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

  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.

  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.

  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).

Japanese Patent Laid-Open No. 11-138086 JP 2000-72171 A JP-A-11-319661

  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.

  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.

  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.

  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.

  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).

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an application container according to an embodiment of the present invention, FIG. 2 shows a partially enlarged view thereof, and FIG. 3 shows an exploded perspective view thereof. In each of these drawings, reference numeral 2 denotes a container main body in which the coating liquid is accommodated, 3 denotes an inner plug member that covers the mouth portion 21 of the container main body 2, and 4 denotes an inner plug for opening and closing the opening of the inner plug member 3 A spring-equipped valve body housed in the member 3, an application member 5 provided with a plurality of brushes 51, 51,... Attached so as to cover the inner plug member 3, and a container body 6 covering the inner plug member 3 and the application member 2 is a cap to be attached to 2. All the constituent elements 2 to 6 of the application container are made of synthetic resin. Hereinafter, the vertical relationship in the state illustrated in FIGS. 1 to 3 will be described using the terms “upper” or “lower”.

  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.

  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.

  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,...

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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,.

<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.

  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.

  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.

  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.

  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.
