Description

本発明は、エアゾール式製品の容器本体に収容された内容物を外部空間域へ放出するためのステム,ステムガスケットおよびハウジングなどの関連構成を対象とした内容物放出機構に関する。 The present invention relates to a content release mechanism for related configurations such as a stem, a stem gasket, and a housing for discharging the contents contained in the container body of an aerosol-type product to an external space area.

特にステムガスケットの中央開口下端側およびその外近傍底面からなる環状の下中央エッジ部分において、静止モードの、下広がりテーパ面状のステム環状肩部との常時密接にともなう外方への過度な倣い変形を生じない、ようにした内容物放出機構に関する。 In particular, at the lower center edge portion of the ring consisting of the lower end side of the central opening of the stem gasket and the bottom surface near the outer side thereof, excessive outward copying is always closely associated with the downward spreading tapered surface-shaped stem ring shoulder in the stationary mode. It relates to a content release mechanism that does not cause deformation.

なお、静止モードにおいてステムガスケットの中央開口下端側などとの当接係止状態に設定されるステム環状肩部は、ステムを、ステムガスケットから抜けることなくその静止モードに位置決めして保持するための構成要素である。 The stem annular shoulder, which is set in the contact-locked state with the lower end of the central opening of the stem gasket in the stationary mode, is used to position and hold the stem in the stationary mode without coming off the stem gasket. It is a component.

本明細書では適宜「ステムガスケットの中央開口下端側およびその外近傍底面からなる環状の下中央エッジ部分」を単に「ガスケット下中央エッジ部分」といい、「下広がりテーパ面状のステム環状肩部」を単に「ステム環状肩部」または「環状肩部」という。 In the present specification, the "annular lower central edge portion consisting of the lower end side of the central opening of the stem gasket and the bottom surface near the outer side thereof" is simply referred to as "the lower central edge portion of the gasket", and "the stem annular shoulder portion having a downward spreading tapered surface shape". Is simply referred to as "stem annular shoulder" or "annular shoulder".

また、ステムの長手方向、すなわち各図の上下方向を「縦」,「上下」といい、これと直交する方向を「横」という。 Further, the longitudinal direction of the stem, that is, the vertical direction of each figure is referred to as "vertical" and "vertical", and the direction orthogonal to this is referred to as "horizontal".

本発明の内容物放出機構は、ガスケット下中央エッジ部分を、ステム環状肩部とその下端側から下外方に延びる縦リブ状部の水平上面とでいわば分散して受けることにより、ステム環状肩部が過度にステムガスケットへ食い込むのを阻止している。 In the content release mechanism of the present invention, the central edge portion under the gasket is distributed and received by the stem annular shoulder portion and the horizontal upper surface of the vertical rib-shaped portion extending downward and outward from the lower end side thereof, so that the stem annular shoulder portion is received. It prevents the part from excessively biting into the stem gasket.

この過度な食込み阻止によってガスケット下中央エッジ部分のステム倣い変形が少しでも抑えられ、ステムの直円筒状部および環状肩部の各外周面と、ステムガスケットの内周面との間の良好な初期シール状態が内容物放出機構の多回数使用後も維持されやすい。 This excessive bite prevention suppresses stem-like deformation of the lower central edge of the gasket as much as possible, and a good initial stage between the outer peripheral surfaces of the straight cylindrical portion and the annular shoulder portion of the stem and the inner peripheral surface of the stem gasket. The sealed state is easily maintained even after multiple uses of the content release mechanism.

また、ステム環状肩部の下端部分の下側には縦リブ状部間のテーパ状底面付きの縦凹状スペースを連続設定し、このスペースに、作動モードから静止モードへの復帰時にステムガスケットでかき落とされるステム外周面の付着内容物をいわば仮収容している。 In addition, a vertically concave space with a tapered bottom surface between the vertical ribs is continuously set under the lower end of the stem annular shoulder, and this space is scratched with a stem gasket when returning from the operating mode to the stationary mode. The contents attached to the outer peripheral surface of the stem that are dropped are temporarily stored.

この縦凹状スペースに、ステム外周面(直円筒状部外周面および環状肩部外周面)からの被かき落し内容物を収容することにより、作動モード終了後にこの被かき落し内容物がステムガスケットとステム外周面との間に挟み込まれにくい形に設定している。 By accommodating the scraped contents from the outer peripheral surface of the stem (the outer peripheral surface of the linear cylindrical portion and the outer peripheral surface of the annular shoulder portion) in this vertically concave space, the scraped contents become the stem gasket after the operation mode is completed. The shape is set so that it is not easily pinched between the stem and the outer peripheral surface.

縦凹状スペースに仮収容された内容物はそのテーパ状底面を経てハウジングの底面側内部空間域に落下する。 The contents temporarily housed in the vertically concave space fall into the internal space area on the bottom surface side of the housing via the tapered bottom surface.

エアゾール式製品のステムに、ステム環状肩部と、その下端部分から下方に連続する縦凹状スペースとを設けること自体はすでに提案されている(特許文献1参照)。 It has already been proposed that the stem of an aerosol-type product is provided with an annular shoulder portion of the stem and a vertically concave space continuous downward from the lower end portion thereof (see Patent Document 1).

この静止モードにおけるステムガスケットの中央開口周面は、特許文献1の図4および図5で明示されるように、もっぱらステム環状肩部上端側のステム直円筒状部に密接するだけであって、ステム環状肩部の傾斜部〔1b〕には密接していない。 The central opening peripheral surface of the stem gasket in this stationary mode is only in close contact with the stem straight cylindrical portion on the upper end side of the stem annular shoulder portion, as is shown in FIGS. 4 and 5 of Patent Document 1. It is not in close contact with the inclined part [1b] of the stem annular shoulder.

静止モードのステムを積極的に保持してステムガスケットから上方へと抜けないようにしているのは、ステムガスケットの下面外端部分に設けられた係止リング〔9〕である。また、これに係止されるのはステムガスケットの突起〔1e〕の上端面となる。 It is a locking ring [9] provided at the outer end of the lower surface of the stem gasket that positively holds the stem in the stationary mode and prevents it from coming out of the stem gasket upward. Further, what is locked to this is the upper end surface of the protrusion [1e] of the stem gasket.

上記従来の内容物放出機構の場合、作動モードから静止モードへの復帰時にステムガスケットの中央開口周面がステム環状肩部と当接することはない。 In the case of the conventional content release mechanism, the peripheral surface of the central opening of the stem gasket does not come into contact with the stem annular shoulder portion when returning from the operating mode to the stationary mode.

そのため、作動モードにおいてステム環状肩部の外周面に付着した内容物が静止モードへの復帰時にステムガスケットの中央開口周面で掻き落とされるといった動作は生じえない。 Therefore, in the operation mode, the contents adhering to the outer peripheral surface of the stem annular shoulder portion cannot be scraped off by the peripheral surface of the central opening of the stem gasket when returning to the stationary mode.

すなわち、ステム環状肩部への付着内容物や、ステム直円筒状部に付着していてステムガスケットの中央開口周面により掻き落とされた内容物が、ステム環状肩部で堆積するという問題点があった。 That is, there is a problem that the contents adhering to the stem annular shoulder portion and the contents adhering to the stem straight cylindrical portion and scraped off by the central opening peripheral surface of the stem gasket are deposited on the stem annular shoulder portion. there were.

本発明は、静止モードにおける上述のガスケット下中央エッジ部分を、ステム環状肩部と、その下端側から下外方に連続する周方向飛び飛びの縦リブ状部の水平上面で受けて、ステム環状肩部の付着内容物の除去およびステム位置決めの確実化を図ることを目的とする。 In the present invention, the above-mentioned central edge portion under the gasket in the stationary mode is received by the horizontal upper surface of the stem annular shoulder portion and the vertical rib-shaped portion that is continuous from the lower end side to the lower outer side, and the stem annular shoulder portion. The purpose is to remove the adhered contents of the part and to ensure the positioning of the stem.

また、静止モードのガスケット下中央エッジ部分の受け作業をステム環状肩部と縦リブ状部水平上面とで共同負担し、これによりステム環状肩部の径方向長さがそれ単独の場合よりも短縮されてこのエッジ部分の倣い変形の軽減化を図ることを目的とする。 In addition, the receiving work of the central edge portion under the gasket in the stationary mode is shared by the stem annular shoulder portion and the horizontal upper surface of the vertical rib-shaped portion, whereby the radial length of the stem annular shoulder portion is shortened as compared with the case where it is used alone. The purpose is to reduce the copying deformation of this edge portion.

In the operation mode, S1 flows from the container body 7 through the dip tube 6 into the vertical hole portion 2f, passes upward through each L-shaped groove-shaped portion 2e, and goes from the stem hole portion 1c to the stem passage portion 1b. Following this, the powder flow that is ejected from the discharge port on the operation button side to the external space area,
Is shown.

図示の内容物放出機構の特徴は、

(23)縦凹状スペース1hは、ステム環状肩部1dの直下側となる外方下り傾斜のテーパ状底面1jを有する、
ことなどである。
The feature of the illustrated content release mechanism is
(21) In the stationary mode of FIG. 2, the lower central edge portion of the gasket is dispersedly received by the stem annular shoulder portion 1d and the horizontal upper surface 1g of the vertical rib-shaped portion 1f, that is, the lower peripheral circumference of the central opening of the stem gasket 3. The surface 3b abuts on the stem annular shoulder 1d, and the inner end side annular bottom surface 3c abuts on the horizontal upper surface 1g.
(22) The stem 1 has an annular stem annular shoulder portion 1d that spreads downward and has an annular tapered surface.
The powder adhering to the outer peripheral surface of the stem, which is continuously set from the lower end of the annular shoulder to the lower and outer sides and is scraped off by the stem gasket 3 when returning from the operation mode of FIG. 3 to the stationary mode of FIG. 2, falls vertically. With a concave space 1h,
(23) The vertically concave space 1h has a tapered bottom surface 1j having an outward downward inclination, which is directly below the stem annular shoulder portion 1d.
And so on.

図示の内容物放出機構は、このようにステム1の静止モード位置決め用の要素としてステム環状肩部1dのみではなく、その下端から外下側に連続形成された複数の縦リブ状部1fの上端面である水平上面1gも用いている。 The illustrated content release mechanism is not only the stem annular shoulder portion 1d as an element for positioning the stem 1 in a stationary mode, but also above a plurality of vertical rib-shaped portions 1f continuously formed from the lower end to the outer and lower sides thereof. A horizontal upper surface of 1 g, which is an end face, is also used.

この水平上面1gの併用にともない、ステム環状肩部のみでステム1の上下方向の静止モード位置を特定する場合よりも水平上面の径方向長さ分だけ短い径方向幅のステム環状肩部1dを用いえる。 With this combined use of the horizontal upper surface 1g, the stem annular shoulder portion 1d having a radial width shorter than the case where the vertical stationary mode position of the stem 1 is specified only by the stem annular shoulder portion is shortened by the radial length of the horizontal upper surface. Can be used.

すなわち、ステム環状肩部1dと水平上面1gとの全体径方向長さの上面部分がガスケット下中央エッジ部分に当接するので、ステム1は、ステム環状肩部1dの径方向幅を水平上面なしの場合のように長くしなくても、上下方向の静止モード位置へ安定的に保持される。 That is, since the upper surface portion having the overall radial length of the stem annular shoulder portion 1d and the horizontal upper surface 1g abuts on the central edge portion under the gasket, the stem 1 has the radial width of the stem annular shoulder portion 1d without the horizontal upper surface. Even if it is not lengthened as in the case, it is stably held in the stationary mode position in the vertical direction.

このステム環状肩部1dの径方向幅の短縮化にともない、静止モードにおいてステム環状肩部と常時密接するガスケット下中央エッジ部分の径方向外方への倣い変形の程度を抑えることができる。 With the shortening of the radial width of the stem annular shoulder portion 1d, it is possible to suppress the degree of radial outward copying deformation of the lower central edge portion of the gasket that is always in close contact with the stem annular shoulder portion in the stationary mode.

また、外方下り傾斜のステム環状肩部1dの下端部分から外下側に複数の縦リブ状部1fが連続形成され、この隣同士の縦リブ状部間には外方下り傾斜のテーパ状底面1jからなる縦凹状スペース1hが設定されている。 Further, a plurality of vertical rib-shaped portions 1f are continuously formed on the outer lower side from the lower end portion of the stem annular shoulder portion 1d having an outward downward slope, and a tapered shape having an outward downward slope is formed between the adjacent vertical rib-shaped portions. A vertically concave space 1h composed of a bottom surface 1j is set.

このようなステム環状肩部1dから縦凹状スペース1hへと続く下り構成をとることにより、静止モードへの復帰時にガスケット下中央エッジ部分などでかき落とされる直円筒状部1aやステム環状肩部1dの外周面付着パウダーは縦凹状スペース1hへ仮収容される。 By adopting such a descending configuration that continues from the stem annular shoulder portion 1d to the vertically concave space 1h, the linear cylindrical portion 1a and the stem annular shoulder portion 1d that are scraped off by the central edge portion under the gasket when returning to the stationary mode are adopted. The powder adhering to the outer peripheral surface of the above surface is temporarily stored in the vertically concave space 1h.

この縦凹状スペース1hへのパウダー仮収容により、ステム環状肩部1dとステムガスケット3の中央開口下側周面3bとの間にいわば挟みこまれてしまう被かき落しパウダー量が激減する。 By temporarily storing the powder in the vertically concave space 1h, the amount of scraped powder that is sandwiched between the stem annular shoulder portion 1d and the peripheral surface 3b below the central opening of the stem gasket 3 is drastically reduced.

縦凹状スペース1hへ仮収容されたパウダーは概略、この凹状スペースのテーパ状底面1jを下方に移動してその下端部分からハウジング2の内部空間域に落下する。 The powder temporarily stored in the vertically concave space 1h generally moves downward on the tapered bottom surface 1j of the concave space and falls from the lower end portion thereof into the internal space area of the housing 2.

図1のステム1は、概略、その上方から直円筒状部1aと、ステム環状肩部1dと、鐘状部1eとを備えている。 The stem 1 of FIG. 1 roughly includes a straight cylindrical portion 1a, a stem annular shoulder portion 1d, and a bell-shaped portion 1e from above.

鐘状部1eの上端側外周面には、ステム環状肩部1dの下端部分から個々に連続し、全体として環状の計二十個の縦リブ状部1fが形成され、隣同士の縦リブ状部間は縦凹状スペース1hとなっている。 On the outer peripheral surface on the upper end side of the bell-shaped portion 1e, a total of 20 vertical rib-shaped portions 1f that are continuous from the lower end portion of the stem annular shoulder portion 1d and are annular as a whole are formed, and are adjacent to each other in a vertical rib shape. There is a vertically concave space 1h between the parts.

縦凹状スペース1hは、テーパ状底面1jと、これの3辺からそれぞれ起立した形の左右側起立面および起立奥面とを有している。 The vertically concave space 1h has a tapered bottom surface 1j, and left and right upright surfaces and upright back surfaces that are upright from the three sides thereof.

In the stationary mode of FIG.
(31) The stem 1 is urged upward by the elastic force of the coil spring 4, and the stem 1 is urged upward.
(32) The outer peripheral surface on the lower end side of the straight cylindrical portion 1a is in close contact with the peripheral surface 3a on the upper side of the central opening of the stem gasket 3.
(33) The outer peripheral surface of the stem annular shoulder portion 1d is in close contact with the peripheral surface 3b below the central opening of the stem gasket 3.
(34) The horizontal upper surface 1 g of the vertical rib-shaped portion 1f is in close contact with the inner end side annular bottom surface 3c of the stem gasket 3.
(35) The stem passage portion 1b is set so as not to communicate with the internal space area of the housing 2 and the powder of the container body 7 is not discharged to the external space area.

(43)ハウジング2の内面部分に形成されたL字溝状部2eを通りステム孔部1cおよびステム通路部1bを経て外部空間域に噴射される、パウダー流れS1が生じる。
In the operation mode of FIG. 3, that is, in the state where the stem 1 moves downward while resisting the elastic force of the coil spring 4 due to the user's content release operation.
(41) The stem passage portion 1b communicates with the internal space area of the housing 2 via the stem hole portion 1c.
(42) The horizontal upper surface 1 g of the vertical rib-shaped portion 1f is separated downward from the annular exposed lower surface of the stem gasket 3.
(43) A powder flow S1 is generated, which is injected into the external space area through the L-shaped groove-shaped portion 2e formed on the inner surface portion of the housing 2 and the stem hole portion 1c and the stem passage portion 1b.

内容物放出操作の終了にともない、ステム1は、コイルスプリング4の作用により上動して直円筒状部1a,ステム環状肩部1dおよび水平上面1gがそれぞれ中央開口上側周面3a,中央開口下側周面3bおよび内端側環状底面3cに密接した状態で停止する。 Upon completion of the content release operation, the stem 1 moves upward by the action of the coil spring 4, and the linear cylindrical portion 1a, the stem annular shoulder portion 1d, and the horizontal upper surface 1g are respectively centered on the upper peripheral surface 3a and below the central opening. It stops in close contact with the side peripheral surface 3b and the inner end side annular bottom surface 3c.

すなわち直円筒状部1aより大径相当部分のステム環状肩部1dおよび水平上面1gを持つステム1は、ステムガスケット3から決して抜けることのない状態で静止モードに復帰する。 That is, the stem 1 having the stem annular shoulder portion 1d and the horizontal upper surface 1g of the portion corresponding to the diameter larger than the linear cylindrical portion 1a returns to the stationary mode in a state where the stem gasket 3 never comes off.

本発明が、図示の実施形態に限定されないことは勿論であって例えば、

It goes without saying that the present invention is not limited to the illustrated embodiment, for example.
The arrangement relationship between the stem hole 1c and the stem gasket 3 is set so that the inflow side opening of the stem hole is closed by the stem gasket 3 in the stationary mode of FIG.
