Description

本発明は吐出器に関するものである。 The present invention relates to a dispenser.

この種の吐出器として、従来から、容器体の口部に上方付勢状態で立設されるステムと、第１天壁部、第１天壁部から下方に向けて延設されて内部に前記ステムが嵌合された嵌合筒部、および第１天壁部から下方に向けて延設されて嵌合筒部をその径方向外方から囲繞する囲繞筒部を備えるとともに、ノズル孔が形成された押下ヘッドと、ステムが上下動自在に挿入された挿通孔を有する第２天壁部、および第２天壁部の外周縁から下方に向けて延設された装着周壁部を備え、容器体の口部に装着される装着キャップと、が備えられ、前記押下ヘッドをステムとともに押し下げることにより、容器体内の液体を前記ステムの内部を通してノズル孔から吐出する構成が知られている。
この吐出器においては一般に、その使用に際し、一方の手のひらをノズル孔の開口部にその下側から添えつつ、他方の手で押下ヘッドを押し下げて、一方の手のひらでノズル孔から吐出された容器体内の液体を受けているが、近年では、片手だけを用いて押下ヘッドを押し下げかつノズル孔から吐出された液体を受けられる構成が提案されている。
この構成として、例えば下記特許文献１に示されるような、装着キャップの装着周壁部に径方向外方に向けて支持板を突設した構成が知られている。
特開２００３−１６５５９１号公報特許第３６４７５７４号公報 Conventionally, as this type of discharger, a stem that is erected in an upwardly biased state at the mouth of the container body, a first ceiling wall, and a first ceiling wall that extends downward from the inside. A fitting cylinder part fitted with the stem, and a surrounding cylinder part extending downward from the first top wall part and surrounding the fitting cylinder part from the outside in the radial direction; A formed pressing head, a second top wall portion having an insertion hole into which the stem is inserted so as to be movable up and down, and a mounting peripheral wall portion extending downward from the outer peripheral edge of the second top wall portion, There is known a configuration in which a mounting cap mounted on the mouth portion of the container body is provided, and the liquid in the container body is discharged from the nozzle hole through the inside of the stem by pushing down the pressing head together with the stem.
In general, in this discharge device, one palm is attached to the opening of the nozzle hole from the lower side while the pressing head is pushed down with the other hand, and the inside of the container discharged from the nozzle hole with one palm is used. In recent years, a configuration has been proposed in which the pressing head is pushed down using only one hand and the liquid discharged from the nozzle holes can be received.
As this configuration, for example, a configuration in which a support plate protrudes radially outward from a mounting peripheral wall portion of a mounting cap as shown in Patent Document 1 is known.
JP 20031655591 A Japanese Patent No. 3647574

しかしながら、前記従来の吐出器では、装着キャップの装着周壁部に支持板を突設していたので、支持板の出っ張り量が大きくなり、例えば搬送時に支持板同士が引っ掛かったり、あるいは店頭での陳列時に占有スペースが嵩張ったりする等、取り扱い性が低下するおそれがあった。さらにこのように支持板の出っ張り量が大きくなると、この吐出器の装着された容器が把持し難くなるので、装着キャップの外径を小さくして、この容器の把持のし易さを確保しなければならなくなり、例えば吐出容量等といった吐出器の性能上、さらにはデザイン上の制約が生ずるおそれもあった。
ここで、従来から、需要者が容器体内の液体を使用する前の段階で、例えば押下ヘッドが不用意に押し下げられる等して液体が吐出されるのを防止するために、例えば上記特許文献２に示されるような、押下ヘッドにおける囲繞筒部の下端縁と装着キャップとの間に、ストッパ筒部を離脱可能に介装する構成が提案されているが、この場合、ストッパ筒部が設けられた分、吐出器全体の上下方向における長さが大きくなるという問題があった。 However, in the conventional dispenser, since the support plate protrudes from the mounting peripheral wall portion of the mounting cap, the protruding amount of the support plate becomes large. For example, the support plates may be caught during transportation or displayed at the storefront. At times, the occupied space may be bulky, and the handleability may be reduced. Further, when the protruding amount of the support plate is increased in this manner, it becomes difficult to grip the container to which the discharge device is mounted. Therefore, the outer diameter of the mounting cap must be reduced to ensure the ease of gripping the container. For example, there is a possibility that restrictions on the performance of the ejector, such as a discharge capacity, and design restrictions may occur.
Here, in order to prevent the liquid from being discharged by, for example, the pressing head being inadvertently pressed down before the consumer uses the liquid in the container, for example, the above-mentioned Patent Document 2 In this case, the stopper cylinder part is provided between the lower end edge of the surrounding cylinder part in the pressing head and the mounting cap so as to be detachable. Accordingly, there is a problem that the length of the entire discharger in the vertical direction increases.

本発明は、このような事情を考慮してなされたもので、支持板の出っ張り量を抑えつつ、片手だけを用いて押下ヘッドを押し下げかつノズル孔から吐出された液体を受けることができるとともに、吐出器の上下方向における長さが大きくなるのを抑制しつつ、需要者が容器体内の液体を使用する前の段階で、例えば押下ヘッドが不用意に押し下げられる等して液体が吐出されるのを防止することができる吐出器を提供することを目的とする。 The present invention has been made in consideration of such circumstances, and while suppressing the amount of protrusion of the support plate, it is possible to receive the liquid discharged from the nozzle hole by pressing down the pressing head using only one hand, In the stage before the consumer uses the liquid in the container, the liquid is discharged by, for example, the pressing head being inadvertently pressed down while suppressing the increase in the vertical length of the discharger. It is an object of the present invention to provide a discharger that can prevent the above-described problem.

上記課題を解決して、このような目的を達成するために、本発明の吐出器は、容器体の口部に上方付勢状態で立設されるステムと、第１天壁部、第１天壁部から下方に向けて延設されて内部に前記ステムが嵌合された嵌合筒部、および第１天壁部から下方に向けて延設されて嵌合筒部をその径方向外方から囲繞する囲繞筒部を備えるとともに、ノズル孔が形成された押下ヘッドと、前記ステムが上下動自在に挿入された挿通孔を有する第２天壁部、および第２天壁部の外周縁から下方に向けて延設された装着周壁部を備え、容器体の口部に装着される装着キャップと、が備えられ、前記押下ヘッドをステムとともに押し下げることにより、容器体内の液体を前記ステムの内部を通してノズル孔から吐出する構成とされた吐出器であって、前記装着キャップの第２天壁部に、前記挿通孔および前記囲繞筒部よりも大径でかつ装着周壁部よりも小径の被挟持筒部が上方に向けて延設されるとともに、この被挟持筒部の上端に、径方向外方に向けて支持板が突設され、前記押下ヘッドおよびステムがその上昇端位置に位置した状態で、前記囲繞筒部の下端縁は支持板よりも上方に位置するとともに、この支持板の上面に板状のストッパが離脱可能に配置され、このストッパの上面に前記囲繞筒部の下端縁が当接若しくは上下方向で対向していることを特徴とする。
この発明では、装着キャップの第２天壁部に被挟持筒部が立設されるとともに、この被挟持筒部の上端に径方向外方に向けて支持板が突設されているので、例えば一方の手のひらをノズル孔の開口部にその下側から添えつつ、その手の中指と人指し指、または薬指と中指等で被挟持筒部をその径方向に挟み込んだ状態で、この手を上昇させると、前記中指と人指し指、または薬指と中指等により支持板がその下面側から支持されることによって、当該吐出器の装着された容器体が持ち上げられることになる。さらにこの状態で、前記一方の手の親指で押下ヘッドを押し下げることにより、ノズル孔から吐出された容器体内の液体が前記一方の手のひらで受け止められる。
以上より、片手だけを用いて押下ヘッドを押し下げかつノズル孔から吐出された液体を受けることができる。
さらに、被挟持筒部が装着周壁部よりも小径に形成され、この被挟持筒部の上端に支持板が設けられているので、支持板が装着周壁部よりも径方向外側に大きく出っ張るのを抑えることが可能になり、前述の作用効果を奏する吐出器の取り扱い性が低下するのを防ぐことができる。
さらにまた、被挟持筒部が装着周壁部よりも小径に形成されていることから、需要者の手の大小を問わず、前述のようにして中指と人指し指、または薬指と中指等で被挟持筒部をその径方向に強固かつ確実に挟み込むことが可能になる。
また、押下ヘッドおよびステムがその上昇端位置に位置した状態で、囲繞筒部の下端縁が支持板よりも上方に位置するとともに、支持板の上面にストッパが離脱可能に配置され、このストッパの上面に前記囲繞筒部の下端縁が当接若しくは上下方向で対向しているので、需要者が容器体内の液体を使用する前の段階で、押下ヘッドに下方に向けた外力が作用しても、この押下ヘッドにおける囲繞筒部の下端縁をストッパの上面に当接させることが可能になり、この押下ヘッドが不用意に押し下げられ液体が吐出されるのを防ぐことができる。
しかも、前記ストッパが板状に形成されているので、このストッパを設けたことにより吐出器全体の上下方向における長さが大きくなるのを抑制することができる。 In order to solve the above-described problems and achieve such an object, a discharger according to the present invention includes a stem erected in an upward biased state at a mouth portion of a container body, a first ceiling wall portion, a first ceiling portion, A fitting cylinder portion extending downward from the top wall portion and having the stem fitted therein, and a fitting cylinder portion extending downward from the first ceiling wall portion and extending radially outward And a second head wall portion including a pressing head in which a nozzle hole is formed, an insertion hole into which the stem is vertically movable, and an outer peripheral edge of the second ceiling wall portion. And a mounting cap that is mounted on the mouth of the container body, and by pushing down the pressing head together with the stem, the liquid in the container body A discharge device configured to discharge from the nozzle hole through the inside, A sandwiched cylinder portion having a diameter larger than that of the insertion hole and the surrounding tube portion and smaller than that of the mounting peripheral wall portion is extended upward on the second top wall portion of the wearing cap. A support plate protrudes radially outward from the upper end of the portion, and the lower end edge of the surrounding tube portion is positioned above the support plate in a state where the pressing head and the stem are positioned at the raised end position. In addition, a plate-like stopper is detachably disposed on the upper surface of the support plate, and the lower end edge of the surrounding tube portion is in contact with or vertically opposed to the upper surface of the stopper.
In the present invention, the sandwiched cylinder portion is erected on the second top wall portion of the mounting cap, and the support plate protrudes radially outward from the upper end of the sandwiched cylinder portion. While attaching the palm of one hand to the opening of the nozzle hole from the lower side and raising the hand while holding the clamped cylinder part in the radial direction with the middle finger and index finger or the ring finger and middle finger of the hand, etc. When the support plate is supported from the lower surface side by the middle finger and the index finger or the ring finger and the middle finger, the container body to which the discharge device is attached is lifted. Further, in this state, the liquid in the container discharged from the nozzle hole is received by the palm of the one hand by depressing the pressing head with the thumb of the one hand.
As described above, the liquid ejected from the nozzle hole can be received while the pressing head is depressed using only one hand.
Further, the sandwiched cylinder portion is formed with a smaller diameter than the mounting peripheral wall portion, and a support plate is provided at the upper end of the sandwiched cylindrical portion, so that the support plate protrudes more radially outward than the mounting peripheral wall portion. Thus, it is possible to prevent the handling property of the discharger having the above-described effects from being deteriorated.
Furthermore, since the clamped cylinder part is formed with a smaller diameter than the mounting peripheral wall part, the clamped cylinder can be clamped with the middle finger and the index finger or the ring finger and the middle finger as described above regardless of the size of the consumer's hand. The portion can be firmly and securely sandwiched in the radial direction.
In addition, the lower end edge of the surrounding cylinder portion is positioned above the support plate in a state where the pressing head and the stem are positioned at the rising end position, and a stopper is detachably disposed on the upper surface of the support plate. Since the lower end edge of the surrounding cylinder portion is in contact with the upper surface or opposed in the vertical direction, even if an external force directed downward is applied to the pressing head before the consumer uses the liquid in the container body The lower end edge of the surrounding cylinder portion of the pressing head can be brought into contact with the upper surface of the stopper, and the pressing head can be prevented from being carelessly pressed and liquid discharged.
And since the said stopper is formed in plate shape, it can suppress that the length in the up-down direction of the whole discharger is provided by providing this stopper.

ここで、前記第２天壁部において挿通孔の外周縁部には上方に向けてガイド筒部が延設されるとともに、このガイド筒部の上部は支持板の上面から上方に突出し、前記ストッパには嵌合孔が形成され、前記押下ヘッドおよびステムがその上昇端位置に位置した状態で、前記ガイド筒部の上端部における外側と、前記囲繞筒部の下端部における内側とが近接若しくは当接するとともに、前記嵌合孔に、前記ガイド筒部の上部において前記囲繞筒部の下端部における内側と近接若しくは当接した上端部よりも下方に位置する部分の外周面が離脱可能に嵌合されてもよい。
この場合、ガイド筒部の上端部における外側と、囲繞筒部の下端部における内側とが近接若しくは当接しているので、押下ヘッドおよびステムがその上昇端位置に位置した状態で、ガイド筒部と囲繞筒部との間を通して外部から例えば水等が侵入するのを抑制することが可能になる。
また、ストッパの嵌合孔に、ガイド筒部の上部において囲繞筒部の下端部における内側と近接若しくは当接した上端部よりも下方に位置する部分の外周面が離脱可能に嵌合されているので、このストッパを支持板の上面にぐらつかせることなく安定して配置することが可能になり、需要者が容器体内の液体を使用する前の段階で、不用意にストッパが吐出器から外れるのを防ぐことができる。 Here, a guide tube portion extends upward from the outer peripheral edge of the insertion hole in the second top wall portion, and the upper portion of the guide tube portion protrudes upward from the upper surface of the support plate, and the stopper Is formed with a fitting hole so that the outer side at the upper end of the guide cylinder and the inner side at the lower end of the surrounding cylinder are close to each other or in a state where the pressing head and the stem are positioned at the raised end position. In addition, the outer peripheral surface of the portion located below the upper end portion close to or in contact with the inner side of the lower end portion of the surrounding tube portion at the upper portion of the guide tube portion is detachably fitted into the fitting hole. May be.
In this case, the outer side at the upper end portion of the guide tube portion and the inner side at the lower end portion of the surrounding tube portion are close to or in contact with each other. For example, water can be prevented from entering from the outside through the space between the surrounding cylinder portions.
In addition, the outer peripheral surface of the portion located below the upper end portion close to or in contact with the inner side of the lower end portion of the surrounding tube portion at the upper portion of the guide tube portion is detachably fitted into the fitting hole of the stopper. Therefore, this stopper can be stably arranged without swaying the upper surface of the support plate, and the stopper is inadvertently detached from the dispenser before the user uses the liquid in the container. Can be prevented.

また、前記ストッパには、前記嵌合孔から径方向外方に向けて延在し当該ストッパの外周縁に開口する通過孔が形成されるとともに、このストッパの外周縁において前記通過孔が開口した部分の、当該ストッパの径方向で前記嵌合孔を挟んだ反対側には、当該ストッパの周方向に沿って延びる補強周壁が連結されてもよい。
この場合、板状に形成されたストッパに嵌合孔および通過孔が形成されているので、このストッパをガイド筒部に対して容易に着脱することができる。
また、ストッパの外周縁において通過孔が開口した部分の、当該ストッパの径方向で嵌合孔を挟んだ反対側に、当該ストッパの周方向に沿って延びる補強周壁が連結されているので、この補強周壁をつまんでストッパをガイド筒部の外周面に対して進退移動させることによって、当該ストッパの着脱を容易に行うことが可能になる。
以上より、操作性の優れたストッパが得られる。 The stopper is formed with a passage hole extending radially outward from the fitting hole and opening at the outer peripheral edge of the stopper, and the passage hole is opened at the outer peripheral edge of the stopper. A reinforcing peripheral wall extending along the circumferential direction of the stopper may be coupled to the opposite side of the portion across the fitting hole in the radial direction of the stopper.
In this case, since the fitting hole and the passage hole are formed in the plate-shaped stopper, the stopper can be easily attached to and detached from the guide tube portion.
In addition, a reinforcing peripheral wall extending along the circumferential direction of the stopper is connected to the opposite side of the stopper where the through hole is opened in the outer peripheral edge of the stopper, with the fitting hole interposed therebetween in the radial direction of the stopper. By holding the reinforcing peripheral wall and moving the stopper forward and backward with respect to the outer peripheral surface of the guide tube portion, the stopper can be easily attached and detached.
From the above, a stopper with excellent operability can be obtained.

さらに、前記第２天壁部、装着周壁部、被挟持筒部および支持板は一体に形成されるとともに、前記被挟持筒部において第２天壁部に連なる下端部に貫通孔が形成されてもよい。
この場合、第２天壁部、装着周壁部、被挟持筒部および支持板が一体に形成されているので、この吐出器が高コストになるのを抑えることができる。
さらに、被挟持筒部において第２天壁部に連なる下端部に貫通孔が形成されているので、被挟持筒部に支持板を設けたことにより、この支持板の上面を介して、装着キャップにおいて被挟持筒部よりも内側の空間内に例えば水等が侵入し易くなったとしても、この侵入物を前記貫通孔を通して外部に排出し易くすることが可能になる。また、このように貫通孔が形成されていることから装着キャップを形成する材料の使用量を低減することも可能になる。 Furthermore, the second top wall portion, the mounting peripheral wall portion, the sandwiched cylinder portion, and the support plate are integrally formed, and a through hole is formed in a lower end portion that is continuous with the second ceiling wall portion in the sandwiched cylinder portion. Also good.
In this case, since the second top wall portion, the mounting peripheral wall portion, the sandwiched cylinder portion, and the support plate are integrally formed, it is possible to suppress the cost of the discharger.
Further, since the through hole is formed in the lower end portion connected to the second ceiling wall portion in the sandwiched cylinder portion, the mounting cap is provided via the upper surface of the support plate by providing the support plate in the sandwiched cylinder portion. In this case, even if water or the like easily enters the space inside the sandwiched cylinder portion, it is possible to easily discharge the intruder to the outside through the through hole. Further, since the through holes are formed in this way, it is possible to reduce the amount of material used to form the mounting cap.

なお、この構成において、前記貫通孔は、被挟持筒部の下端部にその周方向に間隔をあけて複数形成されるとともに、前記第２天壁部の上面は、その径方向中央部側から外側に向かうに従い漸次下方に向けて傾斜してもよい。
この場合、貫通孔が被挟持筒部の下端部にその周方向に間隔をあけて複数形成されるとともに、第２天壁部の上面が、その径方向中央部側から外側に向かうに従い漸次下方に向けて傾斜しているので、前述の侵入物を確実に前記空間内から外部に排出し易くすることができる。 In this configuration, a plurality of the through holes are formed at the lower end portion of the sandwiched cylinder portion with a space in the circumferential direction, and the upper surface of the second top wall portion is from the radial center portion side. You may incline gradually toward the downward direction as it goes outside.
In this case, a plurality of through-holes are formed at the lower end portion of the sandwiched cylindrical portion with a space in the circumferential direction, and the upper surface of the second ceiling wall portion gradually lowers as it goes outward from the radial center portion side. Therefore, the intruder can be easily discharged from the space to the outside.

さらに、第２天壁部、装着周壁部、被挟持筒部および支持板さらには前記ガイド筒部が一体に形成された構成においては、ガイド筒部の上端部外周面にリング部材を嵌合し、このリング部材を、囲繞筒部の下端部における内側に近接若しくは当接させるようにしてもよい。
この場合、第２天壁部、装着周壁部、被挟持筒部、支持板および前記ガイド筒部が一体に形成されるとともに、リング部材がガイド筒部の上端部外周面に嵌合されてガイド筒部と一体に形成されていないので、装着キャップを金型内に樹脂を供給して成形する場合に、この金型の構造が複雑になるのを防ぐことができる。 Further, in the configuration in which the second top wall portion, the mounting peripheral wall portion, the clamped cylinder portion, the support plate, and the guide cylinder portion are integrally formed, a ring member is fitted to the outer peripheral surface of the upper end portion of the guide cylinder portion. The ring member may be brought close to or in contact with the inner side of the lower end portion of the surrounding tube portion.
In this case, the second top wall portion, the mounting peripheral wall portion, the sandwiched cylinder portion, the support plate, and the guide cylinder portion are integrally formed, and the ring member is fitted to the outer peripheral surface of the upper end portion of the guide cylinder portion to guide it. Since it is not formed integrally with the cylindrical portion, it is possible to prevent the structure of the mold from becoming complicated when the mounting cap is molded by supplying resin into the mold.

また、前記押下ヘッドおよびステムに連係した液用ピストンが内部を上下方向に摺動する液用シリンダと、前記押下ヘッドに連係した空気用ピストンが内部を上下方向に摺動するとともに、前記装着キャップの内側に取り付けられた空気用シリンダと、前記液用シリンダからの液体と空気用シリンダからの空気とが合流する気液混合室と、前記ノズル孔と気液混合室との間に設置された発泡部材と、を備え、容器体の口部に装着した状態で前記押下ヘッドを押し下げて液用シリンダ内の液体および空気用シリンダ内の空気を加圧することにより、これらの液体および空気を、気液混合室に移送して合流させ発泡部材を通して発泡させて前記ノズル孔から吐出する構成とされてもよい。
この場合、液用ピストンおよび液用シリンダのみならず空気用ピストンおよび空気用シリンダをも備えているので、装着キャップの装着周壁部を大径にしなければならないため、前述の作用効果のうち、支持板の出っ張り量を抑える効果、および需要者の手の大小を問わず中指と人指し指、または薬指と中指等で被挟持筒部をその径方向に強固かつ確実に挟み込ませる効果が顕著に奏功されることになる。 In addition, a liquid cylinder in which a liquid piston linked to the pressing head and the stem slides in an up-and-down direction; an air piston linked to the pressing head slides in an up-and-down direction; and the mounting cap Installed between the nozzle hole and the gas-liquid mixing chamber, the air cylinder attached to the inside, the gas-liquid mixing chamber where the liquid from the liquid cylinder and the air from the air cylinder merge A foaming member, and pressurizing the liquid in the liquid cylinder and the air in the air cylinder by depressing the pressing head in a state of being attached to the mouth of the container body, thereby removing the liquid and the air. It may be configured to be transferred to the liquid mixing chamber, merged, foamed through the foaming member and discharged from the nozzle hole.
In this case, since not only the liquid piston and the liquid cylinder but also the air piston and the air cylinder are provided, the mounting peripheral wall portion of the mounting cap must have a large diameter. The effect of suppressing the protruding amount of the board and the effect of firmly and reliably sandwiching the clamped cylinder portion in the radial direction between the middle finger and the index finger or the ring finger and the middle finger regardless of the size of the consumer's hand are remarkably successful. It will be.

この発明に係る吐出器によれば、支持板の出っ張り量を抑えつつ、片手だけを用いて押下ヘッドを押し下げかつノズル孔から吐出された液体を受けることができるとともに、吐出器の上下方向における長さが大きくなるのを抑制しつつ、需要者が容器体内の液体を使用する前の段階で、例えば押下ヘッドが不用意に押し下げられる等して液体が吐出されるのを防止することができる。 According to the ejector according to the present invention, while suppressing the protruding amount of the support plate, it is possible to receive the liquid ejected from the nozzle hole by pushing down the pressing head using only one hand, and the length of the ejector in the vertical direction. It is possible to prevent the liquid from being discharged by, for example, the pressing head being inadvertently pushed down at a stage before the consumer uses the liquid in the container, while suppressing the increase in size.

以下、図面を参照し、この発明の実施の形態について説明する。この実施形態に係る吐出器１０には、図示されない容器体の口部に上方付勢状態で立設されるステム１１と、第１天壁部１３、第１天壁部１３から下方に向けて延設されて内部にステム１１が嵌合された嵌合筒部１４、および第１天壁部１３から下方に向けて延設されて嵌合筒部１４をその径方向外方から囲繞する囲繞筒部２７を備えるとともに、ノズル孔１２が形成された押下ヘッド１５と、ステム１１が上下動自在に挿入された挿通孔１９ａを有する第２天壁部１７、および第２天壁部１７の外周縁から下方に向けて延設された装着周壁部１８を備え、容器体の口部に装着される装着キャップ２０と、が備えられている。 Embodiments of the present invention will be described below with reference to the drawings.

以上より、片手だけを用いて押下ヘッドを押し下げかつノズル孔から吐出された液体を受けることができる。 As described above, according to the dispenser 10 according to the present embodiment, the sandwiched cylinder portion 30 is erected on the second top wall portion 17 of the mounting cap 20, and the diameter is formed at the upper end of the sandwiched cylinder portion 30. Since the support plate 31 protrudes outward in the direction, for example, the palm of one hand is attached to the opening of the nozzle hole 12 from the lower side, and is covered with the middle finger and the index finger or the ring finger and the middle finger of the hand. When this hand is raised in a state where the sandwiching cylinder portion 30 is sandwiched in the radial direction, the support plate 31 is supported from the lower surface side by the middle finger and the index finger, or the ring finger and the middle finger, etc. It becomes possible to lift the container body to which is attached. Further, in this state, the liquid in the container discharged from the nozzle hole can be received by the palm of the one hand by pushing down the pressing head with the thumb of the one hand.

さらに、被挟持筒部３０が装着周壁部１８よりも小径に形成され、この被挟持筒部３０の上端に支持板３１が設けられているので、支持板３１が装着周壁部１８よりも径方向外側に大きく出っ張るのを抑えることが可能になり、前述の作用効果を奏する吐出器１０の取り扱い性が低下するのを防ぐことができる。
さらにまた、被挟持筒部３０が装着周壁部１８よりも小径に形成されていることから、需要者の手の大小を問わず、前述のようにして中指と人指し指、または薬指と中指等で被挟持筒部３０をその径方向に強固かつ確実に挟み込むことが可能になる。 Further, the sandwiched cylinder portion 30 is formed to have a smaller diameter than the mounting peripheral wall portion 18, and the support plate 31 is provided at the upper end of the sandwiched cylinder portion 30, so that the support plate 31 is more radial than the mounting peripheral wall portion 18. It is possible to suppress the protrusion to the outside greatly, and it is possible to prevent the handleability of the ejector 10 having the above-described effects from being deteriorated.
Furthermore, since the sandwiched cylinder part 30 is formed to have a smaller diameter than the mounting peripheral wall part 18, the middle finger and the index finger or the ring finger and the middle finger or the like can be covered as described above regardless of the size of the consumer's hand. It becomes possible to pinch the clamping cylinder part 30 firmly and reliably in the radial direction.

また、押下ヘッド１５およびステム１１がその上昇端位置に位置した状態で、囲繞筒部２７の下端縁が支持板３１よりも上方に位置するとともに、支持板３１の上面にストッパ３３が離脱可能に配置され、このストッパ３３の上面に囲繞筒部２７の下端縁が当接しているので、需要者が容器体内の液体を使用する前の段階で、押下ヘッド１５に下方に向けた外力が作用しても、この押下ヘッド１５における囲繞筒部２７の下端縁をストッパ３３の上面に当接させることが可能になり、この押下ヘッド１５が不用意に押し下げられ液体が吐出されるのを防ぐことができる。
しかも、ストッパ３３が板状に形成されているので、このストッパ３３を設けたことにより吐出器１０全体の上下方向における長さが大きくなるのを抑制することができる。 In addition, the lower end edge of the surrounding tube portion 27 is positioned above the support plate 31 with the pressing head 15 and the stem 11 positioned at the rising end position, and the stopper 33 can be detached from the upper surface of the support plate 31. Since the lower end edge of the surrounding cylinder portion 27 is in contact with the upper surface of the stopper 33, an external force directed downward is applied to the pressing head 15 before the consumer uses the liquid in the container. However, the lower end edge of the surrounding cylinder portion 27 of the pressing head 15 can be brought into contact with the upper surface of the stopper 33, and the pressing head 15 can be prevented from being carelessly pressed and discharged. it can.
In addition, since the stopper 33 is formed in a plate shape, the provision of the stopper 33 can suppress an increase in the length of the entire discharger 10 in the vertical direction.

さらに、本実施形態では、押下ヘッド１５およびステム１１がその上昇端位置に位置した状態で、ガイド筒部１９の上端部外周面に設けられたリング部材３５が、囲繞筒部２７の下端部内周面に設けられた筒部材３２に近接若しくは当接しているので、ガイド筒部１９と囲繞筒部２７との間を通して外部から例えば水等が侵入するのを抑制することが可能になる。ここで、例えばリング部材３５および筒部材３２のうちの少なくとも一方をゴム状弾性体で形成し、他方に当接させると、この効果が確実に奏功されることになる。
また、ストッパ３３の嵌合孔３３ａに、ガイド筒部１９の上部において囲繞筒部２７の下端部内周面に設けられた筒部材３２と近接若しくは当接した上端部よりも下方に位置する部分の外周面が離脱可能に嵌合されているので、このストッパ３３を支持板３１の上面にぐらつかせることなく安定して配置することが可能になり、需要者が容器体内の液体を使用する前の段階で、不用意にストッパ３３が吐出器１０から外れるのを防ぐことができる。 Further, in the present embodiment, the ring member 35 provided on the outer peripheral surface of the upper end portion of the guide tube portion 19 is in the inner periphery of the lower end portion of the surrounding tube portion 27 in a state where the pressing head 15 and the stem 11 are positioned at the rising end position. Since it is close to or in contact with the cylindrical member 32 provided on the surface, it is possible to suppress, for example, water or the like from entering from the outside through between the guide cylindrical portion 19 and the surrounding cylindrical portion 27. Here, for example, when at least one of the ring member 35 and the cylindrical member 32 is formed of a rubber-like elastic body and brought into contact with the other, this effect is reliably achieved.
Further, in the fitting hole 33 a of the stopper 33, a portion located below the upper end portion in proximity to or in contact with the cylindrical member 32 provided on the inner peripheral surface of the lower end portion of the surrounding tube portion 27 in the upper portion of the guide tube portion 19. Since the outer peripheral surface is detachably fitted, the stopper 33 can be stably disposed without swaying the upper surface of the support plate 31 before the user uses the liquid in the container. It is possible to prevent the stopper 33 from being inadvertently detached from the discharge device 10 at a stage.

また、板状に形成されたストッパ３３に嵌合孔３３ａおよび通過孔３３ｂが形成されているので、このストッパ３３をガイド筒部１９に対して容易に着脱することができる。さらに本実施形態では、ストッパ３３に補助孔３３ｃが形成されているので、ストッパ３３のガイド筒部１９への着脱をより一層容易に行うことができる。さらにまた、ストッパ３３に複数の貫通孔３３ｅが形成されているので、このストッパ３３を形成するのに用いる材料の量を低減することも可能になる。
さらに、ストッパ３３の外周縁において補助孔３３ｃの終端３３ｄと対応する位置に、当該ストッパ３３の周方向に沿って延びる補強周壁３３ｆが連結されているので、この補強周壁３３ｆをつまんでストッパ３３をガイド筒部１９の外周面に対して進退移動させることによって、当該ストッパ３３の着脱を容易に行うことが可能になる。
以上より、操作性の優れたストッパ３３が得られる。 Further, since the fitting hole 33 a and the passage hole 33 b are formed in the stopper 33 formed in a plate shape, the stopper 33 can be easily attached to and detached from the guide tube portion 19. Furthermore, in this embodiment, since the auxiliary hole 33c is formed in the stopper 33, the stopper 33 can be attached to and detached from the guide tube portion 19 more easily. Furthermore, since the plurality of through holes 33e are formed in the stopper 33, the amount of material used to form the stopper 33 can be reduced.
Further, since a reinforcing peripheral wall 33f extending along the circumferential direction of the stopper 33 is connected to a position corresponding to the end 33d of the auxiliary hole 33c on the outer peripheral edge of the stopper 33, the stopper 33 is held by pinching the reinforcing peripheral wall 33f. The stopper 33 can be easily attached and detached by moving it forward and backward with respect to the outer peripheral surface of the guide tube portion 19.
From the above, the stopper 33 with excellent operability can be obtained.

また、本実施形態では、第２天壁部１７、装着周壁部１８、ガイド筒部１９、被挟持筒部３０および支持板３１が一体に形成されているので、この吐出器１０が高コストになるのを抑えることができる。
さらに、被挟持筒部３０において第２天壁部１７に連なる下端部に貫通孔３４が形成されているので、被挟持筒部３０に支持板３１を設けたことにより、この支持板３１の上面を介して、装着キャップ２０において第２天壁部１７、ガイド筒部１９および被挟持筒部３０で画成された空間内に例えば水等が侵入し易くなったとしても、この侵入物を貫通孔３４を通して外部に排出し易くすることが可能になる。また、このように貫通孔３４が形成されていることから装着キャップ２０を形成する材料の使用量を低減することも可能になる。 Moreover, in this embodiment, since the 2nd ceiling wall part 17, the mounting surrounding wall part 18, the guide cylinder part 19, the to-be-clamped cylinder part 30, and the support plate 31 are integrally formed, this discharger 10 becomes high-cost. Can be suppressed.
Furthermore, since the through-hole 34 is formed in the lower end part connected to the 2nd ceiling wall part 17 in the to-be-clamped cylinder part 30, when the support plate 31 was provided in the to-be-clamped cylinder part 30, the upper surface of this support plate 31 Even if water or the like easily enters the space defined by the second ceiling wall portion 17, the guide cylinder portion 19, and the sandwiched cylinder portion 30 in the mounting cap 20, the penetration object penetrates through It becomes possible to facilitate the discharge through the hole 34 to the outside. Further, since the through hole 34 is formed in this way, it is possible to reduce the amount of material used to form the mounting cap 20.

また、本実施形態では、この貫通孔３４が被挟持筒部３０の下端部にその周方向に間隔をあけて複数形成されるとともに、第２天壁部１７の上面が、その径方向中央部側から外側に向かうに従い漸次下方に向けて傾斜しているので、前述の侵入物を確実に前記空間内から外部に排出し易くすることができる。
さらに、前述のように第２天壁部１７、装着周壁部１８、ガイド筒部１９、被挟持筒部３０および支持板３１が一体に形成されるとともに、リング部材３５がガイド筒部１９の上端部外周面に嵌合されてガイド筒部１９と一体に形成されていないので、装着キャップ２０を金型内に樹脂を供給して成形する場合に、この金型の構造が複雑になるのを防ぐことができる。 Further, in the present embodiment, a plurality of the through holes 34 are formed at the lower end portion of the sandwiched cylindrical portion 30 at intervals in the circumferential direction, and the upper surface of the second top wall portion 17 is the central portion in the radial direction.
