ポンプ部材６は、合成樹脂製である。図２に示すように、ポンプ部材６は、蛇腹状に形成され、伸縮することでその内部からエアを吸排可能であるポンプ本体部４４と、ポンプ本体部４４内と連通して、該ポンプ本体部４４からのエアを容器５内に噴出する円筒状噴出部４５と、から構成される。ポンプ本体部４４は、縦長であって、所定の外径を有する蛇腹状に形成される。ポンプ本体部４４は、軸方向に沿って伸縮自在である。ポンプ部材６のポンプ本体部４４が、カバー部材９の円筒状部４１内に配置される。ポンプ本体部４４の伸縮していない初期状態の軸方向に沿う長さ寸法と、カバー部材９の円筒状部４１の軸方向に沿う長さ寸法（高さ寸法）とは略同じである。 The pump member 6 is made of synthetic resin. As shown in FIG. 2, the pump member 6 communicates with the pump main body 44, which is formed in a bellows shape and can suck and discharge air from the inside by expanding and contracting, and the inside of the pump main body 44, and the pump main body. It is composed of a cylindrical ejection portion 45 that ejects air from the portion 44 into the container 5. The pump main body 44 is vertically long and is formed in a bellows shape having a predetermined outer diameter. The pump main body 44 is expandable and contractible along the axial direction. The pump main body 44 of the pump member 6 is arranged in the cylindrical portion 41 of the cover member 9. The length dimension along the axial direction of the pump main body 44 in the initial state in which it is not expanded and contracted is substantially the same as the length dimension (height dimension) along the axial direction of the cylindrical portion 41 of the cover member 9.

ポンプ本体部４４の外径は、円筒状噴出部４５の外径よりも相当大径である。円筒状噴出部４５の上端には、環状のストッパ部４７が一体的に接続される。ストッパ部４７の外径は、キャップ部材１６のポンプ用挿通孔１９の内径より大径である。円筒状噴出部４５が、キャップ部材１６のポンプ用挿通孔１９に挿通されて、容器５内に配置される。なお、ポンプ部材６の円筒状噴出部４５の下端は、容器５の円筒状ねじ部１３（キャップ部材１６）の下端よりも高い位置に配置される。 The outer diameter of the pump main body 44 is considerably larger than the outer diameter of the cylindrical ejection portion 45. An annular stopper portion 47 is integrally connected to the upper end of the cylindrical ejection portion 45. The outer diameter of the stopper portion 47 is larger than the inner diameter of the pump insertion hole 19 of the cap member 16. The cylindrical ejection portion 45 is inserted into the pump insertion hole 19 of the cap member 16 and arranged in the container 5. The lower end of the cylindrical ejection portion 45 of the pump member 6 is arranged at a position higher than the lower end of the cylindrical screw portion 13 (cap member 16) of the container 5.

そして、使用者が指でポンプ部材６のポンプ本体部４４の上面を押し込むと、ポンプ本体部４４が軸方向に沿って縮小することで、ポンプ本体部４４内のエアが、円筒状噴出部４５から容器５内の液体に向かって噴出される。そこで、容器５の円筒状部４１には、キャップ部材１６が緊密に螺合されているので、容器５内を容易に密閉状態にすることができる。その結果、ポンプ本体部４４から円筒状噴出部４５を経由して容器５内に噴出したエアにより、容器５内の液体に大きな空気圧を付与することができる。 Then, when the user pushes the upper surface of the pump main body 44 of the pump member 6 with a finger, the pump main body 44 contracts along the axial direction, so that the air in the pump main body 44 is discharged into the cylindrical ejection portion 45. Is ejected toward the liquid in the container 5. Therefore, since the cap member 16 is tightly screwed into the cylindrical portion 41 of the container 5, the inside of the container 5 can be easily sealed. As a result, a large air pressure can be applied to the liquid in the container 5 by the air ejected from the pump main body 44 via the cylindrical ejection portion 45 into the container 5.

一方、使用者がポンプ部材６のポンプ本体部４４から指を離すと、ポンプ本体部４４内に、容器５内から円筒状噴出部４５を介して空気が吸引されることで、ポンプ本体４４が復元する。ノズル部材７は、合成樹脂製である。図２に示すように、ノズル部材７は、上下方向に延びる縦ノズル部５２と、該縦ノズル部５２の上端から水平方向に延びる横ノズル部５３と、該横ノズル部５３の軸方向端部から下方に向かって延びる先端ノズル部５４と、から構成される。 On the other hand, when the user releases the finger from the pump main body 44 of the pump member 6, air is sucked into the pump main body 44 from the container 5 through the cylindrical ejection portion 45, so that the pump main body 44 is moved. Restore. The nozzle member 7 is made of synthetic resin. As shown in FIG. 2, the nozzle member 7 includes a vertical nozzle portion 52 extending in the vertical direction, a horizontal nozzle portion 53 extending in the horizontal direction from the upper end of the vertical nozzle portion 52, and an axial end portion of the horizontal nozzle portion 53. It is composed of a tip nozzle portion 54 extending downward from the top.

縦ノズル部５２と横ノズル部５３との間に屈曲自在な第１蛇腹部５６が設けられる。横ノズル部５３と先端ノズル部５４との間にも第２蛇腹部５７が設けられる。そして、横ノズル部５３は、第１蛇腹部５６を介して縦ノズル部５２の延在方向に対して様々な方向に屈曲可能となる。また、先端ノズル部５４は、第２蛇腹部５８を介して横ノズル部５３の延在方向に対して様々な方向に屈曲可能となる。しかも、第１及び第２蛇腹部５６、５７を備えているので、ノズル部材７の折り曲げ箇所でもその内径を一定にすることができ、容器５内の液体の吐出を妨げることはない。なお、本実施形態では、ノズル部材７に、第１及び第２蛇腹部５６、５７として２箇所設けているが、３箇所以上設けてもよい。 A flexible first bellows portion 56 is provided between the vertical nozzle portion 52 and the horizontal nozzle portion 53. A second bellows portion 57 is also provided between the lateral nozzle portion 53 and the tip nozzle portion 54. Then, the horizontal nozzle portion 53 can be bent in various directions with respect to the extending direction of the vertical nozzle portion 52 via the first bellows portion 56. Further, the tip nozzle portion 54 can be bent in various directions with respect to the extending direction of the lateral nozzle portion 53 via the second bellows portion 58. Moreover, since the first and second bellows portions 56 and 57 are provided, the inner diameter of the nozzle member 7 can be made constant even at the bent portion, and the discharge of the liquid in the container 5 is not hindered. In the present embodiment, the nozzle member 7 is provided with the first and second bellows portions 56 and 57 at two locations, but may be provided at three or more locations.

縦ノズル部５２の下端部は、容器５内でその底面に近接する位置に配置される。縦ノズル部５２は、そのキャップ部材１６のノズル用挿通孔２０内を経て、その上端部が内蓋部材８とカバー部材９との間に位置する。横ノズル部５３は、内蓋部材８とカバー部材９との間であって、内蓋部材８に設けたスリット部２８の上方付近を、該スリット部２８の延びる方向に沿って延びる。先端ノズル部５４は、内蓋部材８に設けたスリット部２８の一端部（開口部２６側とは反対側端部）内を挿通して、その先端吐出口が内蓋部材８から下方に突出される。なお、ノズル部材７の外径は、内蓋部材８に設けたスリット部２８の幅長よりも小さく設定され、その内径は、０．５ｍｍ〜１．５ｍｍの範囲内で適宜設定される。 The lower end of the vertical nozzle portion 52 is arranged in the container 5 at a position close to the bottom surface thereof. The vertical nozzle portion 52 passes through the nozzle insertion hole 20 of the cap member 16 and its upper end portion is located between the inner lid member 8 and the cover member 9. The horizontal nozzle portion 53 extends between the inner lid member 8 and the cover member 9 in the vicinity of the upper side of the slit portion 28 provided in the inner lid member 8 along the extending direction of the slit portion 28. The tip nozzle portion 54 is inserted through one end of the slit portion 28 provided in the inner lid member 8 (the end on the side opposite to the opening 26 side), and the tip discharge port protrudes downward from the inner lid member 8. Will be done. The outer diameter of the nozzle member 7 is set smaller than the width length of the slit portion 28 provided in the inner lid member 8, and the inner diameter thereof is appropriately set within the range of 0.5 mm to 1.5 mm.

そして、図１及び図２を参照して、本実施形態に係る液吐出装置１を組み立てる際には、まず、外容器４内に、内部に液体が貯溜された容器５を配置する。このとき、容器５の円筒状ねじ部１３には、予めキャップ部材１６が螺合された状態である。続いて、外容器４の上端開口上に内蓋部材８の矩形板状部２３が配置されるように、外容器４上に内蓋部材８を配置する。続いて、外容器４の上端開口の内側に内蓋部材８（矩形板状部２３）の角筒状嵌合部３１を互いに密着するように嵌合する。すると、外容器４の上端開口が内蓋部材８により閉塞されて組み付けられる。 Then, when assembling the liquid discharge device 1 according to the present embodiment with reference to FIGS. 1 and 2, first, a container 5 in which the liquid is stored is arranged in the outer container 4. At this time, the cap member 16 is previously screwed into the cylindrical threaded portion 13 of the container 5. Subsequently, the inner lid member 8 is arranged on the outer container 4 so that the rectangular plate-shaped portion 23 of the inner lid member 8 is arranged on the upper end opening of the outer container 4. Subsequently, the square tubular fitting portion 31 of the inner lid member 8 (rectangular plate-shaped portion 23) is fitted to the inside of the upper end opening of the outer container 4 so as to be in close contact with each other. Then, the upper end opening of the outer container 4 is closed by the inner lid member 8 and assembled.

次に、ノズル部材７の縦ノズル部５２を、内蓋部材８の開口部２６を介して、キャップ部材１６のノズル用挿通孔２０に挿通しつつ、横ノズル部５３を、内蓋部材８のスリット部２８上を該スリット部２８に沿って延びるように配置して、且つ先端ノズル部５４を、内蓋部材８のスリット部２８の一端部（開口部２６側とは反対側端部）内に挿通して組み付ける。 Next, while inserting the vertical nozzle portion 52 of the nozzle member 7 into the nozzle insertion hole 20 of the cap member 16 through the opening 26 of the inner lid member 8, the horizontal nozzle portion 53 is inserted into the inner lid member 8. The slit portion 28 is arranged so as to extend along the slit portion 28, and the tip nozzle portion 54 is placed in one end of the slit portion 28 of the inner lid member 8 (the end opposite to the opening 26 side). Insert it into and assemble it.

このとき、容器５の円筒状ねじ部１３に螺合されたキャップ部材１６のノズル用挿通孔２０が、内蓋部材８の半円板状部２４側に位置していない場合があるが、その際でも、ノズル部材７の縦ノズル部５２を、キャップ部材１６のノズル用挿通孔２０に挿通した後、横ノズル部５３を、第１蛇腹部５６を介してその先端が内蓋部材８のスリット部２８の一端部（開口部２６側とは反対側端部）に指向するように屈曲させることができる。さらに、先端ノズル部５４を、第２蛇腹部５７を介して自在に屈曲させて、その先端吐出口を、内蓋部材８のスリット部２８の一端部から下方に突出させることができる。 At this time, the nozzle insertion hole 20 of the cap member 16 screwed into the cylindrical screw portion 13 of the container 5 may not be located on the semi-disk-shaped portion 24 side of the inner lid member 8. Even in this case, after inserting the vertical nozzle portion 52 of the nozzle member 7 into the nozzle insertion hole 20 of the cap member 16, the horizontal nozzle portion 53 is inserted through the first bellows portion 56, and the tip thereof is a slit of the inner lid member 8. It can be bent so as to be directed toward one end of the portion 28 (the end opposite to the opening 26 side). Further, the tip nozzle portion 54 can be freely bent via the second bellows portion 57, and the tip discharge port thereof can be projected downward from one end of the slit portion 28 of the inner lid member 8.

次に、ポンプ部材６の円筒状噴出部４５を、内蓋部材８の開口部２６を介して、キャップ部材１６のポンプ用挿通孔１９に、ストッパ部４７がキャップ部材１６の天端部に当接するまで挿通して組み付ける。続いて、カバー部材９を内蓋部材８の全体を覆うようにして、カバー部材９の筒状被覆部３８を、内蓋部材８の筒状嵌合部３４の外側に互いに密着するように嵌合させつつ、カバー部材９の円筒状部４１内に、ポンプ部材６のポンプ本体部４４が配置されるように組み付ける。このとき、ポンプ部材６のポンプ本体部４４の上面が、カバー部材９の円筒状部４１の上端開口より上方に若干突出するようになる。そして、本実施形態に係る液吐出装置１の組み立てが完了する。 Next, the cylindrical ejection portion 45 of the pump member 6 is brought into contact with the pump insertion hole 19 of the cap member 16 via the opening 26 of the inner lid member 8, and the stopper portion 47 is in contact with the top end portion of the cap member 16. Insert and assemble until it touches. Subsequently, the cover member 9 is fitted so as to cover the entire inner lid member 8, and the tubular covering portion 38 of the cover member 9 is fitted to the outside of the tubular fitting portion 34 of the inner lid member 8 so as to be in close contact with each other. Assemble the cover member 9 so that the pump main body 44 of the pump member 6 is arranged in the cylindrical portion 41 of the cover member 9 while being fitted. At this time, the upper surface of the pump main body 44 of the pump member 6 slightly protrudes upward from the upper end opening of the cylindrical portion 41 of the cover member 9. Then, the assembly of the liquid discharge device 1 according to the present embodiment is completed.

そして、本実施形態に係る液吐出装置１において、容器５内の液体を外部に吐出する際には、使用者が指でポンプ部材６のポンプ本体部４４の上面を押し込む。すると、ポンプ本体部４４が軸方向に沿って縮小することで、ポンプ本体部４４内のエアが、円筒状噴出部４５から容器５内の液体に向かって噴出される。続いて、容器５内では、ポンプ部材６の円筒状噴出部４５からのエアの噴出により、その空気圧が液体に付与され、容器５内の所定量の液体が、空気圧により押し出されるようにしてノズル部材７内に浸入する。 Then, in the liquid discharge device 1 according to the present embodiment, when the liquid in the container 5 is discharged to the outside, the user pushes the upper surface of the pump main body 44 of the pump member 6 with a finger. Then, the pump main body 44 contracts along the axial direction, so that the air in the pump main body 44 is ejected from the cylindrical ejection portion 45 toward the liquid in the container 5. Subsequently, in the container 5, the air pressure is applied to the liquid by ejecting air from the cylindrical ejection portion 45 of the pump member 6, and a predetermined amount of the liquid in the container 5 is pushed out by the air pressure so that the nozzle is ejected. It penetrates into the member 7.

続いて、ノズル部材７内の液体は、その先端ノズル部５４から下方に向かって適量吐出される。一方、使用者がポンプ部材６のポンプ本体部４４から指を離すと、ポンプ本体部４４内には、容器５内から円筒状噴出部４５を介して空気が吸引されることで、ポンプ本体４４が復元する。このとき、容器５内が負圧となるために、ノズル部材７内で外部に吐出されなかった微量の液体が、速やかに容器５内に吸引される。 Subsequently, an appropriate amount of the liquid in the nozzle member 7 is discharged downward from the tip nozzle portion 54. On the other hand, when the user releases the finger from the pump main body 44 of the pump member 6, air is sucked into the pump main body 44 from the container 5 through the cylindrical ejection portion 45, so that the pump main body 44 Restores. At this time, since the pressure inside the container 5 becomes negative, a small amount of liquid that has not been discharged to the outside inside the nozzle member 7 is quickly sucked into the container 5.

なお、容器５内の液体を全て使い切った際には、カバー部材９、ポンプ部材６、ノズル部材７及び内蓋部材８を容器５及び外容器４から取り外す。続いて、外容器４内からキャップ部材１６を含む容器５（内部は空）を離脱させる。続いて、内部に液体が貯溜された新品の容器５を外容器４内に配置して、内蓋部材８、ノズル部材７、ポンプ部材６及びカバー部材９を容器５内及び外容器４に組み付ける。 When all the liquid in the container 5 is used up, the cover member 9, the pump member 6, the nozzle member 7, and the inner lid member 8 are removed from the container 5 and the outer container 4. Subsequently, the container 5 (the inside is empty) including the cap member 16 is separated from the inside of the outer container 4. Subsequently, a new container 5 in which the liquid is stored is arranged in the outer container 4, and the inner lid member 8, the nozzle member 7, the pump member 6 and the cover member 9 are assembled into the container 5 and the outer container 4. ..

以上説明したように、本考案の実施形態に係る液吐出装置１は、少なくとも、液体が貯溜される容器５と、該容器５内にエアを噴出するポンプ部材６と、該ポンプ部材６からのエアの噴出により、容器５内から押し出される液体を外部に導くノズル部材７と、を備えている。そして、使用者が容器５内の液体を使用する際には、使用者が指でポンプ部材６のポンプ本体部４４の上面を押し込み、ポンプ部材６からエアを容器５内に噴出させることで、容器５内の液体が空気圧によって押し出され、ノズル部材７内を経由して外部に吐出される。 As described above, the liquid discharge device 1 according to the embodiment of the present invention comprises at least a container 5 for storing liquid, a pump member 6 for ejecting air into the container 5, and the pump member 6. It includes a nozzle member 7 that guides the liquid extruded from the inside of the container 5 to the outside by ejecting air. Then, when the user uses the liquid in the container 5, the user pushes the upper surface of the pump main body 44 of the pump member 6 with a finger and blows air from the pump member 6 into the container 5. The liquid in the container 5 is pushed out by air pressure and discharged to the outside via the inside of the nozzle member 7.

これにより、本考案の実施形態に係る液吐出装置１では、従来（特許文献１に係る押し下げヘッド式のポンプ）のように、吸い込み弁や吐出弁、コイルスプリングを必要とせず部品点数を低減させることができ、その構造を簡素化することができる。また、本考案の実施形態に係る液吐出装置１では、金属部品を採用していないので、廃棄する際の分別等を行う必要もなく、その取り扱いが非常に良好となる。 As a result, the liquid discharge device 1 according to the embodiment of the present invention does not require a suction valve, a discharge valve, or a coil spring as in the conventional case (push-down head type pump according to Patent Document 1), and reduces the number of parts. And its structure can be simplified. Further, since the liquid discharge device 1 according to the embodiment of the present invention does not use metal parts, it is not necessary to perform sorting or the like at the time of disposal, and the handling thereof is very good.

また、本考案の実施形態に係る液吐出装置１では、金属部品を採用していないので、液体として、醤油やお酢、ソース等の調味料にも適用可能となり、採用できる分野が広がる。しかも、本考案の実施形態に係る液吐出装置１では、部品点数が少なく、構造が簡素化されているので、組立作業も容易となり、コスト低減に繋がる。 Further, since the liquid discharge device 1 according to the embodiment of the present invention does not use metal parts, it can be applied as a liquid to seasonings such as soy sauce, vinegar, and sauce, and the fields in which it can be used are expanded. Moreover, in the liquid discharge device 1 according to the embodiment of the present invention, the number of parts is small and the structure is simplified, so that the assembly work is easy and the cost is reduced.

さらに、本考案の実施形態に係る液吐出装置１では、ポンプ部材６は、伸縮することでその内部からエアを吸排可能であって、蛇腹状に形成されるポンプ本体部４４を有するので、容器５内の液体を外部に吐出させる際には、単に、使用者が、ポンプ本体部４４の上面を押す操作を行えばよく、使い勝手が非常に良好となる。 Further, in the liquid discharge device 1 according to the embodiment of the present invention, the pump member 6 can suck and discharge air from the inside by expanding and contracting, and has a pump main body 44 formed in a bellows shape. When the liquid in No. 5 is discharged to the outside, the user simply pushes the upper surface of the pump main body 44, and the usability is very good.

一方、使用者がポンプ部材６のポンプ本体部４４の上面から指を離すと、ポンプ本体部４４内に容器５内から円筒状噴出部４５を介して空気が吸引されることで、ポンプ本体部４４が復元する。ポンプ本体部４４が復元する際、容器５内が負圧となるために、ノズル部材７内で外部に吐出されなかった微量の液体が、速やかに容器５内に吸引される。これにより、ポンプ本体部４４を指で押して液体を使用した後、ノズル部材７の先端ノズル部５４からの液だれを抑制することができる。 On the other hand, when the user releases his finger from the upper surface of the pump main body 44 of the pump member 6, air is sucked into the pump main body 44 from the container 5 through the cylindrical ejection portion 45, so that the pump main body portion 44 is restored. When the pump body 44 is restored, the pressure inside the container 5 becomes negative, so that a small amount of liquid that has not been discharged to the outside inside the nozzle member 7 is quickly sucked into the container 5. As a result, it is possible to suppress dripping from the tip nozzle portion 54 of the nozzle member 7 after pressing the pump main body portion 44 with a finger to use the liquid.

さらに、本考案の実施形態に係る液吐出装置１では、液体が貯溜される容器５は、外容器４内に配置され、容器５と外容器４とが別体に構成されており、容器５は紙製容器にて構成されている。その結果、容器５内の液体を使い切ると、容器５を外容器４内から容易に取り除くことができる。そして、容器５内の液体を使い切った際、液体が貯溜された新品の容器５に容易に取り換えることができる。 Further, in the liquid discharge device 1 according to the embodiment of the present invention, the container 5 in which the liquid is stored is arranged in the outer container 4, and the container 5 and the outer container 4 are configured as separate bodies. Is composed of a paper container. As a result, when the liquid in the container 5 is used up, the container 5 can be easily removed from the outer container 4. Then, when the liquid in the container 5 is used up, it can be easily replaced with a new container 5 in which the liquid is stored.

しかも、カバー部材９、ポンプ部材６、ノズル部材７、内蓋部材８及び外容器４は、容器５内の液体を使い切った後何度でも再使用可能であるので、プラスチック製品（合成樹脂製品）のゴミ増加を抑制でき、ひいては、プラスチック製品による環境汚染を抑制することができる。また、容器５は紙製容器であるので、さらに、プラスチック製品のゴミ増加を抑制することができる。 Moreover, since the cover member 9, the pump member 6, the nozzle member 7, the inner lid member 8 and the outer container 4 can be reused as many times as necessary after the liquid in the container 5 is used up, it is a plastic product (synthetic resin product). It is possible to suppress the increase of garbage, and by extension, the environmental pollution caused by plastic products. Further, since the container 5 is a paper container, it is possible to further suppress the increase of dust in the plastic product.

さらにまた、本考案の実施形態に係る液吐出装置１では、蛇腹状のポンプ本体部４４は、外容器４を上方から覆うカバー部材９に設けた円筒状部４１内に配置され、ポンプ本体部４４が円筒状部４１によりガイドされているので、使用時に、使用者がポンプ本体部４４の上面を押す際にポンプ本体部４４の傾倒を抑制でき、ポンプ本体部４４を軸方向に沿って正常に伸縮させることができる。 Furthermore, in the liquid discharge device 1 according to the embodiment of the present invention, the bellows-shaped pump main body 44 is arranged in the cylindrical portion 41 provided on the cover member 9 that covers the outer container 4 from above, and the pump main body Since the 44 is guided by the cylindrical portion 41, it is possible to suppress the tilt of the pump main body 44 when the user pushes the upper surface of the pump main body 44 during use, and the pump main body 44 is normally aligned along the axial direction. Can be expanded and contracted.

さらにまた、本考案の実施形態に係る液吐出装置１では、ノズル部材７が、縦ノズル部５２と横ノズル部５３との間に屈曲自在な第１蛇腹部５６が設けられ、横ノズル部５３と先端ノズル部５４との間に屈曲自在な第２蛇腹部５７が設けられて構成される。これにより、本液吐出装置１を組み付ける際、容器５のキャップ部材１６のノズル用挿通孔２０が内蓋部材８の半円板状部２４側に位置していないときでも、ノズル部材７の先端ノズル部５４の先端吐出口を、第１及び第２蛇腹部５６、５７により、内蓋部材８のスリット部２８の一端部から下方に突出させることができ、その組み付けが容易となる。 Furthermore, in the liquid discharge device 1 according to the embodiment of the present invention, the nozzle member 7 is provided with a flexible first bellows portion 56 between the vertical nozzle portion 52 and the horizontal nozzle portion 53, and the horizontal nozzle portion 53. A flexible second bellows portion 57 is provided between the tip nozzle portion 54 and the tip nozzle portion 54. As a result, when assembling the liquid discharge device 1, even when the nozzle insertion hole 20 of the cap member 16 of the container 5 is not located on the semicircular plate-shaped portion 24 side of the inner lid member 8, the tip of the nozzle member 7 The tip discharge port of the nozzle portion 54 can be projected downward from one end of the slit portion 28 of the inner lid member 8 by the first and second bellows portions 56 and 57, and the assembly thereof becomes easy.

なお、ポンプ部材６のポンプ本体部４４に、外気を内部に吸引するための吸引孔（図示は省略するが小孔）を設け、使用者が指でポンプ本体部４４の上面を押し込んで軸方向に沿って縮小する際には吸引孔を閉じる一方、使用者の指がポンプ本体部４４の上面から離れた際には、ポンプ本体部４４内への外気の吸入を許容すべく、吸引孔を開放する逆止弁（図示略）を設けてもよい。 The pump body 44 of the pump member 6 is provided with a suction hole (small hole (not shown)) for sucking outside air inside, and the user pushes the upper surface of the pump body 44 with a finger in the axial direction. When the suction hole is closed when the pump body is reduced along, when the user's finger is separated from the upper surface of the pump body 44, the suction hole is opened to allow the outside air to be sucked into the pump body 44. A check valve (not shown) that opens may be provided.
