Abstract: The present disclosure relates to a container device capable of storing and discharging liquid. A container device according to the present disclosure includes a pouch having the elastic property; a rigid container having a rigid outer case compared to the pouch and having a container opening at one side thereof; a coupling unit coupled to the container opening and for coupling an opening of the pouch with the container opening; and an air passage formed at the rigid container or the coupling unit. When the pressure is applied to the inside of the pouch and the volume of the pouch is increased, the volume of a space between the pouch and the rigid container is reduced by an increase in the volume of the pouch, such that the air in the space is discharged to the outside of the rigid container through the air passage to perform the depressurization of the space.

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.

Abstract: A method of manufacturing a container includes: a container preparing step of placing a filling space of the pouch inside a receiving space of an outer container; and a pouch expanding step of supplying air to the filling space of the pouch and expanding the pouch toward the receiving space.

Abstract: Disclosed is a content discharging device according to an embodiment of the present disclosure. The content discharging device includes a flexible pouch having an opening at one side thereof, a fixing ring coupled to the opening, and a discharging portion coupled to the fixing ring and capable of conveying content. The flexible pouch is inserted into a rigid container with a shape, and the discharging portion is coupled to the opening of the rigid container.
