部５４ａ及び５４ｂ並びに第二の傾動部５８ａ及び５８ｂの鉛直線に対する傾斜角度αが漸次低減される。図２及び図４と共に図５を参照することによって明確に理解される如く、口頸部６４の雄螺条６６に対する容器蓋２の雌螺条２０の螺合が完全に解除されると、容器蓋２の本体４は口頸部６４から離脱される。しかしながら、本体４は非破断接続片５０ａ及び５０ｂを介して、口頸部６４に装着され続けているタンパーエビデント裾部６に接続され続けている故に、容器の口頸部６４から離間されることはない。   When opening the mouth and neck portion 64, the container lid 2 is rotated in the opening direction (counterclockwise as viewed from above in FIG. 2), and the female thread of the container lid 2 with respect to the male thread 66 of the mouth and neck portion 64 is rotated. The 20 screwing is gradually released. When the screwing is gradually released, the main body 4 of the container lid 2 is rotated and lifted in the opening direction, but the tamper evidence skirt 6 is locked by the locking means 34 to the locking jaw 68 of the mouth and neck 64. As a result, the rise is prevented, and due to this, a considerable stress is generated in the breakable bridge 26 and the breakable bridge 26 is broken. After that, the main body 2 of the container lid 2 rises with the rotation in the opening direction, and is gradually separated upward from the tamper evidence skirt 6. As clearly understood by referring to FIG. 4 in conjunction with FIG. 2, when the body 4 is gradually spaced upward from the tamper evidence skirt 6, the first tilting piece 54a of the non-breaking connecting piece 50a and the non-breaking The second tilting portion 58b of the connecting piece 50b is pivoted clockwise in FIGS. 2 and 4 around the respective upper and lower ends, that is, tilted clockwise, while the second tilting piece 58a of the non-breaking connecting piece 50a. The first tilting portion 54b of the non-breaking connecting piece 50b is pivoted counterclockwise in FIGS. 2 and 4 around the lower end and the upper end of the non-breaking connecting piece 50b, that is, tilted counterclockwise. The inclination angle α of the first tilting parts 54a and 54b and the second tilting parts 58a and 58b at 50a and 50b with respect to the vertical line is gradually reduced. As clearly understood by referring to FIG. 5 together with FIGS. 2 and 4, when the female thread 20 of the container lid 2 is completely disengaged from the male thread 66 of the mouth and neck 64, the container The main body 4 of the lid 2 is detached from the mouth / neck portion 64. However, the main body 4 is separated from the container's mouth and neck 64 because it continues to be connected to the tamper evidence skirt 6 that is still attached to the mouth and neck 64 via the non-breaking connection pieces 50a and 50b. There is nothing.

本発明に従って構成された容器蓋２においては、非破断接続片５０ａ及び５０ｂは傾動方向が相互に逆である２個の傾動部即ち第一の傾動部５４ａ及び第二の傾動部５８ａ並びに第一の傾動部５４ｂ及び第二の傾動部５８ｂを含んでいる故に、非破断接続片５０ａ及び５０ｂが存在する周方向寸法は比較的小さいにも拘らず、タンパーエビデント裾部６に対して本体２が相当な長さに亘って上方に離間することを許容する。従って、口頸部６４から本体２を離脱するためには本体２を相当な長さに亘って本体２を上昇せしめる必要がある場合にも、特に問題を発生せしめることなく本体２を口頸部６４から離脱することができる。   In the container lid 2 constructed in accordance with the present invention, the non-breaking connecting pieces 50a and 50b have two tilting portions whose tilt directions are opposite to each other, that is, the first tilting portion 54a and the second tilting portion 58a and the first tilting portion. 2 and the second tilting portion 58b, the main body 2 with respect to the tamper evidence skirt 6 is provided in spite of the relatively small circumferential dimension of the non-breaking connecting pieces 50a and 50b. Is allowed to be spaced upwards over a substantial length. Therefore, even when the main body 2 needs to be lifted over a considerable length in order to detach the main body 2 from the mouth / neck portion 64, the main body 2 can be moved to the mouth / neck portion without causing any particular problem. 64 can be disengaged.

容器蓋２の本体４が口頸部６４から離脱された後においては、非破断接続片５０ａ及び５０ｂの薄肉下端部６０ａ及び６０ｂをヒンジ支点として本体４を口頸部６４から遠ざかる方向に、図５に図示する状態まで旋回せしめる。かくすると、本体４に形成されている突出片４６の下端部（先端部）外側面が口頸部の係止あご部６８の上面に当接し、突出片４６の外面に形成されている段部４７が係止あご部６８の上面に係止せしめられる共に、本体４のスカート壁１０の下端がタンパーエビデント裾部６の外周面に当接し、これによって本体４は図５に図示する位置に解除自在に保持される。従って、消費者は本体４の存在によって阻害されることなく、容器内に存在する清涼飲料の如き内容物を飲食することができる。薄肉下端部６０ａ及び６０ｂは非破断接続片５０ａ及び５０ｂと充分な剛性を有するタンパーエビデント裾部６との境界領域であるので、上述したとおりの本体４の旋回は充分円滑に遂行することができる。   After the main body 4 of the container lid 2 is detached from the mouth-and-neck portion 64, the main body 4 is moved away from the mouth-and-neck portion 64 with the thin lower end portions 60 a and 60 b of the non-breaking connection pieces 50 a and 50 b as hinge fulcrums. Turn to the state shown in FIG. In this way, the outer surface of the lower end (front end) of the protruding piece 46 formed on the main body 4 abuts on the upper surface of the locking jaw 68 of the mouth-and-neck portion, and the step formed on the outer surface of the protruding piece 46. 47 is locked to the upper surface of the locking jaw portion 68, and the lower end of the skirt wall 10 of the main body 4 abuts against the outer peripheral surface of the tamper evidence skirt portion 6, so that the main body 4 is in the position shown in FIG. It is held releasably. Therefore, the consumer can eat and drink contents such as a soft drink present in the container without being obstructed by the presence of the main body 4. Since the thin lower end portions 60a and 60b are boundary regions between the non-breaking connection pieces 50a and 50b and the tamper evidence skirt 6 having sufficient rigidity, the turning of the main body 4 as described above can be performed sufficiently smoothly. it can.

内容物の飲食を途中で中断した場合には、図５に図示する位置に保持されている本体４を口頸部６４に接近する方向に旋回せしめて再び口頸部６４に被嵌し、そして容器蓋２を閉方向に回転せしめて口頸部６４の雄螺条６６に容器蓋２の雌螺条２０を螺合せしめ、かくして容器蓋２を再び図２に図示する状態に位置せしめ、口頸部６４を仮密封することができる。   When the eating and drinking of the contents is interrupted halfway, the main body 4 held at the position shown in FIG. 5 is turned in the direction approaching the mouth and neck portion 64 and is fitted on the mouth and neck portion 64 again. The container lid 2 is rotated in the closing direction so that the female thread 20 of the container lid 2 is screwed into the male thread 66 of the mouth-and-neck portion 64, and thus the container lid 2 is positioned again in the state shown in FIG. The neck 64 can be temporarily sealed.

一方、消費者が容器蓋２の本体４を口頸部６４から完全に分離せしめることを望む場合には、本体４を把持して所要方向に引っ張って非破断接続片５０ａ及び５０ｂにおける薄肉下端部６０ａ及び６０ｂに応力を加えて薄肉下端部６０ａ及び６０ｂを強制的に破断し、図６に図示する如く本体４をタンパーエビデント裾部６から分離して口頸部６２から完全に分離せしめることができる。薄肉下端部６０ａ及び６０ｂが破断されて本体４がタンパーエビデント裾部６から分離される故に、口頸部６２に非破断接続片５０ａ及び５０ｂが部分的に残留せしめられて、消費者の唇に非破断接続片５０ａ及び５０ｂの残留部が当接して消費者に不快感を与えてしまうことが確実に回避される。   On the other hand, when the consumer desires to completely separate the main body 4 of the container lid 2 from the mouth-and-neck part 64, the thin bottom end of the non-breaking connection pieces 50a and 50b is grasped and pulled in the required direction. Stress is applied to 60a and 60b to forcibly break the thin lower end portions 60a and 60b, and as shown in FIG. 6, the main body 4 is separated from the tamper-evidence skirt portion 6 and completely separated from the mouth and neck portion 62. Can do. Since the thin lower end portions 60a and 60b are broken and the main body 4 is separated from the tamper evidence skirt portion 6, the non-breaking connection pieces 50a and 50b are partially left on the mouth and neck portion 62, and the lips of the consumer It is reliably avoided that the remaining portions of the non-breaking connection pieces 50a and 50b come into contact with each other and give the consumer unpleasant feeling.
