The attachment plate has a bank section formed thick at a peripheral edge, a base bottom section formed as a recess in a center, an inclined outflow hole opened inclinedly with respect to the base bottom section near the base bottom section center such that the solution flows out toward an attachment plate distal end direction, and a weir provided in an arcuate or crescent shape. A flow of the solution flowed out from the inclined outflow hole is reversed to flow backward by the weir. ## Claims ### Claim 1 An applicator for medical-use liquids that does not cause liquid leakage comprising: a handle section comprising a hollow cylindrical member, a liquid container incorporated in the cylindrical member, and a cleaver of the liquid container; and an applying section comprising an attachment plate of an application pad directly fixed to a lower end of the cylindrical member to be an inclined cross section, and the application pad fixed to the attachment plate, wherein the attachment plate is provided with a bank section which is formed thicker at a peripheral edge, a base bottom section formed as a recess in a center, only one inclined outflow hole penetrating the attachment plate, and opened inclinedly with respect to the base bottom section such that a solution released and discharged near the base bottom section center from the liquid container flows out toward an attachment plate distal end direction, and a weir provided in an arcuate shape or a crescent shape in the base bottom section in the attachment plate distal end direction from the inclined outflow hole, the inclined outflow hole being located on a center side of the arc, wherein the weir is independent and not linked with the bank section, and the weir being 0.1 to 1 mm higher than the bank section in a vertical direction with respect to an attachment plate upper surface on a basis of the attachment plate upper surface. ### Claim 2 (depends on 1) The applicator according to claim 1, wherein the cylindrical member is formed in a cylindrical shape having a taper that narrows downward. ### Claim 3 (depends on 1) The applicator according to claim 1, wherein the cleaver of the liquid container is an actuator sleeve inserted into the cylindrical member. ### Claim 4 (depends on 1) The applicator according to claim 1, wherein a center axis of the cylindrical member is inclined at 40 to 50° with respect to the attachment plate upper surface on a basis of the attachment plate upper surface. ### Claim 5 (depends on 1) The applicator according to claim 1, wherein the weir is 0.25 to 0.75 mm higher than the bank section. ### Claim 6 (depends on 1) The applicator according to claim 1, wherein the weir provided in an arcuate or a crescent shape is inclined at 40 to 50° in a direction further away from a center side of an arc toward an upper end of the weir on a basis of a base bottom section surface. ### Claim 7 (depends on 1) The applicator according to claim 1, wherein the weir is higher than the bank section in the vertical direction with respect to the attachment plate upper surface on a basis of the attachment plate upper surface, and a top section of the weir bites into the application pad. ### Claim 8 (depends on 1) The applicator according to claim 1, wherein the medical-use liquid is a liquid selected from povidone-iodine liquid, ethanol liquid, isopropanol liquid, potassium iodide liquid, benzalkonium chloride liquid, benzethonium chloride liquid, chlorhexidine gluconate liquid, glutaraldehyde liquid, and olanexidine [1-(3,4-dichlorobenzyl)-5-octylbiguanide] liquid, or a mixed liquid of two or more kinds of these. ### Claim 9 (depends on 1) The applicator according to claim 1, wherein the viscosity of the medical-use liquid is 0.5 to 15.0 mPa·s. ### Claim 10 (depends on 2) The applicator according to claim 2, wherein the cleaver of the liquid container is an actuator sleeve inserted into the cylindrical member. ### Claim 11 (depends on 10) The applicator according to claim 10, wherein the application pad and the attachment plate are formed in a substantially rice ball shape. ### Claim 12 (depends on 11) The applicator according to claim 11, wherein a center axis of the cylindrical member is inclined at 40 to 50° with respect to the attachment plate upper surface on a basis of the attachment plate upper surface. ### Claim 13 (depends on 12) The applicator according to claim 12, wherein the weir provided in an arcuate or a crescent shape is inclined at 40 to 50° in a direction further away from a center side of an arc toward an upper end of the weir on a basis of a base bottom section surface. ### Claim 14 (depends on 13) The applicator according to claim 13, wherein the weir is higher than the bank section in a vertical direction with respect to the attachment plate upper surface on a basis of the attachment plate upper surface, and a top section of the weir bites into the application pad. ### Claim 15 (depends on 14) The applicator according to claim 14, wherein the medical-use liquid is a liquid selected from povidone-iodine liquid, ethanol liquid, isopropanol liquid, potassium iodide liquid, benzalkonium chloride liquid, benzethonium chloride liquid, chlorhexidine gluconate liquid, glutaraldehyde liquid, and olanexidine [1-(3,4-dichlorobenzyl)-5-octylbiguanide] liquid, or a mixed liquid of two or more kinds of these. ### Claim 16 (depends on 15) The applicator according to claim 15, wherein the viscosity of the medical-use liquid is 0.5 to 15.0 mPa·s. ### Claim 17 (depends on 2) The applicator according to claim 2, wherein the weir provided in an arcuate or a crescent shape is inclined at 40 to 50° in a direction further away from a center side of an arc toward an upper end of the weir on a basis of a base bottom section surface.
