Description

本発明は、エアゾール式製品を対象としたガス抜きモード保持機構に関し、特にエアゾール式製品の作動モード(=内容物噴射状態)と、静止モード(=内容物封止状態)とを選択的に設定するためのアクチュエータを、それと、エアゾール容器のカバー体に設けたガス抜きモード設定部材との係止作用により、ガス抜きモードの位置に簡単,確実に保持するものである。なお、このガス抜きモードは、ステムの動作状態からみると連続作動モードともいえる。   The present invention relates to a degassing mode holding mechanism for aerosol type products, and in particular, selectively sets an operation mode (= content injection state) and a stationary mode (= content sealed state) of an aerosol type product. For this purpose, the actuator for this purpose is easily and reliably held at the position of the gas venting mode by the locking action of the actuator and the gas venting mode setting member provided on the cover body of the aerosol container. Note that this degassing mode can also be said to be a continuous operation mode when viewed from the operating state of the stem.

本明細書では、アクチュエータおよびガス抜きモード設定部材に関する「係止」や「係止作用」の語を、アクチュエータがガス抜きモード設定部材に少なくとも接して受け止められることを示す意で用いる。   In this specification, the terms “locking” and “locking action” related to the actuator and the gas vent mode setting member are used to indicate that the actuator is received at least in contact with the gas vent mode setting member.

また、「アクチュエータ」の語を、作動モード設定用の操作部のみではなく、ステムと連結して内容物を外部空間に噴射するための内容物通路の形成部分を含む、ステム駆動用の作動部の総称として用いる。   In addition, the term “actuator” includes not only an operation unit for setting an operation mode but also an operation unit for driving a stem including a portion for forming a content passage for injecting the content into the external space by being connected to the stem. Used as a general term.

また、容器内容物の放出孔の側を「前」とし、それと反対側を「後」としている。すなわち図1および図2の左側方向が「前」で、右側方向が「後」となる。   Further, the discharge hole side of the container contents is “front”, and the opposite side is “rear”. That is, the left direction in FIGS. 1 and 2 is “front” and the right direction is “rear”.

ガス抜きモード保持機構は、使用済みエアゾールを廃棄するときに初めて必要となり、まだ容器内容物が存在しているエアゾール式製品の使用段階では不要なものである。   The degassing mode holding mechanism is required for the first time when the used aerosol is discarded, and is unnecessary at the use stage of the aerosol type product in which the container contents still exist.

そのため、ガス抜きモード保持機構の形態は、エアゾール式製品の通常の使用段階では内容物噴射動作の障害とならず、また利用者にとっていわば目障りにもならず、そしてガス抜きモードの設定に際しては利用者がその作動状態に簡単にセットできるようになっていることが望ましく、本発明はこの要請に応えるものである。   For this reason, the configuration of the degassing mode holding mechanism does not become an obstacle to the content injection operation in the normal use stage of the aerosol type product, and it is not annoying for the user, and is used when setting the degassing mode. It is desirable for the person to be able to easily set the operating state, and the present invention meets this need.

従来、エアゾール容器のカバー体に設けたガス抜きモード設定部材を用いることにより使用済みエアゾール式製品のガス抜きを行う機構としては、
・ステムに取り付けた噴霧ヘッド(アクチュエータ)の上面の押圧操作部とは別の部分に、当該押圧操作部より高い部分からなる段部を形成し、
・噴霧ヘッドを覆って回動可能なヘッドカバー(カバー体)には、当該アクチュエータの段部に係合する垂直状の押し板(ガス抜きモード設定部材)を固定的に形成した、
ものが提案されている(例えば、特許文献1参照)。
Conventionally, as a mechanism for degassing used aerosol type products by using a degassing mode setting member provided on the cover body of the aerosol container,
-Forming a step part consisting of a part higher than the pressing operation part in a part different from the pressing operation part on the upper surface of the spray head (actuator) attached to the stem,
-A vertical push plate (gas release mode setting member) that engages with the stepped portion of the actuator is fixedly formed on the head cover (cover body) that can rotate by covering the spray head.
The thing is proposed (for example, refer patent document 1).

このガス抜きモード保持機構の場合、ヘッドカバー(カバー体)をエアゾール容器に対して回動操作することにより、当該ヘッドカバーの押し板(ガス抜きモード設定部材)で噴霧ヘッド(アクチュエータ)の段部を押下げ、かつその状態をガス抜きモードとして保持する。
特開2003−165588号公報
In the case of this degassing mode holding mechanism, by rotating the head cover (cover body) with respect to the aerosol container, the stepped portion of the spray head (actuator) is pushed by the push plate (degassing mode setting member) of the head cover. And maintain the state as a degassing mode.
JP 2003-165588 A

このような従来のガス抜きモード保持機構は、ヘッドカバー(カバー体)の回動操作にともなって、当該ヘッドカバーが噴霧ヘッド(アクチュエータ)を押下げることを基本的構成にしている。   Such a conventional degassing mode holding mechanism has a basic configuration in which the head cover pushes down the spray head (actuator) in accordance with the turning operation of the head cover (cover body).

そのため、本来は容器外周面側の凹状部に嵌合させて固定するだけでよい(回動可能にする必要がない単一の)ヘッドカバーを、当該固定用の支持台B1と、この支持台に対して回動する肩カバーB2との別部材で構成しなければならず、ガス抜きモード保持機構の構成が複雑となりその製造にもコストがかかるなどの問題点があった。   Therefore, it is only necessary to fit and fix the concave portion on the outer peripheral surface side of the container (a single head cover that does not need to be rotatable) to the support base B1 for fixing and the support base. On the other hand, it has to be configured by a separate member from the shoulder cover B2 that rotates, and there is a problem that the configuration of the degassing mode holding mechanism is complicated and its manufacturing is costly.

また、利用者がエアゾール式製品をガス抜きモードに設定する場合、一方の手で容器を持って他方の手でヘッドカバーを回動させるといったように両方の手を使わなければならず、ガス抜きモード設定操作上の利便性に欠けるという問題点があった。   In addition, when a user sets an aerosol type product to the degassing mode, the user must use both hands, such as holding the container with one hand and rotating the head cover with the other hand. There was a problem of lack of convenience in setting operation.

そこで、本発明では、エアゾール容器の作動モード設定用のアクチュエータをそのガス抜きモード位置(=作動モード対応位置)に保持するためのスライド部材をカバー体天井部に形成して、ガス抜きモード保持機構の構成の簡単化およびその製造コストの低減化を図ることを目的とする。   Therefore, in the present invention, a slide member for holding the actuator for setting the operation mode of the aerosol container at the degassing mode position (= operation mode corresponding position) is formed on the ceiling of the cover body, and the degassing mode holding mechanism An object of the present invention is to simplify the configuration of the apparatus and to reduce the manufacturing cost thereof.

また、アクチュエータとしてカバー体と一体のレバー式のものを用い、当該アクチュエータの回動基部から遠い部分をガス抜きモード位置のスライド部材で押し下げるようにして、すなわち当該アクチュエータを押し下げる際にその「てこ」作動を利用して、ガス抜きモード設定動作の簡単化を図ることを目的とする。   Also, a lever type integral with the cover body is used as the actuator, and the part far from the rotation base of the actuator is pushed down by the slide member in the gas vent mode position, that is, when the actuator is pushed down, The purpose is to simplify the degassing mode setting operation using the operation.

また、利用者が、エアゾール容器を持った方の片手でこの片部をスライドさせてアクチュエータ(ステム)をガス抜きモードの位置へと移動させることができるようにして、ガス抜きモード設定操作上の利便化を図ることを目的とする。   In addition, the user can slide the one part with one hand holding the aerosol container to move the actuator (stem) to the position of the degassing mode, and the degassing mode setting operation can be performed. The purpose is to improve convenience.

(12) アクチュエータ5は、ステム4を上方向に付勢するコイルスプリング(図示省略)などの作用により上動している。
In still mode (a)
(11) In the slide member 3, the two concave portions 3b formed on the slide surface engage with the two convex portions 2d formed on the slide guide surface of the cover body ceiling portion 2c, respectively. The protrusion 3a for the actuator pressing operation faces the low top surface 5d of the L-shaped passage 5c,
(12) The actuator 5 is moved upward by the action of a coil spring (not shown) that urges the stem 4 upward.

静止モード(a)のエアゾール式製品をガス抜きモード(b)に移行させる場合、利用者は、(21) 操作部5bの押圧操作によりアクチュエータ5を作動モード位置の方に回動させてから、すなわち高天面5eを静止モードの位置よりも下方にシフトさせてからスライド部材3を後方にスライドさせる、
(22) 容器本体1やカバー体2などを把持した手の例えば人差し指でスライド部材3の上面を押しながら後方にスライドさせる、
などの操作をすればよい。
When shifting the aerosol type product in the stationary mode (a) to the degassing mode (b), the user (21) rotates the actuator 5 toward the operation mode position by pressing the operation unit 5b, That is, the slide member 3 is slid rearward after shifting the high ceiling 5e downward from the position of the stationary mode.
(22) The hand holding the container body 1 or the cover body 2 is slid rearward while pressing the upper surface of the slide member 3 with, for example, the index finger.
You can do the following operations.

このスライド部材3に対する後方へのスライド操作にともない、当該スライド部材は、そのかまぼこ形状(曲面形状)の突状部3aがアクチュエータ5(L字状通路部5c)の低天面5dとの対向位置から高天面5eの方へと移動する。   As the slide member 3 slides backward, the kamaboko-shaped (curved surface) protruding portion 3a of the slide member 3 faces the low-top surface 5d of the actuator 5 (L-shaped passage portion 5c). To the high sky surface 5e.

特に(22)の操作の場合は、この移動にともない、スライド部材3の突状部3aの曲面が起立部5fに当たってこれを押下げながら最終的には高天面5eと当接した状態に移行する。なお、起立部5fをテーパ状にすればこの操作がスムーズなものとなる。   In particular, in the case of the operation (22), in accordance with this movement, the curved surface of the projecting portion 3a of the slide member 3 hits the upright portion 5f and finally moves to a state where it abuts against the high ceiling surface 5e while pushing down. To do. In addition, if the upright part 5f is tapered, this operation becomes smooth.

この突状部3aの高天面5eへの移行により、アクチュエータ5(L字状通路部5c)はその接続部5aを中心にして図示反時計方向に回動した状態に保持される。すなわちガス抜きモード(b)の状態に移行する。   Due to the transition of the protruding portion 3a to the high top surface 5e, the actuator 5 (L-shaped passage portion 5c) is held in a state of being rotated counterclockwise in the figure around the connecting portion 5a. That is, the state shifts to the degassing mode (b).

そして、図示のガス抜きモード(b)へ移行した後のスライド部材は、その前方側の凹状部3bがカバー体天井部2cの後方側の凸状部2dと係合し、また、その突状部3aがL字状通路部5cの高天面5eに当接してアクチュエータ5およびステム4をガス抜きモード位置に押下げた状態になっている。 Then, the slide member 3 after the transition to the illustrated degassing mode (b) has the concave portion 3b on the front side thereof engaged with the convex portion 2d on the rear side of the cover body ceiling portion 2c, and the protrusion thereof. The shape portion 3a is in contact with the high top surface 5e of the L-shaped passage portion 5c, and the actuator 5 and the stem 4 are pushed down to the degassing mode position.

スライド部材は、この前方側の凹状部3bと後方側の凸状部2dとの係合作用によりガス抜きモード位置に確実に保持される。 The slide member 3 is reliably held at the degassing mode position by the engaging action of the concave portion 3b on the front side and the convex portion 2d on the rear side.

ガス抜きモードにおいては、ステム4がそれに対する上方向への弾性力に抗して下動し、容器本体1の内部と外部空間とを連通させる周知のステム孔部(図示省略)が開いた作動モードの状態に設定される。   In the degassing mode, the stem 4 is moved downward against the upward elastic force with respect to the stem 4 and an operation in which a well-known stem hole (not shown) that connects the inside of the container body 1 and the external space is opened is opened. Set to the mode state.

したがって容器本体1の残留ガスなどは、概略、容器本体1−ステム孔部−ステム内通路−L字状の通路部5c−共通通路5h−選択通路部5i(短尺ノズル5jまたは長尺ノズル5k)の経路により外部空間に放出される。   Therefore, the residual gas etc. of the container body 1 is roughly as follows: the container body 1—the stem hole portion—the passage in the stem—the L-shaped passage portion 5c—the common passage 5h—the selection passage portion 5i (short nozzle 5j or long nozzle 5k). To the outside space.

図示の選択通路部5iは短尺ノズル5jの使用モードを示している。長尺ノズル5kを用いるには、選択通路部5iを図示時計方向に90度回動させて、共通通路5hに当該長尺ノズルを連通させればよい。なお、長尺ノズル側の通路途中の短尺ノズル通路とのいわば交差部分は、長尺ノズル側通路が短尺ノズル通路を迂回する形になっている。   The illustrated selection passage portion 5i indicates a use mode of the short nozzle 5j. In order to use the long nozzle 5k, the selection passage portion 5i is rotated 90 degrees in the clockwise direction in the drawing, and the long nozzle is communicated with the common passage 5h. It should be noted that at the intersection of the short nozzle passage in the middle of the long nozzle side passage, the long nozzle side passage bypasses the short nozzle passage.

なお、通常の作動モードに設定するにはアクチュエータ5の操作部5bを押圧して、当該アクチュエータを回動させればよい。この回動によりステム4が下動して、上述のようにステム孔部がそれまでの閉状態から開状態へとシフトする。   In order to set the normal operation mode, the operation unit 5b of the actuator 5 may be pressed to rotate the actuator. This rotation causes the stem 4 to move downward, and the stem hole shifts from the closed state to the open state as described above.
