<P>PROBLEM TO BE SOLVED: To provide a discharge container which can prevent contamination caused by a microorganism and the unintended drop or drip of liquid. <P>SOLUTION: A discharge container 1 is configured by assembling a plug body 11 to a mouth 9a of a double container 9 comprising an outer layer body 3, an inner layer body 5 and an outside air introduction hole 7 formed in a mouth 3a of the outer layer body 3. The plug body 11 includes a base 13, a tubular discharge valve 29 and a suction valve 31. In the plug body, a tubular body 13d is erected of which the tip is closed and which has a discharge hole 21 on its sidewall, and the base includes a suction hole 19 communicating to the outside air introduction hole 7. The tubular discharge valve is composed of an elastic material, closes an outlet of a feed path P for a content liquid and is elastically deformed by liquid pressure to be pushed to open, thereby allowing the content liquid to flow out via the outlet of the feed path P. The suction valve is composed of an elastic material, closes the suction hole 19 and is elastically deformed by negative pressure in the outer layer body to open the suction hole 19. At an inner edge of an upper end of the discharge valve 29, a projection 29a is formed which abuts on an outer surface of the tubular body 13d all over the circumference and seals the outlet of the feed path P. <P>COPYRIGHT: (C)2013,JPO&INPIT |
