Abstract: A method for treating a polymer vessel, comprising treating a surface region of the vessel by exposing the surface region to a high-frequency plasma; and coating the surface region of the vessel with a lasting water-based edible coating. A vessel treated in accordance with the method. The method may include placing the vessel on a conveyor, a robotic arm or system to facilitate the movement of the vessel through the high-frequency plasma device. Including rotating the vessel to treat different parts thereof.

Abstract: 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.

Abstract: A cup having a rim and candy coating disposed about the rim. The coating has a flavored layer applied to the rim as a liquid having an acid component, sugar, and flavoring, and a sugar crystal layer applied to the flavored layer before it hardens. The cup may include a projection extending radially into the cup's interior. The projection includes a support surface for supporting a portion of a like cup inserted into the cup's interior and determining a depth of insertion of the like cup into the cup. The cup may include a plurality of spaced apart spacer projections extending radially into the interior of the cup, abutting the sidewall of the like cup inserted into the cup's interior, and thereby spacing the coating of the cup from the sidewall of the like cup. A method of and device for manufacturing the cup are also provided.

Abstract: A cup is provided for containing a liquid medicine. The cup includes a wall with a candy coated rim portion. The coating includes a mixture of sugar, water and agar, and a layer of flavored and/or colored powdered sugar. A plurality of inwardly extending spacer ribs are spaced around the wall of the cup. The spacer ribs preferably have a generally triangular shape. The cup is made by orienting the cup in an upside down position; dipping the cup into a heated liquid mixture of sugar, water and agar to coat the rim portion of the cup; removing the cup; allowing the liquid on the rim portion to partially cool to a tacky consistency; applying powdered sugar to the tacky liquid, and allowing the coating to completely cool. A tray is provided for holding a plurality of cups. The tray includes a bottom with a plurality of spaced, substantially upside down cup-shaped bosses projecting upwardly from the tray bottom. Each of the bosses includes a reinforced side wall. The tray has a reinforced peripheral wall.
