Description

【０００１】
【発明の属する技術分野】
本発明は液体噴出器に関する。
【０００２】
【従来の技術】
液体噴出器として種々の形態のものが知られているが、例えば、上面より上方付勢状態で押し下げ可能にステムを突出し、ステムの押し下げにより内蔵吐出弁が開弁してガス圧により収納液を噴出する如く構成したエアゾール容器体２に、筒状の噴出ヘッドやノズル状の噴出ヘッド等を嵌着したものが一般的に使用されている。
【０００３】
前者の例として例えば、下端の導入口をステムに嵌着した縦筒を頂壁裏面より垂設し、縦筒上端に基端を連通したノズルを、頂壁周縁部から垂設した周壁を貫通して横設し、その先端を噴出口として開口したものが挙げられ、また、後者の例として、容器体２胴部外周上端に嵌着させた装着筒にヒンジ部を介して上下揺動可能に押下板を連結するとともに、ステムに下端を密嵌した注出筒の上端を押下板より突設したものが挙げられる。
【０００４】
従来のこの種の液体噴出器は、収納液を使い切った後にもガスが容器体２内に残存しているため、そのまま廃棄すると種々の不都合を引き起こす虞があり、そのため、例えば容器体２胴部を釘等により穿孔してガス抜きを行った後廃棄している。また、噴出ヘッド等を被覆して容器体２に装着するオーバーキャップを備えたものにあっては、そのキャップ上面に特殊構成のガス抜き用突起を形成し、該キャップを使用して廃棄時にガス抜きを行うことも行われている。
【０００５】
【発明が解決しようとする課題】
釘等によるガス抜きは道具を用意しなければならないため面倒であり、穿孔も行い難い。また、後者は特殊構成のオーバーキャップを必要とするため、製造コストもかかり、また、オーバーキャップを必ず設けなければならないという不都合もある。
【０００６】
本発明は、上記した点に鑑みなされたもので、収納液を使い切った後に容器体２内に残存するガスを極めて簡単な操作で排出することができ、ガスの残存による種々の不都合の虞がなく廃棄でき、また、製造も簡単で安価に且つ容易に製造できる液体噴出器を提案するものである。
【０００７】
【課題を解決するための手段】
第１の手段として、以下の通り構成した。即ち、上面より上方付勢状態で押し下げ可能にステム６を突設するとともに、該ステムの押し下げにより内蔵吐出弁が開き、ガス圧で液をステムより噴出する如く構成したエアゾール容器体２と、ステム６に下端の導入口９を嵌合させて押し下げ可能に装着するとともに、側方へ液噴出用のノズル10を突設した噴出ヘッド３とを備えてなる液体噴出器であって、筒壁15上端より縦設してなる切欠凹部16に押し下げ可能にノズル10を突出するとともに、下部を容器体２上部外周に嵌合させて噴出ヘッド周囲に立設した筒部材４を設け、押し下げ状態の噴出ヘッド３を回動してそのノズル10を挿入係止可能な係止溝18を、筒部材４の切欠凹部16側方に連設した。
【０００８】
第２の手段として、以下の通り構成した。即ち、前記第１の手段において、上記係止溝18内へのノズル10の侵入を防止する侵入防止片19を切取可能に設けた。
【０００９】
第３の手段として、以下の通り構成した。即ち、前記第２の手段において、上記侵入防止片19が、係止溝18に破断部20を介して一体に縁部を連結するとともに、指掛部21を延設してなる侵入防止片19である如く構成した。
【００１０】
第４の手段として、以下の通り構成した。即ち、前記第１の手段において、上記ノズル10下面が当接して噴出ヘッド３の押し下げを防止する係止段部22を、切欠凹部16側方に連設した。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【００１２】
図面にある如く本発明の液体噴出器１は、エアゾール容器体２と、噴出ヘッド３と、筒部材４とを備えている。
【００１３】
エアゾール容器体２は、図２にある如く、胴部５の上面より上方付勢状態で押し込み可能にステム６を突出し、該ステムの押し込みにより内蔵吐出弁（図示せず）が開弁してガス圧により容器体２内の収納液をステム６より噴出する如く構成した公知の噴出機構を備えたものが使用でき、一般的なこの種の容器体２を使用できる。図示例では、筒状の胴部５上端をテーパ状に縮径し、その上端縁部にカシメ部分である環状突条７を立設し、該突条外周下部に下向き段部８を周設している。
【００１４】
噴出ヘッド３は合成樹脂等により形成され、ステム６に嵌着してその押し下げ及び液の噴出を行うためのもので、ステム６に下端の導入口９を嵌合させて押し下げ可能に装着するとともに、側方へ液噴出用のノズル10を突設したものである。図示例では、ステム６に下端の導入口９を密嵌させた縦筒11を頂壁12裏面中央部より垂設するとともに、縦筒11上部に基端を開口したノズル10を前方へ延設し、その先端に噴出口13を開口し、この縦筒11とノズル10内を液流路に構成している。また、頂壁12周縁部より下方へ周壁14を垂設している。
【００１５】
筒部材４も合成樹脂等により形成されたもので、筒壁15上端より縦設してなる切欠凹部16に押し下げ可能にノズル10を突出するとともに、下部を容器体２上部外周に嵌合させて噴出ヘッド３周囲に立設している。図示例では、エアゾール容器体２の環状突条７内周に下部を嵌合させた内筒部15a と、環状突条７外周に下部を嵌合させた外筒部15b とを上端の頂板部15c で連結した二重筒状をなしており、前部に切欠凹部16を縦設している。尚、外筒部15b 内周下端部に突設した係合突条17を下向き段部８と係合させて抜け出しの防止を図っている。
【００１６】
また、本発明に於ける筒部材４は、係止溝18を備えている。係止溝18は、収納液を使い切った後に残存するガスを抜くために設けたものであり、押し下げ状態の噴出ヘッド３を回動してそのノズル10を挿入係止可能に構成したものであればその形態は種々採用できる。即ち、押し下げて液が噴出可能な状態の噴出ヘッドを切欠凹部16の位置から回動させて挿入係止させ、エアゾール容器体２の内蔵吐出弁の開弁状態を維持するものである。図１では、切欠凹部16の下部より向かって右方に矩形状の係止溝18を設けているが、後述する侵入防止片により塞がれている。
【００１７】
また、本発明では、図１に示す如く、係止溝18内へのノズル10の侵入を防止する侵入防止片19を切り取り可能に設けても良い。該防止片は、係止溝18にミシン目や薄肉線等の容易に破断が可能な破断部20を介して一体に縁部を連結し、また、指掛部21を一体に延設している。破断部20は縁部の一部或いは全部に設けることができる。また指掛部21は開口縁より外方へ延設しているが、これに限らず、内方、周方向に延設しても良い。そして、必要に応じて指掛部21を掴んで各破断部20を破断して除去し、ノズル10の挿入係止が可能となる如く構成している。この様な侵入防止片は、切取が可能で、且つ、係止溝18内へのノズル10の侵入を防止することができれば、種々の形態を採用することができ、例えば図示しないで説明すると係止溝18の開口部上下を結んで一体に形成された破断が可能な棒状連結片であっても良い。また、この侵入防止片は必ずしも設けなくても良い。
【００１８】
本発明に於ける筒部材４は、不使用時に不用意な液の漏出を防止する目的で係止段部22を設けても良い。係止段部22は、切欠凹部16側方に連設したもので、噴出ヘッド３を回動した際にノズル10下面が当接して噴出ヘッド３の押し下げを防止できるものであればその形態は種々採用できる。更に具体的には、最上昇位置の噴出ヘッド３のノズル10を切欠凹部16の位置から回動させることができ、噴出ヘッド３を押し下げようとした際にその下面が当接して液の噴出を防止することができるものであれば良い。図示例では、切欠凹部16の上端部より向かって左方にノズル10の横幅と略同じ横幅を有する係止段部22を延設している。尚、この係止段部22は必ずしも設けなくても良いが、上記係止溝18とこの係止段部22を両方設ける場合には図示例の如き切欠凹部16から別方向にそれぞれ設けたものに限らず、同一方向に設けることも可能である。また、図中23は指挿入用凹部を示し、噴出ヘッド３の押し下げをより容易に行える如く構成している。
【００１９】
上記の如く構成した噴出器１は、非使用時には図３に示す如く係止段部22にノズル10下面が当接係止されているため、噴出ヘッド３を押し下げようとしても下がらず、収納液の噴出はできない。一方、使用時にはこの状態から図１に示す如くノズル10を切欠凹部16内に回動させると噴出ヘッド３の押し下げが可能となり、液の噴出が可能となる。使用後は再びノズル10を回動させて図３の状態に戻しておく。更に、液を使い切った際には、指掛部21をもち侵入防止片19を切断除去して係止溝18を開口し、噴出ヘッド３を押し下げた状態でそのノズル10を係止溝18に挿入係止させれば、残存するガスを排出することができる。
【００２０】
【発明の効果】
以上説明した如く本発明の液体噴出器は、既述構成としたことにより、収納液を使い切った際には、噴出ヘッド３を押し下げた状態で回動させてそのノズル10を係止溝18内に挿入係止するというきわめて簡単な操作により残存するガスを完全に排出することができ、ガスの残存による種々の不都合の虞がなく廃棄できるものである。しかも、構造が簡単な筒部材を装着するだけでこの様な効果を発揮でき、既成の噴出器をそのまま使用できるため、製造も容易で安価に製造できる利点もある。
【００２１】
また、係止溝18内へのノズル10の侵入を防止する侵入防止片19を切取可能に設けたものにあっては、使用中にノズル10が係止溝18に引っ掛かるなどの不都合がなく、より円滑な液噴出操作を行えるものである。
【００２２】
また、係止溝18に破断部20を介して一体に縁部を連結し、指掛部21を延設してなる侵入防止片19を設けたものにあっては、同様により円滑な液噴出操作を行えるとともに、液を使い切った後の侵入防止片19の切取除去が極めて簡単に行えるものである。
【００２３】
また、ノズル10下面が当接して噴出ヘッド３の押し下げを防止する係止段部22を、切欠凹部16側方に連設したものにあっては、非使用時には噴出ヘッド３の押し下げを防止して液の漏出の不都合を防止でき、使用時には噴出ヘッド３を回動させるという極めて簡単な操作により液の噴出が可能となる利点を兼ね備えている。

Various types of liquid ejectors are known.For example, the stem protrudes so that it can be pushed down from the upper surface, and the built-in discharge valve opens when the stem is pushed down. In general, an aerosol container body 2 configured to be ejected is fitted with a cylindrical ejection head, a nozzle-shaped ejection head, or the like.
[0003]
As an example of the former, for example, a vertical cylinder fitted with a stem at the lower end is suspended from the back of the top wall, and a nozzle communicating with the base end at the upper end of the vertical cylinder penetrates the peripheral wall suspended from the peripheral edge of the top wall. In the latter case, it can be swung up and down via a hinge on a mounting cylinder fitted to the upper end of the outer periphery of the body of the container body 2 as an example. In addition, the press plate is connected to the top, and the upper end of the pouring tube having the lower end closely fitted to the stem is projected from the press plate.
[0004]
In this type of conventional liquid ejector, since gas remains in the container body 2 even after the stored liquid is used up, there is a risk of causing various inconveniences if discarded as it is. Is discarded after being degassed by drilling with a nail or the like. Further, in the case of an apparatus having an overcap that covers the ejection head or the like and is attached to the container body 2, a specially configured gas venting projection is formed on the upper surface of the cap, and the cap is used for gas disposal. Unplugging is also done.
[0005]
[Problems to be solved by the invention]
Degassing with a nail or the like is troublesome because a tool must be prepared, and drilling is difficult. Moreover, since the latter requires an overcap having a special configuration, the manufacturing cost is also increased, and there is a disadvantage that the overcap must be provided.
[0006]
The present invention has been made in view of the above points, and the gas remaining in the container body 2 after exhausting the stored liquid can be discharged by a very simple operation, and there is a risk of various inconveniences due to the remaining gas. The present invention proposes a liquid ejector that can be easily disposed of and can be easily manufactured at low cost and easily.
[0007]
[Means for Solving the Problems]
The first means is configured as follows. In other words, the stem 6 protrudes from the upper surface so as to be able to be pushed down in an upwardly biased state, and the built-in discharge valve is opened by pushing down the stem so that liquid is ejected from the stem by gas pressure, and the stem. 6 is a liquid jetting device including a jetting head 3 having a lower end introducing port 9 fitted thereto so as to be able to be pushed down, and a nozzle 10 for ejecting a liquid projecting laterally. The nozzle 10 protrudes in a notch recess 16 formed vertically from the upper end so as to be able to be pushed down, and the lower part is fitted to the outer periphery of the upper part of the container body 2 and is provided with a cylindrical member 4 standing around the ejection head. A locking groove 18 capable of inserting and locking the nozzle 10 by rotating the head 3 is provided continuously to the side of the cutout recess 16 of the cylindrical member 4.

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
As shown in the drawings, the liquid ejector 1 of the present invention includes an aerosol container body 2, an ejection head 3, and a tubular member 4.
[0013]
As shown in FIG. 2, the aerosol container body 2 protrudes from the stem 6 so that it can be pushed upward from the upper surface of the body 5, and the built-in discharge valve (not shown) is opened by the pushing of the stem. A container equipped with a known ejection mechanism configured to eject the stored liquid in the container body 2 from the stem 6 by pressure can be used, and a general container body 2 of this type can be used. In the illustrated example, the upper end of the cylindrical body 5 is tapered so that an annular ridge 7 that is a caulking portion is erected on the upper end edge, and a downward stepped portion 8 is provided around the outer periphery of the ridge. is doing.
[0014]
The ejection head 3 is formed of a synthetic resin or the like, and is fitted to the stem 6 to push down and eject the liquid. The lower end of the ejection head 9 is fitted into the stem 6 so as to be pushed down. The nozzle 10 for ejecting liquid is projected from the side. In the illustrated example, a vertical cylinder 11 in which an inlet 9 at the lower end is closely fitted to the stem 6 is suspended from the center of the back surface of the top wall 12, and a nozzle 10 having a base end opened at the upper part of the vertical cylinder 11 is extended forward. The nozzle 13 is opened at the tip, and the inside of the vertical cylinder 11 and the nozzle 10 is configured as a liquid flow path. Further, a peripheral wall 14 is suspended downward from the peripheral edge of the top wall 12.
[0015]
The cylindrical member 4 is also formed of a synthetic resin or the like. The nozzle 10 protrudes into a notch recess 16 formed vertically from the upper end of the cylindrical wall 15 so that the nozzle 10 can be pushed down, and the lower part is fitted to the upper outer periphery of the container body 2. It stands up around the ejection head 3. In the illustrated example, an upper tube top portion is formed by an inner tube portion 15a having a lower portion fitted to the inner periphery of the annular ridge 7 of the aerosol container body 2 and an outer tube portion 15b having a lower portion fitted to the outer periphery of the ring ridge 7. It has a double cylindrical shape connected at 15c, and a notch recess 16 is provided vertically at the front. Note that the engagement protrusion 17 projecting from the lower end portion of the inner periphery of the outer cylinder portion 15b is engaged with the downward stepped portion 8 to prevent the withdrawal.
[0016]
Further, the cylindrical member 4 in the present invention is provided with a locking groove 18. The locking groove 18 is provided for removing the gas remaining after the stored liquid is used up. The locking groove 18 is configured to rotate the ejecting head 3 in the depressed state so that the nozzle 10 can be inserted and locked. Various forms can be adopted. That is, the ejection head in a state where the liquid can be ejected by being pushed down is rotated from the position of the notch recess 16 to be inserted and locked, and the open state of the built-in discharge valve of the aerosol container body 2 is maintained. In FIG. 1, a rectangular locking groove 18 is provided on the right side from the bottom of the notch recess 16, but is closed by an intrusion prevention piece described later.
[0017]
Further, in the present invention, as shown in FIG. 1, an intrusion prevention piece 19 for preventing the nozzle 10 from entering the locking groove 18 may be provided so as to be cut off. The prevention piece is formed by integrally connecting an edge portion to the locking groove 18 via a breakable portion 20 that can be easily broken, such as a perforation or a thin-walled wire, and a finger hook portion 21 extending integrally. Yes. The breaking part 20 can be provided in part or all of the edge part. In addition, the finger hooking portion 21 extends outward from the opening edge, but is not limited thereto, and may be extended inward and in the circumferential direction. Then, if necessary, the finger catching portion 21 is grasped and each breaking portion 20 is broken and removed, so that the nozzle 10 can be inserted and locked. Such an intrusion prevention piece can adopt various forms as long as it can be cut and can prevent the nozzle 10 from entering the locking groove 18. It may be a rod-like connecting piece that is integrally formed by connecting the upper and lower openings of the stop groove 18 and can be broken. Moreover, this intrusion prevention piece is not necessarily provided.
[0018]
The cylindrical member 4 in the present invention may be provided with a locking step 22 for the purpose of preventing inadvertent leakage of liquid when not in use. The locking step portion 22 is provided continuously to the side of the notch recess 16, and if the lower surface of the nozzle 10 is brought into contact with the ejection head 3 to rotate and the ejection head 3 can be prevented from being pushed down, its form is Various types can be adopted. More specifically, the nozzle 10 of the ejection head 3 at the highest position can be rotated from the position of the notch recess 16, and when the ejection head 3 is to be pushed down, its lower surface comes into contact with it to eject liquid. Anything that can be prevented is acceptable. In the illustrated example, a locking step 22 having a width substantially the same as the width of the nozzle 10 is extended to the left from the upper end of the notch recess 16. The locking step 22 does not necessarily have to be provided, but when both the locking groove 18 and the locking step 22 are provided, they are provided in different directions from the notch recess 16 as shown in the drawing. However, it is possible to provide the same direction. In the figure, reference numeral 23 denotes a finger insertion recess, which is constructed so that the ejection head 3 can be pushed down more easily.
[0019]
Since the lower surface of the nozzle 10 is in contact with and locked to the locking step portion 22 as shown in FIG. 3 when the ejector 1 configured as described above is not in use, the ejecting head 3 is not lowered even if it is pushed down. Cannot be ejected. On the other hand, when the nozzle 10 is rotated into the notch recess 16 from this state as shown in FIG. 1, the ejection head 3 can be pushed down and the liquid can be ejected. After use, the nozzle 10 is rotated again to return to the state shown in FIG. When the liquid is used up, the intrusion prevention piece 19 is cut and removed by holding the finger catch 21 and the locking groove 18 is opened, and the nozzle 10 is moved into the locking groove 18 while the ejection head 3 is pushed down. If it is inserted and locked, the remaining gas can be discharged.

As described above, the liquid ejector according to the present invention has the above-described configuration, so that when the stored liquid is used up, the ejection head 3 is rotated while being pushed down, and the nozzle 10 is moved into the locking groove 18. Thus, the remaining gas can be completely discharged by an extremely simple operation of inserting and locking it, and can be discarded without causing various inconveniences due to the remaining gas. In addition, such an effect can be exhibited only by mounting a cylindrical member having a simple structure, and since an existing ejector can be used as it is, there is an advantage that manufacture is easy and inexpensive.
[0021]
In addition, in the case where the intrusion prevention piece 19 that prevents the invasion of the nozzle 10 into the locking groove 18 is provided so as to be cut off, there is no inconvenience such as the nozzle 10 being caught in the locking groove 18 during use, A smoother liquid ejection operation can be performed.
[0022]
In addition, in the case where the edge portion is integrally connected to the locking groove 18 via the fracture portion 20 and the intrusion prevention piece 19 formed by extending the finger hook portion 21 is provided, the smoother liquid ejection is similarly performed. In addition to being able to operate, the intrusion prevention piece 19 can be removed and removed very easily after the liquid is used up.
[0023]
In addition, in the case where a locking step portion 22 that is in contact with the lower surface of the nozzle 10 and prevents the ejection head 3 from being pushed down is provided on the side of the notch recess 16, the ejection head 3 is prevented from being pushed down when not in use. Thus, it is possible to prevent the inconvenience of liquid leakage and to have the advantage that liquid can be ejected by an extremely simple operation of rotating the ejection head 3 during use.
