Description

本発明は、内容液を少量ずつ吐出口より吐出させることができる少量吐出容器に関する。   The present invention relates to a small-volume discharge container capable of discharging a content liquid from a discharge port little by little.

点眼薬やうがい薬などを収納した容器には、少量ずつ内容液を吐出させる少量吐出容器が用いられている。このような少量吐出容器は、例えば吐出容器の胴部に、胴部を軸方向に収縮させる変形部を設け、容器全体を軸方向に収縮させることにより、内部の圧力を高め吐出口から数滴の内容液を滴下させるようにしている。   For containers containing eye drops or mouthwashes, a small volume discharge container that discharges a small amount of content liquid is used. In such a small amount discharge container, for example, a deformed part that contracts the body part in the axial direction is provided in the body part of the discharge container, and the entire container is contracted in the axial direction, thereby increasing the internal pressure and several drops from the discharge port. The content liquid is dripped.

また筒状のカバーの内部にボトルを組み入れ、ボトルを底部から押圧してカバーの内部に押し込み、ボトル内に収納された内容液を少量ずつ、カバーに設けられた吐出口より吐出させる吐出容器も知られている。   There is also a discharge container that incorporates a bottle into the cylindrical cover, presses the bottle from the bottom and pushes it into the cover, and discharges the liquid contained in the bottle from the discharge port provided in the cover little by little. Are known.

特開２００４−５１１６５号公報JP 2004-511165 A

しかしながら上記従来の少量吐出容器は、吐出容器全体を握り、胴部を軸方向に変形させる必要があり、使い勝手に問題があった。しかも、吐出容器全体を片手で握れる大きさ、形状にしなければならず、容量、容器のデザインの面で自由度が低かった。   However, the conventional small-volume discharge container has a problem in usability because it is necessary to grip the entire discharge container and to deform the body part in the axial direction. Moreover, the entire discharge container must be sized and shaped so that it can be grasped with one hand, and the degree of freedom in terms of capacity and container design has been low.

またカバーを容器外周に設けた構成は、カバーと容器の内部構造が複雑となり、部品点数が多くなり、吐出容器の成形、組み立て工程に手間がかかるという問題があった。   In addition, the configuration in which the cover is provided on the outer periphery of the container has a problem that the internal structure of the cover and the container is complicated, the number of parts is increased, and the molding and assembling process of the discharge container is troublesome.

本発明は、使い勝手やデザインがよく、しかも部品点数が少なく、構造が簡易で、組み付け工程が簡略化された少量吐出容器を提供することを目的とする。   An object of the present invention is to provide a small-volume discharge container that has good usability and design, has a small number of parts, has a simple structure, and has a simplified assembly process.

本発明は上記課題を解決するため、少量吐出容器を次のように構成した。   In order to solve the above-mentioned problems, the present invention is configured as follows.

１、内容液を有底筒状のボトル内に収納し、ボトルをカバー内部に軸方向に往復動可能に組み入れた少量吐出容器において、
カバーは、前端に吐出口を具え、後端の周縁に、指の腹を押し入れる切り欠きを有し、

ボトルの口部内周に組み付く組付筒体と、組付筒体の上方に設けられ、案内筒体の内周面に液密に、かつ摺動自在に挿入されるバルブ体とからなるボトル中栓が前記ボトルの口部内周に組み付き、
ボトルの口部外周に組み付くキャップ筒体と、キャップ筒体の頂壁中央に設けられ、案内筒体の外周面に摺動自在に嵌め合わされる摺動筒体とからなるボトルキャップが、摺動筒体の内部にバルブ体を通してボトルの口部外周に組み付き、
摺動筒体の外方で、仕切壁と頂壁の間にばねを配置してボトルとカバーが往復動可能に組み付き、
ばねの反力に抗してボトルをカバー前方に押し込むと、バルブ体による流出口の閉鎖が解除され、吐出口より内容液が吐出するように少量吐出容器を構成した。
２、 案内筒体の内面に、流出口の縁から案内筒体の軸方向に沿って後方に延びる溝部を形成し、バルブ体が溝部の位置に移動すると流出口の閉鎖が解除されることとして少量吐出容器を構成した。
３、 栓体の外周面を所定形状に形成し、栓体の外周面と吐出口の内周面との間に内容液を浸出させる間隙を設けて少量吐出容器を構成した。
４、 栓体の中央に所定の径の孔を形成し、該孔を通して内容液を浸出させることとして少量吐出容器を構成した。
５、 案内筒体の厚みを、下方に行くに従い徐々に薄くし、案内筒体が少なくとも摺動筒体の内面に弾性をもって接することとして少量吐出容器を構成した。 1. In a small volume discharge container in which the content liquid is stored in a bottomed cylindrical bottle and the bottle is incorporated into the cover so as to be capable of reciprocating in the axial direction.
The cover has a discharge opening at the front end, and a notch for pushing the belly of the finger around the periphery of the rear end,
With a plug inserted into the discharge port, a discharge port plug that regulates the opening area of the discharge port is assembled inside the front of the cover,
From an outer cylinder assembled to the inner peripheral surface of the cover, a partition wall that partitions the inside of the outer cylinder in the front-rear direction, an outlet formed in the partition wall, and a guide cylinder provided rearward from the periphery of the outlet The spring retainer is assembled inside the cover and behind the outlet plug,
A bottle comprising an assembly cylinder that is assembled to the inner periphery of the mouth of the bottle, and a valve body that is provided above the assembly cylinder and that is liquid-tightly and slidably inserted into the inner peripheral surface of the guide cylinder. An inner plug is assembled to the inner periphery of the mouth of the bottle,
A bottle cap comprising a cap cylinder assembled to the outer periphery of the bottle mouth and a sliding cylinder provided in the center of the top wall of the cap cylinder and slidably fitted to the outer peripheral surface of the guide cylinder Assemble to the outer periphery of the mouth of the bottle through the valve body inside the moving cylinder,
Outside the sliding cylinder, a spring is placed between the partition wall and the top wall so that the bottle and cover can be reciprocated,
When the bottle was pushed in front of the cover against the reaction force of the spring, the closing of the outlet by the valve body was released, and the small amount discharge container was configured to discharge the content liquid from the discharge port.
2. On the inner surface of the guide cylinder, a groove extending rearward from the edge of the outlet along the axial direction of the guide cylinder is formed, and when the valve body moves to the position of the groove, the outlet is closed. A small discharge container was constructed.
3. The outer peripheral surface of the plug body was formed in a predetermined shape, and a gap for leaching the content liquid was provided between the outer peripheral surface of the plug body and the inner peripheral surface of the discharge port to constitute a small-volume discharge container.
4. A small-diameter discharge container was constructed by forming a hole of a predetermined diameter in the center of the stopper and leaching the content liquid through the hole.
5. The thickness of the guide cylinder is gradually reduced as it goes downward, and the small quantity discharge container is configured such that the guide cylinder is elastically in contact with at least the inner surface of the sliding cylinder.

本発明の少量吐出容器は、次のような利点がある。   The small-volume discharge container of the present invention has the following advantages.

ボトル底部をカバーに対して軸方向に押圧することにより、流出口が開放されボトルに収納された内容液を、吐出口から浸出するように少量正確に吐出させることができる。内容液を少量吐出させる機構が全てカバー内部に設けられていることから、容器デザインの自由度を高め、良好な外観が得られる。   By pressing the bottle bottom against the cover in the axial direction, the content liquid stored in the bottle whose outlet is opened can be accurately discharged in a small amount so as to be leached from the discharge port. Since all the mechanisms for discharging a small amount of content liquid are provided inside the cover, the degree of freedom in container design is increased and a good appearance can be obtained.

ボトルとカバーとの間に設けられ、ボトルを押圧前の状態に押し戻すばねを、内容液に直接触れることのない位置に配置できる。これにより、収納された内容液にばねの影響を与える心配がなく、例えば金属製のばねを用いて、容器に高い耐久性が付与できる。   A spring that is provided between the bottle and the cover and pushes the bottle back to the state before being pressed can be arranged at a position where the content liquid is not directly touched. Thereby, there is no worry that the stored content liquid has an influence of the spring, and high durability can be imparted to the container using, for example, a metal spring.

少量吐出容器を少ない部品点数で構成できる。少量吐出容器の全体の構成を簡略化できる。簡易な組み立て工程で少量吐出容器を組み立てることができる。これらによって少量吐出容器を低い製造コストで製造できる。   A small discharge container can be configured with a small number of parts. The entire configuration of the small-volume discharge container can be simplified. A small discharge container can be assembled by a simple assembly process. By these, a small amount discharge container can be manufactured at a low manufacturing cost.

本発明にかかる少量吐出容器の一実施形態を、図面を用いて説明する。   An embodiment of a small-volume discharge container according to the present invention will be described with reference to the drawings.

少量吐出容器１を図１、図５に示す。   A small-volume discharge container 1 is shown in FIGS.

少量吐出容器１は、化粧品や薬剤などの内容液を収納したボトル２と、ボトル２を覆うカバー４と、カバー４の前方に組み付けられたオーバーキャップ６などから構成されている。   The small-volume discharge container 1 includes a bottle 2 that stores a liquid content such as cosmetics and medicine, a cover 4 that covers the bottle 2, an overcap 6 that is assembled in front of the cover 4, and the like.

口部８の内周面には、ボトル中栓１０が組み付けてある。ボトル中栓１０は、図２にも示すように組付筒体１２と、フランジ１４と、バルブ体１６から形成されている。組付筒体１２は、口部８の内周面に嵌合する筒体で、上部にフランジ１４が外方に張り出している。バルブ体１６は、有底筒体状で、上方が少し開拡したカップ状に形成してある。バルブ体１６は、支持脚１８を介してフランジ１４に固定してあり、支持脚１８の間は内容液が通過する空隙となっている。   A bottle stopper 10 is assembled on the inner peripheral surface of the mouth 8. As shown in FIG. 2, the bottle stopper 10 is formed of an assembly cylinder 12, a flange 14, and a valve body 16. The assembled cylinder 12 is a cylinder fitted to the inner peripheral surface of the mouth portion 8, and a flange 14 projects outward from the upper part. The valve body 16 has a bottomed cylindrical shape, and is formed in a cup shape whose upper part is slightly expanded. The valve body 16 is fixed to the flange 14 via the support legs 18, and a gap through which the content liquid passes is formed between the support legs 18.

口部８の外周面には、ボトルキャップ２０が組み付けてある。ボトルキャップ２０は、図２にも示すようにキャップ筒体２２と、キャップ筒体２２の上部にある頂壁２４と、頂壁２４に設けられた摺動筒体２６から形成されている。   A bottle cap 20 is assembled on the outer peripheral surface of the mouth portion 8. As shown in FIG. 2, the bottle cap 20 is formed of a cap cylinder 22, a top wall 24 at the top of the cap cylinder 22, and a sliding cylinder 26 provided on the top wall 24.

キャップ筒体２２は、内周面に雌ねじ２３を有し、雌ねじ２３により口部８の雄ねじ９に螺合する。またキャップ筒体２２の上部には、側方に突出した係合突条２５が形成してある。   The cap cylinder 22 has a female screw 23 on the inner peripheral surface, and is screwed into the male screw 9 of the mouth portion 8 by the female screw 23. Further, on the upper part of the cap cylinder 22, an engaging protrusion 25 protruding sideways is formed.

摺動筒体２６は、頂壁２４の上方に延びる円筒体で、摺動筒体２６の内部はキャップ筒体２２の内部に連通している。摺動筒体２６の外周にはばね３０が組み付けてある。ばね３０はコイルばねであり、頂壁２４と、後述するばね押さえ３８の仕切壁４０の間に組みつけられ、頂壁２４をボトル２の底部側に押圧している。   The sliding cylinder 26 is a cylindrical body extending above the top wall 24, and the inside of the sliding cylinder 26 communicates with the inside of the cap cylinder 22. A spring 30 is assembled on the outer periphery of the sliding cylinder 26. The spring 30 is a coil spring and is assembled between the top wall 24 and a partition wall 40 of a spring retainer 38 described later, and presses the top wall 24 toward the bottom side of the bottle 2.

カバー４は、図５に示すように内部にボトル２を収納できる円筒体で、前方を段階的に細くし、カバー４の前端に吐出口３２が形成してある。またカバー４の後端は開放してあり、後端の縁部には指の腹が押し入れられる切欠き３３が形成してある。   As shown in FIG. 5, the cover 4 is a cylindrical body in which the bottle 2 can be accommodated, and the front part is gradually reduced, and a discharge port 32 is formed at the front end of the cover 4. Further, the rear end of the cover 4 is open, and a notch 33 into which the belly of the finger is pushed is formed at the edge of the rear end.

カバー４の前端内面には、吐出口中栓３４が組み付けてある。吐出口中栓３４は、栓体３５と、環状の保持環３６と、支持脚３７から形成されている。栓体３５は、図３に示すように吐出口３２に内接する正六角柱状で、吐出口３２の内面に６箇所の間隙１３を設けて嵌合されている。栓体３５と保持環３６は複数の支持脚３７で連結してあり、保持環３６が、カバー４と後述するばね押さえ３８で保持されると、栓体３５が吐出口３２内に嵌合される。   On the inner surface of the front end of the cover 4, a discharge port plug 34 is assembled. The discharge port plug 34 is formed of a plug 35, an annular holding ring 36, and a support leg 37. As shown in FIG. 3, the plug 35 has a regular hexagonal column shape inscribed in the discharge port 32, and is fitted with six gaps 13 provided on the inner surface of the discharge port 32. The plug body 35 and the holding ring 36 are connected by a plurality of support legs 37. When the holding ring 36 is held by the cover 4 and a spring retainer 38 described later, the plug body 35 is fitted into the discharge port 32. The

ばね押さえ３８は、外筒３９と、仕切壁４０と、案内筒体４１とから形成されている。外筒３９は、段差を持って連結された内径の異なる上段筒体４２と下段筒体４３とからなり、下段筒体４３の下端には、内側に突出した環状の係止突状４４が形成してある。ばね押さえ３８は、カバー４の内面にカバー４の段差に合わせて固着されている。   The spring presser 38 is formed of an outer cylinder 39, a partition wall 40, and a guide cylinder 41. The outer cylinder 39 is composed of an upper cylinder 42 and a lower cylinder 43 having different inner diameters connected with a step, and an annular locking projection 44 protruding inward is formed at the lower end of the lower cylinder 43. It is. The spring retainer 38 is fixed to the inner surface of the cover 4 according to the level difference of the cover 4.

仕切壁４０は、上段筒体４３の内側に上段筒体４３を上下方向（少量吐出容器１の前後方向）に仕切るように径方向に形成してあり、中央に流出口４５が形成してある。仕切壁４０の下面には、流出口４５の周縁に沿って案内筒体４１が取り付けてある。案内筒体４１は円筒体で、案内筒体４１の内面には、ボトル２のバルブ体１６が摺動自在でかつ液密に嵌合している。また案内筒体４１の内面には、溝部４６が、流出口４５から案内筒体４１の軸方向に沿って後方に少なくとも１つ形成されている。これにより案内筒体４１の内部は、通常バルブ体１６により閉鎖されているが、バルブ体１６が溝部４６に重なる位置に移動すると、バルブ体１６の周縁と溝部４６の内部の間に間隙が生じ、案内筒体４１の内面に流路が形成される。   The partition wall 40 is formed in the radial direction so as to partition the upper cylinder 43 in the vertical direction (front-rear direction of the small amount discharge container 1) inside the upper cylinder 43, and an outlet 45 is formed in the center. . A guide cylinder 41 is attached to the lower surface of the partition wall 40 along the periphery of the outlet 45. The guide cylinder 41 is a cylinder, and the valve body 16 of the bottle 2 is slidably and liquid-tightly fitted to the inner surface of the guide cylinder 41. Further, at least one groove 46 is formed on the inner surface of the guide cylinder 41 rearward from the outlet 45 along the axial direction of the guide cylinder 41. As a result, the inside of the guide cylinder 41 is normally closed by the valve body 16, but when the valve body 16 moves to a position where it overlaps the groove 46, a gap is created between the periphery of the valve body 16 and the inside of the groove 46. A flow path is formed on the inner surface of the guide cylinder 41.

また案内筒体４１の外面は、摺動筒体２６の内面が摺動自在で、かつ液密に嵌合するように形成してある。   The outer surface of the guide cylinder 41 is formed so that the inner surface of the sliding cylinder 26 is slidable and liquid-tightly fitted.

オーバーキャップ６は、有頂円筒体で、頂板７の内面中心に突起１１が形成してある。突起１１は、吐出口３２の内周面に嵌合する形状に形成してあり、吐出口３２に嵌合すると吐出口３２を密閉する。   The overcap 6 is a cylindrical body with a top, and a protrusion 11 is formed at the center of the inner surface of the top plate 7. The protrusion 11 is formed in a shape that fits to the inner peripheral surface of the discharge port 32, and seals the discharge port 32 when fitted to the discharge port 32.

次に少量吐出容器１の使用方法などについて説明する。   Next, how to use the small-volume discharge container 1 will be described.

ボトル２は、樹脂成形した後、内部に化粧品や薬剤などの内容液を収納し、ボトル中栓１０を口部８の内周面に組み付け、その上でボトルキャップ２０をねじ９に螺合して組み付ける。尚、ボトルキャップ２０をねじ９を用いず、アンダーカットなどによりボトル２に組み付けてもよい。そのような場合、ボトル中栓１０やボトルキャップ２０をボトル２に直接組み付けるのでなく、カバー４の側に予め組み付けておき、その後ボトル２をボトルキャップ２０など取り付けるようにしてもよい。   After the bottle 2 is resin-molded, it contains a liquid content such as cosmetics and medicines, the bottle stopper 10 is assembled to the inner peripheral surface of the mouth 8, and the bottle cap 20 is screwed onto the screw 9. Assemble. The bottle cap 20 may be assembled to the bottle 2 by undercut or the like without using the screw 9. In such a case, the bottle stopper 10 and the bottle cap 20 may not be directly assembled to the bottle 2 but may be assembled in advance on the cover 4 side, and then the bottle 2 may be attached.

カバー４は、樹脂成形した後、底部より吐出口中栓３４を差し入れ、栓体３５を吐出口３２の内側に組み付ける。その後ばね押さえ３８を吐出口中栓３４と同様に、カバー４の底部より内部に差し入れ、前端内面に固着させる。   After the cover 4 is resin-molded, the outlet plug 34 is inserted from the bottom, and the plug 35 is assembled inside the outlet 32. Thereafter, the spring retainer 38 is inserted into the inside from the bottom of the cover 4 in the same manner as the outlet plug 34 and fixed to the inner surface of the front end.

ボトルキャップ２０の摺動筒体２６の外周にばね３０を組み付け、上記ボトル２をカバー４の底部よりカバー４内に差し入れる。するとキャップ筒体２２の外方に設けられた係合突状２５がばね押さえ３８の係止突状４４を越えて、キャップ筒体２２がばね押さえ３８の下段筒体４３内に挿入される。これにより、ボトル２はカバー４から抜け出ることが防止される。   A spring 30 is assembled to the outer periphery of the sliding cylinder 26 of the bottle cap 20, and the bottle 2 is inserted into the cover 4 from the bottom of the cover 4. Then, the engagement protrusion 25 provided outside the cap cylinder 22 exceeds the locking protrusion 44 of the spring retainer 38, and the cap cylinder 22 is inserted into the lower cylinder 43 of the spring retainer 38. Thereby, the bottle 2 is prevented from coming out of the cover 4.

また摺動筒体２６が案内筒体４１の外周面に嵌合し、更にバルブ体１６が案内筒体４１の内周面に液密に嵌合し、案内筒体４１の内部を閉鎖する。オーバーキャップ６をカバー４に取り付けると、オーバーキャップ６に設けられている突起１１が吐出口３２に組み付き、吐出口３２を密閉する。かかる状態を図１に示す。   Further, the sliding cylinder 26 is fitted to the outer peripheral surface of the guide cylinder 41, and the valve body 16 is liquid-tightly fitted to the inner peripheral surface of the guide cylinder 41 to close the inside of the guide cylinder 41. When the overcap 6 is attached to the cover 4, the protrusion 11 provided on the overcap 6 is assembled to the discharge port 32, and the discharge port 32 is sealed. Such a state is shown in FIG.

内容液を吐出させるには、オーバーキャップ６をカバー４の前端から取り外し、吐出口３２を開放させる。そしてカバー４を握り、吐出口３２を下方に向けて親指の腹でボトル２の底部を押圧する。   In order to discharge the content liquid, the overcap 6 is removed from the front end of the cover 4 and the discharge port 32 is opened. Then, the cover 4 is gripped, and the bottom of the bottle 2 is pressed with the belly of the thumb with the discharge port 32 facing downward.

すると、ばね３０が押し縮められてボトル２がカバー４の内部に押し込まれる。図２にボトル２をカバー４内に押し込んだ状態を示す。ボトル２をカバー４内に押し込むと、案内筒体４１内でバルブ体１６が移動して溝部４６の位置に重なり、案内筒体４１に流路が形成される。   Then, the spring 30 is compressed and the bottle 2 is pushed into the cover 4. FIG. 2 shows a state in which the bottle 2 is pushed into the cover 4. When the bottle 2 is pushed into the cover 4, the valve body 16 moves in the guide cylinder 41 and overlaps the position of the groove 46, and a flow path is formed in the guide cylinder 41.

すると内容液が流出口４５から流出し、流出した内容液が吐出口中栓３４の支持脚３７の間を通過し、栓体３５と吐出口３２の間隙１３から浸出するようにカバー４の外に吐出される。   Then, the content liquid flows out from the outflow port 45, and the outflowed content liquid passes between the support legs 37 of the discharge port inner plug 34 and is squeezed out of the gap 4 between the plug body 35 and the discharge port 32. Discharged.

親指をボトル２の底部から離すと、ばね３０の反力でボトル２は元の位置に戻され、バルブ体１６が案内筒体４１を閉鎖する。   When the thumb is released from the bottom of the bottle 2, the bottle 2 is returned to the original position by the reaction force of the spring 30, and the valve body 16 closes the guide cylinder 41.

このように少量吐出容器１によれば、ボトル２の底部を押圧することにより、バルブ体１６が案内筒体４１内で移動して流路を案内筒体４１内に形成し、それにより内容液を流出させるので、少量の内容液を正確に、かつ確実に吐出させることができる。   As described above, according to the small-volume discharge container 1, by pressing the bottom of the bottle 2, the valve body 16 moves in the guide cylinder 41 to form a flow path in the guide cylinder 41, whereby the content liquid As a result, a small amount of the content liquid can be discharged accurately and reliably.

また案内筒体４１と摺動筒体２６が液密に接していることから、内容液が漏出することがない。更にばね３０が摺動筒体２６の外方に配置してあることから、ばね３０を自由に構成でき、しかもばね３０をどのように構成しても内容液になんら影響を及ぼすことがない。   Further, since the guide cylinder 41 and the sliding cylinder 26 are in liquid-tight contact, the content liquid does not leak out. Further, since the spring 30 is disposed outside the sliding cylinder 26, the spring 30 can be freely configured, and no matter what the spring 30 is configured, the content liquid is not affected.

図４に少量吐出容器の他の例を示す。   FIG. 4 shows another example of a small amount discharge container.

この少量吐出容器３は、吐出口中栓３４を次のように形成した。すなわち保持環３６と栓体３５とを円筒体で連結し、かつ栓体３５の中心に、栓体３５を上下方向に貫通する孔１５を設けて形成した。また案内筒体４１の厚みを、案内筒体４１の下方に行くに従い順次薄くなるように形成した。案内筒体４１の内面には溝部を形成せず、ボトル２の底部を押圧するとバルブ体１６が流出口４５から二点鎖線で示すように抜け出て、流出口４５を開放させる構成とした。更に摺動筒体２６の上部内側の周縁に丸みを設けた。   In the small-volume discharge container 3, a discharge port plug 34 was formed as follows. That is, the holding ring 36 and the plug body 35 are connected by a cylindrical body, and a hole 15 penetrating the plug body 35 in the vertical direction is provided at the center of the plug body 35. In addition, the thickness of the guide cylinder 41 is formed so as to decrease gradually as it goes below the guide cylinder 41. A groove portion is not formed on the inner surface of the guide cylinder 41, and when the bottom of the bottle 2 is pressed, the valve body 16 comes out from the outlet 45 as shown by a two-dot chain line, and the outlet 45 is opened. Furthermore, the roundness was provided in the periphery inside the upper part of the sliding cylinder 26. FIG.

尚少量吐出容器３の他の部材は、上記少量吐出容器１の部材と構成が同様であるので、同一の符号を付して説明を省略する。   Since the other members of the small-volume discharge container 3 have the same configuration as the members of the small-volume discharge container 1, the same reference numerals are given and description thereof is omitted.

これにより少量吐出容器３は、ボトル２の底部を押圧するとバルブ体１６が流出口４５を開放させ、内容液を吐出口３２より少量ずつ吐出する。吐出口３２の開口面積は孔１５の直径によって任意に設定でき、吐出口３２を通過する内容液の流通抵抗を栓体３５の縦方向の長さと孔１５の直径により自由に設定し、内容液の吐出流量を任意にできる。   Thus, when the small amount discharge container 3 presses the bottom of the bottle 2, the valve body 16 opens the outlet 45 and discharges the content liquid from the discharge port 32 little by little. The opening area of the discharge port 32 can be arbitrarily set according to the diameter of the hole 15, and the flow resistance of the content liquid passing through the discharge port 32 can be freely set by the longitudinal length of the plug body 35 and the diameter of the hole 15. The discharge flow rate can be arbitrarily set.

また案内筒体４１の厚みを、下方に行くに従い徐々に薄くしたので、案内筒体４１の内周面とバルブ体１６の外周面、及び案内筒体４１の外周面と摺動筒体２６の内周面とをそれぞれ弾性をもって互いに接触させることができ、密着の度合いを高め、かつ密着した状態を長時間保持できる。また摺動筒体２６の上部内側の周縁に丸みを設けたので案内筒体４１を摺動筒体２６に挿入し易くなり、バルブ体１６が案内筒体４１の内側に挿入されて案内筒体４１の下方が外方に拡がったとしても、案内筒体４１を摺動筒体２６の内側に容易に嵌合できる。   Further, since the thickness of the guide cylinder 41 is gradually reduced as it goes downward, the inner peripheral surface of the guide cylinder 41 and the outer peripheral surface of the valve body 16, and the outer peripheral surface of the guide cylinder 41 and the sliding cylinder 26 The inner peripheral surfaces can be brought into contact with each other with elasticity, the degree of close contact can be increased, and the close contact state can be maintained for a long time. Further, since the upper inner periphery of the sliding cylinder 26 is rounded, the guide cylinder 41 can be easily inserted into the sliding cylinder 26, and the valve body 16 is inserted inside the guide cylinder 41 to guide the cylinder. Even if the lower part of 41 expands outward, the guide cylinder 41 can be easily fitted inside the sliding cylinder 26.
