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 tack welds (34) are formed within recesses (44) that extend completely through the wall of the necked opening (14) and into the insert (18). 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), allowing tips (42) of ultrasonic transducers (36) to penetrate completely through the wall of the necked opening (14) and into the insert (18). The tack welds (34) fixedly attach the insert (18) to the necked opening (14). If the insert (18) and necked opening (14) structure is damaged, such as by dropping the package (10), failure occurs at the ultrasonic welds (34) allowing harmless venting of the pressure inside the package (10).
