Description

本発明はトリガー式液体噴出器に関する。   The present invention relates to a trigger type liquid ejector.

特許文献１に記載の如く、トリガー式液体噴出器において、物流段階での落下時にノズルを保護するため、ノズルを被包するトリガーカバーを備えたものがある。トリガーカバーは、トリガー式液体噴出器の物流段階で、ノズルを被包するとともに、不用意に外れることを防止するため、トリガーボディの後部の内部空間に折り込まれて係止固定される。トリガーカバーは、トリガー式液体噴出器の使用段階では、トリガーボディから取外されて除去される。   As described in Patent Document 1, there is a trigger type liquid ejector that includes a trigger cover that encloses a nozzle in order to protect the nozzle when it is dropped at a physical distribution stage. The trigger cover is encased in the internal space of the rear part of the trigger body and locked in order to prevent the nozzle from being inadvertently removed while enclosing the nozzle at the distribution stage of the trigger type liquid ejector. The trigger cover is removed from the trigger body and removed when the trigger liquid ejector is used.

特開2002-2841（１頁、図１）JP 2002-2841 (1 page, Fig. 1)

特許文献１のトリガーカバーは、トリガー式液体噴出器の物流段階で、トリガー式液体噴出器の落下時にノズルを保護しようとするものであるが、該カバーの先端の天面、側面及び底面によりノズルを被包固定するものであり、ノズルに直接的に支持される。たとえ、トリガーカバーとノズルの間にクッション材を挟んだとしても、トリガーカバーはノズルに間接的に支持される。   The trigger cover of Patent Document 1 is intended to protect the nozzle when the trigger type liquid ejector falls in the distribution stage of the trigger type liquid ejector, and the nozzle is formed by the top, side and bottom surfaces of the tip of the cover. And is directly supported by the nozzle. Even if a cushion material is sandwiched between the trigger cover and the nozzle, the trigger cover is indirectly supported by the nozzle.

従って、トリガー式液体噴出器が内容液を収容した状態で逆さ向きに落下したときには、トリガーカバーに作用する衝撃荷重が直接的に、又はクッション材を介してノズルに及ぶ。衝撃荷重がノズルに及ぶ以上、ノズルの損傷を確実には防止できない。   Therefore, when the trigger type liquid ejector falls in the reverse direction while containing the content liquid, the impact load acting on the trigger cover reaches the nozzle directly or via the cushion material. As long as the impact load reaches the nozzle, damage to the nozzle cannot be reliably prevented.

トリガー式液体噴出器の軽量化を目的として構成部品の薄肉化を図ったりする場合には、衝撃荷重に対する耐久度のより確実な向上が必要とされる。   In order to reduce the thickness of the component parts for the purpose of reducing the weight of the trigger type liquid ejector, it is necessary to improve the durability against an impact load more surely.

尚、特許文献１のトリガーカバーは、トリガー式液体噴出器の使用段階ではトリガーボディから除去されるものであり、使用段階でノズルを保護するところが一切ない。   In addition, the trigger cover of patent document 1 is removed from a trigger body in the use stage of a trigger type liquid ejector, and there is no place which protects a nozzle in a use stage.

本発明の課題は、トリガー式液体噴出器において、落下時のノズルの損傷を確実に防止することにある。   An object of the present invention is to reliably prevent damage to a nozzle when dropped in a trigger type liquid ejector.

請求項１の発明は、トリガーボディの前部にノズルを設けてなり、該トリガーボディに支持したシュラウドにより該ノズルの少なくとも上側を覆い、該シュラウドは該ノズルの周囲の全周に対し空隙を介するトリガー式液体噴出器であって、該シュラウドと該トリガーボディとの間にばね体からなる緩衝手段を介装したものである。 The invention of claim 1 is constituted by a nozzle provided at the front of the trigger body covers at least upper side of the nozzle by a shroud which is supported by the trigger body, the shroud is through a gap with respect to the total circumference of the periphery of the nozzle A trigger-type liquid ejector , wherein a buffer means comprising a spring body is interposed between the shroud and the trigger body .

トリガー式液体噴出器１０は、図１の参考例に示す如く、容器１１の開口部に接続される通液体１２を、該容器１１に螺着されるキャップ１３により該容器１１に固定する。トリガー式液体噴出器１０は、通液体１２にトリガーボディ１４を嵌合して一体化し（通液体１２とトリガーボディ１４は一体成形されても可）、トリガーボディ１４の主筒１４Ａをキャップ１３の側から起立し、主筒１４Ａの中間部から前方にシリンダ筒１４Ｂを突設し、主筒１４Ａの上端部から前方に射出筒１４Ｃを突設している。 As shown in the reference example of FIG. 1, the trigger type liquid ejector 10 fixes the liquid 12 connected to the opening of the container 11 to the container 11 with a cap 13 screwed to the container 11. The trigger type liquid ejector 10 integrates the trigger body 14 by fitting the trigger body 14 to the fluid flow 12 (the fluid flow 12 and the trigger body 14 may be integrally formed), and the main cylinder 14A of the trigger body 14 is attached to the cap 13. Standing from the side, a cylinder cylinder 14B is projected forward from an intermediate portion of the main cylinder 14A, and an injection cylinder 14C is projected forward from the upper end of the main cylinder 14A.

トリガー式液体噴出器１０は、トリガーレバー１５の上端部をトリガーボディ１４の射出筒１４Ｃにおける前方側の両外側部に回動自在に枢着し、シリンダ筒１４Ｂに嵌合させたプランジャ１７の前端部にトリガーレバー１５の中間部の後面を係合させ、シリンダ筒１４Ｂに内蔵のスプリング１８によりプランジャ１７を介してトリガーレバー１５を前方に弾発させる。   The trigger type liquid ejector 10 has a front end of a plunger 17 which is pivotally attached to both front outer sides of the injection cylinder 14C of the trigger body 14 and fitted to the cylinder cylinder 14B. The rear surface of the middle part of the trigger lever 15 is engaged with the part, and the trigger lever 15 is repelled forward via the plunger 17 by a spring 18 built in the cylinder cylinder 14B.

トリガー式液体噴出器１０は、トリガーボディ１４の射出筒１４Ｃの前端小外径部に連結筒１９を嵌合し、連結筒１９の前端外径部にノズル２０を回動自在に嵌合する。ノズル２０は回動操作レバー２０Ａを備える。トリガー式液体噴出器１０は、回動操作レバー２０Ａによるノズル２０の回動で、連結筒１９とノズル２０が形成する液体吐出路を切換え開閉自在にする。   In the trigger type liquid ejector 10, the connecting cylinder 19 is fitted to the front end small outer diameter part of the injection cylinder 14 </ b> C of the trigger body 14, and the nozzle 20 is rotatably fitted to the front end outer diameter part of the connecting cylinder 19. The nozzle 20 includes a rotation operation lever 20A. The trigger type liquid ejector 10 is configured to freely open and close the liquid discharge path formed by the connecting cylinder 19 and the nozzle 20 by the rotation of the nozzle 20 by the rotation operation lever 20A.

トリガー式液体噴出器１０は、容器１１の内部に延びるディップチューブ２１を通液体１２の下端部に挿着し、通液体１２の内部に入側逆止弁２２、出側逆止弁２３を設けている。   The trigger type liquid ejector 10 has a dip tube 21 extending inside the container 11 inserted into the lower end of the liquid 12, and an inlet side check valve 22 and an outlet side check valve 23 provided inside the liquid passage 12. ing.

これにより、トリガー式液体噴出器１０にあっては、トリガーレバー１５の引き操作に基づくプランジャ１７の加圧動作により、シリンダ筒１４Ｂ内の液体を出側逆止弁２３経由でノズル２０から噴出する。また、トリガーレバー１５の引き操作解除に基づくプランジャ１７の戻り動作で、容器１１内の液体を入側逆止弁２２経由でシリンダ筒１４Ｂに吸込む。   Accordingly, in the trigger type liquid ejector 10, the liquid in the cylinder cylinder 14 </ b> B is ejected from the nozzle 20 via the outlet check valve 23 by the pressurizing operation of the plunger 17 based on the pulling operation of the trigger lever 15. . Further, the liquid in the container 11 is sucked into the cylinder cylinder 14 </ b> B via the inlet check valve 22 by the return operation of the plunger 17 based on the release operation of the trigger lever 15.

トリガー式液体噴出器１０は、図１に示す如く、トリガーボディ１４に支持されて該トリガーボディ１４の上面部、背面部及び両側面部を覆うシュラウド３０により、ノズル２０の上側と、両側部（図１では両側部のうちの上側寄り部分、但し、両側部の全部でも可）を覆い、シュラウド３０とトリガーボディ１４との間に緩衝手段４０を介装した。   As shown in FIG. 1, the trigger type liquid ejector 10 is supported by the trigger body 14, and the shroud 30 covering the upper surface portion, the rear surface portion, and both side surface portions of the trigger body 14, the upper side of the nozzle 20 and both side portions (see FIG. In FIG. 1, the upper side portion of the both side portions, but all of the both side portions may be covered), and the buffer means 40 is interposed between the shroud 30 and the trigger body 14.

シュラウド３０は、トリガーボディ１４の主筒１４Ａにおける後方から、主筒１４Ａ、シリンダ筒１４Ｂ及び射出筒１４Ｃを覆うように被着可能にされ、主筒１４Ａに相対する背面３１、背面３１の上部から射出筒１４Ｃに沿ってノズル２０の前端部まで延びる天面３２、背面３１の下部から主筒１４Ａの後部まで延びる底面３３、背面３１、天面３２及び底面３３の両側縁から延びてトリガーボディ１４の全体（主筒１４Ａ、シリンダ筒１４Ｂ及び射出筒１４Ｃ）及びノズル２０の前端部を覆う両側面３４を備える。シュラウド３０の天面３２及び両側面３４の前側部分は、ノズル２０の前端部の前方位置（又は前端部と面一位置）まで延在し、ノズル２０の周囲の全周に対し空隙Ｇを介する。   The shroud 30 is attachable so as to cover the main cylinder 14A, the cylinder cylinder 14B, and the injection cylinder 14C from the rear side of the main cylinder 14A of the trigger body 14, and from the upper surface of the rear surface 31 and the rear surface 31 facing the main cylinder 14A. The trigger body 14 extends from the top surface 32 extending to the front end portion of the nozzle 20 along the injection cylinder 14C, the bottom surface 33 extending from the lower portion of the back surface 31 to the rear portion of the main tube 14A, and the both sides of the back surface 31, the top surface 32, and the bottom surface 33. (Both main cylinder 14 </ b> A, cylinder cylinder 14 </ b> B and injection cylinder 14 </ b> C) and both side surfaces 34 covering the front end of the nozzle 20. The front portions of the top surface 32 and the side surfaces 34 of the shroud 30 extend to the front position of the front end portion of the nozzle 20 (or the same position as the front end portion), and the gap G is interposed with respect to the entire circumference around the nozzle 20. .

シュラウド３０の天面３２の内面に設けた上係止部３５Ａをトリガーボディ１４の主筒１４Ａ又は射出筒１４Ｃの上面に設けた係止部３５Ｂに係止し、底面３３の前端側内面に設けた下係止部３６Ａをトリガーボディ１４の主筒１４Ａの後面に設けた係止部３６Ｂに係止することにより、シュラウド３０をトリガーボディ１４に係止固定状態で支持する。   The upper locking portion 35A provided on the inner surface of the top surface 32 of the shroud 30 is locked to the locking portion 35B provided on the upper surface of the main cylinder 14A or the injection cylinder 14C of the trigger body 14, and provided on the inner surface of the front end side of the bottom surface 33. The lower locking portion 36A is locked to the locking portion 36B provided on the rear surface of the main cylinder 14A of the trigger body 14, so that the shroud 30 is supported on the trigger body 14 in a locked state.

緩衝手段４０は、トリガーボディ１４の射出筒１４Ｃにおいてノズル２０（本実施形態ではノズル２０及び連結筒１９）が被着された部分の直近の後部で、該射出筒１４Ｃの上面の頂部を周方向で挟む２箇所のそれぞれに一体成形され、射出筒１４Ｃから突設されたリブ４１、４１にて構成される。リブ４１、４１は、該各リブ４１の中心線（射出筒１４Ｃから立上がるリブ４１の立上り方向に沿う中心軸線Ｌ（図２））が鉛直方向と一致しないように、射出筒１４Ｃから斜め上方に向けて突設される。各リブ４１はシュラウド３０の天面３２の内面に当接（又は微小間隙を介して対向）配置される。   The buffer means 40 is a rear portion of the injection cylinder 14C of the trigger body 14 in the vicinity of the portion where the nozzle 20 (in this embodiment, the nozzle 20 and the connecting cylinder 19) is attached, and the top of the upper surface of the injection cylinder 14C is circumferential. The ribs 41 and 41 are integrally formed at each of the two positions sandwiched between the ribs 41 and projecting from the injection cylinder 14C. The ribs 41 and 41 are obliquely above the injection cylinder 14C so that the center line of each rib 41 (the central axis L (FIG. 2) along the rising direction of the rib 41 rising from the injection cylinder 14C) does not coincide with the vertical direction. Projected toward Each rib 41 is disposed in contact with the inner surface of the top surface 32 of the shroud 30 (or opposed through a minute gap).

本参考例のリブ４１は、角棒状（丸棒状でも可）をなし、１つの側面（相対する２つの側面等、複数の側面でも可）の高さ方向（リブ４１の突設方向）の中間部の一部にＶ溝状の切欠を設けて形成された脆弱部４１Ａを備える。 The rib 41 of this reference example has a rectangular bar shape (or a round bar shape), and is intermediate in the height direction (the protruding direction of the rib 41) of one side surface (may be a plurality of side surfaces such as two opposite side surfaces). A fragile portion 41A formed by providing a V-groove notch in a part of the portion is provided.

尚、リブ４１は、図４、図５示す如く、トリガーボディ１４の射出筒１４Ｃの長手方向に沿って射出筒１４Ｃに突設される平板状をなすものでも良い。図４、図５のリブ４１は、相対する２つの側面の高さ方向の中間部の一部にＶ溝状の切欠を設けて形成された脆弱部４１Ａ、４１Ａを備える。   4 and 5, the rib 41 may have a flat plate shape protruding from the injection cylinder 14C along the longitudinal direction of the injection cylinder 14C of the trigger body 14. The rib 41 in FIGS. 4 and 5 includes fragile portions 41A and 41A formed by providing a V-groove notch in a part of the intermediate portion in the height direction of two opposing side surfaces.

尚、本発明において、「上側」、「上方」とは、トリガー式液体噴出器１０を設けた容器１１を水平面上に正立させたときの鉛直上方をいう。   In the present invention, “upper side” and “upper side” refer to a vertically upward direction when the container 11 provided with the trigger type liquid ejector 10 is erected on a horizontal plane.

本参考例によれば以下の作用がある。
(a)シュラウド３０は、トリガーボディ１４に支持される状態で、ノズル２０の上側を覆う。従って、トリガー式液体噴出器１０が内容液を収容した状態で逆さ向きに落下したときに、シュラウド３０に作用する衝撃荷重はトリガーボディ１４に及び、ノズル２０に及ぶことがない。衝撃荷重がノズル２０に及ばないから、ノズル２０の損傷を確実に防止できる。 According to this reference example , there are the following actions.
(a) The shroud 30 covers the upper side of the nozzle 20 while being supported by the trigger body 14. Therefore, when the trigger type liquid ejector 10 falls in the reverse direction while containing the content liquid, the impact load acting on the shroud 30 does not reach the trigger body 14 and the nozzle 20. Since the impact load does not reach the nozzle 20, damage to the nozzle 20 can be reliably prevented.

(b)シュラウド３０に作用する衝撃荷重は、緩衝手段４０を介してトリガーボディ１４に及ぶ。従って、衝撃荷重によるトリガーボディ１４の損傷も防止できる。 (b) The impact load acting on the shroud 30 reaches the trigger body 14 via the buffer means 40. Therefore, damage to the trigger body 14 due to impact load can be prevented.

(c)上述(b)の緩衝手段４０が脆弱部４１Ａ付きのリブ４１からなるものとすることにより、衝撃荷重の緩衝の確実を図ることができる。 (c) Since the buffer means 40 of (b ) described above includes the rib 41 with the weakened portion 41A, the shock load can be reliably buffered.

(d)リブ４１の中心線を鉛直方向と一致しないように設置したから、トリガー式液体噴出器１０が逆さ向きに落下したとき、シュラウド３０からリブ４１を介してボディ１４の射出筒１４Ｃに及ぶ力が小さくなり、射出筒１４Ｃに及ぼす衝撃荷重をより緩衝するものになる。 (d) Since the center line of the rib 41 is installed so as not to coincide with the vertical direction, when the trigger type liquid ejector 10 falls in the upside down direction, it extends from the shroud 30 to the injection cylinder 14C of the body 14 via the rib 41. The force is reduced, and the impact load exerted on the injection cylinder 14C is further buffered.

(e)シュラウド３０は、ノズル２０の周囲の全周に対し空隙Ｇを設ける。従って、シュラウド３０に作用する衝撃荷重がノズル２０に及ぶことを確実に回避し、ノズル２０の損傷を確実に防止できる。 (e) The shroud 30 provides a gap G for the entire circumference around the nozzle 20. Therefore, it is possible to reliably avoid the impact load acting on the shroud 30 from reaching the nozzle 20 and to prevent the nozzle 20 from being damaged.

図６はトリガー式液体噴出器１０の本発明例を示すものであり、この本発明例が前述した図１のものと異なる点は、緩衝手段４０をばね体５１により構成したことにある。即ち、緩衝手段４０は、図７に示す如く、トリガーボディ１４の射出筒１４Ｃにおいてノズル２０が被着された部分の直近の後部で、該射出筒１４Ｃの上面の頂部に一体成形され、射出筒１４Ｃから突設された片持ち状のばね体５１にて構成される。ばね体５１は射出筒１４Ｃからの突設方向（立上り方向）において湾曲部をもつ平板状をなす。ばね体５１はシュラウド３０の天面３２の内面に当接（又は微小間隙を介して対向）配置される。 Figure 6 shows a present invention example of the trigger type liquid ejector 10, is what differs from FIG. 1, the present invention example described above, in that the damping means 40 is constituted by a spring member 51. That is, as shown in FIG. 7, the buffer means 40 is integrally formed on the top of the upper surface of the injection cylinder 14C in the rear portion of the injection cylinder 14C of the trigger body 14 in the vicinity of the portion where the nozzle 20 is attached. It is comprised by the cantilever-like spring body 51 protrudingly provided from 14C. The spring body 51 has a flat plate shape having a curved portion in the projecting direction (rising direction) from the injection cylinder 14C. The spring body 51 is disposed in contact with the inner surface of the top surface 32 of the shroud 30 (or opposed via a minute gap).

尚、緩衝手段４０は、射出筒１４Ｃの上面の頂部を周方向で挟む２ヵ所のそれぞれに、２個のばね体５１、５１のそれぞれを一体成形するものでも良い。そして、ばね体５１、５１が、各ばね体５１の中心線が鉛直方向と一致しないように、射出筒１４Ｃから斜め上方に向けて突設されても良い。   The buffer means 40 may be formed by integrally molding each of the two spring bodies 51, 51 at each of two locations sandwiching the top of the upper surface of the injection cylinder 14C in the circumferential direction. Then, the spring bodies 51, 51 may be provided so as to project obliquely upward from the injection cylinder 14C so that the center line of each spring body 51 does not coincide with the vertical direction.

また、緩衝手段４０のばね体５１は、図８に示す如く、射出筒１４Ｃからの突設方向（立上り方向）において折れ曲がり部をもつ平板状をなすものでも良い。   Further, as shown in FIG. 8, the spring body 51 of the buffer means 40 may have a flat plate shape having a bent portion in the projecting direction (rising direction) from the injection cylinder 14C.

図６〜図８のトリガー式液体噴出器１０にあっても、緩衝手段４０がばね体５１からなるものとすることにより、衝撃荷重の緩衝の確実を図ることができる。 Even in the trigger type liquid ejector 10 of FIGS . 6 to 8, the shock absorbing means can be reliably buffered by the shock absorbing means 40 including the spring body 51.

尚、シュラウド３０はトリガーボディ１４と別部品化されず、一体成形されても良い。   Note that the shroud 30 may be integrally formed without being separated from the trigger body 14.

また、緩衝手段４０はトリガーボディ１４の側に設けられるものに限らず、シュラウド３０の側に設けられるものでも良い。   The buffer means 40 is not limited to the one provided on the trigger body 14 side, and may be provided on the shroud 30 side.

また、リブ４１、ばね体５１はトリガーボディ１４又はシュラウド３０に一体成形されても良く、トリガーボディ１４又はシュラウド３０と別部品化されてそれらのトリガーボディ１４、シュラウド３０に取付けられても良い。   Further, the rib 41 and the spring body 51 may be formed integrally with the trigger body 14 or the shroud 30, or may be separated from the trigger body 14 or the shroud 30 and attached to the trigger body 14 or the shroud 30.

また、緩衝手段４０は、リブ４１に限らず、ゴム、スポンジ等の弾性部材によって構成されても良い。   Further, the buffer means 40 is not limited to the rib 41 and may be constituted by an elastic member such as rubber or sponge.

本発明によれば、トリガー式液体噴霧器において、落下時のノズルの損傷を確実に防止することができる。   ADVANTAGE OF THE INVENTION According to this invention, damage to the nozzle at the time of dropping can be reliably prevented in a trigger type liquid sprayer.
