ABSTRACT:
A pair of plastic containers are compressed intermediate a pair of jaws and RF energy is applied as a function of the change in impedance of the melting plastic between the jaws to sterilize with heat the plastic intermediate the pair of jaws and to form a sterile rupturable membrane encircled by a seal to permit fluid communication on demand between the containers upon rupture of the membrane. The use of RF energy to heat bipolar plastic material (dielectric material) both sterilizes the plastic material and welds the plastic material at a proper temperature to form the rupturable membrane without the use of any instrumentation indicative of temperature or other control parameters.
