Abstract
A method of forming a blowback cavity in a vial or similar cylindrical article comprises the steps of providing a cylindrical glass preform having a necked region and first forming an open blowback cavity adjacent the necked region and a relatively thin axially projecting terminal lip on the adjacent end of the preform and subsequently turning the terminal lip inwardly to form a radially extending face defining a mouth opening having a diameter smaller than the diameter of the blowback cavity.
