In the illustrated embodiment, the top wall 74 is circular. The skirt wall 76 includes a frustoconical upper portion that is inclined radially outward from the outer peripheral edge of the top wall 74 and a cylindrical lower portion. The lower end portion of the skirt wall 76 is connected to the upper end portion of the side wall 32 of the lid member 6 through a hinge means 78 which may be in a known form, and the outer lid 8 is shown in FIGS. Is pivotable between a closed position shown in FIG. 6 and an open position shown in FIG. On the diametrically opposite side of the hinge means 78, an arc-shaped protruding piece 80 (FIGS. 2, 3, 6, and 7) on which the finger can be put on the outer peripheral surface of the skirt wall 76 when the outer lid 8 is swung. Is formed). An annular locking projection 82 is formed at the lower end of the inner peripheral surface of the skirt wall 76. Interfering means 84 is further disposed on the inner peripheral surface of the skat wall 76. In the illustrated embodiment, the interference means 84 has a pair of plate-like pieces 86 (FIG. 3) protruding horizontally from the inner peripheral surface of the skirt wall 76 at intervals in the circumferential direction on the diametrically opposite side of the hinge means 78. For example). The plate-like piece 86 is located slightly above the locking protrusion 82. A pressing means 88 is also disposed on the inner peripheral surface of the skirt wall 76. In the illustrated embodiment, the pressing means 88 has three pieces projecting from the inner peripheral surface of the skirt wall 76 and the inner peripheral surface of the top wall 74 at intervals in the circumferential direction on the diametrically opposite side of the hinge means 78. It consists of a pressing piece 90 (see FIG. 3). Each of the pressing pieces 90 extends substantially vertically, and each protruding edge is inclined outwardly downward.
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７６の内周面下端部に形成されている係止突状８２が蓋部材６の係止突条３４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。更に、外蓋８が閉位置に位置せしめられている時には、押圧手段８８が蓋部材６の内蓋片４８の外面（即ちシールリング５０が形成されている面に対して反対側の面）に当接して内蓋片４８を閉位置に強制し、かくして排出筒４２の小量排出開口４４を充分確実に密封する。外蓋８が図６に図示する位置まで開動せしめられる際には、押圧手段８８が内蓋片４８の外面から充分に離隔せしめられると共に、外蓋８のスカート壁７６の内周面に形成されている干渉手段８４が内蓋片４８の内面両側部に当接して内蓋片４８に干渉し始める。そして、外蓋８の開動に付随して内蓋片４８も開動せしめられ、次いで外蓋８の干渉手段８４が内蓋片４８から離隔せしめられる。外蓋８を図６に図示する開位置から図１、図４及び図５に図示する閉位置に旋回動せしめる際には、外蓋８のスカート壁７６に形成されている干渉手段８４が開位置に位置せしめられている内蓋片４８の外面両側部に当接して内蓋片４８に干渉し始める。そして、外蓋８の閉動に付随して内蓋片４８も閉動せしめられて、内蓋片４８は排出筒４２の小量排出開口４４を密封する閉位置にせしめられる。しかる後に、外蓋８の干渉手段８４は内蓋片４８から離隔せしめられる。外蓋８の干渉手段８４及び押圧手段８８と蓋部材６の内蓋片４８との相互関係自体は公知であり、例えば特開２０１０−１２６１９１号公報に詳細に記載されているので、本明細書においては外蓋８の干渉手段８４及び押圧手段８８と蓋部材６の内蓋片４８との相互関係についての詳細な説明は省略する。 When the outer lid 8 is positioned at the closed position shown in FIGS. 1, 4, and 5, the locking protrusion 82 formed on the lower end portion of the inner peripheral surface of the skirt wall 76 of the outer lid 8 is the lid. The outer cover 8 is maintained in the closed position by being engaged with the engaging protrusion 34 of the member 6. Further, when the outer lid 8 is positioned at the closed position, the pressing means 88 is placed on the outer surface of the inner lid piece 48 of the lid member 6 (that is, the surface opposite to the surface on which the seal ring 50 is formed). The inner lid piece 48 is forced to the closed position by abutting, and thus the small amount discharge opening 44 of the discharge tube 42 is sufficiently securely sealed. When the outer lid 8 is opened to the position shown in FIG. 6, the pressing means 88 is sufficiently separated from the outer surface of the inner lid piece 48 and is formed on the inner peripheral surface of the skirt wall 76 of the outer lid 8. The interfering means 84 that is in contact with both side surfaces of the inner lid piece 48 starts to interfere with the inner lid piece 48. Then, the inner lid piece 48 is also opened along with the opening movement of the outer lid 8, and then the interference means 84 of the outer lid 8 is separated from the inner lid piece 48. When the outer lid 8 is swung from the open position shown in FIG. 6 to the closed position shown in FIGS. 1, 4 and 5, the interference means 84 formed on the skirt wall 76 of the outer lid 8 is opened. The inner lid piece 48 starts to interfere with the inner lid piece 48 by coming into contact with both sides of the outer surface of the inner lid piece 48 positioned at the position. As the outer lid 8 is closed, the inner lid piece 48 is also closed, and the inner lid piece 48 is brought into a closed position for sealing the small amount discharge opening 44 of the discharge cylinder 42. Thereafter, the interference means 84 of the outer lid 8 is separated from the inner lid piece 48. The interrelationship between the interference means 84 and pressing means 88 of the outer lid 8 and the inner lid piece 48 of the lid member 6 is known per se and is described in detail in, for example, Japanese Patent Application Laid-Open No. 2010-126191. The detailed description of the interrelation between the interference means 84 and the pressing means 88 of the outer lid 8 and the inner lid piece 48 of the lid member 6 will be omitted.
蓋本体４に蓋部材６を旋回自在に接続しているヒンジ手段７０と蓋部材６に外蓋８を旋回自在に接続しているヒンジ手段７８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に蓋部材６を旋回自在に接続しているヒンジ手段７０と蓋部材６に外蓋８を旋回自在に接続しているヒンジ手段７８とは９０度の角度間隔をおいて配設されている。 The hinge means 70 for pivotally connecting the lid member 6 to the lid body 4 and the hinge means 78 for pivotally connecting the outer lid 8 to the lid member 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, hinge means 70 for pivotally connecting the lid member 6 to the lid body 4 and the outer lid 8 to the lid member 6. Are disposed at an angular interval of 90 degrees with respect to the hinge means 78 that is pivotably connected to the hinge means 78.
図１、図４及び図５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９２も図示されている。合成樹脂又はガラス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９２を有し、かかる口頸部９２の外周面上端部には環状被係止突条９４が形成されている。 1, 4, and 5, the container neck 2 of the container to which the container lid 2 is applied is shown together with the container lid 2 configured according to the present invention. A container that can be formed of synthetic resin or glass has a cylindrical mouth and neck portion 92 as a whole, and an annular locked protrusion 94 is formed on the upper end of the outer peripheral surface of the mouth and neck portion 92.
例えば辣油、食酢或いはコーヒー用液体クリームの如き液状内容物を容器内に収容した後に口頸部９２に容器蓋２を装着して口頸部９２を密封する際には、蓋部材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９２に被嵌し、次いで口頸部９２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の側壁１２の内周面に形成されている係止突条２６が口頸部９２の外周面に形成されている被係止突条９４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 92 and the mouth / neck portion 92 is sealed after the liquid content such as coconut oil, vinegar or coffee liquid cream is contained in the container, the lid member 6 and the outer lid 8, the container lid 2, which is positioned in the closed position, is fitted on the mouth and neck portion 92, and then the container lid 2 is forced downward with respect to the mouth and neck portion 92. Thus, as clearly shown in FIGS. 4 and 5, the locking protrusion 26 formed on the inner peripheral surface of the side wall 12 of the lid body 4 is formed on the outer peripheral surface of the mouth-and-neck portion 92. The ridge 94 is elastically climbed over and locked under 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と共に蓋部材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９８を生成し、しかる後に外蓋８と共に蓋部材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動せしめる。かくすると、外蓋８の旋回動に付随して蓋部材６の内蓋片４８も図４に図示する閉位置から図６に図示する開位置に旋回動せしめられ、排出筒４２の小量排出開口４４が開放される。しかる後においては、容器を傾動せしめて容器蓋２に配設されている小量排出開口４４を下方に指向せしめた状態において、弁部材５８、さらに詳しくは支持片５６の円板状片６２、を下方に押圧せしめる。支持片５６の円板状片６２を下方に押圧せしめた状態にあっては、板状片６０が弾性的に撓み、弁部材５８の主部６５の上面周縁部と遮蔽壁３０に形成された膨出部３８の上壁部３８ｃの内面との密着が解除されることによって外気導入孔５２が開口される。かくすると、外気が外気導入孔５２を通って容器内に漸次導入されることに起因して小量排出開口４４を通して内容物が円滑に連続的に排出される。内容物の排出量は弁部材５８を押圧して外気導入孔５２を開口し続ける時間を調整することによって適宜に設定することができる。故に、煩雑な操作を繰り返し遂行することなく小量排出開口４４を通して所要量の内容物を比較的長時間を要することなく円滑に排出することができる。小量排出開口４４を通した内容物の排出を停止する場合には、弁手段５４の押圧を解除する。弁手段５４の押圧が解除されると、支持片５６は弾性的に復元され、弁部材５８の主部６５の上面が外気導入孔５２よりも外側域において膨出部３８の上壁部３８ｃの内面と密着せしめられ、外気導入孔５２が閉じられる。これにより、容器内に外気が導入されることはなく、小量排出開口４４を通した内容物の排出は停止される。小量排出が終了した後には、外蓋８を閉位置に旋回動せしめる。かくすると、外蓋８の旋回動に付随して内蓋片４８も閉位置に旋回動せしめられ、排出筒４２の小量排出開口４４がより確実に密封される。
容器内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と共に蓋部材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１８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９８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９８から大量排出される内容物は、排出案内筒１６に案内されて充分円滑に流動せしめられる。大量排出が終了した後には、外蓋８と共に蓋部材６を閉位置に旋回動せしめる。かくすると、蓋部材６のシール筒３６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を経由する排出路が充分確実に密封される。
When the contents contained in the container are consumed, first, the lid member 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 98 in the blocking wall 10. Later, the lid member 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. As a result, the inner lid piece 48 of the lid member 6 is also swung from the closed position shown in FIG. 4 to the open position shown in FIG. The opening 44 is opened. Thereafter, in a state where the container is tilted and the small amount discharge opening 44 disposed in the container lid 2 is directed downward, the valve member 58, more specifically, the disk-shaped piece 62 of the support piece 56, Press down. In a state where the disk-shaped piece 62 of the support piece 56 is pressed downward, the plate-shaped piece 60 is elastically bent and formed on the upper peripheral edge of the main portion 65 of the valve member 58 and the shielding wall 30. The outside air introduction hole 52 is opened by releasing the close contact with the inner surface of the upper wall portion 38c of the bulging portion 38. In this way, the contents are smoothly and continuously discharged through the small amount discharge opening 44 because the outside air is gradually introduced into the container through the outside air introduction hole 52. The discharge amount of the contents can be appropriately set by adjusting the time during which the valve member 58 is pressed to keep the outside air introduction hole 52 open. Therefore, a required amount of contents can be smoothly discharged through the small amount discharge opening 44 without requiring a relatively long time without repeatedly performing complicated operations. When stopping the discharge of the contents through the small amount discharge opening 44, the pressing of the valve means 54 is released. When the pressure of the valve means 54 is released, the support piece 56 is elastically restored, and the upper surface of the main portion 65 of the valve member 58 is located outside the outside air introduction hole 52 in the upper wall portion 38c of the bulging portion 38. The outside air introduction hole 52 is closed by being brought into close contact with the inner surface. Thereby, outside air is not introduced into the container, and the discharge of the contents through the small amount discharge opening 44 is stopped. After the small amount is discharged, the outer lid 8 is turned to the closed position. Thus, the inner lid piece 48 is also pivoted to the closed position in association with the pivoting movement of the outer lid 8, and the small amount discharge opening 44 of the discharge cylinder 42 is more reliably sealed.
When discharging a large amount of contents contained in the container, the lid member 6 is moved from the closed position shown in FIGS. 1, 4 and 5 to FIG. 7 together with the outer lid 8 positioned in the closed position. It is swung to the open position shown in the figure, and the closing wall 18 of the lid body 4 is exposed. Next, when the container is tilted, the contents can be discharged in large quantities through the large discharge opening 98. The contents discharged in large quantities from the generated large discharge opening 98 are guided to the discharge guide cylinder 16 and flowed sufficiently smoothly. After the mass discharge is completed, the lid member 6 is turned to the closed position together with the outer lid 8. In this way, the outer peripheral surface of the seal cylinder 36 of the lid member 6 is brought into close contact with the inner peripheral surface of the discharge guide cylinder 16 of the lid main body 4, thereby sufficiently securely sealing the discharge path passing through 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９８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９８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弁手段５４を構成する支持片５６の板状片６０は膨出部３８における上壁部３８ｃの後方端より前方に延出せしめられているが、これに代えて板状片は外気導入孔５２の前方端より後方に延出せしめられるようにしてもよい。板状片が外気導入孔５２の前方端より後方に延出せしめられるようにすると、容器内に収容されている内容物を小量排出すべく小量排出開口４４を下方に指向せしめた状態で弁部材５８の円板状片６２を下方に押圧せしめると、板状片は外気導入孔５２の前方端に接続された基端を中心として図４において時計方向に弾性的に撓み円板状片６２は図４において時計方向に変位せしめられる。従って、弁部材５８の主部６５の上面周縁部と遮蔽壁３０に形成された膨出部３８の上壁部３８ｃの内面との密着は、下方に指向せしめられた小量排出開口４４と直径方向反対側から漸次解除される。これにより、小量排出開口４４を下方に指向せしめた状態で弁部材５８の円板状片６２を下方に押圧せしめる場合であっても、弁部材５８の主部６５の上面周縁部と遮蔽壁３０に形成された膨出部３８の上壁部３８ｃの内面との密着が解除された部位から内容物が漏洩されにくくなる。
更にまた、図示の実施形態における弁手段５４を構成する支持片５６は円板状片６２を有しこの円板状片６２の上面の高さは膨出部３８における上壁部３８ｃの上面の高さと同一にせしめられているが、これに代えて上面の高さが上壁部３８ｃの上面の高さより幾分上方である円筒形状片を有するようにしてもよい。支持片５６がこの円筒形状片を有するようにすると、容器内に収容されている内容物を小量排出すべく弁部材５８の円筒形状片を下方に押圧せしめる動作が円板状片６２と比較して容易になることに加えて、弁部材５８を押圧した指による外気導入孔５２の閉塞が生じにくくなる。
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 removed by forming and pulling the pulling means 22 to form the mass discharge opening 98. Instead, the discharge guide tube 16 in the closing wall 10 of the lid body 4 is used. Also, a large-volume discharge opening 98 having a required shape can be formed in advance in the radial direction.
Further, the plate-like piece 60 of the support piece 56 constituting the valve means 54 in the illustrated embodiment is extended forward from the rear end of the upper wall portion 38c in the bulging portion 38, but instead of this, a plate The shape piece may extend rearward from the front end of the outside air introduction hole 52. When the plate-like piece is extended rearward from the front end of the outside air introduction hole 52, the small amount discharge opening 44 is directed downward to discharge a small amount of the contents stored in the container. When the disk-shaped piece 62 of the valve member 58 is pressed downward, the plate-shaped piece is elastically bent clockwise in FIG. 4 around the base end connected to the front end of the outside air introduction hole 52. 62 is displaced clockwise in FIG. Therefore, the close contact between the peripheral edge of the upper surface of the main portion 65 of the valve member 58 and the inner surface of the upper wall portion 38c of the bulging portion 38 formed on the shielding wall 30 and the diameter of the small amount discharge opening 44 directed downward. It is gradually released from the opposite direction. Thus, even when the disk-like piece 62 of the valve member 58 is pressed downward with the small amount discharge opening 44 directed downward, the peripheral edge of the upper surface of the main portion 65 of the valve member 58 and the shielding wall. The contents are less likely to leak from the portion where the close contact with the inner surface of the upper wall portion 38c of the bulging portion 38 formed in 30 is released.
Furthermore, the support piece 56 constituting the valve means 54 in the illustrated embodiment has a disc-like piece 62, and the height of the upper surface of the disc-like piece 62 is the same as that of the upper surface of the upper wall portion 38c in the bulging portion 38. Although the height is the same as the height, a cylindrical piece may be provided in which the height of the upper surface is somewhat higher than the height of the upper surface of the upper wall portion 38c. When the support piece 56 has this cylindrical piece, the operation of pressing the cylindrical piece of the valve member 58 downward to discharge a small amount of the contents accommodated in the container is compared with the disc-like piece 62. In addition to being easy, the outside air introduction hole 52 is less likely to be blocked by the finger pressing the valve member 58.
