本発明は、エアゾール容器に残留する圧縮ガスを排出する機能を兼ね備えたエアゾール容器用オーバーキャップに関するものである。   The present invention relates to an overcap for an aerosol container having a function of discharging compressed gas remaining in the aerosol container.

エアゾール容器内の残留ガスを抜くための従来の手段としては、エアゾール容器の肩部に装着した肩カバーと一体に係止片を設け、この係止片を押圧ヘッドの上部に乗り上げる位置まで塑性変形させることにより、押圧ヘッドの下向き状態を維持するものがある（例えば、特許文献１参照。）。
特開２００２−６８３３９号公報 As a conventional means for removing residual gas in the aerosol container, a locking piece is provided integrally with a shoulder cover attached to the shoulder portion of the aerosol container, and plastic deformation is performed up to the position where the locking piece rides on the upper part of the pressing head. By doing so, there is one that maintains the downward state of the pressing head (see, for example, Patent Document 1).
JP 2002-68339 A

しかしながら、かかる従来手段では、使用者が手を使って直接係止片を押圧ヘッドに向けて塑性変形させなければならないため、指等が押圧ヘッドの噴射口に触れて手が汚れてしまう可能性がある。このため、手を汚さないでガス抜きを行うためには、相応の注意を払わなければならないため、ガス抜きを行うに至るまで操作が煩雑である。   However, in such conventional means, since the user must use the hand to plastically deform the locking piece directly toward the pressing head, there is a possibility that a finger or the like touches the ejection port of the pressing head and the hand becomes dirty. There is. For this reason, in order to vent the gas without polluting the hands, appropriate care must be taken, and the operation is complicated until the venting is performed.

本発明が解決しようとする課題は、ガス抜きを行う際に手が汚れることと、それによりガス抜きを行うための操作が煩雑になることである。   The problem to be solved by the present invention is that the hands get dirty when degassing, and the operation for degassing becomes complicated.

本発明は、エアゾール容器の押圧ヘッドを格納するエアゾール容器用オーバーキャップであって、前記オーバーキャップは、押圧ヘッドを露出させる貫通孔を有し、エアゾール容器に着脱可能に係止されるベースと、このベースに着脱可能に保持され、ベースと協働してその内側に押圧ヘッドを収納するキャップ本体からなり、前記ベースに、オーバーキャップを最初に装着する際、エアゾール容器に形成された前記ベースとの係合部に接触して押圧ヘッドに向かって塑性変形し、その先端部分が、オーバーキャップを取り外して再度装着を行う時に、押圧ヘッドの外周壁に設けた環状のリブに当接して当該押圧ヘッドを押し下げる舌片を設けたことを特徴とするものである。
The present invention is an aerosol container overcap for storing a pressing head of an aerosol container, wherein the overcap has a through hole that exposes the pressing head and is detachably locked to the aerosol container; A cap body that is detachably held by the base and accommodates a pressing head inside the base in cooperation with the base. When the overcap is first attached to the base, When the overcap is removed and reattached, the tip part abuts against the annular rib provided on the outer peripheral wall of the pressure head and presses against the pressure head. A tongue piece for pushing down the head is provided.

本発明によれば、製品出荷時にオーバーキャップを取り付けるだけでガス抜きの準備が完了し、オーバーキャップを取り外して再度装着すれば、そのまま押圧ヘッドを押し下げることができる。従って、使用者は手を汚すことなく、オーバーキャップを着脱するだけの簡単な作業でガス抜きをすることができる。   According to the present invention, preparation for degassing is completed simply by attaching an overcap at the time of product shipment, and if the overcap is removed and attached again, the pressing head can be pushed down as it is. Therefore, the user can degas by a simple operation of simply attaching and detaching the overcap without getting his hands dirty.

以下、図面を参照して、本発明の一形態を詳細に説明する。   Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

符号1は、内容物と共に圧縮ガスが充填されたエアゾール容器である。エアゾール容器1は、その肩部1aに環状のマウントカップ2が取り付けられており、マウントカップ2の取り付け部分が環状の巻き締め部となり、この巻き締め部が係合部2aを構成する。係合部2aに取り囲まれた部分には、エアゾール用容器内の図示せぬバルブに繋がるステム3が露出している。   Reference numeral 1 denotes an aerosol container filled with compressed gas together with the contents. The aerosol container 1 has an annular mount cup 2 attached to a shoulder portion 1a thereof, and an attachment portion of the mount cup 2 serves as an annular winding portion, and this winding portion constitutes an engaging portion 2a. A stem 3 connected to a valve (not shown) in the aerosol container is exposed at a portion surrounded by the engaging portion 2a.

ステム3は、エアゾール容器の長手方向軸線に沿って上下動可能で、その先端には、ステム3を経てエアゾール容器1内に通じる押圧ヘッド4が取り付けられている。これにより、使用者が押圧ヘッド4を押し下げると、押圧ヘッド4の噴射口4aから圧縮ガスと共に内容物が噴射される。また、押圧ヘッド4の外周壁には、その周方向に沿って延在し外向きに突出する環状のリブ4bが設けられている。   The stem 3 can be moved up and down along the longitudinal axis of the aerosol container, and a pressing head 4 that leads to the inside of the aerosol container 1 through the stem 3 is attached to the tip of the stem 3. Thus, when the user pushes down the pressing head 4, the contents are injected together with the compressed gas from the injection port 4a of the pressing head 4. Further, an annular rib 4b extending along the circumferential direction and projecting outward is provided on the outer peripheral wall of the pressing head 4.

符号5は、押圧ヘッド4を環状のマウントカップ2と共に格納するエアゾール容器用オーバーキャップである。符号51は、エアゾール容器1の肩部1aを取り囲む周壁52と、この周壁52に繋がり押圧ヘッド4を露出させる貫通孔53を有する仕切壁54とを備えるベースである。ベース51は、塑性変形可能な合成樹脂からなる。   Reference numeral 5 denotes an aerosol container overcap for storing the pressing head 4 together with the annular mount cup 2. Reference numeral 51 denotes a base including a peripheral wall 52 that surrounds the shoulder portion 1a of the aerosol container 1 and a partition wall 54 that is connected to the peripheral wall 52 and has a through hole 53 that exposes the pressing head 4. The base 51 is made of a plastic resin that can be plastically deformed.

仕切壁54には、その裏面から貫通孔53に沿って環状に垂下してなり、その先端部分55aが、係合部2aの外側に着脱可能に係止される環状の係止部55を一体に設けられている。これにより、ベース51は、エアゾール容器1の肩カバーとして着脱可能に装着される。なお、係止部55は、着脱操作における適切な嵌合強度を付与することから、環状の係合部2aに沿って間欠に設けたり、先端部分55aの肉厚を調整する等といった手段を適用することもできる。   The partition wall 54 has an annular locking portion 55 that is suspended from the rear surface along the through-hole 53 in an annular shape, and whose tip portion 55a is detachably locked to the outside of the engaging portion 2a. Is provided. Thereby, the base 51 is detachably mounted as a shoulder cover of the aerosol container 1. Note that the locking portion 55 provides appropriate fitting strength in the attaching / detaching operation, so that means such as intermittent provision along the annular engaging portion 2a or adjustment of the thickness of the tip portion 55a are applied. You can also

また、仕切壁54には、貫通孔53と環状の係止部55との間に、その裏面から垂下してなる３つの舌片56が一体に設けられている。３つの舌片56はそれぞれ、ベース51をエアゾール容器1に装着する際、その先端部分56aが、係合部2aに接触して押圧ヘッド4に向かって内側に滑動する位置に配置される。これにより、ベース51をエアゾール容器1に装着すれば、各舌片56は、その先端部分56が内側に塑性変形する。   The partition wall 54 is integrally provided with three tongue pieces 56 that are suspended from the back surface between the through hole 53 and the annular locking portion 55. Each of the three tongue pieces 56 is disposed at a position where the tip end portion 56a contacts the engaging portion 2a and slides inward toward the pressing head 4 when the base 51 is attached to the aerosol container 1. Thus, when the base 51 is mounted on the aerosol container 1, the tip portions 56 of the respective tongue pieces 56 are plastically deformed inward.

符号57は、ベース51に着脱可能に保持され、ベース51と協働してその内側に押圧ヘッド4を収納するキャップ本体である。このキャップ本体57は、ベース51の周壁52に形成された環状の段差部分52aに圧入嵌合によって着脱可能に保持される周壁57aと、この周壁57aと一体に繋がる天壁57bとからなる円筒形状である。なお、ベース51の外観形状は、円筒形状に限らず、ドーム形状等であってもよい。   Reference numeral 57 denotes a cap body that is detachably held on the base 51 and accommodates the pressing head 4 inside thereof in cooperation with the base 51. The cap body 57 has a cylindrical shape including a peripheral wall 57a that is detachably held by press-fitting to an annular stepped portion 52a formed on the peripheral wall 52 of the base 51, and a ceiling wall 57b that is integrally connected to the peripheral wall 57a. It is. The appearance of the base 51 is not limited to a cylindrical shape, and may be a dome shape or the like.

次に、図１〜４を参照して、本発明の作用を説明する。   Next, the operation of the present invention will be described with reference to FIGS.

先ず、製品出荷時には、エアゾール容器1の肩部1aにオーバーキャップ5が装着されている。このとき、ベース51の舌片56は、図２に示すように、その先端部分56aが係合部2aに接触して押圧ヘッド4に向かって内側に塑性変形する。これにより、使用者は、自らの手を汚すことなく、オーバーキャップ5を装着することができる。   First, an overcap 5 is attached to the shoulder 1a of the aerosol container 1 at the time of product shipment. At this time, the tongue piece 56 of the base 51 is plastically deformed inward toward the pressing head 4 with its tip end portion 56a contacting the engaging portion 2a as shown in FIG. Thereby, the user can put on the overcap 5 without getting his hands dirty.

内容物を噴射させる場合は、ベース51からキャップ本体57を取り外してベース51をエアゾール容器の肩カバーとして用いながら、押圧ヘッド4を操作して、圧縮ガスと共に内容物を噴射口4aから噴射させる。   When injecting the contents, the cap main body 57 is removed from the base 51 and the press head 4 is operated while using the base 51 as a shoulder cover of the aerosol container to inject the contents from the injection port 4a together with the compressed gas.

エアゾール容器1を廃棄する場合は、先ず、図３に示したように、一度オーバーキャップ5をエアゾール容器1から取り外す。このとき、各舌片56の先端部分56aは、押圧ヘッド4に設けたリブ4bの下側に潜り込むように形成されているため、リブ4bに引っ掛かることなく、同図に示すように、押圧ヘッド4に向かって塑性変形した状態を維持している。   When discarding the aerosol container 1, first, as shown in FIG. 3, the overcap 5 is once removed from the aerosol container 1. At this time, since the tip portion 56a of each tongue piece 56 is formed so as to sink under the rib 4b provided in the pressing head 4, as shown in FIG. The plastic deformation state toward 4 is maintained.

次に、オーバーキャップ5を再度、エアゾール容器1に装着する。このとき、舌片56の先端部分56aは、押圧ヘッド4のリブ4bに当接して押圧ヘッド4を押し下げ、係止部55によりエアゾール容器1の肩部1aに係止されると、押圧ヘッド4の押し下げ状態を維持し、残留した圧縮ガスを収納空間Ｒ内に噴射させる。これにより、使用者は、自らの手を汚すことなく、エアゾール容器のガス抜きを行うことができる。   Next, the overcap 5 is attached to the aerosol container 1 again. At this time, the tip portion 56a of the tongue piece 56 abuts against the rib 4b of the pressing head 4 to push down the pressing head 4, and when the locking portion 55 is locked to the shoulder 1a of the aerosol container 1, the pressing head 4 Is maintained, and the remaining compressed gas is injected into the storage space R. Thereby, the user can degas the aerosol container without getting his hands dirty.

なお、舌片56は、貫通孔53に沿って均等な間隔で少なくとも３つ配置すれば、押圧ヘッド4を安定した状態で押し下げることができるが、舌片56の全長を変更してその先端部分56aの塑性変形量を変更させれば、少なくとも１つであってもよい。   If at least three tongue pieces 56 are arranged at equal intervals along the through-hole 53, the pressing head 4 can be pushed down in a stable state. If the amount of plastic deformation of 56a is changed, at least one may be sufficient.

収納空間Ｒ内に噴射される圧縮ガスは、キャップ本体57を取り外すことなく、図４に矢示するように、キャップ本体57の周壁57aとベース51の周壁52との間の隙間や、ベース51の周壁52とエアゾール容器1の肩部1aとの間の隙間から逃がせるが、ガス量が多い場合等では、ベース51からキャップ本体57を取り外したり、別途ガス抜き孔、溝等を設けてもよい。   The compressed gas injected into the storage space R is not removed from the cap body 57, as shown by the arrows in FIG. 4, and the gap between the peripheral wall 57a of the cap body 57 and the peripheral wall 52 of the base 51, the base 51 Can be escaped from the gap between the peripheral wall 52 and the shoulder 1a of the aerosol container 1, but when the amount of gas is large, the cap body 57 can be removed from the base 51, or a separate vent hole, groove, etc. Good.

本発明によれば、製品出荷時にオーバーキャップ5を取り付けるだけでガス抜きの準備が完了し、オーバーキャップ5を取り外して再度装着すれば、そのまま押圧ヘッド4を押し下げることができる。従って、使用者は手を汚すことなく、オーバーキャップ5を着脱するだけの簡単な作業でガス抜きをすることができる。   According to the present invention, preparation for degassing is completed simply by attaching the overcap 5 at the time of product shipment. If the overcap 5 is removed and attached again, the pressing head 4 can be pushed down as it is. Therefore, the user can degas by a simple operation of simply attaching and detaching the overcap 5 without getting his hands dirty.

また、ベース51は、マウントカップ2の係合部2aに着脱可能に係止されるものであるが、ベース51をエアゾール容器1に着脱可能に装着方法はこれによらない。但し、係止部55を係合部2a外側に係止させることにより、ベース51の着脱が可能となるのであれば、エアゾール容器1の外観形状に変更を加える必要がないため、既存のエアゾール容器1に使用できて汎用性が高い。   The base 51 is detachably locked to the engaging portion 2a of the mount cup 2. However, the mounting method is irrelevant so that the base 51 can be detachably attached to the aerosol container 1. However, if the base 51 can be attached and detached by locking the locking portion 55 to the outside of the engaging portion 2a, there is no need to change the external shape of the aerosol container 1, so that the existing aerosol container It can be used for 1 and is highly versatile.

キャップ本体57は、ベース51の周壁52に圧入装着されているが、凹凸によるアンダーカット嵌合や螺合等であってよい。   The cap body 57 is press-fitted to the peripheral wall 52 of the base 51, but may be undercut fitting or screwing due to unevenness.

上述したところは、本発明の好適な形態であるが、請求の範囲内で様々な変更を加えることができる。例えば、ベース51は、ガス抜きするために単独で使用することも可能である。押圧ヘッド4の形態は、上述したような押しボタンタイプに限らず、噴射口4aがエアゾール容器の長手方向軸線に並行に取り付けられるスパウトタイプであってもよい。従って、内容物の噴射形態も、霧状・泡状等を問わない。   The above is a preferred embodiment of the present invention, but various modifications can be made within the scope of the claims. For example, the base 51 can be used alone for venting. The form of the pressing head 4 is not limited to the push button type as described above, but may be a spout type in which the injection port 4a is attached in parallel to the longitudinal axis of the aerosol container. Therefore, the injection form of the contents may be mist or foam.
