LIQUID WITHDRAWING SYSTEM AND LIQUID WITHDRAWING DEVICE

摘要

Provided is a liquid withdrawing system (100) in which a plug (10) attached to an opening portion (21) of an inner container (20) includes a cylindrical contact portion (11) being in contact with an inner circumferential surface of the opening portion (21), an engaging claw (12) connected to a lower end of the cylindrical contact portion (11), a cylindrical guide portion (13) connected to a lower end of the engaging claw (12), a siphon tube (14) inserted toward a bottom surface (20b) of the inner container (20) and a flow channel portion (15) having a liquid flow channel and a gas flow channel, and in the liquid withdrawing system (100), a second length (L2) in an axis (X2) direction from a lower end (13a) of the cylindrical guide portion (13) to a distal end (14a) of the siphon tube (14) is shorter than a first length (L1) in an axis (X1) direction from an upper end of the opening portion (21) to the bottom surface (20b) of the inner container (20), and a third length (L3) in the axis (X2) direction from the engaging claw (12) to the distal end (14a) of the siphon tube (14) is longer than the first length (L1).
