PROBLEM TO BE SOLVED: To provide a squeeze extraction inside plug for stably extracting liquid in the direction along the axis of an extraction cylinder, by avoiding the occurrence of a violently behaving phenomenon of the liquid extracted by squeeze.SOLUTION: A squeeze extraction inside plug 1 is installed in a port neck part 51 of a container body 50 having a squeezable trunk part, and extracts the liquid R in the container body 50 from an extraction port 29a when squeezing the trunk part, and is provided with the extraction cylinder 29 for forming the extraction port 29a in a tip part, and an inner peripheral surface of the extraction cylinder 29 forms an area of continuing with the extraction port 29a as a cross-sectional constant straight part 29b along the axis O of the extraction cylinder 29, and an angle &thetas; formed by a tip surface 29b of the extraction cylinder 29 and the straight part 29b is set to 90 degrees or less. |
