Abstract

<P>PROBLEM TO BE SOLVED: To provide an application container capable of stably and surely realizing functions of keeping the inside of a container body sealed during real application operation even if a cap is opened and also supplying an application liquid only after the application operation starts. <P>SOLUTION: An inner plug member 3 is engaged with the mouth 21 of the container body 2, and an opening 311 is closed by a valve element 41 urged to close from a valve spring 42. A movable piece 55 is split by a thorough groove 521 extending along a full circumference from the upper surface wall 52 of an application member 5 engaged with the inner plug member, and in addition the movable piece is supported to be vertically displaceable by parallel movement by bellows-like supporting pieces 522 and 522. Reaction force working with the application operation onto a surface K for receiving the application is transmitted through brushes 51, 51, ..., resulting in displacement of the movable piece 55 to push the valve element 41 to open. Thus, supply of the application liquid starts from the container body 2. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、被塗布面に対し、先端の刷毛を介して容器本体内の液体又ゲル状等の塗布液を塗布するための塗布容器に関し、特に、キャップを開けても容器本体内は密封状態に維持され、塗布する際に初めて塗布液の供給を可能とする技術に係る。   The present invention relates to a coating container for applying a liquid or gel-like coating liquid in a container body to a surface to be coated through a brush at the tip, and in particular, the container body is sealed even when a cap is opened. The present invention relates to a technique that enables the supply of a coating liquid for the first time at the time of coating.

塗布容器として、従来、キャップを開けることで容器本体から刷毛に対する塗布液の供給が可能になるようにしたものが提案されている(例えば特許文献1又2参照)。このものでは、中栓部材に対しバネを介して塗布部材を上下動自在に装着し、キャップの閉操作により塗布部材を容器本体側に押し付けることで、中栓部材の開口が塗布部材に設けた栓体により閉状態に維持されるようにしたものであり、キャップを開操作すれば塗布部材がバネにより上動して中栓部材の開口が開かれるようにしている。   Conventionally, a coating container has been proposed in which a coating liquid can be supplied to a brush from a container body by opening a cap (see, for example, Patent Documents 1 and 2). With this, the application member is mounted on the inner plug member so as to be movable up and down via a spring, and the opening of the inner plug member is provided in the application member by pressing the application member against the container main body by closing the cap. The plug is maintained in a closed state, and when the cap is opened, the application member is moved upward by a spring so that the opening of the inner plug member is opened.

又、塗布部材を、可撓性を有するダイヤフラムと、このダイヤフラム上に植立させた刷毛とで構成し、ダイヤフラムで中栓部材や中栓部材の開口に内嵌させた弁体を覆うようにし、塗布操作時に被塗布面から受ける圧力によりダイヤフラムを変形させて弁体を開側に押し下げることで、容器本体から塗布液の供給を可能にしようとするものも提案されている(例えば特許文献3参照)。   Further, the coating member is composed of a flexible diaphragm and a brush planted on the diaphragm so that the diaphragm covers the inner plug member and the valve body fitted in the opening of the inner plug member. In addition, there has also been proposed a device that enables supply of a coating liquid from a container body by deforming a diaphragm by a pressure received from a surface to be coated during a coating operation and pushing down a valve body to an open side (for example, Patent Document 3). reference).

特開平11−138086号公報Japanese Patent Laid-Open No. 11-138086 特開2000−72171号公報JP 2000-72171 A 特開平11−319661号公報JP-A-11-319661

しかしながら、キャップを開けば塗布液が供給可能になるものでは、塗布容器が倒れると内部の塗布液が流出してしまうことになる一方、ダイヤフラムの変形で塗布液の供給を可能にしようとするものでは、実際の塗布操作が安定性・確実性に欠くものとなり、使い難いものになる、という不都合がある。   However, in the case where the application liquid can be supplied by opening the cap, the internal application liquid flows out when the application container falls down, while the deformation of the diaphragm makes it possible to supply the application liquid. However, there is an inconvenience that the actual coating operation lacks stability and certainty and is difficult to use.

すなわち、キャップを開けばバネで塗布部材が上動し、中栓部材の開口が開状態に変換されてしまうと、塗布操作の合間に仮置きした際などに倒れれば、内部の塗布液が開口から流出してしまうおそれがある。   That is, when the cap is opened, the application member is moved upward by a spring, and the opening of the inner plug member is converted to an open state. There is a risk of flowing out of the opening.

又、塗布操作に伴い被塗布面から受ける圧力(反力)でダイヤフラムを変形させ、この変形するダイヤフラムで弁体を押し下げて中栓部材の開口を開変換させようとするものでは、被塗布面からの圧力をダイヤフラムに伝達することになる刷毛はその圧力伝達に見合うようにある程度の硬さが必要である反面、ダイヤフラムはその圧力で弁体を押し下げられる程の軟らかさが必要であるというように相反する性能要求を満足させる必要があるにも拘わらず、ダイヤフラムや刷毛を共に柔軟性を有する同じ合成樹脂により一体成形しているというように、相反する性能要求を発揮し得ないおそれがある。この結果、現実の塗布操作においては、安定的かつ確実性のある使用性能が得られないおそれがある。   In addition, the diaphragm is deformed by the pressure (reaction force) received from the surface to be coated in accordance with the coating operation, and the valve body is pushed down by the deformed diaphragm to open the opening of the inner plug member. The brush that will transmit the pressure from the diaphragm to the diaphragm needs a certain degree of hardness to match the pressure transmission, but the diaphragm needs to be soft enough to push down the valve body with that pressure Although it is necessary to satisfy the performance requirements that conflict with each other, the diaphragm and the brush may not be able to fulfill the conflicting performance requirements, such as being integrally molded with the same flexible synthetic resin. . As a result, there is a risk that stable and reliable use performance cannot be obtained in an actual coating operation.

本発明は、このような事情に鑑みてなされたものであり、その目的とするところは、キャップを開いても容器本体内を密封状態に維持する一方、塗布操作に伴い初めて塗布液が供給可能になるという機能を、現実の塗布操作において安定的かつ確実に実現させ得る塗布容器を提供することにある。   The present invention has been made in view of such circumstances, and the object of the present invention is to maintain the inside of the container body in a sealed state even when the cap is opened, while the coating liquid can be supplied only after the coating operation. An object of the present invention is to provide an application container that can stably and reliably realize the function of becoming an actual application operation.

上記目的を達成するために、本発明は、塗布液を収容する容器本体と、上記容器本体の口部に係合されその口部を覆う隔壁の中央に開口を形成した中栓部材と、上記中栓部材の開口に対し下から上に内嵌するように中栓部材に内装され、弁バネ部からの上向きのバネ付勢力を受けて上記開口周縁の弁座に着座して閉弁され、閉弁状態でその頭部が上記開口から上側に突出する弁体部と、上記中栓部材に係合され上記弁体部の頭部を含んで上記中栓部材の開口を覆い刷毛が上向きに突出された上面壁を有する塗布部材と、塗布部材を覆って容器本体の口部に着脱可能に取り付けられるキャップとを備えることとする。そして、上記塗布部材として、上記上面壁の中央寄り部分であって上記刷毛が突出された部分が貫通溝により周囲と分断されその中央寄り位置に透孔が貫通された可動片と、上記可動片をその周囲において互いに離れた少なくとも2カ所又は全周にわたり上記上面壁と接続し上記弁体部との間で上下動可能に支持する支持片部とを備えて合成樹脂成形により一体に形成する。又、上記支持片として、上記弁体部に対し押圧力を伝達しない非伝達位置と、上記刷毛の先端からの押圧力を伝達して上記弁体部を上記バネ付勢力に抗して開弁状態に移動させる伝達位置との間に上記可動片を平行移動可能に支持するよう蛇腹状に形成する。さらに、上記弁バネ部として、そのバネ付勢力が、上記刷毛を被塗布面に押し当てた際に受ける反力の伝達を受けて上記可動片が上記伝達位置まで平行移動することにより上記弁体部を押し下げて上記開口を開弁させるように設定することとした(請求項1)。   In order to achieve the above object, the present invention provides a container main body that contains a coating liquid, an inner plug member that is engaged with a mouth portion of the container main body and that has an opening at the center of a partition wall that covers the mouth portion, It is built in the inner plug member so as to be fitted from the bottom to the upper side with respect to the opening of the inner plug member, receives the upward spring biasing force from the valve spring portion, is seated on the valve seat at the periphery of the opening, and is closed. A valve body with its head projecting upward from the opening in the valve-closed state, and a brush facing upwardly covering the opening of the inner plug member including the head of the valve body part engaged with the inner plug member An applicator member having a protruding upper wall and a cap that covers the applicator member and is detachably attached to the mouth of the container main body are provided. And as said application | coating member, the movable piece which the part near the center of the said upper surface wall and the part from which the said brush protruded was divided | segmented from the circumference | surroundings by the penetration groove | channel, and the through-hole penetrated the position near the center, The said movable piece And a support piece portion that is connected to the upper surface wall and is supported so as to move up and down between the valve body portion and at least two locations or the entire circumference apart from each other. Further, as the support piece, a non-transmission position that does not transmit the pressing force to the valve body part and a pressing force from the tip of the brush are transmitted to open the valve body part against the spring biasing force. The movable piece is formed in a bellows shape so as to be supported so as to be movable in parallel with the transmission position to be moved to a state. Furthermore, as the valve spring part, the valve biasing force receives the reaction force received when the brush is pressed against the surface to be coated, and the movable piece moves in parallel to the transmission position so that the valve element moves. The opening is opened by pushing down the part (Claim 1).

本発明の場合、正立状態の塗布容器からキャップを除去して塗布部材の刷毛を露出させても、中栓部材の開口は弁バネ部からのバネ付勢力を受けた弁体部により閉弁され、塗布容器は密封状態に維持されている。次に、塗布容器を倒立状態にし、下向きに延びる刷毛を被塗布面に押し当てると、刷毛に作用する被塗布面からの反力が可動片に伝達されて支持片部が湾曲することにより可動片が弁体部の側に変位し、可動片に押されて弁体部が開弁することになる。これにより、開口が開状態になって容器本体から塗布液が供給可能となる。この際、可動片が全周の貫通溝によって上面壁から分断された状態で支持片部によって変位可能に支持されている上に、弁バネ部が被塗布面に対する塗布操作により受ける反力によって弁体部を開弁させ得るようにバネ付勢力が設定されているため、塗布操作に伴い初めて塗布液が供給可能になるという機能を、現実の塗布操作において安定的かつ確実に実現させ得るようになる。つまり、塗布操作に伴い被塗布面からの反力を可動片に確実に伝達し得るように刷毛を比較的硬めの合成樹脂により形成すると共に、その同じ合成樹脂を用いて塗布部材全体を一体形成することが可能となり、そのようにしたとしても、上記反力により刷毛が座屈を生じて有効に反力を伝達し得なくなる事態を回避して、可動片に対し反力を有効に伝達させて可動片の変位及び弁体部の開弁作動を生じさせることが可能となる。   In the case of the present invention, even if the cap is removed from the coating container in the upright state to expose the brush of the coating member, the opening of the inner plug member is closed by the valve body portion that receives the spring biasing force from the valve spring portion. The application container is maintained in a sealed state. Next, when the coating container is turned upside down and a downwardly extending brush is pressed against the surface to be coated, the reaction force from the surface to be coated acting on the brush is transmitted to the movable piece and the support piece is curved to move. The piece is displaced to the side of the valve body portion, and is pushed by the movable piece to open the valve body portion. As a result, the opening is opened and the coating liquid can be supplied from the container body. At this time, the movable piece is supported by the support piece portion so as to be displaceable in a state where the movable piece is separated from the upper surface wall by the through-grooves on the entire circumference, and the valve spring portion is subjected to the reaction force received by the coating operation on the coated surface. Since the spring biasing force is set so that the body part can be opened, the function that the coating liquid can be supplied only after the coating operation can be realized stably and reliably in the actual coating operation. Become. In other words, the brush is formed of a relatively hard synthetic resin so that the reaction force from the coated surface can be reliably transmitted to the movable piece during the coating operation, and the entire coating member is integrally formed using the same synthetic resin. Even if this is done, the reaction force effectively transmits the reaction force to the movable piece by avoiding the situation where the reaction force causes the brush to buckle and cannot effectively transmit the reaction force. Thus, the displacement of the movable piece and the valve opening operation of the valve body can be caused.

又、本発明において、上記弁バネ部として、上記弁体部と、この弁体部の下方位置で上記中栓部材により支持される支持環との両者間において螺旋状に延びて両者を互いに結合させる複数の帯状バネ片を備えて構成することができる(請求項2)。このようにすることにより、弁バネ部を容易に合成樹脂成形によって形成することが可能となる上に、その螺旋の傾斜、本数や肉厚等を調整することによりバネ付勢力の程度を容易に所望のものに調整することが可能となる。このため、弁バネ部を含め全てを合成樹脂成形により形成したとしても、非操作時に弁体部を確実に閉弁状態に維持し得るバネ付勢力を発揮し得る一方、塗布操作時には弁体部を確実に開弁作動させ得るようになる。   Further, in the present invention, as the valve spring portion, the valve body portion and a support ring supported by the inner plug member at a position below the valve body portion are spirally extended to couple the two together. A plurality of strip-shaped spring pieces can be provided (claim 2). In this way, the valve spring can be easily formed by synthetic resin molding, and the degree of spring biasing force can be easily adjusted by adjusting the inclination, number, thickness, etc. of the spiral. It becomes possible to adjust to a desired one. For this reason, even if it is formed entirely by synthetic resin molding including the valve spring part, it can exert a spring biasing force that can reliably keep the valve body part closed during non-operation, while the valve body part during application operation Can be reliably opened.

さらに、本発明において、上記中栓部材を容器本体の口部に対し、上記塗布部材を上記中栓部材に対し、それぞれ上から被せることで引き抜けが阻止された状態に互いに係合可能となる構成とし、加えて、少なくとも塗布部材を、その外周囲から外周側に突出する凸状係止部がキャップの内周面から内周側に突出する保持凸部をキャップの下端開口側から内奥に向けて乗り越えることで上記キャップ内に一体的に仮保持可能となる構成とすることができる(請求項3)。このように塗布部材をキャップ内に一体的に仮保持させることにより、塗布部材から突出する刷毛がキャップ内に遮蔽されて保護された状態になるため、容器本体に塗布液を充填した後に組み付けラインにて塗布部材を組み付ける際に生じるおそれのある刷毛の損傷の発生を確実に回避させることが可能となる。これにより、塗布容器に塗布液を充填して製品化するラインでの不良品除去工数等の削減や歩留まりの可及的な改善を図り得ることになる。   Furthermore, in the present invention, the inner plug member can be engaged with the mouth portion of the container main body, and the coating member can be engaged with the inner plug member from above so as to be prevented from being pulled out. In addition, at least the coating member has a convex locking portion protruding from the outer periphery to the outer peripheral side, and a holding convex portion protruding from the inner peripheral surface of the cap to the inner peripheral side. It can be set as the structure which can be temporarily hold | maintained integrally in the said cap by getting over toward (Claim 3). Since the brush protruding from the coating member is shielded and protected in the cap by temporarily holding the coating member integrally in the cap in this way, the assembly line is filled after the container body is filled with the coating liquid. Thus, it is possible to reliably avoid the occurrence of brush damage that may occur when the application member is assembled. As a result, it is possible to reduce the number of defective product removal man-hours and improve the yield as much as possible in a line that fills a coating container with a coating solution to produce a product.

この場合、さらに、上記キャップの内奥位置に、このキャップ内に仮保持された状態の上記塗布部材の内奥側の部位に当接することで、その塗布部材のそれ以上の内奥側への移動を規制するストッパを形成することができる(請求項4)。このようにすることにより、塗布液充填後にキャップを閉じる工程までは塗布部材を保持凸部とストッパとで挟み込んで正確に位置決めした状態に仮保持し得る一方、キャップを閉じる工程においてはキャップを閉操作するだけで、その閉操作力が内部に仮保持された塗布部材に対しストッパを介して組み付け力として伝達され、この組み付け力によって塗布部材が中栓部材に対し係合されて組み付けられることになる。これにより、キャップを閉じる工程を実行することによって塗布部材をも同時にかつ確実に組み付けることが可能となる。   In this case, further, by contacting the inner part of the application member in the state of being temporarily held in the cap at the inner inner position of the cap, the application member is further inwardly exposed. A stopper for restricting the movement can be formed (claim 4). By doing so, the coating member can be temporarily held in a state of being accurately positioned by being sandwiched between the holding convex portion and the stopper until the step of closing the cap after filling the coating liquid, while the cap is closed in the step of closing the cap. By simply operating, the closing operation force is transmitted as an assembly force to the application member temporarily held inside through the stopper, and the application member is engaged and assembled with the inner plug member by this assembly force. Become. Thereby, it becomes possible to assemble the application member simultaneously and reliably by executing the step of closing the cap.

以上、説明したように、本発明の塗布容器によれば、正立状態の塗布容器からキャップを開操作して除去して塗布部材の刷毛を露出させても、中栓部材の開口は弁バネ部からのバネ付勢力を受けた弁体部により閉弁されているため、塗布容器を密封状態に維持させることができる。その一方、塗布容器を倒立状態にし、下向きに延びる刷毛を被塗布面に押し当てる塗布操作を行うと、刷毛に作用する被塗布面からの反力によって可動片を変位させて弁体部を開弁させることができ、容器本体から塗布液を供給させることができるようになる。この際、可動片を全周に亘る貫通溝によって上面壁から分断して支持片部によって変位可能に支持している上に、弁バネ部のバネ付勢力を被塗布面に対する塗布操作により受ける反力によって弁体部を開弁させるように設定しているため、塗布操作に伴い初めて塗布液が供給可能になるという機能を、現実の塗布操作において安定的かつ確実に実現させることができるようになる。つまり、塗布操作に伴い被塗布面からの反力を可動片に確実に伝達し得るように刷毛を比較的硬めの合成樹脂により形成すると共に、その同じ合成樹脂を用いて塗布部材全体を一体形成することができ、そのようにしたとしても、上記反力により刷毛が座屈を生じて有効に反力を伝達し得なくなる事態を回避して、可動片に対し反力を有効に伝達させて可動片の変位及び弁体部の開弁作動を生じさせることができるようになる。   As described above, according to the applicator container of the present invention, even if the cap is opened from the applicator container in an upright state and removed to expose the brush of the applicator member, the opening of the inner plug member remains the valve spring. Since the valve body is closed by the spring biasing force from the portion, the application container can be maintained in a sealed state. On the other hand, when an application operation is performed in which the application container is turned upside down and a downwardly extending brush is pressed against the application surface, the movable piece is displaced by the reaction force from the application surface acting on the brush to open the valve body. Thus, the coating liquid can be supplied from the container body. At this time, the movable piece is separated from the upper surface wall by a through groove extending over the entire circumference and supported by the support piece portion so as to be displaceable, and the spring biasing force of the valve spring portion is applied by a coating operation on the coated surface. Since the valve body is set to open by force, the function that the coating liquid can be supplied only after the coating operation can be realized stably and reliably in the actual coating operation. Become. In other words, the brush is formed of a relatively hard synthetic resin so that the reaction force from the coated surface can be reliably transmitted to the movable piece during the coating operation, and the entire coating member is integrally formed using the same synthetic resin. Even if it does so, it avoids the situation where the brush is buckled by the reaction force and cannot effectively transmit the reaction force, and the reaction force is effectively transmitted to the movable piece. It becomes possible to cause displacement of the movable piece and valve opening operation of the valve body.

特に、請求項2によれば、上記弁バネ部として、螺旋状に延びて両者を互いに結合させる複数の帯状バネ片を備えて構成することにより、弁バネ部を容易に合成樹脂成形によって形成することができるようになる上に、その螺旋の傾斜、本数や肉厚等を調整することによりバネ付勢力の程度を容易に所望のものに調整することができるようになる。このため、弁バネ部を含め全てを合成樹脂成形により形成したとしても、非操作時に弁体部を確実に閉弁状態に維持し得るバネ付勢力を発揮させることができる一方、塗布操作時には弁体部を確実に開弁作動させることができるようになる。   In particular, according to the second aspect of the present invention, the valve spring portion is configured by including a plurality of strip-shaped spring pieces that extend in a spiral shape and couple them together, thereby easily forming the valve spring portion by synthetic resin molding. In addition, the degree of the spring biasing force can be easily adjusted to a desired value by adjusting the inclination, number, thickness, etc. of the spiral. For this reason, even if all of the valve spring part including the valve spring part is formed by synthetic resin molding, it is possible to exert a spring urging force that can reliably keep the valve body part closed when not operated, The body part can be reliably opened.

さらに、請求項3によれば、凸状係止部と保持凸部とによって、塗布部材をキャップ内に一体的に仮保持させることができるようなり、このようにすることにより、塗布部材から突出する刷毛をキャップ内に遮蔽して保護することができる。このため、容器本体に塗布液を充填した後に組み付けラインにて塗布部材を組み付ける際に生じるおそれのある刷毛の損傷の発生を確実に回避させることができる。これにより、塗布容器に塗布液を充填して製品化するラインでの不良品除去工数等の削減や歩留まりの可及的な改善を図ることができるようになる。   Further, according to the third aspect, the projecting locking portion and the holding projecting portion allow the application member to be temporarily held integrally in the cap. The brush to be shielded can be shielded and protected in the cap. For this reason, it is possible to reliably avoid occurrence of damage to the brush that may occur when the application member is assembled in the assembly line after the container body is filled with the coating liquid. As a result, it is possible to reduce the number of defective product removal man-hours and the like and improve the yield as much as possible in a line for filling the coating container with the coating liquid to produce a product.

この場合において、請求項4によれば、塗布液充填後にキャップを閉じる工程までは塗布部材を保持凸部とストッパとで挟み込んで正確に位置決めした状態に仮保持することができる一方、キャップを閉じる工程においてはキャップを閉操作するだけで、その閉操作力が内部に仮保持された塗布部材に対しストッパを介して組み付け力として伝達させることができ、この組み付け力によって塗布部材を中栓部材に対し係合させて組み付けることができるようになる。これにより、キャップを閉じる工程を実行することによって塗布部材をも同時にかつ確実に組み付けることができるようになる。   In this case, according to the fourth aspect, until the step of closing the cap after filling the coating liquid, the application member can be temporarily held in a state of being accurately positioned by being sandwiched between the holding convex portion and the stopper, while the cap is closed. In the process, just by closing the cap, the closing operation force can be transmitted as an assembly force to the application member temporarily held inside through the stopper, and the application force is applied to the inner plug member by this assembly force. It becomes possible to engage and assemble. Thereby, the application member can be assembled at the same time and reliably by executing the step of closing the cap.

容器本体2はその口部21側にかけて段階的に縮径され、口部21は少なくともキャップ6の螺合ネジ22よりも小径の筒部に形成され、口部21の開口縁近傍にはその外周面に係合凸部23が突出して形成されている。   The container body 2 is gradually reduced in diameter toward the mouth portion 21, and the mouth portion 21 is formed in a cylindrical portion having a diameter smaller than that of the screw 6 of the cap 6. An engaging projection 23 is formed on the surface so as to protrude.

中栓部材3は、容器本体2の口部21を覆う隔壁31と、隔壁31の外周位置から下向き(口部21の外周面側)に僅かに突出する下側係合筒部32と、上記口部21の内径に対応する外径を有し内部にバネ付き弁体4を収容し得るように下向きに所定量だけ突出する収容筒部33と、隔壁31の上面から上向きに僅かに突出する上側係合筒部34とを備えて構成されている。隔壁31の中央位置(中心位置)には上下方向(内外方向)に貫通して供給口となる開口311(図4も併せて参照)が形成され、この開口311の下側範囲に下向き斜面を有する弁座312が形成されている。隔壁31の上面は開口311が最下位になるようにすり鉢状の斜面により構成され、上側係合筒部34の内周面及び塗布部材5の後述の内周筒部54の内周面により塗布操作時の塗布液の外周側への漏れや飛散を阻止し、かつ、塗布操作終了後に塗布容器を正立状態に戻した際に余剰の塗布液を自動的に開口311の側に導き得るようになっている。下側係合筒部32の内周面には口部21の係合凸部23と互いに係合して上下方向に対する組み付け固定が可能な係合凸部321が突出して形成され、収容筒部33の下端開口縁331には内周側に突出してバネ付き弁体4の後述の支持環421を当て止めて支持する支持段部332が形成され、上側係合筒34の外周面には塗布部材5の後述の係合凸部531と互いに係合する係合凸部341が形成されている。   The inner plug member 3 includes a partition wall 31 that covers the mouth portion 21 of the container body 2, a lower engagement cylinder portion 32 that slightly protrudes downward (outer peripheral surface side of the mouth portion 21) from the outer peripheral position of the partition wall 31, An accommodating cylinder portion 33 having an outer diameter corresponding to the inner diameter of the mouth portion 21 and projecting downward by a predetermined amount so that the spring-loaded valve element 4 can be accommodated therein, and slightly projecting upward from the upper surface of the partition wall 31. The upper engagement cylinder portion 34 is provided. An opening 311 (see also FIG. 4) is formed in the central position (center position) of the partition wall 31 so as to penetrate in the vertical direction (inward and outward direction) and serve as a supply port. A downward slope is formed in a lower range of the opening 311. A valve seat 312 is formed. The upper surface of the partition wall 31 is constituted by a mortar-shaped slope so that the opening 311 is at the lowest position, and is applied by the inner peripheral surface of the upper engaging cylinder portion 34 and the inner peripheral surface of the inner peripheral cylinder portion 54 described later of the application member 5. It is possible to prevent leakage and scattering of the coating liquid to the outer peripheral side during operation, and to automatically guide the excess coating liquid to the opening 311 side when the coating container is returned to the upright state after the coating operation is completed. It has become. On the inner peripheral surface of the lower side engagement cylinder part 32, an engagement projection part 321 that is engaged with the engagement projection part 23 of the mouth part 21 and can be assembled and fixed in the vertical direction protrudes and is formed. The lower end opening edge 331 of 33 is formed with a support step 332 that protrudes to the inner peripheral side and supports and supports a later-described support ring 421 of the spring-loaded valve body 4, and is applied to the outer peripheral surface of the upper engagement cylinder 34. An engaging convex portion 341 that engages with an engaging convex portion 531 described later of the member 5 is formed.

バネ付き弁体4は、開口311に対し下から上に内嵌する弁体部41と、この弁体部41を弁座312に対し上向きに押し付けて閉側付勢する弁バネ部42とが合成樹脂により一体成形されたものである。弁体部41はその基部外周面に上記弁座312に密着し得る上向き斜面により構成された弁部411を備え、かつ、閉弁状態で開口311よりも上方に突出する頭部412を備えている。弁バネ部42は、上記の支持段部332の内径よりも僅かに大径の外径を有する支持環421と、支持環421及び弁体部41の間において螺旋状に延びて両者を結合させる複数(図例では3本)の帯状バネ片422,422,…とを備えて構成されている。   The valve body 4 with the spring includes a valve body portion 41 that is fitted into the opening 311 from the bottom to the top, and a valve spring portion 42 that presses the valve body portion 41 upward against the valve seat 312 to urge the valve body 312 to close. It is integrally molded with a synthetic resin. The valve body portion 41 includes a valve portion 411 configured by an upward inclined surface that can be in close contact with the valve seat 312 on the outer peripheral surface of the base portion, and a head portion 412 that protrudes above the opening 311 in a valve-closed state. Yes. The valve spring portion 42 spirally extends between the support ring 421 having an outer diameter slightly larger than the inner diameter of the support step portion 332 and between the support ring 421 and the valve body portion 41 to couple them together. A plurality (three in the illustrated example) of belt-like spring pieces 422, 422,...

そして、中栓部材3の弁座312から支持段部332上面までの上下間隔Hnが、バネ付き弁体4の弁部411から支持環421下端までの自由状態(開放状態)における上下寸法Hsよりも所定量短く設定されており、バネ付き弁体4を中栓部材3の下端開口331から上向きに挿入して弁部411を弁座312に着座させ(図3又は図4参照)、さらに圧入させるように押し込んで支持環421を支持段部332の上面に係合させる。この状態では帯状バネ片422,422,…の上下方向寸法が強制的に縮められて外周方向に撓む結果、帯状バネ片422,422,…から弁体部41に対し弁体部41を弁座312に押し付けるように上向きのバネ付勢力が作用した状態になる。これにより、中栓部材3の開口311は閉側にバネ付勢された弁体部41で閉状態に維持されることになる。   The vertical distance Hn from the valve seat 312 of the inner plug member 3 to the upper surface of the support step 332 is higher than the vertical dimension Hs in the free state (open state) from the valve part 411 of the spring-loaded valve body 4 to the lower end of the support ring 421. Also, the spring-loaded valve element 4 is inserted upward from the lower end opening 331 of the inner plug member 3 to seat the valve part 411 on the valve seat 312 (see FIG. 3 or FIG. 4), and further press-fitted Then, the support ring 421 is engaged with the upper surface of the support step 332. In this state, the vertical dimension of the strip-shaped spring pieces 422, 422,... Is forcibly contracted and bent in the outer peripheral direction, so that the valve-body portion 41 is moved from the strip-shaped spring pieces 422, 422,. An upward spring biasing force is applied so as to press against the seat 312. As a result, the opening 311 of the inner plug member 3 is maintained in the closed state by the valve body 41 spring-biased to the closed side.

上記の螺旋状に延びる各帯状バネ片422,422,…は、その螺旋の傾斜、帯状バネ片422の本数やその肉厚等を調整することにより弁体部41に対する閉側のバネ付勢力の程度を容易に調整することができ、後述の如き塗布操作に伴い被塗布面K(図9又は図10参照)からの反力の伝達に基づき弁体部41を開弁作動させ得るように、そのバネ付勢力が調整・設定されている。これにより、塗布操作時の被塗布面Kからの反力に基づき容器本体2からの塗布液の供給開始を確実に実現させることができるようになる。   Each of the strip-like spring pieces 422, 422,... Extending in a spiral shape has a spring biasing force on the closing side with respect to the valve body 41 by adjusting the inclination of the spiral, the number of the strip-like spring pieces 422, the thickness thereof, and the like. The degree can be easily adjusted, and the valve body 41 can be opened based on the reaction force transmitted from the coated surface K (see FIG. 9 or 10) in accordance with the coating operation as described below. The spring biasing force is adjusted and set. Thereby, the supply start of the coating liquid from the container body 2 can be reliably realized based on the reaction force from the coated surface K during the coating operation.

塗布部材5(図5も併せて参照)は、(刷毛51,51,…と、これら刷毛51,51,…の根本が結合され)中栓部材3や弁体部41を覆う上面壁52と、上面壁52の外周側に結合される外周筒部53と、上面壁52の上記外周筒部53よりも内周側の下面位置から突出する内周筒部54とを備えて構成されている。上面壁52は、その中央寄りの領域であって所定径の円形領域が図2又は図5に示すように全周に延びるスリット状貫通溝521により区画・分断されて可動片55とされ、この可動片55はその直径方向両端部の2箇所において支持片部522,522によって上面壁52に対し接続されている。各支持片部522は、貫通溝521を跨いで上向きに凸に屈曲するよう蛇腹状に形成され、これにより、可動片55を外力(例えば、後述の非塗布面Kからの反力)の伝達や作用を受けない自由状態における非伝達位置(図2に示す位置参照)と、被塗布面Kからの反力の伝達を受けて平行移動して弁体部41を開弁状態まで押圧する伝達位置(図9又は図10に示す位置参照)との間を弾性に基づき変位可能に支持するようになっている。   The applicator member 5 (see also FIG. 5) (the brushes 51, 51,... And the roots of the brushes 51, 51,... Are combined) and the upper wall 52 covering the inner plug member 3 and the valve body 41 The outer peripheral cylindrical portion 53 coupled to the outer peripheral side of the upper surface wall 52 and the inner peripheral cylindrical portion 54 protruding from the lower surface position on the inner peripheral side of the outer peripheral cylindrical portion 53 of the upper surface wall 52 are configured. . The upper surface wall 52 is a region near the center, and a circular region having a predetermined diameter is partitioned and divided by a slit-like through groove 521 extending around the entire circumference as shown in FIG. 2 or FIG. The movable piece 55 is connected to the upper surface wall 52 by support piece portions 522 and 522 at two locations on both ends in the diameter direction. Each support piece 522 is formed in a bellows shape so as to bend upward and project across the through-groove 521, thereby transmitting an external force (for example, a reaction force from a non-application surface K described later) to the movable piece 55. And a non-transmission position in a free state where no action is received (refer to the position shown in FIG. 2) and a transmission that receives the reaction force from the coated surface K and moves in parallel to press the valve body 41 to the valve-open state. Between the positions (refer to the positions shown in FIG. 9 or FIG. 10), it is supported to be displaceable based on elasticity.

可動片55の中央寄り位置には透孔551が貫通形成され、この透孔551を囲むように刷毛51,51,…が適宜間隔で上向きに突出するよう立設されている。各刷毛51は可動片55の上面から互いに平行に上向きに延び、例えば先端にいくほど細径になるように形成されたもので、合成樹脂による一体成形により可動片55と一体に形成されている。なお、一体成形の他に、各刷毛51を直毛等の他の手段によりその根元を可動片55に結合させるようにすることも可能である。又、可動片55の下面にはストッパとして例えば下向きに突出する筒状の脚部552が形成されている。この脚部552は、後述の如く可動片55の伝達位置側(図2の下方位置側)への変位の際に、過度の変位が生じれば脚部552の下端が中栓部材3の隔壁31の上面に当接することにより、可動片55の過度の変位を抑制するためのストッパとしての役割を果たすようになっている。   A through hole 551 is formed at a position near the center of the movable piece 55, and the brushes 51, 51,... Stand up so as to protrude upward at appropriate intervals so as to surround the through hole 551. Each brush 51 extends upward in parallel with each other from the upper surface of the movable piece 55 and is formed to have a smaller diameter toward the tip, for example, and is integrally formed with the movable piece 55 by integral molding with synthetic resin. . In addition to integral molding, it is also possible to connect each brush 51 to the movable piece 55 by other means such as straight hair. Further, a cylindrical leg portion 552 that protrudes downward, for example, is formed on the lower surface of the movable piece 55 as a stopper. As will be described later, when the leg 552 is displaced excessively when the movable piece 55 is displaced toward the transmission position (the lower position in FIG. 2), the lower end of the leg 552 is the partition wall of the inner plug member 3. By abutting on the upper surface of 31, it plays a role as a stopper for suppressing excessive displacement of the movable piece 55.

外周筒部53と内周筒部54との間隔はこれら両者間に対し中栓部材3の上側係合筒部34が内嵌し得るように設定され、外周筒部53の内周面には上側係合筒部34の係合凸部341と互いに係合して上下方向に対する組み付け固定が可能な係合凸部531が突出して形成されている。加えて、外周筒部53の外周面には凸状係止部として少なくとも3つ以上(図例では8つ)の係止突起532,532,…(特に図2及び図5参照)が外周側に突出するように形成されている。この係止突起532,532,…は、キャップ6の後述の保持凸部63を乗り越えて係止されることにより、塗布部材5をキャップ6内に一体的に組み付けた状態に保持し得るようになっている。   The interval between the outer peripheral cylindrical portion 53 and the inner peripheral cylindrical portion 54 is set so that the upper engaging cylindrical portion 34 of the inner plug member 3 can be fitted between the two. An engaging convex portion 531 that is engaged with the engaging convex portion 341 of the upper engaging cylindrical portion 34 and can be assembled and fixed in the vertical direction protrudes. In addition, at least three (eight in the illustrated example) locking projections 532, 532,... (See particularly FIGS. 2 and 5) are provided on the outer peripheral side as convex locking portions on the outer peripheral surface of the outer peripheral cylindrical portion 53. It is formed so as to protrude. The locking projections 532, 532,... Can be held over a later-described holding convex portion 63 of the cap 6 so as to be able to hold the application member 5 in an integrally assembled state in the cap 6. It has become.

キャップ6は、頂壁と周壁とから下方に開口し、上から中栓部材3や塗布部材5に被せてこれらを内部に収容した状態で、下端側の内周面のネジ部61により容器本体2の口部21のネジ部22にねじ込まれるようになっている。又、キャップ6は、その頂壁の下面から下向きに突出したストッパとしての筒部62を備え、筒部62の下端が上記の一体的組み付け状態における塗布部材5の上面壁52の外周側位置に当接可能となっている。さらに、キャップ6の上下方向の所定の中間位置には滑らかなカーブを描いて内周側に突出する保持凸部63(図6も併せて参照)が全周に亘り形成されている。この保持凸部63は、塗布容器内に塗布液が充填されるまでは塗布部材5をキャップ6内に一体的に組み付け保持しておくことができる一方、製品として使用者が使用する際には塗布部材5を中栓部材3に対し組み付けたままで、キャップ6を開閉操作し得るようにするものである。   The cap 6 opens downward from the top wall and the peripheral wall, covers the inner plug member 3 and the coating member 5 from above and accommodates them inside, and the container main body by the screw portion 61 on the inner peripheral surface on the lower end side. The screw portion 22 of the second mouth portion 21 is screwed. Further, the cap 6 includes a cylindrical portion 62 as a stopper protruding downward from the lower surface of the top wall, and the lower end of the cylindrical portion 62 is positioned at the outer peripheral side position of the upper surface wall 52 of the application member 5 in the integrally assembled state. Contact is possible. Further, a holding convex portion 63 (see also FIG. 6) is formed over the entire circumference at a predetermined intermediate position in the vertical direction of the cap 6 so as to draw a smooth curve and project toward the inner peripheral side. The holding projection 63 can integrally hold the application member 5 in the cap 6 until the application liquid is filled in the application container. On the other hand, when the user uses the product as a product, The cap 6 can be opened and closed while the application member 5 is attached to the inner plug member 3.

すなわち、図6に示すようにキャップ6の下端開口から塗布部材5を挿入していくと、図7(a)に示すように外周囲の各係止突起532が保持凸部63の下側に当たり、なおも塗布部材5を押し込んでいくと、各係止突起532が弾性変形して保持凸部63を乗り越え、乗り越えることにより各係止突起532が復元し、塗布部材5は保持凸部63の上側位置でキャップ6の内周面に保持されることになる。この際、上記の筒部62は、各係止突起532が保持凸部63を乗り越えることにより塗布部材5の上面壁52の上面と当接し(図6参照)、これ以上の塗布部材5の押し込みを規制することになる。加えて、筒部62が当接して塗布部材5のそれ以上の押し込み側移動が阻止されるため、後述の如く塗布液充填後にキャップ6と共に塗布部材5を中栓部材3に組み付ける際には、キャップ6を容器本体2の側に押し込めば、塗布部材5の外周筒部53と内周筒部54の間に中栓部材3の上側係合筒部34が圧入気味に押し入れられて、両者の係合凸部531,341を確実に係合させ得るようになっている。すなわち、上記筒部62は、塗布液充填後の閉キャッピング工程までは保持凸部63と共に塗布部材5をキャップ6内の所定位置に対し正確に位置決めした状態に仮保持するストッパとしての役割を果たす一方、閉キャッピング工程においてはキャップ6に加えられる閉操作力を塗布部材5に対し中栓部材3への組み付け力として伝達する組み付け力伝達部材としての役割を果たすことになる。   That is, when the application member 5 is inserted from the lower end opening of the cap 6 as shown in FIG. 6, the outer peripheral locking projections 532 hit the lower side of the holding projection 63 as shown in FIG. As the application member 5 is pushed further in, the respective locking projections 532 are elastically deformed and get over the holding projections 63, and by moving over, the respective locking projections 532 are restored. It is held on the inner peripheral surface of the cap 6 at the upper position. At this time, the cylindrical portion 62 comes into contact with the upper surface of the upper surface wall 52 of the coating member 5 as each locking projection 532 gets over the holding projection 63 (see FIG. 6), and the coating member 5 is pushed further. Will be regulated. In addition, since the cylinder portion 62 abuts and further pushing side movement of the coating member 5 is prevented, when the coating member 5 is assembled to the inner plug member 3 together with the cap 6 after filling the coating solution as described later, If the cap 6 is pushed into the container main body 2 side, the upper engagement cylinder portion 34 of the inner plug member 3 is pushed in between the outer peripheral cylinder portion 53 and the inner peripheral cylinder portion 54 of the application member 5, The engaging projections 531 and 341 can be reliably engaged. That is, the cylindrical portion 62 serves as a stopper that temporarily holds the application member 5 together with the holding convex portion 63 in a state where the application member 5 is accurately positioned with respect to a predetermined position in the cap 6 until the capping step after the application liquid is filled. On the other hand, in the closed capping step, it plays a role as an assembly force transmission member that transmits the closing operation force applied to the cap 6 as an assembly force to the inner plug member 3 to the application member 5.

一方、塗布液充填後、製品として出荷されて使用者が塗布操作する際には、キャップ6を開操作しても、塗布部材5は中栓部材3の側、つまり容器本体2の側に組み付けられた状態に維持され、この状態でキャップ6の繰り返しの開閉操作が可能となる。すなわち、図7(b)に示すように、塗布部材5の係合凸部531と中栓部材3の係合凸部341とが互いに係合された後は、上下方向への引き抜き力に対しては強固な係合状態になっているため、キャップ6を開くために上向きにネジって開操作したとしても、キャップ6の保持凸部63が図7(b)の実線から一点鎖線へ、さらに一点鎖線から二点鎖線へと係止突起532を折り曲げて上向きに移動し、移動キャップ6が上向きに移動するだけで、塗布部材5は中栓部材3に組み付けられた状態に維持される。逆にキャップ6を下向きにネジって閉操作したとしても、上記とは逆に保持凸部63が係止突起532を折り曲げて下向きに移動して元の閉状態に戻ることになる。これがキャップ6の開閉操作の度に繰り返されることになる。   On the other hand, when the user performs a coating operation after filling with the coating liquid, even if the cap 6 is opened, the coating member 5 is assembled to the inner plug member 3 side, that is, the container body 2 side. The cap 6 is repeatedly opened and closed in this state. That is, as shown in FIG. 7B, after the engaging convex portion 531 of the coating member 5 and the engaging convex portion 341 of the inner plug member 3 are engaged with each other, the pulling force in the vertical direction is not affected. Therefore, even if the cap 6 is opened upward by twisting to open the cap 6, the holding convex portion 63 of the cap 6 changes from the solid line in FIG. Further, the locking protrusion 532 is bent from the one-dot chain line to the two-dot chain line and moved upward, and the application member 5 is maintained in the state assembled to the inner plug member 3 only by moving the moving cap 6 upward. On the contrary, even if the cap 6 is screwed downward and closed, the holding convex portion 63 bends the locking projection 532 and moves downward to return to the original closed state. This is repeated every time the cap 6 is opened and closed.

上記の保持凸部63の形成位置は次のように設定すればよい。すなわち、容器本体2に対し中栓部材3を組み付け、この中栓部材に対し塗布部材5を組み付けた状態(図2参照)における塗布部材5と、容器本体2の口部21のネジ部22に最終の閉位置までねじ込まれた状態におけるキャップ6との間で、塗布部材5とキャップ6とが互いの相対位置を維持して保持されるように、保持凸部63の形成位置を設定すればよい。そして、このような相対位置を維持した状態で、キャップ6の筒部62が塗布部材5の上面壁52に略当接することになる。   What is necessary is just to set the formation position of said holding | maintenance convex part 63 as follows. That is, the inner plug member 3 is assembled to the container body 2, and the application member 5 in the state where the application member 5 is assembled to the inner plug member (see FIG. 2) and the screw portion 22 of the mouth portion 21 of the container body 2. If the formation position of the holding convex portion 63 is set so that the application member 5 and the cap 6 are held while maintaining the relative position between the cap 6 in the state screwed to the final closed position. Good. In addition, the cylindrical portion 62 of the cap 6 substantially comes into contact with the upper surface wall 52 of the application member 5 while maintaining such a relative position.

次に、以上のような塗布部材の製品として出荷されるまでの工程を説明すると、次のようになる。一般に、塗布容器自体を製造する容器メーカから、内部に充填する塗布液を製造する薬品メーカに対し、塗布容器を構成する構成要素毎にバラバラにした状態で運送され、薬品メーカにおいて容器本体に塗布液を充填した後に、同じ薬品メーカにて全ての構成要素が組み付けられて製品として出荷されることになる。   Next, the process up to shipping as a product of the application member as described above will be described as follows. Generally, from the container manufacturer that manufactures the coating container itself to the chemical manufacturer that manufactures the coating liquid to be filled inside, it is transported in a state where each component constituting the coating container is separated and applied to the container body at the pharmaceutical manufacturer. After filling the liquid, all the components are assembled and shipped as a product by the same chemical manufacturer.

しかしながら、このように構成要素を構成要素毎にまとめて薬品メーカに納入した場合には、薬品メーカでの塗布液充填工程の後の組み付け工程において、特に刷毛の部分に破損を招くおそれが考えられる。すなわち、自動処理により組み付ける際に、一般に、刷毛部分が形成された多数個のパーツをパーツフィーダに投入し、このパーツフィーダでの振動付与によりそのパーツを例えば倒立状態に整列させることになるものの、このパーツフィーダによる整列の際にパーツ同士の衝突により刷毛部分に曲がりや絡み合いが生じたり、破損を招いたりする可能性が高くなるという問題を抱えている。このことは、損傷を受けたパーツの組み付けラインからの除去作業に伴う手間の増加や、歩留まりの低下という大きな問題を招くことにもなる。   However, in the case where the constituent elements are collectively delivered to the chemical manufacturer in this way, there is a possibility that the brush portion is particularly damaged in the assembly process after the coating liquid filling process in the chemical manufacturer. . That is, when assembling by automatic processing, generally, a large number of parts with a brush portion formed are put into a parts feeder, and the parts are aligned, for example, in an inverted state by applying vibration with this parts feeder. When aligning with the parts feeder, there is a problem that there is a high possibility that the brush part will be bent or entangled due to collision between parts, or that damage will be caused. This also leads to a large problem of an increase in labor associated with the removal work of the damaged parts from the assembly line and a decrease in yield.

本実施形態の場合、構成要素(構成部品)としては容器本体2、中栓部材3、バネ付き弁体4、塗布部材5及びキャップ6の5点となるが、図8に示すように3点の構成要素に削減し、3点にした構成要素を薬品メーカに納入し、薬品メーカでは塗布液充填後に容器本体2に対し他の2点の構成要素を組み付ける、というようにして、刷毛51,51,…の確実な保護のみならず、組み付け工数の大幅な削減を実現させている。すなわち、容器メーカにおいて、バネ付き弁体4を中栓部材3に(図8参照)、塗布部材5をキャップ6に、それぞれ予め一体的に組み付けて、構成要素として容器本体2と、バネ付き弁体4を内装した中栓部材3と、塗布部材5が仮保持されたキャップ6との3点にし、この状態で薬品メーカに納入する。薬品メーカでは、容器本体2に塗布液を充填した後、まず、バネ付き弁体4を内装した中栓部材3を容器本体2の口部21内に押し込んで係合凸部23、321同士を互いに係合状態に組み付け、次いで、その中栓部材3に対し、塗布部材5が仮保持されたキャップ6をそのまま上から被せてネジ部22に対しねじ込んで閉キャップ状態にする。これだけで製品として出荷可能な最終状態にすることができる。   In the case of the present embodiment, the component (component) is the container main body 2, the inner plug member 3, the valve body 4 with the spring, the application member 5, and the cap 6, but as shown in FIG. The brush 51, the three components are delivered to the drug manufacturer, and the drug manufacturer assembles the other two components to the container body 2 after filling the coating liquid. As well as reliable protection of 51,..., A significant reduction in assembly man-hours is realized. That is, in the container manufacturer, the spring-loaded valve body 4 is assembled to the inner plug member 3 (see FIG. 8) and the application member 5 is integrally assembled to the cap 6 in advance. The inner plug member 3 having the body 4 built therein and the cap 6 on which the application member 5 is temporarily held are provided at three points and delivered to the chemical manufacturer in this state. In the chemical manufacturer, after filling the container body 2 with the coating liquid, first, the inner plug member 3 with the spring-loaded valve body 4 is pushed into the mouth portion 21 of the container body 2 so that the engagement convex portions 23 and 321 are connected to each other. Next, the cap 6 on which the coating member 5 is temporarily held is put on the inner plug member 3 as it is from above and screwed into the screw portion 22 to make a closed cap state. With this alone, a final state that can be shipped as a product can be achieved.

以上の場合、バネ付き弁体4が内装された中栓部材3はその開口311が弁体部41によって閉状態に維持されているため、このような中栓部材3を容器本体2に対し組み付けることで、閉キャップ工程を経る前の段階で塗布液充填後の容器本体2を完全に密封することができるようになる。このため、製品までの組み付けラインにおいて、容器本体2同士の衝突に伴う衝撃が作用したり万一の倒れ等が発生したりしたとしても、容器本体2に充填した塗布液がこぼれたり流出したりする事態の発生を完全に回避することができるようになる。その上に、塗布部材5がキャップ6内に仮保持されて刷毛51,51,…がキャップ6によって完全に遮蔽されて保護された状態になるため、塗布部材5を内装したキャップ6をパーツフィーダにより整列させたとしても、刷毛51,51,…が損傷するおそれはなく、製品としての品質を確実に維持させることができるようになる。しかも、塗布部材5がキャップ6内に仮保持された状態のままのキャップ6を容器本体2の口部21にねじ込むだけで、そのねじ込み操作に案内されて、つまり位置合わせをする必要なく、塗布部材5の外周筒部53と内周筒部54との間に中栓部材の上側係合筒部34が確実に入り込み、次いで係合凸部341,531同士が互いに係合することになる。これにより、キャップ6の閉キャップ工程によって、塗布部材5の中栓部材3に対する組み付けも同時に完了させることができるようになる。このように、薬品メーカでの塗布液充填後の組み付け工程に要する工数を大幅に削減し得る上に、歩留まり発生を可及的に削減又は消滅させることができ、さらに製品として高品質なものに維持させることができるようになる。   In the above case, since the opening 311 of the inner plug member 3 in which the valve body 4 with the spring is housed is maintained closed by the valve body portion 41, the inner plug member 3 is assembled to the container body 2. As a result, the container body 2 after being filled with the coating liquid can be completely sealed before the closed cap step. For this reason, in the assembly line up to the product, the coating liquid filled in the container body 2 may spill or flow out even if an impact due to the collision between the container bodies 2 acts or an accidental collapse occurs. It is possible to completely avoid the occurrence of the situation. Furthermore, since the application member 5 is temporarily held in the cap 6 and the brushes 51, 51,... Are completely shielded and protected by the cap 6, the cap 6 with the application member 5 installed therein is attached to the parts feeder. Even if they are aligned, the brushes 51, 51, ... are not likely to be damaged, and the quality of the product can be reliably maintained. In addition, the cap 6 with the coating member 5 temporarily held in the cap 6 is simply screwed into the mouth 21 of the container body 2 and guided by the screwing operation, that is, it is not necessary to align the coating. The upper engaging cylinder portion 34 of the inner plug member surely enters between the outer peripheral cylindrical portion 53 and the inner peripheral cylindrical portion 54 of the member 5, and then the engaging convex portions 341 and 531 are engaged with each other. Thereby, the assembly | attachment with respect to the inner stopper member 3 of the application member 5 can also be completed simultaneously by the cap closing process of the cap 6. FIG. In this way, the number of man-hours required for the assembly process after filling the coating solution at the chemical manufacturer can be greatly reduced, and the yield can be reduced or eliminated as much as possible, and the product can be of high quality. Can be maintained.

次に、本実施形態の塗布容器を用いて使用者が被塗布面に対し塗布操作をする際の作動状況について説明すると、まず、正立状態の塗布容器からキャップ6を開操作して除去し、塗布部材5の刷毛51,51,…を露出した状態にする。この状態では上記の如く中栓部材3の開口311は閉状態に維持されている。次に、キャップ6を取り去った塗布容器を上下逆にして倒立状態にし、下向きに延びる状態になった刷毛51,51,…(図9参照の一点鎖線参照)を被塗布面Kに押し当てる。これにより、刷毛51,51,…には被塗布面Kから反力が作用し、この反力が刷毛51,51,…を介して可動片55に対し伝達され、伝達された反力(圧力)によって支持片部522,522が湾曲して可動片55は弁体部41の側に平行移動により変位し(図10も併せて参照)、弁体部41の頂部を開弁側(図9,図10の上側)に押すことになる。このように可動片55の伝達位置への変位により、弁体部41は弁バネ部42の閉弁側への付勢力に抗して図9又は図10の上側に押し上げられ、弁部411が弁座312から離れて両者間に上下方向の隙間が生じる、つまり開口311が開切換されることになる。   Next, the operation state when the user performs the coating operation on the surface to be coated using the coating container of this embodiment will be described. First, the cap 6 is opened and removed from the coating container in an upright state. The brushes 51, 51,... Of the application member 5 are exposed. In this state, as described above, the opening 311 of the inner plug member 3 is kept closed. Next, the application container from which the cap 6 has been removed is turned upside down and turned upside down, and the brushes 51, 51,... (See the alternate long and short dash lines in FIG. 9) that extend downward are pressed against the application surface K. As a result, a reaction force acts on the brushes 51, 51,... From the coated surface K, and this reaction force is transmitted to the movable piece 55 via the brushes 51, 51,. ) Causes the support piece portions 522 and 522 to bend and the movable piece 55 to be displaced to the valve body 41 side by parallel movement (see also FIG. 10), and the top of the valve body 41 is opened (see FIG. 9). , On the upper side of FIG. Thus, by the displacement of the movable piece 55 to the transmission position, the valve body 41 is pushed upward in FIG. 9 or 10 against the urging force of the valve spring 42 to the valve closing side, and the valve 411 is moved. A gap in the vertical direction is generated apart from the valve seat 312, that is, the opening 311 is switched to open.

このため、容器本体2内の塗布液は、容器本体2内から弁部411と弁座312との間の環状隙間、開口311と頭部412との間の隙間、及び、透孔551を通して刷毛51,51,…の根本に供給され(図9又は図10の点線の矢印参照)、この塗布液が各刷毛51に沿って先端まで伝わって被塗布面Kに塗布されることになる。塗布操作が終了して刷毛51,51,…を被塗布面Kから離すと、反力が消滅するため、弁体部41は弁バネ部42からの復元側へのバネ付勢力を受けて閉弁状態に復元し、この弁体部41に押し戻されると共に支持片部522,522の弾性復元力を受けて可動片55も元の非伝達位置まで復元することになる。   Therefore, the coating liquid in the container body 2 is brushed from the container body 2 through the annular gap between the valve portion 411 and the valve seat 312, the gap between the opening 311 and the head 412, and the through hole 551. Are supplied to the root of 51, 51,... (See dotted arrows in FIG. 9 or FIG. 10), and the coating liquid is transmitted along the brushes 51 to the tip and applied to the coated surface K. When the application operation is completed and the brushes 51, 51,... Are moved away from the application surface K, the reaction force disappears, so that the valve element 41 is closed by receiving a spring biasing force from the valve spring 42 toward the restoring side. The valve is restored to the valve state and is pushed back by the valve body 41 and receives the elastic restoring force of the support pieces 522 and 522, so that the movable piece 55 is also restored to the original non-transmission position.

以上のように、塗布部材5においては、刷毛51,51,…を有する可動片55が、全周の貫通溝521によって上面壁52から分断されかつ蛇腹状の支持片部522,522によって平行移動により変位可能に形成されているため、被塗布面Kに対する塗布操作を行うために刷毛51,51,…を被塗布面Kに押し当てれば、その反力によって容易にしかも確実に可動片55を変位させることができ、この変位の結果、開口311を開いて容器本体2から塗布液を刷毛51,51,…に対し安定的かつ確実に供給させることができるようになる。   As described above, in the application member 5, the movable piece 55 having the brushes 51, 51,... Is separated from the upper surface wall 52 by the entire circumferential through groove 521 and is translated by the bellows-like support piece portions 522 and 522. , When the brushes 51, 51,... Are pressed against the surface to be coated K in order to perform the coating operation on the surface to be coated K, the movable piece 55 can be easily and reliably moved by the reaction force. As a result of this displacement, the opening 311 is opened, and the coating liquid can be stably and reliably supplied from the container body 2 to the brushes 51, 51,.

<他の実施形態>
なお、本発明は上記実施形態に限定されるものではなく、その他種々の実施形態を包含するものである。すなわち、上記実施形態では、可動片55として平面視で略円形にしたものを示したが、これに限らず、例えば四角形等の多角形や楕円形等の他の形状にしてもよい。
<Other embodiments>
In addition, this invention is not limited to the said embodiment, Various other embodiments are included. That is, in the above-described embodiment, the movable piece 55 is substantially circular in plan view. However, the shape is not limited thereto, and other shapes such as a polygon such as a quadrangle and an ellipse may be used.

又、支持片部522,522として、可動片55の直径方向両端部に計2つ設けた場合を示したが、これに限らず、周方向に互いに間隔を開けて3箇所又は4箇所以上に設けてもよく、さらには全周に亘り無端状の支持片部を形成するようにしてもよい。例えば図11に示すように、支持片部522と同様断面形状を有する支持片部523を貫通溝521を全周に亘り跨ぐように形成し、かかる支持片部523によって可動片55の全周を支持するようにしてもよい。この場合には、弁体部41の開弁時における塗布液の供給を透孔521のみに制限することができ、塗布液の性状(例えば粘度)によって好ましい滲出状況とすることができる。   Moreover, although the case where a total of two support piece portions 522 and 522 are provided at both ends in the diameter direction of the movable piece 55 is shown, it is not limited to this, and there are three or four or more places spaced apart from each other in the circumferential direction. It may be provided, and furthermore, an endless support piece may be formed over the entire circumference. For example, as shown in FIG. 11, a support piece portion 523 having a cross-sectional shape similar to that of the support piece portion 522 is formed so as to straddle the entire circumference of the through groove 521, and the entire circumference of the movable piece 55 is formed by the support piece portion 523. You may make it support. In this case, the supply of the coating liquid when the valve body 41 is opened can be limited only to the through-hole 521, and a preferable leaching situation can be obtained depending on the properties (for example, viscosity) of the coating liquid.

さらに、上記実施形態では、キャップ6に対し塗布部材5を一体的に組み付けて仮保持可能としているが、これに限らず、塗布部材5のみならず、バネ付き弁体4を内装させた中栓部材3を含め、全ての構成要素をキャップ6内に一体的に組み付けて仮保持可能にするようにしてもよい。この場合には、例えば図12に示すように、キャップ6の内周面に対し実施形態における保持凸部63と同様形状を有しその形成位置をさらに下側の下端開口側に位置変更した保持凸部64を形成する一方、実施形態における塗布部材5の係止突起532を省略し、その代わりに中栓部材3の下側係合筒部32の下端縁から外周側に突出するように係止突起322を形成するようにすればよい。この係止突起322,322も、実施形態の係止突起532と同様に周方向に少なくとも3つ以上で同様の形状を有するように形成すればよい。   Furthermore, in the said embodiment, although the application | coating member 5 is assembled | attached integrally with the cap 6 and can be temporarily hold | maintained, it is not restricted to this, The inside plug which built not only the application | coating member 5 but the valve body 4 with a spring. All the components including the member 3 may be integrally assembled in the cap 6 so as to be temporarily held. In this case, for example, as shown in FIG. 12, the holding has the same shape as the holding convex portion 63 in the embodiment on the inner peripheral surface of the cap 6 and the position of the forming is further changed to the lower end opening side on the lower side. While forming the convex part 64, the latching protrusion 532 of the application | coating member 5 in embodiment is abbreviate | omitted, and it engages so that it may protrude on the outer peripheral side from the lower end edge of the lower side engagement cylinder part 32 of the inner plug member 3 instead. A stop protrusion 322 may be formed. The locking protrusions 322 and 322 may be formed so as to have the same shape with at least three or more in the circumferential direction similarly to the locking protrusion 532 of the embodiment.

このようにすることで、容器メーカにおいて、予め塗布部材5と、バネ付き弁体4を内装した中栓部材3とを一体的に組み付け、この組み付けた状態のものをキャップ6に対し内嵌させて仮保持させた上で、この塗布部材5とバネ付き弁体4を内装した中栓部材3とが一体的に仮保持されたキャップ6と、容器本体2との2つの構成要素を薬品メーカに対し納入することができる。そして、薬品メーカでは容器本体2に対し塗布液を充填した後に、図13にも示すように上記の一体的に保持された状態のキャップ6を塗布液充填済みの容器本体2に対し閉操作するという閉キャッピング工程を行うだけで、最終製品を完成させることができるようになる。これにより、実施形態の場合における中栓部材3の容器本体2に対する組み付け工程を削減することができ、実施形態の場合よりも組み付け工数の削減を図ることができる上に、容器メーカから薬品メーカに搬送する構成要素の数も削減させることができるようになる。   By doing in this way, in the container manufacturer, the application member 5 and the inner plug member 3 with the spring-loaded valve body 4 built therein are assembled together, and the assembled state is fitted into the cap 6. The two components of the cap body 6 and the container body 2 which are temporarily held integrally with the coating member 5 and the inner plug member 3 in which the valve body 4 with the spring is housed are integrated into the chemical manufacturer. Can be delivered to. Then, after filling the container body 2 with the coating liquid, the chemical manufacturer closes the cap 6 in the state of being integrally held as shown in FIG. 13 with respect to the container body 2 filled with the coating liquid. The final product can be completed simply by performing the closed capping process. As a result, the assembly process of the inner plug member 3 to the container body 2 in the case of the embodiment can be reduced, and the number of assembling steps can be reduced as compared with the case of the embodiment. The number of components to be conveyed can be reduced.

なお、以上の係止突起322,532は周方向の一部から点状に突出するものの他に、例えば薄肉のものを周方向に所定長さに亘って突出させた係止突片の如き形状や、あるいは全周に亘って突出させた係止突縁の如き形状等の凸状係止部を採用することもできる。   The above-mentioned locking projections 322 and 532 have a shape like a locking protrusion, for example, a thin-walled one protruding over a predetermined length in the circumferential direction in addition to one protruding in a dotted shape from a part in the circumferential direction. Alternatively, it is also possible to employ a convex locking portion such as a shape such as a locking protrusion that protrudes over the entire circumference.
