PROBLEM TO BE SOLVED: To provide a dispenser capable of surely drawing contents by back suction.
SOLUTION: The dispenser is provided with: a syringe main body 1 which has a filling space for the contents and for which an extraction nozzle is mounted on the distal end a plunger 2 to be slid inside the syringe main body 1 by the addition of push-in force to extract the contents inside the filling space m from the distal end of the extraction nozzle and an O ring 3 which is installed in a groove part 2a formed at the distal end part of the plunger 2, is slidable along the inner wall surface of the syringe main body 1 and seals the filling space m mutually between the plunger 2 and the syringe main body 1. In the dispenser, the groove part 2c of the plunger 2 is provided with a step part 4 for pressurizing the inner diameter end of the O ring 3 as the plunger 2 is pushed in to compress and elastically displace it, restoring the O ring 3 by the release of loads relating to the push-in, sliding the plunger 2 in a direction opposite to the push-in direction and inducing the back suction of the contents.
