Embodiment Construction

[0023] in the attached figure 1 A longitudinal section of a parison 10 into which a stretching rod 11 has been introduced is shown in . The stretching rod 11 serves to at least temporarily guide and stretch the parison 10 during its transformation into a container. Typically, contact between the free end 12 of the stretch rod 11 and the bottom 13 of the parison 10 is achieved first. A longitudinal stretching of the parison 10 occurs during further insertion of the stretch rod 11 into the parison 10 . After completion of the stretching process or already during the execution of the stretching process, a filler 15 is introduced into the parison 10 via a filling valve 14 through a liquid channel 16 surrounding the stretching rod 11 . The liquid flow can be controlled by filling valve 14 .

[0024] This liquid channel 16 , which surrounds the stretch rod 11 in the form of an annular channel, has an outlet opening 17 which can be placed on the mouth 18 of the parison 10 . A sea...

Abstract

The invention relates to a molding and filling station of a system for manufacturing filled containers from preforms (10) by means of liquid filling material (15) introduced into the preform (10) under pressure, said molding and filling station comprising a stretch rod (11) and a liquid duct (16) which can be controlled by means of a filling valve (14), surrounds at least part of the stretch rod (11) and ends in at least one outlet opening (17) that can be placed on the orifice (18) of the preform (10), the molding and filling station being characterized in that a gas barrier (20) is located in the liquid duct (16) between the filling valve (14) and the outlet opening (17).

Description

technical field [0001] The invention relates to a forming and filling station of a plant for producing filled containers from thermally conditioned parisons by means of a liquid filler introduced into the parisons under pressure. Background technique [0002] Conventionally, containers, in particular bottles, are formed in a blow molding process by molding gas flowing under pressure into preheated parisons and filled in a second step with a filler, in particular a liquid filler. [0003] The newly developed optimization method assumes that preheated parisons can be formed and filled in one step not with pressurized gas but with a liquid filler supplied under pressure. Such a method is known, for example, from DE 10 2010 007 541 A1. [0004] In order to be able to transform the parison into a container, the parison is then thermally conditioned, that is to say in particular heated and provided with a suitable temperature profile. Here, the body of the parison is heated, for...
