Description
本発明は、容器本体の内容物に対する通路設定部の放出孔から外部空間域への内容物放出量を変更できる内容物放出量切換え機構ならびにこの機構を備えたエアゾール式製品およびポンプ式製品に関する。 The present invention relates to a content discharge amount switching mechanism capable of changing a content discharge amount from a discharge hole of a passage setting portion to a content of a container body to an external space region, and an aerosol type product and a pump type product provided with this mechanism.
特に作動モード設定用の操作部に加えて、放出孔への内容物流入量（＝外部空間域への内容物流出量）を調整するための副操作部を、当該操作部も含めた同時設定操作が可能な形で設けた内容物放出量切換え機構に関する。 In particular, in addition to the operation unit for setting the operation mode, a sub-operation unit for adjusting the amount of content flowing into the discharge hole (= the amount of content flowing into the external space) is set simultaneously, including the operation unit. The present invention relates to a content discharge amount switching mechanism provided in an operable form.
内容物放出孔から外部空間域への内容物流出量を切り換える機構において、その操作がより簡便で、その構成部品点数がより少ないことなどが望ましく、本発明はこのような要請に応えるものである。 In the mechanism for switching the content outflow amount from the content discharge hole to the external space region, it is desirable that the operation is simpler and the number of components is smaller, and the present invention meets such a demand. .
本発明の内容物放出量切換え機構の適用対象はエアゾール式およびポンプ式の各製品である。 The application target of the content discharge amount switching mechanism of the present invention is aerosol type and pump type products.
本明細書においては、内容物放出孔の側を「前」とし、それとは反対側で例えば図示の操作部の側を「後」とする。すなわち、図１(a)，図２(a)，図３(a)および図４の左側方向が「前」で、右側方向が「後」となる。 In the present specification, the content discharge hole side is referred to as “front”, and on the opposite side, for example, the illustrated operation unit side is referred to as “rear”. That is, the left direction in FIGS. 1 (a), 2 (a), 3 (a) and 4 is “front”, and the right direction is “rear”.
本件出願人は、作動モード設定用の操作釦に設定される通路設定部の前端側開口部分に略鞘状の放出孔部材を回動可能な形で取り付け、当該放出孔部材に対する回動操作に基づいて内容物放出量が多い直噴作動モードと、内容物放出量が少ない噴霧作動モードとを選択できるようにした内容物放出量切換え機構を提案している（特許文献１参照）。 The present applicant attaches a substantially sheath-like discharge hole member to the front end side opening portion of the passage setting portion set to the operation button for setting the operation mode in a rotatable manner, and allows the rotation operation to the discharge hole member. Based on this, a direct discharge operation mode with a large content discharge amount and a spray operation mode with a small content discharge amount have been proposed (see Patent Document 1).
この内容物放出量切換え機構では、コイルスプリングの弾性力で内容物放出孔の方に付勢されるスライド部材を操作釦内側の通路設定部に配している。また、放出孔部材の底面部分には内容物渦状化用の溝が形成されている。 In this content discharge amount switching mechanism, a slide member that is biased toward the content discharge hole by the elastic force of the coil spring is disposed in the passage setting portion inside the operation button. In addition, a groove for forming a content vortex is formed on the bottom surface of the discharge hole member.
コイルスプリングの弾性作用によりスライド部材が最大限前方向に移動して放出孔部材の底面部分に当接した状態では、当該底面部分に流入する内容物はもっぱら溝を通って放出孔部へ少量噴霧状態となって流出する。 In a state where the slide member moves forward as much as possible by the elastic action of the coil spring and comes into contact with the bottom surface portion of the discharge hole member, a small amount of the content flowing into the bottom surface portion passes through the groove and sprays to the discharge hole portion. It becomes a state and flows out.
そして、放出孔部材に対する回動操作に基づいてスライド部材をコイルスプリングに抗する形で後退させてその位置に保持する、すなわち放出孔部材の底面部分からスライド部材を離間させた状態では、当該底面部分に流入する内容物が主に（内容物渦状化用の溝ではなく）この離間空間域を通って放出孔部へ多量直噴状態となって流出する。 Then, the slide member is retracted against the coil spring based on the turning operation with respect to the discharge hole member and is held in that position, that is, in a state where the slide member is separated from the bottom surface portion of the discharge hole member, The contents flowing into the part mainly flow out in a large amount of direct injection into the discharge hole through this space (not the contents spiraling groove).
提案済みの上記内容物放出量切換え機構（少量噴射，多量噴射の切換え機構）は、放出孔部材を回動操作するだけで少量噴霧／多量直噴の各作動モードを選択できる、といった利点を有している。 The above-described content discharge amount switching mechanism (switching mechanism between small quantity injection and large quantity injection) has an advantage that each operation mode of small quantity spray / large quantity direct injection can be selected only by rotating the discharge hole member. doing.
ただ、この内容物放出量切換え機構の場合、
(11)少量噴霧／多量直噴の各作動モードの選択操作用の放出孔部材と元々の作動モード設定用の操作部との双方を利用者が片手操作できない、
(12)スライド部材を少量噴霧状態の前方向に設定保持するための弾性部材（コイルスプリング）を用いることにより内容物放出量切換え機構（内容物の少量放出，多量放出の切換え機構）の部品点数が多い、
などの点で改善の余地を残している。
However, in the case of this content release amount switching mechanism,
(11) The user cannot operate both the discharge hole member for selecting the operation mode of the small amount spray / the large amount of direct injection and the operation unit for setting the original operation mode with one hand.
(12) The number of parts of the content discharge amount switching mechanism (switching mechanism for small amount discharge of contents, large amount discharge) by using an elastic member (coil spring) to set and hold the slide member in the forward direction in a small amount spray state There are many,
This leaves room for improvement.
そこで本発明では、作動モード設定用の主操作部と、内容物の少量放出（少量噴射），多量放出（多量噴射）を切り換えるための副操作部とを、利用者の片手による同時設定操作が可能な形で設け、これにより内容物放出量切換え機構の利用者操作上の利便化を図ることを目的とする。 Therefore, in the present invention, the main operation part for setting the operation mode and the sub operation part for switching the small amount discharge (small amount injection) and the large amount discharge (large amount injection) can be simultaneously set by one user's hand. It is provided in a possible form, and it is intended to make it convenient for the user operation of the content discharge amount switching mechanism.
また、スライド部材を少量放出状態に設定保持するためのいわば駆動源として、上述の弾性部材（コイルスプリング）を用いるのではなく、この副操作部に対する利用者の操作力を用い、これにより内容物放出量切換え機構の部品点数の減少化を図ることを目的とする。 In addition, instead of using the above-mentioned elastic member (coil spring) as a drive source for setting and holding the slide member in a small discharge state, the operation force of the user with respect to this sub-operation part is used, thereby The purpose is to reduce the number of parts of the discharge amount switching mechanism.
また、主操作部として、容器本体に取り付けられた操作部保護用のカバー作用部に対して回動可能な第１操作部材を用いるとともに、副操作部として、主操作部に対して回動可能な第２操作部材を用い、これにより主操作部および副操作部の同時設定操作の簡単化を図ることを目的とする。 Moreover, while using the 1st operation member which can be rotated with respect to the cover action part for the operation part protection attached to the container main body as a main operation part, it can be rotated with respect to the main operation part as a sub-operation part. An object of the present invention is to simplify the simultaneous setting operation of the main operation unit and the sub operation unit.
また、内容物少量放出状態を設定する際に副操作部のみを操作するだけでよい、すなわち利用者が副操作部を操作すると主操作部も副操作部の一部で駆動されて作動モード設定操作状態へと移行するようにし、これにより主操作部および副操作部の同時設定操作の一層の簡単化を図ることを目的とする。 In addition, when setting the content small amount discharge state, it is only necessary to operate the sub-operation unit, that is, when the user operates the sub-operation unit, the main operation unit is also driven by a part of the sub-operation unit to set the operation mode. An object is to shift to an operation state, thereby further simplifying the simultaneous setting operation of the main operation unit and the sub operation unit.
また、内部空間域にスライド部材が移動可能な形で配設されて内容物通路域を構成する筒状部に、スライド部材の移動にともなう（内容物通路域ではない）非通路閉空間域のエアの外部空間域との出入りを可能にし、かつ、副操作部に対応した凸状被受け部（スライド部材の一部）の副操作部側への移動を可能にする、ための孔部を形成し、これにより内容物の少量放出状態または多量放出状態の選択的な設定動作の確実化を図ることを目的とする。 In addition, a non-passage closed space region (not a content passage region) that accompanies the movement of the slide member is disposed on the cylindrical portion that is disposed in the internal space region so that the slide member is movable and forms the content passage region. A hole for allowing the air to enter and exit from the external space and for allowing the convex receiving portion (a part of the slide member) corresponding to the sub operation portion to move toward the sub operation portion. The purpose of this is to ensure the selective setting operation of a small amount release state or a large amount release state of the contents.
また、以上の主操作部，副操作部，カバー作用部および筒状部の全体が一体成形された単一部材を用い、これにより内容物放出量切換え機構の組立作業の簡素化および当該機構の部品点数の一層の減少化を図ることを目的とする。 Further, a single member in which the entire main operation portion, sub-operation portion, cover action portion, and cylindrical portion are integrally formed is used, thereby simplifying the assembly work of the content discharge amount switching mechanism and the mechanism. The purpose is to further reduce the number of parts.

この(21)，(22)のいずれの押圧操作においても主操作部７ａが下円筒状部５の薄肉部５ｂをいわば中心にして図示時計方向に回動する。この主操作部の回動にともなってステム３が斜め方向に押下げられる。
In any of the pressing operations (21) and (22), the
ステム３が押下げられるとステム側の周知のバルブ機構がそれまでの閉状態から開状態へと移行して、容器本体１の内容物がステム３および縦孔部８ａを経て噴射用円筒状部８の内容物通路域８ｃに流入する。
When the
この流入内容物はさらにノズル１１の内容物通路域１１ｅを経て放出孔１１ａから外部空間域に噴射される。
This inflowing content is further injected from the
ここで、内容物の流入により内容物通路域８ｃの圧力が高まり、ニードル１２は、その逆スカート部１２ｂの前側面部分が後方への当該圧力を受けて、ノズル１１の放出孔１１ａから離間する後方向へ移動しようとする。

図４の操作部７'の場合、副操作部７ｂ'を押圧して下方斜めへ回動させると、当該副操作部の幅方向両端側に形成された一対の片部７ｄ'が主操作部７ａ'の上面部分を下方に駆動する。
In the case of the
すなわち副操作部７ｂ'のみの押圧操作により、主操作部７ａ'も作動モード操作位置へと移動する。主操作部７ａ'のみが押圧されたとき、副操作部７ｂ'がこれに従動しないことは勿論である。
That is, the
主操作部駆動用の片部７ｄ'が副操作部７ｂ'の幅方向両端側に形成されているので、主操作部７ａ'の操作対象上面の前後方向長さは、片部７ｄ'を有していない主操作部７ａのそれと略同じである。
