Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cosmetic tools, and particularly to an eyeliner for applying makeup around the eyes.

(Prior Art) Various cosmetic tools such as eyeshadow, mascara, and eyeliner have been proposed.

An example of a conventional eyeliner will be described below with reference to the accompanying drawings. Fig. 6 is a cross-sectional view showing the state with the cap removed, and Fig. 7 is a cross-sectional view showing the state with the cap attached. It consists of a holder 2 having a vacant chamber in the center, a tail plug 3 that closes off the rear end of the holder 2, and a cap 4 that is fitted to the tip of the holder and covers the pen tip 1. Here, the pen tip 1 is formed into a spindle shape using a porous material from which moisture can leak, such as felt or sponge. Moreover, the inner diameter of the tip of the holder 2 is tapered at the constriction part 5.
The pen tip 1 is fitted into this diaphragm portion 5. The hollow part of the holder 2 is filled with a filling 6 for impregnating the contents, and the filling 6 contains moisture, butylene glycol, oleic acid, naphthenic acid, sodium naphthenate, sodium dodecylbenzenesulfonate, It is impregnated with sodium oleate, methylparaben, quaternium-15, propylparaben, disodium ethylenediaminetetraacetate, iron oxide, and several pigments such as bentonite, ultramarine blue, titanium dioxide, mica, etc. Furthermore, an air introduction hole 7 is bored at the tip of the holder 2 . A tail plug 3 is fitted into the rear end opening of the holder 2 . Further, the cap is provided so as to be attachable to a portion of the end constriction portion 5 of the holder 2 and a portion of the tail plug 3.

The eyeliner configured as described above has the fourth
As shown in the illustration, with the cap removed, insert the pen tip 1.
By applying it around the eyes, the pigment impregnated into the batting can be sequentially applied.

(Problems to be Solved by the Invention) In the conventional eyeliner described above, the pigment, moisture, etc. impregnated in the batting are applied by leaching out from the porous tip. Therefore, while the eyeliner liquid is impregnated into the batting, it is exposed to air and therefore oxidizes. In addition, in the case of the batting type, the eyeliner liquid impregnated in the batting comes out from the pen tip, making it difficult to ensure a sufficient amount of discharge and making it difficult to write darkly.

Furthermore, since eyeliner is applied to the eyelids and around the eyes, it is necessary to prevent the growth of bacteria, but strong preservatives cannot be used. On the other hand, the use of strong preservatives is also restricted by the Pharmaceutical Affairs Law. Generally, preservatives release chlorine or ammonia when exposed to air and sterilize them, so conventional cotton-filled products inevitably require a large amount of preservative because the area exposed to air is large.

In addition, the water-based eyeliner is provided with an air introduction hole 7 near the pen tip in order to facilitate the leaching of the pigment. For this reason, an air passage must be ensured from the pen tip to the pen tail, making it impossible to fill the inner diameter of the holder 2 with the filling.
Note that the air introduction hole 7 is connected to the cap 4 at the tip of the holder 2.
The holder 2 is provided in the area covered by the
This is to prevent the filling filled inside from drying out.

Furthermore, in order to accommodate a large amount of pigment, the size of the holder must be increased, and increasing the length of the holder tends to promote separation of the pigment.

The object of the present invention was made in view of the above-mentioned drawbacks, and is to provide a safe eyeliner by sufficiently sterilizing the eyeliner with a weak and safe preservative to prevent the proliferation of germs. Another object of the present invention is to provide an eyeliner that can be written darkly by ensuring a sufficient amount of ejection from the pen tip. A further object of the present invention is that by changing the porosity of the pen tip, eyeliner liquids with different concentrations and viscosities can be used.
To provide eyeliners in various colors.

(Means for Solving the Problems) An eyeliner according to the present invention includes a pen nib made of a permeable material, a nib holder portion that holds the pen nib, and a pen tip holder portion connected to the rear end of the pen nib holder portion. It comprises a tank section storing eyeliner liquid, and a gas-liquid separation mechanism connected to the rear end of the tank section and having a number of annular grooves communicating with the tank section, the other end of which communicates with the outside air. , while supplying outside air into the tank containing the eyeliner liquid through the gas-liquid separation mechanism, only the air in the mixture of eyeliner liquid and air that is blown out when the air expands in the tank is removed. The eyeliner liquid is discharged to the outside and is captured by the annular groove.

Also, a pen nib made of a permeable material, a pen nib holder portion that holds the pen nib, and a flow rate adjustment portion that is built in the rear end of the pen nib holder portion and adjusts the supply of eyeliner liquid to the pen nib. , a tank part containing eyeliner liquid connected to the rear end of the flow rate adjusting part, and a large number of annular narrow grooves connected to the rear end of the tank part and communicating with the tank part; It is equipped with a gas-liquid separation mechanism whose end communicates with the outside air, and supplies outside air into the tank containing the eyeliner liquid through the gas-liquid separation mechanism, and removes the eyelids that blow out when the air expands in the tank. Only the air in the mixture of line liquid and air may be discharged to the outside, and the eye line liquid may be trapped in the annular groove.

(Function) As described above, since the eyeliner according to the present invention can contain the eyeliner liquid as a liquid, it can be equipped with a large amount of pigment and its size can be reduced. Additionally, since the eyeliner solution can be stored in the tank as is, the amount of preservative can be reduced.

(Example) An example of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of an eyeliner according to an embodiment of the present invention, and FIG. 3 is a front view showing the eyeliner with a cap attached. In the figure, an eyeliner 10 includes a pen nib 11 whose tip is formed into a spindle shape using felt or the like made of a permeable material, a nib holder 12 holding this pen nib 11, and a rear end of this pen nib holder 12. a built-in flow rate adjustment unit 13 that adjusts the supply of eyeliner liquid to the pen tip;
A tank part 14 containing eyeliner liquid is connected to the rear end of the flow rate adjusting part, and the tank part 14 is connected to the rear end of the tank 14 and has a large number of annular narrow grooves 15a, and the other end communicates with the outside air. a gas-liquid separation mechanism 15,
A holder 16 that is fitted to the rear end of the pen nib holder 12 and surrounds the tank section 14 and the gas-liquid separation mechanism 15; and a cap 17 that is fitted to the holder 16.
It is composed of etc. Here, the pen tip 11 is
For example, it is preferable to use nylon fiber as the core material, which is secured with polyurethane resin or the like. Further, the porosity of the pen tip can be changed as appropriate depending on the concentration and viscosity of the eyeliner liquid.
The pen tip holder 12 holds the pen tip 11 with a tapered grip portion 12a, and a flow rate adjustment portion 13 is fitted at the rear end. As shown in FIGS. 4A and 4B, the flow rate adjustment section 13 is formed by drilling a spiral groove 13a in the outer circumference of a cylinder. Spiral groove 13
The width of a is appropriately determined depending on the concentration and viscosity of the eyeliner.

FIGS. 5A and 5B show other embodiments of the flow rate adjustment section. In the figure, the flow rate adjustment section 13' is
A plurality of grooves 13'b are formed in the outer circumference of the cylinder in the longitudinal direction. The width, number, etc. of the grooves 13'b are appropriately determined depending on the concentration and viscosity of the eyeliner liquid.

Further, the flow rate adjusting section may be made of a permeable material having a different porosity from that of the pen tip. With this configuration, it is possible to prevent eyeliner liquid from dripping from the pen tip. The tank part 14 is
It has a hollow cylindrical shape and contains eyeliner liquid. Further, the gas-liquid separation mechanism 15 maintained at the rear end of the tank portion 14 has an introduction hole 15b bored in the center and a plurality of annular narrow grooves 15a communicating with the introduction hole 15b via slits 15d. It has a cylinder 1 on the outer periphery.
5c is attached.

The tank portion 14 and the gas-liquid separation mechanism 15 are connected to the holder 1 fitted to the rear end of the pen nib holder 12 as described above.
6, and an air hole 18 is provided at the front end of the holder 16. Therefore, the tank portion 14 communicates with the outside air via the gas-liquid separation mechanism 15 and the air hole 18. The air hole 18 is closed by a portion of the cap 17 when the cap 17 is attached. The annular narrow grooves 15a provided in the gas-liquid separation mechanism 15 are narrowly spaced near the tank portion 14 and widen as they move away from the tank portion 14.
Note that the interval between the annular narrow grooves 15a can be changed as appropriate depending on the viscosity of the liquid stored in the tank portion 14.

Next, the operation of the eyeliner configured as above will be explained.

First, the eyeliner liquid E stored in the tank section 14 oozes out from the pen tip 11 with the cap 17 removed via the flow rate adjustment section 13 as appropriate. Pen nib 11
The amount of seepage from the eyeliner is determined by the viscosity of the eyeliner liquid E and the porosity of the core material used for the pen tip. Exchange air for the amount of eyeliner liquid E used is supplied through the air hole 18 and the gas-liquid separation mechanism 15.

Therefore, the eyeliner liquid can be smoothly supplied to the pen tip 11, so that it is possible to write darkly. Further, when the air in the tank section 14 expands due to heat, a mixture of air and liquid first enters the introduction hole 15b of the gas-liquid separation mechanism 15. Of the mixture of air and liquid that has entered,
The liquid passes through the slit 15d and accumulates in the annular groove 15a due to capillary action. At first, water accumulates from the side closer to the tank where the gap is narrower, and then gradually builds up in the side where the gap is wider. On the other hand, the air separated from the liquid is discharged to the outside through the adjustment hole 15e and the air hole 18. Therefore, the eyeliner liquid will not leak due to air expansion. In addition, the preservative contained in the eyeliner releases chlorine or ammonia upon exposure to air and sterilizes the eyeliner. Therefore, when the eyeliner liquid is stored as a liquid without being impregnated with batting or the like as in the present invention, a small amount of preservative is sufficient. If cotton is impregnated, a large amount of preservative is required because the area exposed to air is large. In addition, in the eyeliner according to the present invention, if the functional part consisting of the tank part 14 and the gas-liquid separation mechanism 15 is made elongated in the pen nib 11 and the pen nib holder, the holder 16 forming the appearance can be
Various designs can be used.

Further, the present invention is not limited to the above embodiments, and various design changes can be made based on the technical idea of the present invention.

(Effects of the Invention) As explained above in detail, the eyeliner according to the present invention allows the eyeliner liquid to be stored as a liquid without using any batting or the like, so that a small amount of preservative can prevent the growth of bacteria. can be prevented. Furthermore, storing the eyeliner in its liquid state can prevent the eyeliner from oxidizing since the contact area with air is small.

Furthermore, since the gas-liquid separation mechanism makes it possible to supply air and take out the expanded air, which was a problem when storing liquid as it is in the past, the eyeliner liquid does not fade or leak. Furthermore,
The flow rate adjustment section can prevent the eyeliner liquid from dripping.
