Abstract: The present disclosure relates to a pouch assembly for storing a liquid and a container device using the same. A pouch assembly according to an embodiment of the present disclosure includes a pouch unit which is formed of an elastic material and in which a charging space for charging the liquid is formed. The pouch unit includes a pouch unit body in which the charging space and a pouch-side opening communicating with the charging space on one side thereof are formed, a pouch-side catch which is formed on one side of the pouch unit body and in which an outer circumferential side thereof in a state in which the pouch-side catch surrounds the pouch-side opening further extends outward from an outer surface side of the pouch unit body, and a selective sealing unit which is disposed at an upper side of the pouch-side catch and selectively opens/closes the pouch-side opening.

Abstract: The present disclosure relates to a content charging device for a container apparatus in which a liquid is stored, and a content charging method using the same. In the content charging device of the preset disclosure, the container apparatus includes an external container in which a storage space is formed and which includes a container-side opening communicating with the storage space; and a pouch assembly installed on the external container. The pouch assembly includes a pouch unit which is formed of an elastic material and has a charging space formed to be charged with a liquid, wherein the pouch unit is partly inserted into the storage space through the container-side opening. The content charging device includes a charging means that is inserted into the charging space of the pouch unit, has flow holes which are formed on one side thereof and through which air or a content is caused to flow, and is slidable toward an end of the pouch unit from a pouch-side opening of the pouch unit.
