A coating container is known that is formed with a valve seat that comes into contact with the valve seat.

Japanese Patent Application Publication No. 2018-34859

However, in the conventional coating container described above, communication between the communication hole and the discharge hole is blocked by the valve body and the valve seat when not in use, so in order to impregnate the coating member with the liquid, an overcap is required. After removing it, it is necessary to push the application member to open the valve. For this reason, it is difficult to impregnate the application member with the content liquid additionally before use. Further, if the communication hole and the discharge hole are in constant communication, there is a risk that the liquid content may leak from the discharge hole during use.

The present invention has been made in consideration of the above circumstances, and provides a coating container that is capable of impregnating the coating member with the liquid content before use while suppressing leakage of the liquid content during use. The purpose is to

The coating container of the present invention is attached to the mouth of a container body, and has upper and lower portions formed with a communication hole that communicates with the inside of the container body, and a discharge hole that communicates with the communication hole and discharges the liquid content of the container body. a cylindrical inner plug member extending in the direction; a bottomed cylindrical accommodating portion supported movably in the vertical direction inside the inner plug member; a holder having a stopper that is closably opened from below and forming a communication path between the inner stopper member and the inner stopper member, which communicates the inside of the accommodating part and the inside of the container body; an application member protruding upward from the holder; a biasing member for biasing the holder upward against the inner plug member; An overcap that closes the discharge hole.

According to the present invention, when the overcap is attached to the mouth of the container body, the plug body opens the communication hole of the inner plug member, so that the inside of the accommodating part and the inside of the container body communicate through the communication path. ing. Therefore, by inverting or shaking the coating container with the overcap attached, the liquid inside the container body can be supplied into the storage section. At this time, since the discharge hole of the inner plug member is closed by the overcap, the application member can be impregnated with the content liquid before use while suppressing leakage of the content liquid.
Further, when the overcap is removed from the mouth of the container body, the restriction on the upward movement of the holder is released, so that the stopper rises and closes the communication hole. Thereby, communication between the inside of the storage part and the inside of the container main body is cut off, and leakage of the content liquid during use can be suppressed.
As described above, it is possible to provide a coating container that allows the coating member to be impregnated with the liquid content before use while suppressing leakage of the liquid content during use.

In the above application container, the inner plug member has a protruding tube that surrounds the accommodating section and is formed with the discharge hole, and the holder extends from the accommodating section over the upper end of the protruding tube. It may have an operation part extending toward the outer circumferential side of the cylinder.

According to the present invention, when the overcap is removed from the mouth of the container body and the holder is raised, the holder is lowered by grasping the operation part, etc., thereby opening the communication hole of the inner plug member to the plug body. can be done. Thereby, the inside of the storage part and the inside of the container main body are communicated through the communication path, and the content liquid in the container main body can be supplied into the storage part by shaking the coating container or the like. Therefore, with the overcap removed, it is possible to replenish the contents of the application member without touching the application member, and by pressing the application member against the part to be coated and pushing the application member in, the communication hole is opened. A coating container that does not require an opening operation can be obtained. Moreover, when the content liquid becomes insufficient, the effort of reattaching the overcap can be reduced.

According to the present invention, it is possible to provide a coating container that allows the coating member to be impregnated with the liquid content before use while suppressing leakage of the liquid content during use.

The upper part of the peripheral wall 31a is in close sliding contact with the inner circumferential surface of the protruding cylinder 27 of the discharge cylinder part 26, and is arranged to be movable up and down with respect to the protruding cylinder 27. The upper end portion of the peripheral wall 31a is capable of protruding higher than the protruding tube 27. A fitting rib 32 that protrudes radially inward and extends in the vertical direction is formed on the inner circumferential surface of the peripheral wall 31a. A plurality of fitting ribs 32 are formed at intervals in the circumferential direction. The bottom wall 31b is formed so that its outer diameter is larger than the inner diameter at the upper part of the hanging tube 28. A pedestal protrusion 33 that protrudes upward is formed on the upper surface of the bottom wall 31b. A plurality of pedestal protrusions 33 are formed at intervals in the circumferential direction on the outer periphery of the upper surface of the bottom wall 31b.

A communication hole 34 is formed in the housing portion 31 . The communication hole 34 is formed across the peripheral wall 31a and the bottom wall 31b. A plurality of communication holes 34 are formed at intervals in the circumferential direction. Thereby, the inside of the accommodating part 31 communicates with the outside of the accommodating part 31 through the communication hole 34. However, the location where the communication hole 34 is formed is not limited to the above-mentioned location. For example, it may be formed to vertically penetrate the bottom wall 31b, or it may be formed to penetrate the peripheral wall 31a in the radial direction.

The plug body 35 extends from the inside of the discharge tube 26 through the communication hole 21 to below the discharge tube 26 . The plug body 35 includes a shaft portion 36 extending downward from the bottom wall 31b of the accommodating portion 31, and a plug body 37 supported by the lower end portion of the shaft portion 36. The shaft portion 36 extends in the vertical direction centering on the container axis O. The entire portion of the shaft portion 36 that faces the discharge cylinder portion 26 in the radial direction is formed so as to be spaced from the inner peripheral surface of the discharge cylinder portion 26 in the radial direction. A lower end portion of the shaft portion 36 is located inside the hanging tube 28. However, the lower end portion of the shaft portion 36 may protrude downward from the communication hole 21 of the hanging tube 28. A vertical rib 38 is formed on the outer circumferential surface of the shaft portion 36 and projects outward in the radial direction and extends in the vertical direction. A plurality of vertical ribs 38 are formed at intervals in the circumferential direction. The vertical ribs 38 are connected to the lower surface of the bottom wall 31b of the accommodating portion 31 at their upper ends, and extend at intervals in the radial direction with respect to the inner circumferential surface of the discharge cylinder portion 26.

Then, the plug body 37 rises relative to the discharge cylinder 26 and the first sealing surface 37b comes into close contact with the inner circumferential surface or lower end surface (lower edge) of the communication hole 21, so that the plug body 37 closes the communication hole 21. It is closed from below, and communication between the inside of the accommodating part 31 and the inside of the container body 2 through the communication path 40 is cut off.

The application member 50 is formed in a cylindrical shape coaxial with the container axis O. The application member 50 is disposed within the accommodating portion 31 so as to protrude above the accommodating portion 31 . The application member 50 is placed on the base protrusion 33. The application member 50 projects upward from the discharge hole 22 . In the illustrated example, the upper end portion of the application member 50 is processed so that the cut surfaces 51 face each other in the radial direction, so that the upper end portion has a shape in which a ridgeline portion is disposed at the top. However, the shape of the upper end portion of the coating member 50 is not limited to the illustrated example, and may be changed as appropriate depending on the portion to be coated. The application member 50 is made of an impregnating material that can be impregnated with the content liquid. Examples of the impregnating material include porous materials such as sponges, and fibrous bodies in which synthetic fibers are solidified with a resin solution and can be impregnated with a liquid content using capillary action.

The biasing member 60 is a coil spring centered on the container axis O. The biasing member 60 is arranged in a compressed state between the hanging tube 28 of the inner plug member 20 and the holder 30.

It includes an extending annular step portion 72, a lower tube portion 73 extending downward from the outer peripheral edge of the step portion 72, and a threaded tube portion 74 extending downward from the lower end of the lower tube portion 73. The threaded tube portion 74 is arranged to surround the mouth portion 10 of the container body 2. The threaded cylindrical portion 74 has a female thread on its inner peripheral surface and is threaded onto the mouth portion 10 . The lower cylinder part 73 is arranged so as to mainly surround the protruding cylinder 27 of the discharge cylinder part 26. The lower cylindrical portion 73 is formed to have an inner diameter smaller than the inner diameter of the threaded cylindrical portion 74 . The lower end surface of the lower cylinder part 73 is in contact with the flange part 25 of the mounting cylinder part 23 of the inner plug member 20 from above the flange part 25 . The upper cylinder part 71 is arranged so as to surround a portion of the application member 50 that protrudes upward from the discharge cylinder part 26 . A second annular sealing surface 71 a is formed on the lower end surface of the upper cylinder part 71 and extends downward and radially outward from the lower end edge of the inner circumferential surface of the upper cylinder part 71 . The second sealing surface 71a is in close contact with the upper end edge of the discharge cylinder portion 26 over the entire circumference. Thereby, the upper cylinder part 71 and the top wall part 70 close the discharge hole 22.

A regulating rib 75 is formed on the inner circumferential surface of the upper cylinder portion 71 so as to protrude inward in the radial direction and extend in the vertical direction. A plurality of regulating ribs 75 are formed at intervals in the circumferential direction. The regulating rib 75 is formed so as to be spaced apart from the application member 50. The lower end edge of the regulating rib 75 is spaced apart from the discharge cylinder portion 26 . A portion of the lower end edge of the regulating rib 75 protrudes downward and contacts the upper end edge of the accommodating portion 31 of the holder 30 from above the accommodating portion 31 . Thereby, the overcap 4 restricts the upward movement of the holder 30 which is urged upward by the urging member 60 .

Next, the operation of the coating container 1 described above will be explained.
When the overcap 4 is attached to the mouth 10 of the container body 2, the plug 35 of the holder 30 opens the communication hole 21 of the inner plug member 20, so that the inside of the container 31 and the container are connected through the communication path 40. It communicates with the inside of the main body 2. Therefore, by inverting or shaking the coating container 1 with the overcap 4 attached, the liquid inside the container body 2 can be supplied into the storage section 31. Since the discharge hole 22 of the inner plug member 20 is closed by the upper cylinder portion 71 of the overcap 4, it is possible to impregnate the application member 50 with the liquid content before use while suppressing leakage of the liquid content.
Further, when the overcap 4 is removed from the mouth 10 of the container body 2, the restriction on the rise of the holder 30 by the restriction rib 75 is released, so the stopper 35 rises and closes the communication hole 21. Thereby, communication between the inside of the accommodating part 31 and the inside of the container main body 2 is cut off, and leakage of the liquid content during use can be suppressed.
As described above, it is possible to provide the coating container 1 that allows the coating member 50 to be impregnated with the liquid content before use while suppressing leakage of the liquid content during use.

Further, the discharge hole 22 is closed when the overcap 4 is attached, and when the overcap 4 is removed, the discharge hole 22 is opened and the communication hole 21 is closed after the holder 30 starts to rise. Therefore, when the overcap 4 is removed, the application container 1 can be put into a usable state with the internal pressure of the container body 2 once released. Therefore, leakage of the content liquid during use due to an increase in the internal pressure of the container body 2 can be suppressed.

[Second embodiment]
Next, a second embodiment of the coating container according to the present invention will be described with reference to the drawings. The second embodiment differs from the first embodiment in that the holder 30 includes an operating section 42.

The lower end surface 71Aa of the upper cylinder portion 71A is in close contact with the upper surface of the collar portion 43 over the entire circumference. In addition to the urging force of the urging member 60, the fastening force of the overcap 4 acts between the upper cylinder portion 71A and the collar portion 43. Thereby, the overcap 4 seals between the lower end surface 71Aa of the upper cylinder portion 71A and the upper surface of the collar portion 43, thereby closing the discharge hole 22 and restricting the upward movement of the holder 30.

Next, the operation of the coating container 1A described above will be explained.
As shown in FIG. 4, when the overcap 4 is removed from the mouth 10 of the container body 2, the restriction on the rise of the holder 30 is released, so the stopper 35 rises and opens the communication hole 21 of the inner stopper member 20. Obstruction. From this state, by lowering the holder 30 by grasping the operating portion 42, etc., the communication hole 21 can be opened in the plug body 35. As a result, the inside of the storage section 31 and the inside of the container body 2 are communicated through the communication path 40, and the content liquid in the container body 2 can be supplied into the storage section 31 by shaking the application container 1A or the like. Can be done. Therefore, with the overcap 4 removed, it is possible to replenish the content liquid to the application member 50 without touching the application member 50. Therefore, when the content liquid is insufficient, the effort of reattaching the overcap 4 can be reduced. Further, by pressing the coating member 50 against the part to be coated and pushing the coating member 50 in, the coating container 1A can be provided without requiring an operation of opening the communication hole 21.

Contact from below 81. In this state, when the lower part 46 of the operating part 42 of the holder 30 is displaced radially inward so as to sandwich the protruding tube 27B, the opposing inclined surface 48 comes into sliding contact with the inclined surface 81, and the lower part of the operating part 42 of the holder 30 46 is displaced downward and radially inward. As a result, the entire holder 30 is lowered relative to the inner plug member 20, as shown by the imaginary line in the figure, so that the communication hole 21 of the inner plug member 20 can be opened to the plug body 35. Therefore, the same effects as in the second embodiment described above can be achieved.

Note that the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications can be made within the technical scope thereof.
For example, in the above embodiment, the overcap 4 directly contacts the holder 30 to restrict the rise of the holder 30, but the present invention is not limited to this, and the overcap contacts the application member and presses the application member downward. The rise of the holder may be restricted by doing so.

Further, in the above embodiment, the applicator 50 protrudes upward from the discharge hole 22 when the overcap 4 is attached to the mouth 10 of the container body 2, but at least when the overcap is removed, the applicator 50 protrudes upward from the discharge hole 22.
