Abstract
A port is formed in a thermoplastic container wall by slitting the wall, inserting a thermoplastic tube through the slit, placing a mandrel in the tube, placing opposed dies defining a bore over the sheet and tube, and dielectrically heating the thermoplastic to fuse the tube and sheet. Preferably the bore defined by the dies is of a diameter slightly less than that of the tube, and has an enlarged central area which forms a thickened section of material over the slit.
