Description

本発明はエアゾール容器用噴射装置に関し、グリップを握持した状態でトリガーを引くことで着脱交換可能に取り付けられるエアゾール容器の内容物を噴射する形式に用いられるエアゾール容器用噴射装置に関する。 TECHNICAL FIELD The present invention relates to an aerosol container injection device, and more particularly to an aerosol container injection device used for injecting the contents of an aerosol container that is detachably attached by pulling a trigger while holding a grip.

従来から、整髪料、殺虫剤、塗料、洗浄剤等を噴射するには、これらの液体・溶液・溶剤等をエアゾール容器に充填し、該エアゾール容器のバルブを開閉操作することにより該バルブに連通したノズル機構から噴射することで行われている。 Conventionally, in order to spray hair conditioners, insecticides, paints, cleaning agents, etc., these liquids, solutions, solvents, etc. are filled into an aerosol container, and the valve of the aerosol container is opened and closed to communicate with the valve. This is done by spraying from the nozzle mechanism.

バルブの開閉操作としては、一般的なエアゾール容器では該エアゾール容器のバルブ先端に被冠状態で取り付けられたノズル付きのキャップ体を押下することで行われる構成が広く知られている（例えば、特許文献１等参照）。 As a valve opening / closing operation, in a general aerosol container, a configuration that is performed by pressing a cap body with a nozzle attached in a crowned state to a valve tip of the aerosol container is widely known (for example, a patent Reference 1 etc.).

また、バルブの開閉操作としては、ノズル付きのキャップ体の押下に換えてバルブに連通する構成のノズル機構を操作するトリガーを備え、グリップを握持した状態で前記トリガーに引っ掛けた人差し指を引き絞る操作をすることで行われる構成も知られている（例えば、特許文献２〜５等参照）。 In addition, as a valve opening / closing operation, a trigger for operating a nozzle mechanism configured to communicate with the valve instead of pressing a cap body with a nozzle is provided, and the index finger hooked on the trigger is pulled down while holding the grip. The structure performed by operating is also known (for example, refer patent documents 2-5 etc.).

特許第３０４９４２４号Japanese Patent No. 3049424 特開２００１−３１５８７２号JP 2001-315872 A 特開２００７−０２２６５９号JP 2007-022659 特許第３９５９４４２号Patent No. 3959442 特許第３８９７５８９号Patent No. 3897589

特許文献１の技術では、簡単な構造によりエアゾール容器の内容物の噴射が可能であり広く普及しているが、内容物の種類や容量等によって異なる大きさのエアゾール容器を人差し指を除いた４本の指で若干不安定な状態で持ち、バルブに内蔵されたスプリングを付勢力に抗して圧縮させながらノズル付きの小さなキャップ体を人差し指一本の指先のみで強く押下する必要があることから操作性が低く、指先の力が乏しい使用者の場合、噴射操作が困難であるだけでなく、押下時の力みによって噴射方向が不安定となってしまったり、キャップ体から指先がずれることで噴射物に触れてしまう等の問題を有している。 In the technology of Patent Document 1, it is possible to inject the contents of an aerosol container with a simple structure and is widely used. However, four aerosol containers with different sizes depending on the type and capacity of the contents, excluding the index finger, are used. Because it is necessary to press the small cap body with a nozzle strongly with only one fingertip while holding the spring in a slightly unstable state and compressing the spring built in the valve against the urging force In the case of users with low fingertip strength, not only the injection operation is difficult, but also the injection direction becomes unstable due to the force when pressed or the fingertip is displaced from the cap body It has problems such as touching things.

この点、特許文献２〜５の技術では、特許文献１が抱えていた操作性の問題は解決されており、安定した握持状態で、より小さな力で容易に内容物の噴射が可能となっている。 In this regard, the techniques of Patent Documents 2 to 5 solve the problem of operability that Patent Document 1 has, and can easily inject contents with a smaller force in a stable gripping state. ing.

しかしこれらの技術では、エアゾール容器に取り付けられた噴射構成部分、即ち、ノズル機構、トリガー機構、グリップ及びこれらの機構を備えた噴射装置の本体構成が、特許文献１のような単なるノズル付きの小さなキャップ体とは異なり、多数の構成部品から成る大型の機構となるためコスト高であるという問題点を有している。 However, in these techniques, the injection component attached to the aerosol container, that is, the nozzle mechanism, the trigger mechanism, the grip, and the main body configuration of the injection device including these mechanisms are small in size with a simple nozzle as in Patent Document 1. Unlike the cap body, it has a problem of high cost because it is a large-sized mechanism composed of a large number of components.

そこで本発明の課題は、より小さな力で容易に内容物の噴射が安定した握持状態で可能な構成である、ノズル機構、トリガー機構及びグリップを備えた噴射装置でありながら低コスト化も可能なエアゾール容器用噴射装置を提供することにある。 Accordingly, an object of the present invention is to enable cost reduction while being a jet device equipped with a nozzle mechanism, a trigger mechanism, and a grip, which is capable of easily injecting contents with a small force in a stable gripping state.

以下、本発明に係るエアゾール容器用噴射装置を詳細に説明する。 Hereinafter, the aerosol container injection device according to the present invention will be described in detail.

図１〜図３に示すように、本発明に係るエアゾール容器用噴射装置（以下、単に噴射装置ということもある。）１は、エアゾール容器２のバルブ２０に連通するノズル機構１０と、前記バルブ２０の開閉を操作するトリガー機構１１と、持ち手となるグリップ１２とを備え、エアゾール容器２が着脱交換可能に取り付けられる構成を有する。 As shown in FIGS. 1 to 3, an aerosol container injection device (hereinafter sometimes simply referred to as an injection device) 1 according to the present invention includes a nozzle mechanism 10 communicating with a valve 20 of an aerosol container 2, and the valve 20 has a trigger mechanism 11 for operating opening and closing, and a grip 12 as a handle, and has a configuration in which the aerosol container 2 is detachably attached.

更に噴射装置１は、加圧変形可能な内筒部１６と外筒部１３とを有する二重構造の本体を主構成とし、
前記外筒部１３の外周面の相対向する位置である二箇所には、内筒部１６方向に押圧可能な押圧操作部１４・１４が夫々形成され、
該二箇所の押圧操作部１・１４・の内側で且つ前記内筒部１６の外側の二箇所には、前記二箇所の押圧操作部１４・１４の夫々に一部が接続して押圧力の伝達が行われる押圧伝達部１５・１５が夫々形成され、
該押圧伝達部１５・１５によって押圧力が伝達される部分と直交する位置の内筒部１６の内周面には、前記エアゾール容器２のテーパー状肩部２１の上方に形成されると共に外周方向に突出した環状係止部２２に係止する突起爪１７が形成されており、
前記押圧操作部１４・１４への押圧操作によって前記押圧伝達部１５・１５を介して内筒部１６が変形し、該変形により前記突起爪１６が前記環状係止部２２から外側方向へ退避することで前記環状係止部２２への係止が解除される構成を有する。 Furthermore, the injection device 1 mainly has a double-structured main body having an inner cylinder part 16 and an outer cylinder part 13 that can be deformed under pressure,
At two locations that are opposite positions on the outer peripheral surface of the outer cylindrical portion 13, pressing operation portions 14 and 14 that can be pressed in the direction of the inner cylindrical portion 16 are formed, respectively.
Two portions inside the two pressing operation portions 1, 14, and outside the inner cylinder portion 16 are partially connected to the two pressing operation portions 14, 14, respectively. Press transmission parts 15 and 15 where transmission is performed are formed respectively.
On the inner peripheral surface of the inner cylindrical portion 16 at a position orthogonal to the portion where the pressing force is transmitted by the pressing force transmitting portions 15, 15, the outer peripheral direction is formed above the tapered shoulder portion 21 of the aerosol container 2. The projection claw 17 is formed to be locked to the annular locking portion 22 protruding to
The inner cylinder portion 16 is deformed via the pressure transmitting portions 15 and 15 by the pressing operation to the pressing operation portions 14 and 14, and the projecting claw 16 is retracted outward from the annular locking portion 22 by the deformation. In this way, the engagement with the annular locking portion 22 is released.

尚、「エアゾール容器２のテーパー状肩部２１の上方に」の「上方」とは、エアゾール容器２の通常の取扱時の状態、即ち、非使用時等の通常の姿勢である縦置きした場合における「上方」を云うものであり、本発明のように噴射装置１に対して横向き状態に取り付けられる場合には上方ではなくなることは云うまでもない。 The term “above” of “above the tapered shoulder 21 of the aerosol container 2” means that the aerosol container 2 is in a normal handling state, that is, in a normal posture such as when not in use. It is needless to say that it is no longer upward when it is attached to the injection device 1 in a sideways state as in the present invention.

尚また、ノズル機構１０、トリガー機構１１、グリップ１２の各構成及び形状並びに作用については、この種の噴射装置のノズル機構、トリガー機構、グリップとして公知公用のものを特別の制限なく採ることができ、更に、これらの材質、並びに噴射装置１の本体及び他の構成部材の材質についても、少なくとも内筒部１６及び外筒部１３が加圧変形可能な材質で構成されていれば、この種の噴射装置の材質として公知公用の材質（特に好ましくはポリエチレン、ポリプロピレン等に代表される可撓性合成樹脂）を用いることができる。 In addition, as for each configuration, shape, and action of the nozzle mechanism 10, the trigger mechanism 11, and the grip 12, well-known and publicly available nozzle mechanisms, trigger mechanisms, and grips of this type of injection device can be adopted without any particular limitation. Furthermore, with respect to these materials, and the material of the main body and other constituent members of the injection device 1, if at least the inner cylinder portion 16 and the outer cylinder portion 13 are made of a material that can be deformed by pressure, this kind of material is used. As the material of the injection device, a publicly known material (particularly preferably, a flexible synthetic resin typified by polyethylene, polypropylene, or the like) can be used.

前記押圧操作部１４・１４は、その周囲の少なくとも一部が外筒部１３とは切り離された構成（図１では横向きの略Ｕ字状の形状に切り離されている。）とすることが好ましく、かかる構成によって、押圧操作部１４・１４が設けられた外筒部１３の厚みや硬度等の影響を受け難い状態で該押圧操作部１４・１４への押圧操作を行うことができる。 It is preferable that at least a part of the periphery of the pressing operation portions 14 and 14 is separated from the outer cylinder portion 13 (in FIG. 1, the pressing operation portions 14 and 14 are separated into a substantially U-shaped shape facing sideways). With such a configuration, it is possible to perform a pressing operation on the pressing operation portions 14 and 14 in a state where they are hardly affected by the thickness and hardness of the outer cylinder portion 13 provided with the pressing operation portions 14 and 14.

前記押圧伝達部１５・１５は、前記押圧操作部１４・１４と前記内筒部１６とを接続する板状部材又は棒状部材から形成され、且つ前記押圧操作部１４・１４と前記内筒部１６とが一体的に形成された構成であることが好ましい。かかる構成によって、押圧操作部１４・１４からの押圧力を確実且つ直接的に伝達させることができる。 The pressure transmitting portions 15 and 15 are formed of plate-like members or rod-like members that connect the pressing operation portions 14 and 14 and the inner cylinder portion 16, and the pressing operation portions 14 and 14 and the inner cylinder portion 16. Are preferably formed integrally with each other. With this configuration, it is possible to reliably and directly transmit the pressing force from the pressing operation units 14 and 14.

前記グリップ１２は、少なくとも噴射時に前記エアゾール容器２のバルブ２０の軸線に交差する方向に延伸するように設けられる構成であることが好ましい。かかる構成によって、バズーカ砲やピストルの如き横噴射形式の噴射を行うことができるので噴射方向をより安定化させることができ、エアゾール容器２の内容物の命中度が向上する。 The grip 12 is preferably configured to extend at least in a direction intersecting the axis of the valve 20 of the aerosol container 2 at the time of injection. With such a configuration, it is possible to perform a lateral injection type injection such as a bazooka gun or a pistol, so that the injection direction can be further stabilized and the accuracy of the contents of the aerosol container 2 is improved.

次に、上記構成を有する本発明のエアゾール容器用噴射装置１に対するエアゾール容器２の着脱構成について説明する。 Next, the attachment / detachment structure of the aerosol container 2 with respect to the aerosol container injection apparatus 1 of the present invention having the above structure will be described.

先ず、噴射装置１にエアゾール容器２が取り付けられている状態について説明する。
噴射装置１に対してエアゾール容器２は図３に示すように、テーパー状肩部２１の上方（図３では左に倒した上体であるため左方）に形成された環状係止部２２が、内筒部１６内周面に形成された突起爪１７に係止することで取付固定状態が維持されている。この状態の内筒部１６の形状は図４に示すように、歪みのほとんど無い円形、即ち、円形である環状係止部２２と同様の大きさ（直径）及び形状となっており、図５に示すように内筒部１６の内周面がエアゾール容器２の環状係止部２２の外周に当接した状態で、且つ突起部１７が環状係止部２２に係止した状態となっている。この突起部１７による環状係止部２２への係止により、エアゾール容器２の噴射装置１に対する取付固定状態が維持されるのである。 First, a state where the aerosol container 2 is attached to the injection device 1 will be described.
As shown in FIG. 3, the aerosol container 2 has an annular locking portion 22 formed above the tapered shoulder portion 21 (to the left in FIG. 3 because it is an upper body tilted to the left). The mounting and fixing state is maintained by engaging with the projection claw 17 formed on the inner peripheral surface of the inner cylinder portion 16. As shown in FIG. 4, the shape of the inner cylindrical portion 16 in this state is a circular shape having almost no distortion, that is, the same size (diameter) and shape as the circular annular locking portion 22. As shown in FIG. 2, the inner peripheral surface of the inner cylindrical portion 16 is in contact with the outer periphery of the annular locking portion 22 of the aerosol container 2 and the projection 17 is locked to the annular locking portion 22. . The attachment and fixing state of the aerosol container 2 with respect to the injection device 1 is maintained by the locking of the protrusion 17 to the annular locking portion 22.

次に、エアゾール容器２の内容物が空になった際や他の内容物のエアゾール容器２に交換する際等に噴射装置１からエアゾール容器２を取り外す場合について説明する。
噴射装置１からエアゾール容器２を取り外すには、該エアゾール容器２の環状係止部２２に対する内筒部１６の突起部１７による係止を解除する。
この係止の解除は、押圧操作部１４・１４を図４に示す符号Ｘで示す方向に押圧操作する。この押圧操作により、図５に示すように、押圧操作部１４・１４は内側方向に移動する。この押圧操作部１４・１４の押圧操作による移動に伴い、該押圧操作部１４・１４の内側に形成された押圧伝達部１５・１５を介して押圧力が内筒部１６に伝達される。押圧力の伝達により、図５に示すように内筒部１６は円形から楕円形に変形する。内筒部１６の変形に伴い、該内筒部１６の内周面であって、押圧力が伝達される部分と直交する位置に形成された突起爪１７が外側方向へ退避する。突起爪１７の退避により、図７に示すように環状掛止部２２（図５では点線で示している。）への係止が解除される。係止の解除により、エアゾール容器２は容易に噴射装置１から取り外すことができる。 Next, the case where the aerosol container 2 is removed from the injection device 1 when the contents of the aerosol container 2 are emptied or replaced with the aerosol container 2 of other contents will be described.
In order to remove the aerosol container 2 from the injection device 1, the locking by the protrusion 17 of the inner cylinder part 16 with respect to the annular locking part 22 of the aerosol container 2 is released.
To release the lock, the pressing operation portions 14 and 14 are pressed in the direction indicated by the symbol X shown in FIG. By this pressing operation, as shown in FIG. 5, the pressing operation units 14 and 14 move inward. Along with the movement of the pressing operation portions 14 and 14 by the pressing operation, the pressing force is transmitted to the inner cylinder portion 16 through the press transmitting portions 15 and 15 formed inside the pressing operation portions 14 and 14. Due to the transmission of the pressing force, the inner cylindrical portion 16 is deformed from a circular shape to an elliptical shape as shown in FIG. Along with the deformation of the inner cylinder portion 16, the projection claw 17 formed on the inner peripheral surface of the inner cylinder portion 16 at a position orthogonal to the portion to which the pressing force is transmitted is retracted outward. By retracting the protruding claws 17, the engagement with the annular latching portion 22 (shown by the dotted line in FIG. 5) is released as shown in FIG. By releasing the lock, the aerosol container 2 can be easily detached from the injection device 1.

以上、本発明に係るエアゾール容器用噴射装置の一実施例について説明したが、本発明は上記実施例に限定されず、本発明の技術的範囲内において他の態様を採ることもできる。 As mentioned above, although one Example of the injection apparatus for aerosol containers concerning this invention was described, this invention is not limited to the said Example, Other aspects can also be taken within the technical scope of this invention.

例えば、上記実施例では、押圧操作部１４・１４は、その周囲の一部が外筒部１３とは切り離された構成となっているが、本発明は当該構成に限定されず、押圧操作部１４・１４が全周に亘って外筒部１３から切り離された構成としてもよいし、外筒部１３とは切り離されずに全周に亘って接続された構成としてもよい。更に、押圧操作部１４・１４の周囲を薄肉部で形成することで押圧操作可能な構成とすることもできる。 For example, in the above-described embodiment, the pressing operation portions 14 and 14 have a configuration in which a part of the periphery thereof is separated from the outer cylinder portion 13, but the present invention is not limited to this configuration, and the pressing operation portion 14 and 14 may be configured to be separated from the outer cylinder portion 13 over the entire circumference, or may be configured to be connected over the entire circumference without being separated from the outer cylinder portion 13.
