Definitions
- TITLE "Installation for the manufacture of receptacles comprising a sterile transfer zone"
- the invention relates to an installation for mass production of containers by forming preforms of thermoplastic material, the preforms and the containers being denoted indifferently by the terms "hollow body", the manufacturing installation comprising:
- a device for sterilizing the preforms which is arranged upstream of the forming station according to the direction of movement of the hollow bodies; - a device for transporting hot preforms in line along a first transfer path from the output of the heating station to a loading point of the forming station
- the invention is intended to be implemented in an installation for manufacturing containers of thermoplastic material and in particular of polyethylene terephthalate (PET) by forming, in particular by blow molding or stretch blow molding, of preforms.
- PET polyethylene terephthalate
- Such an installation makes it possible to produce containers in very large series at very high rates.
- the terms “hollow body” will be used interchangeably with the preforms or the containers formed from the preforms.
- the preforms are generally manufactured by injection at a first location and are blow molded to the final shape of the container at a second location on the manufacturing facility.
- Such a technology makes it possible to carry out the blow molding operation as close as possible to the place of filling, the injection operation being able to be carried out at any place. Indeed, it is relatively easy and inexpensive to transport preforms of reduced size, while transporting containers after blowing has the drawback. to be economically unprofitable because of their very large volume.
- the manufacturing installation comprises a heating station which makes it possible to heat the body of the preforms to the temperature required to carry out the forming step.
- the preforms thus heated are then conveyed to a forming station of the manufacturing facility.
- the hot preforms are deposited automatically in mold cavities by grippers such as grippers.
- a pressurized forming fluid is injected into the preforms to press the wall of the preform against the walls of the cavity to conform the preform to the final container.
- This forming operation is generally accompanied by a stretching operation consisting in introducing an elongation rod into the preform through its body in order to axially stretch the wall of the preform.
- the containers are generally filled immediately after forming.
- the filling station and the blowing station are juxtaposed to obtain a production installation which is compact and carries out the entire production process of the containers, until the containers are filled.
- the aim is to reduce by all means the risks of contamination of the containers, which containers are moreover capable of being filled with products more or less sensitive to such risks.
- the container filling operation is usually recognized as being the most sensitive with regard to the risks of contamination. Before transporting a container to the filling station, the container must therefore be sterilized.
- a sterilizing agent such as hydrogen peroxide (H202) in a container or in a preform before entering the filling station.
- H202 hydrogen peroxide
- a sterilizing agent such as hydrogen peroxide is particularly effective when heated.
- the forming of the containers is carried out by blowing a sterile gas, such as air, into the preforms.
- the containers introduced into the filling station are only one of the main vectors of contamination.
- pathogens as soon as they are present in the direct environment of the receptacles, from the air to the components of the installation, are in particular liable to contaminate the internal volume of the receptacle.
- the filling station is also chemically decontaminated, for example by spraying sterilizing solutions such as sodium hydroxide (NaOH) or hydrogen peroxide (H202).
- NaOH sodium hydroxide
- H202 hydrogen peroxide
- a filling enclosure In which the atmosphere is kept sterile by injecting sterile air.
- the filling enclosure thus contains a sterile atmosphere in excess pressure with respect to the immediate external environment of the filling enclosure. This guarantees that no contaminating element will be sucked in from the outside through interstices in the enclosure or even through the passage windows of the receptacles.
- the forming station in a sterile enclosure closed by walls, called a blowing enclosure, which is decontaminated and which contains a sterile atmosphere.
- the interior of the blowing enclosure is therefore supplied with sterile air, and the sterile atmosphere is maintained at an overpressure relative to the outside of the blowing enclosure.
- the blowing chamber has an internal pressure lower than that of the filling chamber, thus ensuring the sterility of the filling station.
- the jets of sterile gas are directed towards the interior of the hollow bodies, through their neck, to prevent any entry of stale air and to maintain a sterile atmosphere there.
- Such a device makes it possible to avoid contamination of the neck and of the interior of the hollow body during its movement. It is thus no longer necessary to maintain a perfectly sterile atmosphere in the blowing chamber.
- the forming station is generally in the form of a rotating carousel carrying forming stations at its periphery.
- the very rapid rotation of the carousel causes very significant air circulation.
- Laminar jets of sterile air are exposed to this mixing. They must be sufficiently powerful so that the flow remains laminar up to the neck of the hollow bodies.
- the production of sterile gas curtains therefore requires a large flow of sterile gas under pressure, which consumes a lot of energy.
- the laminar flow of the air jets emitted by the nozzles very quickly becomes turbulent after their passage along the necks of the hollow bodies.
- the sterile gas stream disperses and mixes with ambient air. As a result, the exterior of the body of the receptacles is even more exposed to the risks of contamination.
- the invention proposes an installation for mass production of containers by forming preforms of thermoplastic material, the preforms and the containers being denoted indifferently by the terms "hollow body", the manufacturing installation comprising:
- a device for sterilizing the preforms which is arranged upstream of the forming station according to the direction of movement of the hollow bodies;
- At least one source of emission of a flow of sterile gas which bathes the hollow bodies along their transfer paths characterized in that at least one transfer path is arranged in a transfer zone which is separated from a forming zone containing the forming station by a partition wall, said partition wall having at least one passage opening for hollow body.
- the first transfer path of the preforms and the second transfer path of the containers are arranged in the transfer zone which is separated from the forming zone by said partition wall, said partition wall comprising an opening for the passage of the preforms and a opening for passage of receptacles;
- the filling station is enclosed in a closed sterile enclosure, called a filling enclosure, the heating station and the forming station being arranged outside the filling enclosure, the filling enclosure comprising a window d 'entry of the containers coming directly from the transfer zone, a first flow of sterile gas leaving the filling chamber through the inlet window under the effect of a pressure difference between the filling chamber and the zoned transfer, the container transport device transporting the containers to the inlet window of the filling chamber;
- the manufacturing installation comprises a second closed sterile enclosure, called a transfer enclosure, a delimiting wall of which is formed by said separation wall, the transfer enclosure enclosing the transfer zone, the forming station being arranged at the 'outside the transfer chamber in the forming zone which has a pressure lower than the internal pressure of the transfer chamber, the internal pressure of the transfer chamber being lower than that of the filling chamber and the inlet window of the filling chamber opening directly into the transfer chamber;
- the container transfer path and the preform transfer path are arranged generally in alignment with the first sterile gas flow coming from the filling chamber, the preforms and the containers moving countercurrent to said first sterile gas flow ;
- the container transport device comprises at least one downstream rotary transfer wheel which allows the containers to be conveyed from inside the forming zone to the transfer zone via the container passage opening, the downstream wheel transfer device comprising at its periphery individual container holding members, a central part of the downstream transfer wheel being separated from the transfer zone by a casing comprising a passage groove for the holding members;
- the retaining members of the downstream transfer wheel grip each container directly in a mold of the forming station;
- the device for transporting the preforms comprises at least one upstream rotary transfer wheel which allows the preforms to be conveyed from the inside of the transfer zone to the inside of the forming zone via the opening for the passage of the preforms , the upstream transfer wheel comprising at its periphery individual preform holding members, a central part of the upstream transfer wheel being separated from the inside of the transfer zone by a casing comprising a passage groove for the holding members ;
- the retaining members of the upstream transfer wheel deposit each preform directly in a mold of the forming station;
- the heating station is arranged inside a third enclosure, called a heating enclosure, the internal pressure of which is lower than that of the transfer enclosure, the heating enclosure opening directly into the transfer enclosure by a passage of preforms, the passage of preforms being arranged substantially opposite the container inlet window in the direction of the first flow of sterile gas;
- the transfer enclosure is supplied directly with sterile gas by a second laminar flow of sterile gas which is directed vertically towards a neck of the hollow bodies.
- FIG. 1 is a top view which schematically represents an installation for manufacturing containers produced according to the teachings of the invention
- FIG. 2 is an axial sectional view which shows a preform capable of being taken up by the manufacturing installation of FIG. 1;
- Figure 3 is an axial sectional view which shows a container obtained from a preform by forming in a forming station of the installation of Figure 1;
- Figure 4 is an axial sectional view along the sectional plane 4-4 of Figure 1 which shows a preform received in a blowing station of the forming station;

- Figure 7 is a sectional view along the sectional plane 7-7 of Figure 1 which shows a container transported in the transfer enclosure and exposed to a flow of sterile laminar gas from a ceiling of the transfer enclosure.
- the term “enclosure” is defined as being a space physically closed by walls.
- FIG. 1 schematically shows an installation 10 for mass production of containers 12B made of thermoplastic material from preforms 12A.
- the terms “hollow body” will be used to denote indifferently a preform 12A, a finished container 12B, or a preform being formed.
- the containers 12B are here bottles.
- the thermoplastic material is here formed by polyethylene terephthalate, hereinafter referred to by its acronym “PET”.
- FIG. 2 shows an example of a preform 12A and in FIG. 3 an example of a container 12B obtained from said preform 12A.
