    [0001] The present invention is a process for the overpressure treatment of a container with its contents, after filling and capping, in particular of a treatment method of a container. liquid or semi-liquid acidic food such as a fruit juice in a bottle of polymeric material.
    [0002] Subsequently, it is meant by content a liquid or semi-liquid food product intended to be marketed outside the cold chain, in a container, a container within the meaning of the present invention being an envelope made of a polymer material such as a bottle. , provided with a cap for hermetically closing the bottle after filling.
    [0003] Cardboard, foil and polymeric foil packaging, glass, metal and pouch plastic film packaging are not affected by the present invention. The contents are sensitive to microbial growth and the organoleptic qualities are very quickly modified in the absence of sterilization treatment of pathogenic organisms. In known manner, the high temperature heat treatment of the order of 90 ° C for a few seconds, also called flash pasteurization, is also applied to liquid or semiliquid food having a pH below 4.7, such as juice for example. In this process, the liquid is treated in a specific unit, prior to filling which must be carried out sterile. It must therefore be ensured that the chain remains sterile. This filling process consists of cold filling in a sterile environment. The container and its cap are cold sterilized by means of a sterilization liquid and then a rinse and the liquid is then introduced into the 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 result in volume variations related to temperature variations. In addition, the necessary mechanical properties being limited, external aesthetic forms are more free. Nevertheless, this induces complex, expensive and rigorous maintenance facilities and itself expensive. Moreover, the quality control can only be by sampling, so there is no systematic control and therefore no certainty as to the sterilization of the liquid or semi-liquid food thus conditioned. Another known solution is that of sterilization simultaneously with filling by introducing a sterilizing liquid. It is understood that the addition of a sterilizing product, which is a chemical compound, is not necessarily accepted by all the sanitary laws of the countries and the consumer himself may be reluctant to absorb not only the liquid food product. or semi-liquid he has chosen but also the sterilizing product introduced. In addition, the addition of a sterilizing product must be mentioned on the labels and such products will not fall into categories without preservatives or bio. Such preservatives may induce changes in the organoleptic qualities both during storage and after opening the package. A final solution among the main solutions known from the prior art is to fill a package with heat. In this case, it is the liquid that ensures the sterilization because it is introduced at a temperature allowing the destruction of pathogenic organisms therefore greater than 73 ° C, generally 75 ° C.
    [0004] The package is closed and then immediately agitated, generally by inversion to treat all surfaces including that of the stopper. The solution is interesting because it ensures that each package is necessarily sterilized internally, without there being any lack. The disadvantage is to require a package that withstands both the temperature and the collapse phenomenon related to the retraction of the volume of the liquid during cooling, which depresses the interior of said container. The packaging must be mechanically strong, deformable and requires a large amount of material, a specific architecture with panels to resist the deformations of this packaging and / or to compensate the depression by appropriate deformations. It should be noted that this goes in the opposite direction to the need for sustainable development, which aims to reduce the quantities of polymer material used, which also has a clear impact on the price of manufacturing and an impact on recycling, thus having an impact on the final price.
    [0005] However, this method is the one that requires the simplest packaging lines both in installation and maintenance, which is simple to control since the main control focuses on a single parameter: the temperature of the liquid. Other compensation solutions have been implemented, one of them for example consists of introducing a drop of liquid nitrogen into the head space immediately before plugging. The liquid nitrogen goes into a gaseous state with a very large increase in volume, which places the volume of the bottle under pressure and makes it possible to compensate as the cooling of the volume of retraction of the liquid. In the final state, at room temperature the equilibrium is found and the nitrogen can only cause additional inerting. Advances in processes and container materials have improved performance. The market of several billion bottles is therefore very incentive. Nevertheless, the object of the present invention is also to be able to heat-fill using bottles having an overweight of material as low as possible compared to the containers used for filling in sterile environment, cold. It is therefore necessary to provide a hot filling process which makes it possible to compensate for the decrease in volume of a few percent on cooling, a decrease which causes deformation of the bottle and renders it unfit for marketing. There is also a problem of depressurizing cold filled containers as the product absorbs oxygen from the air. There is then a decrease in the volume of air in the headspace and thus a depression. The present invention is directed to a method of hot filling, that is to say at a temperature above 75 ° C, a container with a content, with a compensation of the depression generated in said container.
    [0006] The method is now described with reference to the block diagram shown in the appended single figure. This description is established according to a particular embodiment, not limiting, for a container which is a bottle. There is also provided a variant embodiment.
    [0007] In addition, this method is implemented by means of a device shown schematically in the accompanying drawings, drawings in which the different figures show: FIG. 1A: a view of the sterilization step of the closure means, 3035876 FIG. 1B: a view of the combined piercing piercing / piercing piercing means, FIG. 1C: a view of the combined injection piercing piercing / piercing means, FIG. 1D: a view of the piercing piercing means melt shutter / shutter step. The filling method according to the present invention consists in filling a hot container, especially PET, polyethylene terephthalate, with a content, brought to a temperature capable of destroying pathogenic organisms ie a temperature greater than 73 ° C, in this case 75 ° C. Once the container is filled, it is plugged by closure means, in this case a plug which leaves a space 18 head. The closure means are free of any mechanism or other pressure compensation accessory.
    [0008] The container is adapted to receive a content at the sterilization temperature retained without degradation but is free of depression compensation means. The method provides for moving the container in order to contact all internal surfaces of the container in contact with the contents brought to the sterilizing temperature.
    [0009] The container and its liquid are then cooled in a water spray cooling tunnel. When the container reaches a temperature below 73 ° C the container, because of the material that constitutes it, collapses because the internal volume of the contents relative to the container is reduced to 3 to 5%. This reduction increases as the cooling progresses. The phenomenon of collapse is close to its maximum at a temperature below or equal to 45 ° C. The method provides an injection of inert gas through the closure means in the head space of the container, at any time of the cooling but more particularly when the temperature is less than or equal to 45 ° C.
    [0010] The next step consists in closing the passage generated by the injection operation through the closure means within a period of between 0 and 5 seconds.
    [0011] The injection pressure and the capping time are combined so that the residual pressure in the container is greater than atmospheric pressure, more particularly between 1.01 bar and 2.5 bar and more particularly between 1.01 bar. and 1.4 bars.
    [0012] According to an improvement of the invention, the closure means are sterilized externally before drilling, by spot heating or by chemical sterilization. Preferably, the injection is performed by means of a needle, in a sterile environment. The injected gas is preferably a neutral gas so as not to cause oxidation of the contents, subsequent to bottling, for example nitrogen, especially in liquid form. Clogging of the hole made is ensured by any means among which, we can mention the establishment of a lid. Another solution consists in melting the material of the closure means thus drilled concomitantly at the exit of the needle with a needle equipped with heating means, by melting material on the edges of said hole or by supplying molten material immediately. after removal of the needle. The container thus contains a content under pressure or under a slight pressure at least equal to atmospheric pressure so that the pressure delta with the ambient air avoids generating any collapse.
    [0013] In the appended figures, there is shown a device for implementing the method described above. In FIG. 1A, it is proposed to sterilize the closure means 10 comprising a stopper 12 by a sterilant liquid spraying 14. The sterilizing liquid ensures the destruction of the pathogenic organisms present on the outer surface of the stopper.
    [0014] In FIG. 1B, after the sterilization, combined means 16 are used comprising piercing means 18, injection means 20 and fusion sealing means 22, these elements being arranged in a cover 24 in the form of plug. Advantageously, the piercing means 18 and the closure means 22 are arranged diametrically with respect to the cap. During this step, the cover 24 is docked on the stopper tightly. This step of docking the cover 24 is completed by a neutral gas sweep such as nitrogen gas, under pressure under this hood. The piercing means 18 provide a hole by penetration into the plastic material, by deformation, without tearing off material. In FIG. 1C, it can be seen that the piercing means 18 comprise a constriction making it possible to drill a diameter greater than that of the constriction. Thus, by pressurizing the volume defined by the hood, it is possible to inject gas through the diameter differential between the throat and the drilled hole. The head volume is thus pressurized, the same pressure as that generated under the cover 24. In Figure 1D, the cover 24 is rotated to position the closure means 22 to the right of the cut hole. The closure means 22 consist of a hot cannula which melt the plastic material of the plug in order to plug the hole by melting the material of said plug. It is understood that the container thus pressurized or under slight pressure does not pose a problem and at most, it reinforces the rigidity of said container.
    [0015] Such a process allows hot filling in containers, for example PTFE, polytetrafluoroethylene with reduced weights of the order of 10 g of material for a volume of 1 liter. No particular architecture should be studied for the wall, any technical panel and / or petaloid bottom become useless.
    [0016] 20 The forms of containers are in fact much freer and more sober, recycling is less expensive since the amount of material used is less. Providing the container under atmospheric pressure or slight pressure allows stacking and palletizing. Such a bottling line is much simpler than a sterile bottling line and above all it ensures complete safety in the filling since it is carried out hot. The sterile station only concerns one operation. This line has the advantage of allowing the use of containers of material resistant to bottling temperature but not necessarily to collapse since this collapse has been eliminated combined with the safety of hot filling.
