Abstract:
A liquid applicator for applying an application liquid comprising:a barrel body composed of a front barrel and a rear barrel separably fitted to the front barrel, the front barrel having a partition therein which sections the front barrel into a front sleeve and a rear sleeve, the partition having a surface on the front sleeve side of the partition which is formed with a stepped concave portion depressed in its center with respect to an outer peripheral part thereof;a trunk core for allowing the application liquid to permeate therethrough and be supplied to a pen core;a collector having a central shaft forming a communication passage is disposed in the front barrel, the collector having a front end in which the pen core is inserted, the trunk core being disposed in the passage, the pen core being joined to a front end portion of the trunk core, the central shaft being continuous from a rear end of the pen core and having a communication passage for holding the front end portion of the trunk core, and a plurality of collector vanes arranged on an outer periphery of the collector and spaced at intervals in an axial direction for temporarily retaining the application liquid within the spacing, the collector being inserted inside the front sleeve in a manner that allows an outer peripheral portion to communicate with the atmosphere, wherein a liquid conduit slit is formed in the collector such that the slit extends between the central shaft and internal edges of the collector vanes, and a rear end of the collector is abutted against the stepped concave portion so as to define a first gap with respect to the center of the stepped concave portion while the first gap and the liquid conduit slit are communicated with each other;a cylindrical projection extends from the partition into the rear sleeve and defines a communication passage into which a rear end of the trunk core extends, the trunk core being spaced from an inner wall of the projection so as to define a second gap; anda replaceable cartridge for storing the application liquid being removably mounted to the cylindrical projection, wherein the application liquid inside the cartridge is supplied to the pen core by way of the trunk core while the application liquid is also temporarily retained in the spacing between the collector vanes by virtue of the second gap being in fluid communication with the first gap and the liquid conduit slit; and the stepped concave portion on the partition is formed with a plurality of grooves extending radially outwardly from an axial center.
