PURPOSE: A method of manufacturing a liquid container is provided to improve and to stably maintain sealability. CONSTITUTION: A liquid container comprises a container part(10) having a container body part of which at least one of an upper end and a lower end is opened; and a connection pipe(20) which is combined to at least one of the opened upper and lower ends of the container body part to be connected to an opening of the container body part. The connection pipe is formed of a rigid material, and a connecting cavity is formed in a region near the container body part penetrating in a widthward direction. The container part is formed of a soft material. The container part includes an inside cut off pipe part(12) and an outside cut off pipe part(13) which are extended in a longitudinal direction of the container body part from the container body part to adhere an outer surface and an inner surface of the connection pipe, and a connection bar(14) connecting the inside cut off pipe part and the outside cut off pipe part through the connection cavity. The connection pipe comprises a connection pipe body part(21) in a pipe shape, and a connection pipe cut off part(22) in a pipe shape in which the connection cavity penetrating in a thickness direction is formed and extended from the connection body part to make a T-shaped cross-section in cooperation with the connection body part. The inside cut off pipe part and the outside cut off pipe part are each adhered to an inner surface and an outer surface of the connection pipe cut off part. A binding ring(31) has a pressing rib(31a) curved inwardly at an upper part. A cap has a pressure rib(32a) cured outwardly at a lower part. |
