Abstract: The invention relates to a method for decontaminating a preform made of thermoplastic material by exposing at least part of the preform to reactive species obtained by mixing a precursor agent with a plasma, the plasma being generated by injection of a carrier gas into a reactor, the method including mixing of the precursor agent with the plasma is carried out exclusively outside the reactor before it is in contact with the preform. The invention also relates to a decontamination device for carrying out the method.

Abstract: A process for regulating a cyclical production of containers by stretch blow molding from preforms, comprising an initializing phase, a regulated production phase, and a stabilizing phase. In the regulated production phase, the preblowing curve is measured and stored, and a real instant and/or a real pressure is calculated, corresponding to a characteristic point. A new value of at least one operating parameter of the machine is calculated as a function of a difference between a real instant and a reference instant and/or between a real pressure and a reference pressure. The regulated production phase monitors for change, imposed by the operator, of a value of an operating parameter of the machine and automatically updates the regulating parameters in the stabilizing phase while production is continued. The process also corrects the reference instant and/or the reference pressure as a function of the real pressure and/or real instant values stored.

The standing plane also has an arched area extending from the seating surface as far as a central zone of the bottom, the arched area delimiting a concavity oriented toward the outside of the container.

Abstract: The present invention relates to an installation for manufacturing containers made of thermoplastic material, having a sterilizing mode and a production mode. The installation comprising a molding machine, a transfer means, and a decontamination device. The molding machine is equipped with at least one molding device having stretching means, and the molding device is designed to manufacture by stretch blow molding said containers from preforms when the installation is in production mode. The transfer means conveys the manufactured containers between the molding machine and a second downstream machine when the installation is in production mode. The decontamination device introduces the sterilizing agent into at least one sterilizing preform during the sterilizing mode. The installation further comprises removal means that can be actuated in sterilizing mode to remove the hollow bodies from the transfer means upstream from the second machine.

The mobile element comprises a mobile magnetic dipole, and the fixed element comprises a fixed magnetic dipole, the fixed magnetic dipole applying a magnetic force from a distance to the mobile magnetic dipole in order to force the mobile element toward one or other of its two stable extreme positions.

Abstract: The present invention relates to a method for bundle-packaging batches of products, wherein products are moved in a longitudinal running direction, grouped into batches and wrapped with a film of heat-shrinkable film. Each wrapped batch is heated to form a contraction of each sheet around said batch. Heating of a batch is performed by the circulation of at least one heated air stream and by the expulsion of said stream toward the interior of the enclosure of an oven provided, successively, with first and second sections; the sheet is cooled; during heating, along at least a part of the first section, a first air stream is shaped discontinuously and expelled toward the interior of said enclosure. The method consists, during heating, along said second section, in shaping a second stream as an air knife and expelling said air knife toward said sheet to be smoothed.

Abstract: A method for regulation of the angular position of hollow bodies in an installation for production of containers. The hollow bodies are moved by individual support members each of which is equipped with means for causing the hollow body to turn about its axis. The method includes a first step of measuring an angular offset of at least one particular hollow body relative to a reference angular position in a measurement zone. The method also includes a second step of compensating of the angular position of the subsequent hollow bodies in a compensation zone upstream of said measurement zone as a function of the angular offset measured for the at least one particular hollow body.

Abstract: A sterilization machine for the sterilization of caps, comprising an isolation chamber having an inner space in which the caps are advanced along a conveying path and separating the inner space from an outer space, a plurality of carts positioned within the inner space and an actuation unit arranged in the outer space and configured to selectively advance the carts along an advancement path by means of the generation of an electromagnetic field.
