Method of sealing an article via radio frequency

摘要

A method of radio frequency sealing attaches a seal member to a cylindrical, hollow, access port of a container. The method uses two sets of spaced apart die elements to generate an axial electric field along a region where the port and seal member overlap. An external peripheral ring is formed about an exterior surface of the port. The method can be used with containers having a sealed periphery as well as those previously filled with a fluid.
