    摘要： A method for manufacturing a glass container includes the steps of (a) providing a plunger (1) coated with a ceramic coating (3) or a sprayed metal coating (2) of self-fluxing alloy or both coatings on at least one portion of a surface of the plunger and (b) forming a lubrication carbon layer on surfaces of molds including a blank mold and a neck ring by periodically injecting (14) flames of at least one kind of gaseous hydrocarbon having a carbon to hydrogen ratio more than 0.75. The coating of the plunger (1) prevents the plunger from being oxidized so that flaking of an oxidized layer which will be accompanied by generation of defects at an inside surface of a glass container does not occur. Due to the carbon layer formed through flame injection of hydrocarbons, oiling of the molds is unnecessary and generation of bubbles in the oil film does not occur. This method not only increases the impact strength of a glass container but also increases the uniformity of impact strength.
