Description

本発明は、容器本体の口部に取り付けられて内容物を外部に吐出する吐出キャップに関する。   The present invention relates to a discharge cap that is attached to a mouth portion of a container body and discharges contents to the outside.

従来、スクイズ変形可能な外側容器と外側容器に対して変形可能な内側容器を積層した容器本体と、容器本体に装着された吐出キャップと、を備え、外気を吸引することなく内容物を吐出可能とした吐出容器が提案されている(例えば、特許文献1参照)。
この吐出容器では、内側容器の内側と吐出容器の外部とを連通する連通開口に内側容器への内容物の逆流及び外気の流入を防止する弁体が設けられている。内容物を吐出させる場合には、容器本体を傾けた状態でスクイズ変形させ、内側容器から流出しようとする内容物により弁体を連通開口から離間させることによって連通開口と吐出容器の外部とを連通させる。そして、吐出キャップの吐出端から内容物を吐出させる。

特開2003−72864号公報JP 2003-72864 A

しかしながら、上記従来の吐出キャップでは、以下の課題が残されていた。すなわち、従来の吐出キャップでは、連通開口に弁体を設けているため、部品点数も多く組立作業に手間がかかり、また、生産性が劣るという問題がある。   However, the following problems remain in the conventional discharge cap. That is, in the conventional discharge cap, since the valve body is provided in the communication opening, the number of parts is large, and it takes time to assemble, and the productivity is inferior.

そこで、本発明は、弁体を設けることなく内容物の逆流及び外気の流入を防止できる吐出キャップを提供することを目的とする。   Then, an object of this invention is to provide the discharge cap which can prevent the backflow of contents and the inflow of external air, without providing a valve body.

本発明は、上記課題を解決するために以下のような手段を採用した。すなわち、本発明の吐出キャップは、内容物を収容する容器本体の口部に装着される有頂筒状の吐出ヘッドと、前記吐出ヘッドの周方向に重ね合わされた状態で前記吐出ヘッドの周壁部から径方向外側に向けて延在する一対のフィルム体と、を備え、前記吐出ヘッドの周壁部には、前記容器本体の内部に連通する連通開口が形成されると共に、一対の前記フィルム体は、前記周壁部において前記連通開口の周縁部に固着され、一対の前記フィルム体同士の間には、互いに離間可能に密着して前記連通開口に連通可能であり、かつ径方向外側の端部が開口された吐出通路が画成され、前記吐出ヘッドには、前記吐出通路内に位置する介装体が配設されていることを特徴とする。   The present invention employs the following means in order to solve the above problems. That is, the discharge cap of the present invention includes a top cylindrical discharge head attached to the mouth of the container main body that contains the contents, and a peripheral wall portion of the discharge head in a state of being overlapped in the circumferential direction of the discharge head. A pair of film bodies extending radially outward from the peripheral wall portion of the discharge head, a communication opening communicating with the interior of the container body is formed, and the pair of film bodies is The peripheral wall portion is fixed to a peripheral edge portion of the communication opening, and can be connected to the communication opening so as to be separable from each other between the pair of film bodies, and a radially outer end portion is provided. An opened discharge passage is defined, and an interposition body located in the discharge passage is disposed in the discharge head.

この発明では、一対のフィルム体によって連通開口と外部と間の連通が遮断されるので、弁体を設けることなく内容物の逆流及び外気の流入を防止できる。
すなわち、内容物の吐出時において例えば容器本体を傾けたりスクイズ変形させたりすることによって容器本体内の内容物を連通開口から流出させると、流出した内容物は、介装体における吐出通路内に位置する部分を起点として、互いに密着している吐出通路を膨出させる。そして、内容物は、吐出通路において互いに密着している一対のフィルム体を離間させながら吐出通路内を径方向外側の端部に向けて流動し、この端部を開口して連通開口と外部とを連通させる。これにより、内容物がこの端部から吐出される。さらに、容器本体を正立姿勢にしたりスクイズ変形を解除したりして吐出端からの内容物の吐出を停止すると、内容物によって離間していた一対のフィルム体が再度密着し、連通開口と外部との連通を再度遮断する。これにより、容器本体の密閉性が再度確保される。このように、離間可能に密着している一対のフィルム体によって容器本体の密閉性が確保されるため、部品点数の削減、組立作業の簡略化及び生産性の向上が図れる。
また、一対のフィルム体が離間可能に密着しているので、一方のフィルム体に皺や局所的な膨らみなどの癖がついてしまっても、他方のフィルム体がこのような癖に追従するように変形してこの癖を吸収でき、一対のフィルム体同士の密着状態が維持されてフィルム体間に隙間などが発生しにくくなる。これによっても、容器本体の密閉性が確保される。
さらに、一対のフィルム体が径方向外側に延在して端部が径方向外側を向いており、吐出通路を流通する内容物からの圧力が一対のフィルム体に均等にかかるので、一方のフィルム体に癖が付きにくくなり、吐出を繰り返しても容器本体の密閉性を確保できる。
その上、内容物により吐出通路における一対のフィルム体が離間する際に介装体の上記端部が起点となるので、内容物によるフィルム体の離間動作が安定する。
In the present invention, since the communication opening and the outside are blocked by the pair of film bodies, the backflow of the contents and the inflow of the outside air can be prevented without providing a valve body.
That is, when the contents in the container body are caused to flow out of the communication opening by, for example, tilting or squeezing the container body at the time of discharging the contents, the discharged contents are positioned in the discharge passage in the interposer. The discharge passages that are in close contact with each other are swelled starting from the portion to be used. The contents flow in the discharge passage toward the radially outer end while separating the pair of film bodies that are in close contact with each other in the discharge passage, and open the end to open the communication opening and the outside. To communicate. Thereby, the contents are discharged from this end. Further, when the discharge of the contents from the discharge end is stopped by bringing the container body into an upright posture or releasing the squeeze deformation, the pair of film bodies separated by the contents are brought into close contact with each other, and the communication opening and the outside Block communication with again. Thereby, the sealing property of a container main body is ensured again. As described above, since the sealability of the container body is ensured by the pair of film bodies that are in close contact with each other, the number of parts can be reduced, the assembling work can be simplified, and the productivity can be improved.
In addition, since the pair of film bodies are in close contact with each other, even if one film body has wrinkles such as wrinkles or local swelling, the other film body follows such wrinkles. The film can be deformed to absorb the wrinkles, and a close contact state between the pair of film bodies is maintained, so that a gap or the like is hardly generated between the film bodies. This also ensures the sealing of the container body.
Furthermore, since the pair of film bodies extends radially outward and the end faces radially outward, and the pressure from the contents flowing through the discharge passage is equally applied to the pair of film bodies, one film The body is less likely to be wrinkled, and the sealing of the container body can be secured even after repeated discharges.
In addition, when the pair of film bodies in the discharge passage are separated from each other by the contents, the above-described end portions of the interposition bodies are used as starting points, so that the separation operation of the film bodies by the contents is stabilized.

また、本発明の吐出キャップは、前記周壁部は、前記連通開口の上下両端から径方向外側に向けて突出する一対の支持突出部を有し、一対の前記支持突出部には、一対の前記フィルム体それぞれの径方向内側の端部が各別に固着され、前記介装体は、一対の前記支持突出部において互いに対向する表面のうち少なくとも一方に連設されると共に、径方向外側の端部が前記支持突出部よりも径方向外側に位置しており、前記支持突出部の径方向外側の端部と前記介装体との間には、空隙部が形成されていることが好ましい。
この発明では、空隙部を形成することにより、上述した吐出通路における一対のフィルム体の離間が吐出通路の軸方向において均等に進行するので、内容物の吐出がより均一になる。
Further, in the discharge cap of the present invention, the peripheral wall portion has a pair of support protrusions that protrude radially outward from upper and lower ends of the communication opening, and a pair of the support protrusions includes a pair of the above-described support protrusions. The radially inner ends of the film bodies are fixed separately, and the interposer is connected to at least one of the opposing surfaces of the pair of supporting protrusions, and the radially outer ends. Is preferably located radially outside of the support protrusion, and a gap is preferably formed between the radially outer end of the support protrusion and the interposer.
In the present invention, by forming the gap, the separation of the pair of film bodies in the discharge passage described above proceeds uniformly in the axial direction of the discharge passage, so that the discharge of the contents becomes more uniform.

この発明にかかる吐出キャップによれば、弁体を別途用いることなく離間可能に密着している一対のフィルム体によって連通開口と外部と間の連通が遮断されて容器本体の密閉性が確保されるので、部品点数の削減、組立作業の簡略化及び生産性の向上が図れる。また、一対のフィルム体同士の密着状態が維持されてフィルム体間に隙間などが発生しにくくなる。そして、吐出通路を流通する内容物からの圧力が一対のフィルム体に均等にかかるので、吐出操作を繰り返しても容器本体の密閉性を確保できる。さらに、内容物によって吐出通路における一対のフィルム体が離間する際に介装体の上記端部を起点とすることで、内容物によるフィルム体の離間動作が安定する。   According to the discharge cap according to the present invention, the communication between the communication opening and the outside is blocked by the pair of film bodies that are in close contact with each other without using a separate valve body, and the hermeticity of the container body is ensured. Therefore, the number of parts can be reduced, the assembly work can be simplified, and the productivity can be improved. Moreover, the contact | adherence state of a pair of film bodies is maintained, and it becomes difficult to generate | occur | produce a clearance gap between film bodies. And since the pressure from the content which distribute | circulates a discharge channel applies to a pair of film body equally, even if discharge operation is repeated, the sealing property of a container main body is securable. Further, when the pair of film bodies in the discharge passage are separated by the contents, the separation operation of the film bodies by the contents is stabilized by using the end portions of the interposition bodies as starting points.

以下、本発明による吐出キャップの一実施形態を、図面に基づいて説明する。なお、以下の説明に用いる各図面では、各部材を認識可能とするために縮尺を適宜変更している。
本実施形態における吐出キャップ1は、図1に示すように、内容物を収容した容器本体2に装着されて吐出容器3を構成する。
ここで、図1に示す軸線Oは、容器本体2の中心軸線を示している。以下、この軸線O方向に沿って吐出キャップ1側を上方(図1における上側)として、その反対側(図1における下側)を下方とする。また、軸線O方向を軸方向、軸線Oに直交する方向を径方向、軸線O回りの方向を周方向とする。
Hereinafter, an embodiment of a discharge cap according to the present invention will be described with reference to the drawings. In each drawing used in the following description, the scale is appropriately changed so that each member can be recognized.
As shown in FIG. 1, the discharge cap 1 in the present embodiment is mounted on a container body 2 that contains contents, and constitutes a discharge container 3.
Here, the axis O shown in FIG. 1 indicates the central axis of the container body 2. Hereinafter, the discharge cap 1 side is defined as the upper side (upper side in FIG. 1) along the axis O direction, and the opposite side (lower side in FIG. 1) is defined as the lower side. The direction of the axis O is the axial direction, the direction orthogonal to the axis O is the radial direction, and the direction around the axis O is the circumferential direction.

まず、吐出キャップ1が装着される容器本体2の構成を簡単に説明する。容器本体2は、図1に示すように、可撓性を有する外側容器11と内側容器12とが離間可能に積層された積層離間(デラミ)容器であり、スクイズ変形可能な胴部を有している。この構成の場合には、内容物の減少と共に内側容器12が収縮するため、内容物の保存性を高めることができ、また、内容物の残量が少なくなっても良好な吐出操作が行える。なお、容器本体2としては、ボトル状の外側容器11の内側に内容物を収容した袋状の内側容器12を収容した容器など、他の構成の容器であってもよい。
外側容器11の上端部には、円筒状をなして軸方向に延在する口部13が立設されており、この口部13の外周面には、雄ネジ部13Aが形成されている。また、口部13には、外側容器11と内側容器12との間に外気を導入する外気導入穴13Bが形成されている。
First, the configuration of the container body 2 to which the discharge cap 1 is attached will be briefly described. As shown in FIG. 1, the container main body 2 is a laminated and separated (delamination) container in which an outer container 11 having flexibility and an inner container 12 are laminated so as to be separable, and has a body that can be squeezed. ing. In the case of this configuration, the inner container 12 contracts as the contents decrease, so that the storability of the contents can be improved, and a good discharge operation can be performed even if the remaining amount of the contents decreases. The container body 2 may be a container having another configuration, such as a container containing a bag-like inner container 12 containing contents inside a bottle-like outer container 11.
A mouth portion 13 that is cylindrical and extends in the axial direction is erected at the upper end portion of the outer container 11, and a male screw portion 13 </ b> A is formed on the outer peripheral surface of the mouth portion 13. In addition, the mouth portion 13 is formed with an outside air introduction hole 13 </ b> B for introducing outside air between the outer container 11 and the inner container 12.

吐出キャップ1は、図1から図3に示すように、容器本体2の口部13に装着される吐出ヘッド21と、吐出ヘッド21に固着された一対のフィルム体22と、吐出ヘッド21に連設された介装体23と、を備えている。
吐出ヘッド21は、有頂円筒状をなしており、周壁部31と頂壁部32と装着筒部33とシール筒部34とを備えている。
周壁部31は、円筒状をなしており、また、周壁部31には、周壁部31の外側と内側容器12の内側とを連通する連通開口31Aが形成されている。また、周壁部31には、連通開口31Aの上下両端から径方向外側に向けて突出する一対の支持突出部35が突設されている。支持突出部35における周方向の幅は、基端において連通開口31Aの周方向の幅よりも大きく、上記軸方向から見たときに径方向外側の端部が鋭い角部を形成するように、径方向外側に向かうにしたがって周方向の幅が漸次小さくなっている。
As shown in FIGS. 1 to 3, the discharge cap 1 is connected to the discharge head 21 attached to the mouth portion 13 of the container body 2, a pair of film bodies 22 fixed to the discharge head 21, and the discharge head 21. And an intervening body 23 provided.
The discharge head 21 has a cylindrical shape with a top, and includes a peripheral wall portion 31, a top wall portion 32, a mounting tube portion 33, and a seal tube portion 34.
The peripheral wall portion 31 has a cylindrical shape, and the peripheral wall portion 31 is formed with a communication opening 31 </ b> A that communicates the outside of the peripheral wall portion 31 and the inside of the inner container 12. The peripheral wall 31 is provided with a pair of support protrusions 35 that protrude radially outward from both upper and lower ends of the communication opening 31A. The circumferential width of the support protrusion 35 is larger than the circumferential width of the communication opening 31A at the proximal end, and the radially outer end forms a sharp corner when viewed from the axial direction. The width in the circumferential direction gradually decreases toward the outer side in the radial direction.

頂壁部32は、平面視円状をなしており、周壁部31の上端に連設されている。
装着筒部33は、円筒状をなしており、周壁部31の下端に連設されて径方向外側に突出するフランジ部36の外周縁から垂下されている。また、装着筒部33の内周面には、口部13の雄ネジ部13Aと螺合する雌ネジ部33Aが形成されている。
シール筒部34は、周壁部31の下端から垂下する円筒状をなしており、吐出ヘッド21を口部13に螺着した際に口部13内に嵌入される。
The top wall portion 32 has a circular shape in plan view, and is connected to the upper end of the peripheral wall portion 31.
The mounting cylinder portion 33 has a cylindrical shape, and is suspended from the outer peripheral edge of the flange portion 36 that is connected to the lower end of the peripheral wall portion 31 and protrudes radially outward. In addition, a female screw portion 33 </ b> A that engages with the male screw portion 13 </ b> A of the mouth portion 13 is formed on the inner peripheral surface of the mounting cylinder portion 33.
The seal cylinder portion 34 has a cylindrical shape that hangs down from the lower end of the peripheral wall portion 31, and is fitted into the mouth portion 13 when the discharge head 21 is screwed to the mouth portion 13.

一対のフィルム体22は、可撓性を有する膜体によって形成されており、吐出ヘッド21の周方向に重ね合わされた状態で周壁部31から径方向外側に向けて延在する帯状をなしている。そして、一対のフィルム体22それぞれは、径方向内側の端部が一対の支持突出部35それぞれに固着(接着、溶着など)されると共に、対向するフィルム体の周縁部も固着されている。また、一対のフィルム体22の間には、互いに離間可能に密着して連通開口31Aに連通可能であり、かつ径方向外側の端部が開口された吐出通路41(前記固着部分より内側の領域)が画成されている。
したがって、一対のフィルム体22は、協働して連通開口31Aの周方向の両端部から連通開口31Aを覆って、連通開口31Aと吐出容器3の外部との連通を遮断している。
The pair of film bodies 22 is formed of a flexible film body and has a belt shape extending radially outward from the peripheral wall portion 31 in a state of being overlapped in the circumferential direction of the ejection head 21. . In each of the pair of film bodies 22, the radially inner ends are fixed (adhered, welded, etc.) to the pair of support protrusions 35, and the peripheral edges of the opposing film bodies are also fixed. The pair of film bodies 22 are in close contact with each other so as to be separable from each other and can communicate with the communication opening 31 </ b> A, and the discharge passage 41 (the region on the inner side of the fixing portion) that is open at the radially outer end. ) Is defined.
Accordingly, the pair of film bodies 22 cooperate to cover the communication opening 31A from both ends in the circumferential direction of the communication opening 31A, thereby blocking communication between the communication opening 31A and the outside of the discharge container 3.

さらに、フィルム体22の径方向外側の端部には、破断部42が形成されており、この破断部42の下端には、下方に向けて突出するツマミ部43が形成されている。また、破断部42における径方向内側の端部の下端には、上方に向けて窪む窪み部42Aが形成されている。そのため、ツマミ部43を指などで摘んで上方に引き上げて破断部42を破断予定線42Bに沿って破断することにより、吐出通路41の径方向外側の端部が露出される。   Furthermore, a rupture portion 42 is formed at an end portion on the radially outer side of the film body 22, and a knob portion 43 that protrudes downward is formed at the lower end of the rupture portion 42. In addition, at the lower end of the radially inner end of the fracture portion 42, a recess 42A that is recessed upward is formed. Therefore, the knob portion 43 is picked with a finger or the like and pulled upward to break the fracture portion 42 along the planned fracture line 42B, thereby exposing the radially outer end of the discharge passage 41.

介装体23は、板状をなしており、上側の支持突出部35の下面に連設されている。また、介装体23の径方向外側の端部は、支持突出部35よりも径方向外側に突出しており、吐出通路41内に位置している。そのため、介装体23の径方向外側の端部は、一対のフィルム体22によって挟み込まれている。
また、介装体23と上側の支持突出部35における径方向外側の端部との間には、空隙部23Aが形成されている。
The intervening body 23 has a plate shape and is connected to the lower surface of the upper support protrusion 35. In addition, the end portion on the radially outer side of the interposition body 23 projects outward in the radial direction from the support projecting portion 35, and is located in the discharge passage 41. Therefore, the radially outer end of the interposition body 23 is sandwiched between the pair of film bodies 22.
Further, a gap 23A is formed between the interposition body 23 and the radially outer end of the upper support protrusion 35.

次に、以上のような構成の吐出キャップ1を用いた内容物の吐出方法について説明する。
まず、ツマミ部43を指などで摘んで上方に引き上げ、破断予定線42Bに沿ってフィルム体22を破断して、吐出通路41の径方向外側の端部を露出させる。そして、容器本体2を傾けたり、容器本体2の胴部をスクイズ変形させて内側容器12の内圧を高めたりすることによって、内側容器12内の内容物を連通開口31Aから流出させる。
Next, a method for discharging contents using the discharge cap 1 having the above configuration will be described.
First, the knob portion 43 is picked up with a finger or the like and pulled upward, the film body 22 is broken along the planned breaking line 42B, and the radially outer end of the discharge passage 41 is exposed. Then, the contents in the inner container 12 are caused to flow out of the communication opening 31 </ b> A by tilting the container body 2 or increasing the internal pressure of the inner container 12 by squeezing the body portion of the container body 2.

このとき、連通開口31Aから流出する内容物は、互いに密着している吐出通路41における一対のフィルム体22間を膨出させる。ここで、一対のフィルム体22が介装体23の上記端部を挟み込んでおり、この端部において一対のフィルム体22同士の密着性が弱められているため、内容物は、この突出部分を起点として互いに密着しているフィルム体22を離間させる。また、介装体23の先端に空隙部23Aが形成されており、介装体23の上記端部が上側の支持突出部35から離間しているため、上記端部を起点として一対のフィルム体22を離間する動作がフィルム体22の上下方向で均等に行われる。   At this time, the content flowing out from the communication opening 31A bulges between the pair of film bodies 22 in the discharge passage 41 in close contact with each other. Here, since a pair of film body 22 has pinched | interposed the said edge part of the interposition body 23, and the adhesiveness of a pair of film body 22 is weakened in this edge part, the content removes this protrusion part. As a starting point, the film bodies 22 that are in close contact with each other are separated. In addition, since a gap 23A is formed at the tip of the interposition body 23 and the end of the interposition body 23 is separated from the upper support protrusion 35, the pair of film bodies starts from the end. The operation of separating 22 is performed uniformly in the vertical direction of the film body 22.

そして、内容物は、図4に示すように、一対のフィルム体22を互いに離間させながら吐出通路41を径方向外側に向けて流動し、吐出通路41の径方向外側の端部を開口させる。これにより、連通開口31Aと吐出容器3の外部とが連通し、内容物は、吐出通路41の径方向外側の端部から外部に吐出される。
ここで、内容物が吐出されるにしたがって内側容器12の容積が減少するが、外側容器11の口部13に形成された外気導入穴13Bを介して外側容器11と内側容器12との間に外気が導入されるため、外側容器11に対して内側容器12が離間して変形する。
Then, as shown in FIG. 4, the contents flow toward the radially outer side of the discharge passage 41 while separating the pair of film bodies 22 from each other, thereby opening the radially outer end of the discharge passage 41. Accordingly, the communication opening 31 </ b> A communicates with the outside of the discharge container 3, and the contents are discharged to the outside from the radially outer end of the discharge passage 41.
Here, the volume of the inner container 12 decreases as the contents are discharged, but between the outer container 11 and the inner container 12 through the outside air introduction hole 13B formed in the mouth portion 13 of the outer container 11. Since the outside air is introduced, the inner container 12 is separated from the outer container 11 and deformed.

また、内容物の吐出を終了させる場合には、容器本体2を正立姿勢に戻したり、容器本体2の胴部のスクイズ変形を解除したりすることによって、連通開口31Aからの内容物の流出を停止させる。そして、一対のフィルム体22は、吐出通路41の径方向外側の端部から径方向内側に向けて順次密着していく。これにより、一対のフィルム体22は、連通開口31Aと外部との連通を再び遮断する。
以上のようにして、内容物を吐出させる。
Further, when the discharge of the contents is terminated, the contents are discharged from the communication opening 31A by returning the container body 2 to an upright posture or canceling the squeeze deformation of the body portion of the container body 2. Stop. Then, the pair of film bodies 22 are in close contact with each other sequentially from the radially outer end of the discharge passage 41 toward the radially inner side. Accordingly, the pair of film bodies 22 again blocks communication between the communication opening 31A and the outside.
The contents are discharged as described above.

内容物を再度吐出させる場合には、上述と同様の操作を繰り返すことによって行う。ここで、吐出通路41が径方向外側に開口しており、フィルム体22が径方向に沿って延在しているため、吐出通路41内を流通する内容物による圧力が一対のフィルム体22それぞれに対して均等にかかる。そのため、内容物を繰り返し吐出させても、一対のフィルム体22同士の密着性が劣化することを防止し、一対のフィルム体22が連通開口31Aと吐出容器3の外部との連通を遮断できなくなることを阻止する。   When the contents are discharged again, the same operation as described above is repeated. Here, since the discharge passage 41 is opened radially outward and the film body 22 extends along the radial direction, the pressure due to the contents flowing through the discharge passage 41 is respectively applied to the pair of film bodies 22. Takes evenly. Therefore, even if the contents are repeatedly discharged, the adhesiveness between the pair of film bodies 22 is prevented from deteriorating, and the pair of film bodies 22 cannot block communication between the communication opening 31A and the outside of the discharge container 3. Stop that.

以上より、本実施形態における吐出キャップ1によれば、一対のフィルム体22によって連通開口31Aと外部との間の連通を遮断するため、弁体を別途設けることなく容器本体2の密閉性を確保できる。そして、一対のフィルム体22が径方向に沿って延在しかつ吐出通路41が径方向外側を向いて開口しており、吐出通路41内を流通する内容物からの圧力が一対のフィルム体22に均等にかかるため、吐出を繰り返しても容器本体2の密閉性を確保できる。   As described above, according to the discharge cap 1 of the present embodiment, since the communication between the communication opening 31 </ b> A and the outside is blocked by the pair of film bodies 22, the hermeticity of the container body 2 is ensured without providing a valve body separately. it can. The pair of film bodies 22 extend along the radial direction, and the discharge passage 41 opens toward the outer side in the radial direction, and the pressure from the contents flowing through the discharge passage 41 is applied to the pair of film bodies 22. Therefore, even if the discharge is repeated, the container body 2 can be sealed.

また、介装体23の上記端部が一対のフィルム体22によって挟み込まれるため、内容物が一対のフィルム体22を離間させる際に介装体23のこの端部が起点となり、内容物によるフィルム体22の離間動作が安定する。ここで、空隙部23Aが形成されているため、介装体23のこの端部を起点とした内容物によるフィルム体22の離間が吐出通路41の軸方向で均等に進行し、内容物の吐出がより均一になる。   Moreover, since the said edge part of the interposition body 23 is pinched | interposed by a pair of film body 22, when the content separates a pair of film body 22, this edge part of the interposition body 23 becomes a starting point, and the film by a content The separating operation of the body 22 is stabilized. Here, since the gap portion 23A is formed, the separation of the film body 22 by the contents starting from this end portion of the interposition body 23 proceeds uniformly in the axial direction of the discharge passage 41, and the discharge of the contents Becomes more uniform.
