Method of formation by blowing, of hollow articles such as bottles, of plastic material. Two mold halves are constructed and arranged so that, when brought together they conjointly define the shape of the article to be blown and form an axially disposed mass of hot plastic. A blowing passageway in one of the halves or in one of the halves of a contiguous pair, is in communication with the aforesaid mass. When pressure fluid is applied it forces its way axially through the mass, into the enclosed parison and expands it to the shape of the mold. |
