Abstract
A blow mold for use with the blow pin assembly having article body, neck, and finish defining portions including an anvil portion to permit severing of a flash portion of the parison from the article. A shearing ring portion cooperates with the anvil portion to sever the flash portion of the parison from the article and both portions are inclined with respect to a plane normal to the axis of reciprocation of the blow pin to form an inclined finish on the article. A tip portion has an outer surface cooperating with the finish defining portion to calibrate the thickness of the article between the neck and anvil portions.
