Description

【０００１】
【産業上の利用分野】
本発明は、押し下げヘッドを押し下げることにより、液用シリンダ内の液と空気用シリンダ内の空気を合流させて発泡部材を介して発泡させ、噴出口より泡を噴出する泡噴出機構を備えた泡噴出容器であって、泡を比較的遠く迄直線状に噴射させることが可能な泡噴出容器に関する。
【０００２】
【従来の技術】
泡噴出容器として、押し下げヘッドを押し下げることにより、液用シリンダ内の液と空気用シリンダ内の空気を合流させて発泡部材を介して発泡させ、噴出口より泡を噴出する泡噴出機構を備え泡噴出容器が提案されている。
【０００３】
例えば、国際公開番号Ｗ０９２／０８６５７号の如く、上部を大径の空気シリンダに、下部を小径の液体シリンダに、それぞれ形成し、かつ空気シリンダ上部に容器体内への空気供給用弁を設けたシリンダ部材を空気シリンダ上端面を蓋体で密閉させて容器体内へ垂設固定すると共に、上記両シリンダ内へ嵌合させた大小両径ピストンから大小両径ステムを、小径ステム上部を大径ステム内へ嵌着させかつ大径ステムを蓋体に貫通させて起立し、大径ステム上端にノズル付き押し下げヘッドを嵌合した作動部材を上方付勢させて設けたものである。
【０００４】
【発明が解決しようとする課題】
上記従来のこの種容器は、泡の噴出に当たって、手を噴出口近傍に添えて吐出する如く構成されており。その直線状の噴出幅は３〜５ｃｍ程度と一般にあまり大きくない。これらは直線状に比較的長く泡の噴射を考慮していないためで、その噴出口の形状大きさ等に起因するものと思われる。従来のこの種容器の噴出口の口径はその用途によって相違するが一般に５ｍｍφ〜１０ｍｍφ程度の大きさであり、その形状も横長筒状のものが一般的である。
【０００５】
最近では、この種容器の収納物も多様化され、収納物の種類によっては直接目的部位に勢い良く泡を噴射することも求められている。
また、従来のこの種容器では、上記押し下げヘッドから垂下するステム嵌合筒の上部内へ嵌合させる短筒の上下両面ないし一面に発泡用ネットを張設した発泡部材を設けており、また、一般に泡噴出容器から放出される泡はきめの細かい小さい泡であることが望まれていたが、上記収納物の多様化等使用分野が拡大すると、例えば器物吹き付け用洗剤であれば、さほど泡が小径であることを必要とせず、場合によっては更に泡径が大であることが用途に適する場合もある。その泡径は、主として上記発泡部材に張設した発泡用ネットで定めることが出来るが、従来は起泡用の発泡部材は一個だけ嵌合させていたから、上記泡放出用ポンプ容器を各種用途にそれぞれ対応させるためには、発泡される泡径を異にする発泡部材を多数用意することが必要となるものであった。
【０００６】
本発明は上記した点に鑑み、泡を比較的長い距離直線状に噴射することができるとともに、従来既存の容器の極一部を改変することにより得られるため安価に製造できる容器を提案するものである。上記比較的長い直線状距離としては１５ｃｍ以上程度を目安とする。
【０００７】
また、上記目的に加え、組み付け時の操作により、特別の部材を必要とせずに収納液体及び用途に応じた異なる泡径の泡を噴出できる多種類の容器として構成できる容器を提案するものである。
【課題を解決するための手段】
【０００８】
【課題を解決するための手段】
本発明容器は上記課題を解決するため、押し下げヘッド25を押し下げることにより、液用シリンダ８内の液と空気用シリンダ７内の空気を合流させて発泡部材34を介して発泡させ、ヘッドの噴出口より泡を噴出する泡噴出機構を備えた泡噴出容器に於いて、ヘッド噴出口先端に噴射用マウスピース52を付設してなり、上記マウスピース52は、ヘッド噴出口先端部に嵌着固定させた基端部より前方へ縮径する円錐筒状壁53先端に２．０mmφ以下の噴射口54を開口して構成し、また、上記発泡部材 34 が、短筒 34a 上面に発泡用ネット 34b を張設させた発泡部材であり、液と空気の合流点下流の液通路内に上記発泡部材 34 を複数且つ正，倒立嵌着可能に構成した発泡部材嵌着部Ａを設け、該発泡部材嵌着部Ａ内に単数又は複数の発泡部材 34 を嵌着させてなる泡噴出容器として構成した。
【００１０】
【作用】
押し下げヘッド２５を押し下げることにより、空気用シリンダ７内の加圧空気が大径筒状ピストン３５の内筒３６下端縁のシールを開いて通気路２９を通り混合室３３内に導入される。一方、棒状部材４７が下降してその下端の吸い込み弁体４９が液用シリンダ８下端開口を閉じ、液用シリンダ内の液が吐出弁２２を開いて混合室３３内に導入され、空気と混合する。次いで、空気と液の混合物が発泡部材３４を介して発泡され、ノズル先端のマウスピース５２で加速されてその噴射口５４より直線状に噴射される。
【００１１】
また、実験によれば、図１に示す実施例のように、発泡部材嵌合筒３０内へ、短筒３４ａ上面へ発泡用ネット３４ｂを張設した発泡部材３４を上方へ、又同様に設けた発泡部材を倒立させて下方へ、それぞれ嵌着させた場合は、細かい均等な泡の発泡を得ることが出来、また図示しないが、倒立により短筒３４ａ下面に発泡用ネット３４ｂを有する発泡部材３４を一箇だけ発泡部材嵌合筒３０の下部内へ嵌合させた場合は、中径泡の発泡を得ることができ、更に、短筒上端面へ発泡用ネット３４ｂを張設した発泡部材３４を一箇だけ上記嵌合筒３０の上部内へ嵌合させた場合は大径泡の発泡を得ることが出来た。また、一箇だけ嵌合させた発泡部材３４の嵌合位置を順次移動させることで、除々に泡径を変化させることが出来た。
【００１２】
【実施例】
以下、本発明の実施例を図面を参照して説明する。
【００１３】
１は口頚部２を起立する容器体である。
【００１４】
上記口頚部外面へは、装着キャップ３の周壁３ａを螺合させている。該装着キャップは上記周壁を、内側部が段部を介して隆起した頂壁３ｂ周縁から垂下し、その頂壁中央部を開口してその開口周縁から下方へ案内筒４を垂設する。また、頂壁下面の上記案内筒近傍に案内筒よりも長い係止筒５を垂設している。
【００１５】
６はシリンダ部材で、上半を大径の空気用シリンダ７、下半を小径の液用シリンダ８としてそれ等両シリンダをフランジ９で連結し、空気用シリンダの外周上端に付設した外向きフランジ１０を容器体口頚部の上端面と装着キャップ３の頂壁外周部とで挟持させている。外向きフランジ外周からは間隙形成筒１１を起立し、かつ外向きフランジ基端部に小孔１２を穿設している。尚上記間隙形成筒１１を、装着キャップ頂壁外周部から垂下する小筒と装着キャップ周壁の上部とで挟持させている。液用シリンダ下端は下内方へテーパ状に小径化し、かつその下端から吸い上げパイプ嵌合筒１３を垂下し、該筒内へ吸い上げパイプ１４上端を嵌合させている。又上記テーパ状部分内面へは複数支持片１５を縦設し、かつその支持片上方の液用シリンダ下部内面にも支持片内端縁よりも大内径の内端縁を形成する複数突条１６を縦設している。
【００１６】
上記シリンダ部材６からは作動部材１７を起立する。該作動部材は、既述支持片１５上端面へ載置させ、かつ突条１６内面へ下部を嵌合させて液用シリンダ内に設けたコイルスプリング１８により上方付勢させて、液用シリンダ内へ嵌合させた小径筒状ピストン１９からステム２０を起立し、該ステムの上端部外面へ、押し下げヘッドのステム嵌合筒を嵌着させ、又ステム嵌合筒直ぐ下方のステム部分外面へ、小ストローク上下動自在に大径筒状ピストンを嵌合させている。
【００１７】
小径筒状ピストン１９は図示のように筒部２１を起立して該筒部をステム２０の下部内へ嵌着させるとよく、ステム２０は上部内面に玉弁による吐出弁２２を有し、またその中間部に外向きフランジ状壁２３を付設し、該フランジ状壁外周から短筒２４を起立している。
【００１８】
押し下げヘッド２５は、頂壁２５ａ周縁部より垂設した周壁２５ｂ下部を上記案内筒４内に上下動可能に垂下させ、また、頂壁下面中央部よりステム嵌合筒２６を垂下し、そのステム嵌合筒上端内面に基端を開口させて頂壁下面にノズル２７を横設し、該ノズル先端部を周壁を貫通させて前方へ延長させている。また、そのステム嵌合筒２６の下部内は大内径部とし、その上方筒部分下半へステム上端部を嵌着させて、この大内径部とステム外周との間に下向き環状凹部２８を形成している。該ステム嵌着部分内面には複数の溝を縦設した通気路２９を形成し、該通気路は、一端を吐出弁２２下流のステム上端面よりも高い位置に開口し、他端を上記下向き環状凹部２８上端に開口している。
【００１９】
また、本発明では、ステム２０内の吐出弁２２下流に於いて液用シリンダ８から導入される液と、空気用シリンダ７から通気路２９を介して導入される空気との合流点下流に発泡部材を複数且つ，正，倒立嵌着可能に構成した発泡部材嵌着部Ａを設け、該発泡部材嵌着部Ａ内に単数又は複数の発泡部材を嵌着させる如く構成している。
【００２０】
本実施例では、上記ステム嵌合筒２６の上部内へ下部を小外径筒部としてステム上端部内へ挿入させた発泡部材嵌着部Ａとしての発泡部材嵌合筒３０を嵌着させている。その嵌合筒の発泡部材嵌合部分長さは、複数の発泡部材を上下に重ねて嵌合可能な長さに形成する。ステム上端部内へ挿入させた小外径筒部３０ａは、その下端に内向きフランジを有し、該フランジ下面から吐出弁を通過した液体により玉弁が押し上げられて上記内向きフランジのフランジ孔３１を閉塞することがないよう、阻止片３２を垂下する。内向きフランジと吐出弁２２との間には、吐出弁を通過した液体と、通気路２９およびステム上部内面と小外径筒部３０ａ外面との間を通って流出した高圧空気との混合室３３設ける。尚、発泡部材嵌合筒はかならずしも必要ではなく、直接発泡部材をステム嵌合筒の上部内へ嵌合させても良い。
【００２１】
発泡部材３４は、短筒３４ａの上面に発泡用ネット３４ｂを張設して形成する。
【００２２】
短筒外径は発泡部材嵌合筒３０の内面へかた嵌め可能な外径とし、図１が示す実施例では下方発泡部材３４を倒立させ、上方発泡部材３４は正立させている。また図示しないが、例えば、発泡部材嵌合筒３０の下部内に倒立させた発泡部材３４を嵌合させ、また、上記嵌合筒３０上部内に発泡部材を正立させても良い。
【００２３】
大径筒状ピストン３５は、ステム２０の上部外面へ摺動可能に嵌合させた内筒３６と、空気用シリンダ内面へ嵌合させた外筒３７との各中間部に、内筒３６側が高く、外筒３７側が低い、階段付き円筒状フランジ３８の上下両端の水平状板部を連結して形成し、内筒３６に近接するフランジ部分に複数の吸気孔３９を穿設している。内筒３６上端はやや上外方へ拡開する肉薄弾性部となし、その先端を上記下向き環状凹部２８内の外側壁面へ気密に圧接させている。また上方水平板部外周から垂下する垂直筒部内面には複数の突部４０を付設している。更に内筒３６との間に小間隙をおいて、上方の水平状板部からは係止筒４１を起立し、上記小間隙内の水平状板部部分に上記吸気孔３９を穿設している。大径筒状ピストン３５は図１のように既述ステムの外向きフランジ状壁２３の短筒２４内面へ内筒３６下端が嵌合したときを下限とし、又下向き環状凹部２８の外側壁を構成するステム嵌合筒２６下端が大径筒状ピストンの内筒３６と係止筒４１との間へ気密に嵌合して吸気孔３９を密閉したときを上限として、小ストロークだけ、ステム２０に対して上下動可能とする。該小ストロークだけ上下動する範囲で大径筒状ピストンの内筒３６が摺動するステム部分外面に、複数の縦溝４２が穿設してあり、下限まで下降したとき、その溝下端と空気用シリンダ内との連通は大径筒状ピストン内筒下端と外向きフランジ状壁２３との接触で遮断される。
【００２４】
上記大径筒状ピストン３５の内筒３６下半外面へは、吸気弁体４３を嵌合させる。該弁体はその内筒下半外面へ嵌着させた短筒４３ａ下端から斜上外方へ薄肉の弾性外向きフランジ状壁４３ｂを突出しかつ先端部を厚肉部として形成する。またその厚肉部上面を中間水平状板部の下面へ圧接さてせて、吸気弁４４を形成している。
【００２５】
この吸気弁４４は、作動部材１７押し下げの際閉塞したまま下降して空気用シリンダ内を加圧するが、吸気弁体４３が倒立状態で嵌合されていると、その弁体の弾性外向きフランジ状壁４３ｂは大径筒状ピストン３５の垂直筒部内面の突部４０に接してその弁閉塞が不能となるため、上記空気用シリンダ内の加圧が不能となり、そのため加圧の手応えがなく、よって外気吸い込み弁体の不具合を直ちに発見できる如く構成している。
【００２６】
４５は既述装着キャップ３の係止筒５外面へ嵌着させた外気導入弁体で、該弁体は、上記係止筒外面へかた嵌めさせた筒部４５ａ下部外面から上外方へ弾性逆スカート状部４５ｂを突出して、その先端部を空気用シリンダ周壁の上部内面へ圧接させて外気導入弁４６を形成する。又その筒部の下部内面からは、内向きフランジを介して小筒４５ｃを垂下し、図１が示すように作動部材１７が上限にある状態でその小筒４５ｃ内面が大径筒状ピストン３５の下方垂直筒部外面へ水密に圧接するように設けている。
【００２７】
４７は液用シリンダ８の底部内から起立して上部をステム２０下部内へ挿入させる棒状部材で、その下端やや上方から、既述シリンダ下部内面に縦設した支持片１５間へ上下動可能に嵌合させた複数ストッパ４８を突出する。棒状部材４７下端は液体吸い込み弁体４９をなし、該棒状部材下降時にその弁体が、液用シリンダ部の液体吸い込み弁孔を閉塞する。棒状部材上端部は上向きスカート状に拡径形成した摺動部５０として、該摺動部をステム内面に縦設した突条５１内面で強制摺動可能に抱持させている。よって作動部材１７下降時に、ステム２０と棒状部材４７とが共に下降して、棒状部材４７下端が液体吸い込み弁孔を閉塞すると、棒状部材は停止してステム２０を有する作動部材１７だけが下降し、又作動部材上昇の際は、始めステム２０と共に棒状部材４７も上昇するが、ストッパ４８がコイルスプリング１８下面へ接することで棒状部材４７は停止し、以後作動部材１７だけが上昇する。
【００２８】
尚、上記突条５１は、上記小径筒状ピストン１９の筒部２１直上位置から吐出弁２２下部位置までに周方向複数縦設しており、作動部材１７が最上昇位置にある図１の状態では、上記摺動部５０外周が各突条５１部分から外れて上記筒部２１上端内周に周設した突条部２１ａに液密に当接する如く構成し、この部分でステム２０内上下が液密に遮断される。
【００２９】
本発明では押し下げヘッド２５の噴出口としてのノズル２７先端に、噴射用マウスピース５２を付設している。
【００３０】
このマウスピース５２は、噴出口先端部に嵌着固定させた基端部より前方へ縮径する円錐筒状壁５３先端に噴射口５４を開口して構成している。本実施例では、ノズル２７内先端部に嵌着固定させた嵌合筒５５先端よりノズル前面に当接嵌合するフランジ５６を延設してなる基端部を有し、上記嵌合筒５５先端縁より前方へ円錐筒状壁５３を延設するとともに、その先端部に噴射口５４を開口している。
【００３１】
上記噴射口５４の開口径Ｌに関して下記の試験を行った。
【００３２】
試験１
上記に示した泡噴出容器を使用して、マウスピース５２の口径を変化させて泡の噴射状況を測定した。測定は噴射口５４から１５ｃｍ離間した被噴射体に泡を噴射した際の噴射状況を目視で観察し、また、その際のヘッドの押圧感を調べた。結果を以下の表１に示す。
【００３３】

【００３４】
尚、上記の噴射状況の項に於ける○，△，×は、
○…スムーズに直線状に噴射
△…途中で噴射液が湾曲下降
×…更に前方で噴射液が湾曲下降
として判定した。
また、ヘッド押圧は、
○…軽く押圧できる
△…押圧がやや重い
×…押圧がかなり重い
として判定した。
【００３５】
その結果、上記噴射口の開口径が２．０ｍｍφ以下では目的とする少なくとも１５ｃｍの離間距離に直線的に泡を噴射することが出来るため、噴射口の開口径は２．０ｍｍφ以下の大きさが好ましく、また、口径があまり小さくなるとヘッドの押圧が重くなるため、噴射口の口径が１．０ｍｍφ〜２．０ｍｍφであることがより好ましい。
【００３６】
【発明の効果】
本発明は既述構成とするもので、押し下げヘッドの押し下げにより、液用シリンダ内の液と空気用シリンダ内の空気を合流させて発泡部材を介して発泡させ、ヘッドの噴出口より泡を噴出する泡噴出機構を備えた泡噴出容器の改良に係わるものであって、押し下げヘッド噴出口先端部に嵌着固定させた基端部より前方へ縮径する円錐筒状壁先端に２．０ｍｍφ以下の噴射口を開口した噴射用マウスピースを付設したので、噴出される泡は円錐筒状壁部分で加速されて比較的長い距離直線状に噴射することができるものであり、近年の多様化した収納液の用途にマッチしてその要求を充分満たすことができるものである。
【００３７】
また、マウスピースの構造はいたって簡単であり、しかも従来のこの種泡噴出容器に装着固定することにより形成することができるため、生産効率がよく、安価に製造できる利点も兼ね備えている。
【００３８】
また、液と空気の合流点下流の通液路内に発泡部材を複数且つ正，倒立嵌着可能に構成した発泡部材嵌着部を設け、また、短筒上面に発泡用ネットを張設させて発泡部材を構成し、発泡部材嵌着部内へ単数又は複数よりなる発泡部材を嵌着させる如く構成したので、その発泡部材の数，位置及びその発泡部材の正，逆の向きを変えること等により、特別の部材を必要とせずに用途に適した泡径の泡を発泡出来る噴出容器とすることが組み付け時の操作により容易となる。

[Industrial application fields]
The present invention relates to a foam equipped with a foam jetting mechanism in which the liquid in the liquid cylinder and the air in the air cylinder are merged by pushing down the push-down head and foamed through the foaming member, and the foam is ejected from the jet outlet. The present invention relates to an ejection container, which is capable of ejecting bubbles linearly to a relatively long distance.
[0002]
[Prior art]
As a foam ejection container, a foam is equipped with a foam ejection mechanism that causes the liquid in the liquid cylinder and the air in the air cylinder to merge and foam through the foaming member by pushing down the push-down head and eject the foam from the ejection port. A spout container has been proposed.
[0003]
For example, as in International Publication No. W092 / 08657, a cylinder in which the upper part is formed in a large-diameter air cylinder and the lower part is formed in a small-diameter liquid cylinder, and a valve for supplying air into the container body is provided in the upper part of the air cylinder The upper end surface of the air cylinder is sealed with a lid, and the member is suspended and fixed in the container. The large and small diameter pistons are fitted from the large and small diameter pistons fitted into the cylinders, and the upper portion of the small diameter stem is placed in the large diameter stem. And an operating member having a large diameter stem penetrating the lid body and standing upright, and an upper end of the large diameter stem fitted with a push-down head with a nozzle is urged upward.
[0004]
[Problems to be solved by the invention]
The conventional container of the above-described type is configured such that when a bubble is ejected, a hand is attached to the vicinity of the ejection port and discharged. The linear jet width is generally not so large as about 3 to 5 cm. These are linear because they do not take into account the jet of bubbles for a relatively long time, and are considered to be caused by the size of the jet outlet. The diameter of the conventional nozzle of this type varies depending on the application, but generally has a size of about 5 mmφ to 10 mmφ, and the shape is generally a horizontally long cylinder.
[0005]
Recently, the contents stored in this type of container have also been diversified, and depending on the type of the stored goods, it is also required to jet bubbles directly to the target site.
Further, in this type of conventional container, a foaming member is provided in which a foaming net is stretched on both upper and lower surfaces or one surface of a short tube that is fitted into the upper portion of a stem fitting tube that hangs down from the push-down head. In general, it has been desired that the foam discharged from the foam ejection container is a fine, fine foam. However, when the field of use such as diversification of the above-mentioned items expands, for example, in the case of a detergent for spraying a container, the foam is much reduced. It may not be necessary to have a small diameter, and in some cases, a larger bubble diameter may be suitable for the application. The foam diameter can be determined mainly by a foaming net stretched on the foaming member, but since only one foaming foaming member has been fitted in the past, the foam discharge pump container is used for various purposes. In order to make it correspond, it was necessary to prepare many foaming members having different foam diameters.
[0006]
In view of the above points, the present invention proposes a container that can inject bubbles in a straight line for a relatively long distance and that can be manufactured at low cost because it is obtained by modifying a part of a conventional existing container. It is. The relatively long linear distance is about 15 cm or more.
[0007]
Further, in addition to the above object, the present invention proposes a container that can be configured as various kinds of containers that can eject bubbles having different bubble diameters depending on the stored liquid and application without requiring a special member by an operation during assembly. .
[Means for Solving the Problems]
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the container of the present invention pushes down the push-down head 25, so that the liquid in the liquid cylinder 8 and the air in the air cylinder 7 are merged and foamed through the foaming member 34, and the jet of the head In a foam ejection container equipped with a foam ejection mechanism that ejects foam from the outlet, an injection mouthpiece 52 is attached to the tip of the head outlet, and the mouthpiece 52 is fixedly fitted to the tip of the head outlet. An opening 54 having a diameter of 2.0 mmφ or less is opened at the distal end of the conical cylindrical wall 53 that is reduced in diameter forward from the base end portion , and the foam member 34 has a

foam net

34b on the upper surface of the short cylinder 34a. The foam member is provided with a foam member fitting portion A in which a plurality of the

foam members

34 are configured so as to be able to be fitted in a normal and inverted manner in the liquid passage downstream of the confluence of liquid and air. Foam jet formed by fitting one or a plurality of foam members 34 in the fitting portion A Constructed as an exit container.
[0010]
[Action]
By pushing down the push-down head 25, the pressurized air in the air cylinder 7 opens the seal at the lower end edge of the inner cylinder 36 of the large-diameter cylindrical piston 35 and is introduced into the mixing chamber 33 through the air passage 29. On the other hand, the rod-shaped member 47 descends, and the suction valve body 49 at the lower end closes the lower end opening of the liquid cylinder 8, and the liquid in the liquid cylinder opens the discharge valve 22 and is introduced into the mixing chamber 33 to be mixed with air. To do. Next, a mixture of air and liquid is foamed through the foaming member 34, accelerated by the mouthpiece 52 at the tip of the nozzle, and sprayed linearly from the spray port 54.
[0011]
Further, according to the experiment, as in the embodiment shown in FIG. 1, the foam member 34 in which the foam net 34b is stretched on the upper surface of the short cylinder 34a is provided in the foam member fitting cylinder 30 upward and similarly. When the foamed member is turned upside down and fitted downward, it is possible to obtain fine uniform foaming, and although not shown, the foamed member has a foaming net 34b on the lower surface of the short tube 34a. When only one piece 34 is fitted into the lower part of the foaming member fitting cylinder 30, foaming of a medium diameter foam can be obtained, and further, a foaming member in which a foaming net 34b is stretched on the upper end surface of the short cylinder When only one 34 was fitted into the upper part of the fitting cylinder 30, foaming of a large-diameter bubble could be obtained. Moreover, the bubble diameter was able to be changed gradually by moving the fitting position of the foaming member 34 fitted only one piece sequentially.

【The invention's effect】
The present invention has the above-described configuration. When the push-down head is pushed down, the liquid in the liquid cylinder and the air in the air cylinder are merged and foamed through the foaming member, and bubbles are ejected from the ejection port of the head. 2.0 mmφ or less at the distal end of the conical cylindrical wall whose diameter is reduced forward from the base end portion fitted and fixed to the distal end portion of the push-down head ejection port Since the mouthpiece for injection with the opening of the nozzle is attached, the foam that is ejected is accelerated at the conical cylindrical wall portion and can be ejected linearly for a relatively long distance. It matches the intended use of the stored liquid and can fully satisfy its requirements.
[0037]
Moreover, the structure of the mouthpiece is very simple, and since it can be formed by being fixed to this conventional foam ejection container, it has the advantages of high production efficiency and low cost.
