Definitions
- the present invention relates to containers and to a process for pasteurizing or sterilizing products contained in these containers.
- the invention applies very particularly to containers used in the food industry, in particular to cans or "trays", but it also applies to any other container intended to contain objects which, after pasteurization or sterilization or other heat treatment, must be protected from any danger of soiling or contamination.
- FR-A-2 656 280 already discloses an automatic shutter device by thermal conditioning effect for food preparation for deferred consumption in which a tray has a tongue hinged on its edge and folded towards the inside of the tray after filling. by food, the tongue comprising a perforated seat in which is deposited a drop of fusible composite resin which becomes porous at a determined temperature.
- the seat has an orifice closed by the porous material which comes directly into contact with the food contained in the tray which can therefore be caused to be polluted by the porous substance.
- the container according to the invention makes it possible to carry out, directly in the container presented to consumers, pasteurization or sterilization, without decanting or handling.
- the method of manufacturing the container requires only relatively simple equipment and its implementation during filling does not require any special equipment.
- the integrity of the foodstuffs contained in the container, especially their color, is better preserved than so far.
- the process for the pasteurization of products in these containers is as defined in claim 1. It consists, for example, in ensuring that a substance with a melting point between 65 ° C and 150 ° C is located in a housing defined in the upper part of a container and communicating with the interior of the container through a first orifice and with the outside through a second orifice, to heat the container and its housing to a temperature at least equal to the melting point of the substance during 5 to 90 minutes, then cool the substance to a temperature below its melting point faster than the rest of the container and its contents, then cool the rest of the container and its contents to a temperature less than or equal to room temperature .
- the container and its housing When the container and its housing are heated to a temperature above the melting point of the substance, it melts and the contents of the container give off gases and steam, which create an overpressure of the interior of the container by report to the outside.
- This overpressure prevents the substance which has become liquid from entering the interior of the container through the first orifice and causes at least partial delivery of the substance into the second orifice.
- the substance does not, however, close the second orifice at this stage, so that the water vapor and the gases coming from inside the container can escape through this second orifice. This therefore makes it possible to carry out cooking, pasteurization or sterilization without having to fear an explosion of the container.
- the second orifice has a circular cross-section, so that the substance begins to line the interior wall by initiating its exit to the outside, while leaving a passage for gases and water vapor.
- good results are obtained when the second orifice has a diameter of between 0.7 and 2 mm.
- a fusible adhesive is used in particular in an amount of 10 to 100 mg depending on the heat treatment temperature corresponding to pasteurization or to sterilization or to cooking.
- meltable glue food hot-melt glues can be used in particular in the viscosities below.
- the substance has a viscosity of 6 Pas to about 200 Pas at the firing temperature. It is thus best suited to line the second orifice without being completely expelled from the housing.
- the temperature interval between the melting point and the softening point of the substance is less than 15 ° C and, preferably, greater than 7 ° C, so that as soon as the substance has cooled substantially compared to the rest of the container, it takes a quasi-solid pasty state and cannot fall through the first orifice and contaminate the contents of the container, since the pressure prevailing in it is still enough to repel the substance.
- the substance is preferably food grade when the container is intended for this industry.
- the container may in particular be a tin can, the housing preferably being attached to the lid and in particular formed on or under it, or a tray, the housing possibly being advantageously formed on a rim of the body of the covered tray. a sealing film.
- the element can be added or, if necessary, come from molding with the container.
- the can shown in Figure 1 has a body 3 sealed by a cover 2.
- the cover 2 defines with a domed plate 6 a housing 1 for receiving 25 mg of a fusible resin 4 having a melting point 110 ° C.
- the housing 1 communicates with the inside of the box through a first orifice 7 having a section of 3 mm 2 and with the outside through a second orifice 8.
- the latter has a circular cross section with a diameter of 1 mm.
- the viscosity of substance 4 is 10 Pas at 110 ° C.
- the housing 1 is constituted by a part of the cover 2 stamped so as to form a bulge and by a flat plate 5.
- the housing 1 is formed by a deformation of the cover by stamping and by a metal plate 5.
- Figures 5 to 7 show a tray. It comprises a fuse valve formed by a housing 11 perforated in the lower part and formed in the horizontal rim 13 of the tray 12, advantageously in a corner or on the side.
- This seat receives from manufacture a drop of fusible resin 14, advantageously in a corner or on the side, which solidifies. When it melts, it allows undesirable gases to pass, as well as the expanded hot air and the water vapor which escapes during cooking due to the overpressure which is created inside the tray during cooking.
- Small channels 18 are arranged in the thickness of the material making up the tray 12 so as to put in communication, after sealing the film 17, the interior volume of the tray with the housing 11 of the fuse valve.
- the fusible resin freezes again causing the closing of the fusible valve ( Figure 3), thus preventing outside air from entering the tray.
- the vacuum created in the tray 12 by temperature difference adds to the preservation qualities of food products, which are immune to the risks of oxidation. For example, the colors of green vegetables are perfectly preserved.
Abstract
Description
La présente invention se rapporte aux récipients et à un procédé de pasteurisation ou stérilisation de produits contenus dans ces récipients. L'invention s'applique tout particulièrement aux récipients utilisés dans l'industrie alimentaire, notamment aux boîtes de conserve ou aux "barquettes", mais elle s'applique également à tout autre récipient destiné à contenir des objets qui, après pasteurisation ou stérilisation ou autre traitement thermique, doivent être préservés de tout danger de souillure ou de contamination.The present invention relates to containers and to a process for pasteurizing or sterilizing products contained in these containers. The invention applies very particularly to containers used in the food industry, in particular to cans or "trays", but it also applies to any other container intended to contain objects which, after pasteurization or sterilization or other heat treatment, must be protected from any danger of soiling or contamination.
On connaît déjà au FR-A-2 656 280 un dispositif d'obturateur automatique par effet thermique de conditionnement pour préparation alimentaire à consommation différée dans lequel une barquette comporte une languette articulée sur son bord et repliée vers l'intérieur de la barquette après remplissage par les aliments, la languette comportant un siège perforée dans lequel est déposée une goutte de résine composite fusible qui devient poreuse à une température déterminée. Le siège comporte un orifice fermé par la matière poreuse qui vient directement en contact avec les aliments contenus dans la barquette qui peuvent donc être amenés à être pollués par la substance poreuse.FR-A-2 656 280 already discloses an automatic shutter device by thermal conditioning effect for food preparation for deferred consumption in which a tray has a tongue hinged on its edge and folded towards the inside of the tray after filling. by food, the tongue comprising a perforated seat in which is deposited a drop of fusible composite resin which becomes porous at a determined temperature. The seat has an orifice closed by the porous material which comes directly into contact with the food contained in the tray which can therefore be caused to be polluted by the porous substance.
Le récipient suivant l'invention permet d'effectuer, directement dans le récipient présenté aux consommateurs, une pasteurisation ou une stérilisation, sans transvasement ni manipulation. Le procédé de fabrication du récipient ne nécessite qu'un équipement relativement simple et sa mise en oeuvre lors du remplissage ne nécessite pas d'appareillage spécial. L'intégrité des denrées contenues dans le récipient, notamment leur couleur, est mieux préservée que jusqu'ici.The container according to the invention makes it possible to carry out, directly in the container presented to consumers, pasteurization or sterilization, without decanting or handling. The method of manufacturing the container requires only relatively simple equipment and its implementation during filling does not require any special equipment. The integrity of the foodstuffs contained in the container, especially their color, is better preserved than so far.
Les récipients sont définis aux revendications 6 et 7.The containers are defined in
Le procédé de pasteurisation de produits dans ces récipients est tel que défini à la revendication 1. Il consiste par exemple à faire en sorte qu'une substance à point de fusion compris entre 65°C et 150°C se trouve dans un logement délimité dans la partie supérieure d'un récipient et communiquant avec l'intérieur du récipient par un premier orifice et avec l'extérieur par un second orifice, à chauffer le récipient et son logement à une température au moins égale au point de fusion de la substance pendant 5 à 90 minutes, puis à refroidir la substance à une température inférieure à son point de fusion plus rapidement que le reste du récipient et son contenu, puis à refroidir le reste du récipient et son contenu à une température inférieure ou égale à la température ambiante.The process for the pasteurization of products in these containers is as defined in claim 1. It consists, for example, in ensuring that a substance with a melting point between 65 ° C and 150 ° C is located in a housing defined in the upper part of a container and communicating with the interior of the container through a first orifice and with the outside through a second orifice, to heat the container and its housing to a temperature at least equal to the melting point of the substance during 5 to 90 minutes, then cool the substance to a temperature below its melting point faster than the rest of the container and its contents, then cool the rest of the container and its contents to a temperature less than or equal to room temperature .
Lorsque l'on chauffe le récipient et son logement à une température supérieure au point de fusion de la substance, celle-ci fond et le contenu du récipient dégage des gaz et de la vapeur, qui créent une surpression de l'intérieur du récipient par rapport à l'extérieur. Cette surpression empêche la substance devenue liquide de pénétrer à l'intérieur du récipient par le premier orifice et provoque le refoulement au moins partiel de la substance dans le second orifice. La substance n'obture pas néanmoins, à ce stade, le second orifice, en sorte que la vapeur d'eau et les gaz issus de l'intérieur du récipient peuvent s'échapper par ce second orifice. Cela permet donc d'effectuer une cuisson, une pasteurisation ou une stérilisation sans avoir à redouter une explosion du récipient. Ce chauffage achevé, le refroidissement localisé rapide et précoce de la substance, à une température inférieure à son point de fusion, alors que le reste du récipient et son contenu restent sensiblement à la température à laquelle ils viennent d'être portés, provoque la solidification rapide de la substance dans le logement et dans le second orifice, une partie d'ailleurs de la substance formant même un bourrelet de section transversale supérieure à celle du second orifice à la sortie de celui-ci, de sorte que la substance est comme rivetée au récipient et en assure la parfaite étanchéité. Lors du refroidissement du récipient et de son contenu à une température inférieure ou égale à la température ambiante, par exemple à -4°C ou même, à une température de surgélation, la substance solide reste en place dans le second orifice en continuant à assurer l'étanchéité. Le récipient suivant l'invention et son procédé de fabrication permettent donc d'obturer la boîte d'une manière étanche juste après que les gaz et la vapeur d'eau, qui doivent s'en échapper, l'ont fait, et cela, automatiquement, sans nécessiter quelle que manipulation que ce soit.When the container and its housing are heated to a temperature above the melting point of the substance, it melts and the contents of the container give off gases and steam, which create an overpressure of the interior of the container by report to the outside. This overpressure prevents the substance which has become liquid from entering the interior of the container through the first orifice and causes at least partial delivery of the substance into the second orifice. The substance does not, however, close the second orifice at this stage, so that the water vapor and the gases coming from inside the container can escape through this second orifice. This therefore makes it possible to carry out cooking, pasteurization or sterilization without having to fear an explosion of the container. This heating completed, the rapid and early localized cooling of the substance, to a temperature below its melting point, while the remainder of the container and its contents remain substantially at the temperature to which they have just been brought, causes the solidification of the substance rapidly in the housing and in the second orifice, part moreover of the substance even forming a bead of cross section greater than that of the second orifice at the outlet thereof, so that the substance is as riveted to the container and ensures its perfect seal. When the container and its contents are cooled to a temperature less than or equal to ambient temperature, for example at -4 ° C. or even, at a freezing temperature, the solid substance remains in place in the second orifice while continuing to ensure sealing. The container according to the invention and its manufacturing process therefore make it possible to close the box in a sealed manner just after the gases and water vapor, which must escape therefrom, have done so, and this, automatically, without requiring any manipulation whatsoever.
Pour assurer que, lors du traitement thermique, tel que de la pasteurisation ou de la stérilisation, les gaz puissent s'échapper par le second orifice, alors cependant que celui-ci commence à être empli de la substance, il est très avantageux que le second orifice ait une section transversale circulaire, en sorte que la substance commence à en tapisser la paroi intérieure en amorçant sa sortie vers l'extérieur, tout en laissant un passage pour les gaz et la vapeur d'eau. On obtient, à cet effet, de bons résultats lorsque le second orifice a un diamètre compris entre 0,7 et 2 mm.To ensure that, during heat treatment, such as pasteurization or sterilization, gases can escape through the second port, while however the latter begins to be filled with the substance, it is very advantageous that the second orifice has a circular cross-section, so that the substance begins to line the interior wall by initiating its exit to the outside, while leaving a passage for gases and water vapor. For this purpose, good results are obtained when the second orifice has a diameter of between 0.7 and 2 mm.
Comme substance, on utilise notamment une colle fusible en une quantité de 10 à 100 mg selon la température de traitement thermique correspondant à une pasteurisation ou à une stérilisation ou à une cuisson. Comme colle fusible, on peut utiliser notamment des colles Hot-melt alimentaires dans les viscosités ci-après.As substance, a fusible adhesive is used in particular in an amount of 10 to 100 mg depending on the heat treatment temperature corresponding to pasteurization or to sterilization or to cooking. As meltable glue, food hot-melt glues can be used in particular in the viscosities below.
On préfère que la substance ait une viscosité de 6 Pas à 200 Pas environ à la température de cuisson. Elle est ainsi apte au mieux à tapisser le second orifice sans être expulsée complètement du logement. Pour faciliter l'effet obtenu lors du refroidissement localisé du logement, il vaut mieux que l'intervalle de température entre le point de fusion et le point de ramollissement de la substance soit inférieur à 15°C et, de préférence, supérieur à 7°C, en sorte que dès que la substance s'est refroidie sensiblement par rapport au reste du récipient, elle prenne un état pâteux quasi-solide et ne puisse pas tomber par le premier orifice et souiller le contenu du récipient, puisque la pression qui règne dans celui-ci est encore suffisante pour repousser la substance. La substance est, de préférence, de qualité alimentaire lorsque le récipient est destiné à cette industrie. Le récipient peut être notamment une boîte de conserve, le logement étant, de préférence, attenant au couvercle et notamment ménagé sur ou sous celui-ci, ou une barquette, le logement pouvant être alors ménagé avantageusement sur un rebord du corps de la barquette recouvert d'un film d'operculage. L'élément peut être rapporté ou, le cas échéant, venir de moulage avec le récipient.It is preferred that the substance has a viscosity of 6 Pas to about 200 Pas at the firing temperature. It is thus best suited to line the second orifice without being completely expelled from the housing. To facilitate the effect obtained during the localized cooling of the housing, it is better that the temperature interval between the melting point and the softening point of the substance is less than 15 ° C and, preferably, greater than 7 ° C, so that as soon as the substance has cooled substantially compared to the rest of the container, it takes a quasi-solid pasty state and cannot fall through the first orifice and contaminate the contents of the container, since the pressure prevailing in it is still enough to repel the substance. The substance is preferably food grade when the container is intended for this industry. The container may in particular be a tin can, the housing preferably being attached to the lid and in particular formed on or under it, or a tray, the housing possibly being advantageously formed on a rim of the body of the covered tray. a sealing film. The element can be added or, if necessary, come from molding with the container.

Le logement 1 communique avec l'intérieur de la boîte par un premier orifice 7 ayant une section de 3 mm2 et avec l'extérieur par un second orifice 8. Ce dernier a une section transversale circulaire d'un diamètre de 1 mm. La viscosité de la substance 4 est de 10 Pas à 110 °C.The can shown in Figure 1 has a

Dès la fin de la cuisson et le début du refroidissement, la résine fusible se fige à nouveau provoquant ainsi la fermeture de la valve fusible (figure 3), empêchant ainsi l'air extérieur de pénétrer dans la barquette.At the end of cooking and the beginning of cooling, the fusible resin freezes again causing the closing of the fusible valve (Figure 3), thus preventing outside air from entering the tray.
