Technical Field

The present invention relates to an impregnated material, a cosmetic containing the same, and a method for producing a cosmetic.

Background

In general, cosmetics are used for the purpose of making a user beautiful, and are classified into cosmetics including solid cosmetics and cosmetics including liquid (or gel) cosmetics having fluidity, depending on the form of the cosmetics.

Recently, many cosmetics have been developed which are used by impregnating an impregnating material with a liquid cosmetic material having fluidity, and a porous polyurethane sponge is generally used as the impregnating material.

The impregnation material has a problem that the pore size is large, and when pressure is applied to the impregnation material, the cosmetic material is excessively discharged, and the discharge amount of the cosmetic material is rapidly reduced as the number of times of use is increased.

In addition, since the conventional impregnated material has a flat surface, when a finger is placed on the puff and the impregnated material is dipped with the puff for use, there is a problem that the cosmetic sticks to the tip of the puff or sticks to the finger of the user over the puff.

In addition, the conventional impregnated material has similar cosmetic discharge performance in the central area and the peripheral area of the impregnated material, and thus has a problem that the possibility of the cosmetic being stuck to the end of the puff is high.

Further, the conventional impregnation material has a problem that the amount of the cosmetic material which is not used in the peripheral region and is discarded is large because the central region and the peripheral region of the impregnation material are impregnated with the similar amount of the cosmetic material.

Detailed Description

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the present invention, when it is determined that the gist of the present invention can be confused by a specific description of a related known structure or function, a detailed description thereof will be omitted.

Fig. 1 is a perspective view schematically showing an impregnation material according to an embodiment of the present invention, fig. 2 is a plan view of the impregnation material of fig. 1 as viewed from the upper side, fig. 3 is a plan view of the impregnation material of fig. 1 as viewed from the side, and fig. 4 is a cross-sectional view schematically showing the impregnation material taken along the line a-a' in the impregnation material of fig. 2.

For convenience of explanation, the "+ y" direction is defined as the upper side and the "-y" direction is defined as the lower side with reference to fig. 4.

Referring to fig. 1 to 4, an impregnation material 10 according to an embodiment of the present invention may include: a central region 100 capable of being impregnated with a cosmetic material; and a peripheral region 200 provided at the edge of the central region 100. Here, the central region 100 and the peripheral region 200 may be understood as objects (impregnated bodies) that are continuous with each other and are formed of the same material. The impregnation material 10 of the present embodiment may be provided by a material having elasticity that can be impregnated with a cosmetic material. For example, the impregnation material 10 may be provided by one of polyurethane, NBR (nitrile butadiene rubber), SBR (styrene butadiene rubber), NR (natural rubber), polyester, polyether, polyethylene, and polypropylene.

According to an embodiment of the present invention, the impregnation material 10 may be formed in a circular shape when viewed from the upper side (refer to fig. 2). Specifically, the central region 100 and the peripheral region 200 of the impregnating material 10 are concentric when viewed from above. More specifically, the central region 100 may be formed in a circular shape when viewed from the upper side, and the peripheral region 200 may be formed in a ring shape surrounding the central region 100. However, the idea of the present invention is not limited to this, and the impregnation material 10 may include a case formed by various shapes such as a quadrangle, a triangle, and the like when viewed from the upper side.

When the impregnation material 10 is viewed from the side (see fig. 3), the central region 100 of the impregnation material 10 may have a shape that is convex upward from the peripheral region 200. Specifically, when the impregnation material 10 is viewed from the side (see fig. 3), the surface of the central region 100 of the impregnation material 10 may have a circular arc (circular arc) shape, and the peripheral region 200 may have a rectangular shape protruding from the central region 100 below the central region 100.

In addition, a center M may be provided at the uppermost portion of the central region 100. The center M of the central region 100 is understood to be the portion of the impregnated material 10 that protrudes most upward. The discharge of the cosmetic material carried in the impregnated material 10 can most easily occur in the vicinity of the center M of the central region 100, which will be described in detail later.

The ratio of the height h1 of the central region 100 to the height h2 of the peripheral region 200 may be 4:1 to 1: 1. Preferably, the ratio of the height h1 of the central region 100 to the height h2 of the peripheral region 200 may be 3:1 to 1.5: 1. As described above, by having the height ratio, a sufficient amount of the cosmetic can be impregnated into the central region 100, and an optimal amount of the cosmetic can be discharged according to the depth at which the user presses the central region 100.

In addition, an angle β of a virtual straight line extending from a fulcrum at which the upper side of the peripheral region 200 and one end of the central region 100 (the edge 112 of the central region 100) meet and tangent to the upper side of the central region 100 may be 15 ° to 75 °. Preferably, the angle β may be 45 ° to 60 °. At this time, if the angle β is 15 ° or less, the height h1 of the central region 100 becomes small, and the amount of the cosmetic material that can be impregnated into the central region 100 may be small, and if the angle β is 75 ° or more, when the impregnation material 10 is pressed by a cosmetic tool (for example, a puff), there is a possibility that a problem of interference between the edge 112 of the central region 100 and the middle ring 30 described later may occur.

An angle α formed by a virtual straight line extending from a fulcrum at which the upper side surface of the peripheral region 200 and the one end portion of the central region 100 meet to the center M of the central region 100 may be 10 ° to 25 °. Preferably, the angle α may be 15 ° to 17 °.

According to an aspect of the present invention, the impregnation material 10 may be formed such that the density is different from each other in a plurality of regions.

Specifically, the central area 100 of the impregnation material 10 according to an embodiment of the present invention may include: a first layer 110 provided on the upper side; and a second layer 120 provided on the lower side of the first layer 110. In addition, the impregnation material 10 of the present embodiment may further optionally include a third layer 130 provided on the lower side of the second layer 120.

When the central area 100 of the present embodiment is composed of two layers (the first layer 110 and the second layer 120), the density of the first layer 110 can be provided to be greater than the density of the second layer 120, and when the central area 100 is composed of three layers (the first layer 110, the second layer 120, and the third layer 130), the density of the first layer 110 can be provided to be greater than the density of the third layer 130, and the density of the third layer 130 can be provided to be greater than the density of the second layer 120.

The relative density relationship of the first layer 110, the second layer 120, and the third layer 130 is specifically explained as follows.

It may be provided that the cells 101 forming the first layer 110 are relatively more dense than the cells 102 forming the second layer 120. In addition, it may be provided that the cells 103 forming the third layer 130 are relatively more dense than the cells 102 forming the second layer 120. In addition, it may be provided that the cells 101 forming the first layer 110 are relatively more dense than the cells 103 forming the third layer 130.

Here, the first layer 110, the second layer 120, and the third layer 130 may be understood as layers formed of the same material and continuous with each other. The cosmetic material impregnated in the first layer 110, the second layer 120, and the third layer 130 may continuously flow at the boundary therebetween.

In this embodiment, the cells 101 forming the first layer 110 are relatively more dense than the cells 102 forming the second layer 120, which is understood to mean that the second layer 120 can be impregnated with a greater amount of cosmetic than the first layer 110.

In addition, since the cells 101 forming the first layer 110 are relatively denser than the cells 102 forming the second layer 120, when an external force is applied, the cosmetics may be uniformly discharged to the outside of the first layer 110 through the first layer 110.

The cells 101 forming the first layer 110 of the central region 100 may be formed with first pores S1 that can be impregnated with the cosmetic, and the cells 102 forming the second layer 120 may be formed with second pores S2 that can be impregnated with the cosmetic. The cells 103 forming the third layer 130 may have third pores S3 into which the cosmetic material can be impregnated.

Since the volume occupied by the second air holes S2 is greater than the volume occupied by the first air holes S1, the second layer 120 can be impregnated with a relatively larger amount of the cosmetic material than the first layer 110. In addition, since the volume occupied by the second air holes S2 is greater than the volume occupied by the third air holes S3 per unit volume, the second layer 120 can be impregnated with relatively more cosmetic material per unit volume than the third layer 130.

That is, of the three layers (the first layer 110, the second layer 120, and the third layer 130), the second layer 120 may be impregnated with the largest amount of the cosmetic material, the third layer 130 may be impregnated with the second largest amount of the cosmetic material, and the first layer 110 may be impregnated with the third largest amount of the cosmetic material. The peripheral region 200 described later may be impregnated with a minimum amount of the cosmetic or no cosmetic.

In addition, the first air holes S1 may be distributed in a greater number per unit volume than the second air holes S2, and thus, when external pressure is applied, the cosmetic may be uniformly discharged from the first layer 110 to the outside.

In addition, the upper side (outer side) of the first layer 110 can be seen by the naked eye of the user. At this time, since the first pores S1 formed in the first layer 110 are smaller than the second pores S2 formed in the second layer 120, the appearance of the first layer 110 is smooth without pores when observed with naked eyes, and thus the appearance of the impregnated material 10 can be improved.

In addition, the impregnation material 10 according to an embodiment of the present invention may have a structure in which the cosmetic material is more easily discharged from the edge 112 of the central area 100 toward the center M of the central area 100.

Specifically, the first layer 110 may be provided from the edge 112 of the central region 100 toward the center M of the central region 100, the thinner the thickness of the first layer 110. At this time, the first layer 110 may be formed from the edge 112 of the central region 100 toward the center M of the central region 100, and the cells 101 forming the first layer 110 have the same density, or are not sufficiently dense.

For example, the thickness t2 of the first layer 110 on the edge 112 of the central region 100 may be 2.0mm to 4.5mm, and the thickness t1 of the first layer 110 at the center M of the central region 100 may be 0.01mm to 1.0 mm. It may be preferred that the thickness t2 of the first layer 110 on the edge 112 of the central region 100 is from 2.5mm to 3.5mm and that the thickness t1 of the first layer 110 at the center M of the central region 100 is from 0.05mm to 0.5 mm. It may be more preferred that the thickness t2 of the first layer 110 on the edge 112 of the central region 100 is 3.0mm and the thickness t1 of the first layer 110 is 0.2mm at the center M of the central region 100.

By having the thickness range of the first layer 110 as described above, the discharge amount of the cosmetic material on the center M of the central area 100 can be made larger than the discharge amount of the cosmetic material on the edge 112 of the central area 100. Thus, a user can apply a relatively greater amount of cosmetic material in the center of a cosmetic applicator (e.g., puff), thereby preventing the cosmetic material from spilling over the edge of the puff to the back, or from sticking to the user's hand.

However, the idea of the present invention is not limited thereto. It may be included that the thickness of the first layer 110 is formed to be the same, and the cells 101 forming the first layer 110 are formed to be insufficiently dense from the edge 112 of the central region 100 toward the center M of the central region 100. In other words, the cells 101 forming the first layer 110 may be densely packed from the center M of the central region 100 toward the edge 112 of the central region 100.

Additionally, the thickness t3 of the second layer 120 may be thicker and thicker from the edge 112 of the central region 100 toward the center M of the central region 100.

For example, the thickness t3 of the second layer 120 may be 0.001mm to 2.0mm at the edge 112 of the central region 100, and the thickness t3 of the second layer 120 may be 50mm to 120mm at the center M of the central region 100. It may be preferred that the thickness t3 of the second layer 120 be 0.03mm to 0.5mm at the edge 112 of the central region 100 and that the thickness t3 of the second layer 120 be 70mm to 100mm at the center M of the central region 100. More preferably, the thickness t3 of the second layer 120 is 0.2mm at the edge 112 of the central region 100 and the thickness t3 of the second layer 120 is 90mm at the center M of the central region 100.

As described above, by gradually increasing the thickness of the second layer 120 from the edge 112 of the central region 100 toward the center M of the central region 100, the outer shape of the impregnated material 10 can be formed such that the central region 100 is more convex than the peripheral region 200.

In this case, the user may easily touch the cosmetic tool (e.g., puff) at the center M of the central region 100, so that the cosmetic may be prevented from overflowing to the back side over the edge of the cosmetic tool or from being stuck on the user's hand.

In addition, it may be formed that the upper side of the second layer 120 is surrounded by the first layer 110, and the lower side of the second layer 120 is surrounded by the third layer 130. In this case, the cosmetic may be absorbed by 90% or more by the second layer 120 of the central region 100 and stored.

It may be that the third layer 130 is provided on the lower side of the second layer 120, and the thickness of the third layer 130 is provided to be constant. For example, the thickness of the third layer 130 may be 0.1mm to 4.5 mm. It may be preferable that the thickness of the third layer 130 is 0.5mm to 2.5 mm. It may be more preferable that the thickness of the third layer 130 is 2 mm.

In addition, the cell 101 forming the first layer 110, the cell 102 forming the second layer 120, and the cell 103 forming the third layer 130 may be provided in an open pore form. Specifically, the cells 101 forming the first layer 110, the cells 102 forming the second layer 120, and the cells 103 forming the third layer 130 may have a closed loop shape, and the respective cells 101, 102 are connected and a plurality of cells may form a mesh structure. The shape of each cell 101, 102, 103 may have a polygonal shape such as a triangle, a quadrangle, a pentagon, a hexagon, etc., and the cells 101, 102, 103 of the shape may be connected to form a mesh structure. The cells 101, 102, 103 are schematically shown in fig. 4, and each cell 101, 102, 103 may be irregularly formed including a curved portion.

The unit 101 forming the first layer 110, the unit 102 forming the second layer 120, and the unit 103 forming the third layer 130 may be formed discontinuously, may be formed discontinuously by breaking the units through a thermal compression process (compression and heating process) to be described later, or may be welded or contacted with each other. This will be described in detail later.

In addition, the impregnation material 10 of the present embodiment may be provided such that the peripheral region 200 is impregnated with a smaller amount of the cosmetic material than the central region 100, or the peripheral region 200 does not contain the impregnated cosmetic material.

In particular, it may be provided that the cells 104 forming the peripheral region 200 are relatively more dense than the cells 101, 102, 103 forming the central region 100. More specifically, the cells 104 forming the peripheral region 200 are relatively denser than the cells 101 forming the first layer 110, the cells 102 forming the second layer 120, and the cells 103 forming the third layer 130.

The fact that the cells 104 forming the peripheral region 200 are relatively denser than the cells 101, 102, 103 forming the central region 100 means that the amount of cosmetic that can be impregnated into the peripheral region 200 is less than the amount of cosmetic that can be impregnated into the central region 100, or that the amount of cosmetic that cannot be impregnated into the peripheral region 200 is not present.

The conventional impregnated material has a problem that the cosmetic material impregnated in the edge (peripheral area) cannot be completely used and thrown away, but the present embodiment provides a structure in which the peripheral area 200 does not contain the impregnated material or can be impregnated with a small amount of the cosmetic material, thereby having an advantage that the cosmetic material thrown away without being used can be reduced.

As described above, the impregnation material 10 of the present embodiment can be divided into a plurality of regions (for example, four regions of the first layer 110, the second layer 120, the third layer 130, and the peripheral region 200) having different densities from each other, and can be impregnated with the cosmetic materials in different amounts (based on the unit region) in the respective regions.

In this case, the conventional impregnation material (for example, a dome-shaped impregnation material) has an advantage only in that the user can easily dip the cosmetic material using a shape such as a puff, but on the contrary, the impregnation material 10 of the present embodiment can adjust the amount of the cosmetic material impregnated into the impregnation material 10 according to the density of each region, and thus has an advantage that waste of the cosmetic material can be saved and the cosmetic material can be effectively discharged from the center M of the impregnation material 10.

Fig. 5 is a view schematically showing a process of preparing the impregnated material 10 of fig. 1.

As shown in fig. 5 (a) to 5(c), the impregnated material 2 is thermally compression-deformed into the impregnated material 10 before deformation.

Fig. 5 (a) is a view schematically showing a state in which the pre-deformation impregnation material 2, which is a raw material of the impregnation material 10, is set in the lower mold 6, and the upper mold 5 is compressed and heated before the pre-deformation impregnation material 2 is heated.

Fig. 5 (b) is a view schematically showing the impregnated material 2 before being deformed by compressing and heating the impregnated material 2 by the upper mold 5, and immediately before the impregnated material 2 is molded into the impregnated material 10.

Fig. 5(c) schematically shows a state in which the impregnation material 2 is compressed and heated before deformation to form the impregnation material 10.

The process of preparing the impregnated material 10 will be described below with reference to fig. 5 (a) to 5 (c).

The cosmetic preparation method according to an embodiment of the present invention may include: a step of setting the impregnation material 2 before deformation in the lower mold 6; a step of forming the impregnated material 10 by pressurizing and heating the pre-deformed impregnated material 2 by the upper mold 5 and the lower mold 6 as the upper mold 5 moves downward, and thermally deforming and compressing the upper portion and the lower portion of the pre-deformed impregnated material 2; a step of injecting the cosmetic material into the container body 20 and inserting the impregnated material 10 into the container body 20 into which the cosmetic material has been injected; and a step of inserting the middle ring 30 into the container body 20 so as to cover the surrounding area.

To explain this more specifically, the impregnation material 2 before deformation may be set in the lower mold 6 (see fig. 5 (a)). At this time, when the upper mold 5 and the lower mold 6 compress the pre-deformation impregnation material 2, the temperature may be controlled to a predetermined temperature at which the pre-deformation impregnation material 2 is thermally deformed.

The lower surface of the upper mold 5 contacting the pre-deformation impregnating material 2 may be controlled to a temperature for thermally deforming the pre-deformation impregnating material 2. For example, the lower face of the upper mold 5 may have a temperature range of 100 ℃ to 500 ℃. Preferably, the lower surface of the upper mold 5 may have a temperature range of 200 ℃ to 250 ℃. More preferably, the lower surface of the upper mold 5 may have a temperature range of 220 ℃.

The lower mold 6 is controlled to be lower than the upper mold 5, and may be controlled to be a predetermined temperature for thermally deforming the pre-deformation impregnation material 2.

Specifically, the lower mold 6 may exhibit a temperature range of 150 ℃ to 199 ℃ while the upper mold 5 exhibits a temperature range of 200 ℃ to 250 ℃. Preferably, the lower mold 6 may be set to a temperature of 190 ℃ while the upper mold 5 is set to a temperature of 220 ℃.

As described above, the temperature of the upper mold 5 is controlled to be higher than the temperature of the lower mold 6, so that the thermal deformation of the upper side (first layer 110) of the impregnated body 10 can be made larger than the thermal deformation of the lower side (third layer 130) of the impregnated body 10. That is, the cells 101 forming the first layer 110 may be formed to be denser than the cells 103 forming the third layer 130.

Here, it can be understood that the first layer 110 is a region directly deformed by the compression and heat of the upper mold 5, the third layer 130 is a region directly deformed by the compression and heat of the lower mold 6, and the second layer 120 is a region indirectly deformed by the upper mold 5 and the lower mold 6. In addition, referring to fig. 4, it can be understood that the thickness of the second layer 120 indirectly affected by the upper mold 5 and the lower mold 6 becomes gradually smaller from the virtual straight line O-O ' crossing the central M portion to the virtual straight line F-F ', the virtual straight line G-G '. In addition, it can be understood that the region between the virtual straight line G-G 'and the virtual straight line H-H' is a portion subjected to the maximum compression and thermal deformation by the upper mold 5 and the lower mold 6.

The upper mold 5 and the lower mold 6 may be formed in a shape corresponding to the shape of the impregnation material 10. For example, the lower mold 6 may be formed in a concave cylindrical shape, and the lower surface of the upper mold 5 may be formed in a concave shape.

The impregnation material 2 and the impregnation material 10 before deformation may be provided by a material having elasticity and capable of impregnating the cosmetic material. For example, the impregnation material 2 and the impregnation material 10 before deformation may be provided by one of polyurethane, NBR, SBR, NR, polyester, polyether, polyethylene, and polypropylene.

The shape of the impregnated material 2 before deformation may be a cylindrical shape. However, the impregnation material 2 before deformation may be provided in various shapes such as a quadrangular prism, a triangular prism, and the like, depending on the shape of the impregnation material 10.

After the process of fig. 5 (a), the upper mold 5 and the lower mold 6 may press and heat the pre-deformation impregnation material 2 to thermally deform the pre-deformation impregnation material 2 (refer to fig. 5 (b)).

The impregnation material before deformation 2' shown in fig. 5 (b) shows a case where the impregnation material before deformation 2 is compressed and thermally deformed by the upper mold 5.

The upper mold 5 can compress and thermally deform the upper part of the pre-deformation impregnation material 2 by pressurizing and heating the upper part of the pre-deformation impregnation material 2, and the lower mold 6 can compress and thermally deform the lower part of the pre-deformation impregnation material 2 by pressurizing and heating the lower part of the pre-deformation impregnation material 2.

After the process of fig. 5 (b), the upper mold 5 and the lower mold 6 may press and heat the pre-deformed impregnation material 2, so that the pre-deformed impregnation material 2 is deformed into the impregnation material 10 (refer to fig. 5 (c)). Here, the impregnation material 10 to be produced is the impregnation material 10 illustrated in fig. 1 to 4.

The impregnation material 10 can be thermally deformed and compressed by the upper mold 5 and the lower mold 6, thereby forming the cross section of the impregnation material 10 as shown in fig. 4.

After the process (c) in fig. 5, the impregnated material 10 may be optionally further processed as needed. For example, after the process (c) in fig. 5, at least one of the upper surface and the lower surface of the impregnation material 10 may be engraved with a laser. In this case, a pattern desired by the user may be printed on the upper surface or the lower surface of the impregnated material 10 (specifically, the upper surface of the first layer 110), thereby improving the appearance of the impregnated material 10.

Then, the cosmetic material may be injected into the container body 20 described later, the impregnation material 10 may be inserted into the container body 20 into which the cosmetic material is injected, and the middle ring 30 described later may be coupled to the container body 20. In this case, the cosmetic material may be absorbed into the inside of the impregnated material 10 (the second layer 120) through at least a part of the lower side of the impregnated material 10 (specifically, the lower part of the third layer 130). More specifically, the cosmetic is absorbed by the second layer 120 through the third layer 130, and the cosmetic absorbed by the second layer 120 may be continuously transferred to the first layer 110.

In this case, a cosmetic material injection hole (not shown) may be selectively formed in at least a part of the impregnation material 10. For example, a plurality of cosmetic material injection holes (not shown) may be formed in the third layer 130. In this case, the cosmetic injection hole may be formed through the third layer 130, whereby the cosmetic may quickly pass through the third layer 130 and be easily absorbed by the second layer 120. Therefore, when the cosmetic material injection hole is formed in the third layer 130, the impregnation material 10 can absorb the cosmetic material in a short time.

Wherein the cosmetic injection hole may be formed to have a diameter greater than an average diameter of the third air holes S3 formed through the cells 103 forming the third layer 130. For example, the cosmetic injection hole may be formed to have a diameter of 0.5 to 3.0mm, and preferably, the cosmetic injection hole may be formed to have a diameter of 1.0 to 1.5 mm.

The cosmetic material of the present embodiment may include any known material that can be supported on an impregnation material. For example, the cosmetic may include a foundation, an ultraviolet blocking agent, and the like.

However, the method of absorbing the cosmetic material inside the impregnated material 10 after the impregnation material 10 is completed is not limited thereto. For example, the impregnation material 10 may be inserted into the container body 20, and then the cosmetic material may be injected through the upper portion of the impregnation material 10. In addition, it is understood that the peripheral region 200 is a portion that is more compressed and thermally deformed than the first layer 110 and the third layer 130.

The impregnated material 10 is obtained by compressing and thermally deforming the peripheral region 200, the first layer 110, the third layer 130, and the second layer 120 in this order.

The peripheral region 200 may be compressed and thermally deformed by 40% to 90% with respect to the pre-deformed impregnated material 2. Preferably, the peripheral region 200 may be compressed and thermally deformed by 70% to 85% with respect to the material 2 to be impregnated before deformation.

The first layer 110 may be compressed and thermally deformed by 1% to 80% with respect to the pre-deformed impregnated material 2. Preferably, the first layer 110 may be compressed and thermally deformed by 30% to 60% with respect to the pre-deformation impregnation material 2.

Specifically, the center M of the first layer 110 may be compressed and thermally deformed by 1% to 20% with respect to the pre-deformation impregnation material 2, the edge 112 of the first layer 110 may be compressed and thermally deformed by 50% to 80% with respect to the pre-deformation impregnation material 2, and the degree of compression and thermal deformation may be increased as the center M approaches the edge 112.

The second layer 120 may be compressed and thermally deformed by 1% to 20% with respect to the pre-deformation impregnation material 2. Preferably, the second layer 120 may be compressed and thermally deformed by 3% to 7% with respect to the pre-deformation impregnation material 2.

The third layer 130 may be compressed and thermally deformed by 1% to 50% with respect to the pre-deformed impregnation material 2. Preferably, the third layer 130 may be compressed and thermally deformed by 10% to 30% with respect to the material 2 to be impregnated before deformation. More preferably, the third layer 130 may be compressed and thermally deformed by 15% with respect to the material 2 before deformation.

In addition, the surrounding area 200 may form the fourth air holes S4 by forming the cells 104 of the surrounding area 200. In this case, the average size of the fourth pores S4 located in the peripheral region 200 may be 1% to 30% of the average pore size of the impregnation material 2 before deformation. Preferably, the average size of the fourth pores S4 located in the peripheral region 200 may be 5% to 20% of the average pore size of the impregnation material 2 before deformation.

At this time, it can be understood that the fourth pores S4 in the surrounding area 200 are the cells forming the pre-deformation impregnated material 2, and are compressed and thermally deformed, so that the pores of the pre-deformation impregnated material 2 disappear or become very small.

In addition, the first layer 110 may form the first air holes S1 through the cells 101 forming the first layer 110. At this time, the average size of the first air holes S1 located in the first layer 110 may be 20% to 90% of the impregnation material 2 before deformation. Preferably, the average size of the first air holes S1 located in the first layer 110 may be 30% to 60% of the impregnation material 2 before deformation.

In addition, the second layer 120 may form the second air holes S2 by forming the cells 102 of the second layer 120. In this case, the average size of the second pores S2 in the second layer 120 may be 80% to 97% of the impregnation material 2 before deformation.

In addition, the third layer 130 may form the third air holes S3 by forming the cells 103 of the third layer 130. In this case, the average size of the third pores S3 in the third layer 130 may be 70% to 80% of the impregnation material 2 before deformation.

Fig. 6 is a cross-sectional view schematically showing an impregnation material 10' according to still another embodiment of the present invention.

The impregnated material 10' according to the embodiment of fig. 6 is explained below. However, in this embodiment, compared with the impregnation material of the embodiment shown in fig. 1 to 4, there is a difference that the fixing portion 210 is further included on the periphery of the peripheral region 200', and therefore, the description will be given mainly by taking the difference, and the description and reference numerals of the above embodiment will be applied to the same portions.

The central region 100 of the impregnation material 10' according to still another embodiment of the present invention includes the first layer 110', the second layer 120', and the third layer 130', and the fixing part 210 may be further provided at the edge of the peripheral region 200 '.

The fixing part 210 may be formed at the periphery of the surrounding area 200', protruding toward the upper side of the surrounding area 200'.

Specifically, the fixing part 210 may include: a rising portion 212 extending from the peripheral region 200' toward an outer upper portion; and an extension portion 214 extending outward from the rising portion 212.

Wherein, the length c of the surrounding area 200', the length d of the rising part 212, and the length e of the extension part 214 may be provided to be the same. For example, it may be that the length c of the surrounding area 200', the length d of the rising portion 212, and the length e of the extending portion 214 are all provided to be 1.5 mm.

In addition, the height b of the fixing part 210 may be provided to be 1.5 to 2 times the height h2 of the surrounding area 200'. For example, it may be provided that the height h2 of the surrounding area 200' is 3.0mm and the height b of the fixing portion 210 is 5.5 mm.

As described above, by providing the fixing portion 210, the fixing portion 210 is fixed by the later-described middle ring 30, and thereby the impregnation material 10' can be firmly fixed to the later-described container body 20.

In addition, a surrounding area 200' where cosmetic does not pass or a trace amount exists is formed inside the fixing portion 210 (in a direction toward the center M), so that the cosmetic located in the second layer 120' can be prevented from being transferred to the fixing portion 210 by the surrounding area 200 '. Therefore, the fixing portion 210 may be impregnated with no or a very small amount of the cosmetic material.

Fig. 7 is a cross-sectional view schematically showing an impregnated material 10 "according to still another embodiment of the present invention, fig. 8 is a view schematically showing a method for producing the impregnated material 10" of fig. 7, and fig. 9 is a view schematically showing an impregnated material 2 "before deformation, which is a raw material of the impregnated material 10" of fig. 7.

The impregnation material 10 ″ according to the embodiment of fig. 8 is explained below with reference to fig. 8 to 10. However, in this embodiment, compared with the impregnation material of the embodiment of fig. 1 to 4, there are different points where the impregnation material 10 ″ is provided in a cylindrical shape instead of a convex shape, and therefore, the description will be mainly given of the different points, and the description and reference numerals of the above embodiment will be applied to the same parts.

The impregnation material 10 ″ according to still another embodiment of the present invention may include: a first layer 110 "provided on the upper side; a second layer 120 "provided on the underside of the first layer 110"; and a third layer 130 "provided on the underside of the second layer 120".

The units forming the first layer 110", the second layer 120", and the third layer 130 "of the present embodiment may be provided as the same as the units of the first layer 110, the second layer 120, and the third layer 130 of the above-described embodiments, and thus, detailed descriptions thereof are omitted.

The thickness of the first layer 110 "may be thicker and thicker from the center M of the central region 100 to the edges of the first layer 110".

In addition, the thickness of the second layer 120 "may be thinner from the center M of the central region 100 to the edges of the second layer 120".

In addition, the sum of the thicknesses of the first layer 110", the second layer 120", and the third layer 130 "may be provided to be the same throughout the entire region of the impregnated material 10". That is, the impregnation material 10 "is formed in a flat cylindrical shape, wherein the thickness of the center M of the first layer 110" can be provided thinner than the thickness of the edge of the first layer 110", so that the cosmetic impregnated in the impregnation material 10" can be easily discharged to the vicinity of the center M.

The impregnation material 10 ″ may be formed by pressing and heating the pre-deformation impregnation material 2' by the upper mold 5' and the lower mold 6 '.

The upper mold 5 'may be formed flat, and the lower portion of the upper mold 5' may be provided with a preset temperature to thermally deform the pre-deformation impregnation material 2 ″.

The impregnation material 2' may have a recessed groove 250 formed in the upper portion thereof before deformation. The pre-deformed impregnated material 2 ″ in the above shape can be heated and thermally deformed by the upper mold 5 'and the lower mold 6', thereby forming the flat impregnated material 10 ″.

Fig. 10 is a view schematically showing a case where one of the impregnation materials shown in fig. 1 and 6 is installed in the container body 20.

Referring to fig. 10, the impregnation material 10, 10' of the above embodiment may be provided in the container body 20.

Specifically, the cosmetic 1 may include: the impregnated materials 10, 10' of the above embodiments; and a container body 20 capable of containing the impregnation materials 10 and 10'.

The container body 20 may include: a housing 22 providing a space for containing the impregnation material 10, 10'; and a top cover 24 that can selectively open and close the housing 22.

In addition, a middle ring 30 capable of fixing the impregnation material 10, 10' may be provided inside the housing 22. Specifically, the middle ring 30 may include: an impregnation material fixing ring 32 capable of fixing the peripheral regions 200 and 200'; and a fixing ring extension 34 extending upward from the impregnation material fixing ring 32. Here, the fixing ring extension 34 may have a height lower than the center M which is the uppermost end of the impregnation material 10, 10'. In this case, the most protruding portions of the impregnation materials 10 and 10 'are provided lower than the upper end of the container body 20 and the upper end of the fixing ring extension 34, so that the impregnation materials 10, 10', and 10 ″ can be prevented from being contaminated even if the cosmetic 1 falls off by opening the top cover 24. However, the idea of the present invention is not limited thereto, and the center M of the central region 100, which is the uppermost end of the impregnation material 10, 10', 10 ″ may be provided to be the same height as the fixed ring extension 34 or to be provided at an upper side than the fixed ring extension 34. As described above, when at least a portion of the central region 100 is provided at the same height as the middle ring 30 or at an upper side compared to the middle ring 30, the user may apply the cosmetic near the center of the cosmetic tool (e.g., puff). Therefore, the cosmetic can be prevented from overflowing to the back of the cosmetic tool or sticking to the user's hand.

The action and effect of the impregnation material will be described below.

The central area 100 of the impregnation material 10 according to an embodiment of the present invention may include: a first layer 110 provided on the upper side; a second layer 120 provided on the lower side of the first layer 110; and a third layer 130 provided on the lower side of the second layer 120, the cells 101 forming the first layer 110 and the cells 103 forming the third layer 130 being provided relatively more densely than the cells 102 forming the second layer 120.

In this case, since the cells 101 forming the first layer 110 are relatively denser than the cells 102 forming the second layer 120, the cosmetics can be uniformly discharged to the outside of the first layer 110 through the first layer 110. In addition, the second layer 120 may be surrounded by the first layer 110 and the third layer 130 having a higher density than the second layer 120, and thus, most of the cosmetic may be absorbed by the second layer 120. In this case, the cosmetics may be protected by the first layer 110 and the third layer 130, so that evaporation or solidification of the cosmetics may be prevented.

In addition, it may be provided that the first layer 110 is thinned in thickness from the edge 112 of the central region 100 toward the center M of the central region 100. In this case, the impregnated material 10 can easily discharge the cosmetic material from the edge 112 of the central region 100 toward the center M of the central region 100.

At this time, the user may apply a relatively greater amount of cosmetic material to the center of the cosmetic tool (e.g., puff), so that the cosmetic material may be prevented from overflowing to the back side over the edge of the puff or from being stuck on the user's hand.

The thickness of the second layer 120 is gradually increased from the edge 112 of the central region 100 toward the center M of the central region 100, so that the outer shape of the impregnated material 10 can be formed in a shape in which the central region 100 is protruded from the peripheral region 200. In this case, the user may easily touch the cosmetic tool (e.g., puff) at the center M of the central region 100, so that the cosmetic may be prevented from overflowing to the back side over the edge of the cosmetic tool or from being stuck on the user's hand.

In addition, it may be provided that the cells 104 forming the peripheral region 200 are relatively more dense than the cells 101, 102, 103 forming the central region 100. In this case, the surrounding area 200 contains no makeup base or contains a small amount of makeup base, and therefore, there is an advantage that the amount of makeup base that is discarded without being used can be reduced.

Further, a cosmetic material injection hole (not shown) may be formed in the lower portion of the impregnation material 10. In this case, since the cosmetic material injection hole is formed in the third layer 130 region having the dense cells, the cosmetic material can be injected into the second layer 120 in a short time, and thus the time for injecting the cosmetic material into the impregnation material 10 can be shortened.

In addition, a third layer 130 having more dense cells than the second layer 120 may be provided at a lower portion of the second layer 120. In this case, the second layer 120 of the impregnated material 10 can be impregnated with the cosmetic material at the maximum. Accordingly, the user can use the cosmetic impregnated in the second layer 120 without remaining, so that the amount of the cosmetic thrown away after use can be reduced.

In addition, the impregnation material 10 'according to still another embodiment of the present invention may provide the fixing part 210 at the edge of the surrounding area 200'. As described above, by providing the fixing portion 210, the impregnation material 10' can be firmly fixed to the container body 20 by the fixing portion 210.
