Description

【０００１】
【産業上の利用分野】
本発明は、エアゾール式の噴霧器に関する。
【０００２】
【従来の技術】
噴霧ヘッド押下げにより、エアゾール缶本体の頂板中央部を貫通して起立してその噴霧ヘッドを上端に嵌合するステムが下降し、するとステム下端の吐出弁が開いて上記ヘッドのノズルから噴霧し、又その押下げ解放によるステムおよび噴霧ヘッドの上昇で吐出弁が閉じ噴霧が停止するよう設けたエアゾール式噴霧器は広く多用されているが、特に輸送時において他物に触れて噴霧ヘッドが押下げられ、無用の噴霧をすることを防止するため、別に設けたキャップを嵌合させて該キャップを外さなければ噴霧ヘッドの押下げが出来ないよう設けている。
【０００３】
【発明が解決しようとする課題】
本発明は、エアゾール缶本体上部に肩カバーを、又該肩カバーに噴霧ヘッドを嵌合させて、輸送時等は液体噴出管としてのステムから噴霧ヘッドを外しておき、使用時、肩カバーに対し噴霧ヘッドを回し押下げるとステムに噴霧ヘッドが嵌合して、そのまま噴霧ヘッドを続けて押下げることで噴霧可能としたものであり、従来使用されていたキャップを不要とし、又子供の悪戯等が予想される場合は、噴霧ヘッドを元の位置まで戻すことで、ステムから噴霧ヘッドが外れ、噴霧ヘッドを押下げても噴霧しないよう設けたものである。
【０００４】
【課題を解決するための手段】
第１の手段として、胴部２上端へ外周部を巻締め３した頂板の中央部を貫通して、下降により開弁する吐出弁を下端に有するステム４を上方付勢して起立するエアゾール缶本体１と、上記巻締め３へ、頂壁11外周から垂下する周壁12下端部を嵌着させると共に、上記ステムとステム後方部分との上方偏心頂壁部分を大きく円形に開口13して、該開口周縁からガイド筒14を垂下し、かつ頂壁11上面の前後方向直径部分に凹溝16を、開口前方凹溝部分16a は浅く、かつ開口後方凹溝部分16b は深く穿設した肩カバー10と、上記ガイド筒14内へ嵌合させた上面閉塞の摺動筒21上端から前方突設したノズル22を、該ノズル下面を溝底面に接して開口前方凹溝部分16a 内へ嵌合させると共に、該ノズルのノズル孔22a を後方延長して上記摺動筒の後部内面に縦設した内筒23の筒孔23a 上端と連続させた噴霧ヘッド20とからなり、該噴霧ヘッドを引上げ、肩カバーに対し回動させてノズル22を開口後方凹溝部分16a 内へ浅く嵌合させたとき、内筒筒孔23a の下部内へステム４が気密に、かつステム上端面が筒孔下部内面に付形した下向き段部23b に接して嵌合し、該状態からの噴霧ヘッド押下げによるステム４の下降で上記吐出弁が開弁可能に形成した。
【０００５】
第２の手段として、上記第１手段を有すると共にガイド筒14の上部内面と摺動筒21の下端部外面とに、噴霧ヘッド20引上げによりノズル22下面が肩カバー頂壁11の上面と同一ないし該上面よりも高く引上げられたとき、互いに係合する係合手段15，24を設けた。
【０００６】
【作用】
図１が示す状態でステム４は、噴霧ヘッド20のノズル孔22a と連通する内筒の筒孔23a から外れており、又噴霧ヘッド20のノズル22下面は、肩カバー10の開口前方凹溝部分16a 内の溝底面に接しているため、噴霧ヘッド20は下降できず、ステム４も肩カバー10および噴霧ヘッド20で覆われていて、該ステムが押下げられることはない。
【０００７】
上記図１の状態から図４のように噴霧ヘッド20を引上げ、かつ回動させて図５のようにノズル22を開口後方凹溝部分16b 上方まで移動し該位置で噴霧ヘッド20を押下げすると、ステム４上部は既述内筒23の下部内へ嵌合され、該状態から更に押下げするとステム４も押下げられて吐出弁が開き、該ステム、内筒23、ノズル22内を通ってエアゾール缶本体内液体が噴出され、噴霧する。
【０００８】
押下げ解放により、上方付勢されているステムが上昇すると共に吐出弁も閉じ、ステムと共に噴霧ヘッド20も上昇して図５の位置まで戻る。該状態から再び噴霧ヘッドを引上げしてステム４から外し、図１が示す初の位置まで戻すことが出来る。
【０００９】
【実施例】
本発明のエアゾール式噴霧器は、エアゾール缶本体と、肩カバーと、噴霧ヘッドとからなる。
【００１０】
エアゾール缶本体１は、従来公知のものであり、よって簡単に説明すると、胴部２上端へ頂板外周部を巻締め３し、かつ頂板中央部を貫通して下端に吐出弁を有するステム４を上方付勢して起立する。該ステムは、付勢に抗しての押下げで吐出弁が開き、缶本体内薬液がそのステム内を通って噴出し、上記押下げ解放によりステムが上昇し、かつ吐出弁が閉じて薬液噴出は停止する。
【００１１】
10は肩カバーで、上記巻締め３ヘ、頂壁11外周から垂下する周壁12下端部を回動不能に嵌着させている。頂壁11は、既述ステム４と任意に定めたステム後方部分との上方頂壁部分を偏心させて大きく円形に開口13し、該開口周縁からガイド筒14を垂下する。ガイド筒14後部と周壁12後部とは図示例のように兼用させてもよい。ガイド筒14下半は大内径化して該大内径部上端の下向き段部を、後述噴霧ヘッド抜出し防止用の係合手段15としている。
【００１２】
更に頂壁11上面の前後方向直径部分には凹溝16を、開口13の前方凹溝部分16a は浅く、かつ開口後方凹溝部分16b は深く穿設する。該凹溝部分の深さは、後述噴霧のために噴霧ヘッドのノズルが必要とする下降距離に応じて定める。
【００１３】
噴霧ヘッド20は、既述ガイド筒14内へ上下動および回動可能に嵌合させた上面閉塞の摺動筒21上端から、既述開口前方凹溝部分16a 内へ底部を嵌合させ、かつ下面を溝底面に接したノズル22を突出すると共に、該ノズルのノズル孔22a を、後方延長して上記摺動筒の後部内面に縦設した内筒23の筒孔23a 上端と連続させる。内筒23下端は摺動筒21下端と等しく設け、かつ内筒の筒孔23a 下端は大内径化して既述ステム４上部を気密に嵌合可能とし、かつその大内径部分上端にはステム上端面を係合させる下向き段部23b を付形している。摺動筒21下端外面には抜出し防止用の係合手段24を設けている。
【００１４】
噴霧ヘッド20は、図１、図３が示す状態から図４が示すように、ノズル22下面が開口前方凹溝部分16a から外れるまで肩カバー10に対して引上げ可能であり、このとき係合手段15,24 が係合して摺動筒21の抜出しが防止され、該図４の状態から噴霧ヘッド20を、ノズルが開口後方凹溝部分16b 上方へ位置するまで回動させ、該位置から噴霧ヘッドを押下げすると、図５が示すようにノズル底部が上記後方凹溝部分内へ浅く嵌合すると共にステム４上部が内筒筒孔23a の下部内へ気密に嵌合し、かつステム上端面が筒孔下部内面の下向き段部23b に接して、ステム４に対する噴霧ヘッド20の下降を不能とする。該状態から更に噴霧ヘッド20を押下げすると、ノズル22は開口後方凹溝部分16b 下方まで押下げられ、又上記下向き段部23b がステム４を押下げてステム下方の吐出弁が開き、ステム４、内筒筒孔23a 、ノズル孔22a を通って噴霧するよう設けている。
既述肩カバー10と噴霧ヘッド20とは、共に合成樹脂材でそれぞれ一体成形すればよい。
【００１５】
【発明の効果】
本発明は既述構成とするもので、噴霧ヘッド20のノズル22を開口前方凹溝部分16a 内へ嵌合させた状態では、該ノズル下面が溝底面に接するため噴霧ヘッド20の押下げが不能であると共に、ノズル孔22a と連通する内筒23の筒孔23a からステム４が外れているから、又該ステムは、エアゾール缶本体の頂板外周の巻締め３へ周壁下端を嵌着させた肩カバー10と、該肩カバー頂壁の開口周縁から垂設したガイド筒14内へ嵌合する摺動筒21付きの噴霧ヘッド20とで、覆われているため、該ステムが他物に押される等して不用意に押下げられるおそれは全くなく、よって該状態では安全に輸送等行うことが出来、又使用に際しては、噴霧ヘッド20を引上げ、かつ回動させてノズル22を開口後方凹溝部分16b 上方まで移動させて僅かに押下げるだけで内筒23の筒孔下部内へステム４上部が水密に嵌合され、かつステム上端面が筒孔23a 内面の下向き段部23b に係合するから、又上記後方凹溝部分16b は深く穿設してステムから液体噴出するまで噴霧ヘッド20を押下げ可能であるから、噴霧不能状態から噴霧可能に操作すること、およびその逆操作も容易である。又使用後に上記逆操作を行っておくことで幼児等の悪戯も防止することが出来る効果がある。又肩カバー頂壁の開口13は、ステム４とステム後方部分との上方偏心頂壁部分へ穿設してあり、かつその開口周縁から垂下するガイド筒14内へ噴霧ヘッドの摺動筒21を嵌合させて、該摺動筒上端から前方突出するノズル22のノズル孔22a を後方へ延長して、上記摺動筒の後部内面に縦設した内筒23の筒孔23a と連通させたから、図５が示すように、噴霧操作可能状態ではノズル先端部が肩カバー周壁12から後方へ突出することとなり、従って図１と図５との比較から明白であるように、肩カバー周壁外面からのノズル先端部突出長さをみることで、噴霧操作が不能な位置へ噴霧ヘッドが戻してあるか否かを見分けることが容易である。
【００１６】
請求項２の場合は上記効果を有するほか、肩カバーのガイド筒14の上部内面と噴霧ヘッドの摺動筒21下端外面とに、噴霧ヘッド引上げによりノズル22下面が肩カバー頂壁11の上面よりも高く引上げられたとき、互いに係合する係合手段15，24を設けたから噴霧ヘッドの抜出しを防止できると共に、上記係合位置でそのまま噴霧ヘッドを回動して、噴霧操作可能位置と噴霧操作不能位置とへのノズル移動を容易に行うことが出来る。

[0002]
[Prior art]
When the spray head is pushed down, the stem that stands up through the center of the top plate of the aerosol can body and fits the spray head to the upper end descends, and then the discharge valve at the lower end of the stem opens and sprays from the nozzle of the head. In addition, the aerosol type sprayer provided so that the discharge valve closes and the spraying stops when the stem and spray head rise due to the release of the press down is widely used. In order to prevent unnecessary spraying, the spray head is not pushed down unless a cap provided separately is fitted and the cap is removed.
[0003]
[Problems to be solved by the invention]
In the present invention, a shoulder cover is fitted to the upper portion of the aerosol can body, and a spray head is fitted to the shoulder cover, and the spray head is removed from the stem as a liquid jet pipe during transportation and the like. When the spray head is turned and pushed down, the spray head fits into the stem and can be sprayed by continuing to push down the spray head as it is, eliminating the need for previously used caps and child mischief. In such a case, the spray head is removed from the stem by returning the spray head to the original position, and the spray head is not sprayed even if the spray head is pushed down.
[0004]
[Means for Solving the Problems]
As a first means, an aerosol can that stands up by upwardly biasing a stem 4 having a discharge valve at its lower end that passes through a central portion of a top plate that has an outer peripheral portion tightened 3 to the upper end of the body portion 2 and opens by lowering. The lower end of the peripheral wall 12 that hangs down from the outer periphery of the top wall 11 is fitted to the main body 1 and the tightening 3, and the upper eccentric top wall portion between the stem and the stem rear portion is opened in a large circle 13. The shoulder cover 10 hangs down the guide tube 14 from the periphery of the opening, and has a groove 16 in the front-rear diameter portion of the top wall 11, the opening front groove portion 16a is shallow, and the opening rear groove portion 16b is deeply drilled. And a nozzle 22 projecting forward from the upper end of the top-closed sliding cylinder 21 fitted into the guide cylinder 14 is fitted into the opening front concave groove portion 16a with the nozzle lower surface in contact with the groove bottom surface. The nozzle hole 22a of the nozzle is extended rearward and vertically provided on the rear inner surface of the sliding cylinder. When the nozzle 22 is shallowly fitted into the opening rear groove portion 16a by pulling up the spray head and turning it with respect to the shoulder cover, the upper end of the cylinder hole 23a of the cylinder 23 is continuous with the spray head 20. The stem 4 is fitted into the lower part of the inner cylinder hole 23a in an airtight manner and the upper end surface of the stem is in contact with a downward stepped part 23b formed on the inner surface of the lower part of the cylinder hole. The discharge valve is formed to be openable by lowering.
[0005]
As a second means, the lower surface of the nozzle 22 is the same as that of the upper surface of the shoulder cover top wall 11 by pulling up the spray head 20 on the upper inner surface of the guide tube 14 and the lower end outer surface of the slide tube 21. Engaging means 15 and 24 are provided that engage with each other when pulled higher than the upper surface.
[0006]

Since it is in contact with the bottom surface of the groove in 16a, the spray head 20 cannot be lowered, and the stem 4 is also covered with the shoulder cover 10 and the spray head 20, and the stem is not pushed down.
[0007]
When the spray head 20 is pulled up and rotated as shown in FIG. 4 from the state shown in FIG. 1 and the nozzle 22 is moved to the upper part of the opening rear concave groove portion 16b as shown in FIG. The upper part of the stem 4 is fitted into the lower part of the inner cylinder 23 described above. When the stem 4 is further pushed down from this state, the stem 4 is also pushed down and the discharge valve is opened, and passes through the stem, the inner cylinder 23 and the nozzle 22. The liquid in the aerosol can body is ejected and sprayed.
[0008]
By pressing and releasing, the upwardly biased stem rises and the discharge valve closes, and the spray head 20 rises together with the stem to return to the position shown in FIG. From this state, the spray head can be pulled up again and removed from the stem 4 to return to the initial position shown in FIG.
[0009]
【Example】
The aerosol sprayer of the present invention comprises an aerosol can body, a shoulder cover, and a spray head.
[0010]
The aerosol can body 1 is a conventionally known one. Therefore, a brief description will be given.

Erect upward and stand up. When the stem is pushed down against the bias, the discharge valve opens, the chemical solution in the can body is ejected through the stem, the stem is raised by the release of the push down, and the discharge valve is closed to close the chemical solution. The eruption stops.
[0011]
10 is a shoulder cover, and the lower end portion of the peripheral wall 12 hanging from the outer periphery of the top wall 11 is non-rotatably fitted to the above-described winding fastening 3. The top wall 11 has a large circular opening 13 by eccentrically deviating the upper top wall portion of the stem 4 described above and the arbitrarily determined stem rear portion, and the guide tube 14 is suspended from the periphery of the opening. The rear part of the guide tube 14 and the rear part of the peripheral wall 12 may be combined as in the illustrated example. The lower half of the guide cylinder 14 has a large inner diameter, and the downward stepped portion at the upper end of the large inner diameter portion is used as an engagement means 15 for preventing a spray head from being pulled out later.
[0012]
Further, a groove 16 is formed in the front-rear direction diameter portion of the top surface of the top wall 11, the front groove portion 16a of the opening 13 is shallow, and the opening groove portion 16b is deeply formed. The depth of the concave groove portion is determined according to the descending distance required by the nozzle of the spray head for spraying described later.
[0013]
The spray head 20 is fitted into the above-described opening front concave groove portion 16a from the upper end of the top-closed sliding cylinder 21 fitted in the above-described guide cylinder 14 so as to be vertically movable and rotatable, and The nozzle 22 whose bottom surface is in contact with the bottom surface of the groove protrudes, and the nozzle hole 22a of the nozzle extends rearward so as to be continuous with the upper end of the cylinder hole 23a of the inner cylinder 23 provided vertically on the rear inner surface of the sliding cylinder. The lower end of the inner cylinder 23 is provided to be equal to the lower end of the sliding cylinder 21, and the lower end of the inner cylinder hole 23a is increased in inner diameter so that the upper portion of the stem 4 can be hermetically fitted. A downward stepped portion 23b for engaging the end face is shaped. Engaging means 24 for preventing withdrawal is provided on the outer surface of the lower end of the sliding cylinder 21.
[0014]
As shown in FIG. 4 from the state shown in FIGS. 1 and 3, the spray head 20 can be pulled up with respect to the shoulder cover 10 until the lower surface of the nozzle 22 comes off the opening front groove portion 16a. 15 and 24 are engaged to prevent the sliding cylinder 21 from being pulled out. From the state shown in FIG. 4, the spray head 20 is rotated until the nozzle is positioned above the opening rear groove portion 16b, and spraying is started from this position. When the head is pushed down, as shown in FIG. 5, the bottom of the nozzle fits shallowly into the rear concave groove, and the upper portion of the stem 4 fits airtightly into the lower portion of the inner cylindrical tube hole 23a. Comes into contact with the downward step portion 23b of the inner surface of the lower part of the cylindrical hole and makes it impossible to lower the spray head 20 with respect to the stem 4. When the spray head 20 is further pushed down from this state, the nozzle 22 is pushed down below the opening rear groove 16b, and the downward step 23b pushes down the stem 4 to open the discharge valve below the stem. The inner tube hole 23a and the nozzle hole 22a are provided for spraying.
The shoulder cover 10 and the spray head 20 described above may be integrally formed of a synthetic resin material.
[0015]
【The invention's effect】
The present invention is configured as described above, and when the nozzle 22 of the spray head 20 is fitted into the opening front concave groove portion 16a, the lower surface of the nozzle is in contact with the bottom surface of the groove, so that the spray head 20 cannot be pushed down. Since the stem 4 is removed from the cylindrical hole 23a of the inner cylinder 23 communicating with the nozzle hole 22a, the stem also has a shoulder with a lower end of the peripheral wall fitted to the winding 3 on the outer periphery of the top plate of the aerosol can body. Since the cover 10 is covered with the spray head 20 with the sliding cylinder 21 fitted into the guide cylinder 14 suspended from the opening peripheral edge of the shoulder cover top wall, the stem is pushed by another object. In this state, it can be safely transported and the like, and in use, the spray head 20 is lifted and rotated to turn the nozzle 22 into the rear recessed groove. Portion of the inner cylinder 23 just by moving the part 16b upward and pushing it down slightly Since the upper part of the stem 4 is watertightly fitted into the part and the upper end surface of the stem is engaged with the downward step part 23b of the inner surface of the cylindrical hole 23a, the rear concave groove part 16b is deeply drilled to eject liquid from the stem. Since the spray head 20 can be pushed down to the minimum, it is easy to operate so as to enable spraying from a non-sprayable state and vice versa. Further, by performing the reverse operation after use, there is an effect that it is possible to prevent mischief of an infant or the like. The opening 13 in the top wall of the shoulder cover is formed in the upper eccentric top wall portion of the stem 4 and the rear portion of the stem, and the sliding cylinder 21 of the spray head is inserted into the guide cylinder 14 depending from the periphery of the opening. Since the nozzle hole 22a of the nozzle 22 protruding forward from the upper end of the sliding cylinder is extended rearward and communicated with the cylindrical hole 23a of the inner cylinder 23 provided vertically on the rear inner surface of the sliding cylinder, As shown in FIG. 5, the nozzle tip protrudes rearward from the shoulder cover peripheral wall 12 in the sprayable state, so that it is clear from the comparison between FIG. 1 and FIG. By looking at the protruding length of the nozzle tip, it is easy to determine whether or not the spray head has been returned to a position where the spray operation is impossible.
[0016]
In the case of claim 2, in addition to the above effects, the lower surface of the nozzle 22 is lifted from the upper surface of the shoulder cover top wall 11 by pulling up the spray head on the upper inner surface of the guide tube 14 of the shoulder cover and the outer surface of the lower end of the sliding tube 21 of the spray head. Since the engaging means 15 and 24 that engage with each other are provided, the spraying head can be prevented from being pulled out, and the spraying head can be rotated as it is in the above-mentioned engaging position, so that the sprayable position and the spraying operation can be performed. The nozzle can be easily moved to the impossible position.
