ABSTRACT:
A plug body having an inner cylindrical member with short engagement receivers and long engagement receivers together with steps, an operating button with short engaging elements and long engaging elements that are respectively received by the short engagement receivers and long engagement receivers, a rotatable slider provided with protrusions, a valve body with a valve stem which is inserted into the rotatable slider and the inner cylindrical member, a spring that preloads the rotatable slider upwards so that the long and short engaging elements of the operating button alternatively make contact with the protrusions, causing the rotatable slider to rotate with a depression of the operating button. The liquid passage is opened when the long engaging elements of the operating button make contact with the protrusions of the rotatable slider. In this case, the operating button protrudes upward above the upper lid of the liquid container. In contrast, the liquid passage is closed when the short engaging elements of the operating button make contact with the protrusions of the rotatable slider, and in this case, the operating button is hidden below the upper lid. Thus, the valve open state is more easily checked visually.
