Abstract:
A knock-type applicator comprising: a cylindrical shell having a distal end and a coating liquid storage chamber for storing a coating liquid; a writing tip mounted in the cylindrical shell for slidable movement therein and through an opening portion formed in the distal end of the cylindrical shell, the writing tip having a fiber body comprised of a plurality of fibers forming flow passages for receiving the coating liquid stored in the coating liquid storage chamber; a valve mechanism disposed between the writing tip and the coating liquid storage chamber for controlling a flow of coating liquid from the coating liquid storage chamber to the fibers of the writing tip, the valve mechanism having a valve element connected to the writing tip; and a plurality of ribs extending from an inner wall of the opening portion formed in the distal end of the cylindrical shell and extending in a lengthwise direction of the cylindrical shell for projecting into the writing tip during sliding movement of the writing tip so that the fibers of the writing tip are split by the ribs and solidified, gelled or viscous matters formed by the coating liquid inside the fibers are peeled off the fibers and flow passages inside the writing tip for the coating liquid are recovered, a diameter of an inscribed circle connecting apexes of the ribs being dimensioned smaller than a maximum diameter of the writing tip.
