Description

TECHNICAL FIELD The present invention relates to a content container, and more specifically, to a content container, which can tightly seal the contents in a locked state and release the locked state by simply rotating an overcap to allow the contents to be discharged. BACKGROUND ART In general, a dropper-type cosmetic container is configured to allow a discharge portion having a pipette to be detachably attached to a container. A dropper-type cosmetic container, in a state in which the pipette is inserted into the container, is implemented to suck and discharge the contents when a user presses a button. Alternatively, a tube-type cosmetic container, in a state in which a pipette-shaped nozzle is coupled to one end thereof, is implemented to discharge the contents through the nozzle when the user directly presses the container. The cosmetic containers can suck and directly discharge a small amount of contents to an application area, and minimize exposure of the contents to the external environment during storage and use, so are widely adopted for containers for functional cosmetics such as serum, essence, and eye cream. However, in a case in which functional substances prone to chemical changes due to external environments, such as retinol, vitamins, etc., are included in the contents, since the contents may be deteriorated due to exposure to light, oxygen, moisture, etc., during the distribution, storage, and other processes of cosmetic containers, the dropper-type cosmetic cosmetic containers have a limitation in that it is insufficient to protect the contents from being deteriorated by external environments. Therefore, there is a demand for technology to solve the problem. DISCLOSURE Technical Problem Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the related art, and it is an objective of the present invention to provide a content container, which can tightly seal the contents in a locked state and release the locked state by simply rotating an overcap to allow the contents to be discharged.
