초록 ▼

A backflow preventing plug, a container, and a pouring device in which a container body and a plug member are provided separately in a simple shape, and tight-contact property between the plug member and a resilient member is enhanced to improve a backflow preventing function are provided.A backflow-preventing plug includes a resilient membrane formed of a thin film for defining a flow path having an inlet port and an outlet port, and a ball-shaped plug member retained in the flow path of the resilient membrane and formed with a spherical sealing surface for restricting fluid flow by coming into tight resilient contact with a middle portion of the resilient membrane. In a container, the backflow preventing plug is attached to a container opening of a container body accommodating contents. A pouring device includes, for example, a container holder accommodating and holding the container and allowing the container body to be pressurized from the container opening side to be contractingly deformed.
