Description

Cosmetic container including application sponge

Technical Field

The present invention relates to a container for a cosmetic composition, which comprises a sponge for controlling the discharge of the cosmetic composition and a sponge for applying the cosmetic composition.

Background Art

Typically, cosmetic compositions are applied by hand or using an applicator such as a sponge or brush. Using an applicator minimizes contamination of the hands, and the cosmetic composition can be applied more evenly than with the hands. In the past, a separate applicator, separate from the container containing the cosmetic composition, was used. However, this method has the following drawbacks: there is a concern about losing the applicator, the applicator can easily become contaminated, and the applicator is inconvenient to use. For these reasons, an integrated container has been developed in which an applicator is attached to the container of the cosmetic composition. However, this integrated container has the problem that the cosmetic composition is difficult to discharge due to the attachment of the applicator. To address this problem, the inventors of the present invention have developed an integrated container for a cosmetic composition equipped with an applicator, which allows for easy discharge of the cosmetic composition and also allows for even application of the cosmetic composition.

DETAILED DESCRIPTION

In this specification, the term "sponge" refers to a sponge-like material made of rubber, fiber, or resin that can be impregnated with, expelled from, and applied to a cosmetic composition. In this specification, the term "foam" refers to a material made of, for example, cured foam rubber, vinyl resin, or polyurethane. In this specification, the term "impregnation" refers to the ability to contain and retain a substance or ingredient, and the term "spreadability" refers to the ability to gently and evenly apply a substance or composition to the skin.

In order to evenly apply a cosmetic composition using an applicator such as a sponge without causing smearing or clumping, smaller pore sizes provide better application. However, cosmetic compositions with relatively high viscosity tend to have difficulty discharging through sponges with excessively small pore sizes. Therefore, there is a need for a container for a cosmetic composition equipped with an applicator that can simultaneously provide easy and proper discharge and even application of the cosmetic composition.

Hereinafter, the present invention will be described in detail.

One aspect of the present invention provides a container 100 for a cosmetic composition, the container comprising: a sponge 10 for controlling discharge of the cosmetic composition; and a sponge 20 for applying the cosmetic composition, the sponge 20 surrounding the sponge for controlling discharge of the cosmetic composition.

In one aspect of the present invention, a sponge for controlling the discharge of a cosmetic composition or a sponge for applying a cosmetic composition is characterized by having at least one of a curved surface and a flat surface. A sponge having at least one of a curved surface and a flat surface may be formed with a curved surface, a flat surface, or both. In particular, a sponge having at least one of a curved surface and a flat surface may have both curved and flat surfaces. A sponge having both curved and flat surfaces may have both spherical and plate-like portions. A sponge having at least one of a curved surface and a flat surface may have at least one shape selected from, but not limited to, a hemispherical shape, a semi-elliptical shape, a bell shape, a disc shape, a cylindrical shape, a star-shaped pillar shape, a triangular pillar shape, a square pillar shape, a cube shape, a tetrahedron shape, and a pyramid shape. In particular, the sponge may have a cylindrical shape ( FIG. 1 ).

In one aspect of the present invention, a sponge for controlling the discharge of a cosmetic composition serves the following functions: impregnating the cosmetic composition and supplying the cosmetic composition to the sponge used to apply the cosmetic composition, facilitating discharge. Specifically, in the present invention, the sponge for controlling the discharge of the cosmetic composition can control the amount of irregularly discharged contents (the cosmetic composition). In the present invention, the contents are discharged through a discharge hole in a bean-sized amount, and the amount discharged can vary depending on the viscosity of the contents and the size of the discharge hole. The number of sponges for controlling the discharge of the cosmetic composition can be one, two, or more, and the location of the sponges is not particularly limited. The holes in the sponge for controlling the discharge of the cosmetic composition can be air-permeable to prevent pressure from forming inside the container.

In one aspect of the present invention, a sponge for applying a cosmetic composition serves to evenly and gently apply the cosmetic composition supplied by the sponge to the skin, which is used to control the discharge of the cosmetic composition. Specifically, in the present invention, the sponge for applying a cosmetic composition serves as a makeup tool that can evenly and quickly achieve a desired makeup look. Because the cosmetic composition must be applied smoothly without marks, lines, or blotches, the sponge for applying the cosmetic composition may have micropores. Furthermore, because the sponge for applying the cosmetic composition directly contacts the skin, the sponge may be soft and provide a cushioning effect.

In one aspect of the present invention, the sponge may include a sponge made of fiber, specifically, including at least one material selected from cotton, acrylic resin, polyamide, nylon, polyester, silk and rayon. In another aspect of the present invention, the sponge may include a sponge made of nonwoven fabric.

In one aspect of the present invention, the sponge may include a foam. In one aspect of the present invention, the sponge may include a foam made from at least one material selected from acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), natural rubber (NR), polyvinyl chloride, polyethylene, ethylene-vinyl acetate copolymer (EVA), latex, silicone, styrene-isoprene-styrene copolymer (SIS), styrene-ethylene-butylene-styrene copolymer (SEBS), polyvinyl alcohol (PVA), nitrile rubber, butyl rubber, chloroprene rubber (chloroprene rubber), polyolefin, polyurethane, and a mixture of ether-based polyurethane and ester-based polyurethane. In another aspect of the present invention, the silicone foam may include a foam made from a silicone-based elastomer.

Polyurethanes can be obtained by reacting a high molecular weight polyol or a chain extender polyol with a polyisocyanate compound. The higher molecular weight polyol may be: 1) a polyether polyol, such as polypropylene glycol or polybutylene glycol; 2) a polyester polyol, such as adipate polyol or polycaprolactone polyol; 3) a polycarbonate polyol; or 4) a polyolefin polyol. The chain extender polyol may be ethylene glycol, 1,4-butanediol, 1,6-hexanediol, 1,5-pentanediol, 3-methyl-1,5-pentanediol, or 1,3-propylene glycol. In the present invention, if the polyurethane is obtained by reacting a high molecular weight polyol or a chain extender polyol with a polyisocyanate compound, the polyurethane is not particularly limited.

In the present invention, a sponge for controlling discharge and a sponge for applying can have an integrated structure on a single container. When the container contains only the existing sponge for controlling discharge, the sponge for controlling discharge is spread over the container. Therefore, the contents can be discharged over a large area and can be cleaned with a puff, but this requires a separate puff, which is inconvenient. However, when the container contains only the sponge for controlling discharge, the contents discharged through the hole may splash, and it is difficult to control the amount discharged. On the other hand, when the sponge for controlling discharge and the sponge for applying of the present invention are integrated and contained in a container, the discharge amount can be controlled and a puff suitable for applying to the skin is provided, making the container easy to use.

In the cosmetic composition container of the present invention, the cosmetic composition is contained at the bottom of the container. When the container is squeezed, the cosmetic composition rises through the sponge for controlling discharge above, and can then be applied to the skin using an application sponge. Alternatively, a sponge for controlling discharge can be attached to the bottom of the container, and the cosmetic composition can be loaded into the sponge at the bottom of the container, where it flows into the sponge and then discharged. In other words, the cosmetic composition can be loaded into the bottom of the sponge for controlling discharge (Figure 2), or the cosmetic composition can be loaded into the sponge for controlling discharge at the moment the container is squeezed (Figure 1).

In one aspect of the present invention, the sponge and container are detachable ( FIG. 4 ). Thus, the user can fill the container with the desired amount of cosmetic composition, detach the sponge, and then reconnect the sponge to the container before use. Furthermore, the user can simply replace the sponge before use.

In one aspect of the present invention, the sponge may comprise a coated foam or a flocked foam. In another aspect of the present invention, the coated foam is made from a polymer, such as rubber, polyethylene or polyurethane foam, and is coated. Typically, the pore size of the coated foam is smaller than the pore size of the foam before the coating. In another aspect of the present invention, the flocked foam is made by bonding a polymer foam to a fabric. The fabric may be at least one material selected from cotton, acrylic resin, polyamide, nylon, polyester, silk and rayon, particularly, the fabric may be cotton, acrylic resin, polyamide, nylon, polyester, silk, cotton and acrylic resin, cotton and rayon, nylon, polyester and cotton, and acrylic resin and polyester.

When the container for a cosmetic composition according to one aspect of the present invention includes a sponge for controlling discharge of the cosmetic composition and a sponge for applying the cosmetic composition made of different materials, a user can feel various textures while using it, thereby providing a refreshing and satisfying application feeling.

The method for combining the sponge 10 for controlling discharge of the cosmetic composition and the sponge 20 for applying the cosmetic composition surrounding the sponge is not particularly limited, but the method may be an adhesive method. When a polyurethane-based material is used as an adhesive for fixing, separation during use can be prevented.

In one aspect of the present invention, at least one of the sponge for controlling the discharge of a cosmetic composition and the sponge for applying a cosmetic composition may include a foam having a hardness of 10 to 110, specifically 50 to 100, and more specifically 75 to 95, based on an ASKER durometer F scale. If the foam is too soft, with a hardness of less than 10, the cosmetic composition may be excessively discharged and applied, while if the foam is too hard, with a hardness exceeding 110, the cosmetic composition may be difficult to discharge and apply. As used herein, the term "hardness" of the foam refers to the firmness of the sponge before loading the composition.

In one aspect of the present invention, “cell number” refers to the number of cells per inch of sponge. In this specification, the cell number may be the average value of the number of cells on 1×1 square inch accurately measured using WI-QA-14 (ASTM standard).

The sponge for controlling the discharge of a cosmetic composition of the present invention may include a foam having a cell per inch (ppi) of 15 to 60, specifically 40 to 60, and more specifically 40 to 50. If the sponge for controlling discharge has a cell per inch (ppi) of less than 15, uniform discharge of the cosmetic composition may be difficult due to the small number of cells. If the sponge for controlling discharge has a cell per inch (ppi) of more than 60, the sponge for controlling discharge may separate due to increased pressure in the container, or discharge of the contents may be difficult. Therefore, when the ppi is 60 or less, the contents can be discharged smoothly without being affected by internal pressure.

The sponge for applying a cosmetic composition of the present invention may include a foam having a cell per inch (ppi) of 60 to 150, specifically 60 to 120, and more specifically 80 to 100. If the sponge for applying has a cell per inch (ppi) of less than 60, it may be difficult to uniformly discharge the cosmetic composition due to the small number of cells. If the sponge for applying has a cell per inch (ppi) of more than 150, it may be difficult to effectively apply the cosmetic composition due to the excessively small pore size, making it difficult to control the discharge of the cosmetic composition.

The sponge for controlling the discharge of a cosmetic composition according to the present invention may have a diameter of 5 to 11 mm and a length of 15 to 22.5 mm. If the diameter is less than 5 mm, the contents may not be discharged smoothly, while if the diameter exceeds 11 mm, the contents may be discharged excessively. The diameter and length of the sponge for controlling discharge can be adjusted according to the container structure.

The sponge for applying a cosmetic composition according to the present invention may have a diameter of 20 Φ or greater and a length of 2 cm or greater. If the diameter is less than 20 Φ, the size for application may be too small, potentially reducing usability. The length may vary depending on physical properties, but if the length is less than 2 cm, the cushioning effect may be reduced, resulting in decreased cosmetic adhesion, which may affect skin problems.

In one aspect of the present invention, at least one of the sponge for controlling the discharge of a cosmetic composition and the sponge for applying a cosmetic composition may include a foam having a pore diameter of 50 to 500 μm, specifically 80 to 400 μm. In one aspect of the present invention, "pore diameter" may be an average value measured using an optical microscope (NIKON ECLIPSE 80i). When the foam has a pore diameter within the above range, the foam is suitable for demonstrating the intended effects of the present invention. Specifically, if the pore diameter is less than 50 μm, discharge of the cosmetic composition may be difficult, while if the pore diameter exceeds 500 μm, the cosmetic composition may be excessively discharged and the surface may become rough. As a result, the cosmetic composition may not provide a soft touch when applied.

In one aspect of the present invention, a sponge for controlling the discharge of a cosmetic composition may include a foam having an open-pore structure. If the foam has a closed-pore structure, air bubbles may be trapped within the foam, making it difficult to effectively impregnate and discharge the cosmetic composition. Therefore, an open-pore structure is preferred. In the present invention, open-pore refers to a reticular structure, while closed-pore refers to a structure with air bubbles resembling balloons in the foam.

In one aspect of the present invention, the sponge for controlling discharge may have a mesh structure. In this case, the cosmetic composition may be easily impregnated into the sponge for controlling discharge, and the impregnation rate may be high.

In the present invention, the sponge for controlled drainage, which has a cross-linked (reticulated) structure, can be formed by subjecting the foam itself to a separate process to form a cross-linked structure. This cross-linked structure can also be referred to as a three-dimensional network structure. The cross-linked structure is formed by reticulating the cell membranes (walls) that form balloon-like shapes after foaming. This cross-linked structure is breathable and can also absorb and drain liquids. "Reticulation" refers to the process of converting the foamed structure into a reticulated structure after foaming, depending on the intended use. In sponge foam, reticulation refers to the process of reticulating the cell walls to form a reticulated structure. Therefore, the cross-linked structure that forms a three-dimensional membrane structure in the sponge of the present invention is completely different from existing foam structures that prevent cosmetic compositions from penetrating deeply. It also differs from structures that "cover" a polyurethane foam support with cloth, mesh, non-woven fabric, etc.

In one aspect of the present invention, a sponge for applying a cosmetic composition may include a foam having an open-pore or semi-open-pore structure. In the present invention, semi-open-pore refers to a sponge in which a portion of the foam has a reticular structure, with 10-100% of the cells being open. In another aspect of the present invention, the foam having an open-pore structure may have a relatively small pore diameter and may have a structure that prevents absorption of the cosmetic composition.

The dosage form of the cosmetic composition of the present invention may be an O/W or W/O type emulsified emulsion, or a liquid cosmetic emulsion, but is not limited thereto.

In one aspect of the present invention, the container for a cosmetic composition may be a container for a fluid-type cosmetic composition. This container allows for easy and appropriate dispensing of the fluid-type cosmetic composition, while also allowing for even and gentle application. Furthermore, the container facilitates the use of the cosmetic composition. In another aspect of the present invention, the fluid-type cosmetic composition encompasses all cosmetic compositions in fluid form, specifically, but not limited to, lotions, serums, liquid primers, liquid foundations, liquid concealers (BB), or liquid sunscreens.

Another aspect of the present invention relates to a container for a cosmetic composition, which can be used for a cosmetic composition having a viscosity of 20,000 cps or less, specifically 5,000 to 15,000 cps, or 1 to 5,000 cps, and more specifically 6,000 to 9,000 cps, or 1 to 3,000 cps. As used herein, viscosity can be measured using a viscometer, for example, a Brookfield viscometer (BROOKFIELD RVDV-III ULTRA (No. RY6521152)) with a No. 63 rotor and a rotation speed of 5 rpm.

In one aspect of the present invention, the container for the cosmetic composition may include a pump type container, a tube type container, a stick type container or a stamp type container. In another aspect of the present invention, the pump type container may include an airless pump type container, wherein the interior of the container is in a vacuum state.

In the container for a cosmetic composition according to one aspect of the present invention, a sponge for controlling discharge of the cosmetic composition and a sponge for spreading the cosmetic composition surrounding the sponge are located on the discharge hole of the container for the cosmetic composition, thereby not only controlling discharge of the cosmetic composition in the container for the cosmetic composition but also uniformly spreading the cosmetic composition.

In one aspect of the present invention, a container for a cosmetic composition may include a sponge for controlling the discharge of the cosmetic composition; and a sponge for applying the cosmetic composition, the sponge completely surrounding the sponge for controlling the discharge. In another aspect of the present invention, a container for a cosmetic composition may include a sponge for controlling the discharge of the cosmetic composition; and a sponge for applying the cosmetic composition, the sponge surrounding a portion of the sponge for controlling the discharge. In this case, when the cosmetic composition is discharged from the container through the portion of the sponge for controlling the discharge that is not surrounded by the sponge for application, the sponge for application can evenly and gently spread the discharged cosmetic composition on the skin. In another aspect of the present invention, the cosmetic composition can be discharged from multiple portions, such as the center portion of the top, side, or bottom of the sponge. In another aspect of the present invention, the container for a cosmetic composition includes a sponge for controlling the discharge of the cosmetic composition; and a sponge for applying the cosmetic composition that surrounds a portion of the sponge for controlling the discharge. During use of the cosmetic composition, the portion of the sponge for controlling the discharge that is not surrounded by the sponge for application can be exposed outside the container. Figures 1 and 2 show containers for cosmetic compositions, which include a foam for controlling the discharge of the cosmetic composition and a foam for applying the cosmetic composition, but these containers are for illustrative purposes only and should not limit the scope of the present invention.

In one aspect of the present invention, at least one of the sponges for controlling the discharge of the cosmetic composition and the sponge for applying the cosmetic composition can be selected from different materials and physical properties depending on the viscosity of the cosmetic composition. In another aspect of the present invention, in a cosmetic composition container, at least one of the sponges for controlling the discharge of the cosmetic composition and the sponge for applying the cosmetic composition can be replaced to accommodate a sponge selected based on the desired cosmetic product.

In one aspect, the present invention provides a cosmetic product comprising: a cosmetic composition; and a container for the cosmetic composition. The cosmetic product comprising the container for the cosmetic composition can easily and appropriately discharge the cosmetic composition while being able to evenly and gently apply the cosmetic composition, thereby making the cosmetic composition convenient to use.

The following examples and experiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[Preparation Example] Preparation of cosmetic composition

As shown in Table 1 below, cosmetic compositions with viscosities ranging from 5,000 to 15,000 cps were prepared. Specifically, an oily component was dissolved, and then a colorant was added and dispersed. Separately, an aqueous component was mixed and then added to the prepared oily component to obtain cosmetic compositions with viscosities ranging from 5,000 to 15,000 cps as a preparation example. The viscosity of the cosmetic compositions was measured using a Brookfield viscometer (BROOKFIELD VDV-III ULTRA (No. RY6521152)) with a No. 63 rotor and a rotation speed of 5 rpm.

【Table 1】

[Test Example] Evaluation of the effect of containers for cosmetic compositions according to type

The cosmetic compositions prepared in the above preparation examples were placed in various containers including foams, and the containers' usability, composition discharge capacity, and spreadability were evaluated. As shown in the table below, Examples 1-4 are pump-, tube-, stick-, and stamp-type containers that include a sponge for controlling discharge of the cosmetic composition and a foam for applying the cosmetic composition. Comparative Example 1 is a general-purpose plastic container, blow-molded, and equipped with a sponge for application without a separate discharge hole. Comparative Example 2 is a general-purpose plastic container, blow-molded, and equipped with a sponge for application with a separate discharge hole.

The physical properties of the foam contained in each container are shown in Table 2 below. Hardness was measured using an ASKER F-type durometer; the number of cells per inch (ppi) is the average number of cells accurately measured on a 1 x 1 square inch using a WI-QA-14 (ASTM standard); and the cell diameter is the average value measured using an optical microscope (NIKON ECLIPSE 80i). The evaluation results are listed in Table 3 below. The usability in Table 3 is based on a questionnaire survey of 20 regular cosmetic users. Dispensability and spreadability are expressed based on an appropriate single use (0.1-0.4 g).

【Table 2】

【Table 3】

* In Table 3, ◎ represents very good, ○ represents good, △ represents fair, and X represents poor.

As can be seen from the above results, the usability and discharge capabilities of Examples 1-4 were superior to those of the Comparative Examples. In particular, Examples 1-4, which included a sponge for controlling the discharge of the cosmetic composition, demonstrated significantly better discharge capabilities than the Comparative Examples. That is, unlike existing containers for cosmetic compositions, it was confirmed that the cosmetic composition container of the present invention, by including both a sponge for application and a sponge for controlling discharge, facilitated the discharge of the cosmetic composition and allowed for uniform and convenient application of the cosmetic composition.
