Description

本発明は、プランジャーへの押圧によって内容液を噴出させるシリンジ型噴出容器に関するものである。 The present invention relates to a syringe-type ejection container that ejects content liquid by pressing a plunger.

従来、薬液等の内容液を噴出させるものとしては、例えば特許文献１に示されるような、シリンジ内に操作用のロッド（プランジャー）を押し込むようにしたものが一般的である。 Conventionally, as a method for ejecting a liquid content such as a chemical solution, for example, as shown in Patent Document 1, an operation rod (plunger) is generally pushed into a syringe.

特開平７−２１３６１２号公報JP 7-213612 A

ところで、内容液によっては、一度に全て噴出させずに所定の量を小分けにして噴出させることが望ましい場合がある。しかし、特許文献１に記載のようなシリンジ型噴出容器では、シリンジに示した目盛等を見ながら所定量を噴出させる必要があるため、正確な量で噴出させることが困難である上、操作に手間を要していた。 By the way, depending on the content liquid, it may be desirable to divide a predetermined amount into smaller portions without ejecting all at once.

本発明によれば、プランジャーの操作部に押圧力を付与すると、突起が第一押圧経路の終了端に至ったところでプランジャーの押し込みを一旦停止することができる。ここで第一押圧経路により案内される突起は、内向きガイド部によって回り止め保持された基体部に対して、プランジャーの軸線を周回する向きに移動するため、突起が第一押圧経路で案内されている間は、プランジャーの連結部が捩られることになる。一方、第一押圧経路の終了端には迂回経路が連結しているため、第一押圧経路の終了端に至った突起は、連結部の捩れを解消するように迂回経路の終了端まで移動する。迂回経路の終了端には第二押圧経路が連結しているため、操作部に押圧力を付与することで、突起が第二押圧経路の終了端に至る位置までプランジャーを押し込むことができる。このように本発明によれば、突起が第一押圧経路を移動する分と第二押圧経路を移動する分の少なくとも二回に分けて、内容液を噴出させることができる。また、一回目の噴出と二回目の噴出との間でプランジャーを特別に操作する必要がないため、噴出させる際の操作が簡単になる。 According to the present invention, when a pressing force is applied to the operation portion of the plunger, the pushing of the plunger can be temporarily stopped when the projection reaches the end of the first pressing path. Here, since the protrusion guided by the first pressing path moves in a direction to go around the axis of the plunger with respect to the base part held by the inward guide part, the protrusion is guided by the first pressing path. While being done, the connecting part of the plunger is twisted. On the other hand, since the bypass path is connected to the end of the first pressing path, the protrusion that reaches the end of the first pressing path moves to the end of the bypass path so as to eliminate the twist of the connecting portion. . Since the second pressing path is connected to the end of the detour path, the plunger can be pushed to a position where the protrusion reaches the end of the second pressing path by applying a pressing force to the operation portion. As described above, according to the present invention, it is possible to divide the content liquid into at least two times that the protrusion moves along the first pressing path and the movement along the second pressing path. Moreover, since it is not necessary to operate a plunger specially between the 1st ejection and the 2nd ejection, the operation at the time of ejecting becomes easy.

ピストンは抵抗を伴って押し込まれるため、プランジャーでピストンを押し込む際は、プランジャーの軸線に沿う押圧力が弾性部に付与されて、弾性部が突起を径方向外側に押し出すように変形する。ここで、迂回経路に、シリンジの内周面と外周面とを連通させた孔によって形成される迂回経路開始部と、迂回経路開始部に連続するとともにシリンジの内周面を外周面側に凹ませた溝によって形成される迂回経路終了部とを設ける場合、第一押圧経路の終了端（迂回経路の開始端）に至った突起は、弾性部の変形によって、迂回経路開始部の孔に挿通されるように径方向外側に移動することになる。一方、迂回経路終了部は溝になっていて、迂回経路開始部と迂回経路終了部との境界は、径方向内側に向かって凸となる段部となっている。このため、この段部によって迂回経路の終了端へ向かう突起の移動が妨げられるため、二回目の噴出が不用意に行われるおそれがなくなる。なお、一回目の噴出操作の直後に残った弾性部の変形は、ピストンの抵抗力や弾性部の復元力を適宜調整することにより、ピストンを所定の位置まで前進させるようにして徐々に解消することも、また、操作部への押圧を一旦緩めて操作部を後端側へ僅かに戻すようにして解消することも可能である。これにより突起が径方向内側に戻るため、連結部の捩れの解消に伴って、突起は迂回経路の終了端まで自動的に移動する。 Since the piston is pushed with resistance, when the piston is pushed by the plunger, a pressing force along the axis of the plunger is applied to the elastic portion, and the elastic portion is deformed so as to push the protrusion outward in the radial direction. Here, a detour path start portion formed by a hole that connects the inner peripheral surface and the outer peripheral surface of the syringe to the detour path, and the inner peripheral surface of the syringe that is continuous with the detour path start portion and recessed toward the outer peripheral surface side. When the end of the detour path formed by the groove is provided, the protrusion reaching the end of the first pressing path (the start end of the detour path) is inserted into the hole of the detour path start by deformation of the elastic portion. It moves to the radial direction outer side. On the other hand, the detour route end portion is a groove, and the boundary between the detour route start portion and the detour route end portion is a stepped portion that protrudes radially inward. For this reason, since the movement of the projection toward the end of the detour path is prevented by this stepped portion, there is no possibility that the second ejection is inadvertently performed. The deformation of the elastic portion remaining immediately after the first ejection operation is gradually eliminated by appropriately adjusting the resistance force of the piston and the restoring force of the elastic portion so as to advance the piston to a predetermined position. In addition, it is also possible to solve the problem by once releasing the pressure on the operation unit and slightly returning the operation unit to the rear end side. As a result, the protrusion returns to the inner side in the radial direction, so that the protrusion automatically moves to the end of the detour path as the twist of the connecting portion is eliminated.

第一押圧経路に、シリンジの内周面を外周面側に凹ませた溝によって形成される第一押圧経路開始部と、第一押圧経路開始部に連続するとともにシリンジの内周面と外周面とを連通させた孔によって形成される第一押圧経路終了部とを設け、第二押圧経路に、シリンジの内周面を外周面側に凹ませた溝によって形成される第二押圧経路開始部と、第二押圧経路開始部に連続するとともにシリンジの内周面と外周面とを連通させた孔によって形成される第二押圧経路終了部とを設ける場合は、弾性部の変形によって径方向外側に押し出される突起に対し、溝では抵抗が加わり、孔ではその抵抗が解消されることになる。すなわち、一回目及び二回目の何れの噴出においても、プランジャーを、押圧力の付与直後から暫くの間はゆっくり移動させ、その後は急速に移動させることができるので、内容液を、蓄圧（圧縮）された状態から瞬時に開放されたような状態にして噴出させることができる。 A first pressing path start portion formed by a groove in which the inner peripheral surface of the syringe is recessed toward the outer peripheral surface side in the first pressing path, and an inner peripheral surface and an outer peripheral surface of the syringe that are continuous with the first pressing path start portion. And a second pressing path start portion formed by a groove in which the inner peripheral surface of the syringe is recessed on the outer peripheral surface side in the second pressing path. And a second pressing path end portion formed by a hole that is continuous with the second pressing path start portion and communicates the inner peripheral surface and the outer peripheral surface of the syringe. Resistance is applied to the protrusion pushed out by the groove, and the resistance is eliminated at the hole. That is, in both the first and second ejections, the plunger can be moved slowly for a while immediately after the pressing force is applied, and then rapidly moved. ) Can be ejected in such a state that it is released instantly.

迂回経路の終了端と前記第一押圧経路の開始端とをつなぐ帰還経路を、シリンジの軸線に沿って延在するとともにシリンジの内周面を外周面側に凹ませた溝によって形成し、帰還経路の内周面を、迂回経路の終了端から第一押圧経路の開始端に向かって径方向内側に傾く傾斜面として設ける場合は、使用済みの噴出部を新たな噴出部に取り換えるに当たり、プランジャーを第一押圧経路の開始端に戻す際にプランジャーをスムーズに引き戻すことができ、突起が傾斜面を乗り越える感触により初期位置に引き戻されたことを確認できる。 A return path that connects the end of the detour path and the start of the first pressing path is formed by a groove extending along the axis of the syringe and having the inner peripheral surface of the syringe recessed toward the outer peripheral surface. When the inner peripheral surface of the route is provided as an inclined surface that is inclined inward in the radial direction from the end of the detour route toward the start of the first pressing route, the plan is to replace the used jet part with a new jet part. When returning the jar to the start end of the first pressing path, the plunger can be pulled back smoothly, and it can be confirmed that the protrusion has been pulled back to the initial position by the feeling of getting over the inclined surface.

A second pressing path end portion that is formed by a hole that is continuous with the starting portion 40a and the second pressing path starting portion 40a and extends to the end Kd thereof and that communicates the inner peripheral surface and the outer peripheral surface of the syringe 30. 40b.

更に、図５、図９に示すように、迂回経路３９の終了端Ｋｃと第一押圧経路３８の開始端Ｋａとは、帰還経路４１でつながっている。帰還経路４１は、軸線Ｍに沿って延在するとともにシリンジ３０の内周面を外周面側に凹ませた溝によって形成されている。また、帰還経路４１の内周面には、迂回経路３９の終了端Ｋｃから第一押圧経路３８の開始端Ｋａに向かって径方向内側に傾く傾斜面４１ａが形成されている。 Further, as shown in FIGS. 5 and 9, the end end Kc of the detour path 39 and the start end Ka of the first pressing path 38 are connected by a return path 41. The return path 41 is formed by a groove extending along the axis M and having the inner peripheral surface of the syringe 30 recessed on the outer peripheral surface side. In addition, an inclined surface 41 a is formed on the inner peripheral surface of the return path 41, which is inclined radially inward from the end end Kc of the detour path 39 toward the start end Ka of the first pressing path 38.

図１０に示すようにプランジャー５０は、先端側に設けられる円柱状の先端軸５１と、円柱状をなすとともにその中央部にトラック状の孔５２が設けられ、先端軸５１に連結する弾性部５３と、弾性部５３の外周面に設けられ、径方向外側に向けて突出する円柱状の突起５４と、横断面が弾性部５３よりも小さく形成される矩形状であって、弾性部５３に連結する連結部５５と、横断面が連結部５５よりも大きく形成される円柱状であって、連結部５５に連結する基体部５６と、基体部５６の外周面に設けられ、プランジャー５０の軸線Ｎに沿って延在するリブ状の外向きガイド部５７と、基体部５６の後端側に連結するフランジ状の操作部５８とを備えている。 As shown in FIG. 10, the plunger 50 has a cylindrical tip shaft 51 provided on the tip side, and a cylindrical portion and a track-shaped hole 52 provided in the center thereof, and an elastic portion connected to the tip shaft 51. 53, a cylindrical protrusion 54 provided on the outer peripheral surface of the elastic portion 53 and projecting radially outward, and a rectangular shape having a transverse section smaller than that of the elastic portion 53. A connecting portion 55 to be connected, a columnar cross section formed larger than the connecting portion 55, a base portion 56 connected to the connecting portion 55, and provided on the outer peripheral surface of the base portion 56, A rib-like outward guide portion 57 extending along the axis N and a flange-like operation portion 58 connected to the rear end side of the base portion 56 are provided.

プランジャー５０に対して、弾性部５３と基体部５６との間で軸線Ｎを周回する向きにひねりを加えると、他の部位よりも剛性が小さくなる連結部５５が捩られることになる。また、弾性部５３に対して軸線Ｎに沿って押圧力が付与されると、図１１に示すように弾性部５３が径方向外側に広がるように変形し、突起５４が径方向外側に移動する。 When a twist is applied to the plunger 50 in the direction of circling the axis N between the elastic portion 53 and the base portion 56, the connecting portion 55 having lower rigidity than other portions is twisted. When a pressing force is applied to the elastic portion 53 along the axis N, the elastic portion 53 is deformed so as to spread radially outward as shown in FIG. 11, and the protrusion 54 moves radially outward. .

上記のように構成されるシリンジ型噴出容器から内容液Ｆを噴出させるに当たっては、プランジャー５０の突起５４及び外向きガイド部５７を、シリンジ３０の導入経路３６及び内向きガイド部３５に位置合わせする。そして、プランジャー５０をシリンジ３０の後端側から挿通し、図４に示すように、突起５４が凸部３６ａを乗り越えるまで移動させる。なおこの位置は、図５に示す第一押圧経路３８の開始端Ｋａに対応する。また、この位置においてプランジャー５０の先端軸５１は、図１に示すようにその先端部が、シリンジ３０の先端筒部３２から突出するように形成されている。 When ejecting the content liquid F from the syringe-type ejection container configured as described above, the protrusion 54 and the outward guide portion 57 of the plunger 50 are aligned with the introduction path 36 and the inward guide portion 35 of the syringe 30. To do. Then, the plunger 50 is inserted from the rear end side of the syringe 30 and is moved until the projection 54 gets over the convex portion 36a as shown in FIG. This position corresponds to the start end Ka of the first pressing path 38 shown in FIG. Further, at this position, the distal end shaft 51 of the plunger 50 is formed such that its distal end protrudes from the distal end cylindrical portion 32 of the syringe 30 as shown in FIG.

次いで、パイプ部材２１を先端筒部３２に挿入しつつ回転させ、フランジ部２１ｃを装着筒部３３のねじ部３３ａに係合させて、噴出部２０をシリンジ３０の先端側に保持する。この状態においてピストン２５は、その後端が先端軸５１の先端に対して僅かに隙間をあけるか、先端軸５１によって押し込まれる状態となっている。 Next, the pipe member 21 is rotated while being inserted into the distal end cylindrical portion 32, and the flange portion 21 c is engaged with the threaded portion 33 a of the mounting cylindrical portion 33, thereby holding the ejection portion 20 on the distal end side of the syringe 30. In this state, the piston 25 is in a state where its rear end is slightly spaced from the tip of the tip shaft 51 or pushed by the tip shaft 51.

その後は、カバー２４を取り外し、例えば人差し指と中指をシリンジ３０の指掛け部３４に掛けるとともにプランジャー５０の操作部５８に親指を当てがい、プランジャー５０を先端側に向けて押圧する（内容液の一回目の噴出）。 After that, the cover 24 is removed, and for example, the index finger and the middle finger are put on the finger-hanging portion 34 of the syringe 30 and the thumb is placed on the operation portion 58 of the plunger 50 to press the plunger 50 toward the tip side (the content liquid First eruption).

内容液の一回目の噴出の際、突起５４は第一押圧経路３８に案内される。図５〜図７に示すように第一押圧経路３８には、溝によって形成される第一押圧経路開始部３８ａと、孔によって形成される第一押圧経路終了部３８ｂとが設けられている。ここで、プランジャー５０の押圧によって押し込まれるピストン２５は、大径部２１ｂとの間で生じる摺動抵抗や、内容液Ｆが内部通路Ｔ１等を通る際の流動抵抗を伴って移動することになるため、弾性部５３には押圧力が加わることになる。このため、弾性部５３は図１１に示すように変形し、突起５４は径方向外側に向けて押し出される。これにより、突起５４が第一押圧経路開始部３８ａを通過する際には、溝の内周面に突起５４が当接して抵抗が加わる一方、第一押圧経路終了部３８ｂを通過する際には、その抵抗が解消されることになる。このためプランジャー５０を、押圧力の付与直後から暫くはゆっくり移動させ、その後は急速に移動させることができるので、内容液Ｆを、蓄圧（圧縮）された状態から瞬時に開放されたような状態にして噴出させることができる。 When the content liquid is ejected for the first time, the protrusion 54 is guided to the first pressing path 38. As shown in FIGS. 5-7, the 1st press path | route 38 is provided with the 1st press path | route start part 38a formed with a groove | channel, and the 1st press path | route end part 38b formed with a hole. Here, the piston 25 pushed by the pressing of the plunger 50 moves with sliding resistance generated between the large diameter portion 21b and flow resistance when the content liquid F passes through the internal passage T1 and the like. Therefore, a pressing force is applied to the elastic portion 53. Therefore, the elastic portion 53 is deformed as shown in FIG. 11, and the protrusion 54 is pushed out radially outward. Thereby, when the projection 54 passes through the first pressing path start portion 38a, the projection 54 comes into contact with the inner peripheral surface of the groove to add resistance, while when the projection 54 passes through the first pressing path end portion 38b. That resistance will be eliminated. For this reason, since the plunger 50 can be moved slowly for a while immediately after the application of the pressing force, and then can be moved rapidly thereafter, the content liquid F seems to be released instantaneously from the accumulated (compressed) state. Can be ejected in a state.

突起５４が第一押圧経路３８に案内される間、プランジャー５０の基体部５６は、外向きガイド部５７と連係する内向きガイド部３５によって回り止め保持されているため、弾性部５３と基体部５６の間には、軸線Ｍを周回する向きにひねりの力が加わることになる。これにより連結部５５は、捩られた状態になっている。ここで、突起５４が第一押圧経路３８の終了端（迂回経路３９の開始端）Ｋｂに達すると、ここには迂回経路３９が設けられているため、連結部５５の捩れを戻す作用によって、突起５４を迂回経路３９の終了端Ｋｃに向けて移動させることができる。但し本実施形態では、二回目の噴出が不用意に行われないようにするため、図５、図８に示すように、孔によって形成される迂回経路開始部３９ａと、溝によって形成される迂回経路終了部３９ｂと設け、迂回経路開始部３９ａと迂回経路終了部３９ｂとの境界に形成される、径方向内側に向かって凸となる段部ｄによって、突起５４の移動を制限している。なお、一回目の噴出操作の直後に残った弾性部５３の変形は、ピストン２５の抵抗力や弾性部５３の復元力を適宜調整することにより、ピストン２５を所定の位置まで前進させるようにして徐々に解消することも、また、操作部５８への押圧を一旦緩めて操作部５８を後端側へ僅かに戻すようにして解消することも可能である。これにより突起５４が径方向内側に戻るため、連結部５５の捩れを復元させることが可能となり、迂回経路３９の終了端Ｋｃまで突起５４が自動的に移動する。 While the protrusion 54 is guided to the first pressing path 38, the base portion 56 of the plunger 50 is held and prevented by the inward guide portion 35 linked to the outward guide portion 57. A twisting force is applied between the portions 56 in the direction of circling the axis M. Thereby, the connection part 55 is in the twisted state. Here, when the protrusion 54 reaches the end end (start end of the detour path 39) Kb of the first pressing path 38, since the detour path 39 is provided here, the action of returning the torsion of the connecting portion 55, The protrusion 54 can be moved toward the end Kc of the detour path 39. However, in the present embodiment, in order to prevent the second ejection from being inadvertently performed, as shown in FIGS. 5 and 8, as shown in FIGS. 5 and 8, the detour route start portion 39 a formed by the hole and the detour formed by the groove The movement of the projection 54 is limited by a step d provided on the boundary between the detour path start section 39a and the detour path end section 39b, which is provided in the path end section 39b and protrudes inward in the radial direction. The deformation of the elastic portion 53 remaining immediately after the first ejection operation is performed by appropriately adjusting the resistance force of the piston 25 and the restoring force of the elastic portion 53 so that the piston 25 is advanced to a predetermined position. It is also possible to eliminate gradually, or to release the operation portion 58 by slightly releasing the pressure on the operation portion 58 and slightly returning the operation portion 58 to the rear end side. As a result, the protrusion 54 returns to the inner side in the radial direction, so that the torsion of the connecting portion 55 can be restored, and the protrusion 54 automatically moves to the end end Kc of the detour path 39.

その後、操作部５８を再度押圧することでプランジャー５０が押し込まれ（突起５４は、
第二押圧経路４０の開始端Ｋｃから終了端Ｋｄまで移動する）、二回目の噴出を行うことができる。なお、図５、図９に示すように第二押圧経路４０には、溝によって形成される第二押圧経路開始部４０ａと、孔によって形成される第二押圧経路終了部４０ｂとが形成されているので、一回目の噴出と同様に、内容液Ｆを、蓄圧（圧縮）された状態から瞬時に開放されたような状態にして噴出させることができる。 Thereafter, the plunger 50 is pushed by pressing the operation portion 58 again (the projection 54 is
The second pressing path 40 moves from the start end Kc to the end end Kd), and the second ejection can be performed. As shown in FIGS. 5 and 9, the second pressing path 40 includes a second pressing path start portion 40 a formed by a groove and a second pressing path end portion 40 b formed by a hole. Therefore, similarly to the first ejection, the content liquid F can be ejected in a state where it is instantaneously released from the accumulated (compressed) state.

本実施形態の噴出部２０は、シリンジ３０に対して着脱自在に装着されるものであって、内容液Ｆを噴出した後は新たな噴出部２０に取り換えることで、シリンジ３０、プランジャー５０を再利用することができる（噴出部２０をカートリッジとして用いている）。新たな噴出部２０をシリンジ３０に装着するに当たっては、第二押圧経路４０の終了端Ｋｄに位置する突起５４を、第一押圧経路３８の開始端Ｋａに戻す必要があるが、本実施形態では、図５、図９に示すように、第二押圧経路４０の開始端（迂回経路３９の終了端）Ｋｃと第一押圧経路３８の開始端Ｋａとを帰還経路４１でつないでいるので、プランジャー５０を後端側へ引き戻すだけで、突起５４を第一押圧経路３８の開始端Ｋａに戻すことができる。なお、帰還経路４１の内周面には傾斜面４１ａが形成されているので、突起５４が途中で引っ掛かることがない。このため、プランジャー５０をスムーズに引き戻すことができる。 The ejection part 20 of this embodiment is detachably attached to the syringe 30, and after ejecting the content liquid F, the ejection part 20 is replaced with a new ejection part 20, whereby the syringe 30 and the plunger 50 are replaced. It can be reused (the ejection part 20 is used as a cartridge). In attaching the new ejection part 20 to the syringe 30, it is necessary to return the protrusion 54 positioned at the end Kd of the second pressing path 40 to the starting end Ka of the first pressing path 38. 5 and FIG. 9, the return path 41 connects the start end (end end of the detour path 39) Kc of the second press path 40 and the start end Ka of the first press path 38. The projection 54 can be returned to the start end Ka of the first pressing path 38 simply by pulling the jar 50 back to the rear end side. In addition, since the inclined surface 41a is formed in the inner peripheral surface of the return path 41, the protrusion 54 is not caught on the way. For this reason, the plunger 50 can be pulled back smoothly.

本発明に従うシリンジ型噴出容器は、本実施形態に限定されるものではなく、特許請求の範囲に従う範囲で種々の変更が可能である。例えば噴出部２０は、シリンジ３０のねじ部３３ａで保持されるようにしたが、ねじ部３３ａに代えてアンダーカットを設け、このアンダーカットに係合されるようにしてもよい。また、噴出部２０のスピンエレメント２２に代えてメッシュを設けることで、内容液を泡状にして噴出させることもできる。また、本実施形態では内容液を二回に小分けして噴出させるようにしたが、第一押圧経路３８や迂回経路３９等の数を増やし、これらを繰り返し設けることで、３回以上に小分けして噴出させることも可能である。仮に、３回に小分けして噴出させるべく、第一押圧経路及び迂回経路を合計２個設ける場合、第一押圧経路におけるシリンジの軸線を周回する向きへの傾斜は、一つ目と二つ目とで逆方向に周回するようにすることも可能である。更に、孔として形成した第一押圧経路終了部、迂回経路開始部、及び第二押圧経路終了部を、溝部として形成した第一押圧経路開始部、迂回経路終了部、及び第二押圧経路開始部よりも深さが深い溝（外周面側に向かってより凹む溝）として形成してもよい。 The syringe-type ejection container according to the present invention is not limited to this embodiment, and various modifications can be made within the scope according to the claims. For example, the ejection portion 20 is held by the screw portion 33a of the syringe 30, but an undercut may be provided instead of the screw portion 33a and engaged with the undercut. Further, by providing a mesh instead of the spin element 22 of the ejection part 20, the content liquid can be ejected in the form of foam. Further, in the present embodiment, the content liquid is subdivided into two portions and ejected. However, by increasing the number of the first pressing path 38, the detour path 39, etc., and repeatedly providing them, the content liquid is subdivided into three or more times. It is also possible to erupt. If a total of two first pressing paths and detour paths are provided in order to divide into three sub-jets, the first and second inclinations in the direction of circling the syringe axis are the first and second. It is also possible to go around in the opposite direction. Furthermore, the first pressing path end part, the detour path starting part, and the second pressing path end part formed as holes, the first pressing path start part, the detour path end part, and the second pressing path start part formed as grooves. It may be formed as a groove having a deeper depth (a groove that is more concave toward the outer peripheral surface side).

本発明によれば、内容液を小分けにして所定の量で噴出することができるとともに、小分けして噴出する間でプランジャーを特別に操作する必要がないため、噴出させる際の操作が簡単になる、新規のシリンジ型噴出容器を提供することができる。 According to the present invention, the content liquid can be subdivided and ejected in a predetermined amount, and since there is no need to specially operate the plunger during the subdivided ejection, the operation at the time of ejection is simple. Thus, a novel syringe-type ejection container can be provided.
