Description

本発明はガスの圧力でパウチを収縮させて内容物を吐出する吐出容器に用いる流路部材およびそれを用いた吐出容器に関する。   The present invention relates to a flow path member used in a discharge container that discharges contents by contracting a pouch with gas pressure, and a discharge container using the same.

外部を押圧して内部に収容された内容物を吐出するパウチを有する吐出容器が知られている。特に、パウチを収容する外部容器を備えたものであって、パウチと外部容器との間に噴射剤を充填したエアゾール式の吐出容器が知られている。このようなパウチには、内部の内容物を確実に外部に吐出するべく流路部材が用いられている。
例えば、特許文献１の図１２には、エアゾール容器のプロダクト・パック（パウチ）に用いられる流れ管が開示されている。また、特許文献２には、エアゾール容器の内装袋（パウチ）の内部に装着される残量低減部材が開示されている。 There is known a discharge container having a pouch that presses the outside to discharge the contents contained therein. In particular, there is known an aerosol-type discharge container provided with an external container for containing a pouch and filled with a propellant between the pouch and the external container. In such a pouch, a flow path member is used to reliably discharge the contents inside.
For example, FIG. 12 of Patent Document 1 discloses a flow tube used for a product pack (pouch) of an aerosol container. Further, Patent Document 2 discloses a remaining amount reducing member mounted inside an interior bag (pouch) of an aerosol container.

特開平６−２８６７７８号公報JP-A-6-286778 特許第５２７９９７０号Japanese Patent No. 5279970

しかし、エアゾール式の吐出容器のように、パウチをガスの圧縮力で収縮させる場合、内容物が少なくなるにつれてパウチの面同士（表裏面）が密着し、吐出を途中で止めても元の形状に戻らないため、一度パウチの面同士の密着によって内容物の流路が閉じられると内容物が隔離され、内容物の残量の原因となる。特に、パウチから内容物をバルブに導出する孔が上部に設けられている場合は、パウチの上部から内容物を送る溝や孔と密着していくため、パウチの上部の流路が閉じられることになり、内容物の残量が多くなるおそれがある。特許文献１の流れ管及び特許文献２の残量低減部材は、パウチが密着しても内容物の通路を確保する形状であるが、溝が開口している方向以外から内容物を通路に誘導することができなくなるため、内容物の流路を十分に確保できず、内容物の残量が多くなる。
また特許文献１の図１２ｃのように、断面串型の流れ管を用いる場合、内容物が吐出されてパウチが収縮すると流れ管にもガスの圧縮力が伝わり、吐出の途中で流れ管の隔壁（枝部）が変形し、隔壁（枝部）が通路側に変形し、通路を塞いでしまうおそれがある。
本発明は、内容物が少なくなりパウチが収縮しても、内容物の流路が確保され、内容物の残量を少なくすることができる流路部材およびそれを用いた吐出容器を提供することを目的としている。 However, when the pouch is shrunk by the compressive force of the gas, such as an aerosol-type discharge container, the surfaces of the pouch (front and back surfaces) come into close contact with each other as the content decreases, and the original shape is maintained even if the discharge is stopped halfway. Therefore, once the flow path of the content is closed due to the close contact between the surfaces of the pouch, the content is isolated, causing the remaining amount of the content. In particular, when a hole for leading the contents from the pouch to the valve is provided at the top, the flow path at the top of the pouch must be closed in order to be in close contact with the groove and hole for sending the contents from the top of the pouch. And the remaining amount of contents may increase. The flow tube of Patent Document 1 and the remaining amount reducing member of Patent Document 2 have a shape that secures the passage of the contents even when the pouch is in close contact, but guides the contents from the direction other than the direction in which the groove is open. Therefore, it is impossible to secure a sufficient flow path for the contents, and the remaining amount of contents increases.
When a flow tube having a cross-section skewer is used as shown in FIG. 12c of Patent Document 1, when the contents are discharged and the pouch contracts, the compressive force of the gas is also transmitted to the flow tube, and the partition of the flow tube is in the middle of discharge. There is a possibility that the (branch part) is deformed, the partition wall (branch part) is deformed to the passage side, and the passage is blocked.
The present invention provides a flow path member that can secure a flow path for the contents and reduce the remaining amount of the contents even when the contents are reduced and the pouch contracts, and a discharge container using the same. It is an object.

本発明の吐出容器は、耐圧性を有する外部容器と、その外部容器に収容され、内容物を収容するためのパウチと、その外部容器の開口部に固着されるバルブアッセンブリと、前記パウチとバルブアッセンブリとを連結する本発明の流路部材とを備えていることを特徴としている。
このような吐出容器であって、パウチが異なる内容物を収容するために複数個設けられており、流路部材がそれぞれのパウチとバルブアッセンブリに連結するために複数個設けられていてもよい。 A discharge container according to the present invention includes a pressure-resistant outer container, a pouch accommodated in the outer container for accommodating contents, a valve assembly fixed to the opening of the outer container, and the pouch and valve. The flow path member of the present invention for connecting the assembly is provided.
In such a discharge container, a plurality of pouches may be provided to accommodate different contents, and a plurality of flow path members may be provided to connect to the respective pouches and valve assemblies.

本発明の流路部材は、ガスの圧力でパウチを収縮させて内容物を吐出する吐出容器に用いる流路部材であって、前記吐出容器のバルブに装着される筒状の装着部と、その装着部の下端に同軸上に設けられ、前記パウチの開口部が固定される筒状の固定部と、その固定部の下端からパウチの底部に向かって延び、内容物を固定部内に誘導する誘導部を備えており、前記誘導部が、上下方向に延びる誘導部本体と、その誘導部本体の上端に設けられ、前記誘導部本体の表面と前記固定部の中心孔とを連通する連通部と、前記誘導部本体から突出した突出部とを備えており、前記突出部が、同一線上に、上下方向に離れて形成されている少なくとも２つの主突条を有しているため、内容物の残量が少なくなり、パウチが収縮してもパウチ内における固定部の中心孔に内容物を導く流路が確保され、内容物を最後まで吐出させることができる。詳しくは、誘導部本体から突出した突出部が、同一線上に、上下方向に離れて形成されている少なくとも２つの主突条を備えているため、誘導部本体に凹凸が形成されて誘導部全体の表面積が増大し、パウチが収縮したときにパウチと誘導部との間に隙間が形成されやすくなる。特に、パウチと主突条のすそ部との間に隙間が形成されやすく、主突条と平行な流路が形成される。また、隣接する主突条の間の平面（誘導部本体の表面）上に隙間が形成され、大きな流路が確保できる。さらに、主突条によって形成される流路及び平面状の隙間が同一線上に形成されるため、内容物を効率よく誘導できる。   The flow path member of the present invention is a flow path member used for a discharge container that discharges contents by contracting a pouch with gas pressure, and includes a cylindrical mounting portion that is mounted on a valve of the discharge container, A cylindrical fixing portion that is coaxially provided at the lower end of the mounting portion and to which the opening portion of the pouch is fixed, and a guide that extends from the lower end of the fixing portion toward the bottom portion of the pouch and guides the contents into the fixing portion. A guiding portion main body extending in the vertical direction, and a communication portion provided at an upper end of the guiding portion main body and communicating the surface of the guiding portion main body with the central hole of the fixing portion. A protrusion protruding from the guide body, and the protrusion has at least two main protrusions formed on the same line and separated in the vertical direction. Even if the remaining amount decreases and the pouch shrinks, The flow path is ensured that the center hole of the tough directing the contents can be discharged the contents to the end. Specifically, since the protruding portion protruding from the guiding portion main body has at least two main protrusions formed on the same line and separated in the vertical direction, the guiding portion main body is formed with irregularities so that the entire guiding portion is formed. When the pouch shrinks, a gap is easily formed between the pouch and the guiding portion. In particular, a gap is easily formed between the pouch and the bottom portion of the main ridge, and a flow path parallel to the main ridge is formed. Moreover, a clearance gap is formed on the plane (surface of the guidance | induction part main body) between adjacent main protrusions, and a big flow path is securable. Furthermore, since the flow path and the planar gap formed by the main protrusions are formed on the same line, the contents can be efficiently guided.

本発明の流路部材であって、前記突出部が、同一線上に設けられた少なくとも２つの主突条と、上下方向に離れた主突条の間の位置に、前記主突条と交差しないように設けられた副突条とを有している場合、さらに誘導部本体上の凹凸が三次元的に形成され、流路部材全体の表面積が一層増大し、流路部材とパウチとの間に一層隙間が形成されやすくなる。特に、パウチが密着しやすい隣接する主突条の間の位置に副突条が設けられているため、隣接する主突条の間の平面（誘導部本体の表面）とパウチとの間に一層隙間が形成されやすい。
また、副突条により主突条のすそ部の流路に導く副流路を形成することができるため、誘導部本体の上端にある連通部に内容物を安定して導出できる。なお、この副流路は、それより下方にある主流路に先んじて内容物を運ぶため、副流路を設けることにより、内容物をパウチの上部から効率よく順次吐出させることができ、内容物の残量を極めて少なくすることができる。特に、上下に複数個の副流路が設けられる場合、内容物を上の副流路から順番に主流路に送ることができるため、一層効率良く内容物を誘導でき、残量を一層少なくすることができる。
さらに、副流路を設けた吐出容器に内容物をステムからパウチに充填するとき、内容物は主流路だけではなく、副流路も通ってパウチ内に充填されため、内容物は真ん中だけでなく、水平方向で広い範囲に充填される。そして、後から充填される内容物によって、下方に押し出される。そのため、最初に充填する内容物の色を変えておくと、色を変えた内容物はパウチの下端に配置させることができる。このように下端に色を変えた内容物を配置させた状態で、内容物をパウチの上部から順次吐出させると、その色を変えた内容物は最後に吐出されることになるため、外部容器がアルミニウムなどの不透明な容器であっても残りが少なくなったことが目視で確認できる。
なお、パウチの上部に収容された内容物から順次吐出させることにより、つまり、吐出に伴いパウチ内の下部に内容物が貯留されることにより、吐出容器全体の重心が下がるため、使用途中の吐出容器であっても、安定して置くことができる。
本発明の流路部材であって、主突条のすそ部に、前記主突条と平行に溝部が設けられている場合、主突条と平行な流路が一層確実に確保できる。
なお、前記主突条がパウチの面に対して垂直に突出しており、前記副突条がパウチの面に対して平行に突出している場合、パウチの収縮過程を制御しやすい。
副突条がパウチの面に対して垂直方向に突出した突起を備えている場合、流路部材の表面積がさらに増大する。特に、突起が上下方向に離れた主突条の間の位置にあるため、パウチの面に対する垂直方向への収縮を制御して主突条に沿った上下方向への流路を確保しつつ、副突条間から主突条のすそ部に導く副流路を確保することができる。 In the flow path member of the present invention, the protruding portion does not intersect the main protrusion at a position between at least two main protrusions provided on the same line and the main protrusion separated in the vertical direction. If the auxiliary protrusions are provided in such a manner, the unevenness on the guiding part main body is further three-dimensionally formed, the surface area of the entire flow path member is further increased, and the flow path member and the pouch It becomes easier to form a gap. In particular, since the sub ridge is provided at a position between adjacent main ridges where the pouch is likely to be in close contact, a layer between the plane between the adjacent main ridges (the surface of the guiding portion main body) and the pouch is further layered. A gap is easily formed.
Further, since the auxiliary channel can form the auxiliary channel leading to the channel of the skirt portion of the main item, the contents can be stably led out to the communicating part at the upper end of the guiding body. In addition, since this subchannel conveys the content prior to the main channel below it, by providing the subchannel, the contents can be efficiently and sequentially discharged from the upper part of the pouch. The remaining amount of can be extremely reduced. In particular, when a plurality of sub-channels are provided at the top and bottom, the contents can be sent to the main channel sequentially from the upper sub-channel, so that the contents can be guided more efficiently and the remaining amount is further reduced. be able to.
Furthermore, when filling the pouch with the contents from the stem into the discharge container provided with the sub-flow path, the content is filled not only in the main flow path but also in the pouch through the sub-flow path, so the content is only in the middle. Instead, it fills a wide range in the horizontal direction. And it is extruded below by the contents filled later. Therefore, if the color of the content to be filled first is changed, the changed content can be arranged at the lower end of the pouch. When the contents are changed from the upper part of the pouch in such a state that the contents changed in color are arranged at the lower end in this way, the contents changed in color will be discharged last, so that the outer container Even if it is an opaque container such as aluminum, it can be visually confirmed that the remaining amount is small.
In addition, by discharging sequentially from the contents stored in the upper part of the pouch, that is, by storing the contents in the lower part of the pouch with the discharge, the center of gravity of the entire discharge container is lowered, so that the discharge during use Even a container can be placed stably.
In the flow channel member of the present invention, when the groove portion is provided in the skirt portion of the main ridge in parallel with the main ridge, the flow channel parallel to the main ridge can be more reliably ensured.
In addition, when the said main protrusion protrudes perpendicularly | vertically with respect to the surface of a pouch and the said auxiliary protrusion protrudes in parallel with respect to the surface of a pouch, it is easy to control the contraction process of a pouch.
When the auxiliary protrusion includes a protrusion protruding in a direction perpendicular to the surface of the pouch, the surface area of the flow path member further increases. In particular, since the protrusion is located between the main ridges separated in the vertical direction, while controlling the contraction in the vertical direction with respect to the surface of the pouch and securing the flow path in the vertical direction along the main ridge, It is possible to secure a secondary flow path that leads from the secondary protrusions to the bottom of the main protrusion.

本発明の流路部材であって、主突条が同一線上に設けられている少なくとも２つの第１主突条と、第１主突条と水平方向に平行して離れており、同一線上に設けられた少なくとも２つの第２主突条とを有している場合、パウチの両面との間で固定部内に導く流路を確保することができ、内容物の残量を極めて少なくすることができる。また、内容物の吐出に伴いパウチが収縮しても、1対の主突条により主突条の突出方向への誘導部の曲がり（
変形）が防止され、最後まで安定して吐出することができる。
副突条が設けられた本発明の流路部材であって、副突条がパウチの面に対して平行に突出している第１副突条と、その第１副突条に対して１８０度の角度を持って平行に突出している第２副突条とを有している場合、主突条のすそ部の流路へ導く副流路を両側に複数形成することができる。さらに、パウチの面に対して平行に突出している1対の副突条に
より、平行方向への誘導部の曲がり（変形）が防止され、最後まで安定して吐出することができる。 In the flow path member of the present invention, at least two first main protrusions on which the main protrusions are provided on the same line are separated from the first main protrusions in parallel to the horizontal direction, and are on the same line. In the case of having at least two second main protrusions provided, it is possible to secure a flow path leading into the fixed portion between both sides of the pouch, and extremely reduce the remaining amount of the contents. it can. In addition, even if the pouch contracts as the contents are discharged, the guide portion bends in the protruding direction of the main ridge by a pair of main ridges (
Deformation) is prevented, and stable discharge can be achieved until the end.
The flow path member of the present invention provided with the auxiliary protrusion, wherein the auxiliary protrusion protrudes in parallel to the surface of the pouch, and 180 degrees with respect to the first auxiliary protrusion. When there is a second sub-projection projecting in parallel with an angle of, a plurality of sub-channels leading to the channel of the skirt portion of the main ridge can be formed on both sides. Further, the pair of sub-projections projecting in parallel to the surface of the pouch prevents the guide portion from being bent (deformed) in the parallel direction, and can be stably discharged to the end.

本発明の吐出容器は、耐圧性を有する外部容器と、その外部容器に収容され、内容物を収容するためのパウチと、その外部容器の開口部に固着されるバルブアッセンブリと、前記パウチとバルブアッセンブリとを連結する本発明の流路部材とを備えているため、使用後におけるパウチに収容される内容物の残量を小さくすることができる。
本発明の吐出容器であって、前記パウチが、異なる内容物を収容するために複数個設けられており、前記流路部材が、それぞれのパウチとバルブアッセンブリに連結するために複数個設けられている場合、複数の内容物を残量少なく吐出することができる。特に、２液式染毛剤のように内容物同士を反応させて効果が発揮される内容物を用いても、最後までその効果を得ることができる。 A discharge container according to the present invention includes a pressure-resistant outer container, a pouch accommodated in the outer container for accommodating contents, a valve assembly fixed to the opening of the outer container, and the pouch and valve. Since the flow path member of the present invention that connects the assembly is provided, the remaining amount of the contents stored in the pouch after use can be reduced.
In the discharge container of the present invention, a plurality of the pouches are provided to accommodate different contents, and a plurality of the flow path members are provided to be connected to the respective pouches and valve assemblies. In the case of being present, a plurality of contents can be discharged with a small remaining amount. In particular, even when a content that exhibits an effect by reacting the contents with each other like a two-component hair dye, the effect can be obtained until the end.

個の第１副突条３２ａと、誘導部本体２６の左側面に形成されており、同一線上に設けられた複数個の第２副突条３２ｂとからなる。この実施形態では、主突条３１の間だけでなく、主突条３１と溶着部２２との間、主突条３１と底部２９との間にもそれぞれ第１副突条３２ａ及び第２副突条３２ｂを設けている。なお、第１副突条３２ａと第２副突条３２ｂも同じ高さ位置で対になるように設けている。なお、副突条３２の上下端の位置は、主突条３１の上下端の位置と重なっている。
副突条３２は、軸線方向の断面形状が半月状となっている（図２ａ参照）。つまり、それぞれの副突状３２の中央において、誘導部本体２６からの突出量が最大となり、上端及び下端に向かって緩やかにその突出量が小さくなっている。
また、第１副突条３２ａおよび第２副突条３２ｂには、パウチの面に対して垂直に（主突条３１と同じ方向に）突出した突起３６が形成されている。この突起３６は、第１副突条３２ａおよび第２副突条３２ｂの表裏面（誘導部本体２６の表裏面）に設けられている（図２ｃ参照）。突起３６は、外端から内側に向かって突出量が大きくなるように傾斜あるいは湾曲しており、また軸線方向の断面形状が半月状となっている。なお、第１副突起３２ａおよびその両側に設けた２つの突起３６で形成される側面を半ラグビーボール状とし、また第２副突起３２ｂおよびその両側に設けた２つの突起３６で形成される側面を半ラグビーボール状とし、略ラグビーボール状にしてもよい。

The groove 34 of the main protrusion 31 is opened between the upper and lower sub-projections 32, and the flat portion 33 communicates with the upper and lower sub-projections 32 through the groove 34. In addition, although the main protrusion 31 and the sub protrusion 32 are provided so that a protrusion part may shift | deviate to an up-down direction, it is provided so that a part of upper and lower ends may overlap. Thereby, the flow path formed by the main protrusion 31 and the sub protrusion 32 is easy to communicate with each other.

次に、この吐出製品の吐出工程、特に、流路部材による流路形成工程を詳述する。
吐出容器１０のステム１３ｂを下方に押し下げることにより、バルブアッセンブリ１３のバルブ機構が開放され、大気とパウチ１２内が連通する。これにより、パウチ１２は、外部容器１１とパウチ１２との間に充填された噴射剤によってパウチ１２が圧縮せしめられ、内容物は流路部材の誘導部２３により連通部２７の中心孔に誘導されてパウチ１２から押し出され、ハウジング１３ａ、ステム１３ｂを通って外部に吐出される。
内容物が押し出されることによってパウチ１２は収縮し、内容物が少なくなると、例えば図３に示すようにパウチ１２の面同士が密着（図３の斜線部がパウチ１２と誘導部２３の当接部位、太線がパウチ１２）するが、次に示すように流路部材１５によって流路が確保される。 Next, the discharge process of this discharge product, particularly the flow path forming process by the flow path member will be described in detail.
By pushing down the stem 13b of the discharge container 10, the valve mechanism of the valve assembly 13 is opened, and the atmosphere and the inside of the pouch 12 are communicated. As a result, the pouch 12 is compressed by the propellant filled between the outer container 11 and the pouch 12, and the contents are guided to the central hole of the communication portion 27 by the guide portion 23 of the flow path member. Then, it is pushed out from the pouch 12 and discharged to the outside through the housing 13a and the stem 13b.
When the contents are pushed out, the pouch 12 contracts, and when the contents are reduced, for example, as shown in FIG. 3, the surfaces of the pouch 12 are in close contact with each other (the hatched portion in FIG. 3 is the contact portion between the pouch 12 and the guide portion 23). The thick line pouches 12), but the flow path is secured by the flow path member 15 as shown below.

すなわち、内容物の吐出に伴い、パウチ１２は連通部２７に近い上部から面同士が接近するように圧縮され、パウチ１２の面が突出部２８と当接する。そして、さらに内容物を吐出すると、パウチ１２は主突条３１と副突条の突起３６を押圧するように垂直方向に変形し、かつ、パウチ１２の側縁近辺（誘導部２３から離れた端部）の面同士が密着して、密着した状態でパウチ１２の中心軸方向に近づくように水平方向に変形する。
このときパウチ１２の垂直方向の変形については、パウチ１２の面に対して垂直方向に突出している主突条３１と突起３６が収縮しようとするパウチ１２の面に対してリブの作用を発揮して、誘導部２３とパウチ１２との間に隙間を形成する。つまり、上下の主突条３１および左右の突起３６で囲まれる平面部３３とパウチ１２との間、ないし、主突条３１のすそ部（溝部３４）とパウチ１２との間に隙間を形成し、誘導部本体２６上に連通部２７へ連通する上下方向の流路Ｐ１が形成される。なお、流路Ｐ１は、同一線上にあるため、内容物を直進させることができ、効率良い流路となる。また、さらにパウチ１２が収縮され、パウチ１２が引き伸ばされて、一部がすそ部と密着したとしても、溝部３４により流路Ｐ１は確保される。 That is, as the contents are discharged, the pouch 12 is compressed so that the surfaces approach each other from the upper part close to the communication portion 27, and the surface of the pouch 12 comes into contact with the protruding portion 28. When the contents are further discharged, the pouch 12 is deformed in the vertical direction so as to press the projections 36 of the main ridge 31 and the sub ridge, and near the side edge of the pouch 12 (the end away from the guide portion 23). Part) are in close contact with each other and deformed in the horizontal direction so as to approach the central axis direction of the pouch 12 in close contact.
At this time, with respect to the vertical deformation of the pouch 12, the ribs act on the surface of the pouch 12 to which the main protrusions 31 and the protrusions 36 project in the direction perpendicular to the surface of the pouch 12 are to contract. Thus, a gap is formed between the guiding portion 23 and the pouch 12. That is, a gap is formed between the flat portion 33 and the pouch 12 surrounded by the upper and lower main protrusions 31 and the left and right protrusions 36, or between the bottom portion (groove portion 34) of the main protrusion 31 and the pouch 12. A vertical flow path P <b> 1 communicating with the communication portion 27 is formed on the guiding portion main body 26. In addition, since the flow path P1 is on the same line, the content can be made to go straight and it becomes an efficient flow path. Further, even if the pouch 12 is further contracted and the pouch 12 is stretched and a part thereof is in close contact with the skirt portion, the flow path P1 is secured by the groove portion 34.

一方、パウチ１２の水平方向の変形については、パウチの面と平行（水平方向）に突出する副突条３２およびパウチの面に対して垂直方向に突出する突起３６により、隣接する副突条３２の間でのパウチの表裏面の密着が阻止される。そして、表裏面が密着したパウチ１２の側縁近辺（誘導部２３から離れた端部）の隣接する副突条の間（中心軸方向）への変形を防止する。そのため、隣接する副突条３２の間に隙間が形成される。この隣接する副突条３２の間にできる隙間が、主突条のすそ部（溝部３４）に連通する副流路Ｐ２となる。この実施の形態では、副流路Ｐ２が上下および左右に複数個確保されているため、内容物はパウチの上部から（上側の副流路Ｐ２から）順次導出される。そのため、たとえ変形（吐出操作）の途中でパウチ１２が誘導部２３の下部で強く密着しても、途中で流路が閉鎖されることがなく、最後まで内容物を吐出することができる。   On the other hand, with respect to the horizontal deformation of the pouch 12, the adjacent auxiliary protrusion 32 is formed by the auxiliary protrusion 32 protruding parallel to the surface of the pouch (horizontal direction) and the protrusion 36 protruding perpendicularly to the surface of the pouch. Between the front and back surfaces of the pouch is prevented. And the deformation | transformation between the adjacent sub protrusions (center-axis direction) of the side edge vicinity (end part away from the guidance | induction part 23) of the pouch 12 to which the front and back were closely_contact | adhered is prevented. Therefore, a gap is formed between the adjacent auxiliary protrusions 32. A gap formed between the adjacent auxiliary protrusions 32 becomes an auxiliary flow path P2 communicating with the skirt portion (groove portion 34) of the main protrusion. In this embodiment, since a plurality of sub flow paths P2 are secured vertically and horizontally, the contents are sequentially led out from the top of the pouch (from the upper sub flow path P2). Therefore, even if the pouch 12 is in close contact with the lower portion of the guide portion 23 during deformation (discharge operation), the flow path is not closed in the middle, and the contents can be discharged to the end.

なお、主突条３１は、軸線方向の断面形状が半月状であるため、平面部との間に隙間を確保しやすい。また図２ｃに示すように、水平方向の断面形状が頂点が湾曲した山型となっているため、パウチがガスの圧力により主突条に強く密着しても、パウチ１２が裂けたりすることがない。
また、突起３６も、外端から内側に向かって突出量が大きくなるように傾斜あるいは湾曲しており、また軸線方向の断面形状が半月状となっているため、パウチがガスの圧力により突起３６に強く密着しても、パウチ１２が裂けたりすることがない。 In addition, since the main protrusion 31 has a half-moon shape in the axial direction, it is easy to secure a gap between the main protrusion 31 and the flat surface portion. Further, as shown in FIG. 2c, since the horizontal cross-sectional shape is a mountain shape with a curved apex, the pouch 12 may be torn even if the pouch is tightly adhered to the main protrusion due to the gas pressure. Absent.
Further, the protrusion 36 is also inclined or curved so that the amount of protrusion increases from the outer end toward the inside, and the cross-sectional shape in the axial direction is a half-moon shape. The pouch 12 does not tear even if it adheres strongly to the surface.

図４ａ〜ｃの流路部材は、図１の流路部材１５の代わりに用いることができるものである。
図４ａの流路部材４０ａは、図１の流路部材１５の平面部３３が誘導部本体２６を貫通する貫通孔４１となっている。このように貫通孔４１を設けることにより、材料の削減ができる。他の構成は、図１の流路部材１５と実質的に同じであり、装着部２１、溶着部（固定部）２２、誘導部２３を備えている。
図４ｂの流路部材４０ｂは、副突条４２ａ、４２ｂが等脚台形となるように流路部材本体から突出しており、また、図１の流路部材１５の副突条３２ａ、３２ｂより上下方向に長く形成され、かつ、上下に隣接する副突条４２ａ、４２ｂの間隔が小さくなっている。このように副突条４２ａ、ｂを設けることにより、副突条４２ａ間および副突条４２ｂ間の距離が短くなり、副流路Ｐ２が一層確保しやすくなる。他の構成は、図１の流路部材１５と実質的に同じであり、装着部２１、溶着部（固定部）２２、誘導部２３を備えている。
図４ｃの流路部材４０ｃは、主突条４３ａ、ｂが図１の流路部材１５の主突条３１ａ、３１ｂより誘導部本体２６からの突出量を大きくしたものである。これにより、誘導部本体２６の凹凸が一層大きくなり、流路Ｐ１が一層確保しやすくなる。 4a to 4c can be used in place of the flow path member 15 of FIG.
The flow path member 40a of FIG. 4a is a through hole 41 through which the flat portion 33 of the flow path member 15 of FIG. By providing the through hole 41 in this way, the material can be reduced. Other configurations are substantially the same as those of the flow path member 15 of FIG. 1, and include a mounting portion 21, a welded portion (fixed portion) 22, and a guide portion 23.
The channel member 40b in FIG. 4b protrudes from the channel member main body so that the sub-projections 42a and 42b are isosceles trapezoids, and is above and below the sub-projections 32a and 32b of the channel member 15 in FIG. The interval between the sub-ridges 42a and 42b that are long in the direction and are vertically adjacent to each other is small. By providing the auxiliary protrusions 42a and 42b in this manner, the distance between the auxiliary protrusions 42a and the auxiliary protrusions 42b is shortened, and the auxiliary flow path P2 can be more easily secured. Other configurations are substantially the same as those of the flow path member 15 of FIG. 1, and include a mounting portion 21, a welded portion (fixed portion) 22, and a guide portion 23.
In the flow path member 40c of FIG. 4c, the main protrusions 43a and 43b are larger in the amount of protrusion from the guide portion body 26 than the main protrusions 31a and 31b of the flow path member 15 of FIG.
