　液体入りスポイト容器１２は、例えば、以下に説明する本実施の形態に係る液体入りスポイト容器の製造方法によって製造することができる。なお、本実施の形態に係る液体入りスポイト容器の製造方法は、液体入りスポイト容器１２の上述した種々の変形例を製造する場合にも適用可能である。 The liquid dropper container 12 can be manufactured, for example, by the method for manufacturing a liquid dropper container according to the present embodiment described below. The method for manufacturing a liquid dropper container according to the present embodiment can also be applied to the case of manufacturing various modifications of the liquid dropper container 12 described above.
　本実施の形態に係る液体入りスポイト容器の製造方法は、液室形成工程と、図２に示す液室充填工程と、図４に示すスポイトキャップ形成工程と、容器本体充填工程と、図５に示すスポイトキャップ取付工程とを有している。 The method for manufacturing the liquid dropper container according to the present embodiment includes a liquid chamber forming step, a liquid chamber filling step shown in FIG. 2, a dropper cap forming step shown in FIG. 4, a container body filling step, and FIG. It has the dropper cap mounting process shown.
　液室形成工程は、外筒５のシール部２３をノズル部材６の外周面に設けられた弾性部材６ｂに密接させることで液室１１を形成する工程である。液室形成工程が終了すると、液室充填工程が行われる。 The liquid chamber forming step is a step of forming the liquid chamber 11 by bringing the sealing portion 23 of the outer cylinder 5 into close contact with the elastic member 6b provided on the outer peripheral surface of the nozzle member 6. When the liquid chamber forming step is completed, the liquid chamber filling step is performed.
　図２に示すように、液室充填工程は、例えば充填ノズル２５を用いて、液室１１内に液体Ｌ１を充填する工程である。充填ノズル２５は、ノズル２１の上端を閉塞する底部２５ａと、外筒５の上端に密接する円筒状の外周壁２５ｂと、外周壁２５ｂと底部２５ａとを連結するとともに周方向に間隔を空けて並ぶ複数の連結片２５ｃとを有している。液体Ｌ１は、外周壁２５ｂ内を流れ落ち、複数の連結片２５ｃの隙間と間欠フランジ２２の間欠部とを通り、液室１１内に充填される。なお、外周壁２５ｂには空気抜き用の複数の孔２５ｄが設けられている。充填ノズル２５の構成はこれに限らず、例えば、複数の連結片２５ｃに代えて、図３に示すように複数の貫通孔２５ｅを有する円筒状の連結壁２５ｆを有する構成であってもよい。 As shown in FIG. 2, the liquid chamber filling step is a step of filling the liquid chamber 11 with the liquid L1 using, for example, a filling nozzle 25. The filling nozzle 25 connects the bottom portion 25a that closes the upper end of the nozzle 21, the cylindrical outer peripheral wall 25b that is in close contact with the upper end of the outer cylinder 5, and the outer peripheral wall 25b and the bottom portion 25a, and is spaced apart in the circumferential direction. It has a plurality of connecting pieces 25c arranged side by side. The liquid L1 flows down the outer peripheral wall 25b, passes through the gaps between the plurality of connecting pieces 25c and the intermittent portion of the intermittent flange 22, and is filled in the liquid chamber 11. The outer peripheral wall 25b is provided with a plurality of holes 25d for venting air. The configuration of the filling nozzle 25 is not limited to this, and may be, for example, a configuration having a cylindrical connecting wall 25f having a plurality of through holes 25e as shown in FIG. 3 instead of the plurality of connecting pieces 25c.
　液室充填工程が終了すると、スポイトキャップ形成工程が行われる。図４に示すように、スポイトキャップ形成工程は、液室１１内に液体Ｌ１が収容された状態でノズル部材６に吸上げキャップ部材７を取付ることで、スポイト３を備えるスポイトキャップ４を形成する工程である。なお、スポイト３は、吸上げ部材９の吸上げ部３ａと、ジョイント部材１０の上筒１７、下フランジ１６の内周縁及び連結筒１８と、ノズル部材６とで形成される。このようにスポイトキャップ４が形成されたとき、接触筒２０が外筒５に密接することにより、外筒５がスポイトキャップ４から抜け落ちることや、液室１１内から液体Ｌ１がこぼれることが防止される。しかし、上述したとおり、接触筒２０を設けない構成としてもよい。 When the liquid chamber filling process is completed, the dropper cap forming process is performed. As shown in FIG. 4, in the dropper cap forming step, the dropper cap 4 including the dropper 3 is formed by attaching the suction cap member 7 to the nozzle member 6 in a state where the liquid L1 is housed in the liquid chamber 11. It is a process to do. The dropper 3 is formed by a suction portion 3a of the suction member 9, an upper cylinder 17 of the joint member 10, an inner peripheral edge of the lower flange 16, a connecting cylinder 18, and a nozzle member 6. When the dropper cap 4 is formed in this way, the contact cylinder 20 comes into close contact with the outer cylinder 5 to prevent the outer cylinder 5 from falling out of the dropper cap 4 and the liquid L1 from spilling from the inside of the liquid chamber 11. To. However, as described above, the contact cylinder 20 may not be provided.
　スポイトキャップ形成工程が終了すると、スポイトキャップ取付工程が行われる。また、スポイトキャップ取付工程に先立つ所望のタイミングで容器本体充填工程が行われる。容器本体充填工程は、容器本体２内に他の液体Ｌ２を充填する工程である。図５に示すように、スポイトキャップ取付工程は、液室１１内に液体Ｌ１が収容されるとともに容器本体２内に他の液体Ｌ２が収容された状態で容器本体２の口部２ａにスポイトキャップ４を取付ることで、外筒５の取付部２４を口部２ａに取付る工程である。スポイトキャップ取付工程が終了し、完成した液体入りスポイト容器１２が図１に示されている。 When the dropper cap forming process is completed, the dropper cap mounting process is performed. Further, the container body filling step is performed at a desired timing prior to the dropper cap mounting step. The container body filling step is a step of filling the container body 2 with another liquid L2. As shown in FIG. 5, in the dropper cap attaching step, the dropper cap is housed in the mouth portion 2a of the container body 2 in a state where the liquid L1 is housed in the liquid chamber 11 and the other liquid L2 is housed in the container body 2. This is a step of attaching the attachment portion 24 of the outer cylinder 5 to the mouth portion 2a by attaching the 4. FIG. 1 shows the completed liquid-containing dropper container 12 after the dropper cap mounting process is completed.
　本実施の形態に係る液体入りスポイト容器の製造方法によれば、液体入りスポイト容器１２を単純な工程によって製造することができる。しかし、液体入りスポイト容器１２及び上述した種々の変形例は、上述した方法以外の製造方法によって製造してもよい。 According to the method for manufacturing a liquid dropper container according to the present embodiment, the liquid dropper container 12 can be manufactured by a simple process. However, the liquid-containing dropper container 12 and the various modifications described above may be manufactured by a manufacturing method other than the above-mentioned method.
　液体入りスポイト容器１２は、図１に示すようにスポイトキャップ４が口部２ａに取付られ、液体Ｌ１と他の液体Ｌ２とが別々に収容された状態で流通、保管される。また、その使用開始に際しては、図６に示すように、口部２ａからスポイトキャップ４を取外すだけの少ない手間で、口部２ａに残った外筒５のシール部２３とスポイトキャップ４の弾性部材６ｂとの密接が解消して液室１１の底部が開放され、液体Ｌ１と他の液体Ｌ２との混合が許容される。液体Ｌ１と他の液体Ｌ２との混合後は、ノズル部材６の下端を外筒５内の液面に浸けて吸上げ部３ａを押圧操作し、ノズル部材６内に液体を吸上げ、所望の場所に滴下することができる。 As shown in FIG. 1, the liquid-containing dropper container 12 has a dropper cap 4 attached to the mouth portion 2a, and is distributed and stored in a state where the liquid L1 and the other liquid L2 are separately contained. Further, at the start of use thereof, as shown in FIG. 6, the elastic member of the seal portion 23 of the outer cylinder 5 and the dropper cap 4 remaining in the mouth portion 2a requires little effort to remove the dropper cap 4 from the mouth portion 2a. The close contact with 6b is eliminated, the bottom of the liquid chamber 11 is opened, and mixing of the liquid L1 with the other liquid L2 is allowed. After mixing the liquid L1 and the other liquid L2, the lower end of the nozzle member 6 is immersed in the liquid surface in the outer cylinder 5 and the suction portion 3a is pressed to suck the liquid into the nozzle member 6, which is desired. Can be dropped in place.
