Content filling apparatus and content filling method using same

A content charging device for a container apparatus that 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 and including 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 comprising
• 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 wherein fluid channels, which are formed between a part of an inner wall of an opening of the external container and a part of the pouch assembly and provide communication between an internal space of the external container and an outside of the external container, are formed in the container apparatus;
• and
• the content charging device further comprises a suction means having a suction means body which surrounds one end of each fluid channel, an inner surface of which is spaced apart from the one end of each fluid channel, and which has a suction space formed between the inner surface and the container apparatus;
• and
• a suction hole communicating with the suction space is formed in the suction means body,
• wherein the suction means further includes a pouch unit edge pressing unit that presses an upper edge of the pouch unit seated on an end of the external container toward the end of the external container,
• wherein the pouch unit edge pressing unit includes a pressing bracket that is disposed in the suction space of the suction means body so as to be movable in a vertical direction and includes a pressing region that brings the upper edge of the pouch unit into close contact with the end of the external container, and an elastic unit that provides an elastic force to the pressing bracket in a vertical direction,
• wherein one side of the elastic unit comes into contact with an inner surface of the suction means body, and the other side of the elastic unit comes into contact with the pressing region of the pressing bracket,
• wherein the pouch unit edge pressing unit further includes a pair of guide brackets which are formed to extend in the same direction as a moving direction of the pressing bracket, into which a part of the pressing bracket is fitted, and which are fixed to an inner surface of the suction means body on one side thereof.
