Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional coating container, when the viscosity of the content liquid is low, when the coating container is in an inverted posture, the content liquid is likely to drip through the communication path, and the content liquid may adhere to a location other than the coated portion, for example, or may be applied to the coated portion in a large amount.

[0005] The present invention provides a coating container capable of suppressing the dripping of the content liquid through the communication path when the coating container is in an inverted posture.

Means for Solving the Problems

[0006] A coating container according to one aspect of the present invention comprises a container body for containing liquid contents, a cylindrical stopper member attached to the mouth of the container body, and an impregnating material attached to the inside of the stopper member and capable of impregnating the liquid contents, wherein the stopper member comprises a containment cylinder for containing the impregnating material with its upper end protruding, and a communication cylinder that connects the inside of the containment cylinder and the inside of the container body to each other, a communication passage is provided between the containment cylinder and the impregnating material that connects the inside of the communication cylinder and the upper end opening of the containment cylinder to each other, and a plurality of mesh bodies are provided on the inside of the communication cylinder at intervals in the vertical direction.

[0007] Since multiple mesh bodies are provided on the inside of the connecting cylinder at intervals in the vertical direction, when the liquid contents of the container body flow into the connecting cylinder and reach the mesh bodies, a liquid film can be formed on the mesh bodies. This makes it difficult for the liquid contents of the connecting cylinder to reach the connecting passage even if the coating container is simply placed in an inverted position. When the inverted coating container is shaken up and down, or when the internal pressure of the container body is increased, the liquid contents pass through the mesh, flow into the connecting passages, and impregnate the impregnating material, thereby being applied to the area to be coated. [Effects of the Invention]

[0008] According to one aspect of the present invention, when the coating container is in an inverted position, it is possible to suppress the dripping of the liquid contents through the connecting passage. [Brief explanation of the drawing]

[0009] [Figure 1] This is a longitudinal cross-sectional view of a coating container shown as one embodiment. [Modes for carrying out the invention]

[0010] A coating container according to one embodiment of the present invention will be described below with reference to the drawings. As shown in Figure 1, the coating container 1 according to this embodiment comprises a container body 11, an inner stopper member 12, an impregnation material 13, and a cap 14. The container body 11 is formed in a bottomed cylindrical shape, the inner stopper member 12 is formed in a cylindrical shape, the impregnating material 13 is formed in a solid rod shape, and the cap 14 is formed in a topped cylindrical shape. The container body 11, the inner stopper member 12, the impregnating material 13, and the cap 14 are arranged coaxially with a common axis.

[0011] Hereinafter, this common axis will be referred to as the container axis O, the side of the container body 11 with its opening 11a aligned with the container axis O will be referred to as the upper side, the side with its bottom 11b aligned with the container axis O will be referred to as the lower side, and the direction along the container axis O will be referred to as the vertical direction. The direction that intersects the container axis O when viewed from the vertical direction will be referred to as the radial direction, and the direction that circles around the container axis O when viewed from the vertical direction will be referred to as the circumferential direction.

[0012] The liquid contents are contained within the container body 11. The liquid contents are not particularly limited, but examples include hair growth agents, antifungal medications, cosmetics, and other liquids applied to the body or skin. A male threaded portion is formed on the outer surface of the opening 11a of the container body 11. The cap 14 is detachably attached to the opening 11a. The cap 14 has a female thread that screws onto the male thread of the opening 11a. Alternatively, the cap 14 may be detachably fitted onto the opening 11a. The inner surface of the cap 14 is in liquid-tight contact with the upper end of the inner stopper member 12.

[0013] The impregnating material 13 is installed inside the inner stopper member 12. Examples of the impregnating material 13 include porous materials such as sponges, or fibrous materials in which synthetic fibers are solidified with a resin solution and can be impregnated with the liquid contents using capillary action. However, it is not limited to these cases, as long as it can impregnate with the liquid contents.

[0014] The inner stopper member 12 is attached to the mouth portion 11a of the container body 11. The inner stopper member 12 comprises a housing cylinder 15 and a connecting cylinder 16. A flange portion 12b is formed at the connection point between the connecting cylinder 16 and the housing cylinder 15, projecting radially outward and extending continuously around the entire circumference. The flange portion 12b is positioned at the upper opening edge of the mouth portion 11a.

[0015] An impregnating material 13 is housed within a housing cylinder 15. The upper end of the impregnating material 13 protrudes upward from the housing cylinder 15. Multiple longitudinal ribs 18 are formed on the inner circumferential surface of the housing cylinder 15, protruding radially inward and extending vertically, at intervals in the circumferential direction. The outer circumferential surface of the impregnating material 13 is supported by the radially inner end faces of the longitudinal ribs 18.

[0016] The containment cylinder 15 is formed in the shape of a bottomed cylinder having an annular bottom wall 15a. Multiple support ribs 17 projecting upward are formed on the inner peripheral edge of the bottom wall 15a at intervals in the circumferential direction. The lower end surface of the impregnating material 13 is supported on the upper surface of the support ribs 17. The bottom wall 15a extends upward as it moves inward in the radial direction. The gap between the inner circumferential surface of the housing cylinder 15 and the outer circumferential surface of the impregnating material 13, as well as the gap between the upper surface of the bottom wall 15a of the housing cylinder 15 and the lower end surface of the impregnating material 13, constitute a communication passage 21 that connects the inside of the communication cylinder 16 and the upper end opening 15b of the housing cylinder 15 to each other.

[0017] The connecting tube 16 extends downward from the bottom wall 15a of the containment tube 15. The connecting tube 16 is liquid-tightly fitted into the mouth 11a of the container body 11. The connecting tube 16 connects the inside of the containment tube 15 and the inside of the container body 11 to each other. Multiple mesh bodies 23 are provided on the inside of the connecting tube 16 at intervals in the vertical direction. The mesh bodies 23 cover the entire radial area inside the connecting tube 16. The mesh bodies 23 are made of, for example, resin (nylon, etc.) or metal. The size of the mesh openings of the mesh bodies 23 is set appropriately according to the properties of the liquid contents, etc.

[0018] In the illustrated example, two mesh bodies 23 are provided; the upper mesh body 23 is located inside the upper end of the connecting cylinder 16, and the lower mesh body 23 is located inside the lower part of the connecting cylinder 16. The mesh sizes of the two mesh bodies 23 are the same, but they may be different.

[0019] Inside the communication tube 16, two cylindrical bodies 22 are fitted and fixed in a state where they abut against each other in the vertical direction. Note that the two cylindrical bodies 22 may be provided with a gap in the vertical direction. The cylindrical body 22 is arranged coaxially with the container axis O. An upper mesh body 23 is attached to the upper end opening edge of the upper cylindrical body 22, and a lower mesh body 23 is attached to the lower end opening edge of the lower cylindrical body 22.

[0020] Among the upper mesh bodies 23, the portion located radially inside the upper end opening edge of the upper cylindrical body 22 is separated downward from the lower surface of the bottom wall 15a of the storage cylinder 15. The outer peripheral edge portion of the upper mesh body 23 is sandwiched in the vertical direction by the upper end opening edge of the upper cylindrical body 22 and the lower surface of the bottom wall 15a of the storage cylinder 15. Note that the upper mesh body 23 may be located below the upper end portion of the communication tube 16.

[0021] The lower mesh body 23 is located above the lower end portion of the communication tube 16. Note that the lower mesh body 23 may be provided inside the lower end portion of the communication tube 16. The outer peripheral edge portion of the lower mesh body 23 is sandwiched in the vertical direction by the lower end opening edge of the lower cylindrical body 22 and the locking projection 16a formed on the inner peripheral surface of the communication tube 16. Note that the locking projection 16a may not be formed on the inner peripheral surface of the communication tube 16.

[0022] As described above, according to the coating container 1 of the present embodiment, since a plurality of mesh bodies 23 are provided inside the communication tube 16 at intervals in the vertical direction, when the content liquid in the container body 11 flows into the communication tube 16 and reaches the mesh body 23, it becomes possible to form a liquid film on the mesh body 23. Just by turning the coating container 1 upside down, it is possible to make it difficult for the content liquid in the communication tube 16 to reach the communication path 21. When the coating container 1 in the upside-down posture is shaken up and down or the internal pressure of the container body 11 is increased, the content liquid passes through the mesh body 23, flows into the communication path 21, and is impregnated into the impregnating material 13, and then is applied to the coated portion.

[0023] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0024] For example, three or more mesh bodies 23 may be provided with spacing between them in the vertical direction. Alternatively, the cylindrical body 22 may be omitted, and the mesh body 23 may be directly attached to the inner surface of the connecting cylinder 16.

[0025] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of Symbols]
