Description

好ましくは、該中栓の該閉塞壁の下面には、該破断可能薄肉ラインの半径方向内側において該閉塞壁の下面に接続された基端から半径方向外方に向かって下方に傾斜して延出し、延出端は半径方向において該破断可能薄肉ラインよりも外方に位置する環状シール片が形成されており、該外蓋が該中栓又は該口頸部から離脱される際には該シール片は弾性的に撓んで該その他の部分より上方に移動し、該外蓋が該中栓又は該口頸部に再装着される際には該シール片が該閉塞壁の該その他の部分の上面に当接して該除去領域の下方への移動が阻止される。好適には、該被係止突条及び該係止突条を介して伝えられる力によって該破断可能薄肉ラインは破断する。該被係止壁部には被係合手段が配設され、該係止片には係合手段が配設され、該被係合手段及び該係合手段を介して伝えられる力によって該破断可能薄肉ラインは破断してもよい。該外蓋の該天面壁の下面或いは該係止片又は該中栓の該被係止壁部の上面には、該外蓋が該中栓又は該口頸部に再装着される際に該被係止壁部又は該天面壁に当接して該外蓋に対する該除去領域の上昇を阻止する阻止片が形成されているのが好適である。該外蓋の該天面壁の下面又は該係止片には、該外蓋が該中栓又は該口頸部に再装着される際に該被係止壁部に当接して該外蓋に対する該除去領域の上昇を阻止する阻止片が形成されているのが好適である。該中栓の該被係止壁部の上面には、該外蓋が該中栓又は該口頸部に再装着される際に該外蓋の該天面壁の下面に当接して該外蓋に対する該除去領域の上昇を阻止する阻止片が形成されていてもよい。 Preferably, the bottom surface of the closing wall of the inner plug is inclined downward and radially outward from the proximal end connected to the lower surface of the blocking wall on the radially inner side of the breakable thin line. An annular seal piece is formed in the radial direction at the outer end of the thin line that can be broken, and when the outer lid is removed from the inner plug or the mouth and neck, The sealing piece elastically bends and moves above the other part, and when the outer lid is reattached to the inner plug or the mouth and neck, the sealing piece becomes the other part of the blocking wall. The removal region is prevented from moving downward by contacting the upper surface of the surface. Preferably, the breakable thin line is broken by the locked protrusion and the force transmitted through the locking protrusion. The to said engaging wall portion engaged means is disposed, the engaging means is disposed on the engaging piece,該破cross by forces transmitted through the該被engaging means and said engaging means The possible thin line may be broken. When the outer lid is remounted on the inner plug or the neck of the mouth, the lower surface of the top wall of the outer lid or the upper surface of the locking piece or the locked wall portion of the inner plug It is preferable that a blocking piece that is in contact with the locked wall portion or the top surface wall to prevent the removal region from rising relative to the outer lid is preferably formed. The lower surface of the top wall of the outer lid or the locking piece comes into contact with the locked wall portion when the outer lid is reattached to the inner plug or the mouth-neck portion. It is preferable that a blocking piece for preventing the removal region from rising is formed. The outer lid is brought into contact with the lower surface of the top wall of the outer lid when the outer lid is remounted on the inner stopper or the mouth-and-neck portion of the inner wall of the inner stopper. A blocking piece may be formed to prevent the removal region from rising relative to the surface.

Claims

The to said locking walls engageable means is disposed, the engaging means is disposed on the engaging piece,
The container lid according to any one of claims 1 to 3, wherein the breakable thin line is broken by the force transmitted through the engaged means and the engaging means.
