Abstract
A package (10) includes a polyethylene terephthalate (PET) container (12) having a necked opening (14). A PET insert (18) is fixedly attached to an inside surface (30) of the necked opening (14) by a plurality of tack welds (34). The insert (18) makes a substantially line contact (32) with the inside surface (30) of the necked opening (14). The substantially line contact (32) extends continuously around the inside surface (30) of the necked opening (14) to form a fluid tight seal between the inside surface (30) of the necked opening (14) and the insert (18). To make the package (10), the insert (18) is driven into the necked opening (14). The tack welds (34) are formed between the necked opening (14) and the insert (18) by application of ultrasonic energy at the necked opening (14) below the line contact (32). The tack welds (34) fixedly attach the insert (18) to the necked opening (14).
