Direct liquid type pen-shaped eyeliner

A direct liquid type pen-shaped eyeliner forming a rod shape, guiding a coating material toward a front end side from a rear end side in a longitudinal direction, and ejecting the coating material from the front end side, the direct liquid type pen-shaped eyeliner comprising:

• a coating material tank where a coating material accommodating space accommodating the coating material is formed;
• an application member having a hole portion recessed from an end surface on the rear end side toward the front end side and ejecting the coating material;
• a coating material feeder forming a rod shape extending in the longitudinal direction, inserted into the hole portion from the rear end side, extending into the coating material accommodating space, and supplying the coating material in the coating material tank to the application member;
• and
• a pressure fluctuation buffer member forming a tubular shape extending in the longitudinal direction, disposed on an outer peripheral side of the coating material feeder, forming a buffer space connected to the coating material accommodating space inside, and buffering a pressure fluctuation in the coating material accommodating space by flow of the coating material and air between the coating material accommodating space and the buffer space, wherein
• the coating material feeder includes:
• a coating material discharge region positioned in the hole portion;
• and
• a coating material guide region positioned outside the hole portion and guiding the coating material in the coating material tank toward the coating material discharge region,
• an upper peripheral groove recessed from an outer peripheral surface toward an inside in a feeder radial direction as a radial direction of the coating material feeder, facing an inner peripheral surface of the hole portion, and allowing the coating material to flow in is formed of resin in the coating material discharge region,
• the upper peripheral groove extends in the longitudinal direction and a plurality of the upper peripheral grooves are formed at intervals in a feeder circumferential direction as a circumferential direction of the coating material feeder, and
• a lateral groove interconnecting the upper peripheral grooves adjacent to each other in the feeder circumferential direction and intersecting the upper peripheral grooves is further formed in the coating material feeder.
