The present invention relates to a cap assembly of an erect mineral water bottle and, more specifically, to a cap assembly of an erect mineral water bottle, which prevents water from remaining regardless of the size of a mineral water bottle by forming an extendable wrinkle part in a suction pipe and efficiently performs a pumping action. The cap assembly of the erect mineral water bottle, which provides a pipeline where mineral water is pumped, comprises: a main stopper which is composed of an edge part for surrounding the edge surface of an opened part, a shielding part for shielding the opened part, and a coupling pipe protruding to both sides of the shielding part; a suction pipe which is coupled to one end of the coupling pipe to be arranged inside the mineral water bottle and has a pipeline connected to the coupling pipe and one or more extendable wrinkle parts; a fixing member which is coupled to the edge part of the main stopper and presses the main stopper to the edge of the opened part of the mineral water bottle; and a sealing member which is inserted into the gap between the opened part and the main stopper. |
