Description

本発明は、塗布容器に関する。   The present invention relates to a coating container.

従来から、人体の頭皮等の被塗布部に対して薬液等の内容物を塗布する塗布容器が知られている。この種の塗布容器は、内容物が収容される有底筒状の容器本体と、容器本体の口部に装着され、容器本体内に連通する連通孔を有する中栓部材と、中栓部材との間に、連通孔を通して容器本体内に連通する計量室を形成する計量筒部材と、計量筒部材から外部に突出するとともに、計量室内に連通する吐出孔を有する弁部材と、を備えている(例えば、下記特許文献1参照)。   2. Description of the Related Art Conventionally, an application container for applying contents such as a chemical solution to an application part such as a human scalp is known. This type of application container includes a bottomed cylindrical container main body in which contents are stored, an inner plug member that is attached to the mouth of the container main body and has a communication hole that communicates with the container main body, and an inner plug member. A measuring cylinder member forming a measuring chamber communicating with the inside of the container body through the communication hole, and a valve member protruding outside from the measuring cylinder member and having a discharge hole communicating with the measuring chamber. (For example, refer to Patent Document 1 below).

また、上述した弁部材は、弁部材の吐出孔を通した外部と計量室内との連通を遮断し、かつ計量室内と容器本体内とを連通させる計量位置と、容器軸方向における計量位置よりも容器本体の底部側に位置するとともに、計量室内と容器本体内との連通を遮断し、かつ計量室内と外部とを連通させる塗布位置と、の間を容器軸方向に移動自在に配設されている。   In addition, the valve member described above has a weighing position that blocks communication between the outside through the discharge hole of the valve member and the measurement chamber and allows the measurement chamber to communicate with the inside of the container body, and a measurement position in the container axial direction. It is located on the bottom side of the container body, and is disposed so as to be movable in the container axial direction between the application position that blocks the communication between the measurement chamber and the container body and allows the measurement chamber to communicate with the outside. Yes.

上述した塗布容器において、内容物を被塗布部に塗布するには、まず弁部材を計量位置に移動させた状態で塗布容器を倒立姿勢にし、容器本体内の内容物を計量室内に流入させる。これにより、計量室に所定量の内容物が計量される。この状態で、弁部材の先端部を被塗布部に押し付ける。すると、弁部材が塗布位置に移動することで、計量室内の内容物が弁部材の吐出孔を通して吐出される。これにより、被塗布部に内容物が塗布される。   In the above-described application container, in order to apply the contents to the application portion, first, the application container is turned upside down with the valve member moved to the measurement position, and the contents in the container body are allowed to flow into the measurement chamber. As a result, a predetermined amount of content is weighed in the weighing chamber. In this state, the tip of the valve member is pressed against the application portion. Then, when the valve member moves to the application position, the contents in the measurement chamber are discharged through the discharge hole of the valve member. As a result, the contents are applied to the application portion.

しかしながら、上述した従来の塗布容器では、塗布位置において、弁部材の吐出孔を通して吐出される内容物の吐出量を制御することが難しく、吐出精度を高めることに改善の余地があった。   However, in the above-described conventional application container, it is difficult to control the discharge amount of the contents discharged through the discharge hole of the valve member at the application position, and there is room for improvement in improving the discharge accuracy.

そこで、本発明は、上述した事情に鑑みてなされたものであって、その目的は、吐出精度の向上を図ることができる塗布容器を提供することである。   Therefore, the present invention has been made in view of the above-described circumstances, and an object thereof is to provide a coating container capable of improving the discharge accuracy.

前記課題を解決するために、本発明は以下の手段を提案している。
本発明に係る塗布容器は、被塗布部に塗布する内容物が収容される容器本体と、前記容器本体の口部に装着され、前記容器本体内に連通する連通孔を有する中栓部材と、前記中栓部材との間に、前記連通孔を通して前記容器本体内に連通する計量室を形成するとともに、前記計量室内に連通する吐出孔が頂部に形成された計量筒部材と、前記計量室内に設けられ、先端部が前記吐出孔から外部に突出可能な塗布栓と、を備え、前記塗布栓は、前記計量室内と外部との連通を遮断し、かつ前記計量室内と前記容器本体内とを連通させる計量位置と、容器軸方向において前記計量位置よりも前記容器本体の底部側に位置するとともに、前記計量室内と前記容器本体内との連通を遮断し、かつ前記計量室内と外部とを連通させる塗布位置と、の間を容器軸方向に移動自在に配設され、前記計量筒部材の頂部は、前記塗布栓が前記塗布位置にある状態において、容器軸方向に沿う前記容器本体の底部側に向けて弾性変形可能に形成されていることを特徴とする。
In order to solve the above problems, the present invention proposes the following means.
An application container according to the present invention is a container main body in which contents to be applied to an application portion are accommodated, an inner plug member that is attached to a mouth portion of the container main body and has a communication hole communicating with the inside of the container main body, A measuring chamber communicating with the inside of the container body through the communication hole is formed between the inner plug member and a measuring cylinder member having a discharge hole communicating with the measuring chamber formed at the top thereof, and the measuring chamber. And a coating plug that can protrude outward from the discharge hole, and the coating plug blocks communication between the measurement chamber and the outside, and connects the measurement chamber and the container body. The measuring position to be communicated with and positioned at the bottom side of the container main body with respect to the container axial direction in the container axial direction, the communication between the measuring chamber and the inside of the container main body is cut off, and the measuring chamber is communicated with the outside. Between the application position Disposed movably in the vessel axis, the top of the metering cylinder member, in a state where the coating plug is in the application position, elastically deformable formed toward the bottom side of the container body along the axial direction of the container It is characterized by being.

このような特徴により、塗布栓が計量位置にある状態で、塗布容器を塗布栓が下向きの例えば倒立姿勢等にすると、容器本体内の内容物が、連通孔を通して計量室内に流入する一方、この内容物の外部への流出は防止されている。そのため、計量室内に所定量の内容物が計量される。
その後、前記倒立姿勢等のままで塗布栓を塗布位置に移動させることで、計量室内の内容物を吐出孔を通して被塗布部に吐出することができる。
ここで、塗布栓が塗布位置にある状態において、計量筒部材の頂部を被塗布部に押し当てると、その押付力に応じて頂部が容器軸方向に弾性変形する。すると、計量室内が加圧されることで、計量室内から吐出孔に向けて流通する内容物の流量が増大する。これにより、吐出孔から吐出される内容物の流量を増大させることができる。このように、計量筒部材の頂部の押付力、つまり頂部の変形量を調整することで、吐出孔から吐出される内容物の流量を制御することができる。その結果、吐出精度の向上を図ることができる。
また、容器軸方向に弾性変位可能な計量筒部材の頂部を被塗布部に押し付けるので、塗布時において、被塗布部に及ぼされる衝撃や外力等が頂部のクッション作用により緩和されることになる。そのため、柔らかな塗布感触を得ることができるとともに、不快さや心地悪さを低減し、快適で心地よい塗布を行うことができる。
Due to such a feature, when the coating container is in the metering position and the coating container is turned downward, for example, in an inverted position, the contents in the container body flow into the measurement chamber through the communication hole. Outflow of contents to the outside is prevented. Therefore, a predetermined amount of contents are weighed in the weighing chamber.
Thereafter, by moving the application plug to the application position while maintaining the inverted posture or the like, the contents in the measurement chamber can be discharged to the application portion through the discharge holes.
Here, when the top portion of the measuring cylinder member is pressed against the application portion in a state where the application plug is at the application position, the top portion is elastically deformed in the container axial direction according to the pressing force. Then, by pressurizing the measurement chamber, the flow rate of contents flowing from the measurement chamber toward the discharge hole increases. Thereby, the flow volume of the content discharged from a discharge hole can be increased. Thus, the flow rate of the content discharged from the discharge hole can be controlled by adjusting the pressing force of the top of the measuring cylinder member, that is, the amount of deformation of the top. As a result, the discharge accuracy can be improved.
In addition, since the top of the measuring cylinder member that can be elastically displaced in the container axial direction is pressed against the portion to be coated, the impact, external force, etc. exerted on the portion to be coated are alleviated by the cushioning action of the top. Therefore, it is possible to obtain a soft application feeling, reduce uncomfortableness and uncomfortableness, and perform a comfortable and comfortable application.

前記計量筒部材の頂部は、前記計量筒部材の周壁部に連設され容器軸方向に弾性変形可能な変形壁部と、前記変形壁部に立設され内部に前記吐出孔が設けられた吐出筒と、を備えていてもよい。   The top part of the measuring cylinder member is connected to the peripheral wall part of the measuring cylinder member and can be elastically deformed in the container axial direction. The discharge wall is provided on the deformation wall part and provided with the discharge hole inside. And a tube.

この場合、塗布栓の先端部が、吐出筒内に容器軸方向に摺動自在に嵌合されているので、計量筒部材の頂部が容器軸方向に弾性変形するときに、頂部のうち、吐出筒を被塗布部に押し当てて、被塗布部からの反力を吐出筒を介して変形壁部に確実に伝達させることできる。これにより、変形壁部を安定して変形させることが可能になり、吐出精度の更なる向上を図ることができる。   In this case, since the tip of the coating plug is slidably fitted in the discharge tube in the container axial direction, when the top of the measuring tube member is elastically deformed in the container axial direction, The tube can be pressed against the portion to be coated, and the reaction force from the portion to be coated can be reliably transmitted to the deformation wall portion via the discharge tube. Thereby, it becomes possible to deform | transform a deformation | transformation wall part stably, and can aim at the further improvement of discharge accuracy.

前記塗布栓の先端部は、前記吐出筒内に容器軸方向に摺動自在に嵌合され、前記塗布栓の外周面には、前記塗布栓が前記塗布位置に位置するときに前記計量室内を外部に連通させる連通凹部が設けられていてもよい。   The distal end of the application plug is slidably fitted in the discharge cylinder in the container axial direction, and the outer surface of the application plug is located inside the measurement chamber when the application plug is located at the application position. A communication recess that communicates with the outside may be provided.

この場合、塗布栓の先端部は、吐出筒内に容器軸方向に摺動自在に嵌合されているので、吐出筒を塗布栓の先端部に対して容器軸方向に摺動させ、頂部を容器軸方向に安定して弾性変形させることができる。
さらに塗布栓の外周面に、連通凹部が設けられているので、計量筒部材の頂部が容器軸方向に弾性変形して吐出筒が塗布栓の先端部に対して容器軸方向に摺動したとしても、計量室内を外部に安定して連通させることが可能になり、吐出精度の確実な向上を図ることができる。
In this case, since the tip of the coating stopper is slidably fitted in the container axial direction in the discharge cylinder, the discharge cylinder is slid in the container axial direction with respect to the tip of the coating stopper, and the top is It can be elastically deformed stably in the container axial direction.
Further, since the communication recess is provided on the outer peripheral surface of the coating plug, the top of the measuring cylinder member is elastically deformed in the container axial direction, and the discharge cylinder slides in the container axial direction with respect to the tip of the coating plug. However, it is possible to stably communicate the measurement chamber with the outside, and the discharge accuracy can be reliably improved.

前記吐出筒の先端部には、容器軸方向に突出する突出部が、前記吐出筒の周方向に間隔をあけて複数配置されていてもよい。   A plurality of protrusions protruding in the container axial direction may be disposed at the distal end of the discharge cylinder at intervals in the circumferential direction of the discharge cylinder.

この場合、吐出筒の先端部に、突出部が周方向に間隔をあけて複数配置されているので、内容物の吐出時に、内容物を、周方向に隣り合う突出部同士の間を通して被塗布部に塗布しつつ、計量筒部材の頂部の容器軸方向への弾性変形をより安定させることができる。   In this case, since a plurality of protrusions are arranged at intervals in the circumferential direction at the tip of the discharge cylinder, the contents are applied through the gap between the protrusions adjacent in the circumferential direction when discharging the contents. The elastic deformation in the container axial direction of the top of the measuring cylinder member can be further stabilized while being applied to the portion.

本発明によれば、吐出精度の向上を図ることができる。   According to the present invention, it is possible to improve the discharge accuracy.

次に、上述した塗布容器10の作用について説明する。なお以下の説明では、図1および図2に示すような、オーバーキャップ16が容器本体11の口部11aに装着された状態を初期状態とする。初期状態の塗布容器10では、塗布栓14が、計量室29内と容器本体11内との連通孔21を通した連通を遮断し、かつ吐出孔35を通して計量室29内と外部とを連通させる塗布位置P2に位置している。塗布位置P2において、塗布栓14の先端面は、計量筒部材13の頂部34の先端面(突出部40の先端面)よりも下方に位置している。   Next, the effect | action of the application | coating container 10 mentioned above is demonstrated. In the following description, a state in which the overcap 16 is attached to the mouth portion 11a of the container body 11 as shown in FIGS. 1 and 2 is an initial state. In the coating container 10 in the initial state, the coating plug 14 blocks communication between the inside of the measuring chamber 29 and the inside of the container body 11 through the communication hole 21 and allows the inside of the measuring chamber 29 to communicate with the outside through the discharge hole 35. It is located at the application position P2. At the application position P <b> 2, the distal end surface of the application plug 14 is located below the distal end surface of the top portion 34 of the measuring cylinder member 13 (the distal end surface of the protruding portion 40).

初期状態の塗布容器10において、容器本体11の口部11aとオーバーキャップ16との螺着を解除し、オーバーキャップ16を取り外す。オーバーキャップ16と容器本体11とを螺着が解除される方向に相対回転させると、この相対回転に伴いオーバーキャップ16が容器本体11に対して上方移動する。このときオーバーキャップ16が、係止筒63、第2係止部63aおよび第1係止部43aを介して塗布栓14に係止されているため、オーバーキャップ16の上方移動に伴い、塗布栓14が引き上げられる。   In the coating container 10 in the initial state, the screwing between the mouth 11a of the container body 11 and the overcap 16 is released, and the overcap 16 is removed. When the overcap 16 and the container body 11 are relatively rotated in the direction in which the screwing is released, the overcap 16 moves upward with respect to the container body 11 along with the relative rotation. At this time, since the overcap 16 is locked to the coating plug 14 via the locking cylinder 63, the second locking portion 63a, and the first locking portion 43a, the coating cap is moved along with the upward movement of the overcap 16. 14 is raised.

またこのとき塗布栓14は、図4および図5に示すように、連結段部44が計量筒部材13の頂壁に当接して更なる上方移動が規制されるまで、オーバーキャップ16とともに引き上げられる。この状態で、オーバーキャップ16と容器本体11とを螺着が解除される方向にさらに相対回転させると、塗布栓14に対してオーバーキャップ16が上方移動することで、第1係止部43aと第2係止部63aとが互いに乗り越える。これにより、オーバーキャップ16と塗布栓14との係止が解除され、オーバーキャップ16のみが上方移動することで、オーバーキャップ16と容器本体11の螺着が解除され、オーバーキャップ16が取り外される。   At this time, as shown in FIGS. 4 and 5, the application plug 14 is pulled up together with the overcap 16 until the connecting step 44 contacts the top wall of the measuring cylinder member 13 and further upward movement is restricted. . In this state, when the overcap 16 and the container main body 11 are further rotated relative to each other in the direction in which the screwing is released, the overcap 16 moves upward with respect to the application plug 14, thereby the first locking portion 43 a The second locking portion 63a gets over each other. As a result, the locking of the overcap 16 and the coating plug 14 is released, and only the overcap 16 moves upward, so that the screwing of the overcap 16 and the container body 11 is released, and the overcap 16 is removed.

このとき塗布栓14のシール部45は、中栓部材12の外筒25から離脱されていて、中栓部材12の連通孔21と計量室29内とは、シール部45の下端と外筒25の上端との間を通して連通されている。一方、塗布栓14の小径部43において連通凹部41よりも下側に位置する部分が、吐出孔35内に液密に嵌合されており、連通凹部41と計量室29との連通が遮断され、これにより計量室29と吐出孔35との連通が遮断されている。このように塗布栓14は、オーバーキャップ16を取り外した直後には、吐出孔35を通した計量室29内と外部との連通を遮断し、かつ計量室29内と容器本体11内とを連通孔21を通して連通させる計量位置P1に位置する。   At this time, the seal portion 45 of the coating plug 14 is detached from the outer cylinder 25 of the inner plug member 12, and the communication hole 21 of the inner plug member 12 and the inside of the measuring chamber 29 are the lower end of the seal portion 45 and the outer cylinder 25. Is communicated with the upper end of the. On the other hand, the portion of the small diameter portion 43 of the coating plug 14 located below the communication recess 41 is liquid-tightly fitted in the discharge hole 35, and the communication between the communication recess 41 and the measuring chamber 29 is blocked. Thereby, the communication between the measuring chamber 29 and the discharge hole 35 is blocked. Thus, immediately after the overcap 16 is removed, the application plug 14 blocks communication between the inside of the measuring chamber 29 through the discharge hole 35 and the outside, and also connects the inside of the measuring chamber 29 and the inside of the container body 11. It is located at a metering position P1 communicating with the hole 21.

次に、容器本体11内の内容物を計量室29内に流入させる。塗布栓14が計量位置P1にある状態で、塗布容器10を塗布栓14が下向きとなる倒立姿勢とする。すると、容器本体11内の内容物が、連通孔21を通して計量室29内に流入する。一方、計量位置P1においては、塗布栓14の連通凹部41と計量室29内との連通が遮断されているため、連通凹部41を通した外部への内容物の流出が防止されている。これにより、計量室29内に所定量の内容物が計量される。なお、倒立姿勢では、塗布容器10の上下が反転するため、容器軸O方向に沿う塗布栓14側が下側、容器本体11側が上側となる。   Next, the contents in the container main body 11 are caused to flow into the measuring chamber 29. In a state where the application plug 14 is in the measuring position P1, the application container 10 is set in an inverted posture in which the application plug 14 faces downward. Then, the contents in the container main body 11 flow into the measuring chamber 29 through the communication hole 21. On the other hand, at the measuring position P1, the communication between the communication concave portion 41 of the coating plug 14 and the inside of the measurement chamber 29 is blocked, so that the outflow of contents to the outside through the communication concave portion 41 is prevented. As a result, a predetermined amount of contents are weighed in the weighing chamber 29. In the inverted posture, the upper and lower sides of the application container 10 are inverted, so that the application stopper 14 side along the container axis O direction is the lower side and the container body 11 side is the upper side.

続いて、図6に示すように、塗布容器10を倒立姿勢に維持した状態で、塗布栓14を被塗布部Sに押し付けると、塗布栓14が計量筒部材13に対して上方に向けて移動する。このときまず、塗布栓14のシール部45が中栓部材12の外筒25内に嵌合される前に、塗布栓14の連通凹部41と計量室29内との連通の遮断が解除される中間位置P3に移動する。その後、図7に示すように、塗布栓14のシール部45が受け部24の外筒25内に嵌合される塗布位置P2まで塗布栓14を移動させる。なお、シール部45が外筒25内に嵌合された後に、連通凹部41と計量室29内とが連通されてもよい。
塗布栓14が塗布位置P2に移動すると、計量室29内の内容物が連通凹部41を通して吐出孔35内に流入して被塗布部S上(外部)に吐出される。
Subsequently, as shown in FIG. 6, when the application plug 14 is pressed against the application portion S while the application container 10 is maintained in the inverted posture, the application plug 14 moves upward with respect to the measuring cylinder member 13. To do. At this time, first, before the seal portion 45 of the application plug 14 is fitted into the outer cylinder 25 of the inner plug member 12, the disconnection of the communication between the communication recess 41 of the application plug 14 and the inside of the measuring chamber 29 is released. Move to the intermediate position P3. Thereafter, as shown in FIG. 7, the application plug 14 is moved to the application position P <b> 2 where the seal portion 45 of the application plug 14 is fitted in the outer cylinder 25 of the receiving portion 24. Note that the communication recess 41 and the inside of the measurement chamber 29 may be communicated after the seal portion 45 is fitted in the outer cylinder 25.
When the application plug 14 moves to the application position P2, the contents in the measuring chamber 29 flow into the discharge hole 35 through the communication recess 41 and are discharged onto the application portion S (outside).

ここで、塗布栓14が塗布位置P2にある状態において、計量筒部材13の頂部34を被塗布部Sに押し当てると、図8に示すように、その押付力に応じて頂部34が容器軸O方向に弾性変形する。このとき、頂部34の吐出筒37が塗布栓14に対して容器軸O方向に摺動する一方、変形壁部36が、環状部39の内周縁部を上方移動させて変形する。すると、計量室29が加圧されることで、計量室29内から吐出孔35に向けて流通する内容物の流量が増大する。また図9に示すように、計量筒部材13の頂部34の被塗布部Sへの押し付けを弱めたり解除したりすると、計量筒部材13は容器軸O方向に復元変形して計量室29が減圧され、内容物の流量が減少する。これにより、被塗布部Sに吐出される内容物の吐出量を調整することができる。なお図8に示すように、本実施形態では、計量筒部材13の頂部34の上方への弾性変形に伴って、塗布栓14も更に上方移動する。塗布栓14の上方移動は、塗布栓14の連結段部44が受け部24の内筒26に下方から当接することで規制される。   Here, when the top part 34 of the measuring cylinder member 13 is pressed against the application part S in the state where the application plug 14 is at the application position P2, as shown in FIG. Elastically deforms in the O direction. At this time, the discharge cylinder 37 of the top 34 slides in the container axis O direction with respect to the coating stopper 14, while the deformation wall 36 is deformed by moving the inner peripheral edge of the annular portion 39 upward. Then, the measurement chamber 29 is pressurized, so that the flow rate of contents flowing from the measurement chamber 29 toward the discharge hole 35 increases. As shown in FIG. 9, when the pressing of the top 34 of the measuring cylinder member 13 to the application portion S is weakened or released, the measuring cylinder member 13 is restored and deformed in the container axis O direction, and the measuring chamber 29 is decompressed. And the flow rate of the contents is reduced. Thereby, the discharge amount of the content discharged to the to-be-coated part S can be adjusted. As shown in FIG. 8, in the present embodiment, the coating plug 14 further moves upward along with the elastic deformation of the top 34 of the measuring cylinder member 13 upward. The upward movement of the coating plug 14 is restricted by the connection step portion 44 of the coating plug 14 coming into contact with the inner cylinder 26 of the receiving portion 24 from below.

ところで前記塗布容器10では、図10(a)、(b)それぞれにおける容器軸O方向の大きさA、B、Cが、A+B<Cの関係を満たすように調整されている。
図10(a)に示すAは、オーバーキャップ16を取り外した直後に塗布栓14が計量位置P1に位置する状態(以下、「基準状態」という)における、連通凹部41の計量室29側の端部と、吐出孔35の内周面に設けられたシール突起35aと、の容器軸O方向の距離である。連通凹部41の計量室29側の端部が、シール突起35aを容器軸O方向に通過すると、計量室29内が連通凹部41を通して外部に連通する。
図10(a)に示すCは、基準状態における、シール部45の外筒25側の端部と、外筒25の内周面に設けられた被シール部25aと、の容器軸O方向の距離である。シール部45の外筒25側の端部が、被シール部25aを容器軸O方向に通過すると、シール部45が外筒25内に液密に嵌合される。
図10(b)に示すBは、頂部34の容器軸O方向への弾性変形の限界量である。
これらの容器軸O方向の大きさA、B、Cについて、上述したようにA+B<Cの関係を満たすように調整することで、基準状態において、仮に頂部34が限界量Bまで容器軸O方向に弾性変形したとしても、シール部45が外筒25内に液密に嵌合される前に、計量室29内が連通凹部41を通して外部に連通する。
By the way, in the said application | coating container 10, size A, B, C of the container axis | shaft O direction in each of FIG. 10 (a), (b) is adjusted so that the relationship of A + B <C may be satisfy | filled.
A shown in FIG. 10A is an end on the measuring chamber 29 side of the communication recess 41 in a state where the coating plug 14 is positioned at the measuring position P1 immediately after the overcap 16 is removed (hereinafter referred to as “reference state”). This is the distance in the container axis O direction between the portion and the seal protrusion 35 a provided on the inner peripheral surface of the discharge hole 35. When the end of the communication recess 41 on the weighing chamber 29 side passes through the seal projection 35a in the container axis O direction, the inside of the measurement chamber 29 communicates with the outside through the communication recess 41.
C shown in FIG. 10A is the container axis O direction between the end portion of the seal portion 45 on the outer cylinder 25 side and the sealed portion 25a provided on the inner peripheral surface of the outer cylinder 25 in the reference state. Distance. When the end portion on the outer cylinder 25 side of the seal portion 45 passes through the sealed portion 25a in the container axis O direction, the seal portion 45 is fitted in the outer tube 25 in a liquid-tight manner.
B shown in FIG. 10B is a limit amount of elastic deformation of the top 34 in the container axis O direction.
By adjusting these sizes A, B, and C in the container axis O direction so as to satisfy the relationship of A + B <C as described above, in the reference state, the top 34 temporarily reaches the limit amount B in the container axis O direction. Even if elastically deformed, the inside of the measurement chamber 29 communicates with the outside through the communication recess 41 before the seal portion 45 is liquid-tightly fitted into the outer cylinder 25.

以上説明したように、本実施形態に係る塗布容器10によれば、計量筒部材13の頂部34が、容器軸O方向に弾性変形可能に形成されているので、計量筒部材13の頂部34の押付力、つまり頂部34の変形量を調整することで、吐出孔35から吐出される内容物の流量を制御することができる。その結果、吐出精度の向上を図ることができる。
なお本実施形態では、頂部34が弾性変形していない状態や復元変形している状態では、計量室29の内圧が低く、内容物の予期せぬ流出が阻害されている一方、頂部34が弾性変形すると、計量室29の内圧が高まり内容物が吐出し易くなる。したがって、頂部34の弾性変位および復元変位を繰り返すことで、内容物を複数回に分けて小出しにすることができる。
As described above, according to the application container 10 according to the present embodiment, the top portion 34 of the measuring cylinder member 13 is formed to be elastically deformable in the container axis O direction. By adjusting the pressing force, that is, the amount of deformation of the top 34, the flow rate of the contents discharged from the discharge hole 35 can be controlled. As a result, the discharge accuracy can be improved.
In the present embodiment, when the top portion 34 is not elastically deformed or restored, the internal pressure of the measuring chamber 29 is low, and the unexpected outflow of contents is inhibited, while the top portion 34 is elastic. When it is deformed, the internal pressure of the measuring chamber 29 is increased and the contents are easily discharged. Therefore, by repeating the elastic displacement and the restoring displacement of the top portion 34, the contents can be divided into a plurality of times and dispensed.

また、容器軸O方向に弾性変位可能な計量筒部材13の頂部34を被塗布部Sに押し付けるので、塗布時において、被塗布部Sに及ぼされる衝撃や外力等が頂部34のクッション作用により緩和されることになる。そのため、柔らかな塗布感触を得ることができるとともに、不快さや心地悪さを低減し、快適で心地よい塗布を行うことができる。   In addition, since the top 34 of the measuring cylinder member 13 that can be elastically displaced in the container axis O direction is pressed against the portion S to be coated, the impact, external force, etc. exerted on the portion S to be coated are reduced by the cushioning action of the top 34 during coating. Will be. Therefore, it is possible to obtain a soft application feeling, reduce uncomfortableness and uncomfortableness, and perform a comfortable and comfortable application.

また塗布栓14の先端部が、吐出筒37内に容器軸O方向に摺動自在に嵌合されているので、計量筒部材13の頂部34が容器軸O方向に弾性変形するときに、頂部34のうち、吐出筒37を被塗布部Sに押し当てて、被塗布部Sからの反力を吐出筒37を介して変形壁部36に確実に伝達させることできる。これにより、変形壁部36を安定して変形させることが可能になり、吐出精度の更なる向上を図ることができる。   Further, since the distal end portion of the coating plug 14 is slidably fitted in the discharge tube 37 in the direction of the container axis O, the top portion of the measuring tube member 13 is elastically deformed in the direction of the container axis O. 34, the discharge cylinder 37 can be pressed against the application part S, and the reaction force from the application part S can be reliably transmitted to the deformed wall part 36 via the discharge cylinder 37. Thereby, it becomes possible to deform | transform the deformation | transformation wall part 36 stably, and can aim at the further improvement of discharge accuracy.

また塗布栓14の先端部は、吐出筒37内に容器軸O方向に摺動自在に嵌合されているので、吐出筒37を塗布栓14の先端部に対して容器軸O方向に摺動させ、頂部34を容器軸O方向に安定して弾性変形させることができる。
さらに塗布栓14の外周面に、連通凹部41が設けられているので、計量筒部材13の頂部34が容器軸O方向に弾性変形して吐出筒37が塗布栓14の先端部に対して容器軸O方向に摺動したとしても、計量室29内を外部に安定して連通させることが可能になり、吐出精度の確実な向上を図ることができる。
Further, since the distal end portion of the application plug 14 is fitted in the discharge cylinder 37 so as to be slidable in the container axis O direction, the discharge cylinder 37 is slid in the container axis O direction with respect to the distal end portion of the application plug 14. The top 34 can be elastically deformed stably in the container axis O direction.
Further, since the communication recess 41 is provided on the outer peripheral surface of the coating plug 14, the top 34 of the measuring cylinder member 13 is elastically deformed in the container axis O direction, and the discharge cylinder 37 is a container with respect to the tip of the coating plug 14. Even if it slides in the direction of the axis O, the inside of the measuring chamber 29 can be stably communicated to the outside, and the discharge accuracy can be reliably improved.

また吐出筒37の先端部に、突出部40が周方向に間隔をあけて複数配置されているので、内容物の吐出時に、内容物を、周方向に隣り合う突出部40同士の間を通して被塗布部Sに塗布しつつ、計量筒部材13の頂部34の容器軸O方向への弾性変形をより安定させることができる。   Further, since a plurality of protrusions 40 are arranged at intervals in the circumferential direction at the distal end portion of the discharge cylinder 37, when the contents are discharged, the contents are covered between the protrusions 40 adjacent in the circumferential direction. While applying to the application part S, the elastic deformation of the top part 34 of the measuring cylinder member 13 in the container axis O direction can be further stabilized.
