Description
【０００１】[0001]
本考案は液体注出容器に関する。 The present invention relates to a liquid dispensing container.
【０００２】[0002]
液体注出容器として、容器体口頚部外周に嵌合させた装着キャップと、該キャ ップにより容器体内に垂下させた吸い込み弁付きシリンダーと、該シリンダー内 に上方付勢状態で上下動可能に支持させ且つ下部にシリンダー内と連通する透孔 を穿設してなる吐出管上端に押し下げヘッドを固着してなる作動部材と、上記シ リンダー内面に外周縁を上下に摺動可能に嵌合させるとともに、上記吐出管外周 の上記透孔上方に周設したピストン押し下げ用突起及び上記透孔下方に周設した 外向きフランジ状係止突起間に上下動が可能に装着した環状ピストンとを有し、 上記環状ピストンの吐出弁体部下端と上記係止突起上面とで吐出弁を形成し、上 記作動部材の押し下げにより吸い込み弁が閉じるとともに、吐出弁が開いててシ リンダー内の液が吐出弁から上記透孔を通り押し下げヘッドの注出孔より注出さ れる如く構成したものが知られている（例えば、実開平２−４８１５９号に記載 された容器）。 As a liquid pouring container, a mounting cap fitted to the outer periphery of the neck of the container body, a cylinder with a suction valve hung down by the cap into the container body, and vertically movable in an upwardly biased state in the cylinder An operating member that is supported and has a through-hole that communicates with the inside of the cylinder at the bottom and has a push-down head fixed to the upper end of the discharge pipe, and the outer peripheral edge is slidably fitted to the inside of the cylinder above and below. At the same time, it has a piston-pushing projection provided around the through hole on the outer circumference of the discharge pipe and an annular piston mounted so as to be vertically movable between an outward flange-like locking projection provided around the through hole. A discharge valve is formed by the lower end of the discharge valve body of the annular piston and the upper surface of the locking projection, and the suction valve is closed by pushing down the above-mentioned actuating member, and the discharge valve opens and the liquid in the cylinder is closed. Those from the discharge valves were constructed as Notes issued from Note Deana head depressed through the hole is known (for example the container as described in the real-Open No. 2-48159).
【０００３】 この種容器では、作動部材の押し下げの際、環状ピストンが吐出管との間の摩 擦力で同時に下降してしまい当初吐出弁が開かない不都合が生じる場合がある。 この現象は、押し下げヘッドを下げた状態を続ければ、シリンダー内の液圧によ りピストンを押し上げて解消することは容易であるが、押し下げヘッドの上下動 は静止せずに行うのがこの種容器の用法として行き渡っており、使用者がポンプ の故障と間違える場合もあって好ましくない。特に、容器を開封して初めて使用 する場合、シリンダー内には空気が存在し、空気は液体より圧縮が容易であるた め使用中のシリンダー内へ液が充満している状態と比較してヘッドの押し下げ静 止をより長く必要とし、その結果故障との勘違いがより多くなる。In this type of container, when the actuating member is pushed down, the annular piston may simultaneously descend due to the frictional force between it and the discharge pipe, which may cause an inconvenience that the discharge valve does not initially open. This phenomenon can be easily resolved by pushing up the piston by the hydraulic pressure in the cylinder if the push-down head is kept down, but this type of movement is performed without stopping the push-down head up and down. It is widely used as a container, and it is not preferable because the user may mistake it for a pump failure. Especially when the container is opened and used for the first time, air is present in the cylinder, and since air is easier to compress than liquid, the head is compared with the state in which the cylinder is in use when liquid is full. It requires longer pressing down and stopping, resulting in more misunderstanding as failure.
【０００４】 本考案は上記した従来技術の欠点を解消した優れた液体注出容器を提案するも のである。The present invention proposes an excellent liquid pouring container which solves the above-mentioned drawbacks of the prior art.

【００２１】 本考案において、作動部材上昇位置では、環状ピストン９は図２に示す如く装 着キャップ３の嵌合筒部15下端に係止されるが、その状態における外部上方摺動 部9b下方に位置するシリンダー４内周面に、上方に行くに従って広がるテーパ状 の係止部32を周設している。通常環状ピストン９は、上昇状態の作動部材８を押 し下げた際、外部上方及び外部下方の各摺動部9b，9cとシリンダー内周面との摩 擦力で、吐出管６の垂下筒部26下端がピストン９上面と当接して押し下げる迄そ の位置に止まるが、内部上方摺動部9dと垂下筒部26内面の摩擦力が勝って作動部 材８と同時にピストン９が下降してしまった場合でも、上記係止部32により、図 ３に示す如くその外部上方摺動部9b上端が係止され、吐出弁31が間違いなく開く 様構成している。In the present invention, in the operating member raised position, the annular piston 9 is locked to the lower end of the fitting tubular portion 15 of the mounting cap 3 as shown in FIG. On the inner peripheral surface of the cylinder 4 located at, there is provided a taper-shaped locking portion 32 that widens as it goes upward. When the operating member 8 in the ascended state is pushed down, the normal annular piston 9 is rubbed by the sliding portions 9b, 9c on the upper and lower outer sides and the inner peripheral surface of the cylinder, so that the hanging cylinder of the discharge pipe 6 is lowered. The lower end of the part 26 comes into contact with the upper surface of the piston 9 and stops there until it is pushed down. Even if it does, the upper end of the outer upper sliding portion 9b is locked by the locking portion 32 as shown in FIG. 3, and the discharge valve 31 is surely opened.
【００２２】 尚、上記係止部32は、上記の如き上方に行くに従って広がるテーパ状をなすも のに限られず、リブ状の突起であっても良く、要は、ピストンが乗り越え可能で 且つピストンの係止が可能に構成した段差を有する係止部であればよい。The locking portion 32 is not limited to the tapered shape that widens as it goes upward as described above, and may be a rib-shaped projection. Any locking part having a step formed so as to be able to be locked may be used.
【００２３】 上記の如く構成した容器１は、押し下げヘッド７を押して作動部材８を下降さ せることにより、吐出管６の摺動突起24により吸い込み弁部材５が下降して吸い 込み弁20が閉じるとともに、環状ピストン９は吐出管の垂下筒部26下端がピスト ン上面を押圧するまで現状位置に止まるため吐出弁31が開きシリンダー４内が加 圧されてシリンダー４内の液が吐出弁31から透孔25を通り、吐出管６内より流通 路29を介してヘッド７の注出孔28より注出される。又、作動部材８の押圧を解除 すると、スプリング22の弾発力により作動部材８が上方に押し上げられ、それに 伴って吸い込み弁部材５が上方に引き上げられて吸い込み弁20が開き、又、吐出 弁31が閉じてシリンダー４内が負圧化して容器体２内の液がシリンダー４内に吸 い込まれる如く構成している。In the container 1 configured as described above, by pushing down the pushing head 7 to lower the operating member 8, the suction valve member 5 is lowered by the sliding projection 24 of the discharge pipe 6, and the suction valve 20 is closed. At the same time, the annular piston 9 stays at the current position until the lower end of the hanging tube portion 26 of the discharge pipe pushes the upper surface of the piston, so that the discharge valve 31 is opened and the inside of the cylinder 4 is pressurized so that the liquid in the cylinder 4 is discharged from the discharge valve 31. It passes through the through hole 25, and is discharged from the discharge hole 6 of the head 7 from the discharge pipe 6 through the flow path 29. When the pressing of the actuating member 8 is released, the actuating member 8 is pushed upward by the elastic force of the spring 22, the suction valve member 5 is pulled upward accordingly, and the suction valve 20 is opened. 31 is closed and the inside of the cylinder 4 becomes negative pressure so that the liquid in the container body 2 is sucked into the cylinder 4.
【００２４】 尚、上記各部材は全て合成樹脂により形成すると良い。It should be noted that all of the above members may be formed of synthetic resin.
【００２５】[0025]
以上説明した如く、本考案液体注出容器は既述構成としたことにより、作動部 材の押し下げに伴い確実に吐出弁が開き、従来のこの種の容器の如くポンプの故 障と間違われる虞がない優れたものである。 As described above, since the liquid pouring container of the present invention has the above-described configuration, the discharge valve is opened surely when the operating member is pushed down, which may be mistaken as a pump failure like the conventional container of this type. There is no excellent thing.
