Description

本発明は、レバーを押圧して内容液を噴出させるエアゾール式噴出容器に関する。   The present invention relates to an aerosol-type ejection container that presses a lever to eject a content liquid.

毛染め剤などでは、異種液体を収納させた二本のエアゾール缶を左右一対に固定し、二本のエアゾール缶から同時に内容液を噴出させるエアゾール式噴出容器が知られている。かかるエアゾール式噴出容器においては、例えばエアゾール缶のステムを押し下げて内容液を噴出させるヘッド部材と、このヘッド部材を押し下げるレバーを具え、各エアゾール缶のステムを同時に押し下げるようにしている。   As a hair dyeing agent or the like, there is known an aerosol-type ejection container in which two aerosol cans containing different kinds of liquids are fixed in a pair on the left and right sides and the content liquid is ejected simultaneously from the two aerosol cans. Such an aerosol-type ejection container includes, for example, a head member that pushes down the stem of the aerosol can to eject the content liquid and a lever that pushes down the head member, and the stem of each aerosol can is pushed down simultaneously.

特開平１１−３３４７６７号公報Japanese Patent Laid-Open No. 11-334767

しかしながら、エアゾール缶は若干バラツキが生じることは製造上避けられず、組み合わせた一対のエアゾール缶のステムの高さやばね圧などに微妙な違いが生じることがある。するとレバーを押し下げていったとき、一方のエアゾール缶が、他方のエアゾール缶より先に内容液を噴出させたり、また、双方のエアゾール缶から噴出した状態でも、双方の吐出量に差が生じていることがある。   However, slight variations in the aerosol cans are unavoidable in manufacturing, and a slight difference may occur in the height of the stems and spring pressure of the paired aerosol cans. Then, when the lever is pushed down, one aerosol can causes the content liquid to be ejected ahead of the other aerosol can, and even if it is ejected from both aerosol cans, there is a difference in the discharge amount of both There may be.

特に使用者が、初めてこのタイプの容器を使用するとき、液体噴出量がどの程度か解らないため使用者がレバーをゆっくり押し下げ、いずれか一方のエアゾール缶から内容液が噴出した時点でレバーの押し下げを止めてしまうことがあり、片方のエアゾール缶内の液体だけが噴出して、他方のエアゾール缶内の液体の噴出がない、あるいは微量な噴出状態となり、誤った配合比率で噴出させた内容液をそのまま使用してしまう恐れがあった。   Especially when the user uses this type of container for the first time, because the amount of liquid ejected is unknown, the user slowly depresses the lever, and when the liquid is ejected from one of the aerosol cans, the lever is depressed. The liquid in which only the liquid in one aerosol can is ejected and there is no ejection of the liquid in the other aerosol can There was a risk of using it as is.

またヘッド部材は、レバーによって真下方向に押し下げられないと、ヘッド部材が前、あるいは後の壁体に当接し、ヘッド部材の円滑な動きに支障が出ることがある。   Further, if the head member is not pushed down by the lever, the head member may come into contact with the front or rear wall body, which may hinder smooth movement of the head member.

本発明は、レバーの押し下げを確実に行わせ、例えば片方のエアゾール缶からの噴出しか行われないような中途半端なレバーの押し下げを防止して、対になった二本のエアゾール缶の両ステムを確実に押し下げ、エアゾール缶の双方からバランスよく適正な配合比率で内容液を噴出させることができるエアゾール式噴出容器を提供することを目的とする。   The present invention ensures that the lever is pushed down, for example, prevents the half-pushing of the lever from being ejected from one of the aerosol cans, so that both stems of two aerosol cans in pairs It is an object of the present invention to provide an aerosol-type ejection container that can reliably push down the liquid and eject the content liquid from both aerosol cans in a balanced and appropriate mixing ratio.

また、ヘッド部材を円滑に押し下げることができるエアゾール式噴出容器を提供することを目的とする。   Moreover, it aims at providing the aerosol-type ejection container which can push down a head member smoothly.

本発明のエアゾール式噴出容器は、次のように構成した。   The aerosol-type ejection container of the present invention was configured as follows.

１、すなわち内容液を収納し、上部に設けられたステムを押し下げると内容液を噴出させるエアゾール缶と、エアゾール缶の上部に組み付ける保持具と、ステムに嵌合する導入口とその導入口に連通したノズルを具え、保持具に上下動自在に組み付けられたヘッド部材と、ヘッド部材を押し下げるレバーを具え、ヘッド部材の上方で保持具に固定されたレバー部材とからなるエアゾール式噴出容器において、
ヘッド部材の上壁に、後面を湾曲面とし、その湾曲面に段部を形成した凹部を設け、
レバーの下面に、ヘッド部材の凹部の湾曲面に当接する突片を設け、更に突片は、レバーの押し下げにより、段部に一時的に係合した後段部を越えて下降するように構成し、
突片が段部を越えることによりレバーが大きく押し下げられ、ノズルから内容液を噴出させると同時に、レバーの下面がヘッド部材の上壁に当接して打音を発生させることとしてエアゾール式噴出容器を構成した。 1. That is, an aerosol can that contains the content liquid and ejects the content liquid when the stem provided on the upper part is pushed down; a holder that is assembled to the upper part of the aerosol can; an inlet that fits into the stem; In an aerosol-type ejection container comprising a head member that is assembled to a holding tool and a lever member that presses down the head member, and a lever member that is fixed to the holding tool above the head member.
The upper surface of the head member is provided with a concave portion having a curved rear surface and a stepped portion formed on the curved surface.
A projecting piece that contacts the curved surface of the concave portion of the head member is provided on the lower surface of the lever, and further, the projecting piece is configured to descend beyond the rear stage part temporarily engaged with the step part when the lever is pushed down. ,
When the protruding piece exceeds the step, the lever is pushed down greatly, and the liquid is ejected from the nozzle.At the same time, the lower surface of the lever comes into contact with the upper wall of the head member to generate a sound. Configured.

２、１のエアゾール式噴出容器において、ヘッド部材の上壁で、凹部の前方に突部を設け、またレバーの下面に、突部に当接する押圧突部を設け、レバーを押し下げると突部と押圧突部が当接してヘッド部材を押し下げるとともに、突片が湾曲面に当接してヘッド部材が後方に押される力を、押圧突部が突部に当接することにより相殺させることとした。   2 and 1, in the aerosol-type ejection container, a protrusion is provided in front of the recess on the upper wall of the head member, and a pressing protrusion that contacts the protrusion is provided on the lower surface of the lever. While the pressing protrusion comes into contact with the head member and pushes down the head member, the force with which the protruding piece comes into contact with the curved surface and the head member is pushed backward is canceled by the pressing protrusion coming into contact with the protrusion.

３、１と２のエアゾール式噴出容器において、エアゾール缶は、左右に二本並列に配置したエアゾール缶であり、二本のエアゾール缶のステムにヘッド部材を組み付け、同時に押し下げてノズルから内容液を噴出させることとした。   3, 1 and 2 aerosol cans, the aerosol cans are two aerosol cans arranged in parallel on the left and right, the head member is assembled to the stems of the two aerosol cans, and simultaneously pushed down, the content liquid is discharged from the nozzle It was decided to erupt.

本発明のエアゾール式噴出容器は、次のような利点を有している。レバーを押し下げていくと、急にレバーが大きく押し下げられ、内容液の噴出が開始される。また、それに伴って打音が聞こえる。   The aerosol-type ejection container of the present invention has the following advantages. When the lever is pushed down, the lever is suddenly pushed down greatly and the ejection of the content liquid is started. Along with this, a hitting sound is heard.

これにより、使用者は特に意識することなく、自然に必要な位置までレバーを押し下げ内容液を噴出させることができる。また、打音により、レバーが確実に押し下げられたことを確認できる。更に、エアゾール式噴出容器のステムが十分に押し下げられるので、常に内容液が確実に噴出される。   As a result, the user can naturally push the lever down to the required position and squirt the liquid without being particularly conscious. Further, it can be confirmed that the lever is surely pushed down by the hitting sound. Further, since the stem of the aerosol-type ejection container is sufficiently pushed down, the content liquid is always ejected reliably.

更に、ヘッド部材に加えられる前後方向の力は打ち消され、レバーを円滑に作動できる。   Further, the force in the front-rear direction applied to the head member is canceled, and the lever can be operated smoothly.

二連式のエアゾール式噴出容器においては、二本のエアゾール缶の双方から内容液を確実に噴出させることができ、しかも内容液を円滑に噴出できる。   In the double aerosol spray container, the content liquid can be reliably ejected from both of the two aerosol cans, and the content liquid can be smoothly ejected.

図１０にエアゾール式噴出容器２を示す。   FIG. 10 shows an aerosol-type ejection container 2.

エアゾール式噴出容器２は、二本のエアゾール缶４と、エアゾール缶４を固定する固定具６（図１に図示。）と、固定されたエアゾール缶４に組み付ける噴出部８から構成されている。   The aerosol-type ejection container 2 includes two aerosol cans 4, a fixture 6 (shown in FIG. 1) that fixes the aerosol can 4, and an ejection unit 8 that is assembled to the fixed aerosol can 4.

二本のエアゾール缶４は、それぞれ異種の内容液を収納したエアゾール缶で、例えば毛染め剤など内容液を混合して用いる液剤を収納している。尚二本のエアゾール缶４は、同種の液剤を収納したエアゾール缶でもよい。   The two aerosol cans 4 are aerosol cans containing different content liquids, respectively, and contain a liquid agent used by mixing the content liquid such as a hair dye. The two aerosol cans 4 may be aerosol cans containing the same type of liquid agent.

固定具６は、エアゾール缶４の上部を組み付ける孔を二箇所に具え、孔にエアゾール缶４の上部を挿入してエアゾール缶４を並列して固定し、噴出部８に組み付ける。   The fixture 6 is provided with two holes for assembling the upper portion of the aerosol can 4, and the upper portion of the aerosol can 4 is inserted into the hole to fix the aerosol can 4 in parallel and is assembled to the ejection portion 8.

噴出部８は、図２に示すように長円の筒状体である保持具１０と、ノズル１３を具えたヘッド部材１２と、レバー１５を具えたレバー部材１４から構成してある。   As shown in FIG. 2, the ejection portion 8 includes a holder 10 that is an oval cylindrical body, a head member 12 that includes a nozzle 13, and a lever member 14 that includes a lever 15.

保持具１０は、長手方向両側に、固定具６を着脱自在に係止する係止片１６が回動自在に設けてある。保持具１０の短径方向には、ノズル１３を配置させる窪み２０が前方に、またレバー１５を配置させる窪み２２が後方にそれぞれ形成してある。   The holding tool 10 is provided with a locking piece 16 for removably locking the fixing tool 6 on both sides in the longitudinal direction. In the minor axis direction of the holder 10, a recess 20 in which the nozzle 13 is disposed is formed in the front, and a recess 22 in which the lever 15 is disposed is formed in the rear.

保持具１０の上半部は、内筒１１を有する二重構造となっており、内筒１１の下端には、内側に張り出したリブ２９が形成してある。   The upper half of the holder 10 has a double structure having an inner cylinder 11, and a rib 29 projecting inward is formed at the lower end of the inner cylinder 11.

ヘッド部材１２は、内部に導出路３２（図５に示す。）を２箇所具えた長円形で、内筒１１内に、上下動自在に収められている。ヘッド部材１２の前面には導出路３２に連通したノズル１３が取り付けてあり、下面には、エアゾール缶４のステム５を嵌合させる導入口２６が一対、固定具６に組み付けられたエアゾール缶４のステム５に合わせて設けてある。導入口２６は、それぞれ個別に導出路３２の内部に連通し、図４に示すように導出路３２を介してノズル１３に連通している。   The head member 12 is an oval shape having two outlet paths 32 (shown in FIG. 5) therein, and is housed in the inner cylinder 11 so as to be movable up and down. The nozzle 13 communicated with the lead-out path 32 is attached to the front surface of the head member 12, and a pair of introduction ports 26 into which the stem 5 of the aerosol can 4 is fitted are attached to the lower surface of the aerosol can 4 attached to the fixture 6. It is provided in conformity with the stem 5. The introduction ports 26 individually communicate with the inside of the outlet path 32, and communicate with the nozzle 13 through the outlet path 32 as shown in FIG.

ヘッド部材１２の上壁１８の前方には、図３〜５に示すように、前方を高く傾斜させた突部１７が左右対称の位置に設けてある。一方上壁１８の後方には、図３、４に示すように、後方を湾曲面とした凹部１９が設けてある。また湾曲面には突起２１が設けてあり、突起２１により湾曲面に段部が形成されている。   In front of the upper wall 18 of the head member 12, as shown in FIGS. 3 to 5, a protrusion 17 that is inclined forward is provided at a symmetrical position. On the other hand, as shown in FIGS. 3 and 4, a recess 19 having a curved rear surface is provided behind the upper wall 18. In addition, a projection 21 is provided on the curved surface, and a step is formed on the curved surface by the projection 21.

尚ヘッド部材１２は、ノズル１３を含む上半部と、導入口２６を含む下半部を一体に成形し、後方のヒンジ３０で折り曲げ、上下を組み合わせて形成してある。更にヒンジ３０は、ヘッド部材１２が内筒１１の内部で上下動する際のガイドとなっている。   The head member 12 is formed by integrally forming an upper half including the nozzle 13 and a lower half including the inlet 26, bending the hinge 30 at the rear, and combining the upper and lower portions. Further, the hinge 30 serves as a guide when the head member 12 moves up and down inside the inner cylinder 11.

レバー部材１４は、図６にも示すように内筒１１の内部にほぼ一致する長円形に形成してある。レバー部材１４の長手方向両端には、内筒１１の内面に係合する突片３６が設けてある。レバー部材１４の前方には、ノズル１３を通すための切り欠き２７が形成してあり、レバー部材１４の後方には、図７にも示すようにレバー１５がヒンジ２４を介して上下に回動自在に設けてある。   As shown in FIG. 6, the lever member 14 is formed in an oval shape that substantially matches the inside of the inner cylinder 11. Protruding pieces 36 that engage with the inner surface of the inner cylinder 11 are provided at both longitudinal ends of the lever member 14. A notch 27 for passing the nozzle 13 is formed in front of the lever member 14, and the lever 15 is pivoted up and down via a hinge 24 at the rear of the lever member 14 as shown in FIG. It is provided freely.

ヒンジ２４は、図６に示すようにレバー１５の横幅いっぱいに形成されている。これにより、レバー１５は、レバー部材１４に対して左右に傾斜することなく上下方向に回動する。レバー１５は、後部に指置きのための窪みを具え、下面には、突片２３と押圧突部２５が形成してある。   The hinge 24 is formed to the full width of the lever 15 as shown in FIG. As a result, the lever 15 rotates in the vertical direction without tilting left and right with respect to the lever member 14. The lever 15 has a recess for placing a finger on the rear part, and a projecting piece 23 and a pressing projecting part 25 are formed on the lower surface.

突片２３は、レバー部材１４を保持具１０に組み付けたとき凹部１９に対向するよう、２箇所、左右均等に設けてある。そして突片２３は、レバー部材１４を保持具１０に組み付けた状態でレバー１５を押し下げると、凹部１９の湾曲面に先端が当接し、湾曲面に沿って降下する。更に、突片２３は、レバー１５を少し押し下げた時点で突起２１に係合し、かつある程度の力を加えることで突起２１を乗り越えるようになっている。   The projecting pieces 23 are provided at two locations equally on the left and right sides so as to face the recess 19 when the lever member 14 is assembled to the holder 10. Then, when the lever 15 is pushed down with the lever member 14 assembled to the holder 10, the protruding piece 23 comes into contact with the curved surface of the recess 19 and descends along the curved surface. Further, the protrusion 23 is engaged with the protrusion 21 when the lever 15 is pushed down a little, and gets over the protrusion 21 by applying a certain amount of force.

更に、突片２３と突起２１が係合したときは、レバー１５の下面とヘッド部材１２の上壁１８との間に、間隙があり、突片２３が突起２１を越えると、レバー１５がレバー１５の下面と上壁１８が当接するまで下がる。ヘッド部材１２は、ステム５のばね力で上方に付勢されていることによりレバー１５の下面が上壁１８に当接した際、打音が発生する。   Further, when the projecting piece 23 and the projection 21 are engaged, there is a gap between the lower surface of the lever 15 and the upper wall 18 of the head member 12. When the projecting piece 23 exceeds the projection 21, the lever 15 is moved to the lever. The lower surface 15 and the upper wall 18 are lowered until they contact each other. The head member 12 is urged upward by the spring force of the stem 5, so that a hitting sound is generated when the lower surface of the lever 15 comes into contact with the upper wall 18.

押圧突部２５は、レバー部材１４を保持具１０に組み付けたとき突部１７に当接するように２箇所、左右均等な位置に設けてある。押圧突部２５は、レバー１５を押し下げると、ヘッド部材１２を下方に押し下げるとともに突部１７を後方から前方に向けて押し付け、ヘッド部材１２を前方に移動させるように付勢する。   The pressing protrusions 25 are provided at two left and right equal positions so as to contact the protrusions 17 when the lever member 14 is assembled to the holder 10. When the lever 15 is pushed down, the pressing protrusion 25 pushes down the head member 12 and presses the protrusion 17 from the rear to the front, and urges the head member 12 to move forward.

次に、エアゾール式噴出容器２の作用について説明する。   Next, the operation of the aerosol jet container 2 will be described.

図１の状態からレバー１５を押し下げると、押圧突部２５がヘッド部材１２の上壁１８を押し下げ、ヘッド部材１２を押し下げる。また突片２３は、凹部１９内の湾曲面に沿って下降する。そして突片２３が、図８に示すように突起２１に係合すると、突起２１に係合した突片２３によってヘッド部材１２が押し下げられる。尚この時点では、まだステム５は内部の弁が開放されていない。   When the lever 15 is pushed down from the state of FIG. 1, the pressing projection 25 pushes down the upper wall 18 of the head member 12 and pushes down the head member 12. Further, the projecting piece 23 descends along the curved surface in the recess 19. When the projecting piece 23 engages with the projection 21 as shown in FIG. 8, the head member 12 is pushed down by the projecting piece 23 engaged with the projection 21. At this time, the stem 5 has not yet opened its internal valve.

そしてそのまま押し下げを続けて突片２３が突起２１を越えると、図９に示すように突片２３が凹部１９内に入り込むとともにその勢いでレバー１５が押し下げられ、ステム５の弁が完全に開放されるまでヘッド部材１２が一気に押し下げられる。また、突片２３が突起２１を越えるとレバー１５の下面がヘッド部材１２の上壁１８に当接して、打音を発生させる。   When the projection 23 continues to be pushed down and exceeds the projection 21, the projection 23 enters the recess 19 as shown in FIG. 9 and the lever 15 is pushed down by that moment, and the valve of the stem 5 is completely opened. Until then, the head member 12 is pushed down at once. Further, when the projecting piece 23 exceeds the projection 21, the lower surface of the lever 15 comes into contact with the upper wall 18 of the head member 12 to generate a hitting sound.

したがって、突片２３と突起２１の係合が外れ、レバー１５が一気に押し下げられると、二本のエアゾール缶４のステム５の双方が全押しの状態まで確実に押圧され、ノズル１３から適正な配合比率で内容液を噴出させることができる。しかもその際、レバー１５と上壁１８の当接により発生した打音が聞こえ、噴出を確認できる。   Therefore, when the engagement between the protrusion 23 and the protrusion 21 is released and the lever 15 is pushed down all at once, both the stems 5 of the two aerosol cans 4 are surely pressed to the fully-pressed state, and the proper composition is obtained from the nozzle 13. The content liquid can be ejected at a ratio. Moreover, at that time, a hitting sound generated by the contact between the lever 15 and the upper wall 18 can be heard, and the ejection can be confirmed.

更に、レバー１５を押し下げた際、押圧突部２５が突部１７を前方に向けて押し付けるので、突片２３が凹部１９の湾曲面に当接してヘッド部材１２を後方に付勢しても、その力を相殺し、前後方向の力の発生を解消させる。したがって、ヘッド部材１２には真下に向かう力しかかからず、ヘッド部材１２を円滑に上下動させることができる。
尚、上記例では二本のエアゾール缶４を用いたエアゾール式噴出容器２を例に説明したが、本発明は、単一のエアゾール缶に用いてもよい。また、上記例では段部を突起２１で形成したが、本発明は突起に限らず、突片２３が一時的に係止されるものであれば他の手段を用いて段部を形成してよい。 Further, when the lever 15 is pushed down, the pressing protrusion 25 presses the protrusion 17 forward, so that even if the protrusion 23 abuts against the curved surface of the recess 19 and urges the head member 12 backward, The force is offset and the generation of force in the front-rear direction is eliminated. Therefore, the head member 12 is only applied with a force directed downward, and the head member 12 can be smoothly moved up and down.
In the above example, the aerosol jet container 2 using two aerosol cans 4 has been described as an example. However, the present invention may be used for a single aerosol can. In the above example, the step portion is formed by the protrusion 21, but the present invention is not limited to the protrusion, and the step portion may be formed using other means as long as the protrusion piece 23 is temporarily locked. Good.
