Definitions
- the invention relates to the field of the sterilization of caps or collars of containers.
- the invention relates to a method and a system for decontaminating corks or container necks for optimally treating all the surfaces of these plugs or necks.
- Containers such as tubes, jars, flasks, cardboard food bricks or PET bottles (polyethylene terephthalate) are most often intended to contain common consumer products, for example beverages, pharmaceuticals or cosmetics.
- Containers, such as bottles (especially PET) are typically obtained via a stretch blow molding process from blanks, for example preforms or intermediate containers having previously already undergone a first forming operation. The blanks and caps of the containers are initially stored in a non-sterile environment.
- Cardboard food bricks have a closure device, consisting of an attached collar, closed by a cap.
- the manufacture of a brick generally comprises a collar gluing step at an opening on one side of the brick.
- these bricks, their necks, and the caps that are intended for them are also initially arranged in a non-sterile environment. Therefore, before filling and closing the containers, the latter, their necks and their plugs must first undergo a decontamination process in a sterilization chamber.
- a known solution is to spray a sterilizing agent on the internal surfaces of the plugs, necks and containers, for example hydrogen peroxide (H 2 O 2 ) and cause its evaporation by thermal action.
- a sterilizing agent for example hydrogen peroxide (H 2 O 2 ) and cause its evaporation by thermal action.
- H 2 O 2 hydrogen peroxide
- Such a solution requires spraying the agent on all the surfaces of the containers, necks and plugs, however some surfaces are difficult to reach.
- the containers / collars / plugs must be exposed to the agent for a predetermined time at a time sufficiently long to ensure effective sterilization, but also short enough to limit any damage by heating, potentially damaging these surfaces.
- a rinsing step to ensure that any trace of the product has been eliminated.
- Such a solution involves longer processing times and is complex to implement.
- the document JPH06142165 proposes to irradiate with a low energy electron beam an object of complex shape, such as a plug. Accelerated electrons form this electron beam, some of which collide with gas molecules of the irradiated medium, thus generating scattered electrons. After propagation, the electron beam, composed of direct and scattered electrons, then reaches the surfaces of the object and sterilizes them. The irradiated surfaces of the object also induce reflected and / or secondary electrons to sterilize surfaces that are not directly irradiated.
- a low energy beam involves a beam current (that is to say, anode current) of low value, usually of the order of ten mA. Since these current values are small, the quantity of accelerated electrons is limited, as are their penetration into the material (a few m) and their backscattering. To ensure the complete elimination of any microorganism, a minimum dose of electrons must be produced. Therefore, in order to deposit a sufficient lethal dose of electrons on the surface of the object to be treated, generally of the order of ten kGy, a treatment time of several seconds is commonly required.
- the treatment time of an irradiated object is a parameter particularly critical. Indeed, a prolonged exposure time of an object to an electronic radiation may cause undesirable effects on the object, namely discoloration, degradation, crosslinking phenomena, or migrations of odors.
- the solutions of the state of the art can only partially limit these problems.
- An object of the present invention is to overcome all the aforementioned drawbacks.
- Another object of the present invention is to treat all the surfaces of plugs or collars of containers with complex shapes, having areas that can not be treated directly by an incident electron beam.
- Another object of the present invention is to reduce the decontamination time of plugs or necks of containers with complex shapes, while improving the treatment efficiency, that is to say the rate of bacteriological reduction, on the surfaces. of these stoppers or collars of containers.
- each plug comprising a roof, a body projecting from a peripheral edge of the roof, this body having an opening opposite the roof, ribs projecting from an inner face of the body and / or an inner face of the roof, each collar comprising ribs and an opening, the ribs having zones of shadow, this method comprising:
- the bombardment being effected by means of a pulsed electric field comprising a series of electrical pulses of predetermined frequency, duration and intensity so as to obtain primary electrons and backscattered electrons, respectively allowing the decontamination of apparent areas and shadows of corks or passes.
- the frequency is in a range between 50 and 500 Hertz
- the frequency of the electrical pulses is 100 Hertz
- the duration of the electrical pulses is in a range between 5 and 250 nanoseconds
- the duration of the electrical pulses is 10 nanoseconds
- the intensity of the electrical pulses is between 1 and 20 kiloamperes
- the intensity of the electrical pulses is 5 kiloamperes.
- each plug comprising a roof, a body projecting from a peripheral edge of the roof, this body having an opening to the opposite the roof, ribs projecting from an inner face of the body and / or an inner face of the roof, each collar comprising ribs and an opening, the ribs having shaded areas, this system comprising :

- FIG. 4 illustrates a cross-sectional view of a container stopper, as well as the different electron paths resulting from a pulsed electron beam;
- FIG. 5 illustrates a sectional view of a container neck, and the different electron trajectories from a pulsed electron beam.
- FIG. 1 a system 1 comprising an electron gun, for generating a high intensity electron flow.
- the flow of electrons generated at the outlet of this gun is a flow / electron beam pulsed, for bombarding plugs 2 and / or collars of containers for their decontamination.
- plugs 2 Scroll with the aid of a transport device 3 in a sterilization chamber 4, that is to say a closed and sterile enclosure comprising the pulsed electron gun.
- Scrolling means here a continuous temporal transport.
- the plugs 2 are positioned in the sterilization chamber 3 sequentially, that is to say step by step, for example via the transport device 3. The realization of all of these elements is described in detail later.
- FIG 2 is an enlarged detail of the zone II shown in Figure 1.
- This figure shows the plugs 2 of the containers, the transport device 3 and the sterilization chamber 4 previously mentioned.
- the flow / electron beam at the barrel outlet is formed by a set of electrons, the latter being accelerated via the application of a potential difference between two electrodes, respectively a cathode and anode.
- the cathode is disposed in a closed space 5, for example an enclosure under "vacuum", that is to say at a pressure of very low value, for example less than 10 "5 bar, provided by a pumping device.
- the creation of such a vacuum prevents the potential collision of the electrons with gas molecules, thus risking generating for these electrons a loss of energy.
- the pumping device is connected to the closed space via a pipe 6.
- the anode is one of the outer faces of the vacuum sealed space.
- the electron flow can be emitted, for example in the direction of the anode by an explosive emission cathode, this cathode and the anode constituting a diode.
- the cathode with explosive emission constitutive of the diode can by way of non-limiting examples be made of graphite, stainless steel, copper, carbon or any other known material for the realization of this type of electrode.
- this cathode does not include a filament.
- an explosive-emitting cathode diode has the advantages of:
- FIG. 3 is a cross-sectional view of FIG. 2. This figure shows the stoppers 2 of containers, the transport device 3, the sterilization chamber 4, as well as the anode 7 ensuring both closure and therefore insulation, vacuum space and the formation of an electron bombardment window.
- the anode 7 is disposed downstream from the cathode in the direction of movement of the electrons and made in the form of a block of conductive metal, for example copper.
- the latter In order to let accelerated electrons pass into the atmosphere, the latter is pierced at its center and covered with a thin metal foil 9, typically of a thickness of the order of a few tens of ⁇ m, which can for example be realized in titanium or aluminum.
- the thickness of the metal sheet 9 is chosen so as to seal the vacuum between the cathode and the anode 7, while allowing the accelerated electrons from the cathode, and impacting this sheet to pass through.
- the anode 7 thus produced constitutes an electron bombardment window 8 allowing the accelerated electrons to pass between the vacuum 10 of the closed space and an external medium 11, for example gaseous, such as the ambient air.
- an external medium for example gaseous, such as the ambient air.
- the manner in which the conductive metal block of the anode 7 is pierced conditions the shape of the electron beam which passes through the surface of the metal foil 9 of the anode 7.
- the shape of the electron beam and therefore the opening of the window 8 electron bombardment can be chosen according to different geometries, by way of non-limiting examples in rectangular, circular or annular.
- FIG. 3 illustrates an opening, and therefore a rectangular window 8.
- the sheet 9 of the electron bombardment window 8 does not yield under the pressure difference between the vacuum 10 and the external medium 11 (relative for example to the external atmospheric pressure):
- the surface of the anode 7 can be made in a curved manner towards the inside of the vacuum-sealed space 10.
- the sheet 9 covering the anode 7 must be kept at a sufficiently low temperature, by means of the installation of appropriate cooling means, not shown.
- the anode 7 may for example be designed to include heat dissipation zones, or be cooled by circulating along the latter a cooling fluid through channels.
- the electron beam obtained at the output of the electron gun is sufficiently homogeneous to treat all of the apparent surfaces of the object to be treated.
- the surface of the electron bombardment window 8 is sized to cover a surface substantially greater than the apparent surface of the bottom of a plug 2 centered with respect to this window 8.
- the electron gun further comprises supply means for establishing a potential difference between the anode 7 and the cathode, in order to accelerate the electrons emitted by the cathode.
- the cathode is for example powered by a source of electrical energy (not shown) while the anode 7 is connected to ground.
- a continuous electrical energy source in order to generate a stream of electrons pulsed at the output of the electron gun, will be used, for example a high voltage power supply coupled to means for storing the electrical energy. for example a capacitive or inductive storage.
- a Tesla transformer is used coupled to a PFL (English acronym for "Puise Forming Line") shaping line, or any other power conditioning device, for example a Marx generator.
- a switch makes it possible to control the pulse duration (pulsing) of the electrical energy of the beam, stored during a charging period of the electron gun.
- This switch is coupled to a conductor, disposed in an insulation sheath.
- the conductor in its insulating sheath relates to the curved portion 12 of the system 1.
- the conductor is connected to the cathode of the diode of the electron gun, and provides the connection between the cathode and the transformer, via the switch, thereby supplying the diode with a pulsed voltage.
- a potential difference is thus created between the cathode and the anode 7, allowing the acceleration of the electrons emitted by the cathode in the vacuum 10.
- a pulsed electron flow of high intensity is obtained.
- a pulsed mode coupled with a low energy electron beam (less than 1 MeV) makes it possible, as opposed to a continuous mode, to reduce the electrical insulation stresses of the electron gun and to reduce therefore its bulk.
- effective electrical insulation of the transformer and the conductor is performed via oil insulation, and shielding steel or lead thin.
- the pulsed electron beam obtained at the output of the electron gun is used to bombard plugs 2 of containers of complex shapes thus allowing their decontamination of any microorganism.
- plug of complex shape is understood here to mean any plug having shaded areas, that is to say zones that can not be reached directly by incident scattered electrons.
- the electrons obtained at the output of the electron gun are diffused in air (external medium 11) and the plugs 2 treated in the same medium.
- air external medium 11
- plugs 2 treated in the same medium.
- any other gaseous or vacuum medium may be used for electron scattering and decontamination of plugs 2.
- plugs 2 of complex shapes are brought into a sterilization chamber 4, facing the electronic bombardment window 8, the opening of the plugs being turned towards this window.
- sterilization a closed, hermetic and sterile space including means of sterilization / decontamination.
- this chamber 4 is made using insulating metal surfaces 13 (eg lead, steel) constituting a cylindrical volume whose axis of revolution is centered around the anode 7. This volume is pierced so as to comprise an inlet opening 14 and an outlet opening 15 through which the device 3 for transporting plugs 2, thus allowing their routing under the electronic bombardment window 8 formed by the anode 7.
- the sterilization chamber 4 is thus, in this embodiment, constituent of the system 1 comprising an electron gun.
- the sterilization chamber 4 is independent of the system comprising an electron gun and comprises in its interior part or all of this system 1.
- the plugs 2 scroll laterally and in a single direction, parallel to and downstream of the window 8 of electron bombardment of the anode 7.
- the arrow 16 indicates by way of example a direction of lateral scrolling of the plugs 2.
- the plugs 2 are joined to each other, and scroll according to a predetermined transport path and speed, thanks to a preset transport device 3, here a set of rails on which slide the plugs 2.
- the plugs 2 can scroll along these rails under the effect of gravity or using mechanical means (wheels, pushers) or pneumatic (guns).
- such a rail system makes it possible to guarantee that the opening of the plugs 2 of the receptacles is turned towards the electron bombardment window 8 of the electron gun, during the movement of the plugs 2 under it.
- any other transport device 3 for providing this arrangement of plugs 2 could be used, by way of non-limiting example, a pneumatic conveying device.
- the plugs 2 are positioned step by step under the window 8 of electronic bombardment.
- FIG. 4 illustrates a cross-sectional view of a circular vessel cap 2, as well as various electron trajectories from the electron beam pulsed at the exit of the electron bombardment window 8, the trajectories of these electrons allowing the decontamination of specific areas of the plug 2.
- a plug of complex shape such as that illustrated in this figure, typically comprises:
- ribs 19 protruding from an inner face of the body 18, generally protruding parts to be screwed on and / or latched, intended to come into contact with the outside of the neck of the container, - a skirt 27 forming part of a tamper evident band, disposed on the inner face of the body 18,
- ribs 20 projecting from an inner face of the roof 17, typically an annular projection supporting a sealing lip.
- the plug 2 is a monomaterial block that can be made of polyethylene terephthalate (PET), high-density polyethylene (HDPE) or polypropylene (PP) or any other thermoplastic polymer.
- PET polyethylene terephthalate
- HDPE high-density polyethylene
- PP polypropylene
- This type of plug 2 comprises shaded areas 21, that is to say surfaces that can not be reached directly by an incident particle beam, for example the areas below the projecting portions of the body 18, skirt 27 and roof 17 of the cap 2 according to the direction of movement of the particles.
- the electron beam pulsed at the output of the electron gun is scattered towards the plugs 2 which scroll (or are positioned step by step) in front of the window 8 of electron bombardment.
- the diffusion of the electrons is conditioned by the propagation medium.
- the electrons from the electron gun constitute a rectilinearly distributed beam, and reach directly through the opening the surfaces of the plug 2 complex shape, sterilizing in the first place the internal apparent surfaces reached for example the roof 17 of the cap or the internal surfaces of its body 18.
- the propagation of the electrons is considered in a gaseous external medium (in particular air) which is preferably sterile.
- a gaseous external medium in particular air
- a portion of the electrons from the electron gun is diffused directly towards the apparent surfaces of the plug 2, while another portion of electrons of this beam undergoes backscattering phenomena in the air.
- These backscattering phenomena refer to collisions between the electrons and the particles of the external gaseous diffusion medium 11, for example elastic interactions generating deflections, that is to say modifications of the electron scattering angles without losses. (or minimal) energies.
- the primary electron beam is sufficiently homogeneous to impact all of the apparent surfaces of the plug 2.
- the primary electrons penetrate the material of the plug 2, and diffuse until they are absorbed. There is then an increase in the dose of electrons in the material, up to a maximum penetration thickness, a function of the material density of the plug 2 and the electron energy.
- dose is meant here the amount of energy from the electrons absorbed by the material. This energy absorption results notably from a transfer of energy from the electrons to the atoms of matter via inelastic collisions.
- the distribution of the electron dose is not progressive in the thickness of the material: this distribution depends on the penetration of electrons into the material.
- the penetration of electrons into the material is all the more important if the energy of the electrons is high and / or the density of the material of the irradiated object is low; a portion of the primary electrons is directly reflected on the surface of the plug 2, resulting from elastic or inelastic collisions with particles constituting the material of the plug 2.
- This physical phenomenon is commonly referred to as electron backscattering, also known as the English name "back-scattering".
- the left medallion of FIG. 4 illustrates by enlargement the different possible paths 23, 24, 25, 28 of an electron backscattered on the surface of the plug 2.
- the backscattered electron can itself be diffused direct (straight trajectory without deviation), such as the trajectory 24, or again undergo one or more elastic collisions in the external environment 11 of gas propagation as for the trajectories 23,25, 28.
- the trajectory 28 in particular allows to reach and therefore decontaminate a shaded area located under the skirt 27;
- the medallion on the right represents an enlargement of the trajectory 26 of a primary electron incident on the plug 2.
- This electron initially has a non-deflected trajectory between the electronic emission window 8 and an apparent surface plug 2, penetrates, then diffuses into the material of the plug 2, then successively undergoes two reflections finally leading to its backscattering in the gaseous medium.
- the electron beam pulsed at the output of the electron gun also makes it possible to decontaminate collars of containers that scroll (for example via a conveyor) or are positioned step by step in front of the window 8 electron bombardment.
- These necks may for example be part of a preform, a bottle, a tube or glued on a packaging brick.
- the neck is a mono-material block that can be made of polyethylene terephthalate (PET), high-density polyethylene (HDPE) or polypropylene (PP) or any other thermoplastic polymer.
- Figure 5 illustrates an exemplary embodiment of decontaminating a container neck.
- a sectional view of a circular container comprising a shoulder 29 and a neck 30 disposed upstream.
- the opening of the neck 30 is turned towards the window 8 of electronic bombardment.
- different electron trajectories from the electron beam pulsed at the outlet of the electron bombardment window 8 allow the decontamination of specific areas of the container neck 30.
- the illustrated container neck is of complex shape and comprises the following elements:
- the flange 31, the transfer ring 32 and the threads 33 all form ribs (helical in the case of threads 33) protruding, although of various radial extensions.
- This type of collar 30 also comprises zones 21 of shadow, that is to say surfaces that can not be reached directly by a beam of incident particles, as examples the areas below the collar 31, of the transfer ring 32, and nets 33.
- the rim 34 and the inner surface 35 are similar to visible areas of the neck 30, that is to say to areas that can be directly reached by a primary electron beam from the window 8 electron bombardment. As in the case of decontamination of plugs, the following physical phenomena are observed:
- the trajectories 36, 37, 38, 39 illustrate examples of electron trajectories backscattered in the air and undergoing elastic collisions on the neck 30 or the container.
- the trajectory 39 makes it possible to reach the shadow zone 21 below the flange 31 via an elastic collision on the shoulder 29 of the vessel followed by backscattering, resulting from a collision of the electrons with particles of the propagation medium; a part of the electrons penetrate the matter, diffuse into it, then undergo one or more elastic collisions before emerging. This situation is not illustrated here, but remains similar to that described for the right medallion of Figure 4.
- the primary electrons make it possible to decontaminate the visible parts of the neck 30, whereas the shadows 21 are decontaminated using the backscattered electrons.
- the backscattered electrons make it possible to reach through their trajectories the shaded areas of the plug 2 and / or the neck 30, and have a sufficiently high energy to be absorbed by the material of these zones, thus allowing their decontaminations.
- the use of a pulsed electron flow makes it possible both to obtain a flow of electrons of high intensity, ensuring the deposition of a sufficient lethal dose in the shadows, without degrading exposed surfaces exposed to the primary electron beam: the exposure time of the plug 2 and / or the neck 30 to the electronic bombardment is indeed reduced to the minimum possible.
- the more a material has heavy atoms the more the number of electrons backscattered by this material increases. Decontamination of caps and / or collars of complex-shaped containers by electron backscattering is therefore particularly advantageous for plugs and / or collars of containers made of PET, HDPE or PP materials.
- a potential difference of 250 kV is applied across a filament diode of this gun to obtain an anode current of 50 mA.
- the configurable parameters of this gun are the following: the number of pulses, the pulse duration of a pulse, the discharge voltage applied to the terminals of the diode, the current of the anode of the diode, the frequency of the emissions of the pulses.
- 10 taps of 10 ns, generated at a frequency of 100 Hz are used by applying a potential difference of 250 kV across the diode with an anode current of 5kA.
- the recharge time of the electron gun before you can generate a new source is here about 10 ms.
- T-treatment Total treatment time
- Nmax 3600 / T-treatment
- N Number of Pits 5 to 200 10 to 100 10
- a plurality of pulsed electron guns can be used simultaneously.
- the parallel use of several guns being known to those skilled in the art, this embodiment allows in particular to further reduce the duration of application of a tap on the object to be treated.
- the previously described embodiments make it possible to provide a decontamination process for cork and / or container necks that is effective (reduction in treatment times), and that is compatible with high rates, robust, and guarantees the non-degradation of stoppers and / or collars of containers (discoloration, crosslinking, odor migrations).
