Cap heat-sealing apparatus for containers |
摘要 |
A cap heat-sealing apparatus for containers comprises a stationary pressing member (18), and movable pressing members (19) arranged around the stationary pressing member (18) and identical in number to the number of corners of a container opening fitting portion (8) of a polygonal cap (5) formed at its periphery for heat sealing. The stationary pressing member (18) has an outer periphery shaped in conformity with the shape of the inner periphery of the fitting portion (8). Each of the movable pressing members (19) is movable toward or away from the stationary pressing member (18) in a horizontal direction through the center of the stationary pressing member (18) and the corner thereof opposed to the movable pressing member (19). Each movable pressing member (19) has a pressing face V-shaped when seen from above to conform with an outer peripheral portion of the stationary pressing member (18) including one corner thereof so that when the movable pressing members (19) are brought toward the stationary pressing member (18), the pressing faces thereof are combined to conform with the entire outer periphery of the member (18). |
