Applicator

A method of treating tinea unguium by using an applicator for applying a solution for treating tinea unguium to an affected part of a patient, wherein

• the applicator comprises a solution container having an opening, a bottomed tubular holder, and a columnar brush member comprising synthetic fibers,
• the bottomed tubular holder having a tubular body and a bottom portion is provided between the solution container and the columnar brush member,
• the bottom portion of the bottomed tubular holder has at least one pore and the solution enters the bottomed tubular holder via said at least one pore,
• the amount of a solution that moves from the solution container to the bottomed tubular holder is controlled by the at least one pore provided at the bottom portion of the bottomed tubular holder, and
• the columnar brush member is inserted inside of the tubular body of the bottomed tubular holder, wherein
• the applicator is retained with the columnar brush member facing downward, and a solution placed inside the solution container enters the bottomed tubular holder via the at least one pore provided at the bottom portion of the bottomed tubular holder to reach an end face of the columnar brush member, and
• a capillary is formed as a gap for supplying the solution between the synthetic fibers inside the columnar brush member from an end face of the columnar brush member to the tip portion opposite to the end face of the columnar brush member by capillarity thereof.

A method of treating tinea unguium by using an applicator for applying a solution for treating tinea unguium to an affected part of a patient, wherein

• the applicator comprises a solution container having a neck portion, which is provided with a circular opening, and a columnar brush member obtained by impregnating a bundle of synthetic fibers with an adhesive and then grinding the bundle of synthetic fibers, wherein
• the columnar brush member is disposed at the opening of the solution container, and
• a tip portion of the columnar brush member outside the solution container is a brush and has a fan shape extending in a perpendicular lateral direction against a vertical longitudinal direction, and a thickness of the fan-shaped tip portion of the columnar brush member decreases in a perpendicular lengthwise direction against the vertical longitudinal direction toward the tip portion of the columnar brush member, wherein
• the perpendicular lateral direction and the perpendicular lengthwise direction are directions orthogonal to each other on a plane perpendicular to the vertical longitudinal direction, and a capillary is formed as a gap for supplying a solution between the synthetic fibers inside the columnar brush member from that has reached end face of the columnar brush member reaches to the tip portion opposite to the end face of the columnar brush member by capillarity thereof,
• wherein the columnar brush member is formed by bundling synthetic fibers 7 to 50 μmin diameter so that the density ranges from 0.15 to 0.65, wherein the density is the rate of synthetic fibers per sectional area to an adhesive gluing the same, with a cross section cut perpendicular to the vertical longitudinal direction of the columnar brush member,
• a bottomed tubular holder having a tubular body and a bottom portion is provided between the solution container and the columnar brush member,
• the bottomed tubular holder comprises a supporting member inside said holder, the bottomed tubular holder is inserted into the opening of the solution container,
• the bottom portion of the bottomed tubular holder has at least one pore and the solution enters the bottomed tubular holder via said at least one pore, and
• the columnar brush member is inserted inside of the tubular body of the bottomed tubular holder, wherein
• the applicator is retained with the columnar brush member facing downward, and a solution placed inside the solution container enters the bottomed tubular holder via the at least one pore provided at the bottom portion of the bottomed tubular holder to reach an end face of the columnar brush member.
