<p><P>PROBLEM TO BE SOLVED: To provide a new syringe type ejector capable of ejecting a liquid as a foam-like liquid or a mist-like liquid without impairing the operability even if the amount of the liquid is small while enabling the content liquid to be contained in a cartridge. <P>SOLUTION: The ejector includes: an operation device 1B which allows a rod 3c disposed in a through-hole formed in a distal end cylindrical portion 2c of a syringe 2 to be formed extending in a piston 3a slidably disposed in the syringe 2, and forms a path r1 of air force-fed by the piston 3a between the rod 3c and the distal end cylindrical portion 2c; a cylindrical member 6 which is filled with a content liquid C and has a plunger 7 for extruding the content liquid C by using pressing force from the rod 3c as urging force; a nozzle 8 which houses the cylindrical member 6 in the inside and is attached to the distal end cylindrical portion 2c; and a mesh ring 9 which is housed in the nozzle 8 and forms a foam-like content liquid from the content liquid C extruded from the cylindrical member 6 via the air force-fed by the piston 3a. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
