Description

噴出ポンプ及び該噴出ポンプを有するポンプ容器Ejection pump and pump container having the ejection pump
　本発明は、逆止弁を備え、ピストン動作により流体を噴出する噴出ポンプ及び該噴出ポンプを有するポンプ容器に関する。 The present invention relates to an ejection pump that includes a check valve and ejects fluid by piston operation, and a pump container having the ejection pump.
　各種ポンプ容器の口部に装着され、ピストン動作により内容物である流体、主に液体を噴出させる噴出ポンプは、種々のものが開発されている（例えば特許文献１参照）。一般的なポンプ構造は、流体の吐出経路上に逆止弁を有しており、ピストン動作により噴出経路の容積を変化させるとともに、逆止弁により流体の動きを規制することで、噴出経路内の圧力を制御し内容物を噴出させる。 Various types of ejection pumps have been developed that are attached to the mouths of various pump containers and eject fluids, mainly liquids, by piston operation (see, for example, Patent Document 1). The general pump structure has a check valve on the fluid discharge path, and changes the volume of the jet path by the piston operation and restricts the movement of the fluid by the check valve. The pressure is controlled and the contents are ejected.
　また噴出ポンプには、内容物を霧状にして噴出させるものや、内容物を泡状にして噴出させるものがある（例えば特許文献２、３参照）。 Also, there are jet pumps that jet the contents in a mist and jet pumps that make the contents foam (see, for example, Patent Documents 2 and 3).

　特許文献１から３に代表されるような噴出ポンプでは、逆止弁として主に鋼球が用いられている。鋼球を用いる逆止弁は、鋼球が上下動する空間が必要となり、コンパクト化に限界がある。また鋼球とともにバネを用いる場合には、部品も小さく、組込みに手間がかかる。 In an ejection pump represented by Patent Documents 1 to 3, a steel ball is mainly used as a check valve. A check valve using a steel ball requires a space in which the steel ball moves up and down, and there is a limit to downsizing. Moreover, when using a spring with a steel ball, parts are also small and it takes time to assemble.
　その他にも種々の逆止弁が用いられているが、基本的には噴出ポンプのピストン運動に連動して噴出経路内を上下動するものが多く、シール部材が上下動する空間を確保する必要がありコンパクト化に限界がある。またシール部材の可動範囲が広い程、不意の動作や引っ掛かり等が発生し易く、逆止弁のシール性が損なわれることがある。 Various other check valves are also used, but basically there are many that move up and down in the ejection path in conjunction with the piston movement of the ejection pump, and it is necessary to secure a space for the seal member to move up and down There is a limit to downsizing. In addition, the wider the movable range of the seal member, the more easily unexpected operations and catches occur, and the sealing performance of the check valve may be impaired.

A material whose surface is coated with metal by vapor deposition, coating, plating, metal foil, or the like may be used, and it can be appropriately selected and used depending on the application, contents, and the like. The specific material may be selected with reference to the inner container 12 shown above.
　噴出口６１には、液体を霧状に噴霧させるスプレーノズル７３が装着されている。スプレーノズル７３は、特定のものに限定されるものではなく、噴霧させる内容物１０や噴霧条件等によって公知のスプレーノズルを適宜選定して用いることができる。またスプレーノズル７３は、必ずしも装着する必要はない。 The spray nozzle 61 is equipped with a spray nozzle 73 that sprays liquid in a mist form.

Is used.
　吸込ユニット３１に取付けられる第一逆止弁ユニット８１と噴出ユニット５１に取付けられる第二逆止弁ユニット８２とは、大きさが異なるが構成が同一であるため同一の符号を付し、以下、逆止弁ユニットとして同時に説明する。 The first check valve unit 81 attached to the suction unit 31 and the second check valve unit 82 attached to the ejection unit 51 are different in size but have the same configuration, so the same reference numerals are given. It demonstrates simultaneously as a non-return valve unit.
　逆止弁ユニット８１、８２は、逆止弁を取付容易に且つコンパクトにユニット化したものであり、弁孔８４を有する基台８３と、基台８３に接着され吐出口８８を形成する薄膜のフィルム８７とで構成され、フィルム８７により弁孔８４を開閉させ、弁孔８４から吐出口８８への一方向のみ流体を流通させる。 The check valve units 81 and 82 are unitized easily and compactly so that the check valve can be easily mounted. The base 83 has a valve hole 84 and a thin film that is bonded to the base 83 and forms a discharge port 88. The valve 87 is opened and closed by the film 87, and the fluid is circulated only in one direction from the valve hole 84 to the discharge port 88.
　基台８３は、弁孔８４を有する円板であり、合成樹脂材からなる。但し、材質は特定の材質に限定されるものではなく、合成樹脂の他、例えば金属、ガラス、炭素、焼結材、木材等が例示され、これらの複合材や、蒸着、塗布、メッキ、金属箔等により表面を金属で被覆した材料等でもよく、用途、内容物等に応じて適宜選択して使用することができる。具体的な材料は、先に示した内側容器１２を参考に選定すればよい。 The base 83 is a disc having a valve hole 84 and is made of a synthetic resin material. However, the material is not limited to a specific material, and other than synthetic resin, for example, metal, glass, carbon, sintered material, wood, etc. are exemplified, and these composite materials, vapor deposition, coating, plating, metal A material whose surface is coated with a metal with a foil or the like may be used, and the material can be appropriately selected and used depending on the application, contents and the like. The specific material may be selected with reference to the inner container 12 shown above.
　基台８３は、変形し難い剛性を有することを基本形とするが、フィルム８７よりも剛性が大きく、逆止弁ユニット８１、８２の開弁時にはフィルム８７が基台８３から浮き上がるように、かつ逆止弁ユニット８１、８２の閉弁時にはフィルム８７が基台８３に密着する剛性を有していれば剛性の大きさは特に問われない。基台８３の厚さも特定の厚さに限定されるものではない。また基台８３の外径は、被取付部の大きさに合わせて適宜決めることができる。 The base 83 has a basic shape that is hard to be deformed. However, the base 83 is larger in rigidity than the film 87. When the check valve units 81 and 82 are opened, the film 87 is lifted from the base 83 and the reverse. When the valve stop units 81 and 82 are closed, the rigidity of the film 87 is not particularly limited as long as the film 87 has rigidity to be in close contact with the base 83. The thickness of the base 83 is not limited to a specific thickness. Further, the outer diameter of the base 83 can be appropriately determined according to the size of the attached portion.
　基台８３の上面には、弁孔８４を内包し、フィルム８７が重ねられる弁部８５が確保されている。また基台８３上の弁部８５を除いた任意の領域が逆止弁ユニット８１、８２の取付時に被取付部に当接する取付部８６となる。取付部８６の範囲は、被取付部の形状等によって異なり、弁部８５を除いた範囲であれば特定の範囲に限定されるものではない。本実施形態においては、基台８３の上面の周縁部が取付部８６となる。 On the upper surface of the base 83, a valve portion 85 that includes a valve hole 84 and on which a film 87 is stacked is secured. Further, an arbitrary region excluding the valve portion 85 on the base 83 becomes an attachment portion 86 that comes into contact with the attachment portion when the check valve units 81 and 82 are attached. The range of the attaching portion 86 varies depending on the shape of the attached portion, and is not limited to a specific range as long as the valve portion 85 is excluded. In the present embodiment, the peripheral portion of the upper surface of the base 83 serves as the attachment portion 86.
　基台８３の取付部８６の平面度、面粗度、形状等は、当接箇所の気密状態を確保可能に被取付部に応じて適宜決められる。なお逆止弁ユニット８１、８２をパッキン（図示省略）等のシール手段を介して取付けてもよく、このときには取付部８６の平面度、面粗度、形状等の条件を緩和することができる。 The flatness, surface roughness, shape, and the like of the mounting portion 86 of the base 83 are appropriately determined according to the mounted portion so as to ensure an airtight state at the contact portion. The check valve units 81 and 82 may be attached via sealing means such as packing (not shown). At this time, conditions such as flatness, surface roughness, and shape of the attachment portion 86 can be relaxed.
　弁孔８４の数は、限定されず１個、２個以上であってもよい。また弁孔８４の大きさも、特定の大きさのものに限定されるものではない。また弁孔８４は、円孔に限定されるものではなく、例えばスリット孔等でもよい。内容物の粘度等に応じて弁孔８４の数、大きさ、形状を適宜選択すればよいが、直径の小さい円孔を複数個設ける方が、フィルム７１に皺ができ難い。 The number of valve holes 84 is not limited and may be one, two or more. Further, the size of the valve hole 84 is not limited to a specific size. The valve hole 84 is not limited to a circular hole, and may be a slit hole, for example. The number, size, and shape of the valve holes 84 may be appropriately selected in accordance with the viscosity of the contents, but it is difficult for the film 71 to be wrinkled by providing a plurality of circular holes having a small diameter.
　フィルム８７は、薄膜状の円形フィルムであり、可撓性、柔軟性、伸縮性を有する薄膜フィルムが含まれる。フィルム８７の厚さは、特に限定されるものではなく用途、内容物、材質、接着方法等に応じて適宜選択して使用することができる。フィルム８７の厚さの一例を示せば、内容物が醤油（一般的な醤油）のような比較的粘度の低い液体の場合、ポリエチレンフィルムで大凡１０～数百μｍ程度である。但し、この数値に限定されるものではない。 The film 87 is a thin film-like circular film, and includes a thin film having flexibility, flexibility and stretchability. The thickness of the film 87 is not particularly limited, and can be appropriately selected and used according to the application, contents, material, adhesion method, and the like. As an example of the thickness of the film 87, when the content is a liquid having a relatively low viscosity such as soy sauce (general soy sauce), the thickness is about 10 to several hundred μm for a polyethylene film. However, it is not limited to this value.
　フィルム８７としては、ポリエチレンなどの合成樹脂製フィルムや、合成樹脂製のストレッチフィルム、この他、可撓性及び／又は柔軟性を有する薄膜の金属製フィルム、炭素製フィルム、ガラス製フィルム等が例示されるが、特定の材質に限定されるものではなく、用途、内容物、基台８３への接着方法等に応じて適宜選択し使用することができる。例えば、フィルム８７を通じて内側容器１２内に酸素が侵入しないようにするには、内側容器１２等と同様に、酸素遮断性、空気遮断性に優れるプラスチック、複合材、積層材その他材料を使用すればよい。また酸素遮断性と水蒸気遮断性とを同時に要求される場合には、空気の出入りを防ぐ合成樹脂材と水分の蒸発による乾燥を防ぐ合成樹脂材との多層フィルム、その他前記酸素遮断性と水蒸気遮断性とに優れるプラスチック、複合材、積層材等を好適に用いることができる。但し、フィルム８７は、薄膜状であるため、内側容器１２等に比較して気体を透過し易いので、この点を考慮して材質を選定する必要がある。 Examples of the film 87 include a synthetic resin film such as polyethylene, a synthetic resin stretch film, a thin metal film having flexibility and / or flexibility, a carbon film, a glass film, and the like. However, it is not limited to a specific material, and can be appropriately selected and used according to the application, contents, adhesion method to the base 83, and the like. For example, in order to prevent oxygen from entering the inner container 12 through the film 87, as in the inner container 12, etc., plastics, composite materials, laminated materials and other materials having excellent oxygen barrier properties and air barrier properties may be used. Good. When oxygen barrier properties and water vapor barrier properties are required at the same time, a multilayer film of a synthetic resin material that prevents air from entering and exiting and a synthetic resin material that prevents drying due to evaporation of moisture, and other oxygen barrier properties and water vapor barriers. Plastics, composite materials, laminated materials, etc. that are excellent in properties can be suitably used. However, since the film 87 is in a thin film shape, it is easier for gas to permeate than the inner container 12 or the like, and therefore it is necessary to select a material in consideration of this point.
　フィルム８７は、基台８３の弁部８５に包含され、かつ弁孔８４を包含可能な大きさであり、吐出口８８となる外周の一部と、弁孔８４から吐出口８８への吐出経路８９とを除いて基台８３の弁部８５内に弁孔８４を包含するように接着される。 The film 87 is included in the valve portion 85 of the base 83 and has a size capable of including the valve hole 84, and a part of the outer periphery serving as the discharge port 88 and the discharge path from the valve hole 84 to the discharge port 88. The valve hole 84 is bonded to the valve portion 85 of the base 83 except for 89.
　なおフィルム８７の形状は、特定の形状に限定されるものではなく、例えば、弓形や矩形等でもよく、基台８３の弁部８５に包含され（基台８３の取付部８６と重複せず）、かつ弁孔８４を包含可能であればよい。 The shape of the film 87 is not limited to a specific shape, and may be, for example, an arc shape or a rectangle, and is included in the valve portion 85 of the base 83 (not overlapping with the mounting portion 86 of the base 83). And the valve hole 84 may be included.
　また吐出口８８の形成方法は、特定の方法に限定されるものではなく、例えば、後述する予め吐出孔が穿設されたフィルムを用いてもよい。 Further, the method of forming the discharge port 88 is not limited to a specific method, and for example, a film in which discharge holes are formed in advance, which will be described later, may be used.
　吐出経路８９は、弁孔８４から吐出口８８へ直線状となるようにフィルム８７を弁部８５に接着して形成されているが、これに限定されるものではなく、例えば、分岐や集合等の経路を形成してもよく、弁孔８４から吐出口８８へ流体を流通可能であればよい。吐出経路８９は、例えば、吐出口８８を除いてフィルム８７の周縁部を弁部８５に接着し、平面視において円形に形成されていてもよい。 The discharge path 89 is formed by adhering the film 87 to the valve portion 85 so as to be linear from the valve hole 84 to the discharge port 88. However, the present invention is not limited thereto. The flow path may be formed as long as the fluid can flow from the valve hole 84 to the discharge port 88. For example, the discharge path 89 may be formed in a circular shape in a plan view by adhering the peripheral portion of the film 87 to the valve portion 85 except for the discharge port 88.
　フィルム８７は、基本的に逆止弁ユニット８１、８２の使用時に基台８３側の圧力がフィルム８７側の圧力よりも低いときには基台８３に密着して逆止弁を閉弁させ、基台８３側の圧力がフィルム８７側の圧力よりも高いときには基台８３から浮き上がり、逆止弁を開弁させる。またフィルム８７は、基台８３との間に液体が介在すると毛管吸引力が働くように接着される。 The film 87 is basically in close contact with the base 83 and closes the check valve when the pressure on the base 83 side is lower than the pressure on the film 87 side when the check valve units 81 and 82 are used. When the pressure on the 83 side is higher than the pressure on the film 87 side, the pressure rises from the base 83 and the check valve is opened. The film 87 is bonded so that a capillary suction force acts when a liquid is interposed between the film 87 and the base 83.
　吐出口８８は、基台８３の弁孔８４に対して基台８３の中心を挟んで反対側に配置される。弁孔８４から吐出口８８までの距離が短いと、フィルム８７が基台８３に密着して逆止弁が閉弁するよりも先に流体が逆流する恐れがあるが、上記のように吐出口８８を配置すると、弁孔８４から吐出口８８までの距離を長くとることができるため好ましい。但し、吐出口８８と弁孔８４との位置関係は、これに限定されるものではなく、逆止弁ユニット８１、８２の大きさ、内容物、用途等に応じて適宜決定することができる。なお、吐出口８８と弁孔８４とは、一部分でも重複してはいけないことは当然である。 The discharge port 88 is arranged on the opposite side of the center of the base 83 with respect to the valve hole 84 of the base 83. If the distance from the valve hole 84 to the discharge port 88 is short, the fluid may flow backward before the film 87 is brought into close contact with the base 83 and the check valve is closed. The arrangement of 88 is preferable because the distance from the valve hole 84 to the discharge port 88 can be increased. However, the positional relationship between the discharge port 88 and the valve hole 84 is not limited to this, and can be appropriately determined according to the size, contents, usage, and the like of the check valve units 81 and 82. Of course, the discharge port 88 and the valve hole 84 should not overlap even partly.
　吸込ユニット３１に取付けられる第一逆止弁ユニット８１は、上面周縁部の取付部８６を介して段差部４５に接着され、噴出ユニット５１に取付けられる第二逆止弁ユニット８２は、上面周縁部の取付部８６を介して噴出ユニット５１の下端面に接着される。 The first check valve unit 81 attached to the suction unit 31 is bonded to the stepped portion 45 via the attachment portion 86 at the upper peripheral portion, and the second check valve unit 82 attached to the ejection unit 51 is provided at the upper peripheral portion. It adheres to the lower end surface of the ejection unit 51 through the attachment part 86.
　次にポンプ容器１を酸化防止用の醤油差しとして使用する場合を例として、使用方法を例示する。容器本体１１の口部１４から醤油を収容した後に噴出ポンプ２１を口部１４に取付ける。噴出ポンプ２１のキャップ部４３を容器本体１１の口部１４にしっかりと締め付け螺合させると、キャップ部４３の天井面４８のテーパ部分と容器本体１１の口部１４の先端とが当接して密着し当接箇所からの流体の出入りが防止される。 Next, the usage method will be exemplified by using the pump container 1 as an anti-oxidation soy saucer. After the soy sauce is received from the mouth portion 14 of the container body 11, the ejection pump 21 is attached to the mouth portion 14. When the cap portion 43 of the ejection pump 21 is firmly tightened and screwed into the mouth portion 14 of the container main body 11, the taper portion of the ceiling surface 48 of the cap portion 43 and the tip of the mouth portion 14 of the container main body 11 come into contact with each other. The fluid can be prevented from entering and exiting from the contact point.
　噴出ポンプ２１を取付けた後は、噴出ユニット５１を押し込み容器本体１１の内側容器１２内、及び吸込ユニット３１の噴出経路５０内に残っている空気を排出させる。これにより内側容器１２内、及び吸込ユニット３１の噴出経路５０内は醤油で満たされ、第二逆止弁ユニット８２により外部の空気の侵入が防止されるので、収容されている醤油が酸化することはない。 After the ejection pump 21 is attached, the ejection unit 51 is pushed in, and the air remaining in the inner container 12 of the container body 11 and the ejection path 50 of the suction unit 31 is discharged. Thereby, the inside of the inner container 12 and the inside of the ejection path 50 of the suction unit 31 are filled with soy sauce, and the second check valve unit 82 prevents entry of external air, so that the soy sauce contained therein is oxidized. There is no.
　醤油を噴出するときは、噴出ユニット５１を押し込むと吸込ユニット３１の噴出経路５０内の容積が減少して昇圧され、吸込ユニット３１の第一逆止弁ユニット８１が閉弁し、噴出ユニット５１の第二逆止弁ユニット８２が開弁し、吸込ユニット３１の噴出経路５０内の醤油が第二逆止弁ユニット８２を通過し噴出ユニット５１の噴出経路７０を通って噴出口６１（スプレーノズル７３）より噴霧される。 When the soy sauce is ejected, when the ejection unit 51 is pushed in, the volume in the ejection path 50 of the suction unit 31 is reduced and the pressure is increased, the first check valve unit 81 of the suction unit 31 is closed, and the ejection unit 51 The second check valve unit 82 is opened, soy sauce in the jet path 50 of the suction unit 31 passes through the second check valve unit 82, passes through the jet path 70 of the jet unit 51, and the jet outlet 61 (spray nozzle 73 ) More sprayed.
　噴出ユニット５１を押し込むのをやめると、バネ７１の弾性力により噴出ユニット５１が持ち上げられる。このとき吸込ユニット３１の噴出経路５０内の容積が増大して減圧され、噴出ユニット５１の第二逆止弁ユニット８２が閉弁し、吸込ユニット３１の第一逆止弁ユニット８１が開弁し、内側容器１２内の醤油が第一逆止弁ユニット８１を通過し、吸込ユニット３１の噴出経路５０内に充填される。このとき内側容器１２は、吸込ユニット３１の噴出経路５０へ流出した醤油の容積分、減容し収縮する。なお醤油の噴霧を繰り返すと徐々に内側容器１２が収縮するが、ポンプ容器１は、外側容器１３により常に自立可能である。 When the ejection unit 51 is stopped from being pushed in, the ejection unit 51 is lifted by the elastic force of the spring 71. At this time, the volume in the ejection path 50 of the suction unit 31 is increased and the pressure is reduced, the second check valve unit 82 of the ejection unit 51 is closed, and the first check valve unit 81 of the suction unit 31 is opened. The soy sauce in the inner container 12 passes through the first check valve unit 81 and fills the ejection path 50 of the suction unit 31. At this time, the inner container 12 is reduced in volume and contracted by the volume of the soy sauce that has flowed into the ejection path 50 of the suction unit 31. When the spraying of soy sauce is repeated, the inner container 12 gradually contracts, but the pump container 1 can always stand by the outer container 13.
　ポンプ容器１の使用中は、第二逆止弁ユニット８２により外部の空気の侵入が防止されるので、内側容器１２内、及び吸込ユニット３１の噴出経路５０内の醤油が酸化されることがない。また第二逆止弁ユニット８２は、閉弁時には負圧による作用に加え、基台８３とフィルム８７との隙間に介在する醤油の毛管吸引力とによりフィルム８７が基台８３の上面に素早く密着して逆止弁が閉弁されるので、シール性が良く、空気の侵入を確実に防止することができる。 While the pump container 1 is in use, the second check valve unit 82 prevents outside air from entering, so that the soy sauce in the inner container 12 and the ejection path 50 of the suction unit 31 is not oxidized. . Further, the second check valve unit 82 quickly adheres to the upper surface of the base 83 by the capillary suction force of soy sauce interposed in the gap between the base 83 and the film 87 in addition to the action due to the negative pressure when the valve is closed. Since the check valve is closed, the sealing performance is good and air can be reliably prevented from entering.
　以上のように第１実施形態のポンプ容器１の噴出ポンプ２１に用いる逆止弁ユニット８１、８２は、構造が簡単でありながら鋼球や可動片等の部品を用いる他の逆止弁に比べて可動範囲が微小であり信頼性が高い。またフィルムにより弁孔を開閉するタイプの逆止弁では、フィルムが噛み込まれ等により変形したり損傷したりするとシール性が損なわれるが、本実施形態で用いる逆止弁ユニット８１、８２は、取付部８６が弁部８５と重複しない領域に設けられているので、噴出ポンプ２１への取付時にフィルム８７が噛み込まれる恐れがない。 As described above, the check valve units 81 and 82 used for the jet pump 21 of the pump container 1 according to the first embodiment are simple in structure but compared with other check valves using parts such as steel balls and movable pieces. The movable range is very small and the reliability is high. In addition, in a check valve of a type that opens and closes a valve hole with a film, the sealing performance is impaired when the film is bitten and deformed or damaged, but the check valve units 81 and 82 used in this embodiment are Since the attachment portion 86 is provided in a region that does not overlap with the valve portion 85, there is no possibility that the film 87 is bitten when attached to the ejection pump 21.
　このように噴出ポンプ２１に逆止弁ユニット８１、８２を用いると容易に製造可能な低コストでコンパクト且つ高品質な噴出ポンプ２１を得ることができる。さらには、逆止弁ユニット８１、８２を用いた噴出ポンプ２１を備えるポンプ容器１は、低コストでコンパクト且つ高品質に製造することができる。 As described above, when the check valve units 81 and 82 are used for the ejection pump 21, the ejection pump 21 can be easily manufactured at a low cost with a compact and high quality. Furthermore, the pump container 1 including the jet pump 21 using the check valve units 81 and 82 can be manufactured at low cost in a compact and high quality.
　次に本発明の噴出ポンプに用いる逆止弁ユニットの変形例を示す。図５から図７は、逆止弁ユニットの変形例を示す図である。第１実施形態の注出容器１に用いた逆止弁ユニット８１、８２と同一の構成には同一の符号を付して説明を省略する。図５から図７に示される逆止弁ユニットの材質は、逆止弁ユニット８１、８２と同様に考えればよい。 Next, a modified example of the check valve unit used in the ejection pump of the present invention will be shown. 5 to 7 are views showing modifications of the check valve unit. The same components as those of the check valve units 81 and 82 used in the dispensing container 1 of the first embodiment are denoted by the same reference numerals and description thereof is omitted. The material of the check valve unit shown in FIGS. 5 to 7 may be considered similarly to the check valve units 81 and 82.
　図５（ａ）は、基台８３ａの上面に凸部１０１を有する逆止弁ユニット１００ａの断面図である。該逆止弁ユニット１００ａは、被取付部の内径と略同一の外径を有する位置決め用の凸部１０１を基台８３ａの上面に備え、取付時に凸部１０１が被取付部に隙間なく嵌め込まれて位置決めされる。このため該逆止弁ユニット１００ａは、取付けが容易であるとともに、取付部８６を被取付部に確実に当接させることができ、フィルム８７の噛み込みをより確実に防止することができる。なお取付方法によっては、凸部１０１を基台８３ａの下面に設けてもよく、上面及び下面の両方に設けてもよい。 FIG. 5A is a cross-sectional view of a check valve unit 100a having a convex portion 101 on the upper surface of the base 83a. The check valve unit 100a includes a positioning convex portion 101 having an outer diameter substantially the same as the inner diameter of the mounted portion on the upper surface of the base 83a, and the convex portion 101 is fitted into the mounted portion without a gap during mounting. Is positioned. For this reason, the check valve unit 100a can be easily mounted, and the mounting portion 86 can be surely brought into contact with the mounted portion, and the film 87 can be more reliably prevented from being caught. Depending on the attachment method, the convex portion 101 may be provided on the lower surface of the base 83a, or may be provided on both the upper surface and the lower surface.
　また図５（ａ）の逆止弁ユニット１００ａは、位置決め精度をさらに向上させるべく、基台８３ａの凸部１０１の外周面に突起（図示省略）を設け、被取付部の内周面に係合させてもよく、凸部１０１の外径を被取付部の内径よりも大きくして圧入するようにしてもよく、凸部１０１の外周面を被取付部の内周面に接着して取付けてもよく、凸部１０１の外周面と被取付部の内周面とに互いに螺合するねじ山（図示省略）や、互いに係合する凹凸部（図示省略）等を設けて直接、被取付部に連結させてもよい。また凸部１０１を被取付部の内周面に圧入又は接着する場合は、凸部の外周面を取付部としてシールするようにしてもよい。 In addition, the check valve unit 100a of FIG. 5A is provided with a protrusion (not shown) on the outer peripheral surface of the convex portion 101 of the base 83a so as to further improve the positioning accuracy, and is engaged with the inner peripheral surface of the mounted portion. The outer diameter of the convex portion 101 may be larger than the inner diameter of the attached portion and may be press-fitted, and the outer peripheral surface of the convex portion 101 is attached to the inner peripheral surface of the attached portion. It is also possible to directly attach the screw by providing a screw thread (not shown) that engages with the outer peripheral surface of the convex portion 101 and the inner peripheral surface of the attached portion, an uneven portion (not shown) that engages with each other, and the like. You may connect with a part. When the convex portion 101 is press-fitted or bonded to the inner peripheral surface of the attached portion, the outer peripheral surface of the convex portion may be sealed as the attaching portion.
　図５（ｂ）は、基台８３ｂの上面周縁部に段差部１０２を有する逆止弁ユニット１００ｂの断面図である。該逆止弁ユニット１００ｂは、基台８３ｂの上面周縁部に高さがフィルム８７の上面よりも高い段差部１０２が形成されており、段差部１０２の上面が取付部８６となり、段差部１０２が形成されていない領域に弁部８５を有する。該逆止弁ユニット１００ｂの取付時には、取付部８６が確実に被取付部に当接するので、フィルム８７が被取付部に接触する恐れがない。 FIG. 5B is a cross-sectional view of a check valve unit 100b having a stepped portion 102 at the upper peripheral edge of the base 83b. In the check valve unit 100b, a stepped portion 102 having a height higher than that of the upper surface of the film 87 is formed on the peripheral edge of the upper surface of the base 83b, and the upper surface of the stepped portion 102 serves as a mounting portion 86. It has the valve part 85 in the area | region which is not formed. When the check valve unit 100b is mounted, the mounting portion 86 is surely brought into contact with the mounted portion, so that there is no possibility that the film 87 contacts the mounted portion.
　図５（ｃ）は、基台８３の上面周縁部にリング１０３を有する逆止弁ユニット１００ｃの断面図である。該逆止弁ユニット１００ｃは、基台８３と、基台８３の直径と略同一の直径を有するフィルム８７ｃと、平板状のリング１０３とを備え、基台８３の上面周縁部とリング１０３の下面とがフィルム８７ｃを挟持した状態で接着されて構成される。該逆止弁ユニット１００ｃでは、基台８３の上面全体がフィルム８７ｃを重ねる弁部８５となり、基台８３の上面周縁部に代えて、リング１０３の上面が取付部８６となる。 FIG. 5C is a cross-sectional view of a check valve unit 100 c having a ring 103 on the peripheral edge of the upper surface of the base 83. The check valve unit 100 c includes a base 83, a film 87 c having a diameter substantially the same as the diameter of the base 83, and a flat ring 103, and an upper surface peripheral portion of the base 83 and a lower surface of the ring 103. Are bonded together with the film 87c sandwiched therebetween. In the check valve unit 100 c, the entire upper surface of the base 83 serves as a valve portion 85 that overlaps the film 87 c, and the upper surface of the ring 103 serves as a mounting portion 86 instead of the peripheral portion of the upper surface of the base 83.
　フィルム８７ｃには、吐出孔９０が穿設されており、フィルム８７ｃは、吐出孔９０が基台８３の弁孔８４に対して基台８３の中心を挟んで反対側に配置される向きで接着される。吐出孔９０の位置は、弁孔８４と重複していなければよく、特定の位置に限定されるものではない。また吐出孔９０の大きさ及び形状についても、特定のものに限定されるものではなく、例えば、フィルム８７ｃに部分的に切込みを入れたスリット孔としてもよい。 A discharge hole 90 is formed in the film 87c, and the film 87c is bonded in such a direction that the discharge hole 90 is disposed on the opposite side of the center of the base 83 with respect to the valve hole 84 of the base 83. Is done. The position of the discharge hole 90 is not limited to a specific position as long as it does not overlap with the valve hole 84. Further, the size and shape of the discharge hole 90 are not limited to a specific one. For example, the discharge hole 90 may be a slit hole obtained by partially cutting the film 87c.
　リング１０３は、厚さがフィルム８７ｃよりも厚く、上面が被取付部と当接する取付部８６となる。このため取付部８６がフィルム８７ｃの上面よりも高く、取付時には取付部８６が被取付部に確実に当接するので、フィルム８７ｃが被取付部に噛み込まれて変形又は損傷する恐れがない。リング１０３の材質は、基台８３と同様に考えればよい。 The ring 103 is thicker than the film 87c, and the upper surface serves as a mounting portion 86 that comes into contact with the mounted portion. For this reason, the attachment part 86 is higher than the upper surface of the film 87c, and the attachment part 86 reliably contacts the attached part at the time of attachment. Therefore, there is no possibility that the film 87c is caught in the attached part and deformed or damaged. The material of the ring 103 may be considered similarly to the base 83.
　図５（ｃ）の逆止弁ユニット１００ｃは、吐出孔９０が穿設されたストレッチフィルムを基台８３の上面全体に被せ、その上からリング１０３を基台８３に振動溶着や超音波溶着等で接着し、基台８３及びリング１０３の外径に沿ってストレッチフィルムを裁断する手順で容易に製造することができる。このようにリング１０３を用いると、リング１０３の接着と同時にフィルム８７ｃが吐出経路８９を確保した状態で接着される。ただし製造方法は、これに限定されるものではない。 The check valve unit 100c shown in FIG. 5C covers the entire upper surface of the base 83 with a stretch film in which a discharge hole 90 is formed, and the ring 103 is attached to the base 83 from above by vibration welding, ultrasonic welding, or the like. And can be easily manufactured by a procedure of cutting the stretch film along the outer diameter of the base 83 and the ring 103. When the ring 103 is used in this manner, the film 87 c is bonded in a state where the discharge path 89 is secured simultaneously with the bonding of the ring 103. However, the manufacturing method is not limited to this.
　またリング１０３の下面を吐出経路８９を確保可能な任意の形状とし、フィルム８７ｃを挟持して接着することで吐出経路８９を任意の経路に形成することができる。なおフィルム８７ｃを予め弁部８５において吐出経路８９を除いて接着してもよい。 Further, the discharge path 89 can be formed in an arbitrary path by forming the lower surface of the ring 103 into an arbitrary shape capable of securing the discharge path 89 and sandwiching and bonding the film 87c. The film 87c may be bonded in advance at the valve portion 85 except for the discharge path 89.
　またフィルム８７ｃは、挟持された状態で基台８３に接着されているが、これに限定されるものではなく、直径を小さくして挟持されていない状態で基台８３に接着されていてもよい。このときには、吐出孔９０が穿設されていないフィルム８７を用いて吐出口８８を形成するように接着されていてもよい。 The film 87c is bonded to the base 83 in a sandwiched state, but is not limited thereto, and may be bonded to the base 83 in a state where the film 87c is not sandwiched with a reduced diameter. . At this time, the discharge port 88 may be bonded by using a film 87 in which the discharge hole 90 is not formed.
　図５（ｄ）は、カバー１０４を備える逆止弁ユニット１００ｄの断面図である。該逆止弁ユニット１００ｄは、基台８３と、基台８３の直径と略同一の直径を有するフィルム８７ｄと、有頂円筒形状のカバー１０４とを備え、基台８３の上面周縁部とカバー１０４の円筒部の下面とがフィルム８７ｄを挟持した状態で接着されて構成される。また該逆止弁ユニット１００ｄの取付部は、基台８３の下面、基台８３の側面、カバー１０４の上面又はカバー１０４の側面のうち少なくともいずれか一つ以上の任意の領域に設けられる。 FIG. 5D is a cross-sectional view of the check valve unit 100 d provided with the cover 104. The check valve unit 100 d includes a base 83, a film 87 d having a diameter substantially the same as the diameter of the base 83, and a cover-shaped cylindrical cover 104. And the lower surface of the cylindrical portion are bonded together with the film 87d sandwiched therebetween. The mounting portion of the check valve unit 100d is provided in any region of at least one of the lower surface of the base 83, the side surface of the base 83, the upper surface of the cover 104, or the side surface of the cover 104.
　フィルム８７ｄは、平面視において円の一部を切り取った弓形であり、円弧に沿った周縁部が挟持及び接着され、弦にあたる部分が挟持及び接着されずに吐出口８８を形成する。吐出口８８を設ける位置は、弁孔８４と重複しない位置に適宜決めればよい。また吐出口８８は、フィルム８７ｄの弦の一部のみを接着せずに形成されていてもよい。 The film 87d has an arcuate shape obtained by cutting off a part of a circle in plan view, and a peripheral portion along the arc is sandwiched and bonded, and a portion corresponding to a string is not sandwiched and bonded to form a discharge port 88. What is necessary is just to determine suitably the position which provides the discharge port 88 in the position which does not overlap with the valve hole 84. FIG. Further, the discharge port 88 may be formed without adhering only a part of the string of the film 87d.
　カバー１０４は、頂部に設けられ内容物１０を排出する排出口１０５を備え、カバー１０４の天井面１０６の高さがフィルム８７ｄの上面よりも高くなるように円筒部の高さが設定される。カバー１０４の排出口１０５と基台８３の弁孔８４、フィルム８７ｄの吐出口８８との位置関係は、特定の位置に限定されるものではない。またカバー１０４の材質は、特定の材質に限定されるものではなく、基台８３と同様に適宜選択したものを使用することができる。 The cover 104 is provided with a discharge port 105 provided at the top for discharging the contents 10, and the height of the cylindrical portion is set so that the height of the ceiling surface 106 of the cover 104 is higher than the upper surface of the film 87d. The positional relationship between the discharge port 105 of the cover 104, the valve hole 84 of the base 83, and the discharge port 88 of the film 87d is not limited to a specific position. The material of the cover 104 is not limited to a specific material, and a material appropriately selected as in the base 83 can be used.
　図５（ｄ）の逆止弁ユニット１００ｄでは、フィルム８７ｄの上面が基台８３とカバー１０４とで囲まれているので、接触によるフィルム８７ｄの変形又は損傷の恐れがない。また逆止弁ユニット１００ｄは、噴出ポンプ１１に取付けられる際、フィルム８７ｄに人が触れることがないため衛生上も好ましい。さらにカバー１０４の円筒部の高さを適切に設定することで開弁時のフィルム８７ｄの過剰な浮き上がりを抑制し、損傷、残留ひずみによるシール性能の低下を防止することができる。 In the check valve unit 100d of FIG. 5D, since the upper surface of the film 87d is surrounded by the base 83 and the cover 104, there is no fear of deformation or damage of the film 87d due to contact. In addition, the check valve unit 100d is preferable in terms of hygiene because it prevents the person from touching the film 87d when it is attached to the ejection pump 11. Furthermore, by appropriately setting the height of the cylindrical portion of the cover 104, excessive lifting of the film 87d at the time of valve opening can be suppressed, and deterioration of the sealing performance due to damage and residual strain can be prevented.
　図５（ｄ）の逆止弁ユニット１００ｄは、フィルム８７ｄが弓形となるようにストレッチフィルムを基台８３の上面に一部を除いて被せ、その上からカバー１０４の円筒部の下面を基台８３に振動溶着や超音波溶着等で接着し、基台８３及びカバー１０４の外径に沿ってストレッチフィルムを裁断する手順で容易に製造することができる。このようにカバー１０４を用いると、カバー１０４の接着と同時にフィルム８７ｄが吐出経路８９を確保した状態で接着される。ただし製造方法は、これに限定されるものではない。 The check valve unit 100d shown in FIG. 5 (d) covers a stretch film on the upper surface of the base 83 except for a part so that the film 87d has a bow shape, and the lower surface of the cylindrical portion of the cover 104 is mounted on the base. It can be easily manufactured by the procedure of adhering to 83 by vibration welding, ultrasonic welding or the like, and cutting the stretch film along the outer diameter of the base 83 and the cover 104. When the cover 104 is used in this way, the film 87d is bonded in a state where the discharge path 89 is secured simultaneously with the bonding of the cover 104. However, the manufacturing method is not limited to this.
　またカバー１０４の下面を吐出経路８９を確保可能な任意の形状とし、フィルム８７ｃを挟持して接着することで吐出経路８９を任意の経路に形成することができる。なおフィルム８７ｄを予め弁部８５において吐出経路８９を除いて接着してもよい。 Further, the discharge path 89 can be formed in an arbitrary path by making the lower surface of the cover 104 have an arbitrary shape capable of securing the discharge path 89 and sandwiching and bonding the film 87c. The film 87d may be bonded in advance in the valve portion 85 except for the discharge path 89.
　なお図５（ｄ）の逆止弁ユニット１００ｄに使用するフィルムは、弓形のフィルム８７ｄに限定されるものではなく、例えば、円形のフィルム８７を用いてもよく、吐出孔９０が穿設されたフィルム８７ｃを用いてもよい。またフィルム８７ｄは、直径を小さくして円弧に沿った周縁部が挟持されずに基台８３に接着されていてもよい。 The film used for the check valve unit 100d in FIG. 5 (d) is not limited to the arcuate film 87d. For example, a circular film 87 may be used, and the discharge hole 90 is formed. The film 87c may be used. Further, the film 87d may be bonded to the base 83 without reducing the diameter so that the peripheral portion along the arc is sandwiched.
　図５（ｅ）は、カバー１０７を備える逆止弁ユニット１００ｅの断面図である。該逆止弁ユニット１００ｅは、カバー１０７を基台８３ｅに係合させて製造されている。基台８３ｅの側面及びカバー１０７の内周面には、互いに係合する凹部９１及び凸部１０８が設けられている。また吐出孔９０を有するフィルム８７ｃは、基台８３ｅの上面及び側面を被覆する大きさとなっている。このため基台８３ｅの上面及び側面は、全体がフィルム８７ｃを重ねる弁部８５となり、取付部を有しない。該逆止弁ユニット１００ｅの取付部は、基台８３ｅの下面、カバー１０７の下面、カバー１０７の上面又はカバー１０７の側面のうち少なくともいずれか一つ以上の任意の領域に設けられる。 FIG. 5 (e) is a cross-sectional view of a check valve unit 100 e provided with a cover 107. The check valve unit 100e is manufactured by engaging the cover 107 with the base 83e. On the side surface of the base 83e and the inner peripheral surface of the cover 107, a concave portion 91 and a convex portion 108 that are engaged with each other are provided. The film 87c having the discharge holes 90 is sized to cover the upper surface and side surfaces of the base 83e.

The check valve unit 100f is manufactured by engaging the film clamping tool 109 with the base 83f with the film 87c being sandwiched.
　フィルム挟持具１０９は、基台８３ｆが嵌り込むリング形状であり、基台８３ｆとでフィルム８７ｃを挟持するように基台８３ｆに取付けられる。なおフィルム挟持具１０９の形状は、特定の形状に限定されるものではなく、例えば、半円形状の部品２つで構成されていてもよく、リング状に連続している必要はない。フィルム挟持具１０９の材質は、基台８３と同様に考えればよい。 The film clamping tool 109 has a ring shape into which the base 83f is fitted, and is attached to the base 83f so as to sandwich the film 87c with the base 83f.

It engages in the state which clamped the peripheral part of the film 87c to the recessed part 91 of 83f.
　このとき基台８３ｆの側面及びフィルム挟持具１０９の内周面が傾斜しているので、フィルム挟持具１０９を基台８３ｆに嵌め込み易く、さらにフィルム８７ｃに適度な張力を加えながら嵌め込むことができ、フィルム８７ｃが皺になり難い。 At this time, since the side surface of the base 83f and the inner peripheral surface of the film clamping tool 109 are inclined, the film clamping tool 109 can be easily fitted into the base 83f, and can be fitted while applying an appropriate tension to the film 87c. The film 87c is unlikely to become wrinkles.
　また基台８３ｆとフィルム８７ｃとは、互いの一部が予め接着されていてもよく、基台８３ｆとフィルム挟持具１０９とは、係合されるとともに接着されていてもよい。 Further, a part of the base 83f and the film 87c may be bonded in advance, and the base 83f and the film holding tool 109 may be engaged and bonded.
　図５（ｆ）の逆止弁ユニット１００ｆでは、フィルム挟持具１０９を嵌め込むと同時に基台８３ｆの上面全体に吐出経路８９が形成される。なおフィルム８７ｃを予め弁部８５において吐出経路８９を除いて接着してもよい。 In the check valve unit 100f of FIG. 5 (f), the discharge path 89 is formed on the entire upper surface of the base 83f at the same time as the film clamping tool 109 is fitted. The film 87c may be bonded in advance at the valve portion 85 except for the discharge path 89.
　図６（ａ）は、内周面が傾斜していないフィルム挟持具１０９ａを有する逆止弁ユニット１００ｇの要部断面図である。このようにフィルム挟持具１０９ａ及び基台８３ｇは、内周面又は外周面が傾斜していなくてもよい。 FIG. 6A is a cross-sectional view of an essential part of a check valve unit 100g having a film clamping tool 109a whose inner peripheral surface is not inclined. As described above, the inner peripheral surface or the outer peripheral surface of the film clamping tool 109a and the base 83g may not be inclined.
　図６（ｂ）は、内周面に凸部のないフィルム挟持具１０９ｂを有する逆止弁ユニット１００ｈの要部断面図である。このようにフィルム挟持具１０９ｂ及び基台８３ｈは、内周面又は外周面に凹部又は凸部を有しない場合でも傾斜部の嵌め合いによりフィルム８７ｃを挟持した状態で互いに嵌め込むことができる。 FIG. 6B is a cross-sectional view of an essential part of a check valve unit 100h having a film clamping tool 109b having no protrusion on the inner peripheral surface. Thus, the film clamping tool 109b and the base 83h can be fitted into each other in a state where the film 87c is sandwiched by the fitting of the inclined portion even when the inner peripheral surface or the outer peripheral surface does not have the concave portion or the convex portion.
　図６（ｃ）及び図６（ｄ）は、基台８３ｉ、８３ｊの周縁部に受け部９２を有する逆止弁ユニット１００ｉ、１００ｊの要部断面図である。このように受け部９２を設けることでフィルム挟持具１０９ｃ、１０９ｄを受け部９２に突き当てて製造することができるので、製造が容易となる。またフィルム８７ｃが折込まれて挟持される箇所が増えるので、フィルム８７ｃの緩みや外れが起こり難くなる。 6 (c) and 6 (d) are cross-sectional views of main parts of the check valve units 100i and 100j having the receiving portions 92 at the peripheral portions of the bases 83i and 83j. By providing the receiving portion 92 in this manner, the film holding tools 109c and 109d can be abutted against the receiving portion 92 and manufactured, so that the manufacture becomes easy. In addition, since the number of places where the film 87c is folded and sandwiched increases, the film 87c is unlikely to loosen or come off.
　図６（ｅ）は、基台８３ｋとフィルム挟持具１０９ｅとでフィルム８７ｃを挟持し、側面において溶着される逆止弁ユニット１００ｋの要部断面図である。基台８３ｋ及びフィルム挟持具１０９ｅは、それぞれ互いに嵌合する凹部９１及び凸部１１０を有し、フィルム８７ｃを挟んだ状態で嵌合され、嵌合時の継ぎ目９３において全周に亘って溶着される。なお図６（ｅ）の逆止弁ユニット１００ｋでは、フィルム８７ｃも継ぎ目９３において溶着されるが、フィルム８７ｃの直径を小さくしフィルム８７ｃを継ぎ目９３において溶着しなくてもよい。 FIG. 6E is a cross-sectional view of a main part of the check valve unit 100k that sandwiches the film 87c between the base 83k and the film clamping tool 109e and is welded on the side surface. The base 83k and the film clamping tool 109e have a concave portion 91 and a convex portion 110 that are fitted to each other, are fitted with the film 87c sandwiched therebetween, and are welded over the entire circumference at the seam 93 at the time of fitting. The In the check valve unit 100k of FIG. 6E, the film 87c is also welded at the joint 93, but the diameter of the film 87c may be reduced and the film 87c may not be welded at the joint 93.
　基台８３ｋ及びフィルム挟持具１０９ｅの継ぎ目９３となる互いの周縁部には、段差が設けられており、該周縁部に溶着時に発生するバリの逃げ溝９４が形成される。逃げ溝９４の幅及び深さは、バリが逆止弁ユニット１００ｋの外形面から突出しないように設定される。なお逃げ溝９４は、特定の形状に限定されるものではなく、例えば、断面がＶ字状や半円状等でもよい。また逃げ溝９４（継ぎ目９３）の位置は、側面に限定されるものではなく、例えば、図６（ａ）の逆止弁ユニット１００ｇのように継ぎ目が下面に位置する場合においても逃げ溝を設け、バリの突出を防止するようにしてもよい。 Steps are provided at the peripheral portions of the base 83k and the seam 93 of the film holding tool 109e, and burr escape grooves 94 generated during welding are formed at the peripheral portions. The width and depth of the escape groove 94 are set so that the burr does not protrude from the outer surface of the check valve unit 100k. The escape groove 94 is not limited to a specific shape, and for example, the cross section may be V-shaped or semicircular. Further, the position of the relief groove 94 (seam 93) is not limited to the side surface. For example, the relief groove is provided even when the joint is located on the lower surface as in the check valve unit 100g in FIG. The burr may be prevented from protruding.
　図６（ｅ）に示すように、側面に位置する継ぎ目９３において逆止弁ユニット１００ｋの厚み方向には溶着せず周方向のみ溶着することで、溶解による寸法収縮が防止される。これにより基台８３ｋの下面及びフィルム挟持具１０９ｅの上面を取付部として逆止弁ユニット１００ｋを被取付部に取付ける際の寸法管理が容易となり、厚み方向の寸法ズレによるシール不良を防止することができる。なお図６（ａ）の逆止弁ユニット１００ｇのように継ぎ目が下面に位置する場合においても、継ぎ目において周方向にのみ溶着することで、寸法収縮が防止され、側面を取付部として逆止弁ユニットを取付ける際の被取付部とのシール不良を防止することができる。 As shown in FIG. 6 (e), dimensional shrinkage due to melting is prevented by welding only in the circumferential direction without welding in the thickness direction of the check valve unit 100k at the seam 93 positioned on the side surface. This facilitates dimensional management when the check valve unit 100k is attached to the attached portion with the lower surface of the base 83k and the upper surface of the film clamping tool 109e as the attachment portion, and can prevent seal failure due to dimensional deviation in the thickness direction. it can. Even when the seam is located on the lower surface as in the check valve unit 100g of FIG. 6A, the dimensional shrinkage is prevented by welding only in the circumferential direction at the seam, and the check valve is used with the side surface as the mounting portion. It is possible to prevent a seal failure with the attached portion when the unit is mounted.
　図６（ｆ）は、基台８３ｌ及びフィルム挟持具１０９ｆが種々の形状に形成された逆止弁ユニット１００ｌの要部断面図である。このように基台８３ｌの下面の形状は、特定の形状に限定されるものではなく、用途、機能、又は美観等に合わせて種々の形状とすることができる。またフィルム挟持具１０９ｆは、フィルム８７ｃの浮き上がりを防止するフィルム押え部を上部に備える他、側面の一部がくり抜かれており、下面が基台８３ｌの下面よりも突出している。 FIG. 6F is a cross-sectional view of a main part of the check valve unit 100l in which the base 83l and the film clamping tool 109f are formed in various shapes. As described above, the shape of the lower surface of the base 83l is not limited to a specific shape, and may be various shapes according to the application, function, aesthetics, or the like. The film clamping tool 109f includes a film holding portion for preventing the film 87c from being lifted on the upper portion, a part of the side surface is cut out, and the lower surface protrudes from the lower surface of the base 83l.
　またフィルム押え部は、上面がフィルム８７ｃの上面よりも高くなるように厚みを有し、図５（ｂ）の逆止弁ユニット１００ｂの段差部１０２と同様の作用効果を有する。このようにフィルム挟持具１０９ｆについても基台８３ｌと同様、特定の形状に限定されるものではなく、用途、機能、又は美観等に合わせて種々の形状とすることができる。 Further, the film pressing portion has a thickness such that the upper surface is higher than the upper surface of the film 87c, and has the same effect as the step portion 102 of the check valve unit 100b in FIG. As described above, the film clamping tool 109f is not limited to a specific shape, like the base 83l, and can have various shapes in accordance with the application, function, aesthetics, or the like.
　またフィルム挟持具１０９ｆのフィルム押え部を吐出経路８９を確保可能な任意の形状とし、フィルム８７ｃを挟持して係合することで吐出経路８９を任意の経路に形成することができる。 Further, the discharge path 89 can be formed in an arbitrary path by forming the film pressing portion of the film holding tool 109f in an arbitrary shape that can secure the discharge path 89 and sandwiching and engaging the film 87c.
　なお図６に示す逆止弁ユニットでは、吐出孔９０を有するフィルム８７ｃを用いたが、これに限定されるものではなく、例えば、他の変形例で用いた吐出孔９０を有しない円形フィルム８７や弓形フィルム８７ｄを用いてもよい。 In the check valve unit shown in FIG. 6, the film 87c having the discharge hole 90 is used. However, the present invention is not limited to this. For example, the circular film 87 having no discharge hole 90 used in other modified examples is used. Alternatively, an arcuate film 87d may be used.
　図７（ａ）は、基台８３ｍに葉脈状の溝９５を有する逆止弁ユニット１００ｍの平面図である。該逆止弁ユニット１００ｍは、基台８３ｍの上面の吐出経路８９となる部分に葉脈状の溝９５を備える。 FIG. 7A is a plan view of a check valve unit 100m having a vein-like groove 95 on the base 83m. The check valve unit 100m includes a leaf-shaped groove 95 in a portion that becomes the discharge path 89 on the upper surface of the base 83m.
　葉脈状の溝９５は、直線状の幹部９６と、幹部９６から分岐する複数の枝部９７とで構成され、吐出経路８９と並行に３本形成されている。枝部９７は、幹部９６から角度を付けて分岐されており、隣り合う幹部９６の枝部９７同士が互い違いになるように形成されている。溝９５の数や形状は、これに限定されるものではないが、逆止弁ユニット１００ｍの使用時に基台８３ｍの上面とフィルム８７との間に液体の内容物１０を介在させ易いように適宜決められる。溝９５の深さは、深すぎると液体の内容物１０の入換えが難くなるため必要以上に深くすべきではない。 The vein-shaped groove 95 includes a straight trunk portion 96 and a plurality of branch portions 97 branched from the trunk portion 96, and three are formed in parallel with the discharge path 89. The branch portions 97 are branched from the trunk portion 96 at an angle, and are formed such that the branch portions 97 of the adjacent trunk portions 96 are staggered. The number and shape of the grooves 95 are not limited to this, but are appropriately set so that the liquid content 10 is easily interposed between the upper surface of the base 83m and the film 87 when the check valve unit 100m is used. It is decided. If the depth of the groove 95 is too deep, it is difficult to replace the liquid content 10, so it should not be deeper than necessary.
　図７（ａ）の逆止弁ユニット１００ｍでは、基台８３ｍの上面とフィルム８７との間に液体の内容物１０を介在させ易くする溝９５が基台８３ｍの上面の吐出経路８９となる部分に形成されているので、毛管吸引力を確実に働かせ、基台８３ｍの上面とフィルム８７との密着性を高めることができ、逆止弁のシール性能をより安定的に確保することができる。 In the check valve unit 100m of FIG. 7 (a), the groove 95 that facilitates the interposition of the liquid contents 10 between the upper surface of the base 83m and the film 87 becomes the discharge path 89 on the upper surface of the base 83m. Therefore, the capillary suction force can be reliably exerted, the adhesion between the upper surface of the base 83m and the film 87 can be improved, and the sealing performance of the check valve can be more stably ensured.
　図７（ｂ）は、基台８３ｎに吐出経路８９の全幅にまたがる溝９８を有する逆止弁ユニット１００ｎの平面図である。逆止弁ユニット１００ｎは、基台８３ｎの上面において吐出経路８９の全幅にまたがる溝９８を備える。 FIG. 7B is a plan view of a check valve unit 100n having a groove 98 extending over the entire width of the discharge path 89 in the base 83n. The check valve unit 100n includes a groove 98 extending over the entire width of the discharge path 89 on the upper surface of the base 83n.
　溝９８の深さや幅は、逆止弁ユニット１００ｎの使用時に液体の内容物１０を溝９８に常に滞留させることができるように適宜決められる。ただし溝９８の深さは、深すぎると液体の内容物１０の入換えが難くなるため、液体の内容物１０が常に滞留する深さで、かつ液体の内容物１０の入換えが円滑に行われる深さに適宜決められる。 The depth and width of the groove 98 are appropriately determined so that the liquid content 10 can always stay in the groove 98 when the check valve unit 100n is used. However, if the depth of the groove 98 is too deep, it becomes difficult to replace the liquid content 10, so that the liquid content 10 is always retained and the liquid content 10 can be replaced smoothly. The depth is determined as appropriate.
　図７（ｂ）の逆止弁ユニット１００ｎでは、液体の内容物１０を常に滞留させる溝９８が基台８３ｎの上面において吐出経路８９の全幅にまたがり形成されているので、毛管吸引力を確実に働かせ、基台８３ｎの上面とフィルム８７との密着性を高めることができ、逆止弁のシール性能を安定的に確保することができる。 In the check valve unit 100n of FIG. 7 (b), the groove 98 that always retains the liquid content 10 is formed across the entire width of the discharge path 89 on the upper surface of the base 83n, so that the capillary suction force can be ensured. Thus, the adhesion between the upper surface of the base 83n and the film 87 can be improved, and the sealing performance of the check valve can be stably secured.
　図７に示す逆止弁ユニット１００ｍ、１００ｎでは、基台の上面とフィルムとの間に液体の内容物を介在させ易いように基台の上面に溝を設けたが、溝の形状は、特定の形状に限定されるものではなく、例えば丸印や×印等の溝を設けてもよい。また溝ではなく、表面を荒らす、又は表面に小さな凹凸を設けることで同様の効果を得ることもできる。 In the check valve units 100m and 100n shown in FIG. 7, a groove is provided on the upper surface of the base so that the liquid contents are easily interposed between the upper surface of the base and the film. For example, a groove such as a circle or a cross may be provided. Further, the same effect can be obtained by roughening the surface instead of the groove or providing small irregularities on the surface.
　図８は、本発明の第２実施形態のポンプ容器２の断面図である。図１に示す第１実施形態のポンプ容器１と同一の構成には同一の符号を付して説明を省略する。第２実施形態のポンプ容器２は、第１実施形態のポンプ容器１と基本的構成は同じであるが、第二逆止弁ユニット８２の配置が異なる。 FIG. 8 is a cross-sectional view of the pump container 2 according to the second embodiment of the present invention. The same components as those of the pump container 1 of the first embodiment shown in FIG. The pump container 2 of the second embodiment has the same basic configuration as the pump container 1 of the first embodiment, but the arrangement of the second check valve unit 82 is different.
　第２実施形態のポンプ容器２では、スプレーノズル７３に代えて第二逆止弁ユニット８２が噴出口６１の先端に取付けられている。このとき第二逆止弁ユニット８２は、取付部８６が、基台８３の下面周縁部となり、取付部８６を介して噴出口６１の先端面に接着されている。 In the pump container 2 of the second embodiment, a second check valve unit 82 is attached to the tip of the ejection port 61 instead of the spray nozzle 73. At this time, in the second check valve unit 82, the attachment portion 86 becomes the lower surface peripheral portion of the base 83 and is bonded to the distal end surface of the ejection port 61 via the attachment portion 86.
　第二逆止弁ユニット８２を噴出口６１の先端に配置すると、内側容器１２内及び吸込ユニット３１の噴出経路５０内のみならず噴出ユニット５１の噴出経路７０内にも外部の空気が侵入しないので、注出容器２内の全ての未使用の内容物１０の酸化を防止することができる。 If the second check valve unit 82 is disposed at the tip of the jet outlet 61, external air does not enter not only the inside of the inner container 12 and the jet path 50 of the suction unit 31, but also the jet path 70 of the jet unit 51. The oxidation of all unused contents 10 in the dispensing container 2 can be prevented.
　なお第２実施形態のポンプ容器２では、スプレーノズルを用いていないが、例えば、スプレーノズルと噴出口６１の先端面とで第二逆止弁ユニット８２を挟み込んだ状態でスプレーノズルと噴出口６１とを連結して第二逆止弁ユニット８２を取付けることもできる。この場合には、第二逆止弁ユニット８２の上面周縁部及び下面周縁部を取付部８６とし、取付部８６を介して取付けることでフィルム８７の噛み込みを回避することができる。 In the pump container 2 of the second embodiment, the spray nozzle is not used. For example, the spray nozzle and the jet port 61 in a state where the second check valve unit 82 is sandwiched between the spray nozzle and the tip surface of the jet port 61. And the second check valve unit 82 can be attached. In this case, the upper surface peripheral portion and the lower surface peripheral portion of the second check valve unit 82 serve as the attachment portion 86, and the attachment of the film 87 through the attachment portion 86 can avoid the biting of the film 87.
　図９は、本発明に係る逆止弁ユニットの変形例を示す図である。第一逆止弁ユニット８１及び第二逆止弁ユニット８２と同一の構成には同一の符号を付して説明を省略する。第２実施形態のポンプ容器２のように第二逆止弁ユニット８２を噴出口６１の先端に配置して使用する場合には、上面から突出した排出口を有するカバーを備える逆止弁ユニットを好適に用いることができる。図９に示される逆止弁ユニットの材質は、他の逆止弁ユニットと同様に考えればよい。 FIG. 9 is a view showing a modification of the check valve unit according to the present invention. The same components as those of the first check valve unit 81 and the second check valve unit 82 are denoted by the same reference numerals, and description thereof is omitted. When the second check valve unit 82 is used at the tip of the jet outlet 61 as in the pump container 2 of the second embodiment, a check valve unit including a cover having a discharge port protruding from the upper surface is used. It can be used suitably. The material of the check valve unit shown in FIG. 9 may be considered in the same manner as other check valve units.
　図９（ａ）は、上面から突出した排出口１２２を有するカバー１２１ａを備える逆止弁ユニット１２０ａの断面図である。該逆止弁ユニット１２０ａは、図５（ｄ）の逆止弁ユニット１００ｄと構成は同様であるが、有頂円筒形状のカバー１２１ａに排出口１２２が上面から突出するように形成されている。このように排出口１２２を設けると内容物１０がスムーズに噴出されるため使い勝手が良い。 FIG. 9A is a cross-sectional view of a check valve unit 120a including a cover 121a having a discharge port 122 protruding from the upper surface. The check valve unit 120a has the same configuration as the check valve unit 100d shown in FIG. 5D, but is formed in a top cylindrical cover 121a so that the discharge port 122 protrudes from the upper surface. When the discharge port 122 is provided in this way, the contents 10 are smoothly ejected, which is convenient.
　図９（ｂ）は、上面から突出した排出口１２２を有するカバー１２１ｂを備える逆止弁ユニット１２０ｂの断面図である。該逆止弁ユニット１２０ｂは、カバー１２１ｂの外径が基台８３の外径よりも小さく、基台８３の上面周縁部及び下面周縁部が取付部８６となる。このように取付部８６を設けると、例えば、基台８３を噴出口６１の先端面とで挟持した状態で噴出口６１に連結される取付具（図示省略）等を用意して、基台８３の取付部８６（上面周縁部及び下面周縁部）を介して逆止弁ユニット１２０ｂを噴出口６１の先端面に取付けることもできる。 FIG. 9B is a cross-sectional view of a check valve unit 120b including a cover 121b having a discharge port 122 protruding from the upper surface. In the check valve unit 120 b, the outer diameter of the cover 121 b is smaller than the outer diameter of the base 83, and the upper surface peripheral portion and the lower surface peripheral portion of the base 83 serve as the attachment portion 86. When the mounting portion 86 is provided in this way, for example, a mounting tool (not shown) connected to the ejection port 61 in a state where the base 83 is sandwiched between the distal end surface of the ejection port 61 is prepared. The check valve unit 120b can also be attached to the distal end surface of the jet outlet 61 via the attachment portion 86 (upper peripheral portion and lower peripheral portion).
　図９（ｃ）は、上面から突出した排出口１２２を有するカバー１２１ｃを備える逆止弁ユニット１２０ｃの断面図である。該逆止弁ユニット１２０ｃは、基台１２３が有頂円筒形状であり、円筒部の内周面に雌ねじ１２４が設けられている。このような逆止弁ユニット１２０ｃは、噴出口６１の外周面に雌ねじ１２４が螺合する雄ねじ（図示省略）を設けることで、直接、噴出口６１の先端に取付けることができる。 FIG. 9C is a cross-sectional view of a check valve unit 120c including a cover 121c having a discharge port 122 protruding from the upper surface. In the check valve unit 120c, the base 123 has a cylindrical shape with a top, and an internal thread 124 is provided on the inner peripheral surface of the cylindrical portion. Such a check valve unit 120 c can be directly attached to the tip of the jet port 61 by providing a male screw (not shown) in which the female screw 124 is screwed onto the outer peripheral surface of the jet port 61.
　図９（ｄ）は、排出口１２２を有するカバー１２１ｄを備え、弁部８５と取付部８６とが直交した配置の逆止弁ユニット１２０ｄの断面図である。図９（ｅ）は、図９（ｄ）の逆止弁ユニット１２０ｄの平面図である。該逆止弁ユニット１２０ｄの基台１２５とカバー１２１ｄとは、互いに重ね合わせたときに円柱となる形状であり、互いに重ね合わせてフィルム１２６を挟持した状態で接着されている。逆止弁ユニット１２０ｄは、一端が斜めに切断されており、斜めに切断された方に排出口１２２が形成され、排出口１２２が外向きになるように噴出口６１の先端に取付けられる。 FIG. 9D is a cross-sectional view of a check valve unit 120d provided with a cover 121d having a discharge port 122 and in which the valve portion 85 and the mounting portion 86 are orthogonal to each other. FIG. 9 (e) is a plan view of the check valve unit 120d of FIG. 9 (d). The base 125 and the cover 121d of the check valve unit 120d have a cylindrical shape when they are overlapped with each other, and are bonded to each other with the film 126 sandwiched therebetween. One end of the check valve unit 120d is cut obliquely, a discharge port 122 is formed on the side cut diagonally, and the check valve unit 120d is attached to the tip of the jet port 61 so that the discharge port 122 faces outward.
　さらに基台１２５とカバー１２１ｄとは、外周方向に一定の厚みを持った係止部１２７、１２８が互いに重ね合わせたときに連続するようにそれぞれの外周面に設けられており、係止部１２７、１２８の上面及び／又は下面が取付部８６となる。例えば、第２実施形態のポンプ容器２に用いる場合、逆止弁ユニット１２０ｄは、係止部１２７、１２８の下面が取付部８６となり、取付部８６を介して噴出口６１の先端面に接着される。 Further, the base 125 and the cover 121d are provided on the outer peripheral surfaces so that the locking portions 127 and 128 having a certain thickness in the outer peripheral direction are continuous when they are overlapped with each other. , 128 serves as the attachment portion 86. For example, when used for the pump container 2 of the second embodiment, the check valve unit 120d is attached to the distal end surface of the jet port 61 via the mounting portion 86, with the lower surfaces of the locking portions 127 and 128 serving as the mounting portion 86. The
　基台１２５は、カバー１２１ｄとの重ね合せ面１２９を有し、該重ね合せ面１２９に弁部８５が設けられ、該重ね合せ面１２９の上部を除いた周縁部においてフィルム１２６及びカバー１２１ｄが接着される。また基台１２５には、弁孔８４が係止部１２７よりも下方に穿設されている。 The base 125 has an overlapping surface 129 with the cover 121d, the valve surface 85 is provided on the overlapping surface 129, and the film 126 and the cover 121d are bonded to each other at the peripheral portion excluding the upper portion of the overlapping surface 129. Is done. In addition, a valve hole 84 is formed in the base 125 below the locking portion 127.
　カバー１２１ｄにおいて基台１２５の重ね合せ面１２９に接着される面には、吐出経路８９を形成可能なように、基台１２５の上部を除いた周縁部に接着される一定幅でコ字状の接着代１３０を残して溝１３１が形成されている。また溝１３１の先端が排出口１２２となる。なお溝１３１の深さは、開弁時のフィルム１２６の過剰な浮き上がりを抑制可能に適宜決められる。 A surface of the cover 121d that is bonded to the overlapping surface 129 of the base 125 has a constant width and a U-shape that is bonded to the peripheral edge except for the upper portion of the base 125 so that a discharge path 89 can be formed. A groove 131 is formed leaving the bonding margin 130. Further, the tip of the groove 131 becomes the discharge port 122. Note that the depth of the groove 131 is determined as appropriate so as to suppress excessive lifting of the film 126 when the valve is opened.
　フィルム１２６は、基台１２５の重ね合せ面１２９と略同一の矩形状であり、基台１２５の周縁部とカバー１２１ｄの接着代１３０とで挟持されて接着される。このためフィルム１２６は、取付部８６と直交する向きに配置される。またフィルム１２６は、上辺が接着されずに吐出口８８を形成するとともに、接着と同時に弁孔８４から吐出口８８へ流体が流通可能に吐出経路８９を形成する。 The film 126 has a rectangular shape substantially the same as the overlapping surface 129 of the base 125, and is sandwiched and bonded by the peripheral edge of the base 125 and the bonding margin 130 of the cover 121d. For this reason, the film 126 is disposed in a direction orthogonal to the attachment portion 86.

The same components as those in the pump container 4 of the fourth embodiment shown in FIG. The pump container 5 of the fifth embodiment is a pump container that ejects the contents 10 in the form of foam, and uses a rod-shaped valve body 201 instead of the first check valve unit 81. Accordingly, the structure of the suction unit 34 and the ejection unit 54 of the ejection pump 24 is different from that of the ejection pump 23 of the pump container 4 of the fourth embodiment. Each member may be considered similarly to the pump container of the other embodiments.
　棒状弁体２０１は、上端に上端弁部２０２、下端に下端弁部２０３を備える棒状の弁体であり、公知のものを用いることができる。上端弁部２０２及び下端弁部２０３は、共にテーパ面２０４、２０５を有し、テーパ面２０４、２０５が噴出ユニット５４の弁座２１１又は吸込ユニット３４の弁座２１２に当接してシールを行う。また下端弁部２０３には、バネ７２を受ける受け部２０６が形成されている。 The rod-shaped valve body 201 is a rod-shaped valve body having an upper end valve portion 202 at the upper end and a lower end valve portion 203 at the lower end, and a known one can be used. Both the upper end valve portion 202 and the lower end valve portion 203 have tapered surfaces 204 and 205, and the tapered surfaces 204 and 205 abut against the valve seat 211 of the ejection unit 54 or the valve seat 212 of the suction unit 34 to perform sealing. The lower end valve portion 203 is formed with a receiving portion 206 that receives the spring 72.
　吸込ユニット３４は、第４実施形態のポンプ容器４の吸込ユニット３３と同様の構造であるが、内側円筒部２１３が棒状弁体２０１の長さに合わせて長くなっており、内側円筒部２１３の下端内周部に棒状弁体２０１の下端弁部２０３のテーパ面２０５と同程度の傾斜角を有する弁座２１２を備える。 The suction unit 34 has the same structure as the suction unit 33 of the pump container 4 of the fourth embodiment. However, the inner cylindrical portion 213 is elongated according to the length of the rod-shaped valve body 201, and the inner cylindrical portion 213 A valve seat 212 having an inclination angle similar to that of the tapered surface 205 of the lower end valve portion 203 of the rod-shaped valve body 201 is provided on the lower end inner peripheral portion.
　噴出ユニット５４は、第４実施形態のポンプ容器４の噴出ユニット５３と同様の構造であるが、内側円筒部２１４の内周面に棒状弁体２０１の上端弁部２０２のテーパ面２０４と同程度の傾斜角を有する弁座２１１を備える。 The ejection unit 54 has the same structure as that of the ejection unit 53 of the pump container 4 of the fourth embodiment, but is approximately the same as the tapered surface 204 of the upper end valve portion 202 of the rod-shaped valve body 201 on the inner peripheral surface of the inner cylindrical portion 214. A valve seat 211 having an inclination angle of
　容器本体２０の内側容器２９の胴部は、可撓性及び／又は柔軟性を有する素材で形成されており、内容物１０の減少に伴いながら吸込ユニット３４の内側円筒部２１３の外形に沿って収縮し、内容物１０を最後まで排出させることができる。 The body portion of the inner container 29 of the container body 20 is formed of a material having flexibility and / or flexibility, and follows the outer shape of the inner cylindrical portion 213 of the suction unit 34 while the content 10 decreases. It shrinks and the contents 10 can be discharged to the end.
　なお容器本体に蛇腹構造の内側容器を用いる場合は、口部１４の根元の高さが吸込ユニット３４の内側円筒部２１３の先端（吸込口４１）の高さよりも低くなるように、口部１４の高さ及び／又は吸込ユニット３４のキャップ部４３の高さを設定することで、蛇腹を最後まで収縮させることができる。 When an inner container having a bellows structure is used for the container main body, the mouth portion 14 is set so that the height of the base of the mouth portion 14 is lower than the height of the tip (suction port 41) of the inner cylindrical portion 213 of the suction unit 34. By setting the height and / or the height of the cap portion 43 of the suction unit 34, the bellows can be contracted to the end.
　このように構成される第５実施形態のポンプ容器５は、棒状弁体２０１が第４実施形態のポンプ容器４の第一逆止弁ユニット８１の機能を果たし、第４実施形態のポンプ容器４と同様の動作により内容物１０を泡状にして噴出させる。 In the pump container 5 of the fifth embodiment configured as described above, the rod-like valve body 201 functions as the first check valve unit 81 of the pump container 4 of the fourth embodiment, and the pump container 4 of the fourth embodiment. The content 10 is made to be foamed and ejected by the same operation as.
　このように噴出ポンプに用いる全ての逆止弁を逆止弁ユニットとせず、用途に応じて異なるタイプの逆止弁を用いることもできる。 Thus, not all the check valves used for the ejection pump are made a check valve unit, and different types of check valves can be used depending on the application.
　以上、第１から第５実施形態のポンプ容器を用いて、本発明の噴出ポンプ及び該噴出ポンプを有するポンプ容器を説明したが、本発明の噴出ポンプ及び該噴出ポンプを有するポンプ容器は、上記実施形態に限定されるものではなく、要旨を変更しない範囲で変形して使用することができる。例えば上記実施形態では逆止弁ユニットの基台、フィルム、リング及びカバーは、それぞれ互いに振動溶着等で接着したが、これに限定されるものではなく、接着剤等を用いて接着してもよい。 As mentioned above, although the pump container of this invention and the pump container which has this jet pump were demonstrated using the pump container of 1st to 5th embodiment, the pump container of this invention and the pump container which has this jet pump are the above-mentioned. The present invention is not limited to the embodiment, and can be used by being modified without changing the gist. For example, in the above embodiment, the base, the film, the ring, and the cover of the check valve unit are bonded to each other by vibration welding or the like, but are not limited thereto, and may be bonded using an adhesive or the like. .
　逆止弁ユニットの取付部は、特定の領域に限定されるものではなく、弁部とは重複しない領域で基台、リング、フィルム挟持具、カバーの任意の領域に設けることができる。例えば、第１から第５実施形態のポンプ容器１、２、３、４、５で使用した逆止弁ユニットは、側面を取付部８６として被取付部に取付けるようにしてもよい。 The mounting portion of the check valve unit is not limited to a specific area, and can be provided in any area of the base, the ring, the film clamping tool, and the cover in an area that does not overlap with the valve part. For example, the check valve unit used in the pump containers 1, 2, 3, 4, and 5 of the first to fifth embodiments may be attached to the mounted portion with the side surface as the mounting portion 86.
　逆止弁ユニットの基台、フィルム、リング、フィルム挟持具、カバー、容器本体の口部の形状は、円形に限定されるものではなく、例えば矩形や三角形、紡錘形等であってもよく、吸込ユニットや噴出ユニットの形状に合わせて適宜決めることができる。またそれぞれが同一形状である必要はなく、例えば基台が円形でカバーが矩形であってもよい。 The shape of the base of the check valve unit, the film, the ring, the film clamping tool, the cover, and the mouth of the container body is not limited to a circle, and may be, for example, a rectangle, a triangle, a spindle, etc. It can be determined appropriately according to the shape of the unit or the ejection unit. Moreover, it is not necessary for each to be the same shape, for example, a base may be circular and a cover may be a rectangle.
　逆止弁ユニットのカバーの排出口の形状も特定の形状に限定されるものではなく、カバーの形状に関係なく、例えば矩形や三角形等であってもよく、用途に応じて適宜決めることができる。 The shape of the discharge port of the check valve unit cover is not limited to a specific shape, and may be, for example, a rectangle or a triangle regardless of the shape of the cover, and can be appropriately determined according to the application. .
　また楕円形の逆止弁ユニットを用いて、斜めに切断された形状の被取付部に取付けることもできる。さらに途中に傾斜面を有する流路（図示省略）に逆止弁ユニットを取付ける場合は、該傾斜面と同一の角度で基台の上面又は側面を傾斜させ、該傾斜面に上面又は側面を取付部として接着してもよい。このように逆止弁ユニットは、被取付部に応じて、フィルムが噛み込まれない範囲で種々の変形を施して用いることができる。 Also, an elliptical check valve unit can be used to attach to the mounted part that is cut obliquely. Furthermore, when installing a check valve unit in a channel (not shown) having an inclined surface in the middle, the upper surface or side surface of the base is inclined at the same angle as the inclined surface, and the upper surface or side surface is attached to the inclined surface. You may adhere as a part. As described above, the check valve unit can be used with various modifications depending on the attached portion within a range in which the film is not caught.
　また図９（ｃ）の逆止弁ユニット１２０ｃでは、基台１２３と、噴出口６１とを連結する方法として螺合を用いたが、連結方法は螺合に限定されるものではない。例えばスナップフィットのように互いに係合する凹凸部、爪、又はその他の係止手段を設けて係合させてもよい。要するに逆止弁ユニットの基台と噴出口とを連結する方法は、逆止弁ユニットの基台と噴出口の先端面との気密性を確保することができるように互いをしっかりと連結することができればよい。 Further, in the check valve unit 120c of FIG. 9C, screwing is used as a method of connecting the base 123 and the jet port 61, but the connecting method is not limited to screwing. For example, an uneven portion, a claw, or other locking means that engage with each other like a snap fit may be provided and engaged. In short, the method of connecting the base of the check valve unit and the spout is to firmly connect the base of the check valve unit and the tip of the spout so that airtightness can be secured. If you can.
　逆止弁ユニットのフィルムの吐出口又は吐出孔と、カバーの排出口との位置関係は、特定の位置に限定されるものではないが、排出口が下側に位置するように逆止弁ユニットを噴出口の先端に取付ける場合、排出口を吐出口又は吐出孔に対して基台の中心を挟んで反対側に配置しておくと、内容物の排出時に吐出口又は吐出孔が基台の弁孔よりも常に高い位置となる。このようにすると、基台上面の流路に空気が侵入しても上方の吐出口又は吐出孔の方へ向かうので、空気が弁孔まで到達し難く、好ましい。 The positional relationship between the film discharge port or discharge hole of the check valve unit and the cover discharge port is not limited to a specific position, but the check valve unit is positioned so that the discharge port is located on the lower side. If the discharge port is placed on the opposite side of the center of the base with respect to the discharge port or the discharge hole, the discharge port or the discharge hole will be attached to the base of the base when discharging the contents. It is always higher than the valve hole. If it does in this way, even if air penetrate | invades into the flow path of a base upper surface, since it goes to an upper discharge port or a discharge hole, it is difficult for air to reach | attain a valve hole, and it is preferable.
　また逆止弁ユニットのフィルムは、放射状に均一に張力を加えた状態で基台の上面に接着されると、シール不良の原因となる皺の生成が抑制され、好ましい。さらには、基台の上面をドーム状に形成すると、フィルムに張力を加えやすくなり、かつ張力がフィルムを基台に密着させる方向にも働くので、逆止弁のシール性能が向上し、好ましい。 Also, it is preferable that the check valve unit film is adhered to the upper surface of the base in a state where tension is evenly applied in a radial direction, because generation of wrinkles that causes a seal failure is suppressed. Furthermore, it is preferable to form the upper surface of the base in a dome shape because it is easy to apply tension to the film and the tension also works in the direction in which the film is brought into close contact with the base, improving the sealing performance of the check valve.
　本発明の噴出ポンプ及び該噴出ポンプを有するポンプ容器の材質は、用途、収容する内容物に応じて適宜選択して使用可能なことは既に記載した通りであるが、本発明の噴出ポンプ及びポンプ容器の形態が要旨を変更しない範囲で変更され、本発明の噴出ポンプ及びポンプ容器に他の部品が付加されたような場合でも、その部分の材質については、用途、収容する内容物に応じて適宜選択して使用すればよい。例えば、ポンプ容器において収容する液体が酸化することを防止するには、液体と接する全ての部材（含む部品）、あるいは主要部材を酸素遮断性に優れる材質とすればよい。なお、使用する材料は、所定の性能を満たせば安価で入手し易いことが好ましいことは改めて言うまでもない。 As described above, the material of the jet pump of the present invention and the pump container having the jet pump can be appropriately selected and used according to the use and contents to be stored. Even if the shape of the container is changed without changing the gist and other parts are added to the jet pump and the pump container of the present invention, the material of the part depends on the use and contents to be stored. What is necessary is just to select and use suitably. For example, in order to prevent the liquid contained in the pump container from being oxidized, all members (including parts) in contact with the liquid or main members may be made of a material having excellent oxygen barrier properties. Needless to say, it is preferable that the material to be used is inexpensive and easily available as long as it satisfies a predetermined performance.
　この他、技術的に矛盾しない範囲で各実施形態における特徴的な部分、構成を適宜組合せて使用してもよいことは言うまでもない。 In addition to this, it goes without saying that the characteristic portions and configurations in each embodiment may be used in appropriate combination within a technically consistent range.
