SYRINGE EJECTOR

摘要

Provided is a syringe ejector which is configured so that a content liquid is contained in a cartridge, so that the operability is not impaired even if the amount of the liquid is small, and so that the syringe ejector can eject the liquid as a foam-like liquid or a mist-like liquid. A syringe ejector comprises: an operation device (90) provided with a syringe (91), a piston (92a) which extrudes air within the syringe (91), and a rod (92c) which forms a gap (r1) between the rod (92c) and the front end tube section (91c) of the syringe; an outer tube member (14) having an ejection opening (1a) and mounted to the front end tube section (91c); an inner tube member (11) disposed inside the outer tube member (14); and a barrier member (B) for transforming liquid (M) into a foam-like liquid. The inner tube member (11) incorporates a plunger (13) for extruding, toward a liquid path (r10), the liquid (M) poured in the inner tube member (11). The inner tube member (11) and the outer tube member (14) have air paths (r12-r15) formed therebetween. The air paths (r12-r15) cause air, which has been extruded from the gap (r1), to join the liquid (M) extruded from the liquid path (r10).
