ABSTRACT:
An applicator includes: a barrel cylinder; an application portion in front of the barrel cylinder; a tank placed behind the application portion for storing liquid inside the barrel cylinder; a pipe (conduit) for conducting the liquid ejected from the tank to the application portion; a piston which is fitted in the tank as to slide in the axial direction ensuring a watertight contact; and a liquid pushing device placed in the rear part of the barrel cylinder for pushing the liquid from the tank to the application portion via the pipe by moving the piston forwards. In this applicator, the bore of the pipe is set between 0.2 mm and 1.7 mm, and the viscosity of the liquid measured by the E-type viscometer within an temperature range for operation is set between 20 mpa.sec and 100,000 mpa.sec. Further, the barrel cylinder is formed of PP, and the piston is formed of HDPE or LLDPE.
