An air hole 111 is formed in the main body 10. The air hole 111 may be formed as a single air hole and/or a continuous air hole. In the first embodiment, the closer to the application surface, the greater the number of air holes 111 per unit volume. That is, the closer to the application surface, the more the volume occupied by the pores 111 increases. In another embodiment, the size of the air hole 111 may gradually change with the thickness of the application surface.

3A to 3D, the cosmetic release in the cosmetic applicator according to the first embodiment described above will be described.

If the cosmetic is absorbed, the cosmetic is absorbed into the main body 10 as shown in FIG.

After the user absorbs the cosmetics into the main body 10, the cosmetic applicator 1 contacts the skin several times to release the cosmetics.

3B, 3C, and 3D show the release of the cosmetic when the user releases the cosmetic one time, two times, and three times. If the user releases cosmetics, the cosmetics on the main body 10 will decrease. At this time, the closer the cosmetic applicator 1 according to the first embodiment is to the application surface, the larger the volume of the pores 111, and therefore, the remaining cosmetics move to the application surface. That is, while moving in the direction of the larger pores 111 containing more cosmetics, the concentration distribution is increased toward the application surface.

As described above, in the cosmetic applicator 1 according to the first embodiment, according to the release action of the user, the cosmetic moves to the application surface. Thereby, the user can easily and sufficiently release the residual cosmetics, and the hygiene of the cosmetic applicator 1 can be maintained.

In the first embodiment described above, the distribution of the pores 111 functions as a moving structure that moves the low-viscosity cosmetics in the direction of the application surface.

According to the release action of the user, the concentration distribution of the cosmetics in the main body 10 can be very diversified. 4A to 4E show the cosmetics according to the thickness direction of the application surface from the opposite side to the third release action of the main body 10 from the first absorption of the cosmetic, that is, the thickness of the cosmetic according to the direction from A to B in FIG. 2 Graph of concentration distribution.

The concentration of the cosmetics in the main body 10 can be linearly changed as shown in FIGS. 4A to 4C. The concentration of the cosmetic on the application surface has a similar value as shown in Figure 4A and Figure 4B until the cosmetic is completely released, or it can be reduced with the number of releases as shown in Figure 4C. Fig. 4A shows the distribution of the cosmetics to the A side during the first absorption of the cosmetics. Figs. 4B and 4C show the distribution of the cosmetics from the application surface to a fixed height during the first absorption of the cosmetics.

The concentration of the cosmetics in the main body 10 can be changed into a curve as shown in FIG. 4D and FIG. 4E. If it is close to the application surface as shown in Figure 4D, the cosmetic concentration can converge to the maximum value, or the closer to the application surface as shown in Figure 4E, the more rapidly it increases.

In the distribution of various cosmetics in FIG. 4 as described above, the cosmetics move in the direction of the application surface according to the number of times the cosmetics are released. Therefore, the user can easily and sufficiently release the residual cosmetics and the hygiene of the cosmetic applicator 1 can be maintained.

Hereinafter, referring to FIGS. 5 to 9, the second embodiment to the sixth embodiment of the present invention will be described.

In the second embodiment shown in FIG. 5, the size of the air hole 111 increases toward the application surface. Therefore, with the release action of the user, the cosmetics move to the application surface with a larger size of the air hole 111.

In the second embodiment described above, the distribution of the pores 111 functions as a moving structure that moves the low-viscosity cosmetics in the direction of the application surface.

In another embodiment, the size and number of the air holes 111 are changed, and the closer to the application surface, the greater the volume occupied by the air holes 111.

In the third embodiment shown in FIG. 6, the main body 10 is divided into a first layer 11 and a second layer 12, and the air holes 111 occupy a larger volume in the overall thickness of the main body 10 toward the application surface.

In the fourth embodiment shown in FIG. 7, a cosmetic accommodating space 112 is formed inside the main body 10. The cosmetic accommodating space 112 is an empty space, and is a space distinguished from pores.

The cosmetic accommodating space 112 is located close to the lower part of the main body 10, that is, close to the application surface in the thickness of the main body 10. The absorbed cosmetics have cosmetic properties of coagulation with each other, and therefore gather in the cosmetic containing space 112. If the cosmetics are released, the remaining cosmetics will accumulate in the cosmetic containing space 112 close to the application surface. In this case, because the cosmetics have the characteristic of gathering together to form large droplets, they move in the direction of the cosmetics in the cosmetics accommodating space 112 that occupies a relatively large volume.

In this way, in the cosmetic applicator 1 according to the fourth embodiment, if the cosmetics are released from the cosmetic containing space 112, the concentration of the residual cosmetics will increase toward the application surface. In the fourth embodiment described above, the cosmetic storage space 112 formed adjacent to the application surface functions as a moving structure that moves the low-viscosity cosmetics in the direction of the application surface.

The volume of the cosmetic containment space 112 for improving the release characteristics should be larger than the surrounding pores. The volume of each cosmetic space 112 that exists independently can be 5 of the average volume of the pores. Times to 100 times, 10 times to 100 times, or 10 times to 1000 times, and may be 0.2 times to 10 times or 0.5 times to 100 times the volume of all the pores of the body 10. Or the total volume of each cosmetic accommodating space 112 may be 1/200 to 1/5 or 1/100 to 1/10 of the overall volume of the main body 10, or substantially the cosmetics may be 1/200 to 1/200 of the volume of the absorbent main body 10 1/5 or 1/100 to 1/10.

In another embodiment, the main body 10 is composed of a first layer at the upper part and a second layer at the lower part, and the cosmetic containing space 112 is surrounded by the first layer and the second layer. Specifically, a recessed mark may be formed on the upper part of the first layer located at the lower part, and the first layer and the second layer may be combined to provide a cosmetic storage space 112.

In this case, the materials of the first layer and the second layer may be the same or different. In particular, the first layer located on the upper part can be provided with a non-porous, non-absorbent material.

In another embodiment, the main body 10 has a structure with more than three layers, and the cosmetic containing space 112 may be provided in the lowermost layer (ie, the layer with the application surface).

In the fifth embodiment shown in FIG. 8, the closer the air hole 111 is to the application surface, the larger the volume occupied, so that a cosmetic accommodating space 112 is formed near the application surface. In the fifth embodiment, the distribution of pores 111 and the cosmetic accommodating space 112 formed adjacent to the application surface function as a moving structure that moves the low-viscosity cosmetics to the application surface.

In the sixth embodiment shown in FIG. 9, a cosmetic affinity layer 113 is formed on the application surface. That is, the closer to the application surface, the more the affinity of cosmetics increases.

The cosmetic affinity layer 113 can be obtained by additionally adding cosmetic affinity ingredients to the application surface of the main body 10 or performing surface treatment. In another embodiment, the cosmetic affinity ingredients are injected into the body 10, and the closer to the application surface, the higher the concentration of the cosmetic affinity ingredients Style manufacturing. In yet another embodiment, the cosmetic affinity layer 113 may be another layer made by coating or the like.

According to the released residual cosmetics, the application surface moves toward the application surface due to the high cosmetic affinity of the application surface.

In the sixth embodiment, the cosmetic affinity obtained by the cosmetic affinity layer 113 increases toward the application surface, and the increase in cosmetic affinity functions as a moving structure that moves the low-viscosity cosmetics toward the application surface.

It is not shown here, but in another embodiment, the application surface may be made of another film layer and the film layer is formed with a pump structure that releases cosmetics from the inside to the outside. In this case, the pump structure functions as a moving structure.

On the other hand, the moving structure described above should be understood to be limited to the area where the cosmetic applicator substantially absorbs and releases the cosmetic. For example, in the case of a cosmetic applicator with a second layer that does not absorb cosmetics at all and a first layer with an application surface, regardless of the pore structure of the second layer, if the first layer substantially absorbs and releases cosmetics The formation of the movable structure part falls within the scope of the present invention.

The above-mentioned embodiments are used as examples for explaining the present invention, and the present invention is not limited thereto. Those with common sense in the technical field to which the present invention belongs can implement various modifications according to the above-mentioned embodiments. Therefore, the technical protection scope of the present invention should be defined by the scope of the attached patent application.
