Description

本考案は、容器に収容された薬品、化粧品、殺虫剤、塗料などの液体を、エアゾールあるいはトリガーレバーその他の操作で、噴射あるいは泡射させる形式の噴出装置に関する。The present invention relates to an ejection device that ejects or foams liquids such as chemicals, cosmetics, insecticides, and paints contained in a container by aerosol, trigger lever, or other operations.

而してこのエアゾールあるいはトリガー形式などの噴出装置は、そのエアゾールの力あるいはトリガーレバー動作によって、噴出口に連なる液体容器内の内容物を外部空間に噴出させるようになっているが、その使用時にあって直立状態から倒立状態（所謂さかさまの状態および横倒し状態を含む）での使用となった時、容器内の液体が容器の上部に溜まることになるため、液体を噴出装置内のポンプ機構方向に導くことができず噴射させるこが困難であった。Thus, this aerosol or trigger type ejection device is designed to eject the contents in the liquid container connected to the ejection port to the external space by the force of the aerosol or the trigger lever operation. Since the liquid in the container accumulates in the upper part of the container when it is used from the upright state to the inverted state (including the so-called upside down state and sideways state), the pump mechanism in the ejection device It was difficult to inject because it could not be guided in the direction.

そこで横倒の状態になった時、または所謂さかさまの状態になった時でも、容器内の液体が通常の状態と同様に噴出できるようになした特許文献１の先行技術がある。しかしこの発明は所謂エアゾール形式の、液体の計量を分配する分野のポンプであり、液体の分量を制限することで容器中に減圧を発生させることを特徴としており、一般的な噴出器への適用には不向きである。Therefore, there is a prior art of Patent Document 1 in which the liquid in the container can be ejected in the same manner as in a normal state even when it is in a sideways state or a so-called upside down state. However, the present invention is a so-called aerosol type pump in the field of dispensing liquid, and is characterized by generating a reduced pressure in the container by limiting the amount of liquid, and is applied to a general jet Not suitable for.

考案が解決しようとしている課題The problem the device is trying to solve

本考案はエアゾールあるいはトリガーレバー形式などでポンプを作動させる機構の噴出装置にあって、直立状態での使用は勿論倒立の状態（所謂さかさまの状態、ほぼ横倒し状態を含む）で使用しても容器内の液体を噴出（射出、噴霧などを含む）できるようになし、かつ容器内の液体が外部に漏れ出すような虞もなく、安心、安全に使用可能な噴出器を提供することにある。The present invention is an ejection device having a mechanism for operating a pump in the form of an aerosol or a trigger lever, etc., and can be used in an upright state (including a so-called upside down state, substantially lying sideways). It is intended to provide an ejector that can be used safely and safely without causing the liquid in the container to be ejected (including injection, spraying, etc.) and without causing the liquid in the container to leak outside. .

課題を解決するための手段Means for solving the problem

而して本案直立および倒立状態でも使用可能な噴出器装置の特徴は、上部に略水平に設けられ液体を噴出する噴出筒と、その先端部に嵌合させたノズル体と、噴出筒の後端部から垂直に垂下させたポンプ機構と、噴出器本体に設けられ上記ポンプ機構を作動させる部材と、上端が上記ポンプ機構に取り付けられ、末端を上記容器の下方に開口させた液体の通路パイプからなる噴出装置にあって、上記ポンプ機構の下方に垂直な対の第１通路と、第２通路がある直立倒立兼用操作部材を設け、該第１通路の上端は上記ポンプ構の末端に接続させ、下端は接続通路を介して上記液体の通路パイブの上端に接続させ、かつ該接続通路内に、該通路の内径より小径の第１のボール弁体を嵌挿させ、第２通路の末端は上記第１通路の中間部に接続され、上端は容器内の上方に開放されており、この第２通路内には第２通路の内径より小径の第２のボール弁体を嵌挿させたことにある。Thus, the features of the ejector device that can be used even in the upright and inverted states of the present invention are as follows: an ejection cylinder that is provided substantially horizontally at the upper part, ejects liquid, a nozzle body fitted to the tip thereof, and the rear of the ejection cylinder A pump mechanism suspended vertically from the end, a member provided in the ejector body for operating the pump mechanism, and a liquid passage pipe having an upper end attached to the pump mechanism and having an end opened below the container A pair of first passages perpendicular to the lower side of the pump mechanism and an upright and inverted operation member having a second passage, the upper end of the first passage being connected to the end of the pump mechanism And the lower end is connected to the upper end of the liquid passage pipe via the connection passage, and the first ball valve body having a diameter smaller than the inner diameter of the passage is inserted into the connection passage, and the end of the second passage is inserted.

考案の効果Effect of device

而してエアゾールまたはトリガレバーなどによってポンプ機構を作動させ、噴出本体の液体噴出口を開くことにより、当該噴出口に連なる液体容器内の内容物を外部空間に噴出させるようになっているが、その使用時にあって直立状態から倒立状態（所謂さかさまの状態および横倒し状態を含む）での使用となった時、容器内の液体を噴出させることができなくなるような不祥事をなくし、かつ容器内の液体が外部に漏れ出すような虞もなく、安心、安全に使用可能な噴出器を提供することができたのである。Thus, by operating the pump mechanism by aerosol or trigger lever, etc., and opening the liquid jet port of the jet body, the contents in the liquid container connected to the jet port are jetted to the external space. When it is used in an upright state (including the upside-down state and the side-down state) when it is used, it eliminates scandals that prevent the liquid in the container from being ejected. It was possible to provide an ejector that can be used safely and safely without the risk of leakage of the liquid.

考案を実施する為の形態Form for carrying out the invention

次に本案の１実施例を、トリガーレバー使用の形式の噴出装置に適用させたもので説明すると、図で（１）は液体容器（２）の上部に螺合させたごく一般的なトリガー式噴出装置の噴出器本体で、上部に略水平に設けられ液体を噴射する噴出筒（３）と、その先端部を覆うように嵌合させたノズル体（４）と、噴出筒（３）の後端部から垂直に垂下させたポンプ機構（５）と、噴出器本体（１）に設けられ上記ポンプ機構（５）を作動させるトリガーレバー（６）と、上端が上記ポンプ機構（５）に取り付けられ、末端を上記容器（２）の下方に開口させた液体の通路パイプ（７）からなる。Next, one embodiment of the present plan will be described by applying it to an ejection device using a trigger lever. In the figure, (1) is a very general trigger type screwed into the upper part of the liquid container (2). In the ejector body of the ejection device, there are provided an ejection cylinder (3) provided substantially horizontally at the upper part and ejecting liquid, a nozzle body (4) fitted so as to cover the tip, and an ejection cylinder (3). A pump mechanism (5) suspended vertically from the rear end, a trigger lever (6) provided on the ejector body (1) for operating the pump mechanism (5), and an upper end connected to the pump mechanism (5) It consists of a liquid passage pipe (7) which is attached and whose end is opened below the container (2).

而して上記容器（２）内の液体を噴出させる時は、トリガーレバー（６）を回動させることによりポンプ機構（５）内のピストンを作動させ、容器（２）内の液体を通路パイプ（７）内に吸い上げ、噴出筒（３）を経てノズル本体（４）から噴射あるいは噴霧などの噴出操作を行うようになっている。Thus, when the liquid in the container (2) is ejected, the piston in the pump mechanism (5) is operated by rotating the trigger lever (6), and the liquid in the container (2) is passed through the passage pipe. (7) It is sucked into the nozzle body, and an ejection operation such as spraying or spraying is performed from the nozzle body (4) through the ejection cylinder (3).

続いて図示した本案直立および倒立状態でも使用可能な噴出器装置の実施例は、図２及び図３の拡大説明図で示した。即ち（８）は直立倒立兼用操作部材で、垂直な対の第１通路（９）と、第２通路（１０）がある。Subsequently, an example of the ejector apparatus that can be used in the illustrated upright and inverted states is shown in the enlarged explanatory views of FIGS. 2 and 3. That is, (8) is an upright inverted operating member, which has a vertical pair of first passage (9) and second passage (10).

そして図２で、第１通路（９）の上端は上記ポンプ機構（５）の末端に接続され、さらに水平な通路を介して垂直な接続通路（１１）に連設され、その末端は上記液体の通路パイプ（７）の上端が接続されている。In FIG. 2, the upper end of the first passage (9) is connected to the end of the pump mechanism (5), and further connected to the vertical connection passage (11) through a horizontal passage, the end of which is the liquid The upper end of the passage pipe (7) is connected.

上記接続通路（１１）内には該通路（１１）の内径より小径の第１のボール弁体（１２）が嵌挿されている。なおこの接続通路（１１）の上端部は、第１のボール弁体（１２）が上方にあるとき容器（２）内の液体が流れるのに邪魔とならないよう凹所（１３）が設けられ、且つ接続通路（１１）の下端部は上記通路パイプ（７）の上部が内側から嵌挿され、第１のボール弁体（１２）がこの通路パイプ（７）の上端部に密に係合できるようになっている。A first ball valve body (12) having a smaller diameter than the inner diameter of the passage (11) is fitted into the connection passage (11). The upper end of the connection passage (11) is provided with a recess (13) so as not to obstruct the flow of the liquid in the container (2) when the first ball valve body (12) is above. And the upper end of the said passage pipe (7) is inserted from the inner side at the lower end of the connection passage (11), and the first ball valve body (12) can be closely engaged with the upper end of the passage pipe (7). It is like that.

第２通路（１０）の末端は上記第１通路（９）の中間部に接続され、上端は容器（２）内の上方に開放されており、この第２通路（１０）内には第２通路（１０）の内径より小径の第２のボール弁体（１４）が嵌挿されている。The end of the second passage (10) is connected to the intermediate portion of the first passage (9), and the upper end is opened upward in the container (2). The second passage (10) has a second end. A second ball valve element (14) having a smaller diameter than the inner diameter of the passage (10) is inserted.

なお、上記第２通路（１０）の上端部には、第２のボール弁体（１４）が、容器（２）内に飛び出さないように第１の突出部（１５）など設けるのがよく、また第１通路（９）との接続部には第１通路（９）方向に飛び出さないよう第２の突出部（１６）が設けるなどの工夫が必要である。In addition, it is good to provide the 1st protrusion part (15) etc. in the upper end part of the said 2nd channel | path (10) so that the 2nd ball valve body (14) may not jump out in a container (2). Further, it is necessary to devise such as providing the second projecting portion (16) at the connecting portion with the first passage (9) so as not to protrude in the direction of the first passage (9).

また上記第２通路（１０）の上端部は格子状（１７）となし、第２のボール弁体（１４）が第２通路（１０）の上端部にあったときでも、容器（２）内に液体が第２通路（１０）内に入るよう設計されることが重要である。The upper end of the second passage (10) has a lattice shape (17), and even when the second ball valve body (14) is at the upper end of the second passage (10), the inside of the container (2) It is important that the liquid is designed to enter the second passage (10).

而して今通常の直立状態で使用するときは、トリガーレバー（６）を使ってポンプ機構（５）を作動させると、容器（２）内の液体は通路パイプ（７）から接続通路（１１）内の第１のボール弁体（１２）を押し上げ、の周囲から第１の通路（９）を通ってポンプ機構（５）に入り、背圧を受け噴出路（３）を経てノズル体（４）から噴出される。Thus, when the pump mechanism (5) is operated by using the trigger lever (6), the liquid in the container (2) is discharged from the passage pipe (7) to the connection passage (11). The first ball valve body (12) is pushed up, enters the pump mechanism (5) from the periphery of the first ball valve body (12) through the first passage (9), receives the back pressure and passes through the ejection path (3) to the nozzle body ( It is ejected from 4).

なおこの場合容器（２）内の液体は、ポンプ機構（５）の吸引力で同ポンプ機構（５）方向に強制的に向かわされる一方、これと同時に第２の通路（１０）の第１のボール弁体（１４）が第１の通路（９）の下方にあって、該第１通路（９）との連通を阻止しているので、かかる液体が第２の通路（１０）方向に向かうことはない。In this case, the liquid in the container (2) is forcibly directed in the direction of the pump mechanism (5) by the suction force of the pump mechanism (5), and at the same time, the first of the second passage (10). Since the ball valve body (14) is below the first passage (9) and prevents communication with the first passage (9), the liquid is directed toward the second passage (10). I will not head.

続いて図３のように容器（２）が上方で、噴出器（１）が下方の所謂さかさまの状態で使用した場合、容器（２）内の液体は容器（２）の底部ではなく、噴出器（１）方向に溜まった状態になり、同時に第２の通路（１０）の格子状（１７）から第２の通路（１０）内にも浸入している。Subsequently, as shown in FIG. 3, when the container (2) is used in an upward state and the ejector (1) is used in a so-called upside down state, the liquid in the container (2) is not the bottom of the container (2), It is in a state of accumulating in the direction of the ejector (1) and at the same time enters the second passage (10) from the lattice shape (17) of the second passage (10).

ここで、トリガーレバー（６）を使ってポンプ機構（５）を作動させると、この第２通路（１０）の液体が第１の通路（９）を通ってポンプ機構（５）に入り、背圧を受け噴出路（３）を経てノズル体（４）から噴出されることとなる。Here, when the pump mechanism (5) is operated using the trigger lever (6), the liquid in the second passage (10) enters the pump mechanism (5) through the first passage (9), and the back It will be ejected from the nozzle body (4) through the ejection path (3) under pressure.
