Description

Cosmetic puff and method for manufacturing the same {Cosmetic puff and the method thereof}

The present invention relates to a cosmetic puff, and more particularly, to a cosmetic puff used when applying a liquid cosmetic composition to a makeup area.

A representative example of a cosmetic applicator is a puff. The puff is used to make makeup while applying cosmetics such as powder or cake-like powder or twin cake to the human face. Recently, with the development of technology for commercializing paste or liquid cosmetics in a form that is easy to carry, research on puffs for applying liquid foundation to the skin has been steadily conducted.

When applying color makeup, a puff is mainly used as a cosmetic applicator, and recently, the terms wet puff and dry puff have been commonly used in the beauty industry. A wet puff is a cosmetic puff that is wetted with moisture such as toner and has the advantage of providing a sense of closeness and an immediate cooling sensation. However, when used in a flat puff that can be built into a compact type that is easy to carry (a cosmetic puff for cushion pact), there is a problem that the puff gets wet and wet, and the handle part gets wet, resulting in poor durability.

In order to solve this problem, wet polyurethane puffs mainly used in liquid foundation products generally have a three-layer structure composed of wet polyurethane/polyurethane sponge/artificial leather (polyurethane material).

However, such a three-layered puff does not transfer all of the cosmetics to the face when the contents are applied to the surface layer, and the puff absorbs excessively, penetrating into the sponge layer, which is the middle layer, and even the last artificial leather layer. there was a side In order to prevent this, there is a puff designed to prevent the contents from penetrating into the second layer, the sponge layer, by attaching a separate film between the first and second layers using an adhesive, but when attaching the film using a separate adhesive, the film There was a problem such as a defect problem such as wrinkling and a decrease in productivity. Furthermore, there was a problem that the film was not applied evenly, resulting in a rough surface of the puff and deterioration of the makeup effect during continuous use.

Therefore, the problem to be solved by the present invention is to provide a puff capable of preventing excessive absorption of a cosmetic composition through the puff.

The present invention is also intended to provide a method for manufacturing a puff that can improve productivity, reduce costs, and minimize the defect rate by reducing the process in the existing method.

The present invention is also intended to provide a new type of cosmetic puff that can economically use cosmetics by reducing the amount of cosmetic composition absorbed into the puff and a manufacturing method thereof.

However, those skilled in the art will understand that the present invention is not limited to the embodiments described herein and may be embodied in other forms through the embodiments described later.

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

One embodiment of the present invention may provide a new type of cosmetic puff capable of preventing excessive absorption of contents through the surface layer, which may occur when a liquid cosmetic composition is applied 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 formed by spraying a coating liquid.

Existing cosmetic puffs for applying liquid cosmetics are excessively absorbed into the puff when the contents are applied to the surface layer, and penetrate into the sponge layer, which is the middle layer, and even the last outer layer. . In order to solve this, there was a structure having a coating layer that serves as a film by applying an adhesive between the surface layer and the sponge layer to adhere the film, or by applying an adhesive. However, the present invention connects the surface layer and the sponge layer by spraying the adhesive in a spray jet method without attaching a separate film or applying an adhesive liquid, thereby preventing the contents from penetrating into the sponge layer during makeup.

<Manufacture of cosmetic puff>

1. Example - Cosmetic puff prepared by spraying adhesive

Materials were prepared to manufacture a cosmetic puff laminated with wet urethane/sponge/artificial leather layers.

The wet urethane and sponge were bonded using a vinyl acetate copolymer adhesive by spraying.

2. Comparative Example - Cosmetic puff manufactured by liquid coating method

Materials for preparing a cosmetic puff composed of wet urethane/coating layer/sponge/artificial leather layer were prepared for comparison with the cosmetic puff prepared by spraying the adhesive.

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

<result>

1. Overall comparison result

As a result of comparing the cosmetic puffs prepared in the above Examples and Comparative Examples, the following results were obtained.

Comparative example (application type) Example (spray injection method) work efficiency lowness
(Drying time is relatively long) height
(Drying time is relatively short) thickness thick and relatively inhomogeneous uniform and thin Feeling of use when making puff Softness is reduced due to thick coating layer
(stiffness) Similar to softness with no coating layer coating liquid A lot of coating solution used Less use of coating liquid drying temperature Requires high temperature environment (drying by temperature) Can be volatilized and dried in a room temperature environment

As can be seen in Table 1, the puff made by the method of Comparative Example has a thick coating layer, resulting in a poor feeling of use. It is thought that this is because the amount of the coating liquid absorbed into the sponge layer and the surface layer increased, but is not necessarily limited to this.

On the other hand, in the case of Comparative Example, a high-temperature drying environment is required to dry the coating solution. However, the cosmetic puff of the present invention uses a spray spraying method, so that the adhesive can be dried without a high temperature environment, so the defect rate is low.

2. Comparison of barrier layer thickness

Using an image analyzer i Megascope from SOMETECH, the thickness of the barrier layer was compared. A 60x magnification/160x magnification/1000x magnification/1700x magnification lens was used.

(1) Check the cross-section of the liquid-coated puff

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

As a result of cross-section magnification of the surface coated with normal application and the surface with spray coating by 60 times, the surface coated with the liquid application method has an uneven surface and the thickness can be confirmed in the photograph, while the spray coating is magnified 60 times. Thus, the thickness could not be confirmed.

Figure 4 is a further enlarged view of the surface on which the coating liquid was applied, and it was confirmed that the coating liquid was lumpy and agglomerated.

5 is a photograph magnified 160 times of the liquid-coated surface, and when treated with the liquid-coated method, the drying speed was slow while processing, so that the coating layer was absorbed a lot into the sponge layer, and it was confirmed that the thickness was not constant.

The thickness showed a distribution from 500㎛ to about 1mm, and it was confirmed that the thickness was thick and not uniform.

(2) Check the thickness of the sprayed surface

The adhesive was sprayed onto the sponge layer. 6 shows the results of confirming the sprayed surface by magnifying 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.
