Description

本発明は、容器の容器口部に装着されるキャップに関するものである。 The present invention relates to a cap attached to a container mouth portion of a container.

従来、容器の容器口部に装着されるキャップとして、容器口部に装着されるキャップ本体と、ヒンジを介してキャップ本体に連結される蓋体とを備えるキャップが知られている。そのようなキャップにおいて、例えば、特許文献１には、キャップ本体に蓋体を被冠させた際、キャップ本体の筒状上端面に垂れた付着する内容物の飛散を防ぐキャップが開示されている。このキャップは、キャップ本体の上面に、吐出口から垂れた内容物を収容する収容溝を形成し、収容溝に内容物を溜めることで、キャップ本体に蓋体を被冠させた際の内容物の飛散を防ぐように構成されている。 Conventionally, as a cap attached to the container mouth portion of a container, a cap including a cap main body attached to the container opening portion and a lid body connected to the cap main body via a hinge is known. In such a cap, for example, Patent Document 1 discloses a cap that prevents scattering of adhered contents that hang down on the tubular upper end surface of the cap body when the cap body is covered with a lid. .. In this cap, an accommodating groove for accommodating the contents hanging from the discharge port is formed on the upper surface of the cap body, and the contents are accumulated in the accommodating groove, so that the contents when the cap body is covered with the lid. It is configured to prevent the scattering of.

特許第３７９６６６８号公報Japanese Patent No. 3796668

しかしながら、特許文献１に記載された発明では、内容物が収容溝に充満した状態で、キャップ本体に蓋体を被冠させたとき、収容溝に溜まった内容物が飛散する虞がある。 However, in the invention described in Patent Document 1, when the cap body is covered with the lid while the contents are filled in the accommodating groove, the contents accumulated in the accommodating groove may be scattered.

本発明は、上記課題に鑑みてなされたものであり、蓋体を閉じた際、キャップ本体の周縁上に残存する内容物の飛散を防ぐことができるキャップを提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a cap capable of preventing scattering of contents remaining on the peripheral edge of the cap body when the lid is closed.

本発明は、上記課題を解決するための手段として、請求項１に記載した発明は、容器口部に装着されるキャップ本体と、ヒンジを介して前記キャップ本体にヒンジ結合された蓋体とを備えたキャップであって、前記キャップ本体は、前記容器口部の外壁面に嵌合される胴部と、前記容器口部の内壁面に嵌合される円筒状主嵌合壁部と、前記容器口部と連通する吐出通路を有する円筒状案内部と、を備え、前記蓋体は、被冠時に前記胴部と前記円筒状主嵌合壁部との間のキャップ本体に当接するように、前記蓋体の天面部の下壁面から垂設される円筒状下降規制部を有し、前記キャップ本体の前記胴部の、前記ヒンジとの結合部を除く外周上縁部には、前記胴部の径方向外側下方に傾斜する傾斜面が形成され、前記蓋体は、被冠時に前記傾斜面に非接触である非接触下面を備えることを特徴とするものである。 According to the first aspect of the present invention, as a means for solving the above problems, a cap body attached to a container mouth portion and a lid body hinged to the cap body via a hinge are provided. The cap body is provided with a body portion fitted to the outer wall surface of the container mouth portion, a cylindrical main fitting wall portion fitted to the inner wall surface of the container mouth portion, and the above. A cylindrical guide portion having a discharge passage communicating with the container mouth portion is provided, and the lid body is brought into contact with the cap body between the body portion and the cylindrical main fitting wall portion when crowned. The upper peripheral edge of the body of the cap body, excluding the joint with the hinge, has a cylindrical lowering control portion that is vertically hung from the lower wall surface of the top surface of the lid. An inclined surface that is inclined outward and downward in the radial direction of the portion is formed, and the lid body is provided with a non-contact lower surface that is non-contact with the inclined surface at the time of being crowned.

請求項１に記載の発明では、蓋体の下面は、被冠時に傾斜面に非接触である非接触下面を有すため、キャップ本体に蓋体が被冠したとき、円筒状下降規制部がキャップ本体に当接して、蓋体の下降を止め、蓋体の下面（非接触下面）がキャップ本体の上端面に接触されない。これにより、キャップ本体の周縁上に内容物が付着されていても、内容物が飛散しにくくなる。また、胴部には、その外周上縁部に、胴部の径方向外側下方に向かって傾斜する傾斜面を形成することで、内容物が胴部の上端面に付着しても、内容物が傾斜面に沿って垂れ落ちるため、キャップ本体に蓋体を被冠した際に生じる飛散を抑制することができる。
さらに、蓋体には、胴部と円筒状主嵌合壁部との中間のキャップ本体に当接するように、蓋体の天面部の下壁面から垂設された円筒状下降規制部を設けることで、キャップ本体に蓋体を被冠したとき、円筒状下降規制部の先端がキャップ本体の上面に接触することにより、キャップ本体と蓋体との周縁間の間隔を維持することができ、蓋体の閉位置を規制し、かつ、打栓時や物流時の蓋体の座屈を防ぐことができる。 In the invention according to claim 1, since the lower surface of the lid has a non-contact lower surface that is not in contact with the inclined surface at the time of being crowned, when the lid is crowned on the cap body, the cylindrical lowering regulating portion is formed. It comes into contact with the cap body to stop the lowering of the lid body, and the lower surface (non-contact lower surface) of the lid body is not brought into contact with the upper end surface of the cap body. As a result, even if the contents are attached to the peripheral edge of the cap body, the contents are less likely to scatter. Further, by forming an inclined surface on the upper peripheral edge of the body portion so as to incline outward and downward in the radial direction of the body portion, even if the content adheres to the upper end surface of the body portion, the content is contained. Since it hangs down along the inclined surface, it is possible to suppress the scattering that occurs when the lid body is covered with the cap body.
Further, the lid body shall be provided with a cylindrical lowering regulation portion suspended from the lower wall surface of the top surface portion of the lid body so as to abut the cap body intermediate between the body portion and the cylindrical main fitting wall portion. When the cap body is covered with the lid, the tip of the cylindrical lowering regulation portion comes into contact with the upper surface of the cap body, so that the distance between the periphery of the cap body and the lid can be maintained, and the lid can be maintained. It is possible to regulate the closed position of the body and prevent the lid from buckling during plugging or distribution.

請求項２に記載した発明は、請求項１に記載した発明において、前記蓋体の、前記キャップ本体への被冠時、前記非接触下面と前記傾斜面との間に隙間が形成され、該隙間の寸法が０．３ｍｍ以上１．０ｍｍ以下であることを特徴とするものである。 The invention according to claim 2 is the invention according to claim 1, wherein a gap is formed between the non-contact lower surface and the inclined surface when the lid body is crowned with the cap body. It is characterized in that the size of the gap is 0.3 mm or more and 1.0 mm or less.

本項に係るキャップは、キャップ本体に蓋体が被冠したとき、非接触下面と傾斜面との間に隙間が形成されるため、非接触下面がキャップ本体の上端面に接触されない。これにより、キャップ本体の上端面に内容物が付着されていても、内容物の飛散を防ぐことができる。 In the cap according to this item, when the cap body is covered with the lid, a gap is formed between the non-contact lower surface and the inclined surface, so that the non-contact lower surface does not come into contact with the upper end surface of the cap body. As a result, even if the contents are attached to the upper end surface of the cap body, the contents can be prevented from scattering.

請求項３に記載した発明は、請求項１又は２に記載した発明において、前記傾斜面の形成範囲は、前記キャップ本体の中心軸を中心とする中心角度２５０°以上の範囲に形成され、前記非接触下面の形成範囲は、前記蓋体の中心軸を中心とする中心角度２５０°以上の範囲に形成されていることを特徴とするものである。 The invention according to claim 3 is the invention according to claim 1 or 2, wherein the formed range of the inclined surface is formed in a range of a central angle of 250 ° or more about the central axis of the cap body. The non-contact lower surface is formed in a range having a central angle of 250 ° or more centered on the central axis of the lid.

本項に係るキャップは、傾斜面の形成範囲がキャップ本体の中心軸を中心とする中心角度２５０°以上の範囲に形成されることで、より広い範囲で内容物を垂れ落とすことができ、キャップ本体の上端面に付着される内容物の残量をより減らすことができる。さらに、非接触下面の形成範囲が蓋体の中心軸を中心とする中心角度２５０°以上の範囲に形成されることで、キャップ本体に蓋体が被冠した際、その範囲で、蓋体５の胴部の下面が環状水平壁部の上面に接触しないため、内容物の飛散をより確実に防ぐことができる。 The cap according to this section can hang down the contents in a wider range by forming the inclined surface in a range of a central angle of 250 ° or more centered on the central axis of the cap body, and the cap. The remaining amount of contents adhering to the upper end surface of the main body can be further reduced. Further, the non-contact lower surface is formed in a range of a central angle of 250 ° or more centered on the central axis of the lid, so that when the cap body is covered with the lid, the lid 5 is formed in that range. Since the lower surface of the body portion of the body does not come into contact with the upper surface of the annular horizontal wall portion, it is possible to more reliably prevent the contents from scattering.

本発明のキャップによれば、蓋体を閉じた際、キャップ本体の周縁上に残存する内容物の飛散を防ぐことができるキャップを提供することができる。 According to the cap of the present invention, it is possible to provide a cap capable of preventing scattering of the contents remaining on the peripheral edge of the cap body when the lid is closed.

以下、本発明の第１実施形態に係るキャップの構成を図１〜図７に基づいて詳細に説明する。
本発明の第１実施形態に係るキャップ１Ａは、内部に逆止弁を有するものであり、容器２の容器口部３に打栓により装着される。キャップ１Ａは、内容物の吐出孔２５を有するキャップ本体４と、キャップ本体４にヒンジ６を介して連結される蓋体５とから概略構成される。 Hereinafter, the configuration of the cap according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7.
The cap 1A according to the first embodiment of the present invention has a check valve inside, and is attached to the container mouth portion 3 of the container 2 by a stopper. The cap 1A is roughly composed of a cap body 4 having a discharge hole 25 for contents and a lid body 5 connected to the cap body 4 via a hinge 6.

まず、キャップ１Ａを被冠する容器２について、図１〜３を参照して説明する。
容器２は、例えば胴部７が変形復元し易いものであり、その内部には液状内容物が充填される。この内容物は、例えば、醤油、ポン酢、ソース、オリーブオイル等、液垂れし易い液状内容物が挙げられる。容器２は、その胴部７を圧搾するなどして内圧を加えることで内容物を吐出させるタイプのものである。容器口部３は、略円筒状に形成される。なお、容器２は、外容器と内容器とからなる二重容器（剥離容器と言われるものも含む）を含む。内容器は、その内部に内容物が充填されると共に内容物の減少に伴いしぼみ変形する可撓性を有するものである。内容器の減容形状を保持するために外容器と内容器との間には外気が吸入されるように構成される。 First, the container 2 covered with the cap 1A will be described with reference to FIGS. 1 to 3.
In the container 2, for example, the body portion 7 is easily deformed and restored, and the inside thereof is filled with a liquid content. Examples of this content include liquid contents that easily drip, such as soy sauce, ponzu sauce, sauce, and olive oil. The container 2 is of a type in which the contents are discharged by applying an internal pressure such as by squeezing the body portion 7. The container mouth portion 3 is formed in a substantially cylindrical shape. The container 2 includes a double container (including a so-called peeling container) composed of an outer container and an inner container. The inner container has the flexibility to be filled with the contents and to be deflated and deformed as the contents are reduced. In order to maintain the reduced volume shape of the inner container, outside air is sucked between the outer container and the inner container.

容器２は、図３に示すように、胴部７と、胴部７から連続して形成される容器口部３とから構成される。容器口部３は、全体として口細円筒状に形成され、有底円筒状の胴部７から連続して形成される。容器口部３は、外径が相違する複数の口部（段部）が軸方向に沿って連続して構成される。具体的には、容器口部３は、上端に配置され軸方向に延びる大径口部６０と、大径口部６０から下方に配置され、その外径が大径口部６０より小径で軸方向に延びる小径口部６１と、小径口部６１から下方に配置され、その外径が大径口部６０より大径で軸方向に延びる最大径口部６２とを備えている。また、上端に位置する大径口部６０と小径口部６１とは、大径口部６０から連続して下方に向かって次第に縮径する縮径口部６３により接続される。小径口部６１と最大径口部６２とは、小径口部６１から連続して下方に向かって次第に拡径する拡径口部６４により接続される。最大径口部６２の下方には、連続して、最大径口部６２より小径で、大径口部６０より大径の、軸方向に延びる支持口部６５が形成される。支持口部６５と胴部７との間には、小径口部６１と略同径の凹状口部６６が形成される。なお、容器口部３にキャップ１Ａを打栓する際、凹状口部６６の外周部位が、打栓機（図示略）にて把持される。 As shown in FIG. 3, the container 2 is composed of a body portion 7 and a container mouth portion 3 formed continuously from the body portion 7. The container mouth portion 3 is formed in a narrow cylindrical shape as a whole, and is continuously formed from a bottomed cylindrical body portion 7. The container mouth portion 3 is composed of a plurality of mouth portions (step portions) having different outer diameters continuously along the axial direction. Specifically, the container mouth portion 3 is arranged at the upper end and extends downward in the axial direction, and is arranged below the large diameter mouth portion 60, and its outer diameter is smaller than that of the large diameter mouth portion 60. It includes a small-diameter port portion 61 extending in the direction, and a maximum-diameter port portion 62 arranged below the small-diameter port portion 61 and having an outer diameter larger than that of the large-diameter port portion 60 and extending in the axial direction. Further, the large-diameter opening portion 60 and the small-diameter opening portion 61 located at the upper end are connected by a reduced-diameter opening portion 63 that is continuously reduced in diameter from the large-diameter opening portion 60 and gradually decreases downward. The small-diameter port portion 61 and the maximum-diameter port portion 62 are connected by a diameter-expanded port portion 64 that continuously and gradually increases in diameter from the small-diameter port portion 61. Below the maximum diameter portion 62, a support port portion 65 extending in the axial direction, which has a diameter smaller than that of the maximum diameter portion 62 and a diameter larger than that of the large diameter portion 60, is continuously formed. A concave opening 66 having substantially the same diameter as the small diameter 61 is formed between the support opening 65 and the body 7. When the cap 1A is plugged into the container mouth portion 3, the outer peripheral portion of the concave mouth portion 66 is gripped by a tapping machine (not shown).

次に、キャップ１Ａの構成について、図３〜図７を参照して説明する。
キャップ１Ａは、キャップ本体４と、蓋体５とからなり、開蓋した状態において、容器２の胴部７を圧搾して容器２に内圧を加え、適量の内容物を吐出した直後（内圧を解除したとき）、使用者が手でキャップ１Ａを操作することなく容器２内を逆止弁１２により密封するものである。 Next, the configuration of the cap 1A will be described with reference to FIGS. 3 to 7.
The cap 1A is composed of a cap body 4 and a lid 5. Immediately after the body 7 of the container 2 is squeezed to apply internal pressure to the container 2 and an appropriate amount of contents are discharged (internal pressure). When released), the inside of the container 2 is sealed by the check valve 12 without the user manually operating the cap 1A.

キャップ本体４は、図３を参照して、概略、容器口部３に打栓される円筒状の主キャップ体１１と、主キャップ体１１の環状壁部１０（後述参照）の上方に配置され、弁部３６が吐出孔２５周辺の環状弁座２６から離脱または着座して吐出孔２５を開閉する逆止弁１２と、主キャップ体１１の円筒状主嵌合壁部１９（後述参照）の上部と嵌合し、逆止弁１２の上方に配置され、吐出孔２５と連通し、吐出孔２５からの内容物を吐出する吐出通路４１を有する中栓１３とから構成される。 The cap body 4 is roughly arranged above the cylindrical main cap body 11 to be plugged into the container mouth 3 and the annular wall portion 10 (see below) of the main cap body 11, with reference to FIG. , A check valve 12 in which the valve portion 36 separates from or sits on the annular valve seat 26 around the discharge hole 25 to open and close the discharge hole 25, and a cylindrical main fitting wall portion 19 (see below) of the main cap body 11. It is composed of an inner plug 13 which is fitted to the upper part, is arranged above the check valve 12, communicates with the discharge hole 25, and has a discharge passage 41 for discharging the contents from the discharge hole 25.

主キャップ体１１は、ポリプロピレン等の合成樹脂から成形され、胴部１８と、胴部１８の内側に同心状に配置される円筒状主嵌合壁部１９と、円筒状主嵌合壁部１９の内壁面から一体的に径方向中心に向かって斜め上方に延び、径方向中央部に吐出孔２５を有する環状壁部１０と、胴部１８の上端と円筒状主嵌合壁部１９の上端とを接続する環状水平壁部２０と、環状水平壁部２０の下面であって、胴部１８と円筒状主嵌合壁部１９との間には同心状に垂設された円筒状副嵌合壁３２と、から構成される。円筒状主嵌合壁部１９の外周面と容器口部３の小径口部６１の内周面とが当接して密封を維持する。胴部１８には、蓋体５がキャップ本体４に被冠されている状態時、使用者の指が蓋体５の把持部５４に引掛けやすいように、ヒンジ６との結合部の反対側の外壁面に舌状の凹部２７が形成されている（図１参照）。凹部２７は、その形成範囲、すなわち、キャップ本体４の中心軸Ｃ１を中心とする中心角度θ２が略９０°である（図５参照）。胴部１８の外周上縁部には、ヒンジ６との結合部を除く部分（すなわち、ヒンジ６の反対側）に、胴部１８の径方向外側下方に傾斜する傾斜面３０が形成されている。傾斜面３０の傾斜角度θ１は、略３０°であり（図４参照）、傾斜面３０の形成範囲、すなわち、キャップ本体４の中心軸Ｃ１を中心とする中心角度θ３が略２５０°以上（第１実施形態では、略３００°（図５参照））である。なお、凹部２７の中心角度θ２は、６０°〜１８０°であってもよい。傾斜面３０の傾斜角度θ１及び中心角度θ３は、内容物の粘度や表面張力等を考慮して適宜変更してもよい。胴部１８の下部内壁面には、突条係止部２１が形成され、容器口部３の最大径口部６２と係合する。円筒状主嵌合壁部１９と胴部１８との間には、容器口部３を嵌合する環状空間２２が形成される。 The main cap body 11 is formed from a synthetic resin such as polypropylene, and has a body portion 18, a cylindrical main fitting wall portion 19 arranged concentrically inside the body portion 18, and a cylindrical main fitting wall portion 19. An annular wall portion 10 extending diagonally upward from the inner wall surface of the body toward the center in the radial direction and having a discharge hole 25 in the central portion in the radial direction, the upper end of the body portion 18, and the upper end of the cylindrical main fitting wall portion 19. A cylindrical sub-fitting that is the lower surface of the annular horizontal wall portion 20 and is concentrically suspended between the body portion 18 and the cylindrical main fitting wall portion 19. It is composed of a wall 32 and. The outer peripheral surface of the cylindrical main fitting wall portion 19 and the inner peripheral surface of the small diameter opening portion 61 of the container opening portion 3 are in contact with each other to maintain the seal. The body 18 is on the opposite side of the joint with the hinge 6 so that the user's fingers can easily hook on the grip 54 of the lid 5 when the lid 5 is covered with the cap body 4. A tongue-shaped recess 27 is formed on the outer wall surface of the above (see FIG. 1). The concave portion 27 has a formation range, that is, a central angle θ2 about the central axis C1 of the cap body 4 of about 90 ° (see FIG. 5). An inclined surface 30 is formed on the outer peripheral upper edge portion of the body portion 18 so as to be inclined outward and downward in the radial direction of the body portion 18 at a portion excluding the joint portion with the hinge 6 (that is, the opposite side of the hinge 6). .. The inclination angle θ1 of the inclined surface 30 is approximately 30 ° (see FIG. 4), and the formation range of the inclined surface 30, that is, the central angle θ3 about the central axis C1 of the cap body 4 is approximately 250 ° or more (the first). In one embodiment, it is approximately 300 ° (see FIG. 5)). The center angle θ2 of the recess 27 may be 60 ° to 180 °. The inclination angle θ1 and the center angle θ3 of the inclined surface 30 may be appropriately changed in consideration of the viscosity of the contents, the surface tension, and the like. A ridge locking portion 21 is formed on the lower inner wall surface of the body portion 18 and engages with the maximum diameter opening portion 62 of the container opening portion 3. An annular space 22 for fitting the container mouth portion 3 is formed between the cylindrical main fitting wall portion 19 and the body portion 18.

円筒状主嵌合壁部１９の下部内壁面には、その周方向全域から一体的に環状壁部１０が径方向中心に向かって斜め上方に延びている。環状壁部１０は截頭円錐状を呈している。環状壁部１０と円筒状主嵌合壁部１９の内壁面とにより上方を開放した空間２４が形成される（図３参照）。環状壁部１０の径方向中心部には略円形状の吐出孔２５が開口される。吐出口２５は、容器口部３内と連通される。吐出孔２５の周辺に環状弁座２６が形成される。環状弁座２６は、倒立円錐状面２８に形成される。 On the lower inner wall surface of the cylindrical main fitting wall portion 19, an annular wall portion 10 integrally extends obliquely upward from the entire circumferential direction toward the center in the radial direction. The annular wall portion 10 has a conical shape. An open space 24 is formed by the annular wall portion 10 and the inner wall surface of the cylindrical main fitting wall portion 19 (see FIG. 3). A substantially circular discharge hole 25 is opened at the radial center of the annular wall portion 10. The discharge port 25 communicates with the inside of the container port 3. An annular valve seat 26 is formed around the discharge hole 25. The annular valve seat 26 is formed on the inverted conical surface 28.

環状水平壁部２０の上面には、その外周部に上方に突起する環状突起部１７が形成される。円筒状主嵌合壁部１９の上部内壁面には、周方向に沿って環状に延びる環状嵌合凹部２３が形成される。環状突起部１７には、その外壁面に周方向に沿って環状に延びる突条係止部３１が形成される。 On the upper surface of the annular horizontal wall portion 20, an annular projection portion 17 projecting upward is formed on the outer peripheral portion thereof. An annular fitting recess 23 extending in an annular shape along the circumferential direction is formed on the upper inner wall surface of the cylindrical main fitting wall portion 19.

次に、第１実施形態に係るキャップ１Ａの作用を説明する。
内容物を吐出させるときには、まず、蓋体５を開いて、キャップ本体４の中栓１３を外部に露出させる。
次に、中栓１３の吐出通路４１が下方を向くように容器１を傾けて吐出姿勢にした状態で、容器２の胴部７を圧搾して容器２に内圧を加えると、容器２の内圧が逆止弁１２の弁部３６の下壁面全域に作用することで、逆止弁１２の各弾性片３５が屈曲するように弾性変形して、弁部３６の外周部（倒立円錐状面２９）が環状壁部１０の吐出孔２５周辺の環状弁座２６（倒立円錐状面２８）から離脱される。この結果、環状壁部１０の吐出孔２５が開放されて、適量の内容物が容器口部３内から吐出孔２５、逆止弁１２の各流通孔３７及び中栓１３の吐出通路４１を経て外部に吐出される。 Next, the operation of the cap 1A according to the first embodiment will be described.
When discharging the contents, first, the lid 5 is opened to expose the inner plug 13 of the cap body 4 to the outside.
Next, when the body 7 of the container 2 is squeezed and the internal pressure is applied to the container 2 in a state where the container 1 is tilted so that the discharge passage 41 of the inner plug 13 faces downward and the container 1 is in the discharge posture, the internal pressure of the container 2 is applied. Acts on the entire lower wall surface of the valve portion 36 of the check valve 12 to elastically deform each elastic piece 35 of the check valve 12 so as to bend, and the outer peripheral portion (inverted conical surface 29) of the valve portion 36. ) Is separated from the annular valve seat 26 (inverted conical surface 28) around the discharge hole 25 of the annular wall portion 10. As a result, the discharge hole 25 of the annular wall portion 10 is opened, and an appropriate amount of the contents pass through the discharge hole 25, each flow hole 37 of the check valve 12, and the discharge passage 41 of the inner plug 13 from the inside of the container mouth portion 3. It is discharged to the outside.

その後、容器２の胴部７への圧搾を止めると、容器２への内圧が解除されるために、逆止弁１２の各弾性片３５が復元して、弁部３６の外周部（倒立円錐状面２９）が環状壁部１０の吐出孔２５周辺の環状弁座２６（倒立円錐状面２８）に着座して、弁部３６により環状壁部１０の吐出孔２５が閉塞される。これにより、容器２内が密封状態となる。 After that, when the squeezing of the container 2 onto the body 7 is stopped, the internal pressure on the container 2 is released, so that each elastic piece 35 of the check valve 12 is restored, and the outer peripheral portion (inverted cone) of the valve portion 36 is restored. The shaped surface 29) is seated on the annular valve seat 26 (inverted conical surface 28) around the discharge hole 25 of the annular wall portion 10, and the discharge hole 25 of the annular wall portion 10 is closed by the valve portion 36. As a result, the inside of the container 2 is sealed.

次に、ヒンジ６を折り曲げて蓋体５を、キャップ本体４の上方から覆うように被せれば、蓋体５の胴部５０に設けた突条係止部５３が、下降しながらキャップ本体４（主キャップ体１１）の環状水平壁部２０に設けた突条係止部３１を乗り越えるように係合すると共に、蓋体５の天面部５１に設けた円筒状栓部５２が、キャップ本体４の中栓１３を構成する円筒状案内部４２の上端内部に緊密に嵌合される。このとき、キャップ本体４の環状水平壁部２０の外周縁部に内容物が付着していても、蓋体５の第２下面５６が主キャップ体１１の外周縁部に接触しないので、内容物の飛散が防止される。また、内容物は、胴部１８の傾斜面３０に沿って垂れ落ちるため、環状水平壁部２０の外周縁部に付着しにくくなっている。 Next, when the hinge 6 is bent to cover the lid 5 from above the cap body 4, the ridge locking portion 53 provided on the body 50 of the lid 5 descends while the cap body 4 The cylindrical plug portion 52 provided on the top surface portion 51 of the lid body 5 is engaged with the cap body 4 so as to get over the ridge locking portion 31 provided on the annular horizontal wall portion 20 of the (main cap body 11). It is tightly fitted inside the upper end of the cylindrical guide portion 42 constituting the inner plug 13. At this time, even if the content is attached to the outer peripheral edge of the annular horizontal wall portion 20 of the cap body 4, the second lower surface 56 of the lid 5 does not come into contact with the outer peripheral edge of the main cap body 11, so that the content is present. Is prevented from scattering. Further, since the contents hang down along the inclined surface 30 of the body portion 18, it is difficult for the contents to adhere to the outer peripheral edge portion of the annular horizontal wall portion 20.

そして、蓋体５をキャップ本体４に被冠することで、キャップ本体４内（中栓１３と、逆止弁１２及び環状壁部１０との間）への異物の混入を抑制すると共に、容器１内を二重で密封することができる。しかも、キャップ本体４内は蓋体５により密封されているので、環状壁部１０上の空間２４に内容物が若干残存したとしても、その内容物が酸化しにくくなる。 Then, by covering the cap body 5 with the lid body 5, foreign matter is suppressed from being mixed into the cap body 4 (between the inner plug 13 and the check valve 12 and the annular wall portion 10), and the container is container. The inside of 1 can be double-sealed. Moreover, since the inside of the cap body 4 is sealed by the lid body 5, even if some contents remain in the space 24 on the annular wall portion 10, the contents are less likely to be oxidized.

上記構成を有する第１実施形態のキャップ１Ａによれば、次のような作用効果を得ることができる。
主キャップ本体１１に蓋体５を被冠したとき、キャップ本体４の環状水平壁部２０の外周縁部に内容物が付着していても、円筒状下降規制部５５が環状水平壁部２０に当接した位置で、突条係止部５３と突条係止部３１とが係合するので、蓋体５の下端面（第２下面５６）が環状水平壁部２０の外周縁部に接触せず、内容物の飛散を防ぐことができる。 According to the cap 1A of the first embodiment having the above configuration, the following effects can be obtained.
When the main cap body 11 is covered with the lid 5, even if the contents are attached to the outer peripheral edge of the annular horizontal wall portion 20 of the cap body 4, the cylindrical lowering restricting portion 55 is attached to the annular horizontal wall portion 20. Since the ridge locking portion 53 and the ridge locking portion 31 are engaged at the abutting position, the lower end surface (second lower surface 56) of the lid 5 comes into contact with the outer peripheral edge portion of the annular horizontal wall portion 20. It is possible to prevent the contents from scattering.

また、内容物が環状水平壁部２０の外周縁部に付着したとしても、胴部１８の傾斜面３０によって、内容物が垂れ落ちる。これにより、環状水平壁部２０の外周縁部に内容物が残りにくくなり、内容物が残ったとしても、環状水平壁部２０の外周縁部に内容物の付着量が少なく、隙間Ｄを形成したことで、主キャップ本体１１に蓋体５を被冠したときに生じる内容物の飛散を抑制することができる。 Further, even if the contents adhere to the outer peripheral edge portion of the annular horizontal wall portion 20, the contents hang down due to the inclined surface 30 of the body portion 18. As a result, the contents are less likely to remain on the outer peripheral edge of the annular horizontal wall portion 20, and even if the contents remain, the amount of the contents adhering to the outer peripheral edge of the annular horizontal wall portion 20 is small and a gap D is formed. As a result, it is possible to suppress the scattering of the contents that occur when the lid body 5 is covered with the main cap body 11.

さらに、蓋体５を被冠したとき、主キャップ体１１と蓋体５との周縁に隙間が生じても、円筒状下降規制部５５が環状水平壁部２０に当接されるので、内容物の飛散を防止する隙間Ｄを維持することができる。また、円筒状下降規制部５５と環状水平壁部２０との当接位置が、容器２の容器口部３の大径口部６０の略上部に位置しているので（図３及び図４参照）、蓋体５の被冠時に生じる蓋体５（円筒状下降規制部５５）の被冠衝撃を受けることができる。 Further, when the lid body 5 is covered, even if there is a gap between the main cap body 11 and the lid body 5, the cylindrical lowering restricting portion 55 is brought into contact with the annular horizontal wall portion 20, so that the contents It is possible to maintain a gap D that prevents the scattering of the material. Further, since the contact position between the cylindrical lowering regulation portion 55 and the annular horizontal wall portion 20 is located substantially above the large-diameter opening portion 60 of the container opening portion 3 of the container 2 (see FIGS. 3 and 4). ), The impact of the lid 5 (cylindrical lowering regulation portion 55) generated when the lid 5 is crowned can be received.

胴部１８の傾斜面３０の中心角度θ３が２５０°以上であるため、より広い範囲で内容物を垂れ落とすことができ、キャップ本体４の上端面に付着される内容物の残量をより減らすことができる。さらに、第２下面５６の中心角度θ４が２５０°以上とすることで、キャップ本体４に蓋体５が被冠した際、その範囲で、蓋体５の胴部５０の下面が環状水平壁部２０の上面に接触しないため、内容物の飛散をより確実に防ぐことができる。 Since the central angle θ3 of the inclined surface 30 of the body portion 18 is 250 ° or more, the contents can be hung down in a wider range, and the remaining amount of the contents adhering to the upper end surface of the cap body 4 is further reduced. be able to. Further, by setting the center angle θ4 of the second lower surface 56 to 250 ° or more, when the lid body 5 is covered with the cap body 4, the lower surface of the body portion 50 of the lid body 5 is an annular horizontal wall portion within that range. Since it does not come into contact with the upper surface of the 20, it is possible to more reliably prevent the contents from scattering.
