ABSTRACT:
An apparatus for forming a bond between a plastic fill spout and a plastic container immediately after forming a bore through the container, includes a tool with a bore forming platen at its leading edge, a trailing end platen at its opposite end, and an intermediate spacer of an insulative material for thermally isolating the bore forming and trailing end platens. A longitudinally reciprocable fixture supports the spout in a longitudinal orientation to move the spout toward and away from the container, and a second fixture supports the tool in axial alignment with the spout and for longitudinal movement toward and away from the container, with the bore forming platen nearest the container. The tool is moved against the container and the bore forming platen heated, then moved through the container wall to provide the bore. The trailing end platen is positioned against the container to heat a rim of the container surrounding the bore, and a lead end of the spout is moved against the trailing platen, whereupon the lead end and rim are heated and fused simultaneously. The tool and its supporting fixture can be withdrawn transversely to permit longitudinal movement of the spout into engagement with the rim portion immediately after heating. Subsequent cooling of the lead end and rim forms the bond.
