Abstract
An inductive cap sealer for sealing an inner seal over an opening in a 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 openings and the field focusing elements are spaced to allow cooling air to flow around the field focusing elements and past the coil.
