BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following description of preferred embodiments with reference to the accompanying drawings. However, it will be understood by those skilled in the art that the present invention may be embodied in other forms without departing from the scope of the present invention.

The present invention provides a cosmetic puff for applying a liquid cosmetic composition.

One embodiment of the present invention can provide a new type of cosmetic puff that can prevent excessive absorption of the contents through the surface layer, which can occur when applying the liquid cosmetic composition to the skin.

The cosmetic puff of the present invention includes a surface layer and a sponge layer, and the surface layer and the sponge layer are connected by a barrier layer that can be formed by spraying the coating liquid.

Cosmetic puffs for applying cosmetic puffs for application of liquid cosmetics which are conventionally used have a side in which the cosmetic material is absorbed excessively in the puff when the contents are applied to the surface layer so that the sponge layer which is an intermediate layer penetrates even to the final skin layer and becomes wet when used and wastes contents . To solve this problem, there is a structure having a coating layer which acts as a film by applying an adhesive between a surface layer and a sponge layer to adhere the film or applying an adhesive. However, according to the present invention, the surface layer and the sponge layer are connected by spraying the adhesive in a spray-spraying manner without adhering a separate film and without applying an adhesive solution, thereby preventing penetration of contents into the sponge layer during makeup.

Wherein the surface layer of the cosmetic puff is permeable to water contained in the cosmetic composition or the cosmetic composition, and the cosmetic composition is transferred to the skin through the surface layer, so that the surface layer is in contact with the skin and the surface layer is connected to the sponge layer by the barrier layer .

The present invention provides a cosmetic puff for applying a liquid cosmetic composition, comprising a surface layer, a barrier layer formed on the surface layer, a sponge layer laminated on the barrier layer, and a shell connected to the sponge layer.

≪ Preparation of cosmetic puff >

1. Example - A cosmetic puff made by spraying an adhesive with a spray

A material was prepared to make a cosmetic puff layered with a wet urethane / sponge / artificial leather layer.

The wet urethane and sponge were bonded using a spray spray of a vinyl acetate copolymer adhesive.

2. Comparative Example - A cosmetic puff manufactured by a liquid coating method

For comparison with cosmetic puffs made by spraying the adhesive, a material for making cosmetic puffs composed of a wet urethane / coating layer / sponge / artificial leather layer was prepared.

The coating layer was prepared by applying an adhesive in a liquid state.

<Result>

1. Overall comparison result

The results of the comparison of the cosmetic puffs prepared by the above Examples and Comparative Examples were as follows.

Comparative Example (Coating type) Example (Spray spraying method) Work efficiency lowness
(Drying time relatively steady) height
(Relatively less drying time) thickness Thick and relatively uneven Uniform and thin thickness Feeling when making puff Thick coating layer reduces softness
(Stiffness) Smoothness similar to no coating Coating liquid Heavy use of coating solution Less use of coating liquid Drying temperature High temperature environment required (drying by temperature) Can be volatilized and dried in a room temperature environment

As can be seen from the above Table 1, the puff made by the method of the comparative example has a thick coating layer, resulting in poor feeling of use. This is because the amount of the coating liquid absorbed into the sponge layer and the surface layer is increased, but it is not necessarily construed as being limited thereto.

On the other hand, in the case of the comparative example, in order to dry the coating liquid, a high-temperature drying environment is required. In this case, a phenomenon that the sponge layer and the surface layer are twisted by heat was observed. However, since the cosmetic puff of the present invention uses a spraying method, the adhesive can be dried without a high temperature environment, and the defective rate is low.

2. Comparison of barrier layer thickness

The blocking layer thickness was compared using an image analyzer i Megascope from SOMETECH. 60 magnification / 160 magnification / 1000 magnification / 1700 magnification lens was used.

(1) Identification of cross section of liquid coated puff

FIG. 2 shows a coating method of a liquid coating method, and FIG. 3 shows a state in which a surface layer and a sponge layer are combined by spraying.

As a result, it was confirmed that the surface coated with the liquid coating method was not uniform in surface and the thickness could be confirmed on the photograph, while the spray coating was 60 times larger The thickness feeling could not be confirmed.

FIG. 4 shows a further enlarged view of the surface to which the coating liquid is applied, and it is confirmed that the coating liquid is agglomerated and agglomerated.

FIG. 5 is a photograph showing a liquid-coated surface 160 times magnified. When the coating was performed by the liquid coating method, it was confirmed that the coating layer was absorbed much into the sponge layer due to a slow drying rate and the thickness thereof was not constant.

The thicknesses were ranged from 500 μm to 1 mm, and it was confirmed that the thickness was thick and non-uniform.

(2) Check the thickness of the sprayed surface

An adhesive was sprayed onto the sponge layer. FIG. 6 shows results obtained by enlarging the sprayed surfaces by 1,000 times and 1,700 times, respectively.

As a result, it was confirmed that the thickness was 10 to 30 μm, and a relatively uniform thickness distribution was confirmed.
