Abstract
A plug structure for taking out liquid from a container includes a plug body press-fitted into a container inlet port. The plug body is resiliently deformable with a lower portion being formed into a ring shape and being provided with slits in an axial direction. The plug structure includes a locking claw on an outer peripheral surface of the plug body, which projects toward an inner wall surface of the container inlet port. The locking claw has a minimum diameter substantially the same as or smaller than the inner diameter of the container inlet port. The locking claw has a maximum diameter that is larger than the inner diameter of the container inlet port. The plug structure includes a valve operating portion that presses a valve on a socket connected to the plug body. The valve operating portion is provided on an upper end inlet port of the siphon tube.
