Description

本発明は、口栓を備えた柔軟な容れ物、および該口栓に関する。   The present invention relates to a flexible container provided with a plug and the plug.

フィルム包装袋やプラスチック容器のような柔軟な容れ物に酢やしょう油などの液体調味料を収容したものが市場に多数供給されている。このような容れ物において、容れ物内への異物混入や液体調味料の品質低下を防止するため、注出口には一般にキャップが備えられている。   Many products containing liquid seasonings such as vinegar and soy sauce in flexible containers such as film packaging bags and plastic containers are supplied to the market. In such a container, a cap is generally provided at the spout in order to prevent foreign matter from entering the container and deterioration of the quality of the liquid seasoning.

このような柔軟な容れ物では注出口から液体調味料を注ぎ出すとき、キャップを取り外した後、注出口を下側に向けるか、または容れ物を外側から加圧することで液体調味料が出る。特に、注出口が比較的小さい場合は容れ物の胴を押して液体調味料を出すことになる。   In such a flexible container, when the liquid seasoning is poured out from the spout, the liquid seasoning comes out by removing the cap and then directing the spout downward or pressurizing the container from the outside. In particular, when the spout is relatively small, the liquid seasoning is dispensed by pushing the barrel of the container.

液体調味料の注出時は注出口を閉じられないので、容れ物内に空気が入り込むことがある。この空気の影響で液体調味料が経時的に劣化して製造直後の風味を損なってしまう。   Since the spout cannot be closed when the liquid seasoning is poured out, air may enter the container. Under the influence of this air, the liquid seasoning deteriorates with time, and the flavor immediately after production is impaired.

また、注出口が比較的小さい容れ物において中に空気が入った状態で容れ物の胴を押して液体調味料を注出させる場合、液体調味料の残量が少なくなってくると、液体調味料を出しにくくなり、場合によって注出口から液体調味料が空気と一緒に出て飛び散る危険性もある。   In addition, when a liquid seasoning is poured out by pushing the drum of the container in a state where air is contained in a container having a relatively small spout, the liquid seasoning is reduced when the remaining amount of the liquid seasoning decreases. In some cases, there is a risk that the liquid seasoning may come out together with the air from the spout and scatter.

そこで、特許文献１〜３に開示されるように、通常状態では容れ物の口部が弁体で閉じられていて、容れ物が外側から加圧された時に内容物が弁体を動かして口部が開き、内容物が吐出されるようにした発明が提案されている。   Therefore, as disclosed in Patent Documents 1 to 3, in a normal state, the mouth portion of the container is closed with a valve body, and when the container is pressurized from the outside, the contents move the valve body to open the mouth. An invention has been proposed in which the portion is opened and the contents are discharged.

特許文献１及び２に開示される口栓では、チューブ容器の口部の内側に弁部材が移動可能に配置され、チューブ容器内が減圧状態のときは弁部材の側面部が筒状体の内壁に着座し、チューブ容器内が加圧状態のときは弁部材の側面部が口部の内壁から離間するようになっている。ところが、この口栓構造では弁部材自体が自己復帰機能を備えていないため、チューブ容器内が減圧状態にならない限り、弁部材の側部が口部の内壁から離間したままで口部と弁部材の間の流路は閉じられない。したがって、チューブ容器内に空気が入り込みやすいと考えられる。   In the stoppers disclosed in Patent Documents 1 and 2, the valve member is movably disposed inside the mouth portion of the tube container, and when the inside of the tube container is in a decompressed state, the side surface portion of the valve member is the inner wall of the cylindrical body. When the inside of the tube container is in a pressurized state, the side surface portion of the valve member is separated from the inner wall of the mouth portion. However, in this plug structure, since the valve member itself does not have a self-return function, unless the inside of the tube container is in a reduced pressure state, the side portion of the valve member remains separated from the inner wall of the mouth portion and the valve member. The flow path between is not closed. Therefore, it is considered that air easily enters the tube container.

また、特許文献３に開示される口栓では、容器の口部の内側に柱状部が形成されつつ口部の内壁と柱状部の外壁の間に流路孔が形成され、さらに口部の開口端に注出筒が接合され、この注出筒は柱状部を覆いつつ、柱状部の側部に形成された弾性シール弁と接触している。この口栓構造によると、通常は柱状部と注出筒の間が弾性シール弁で閉じられているが、容器の胴を押した時だけ容器内の内容物が弾性シール弁を退かして、柱状部と注出筒の間を通過できるようになっている。しかしながら、この口栓構造では弾性シール弁が注出筒の内周面全体に亘って当接するように作製する必要があり、製作が困難で、弾性シール弁のシール性もばらつきやすい。また内容物の吐出性の調整も容易ではない。   Further, in the spigot disclosed in Patent Document 3, a channel hole is formed between the inner wall of the mouth portion and the outer wall of the pillar portion while the columnar portion is formed inside the mouth portion of the container, and the opening of the mouth portion is further formed. A pouring tube is joined to the end, and the pouring tube is in contact with an elastic seal valve formed on the side of the columnar portion while covering the columnar portion. According to this plug structure, the space between the columnar part and the dispensing cylinder is normally closed by an elastic seal valve, but the contents in the container retract the elastic seal valve only when the container body is pushed. It is possible to pass between the columnar part and the dispensing cylinder. However, in this spigot structure, it is necessary to make the elastic seal valve so as to abut on the entire inner peripheral surface of the dispensing cylinder, making it difficult to manufacture, and the sealing performance of the elastic seal valve tends to vary. Moreover, it is not easy to adjust the discharge property of the contents.

そこで本発明は上述した背景技術の課題に鑑み、容れ物内に空気が入り込みにくくなり、かつ、製作性が良い口栓および、該口栓を備えた柔軟な容れ物を提供することを目的とする。   Accordingly, in view of the above-described problems of the background art, the present invention has an object to provide a mouth plug that is less likely to allow air to enter the container and has good manufacturability, and a flexible container including the mouth plug. To do.

本発明の一態様は柔軟な容れ物の口部として用いられる口栓を提供する。この口栓は、筒状の口栓本体と、自己復元力を持つ弁体と、注出筒と、を備える。口栓本体は上端が閉じられ下端が開口した筒部を有する。該筒部の側面には、液体を排出する第一の開口が形成されている。弁体は両端が開口した筒形状を成し、口栓本体の筒部の側面に被せられている。さらに、弁体の下端部が口栓本体に固着され、該下端部を除いた非固着部位が第一の開口を覆っている。注出筒は弁体を覆うように形成され、該注出筒の上端部には、液体を注ぎ出す第二の開口が形成されている。注出筒の下端部は口栓本体と固着され、注出筒の側壁部は弁体の非固着部位から離れて形成されている。   One aspect of the present invention provides a plug used as the mouth of a flexible container. The plug includes a cylindrical plug body, a valve body having a self-restoring force, and a dispensing cylinder. The spigot body has a cylindrical portion whose upper end is closed and whose lower end is open. A first opening for discharging the liquid is formed on the side surface of the cylindrical portion. The valve body has a cylindrical shape with both ends opened, and is covered on the side surface of the cylindrical portion of the plug body. Further, the lower end portion of the valve body is fixed to the plug body, and the non-fixed portion excluding the lower end portion covers the first opening. The dispensing cylinder is formed so as to cover the valve body, and a second opening for pouring the liquid is formed at the upper end of the dispensing cylinder. The lower end portion of the dispensing tube is fixed to the plug body, and the side wall portion of the dispensing tube is formed away from the non-fixed portion of the valve body.

また本発明の別の態様は、上記の態様による口栓を備えた柔軟な容れ物を提供する。   Another aspect of the present invention provides a flexible container with a spigot according to the above aspect.

本発明によれば、柔軟な容れ物内を加圧することで、容れ物内の液体を口栓本体の側面の第一の開口から弁体を押しのけて排出することができる。また容器内を加圧しないときは、弁体が自己復元力によって元の形状に戻って口栓本体の側面の開口部を塞ぐため、液体を注ぎ出す第二の開口を塞ぐキャップ等が無くても、容れ物内に空気が入り込まない。このため、容れ物内の液体が空気の影響で劣化することが無くなる。   According to the present invention, by pressurizing the inside of the flexible container, the liquid in the container can be discharged by pushing the valve body from the first opening on the side surface of the plug body. Also, when the inside of the container is not pressurized, the valve body returns to its original shape by the self-restoring force and closes the opening on the side surface of the plug body, so there is no cap or the like that closes the second opening from which liquid is poured. However, air does not enter the container. For this reason, the liquid in the container is not deteriorated by the influence of air.

以下、本発明の実施の形態について図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は本発明の一実施形態によるキャップ付き口栓の、その中心軸に沿って切断した断面図を示している。本実施形態のキャップ付き口栓はフィルム包装袋やプラスチック容器のような柔軟な容れ物の口部として用いられることが好ましい。   FIG. 1 shows a cross-sectional view of a cap with a cap according to an embodiment of the present invention, cut along its central axis. The cap with cap of this embodiment is preferably used as a mouth part of a flexible container such as a film packaging bag or a plastic container.

図１を参照すると、このキャップ付き口栓は、筒部１ａを持つ口栓本体１と、口栓本体１の側面に固着された筒状の弁体２と、弁体２を覆いつつ口栓本体１と接合された注出筒３と、注出筒３に螺合して取り付けられたキャップ４とを備える。   Referring to FIG. 1, this cap-attached plug includes a plug body 1 having a cylindrical portion 1 a, a tubular valve body 2 fixed to the side surface of the plug body 1, and a plug that covers the valve body 2. A pouring tube 3 joined to the main body 1 and a cap 4 screwed onto the pouring tube 3 are provided.

さらに詳述すると、口栓本体１は上端が閉じられ下端が開口した筒部１ａを有する。筒部１ａの側面には、口栓本体１の下端側より上方へ流入してきた液体（例えばしょうゆ等の液体調味料）を排出する第一の開口１ｂが形成されている。なお、第一の開口１ｂは一つ又は複数形成されていてよい。開口１ｂを複数形成する場合は同じ大きさの開口を等間隔に配置することが望ましい。口栓本体１の材質にはポリエチレンが好ましい。   More specifically, the plug body 1 has a cylindrical portion 1a having an upper end closed and a lower end opened. A first opening 1b for discharging liquid (for example, liquid seasoning such as soy sauce) that flows upward from the lower end side of the plug body 1 is formed on the side surface of the cylindrical portion 1a. One or a plurality of first openings 1b may be formed. When forming a plurality of openings 1b, it is desirable to arrange openings of the same size at equal intervals. The material of the plug body 1 is preferably polyethylene.

弁体２はシリコーンゴムなどのエラストマーからなる柔軟な部品であり、両端が開口する円筒形からなる。弁体２は口栓本体１の筒部１ａの側面に被せられて、弁体２の下端部が口栓本体１の筒部１ａと固着されている。一方、筒部１ａと固着されていない弁体２の部位（以下、非固着部位と呼ぶ）は筒部１ａの側面の開口１ｂを覆うように配置されているが、口栓本体１の側面に対して自由に変形可能である。また、弁体２はエラストマーからなるため、自己復元力を持つ。   The valve body 2 is a flexible part made of an elastomer such as silicone rubber, and has a cylindrical shape with both ends open. The valve body 2 is placed on the side surface of the tube portion 1 a of the plug body 1, and the lower end portion of the valve body 2 is fixed to the tube portion 1 a of the plug body 1. On the other hand, the part of the valve body 2 that is not fixed to the cylinder part 1a (hereinafter referred to as a non-adhered part) is arranged so as to cover the opening 1b on the side surface of the cylinder part 1a. On the other hand, it can be freely deformed. Further, since the valve body 2 is made of an elastomer, it has a self-restoring force.

さらに、筒部１ａの側面と弁体２の非固着部位とは所定のクリアランスＣＬを開けてある。このため、筒部１ａは、例えば図２に示すように、上端が閉じられた円筒の側面の一部を円筒上端から下端の近傍まで平坦面１ｃにした形状を有し、この平坦面１ｃに開口１ｂが形成されている。平坦面１ｃを設ける箇所は、図２に示される筒部１ａの側面のように、相対する２つの箇所になくてもよく、少なくとも１箇所にあればよい。このように形成された筒部１ａの側面に、前記の円筒の外径と同じかそれ以下の内径を持つ弁体２が被せられる。これにより、筒部１ａの側面の平坦部１ｃと弁体２の非固着部位との間にクリアランスＣＬが形成されている。   Further, a predetermined clearance CL is opened between the side surface of the cylindrical portion 1a and the non-fixed portion of the valve body 2. For this reason, as shown in FIG. 2, for example, the cylindrical portion 1a has a shape in which a part of the side surface of the cylinder whose upper end is closed is a flat surface 1c from the upper end of the cylinder to the vicinity of the lower end. An opening 1b is formed. The place where the flat surface 1c is provided does not have to be in two opposite places like the side face of the cylindrical portion 1a shown in FIG. 2, and may be in at least one place. A valve body 2 having an inner diameter equal to or smaller than the outer diameter of the cylinder is placed on the side surface of the cylindrical portion 1a formed in this manner. Thereby, a clearance CL is formed between the flat portion 1c on the side surface of the cylindrical portion 1a and the non-fixed portion of the valve body 2.

またクリアランスＣＬは筒部１ａの全周に亘って形成されていてもよい。この場合、筒部１ａは、弁体２の非固着部位に対応する部位の外径が弁体２の下端部に対応する部位の外径と比べて縮小されているものである（不図示）。   The clearance CL may be formed over the entire circumference of the cylindrical portion 1a. In this case, the cylindrical part 1a is such that the outer diameter of the part corresponding to the non-fixed part of the valve body 2 is reduced compared to the outer diameter of the part corresponding to the lower end part of the valve body 2 (not shown). .

こうした２タイプの筒部１ａで設けられるクリアランスＣＬは、弁体２が加圧されていない状態のときに液体調味料などの液体を表面張力で留められるクリアランスであることが望ましい。   The clearance CL provided by the two types of cylindrical portions 1a is desirably a clearance that can hold a liquid such as a liquid seasoning with surface tension when the valve body 2 is not pressurized.

さらに、注出筒３は筒形状に形成されている。注出筒３の材質にはポリエチレンが好ましい。注出筒３の側壁部は弁体２の非固着部から離れて弁体２を覆うように形成され、かつ、口栓本体１の下端部と固着されている。注出筒３の上端面には、液体調味料などの液体を注ぎ出す第二の開口３ａがトランペット形に形成されている。   Further, the dispensing cylinder 3 is formed in a cylindrical shape. The material of the dispensing tube 3 is preferably polyethylene. The side wall portion of the dispensing cylinder 3 is formed so as to cover the valve body 2 away from the non-fixed portion of the valve body 2 and is fixed to the lower end portion of the spigot body 1. A second opening 3 a for pouring a liquid such as a liquid seasoning is formed in the upper end surface of the dispensing cylinder 3 in a trumpet shape.

注出筒３の側壁部の外側面には雄ねじ３ｂが設けられ、注出筒３の外側からスクリュー式のキャップ４が装着されている。キャップ４の材質にはポリエチレンが好ましい。   A male screw 3 b is provided on the outer surface of the side wall portion of the dispensing cylinder 3, and a screw-type cap 4 is attached from the outside of the dispensing cylinder 3. The material of the cap 4 is preferably polyethylene.

キャップ４の内側には、第二の開口３ａを閉栓するための突起４ａが形成されており、キャップ４の注出筒３への装着により突起４ａが第二の開口３ａに進入して第二の開口３ａを塞ぐ。なお、本実施形態のキャップ４は注出筒３からねじり切って開封するタイプのスクリューキャップであるが、本発明はこれに限定されない。   A protrusion 4a for closing the second opening 3a is formed on the inner side of the cap 4, and the protrusion 4a enters the second opening 3a when the cap 4 is attached to the dispensing cylinder 3, and the second opening 3a is inserted into the second opening 3a. The opening 3a is closed. In addition, although the cap 4 of this embodiment is a screw cap of the type twisted and opened from the extraction | pouring cylinder 3, this invention is not limited to this.

図３は図１に示したキャップ付き口栓の構成部品の模式的斜視図である。但し、キャップ４は図示されていない。この図から分かるように、口栓本体１の筒部の外側に弁体２、注出筒３およびキャップ４をこの順に被せるように、口栓本体１と弁体２と注出筒３とキャップ４を組み合わせて互いに接合することで、図１に示したようなキャップ付き口栓が出来上がる。   3 is a schematic perspective view of components of the cap with cap shown in FIG. However, the cap 4 is not illustrated. As can be seen from this figure, the plug body 1, the valve body 2, the extraction cylinder 3, and the cap so that the valve body 2, the extraction cylinder 3, and the cap 4 are covered in this order on the outside of the cylindrical portion of the plug body 1 By combining 4 and joining each other, a cap with a cap as shown in FIG. 1 is completed.

図４は図１に示したキャップ付き口栓をフィルム包装袋の口部として装着した形態例を示す。図１及び図３に示されるように注出筒３の下端部は横に張り出した形状（張り出し部３ｃ）を有する。この張り出し部３ｃがフィルム包装袋５の上端又は下端のフィルム部間に挟み込まれ、熱融着方式により、張り出し部３ｃの両側面と各フィルム部が気密に接着されている。   FIG. 4 shows an embodiment in which the cap with cap shown in FIG. 1 is mounted as a mouth portion of a film packaging bag. As shown in FIGS. 1 and 3, the lower end portion of the dispensing tube 3 has a shape projecting sideways (projecting portion 3 c). This overhanging portion 3c is sandwiched between the film portions at the upper end or the lower end of the film packaging bag 5, and both side surfaces of the overhanging portion 3c and each film portion are hermetically bonded by a heat fusion method.

なお、本発明のキャップ付き口栓を取り付けられる容れ物は上記のフィルム包装袋５に限られず、プラスチック容器のような柔軟な容れ物であればどんな物でもよい。   The container to which the cap with cap of the present invention can be attached is not limited to the above-described film packaging bag 5 and may be any flexible container such as a plastic container.

次に、本実施形態の口栓による液体の注ぎ出し方法について説明する。   Next, the liquid pouring method using the spigot of this embodiment will be described.

上述のようにキャップ付き口栓が装着されたフィルム包装袋５では、図５に示すように袋の胴が手で加圧されると、袋内に収容されている液体調味料などの液体が注ぎ出される。   In the film packaging bag 5 with the cap plug as described above, when the bag body is pressurized by hand as shown in FIG. 5, liquid such as liquid seasoning contained in the bag is discharged. Poured out.

具体的には、注出筒３からキャップ４を取り外してフィルム包装袋５の胴を押すと、袋内圧が増加する。これにより、図１中の矢印Ｆで示すように、液体調味料などの液体が口栓本体１の内側を通って第一の開口１ｂから排出される。   Specifically, when the cap 4 is removed from the dispensing tube 3 and the body of the film packaging bag 5 is pushed, the bag internal pressure increases. Thereby, as shown by the arrow F in FIG. 1, liquids, such as a liquid seasoning, pass through the inner side of the plug main body 1, and are discharged | emitted from the 1st opening 1b.

第一の開口１ｂから排出された液体は弁体２と筒部１ａの間のクリアランスＣＬを拡げるように弁体２を変形させて、弁体２と筒部１ａの間を通過し、第二の開口３ａから注ぎ出される。   The liquid discharged from the first opening 1b deforms the valve body 2 so as to widen the clearance CL between the valve body 2 and the cylinder portion 1a, passes between the valve body 2 and the cylinder portion 1a, and passes through the second It is poured out from the opening 3a.

その後、フィルム包装袋５の胴を押すのを止めると、弁体２の非固着部位が自己復元力で元の形状に戻り、筒部１ａの第一の開口１ｂを覆った状態になる。このとき、弁体２の非固着部材と筒部１ａの開口１ｂを含む面部との間にクリアランスＣＬがあるが、このクリアランスＣＬには液体が表面張力で留まっている。このため、空気がクリアランスＣＬに侵入できず、開口１ｂから筒部１ａの内側へ空気は入り込めない。したがって、袋内の液体調味料について製造直後の風味を維持することが出来る。   Thereafter, when the pressing of the body of the film packaging bag 5 is stopped, the non-fixed portion of the valve body 2 returns to its original shape by the self-restoring force, and the first opening 1b of the cylindrical portion 1a is covered. At this time, there is a clearance CL between the non-fixed member of the valve body 2 and the surface portion including the opening 1b of the cylindrical portion 1a, but the liquid remains in the clearance CL with surface tension. For this reason, air cannot enter the clearance CL, and air cannot enter the inside of the cylindrical portion 1a from the opening 1b. Therefore, the flavor immediately after manufacture can be maintained about the liquid seasoning in a bag.

上記のような弁体２の機能を良好に実現するには、シリコーンゴムからなる弁体２の肉厚は０．１〜０．３［ｍｍ］程度で、好ましくは０．２［ｍｍ］が良い。また、筒部１ａと弁体２との隙間寸法は、クリアランスＣＬを設けるための平坦面１ｃの所を除いてゼロ以下であり、かつ、平坦面１ｃの所の初めのクリアランスＣＬは０［ｍｍ］＜ＣＬ＜０．２［ｍｍ］程度であることが実験により好ましかった。   In order to satisfactorily realize the function of the valve body 2 as described above, the thickness of the valve body 2 made of silicone rubber is about 0.1 to 0.3 [mm], preferably 0.2 [mm]. good. The clearance between the cylindrical portion 1a and the valve body 2 is zero or less except for the flat surface 1c for providing the clearance CL, and the initial clearance CL at the flat surface 1c is 0 [mm. ] It was preferred by experiments that <CL <0.2 [mm].

このクリアランスＣＬの範囲について言うと、仮に弁体２の非固着部材を筒部１ａの開口１ｂを含む平坦部１ｃに密着させれば袋内への空気の侵入を十分に防止することができる。しかし、この場合クリアランスＣＬはゼロ以下であるため、弁体２と筒部１ａの間を液体が通過できるように弁体２を押し伸ばしてクリアランスＣＬを拡げるのに袋に過大な押し圧が必要になる。この結果、液体が袋の口から飛び出すように出て注ぎづらい。つまり、液体の吐出性が良くない。一方、クリアランスＣＬが大き過ぎると、袋の胴を押すのを止めて弁体２が元の形状に戻ってもクリアランスＣＬに液体を表面張力で留まることができず、袋内への空気の侵入を許してしまう。このため、上記のように０［ｍｍ］＜ＣＬ＜０．１［ｍｍ］程度の範囲で初めのクリアランスＣＬを設けることが望ましい。   Speaking of the range of the clearance CL, if the non-fixed member of the valve body 2 is brought into close contact with the flat portion 1c including the opening 1b of the cylindrical portion 1a, the intrusion of air into the bag can be sufficiently prevented. However, in this case, since the clearance CL is less than or equal to zero, an excessive pressing force is required on the bag in order to extend the clearance CL by extending the valve 2 so that the liquid can pass between the valve 2 and the cylindrical portion 1a. become. As a result, it is difficult for the liquid to come out from the bag mouth and to be poured. That is, the liquid discharge property is not good. On the other hand, if the clearance CL is too large, the liquid cannot remain in the clearance CL due to surface tension even if the body of the bag is stopped and the valve body 2 returns to its original shape, and air enters the bag. I will forgive you. For this reason, it is desirable to provide the first clearance CL in the range of about 0 [mm] <CL <0.1 [mm] as described above.

さらに、上記のクリアランスＣＬを袋内の液体の性状に応じて調整すれば、その液体に最適な吐出性とシール性を備えた柔軟な容れ物を提供することができる。   Furthermore, if the clearance CL is adjusted in accordance with the properties of the liquid in the bag, a flexible container having an optimal discharge property and sealing property for the liquid can be provided.

Moreover, even if the cylinder part 1a is a form different from the form of FIG. 2, the flexible container provided with the cap with a cap provided with the optimal discharge property and sealability can be provided. FIG. 6 shows a perspective view of another embodiment of the cylindrical portion 1a.

別の形態の筒部１ａは、図６に示すように、上端が閉じられた円筒の側面の一部を円筒上端から下端の近傍まで平坦面１ｃにした形状を有し、この平坦面１ｃを除いた円筒の曲面に開口１ｂが形成されている。平坦面１ｃを設ける箇所は少なくとも１箇所にあればよいが、より好ましくは、図６に示される筒部１ａの側面のように、相対する２つの箇所に平坦面１ｃを設けるのが良い。図６では、平坦面１ｃを除く円筒の相対する２つの曲面にそれぞれ開口１ｂが形成されている。   As shown in FIG. 6, the cylindrical portion 1a of another form has a shape in which a part of a side surface of a cylinder whose upper end is closed is a flat surface 1c from the upper end of the cylinder to the vicinity of the lower end. An opening 1b is formed in the curved surface of the removed cylinder. The flat surface 1c may be provided at least at one location, but more preferably, the flat surface 1c may be provided at two opposing locations such as the side surface of the cylindrical portion 1a shown in FIG. In FIG. 6, openings 1b are respectively formed on two opposing curved surfaces of the cylinder excluding the flat surface 1c.

このように形成された筒部１ａの側面に、前記の円筒の外径と同じか僅かに大きい内径を持つ弁体２が被せられて、筒部１ａの側面の平坦部１ｃと弁体２の非固着部位との間にクリアランスＣＬが形成されている（図７（ａ）参照）。   The side surface of the cylindrical portion 1a formed in this way is covered with a valve body 2 having an inner diameter that is the same as or slightly larger than the outer diameter of the cylinder, and the flat portion 1c on the side surface of the cylindrical portion 1a and the valve body 2 A clearance CL is formed between the non-adhered portion (see FIG. 7A).

このような形態以外は、図１〜図５を参照して前述したキャップ付き口栓と同じである。   Except such a form, it is the same as the cap with cap mentioned above with reference to FIGS.

次に、本実施形態の口栓による液体の注ぎ出し方法について説明する。   Next, the liquid pouring method using the spigot of this embodiment will be described.

注出筒３からキャップ４を取り外してフィルム包装袋５の胴を押すと、袋内圧が増加する。これにより、液体調味料などの液体が口栓本体１の内側を通って第一の開口１ｂから出ようとする。開口１ｂを通過した液体は開口１ｂに対応する弁体２の部位を押す。このとき、弁体２は自身の周長を保とうとして、開口１ｂに対応する弁体２の部位が筒部１ａの側面から離れた分、平坦部１ｃの所のクリアランスＣＬが狭くするように変形する（図７（ｂ）参照）。これにより、弁体２と筒部１ａの間に液体Ｓの通路ができ、該通路を通過した液体Ｓは第二の開口３ａから注ぎ出される。   When the cap 4 is removed from the dispensing tube 3 and the body of the film packaging bag 5 is pushed, the pressure inside the bag increases. Thereby, liquids, such as a liquid seasoning, try to go out from the 1st opening 1b through the inner side of the plug main body 1. FIG. The liquid that has passed through the opening 1b pushes the part of the valve body 2 corresponding to the opening 1b. At this time, the valve body 2 tries to maintain its peripheral length so that the clearance CL at the flat portion 1c is narrowed by the amount of the portion of the valve body 2 corresponding to the opening 1b away from the side surface of the cylindrical portion 1a. Deformation (see FIG. 7B). As a result, a passage for the liquid S is formed between the valve body 2 and the cylindrical portion 1a, and the liquid S that has passed through the passage is poured out from the second opening 3a.

その後、フィルム包装袋５の胴を押すのを止めると、弁体２の非固着部位が自己復元力で元の形状に戻り、筒部１ａの第一の開口１ｂを覆った状態になる。このとき、弁体２は筒部１ａの第一の開口１ｂを含む面部と接して、第一の開口１ｂを塞いでいる。このため、開口１ｂから筒部１ａの内側へ空気は入り込めない。したがって、袋内の液体調味料について製造直後の風味を維持することが出来る。   Thereafter, when the pressing of the body of the film packaging bag 5 is stopped, the non-fixed portion of the valve body 2 returns to its original shape by the self-restoring force, and the first opening 1b of the cylindrical portion 1a is covered. At this time, the valve body 2 is in contact with the surface portion including the first opening 1b of the cylindrical portion 1a and closes the first opening 1b. For this reason, air cannot enter into the inside of the cylinder part 1a from the opening 1b. Therefore, the flavor immediately after manufacture can be maintained about the liquid seasoning in a bag.

上記のような弁体２の機能を良好に実現するには、シリコーンゴムからなる弁体２の肉厚は０．１〜０．３［ｍｍ］程度で、好ましくは０．２［ｍｍ］が良い。また、筒部１ａと弁体２との隙間寸法Ｘ（図７（ａ）参照）は、クリアランスＣＬを設けるための平坦面１ｃの所を除いて、０＜Ｘ＜０．２［ｍｍ］程度であり、かつ、初めのクリアランスＣＬは０．５［ｍｍ］＜ＣＬ＜２．０［ｍｍ］程度であることが実験により好ましかった。   In order to satisfactorily realize the function of the valve body 2 as described above, the thickness of the valve body 2 made of silicone rubber is about 0.1 to 0.3 [mm], preferably 0.2 [mm]. good. The clearance dimension X (see FIG. 7A) between the cylinder portion 1a and the valve body 2 is about 0 <X <0.2 [mm] except for the flat surface 1c for providing the clearance CL. In addition, the initial clearance CL was preferably about 0.5 [mm] <CL <2.0 [mm] by experiments.

平坦面１ｃの所を除いた筒部１ａと弁体２の間の隙間寸法について言うと、弁体２の非固着部材を筒部１ａの開口１ｂを含む面部に密着させれば袋内への空気の侵入を十分に防止することができる。しかし、この場合、開口１からの液体の圧力で弁体２を押し伸ばして弁体２と筒部１ａの間に液体の通路を確保する必要があり、袋の押し圧が過大になる。この結果、液体が袋の口から飛び出すように出て注ぎづらい。つまり、液体の吐出性が良くない。一方、弁体２の非固着部材と、筒部１ａの開口１ｂを含む面部との隙間が大き過ぎると、袋の胴を押すのを止めて弁体２が元の形状に戻っても、その隙間に液体を表面張力で留まることができず、袋内への空気の侵入を許してしまう。このため、平坦面１ｃの所を除いた筒部１ａと弁体２の間の隙間寸法Ｘは０＜Ｘ＜０．２［ｍｍ］程度の範囲であることが望ましい。   Speaking of the gap size between the cylindrical part 1a and the valve body 2 except for the flat surface 1c, if the non-fixed member of the valve body 2 is brought into close contact with the surface part including the opening 1b of the cylindrical part 1a, Intrusion of air can be sufficiently prevented. However, in this case, it is necessary to stretch the valve body 2 with the pressure of the liquid from the opening 1 to secure a liquid passage between the valve body 2 and the cylinder portion 1a, and the pressing pressure of the bag becomes excessive. As a result, it is difficult for the liquid to come out from the bag mouth and to be poured. That is, the liquid discharge property is not good. On the other hand, if the gap between the non-adhering member of the valve body 2 and the surface portion including the opening 1b of the cylindrical portion 1a is too large, even if the valve body 2 returns to its original shape by stopping pressing the bag body, The liquid cannot stay in the gap due to the surface tension, allowing air to enter the bag. For this reason, it is desirable that the gap dimension X between the cylindrical portion 1a and the valve body 2 excluding the flat surface 1c is in a range of about 0 <X <0.2 [mm].

さらに、平坦部１ｃの所のクリアランスＣＬの範囲については、その液体の排出時に弁体２の周長を保ちながら、開口１ｂに対応する弁体２の部位を、筒部１ａの開口１ｂを含む面部から遠ざけることが容易となる寸法範囲であればよい。初めのクリアランスＣＬが０．５［ｍｍ］＜ＣＬ＜２．０［ｍｍ］程度であると、弁体２に対して大きな液体圧力を与えなくても液体の通路が確保できた。   Further, regarding the range of the clearance CL at the flat portion 1c, the portion of the valve body 2 corresponding to the opening 1b is included in the opening 1b of the cylindrical portion 1a while maintaining the circumferential length of the valve body 2 when the liquid is discharged. It may be a dimension range that makes it easy to move away from the surface portion. When the initial clearance CL is about 0.5 [mm] <CL <2.0 [mm], a liquid passage can be secured without applying a large liquid pressure to the valve body 2.

上記の隙間寸法Ｘ及びクリアリンスＣＬを袋内の液体の性状に応じて調整すれば、その液体に最適な吐出性とシール性を備えた柔軟な容れ物を提供することができる。   If the gap dimension X and the clear rinse CL are adjusted according to the properties of the liquid in the bag, a flexible container having optimum discharge performance and sealing performance for the liquid can be provided.
