Definitions
- the present invention relates to the field of bottling, and relates in particular to a device and a method for pressure-conditioning a container to be treated. at least partially filled with a content and sealingly sealed by a plug disposed above a headspace of the container, and on an associated pressure conditioning machine.
- content is understood to mean a liquid or semi-liquid food product intended to be marketed outside the cold chain such as an acidic fruit juice, in a container, a container within the meaning of the present invention being an envelope polymeric material such as a bottle, provided with a plug of known type, for hermetically closing the bottle after filling, usually screw.
- liquid or semi-liquid food contents are sensitive to microbial growth and the organoleptic qualities are very rapidly modified in the absence of sterilization treatment of the pathogenic organisms and / or the presence of oxygen.
- the high temperature heat treatment of the order of 90 ° C for a few seconds is also applied to liquids or semi-liquid foods with a pH lower than 4.7, such as juices. example.
- the liquid is treated in a specific unit, prior to the filling which must be performed in a sterile manner. It must therefore be ensured that the chain remains sterile.
- This known filling method consists in cold filling in a sterile environment, the container and its cap being cold sterilized by means of a sterilizing liquid and then rinsing and the contents then being introduced into this container in an aseptic atmosphere.
- the advantage is to use packaging that requires little material because the necessary mechanical properties are limited. The process does not cause volume variations due to temperature variations.
- a last solution among the main solutions known from the prior art is to heat-fill a package, that is to say to introduce the contents brought to a high temperature directly into the container without it having undergone a sterilization treatment.
- it is the content itself that ensures the sterilization of the container because it is introduced at a temperature allowing the destruction of pathogenic organisms, so greater than 73 ° C, generally 85 ° C.
- the package is closed and immediately agitated, generally by turning, to heat treat all internal surfaces of the container, including the inner face of the cap.
- the plug in the case of hot plugging is a known type of plug, monomatiere, obtained by molding, controlled before installation to avoid any installation of a faulty plug.
- Such caps are extremely inexpensive.
- the disadvantage of hot filling is to require a package that withstands both the temperature and secondly the collapse phenomenon related to the retraction of the volume of the liquid during cooling, this which depresses the interior of said container.
- the oxygen of the air trapped during filling is also "consumed" after cooling by the liquid or semi-liquid food composition, which causes a delayed depression which may also cause additional deformation of the container.
- the packaging must therefore be mechanically resistant and / or deformable, requires a large amount of material and often a specific architecture with panels to resist the deformations of this package and / or to compensate for the depression by appropriate deformations.
- funds can take two positions, one deformation inwardly under the effect of the depression so as to compensate said depression.
- the deformation of the bottom being under the bottle, this does not cause stability problem of the bottle when it is placed on said bottom, only the digging of the bottom is more pronounced, which is invisible, except to look from below. It is understood that such a background must be sophisticated, complex to achieve and induces a clear overhead.
- the purpose which is also that of the present invention is to be able to proceed in particular hot filling using bottles having an overweight of material as low as possible compared to the containers used for filling in sterile environment, cold.
- Patents which have proposed a method of compensation, such as patent applications FR 2322062 A1 and US 2015/0121807 A1 which propose injecting a gaseous fluid into the headspace through a specific closure member.
- a device consists in introducing a needle through the closure member, injecting a gas through the needle into the head space and removing said needle, the closure member ensuring itself a seal.
- a membrane which can only be a barrier to the liquid during hot filling for example because the liquid will not pass behind the membrane, then the closure member is perforated which introduces possible organisms understood behind the membrane that will migrate into the container.
- Another device also uses an even more specific cap, that described in the patent application WO 2009142510 A1.
- This plug is manufactured with an opening. After filling, the head space is placed in a pressure vessel, a plug is inserted into the hole provided for this purpose, said plug being immobilized in the hole by means mechanical.
- Such a process is totally unimaginable industrially, both from the point of view of rates and price and control difficulties and even implementation.
- the devices known in the prior art do not allow to accurately check the sealing quality of the hole formed in the plug to ensure a perfect seal of the container.
- the present invention aims to solve the disadvantages of the prior art, by proposing a device and a method for pressure packaging a container to be treated at least partially filled with a content and sealed with a stopper arranged above a head space of the container, said device comprising a hood with a needle and a heating cannula disposed therein so that their respective axes of movement are intersecting at a point in the material of the cap or above the material of the cap when the cap is approached on the cap, the end of the heating cannula being convex, preferably hemispherical, which allows to proceed in particular to a hot filling using bottles having a overweight material as low as possible compared to the containers used for filling in cold sterile environment, and allowing and also to compensate for depression in cold-filled containers that may experience deformation by depression, especially if the containers themselves have low mechanical strength.
- the convex shape of the end of the heating cannula makes it possible to carry out a precise verification of the quality of the shutter by the heating can
- the subject of the present invention is therefore a device for pressure-conditioning a container to be treated at least partially filled with a content and sealed with a stopper placed above a head space of the container, said device comprising a cover which includes inside thereof a piercing needle, fluid injection means and a fused shutter heating cannula, said cap configured to be sealingly abutted against the outer surface of the cap; said needle being adapted to move linearly to drill a hole through the plug, said fluid injection means being configured to introduce a fluid into the head space through said hole, said heating cannula being adapted to linearly moving to close said hole by melting the material of the plug, characterized in that the needle and the heating cannula are arranged in the hood so that their respective axes of movement are intersecting at a point in the material of the cap or above the material of the cap when the hood is approached on the cap, and in that the end of the heating cannula is convex.
- the end of the heating cannula is preferably hemispherical.
- said device for pressure-conditioning a container to be treated makes it possible in particular to perform a hot filling using bottles having an overweight of material as low as possible compared to containers used for filling in cold sterile environment, and allows also to compensate for the depression in cold-filled containers that may suffer deformation by depression, especially if the containers themselves have a low mechanical strength.
- the needle and the heating cannula are inclined with respect to each other so that their respective longitudinal axes of displacement intersect at the same point in the material of the plug or above the material of the plug.
- said point is at the center of the upper surface of the plug.
- the skilled person can easily proceed by trial and measurement to ensure that in the closed position of the heating cannula on the cap, the top of the convex shape of the cannula coincides with the hole formed by the needle: the axes of displacement are thus intersecting on the material of the cap or above it, depending on the convex shape adopted by the end of the heating cannula.
- the needle is movable, in the position of docking the cap on the cap, between a retracted position and a piercing position to pierce the cap.
- the heating cannula is movable, in the position of docking the cover on the cap, between a rest position and a closed position to seal the hole formed in the stopper by the needle, the plastic material of the plug in contact with the heating cannula.
- the needle is never in contact with the contents during drilling.
- the plug used in the context of the invention and therefore in this process is a conventional one-piece cap, without internal membrane and therefore inexpensive and easy to recycle.
- the invention is however not limited to this respect.
- the following plugs are also within the scope of the present invention, and may be used with the method of the invention:
- a plug comprising an annular membrane (or liner or liner) hollowed out in its central part,
- a plug comprising a solid membrane (or inner liner or solid liner) but with a central thickness less than the minimum thickness necessary for self-sealing in the case of a drilling and a subsequent withdrawal of a needle from the plug, this minimum thickness required being below 0.2 mm,
- a plug comprising a solid membrane (or inner liner or solid liner) of thickness between 0.2 mm and 0.8 mm, with a polyethylene / ethylene-vinyl acetate (PE / EVA) type material which does not possess no known self-sealing characteristic after removal of a piercing needle with a diameter of between 0.1 mm and 3 mm.
- PE / EVA polyethylene / ethylene-vinyl acetate
- This device is preferably used for hot content filling, but can also be used for cold content filling.
- the heating cannula reseals, by fusion of the plastic material of the cap, the hole formed in the cap by the needle, which ensures the final seal of the container while compensating for the depression in the container.
- the container thus contains a content with a pressure balanced for the least and preferably under a slight pressure so that the pressure difference internal with the external pressure of the container avoids generating any collapse of the container.
- the convex, preferably hemispherical, shape of the end of the heating cannula makes it possible to carry out a precise verification of the quality of closure by the heating cannula of a hole formed in the stopper by the needle.
- the shape of the obturation formed by the convex heating cannula depends on the shape of the end of the heating cannula, the temperature of the end of the heating cannula, the contact time of the heating cannula with the cap and the depth of penetration of the heating cannula into the cap.
- the temperature of the end of the heating cannula determined according to the material constituting the cap, the contact time determined as a function of the desired treatment time, the Those skilled in the art will be able to adapt the depth of penetration into the cap by tests and measurements. A characteristic mark of a certain diameter will be formed on the upper surface of the plug, which, because of the shape, the temperature of the tip of the cannula and the contact time, will ensure that the heating cannula has had sufficient penetration to ensure a tight seal.
- the device further comprises an optical means configured to check the quality of closing the hole in the plug by the heating cannula.
- the optical means may be a camera or an optical fiber connected to an optical sensor.
- the optical means may be arranged in the hood or at a station downstream on a production line having the device of the invention.
- the device further comprises an optical or inductive means arranged in the cover and configured to check the integrity of the needle after drilling the hole.
- a remote optical camera can control the filling level of the container at the end of the pressure conditioning process to detect a possible breakage of the needle. Indeed, during normal processing, the content level must drop to a predetermined level, while in case of non-drilling and therefore no introduction of fluid, the level of content will not drop.
- a proximity sensor system could also control the presence of the complete and unbroken needle. Such proximity sensor systems could for example be a photoelectric or magnetic cell.
- the needle has a pointed end in the form of a cone.
- said needle is more solid compared to a hypodermic needle with beveled end used in the prior art, which prevents the needle from breaking during the piercing step.
- Said needle ensures a hole by penetration into the plastic material of the plug, by deformation and repoussage of the material, without tearing material. No plastic waste plug thus falls into the contents of the container.
- the diameter of the drilling hole must allow to combine rapid inflation (largest diameter possible) and welding safety (smallest possible diameter).
- a 0.7 mm diameter needle seems to be a good compromise.
- the diameter of the needle may be between 0.3 and 0.8 times the thickness of the plug.
- the thickness of the plug is defined as the maximum thickness of the flat surface of the plug from which extends the skirt of the cap bearing the thread.
- the needle is full, the fluid injection means comprising at least one fluid inlet adapted to receive a fluid under pressure and to inject it into the inside of the hood is sealed against the cap.
- the solid needle is withdrawn from the hole formed in the plug to allow the introduction of the fluid into the head space of the container through said hole.
- a sterilization of the outer surface of the plug before berthing the cap on the cap is mandatory so as not to pollute the contents during the introduction of the fluid into the headspace.
- the removal of the needle during the injection of fluid also avoids any splashing of the content on the needle during the introduction of fluid that creates turbulence of the surface of the contents, for improved hygiene.
- the pointed end of the needle is solid, and the remainder of the needle comprises a longitudinal central bore and at least two opposite lateral holes connecting said central bore with the outside of the needle.
- the needle near the sharp end of the needle, the fluid injection means comprising at least one fluid inlet adapted to receive a fluid under pressure and to inject it into the central bore of the needle at the end of the needle opposite the pointed end of the needle.
- the needle is full at its tip but pierced at its center with two lateral openings, which makes it possible to introduce a fluid into the headspace of the container while the needle is still in its piercing position, the fluid being diffused laterally in the head space by the two lateral holes of the needle, thus making it possible to avoid the setting in eventual turbulence of the contents and splashing during the introduction of fluid.
- This second embodiment avoids the prior sterilization of the outer surface of the plug, which is an important point from an industrial point of view.
- the needle is heated by a heating means.
- the heating of the needle makes it possible both to sterilize the needle and to facilitate the drilling of the plastic material of the stopper.
- the needle is preferably heated to a temperature above 95 ° C for sterilization and below 130 ° C to prevent possible melting of the plastic material of the plug during drilling and gluing of plastic particles on the needle that could then come off when drilling the cap of another container in a next cycle.
- the temperature of the needle is preferably maintained and continuously monitored by a resistor / probe placed in the needle holder.
- the subject of the present invention is also a process for the pressure-packing of a container to be treated at least partially filled with a content and sealed with a stopper placed above a head space of the container, at the same time.
- a pressure conditioning device as described above, characterized in that it comprises the following steps: sealing the cover of said device on the outer surface of the plug; drilling a hole through the stopper with the needle of said device; introducing a fluid into the head space of the container via said hole, formed through the cap, using the fluid injection means of said device, so as to obtain a residual pressure at least equal to the atmospheric pressure in the headspace of the container; closing said hole by melting the plug material with the aid of the heating cannula; and removing the hood.
- said pressure-conditioning method of a container to be treated makes it possible in particular to perform a hot filling using bottles having an overweight of material as low as possible compared to the containers used for filling in cold sterile environment, and also makes it possible to compensate for the depression in cold-filled containers which can undergo deformation by depression, especially if the containers themselves have a low mechanical strength.
- the temperature of the heating cannula and the contact time can be set individually to obtain the desired penetration / weld and are continuously monitored by the pressure conditioning device.
- the temperature at the end of the heating cannula is of the order of 140 ° C - 220 ° C to ensure rapid melting of the plastic material of the cap.
- a minimum force for example using a cylinder controlled at 7 bar, is applied to the heating cannula to ensure a significant compression of the plastic during the melting phase to fill the hole.
- An insufficient pressure of the heating cannula despite the good temperature and the good contact time compromises the quality / sealing of the weld.
- the Applicant has found good weld impressions for a contact time of 0.4-0.5 seconds at 7 bars, with a temperature of 180 ° C at the end of the cannula, for plugs in high density polyethylene (HDPE).
- HDPE high density polyethylene
- the heating of the cannula is provided by a resistance / temperature probe connected to the device.
- a water cooling circuit placed in the hood preferably ensures the hood is held at a "reasonable" temperature.
- the needle is withdrawn from the hole before the fluid introduction step.
- the needle can be raised, before the fluid injection step, while maintaining the pressure between the cap and the cap, the piercing is therefore "clean "without chips or waste by pushing the plastic material of the cap only, the removal of the needle during the injection of fluid also to avoid splashing of the contents on the needle when introducing the fluid that creates turbulence of the surface of the contents, for improved hygiene.
- the needle is held in the hole during the fluid introduction step, the fluid introduction being through the central bore and the at least two side holes of the needle.
- the fluid is diffused laterally in the head space by the two lateral holes of the needle, thereby avoiding the possible turbulence of the contents and splashing during the introduction of fluid, and also to prevent prior sterilization of the outer surface of the cap.
- the method further comprises, after the shutter step, a step of checking the quality of closing the hole in the stopper with the aid of the optical means.
- Leak test systems are currently available to test the quality of the weld. However, for a hole of about one micron (which allows the return of atmospheric pressure of the container in a week), the control time is about thirty seconds, so it would take a number of control covers fifteen times greater than number of treatment covers, which is prohibitive.
- the optical means therefore allows the verification of the shutter quality immediately after the shutter step when the cover is still docked on the stopper, or on a downstream station on a production line in which the device is placed according to 1 invention.
- the verification step comprises the following substeps: capturing, by the optical means, an image of the plug at the level of the circular closure formed by the convex heating cannula; measuring the diameter of the captured circular filling; and comparing the measured diameter to a threshold value to determine whether or not the shutter quality is acceptable.
- the optical means allows a visual control of the melt shutter to measure the penetration of the cannula and guarantee the quality of the weld.
- the step of introducing fluid into the headspace comprises introducing a fluid into an initial phase at a first pressure value, and then introducing a fluid into a final phase at a first stage. second pressure value lower than the first pressure value for an acceleration of the process according to the invention.
- the fluid in the case of a hot filling at a temperature above 73 ° C., the fluid is introduced into the headspace after cooling the contents to a temperature below 45 ° C. .
- the fluid introduction pressure is configured to generate a residual pressure in the container, between 1.01 bars and 2.5 bars, and preferably between 1.01 bars and 1, 4 bars.
- the fluid is an inert and sterile gas such as nitrogen, especially in gaseous form.
- the method further comprises, before, during and / or after the bonnet docking step, a step of circulating sterile fluid between the cap and the cap, preferably an inert gas, more preferably nitrogen.
- this circulation of sterile fluid prevents bacteria from entering the space between the cap and the cap from the outside, to ensure the sterility of the container.
- An overpressure is created between the cap and the cap to maintain a positive pressure greater than or equal to the internal pressure of the container to the melt shutter.
- the method further comprises, before the cap berthing step on the cap, a step of sterilizing the outer surface of the cap by one or more of a punctual heating, a chemical sterilization , a vapor, a pulsed light emission or the like.
- punctual heating or chemical sterilization using a sterilizing liquid ensures the destruction of pathogenic organisms present on the outer surface of the plug.
- the present invention further relates to a pressure conditioning machine comprising at least one pressure conditioning device as described above, said pressure conditioning machine further comprising a means for holding in the container position with respect to which the cover of the at least one pressure conditioning device is movable between a rest position remote from the holding means in the container position and a docking position in which the cover is sealed against the cap of the container to be treated.

- the container 2 is filled with the hot content, it is plugged by the plug 3 of known type, namely a monolithic and monomatized injection-molded or compression-molded screw plug without any additional sealing element.
- the seal is obtained by contact under mechanical pressure of the material of the plug 3, in this case its inner face on the material of the peripheral edge of the neck 2a of the container 2, the screwing to exert said mechanical pressure required.
- said cap 3 When closing, said cap 3 leaves a head space. This space results from filling without overflow because the content should in no way overflow and end up on the lip of the neck 2a before closing because the content would then be an entry door under the cap 3 and the container 2 would be unfit for sale .
- the plug 3 is free from any mechanism or other pressure compensation accessory.
- the air trapped in the head space is hot but at atmospheric pressure.
- the present invention also applies to certain plugs commonly used, particularly in the United States, which are bi-material type with an inner membrane used to ensure only the seal between the surface of the neck of the container 2 and the cap 3 by compression during screwing, unlike the inner lip for the monomatiere-type plugs.
- this inner membrane for such a bi-material cap does not have the necessary characteristics to ensure a self-sealing of the plug in the case of a piercing with a needle and then a withdrawal of the needle out of the cap.
- the container 2 is able to receive a content at the sterilization temperature retained without degradation but is free of depression compensation means.
- the container 2 is set in motion immediately after filling with the contents, in order to put all the internal surfaces of the container 2 in contact with the contents brought to the sterilizing temperature.

- the container 2 is partially filled with a content 12 so that a head space 13 without content remains at the neck 2a of the container 2, the container 2 being sealed by the cap 3 disposed above the head space 13 of the container 2.
- the piercing means 5 comprise a piston 14 at the end of which is fixed a needle 15, said piston 14 being able to move linearly in a cylinder 16 formed on the cover 4, the stroke of the piston 14 being limited by a chamber of piston 17 formed in the upper end of the cylinder 16.
- the needle 15 is configured to pierce the cap 3 when the cap 4 is docked on the cap 3 and the piston 14 is in its extended position.
- the melt sealing means 7 comprise a piston 18 at the end of which is fixed a heating cannula 19, said piston 18 being able to move linearly in a cylinder 20 formed on the cover 4, the piston 18 being limited stroke by a piston chamber 21 formed in the upper end of the cylinder 20.

- the pistons 14 and 18 can be actuated electrically or hydraulically. In order not to overload the figures, the power supply or hydraulic actuation son of the pistons 14 and 18 have not been shown in the figures. Similarly, the heating elements for heating the needle 15 or the heating cannula 19, as well as their power supplies respective electric wires, have not been shown to avoid overloading the figures.
- the fluid injection means 6 comprise a plurality of fluid inlets adapted to receive a pressurized fluid and to inject it into the internal cavity 22 of the cover 4, the cover 4 being able to contain up to five inputs of fluid 6.
