Method for the production of a series of containers comprising a step for marking containers

A method for producing a series of individual containers (2) from a series of preforms (4)

• made of plastic materials that are heated in a container production facility (1) that comprises at least one heating station (6) for heating the series of preforms (4), a forming machine (8) that comprises a plurality of forming stations (24), one or more treatment machines (34) that each comprise a plurality of treatment stations (36), with the method comprising the following steps:
• circulating the series of preforms (2) in the heating station (6) up to the forming machine during which each preform (4) is held individually and heated at a reference temperature,
• forming of the series of preforms (4) in the forming machine (8), each heated preform (4) being placed in one of the plurality of forming stations (24) in which said preform (4) is formed into a container (2), in such a way that said series of preforms (4) is formed into the series of individual containers (2),
• treating the series of individual containers (2) in the one or more treatment machines (34, 10, 46), with each individual container (2) being placed in one of the plurality of treatment stations (36, 40, 48),
• circulating each container that is held individually between the forming machine and the one or more treatment machine(s);
• and
• Wherein the method further comprises a phase for individual identification of each container that is produced during a predetermined tracking period, the individual identification phase comprising a marking step during which each individual container (2) that is produced during said tracking period receives a marking that matches said container, to allow individual identification of said container by distinguishing said container from all of the other containers produced by the production facility during said tracking period.
