Title:
可撓性容器用中栓部材および可撓性容器
Document Type and Number:
Japanese Patent JP6919885
Kind Code:
B2
Abstract:
An inner plug mounted to the neck of the flexible container has a cylindrical hollow portion that contains a valve element, a valve seat disposed below the valve element, a permanent magnet disposed below the valve seat that attracts the valve element to the valve seat, and a discharge outlet in the top of the inner plug to allow discharge of fluid contents of the container via a flow path extending from the discharge outlet to the container body via a void formed between the valve element and the valve seat. The valve element is movable between a closed valve state, in which the valve element contacts the valve seat, and the bottom of the discharge outlet. An open valve state is achieved once pressure inside the container overcomes the magnetic attraction of the valve element to the valve seat and forces the valve element away from the valve seat.
