しかしながら、前記従来のエアゾール容器用オーバーキャップでは、例えばオーバーキャップ付きエアゾール容器の流通過程や、需要者が内容物を使用するのにオーバーキャップをエアゾール容器に対して繰り返し着脱する等の残留ガスを抜き出す前に、押圧板に作用する外力によって、不用意に前記弱化部が破断するおそれがあった。
また、天板部に形成された前記弱化部がオーバーキャップの見映えを悪くするおそれもあった。 However, in the conventional overcap for an aerosol container, for example, the distribution process of the aerosol container with an overcap or the residual gas such as repeatedly attaching and detaching the overcap to the aerosol container when a consumer uses the contents is extracted. Previously, the weakened portion may be inadvertently broken by an external force acting on the pressing plate.
In addition, the weakened portion formed on the top plate portion may deteriorate the appearance of the overcap.

本発明は、このような事情を考慮してなされたもので、天板部に押圧板を連結する弱化部が、残留ガスを抜き出す前に不用意に破断するのを防ぐことができるとともに、外観に優れたエアゾール容器用オーバーキャップおよびオーバーキャップ付きエアゾール容器を提供することを目的とする。 The present invention has been made in consideration of such circumstances, and the weakened portion connecting the pressing plate to the top plate portion can be prevented from being carelessly broken before extracting the residual gas, and has an external appearance. It is an object of the present invention to provide an overcap for an aerosol container and an aerosol container with an overcap excellent in the above.

上記課題を解決して、このような目的を達成するために、本発明のエアゾール容器用オーバーキャップは、上方付勢状態で立設されたステムと、このステムに取り付けられた噴霧ヘッドと、を備えたエアゾール容器に着脱可能に装着されるエアゾール容器用オーバーキャップであって、エアゾール容器に装着した状態で前記噴霧ヘッドの上面に対向する天板部が備えられ、この天板部に押圧板が区画されるとともに、この押圧板の外周縁は破断可能な弱化部を介して前記天板部に連結され、前記押圧板は、前記弱化部を破断して押圧板の押下端部をこのオーバーキャップの内部に進入させたときに、このオーバーキャップをエアゾール容器に装着した状態で、前記押下端部がステムを押し下げる残留ガス抜き姿勢に保持される構成とされ、前記天板部の表面に、前記押圧板および弱化部を覆う蓋部材が取り外し可能に設けられ、前記天板部に、前記蓋部材の外周面をその径方向外方から囲繞する囲繞筒部が立設されるとともに、この囲繞筒部に前記蓋部材を係止する係止部が設けられ、このオーバーキャップをエアゾール容器から外した状態で、前記押圧板を、前記天板部の裏面側から前記弱化部を破断しつつ押し上げたときに、前記蓋部材がこの押圧板により押し上げられ前記係止部から外れる構成とされたことを特徴とする。
この発明によれば、天板部の表面に前記蓋部材が設けられているので、例えばオーバーキャップ付きエアゾール容器の流通過程や、需要者が内容物を使用するのにオーバーキャップをエアゾール容器に対して繰り返し着脱する等の残留ガスを抜き出す前に、押圧板の表面側に外力が作用しても、この外力を蓋部材で受け止めて、この力が弱化部に作用するのを防ぐことが可能になり、この弱化部が不用意に破断するのを防止することができる。
さらに、前記弱化部が蓋部材で覆われているので、天板部に弱化部が形成されたことによりこのオーバーキャップの見映えが悪くなるのを防ぐことが可能になり、外観に優れたオーバーキャップを提供することができる。
しかも、この蓋部材は、天板部の表面に取り外し可能に設けられているので、残留ガスを抜き出すときには蓋部材を天板部から取り外すことが可能になり、このオーバーキャップに優れた操作性を具備させることができる。
そして、蓋部材の外周面がその径方向外方から囲繞筒部の内周面により囲繞されるとともに、この蓋部材が前記係止部で係止されているので、残留ガスを抜き出す前に蓋部材の外周側に外力が作用しても、この外力を囲繞筒部で受け止めることが可能になり、この蓋部材が天板部に対して移動させられ天板部から外れるのを防ぐことができる。なお、残留ガスを抜き出す前に蓋部材の表面側に外力が作用しても、この蓋部材は天板部の表面に当接しているので移動しない。 In order to solve the above problems and achieve such an object, an overcap for an aerosol container of the present invention comprises a stem erected in an upward biased state, and a spray head attached to the stem. An aerosol container overcap that is detachably attached to the provided aerosol container, and is provided with a top plate portion facing the top surface of the spray head in a state of being attached to the aerosol container, and a pressing plate is provided on the top plate portion. In addition, the outer peripheral edge of the pressing plate is connected to the top plate portion via a breakable weakening portion, and the pressing plate breaks the weakening portion so that the pressing end of the pressing plate is covered with the overcap. When the inside of the container is inserted into the aerosol container, the pressing end is held in a residual gas venting posture that pushes down the stem with the overcap attached to the aerosol container. A lid member that covers the pressing plate and the weakened portion is detachably provided on the surface of the top plate portion, and a surrounding cylinder portion that surrounds the outer peripheral surface of the lid member from the outside in the radial direction stands on the top plate portion. And a locking portion for locking the lid member is provided on the surrounding cylinder portion, and the pressure plate is removed from the back side of the top plate portion with the overcap removed from the aerosol container. When the weakened portion is pushed up while being broken, the lid member is pushed up by the pressing plate and is disengaged from the locking portion.
According to this invention, since the lid member is provided on the surface of the top plate portion, for example, the distribution process of the aerosol container with an overcap, or the overcap with respect to the aerosol container for the consumer to use the contents. Even if an external force acts on the surface side of the pressing plate before extracting the residual gas, such as repeatedly attaching and detaching, it is possible to receive this external force with the lid member and prevent this force from acting on the weakened part Thus, the weakened portion can be prevented from being carelessly broken.
Furthermore, since the weakened portion is covered with a lid member, it is possible to prevent the appearance of the overcap from being deteriorated due to the formation of the weakened portion on the top plate portion, and it is possible to prevent the overcaping having an excellent appearance. A cap can be provided.
In addition, since the lid member is detachably provided on the surface of the top plate portion, the lid member can be removed from the top plate portion when extracting the residual gas, and the overcap has excellent operability. Can be provided.
And since the outer peripheral surface of the lid member is surrounded by the inner peripheral surface of the surrounding tube portion from the outside in the radial direction, and this lid member is locked by the locking portion, the lid is removed before the residual gas is extracted. Even if an external force acts on the outer peripheral side of the member, the external force can be received by the surrounding cylinder portion, and the lid member can be prevented from being moved with respect to the top plate portion and coming off from the top plate portion. . Even if an external force acts on the surface side of the lid member before extracting the residual gas, the lid member does not move because it is in contact with the surface of the top plate portion.

ここで、前述した囲繞筒部および係止部に代えて、互いに係合可能な第１、第２係合部のうち、一方が前記天板部の表面に設けられるとともに、他方が前記蓋部材の裏面に設けられ、第１係合部は、幅広孔と幅狭孔とがそれぞれの幅方向と直交する長手方向に連結された長穴形状の係合孔とされ、第２係合部は、前記天板部の表面、若しくは前記蓋部材の裏面に突設された係合凸部とされるとともに、この係合凸部は、前記天板部の表面、若しくは前記蓋部材の裏面に連結された薄肉部と、この薄肉部の先端に連結された厚肉部とを備え、前記第１係合部の幅広孔に前記第２係合部を挿入した状態で、この第２係合部を、第１係合部の幅狭孔内に向けて相対的にスライド移動させ、前記厚肉部の薄肉部側の端部を、蓋部材の表面、若しくは天板部の裏面における前記幅狭孔の開口周縁部に引っ掛けることによって、第１、第２係合部が互いに係合する構成とされてもよい。
この場合、蓋部材を天板部の表面に取り外し可能に設ける構成を容易かつ確実に実現することができる。 Here, instead of the aforementioned surrounding cylinder part and the locking part, one of the first and second engaging parts that can be engaged with each other is provided on the surface of the top plate part, and the other is the lid member. The first engagement portion is an elongated hole-shaped engagement hole in which a wide hole and a narrow hole are connected in a longitudinal direction perpendicular to the respective width directions, and the second engagement portion is The engaging projection is provided on the front surface of the top plate portion or the back surface of the lid member, and the engaging convex portion is connected to the front surface of the top plate portion or the back surface of the lid member. The second engaging portion in a state in which the second engaging portion is inserted into the wide hole of the first engaging portion, and the thin engaging portion is connected to the tip of the thin portion. Is relatively slid toward the narrow hole of the first engaging portion, and the end of the thick portion on the thin portion side is moved to the surface of the lid member or the ceiling. By hooking the opening edge of the narrow hole in the rear surface parts, the first, it may be configured to the second engagement portion are engaged with each other.
In this case, a configuration in which the lid member is detachably provided on the surface of the top plate portion can be easily and reliably realized.

また、前記第１係合部の幅狭孔の内面には係止凸部が突設され、蓋部材が天板部に取り付けられた状態で、第２係合部の薄肉部は、前記係止凸部と、前記幅狭孔において前記長手方向における幅広孔と反対側の先端との間に挟持されてもよい。
この場合、天板部に取り付けられた蓋部材に、第２係合部を第１係合部の幅広孔側に向けてスライド移動させようとする外力が不意に作用しても、前記係止凸部に第２係合部の薄肉部が引っ掛かることにより、蓋部材がこのようにスライド移動するのを防ぐことができる。したがって、残留ガスを抜き出す前に不用意に蓋部材が天板部から外れるのを防ぐことが可能になり、前述の作用効果が確実に奏功されることになる。 In addition, a locking projection protrudes from the inner surface of the narrow hole of the first engagement portion, and the thin portion of the second engagement portion is in the state where the lid member is attached to the top plate portion. It may be clamped between a stop convex part and the front-end | tip on the opposite side to the wide hole in the said longitudinal direction in the said narrow hole.
In this case, even if an external force that slides the second engaging portion toward the wide hole side of the first engaging portion acts on the lid member attached to the top plate portion unexpectedly, the locking is performed. Since the thin portion of the second engaging portion is caught by the convex portion, it is possible to prevent the lid member from sliding in this way. Therefore, it is possible to prevent the lid member from being inadvertently detached from the top plate portion before extracting the residual gas, and the above-described effects can be reliably achieved.

また、本発明のオーバーキャップ付きエアゾール容器は、上方付勢状態で立設されたステム、およびこのステムに取り付けられた噴霧ヘッドを備えたエアゾール容器と、前記ステムおよび噴霧ヘッドを囲うようにこのエアゾール容器に装着されたエアゾール容器用オーバーキャップとを備えたオーバーキャップ付きエアゾール容器であって、前記エアゾール容器用オーバーキャップが、本発明のエアゾール容器用オーバーキャップであることを特徴とする。 An aerosol container with an overcap according to the present invention includes an aerosol container having a stem erected in an upwardly biased state and a spray head attached to the stem, and the aerosol so as to surround the stem and the spray head.

以下、図面を参照し、この発明の実施の形態について説明する。この実施形態に係るエアゾール容器用オーバーキャップ（以下、「オーバーキャップ」という）１０が装着されるエアゾール容器２０は、上端面に上方付勢状態でステム２２が立設されたエアゾール容器本体と、ステム２２が嵌合された導入口を有する噴霧ヘッド２３と、を備えている。また、エアゾール容器本体は、胴部２４と、この胴部２４の上端に設けられた肩部２５と、を備える容器本体の上端開口部にマウンティングカップ２６が巻き締められ、このマウンティングカップ２６の上面に前記ステム２２が上方付勢状態で立設されている。 Embodiments of the present invention will be described below with reference to the drawings. An aerosol container 20 to which an aerosol container overcap (hereinafter referred to as “overcap”) 10 according to this embodiment is attached includes an aerosol container body in which a stem 22 is erected on an upper end surface in an upward biased state, and a stem. And a spray head 23 having an introduction port with which 22 is fitted. In addition, the aerosol container body has a mounting cup 26 wound around an upper end opening of the container body including a body portion 24 and a shoulder portion 25 provided at the upper end of the body portion 24, and an upper surface of the mounting cup 26. The stem 22 is erected in an upward biased state.

オーバーキャップ１０は、上面視円形状の天板部１１と、この天板部１１の外周縁からほぼ垂下してなる筒状の外筒部１２と、外筒部１２よりも小径とされるとともに、天板部１１の裏面に垂設された嵌合筒部１３と、を備え、この嵌合筒部１３の下端開口部の内周面がマウンティングカップ２６の外周面に嵌合することにより、エアゾール容器２０に取り付けられてオーバーキャップ付きエアゾール容器が構成されている。 The overcap 10 has a top plate portion 11 that is circular when viewed from above, a cylindrical outer tube portion 12 that is substantially suspended from the outer peripheral edge of the top plate portion 11, and a smaller diameter than the outer tube portion 12. A fitting cylinder portion 13 suspended from the back surface of the top plate portion 11, and by fitting the inner peripheral surface of the lower end opening of the fitting cylinder portion 13 to the outer peripheral surface of the mounting cup 26, An aerosol container with an overcap is configured by being attached to the aerosol container 20.

また、このオーバーキャップ付きエアゾール容器において、天板部１１の裏面が噴霧ヘッド２３の上面と対向している。図示の例では、天板部１１の裏面においてその径方向中央部が噴霧ヘッド２３の上面と対向している。さらに、外筒部１２の外径とエアゾール容器２０の胴部２４の外径とは同等となっている。
ここで、オーバーキャップ付きエアゾール容器の上面視において、天板部１１、外筒部１２および嵌合筒部１３の各径方向中央部と、エアゾール容器２０の径方向中央部とは一致しており、以下、これらの径方向中央部を結ぶ仮想直線を中心軸線Ｏという。 Moreover, in this aerosol container with an overcap, the back surface of the top plate portion 11 faces the top surface of the spray head 23. In the illustrated example, the central portion in the radial direction on the back surface of the top plate portion 11 faces the upper surface of the spray head 23. Furthermore, the outer diameter of the outer cylinder part 12 and the outer diameter of the trunk | drum 24 of the aerosol container 20 are equivalent.
Here, in the top view of the aerosol container with an overcap, each radial center part of the top plate part 11, the outer cylinder part 12 and the fitting cylinder part 13 coincides with the radial center part of the aerosol container 20. Hereinafter, an imaginary straight line connecting these radial central portions is referred to as a central axis O.

ここで、天板部１１には、前記中心軸線Ｏを中心とする半円形状の押圧板１６がヒンジ部１７回りに下方に折り曲げ可能に区画され、また、このオーバーキャップ１０の内部には、図２に示されるように、一対の支持板１８が、これら１８の間を前記折り曲げられた押圧板１６が通過可能となるように前記中心軸線Ｏを径方向で挟んで互いに対向して設けられている。 Here, the top plate portion 11 is partitioned with a semicircular pressing plate 16 centered on the central axis O so as to be bent downward around the hinge portion 17, and inside the overcap 10, As shown in FIG. 2, a pair of support plates 18 are provided opposite to each other with the central axis O in the radial direction so that the bent pressing plate 16 can pass between the support plates 18. ing.

すなわち、押圧板１６をヒンジ部１７回りに下方に折り曲げて支持板１８同士の間を通過させるときに、半円形状とされた押圧板１６においてその両周端部に後述の押下端部１６ａ側で連なるヒンジ部近傍部分１６ｂを、両支持板１８の表面１８ｂに押し付けつつ、押圧板１６を、これらの支持板１８の互いに対向する側面１８ａ同士の間に押し込み、前記ヒンジ部近傍部分１６ｂおよび支持板１８の少なくとも一方を弾性変形させ、ヒンジ部近傍部分１６ｂを、前記側面１８ａを乗り越えさせて裏面１８ｃ側に至らせることによって、この裏面１８ｃに引っ掛けるようになっている。これにより、押圧板１６の、前記折り曲げた方向と反対方向の移動が規制され、オーバーキャップ１０をエアゾール容器２０に嵌合した状態で、この押圧板１６においてヒンジ部１７の反対側に位置する押下端部１６ａが、噴霧ヘッド２３の上面を押し下げるようになっている。 That is, when the pressing plate 16 is bent downward around the hinge portion 17 and passed between the support plates 18, the pressing plate 16 having a semicircular shape has a pressing end portion 16a side described later on both circumferential ends thereof. The pressing plate 16 is pushed between the side surfaces 18a of the support plates 18 facing each other while pressing the hinge portion vicinity portion 16b connected to each other on the surface 18b of the both support plates 18, thereby supporting the hinge portion vicinity portion 16b and the support portion. At least one of the plates 18 is elastically deformed, and the vicinity of the hinge portion 16b is moved over the side surface 18a to reach the back surface 18c side, thereby being hooked on the back surface 18c. Thereby, the movement of the pressing plate 16 in the direction opposite to the bent direction is restricted, and the pressing plate 16 is positioned on the opposite side of the hinge portion 17 with the overcap 10 fitted to the aerosol container 20. The end portion 16 a pushes down the upper surface of the spray head 23.

なお、ヒンジ部１７は、天板部１１の裏面において、前記中心軸線Ｏと半円形状とされた押圧板１６の両周端部とを通る直線に沿って延びる凹部とされている。また、前述のように折り曲げる前の押圧板１６の外周縁は、この押圧板１６の折り曲げにより容易に破断可能なブリッジ（弱化部）１１ａを介して天板部１１と連結されている。 In addition, the hinge part 17 is made into the recessed part extended along the straight line which passes along the said center axis line O and the both peripheral edge parts of the press board 16 made into the semicircle shape in the back surface of the top-plate part 11. FIG. Further, as described above, the outer peripheral edge of the pressing plate 16 before being bent is connected to the top plate portion 11 via a bridge (weakening portion) 11 a that can be easily broken by bending the pressing plate 16.

さらに、図示の例では、嵌合筒部１３の内周面に、支持板１８の裏面１８ｃと対向するように、この支持板１８とほぼ同形同大の挟持板１９が一体に連結されている。これにより、押圧板１６を前述のように折り曲げて、前記ヒンジ部近傍部分１６ｂを支持板１８の裏面１８ｃ側に至らせたときに、このヒンジ部近傍部分１６ｂが、支持板１８の裏面１８ｃと挟持板１９との間に挟まれるようになっている。
以上より、押圧板１６は、ブリッジ１１ａを破断してこの押圧板１６の押下端部１６ａをこのオーバーキャップ１０の内部に進入させたときに、このオーバーキャップ１０をエアゾール容器２０に装着した状態で、前記押下端部１６ａがステム２２を押し下げる残留ガス抜き姿勢に保持されるようになっている。
なお、支持板１８と挟持板１９との間隔は、押圧板１６の厚さと同等となっている。 Further, in the illustrated example, a holding plate 19 having substantially the same shape and the same size as the support plate 18 is integrally connected to the inner peripheral surface of the fitting cylinder portion 13 so as to face the back surface 18c of the support plate 18. Yes. Thus, when the pressing plate 16 is bent as described above and the hinge portion vicinity portion 16b is brought to the back surface 18c side of the support plate 18, the hinge portion vicinity portion 16b is connected to the back surface 18c of the support plate 18. It is sandwiched between the clamping plate 19.
As described above, when the pressing plate 16 breaks the bridge 11a and causes the pressing end 16a of the pressing plate 16 to enter the inside of the overcap 10, the overcap 10 is attached to the aerosol container 20. The pressing end portion 16a is held in a residual gas venting posture that pushes down the stem 22.
The interval between the support plate 18 and the sandwiching plate 19 is equal to the thickness of the pressing plate 16.

そして、本実施形態では、天板部１１の表面に、押圧板１６およびブリッジ１１ａを覆う蓋部材３０が着脱可能に設けられている。図示の例では、蓋部材３０は天板部１１と同形同大の円板とされ、天板部１１の表面に前記中心軸線Ｏと同軸上に取り付けられて、この蓋部材３０により天板部１１の表面がその全域にわたって覆われるようになっている。
ここで、互いに係合可能な第１、第２係合部３１、３２のうち、一方が天板部１１の表面に設けられるとともに、他方が蓋部材３０の裏面に設けられている。 And in this embodiment, the cover member 30 which covers the press board 16 and the bridge | bridging 11a is provided in the surface of the top-plate part 11 so that attachment or detachment is possible. In the illustrated example, the lid member 30 is a disk having the same shape and size as the top plate portion 11, and is attached to the surface of the top plate portion 11 coaxially with the central axis O. The surface of the part 11 is covered over the whole area.
Here, one of the first and second engaging portions 31 and 32 that can be engaged with each other is provided on the surface of the top plate portion 11, and the other is provided on the back surface of the lid member 30.

第１係合部３１は、図２および図３に示されるように、天板部１１の表面において押圧板１６およびブリッジ１１ａの外方に位置する部分に形成され、幅広孔３３と幅狭孔３４とがそれぞれの幅方向と直交する長手方向に連結された長穴形状の係合孔となっている。図示の例では、前記幅方向は天板部１１の径方向と一致し、前記長手方向は天板部１１の周方向と一致している。そして、第１係合部３１は、天板部１１の上面視矩形状とされて周方向に沿って延びる長穴となっている。 As shown in FIGS. 2 and 3, the first engagement portion 31 is formed in a portion of the surface of the top plate portion 11 located outside the pressing plate 16 and the bridge 11 a, and has a wide hole 33 and a narrow hole. 34 is an elongated hole-shaped engagement hole connected in the longitudinal direction orthogonal to the respective width direction. In the illustrated example, the width direction coincides with the radial direction of the top plate portion 11, and the longitudinal direction coincides with the circumferential direction of the top plate portion 11. And the 1st engaging part 31 is made into the rectangular shape of the top view of the top-plate part 11, and is a long hole extended along the circumferential direction.

また、第１係合部３１の内面のうち、天板部１１の周方向に沿って延在し、かつ天板部１１の径方向内側に位置する第１内面３１ａは、幅広孔３３および幅狭孔３４において面一とされて、幅広孔３３は幅狭孔３４よりも径方向外方に張り出すことによりこの幅狭孔３４よりも幅が広くなっている。なお、第１係合部３１は、天板部１１の表面に周方向に等間隔をあけて複数（図示の例では４つ）形成されている。 In addition, the first inner surface 31 a that extends along the circumferential direction of the top plate portion 11 and is located on the radially inner side of the top plate portion 11 among the inner surfaces of the first engaging portion 31 has a wide hole 33 and a width. The wide hole 33 is flush with the narrow hole 34, and is wider than the narrow hole 34 by projecting radially outward from the narrow hole 34. Note that a plurality of (four in the illustrated example) first engaging portions 31 are formed on the surface of the top plate portion 11 at equal intervals in the circumferential direction.

一方、第２係合部３２は、蓋部材３０の裏面に突設された係合凸部とされるとともに、この係合凸部は、蓋部材３０の裏面に連結された薄肉部３５と、この薄肉部３５の突出端に連結された厚肉部３６とを備えている。図示の例では、蓋部材３０をその裏面側から見たときの第２係合部３２の外形形状は、蓋部材３０の周方向に沿って延びる矩形状とされ、かつ第１係合部３１の幅広孔３３の上面視形状と同形同大とされており、第２係合部３２は幅広孔３３に挿入可能となっている。 On the other hand, the second engaging portion 32 is an engaging convex portion protruding from the back surface of the lid member 30, and the engaging convex portion includes a thin portion 35 connected to the back surface of the lid member 30, and And a thick portion 36 connected to the protruding end of the thin portion 35. In the illustrated example, the outer shape of the second engaging portion 32 when the lid member 30 is viewed from the back side is a rectangular shape extending along the circumferential direction of the lid member 30, and the first engaging portion 31. The second engagement portion 32 can be inserted into the wide hole 33.

また、第２係合部３２において蓋部材３０の径方向内方端面は面一とされて、厚肉部３６は薄肉部３５よりも径方向外方に張り出すことによりこの薄肉部３５よりも厚さが大きくなっている。本実施形態では、厚肉部３６の径方向外方端面は、薄肉部３５側から第２係合部３２の突出端に向かうに従い漸次、径方向内方に向けて傾斜している。さらに、薄肉部３５の蓋部材３０の裏面からの突出長さは、天板部１１の厚さと同等となっている。 Further, the radially inner end surface of the lid member 30 is flush with the second engaging portion 32, and the thick portion 36 protrudes outward in the radial direction from the thin portion 35, so that the thick portion 36 is larger than the thin portion 35. The thickness is increased. In the present embodiment, the radially outer end surface of the thick portion 36 is gradually inclined inward in the radial direction from the thin portion 35 side toward the protruding end of the second engaging portion 32. Further, the protruding length of the thin portion 35 from the back surface of the lid member 30 is equal to the thickness of the top plate portion 11.

以上より、第１係合部３１の幅広孔３３に第２係合部３２を挿入した状態で、この第２係合部３２を第１係合部３１の幅狭孔３４内に向けてスライド移動させ、第２係合部３２において厚肉部３６の薄肉部３５側の端部３６ａを、天板部１１の裏面における幅狭孔３４の開口周縁部に引っ掛けることによって、第１、第２係合部３１、３２が互いに係合するようになっている。本実施形態では、第２係合部３２を第１係合部３１の幅広孔３３に挿入した状態で、オーバーキャップ１０において天板部１１側の部分、および蓋部材３０を相対的に前記中心軸線Ｏ回りに回転させることにより、第２係合部３２の薄肉部３５が、第１係合部３１の幅狭孔３４内をその前記長手方向における幅広孔３３と反対側の先端３４ａに向けて進入するようになっている。 As described above, in a state where the second engagement portion 32 is inserted into the wide hole 33 of the first engagement portion 31, the second engagement portion 32 is slid toward the narrow hole 34 of the first engagement portion 31. By moving and engaging the end portion 36a on the thin portion 35 side of the thick portion 36 in the second engaging portion 32 with the opening peripheral portion of the narrow hole 34 on the back surface of the top plate portion 11, The engaging portions 31 and 32 are adapted to engage with each other. In the present embodiment, in the state where the second engagement portion 32 is inserted into the wide hole 33 of the first engagement portion 31, the portion on the top plate portion 11 side in the overcap 10 and the lid member 30 are relatively centered. By rotating around the axis O, the thin-walled portion 35 of the second engaging portion 32 is directed in the narrow hole 34 of the first engaging portion 31 toward the tip 34a opposite to the wide hole 33 in the longitudinal direction. To enter.

さらに、本実施形態では、第１係合部３１の幅狭孔３４の内面のうち、前記第１内面３１ａと径方向で対向する第２内面３４ｃにおいて前記長手方向の中央部に、突曲面状の係止凸部３４ｂが突設されている。この係止凸部３４ｂの頂部と前記第１内面３１ａとの間隔は、第２係合部３２の薄肉部３５の厚さよりも小さくなっている。 Furthermore, in the present embodiment, the inner surface of the narrow hole 34 of the first engaging portion 31 has a protruding curved surface at the central portion in the longitudinal direction on the second inner surface 34c that radially faces the first inner surface 31a. The locking projection 34b is projected. The distance between the top of the locking projection 34 b and the first inner surface 31 a is smaller than the thickness of the thin portion 35 of the second engagement portion 32.

これにより、第１係合部３１の幅広孔３３に第２係合部３２を挿入した状態で、この第２係合部３２を、幅狭孔３４の前記先端３４ａに向けてスライド移動させたときに、第２係合部３２の薄肉部３５が、係止凸部３４ｂおよび第１内面３１ａに摺接しつつこの係止凸部３４ｂを通過するようになっている。そして、第２係合部３２が、幅狭孔３４の前記先端３４ａに到達したときに、薄肉部３５において蓋部材３０の周方向における両端面が、幅狭孔３４の前記先端３４ａと係止部３４ｂとで挟まれるようになっている。 Thereby, in a state where the second engagement portion 32 is inserted into the wide hole 33 of the first engagement portion 31, the second engagement portion 32 is slid toward the tip 34 a of the narrow hole 34. In some cases, the thin portion 35 of the second engagement portion 32 passes through the locking projection 34b while being in sliding contact with the locking projection 34b and the first inner surface 31a. When the second engaging portion 32 reaches the tip 34 a of the narrow hole 34, both end surfaces in the circumferential direction of the lid member 30 in the thin portion 35 are engaged with the tip 34 a of the narrow hole 34. It is designed to be sandwiched between the portions 34b.

以上のように構成されたオーバーキャップ付きエアゾール容器では、図１および図２に示されるように蓋部材３０を天板部１１に取り付けた状態から、まず、蓋部材３０を、第２係合部３２が第１係合部３１の幅広孔３３に向けて移動するように、前記中心軸線Ｏ回りに回転させる。この際、第２係合部３２の薄肉部３５が係止凸部３４ｂを乗り越え、薄肉部３５は、係止凸部３４ｂと前記第１内面３１ａとで挟まれて、これらの係止凸部３４ｂおよび前記第１内面３１ａに摺接しながら、第１係合部３１の幅広孔３３に到達する。これにより、厚肉部３６の前記端部３６ａの、天板部１１の裏面における幅狭孔３４の開口周縁部への引っ掛かりが解放され、蓋部材３０を上方に持ち上げたときに蓋部材３０が天板部１１から取り外される。 In the aerosol container with an overcap configured as described above, the lid member 30 is first moved to the second engaging portion from the state in which the lid member 30 is attached to the top plate portion 11 as shown in FIGS. Rotate about the central axis O so that 32 moves toward the wide hole 33 of the first engaging portion 31. At this time, the thin portion 35 of the second engaging portion 32 gets over the locking convex portion 34b, and the thin portion 35 is sandwiched between the locking convex portion 34b and the first inner surface 31a, and these locking convex portions. 34b and the first inner surface 31a are slidably contacted to reach the wide hole 33 of the first engaging portion 31. Thereby, the hook of the end portion 36a of the thick portion 36 to the opening peripheral edge of the narrow hole 34 on the back surface of the top plate portion 11 is released, and the lid member 30 is lifted when the lid member 30 is lifted upward. It is removed from the top plate part 11.

次に、押圧板１６をヒンジ部１７回りに下方に折り曲げ、押下端部１６ａにより噴霧ヘッド２３の上面を押し下げて残留ガスを抜き出す。ここで、押圧板１６をヒンジ部１７回りに折り曲げて、前記ヒンジ部近傍部分１６ｂを支持板１８の裏面１８ｃに引っ掛けたときに、このヒンジ部近傍部分１６ｂは、支持板１８の裏面１８ｃと挟持板１９との間に挟まれるので、押圧板１６は、前記のように折り曲げた方向と反対方向の移動のみならず、この折り曲げた方向の移動をも規制されることになる。したがって、押圧板１６にステム２２からの押し上げ力が作用しても、この押圧板１６によるステム２２の押し下げを確実に維持することが可能になる。 Next, the pressing plate 16 is bent downward around the hinge portion 17, and the upper surface of the spray head 23 is pushed down by the pressing end portion 16a to extract the residual gas. Here, when the pressing plate 16 is bent around the hinge portion 17 and the hinge portion vicinity portion 16 b is hooked on the back surface 18 c of the support plate 18, the hinge portion vicinity portion 16 b is sandwiched between the back surface 18 c of the support plate 18. Since the pressing plate 16 is sandwiched between the plates 19, not only the movement in the direction opposite to the direction bent as described above, but also the movement in the bent direction is restricted. Therefore, even if the pressing force from the stem 22 acts on the pressing plate 16, it is possible to reliably maintain the pressing of the stem 22 by the pressing plate 16.

以上説明したように本実施形態に係るオーバーキャップ１０によれば、天板部１１の表面に蓋部材３０が設けられているので、例えばオーバーキャップ付きエアゾール容器の流通過程や、需要者が内容物を使用するのにオーバーキャップ１０をエアゾール容器２０に対して繰り返し着脱する等の残留ガスを抜き出す前に、押圧板１６の表面側に外力が作用しても、この外力を蓋部材３０で受け止めて、この力がブリッジ１１ａに作用するのを防ぐことが可能になり、このブリッジ１１ａが不用意に破断するのを防止することができる。
さらに、ブリッジ１１ａが蓋部材３０で覆われているので、天板部１１にブリッジ１１ａが形成されたことによりこのオーバーキャップ１０の見映えが悪くなるのを防ぐことが可能になり、外観に優れたオーバーキャップ１０を提供することができる。 As described above, according to the overcap 10 according to the present embodiment, since the lid member 30 is provided on the surface of the top plate portion 11, for example, the distribution process of an aerosol container with an overcap or the contents of the consumer Even if an external force acts on the surface side of the pressing plate 16 before extracting the residual gas, such as repeatedly attaching and detaching the overcap 10 to the aerosol container 20, the external force is received by the lid member 30. The force can be prevented from acting on the bridge 11a, and the bridge 11a can be prevented from being carelessly broken.
Furthermore, since the bridge 11a is covered with the lid member 30, it is possible to prevent the appearance of the overcap 10 from being deteriorated due to the bridge 11a being formed on the top plate portion 11, and the appearance is excellent. An overcap 10 can be provided.

しかも、この蓋部材３０は、天板部１１の表面に着脱可能に設けられているので、残留ガスを抜き出すときには蓋部材３０を天板部１１から取り外すことが可能になり、このオーバーキャップ１０に優れた操作性を具備させることができる。
また、本実施形態では、天板部１１の表面に第１係合部３１が形成される一方、蓋部材３０の裏面に第２係合部３２が形成されているので、蓋部材３０を天板部１１の表面に着脱可能に設ける構成を容易かつ確実に実現することができる。 In addition, since the lid member 30 is detachably provided on the surface of the top plate portion 11, the lid member 30 can be detached from the top plate portion 11 when the residual gas is extracted. Excellent operability can be achieved.
In the present embodiment, the first engaging portion 31 is formed on the front surface of the top plate portion 11, while the second engaging portion 32 is formed on the back surface of the lid member 30. A configuration that is detachably provided on the surface of the plate portion 11 can be easily and reliably realized.

さらに、本実施形態では、第１係合部３１の幅狭孔３４の内面のうち、前記第１内面３
１ａと径方向で対向する第２内面３４ｃに、突曲面状の係止凸部３４ｂが突設されているので、天板部１１に取り付けられた蓋部材３０に、第２係合部３２を第１係合部３１の幅広孔３３側に向けてスライド移動させようとする外力が不意に作用しても、係止凸部３４ｂに、第２係合部３２の薄肉部３５において蓋部材３０の周方向における端面が引っ掛かることにより、蓋部材３０がこのようにスライド移動するのを防ぐことができる。したがって、残留ガスを抜き出す前に不用意に蓋部材３０が天板部１１から外れるのを防ぐことが可能になり、前述の作用効果が確実に奏功されることになる。 Further, in the present embodiment, among the inner surfaces of the narrow holes 34 of the first engaging portion 31, the first inner surface 3.
Since a protruding convex locking projection 34b is provided on the second inner surface 34c, which is opposed to 1a in the radial direction, the second engagement portion 32 is attached to the lid member 30 attached to the top plate portion 11. Even if an external force to be slid toward the wide hole 33 side of the first engaging portion 31 acts unexpectedly, the lid member 30 is applied to the locking convex portion 34b at the thin portion 35 of the second engaging portion 32. Since the end surface in the circumferential direction is caught, the lid member 30 can be prevented from sliding in this way. Therefore, it is possible to prevent the lid member 30 from being inadvertently detached from the top plate portion 11 before extracting the residual gas, and the above-described effects can be reliably achieved.

なお、本発明の技術的範囲は前記実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、前記実施形態では、第１係合部３１を天板部１１に形成し、第２係合部３２を蓋部材３０の裏面に形成したが、これとは逆に、第１係合部３１を蓋部材３０に形成し、第２係合部３２を天板部１１に形成してもよい。

A locking portion 44 for locking the lid member 42 is provided on the portion 43, and the pressing plate 16 is broken from the back surface side of the top plate portion 41 while the overcap 40 is removed from the aerosol container 20. A configuration may be employed in which the lid member 42 is pushed up by the pressing plate 16 and is disengaged from the locking portion 44 when pushed up.

図示の例では、天板部４１は、外筒部１２と嵌合筒部１３とを連結する外周部分４１ａが、この外周部分４１ａの径方向内方に位置する中央部分４１ｂよりも前記中心軸線Ｏ方向の下方に位置されるように２段形状となっている。そして、押圧板１６およびブリッジ１１ａは、中央部分４１ｂに形成されている。
また、囲繞筒部４３は、外筒部１２の内径および外径と同等とされ、前記外周部分４１ａの表面に立設されている。さらに、この囲繞筒部４３の前記中心軸線Ｏ方向の上端、つまり上端開口面における前記中心軸線Ｏ方向の位置は、天板部４１の中央部分４１ｂの表面における前記中心軸線Ｏ方向の位置と同等となっている。 In the illustrated example, the central plate 41 has an outer peripheral portion 41a that connects the outer cylindrical portion 12 and the fitting cylindrical portion 13 more than the central portion 41b that is located radially inward of the outer peripheral portion 41a. It has a two-stage shape so as to be positioned below the O direction. The pressing plate 16 and the bridge 11a are formed in the central portion 41b.
Moreover, the surrounding cylinder part 43 is made equivalent to the inner diameter and outer diameter of the outer cylinder part 12, and is erected on the surface of the outer peripheral part 41a. Furthermore, the upper end of the surrounding cylinder portion 43 in the direction of the central axis O, that is, the position of the upper end opening surface in the direction of the central axis O is the same as the position of the central portion 41 b of the top plate portion 41 in the direction of the central axis O. It has become.

また、蓋部材４２は円板状体とされて、その裏面において外周縁部４２ａを除いた部分はその全域が厚さ方向に凹んだ凹部４２ｂとなっている。そして、この蓋部材４２を囲繞筒部４３内に配置した状態で、天板部４１の表面においてブリッジ１１ａよりも径方向外方に位置する部分に、蓋部材４２の前記外周縁部４２ａが当接することによって、押圧板１６およびブリッジ１１ａが、蓋部材４２の凹部４２ｂに非接触状態で覆われるようになっている。図示の例では、凹部４２ｂの深さは、前記中央部分４１ｂの、外周部分４１ａの表面からの突出高さ以上となっている。また、蓋部材４２の前記外周縁部４２ａは、天板部４１の外周部分４１ａの表面に当接している。さらに、蓋部材４２の表面は、この蓋部材４２を囲繞筒部４３内に配置した状態で、この囲繞筒部４３の上端開口面よりも前記中心軸線Ｏ方向の上方に位置している。 Further, the lid member 42 is a disk-like body, and a portion of the back surface excluding the outer peripheral edge portion 42a is a concave portion 42b whose entire region is recessed in the thickness direction. Then, in a state where the lid member 42 is disposed in the surrounding cylinder portion 43, the outer peripheral edge portion 42a of the lid member 42 is applied to a portion of the surface of the top plate portion 41 that is positioned radially outward from the bridge 11a. By contacting, the pressing plate 16 and the bridge 11a are covered with the recess 42b of the lid member 42 in a non-contact state. In the illustrated example, the depth of the recess 42b is equal to or higher than the protruding height of the central portion 41b from the surface of the outer peripheral portion 41a. Further, the outer peripheral edge portion 42 a of the lid member 42 is in contact with the surface of the outer peripheral portion 41 a of the top plate portion 41. Further, the surface of the lid member 42 is positioned above the upper end opening surface of the surrounding tube portion 43 in the direction of the central axis O in a state where the lid member 42 is disposed in the surrounding tube portion 43.

When arranged in the surrounding cylinder part 43 from the side, the first locking part 44a formed on the lid member 42 is more in the direction of the central axis O than the second locking part 44b formed on the surrounding cylinder part 43. The lid member 42 is locked in the surrounding cylinder part 43 by being positioned below.

以上のように構成されたオーバーキャップ４０では、このキャップ４０をエアゾール容器２０から取り外した後に、押圧板１６を、天板部４１の裏面側からヒンジ部１７回りに上方に折り曲げてブリッジ１１ａを破断しつつ押し上げ、この押圧板１６により蓋部材４２を押し上げて、蓋部材４２に形成された第１係止部４４ａを、囲繞筒部４３に形成された第２係止部４４ｂを乗り越えさせることによって、この蓋部材４２を囲繞筒部４３から外す。その後、押圧板１６をヒンジ部１７回りに下方に折り曲げて、前記実施形態と同様にして、押圧板１６の押下端部１６ａにより噴霧ヘッド２３の上面を押し下げて残留ガスを抜き出す。 In the overcap 40 configured as described above, after removing the cap 40 from the aerosol container 20, the pressing plate 16 is bent upward around the hinge portion 17 from the back side of the top plate portion 41 to break the bridge 11 a. While pushing up, the lid member 42 is pushed up by the pressing plate 16, and the first locking portion 44 a formed on the lid member 42 is moved over the second locking portion 44 b formed on the surrounding cylinder portion 43. The lid member 42 is removed from the surrounding cylinder portion 43. Thereafter, the pressing plate 16 is bent downward around the hinge portion 17, and the upper surface of the spray head 23 is pushed down by the pressing end portion 16 a of the pressing plate 16 to extract the residual gas in the same manner as in the above embodiment.

Even if an external force acts on the surface side of the lid member 42 before extracting the residual gas, the lid member 42 does not move because it is in contact with the surface of the top plate portion 41.

さらに、本実施形態では、蓋部材４２の裏面に凹部４２ｂが形成され、この蓋部材４２を囲繞筒部４３内に配置した状態で、天板部４１の表面においてブリッジ１１ａよりも径方向外方に位置する部分に、蓋部材４２の前記外周縁部４２ａが当接することによって、押圧板１６およびブリッジ１１ａが、蓋部材４２の凹部４２ｂに非接触状態で覆われるようになっているので、蓋部材４２に外力が作用しても、その力が押圧板１６およびブリッジ１１ａに伝わるのを防ぐことが可能になり、残留ガスを抜き出す前にブリッジ１１ａが不用意に破断するのを確実に防ぐことができる。 Furthermore, in the present embodiment, a recess 42 b is formed on the back surface of the lid member 42, and the lid member 42 is disposed in the surrounding cylinder portion 43, and is more radially outward than the bridge 11 a on the surface of the top plate portion 41. Since the outer peripheral edge portion 42a of the lid member 42 is in contact with the portion located at the position, the pressing plate 16 and the bridge 11a are covered with the recess 42b of the lid member 42 in a non-contact state. Even if an external force acts on the member 42, it is possible to prevent the force from being transmitted to the pressing plate 16 and the bridge 11a, and reliably prevent the bridge 11a from being inadvertently broken before the residual gas is extracted.

また、囲繞筒部４３は、天板部４１の表面において、ブリッジ１１ａが形成されている位置よりも径方向外方であればいずれに設けてもよい。
さらに、前記実施形態では、押圧板１６およびブリッジ１１ａが、蓋部材４２の凹部４２ｂに非接触状態で覆われた構成を示したが、押圧板１６およびブリッジ１１ａが蓋部材４２の凹部４２ｂに接触状態で覆われるようにしてもよい。
また、前記実施形態では、蓋部材４２を囲繞筒部４３内に配置した状態で、蓋部材４２の表面を、囲繞筒部４３の上端開口面よりも前記中心軸線Ｏ方向の上方に位置させたが、蓋部材４２の表面を、囲繞筒部４３の上端開口面と面一となるように位置させてもよいし、あるいは囲繞筒部４３の上端開口面よりも前記中心軸線Ｏ方向の下方に位置させてもよい。 The locking portion 44 is not limited to the illustrated example. For example, a locking protrusion is provided on the surrounding tube portion 43 so as to protrude inward in the radial direction with respect to the inner peripheral surface thereof. When the lid member 42 is disposed therein, the lid member 42 may be sandwiched between the engaging portion and the surface of the top plate portion 41 in the thickness direction, or the inner peripheral surface of the surrounding cylinder portion 43 and A locking recess may be formed on one of the outer peripheral surfaces of the lid member 42, and a locking protrusion that fits into the locking recess may be provided on the other.
Furthermore, the top plate portion 41 and the lid member 42 are not limited to the illustrated example, and for example, both the front and back surfaces may be flat across the entire area.
In addition, the surrounding cylinder portion 43 may be provided on the surface of the top plate portion 41 as long as it is radially outward from the position where the bridge 11a is formed.
Furthermore, in the said embodiment, although the press plate 16 and the bridge | bridging 11a showed the structure covered with the recessed part 42b of the cover member 42 in the non-contact state, the press plate 16 and the bridge | bridging 11a contacted the recessed part 42b of the cover member 42. It may be covered with a state.
In the embodiment, the surface of the lid member 42 is positioned above the upper end opening surface of the surrounding cylinder portion 43 in the direction of the central axis O in a state where the lid member 42 is disposed in the surrounding cylinder portion 43. However, the surface of the lid member 42 may be positioned so as to be flush with the upper end opening surface of the surrounding tube portion 43, or may be positioned below the upper end opening surface of the surrounding tube portion 43 in the direction of the central axis O. It may be located.

さらにまた、図１から図４では、蓋部材３０、４２として、天板部１１、４１の表面をその全域にわたって覆う構成を示したが、天板部１１、４１の表面のうち少なくとも押圧板１６およびブリッジ１１ａを覆うような構成であれば、前記実施形態に限られるものではない。 Further, in FIGS. 1 to 4, the caps 10 and 40 are attached to the aerosol container 20 by fitting the lower end opening of the fitting cylinder 13 of the overcaps 10 and 40 to the upper end of the aerosol container 20. However, instead of this, for example, when the male screw part and the female screw part respectively formed in the overcaps 10 and 40 and the aerosol container 20 are screwed together, the overcaps 10 and 40 become the aerosol container. The structure attached to 20 may be adopted.
Furthermore, in FIGS. 1 to 4, the cover members 30 and 42 are configured to cover the entire surface of the top plate portions 11 and 41 over the entire region. However, at least the pressing plate 16 among the surfaces of the top plate portions 11 and 41. And if it is the structure which covers the bridge | bridging 11a, it is not restricted to the said embodiment.

また、図１から図４で示した押圧板１６に代えて、押圧板を、その両側部がそれぞれ接続部を介して天板部１１、４１に一体に連結されるとともに、その両端部が上下動するようにこの接続部回りに回動自在に設けることにより、押圧板の一端部側を押し下げて押圧板を接続部回りに回動させたときに、このオーバーキャップをエアゾール容器２０に装着した状態で、押圧板は、前記一端部がステム２２を押し下げ、かつ他端部側が天板部１１、４１の表面から上方に突出した残留ガス抜き姿勢に保持されるような構成を採用してもよい。 Further, instead of the pressing plate 16 shown in FIGS. 1 to 4, the pressing plate is integrally connected to the top plate portions 11 and 41 through the connecting portions on both sides, and both end portions thereof are The overcap is attached to the aerosol container 20 when the one end side of the pressing plate is pushed down and the pressing plate is rotated around the connecting portion by being rotatably provided around the connecting portion so as to move. In this state, the pressing plate may adopt a configuration in which the one end portion pushes down the stem 22 and the other end side is held in a residual gas venting posture protruding upward from the surfaces of the top plate portions 11 and 41. Good.

この場合、エアゾール容器２０内の残留ガスを抜き出すときに、押圧板は、その前記一端部がステム２２を押し下げる一方、前記他端部側が天板部１１、４１の表面から上方に突出した残留ガス抜き姿勢に保持されるので、残留ガスを抜き出す前後で、押圧板の前記他端部側における前記突出の有無によりエアゾール容器用オーバーキャップの外観形状を大きく異ならせることが可能になる。したがって、残留ガスを抜き出した人がこの容器を放置した後、例えば、残留ガスを抜き出した人とは別の人等がこの容器を見かけたときに、その人がこの容器から離れた位置にいてもそこから見た外観で、残留ガスが既に抜き出されたかどうかを一目で判別することができる。 In this case, when extracting the residual gas in the aerosol container 20, the pressing plate has its one end pushed down the stem 22, while the other end protrudes upward from the surfaces of the top plate portions 11 and 41. Since it is held in the extraction posture, the appearance shape of the aerosol container overcap can be greatly varied depending on the presence or absence of the protrusion on the other end side of the pressing plate before and after extracting the residual gas. Therefore, after a person who has extracted residual gas leaves the container, for example, when a person other than the person who has extracted residual gas sees the container, the person is away from the container. In addition, it is possible to determine at a glance whether the residual gas has already been extracted from the appearance as seen from there.

さらに、この押圧板に代えて、天板部１１、４１に押圧板が取り外し可能に区画されるとともに、この押圧板を取り外すことにより天板部１１、４１に開口部が形成され、このオーバーキャップの内部には、前記開口部に、天板部１１、４１から取り外された押圧板をその外周縁における一端部側から差し込んだときに、押圧板の外周縁における両側部にそれぞれ形成された第１押圧板係合部に各別に係合する一対の第２押圧板係合部が設けられ、これらの第１、第２押圧板係合部を互いに係合させることにより、このオーバーキャップをエアゾール容器２０に装着した状態で、押圧板は、前記一端部がステム２２を押し下げ、かつ他端部側が天板部１１、４１の表面から上方に突出した姿勢に保持される押圧板を採用してもよい。 Further, in place of the pressing plate, the pressing plate is removably defined on the top plate portions 11 and 41, and an opening is formed in the top plate portions 11 and 41 by removing the pressing plate. In the interior of the press plate, when the pressing plate removed from the top plate portions 11 and 41 is inserted into the opening from one end side of the outer peripheral edge thereof, the first plate is formed on both sides of the outer peripheral edge of the pressing plate. A pair of second pressing plate engaging portions that are individually engaged with the one pressing plate engaging portion are provided, and by engaging these first and second pressing plate engaging portions with each other, the overcap is aerosolized. In a state where the pressure plate is mounted on the container 20, the pressure plate employs a pressure plate that is held in a posture in which the one end portion pushes down the stem 22 and the other end portion protrudes upward from the surface of the top plate portions 11 and 41. Also good.

また、図１から図４で示した蓋部材３０、４２に代えて、例えば天板部１１、４１の表面に、剥離可能な接着剤を介して蓋部材の裏面を接着してもよいし、あるいは天板部１１、４１にヒンジ部を介して一体に連結された蓋部材を採用してもよく、さらにまた、蓋部材をキャップ状に形成して、その内周面に雌ねじを形成する一方、外筒部１２の外周面に雄ねじ部を形成して、これらの両ねじ部が着脱可能に螺合してなる構成を採用してもよい。
また、蓋部材３０、４２は、天板部１１、４１の表面にその全域を覆うように設けなくてもよい。 Further, instead of the lid members 30 and 42 shown in FIGS. 1 to 4, for example, the back surface of the lid member may be bonded to the surface of the top plate portions 11 and 41 via a peelable adhesive, Or you may employ | adopt the cover member integrally connected to the top-plate parts 11 and 41 via the hinge part, Furthermore, while forming a cover member in cap shape and forming an internal thread in the internal peripheral surface, A configuration may be adopted in which a male screw portion is formed on the outer peripheral surface of the outer cylinder portion 12 and both the screw portions are detachably screwed together.
The lid members 30 and 42 may not be provided on the surfaces of the top plate portions 11 and 41 so as to cover the entire area.

ここで、図１から図４では、オーバーキャップ１０、４０の内部に支持板１８と挟持板１９とを設けることにより、押圧板１６の、少なくとも前記折り曲げた方向と反対方向の移動を規制したが、これに代えて、例えば、支持板１８および挟持板１９を設けずに、噴霧ヘッド２３の上面に押圧板１６の押下端部１６ａが係止可能な係止部を形成してもよい。
さらに、押圧板１６と天板部１１、４１とを連結する弱化部としてブリッジ１１ａを示したが、これに代えて、押圧板１６を、この押圧板１６や天板部１１、４１よりも厚さが薄い薄肉部で囲繞することによって、天板部１１、４１に押圧板１６を区画するようにしてもよい。 Here, in FIGS. 1 to 4, the support plate 18 and the clamping plate 19 are provided inside the overcaps 10 and 40, so that the movement of the pressing plate 16 in at least the direction opposite to the bent direction is restricted. Instead of this, for example, without providing the support plate 18 and the clamping plate 19, a locking portion on which the pressing end 16 a of the pressing plate 16 can be locked may be formed on the upper surface of the spray head 23.
Furthermore, although the bridge 11a is shown as a weakening portion that connects the pressing plate 16 and the top plate portions 11 and 41, the pressing plate 16 is made thicker than the pressing plate 16 and the top plate portions 11 and 41 instead. The pressing plate 16 may be partitioned into the top plate portions 11 and 41 by surrounding with a thin thin portion.

さらにまた、図１から図４では、押圧板１６を平面視半円形状としたが、これに限らず、例えば矩形や多角形等としてもよい。
さらに、図１から図４では、押圧板１６の押下端部１６ａで噴霧ヘッド２３の上面を押し下げたが、これに代えて、例えば噴霧ヘッド２３をステム２２から取り外して、このステム２２の開口端面を押圧板１６の押下端部１６ａで押圧して押し下げてもよい。
また、残留ガスを抜き出す際に、押圧板１６をオーバーキャップ１０、４０の内部に進入させた後に、このオーバーキャップ１０、４０をエアゾール容器２０に装着してもよいし、あるいはオーバーキャップ１０、４０をエアゾール容器２０に装着した状態で、押圧板１６をオーバーキャップ１０、４０の内部に進入させてもよい。
さらに、エアゾール容器２０およびオーバーキャップ１０、４０の横断面形状は図示した円形に限らず、例えば多角形等であってもよい。
さらにまた、オーバーキャップ１０、４０は、蓋部材３０、４２を含めた全体を合成樹脂で形成してもよいし、あるいはオーバーキャップ１０、４０において、蓋部材３０、４２を除いた部分は合成樹脂により形成する一方、蓋部材３０、４２は例えば金属材料で形成してもよい。 Furthermore, in FIGS. 1 to 4, the pressing plate 16 has a semicircular shape in plan view, but is not limited thereto, and may be, for example, a rectangle or a polygon.
Further, in FIGS. 1 to 4, the upper surface of the spray head 23 is pushed down by the pressing end portion 16 a of the pressing plate 16, but instead, for example, the spray head 23 is removed from the stem 22 and the opening end surface of the stem 22 is removed. May be pressed by the pressing end 16a of the pressing plate 16 and pressed down.
Further, when extracting the residual gas, the overcap 10 or 40 may be attached to the aerosol container 20 after the pressing plate 16 enters the inside of the overcap 10 or 40, or the overcap 10 or 40 may be attached. The pressure plate 16 may be allowed to enter the overcaps 10 and 40 in a state where the is attached to the aerosol container 20.
Furthermore, the cross-sectional shape of the aerosol container 20 and the overcaps 10 and 40 is not limited to the illustrated circle, and may be, for example, a polygon.
Furthermore, the overcaps 10 and 40 may be entirely formed of a synthetic resin including the lid members 30 and 42, or portions of the overcaps 10 and 40 excluding the lid members 30 and 42 may be a synthetic resin. On the other hand, the lid members 30 and 42 may be formed of, for example, a metal material.

天板部に押圧板を連結する弱化部が、残留ガスを抜き出す前に不用意に破断するのを防ぐことができるとともに、外観に優れたオーバーキャップを提供することができる。 While the weakening part which connects a press plate to a top plate part can prevent breaking carelessly before extracting residual gas, the overcap excellent in the external appearance can be provided.
