A method of manufacturing a dosage cup, comprising the steps of: creating a flavored layer mixture sterilizing the dosage cup by at least one ozone sterilization device coating the rim of the dosage cup with the flavored layer mixture to form a flavored layer disposed thereon and coating the flavored layer with sugar crystals. The ozone sterilization device emits a high-voltage charge to the rim of the cup at an angle in the range of about 0.5 degrees to about 45 degrees. The method may include placing the cup on a conveyor to facilitate the movement of the cup through the high-voltage discharges of the ozone sterilization devices.
