次に、本実施例の噴出容器の使用態様と、作用効果について説明する。
噴出容器の組立は、まず、係合キャップＣ２の内筒２１内に上方より押下げキャップＣ１の係合筒１６を挿入し、内筒２１の係合溝部２６に係合筒１６の外周に配設した係合突部１９を係合させるとともに、押下げキャップＣ１の頂壁１５周縁の嵌合リング１５ａと係合キャップＣ２の上壁２０上面の嵌合リング２０ａを係合させて、押下げキャップＣ１を係合キャップＣ２に装着したオーバーキャップＣを形成する。 Next, the usage mode and operational effects of the ejection container of the present embodiment will be described.
For assembly of the ejection container, first, the engaging cylinder 16 of the push-down cap C1 is inserted into the inner cylinder 21 of the engaging cap C2 from above, and is arranged on the outer periphery of the engaging cylinder 16 in the engaging groove portion 26 of the inner cylinder 21. The engaging projection 19 provided is engaged, and the fitting ring 15a on the periphery of the top wall 15 of the push-down cap C1 is engaged with the fitting ring 20a on the upper surface of the upper wall 20 of the engagement cap C2 to push down. An overcap C in which the cap C1 is attached to the engagement cap C2 is formed.

次に、ステム５に噴出ヘッドＢを装着したエアゾール容器Ａの上方にオーバーキャップＣを被せ、エアゾール容器Ａのマウンテンカップ３の係合環４に係合キャップＣ２の内筒２１の下部筒２５下端の係合突部２７を係合させることで、エアゾール容器Ａの上部にオーバーキャップＣを装着し、閉蓋した噴出容器を得ることができる。 Next, an overcap C is placed over the aerosol container A with the ejection head B mounted on the stem 5, and the lower end of the lower cylinder 25 of the inner cylinder 21 of the engagement cap C2 is placed on the engagement ring 4 of the mountain cup 3 of the aerosol container A. By engaging the engaging protrusions 27, the overcap C can be attached to the upper part of the aerosol container A, and the ejection container closed can be obtained.

噴出容器の使用にあたっては、係合キャップＣ２の外筒２２を把持してオーバーキャップＣをエアゾール容器Ａから上方に引張って開蓋し、噴出ヘッドＢを押下げ操作すると、内容物を噴出孔１１から噴出させることができる。 When the ejection container is used, when the outer cap 22 of the engagement cap C2 is gripped, the overcap C is pulled upward from the aerosol container A to open the lid, and the ejection head B is pushed down, the contents are ejected from the ejection hole 11. Can be ejected from.

内容物を全て使用し、エアゾール容器Ａを廃棄する際には、エアゾール容器Ａ内の残留ガスの抜き取りを行う。
残留ガスの抜き取りは、まず、オーバーキャップＣをエアゾール容器Ａから取外し、押下げキャップＣ１の内方の指掛片１７に指などを掛け、係合キャップＣ２に対し押下げキャップＣ１を廻動させる。 When all the contents are used and the aerosol container A is discarded, the residual gas in the aerosol container A is extracted.
In order to extract the residual gas, first, the overcap C is removed from the aerosol container A, a finger or the like is put on the inner finger-holding piece 17 of the push-down cap C1, and the push-down cap C1 is rotated with respect to the engagement cap C2. .

廻動させることで、図３（ｂ）に示すように、押下げキャップＣ１の係合筒１６に配設した係合突部１９と係合キャップＣ２の内筒２１の係合溝部２６の係合が外れるとともに、係合突部１９の側周が内筒２１の上部筒２３内周面に当接して、内筒２１は一部を変形させられる。 By rotating, as shown in FIG. 3B, the engagement protrusion 19 disposed on the engagement cylinder 16 of the push-down cap C1 and the engagement groove 26 of the inner cylinder 21 of the engagement cap C2 are engaged. As the engagement is disengaged, the side periphery of the engaging projection 19 abuts against the inner peripheral surface of the upper cylinder 23 of the inner cylinder 21, and the inner cylinder 21 is partially deformed.

係合キャップＣ２の内筒２１の一部を変形したまま、押下げキャップＣ１を下方から押し上げると、係合キャップＣ２の内筒２１内から押下げキャップＣ１が上方に摺動し、最後は外れる。 If the push-down cap C1 is pushed up from below while part of the inner cylinder 21 of the engagement cap C2 is deformed, the push-down cap C1 slides upward from the inner cylinder 21 of the engagement cap C2, and finally comes off. .

次に、押下げキャップＣ１を直接エアゾール容器Ａの上方に被せ、エアゾール容器Ａのマウンテンカップ３の係合環４外周に押下げキャップＣ１の係合筒１６の嵌合突部１８を係合させて装着し、閉蓋する。 Next, the pressing cap C1 is directly placed over the aerosol container A, and the fitting protrusion 18 of the engaging cylinder 16 of the pressing cap C1 is engaged with the outer periphery of the engagement ring 4 of the mountain cup 3 of the aerosol container A. Install and close.

エアゾール容器Ａの上部に押下げキャップＣ１を装着すると、図４に示すように、押下げキャップＣ１の頂壁１５の下面が噴出ヘッドＢの頂壁１０上面に当接し、噴出ヘッドＢを一定の位置まで押下げ、残留ガスの抜き取りが行われる。
残留ガスは、噴出ヘッドＢの噴出孔１１から押下げキャップＣ１内に噴出され、押下げキャップＣ１に設けた空気の流路を通り、エアゾール容器Ａ外に排出される。 When the pressing cap C1 is attached to the upper part of the aerosol container A, the lower surface of the top wall 15 of the pressing cap C1 comes into contact with the upper surface of the top wall 10 of the ejection head B, as shown in FIG. The gas is pushed down to the position and the residual gas is extracted.
The residual gas is ejected from the ejection hole 11 of the ejection head B into the push-down cap C1, passes through the air flow path provided in the push-down cap C1, and is discharged out of the aerosol container A.

押下げキャップＣ１の係合筒１６の嵌合突部１８と、エアゾール容器Ａのマウンテンカップ３の係合環４との係合が維持され、そのまま放置するだけで、ガスの抜き取りが継続され、エアゾール容器Ａ内の残留ガスや内容物は完全に抜き取られ、エアゾール容器Ａを安全に廃棄することができる。
また、エアゾール容器Ａ内の残留ガスや内容物を完全に抜き取り後、エアゾール容器Ａから押下げキャップＣ１を取外し、分別廃棄することもできる。 The engagement between the engagement protrusion 18 of the engagement cylinder 16 of the push-down cap C1 and the engagement ring 4 of the mountain cup 3 of the aerosol container A is maintained. Residual gas and contents in the aerosol container A are completely extracted, and the aerosol container A can be safely discarded.
In addition, after the residual gas and contents in the aerosol container A are completely extracted, the push-down cap C1 can be removed from the aerosol container A and discarded separately.

上記実施例では、係合キャップＣ２の内筒２１の内周下端に設けた係合突部２７と、エアゾール容器Ａのマウンテンカップ３の係合環４外周とを係合させて、エアゾール容器Ａの上部にオーバーキャップＣを装着して閉蓋したが、変形実施例として、図５に示すように、エアゾール容器Ａの肩部２の外縁に係合部２ａを設け、係合キャップＣ２の外筒２２の内周下端に肩部２の外縁に設けた係合部２ａに係合する係合突条２２ａを設けて、エアゾール容器Ａの上部にオーバーキャップＣを装着し、閉蓋するように係合キャップＣ２を形成してもよい。 In the above-described embodiment, the engagement protrusion 27 provided at the lower end of the inner periphery of the inner cylinder 21 of the engagement cap C2 is engaged with the outer periphery of the engagement ring 4 of the mountain cup 3 of the aerosol container A. As shown in FIG. 5, as an alternative embodiment, an engagement portion 2a is provided on the outer edge of the shoulder portion 2 of the aerosol container A, and the outer cap C2 is placed outside the engagement cap C2. An engagement protrusion 22a that engages with an engagement portion 2a provided at the outer edge of the shoulder portion 2 is provided at the lower end of the inner periphery of the cylinder 22, and an overcap C is attached to the upper portion of the aerosol container A so as to close the lid. An engagement cap C2 may be formed.

係合キャップＣ２の外筒２２の内周下端に係合突条２２ａを設ける場合には、内筒２１の下部筒２５は必要としないので、係合キャップＣ２の成形が簡単なものとなる。
オーバーキャップの係合キャップをエアゾール容器に装着させる構成は、上記実施例の形態に限定されない。 When the engagement protrusion 22a is provided at the inner peripheral lower end of the outer cylinder 22 of the engagement cap C2, the lower cylinder 25 of the inner cylinder 21 is not required, so that the engagement cap C2 can be easily formed.
The configuration in which the engagement cap of the overcap is attached to the aerosol container is not limited to the embodiment described above.

本発明は、押下げキャップと係合キャップとからなるオーバーキャップの押下げキャップを係合キャップに対して回転させることで取外し、押下げキャップのみをエアゾール容器の上部に装着することで残留ガスの抜き取りができるので、種々のエアゾール容器のガス抜き機構として広く利用できる。 The present invention removes the push-down cap of the overcap consisting of the push-down cap and the engagement cap by rotating it with respect to the engagement cap, and attaches only the push-down cap to the upper part of the aerosol container to remove residual gas. Since it can be extracted, it can be widely used as a degassing mechanism for various aerosol containers.
