[Problems to be solved by the invention]

However, in the above-mentioned previous coating container, since the valve is closed in the standby state, if, for example, the temperature of the hand is transmitted to the container body, the pressure inside the container body will increase. In this state, if the impregnating material is pressed toward the inside of the container body and the valve is opened, there is a possibility that the pressure of the container body is released, the content liquid force is strongly ejected, and the content liquid is excessively applied to the coated portion.

The present invention has been completed in view of such circumstances, and its object is to provide a coating container that can apply an appropriate amount of content liquid to a portion to be coated and has excellent usability. [Means to solve the problem]

(1) As the first aspect of the present invention, a coating container is provided, which includes: a container body that contains a content liquid; a cylindrical intermediate plug member that is attached to the mouth of the container body; and an impregnated material, which It is embedded inside the middle plug member and can be impregnated with the content liquid; the middle plug member includes: an impregnating material accommodating portion that accommodates the impregnating material in a state where the front end portion protrudes; and a valve body accommodating portion that is different from the above The impregnated material accommodating portion communicates, and has a valve seat on the impregnated material accommodating portion side, and a valve body support portion on the container body side, the valve body is movably arranged between the valve seat and the valve body support portion; and The center plug member is formed with a communication groove that forms a gap between the valve body and the valve body accommodating portion when the valve body is supported by the valve body supporting portion. The impregnated material accommodating portion communicates the container body with the outside.

According to the first aspect of the present invention, in the upright state where the container body is on the lower side and the impregnating material is on the upper side, the valve body is supported on the valve body support portion due to the formation between the valve body and the valve body receiving portion The communication groove of the gap allows the container body to communicate with the outside, so the pressure of the container body is released. Therefore, when the coating container is used, the discharge of the content liquid caused by the pressure difference between the inside and the outside of the container body does not occur. In addition, when the coating container is used from the upright state to the upside down state, the valve body is moved up and down to squeeze a fixed amount of the content liquid in the valve body storage portion to the impregnated material storage portion. Then, when the valve body contacts the valve seat, the supply of the content liquid from the valve body housing portion to the impregnating material is restricted, so that the impregnating material can be impregnated excessively to prevent dripping.

(2) As a second aspect of the present invention, in the first aspect, the valve seat may be formed in the state of being in contact with the valve body to supply the content liquid from the valve body housing portion to the impregnating material The content of the liquid supply tank.

According to the second aspect of the present invention, even when the container body is brought upside down and the valve body is in contact with the valve seat, the content liquid can be supplied from the valve body housing portion to the impregnating material. Therefore, even if the content liquid is difficult to flow out during use of the coating container, the number of operations such as impregnating the content liquid with the impregnating material again by temporarily changing the coating container to the upright state and then to the inverted state can be reduced.

(3) As a third aspect of the present invention, in the first aspect or the second aspect, the valve body housing portion has a peripheral wall connecting the valve seat and the valve body support portion; the valve body shape It is aspheric and has a guide surface guided by the peripheral wall of the valve body accommodating portion, and the communication groove is formed on the guide surface of the valve body.

According to the third aspect of the present invention, when the container body is in the upright state, the container body communicates with the outside through the communication groove formed in the valve body, so the pressure of the container body is released. Therefore, when the coating container is used, the discharge of the content liquid caused by the pressure difference between the inside and the outside of the container body does not occur. In addition, the valve body is aspherical and has a guide surface that is guided by the peripheral wall of the valve body receiving portion. Therefore, even if the valve body moves up and down, the posture of the valve body is maintained in a fixed posture, and the pressure of the container body can be surely released through the communication groove formed in the valve body. [Effect of invention]

According to the present invention, it is possible to obtain a coating container capable of applying an appropriate amount of content liquid to a portion to be coated and having excellent usability.

The coating container according to the embodiment of the present invention will be described below with reference to the drawings.

(First embodiment) As shown in FIG. 1, the coating container 1 of the present embodiment includes a bottomed cylindrical container body 2 for containing the content liquid to be coated on the coated portion, and a cylindrical body mounted inside the mouth portion 10 of the container body 2 The coating plug 3 and the top cover 4 in the shape of a cylinder that is detachably attached to the mouth portion 10 of the container body 2 and covers the coating plug 3. In addition, the content liquid is not particularly limited, and examples thereof include liquids such as hair growth agents, beriberi, and other medicines applied to the body to be coated, such as beriberi, and cosmetics.

In FIG. 1, the central axes of the container body 2, the coating plug 3 and the top cover 4 are arranged on a common axis. In this embodiment, the common axis is referred to as the container axis O, the side of the top cover 4 along the direction of the container axis O is referred to as upward, and the opposite side (the container body 2 side) is referred to as downward. Furthermore, the direction of the container axis O can also be referred to as an up-down direction, and the direction of the container axis O direction from the following bottom of the container body 2 to the following lid top wall 61 of the top cover 4 is referred to as upward, and the opposite direction is referred to as Below. That is, the direction from the bottom of the container body 2 toward the following upper end portion 30a (front end portion) of the impregnating material 30 may be referred to as upward, and the opposite direction may be referred to as downward. In addition, the direction crossing the container axis O in a plan view from the container axis O is called a radial direction, and the direction around the container axis O is called a circumferential direction.

The mouth portion 10 of the container body 2 is formed to have a smaller diameter than the portions (shoulder portion, body portion, and bottom portion) other than the mouth portion 10 in the container body 2. In the example shown in the figure, a male thread capable of screwing the top cover 4 is formed on the outer peripheral surface of the mouth portion 10 of the container body 2. The top cover 4 is formed into a topped cylindrical shape having a cover cylinder 60 that surrounds the mouth portion 10 of the container body 2 and the coating plug 3 from the outside in the radial direction, and a cover ceiling that closes the opening at the upper end of the cover cylinder 60壁61。 Wall 61.

In the cap cylinder 60, a female thread that is screwed to the male thread of the mouth portion 10 of the container body 2 is formed on the inner peripheral surface of the portion surrounding the mouth portion 10 of the container body 2. As a result, the top cover 4 is detachably attached to the mouth 10 of the container body 2. Furthermore, the installation method of the top cover 4 is not limited to screwing, and the top cover 4 may be installed by, for example, undercutting and fitting the mouth 10 of the container body 2.

A support cylindrical portion 63 is formed on the lid top wall 61 and extends downward, and is detachably fitted to the outer peripheral surface of the second cylindrical portion 43 of the coating plug 3 described below. Thereby, the top cover 4 can be rotated around the container axis O in a state where the support tube portion 63 is fitted to the second tube portion 43, so that the top cover 4 can be stably carried out on the mouth portion 10 of the container body 2 Installation and disassembly operations.

The coating plug 3 includes a cylindrical middle plug member 20 attached to the mouth portion 10 of the container body 2 and an impregnating material 30 attached to the inner side of the middle plug member 20 and capable of impregnating the content liquid. Examples of the impregnating material 30 include porous materials such as sponges and fibrous bodies. Synthetic fibers of the fibrous body can be cured with a resin solution and impregnated with the content liquid by capillary phenomenon. However, the impregnating material 30 is not limited to such cases, and the content liquid may be impregnated.

In the case where the above-mentioned fiber body is used as the impregnating material 30, a plurality of synthetic fibers (for example, polyester fibers, nylon fibers, acrylic fibers, etc.) having a fiber diameter of, for example, several μ to tens of μ are bundled into a bundle Use resin solution to solidify the bundle of synthetic fibers. At this time, the density of the synthetic fiber may be adjusted so that the porosity (the volume ratio or volume ratio of the synthetic fiber in the solid part and the pores (voids)) is in the range of, for example, 40% to 80%. With this, the content liquid can be appropriately impregnated using the capillary phenomenon. In addition, as said resin solution, what melt|dissolved the polyurethane resin solution, for example can be used.

The impregnation material 30 is formed in a substantially cylindrical shape arranged coaxially with the container axis O. The upper end portion 30a (front end portion) of the impregnated material 30 protrudes upward from the center plug member 20. The upper end portion 30a of the impregnating material 30 is formed in a semi-ellipsoid shape. In addition, the shape of the upper end portion 30a of the impregnating material 30 is not limited to this shape, and can be appropriately changed according to the portion to be coated. On the other hand, the lower end 30 b of the impregnating material 30 is arranged inside the center plug member 20. The lower end 30b of the impregnated material 30 gradually decreases in diameter as it faces downward.

The center plug member 20 has an annular flange portion 40, a cylindrical fitting cylindrical portion 41, a top cylindrical first cylindrical portion 42, and a bottomed cylindrical second cylindrical portion 43. The flange portion 40, the fitting cylindrical portion 41, the first cylindrical portion 42, and the second cylindrical portion 43 are arranged coaxially with the container axis O as a common axis. The flange portion 40 is disposed on the upper end opening edge of the mouth portion 10 of the container body 2 and extends radially inward from the upper end opening edge. The fitting cylindrical portion 41 extends downward from the flange portion 40, and its outer peripheral surface is fitted to the inner peripheral surface of the mouth portion 10.

The first cylindrical portion 42 is arranged radially inward of the fitting cylindrical portion 41 and extends downward from the flange portion 40. The second cylindrical portion 43 is arranged radially inward of the fitting cylindrical portion 41 and extends upward from the flange portion 40. The bottom of the second cylindrical portion 43 is formed integrally with the top of the first cylindrical portion 42, and the outer diameter of the second cylindrical portion 43 is smaller than the inner diameter of the fitting cylindrical portion 41 and larger than the outer diameter of the first cylindrical portion 42. The first cylindrical portion 42 with a top and the second cylindrical portion 43 with a bottom have a communication hole 23 formed coaxially with the container axis O to communicate with each other.

The second cylindrical portion 43 is formed with an impregnated material accommodating portion 21 that accommodates the impregnated material 30 in a state where the upper end portion 30a protrudes. The impregnated material accommodating portion 21 has a length capable of accommodating the impregnated material 30 with a total height of about 2/3. That is, the impregnating material accommodating portion 21 can accommodate a portion of the impregnating material 30 corresponding to about 2/3 of the total length of the impregnating material 30 in the direction of the container axis O. A plurality of fitting ribs 21a are formed in the impregnated material accommodating portion 21. A plurality of fitting ribs 21a extend in the axial direction along the inner peripheral surface of the second cylindrical portion 43, and are arranged at intervals in the circumferential direction. The impregnating material 30 is fitted into the impregnating material accommodating portion 21 with a plurality of fitting ribs 21a in a state where the outer circumferential surface is slightly deformed radially inward.

The lower end surface of the impregnated material 30 is supported by a plurality of support ribs 45 protruding from the bottom of the second cylindrical portion 43. A plurality of supporting ribs 45 are formed at the bottom of the second cylindrical portion 43 along the opening edge of the communication hole 23 at intervals in the circumferential direction. The first cylindrical portion 42 forms a valve body accommodating portion 22 having a valve seat 22a on the impregnated material accommodating portion 21 side, a valve body supporting portion 22b on the container body 2 side, and the valve body 22c using its own weight It is movably arranged between the valve seat 22a and the valve body support portion 22b. That is, the valve seat 22a is formed near the impregnated material accommodating portion 21 in the first cylinder portion 42, the valve body support portion 22b is formed near the container body 2 in the first cylinder portion 42, and the valve body accommodating portion 22 is formed in the first cylinder In the portion 42, between the valve seat 22 a and the valve body support portion 22 b, between the valve seat 22 a and the valve body support portion 22 b in the valve body accommodating portion 22, the valve body 22 c is movably arranged by its own weight.

The valve seat 22 a is formed on the top of the first cylindrical portion 42 and is formed on the peripheral edge of the communication hole 23. The valve seat 22a is formed coaxially with the communication hole 23, and is formed in a tapered shape whose diameter decreases upward. The maximum diameter of the valve seat 22a is larger than the outer diameter of the valve body 22c. Also, the minimum diameter of the valve seat 22a is smaller than the outer diameter of the valve body 22c. Therefore, the valve body 22c can be seated across the entire circumference of the valve seat 22a.

The valve body supporting portion 22b prevents the valve body 22c from falling from the bottom opening of the first cylindrical portion 42 (that is, the opening provided in the bottom) toward the container body 2 side. In addition, the valve body supporting portion 22b guides a person who moves up and down the valve body 22c in the valve body accommodating portion 22. The valve body support portion 22b is formed in a rib shape extending downward from the top of the first cylindrical portion 42 in the direction of the container axis O along the inner circumferential surface. A plurality of valve body supporting portions 22b are formed at intervals in the circumferential direction of the inner peripheral surface of the first cylindrical portion 42. The lower end of the valve body support portion 22b protrudes radially inward.

The imaginary circle formed by the radial inner edge of the lower end of the plurality of valve body support portions 22b is smaller than the outer diameter of the valve body 22c. Therefore, the valve body 22c is supported at the lower end of the plurality of valve body support portions 22b. The valve body 22c is a steel ball with a specific gravity greater than that of the content liquid. Furthermore, the valve body 22c may be a resin ball if the specific gravity is greater than the content liquid. In addition, the valve body support portion 22b may be constituted only by the lower end portion thereof. That is, the valve body support portion 22b may not extend from the top of the first cylindrical portion 42 downward in the direction of the container axis O in a rib shape. In this case, the outer diameter of the valve body 22c may be smaller than the inner diameter of the valve body accommodating portion 22. In the above-described configuration, the plug member 20 is formed with a communication groove 50 that allows the container body 2 to pass through the valve body accommodating portion 22 and the impregnating material accommodating portion 21 with the valve body 22 c supported by the valve body supporting portion 22 b. Connect with the outside.

The communication groove 50 has a first communication groove 51, a second communication groove 52, and a third communication groove 53. The first communication groove 51 is formed in the valve body accommodating portion 22 of the first cylindrical portion 42. The first communication groove 51 is formed in the gap between the rib-shaped valve body support portions 22b adjacent in the circumferential direction. That is, a plurality of first communication grooves 51 are formed at intervals in the circumferential direction along the inner circumferential surface of the first cylindrical portion 42, and each extends axially toward the top of the first cylindrical portion 42.

The second communication groove 52 and the third communication groove 53 are formed in the impregnated material accommodating portion 21 of the second cylindrical portion 43. The second communication groove 52 is formed in the gap between the support ribs 45 adjacent in the circumferential direction. That is, the second communication groove 52 is formed at the bottom of the second cylindrical portion 43 at a radial distance from the communication hole 23 at intervals in the circumferential direction. The third communication groove 53 is formed in the gap between the fitting ribs 21a adjacent in the circumferential direction. That is, a plurality of third communication grooves 53 are formed at intervals along the inner circumferential surface of the second cylindrical portion 43 in the circumferential direction, each opening toward the top of the second cylindrical portion 43 (that is, the opening provided at the top) along the axis To extend.

In addition, in the valve seat 22a of the present embodiment, a content liquid supply tank 22a1 is formed, and the content liquid supply tank 22a1 supplies content from the valve body housing portion 22 to the impregnating material 30 in a state where the valve seat 22a is in contact with the valve body 22c liquid. The content liquid supply tank 22a1 is sufficiently smaller than the communication tank 50 described above. The content liquid supply groove 22a1 is formed in a radial shape so that the sealing surface of the valve seat 22a annularly contacting the valve body 22c crosses in the radial direction. Even in a state where the valve body 22c is in contact with the valve seat 22a, the content liquid supply tank 22a1 can supply a small amount of content liquid from the valve body housing portion 22 to the impregnating material 30.

Next, a case where the content liquid is applied to the application portion by the application container 1 configured as described above will be described.

When applying the content liquid, first remove the top cover 4 from the mouth portion 10 of the container body 2. For example, in the case where the container body 2 contains volatile content liquid (beriberi, etc.), the heat of the hand is transferred to the container body 2, and the internal pressure of the container body 2 is likely to rise. However, as shown in FIG. 1, that is, in the upright state where the container body 2 is on the lower side and the impregnating material 30 is on the upper side, the valve body 22 c is supported by the valve body support portion 22 b by being provided in the center bolt member The communication groove 50 of 20 connects the container body 2 to the outside. In addition, the so-called upright state means that the coating container 1 assumes a state in which the container body 2 is positioned below the impregnating material 30 in the vertical direction and the impregnating material 30 is positioned above the container body 2 in the vertical direction, and includes the coating container 1 A state where the front end portion of the impregnated material 30 is directed obliquely upward with respect to the vertical direction.

That is, after the gas pressurized inside the container body 2 enters the valve body accommodating portion 22 from the bottom opening of the first cylindrical portion 42 and passes through the first communication groove 51 in the axial direction through the gap of the valve body supporting portion 22b, The impregnated material accommodating portion 21 enters through the communication hole 23. The gas entering the impregnated material accommodating portion 21 passes through the second communication groove 52 of the gap between the support ribs 45 in the radial direction, and then passes through the third communication groove 53 of the gap between the fitting ribs 21a in the axial direction from the second cylindrical portion 43 The top opening is released to the outside. Therefore, the top cover 4 is removed from the container body 2 and the pressure of the container body 2 is released, and the pressure difference between the inside and outside of the container body 2 disappears.

When the coating container 1 is used, as shown in FIG. 2, it is assumed that the container body 2 is on the upper side and the impregnating material 30 is on the lower side. In addition, the so-called inverted state includes a tilt posture in which the impregnating material 30 is directed obliquely downward. To explain in more detail, the so-called upside-down state means that the coating container 1 assumes a state in which the container body 2 is positioned vertically above the impregnating material 30 and the impregnating material 30 is positioned vertically below the container body 2, and includes coating. The container 1 assumes a state in which the front end of the impregnating material 30 faces the obliquely downward direction with respect to the vertical direction. In this inverted state, the valve body 22c is separated from the lower end of the valve body support portion 22b by its own weight, and moves toward the valve seat 22a. By the movement of the valve body 22c, the content liquid in the valve body accommodating portion 22 is pushed out to the impregnating material accommodating portion 21 and impregnated with the impregnating material 30. Then, when the valve body 22c contacts the valve seat 22a, the supply of the content liquid from the valve body accommodating portion 22 to the impregnating material 30 is restricted. That is, as the valve body 22c moves up and down, a fixed amount of content liquid is supplied to the impregnation material 30. In this state, by pressing the impregnating material 30 against the coated portion, an appropriate amount of the content liquid can be applied to the coated portion. Furthermore, the container body 2 to which the top cover 4 is attached can be turned upside down and shaken moderately, thereby impregnating the impregnating material 30 with the content liquid in advance.

If the content liquid is difficult to flow out during use of the coating container 1, the container body 2 may be temporarily put into an upright state and then used upside down, and the impregnating material 30 may be impregnated with the content liquid again. Here, in this embodiment, the content liquid supply tank 22a1 is formed in the valve seat 22a. The content liquid supply tank 22a1 can supply a small amount of content liquid from the valve body housing portion 22 to the impregnating material 30 even when the valve body 22c is in contact with the valve seat 22a. Therefore, even if it is difficult for the content liquid to flow out during use of the coating container 1, the number of operations such as impregnating the content liquid with the impregnating material 30 again by changing the container body 2 to the upright state and the inverted state can be reduced.

As described above, in the upright state where the container body 2 is on the lower side and the impregnating material 30 is on the upper side, the valve body 22c is supported by the valve body support portion 22b, and the communication groove 50 provided in the center plug member 20 The container body 2 communicates with the outside, so the pressure in the container body 2 is released. Therefore, when the coating container 1 is used, the discharge of the content liquid caused by the pressure difference between the inside and the outside of the container body 2 does not occur. In addition, when the container body 2 changes from the upright state to the inverted state, the valve body 22c is moved up and down to squeeze a fixed amount of the content liquid in the valve body housing portion 22 to the impregnated material housing portion 21. Then, when the valve body 22c contacts the valve seat 22a, the supply of the content liquid from the valve body accommodating portion 22 to the impregnating material 30 is restricted, so that the impregnating material 30 can be impregnated excessively to prevent dripping.

In this manner, the coating container 1 according to the present embodiment described above is configured to include: a container body 2 that contains the content liquid; a cylindrical intermediate plug member 20 that is attached to the mouth portion 10 of the container body 2; and an impregnating material 30, which is embedded inside the middle plug member 20 and can be impregnated with the content liquid; the middle plug member 20 includes: an impregnating material accommodating portion 21 that accommodates the impregnating material 30 in a state where the front end portion 30a protrudes; and the valve body accommodating portion 22 , Which communicates with the impregnated material accommodating portion 21, and has a valve seat 22a on the impregnated material accommodating portion 21 side, and a valve body support portion 22b on the container body 2 side, and the valve body 22c is movably arranged on the valve seat 22a and the valve body Between the support portions 22b; and the middle plug member 20 is formed with a communication groove 50 formed between the valve body 22c and the valve body accommodating portion 22 in a state where the valve body 22c is supported by the valve body support portion 22b The gap allows the container body 2 to communicate with the outside via the valve body accommodating portion 22 and the impregnating material accommodating portion 21. Thereby, it is possible to obtain a coating container 1 that can apply an appropriate amount of content liquid to a portion to be coated and has excellent usability.

(Second embodiment) Next, the second embodiment of the present invention will be described. In the following description, components that are the same as or equivalent to the above-mentioned embodiments are denoted by the same symbols and their descriptions are simplified or omitted.

As shown in FIG. 3, the coating container 1A of the second embodiment is different from the above-described embodiment in that the center plug member 20 has the first center plug member 20A and the second center plug member 20B.

The first intermediate plug member 20A is formed with an impregnated material accommodating portion 21. The impregnating material accommodating portion 21 of the second embodiment has a structure in which the above-mentioned fitting rib 21a and the supporting rib 45 are integrally formed and are continuously provided with each other. The first mid-bolt member 20A includes the flange portion 40, the fitting cylindrical portion 41, and the second cylindrical portion 43.

The second intermediate plug member 20B is formed with a valve body accommodating portion 22. The second middle plug member 20B corresponds to the first cylindrical portion 42 and is a member different from the first middle plug member 20A. The second intermediate plug member 20B is formed in a topped cylindrical shape in which a through hole 24 is formed in the top wall. The second intermediate plug member 20B and the through hole 24 are arranged coaxially with the container axis O as a common axis.

The second intermediate plug member 20B has a second flange portion 71 that is in contact with the opening edge of the lower end of the fitting cylindrical portion 41, is continuously provided on the radially inner end edge of the second flange portion 71, and is fitted into the fitting cylindrical portion 41. The second fitting cylindrical portion 72 on the inner circumferential surface of the lower end portion, and the top cylindrical portion 73 continuously provided on the upper end portion of the second fitting cylindrical portion 72. The second flange portion 71 is formed in an annular shape extending radially outward from the lower end opening edge of the second fitting cylindrical portion 72. The second fitting cylindrical portion 72 extends upward from the second flange portion 71, and the outer peripheral surface of the second fitting cylindrical portion is undercut fitted to the inner peripheral surface of the fitting cylindrical portion 41.

The top cylinder part 73 has a smaller diameter than the second fitting cylinder part 72. That is, the outer diameter of the top cylinder 73 is smaller than the outer diameter of the second fitting cylinder 72. A step is formed between the topped cylinder 73 and the second fitting cylinder 72. The topped cylindrical portion 73 is arranged in non-contact with the fitting cylindrical portion 41 (first middle plug member 20A). The above-mentioned through hole 24, the valve seat 22a, and the content liquid supply groove 22a1 are formed in the top cylinder portion 73. In addition, the rib-shaped valve body supporting portion 22b is formed from the top cylinder portion 73 to the second fitting cylinder portion 72.

According to the coating container 1A configured as described above, if the top cover 4 is removed from the mouth portion 10 of the container body 2, the gas pressurized inside the container body 2 enters the valve body housing portion from the bottom opening of the second intermediate plug member 20B In 22, after passing through the first communication groove 51 of the gap of the valve body support portion 22b in the axial direction, the first impregnated material accommodating portion 21 is entered through the through hole 24 and the communication hole 23. After the gas entering the impregnated material accommodating portion 21 passes through the second communication groove 52 of the gap between the support ribs 45 in the radial direction, it passes through the third communication groove 53 of the gap between the fitting ribs 21a in the axial direction. The top opening of 20A is released to the outside. Therefore, when the top cover 4 is removed, the pressure of the container body 2 is released, and the pressure difference between the inside and the outside of the container body 2 disappears. Therefore, according to the second embodiment, it is possible to obtain the same operational effects as the above-mentioned embodiment. In addition, the first middle plug member 20A and the second middle plug member 20B can be configured with different materials.

(Third Embodiment) Next, a third embodiment of the present invention will be described. In the following description, components that are the same as or equivalent to the above-mentioned embodiments are denoted by the same symbols and their descriptions are simplified or omitted.

As shown in FIG. 4, the coating container 1B of the third embodiment differs from the above embodiment in that the communication groove 50 is formed in the valve body 22c1.

The valve body 22c1 of the third embodiment is formed into an aspherical shape. Specifically, the valve body 22c1 is a rotating body centered on the container axis O, and is formed in a bag shape or a bullet shape. The valve body 22c1 has a cylindrical guide surface 22c2 guided by the peripheral wall 22d of the valve body accommodating portion 22, and a communication groove 50 is formed on the guide surface 22c2. The communication groove 50 of the third embodiment has a second communication groove 52 formed in the impregnated material accommodating portion 21, a third communication groove 53 also formed in the impregnated material accommodating portion 21, and a valve body accommodating portion 22 formed in the The fourth communication groove 54 of the valve body 22c1.

The peripheral wall 22d of the valve body accommodating portion 22 extends cylindrically in the direction of the container axis O and connects the valve seat 22a and the valve body support portion 22b. The inner wall surface of the peripheral wall 22d becomes a smooth peripheral surface, and no groove or the like extending in the direction of the container axis O is formed. The valve body support portion 22b of the third embodiment protrudes radially inward from the inner wall surface of the peripheral wall 22d. In addition, in the valve body support portion 22b, as in the above embodiment, a groove or the like extending in the direction of the container axis O may be formed, and the valve body support portion 22b may be rib-shaped.

In the valve body 22c1, the outer diameter of the guide surface 22c2 is slightly smaller than the inner diameter of the peripheral wall 22d. As a result, in the valve body accommodating portion 22, the valve body 22c1 can be rotated around the container axis O, but the valve body 22c1 cannot be rotated upside down, that is, the valve around the axis crossing the container axis O The rotation of the body 22c1. In other words, the valve body 22c1 can rotate about the container axis O in the valve body accommodating portion 22. However, the valve body 22c1 cannot be rotated in the valve body accommodating portion 22 in such a manner that the upper and lower parts of the valve body 22c1 are reversed, that is, it cannot be rotated about an axis crossing the container axis O, for example. The fourth communication groove 54 is formed to extend above and below the cylindrical guide surface 22c2, and is formed to be continuously provided with a lower hemispherical lower end surface 22c3 below the lower end of the guide surface 22c2.

As shown in the plan view of the valve body 22c1 of FIG. 5, a plurality of fourth communication grooves 54 are formed on the guide surface 22c2 of the valve body 22c1 at intervals in the circumferential direction (six in the present embodiment). Six fourth communication grooves 54 merge with each other at the center of the lower end surface 22c3 (container axis O). Furthermore, it is not necessary that all of the six fourth communication grooves 54 merge at the center of the lower end surface 22c3, as long as at least one set of fourth communication grooves 54 are arranged in a point-symmetrical manner across the container axis O to merge.

Returning to FIG. 4, a hemispherical upper end surface 22c4 continuously provided on the upper end of the guide surface 22c2 is formed with a bottomed hole 22c5 extending in the direction of the container axis O. The bottomed hole 22c5 is formed in the center of the valve body 22c1. Specifically, the bottomed hole 22c5 is formed in the radial center of the valve body 22c1. In addition, for example, after the valve body 22c1 is resin-molded, the bottomed hole 22c5 becomes a hollow hole. In addition, the bottomed hole 22c5 forms a space where the valve body 22c1 can be deformed by reducing the diameter of the valve body support portion 22b when the valve body 22c1 is inserted from the lower end of the valve body accommodating portion 22. That is, when the valve body 22c1 passes through the valve body support portion 22b, the valve body support portion 22b is temporarily elastically deformed in such a manner that the valve body 22c1 is reduced in diameter, in other words, the space formed by the bottomed hole 22c5 is temporarily oriented radially Inside shrink. Also, the diameter of the bottomed hole 22c5 is smaller than the diameter of the communication hole 23. Thereby, the upper end surface 22c4 of the valve body 22c1 can be in close contact with the valve seat 22a in the circumferential direction.

According to the coating container 1B configured as described above, when the container body 2 is in the upright state, the valve body 22c is supported by the valve body support portion 22b, and the container body 2 communicates with the outside through the communication groove 50. That is, the gas pressurized inside the container body 2 enters the valve body accommodating portion 22 from the bottom opening of the first cylindrical portion 42 and passes through the fourth communication groove 54 formed in the valve body 22c1 in the axial direction After the gap between the valve body 22c1 and the peripheral wall 22d, it enters the impregnated material accommodating portion 21 through the communication hole 23. The gas entering the impregnated material accommodating portion 21 passes through the second communication groove 52 of the gap between the support ribs 45 in the radial direction, and then passes through the third communication groove 53 of the gap between the fitting ribs 21a in the axial direction from the second cylindrical portion The top opening of 43 is released to the outside. Therefore, the pressure of the container body 2 is released, and the pressure difference between the inside and the outside of the container body 2 disappears.

Here, the valve body c1 is formed in an aspheric shape, and has a guide surface 22c2 guided by the peripheral wall 22d of the valve body accommodating portion 22, and a fourth communication groove 54 is formed in the guide surface 22c2 of the valve body 22c1. Therefore, for example, when the coating container 1B is used, the container body 2 is brought upside down, whereby even if the valve body 22c1 moves up and down, the valve body 22c1 can be rotated about the container axis O in the valve body accommodating portion 22, but it cannot be performed as a valve. The body 22c1 is turned upside down, that is, it cannot be rotated about the axis crossing the container axis O. Therefore, the posture of the valve body 22c1 is maintained at a fixed posture, and the pressure release through the container body 2 formed in the fourth communication groove 54 of the valve body 22c1 can be reliably performed.

In addition, the constituent elements of the above-mentioned embodiments can be appropriately replaced with well-known constituent elements without departing from the gist of the present invention.

For example, in the above embodiment, although the structure in which the valve body moves within the valve body accommodating portion by its own weight has been described, it is not limited to this. For example, the valve body may be configured to move in the valve body accommodating portion by pressurization due to the squeeze deformation of the container body.

In addition, for example, in the above-described first and second embodiments, the configuration in which the valve body is a sphere is described, and in the above-described third embodiment, the valve body is a rotating body (bag-shaped) centered on the container axis. Or bullet-shaped), but not limited to this. For example, the valve body may have a cylindrical shape. That is, if the valve body can be moved in the valve body accommodating portion, the shape of the valve body is not limited.

In addition, it is not limited to the structure in which the communication groove is formed only in one of the valve body accommodating portion or the valve body. For example, by combining the configuration of the first and second embodiments and the configuration of the third embodiment, a communication groove may be formed in both the valve body accommodating portion and the valve body.
