[0001]

[Industrial applications]

 The present invention relates to a brush-type cosmetic liquid application tool used for applying makeup such as eye shadows, eye liners, and concealers.

[0002]

[Prior art]

 Generally, various types of brush-type cosmetic liquid application tools of this type have been proposed. For example, the configuration shown in FIG. 13 is well known as a conventional example. This conventional cosmetic application tool is composed of a brush tip 1 made of a porous felt or the like, a holder 2 having an empty chamber in the center, a tail plug 3 for closing the rear end of the holder 2 and a tip of the holder. It is composed of a cap 4 that covers the brush tip 1. The tip of the holder 2 has a narrow inner diameter due to the provision of the narrowed portion 5. The writing tip 1 is fitted in the narrowed portion 5, and the rear end of the writing tip 1 is in the hollow portion of the holder 2. As a matter of fact, the batting 6 for impregnating the stock solution is packed. The padding 6 includes purified water, butylene glycol, oleic acid, naphthenic acid, sodium naphthenate, sodium dodecylbenzene sulfonate, sodium oleate, methylparaben, quaternium-15, propylparaben, ethylenediamine 4 disodium acetate. , Iron oxide, and a plurality of pigments such as bentonite, ultramarine blue, titanium dioxide, and mica. In addition, an air introduction hole 7 is formed on the tip end side of the holder 2 in order to make the extraction of the concentrated makeup solution good. A tail plug 3 is fitted in the rear end opening of the holder 2. The cap 4 is provided so as to be selectively attachable to the distal end narrowing portion 5 of the holder 2 and the tail plug 3. The eyeliner configured as described above can apply the pigment impregnated into the batting by removing the cap 4 and attaching the brush tip 1 to the periphery of the eye.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional eyeliner, the pigment impregnated into the batting, purified water and the like are discharged from the porous tips and applied. Therefore, since batting is used in the filling part of the cosmetic liquid concentrate, there is a structural disadvantage that the extraction time varies due to the difference in each molecular weight in the cosmetic liquid concentrate, and the pigment separates and the color changes. Was.

In addition, the water-based eyeliner is provided with an air introduction hole 7 in the vicinity of the writing tip in order to facilitate the ejection of the pigment. For this reason, it was necessary to secure an air passage from the tip of the brush to the tail of the brush, and it was not possible to fill the inner diameter of the holder 2 with the batting. Therefore, as a solution to these drawbacks, it has been proposed to provide a makeup stock solution in the tank and pressurize the tip of the writing brush when the cap is attached in order to prevent leakage of the solution during storage.

However, when pressure is applied to prevent liquid leakage, pressure is applied when the cap is attached, but pressurized air gradually escapes and conversely when the cap is pulled out. In addition, there was a drawback that the tip of the brush became a negative pressure and promoted liquid leakage. In addition, there is a drawback in that the tank is heated when it is held by hand and the air in the tank expands, causing liquid leakage.

An object of the present invention was made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a tool for applying a cosmetic liquid which prevents liquid leakage during cap removal and insertion and which prevents the brush tip from touching air and drying. It is in. Another object of the present invention is to provide a cosmetic application tool that is not affected by temperature changes even if it is gripped with a hand.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a brush tip made of a porous member such as felt, a brush tip holding member for holding the brush tip, a small amount tank connected to the brush tip holding member for storing a makeup stock solution, A sphere contained in the small amount tank, a main body cylinder for holding the small amount tank, a cap having substantially the same diameter as the main body cylinder, an interior cap made of a soft member mounted in the cap, and the cap And a sleeve member that is inserted from above the interior cap, and the interior cap is configured to be supported by a flexible member so as to be movable in the axial direction.

[0008]

[Action]

 With the cosmetic application tool according to the present invention, the stock solution is stored in a small tank, and the tip of the brush is sealed by the internal cap, so liquid leakage and drying can be prevented. In addition, since the inner cap moves in the axial direction, it is possible to prevent negative pressure from being generated when the writing tip is pressed and removed when the cap is inserted and fitted.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, a tool 10 for applying a cosmetic liquid includes a brush tip 11, a brush tip holding member 12 that holds the brush tip 11, a small amount tank 13 for storing a makeup stock solution connected to the brush tip holding member, and a flow rate adjusting member built in the tank. 14, a body cylinder 15 for holding the small amount tank with a predetermined gap, a cap 16 having a diameter substantially the same as the body cylinder, an inner cap 17 made of a soft member mounted in the cap, the cap It is composed of a sleeve member 18 and the like which is inserted from above the interior cap.

Here, the tip of the writing brush 11 is made of felt or the like made of a permeable material and has a spindle-shaped tip. The brush tip holding member 12 holds the brush tip with a tapered mounting portion 12a, and is fitted into the small amount tank 13 with a connecting portion 12b. The small amount tank 13 has a spherical body 14 made of steel, stainless steel or the like inserted therein. A tail plug 19 is fitted to the rear end of the small quantity tank to seal the rear end of the small quantity tank. Further, a flange portion 13a is provided at a predetermined position of the body portion of the small amount tank 13, for example, in the vicinity of the middle thereof, to prevent the main body cylinder 15 from entering more than a predetermined amount in the cap direction. The main body cylinder 15 is a hollow cylinder and has a diameter that makes it easy to hold by hand.

On the other hand, the cap 16 has a cylindrical shape with one end open, and an interior cap 17 that surrounds the periphery of the writing tip 11 is fitted inside the cap 16. The inner cap 17 includes a hermetically sealed cap 17a having a spindle-shaped recess that surrounds the tip of the writing brush 11, a cylindrical base 17b fitted in the inner cylindrical part of the cap 16, and a thin-walled cylindrical part 17c connecting the two together. It is configured to Here, the thin-walled cylindrical portion 17c maintains the cylindrical state in the unloaded state, but when it is loaded, it deforms into a bellows shape and retracts the sealing cap 17a.

FIG. 3 shows a state in which the ring 20 is inserted into the flange portion 13a and the cap 16 is temporarily fixed. Before the cosmetic application tool is assembled and the cosmetic liquid is filled, it is not necessary to keep the brush tip 11 in contact with the sealing cap 17a. Therefore, the ring 16 is used to temporarily fix the cap 16. . By doing so, the elasticity of the thin-walled cylindrical portion 17c can be maintained forever.

Next, regarding the procedure for using the eyeliner, which is a tool for applying a cosmetic solution constructed as described above, first, when the eyeliner is not in use, the cap 16 is attached as shown in FIGS. Keep it closed. When the cap 16 is closed, the writing tip 11 is sealed by the cap 17 a of the interior cap 17 and the tip of the writing tip holding member 12. At this time, when the tip of the writing brush holding member comes into contact with the sealing cap 17a and a predetermined force or more is applied, the thin cylindrical portion 17c buckles and retracts, so that the sealing cap 17a is not pressurized more than necessary. Absent. At this time, the brush tip 11 is sealed with the sealing cap 17a and is not dried.

For use in makeup, the cap 16 is removed to expose the brush tip 11 from which the pigment has exuded (see FIG. 2). At this time, since the small amount tank 13 and the main body cylinder 15 have a predetermined gap and have a double structure, it is possible to prevent the volume change due to the expansion of air even when grasped with a hand. Further, since the sealing cap 17a moves forward following the writing tip 11 when the length is a predetermined length or longer, the writing tip portion does not become a negative pressure when the cap 16 is removed. Therefore, the cosmetic concentrate will not be excessively discharged due to negative pressure. When the cap 16 is closed again after applying the pigment around the eye with the brush tip, the brush tip 11 is sealed with the sealing cap 17a. In this way, the brush tip 11 is sealed with little pressure and is ready for the next use.

Further, when the brush tip 11 is turned up, the sphere 14 of the small amount tank 13 comes to the bottom and the cosmetic solution also descends to the bottom on the side of the tail plug 19, so that the cosmetic solution does not blow out. When the brush tip 11 is directed downwards, the sphere 14 closes the entrance of the cosmetic liquid flowing to the brush tip, so that excessive flow of the cosmetic liquid can be prevented. Furthermore, since a small amount of the cosmetic liquid is stored in the tank 13, the liquid holding force of the brush tip 11 can be sufficiently endured.

FIG. 5 is an overall sectional view showing another embodiment of the present invention. In the figure, a tool 10 for applying a cosmetic liquid includes a writing tip 11 made of a porous member such as felt, a writing tip holding member 12 that holds the writing tip 11, and a flow rate adjusting member that is inserted into a rear end portion of the writing tip holding member 12. The adjuster 21 is provided, and is connected to the small amount tank 13 via the adjuster (introducing core) 21.

As described above, when the small amount tank 13 is connected through the adjuster 21 which is a flow rate adjusting member, the flow rate adjusting member can be used to detect the difference in the particle size of the pigment contained in the cosmetic concentrate and the difference in the viscosity of the dispersant. By changing the bubble density and length of a certain adjuster 21, it is possible to adjust the discharge amount of the makeup concentrate. This works similar to the sphere 14 of the first embodiment.

FIG. 10 is a partially cutaway view of the adjuster 30 in a mounted state showing another embodiment, FIG. 11 is a sectional view taken along the line AA, and FIG. 12 is a plan view thereof. Here, the adjuster 30 is composed of a core member 33 in which both sides of a cylinder are cut out in parallel, and an outer cylinder 32 mounted on the core member 33. The outer cylinder 32 has a large diameter portion 32a, and a groove 31 is engraved in the large diameter portion 32a. Therefore, even if the large diameter portion 32a is fitted into the inner diameter portion of the writing brush holding member 12, the gas-liquid flow can be secured.

In the case of such a configuration, since the double passages for the air and the cosmetic liquid can be formed as dedicated passages, respectively, the flow rate can be adjusted smoothly. In the above embodiment, an example in which the cutout portions of the core material 33 are parallel to each other has been described, but the present invention is not limited to this, and U-shaped or V-shaped grooves may be formed.

6 to 7 are cross-sectional views of essential parts of a cosmetic application tool according to another embodiment of the present invention. In this embodiment, a sleeve member 22 having a slope 22a that is fitted over the interior cap is provided in the cap 16. With this configuration, when the cap 16 is attached to the writing tip 11, the writing tip 11 does not hit the edge of the interior cap 17 and is not bent (see FIG. 7). That is, even if the tip of the writing tip 11 is inserted into the cap 16 at a bent angle, the tip of the writing tip 11 is not damaged because it is corrected by the inclined surface 22a of the sleeve member 22.

FIGS. 8 to 9 are cross-sectional views of essential parts showing a cosmetic liquid application tool according to another embodiment of the present invention. In this embodiment, an inner cap 24 made of a soft material is attached to the cap 23, and a cylindrical sleeve member 25 is fitted over the inner cap 24. Here, the interior cap 24 is integrally configured with a cylindrical sealing cap 24a for accommodating the writing tip 11, a cylindrical base portion 24b inserted into the bottom portion of the cap 23, and a thin cylindrical portion 24c for connecting both. Further, the sleeve member 25 has a substantially cylindrical shape, and its end portion is enlarged in a tapered shape. Therefore, when installed inside the cap 23, the enlarged taper portion 25a is located on the outer periphery of the inlet portion of the cylindrical sealing cap 24a.

In the case of the above configuration, when the brush tip 11 is inserted into the cap 23, the brush tip 11 can be smoothly inserted without being caught on the side edge. In addition, as with the first embodiment, when the brush tip 11 is inserted, the cylindrical seal cap 24a receives the brush tip 11 (see FIG. 8), and the brush tip 11 enters further. Then, the tip of the mounting portion 12a comes into contact with the cylindrical sealing cap 24a, and the thin cylindrical portion 24c buckles, whereby the cylindrical sealing cap 24a retracts. Therefore, the inside of the cylindrical sealing cap 24a accommodating the brush tip 11 will not be pressurized more than necessary. Also, when the brush tip 11 is removed, the cylindrical sealing cap 24a moves forward with the retreat of the mounting portion 12a, so that the cylindrical sealing cap 24a in which the brush tip 11 is stored becomes a negative pressure and the cosmetic concentrate is ejected. Nothing.

[Effect of device]

 As described in detail above, according to the cosmetic liquid application tool of the present invention, the writing tip made of a porous member such as felt, the writing tip holding member for holding the writing tip, and the writing tip holding member are connected. The interior includes a small amount tank for storing the makeup stock solution, a main body cylinder for holding the small amount tank, a cap having substantially the same diameter as the main body cylinder, and an interior cap made of a soft member mounted in the cap. Since the cap is supported by a flexible member so as to be movable in the axial direction, the tip of the writing brush is not pressed more than necessary when the cap is attached. Also, when the cap is pulled out, the interior cap moves forward following the brush tip, so it is possible to prevent the liquid concentrate from leaking or blowing out without negative pressure. Further, since the sphere 14 moves in the tank 13 in a small amount and blocks the entrance of the cosmetic liquid flowing to the brush tip, it is possible to prevent the cosmetic liquid from flowing out excessively.

Further, a brush tip made of a porous member such as felt, a brush tip holding member for holding the brush tip, a small amount tank for storing the makeup stock solution connected to the brush point holding member, and a built-in small volume tank. A spherical body, a main body cylinder for holding the small amount tank, a cap having substantially the same diameter as the main body cylinder, an inner cap made of a soft member mounted in the cap, and the inner cap inserted into the cap from above. Since it is equipped with a sleeve member, even if the tip of the brush is tilted when the cap is attached, it is corrected by the sleeve member and does not bend. Further, since the tank has a double structure, it is possible to prevent the volume change due to air expansion. Also, since it is a small amount tank, it can withstand the liquid holding power of the writing brush.
