Abstract: A method for making a crystallized bottleneck of a polyester beer bottle is provided. The bottleneck has no machined screw threads and a length of 0.5-35 mm. To manufacture the crystallized bottleneck, an uncrystallized blank of the bottle is placed in an air-condition environment and a crystallizer is preheated before crystallization. A bunker is loaded with the uncrystallized blank, which is delivered to a blank horse's head via a conveyor belt. A bottleneck portion of uncrystallized bottle blank is then sent into a crystallizer to heat it at high temperature and crystallize it via an arbor transmission chain. The polyester bottle blank having a crystallized bottleneck portion is discharged through output blank horse's head and delivered to another conveyor belt to cool and shape it.

Abstract: A polyester beer bottle comprising a bottleneck, a body and a bottom of the bottle, which are once blown and shaped with polyester blank, in which arc portion in a vertical section extended from the joint of shaped bottom and body of the bottle to a plane of the bottom has a radius ranging over 15-25 mm; an arc radius in a vertical section of the concave quaquversal portion projecting inwards at a bottom surface of said bottle is in a range of 20-35 mm, and the distance between a top of the concave quaquversal portion to the plane of bottom is in a range of 7-15 mm; an outward projecting support flange portion is formed at the joint between said concave quaquversal portion and the bottom plane of the bottle, a height of the flange portion is in a range of 0.

Abstract: A crystallized bottleneck of a polyester beer bottle, in which the crystallized bottleneck has no machined screw thread and where the bottleneck has a crystallized length of 0.5-35 mm. To manufacture the crystallized bottleneck, an uncrystallized blank of the bottle is placed for 24-72 hours in an air-conditioned environment and a crystallizer is preheated two hours or more before crystallization. A bunker is loaded with the uncrystallized blank, which is delivered to a blank horse's head via a conveyor belt, then a bottleneck portion of the uncrystallized bottle blank is sent into a crystallizer to heat it at high temperature and crystallize it via a arbor transmission chain; at the same time, the uncrystallized portion of the blank body is controlled, so that it is not affected by the environment at high temperature. The polyester bottle blank having a crystallized bottleneck portion is discharged through an output blank horse's head and delivered to another conveyor belt to cool and shape it.
