Description

CROSS REFERENCE TO RELATED APPLICATION The present application claims priority to Korean Patent Applications Nos. 10-2022-0161318, filed Nov. 28, 2022 and 10-2023-0144628, filed Oct. 26, 2023 the entire contents of which are incorporated herein for all purposes by this reference. BACKGROUND Technical Field The present disclosure relates to a cosmetic container and, in more detail, a cosmetic refill container having an air block structure that can be refilled with a cosmetic preparation without contact with air by employing an air block structure, and a cosmetic container having the cosmetic refill container. Description of the Related Art In general, as a method of using a liquid-state cosmetic preparation such as cosmetics that it is preferable to use by a small amount and an accurate amount at a time including eye cream, a method of individually packaging preparations in capsules, etc., by the amount to be used at each time of use has been used in the related art. However, such an individual packaging method has a problem of inefficiency because even after a user uses a preparation, a relatively large amount of cosmetic preparation remains in a capsule. In order to overcome the problem of such an individual packaging method, a configuration designed for a user to take out and use a cosmetic preparation every time the user uses the preparation using a taking-out instrument such as a common pipette or syringe or a taking-out instrument having the configuration of a push pump after the preparation is put into a container has been disclosed. Meanwhile, the cosmetic preparation stored in a refill container is generally directly exposed to the air when a cosmetic container is refilled. That is, when the cap of a refill container is opened in the process of replacing a refill container, the cosmetic preparation stored in the refill container comes in contact with the air, and from this moment, the cosmetic preparation starts becoming rancid or is contaminated and the lifespan shortens, so there is a need for measures for solving this problem. The above description is the background for helping understand the present disclosure and does not means the related art well known in the art. SUMMARY Accordingly, an objective of the present disclosure is to provide a cosmetic refill container having an air block structure that can be refilled with a cosmetic preparation without contact with air by employing an air block structure, and a cosmetic container having the cosmetic refill container. According to an aspect of the present disclosure, there may be provided a cosmetic refill container that includes: a refill container main body configured to store a cosmetic preparation therein and coupled to a container main body; a sealing coupling unit coupled to the refill container main body and provided as a discharge passage of the cosmetic preparation stored in the refill container main body; and a sealing member coupled to the sealing coupling unit and configured to prevent contact between the cosmetic preparation stored in the refill container main body and external air. The sealing coupling unit may include: a first body coupled to a head of the refill container main body; and a second body formed at a lower portion of the first body and having the sealing member coupled thereto. The sealing coupling unit may further include a supporting step formed on an inner wall of a joint area between the first body and the second body and locking and supporting a housing of a pumping unit coupled to the container main body. The sealing member may include: a sealing body coupled to a body hole formed at the sealing coupling unit; a sealing flange formed at the sealing body and configured to cover an area over the body hole; and a sealing expansion formed at the sealing body to protrude under the body hole and configured to prevent separation of the sealing body. A supporting protrusion may be formed on a bottom inside the second body of the sealing coupling unit and a bottom of the sealing flange is supported on the supporting protrusion. The refill container main body may include a refill container body having the sealing coupling unit coupled thereto and a body expansion configured to support a bottom of the container main body may be formed at the refill container main body. The refill container main body may further include a refill cap detachably coupled to the refill container body and the refill cap may be coupled to the refill container body with the sealing coupling unit coupled to the refill container body. The refill container main body may further include a refill container piston disposed in the refill container body and configured to guide discharge of the cosmetic preparation. Further, according to another aspect of the present disclosure, there may be provided a cosmetic container that includes: a container main body; a refill container coupled to the container main body and configured to store a cosmetic preparation
