Abstract
An inductive cap sealer () for sealing an inner seal over an opening () in container () includes a vented sealing head (). The sealing head () contains an induction coil () for producing an electromagnetic field when energized by a power supply. Field focusing elements () contain the coil () and direct the electromagnetic field to a sealing region beneath the sealing head (). The housing () has a central inlet vent () flanked by two outlet vents () aligned with a vent plate () inside the housing () having a plurality of small openings () which allow a fan () to blow cooling air through the sealing head from only one side of the sealing head () in a generally U-shaped flow pattern, preferably from the side opposite the sealing region. The field focusing elements () are spaced to allow the cooling air to flow around the field focusing elements () and past the coil ().
