Description

DESCRIPTION TITLE OF THE INVENTION:

CONTAINER FOR COATING TOOL

TECHNICAL FIELD

[0001] The container for coating tool present invention relates to a container for coating tool in which a medicinal liquid or the like can be stored and which can directly apply the medicinal liquid or the like stored therein to an affected part or the like. In particular, the present mvention relates to a container for coating tool that can be preferably used for applying a medicinal liquid such as an athlete's foot medicine to a narrow site such as between toes, for example.

BACKGROUND ART

16002] Containers for coating a medicinal liquid or the like to a given narrow site are known (for example, see Patent Literature 1).

[0003] A conventional container for coating tool includes: a container body in which a medicinal liquid or the like is stored; an coating tool using a brush, a sponge, or the like; an mside plug which is mserted into a mouth of the container body; a nozzle body having a hollow convergent shape combined with the inside plug so as to be movable in an up-down direction relative to the inside plug; a screw-type attachment cap; and a holder integrated with the nozzle body. Here, the coating tool, the inside plug, the nozzie body, and the holder are attached to the mouth of the container body by means of the attachment cap. Further, when the nozzle body is lowered into the mnside plug, an opening which is open in a side face of the inside plug is closed with a lower end portion of the nozzle body. On the other hand, when the nozzle body is raised, the opening of the inside plug becomes open. When the attachment cap is rotated in a loosening direction, the nozzle body is raised to open the opening of the inside plug, thereby allowing the medicinal liquid in the container body to flow out of the leading end of the nozzle body, to be supplied to the coating tool. On the other hand, when the attachment cap is rotated m the reverse direction, the nozzle body is lowered, to be able to close the opening of the inside plug. It should be noted that, when not used, the coating tool is covered with an over cap different from the attachment cap.

SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION

L005] According to such a conventional container for coating tool, the medicinal liquid from the container 1s supplied to the coating tool by rotating, in use, the attachment cap in the loosening direction to open the opening of the inside plug, and the supply of the medicinal liquid the coating tool is cut off by rotating, after use, the attachment cap in the reverse direction to close the opening of the inside plug. Here, even when the opening of the inside plug is closed after use, a large amount of medicinal liquid remaining inside the nozzle body is continued to be supplied to the coating tool. Thus, there is a problem that the medicinal Hquid may be wasted or leak to the outside from the gap below the over cap. In addition, there is also a problem that the coating tool is easy to bend and coat to a narrow site is difficuit.

[0006] The present invention has been made in consideration of the problems in conventional containers for coating tool as described above. The present invention provides an container for coating tool which is less likely to cause waste or leak of the medicinal liquid after use compared with conventional containers for coating tool, and which allows easy cort of the medicinal liquid even to a narrow site,

SOLUTIONS TO THE PROBLEMS

{0007] The present invention comprising: a container body in which a medicinal liquid is stored; an inside plug which includes a nozzle cylinder and which is pressed into a mouth of the container body; an coating tool using a sponge member 1n which interconnecting cells are formed, the coating tool including an coating tool part which covers the nozzle cylinder; and a cap which is detachably mounted to the mouth, wherein the inside plug includes an outlet hole for the medicinal hquid which is open at a leading end of the nozzle cylinder, and the cap is configured to, when mounted to the mouth. close the outlet hole by pressing the coating tool part at a leading end face of the nozzle cylinder, and is configured to, when removed from the mouth, open the outlet hole to allow the medicinal liquid to ooze to a surface of the coating tool part.

[0008] In the present invention, the coating tool includes a flange extending toward an outer circumference direction formed at a lower end of the coating tool part, and is fixed to the inside plug via an attachment ring which confines the flange to a shoulder of the inside plug on which the nozzle cylinder stands.

[0609] [n the present invention, on an outer face of the coating tool part, either a plurality of annular projections projecting in series toward a circumference direction are provided or a plurality of grooves recessed in series in a symmetry axis direction are provided.

[0016] In the present invention, on an outer face of the nozzle cylinder, one or more ribs projecting in series toward a circumference direction for engaging the coating tool part are provided.

In the present invention, inside the cap, a protection skirt which houses the coating tool part is provided so as to hang,

ADVANTAGEOUS EFFECTS OF THE INVENTION

{0011} According to the present invention, the inside plug pressed into the mouth of the container body includes a nozzle cylinder, and at the leading end of the nozzle cylinder, an outlet hole for the medicinal liquid is open. Therefore, the medicinal liquid in the container body flows out through the outlet hole to ooze to a surface of the coating tool part covering the nozzle cylinder. Accordingly, the medicinal liquid can be applied to a given site via the coating tool part. The coating tool using a sponge member includes a coating tool part having a cylindrical shape whose inner diameter has a size that matches and is substantially the same as the outer diameter of the nozzle cylinder. The coating tool can cover the entire length of the nozzle cylinder with the upper end of the coating tool part closed. Thus, by the nozzle cylinder reaching a leading end portion of the coating tool part. the coating tool part does not bend unexpectedly, and thus, the medicinal liquid can be easily applied even to a narrow site.

However, it is preferable that the entire thickness of the coating tool including the coating tool part 1s substantiafly uniform.

[6012] When the cap is mounted to the mouth, the inner face of the top portion of the cap approaches the leading end face of the nozzle cylinder to press and compress the coating tool part at the leading end face of the nozzle cylinder, thereby closing the outlet hole. Therefore, there is no risk of the medicinal liquid in the container and the medicinal liquid in the nozzle cylinder flowing out through the outlet hole to be wasted after use. Since the coating tool using the sponge member has elasticity, if the cap 1s removed and the pressing force is released, the coating tool soon returns to its original shape. [0G13] The coating tool can be mtegrally fixed to the inside plug by confining the flange extending toward the outer circumference direction at the lower end of the coating tool part, to the upper face of the shoulder of the inside plug via the attachment ring. Thus, the coating tool does not unexpectedly come off the nozzle cylinder of the inside plug.

[0014] The coating tool part of the coating tool can have an increased outer surface area, by providing, on the outer face of the coating tool part, a plurality of annular projections projecting in series toward the circumference direction, or a plurality of grooves recessed in series mn the symmetry axis direction. Accordingly, operation of applying the medicinal liguid can be still easter. Further, if one or more ribs projecting in series toward the circumference direction for engaging the coating tool are provided on the outer face of the nozzle cylinder, an effect of preventing the coating tool from slipping off can be improved. [0015} The protection skirt provided so as to hang in the cap houses substantially the entirety of the coating tool part on the nozzle cylinder, thereby preventing quick evaporation, solidification, or the like of the medicinal liquid oozing to the surface of the coating tool part.

Therefore, the surface of the coating tool part can be maintained in a wet state with the medicinal liquid for a Jong time period. However, the inner diameter of the protection skirt is set to be slightly larger than the outer diameter of the coating tool part such that the coating tool part can be housed in the skirt with a slight gap therebetween.

DESCRIPTION OF EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. <Embodiment t>

[0018] As shown in FIG | and FIG 2, the container for coating tool includes a container body 10 in which a medicinal liquid is stored, an inside plug 20, a coating tool 30, an attachment ring 40, and a cap 50.

[0019] The container body 10 is a plastic container obtained by integrally molding a barrel 11 and a mouth 12 facing upward. On the outer periphery of the mouth 12, a male screw 13 for the cap 50 1s formed.

[0020] As shown in FIG 1 and FIG. 3, the inside plug 20 is a plastic component obtained by mtegrally molding a skirt part 21, a flange 22 extending toward the outer circumference direction, a shoulder 23, and a nozzle cylinder 24, and has a hollow body structure in an axial symmetry as a whole. [00213 The skirt part 21 is configured to be pressed into the mouth 12 of the container body 10. The outer diameter of the skirt part 21 has a size matches and is substantially the same as the inner diameter of the mouth 12. A lower portion of the outer periphery of the skirt part 21 has a gradually-reduced diameter in a downward direction. The outer diameter of the flange 22 is the same as the outer diameter of the upper end edge of the mouth 12. The shoulder 23 serves as a step-like connection part which connects the flange 22 having a large diameter and the nozzle cylinder 24 having a small diameter together. On the upper face of the shoulder 23, an engagement rib 23a for engaging the coating tool 30 is formed. On the periphery of the shoulder 23, an annular engagement part 23b for the attachment ring 40 is formed.

[06022] The nozzle cylinder 24 is provided so as to stand on the shoulder 23, and extends in an elongated manner in the symmetry axis direction of the inside plug 20. In a leading end face, which is flat, of the nozzle cylinder 24, an outlet hole 24a for the medicinal liquid is open, and a lower portion of the outlet hole 24a is open in a tapered shape.

[0023] The coating tool 30 is a sponge member which contains interconnecting cells and which is obtained by integrally molding a flange 32 extending toward the outer circumference direction to the lower end of a coating tool part 31 having a cylindrical shape. The length of the coating tool part 31 has a size that matches and is substantially the same as the length of the nozzle cylinder 24, and the inner diameter of the coating tool part 31 has a size that matches and is substantially the same as the outer diameter of the nozzle cylinder 24. The outer diameter of the flange 32 is the same as the outer diameter of the shoulder 23. Further, the leading end of the coating tool part 31 is closed by a flat face, and the peripheral edge portion of the flat face is rounded. Thus, the coating tool 30 is combined with the inside plug 20 without any gap therebetween, by covering the entire length of the nozzle cylinder 24.

[0024] The attachment ring 40 is a plastic component obtained by integrally molding a confining part 42 having a ring shape facing obliquely upward, to an upper portion of a body part 41 which can house the shoulder 23 of the inside plug 20. It should be noted that the coating tool part 31 of the coating tool 30 can be inserted through the confining part 42. On the inner periphery of the body part 41, an engagement part 41a having an annular shape which engages the engagement part 23b on the inside plug 20 side is formed. At the leading end of the confining part 42, a press rib 42a facing downward which corresponds to the engagement rib 23a on the inside plug 20 side is formed. Therefore, by inserting the nozzle cylinder 24 of the side plug 20 covered with the coating tool 30, through the confining part 42 from therebelow, and by causing the engagement parts 41a and 23b to be engaged with cach other, thereby integrally connecting the coating tool 30 and the inside plug 20 together, the attachment ring 40 can confine the flange 32 on the shoulder 23 between the engagement rib 23a and the press rib 42a via the confining part 42, thereby integrally fixing the coating tool 30 to the inside plug 20. [60257 The cap 50 is a plastic component whose top portion is formed in a dome shape, and whose outer periphery lower portion is provided with roulette 51 for slip prevention, and whose inner periphery lower portion is provided with a female screw 52. The female screw 52 fits the male screw 13 on the container body 10 side. Thus, the cap 50 is a screw-type cap that 1s attachable and detachable relative to the mouth 12 of the container body 10, via the female screw 52 and the male screw 13.

[0026] On the inner face of the top portion of the cap 50, a seal ring 33 projecting in a ring shape is formed. The seal ring 33 faces the leading end face of the nozzle cylinder 24 of the inside plug 20, via the coating tool part 31 of the coating fool 30. Therefore, when the cap 50 1s mounted to the mouth 12 of a container 10, the seal ring 53 presses and compresses the coating tool part 31 around the outlet hole 24a in the leading end face of the nozzie cylinder 24 into a ring shape, thereby being able to close the outlet hole 24a.

[0027] Inside the cap 50, a protection skirt 54 and a restriction skirt 55 are coaxially provided so as to hang. The protection skirt 54 can house substantially the entire length of the coating tool part 31 exposed above the attachment ring 40. The restriction skirt 55 having a larger diameter than that of the protection skirt 54 hangs outside the attachment ring 40, and reaches the flange 22 of the inside plug 20, thereby restricting the limit of the screwing amount of the cap 50 relative to the mouth 12. Ht should be noted that, in space 56 having a ring shape outside the protection skirt 34, a plurality of reinforcing plates (not shown) which connects the outer face of the protection skirt 54 to the inner face of the restriction skirt 55 may be radially arranged.

[0028] When the cap 50 is mounted to the mouth 12 with a medicinal liquid (not shown) stored in the container body 10, as shown in FIG. 3, the outlet hole 24a for the medicinal liquid at the leading end of the nozzle cylinder 24 of the inside plug 20 is closed. Thus, there is no risk of the medicinal liquid leaking outside.

[0029] As shown in FIG. 4, when the cap 50 is removed from the mouth 12, the coating tool 30 which has been pressed into a ring shape by the seal ring 53 of the cap 50 returns to its original shape due to elasticity thereof. As a result, the outlet hole 24a at the leading end of the nozzle cylinder 24 opens, and the medicinal liquid in the container body 10 flows out through the outlet hole 24a, and oozes to a surface of the coating tool part 31 of the coating tool 30 using the sponge member. Thus, by using a leading end portion of the coating tool part 31 of the coating tool 30, the medicinal liquid can be applied to a desired narrow site, and by using a peripheral side portion of the coating tool part 31, the medicinal liquid can be applied to a desired wide site.

When assuming that an athlete’s foot medicine is to be applied between toes, the length and the outer diameter of the coating tool part 31 projecting above the attachment ring 40 are preferably about 15 to 26 mm and about 6 to 10 mm, respectively.
