中栓付きの注出容器として、容器体の口頸部上部を小外径部として、この小外径部への嵌着させた外筒と、口頸部内面へ液密に嵌合させた内筒とを頂板の外周部から垂下するとともに、内筒内側の頂板部分に注出口を開口させた中栓を設け、更にこの中栓外面と口頸部下部とを覆うキャップを装着したものが知られている（特許文献１）。     As a pouring container with an internal stopper, the upper part of the mouth and neck of the container body is a small outer diameter part, and the outer cylinder fitted to the small outer diameter part and the inner surface of the mouth and neck part are fitted in a liquid-tight manner. The inner cylinder is suspended from the outer periphery of the top plate, and an inner plug with an outlet opening is provided on the top plate portion inside the inner cylinder, and a cap that covers the outer surface of the inner plug and the lower part of the neck is attached. Known (Patent Document 1).

これに対して容器体と中栓とを分別回収し易くするために、中栓の外筒下部に下面開口の切欠きを穿設し、この切欠き内に指を入れて中栓の頂板を押し上げ、容器体の口頸部から中栓を取り外すことが可能に構成したものが提案されている（特許文献２）。
特開2001−158456号 特開2001−097425号 On the other hand, in order to make it easy to separate and collect the container body and the inner stopper, a notch with a lower surface opening is made in the lower part of the outer cylinder of the inner stopper, and a finger is put into the notch to attach the top plate of the inner stopper. There has been proposed a structure that can be pushed up and the inner plug can be removed from the mouth and neck of the container body (Patent Document 2).
JP 2001-158456 JP2001-097425

注出容器内の内容物が残り少なくなったときに中栓を外して口頸部から内容物を充填することが一般に行われているが、特許文献１の中栓では、その中栓の外面に指をかける適当な場所がないために中栓を外し難い。又、特許文献２の容器では、上述の切欠きに指をかけて中栓を取り外すことができるが、内容物の充填作業中に中栓を紛失してしまうおそれもあり、また取り外した中栓を置く場所がなくて困ることがあり、更に中栓を置く場所を忘れたり、或いは充填作業中に中栓を紛失するおそれがある。     It is common practice to remove the inner stopper and fill the contents from the mouth and neck when the content in the dispensing container is low. However, in the inner stopper of Patent Document 1, the inner stopper is placed on the outer surface of the inner stopper. It is difficult to remove the inner plug because there is no appropriate place to put a finger. Further, in the container of Patent Document 2, it is possible to remove the inner plug by putting a finger on the above-mentioned notch, but there is a possibility that the inner plug may be lost during the filling operation of the contents, and the removed inner plug If you do not have a place to put the plug, you may forget where to put the plug, or you may lose the plug during the filling operation.

又、特許文献１及び特許文献２のものでは、商品の流通段階で内容物を不正に抜き取る悪戯を阻止するためには、容器全体をシュリンクフィルムなどで閉塞する必要があった。     Moreover, in the thing of patent document 1 and patent document 2, in order to prevent the mischief which extracts a content illegally in the distribution stage of goods, it was necessary to block | close the whole container with a shrink film etc.

本発明は、中栓を口頸部に装着したままで充填作業を行うことができるように構成することで使い勝手の良く、更に封緘機能（バージンシール機構）を有する注出口付き中栓及び注出容器を提供することを目的とする。     INDUSTRIAL APPLICABILITY The present invention is easy to use by being configured so that the filling operation can be performed while the inner plug is attached to the mouth and neck, and further, the inner plug with a spout having a sealing function (virgin seal mechanism) and the dispensing The purpose is to provide a container.

第1の手段は、注出口付き中栓であり、容器の口頸部内外面への嵌合用の内筒と外筒とを頂板の外周部裏面から２重筒状に垂下させて、その内筒内周面よりも内側の頂板部分に注出口を開口した中栓において、上記内筒14外周面よりも外側の中栓上端部分に中栓後部を連結部22として残して、内筒14の周囲をＣ字状に囲む分離ライン24を穿設して、この分離ライン内方の中栓部分を内筒14付きの開閉板26とし、上記口頸部４への嵌合状態で開閉板26前部を引き上げると、少なくとも上記連結部22が撓むことで上記内筒14を口頸部４から引き抜くことができ、かつ該引抜き後に内筒14を口頸部４内へ液密に嵌合できる程度の可撓性及び柔軟性を有する材料で形成している。   The first means is an inner stopper with a spout, and an inner cylinder and an outer cylinder for fitting to the inner and outer surfaces of the mouth neck of the container are suspended in a double cylinder shape from the rear surface of the outer periphery of the top plate, In the inner plug having a spout opened in the top plate portion inside the inner peripheral surface of the cylinder, the inner plug rear portion is left as the connecting portion 22 in the upper end portion of the inner plug outside the outer peripheral surface of the inner cylinder 14, A separation line 24 that surrounds the periphery in a C-shape is formed, and an inner plug portion inside the separation line is used as an opening / closing plate 26 with an inner cylinder 14, and the opening / closing plate 26 is fitted to the neck portion 4. When the front part is pulled up, at least the connecting part 22 bends so that the inner cylinder 14 can be pulled out from the mouth-and-neck part 4, and the inner cylinder 14 is liquid-tightly fitted into the mouth-and-neck part 4 after the pulling out. It is made of a material having as much flexibility and softness as possible.

本手段では、容器体の口頸部から中栓を外すことなく、内筒を含む中栓上端部分で形成する開閉板を、分離ラインの破断により中栓他部から分離可能としたものである。   In this means, the opening / closing plate formed at the upper end portion of the inner plug including the inner cylinder can be separated from the other portion of the inner plug by breaking the separation line without removing the inner plug from the mouth / neck portion of the container body. .

「内筒」は、口頸部内面へ液密にシールするための栓筒である。この内筒は、後述の連結部を中心とした開閉板の回動により口頸部から引き抜き可能な長さに形成する。尚、本発明では、例えば第４、第５の手段で述べる如く、内筒の筒長を長くする以外の方法で口頸部のシール性を高めるための構造を提案している。   The “inner cylinder” is a plug cylinder for liquid-tight sealing to the inner surface of the mouth and neck. The inner cylinder is formed to have a length that can be pulled out from the mouth-neck portion by turning an opening / closing plate around a connecting portion described later. In the present invention, as described in the fourth and fifth means, for example, a structure for improving the sealing performance of the mouth and neck by a method other than increasing the cylinder length of the inner cylinder is proposed.

「外筒」は、口頸部外面へ取り付け、嵌着させるための嵌合筒である。その嵌合力は、少なくとも分離ラインを破断させるときの開閉板の引上げ力に対向できる程度の大きさであれば足りる。もっとも第３の手段で述べる如くバージンシール機能を担保させるときには、人の力で引き抜き不能に設ける。   The “outer cylinder” is a fitting cylinder for attaching and fitting to the outer surface of the mouth and neck. The fitting force is sufficient as long as it can be opposed to at least the pulling force of the opening / closing plate when breaking the separation line. However, when the virgin seal function is secured as described in the third means, it is provided so that it cannot be pulled out by human power.

「分離ライン」は、中栓の上部に穿設したスリット（切割り）のところどころに複数の破断可能な連結片を付設したものとしても良く、また、破断可能な肉薄線として形成しても良い。この分離ラインは、実施形態で後述するように頂板の外周部分又は頂板と外筒との接続部分に各部分の後部を残して形成することができる。   The “separation line” may be provided with a plurality of breakable connecting pieces at some slits (cuts) drilled in the upper part of the inner plug, or may be formed as a breakable thin line. . As will be described later in the embodiment, this separation line can be formed by leaving the rear portion of each portion at the outer peripheral portion of the top plate or the connecting portion between the top plate and the outer cylinder.

「連結部」は、開閉板後部と開閉板を除く中栓部分後部とを開閉板の回動可能に連結するヒンジの機能を有するものである。連結部の巾（左右巾）は上記開閉板の回動が可能な程度に短くかつヒンジの強度が確保できる程度に長く設ける。   The “connecting portion” has a function of a hinge for connecting the opening / closing plate rear portion and the inner plug portion rear portion excluding the opening / closing plate so that the opening / closing plate can rotate. The width of the connecting portion (left and right width) is short enough to allow the opening / closing plate to rotate and long enough to ensure the strength of the hinge.

「開閉板」は、容器体口頸部の上面開口を閉塞する閉塞板（或いは栓板）である。この開閉板は、分離ラインを破断した後も口頸部内面への内筒の嵌合により、口頸部上面を液密にシールするように設ける。   The “opening / closing plate” is a closing plate (or stopper plate) that closes the top opening of the container neck. The opening / closing plate is provided so that the upper surface of the mouth and neck portion is liquid-tightly sealed by fitting the inner tube to the inner surface of the mouth and neck portion even after the separation line is broken.

本手段に係る中栓は、上記連結部を中心として開閉板を回動させることができる程度に可撓性を有する材料で形成するものとし、更に上記開閉板の回動により口頸部内から中栓を引き抜き、かつ再嵌合させることができる程度の柔軟性を有するものとする。この中栓は、合成樹脂、例えばポリプロピレンやポリエチレンで形成すると良い。   The inner plug according to this means is formed of a material that is flexible so that the opening / closing plate can be rotated around the connecting portion, and further from inside the mouth and neck by the rotation of the opening / closing plate. It shall be flexible enough to pull out the inner plug and refit it. The inner plug is preferably formed of a synthetic resin such as polypropylene or polyethylene.

第２の手段は、上記第１の手段を有し、かつ上記外筒16の前壁上部を切り欠いて、この切欠き部28に上記分離ライン24を連続させるとともに、上記開閉板26前部から上記切欠き部28の上部分内へ操作片30を突設している。   The second means includes the first means, cuts out the upper portion of the front wall of the outer cylinder 16, and continues the separation line 24 to the cutout portion 28, and the front portion of the opening / closing plate 26. The operation piece 30 protrudes into the upper part of the notch 28 from above.

この手段では、開閉板を押し上げるため、或いは摘持するための操作片と、この操作片の押し上げなどを容易とするための切欠き部とを設けたものである。   This means is provided with an operating piece for pushing up or holding the open / close plate and a notch for facilitating pushing up of the operating piece.

第３の手段は、注出容器であり、上記第１の手段又は第２の手段である注出口付き中栓10の内筒14を、容器体２の口頸部４内面へ液密に嵌合し、かつ中栓10の外筒16を上記口頸部４外面へ嵌合するとともに引き抜き不能に係止させている。   The third means is a pouring container, and the inner tube 14 of the spout-equipped inner plug 10 as the first means or the second means is fitted in a liquid-tight manner on the inner surface of the mouth neck 4 of the container body 2. In addition, the outer cylinder 16 of the inner plug 10 is fitted to the outer surface of the mouth neck 4 and is locked so that it cannot be pulled out.

この手段は、上記中栓を注出容器に組み込んだものであり、少なくとも内容物を注出する際に中栓の分離ラインが外部に表れるようにして、不正開蓋の痕跡が残るようにしている。   This means incorporates the above-mentioned inner plug into the dispensing container, and at least when the contents are poured out, the separation line of the inner plug appears outside so that the trace of the unauthorized opening remains. Yes.

外筒の内面と口頸部の外面の一方には凸状の係合条を、他方には、凹条の係合条をそれぞれ形成して、これら両係合条の嵌合により外筒の抜出し不能に形成する。   A convex engagement strip is formed on one of the inner surface of the outer tube and the outer surface of the mouth and neck, and a concave engagement strip is formed on the other. It is formed so that it cannot be removed.

第４の手段は、第３の手段を有し、かつ上記中栓10は、上記内筒14外周面と外筒16内周面との間の頂板部分に、その頂板部分の後部を連結部22として残して、前端部で上記切欠き部28と連続する分離ライン24を形成してなる。   The fourth means includes the third means, and the inner plug 10 is connected to the top plate portion between the outer peripheral surface of the inner cylinder 14 and the inner peripheral surface of the outer cylinder 16 by connecting the rear portion of the top plate portion. The separation line 24 that is continuous with the notch portion 28 is formed at the front end portion.

本手段では、分離ラインを頂板上面に表れるようにしており、不正開蓋されたときの痕跡が上側から見てより明確に表れるようにしている。   In this means, the separation line appears on the top surface of the top plate so that the traces when the lid is opened illegally appear more clearly when viewed from above.

他方、液漏れ防止をより確実にするためには、分離ラインを破断する前の状態で分離ライン外側の頂板部分上面と分離ライン内方の開閉板の上面とを面一に形成することが望ましい。そうすると、分離ラインを破断させた後、分離ライン内方の空所に開閉板を押し込むことで口頸部内に内筒を嵌合させた場合に、開閉板の押込みが不充分で口頸部内に内筒が完全に嵌合されていないときには、分離ライン外側の頂板部分に比べて閉塞板が高くなり、上記嵌合が不完全であることが一見してわかるので、再び開閉板を下方へ押し込めば良い。   On the other hand, in order to further prevent liquid leakage, it is desirable to form the top surface of the top plate portion outside the separation line and the top surface of the opening / closing plate inside the separation line in a state before breaking the separation line. . Then, after breaking the separation line, when the inner cylinder is fitted into the mouth and neck by pushing the opening and closing plate into the space inside the separation line, the opening and closing of the opening and closing plate is insufficient. When the inner cylinder is not completely fitted inside, the closing plate is higher than the top plate portion outside the separation line, and it can be seen at a glance that the fitting is incomplete. Just push in.

第５の手段は、上記第３の手段を有し、かつ上記中栓10は、上記外筒16上端部と頂板12との間に、これら外筒16及び頂板12の後側部分を連結部22として残して、前端部で上記切欠き部28と連続する分離ライン24を形成してなり、更に、上記口頸部４内への内筒14の嵌着力で内筒14外周面よりも外側の頂板部分の裏面を口頸部４上端面へ液密に当接させることが可能に形成している。   The fifth means includes the third means, and the inner plug 10 is connected between the upper end portion of the outer cylinder 16 and the top plate 12 by connecting the rear portions of the outer cylinder 16 and the top plate 12 to each other. 22, a separation line 24 that is continuous with the notch portion 28 is formed at the front end portion, and is further outside the outer peripheral surface of the inner tube 14 due to the fitting force of the inner tube 14 into the mouth-and-neck portion 4. The back surface of the top plate portion is formed so that it can be brought into liquid-tight contact with the upper end surface of the neck 4.

本手段では、分離ラインが中栓の側面に表れるようにしている。又、口頸部内面と内筒外面との間のみでなく、内筒外方の頂板部分裏面と口頸部上端面との間で、各面を液密に当接してシール性を高めている。   In this means, the separation line appears on the side surface of the inner plug. In addition, not only between the inner surface of the mouth and neck and the outer surface of the inner cylinder, but also between each top surface of the top plate part outside the inner cylinder and the upper surface of the mouth and neck, liquid-tight contact is made to improve the sealing performance. Yes.

第１の手段に係る発明によれば、次の効果を奏する。
○開閉板26の前部を引き上げることで、容器体の口頸部から中栓10を外すことなく、口頸部の上面全体を開口させることができるので、便利であり、また中栓10を紛失するなどのおそれもない。
○分離ライン24を破断して開閉板26を引き上げた後に、その分離ライン内の空所に開閉板を入れることで内筒14を口頸部４内へ嵌合されるので、容易に再装着することができ、使い勝手が良い。 The invention according to the first means has the following effects.
○ By pulling up the front part of the opening and closing plate 26, the entire top surface of the mouth and neck can be opened without removing the inner plug 10 from the mouth and neck of the container body. There is no risk of loss.
○ After breaking the separation line 24 and pulling up the opening / closing plate 26, the opening / closing plate is inserted into the space in the separation line so that the inner cylinder 14 can be fitted into the mouth / neck 4 so that it can be easily remounted. Can be used and is easy to use.

第２の手段に係る発明によれば、開閉板26前部から上記切欠き部28の上部分内へ操作片30を突設したから、この操作片を用いて開閉板26を容易に開くことができる。   According to the invention relating to the second means, since the operating piece 30 protrudes from the front portion of the opening / closing plate 26 into the upper portion of the notch 28, the opening / closing plate 26 can be easily opened using this operating piece. Can do.

第３の手段に係る発明によれば、分離ライン24を中栓10上端部分に設けているので、不正開蓋の痕跡を目視することができ、バージンシール機能を発揮することができる。   According to the invention relating to the third means, since the separation line 24 is provided at the upper end portion of the inner plug 10, the trace of the unauthorized opening can be visually observed, and the virgin seal function can be exhibited.

第４の手段に係る発明によれば、次の効果を奏する。
○分離ライン24を頂板部分に形成したから、不正開蓋の痕跡が目立ち易く、バージンシール機能を高めることができる。
○頂板12の一部を連結部22としているから、後述の如く外筒16の後部を連結部22とした場合に比べて、開閉板の引上げによる連結部の撓み変形が容易に得られ、比較的柔軟性の少ない素材を用いても開閉板の開閉を確実に行うことができる。
○分離ライン24を破断させて内容物を充填させた後、この分離ライン内の空所に開閉板26を押し込んで口頸部４内に内筒14を液密に嵌合することとしたから、分離ライン外側の頂板部分で、前方側を除く開閉板26周縁部分で囲って他物との衝突を阻止することができ、この衝突により口頸部内への内筒14の嵌合が緩むことを防止できる。 The invention according to the fourth means has the following effects.
○ Since the separation line 24 is formed on the top plate portion, traces of unauthorized opening are easily noticeable, and the virgin seal function can be enhanced.
○ Because a part of the top plate 12 is a connecting part 22, compared with the case where the rear part of the outer cylinder 16 is a connecting part 22 as described later, the bending deformation of the connecting part by pulling up the opening / closing plate can be easily obtained and compared. The opening and closing plate can be reliably opened and closed even when using a material with less mechanical flexibility.
○ Because the separation line 24 was broken and filled with the contents, the opening / closing plate 26 was pushed into the space in the separation line, and the inner cylinder 14 was liquid-tightly fitted into the mouth / neck portion 4. The top plate portion outside the separation line can be surrounded by the periphery of the opening / closing plate 26 except for the front side to prevent collision with other objects, and this collision loosens the fitting of the inner cylinder 14 into the mouth and neck. Can be prevented.

第５の手段に係る発明によれば、次の効果を奏する。
○内筒14外周面よりも外側の頂板部分下面を、口頸部４の上端面に液密に当接したから、口頸部のシール性を更に高めることができる。
○分離ライン24が中栓の側面に表れるから、キャップをしない状態でも、分離ライン破断後の破断痕に埃などが付着し難く、また付着しても目立たない。 The invention according to the fifth means has the following effects.
○ Since the top plate portion lower surface outside the outer peripheral surface of the inner cylinder 14 is in liquid-tight contact with the upper end surface of the mouth-and-neck portion 4, the sealing performance of the mouth-and-neck portion can be further enhanced.
○ Since the separation line 24 appears on the side surface of the inner plug, even if the cap is not attached, dust or the like hardly adheres to the fracture marks after the separation line breaks, and even if it adheres, it is not noticeable.

図１から図３は、本発明の第１実施形態に係る注出容器を示している。   1 to 3 show a dispensing container according to the first embodiment of the present invention.

この注出容器は、容器体２と、中栓10と、キャップ34とで形成されている。   This dispensing container is formed of the container body 2, the inner stopper 10, and the cap 34.

容器体２は、胴部から肩部を介して口頸部４を起立している。この口頸部４の上端部は、図２に示す如く縮径部５を介して起立する小筒部６に形成しており、その小筒部６の下端部分には凹状の係合条８を周設している。上記小筒部６は、少なくとも後述の分離ラインよりも径方向に巾広の上端面を有する。   The container body 2 has the mouth-and-neck part 4 erected from the trunk part through the shoulder part. As shown in FIG. 2, the upper end portion of the neck portion 4 is formed in a small tubular portion 6 that stands up via a reduced diameter portion 5, and a concave engagement strip 8 is formed at the lower end portion of the small tubular portion 6. Around. The small tube portion 6 has an upper end surface that is wider in the radial direction than at least a separation line described later.

中栓10は、図２に示す如く上記口頸部４の上面を閉塞する平板形の頂板12の裏面外周部から内筒14及び外筒16を２重筒状に垂下してなる。上記内筒14は、外筒16よりもやや長く口頸部４内面に液密に嵌合されており、また、上記外筒16は、上記小外径部６の外面へ嵌合し、かつ外筒16の内面下端部に周設した凸状の係合条18を上記凹状係合条８内に固く嵌め込むことで抜出し不能に形成している。また、上記内筒14内方の頂板部分中央部には、注出口20を開口している。   As shown in FIG. 2, the inner plug 10 is formed by hanging an inner cylinder 14 and an outer cylinder 16 in a double cylinder shape from the outer peripheral portion of the back surface of a flat top plate 12 that closes the upper surface of the mouth neck 4. The inner cylinder 14 is slightly longer than the outer cylinder 16 and is fluid-tightly fitted to the inner surface of the mouth neck 4, and the outer cylinder 16 is fitted to the outer surface of the small outer diameter portion 6, and A convex engaging strip 18 provided around the lower end of the inner surface of the outer cylinder 16 is formed so as not to be pulled out by being firmly fitted into the concave engaging strip 8. Further, a spout 20 is opened at the center of the top plate portion inside the inner cylinder 14.

更にまた、図３及び図１に示す如く上記内筒14内周面と外筒16内周面との間の頂板部分には、この頂板部分後部を連結部22として残して、上方から見て略C字形の分離ライン24を形成している。図示の分離ライン24は頂板12に穿設したスリットのところどころに破断可能な連結片25を付設することで形成している。この分離ライン24の内方に存する頂板部分は、開閉板26として、図２に想像線で示す如く上記連結部22を中心として上後方への回動可能に形成している。又、この開閉板26は下面に内筒14を有しており、この内筒14が開閉板26の回動により口頸部４から引き抜かれるように構成している。また、図示例では、図３に示す如く上記分離ライン24を、内筒14外周面よりもやや外側に設けることで、開閉板26の外縁部分を上記小筒部６の上端面内縁部分に係止させている。もっとも分離ライン24の位置は適宜変更することができる。   Furthermore, as shown in FIG. 3 and FIG. 1, the top plate portion between the inner peripheral surface of the inner cylinder 14 and the inner peripheral surface of the outer cylinder 16 leaves the rear portion of the top plate portion as a connecting portion 22 and is viewed from above. A substantially C-shaped separation line 24 is formed. The illustrated separation line 24 is formed by attaching a breakable connecting piece 25 at some slits formed in the top plate 12. The top plate portion located inward of the separation line 24 is formed as an opening / closing plate 26 so as to be pivotable upward and backward about the connecting portion 22 as indicated by an imaginary line in FIG. The opening / closing plate 26 has an inner cylinder 14 on the lower surface, and the inner cylinder 14 is configured to be pulled out from the mouth / neck portion 4 by the rotation of the opening / closing plate 26. Also, in the illustrated example, as shown in FIG. 3, the separation line 24 is provided slightly outside the outer peripheral surface of the inner cylinder 14 so that the outer edge portion of the opening / closing plate 26 is related to the inner edge portion of the upper end surface of the small cylinder portion 6. It is stopped. However, the position of the separation line 24 can be changed as appropriate.

更に上記外筒16の前部上半は前方から見て矩形に切り欠いており、この切欠き部28の上端部を上記分離ライン24の前部に連続している。又、この切欠き部28の上半内には、上記開閉板26の前端部から突出した操作片30を挿入している。     Further, the upper half of the front portion of the outer cylinder 16 is cut out in a rectangular shape when viewed from the front, and the upper end portion of the cutout portion 28 is continuous with the front portion of the separation line 24. An operation piece 30 protruding from the front end of the opening / closing plate 26 is inserted into the upper half of the notch 28.

キャップ34は、有頂筒形であって、キャップ筒壁の内面を上記口頸部４の下部外周面に螺合させている。また、キャップ頂壁の裏面からは上記注出口20内へ液密に嵌合させるための嵌合筒（図示せず）を垂下している。尚、キャップ34は透明材料で形成すると、不正開蓋により分離ラインを破断させたときに、その破断痕がキャップを外すことなく判るので好適である。     The cap 34 has a top tube shape, and the inner surface of the cap tube wall is screwed to the lower outer peripheral surface of the mouth / neck portion 4. Further, a fitting cylinder (not shown) for liquid-tight fitting into the spout 20 is suspended from the back surface of the cap top wall. It is preferable that the cap 34 is made of a transparent material because when the separation line is broken by an unauthorized opening, the broken mark can be recognized without removing the cap.

上記構成において、本容器を使用するときには口頸部４からキャップ34を外して、注出口20から内容物を注出すれば良い。容器体２内の内容物が残り少なくなったときには、上記操作片30を指で上方へ押し上げ、そのまま押し上げた操作片30を摘んで上方に引き上げると、図２に示す如く分離ライン24が前方側から連結部22側へ順次破断して、この連結部を中心として開閉板26が後上方へ回動するとともに、上記口頸部４内から内筒14が引き抜かれ、口頸部４上面が開放される。この状態で別途用意した詰替用容器から新たに内容物を充填する。充填が完了したら、開閉板26を分離ライン24内の空所に戻すと上記内筒14が口頸部４内へ液密に嵌合される。この状態で内容物を注出するときには、容器を傾けて上記注出口20から注出することができる。   In the above configuration, when the container is used, the cap 34 may be removed from the neck 4 and the contents may be poured out from the spout 20.
