Field of the Disclosure
The present disclosure relates to pact-typed cosmetics. The pact-typed cosmetic is a bead-type liquid foundation cosmetic composition disposed within in a mesh net-equipped container.
Description of the Potentially Related Art
Conventional liquid cosmetic compositions are typically disposed in a vacuum container, a pump-type container, or a glass container. The containers are then typically distributed and stored before acquisition by a consumer. However, the containers are not easy to carry, so studies relating to liquid cosmetic compositions that are easy to carry have been undertaken.
A pact-type container is an example of a container that carries a liquid cosmetic composition. There are various considerations in filling a pact-type container with a liquid cosmetic composition, for example, whether a carrier for a liquid cosmetic composition is suitable for the pact-type container, whether the carrier is suitable for carrying the liquid cosmetic composition, whether the carrier can maintain the cosmetic composition evenly for a long period of time, and whether the cosmetic composition included in the carrier can be released at a proper time in a proper amount. An ideal carrier for such a cosmetic composition would be suitable for the pact-type container considering all of the above.
Patent reference 1 (Korean Patent Publication No. 10-2013-0083852) describes a carrier for a cosmetic composition containing a foamed urethane layer-structure and a cosmetic.
Patent reference 2 (Korean Patent Publication No. 10-2009-0100643) describes a cosmetic composition filled in a pact-type container, wherein the cosmetic composition is a W/O (water in oil) type UV blocking composition with low viscosity. The W/O type UV blocking composition with low viscosity is impregnated in urethane foam, which is packed in a pact-type container.
Patent reference 3 (Korean Patent Publication No. 10-2012-0108509) discloses a study attempting to improve the physical properties of a cosmetic composition carrier including urethane foam.
However, the cushion-type products using urethane foam of Patent references 1-3 have a problem of big cosmetic composition loss. For example, the basic structure of the cushion-type cosmetic results in the wasteful impregnation of a cosmetic composition in the foam. Therefore, there is a long felt but unsolved need for a portable cosmetic that minimizes cosmetic composition loss and has equal convenience in portability to the conventional cushion-type products.
Patent reference 4 (Korean Patent Publication No. 10-2014-0144264) discloses a method of preparing a bead-type cosmetic composition based on the idea that produces ball type ice-cream via cryogenic freezing in the field of food industry.
It is an object of the present disclosure to provide a cosmetic that is not only as portable as the conventional cushion-type products but also minimizes cosmetic ingredient loss. To achieve the above object, disclosed is a pact-type cosmetic, wherein the bead-type liquid foundation cosmetic composition is 0.1-1.0% weight/volume (w/v) gel forming material; 10-20% w/v oil component; 50-60% w/v water component; 1-10% w/v thickener; 1-10% w/v coloring agent; and 15-25% w/v emulsifier. Disclosed is a pact-type cosmetic disposed in a cosmetic container having a body and a lid, in which a mesh is disposed on the top of the body of the cosmetic container.
The disclosed pact-type cosmetic disposed in the body of the cosmetic container not only maintains the portability of the conventional cushion-type products but also minimizes the loss of the pact-type cosmetic because urethane foam is not used as a carrier for the pact-type cosmetic.
Disclosed is a pact-type cosmetic wherein the bead-type liquid foundation cosmetic composition is 0.1-1.0% w/v gel forming material; 10-20% w/v oil component; 50-60% w/v water component; 1-10% w/v thickener; 1-10% w/v coloring agent; and 15-25% w/v emulsifier.

As shown in
The method for assembling the cosmetic container to prevent the flow of the bead-type liquid foundation cosmetic composition according to an example of the present invention and the instruction for the use are explained hereinafter.
To assemble the cosmetic container, the mesh (30) is first attached to the mesh coupling member (50), as shown in
The bead-type liquid foundation cosmetic composition is capable of filling the container body (10) having the protrusions for preventing movement (40) formed on the bottom floor of the container. The mesh net coupling member (50) having the mesh (30) connected thereto is attached to the upper part of the container body (10). The outer periphery of the upper extension part (544) of the mesh fixing part (54) is tightly connected to the inner periphery of the container body (10) and the horizontal extension part (546) is placed on the top of the inlet (14) of the container body (10).
Lastly, the lid (20) is connected to the container body (10). As a result, the cosmetic container designed to prevent the flow of the bead-type liquid foundation cosmetic composition of the invention is assembled.
When the protrusions (40) are formed in the inside of the compact container, the container body (10) assembled as described above is placed in the inside of the outer container (70) with the outer container lid (80) connected by hinge.
To use the cosmetic container designed to prevent the flow of the bead-type liquid foundation cosmetic composition which has been assembled as shown above, first the lid (20) is separated from the container body (10). As shown in
When the protrusions for preventing movement (40) designed to prevent the flow of the bead-type liquid foundation cosmetic composition are formed in the compact container, the outer container lid (80) is first opened from the outer container (70), as shown in
As the bead-type liquid foundation cosmetic composition is consumed, the cosmetic container has a space inside. Then, the bead-type liquid foundation cosmetic composition is moving around in the space freely, so even though the mesh net (30) is pressed the beads are not broken. Since the cosmetic container of the present invention designed to prevent the flow of the bead-type liquid foundation cosmetic composition has the protrusions for preventing movement (40) on the bottom floor of the container body (10) containing the bead-type liquid foundation cosmetic composition, the movement of the bead-type liquid foundation cosmetic composition is minimized whenever the mesh net (30) is scrubbed with a puff in any direction and accordingly the bead-type liquid foundation cosmetic composition can be easily broken out.
To use the cosmetic composition contained in the conventional cushion compact containing urethane foam, a puff is used to press the urethane foam and the stained composition in the puff is spread on the skin. At this time, about 20% of the cosmetic composition included in the urethane foam is not smeared onto the puff, suggesting that a large amount of the cosmetic composition is lost.
On the contrary, the cosmetic composition prepared in Examples 1-4 are filled in the cosmetic container of the invention and used by a puff provided from the cosmetic container, most of the BB cream filled in the cosmetic container along the bottom structure is smeared onto the puff so that the BB cream is hardly wasted, indicating the container of the invention is advantageous in saving BB cream.
The cosmetic comprising a cosmetic composition of bead-type liquid foundation filled in a mesh equipped cosmetic container maintains portability as the conventional cushion-type cosmetic has and at the same time is more advantageous in preventing the loss of cosmetic ingredients because urethane foam is not used as a carrier for the cosmetic composition herein.
Practical and presently preferred embodiments of the present invention are illustrative as shown in the following Examples.
However, it will be appreciated that those skilled in the art, on consideration of this disclosure, may make modifications and improvements within the spirit and scope of the present invention.
