    • 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.
    • 一种防回流塞,容器和倾倒装置,其中容器主体和插头构件以简单的形状分开设置,并且插塞构件和弹性构件之间的紧密接触性得到增强,以提高防回流功能 被提供。 防回流塞包括由用于限定具有入口和出口的流路的薄膜形成的弹性膜,以及保持在弹性膜的流动路径中并形成有球形密封件的球形塞构件 表面用于通过与弹性膜的中间部分紧密弹性接触来限制流体流动。 在容器中,防回流塞被安装在容纳内容物的容器主体的容器开口上。 倾倒装置例如包括收容容纳容器的容器保持架,容器主体从容器开口侧被加压而收缩变形。
