Applicator

An applicator comprising:

• a barrel body storing a liquid therein;
• a ball holder having a ball house defined by a cylindrical inner surface having an inside diameter and a longitudinal axis, said ball house having an ejecting opening having an inside diameter smaller than said inside diameter of said ball house, said ejecting opening being surrounded by an inner wall at a front end of said ball holder, said ejecting opening allowing the liquid from said barrel body to flow out of said applicator;
• a ball rotatably held in said ball house, said ball being partially exposed to the outside through said ejecting opening so as to serve as an applying point, said ball being held movably between a first position centered on said longitudinal axis and abutting said inner wall around said ejecting opening, and a second position laterally offset from said longitudinal axis and separated from the abutting position, whereby said ejecting opening is closed and opened, wherein, when part of said ball is pressed on an applied surface, said ball is moved rearward from the abutting position and laterally from the longitudinal axis such that said ball is separated from the abutting position and the liquid is ejected from a gap between said ejecting opening inner wall and said ball to thereby apply the liquid on the applied surface, said ball having a diameter less than the diameter of said ball house;
• a spherical evading member disposed on the rear side of said ball inside said ball house, a front side of said evading member being in contact with the rear side of said ball and movable together with said ball rearward to a position laterally offset from the longitudinal axis;
• a ball seat disposed in the rear part of said ball house, said ball seat centered on said longitudinal axis, said ball seat receiving the rear side of said evading member when part of said ball is pressed against an applied surface so that said ball is moved backward into contact with a front side of said evading member, and a rear side of said evading member is pressed into contact with said ball seat and is laterally offset from the longitudinal axis, such that a gap is formed between a portion of the evading member and a portion of the ball seat;
• a liquid conduit provided in a central part of said ball seat, for conducting the liquid from said barrel body into said ball house;
• a plurality of longitudinal grooves radially arranged about said liquid conduit as a center, said grooves being formed on the inner wall of said liquid conduit along the conducting direction of the liquid along said longitudinal axis;
• and
• a pressing means disposed through said liquid conduit and abutting the rear side of said evading member so as to urge said evading member forward into contact with said ball to urge said ball forward into the abutting position.
