Next, when the container is tilted, the content flows out through the passage opening formed in the closed wall 8 of the inner plug 4 and the discharge opening 24 formed in the cover wall 20 of the lid body 6 and is guided to the discharge guide wall 26. Is discharged.

本発明に従って構成された容器蓋２においては、中栓４に対して蓋本体６を図１及び図２において上方から見て反時計方向に回転せしめると、中栓４の装着壁１０の外周面に接続されたタンパーエビデント片３８に対して外蓋１８のスカート壁３２の外周面に接続されたタンパーエビデント片３８の他端が漸次離隔せしめられ、図８に示すとおり、タンパーエビデント片３８の破断可能弱化部４２に集中応力が作用して破断可能弱化部４２が破断されてタンパーエビデント片３８が２個の部分に分離される。タンパーエビデント片３８の破断可能弱化部４２の破断は、中栓４の閉塞壁８に形成されている破断可能薄肉ライン１１の破断が開始される前、例えば中栓４に対して蓋本体６が５０乃至６０度程度回転される前に実現せしめられるのが好都合である。かような次第であるので、本発明に従って構成された容器蓋２においては、悪戯によって中栓４に対して蓋本体６が所要角度以上回転せしめられると、タンパーエビデント片３８が２個の部分に分離され、これによって悪戯の痕跡が残留せしめられる。 In the container lid 2 configured according to the present invention, when the lid body 6 is rotated counterclockwise as viewed from above in FIGS. 1 and 2 with respect to the inner plug 4, the outer peripheral surface of the mounting wall 10 of the inner plug 4 The tamper-evidence piece 38 connected to the outer peripheral surface of the skirt wall 32 of the outer lid 18 is gradually separated from the tamper-evidence piece 38 connected to the tamper-evident piece 38, and as shown in FIG. The concentrated stress acts on the breakable weakening portion 42 of 38, the breakable weakening portion 42 is broken, and the tamper evidence piece 38 is separated into two parts. The breakable weakening portion 42 of the tamper evidence piece 38 is broken before the breakable thin line 11 formed on the closing wall 8 of the inner plug 4 starts to break, for example, the lid body 6 with respect to the inner plug 4. It is expedient to achieve this before it is rotated by 50 to 60 degrees. Therefore, in the container lid 2 configured in accordance with the present invention, if the lid body 6 is rotated more than the required angle with respect to the inner plug 4 by mischief, the tamper evidence piece 38 has two parts. This leaves a trace of mischief.

本発明に従って構成された容器蓋２においては、更に、中栓４に対して蓋本体６が反時計方向に回転せしめられるのに先立って、悪戯によって蓋本体６の外蓋１８が、図１及び図２に実線で示し図７に二点鎖線で示す閉位置から図９に実線で示す開位置に旋回せしめられた場合にも、中栓４の装着壁１０の外周面に接続されたタンパーエビデント片３８に対して外蓋１８のスカート壁３２の外周面に接続されたタンパーエビデント片３８の他端が漸次離隔せしめられ、図９に示すとおり、タンパーエビデント片３８の破断可能弱化部４２に集中応力が作用して破断可能弱化部４２が破断されてタンパーエビデント片３８が２個の部分に分離され、かくして悪戯の痕跡が残留せしめられる。 In the container lid 2 constructed in accordance with the present invention, the outer lid 18 of the lid body 6 is further misunderstood before the lid body 6 is rotated counterclockwise with respect to the inner stopper 4 as shown in FIGS. The tamper shrimp connected to the outer peripheral surface of the mounting wall 10 of the inner plug 4 even when it is swung from the closed position shown by the solid line in FIG. 2 to the open position shown by the solid line in FIG. The other end of the tamper evidence piece 38 connected to the outer peripheral surface of the skirt wall 32 of the outer lid 18 is gradually separated from the dent piece 38, and the breakable weakened portion of the tamper evidence piece 38 is shown in FIG. Concentrated stress acts on 42, the breakable weakening portion 42 is broken, and the tamper evidence piece 38 is separated into two parts, thus leaving a trace of mischief.

以上、添付図面を参照して本発明に従って構成された容器蓋の好適実施形態について詳細に説明したが、本発明はかかる実施形態に限定されるものではなく、本発明の範囲を逸脱することなく種々の変形乃至修正が可能であることは多言を要しない。 The preferred embodiments of the container lid constructed according to the present invention have been described in detail with reference to the accompanying drawings. However, the present invention is not limited to such embodiments and does not depart from the scope of the present invention. It is not necessary to say variously that various modifications or corrections are possible.

例えば、図示の実施形態においては、タンパーエビデント片３８の一端を中栓４の装着壁１０の外周面に一体に接続し、他端を係合手段４０及び被係合手段４４を介して外蓋１８のスカート壁３２の外周面に接続しているが、所望ならば、タンパーエビデント片の他端を外蓋のスカート壁の外周面に一体に接続し、一端を適宜の係合手段及び被係合手段を介して中栓の装着壁の外周面に接続することもできる。また、タンパーエビデント片の他端又は一端を係合手段及び被係合手段を介して外蓋のスカート壁の外周面又は中栓の装着壁の外周面に溶着することもできる。更に、所望ならば、中栓及び蓋本体と別個に成形したタンパーエビデント片の両端を中栓の装着壁の外周面及び外蓋のスカート壁の外周面に溶着することもできる。 For example, in the illustrated embodiment, one end of the tamper evidence piece 38 is integrally connected to the outer peripheral surface of the mounting wall 10 of the inner plug 4, and the other end is externally connected via the engaging means 40 and the engaged means 44. Although connected to the outer peripheral surface of the skirt wall 32 of the lid 18, if desired, the other end of the tamper evidence piece is integrally connected to the outer peripheral surface of the skirt wall of the outer lid, and one end is connected to an appropriate engagement means and It can also be connected to the outer peripheral surface of the mounting wall of the inner plug through the engaged means. Further, the other end or one end of the tamper-evident piece can be welded to the outer peripheral surface of the skirt wall of the outer lid or the outer peripheral surface of the mounting wall of the inner plug through the engaging means and the engaged means. Furthermore, if desired, both ends of the tamper evidence piece formed separately from the inner plug and the lid main body can be welded to the outer peripheral surface of the inner plug mounting wall and the outer peripheral surface of the outer lid skirt wall.

更に、図示の実施形態においては、中栓４の閉塞壁８に配設された破断可能薄肉ライン１１が破断され変形領域１２が変形されることによって閉塞壁８に通過開口が生成されるが、所望ならば上記特許文献１に開示されている如く、中栓の閉塞壁に配設されている破断可能薄肉ラインが破断されて破断領域が閉塞壁から分離され、かくして通過開口が生成されるように構成することもできる。 Further, in the illustrated embodiment, the breakable thin line 11 disposed on the closing wall 8 of the inner plug 4 is broken and the deformation region 12 is deformed to generate a passage opening in the closing wall 8. If desired, as disclosed in the above-mentioned Patent Document 1, the breakable thin line disposed on the closing wall of the inner plug is broken to separate the breaking region from the closing wall, thus creating a passage opening. It can also be configured.
