Description

Cosmetic puff

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic puff, and more particularly, to a cosmetic puff which improves a feeling of use by controlling the amount of contents absorbed in the puff.

A typical example of the applicator for cosmetics is a puff, which is used to put on cosmetics such as powder or cake powder or twin cake, and apply it to the face area of the human body. BACKGROUND ART [0002] In recent years, as a technique for commercializing cosmetics having fluidity of paste or liquid type into a portable form has been developed, studies on puffs for applying a fluid foundation or the like to skin have been steadily conducted.

As shown in Fig. 1, the cosmetic puff is generally composed of a three-layer structure composed of a skin-contact layer, an intermediate layer having a cushioning feel such as a sponge, and an upper layer for preventing the appearance of cosmetics on the hand. Each layer is adhered with an adhesive or the like.

The intermediate layer is mainly made of a material such as a sponge to provide a cushioning feeling, so that the cosmetic material in the skin-contacting layer penetrates into the intermediate layer and remains in the intermediate layer. In this case, waste of the contents occurs, and propagation of bacteria occurs, thereby causing skin trouble of the user. In particular, when a cosmetic composition having fluidity such as a liquid or a gel is used, the puff becomes damp due to the moisture of the excess cosmetic material remaining inside the sponge, which may cause discomfort.

In order to prevent this, when an adhesive layer is provided between the skin contact layer and the intermediate layer so as not to allow moisture to permeate, the content of the liquid cosmetic puff, which is discharged after a certain amount of the liquid cosmetic composition is drained, There may be a problem that the cosmetic effect is insufficient.

Accordingly, a problem to be solved by the present invention is to provide a cosmetic puff which provides excellent cosmetic effects by controlling the absorption amount of a cosmetic composition having moisture.

The present invention also provides a cosmetic puff capable of providing excellent dripping on the skin.

The present invention also aims to provide a cosmetic puff that can prevent excessive absorption of the contents into the cosmetic puff.

In order to solve the above problems, the present invention provides a cosmetic puff which can easily adjust the absorption amount of a cosmetic composition. Preferably, the cosmetic puff is a cosmetic puff for applying the cosmetic composition to the skin, and in one embodiment, the cosmetic composition may be provided in the form of a liquid cosmetic composition.

In the case of cosmetics which are generally called cushion products in the industry and which are impregnated with a liquid cosmetic composition into an impregnated member and applied to the skin, a desired cosmetic effect can not be expected with ordinary cosmetic puffs. Respectively.

The inventors of the present invention seek to solve the problem that when the cosmetic composition, particularly the liquid cosmetic composition, is applied to the skin, the cosmetic effect is excellent but the content is absorbed excessively into the puff.

Specifically, in the industry, there has been an effort to recognize and solve the problem that the content of the liquid cosmetic composition is excessively absorbed into the puff, but at the same time, there is a problem that the absorption of the content by puff is blocked, .

Accordingly, the inventors of the present invention have completed the present invention in order to recognize and solve the above problems for the first time.

The present invention provides a cosmetic puff for applying a cosmetic composition to skin, wherein the cosmetic puff is provided with two or more sponge layers, and the sponge layer is laminated with a film layer interposed therebetween .

Preferably, the sponge layer may have a two-layer structure.

The material of the sponge layer is not particularly limited and may be selected from the group consisting of natural rubber (NR), polyethylene, ethylene-vinyl acetate butyl rubber (EVA), latex, styrene-isoprene-styrene (SIS), styrene- (SBR), nitrobutadiene rubber (NBR), nitrile butadiene rubber (BR), non-latex, styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA) and hydrophilic polyurethane May be selected. Preferably, the material of the sponge layer may be a porous structure having elasticity and smooth movement of the contents, and a hydrophilic polyurethane sponge may be used. The hydrophilic polyurethane sponge may be an ether-based polyurethane or an ester-based polyurethane, or a hydrocarbon-based polyurethane or the like may be used. The range of hardness is Asker F type hardness meter, which can range from 10 to 90 when sponge is measured.

In one embodiment, the cosmetic puff may comprise a film layer between a sponge layer of a polyurethane material and a sponge layer of a polyurethane material.

In another embodiment, a film layer may be provided between the sponge layer of a polyurethane material and the sponge layer of an NBR material.

The material of the film layer may be any one or more water repellent materials selected from the group consisting of silicone resin and fluorine resin, polyurethane, synthetic leather and rubber, or a mixture thereof. . Preferably, the material of the film layer may be polyurethane. The polyurethane may be easily adhered to the upper end portion and the lower end portion of the puff.

In another embodiment of the present invention, the cosmetic puff includes two sponge layers of the same or different materials, the two sponge layers are laminated with a film layer therebetween, and the two sponge layers And a layer of wet polyurethane on the opposite side of the face to which the film layers are connected, respectively.

In a specific embodiment, the cosmetic puff of the present invention (preferably a liquid cosmetic composition cosmetic puff) comprises (i) a wet polyurethane layer applied to the skin with a cosmetic composition buried thereon, (ii) (Iii) a film layer connected to one surface of the sponge layer, (iv) a sponge layer connected to the film layer, and (v) an outer skin layer connected to the sponge layer .

The wet polyurethane layer may also be referred to as a ruby cell layer.

The wet polyurethane layer is a porous wet urethane and is a urethane made of a dense, soft material. The above-mentioned wet polyurethane can minimize the amount of cosmetics to be wasted because the amount of the cosmetic material permeated into the inside is small, and thus it is generally used in the industry for application of the liquid cosmetic composition. For example, the Techno Porous fabric of Fushimi Pharmaceutical may be applied.

A sponge layer may be provided on the opposite side of the surface of the wet polyurethane that contacts the skin.

The sponge layer may have a porous structure to facilitate movement of the cosmetic composition between the wet polyurethane and the sponge layer.

The sponge layer of the cosmetic puff may have a thickness of 2 to 20 mm and preferably a thickness of 3 to 9 mm in terms of the absorbency of contents and the feeling of elasticity in use.

The sponge layer and the wet polyurethane may be adhered to each other using a separate adhesive or may not be adhered to each other. Preferably, a separate adhesive may not be applied. When an adhesive is used, a permeable adhesive capable of transmitting the cosmetic composition through the wet polyurethane layer and the sponge layer can be used.

A film layer can be connected to the sponge layer and is formed on the opposite side of the wet polyurethane layer.

The absorbed cosmetic composition through the wet polyurethane layer can move through the sponge layer and the contents can be blocked further by the film layer.

When the film layer is located between the sponge layer and the polyurethane layer, the absorption of the cosmetic material can be blocked to prevent waste of the cosmetic material. However, there is a problem that the amount of the cosmetic composition is small and the effect of the cosmetic effect is insufficient Respectively.

The film layer is preferably formed on the sponge layer (this reference is based on when the wet polyurethane layer is placed on the bottom).

The cosmetic puff further comprises a new sponge layer distinct from the sponge layer associated with the wet polyurethane layer.

The new sponge layer may be referred to below as a second sponge layer.

The second sponge layer can impart a cushioning feeling of the puff and can provide an improved feeling of use. By the provision of the second sponge layer, the pressure transferred from the hand can be dispersed to enable uniform application of the cosmetic composition and to improve the elasticity and adhesion.

Two sponge layers can be combined with the film layer. The two sponge layers of the cosmetic puff may be made of different materials, or the same material may be used. When different materials are used, it is preferable that the pore size of the sponge layer connected to the wet polyurethane layer is larger.

Preferably, the sponge layer used in the puff of the present invention may be a polyurethane sponge.

The cosmetic puff of the present invention may be provided with an outer skin layer which can prevent the contents from being handed and attach the handle. The outer skin layer may preferably use artificial leather, and more preferably, artificial leather of polyurethane material can be used. For example, artificial leather, known under the trade name Jonas, can be used in the industry.

The cosmetic puff of the present invention can be sealed and attached to the edges. The sealing can be used in any industry as long as it is used for sealing puffs. Any method can be used without limitation, and sealing or hot melt using an adhesive can be applied and bonded, and ultrasonic waves or high frequency sealing can be used.

The form of the cosmetic puff of the present invention is not particularly limited, and may have various forms depending on the form of the cosmetic composition container such as a round shape, an elliptical shape, and the use purpose.

The cosmetic puff of the present invention can be used without particular limitation in the formulation of the cosmetic composition, but can be preferably used for applying the liquid cosmetic composition.

As used herein, the liquid cosmetic composition refers to a liquid type cosmetic composition, and any type of liquid formulation can be used as long as it is a fluid formulation. For example, a liquid foundation, a liquid concealer, a makeup base, a sunscreen, a highlighter, and the like.

The present invention provides a new type of cosmetic puff capable of optimizing the absorption amount of the cosmetic composition, and preferably provides a liquid cosmetic puff.

It is possible to provide an excellent cosmetic effect while preventing excessive absorption of the contents.

In order to solve the problem of excessively absorbing the cosmetic composition into the puff, there has been a problem that the cosmetic effect is insufficient due to the excessive absorption of the cosmetic composition. However, the present invention solves this problem and absorbs an appropriate amount of puff, While providing an increased cooling sensation to the skin.

The embodiments of the present invention are provided by way of example to facilitate a specific understanding of the present invention.

[ Example ]

A cosmetic puff for application of a liquid cosmetic composition was prepared.

Two layers of sponge layers were used, and a polyurethane sponge of the same material was used for each sponge layer.

The sponge layer was made to be connected to a film layer made of polyurethane.

A ruby cell (1.5T) layer was attached to one side of the sponge layer to produce a cosmetic puff.

[ Comparative Example . Three  rescue Puff  Produce]

A triple structure puff having a jonar, a urethane sponge, and a ruby cell (1.5T / 2.5T) layer was prepared.

Experimental Example  One. Coverage  compare

To each new puff of Example and Comparative Example, 1 g of a liquid foundation was applied and uniformly photographed on paper to compare its covering force and its pattern.

As can be seen from FIG. 3, in the case of a triple structure puff, it is seen that the excess amount of the contents is so small that the amount of the puff is small. In the case of the puff of the embodiment, an appropriate amount was discharged to obtain a cosmetic effect. Excellent results were also obtained in terms of coverage. These results are shown in Fig.

Experimental Example  2. Used 9 times On puff  Again The contents (1.0g)  Compared when shot uniformly after application

Referring to FIG. 4, in the case of triple puff, a lot of liquid foundation was absorbed, and it was confirmed that the covering force fell after 15 times.

In the case of the embodiment, since the puff itself absorbs an appropriate amount of contents, a uniform covering force can be provided, and an excellent moisture feeling can be transmitted to the skin.

These results are thought to be obtained as a result of the film layer positioned between the urethane sponge layers.

[ Three  rescue Puff and  compare]

The results of comparing the puffs of the example and the comparative example are shown in Fig.

As can be seen from FIG. 5, the cosmetic composition could be absorbed only up to the film layer, and the amount of the cosmetic composition remaining on the puff after application of the same amount of content was measured, .

On the other hand, as a result of manufacturing the puff by moving the position of the film layer between the sponge layer and the wet urethane layer, the amount of the cosmetic material to be absorbed was so small that the cosmetic effect was somewhat poor.
