A small discharge opening is created in the shielding wall, and the outer lid is connected to the top wall and the periphery of the top wall. There is provided a container lid characterized in that it includes a cylindrical skirt wall depending from and which is pivotally connected to the intermediate lid via the second hinge means.

好ましくは、該小量排出部材の該遮蔽壁には少なくとも１個のスリットが配設されている。該小量排出部材の該遮蔽壁は凹状であり、容器内圧が上昇せしめられると突状に変形され該スリットが拡張されて該小量排出開口が生成されるのが好適である。該スリットは十字形状であるのが好ましい。好適には、該外蓋の該天面壁は、該外蓋が該閉位置に位置せしめられると該小量排出部材の該遮蔽壁の上面の少なくとも一部に密接せしめられる密封部を有する該外蓋の該天面壁は、該外蓋が該閉位置に位置せしめられると該中間蓋の該上面壁に密接せしめられて該装着開口を密封するシール片を有するのが好適である。該第一のヒンジ手段と該第二のヒンジ手段とは６０乃至１５０度の角度間隔をおいて配置されているのがよい。好ましくは、該蓋本体の該筒状側壁の内周面には被係止突条が形成されており、該容器の該口頸部に該蓋本体を被嵌し該蓋本体を下方に強制して、該蓋本体の該被係止突条を該容器の該口頸部の外周面上部に形成されている係止突条に係止せしめることによって、該容器の該口頸部に該蓋本体が装着される。 Preferably, at least one slit is disposed on the shield wall of the small amount discharge member. It is preferable that the shielding wall of the small amount discharge member is concave, and when the internal pressure of the container is increased, the small amount discharge member is deformed into a projecting shape and the slit is expanded to generate the small amount discharge opening. The slit is preferably cross-shaped. Preferably, the top wall of the outer lid has a sealing portion that is in close contact with at least a portion of the upper surface of the shielding wall of the small volume discharge member when the outer lid is positioned in the closed position. The top wall of the lid preferably has a sealing piece that is brought into close contact with the top wall of the intermediate lid and seals the mounting opening when the outer lid is positioned in the closed position.

外蓋８が図１、図４及び図５に図示する閉位置に位置せしめられている時には、外蓋８のスカート壁５４の下端部に接続部５７が形成されていない領域において係止溝６０が中間蓋６の係止突条３６に係止せしめられ、これによって外蓋８が閉位置に維持される。一方、外蓋８のスカート壁５４の下端部に接続部６０が形成されている領域においては接続部５７の平坦部５７ａの半径方向内側端部の内側面が中間蓋６の係止突条３６の上端に当接せしめられる。更に、外蓋８が中間蓋６に対して閉位置に位置せしめられた状態においては、天面壁５２に形成された密封部６２が装着開口３８に装着された小量排出部材４２の遮蔽壁４４の上面中央部、より詳細には遮蔽壁４４上にスリット４６が形成された領域を含む領域、に密接せしめられる。これにより、外蓋８と共に中間蓋６が閉位置に位置せしめられているときに容器内圧が上昇せしめられた場合であっても遮蔽壁４４が突状に変形されスリット４６が拡張されて小量排出開口が生成され内容物がこの小量排出開口から排出されることが防止される。外蓋８が中間蓋６に対して閉位置に位置せしめられた状態においては更に、天面壁５２に形成されたシール片６４の内周面が突出筒４０の上部４０ｃの外周面と密接せしめられる（所望ならば、シール片６４の外周面を突出筒４０の上部４０ｃの内周面と密接せしめられるようにシール片６４を位置せしめてもよい）。これにより、上記した小量排出開口からの内容物の排出がより確実に防止されることとなる。   When the outer lid 8 is positioned at the closed position shown in FIGS. 1, 4, and 5, the locking groove 60 is formed in a region where the connecting portion 57 is not formed at the lower end portion of the skirt wall 54 of the outer lid 8. Is locked to the locking protrusion 36 of the intermediate lid 6, whereby the outer lid 8 is maintained in the closed position. On the other hand, in the region where the connecting portion 60 is formed at the lower end of the skirt wall 54 of the outer lid 8, the inner side surface of the radially inner end of the flat portion 57 a of the connecting portion 57 is the locking protrusion 36 of the intermediate lid 6. It is made to contact | abut to the upper end of. Further, in a state where the outer lid 8 is positioned at the closed position with respect to the intermediate lid 6, the shielding wall 44 of the small amount discharge member 42 in which the sealing portion 62 formed on the top wall 52 is attached to the attachment opening 38. And the region including the region where the slit 46 is formed on the shielding wall 44 in more detail. As a result, even when the inner pressure of the container is raised when the intermediate lid 6 is positioned in the closed position together with the outer lid 8, the shielding wall 44 is deformed in a projecting shape and the slit 46 is expanded to reduce the amount of the small amount. A discharge opening is created and the contents are prevented from being discharged from this small discharge opening. In the state where the outer lid 8 is positioned at the closed position with respect to the intermediate lid 6, the inner circumferential surface of the seal piece 64 formed on the top wall 52 is further brought into close contact with the outer circumferential surface of the upper portion 40 c of the protruding cylinder 40. (If desired, the seal piece 64 may be positioned so that the outer peripheral surface of the seal piece 64 is brought into close contact with the inner peripheral surface of the upper portion 40c of the protruding cylinder 40). Thereby, discharge of the contents from the above-described small amount discharge opening is more reliably prevented.

蓋本体４に中間蓋６を旋回自在に接続しているヒンジ手段５０と中間蓋６に外蓋８を旋回自在に接続しているヒンジ手段５６とは６０乃至１５０度の角度間隔をおいて配設されているのが好都合である。図示の実施形態においては、図２及び図３を参照することによって明確に理解される如く、蓋本体４に中間蓋６を旋回自在に接続しているヒンジ手段５０と中間蓋６に外蓋８を旋回自在に接続しているヒンジ手段５６とは９０度の角度間隔をおいて配設されている。   The hinge means 50 for pivotally connecting the intermediate lid 6 to the lid body 4 and the hinge means 56 for pivotally connecting the outer lid 8 to the intermediate lid 6 are arranged at an angular interval of 60 to 150 degrees. Conveniently installed. In the illustrated embodiment, as clearly understood by referring to FIGS. 2 and 3, the hinge means 50 pivotably connects the intermediate lid 6 to the lid body 4 and the outer lid 8 to the intermediate lid 6. Are disposed at an angular interval of 90 degrees.

図１、図４乃至図７には、本発明に従って構成された容器蓋２と共に、容器蓋２が適用される容器の口頸部６６も図示されている。ポリエチレンテレフタレートの如き適宜の合成樹脂から形成することができる容器は全体として円筒形状の口頸部６６を有し、かかる口頸部６６の外周面上端部には環状被係止突条６８が形成されている。口頸部６６の外周面には、更に、被係止突条６８の下方に位置するサポートリング７０も形成されている。   FIGS. 1 and 4 to 7 also show the container neck 2 of the container to which the container lid 2 is applied together with the container lid 2 configured according to the present invention. A container that can be formed from an appropriate synthetic resin such as polyethylene terephthalate has a cylindrical mouth / neck portion 66 as a whole, and an annular locking protrusion 68 is formed at the upper end of the outer peripheral surface of the mouth / neck portion 66. Has been. A support ring 70 positioned below the locked protrusion 68 is also formed on the outer peripheral surface of the mouth and neck portion 66.

例えば液体調味料である内容物を容器内に充填した後に口頸部６６に容器蓋２を装着して口頸部６６を密封する際には、中間蓋６と外蓋８とが共に閉位置に位置せしめられている容器蓋２を口頸部６６に被嵌し、次いで口頸部６６に対して容器蓋２を下方に強制する。かくして、図４及び図５に明確に図示する如く、蓋本体４のシール片２４を容器の内周面に密接せしめるとともに、蓋本体４の側壁１２の内周面に形成されている係止突条２６が口頸部６６の外周面に形成されている被係止突条６８を弾性的に乗り越えてその下方に係止するようにせしめる。   For example, when the container lid 2 is attached to the mouth / neck portion 66 after the contents of liquid seasoning are filled in the container and the mouth / neck portion 66 is sealed, the intermediate lid 6 and the outer lid 8 are both closed. The container lid 2 positioned on the mouth and neck portion 66 is fitted, and then the container lid 2 is forced downward with respect to the mouth and neck portion 66. Thus, as clearly shown in FIGS. 4 and 5, the sealing piece 24 of the lid main body 4 is brought into close contact with the inner peripheral surface of the container, and the locking protrusion formed on the inner peripheral surface of the side wall 12 of the lid main body 4. The strip 26 elastically climbs over the locked protrusion 68 formed on the outer peripheral surface of the mouth-and-neck portion 66 so as to be locked below it.

容器内に収容されている内容物を消費する際には、最初に、閉位置に位置せしめられている外蓋８と共に中間蓋６を図１、図４及び図５に図示する閉位置から図７に図示する開位置に旋回動せしめ、蓋本体４の閉塞壁１０を露呈せしめる。次いで、引張手段２２に指を掛けて上方に引っ張って破断可能ライン２０を破断せしめて、除去領域１８を閉塞壁１０から除去して閉塞壁１０に比較的大きい大量排出開口を生成し、しかる後に外蓋８と共に中間蓋６を閉位置に戻す。
容器内に収容されている内容物を小量排出する場合には、外蓋８を図１、図４及び図５に図示する閉位置から図６に図示する開位置に旋回して小量排出開口が形成される遮蔽壁４４を露呈せしめ、次いで容器を倒立状態にし容器の胴部を圧縮する。かくすると、容器内圧が上昇せしめられ、遮蔽壁４４が図６に二点鎖線で示す如く上方に突状に変形されて十字状スリット４６が図２及び図３に二点鎖線で示すように拡張され小量排出開口が形成され、かかる小量排出開口から内容物が小量排出される。所望量の内容物を排出した後には、容器の胴部の圧縮を解除して容器内圧を大気圧に戻すことで遮蔽壁４４は元の凹状に戻りスリット４６の拡張が解除されてスリット４６が閉じられる。これにより、内容物の小量排出が停止すると共に液だれが防止される。外蓋８を閉位置に戻すと、外蓋８の密封部６２が遮蔽壁４４の上面に密接せしめられ、かくして小量排出開口が形成されるスリット４６が充分確実に密封される。
容器に収容されている内容物を大量排出する場合には、閉位置に位置せしめられている外蓋８と共に中間蓋６を図１、図４及び図５に図示する閉位置から図７に図示する開位置に旋回して、蓋本体４の閉塞壁１０を露呈せしめる。次いで、容器を傾動せしめると大量排出開口を通して内容物を大量排出することができる。生成された大量排出開口を通して内容物が大量排出される際には排出案内筒１６の案内作用によって内容物は充分円滑に排出される。大量排出が終了した後には、外蓋８と共に中間蓋６を閉位置に旋回動せしめる。かくすると、中間蓋６のシール筒３４の外周面が蓋本体４の排出案内筒１６の内周面に密接せしめられ、これによって排出案内筒１６を経由する大量排出開口が充分確実に密封される。 When the contents contained in the container are consumed, first, the intermediate lid 6 together with the outer lid 8 positioned in the closed position is viewed from the closed position illustrated in FIGS. 1, 4, and 5. 7 is swung to the open position illustrated in FIG. 7 to expose the closed wall 10 of the lid body 4. Then, the pulling means 22 is put on a finger and pulled upward to break the breakable line 20 to remove the removal region 18 from the blocking wall 10 to create a relatively large mass discharge opening in the blocking wall 10. The intermediate lid 6 is returned to the closed position together with the outer lid 8.
When discharging a small amount of the contents stored in the container, the outer lid 8 is swung from the closed position shown in FIGS. 1, 4 and 5 to the open position shown in FIG. The shielding wall 44 in which the opening is formed is exposed, and then the container is turned upside down to compress the body of the container. As a result, the internal pressure of the container is raised, the shielding wall 44 is deformed upward as shown by a two-dot chain line in FIG. 6, and the cross-shaped slit 46 is expanded as shown by a two-dot chain line in FIGS. Then, a small amount discharge opening is formed, and a small amount of contents are discharged from the small amount discharge opening. After discharging the desired amount of contents, the compression of the body of the container is released and the internal pressure of the container is returned to the atmospheric pressure, so that the shielding wall 44 returns to the original concave shape and the extension of the slit 46 is released so that the slit 46 is released. Closed. This stops a small amount of the contents from being discharged and prevents dripping. When the outer lid 8 is returned to the closed position, the sealing portion 62 of the outer lid 8 is brought into close contact with the upper surface of the shielding wall 44, and thus the slit 46 in which the small amount discharge opening is formed is sufficiently securely sealed.
When discharging a large amount of contents contained in the container, the intermediate lid 6 is illustrated in FIG. 7 from the closed position illustrated in FIGS. 1, 4 and 5 together with the outer lid 8 positioned in the closed position. Rotate to the open position to expose the closing wall 10 of the lid body 4. Next, when the container is tilted, the contents can be discharged in large quantities through the large discharge opening. When a large amount of content is discharged through the generated large discharge opening, the content is discharged sufficiently smoothly by the guide action of the discharge guide tube 16. After the mass discharge is completed, the intermediate lid 6 is turned to the closed position together with the outer lid 8. In this way, the outer peripheral surface of the seal cylinder 34 of the intermediate lid 6 is brought into close contact with the inner peripheral surface of the discharge guide cylinder 16 of the lid body 4, thereby sufficiently reliably sealing the large volume discharge opening via the discharge guide cylinder 16. .

図示の実施形態においては、蓋本体４の閉塞壁１０における排出案内筒１６よりも半径方向内側に除去領域１８を規定する破断可能ライン２０を形成すると共に、除去領域１８の上面に引張手段２２を形成し、引張手段２２を引っ張ることによって除去領域１８を除去して大量排出開口を形成するように構成されているが、これに代えて蓋本体の４の閉塞壁１０における排出案内筒１６よりも半径方向内側に所要形状の大量排出開口を予め形成することもできる。また、図示の実施形態における小量排出部材４２は容器内圧が上昇せしめられると拡張されて小量排出開口を生成するスリット４６が形成されている形態であるが、所望ならば他の形態の小量排出部材、例えば特許第４０４３６８２号公報に開示されている弁板を備えた形態の小量排出部材を採用することもできる。   In the illustrated embodiment, a breakable line 20 that defines the removal region 18 is formed radially inward of the closing wall 10 of the lid body 4 with respect to the discharge guide tube 16, and the tension means 22 is provided on the upper surface of the removal region 18. The removal area 18 is formed by forming and pulling the pulling means 22 so as to form a large discharge opening, but instead of this, the discharge guide cylinder 16 in the closing wall 10 of the lid body 4 is more suitable. A large-volume discharge opening having a required shape can be formed in advance in the radial direction. Further, the small amount discharge member 42 in the illustrated embodiment is formed with a slit 46 that is expanded when the internal pressure of the container is increased to generate a small amount discharge opening. For example, a small amount discharge member having a valve plate disclosed in Japanese Patent No. 4043682 may be employed.
