Description

Cosmetic kit for making custom cushions}

The present invention relates to a cosmetic kit comprising an airtight container comprising at least three or more supporting units carrying cosmetic compositions of the same color tone.

Since ordinary cosmetics have only a single color, the consumer must purchase at least two products with different colors. Consumers have a favorite color depending on preference, seasonality, or situation, but since multiple products must be purchased and used, economic expenditure is accompanied.

In addition, cosmetics of colors that are not frequently used have an excessively long storage time and use time, so they are easily etched away or left unattended, which is uneconomical. For this reason, attempts have been made to include multiple colors in a single product.

For example, Korean Patent Publication No. 2001-0046449 discloses a multicolored cosmetic product prepared by filling a liquid multicolored cosmetic product in a partition and separating and solidifying the partition. In this method, the borders of colors are clearly distinguished.

In addition, Korean Patent Publication No. 2006-0099792 discloses a method of implementing lipsticks of different colors in the form of marbling on one stick. Although these two colors of marbling lipsticks are not distinguished by compartments, they are different from the gradation in the form of marbling. However, this is limited to one color when using one product.

Therefore, there is a need for more research on cosmetics capable of realizing color according to the taste of the consumer.

The present inventors invented a cosmetic kit capable of producing a customized cushion suitable for the skin tone of a consumer by selecting the color and number of units on which the cosmetic composition is carried.

Accordingly, an object of the present invention is to provide a cosmetic kit comprising an airtight container comprising at least three or more supporting units carrying cosmetic compositions of the same color tone.

The present invention relates to a cosmetic kit comprising an airtight container comprising at least three or more loading units carrying cosmetic compositions of the same color tone.

Hereinafter, the present invention will be described in more detail.

One embodiment of the present invention relates to a cosmetic kit comprising an airtight container comprising at least three or more supporting units carrying cosmetic compositions of the same color tone.

The supporting unit may be a foamed urethane foam, but is not limited thereto.

The foamed urethane foam may have a reticulated structure. When the foamed urethane foam has a network structure, the cosmetic composition can be uniformly supported on the foam, and the loading rate is higher.

The density of the foamed urethane foam is 1.0 to 3.0 pcf (pounds per cubic feet), 1.0 to 2.9 pcf, 1.0 to 2.8 pcf, 1.0 to 2.7 pcf, 1.0 to 2.6 pcf, 1.0 to 2.5 pcf, 1.0 to 2.4 pcf, 1.0 to It may be 2.3 pcf, 1.0 to 2.2 pcf, 1.0 to 2.1 pcf, for example, 1.0 to 2.0 pcf. If the density of the foamed urethane foam is less than 1.0, it is difficult to impregnate effectively because the cosmetic composition is too much and the usability decreases, and when the density exceeds 3.0, there are insufficient pores to impregnate the contents.

The number of pores of the foamed urethane foam is 70 to 120 ppi, 70 to 115 ppi, 70 to 110 ppi, 70 to 105 ppi, 70 to 100 ppi, 70 to 95 ppi, 75 to 120 ppi, 75 to 115 ppi , 75 to 110 ppi, 75 to 105 ppi, 75 to 100 ppi, for example, 75 to 95 ppi. If the number of pores is less than 70 ppi, the elasticity of the foam falls, resulting in poor usability, and it is difficult to control the fluidity of the cosmetic composition. When the number of pores exceeds 120 ppi, durability may deteriorate when using and the usability of the contents is poor.

The foamed urethane foam may have a hardness of 10 to 70. If the hardness is less than 10, the cosmetic composition used in the pact type or the cosmetic composition by hand is emulsified in the foamed urethane foam, and when the hardness exceeds 70, the hardness is too hard, so the cosmetic composition does not come out easily to be.

The foamed urethane foam may have an open cell structure. When the foamed urethane foam is a closed cell, the form of an open cell is preferred because the bubbles are trapped in the urethane and do not impregnate the low-viscosity emulsifying contents.

The urethane foam is solidified in a state in which a polyurethane resin is foamed, and may be polyester polyol (ester polymer foam) and/or polyether polyol (ether polymer foam).

The polyether polyol foam has excellent hydrolysis resistance, excellent elasticity, and low cost, but has a weak oil resistance. On the other hand, the polyester polyol foam has the advantages of easy bubble adjustment, excellent abrasion resistance, chemical resistance, etc., but it is easy to cause hydrolysis and has a disadvantage of breaking when stored for a long time at a high temperature.

Therefore, the foamed urethane foam is not formed by simple mixing of polyether polyol and polyester polyol, but hybrid type copolymerization formed by a copolymerization reaction to form a chemical bond of an ether-ester between polyether polyol and polyester polyol. It can be a chain.

The volume of the supporting unit may be 20 to 50 cm ³ , respectively, but is not limited thereto.

The cosmetic composition may be a W/O (water in oil) or O/W (oil in water) type emulsifying or oil dispersion type cosmetic composition.

When the cosmetic composition is an emulsion cosmetic composition, the viscosity of the cosmetic composition is 5000 to 15000 cps (Centi Poise), 5000 to 14000 cps, 5000 to 13000 cps, 5000 to 12000 cps, 5000 to 11000 cps, 5000 to 10000 cps, 6000 to 15000 cps, 6000 to 14000 cps, 6000 to 13000 cps, 6000 to 12000 cps, 6000 to 11000 cps, 6000 to 10000 cps, 7000 to 15000 cps, 7000 to 14000 cps, 7000 to 13000 cps, 7000 to 12000 cps, It may be 7000 to 11000 cps, 7000 to 10000 cps, 8000 to 15000 cps, 8000 to 14000 cps, 8000 to 13000 cps, 8000 to 12000 cps, 8000 to 11000 cps, for example, 8000 to 10000 cps have. If the viscosity of the cosmetic composition is less than 5000 cps, it is difficult to impregnate the urethane foam with a uniform composition due to separation of the oil phase and the water phase immediately after the preparation of the emulsifier. The value falls.

The term airtight container of the present invention means a container having a sealing force to prevent air inflow from outside and to prevent loss due to evaporation of volatile substances into the inside.

If the airtight container has no sealing force, the outside air is introduced into the inside so that the drying and loss of contents can occur. It is a container with improved sealing ability to prevent lip cosmetics from being deteriorated or cured by external air by preventing external air from entering the container. There is a problem that the cosmetics are deteriorated due to the inflow of external air or the evaporation of internal moisture and volatile components in the case of cosmetics with internal gas, such as moisture compact, moisture cream, shadow, etc. due to poor airtightness. As the inflow of external air into the container, or the evaporation of internal moisture and volatile components is prevented, it is possible to use cosmetics while maintaining quality for a long time without deterioration.

The airtight container may further include an inner cap. The container forms a sealing ring on the outside of the rising piston so that the sealing ring is operated in a state in close contact with the inner periphery of the upper container, so that external air flowing in from the lower side of the rising piston contacts the lip cosmetic to deteriorate or cure the lip cosmetic. It has the effect of preventing being.

The airtight container may further include a partition.

In another embodiment of the present invention, the cosmetic key may include at least two or more airtight containers including at least three or more supporting units carrying cosmetic compositions of the same color tone.

The supporting units included in each of the airtight containers may be loaded with cosmetic compositions of different colors.

In another embodiment of the present invention, the cosmetic kit may further include one or more selected from the group consisting of a mix container, a pallet, and a common container.

The mix container may be for coloring a desired color tone after adding the selected supporting unit.

The mix container may be inclined bottom portion.

The diameter of the mix container may be 5.0 to 10.0 cm, 5.0 to 9.0 cm, 5.0 to 8.0 cm, 6.0 to 10.0 cm, 6.0 to 9.0 cm, and may be, for example, 6.0 to 8.0 cm. It does not work.

In another embodiment of the present invention, the cosmetic kit may further include a puff.

In another embodiment of the present invention, the cosmetic kit may further include tweezers.

In another embodiment of the present invention, the cosmetic kit may further include an applicator.

The applicator may be in the form of a brush, but is not limited thereto.
