The container includes a body, an extension tube, a discharge cap, a cover, wings, a fixing member, an operating member, and a spring. The wings are inwardly protrudently formed on the inner wall of the discharge cap and regularly spaced apart from each other, a space formed between the wings. The fixing member is fitted into the wings. The operating member is configured in such way that its upper end is inserted into the fixing member and its lower end forms a closing plate for closing the passage. The spring is placed between the operating member and the fixing member for allowing the operating member to elastically tightly close the passage.
