摘要： A cap heat-sealing apparatus for paper containers comprises a vertically movable head, a fixed pressing member provided on the bottom surface of the head, a pair of divided movable pressing members arranged around the fixed pressing member and connected to the head so as to be horizontally movable toward or away from the fixed pressing member, and a heating high-frequency coil attached to the head and surrounding the fixed pressing member. The fixed pressing member has an outer perophery shaped to position along the inner surfaces of heat-sealing container opening edge fitting portions of inverted V-shaped cross section formed at the outer periphery of a square paper cap, which has an aluminum foil layer. The movable pressing members have an inner periphery shaped to position along the outer surfaces of the fitting portions. The high-frequency coil is spaced apart from the fixed pressing member by a clearance for the fitting portions to enter.
