Applicator, for by flowing material endoceliac applicator body include be used to be inserted into body cavity. The indoor applicator of chamber embraces the flowing material of trunk. Plunger pressure is applied to flowing material, and when push-in chamber, which generates suction, work as extraction. Side opening is designed with check valve, and thus, it is possible to make outer surface of the flowing material of outflow by opening from chamber to applicator, when pressure is applied to plunger, the suction for inhibiting incoming fluid to generate when being inserted into chamber from applicator by the opening passes through plunger. Chocking construction inhibits to push movement in stop position, can make to move across stop position, when additional thrust is applied, and by stop position retraction, without interfering.
