"PROCÉDÉ DE FABRICATION DE CORPS REFROIDISSEDRS""PROCESS FOR MANUFACTURING COOLED BODIES"

Objet de l'inventionSubject of the invention

La présente invention concerne un procédé de fabrication de corps refroidisseurs, du genre de ceux qui comprennent au moins deux parties en matériel métallique accouplées, l'une supérieure et l'autre inférieure, obtenues par une méthode quelconque connue en soi, telle que, par exemple, par emboutissage, et pourvues d'embouchures dont le contour de l'une est légèrement plus grand que celui de l'autre afin de permettre leur emboîtage, de telle façon qu'entre les deux parties se trouve défini un espace fermé herméti¬ quement, contenant un liquide refroidisseur et un élément élastique et/ou flexible d'un matériel conduc- teur thermique, plongés dans le liquide refroidisseur, et qui sont en contact avec le côté interne du corps refroidisseur par une pluralité de points, lesdits corps étant conçus pour être refroidis préalablement et introduits ensuite dans la boisson ou récipient qu'on désire refroidir.The present invention relates to a method of manufacturing coolers, of the type which comprise at least two parts made of coupled metallic material, one upper and the other lower, obtained by any method known per se, such as, by example, by stamping, and provided with mouths, the outline of one of which is slightly larger than that of the other in order to allow them to fit together, so that between the two parts there is defined a hermetic closed space cement, containing a coolant and an elastic and / or flexible element of a thermal conductive material, immersed in the coolant, and which are in contact with the internal side of the cooler body by a plurality of points, said bodies being designed to be cooled beforehand and then introduced into the drink or container to be cooled.

Antécédents de l'inventionHistory of the invention

On connaît depuis longtemps déjà de nombreux systèmes de refroidissement des boissons, dont la plus ancienne est celle qui utilise les cubes de glace ou glaçons. Cette pratique, sans doute encore très étendue et très habituelle, présente des inconvénients impor¬ tants, entre lesquels on peut citer l'inévitable dilu¬ tion des boissons dans lesquelles sont introduits les glaçons.Numerous systems for cooling beverages have been known for a long time, the oldest of which is that which uses ice cubes or icicles. This practice, undoubtedly still very widespread and very usual, has significant drawbacks, between which we can cite the inevitable dilution of the drinks in which the ice cubes are introduced.

Dans le but d'améliorer leur effet refroidissant et aussi pour éliminer le grand inconvénient de dilution des boissons, divers dispositifs refroidisseurs de boissons ont été conçus, entre lesquels on peut citer ceux décrits dans les Brevets PCT No. EP 93/00448 du même demandeur, US 2.152.467, US 1.727.187 et FR 1.322. 928. Dans tous les brevets précités, on décrit des corps métalliques de préférence, remplis d'un liquide refroidisseur, conçus pour être introduits dans un congélateur dans le but de surgeler le liquide refroi¬ disseur, et qu'on plonge ensuite dans la boisson qu'on désire refroidir. Cependant, les corps refroidisseurs décrits dans ces brevets ne sont pas utilisés habituellement dû à leur fabrication très coûteuse, et ce sont pratiquement des objets de luxe hors de portée d'un grand nombre de consommateurs.In order to improve their cooling effect and also to eliminate the great drawback of diluting beverages, various cooling devices drinks have been designed, among which may be mentioned those described in PCT Patents No. EP 93/00448 by the same applicant, US 2,152,467, US 1,727,187 and FR 1,322. 928. In all the aforementioned patents, metallic bodies are preferably described, filled with a cooling liquid, designed to be introduced into a freezer for the purpose of freezing the cooling liquid, and which is then immersed in the drink. we want to cool. However, the cooling bodies described in these patents are not usually used due to their very expensive manufacture, and they are practically luxury items out of the reach of a large number of consumers.

Explication de l'inventionExplanation of the invention

Le procédé de fabrication des corps objet de la présente invention, permet d'obtenir des corps refroi¬ disseurs sans les inconvénients mentionnés antérieure- ment, et qui, parmi d'autres avantages, évite de réali¬ ser les opérations suivantes, qui sont, d'autre part, obligatoires dans tous les corps refroidisseurs obtenus par les procédés connus jusqu'à présent: réalisation dans le récipient d'un orifice de remplissage de liquide refroidisseur; nettoyage de copeaux et d'huile résiduelle qui se produisent pendant l'opération d'usinage des deux parties du récipient; dosage du liquide refroidisseur; - introduction dudit liquide refroidisseur à l'intérieur du récipient; fermeture de l'orifice, par exemple par soudu¬ re; élimination du borax de la soudure, par exe - pie, par réchauffement, avec une solution d'acide sulphurique; soudure entre les deux parties du récipient; etc .The method for manufacturing the bodies which are the subject of the present invention makes it possible to obtain dissipative bodies without the drawbacks mentioned previously, and which, among other advantages, avoids carrying out the following operations, which are, on the other hand, obligatory in all the coolers obtained by the methods known up to now: production in the container of an orifice for filling with coolant; cleaning of chips and residual oil which occur during the machining operation of the two parts of the container; dosing of coolant; - introduction of said coolant inside the container; closing the orifice, for example by soudu¬ re; elimination of borax from the solder, for example, by heating, with a sulfuric acid solution; welding between the two parts of the container; etc.

Il est évident qu'en éliminant toutes ces opéra¬ tions, le coût de la fabrication diminue considéra¬ blement et que, par contre, le rendement de ladite fabrication augmente sensiblement.It is obvious that by eliminating all these opera¬ tions, the cost of manufacture decreases considerably and that, on the other hand, the yield of said manufacture increases appreciably.

Essentiellement, le procédé objet de la présente invention se caractérise par le fait qu'il comprend les étapes de congélation du liquide refroidisseur, ce qui lui permet d' adopter une configuration sensiblement semblable à celle de l'espace intérieur du corps refroi¬ disseur, ayant un volume légèrement inférieur à celui de ce dernier, et de façon qu'au milieu du liquide solidi¬ fié se trouve inclus, en position repliée et sinueuse ledit élément de matériel conducteur thermique; l'in- troduction de la masse congelée de liquide refroidisseur à l'intérieur de la partie inférieure du récipient; et l'emboîtage de l'embouchure de la partie supérieure du corps refroidisseur sur l'embouchure de la partie inférieure, de façon à configurer et fermer le réci- pient.Essentially, the process which is the subject of the present invention is characterized by the fact that it comprises the stages of freezing the coolant, which allows it to adopt a configuration substantially similar to that of the interior space of the cooler body, having a volume slightly less than that of the latter, and so that in the middle of the solidified liquid is included, in the folded and sinuous position, said element of thermal conductive material; the introduction of the frozen mass of coolant inside the lower part of the container; and fitting the mouth of the upper part of the cooling body onto the mouth of the lower part, so as to configure and close the container.

Selon une autre caractéristique de l'invention, les embouchures mutuellement emboîtables des parties du récipient sont pourvues de portions extrêmes qui ont une configuration cylindrique et lisse. Selon une autre caractéristique de l'invention, les portions extrêmes cylindriques et lisses ont, à tempé¬ rature ambiante et avant d'être emboîtées, des dimen¬ sions telles que le périmètre intérieur de la portion extrême de la partie supérieure qui a un plus grand contour, est légèrement inférieur au périmètre extérieur de la portion extrême de la partie inférieure qui a un contour plus petit, tout cela de façon que pour effec¬ tuer l'emboîtage de la portion extrême de la partie supérieure du récipient sur la portion extrême de la partie inférieure, on réalise les opérations suivantes: réchauffement de l'embouchure de la partie supérieure du corps refroidisseur jusqu'à ce que, dû à la dilatation thermique, son périmètre soit légèrement plus grand que celui de la partie inférieure du corps; refroidissement postérieur immédiat de la partie supérieure du corps, afin que son embouchure se contraigne fortement sur celle de la partie inférieure, permettant une fermeture hermétique entre les deux parties.According to another characteristic of the invention, the mutually interlocking mouths of the parts of the container are provided with end portions which have a cylindrical and smooth configuration. According to another characteristic of the invention, the cylindrical and smooth end portions have, at room temperature and before being fitted, dimensions such as the internal perimeter of the end portion of the upper part which has a greater large contour, is slightly less than the outer perimeter of the extreme portion of the lower part which has a smaller contour, all this so that in order to effect the fitting of the extreme portion of the upper part of the container onto the extreme portion from the lower part, the following operations are carried out: heating of the mouth of the upper part of the cooling body until, due to thermal expansion, its perimeter is slightly larger than that of the lower part of the body; immediate posterior cooling of the upper part of the body, so that its mouth is strongly constrained on that of the lower part, allowing a hermetic closure between the two parts.

Selon une autre caractéristique de l'invention, l'opération de réchauffer l'embouchure de la partie supérieure du corps refroidisseur se réalise à une température comprise entre 120 et 200 degrés centigra¬ des.According to another characteristic of the invention, the operation of heating the mouth of the upper part of the cooler body is carried out at a temperature between 120 and 200 degrees centigrade.

Selon une autre caractéristique de l'invention, l'opération de refroidir la partie supérieure du corps refroidisseur s'effectue au moyen d'un jet d'air froid. Selon une autre caractéristique de l'invention, l'emboîtage de la portion extrême de la partie supé¬ rieure du corps sur la portion extrême de la partie inférieure se réalise en appliquant sur les deux parties extrêmes un matériel adhésif hermétique, preféramment transparent, comme par exemple, une résine époxydique, ou tout autre matériel permettant une fermeture herméti¬ que.According to another characteristic of the invention, the operation of cooling the upper part of the cooler body is carried out by means of a jet of cold air. According to another characteristic of the invention, the fitting of the extreme portion of the upper part of the body onto the extreme portion of the lower part is achieved by applying to the two end parts an airtight adhesive material, preferably transparent, such as for example, an epoxy resin, or any other material allowing a hermetic closure.

Selon une autre caractéristique de l'invention, au moins une partie des portions extrêmes cylindriques et lisses est pourvue, du côté opposé à l'autre portion extrême, de nervures annulaires périphériques conçues pour être appliquées à pression sur ledit côté opposé de l'autre portion extrême. Selon une autre caractéristique de l'invention, l'opération de congeler le liquide refroidisseur se réalise dans des moules dont le volume unitaire est tel que la masse congelée obtenue du liquide refroidisseur en état solide comprenant l'élément conducteur thermique introduit au milieu, se transforme plus tard, à tempé¬ rature ambiante, en un volume de liquide refroidisseur inférieur au 95% du volume interne du corps refroi- disseur dans lequel elle a été introduite.According to another characteristic of the invention, at least part of the cylindrical and smooth end portions is provided, on the side opposite to the other end portion, of annular peripheral ribs designed to be applied under pressure on said opposite side of the other extreme portion. According to another characteristic of the invention, the operation of freezing the coolant is carried out in molds whose unit volume is such that the frozen mass obtained from the coolant in solid state comprising the thermal conductive element introduced in the middle, later transforms, at room temperature, into a volume of coolant less than 95% of the internal volume of the cooled body straightener in which it was introduced.

Selon une autre caractéristique de l'invention, comme élément élastique et/ou flexible d'un matériel conducteur thermique, on utilise un ressort hélicoidal métallique, de grande longueur par rapport à son diamè¬ tre.According to another characteristic of the invention, as an elastic and / or flexible element of a thermal conductive material, a metal helical spring is used, of great length relative to its diameter.

Selon une autre caractéristique de l'invention, ledit ressort hélicoidal métallique, juste avant d'être introduit dans le moule de congélation du liquide refroidisseur, est soumis à une torsion hélicoidale sur son propre axe longitudinal, en sens contraire à ses spirales, lui permettant d'adopter une configuration sinueuse d'aspect général également hélicoidal.According to another characteristic of the invention, said metal helical spring, just before being introduced into the freezing mold of the coolant, is subjected to a helical torsion on its own longitudinal axis, in the opposite direction to its spirals, allowing it to adopt a sinuous configuration of general aspect also helical.

Description détaillée des dessinsDetailed description of the drawings

Dans les dessins annexés, on illustre, à titre d'exemple non limitatif, quelques formes de réalisation du procédé objet de l'invention.In the accompanying drawings, there are illustrated, by way of non-limiting example, some embodiments of the process which is the subject of the invention.

Les Figs. 1 à 3 montrent trois vues partielles, en plan et en section, d'une première forme de réalisation d'un corps refroidisseur selon le procédé de l'inven¬ tion; les Figs. 4 et 5 sont des vues en plan et en section, d'un corps refroidisseur selon l'invention, contenant le liquide congelé et non congelé, respective¬ ment; la Fig. 6 est aussi une vue partielle, en plan et en section, d'une deuxième forme de réalisation d'un corps refroidisseur selon le procédé de l'invention; et les Figs. 7 et 8 montrent aussi deux vues partie¬ lles, en plan et en section, d'une troisième forme de réalisation d'un corps refroidisseur selon le procédé de l' invention.Figs. 1 to 3 show three partial views, in plan and in section, of a first embodiment of a cooling body according to the method of the invention; Figs. 4 and 5 are plan and section views of a cooling body according to the invention, containing the frozen and non-frozen liquid, respectively; Fig. 6 is also a partial view, in plan and in section, of a second embodiment of a cooler body according to the method of the invention; and Figs. 7 and 8 also show two partial views, in plan and in section, of a third embodiment of a cooling body according to the method of the invention.

Dans lesdits dessins, on peut apprécier que le corps refroidisseur obtenu selon le procédé objet de la présente invention comprend deux parties accouplées, en matériel métallique, une partie supérieure 2 et une partie inférieure 3, obtenues d'une manière quelconque connue en soi, par exemple, par emboutissage.In said drawings, it can be appreciated that the cooler body obtained according to the process which is the subject of the present invention comprises two coupled parts, made of metallic material, an upper part 2 and a lower part 3, obtained in any manner known per se, for example, by stamping.

Chacune des parties 2 et 3 est pourvue d'une embouchure (4, 5), le contour de l'embouchure 2 de la partie supérieure 2 étant légèrement plus grand que le contour de l'embouchure 5 de la partie inférieure 3.Each of the parts 2 and 3 is provided with a mouth (4, 5), the contour of the mouth 2 of the upper part 2 being slightly larger than the contour of the mouth 5 of the lower part 3.

Entre les deux parties 2 et 3, se trouve défini, lorsqu'elles sont emboîtées, un espace fermé hermétique¬ ment, contenant un liquide refroidisseur 6 et un élément 7 élastique et/ou flexible (Fig. 5) d'un matériel conducteur thermique, plongé dans le liquide refroi¬ disseur 6 et qui est en contact avec le côté interne du récipient 1 par une pluralité de points.Between the two parts 2 and 3, there is defined, when they are fitted together, a hermetically closed space containing a coolant 6 and an elastic and / or flexible element 7 (Fig. 5) of a thermal conductive material , immersed in the refroid¬ disseur liquid 6 and which is in contact with the internal side of the container 1 by a plurality of points.

Comme il a déjà été décrit antérieurement, les corps refroidisseurs 1 fabriqués selon l'invention, sont conçus de façon conventionnelle pour être refroidis préalablement, préféramment jusqu'à congélation du liquide refroidisseur 6, et les introduire plus tard dans la boisson ou récipient qu'on désire refroidir. Pour fabriquer un corps refroidisseur 1 selon la présente invention, en premier lieu on effectue préala¬ blement une congélation du liquide refroidisseur 6, ce qui se réalise dans des moules conventionnels, non représentés sur les dessins, dont le volume unitaire est tel que la masse congelée obtenue du liquide refroidis¬ seur en état solide (Fig. 4) se transforme ensuite en un volume de liquide ref oidisseur 6 inférieur à 95% du volume interne du corps refroidisseur 1 dans lequel elle a été introduite (Fig. 5) . Dans chaque moule de congélation de liquide refroi¬ disseur 6, on introduit un élément élastique 7 d'un matériel conducteur thermique, lequel est de préférence constitué par un ressort hélicoidal métallique de grande longueur. Avantageusement, ledit ressort hélicoidal métallique 7 est introduit à l'intérieur du moule en saisissant ses extrémités et en effectuant une torsion longitudinale en sens contraire à ses spirales, ce qui - 1 - empêche l' intercalage desdites espirales. Par consé¬ quent, après la congélation, le ressort 7 reste intro¬ duit au milieu du liquide refroidisseur 6, congelé, plié sur lui-même en plusieurs doublures qui créent, à leur tour, une pluralité de points de contacts mutuels et avec le côté interne du récipient.As has already been described previously, the cooling bodies 1 manufactured according to the invention are conventionally designed to be cooled beforehand, preferably until the coolant 6 is frozen, and introduce them later in the drink or container than we want to cool. To manufacture a cooling body 1 according to the present invention, firstly a freezing of the cooling liquid 6 is carried out beforehand, which is carried out in conventional molds, not shown in the drawings, the unit volume of which is such that the mass frozen product obtained from the liquid cooler in solid state (Fig. 4) then turns into a volume of coolant liquid 6 less than 95% of the internal volume of the cooler body 1 into which it has been introduced (Fig. 5). In each mold for freezing the refroid¬ liquid 6, an elastic element 7 of a thermal conductive material is introduced, which is preferably constituted by a metal helical spring of great length. Advantageously, said metal helical spring 7 is introduced inside the mold by grasping its ends and performing a longitudinal twist in the opposite direction to its spirals, which - 1 - prevents the intercalation of said spirals. Consequently, after freezing, the spring 7 remains introduced into the middle of the coolant 6, frozen, folded over itself in several linings which in turn create a plurality of points of mutual contact and with the inner side of the container.

Préféramment, le matériel dont est constitué ledit ressort métallique est du cuivre recouvert d'une couche de quelques microns d'argent ou de nickel, bien que ce revêtement puisse être n'importe quel matériel métalli¬ que résistant à l'oxydation et qui soit un bon conduc¬ teur thermique.Preferably, the material of which the said metal spring is made is copper covered with a layer of a few microns of silver or nickel, although this coating can be any metalli¬ that oxidation resistant material which is a good thermal conductor.

Grâce à l'incorporation dudit élément flexible de nouvelle constitution selon l'invention, l'utilisation du corps refroidisseur obtenu par le procédé de l'inven¬ tion produit une plus grande chute de température dans les boissons dans lesquelles est introduit le corps refroidisseur, et réduit sensiblement le temps nécessai¬ re pour atteindre le point le plus bas de température de la boisson.Thanks to the incorporation of said flexible element of new constitution according to the invention, the use of the cooling body obtained by the process of the invention produces a greater temperature drop in the drinks into which the cooling body is introduced, and significantly reduces the time required to reach the lowest temperature point of the drink.

Une fois congelé, on place le liquide refroidisseur 6, avec l'élément 7 introduit au milieu, dans la partie inférieure 3 du corps refroidisseur 1. Dans une premiè¬ re forme de réalisation du procédé selon l'invention, l'embouchure 5 (Fig. 1) de la partie inférieure 3 a un périmètre externe qui est quelques centièmes de mil¬ limètres plus grand que le périmètre interne de l'embou¬ chure 4 de la partie supérieure 2, lorsque les deux parties 2 et 3 se trouvent à la même température. Lesdites embouchures 4 et 5 sont définies par les portions extrêmes (rebords d'union) 7 et 9 cylindriques et lisses de la paroi de chaque partie 2 et 3 du corps refroidisseur 1.Once frozen, the coolant 6 is placed, with the element 7 introduced in the middle, in the lower part 3 of the cooler body 1. In a first embodiment of the method according to the invention, the mouth 5 ( Fig. 1) of the lower part 3 has an external perimeter which is a few hundredths of a milimeter larger than the internal perimeter of the mouthpiece 4 of the upper part 2, when the two parts 2 and 3 are at the same temperature. Said mouths 4 and 5 are defined by the cylindrical and smooth end portions (union edges) 7 and 9 of the wall of each part 2 and 3 of the cooler body 1.

Postérieurement, on réchauffe la partie supérieure 2 du corps refroidisseur 1, préféramment dans la zone de l'embouchure 4, à une température au-dessus du point de recristallisation du matériel qui constitue le corps 1, jusqu'à ce que le diamètre de ladite embouchure 4 augmente de façon à pouvoir emboîter la partie supérieu¬ re 2 sur la partie inférieure 3 (Fig. 2) , et juste après on procède à refroidir la partie supérieure 2, par exemple au moyen d'un jet d'air froid.Subsequently, the upper part 2 of the cooler body 1 is heated, preferably in the region of the mouth 4, to a temperature above the recrystallization point of the material which constitutes the body 1, until the diameter of said mouth 4 increases so as to be able to fit the upper part 2 onto the lower part 3 (FIG. 2), and just afterwards the upper part 2 is cooled, for example by means a jet of cold air.

Dans l'opération de refroidissement de la partie supérieure 2, il se produit simultanément un effet double: lorsque les deux embouchures 4 et 5 entrent en contact par contraction de la partie supérieure 2, l'embouchure 5, plus froide, se réchauffe et l'embouchu¬ re 4, plus chaude, se refroidit, ce qui permet d'attein¬ dre un équilibre thermique entre les deux embouchures 4 et 5 lesquelles se serrent fortement l'une contre l'au¬ tre, tout en réalisant une fermeture hermétique du corps refroidisseur 1 avant que se produise la décongélation du liquide refroidisseur 6.In the cooling operation of the upper part 2, a double effect occurs simultaneously: when the two mouths 4 and 5 come into contact by contraction of the upper part 2, the mouth 5, which is cooler, heats up and l 'mouthpiece 4, warmer, cools, which allows to reach a thermal equilibrium between the two mouths 4 and 5 which tighten tightly against one another, while achieving a hermetic closure of the cooling body 1 before the thawing of the cooling liquid 6 takes place.

Dans une deuxième forme de réalisation de l'inven¬ tion, illustrée sur la Fig. 6, les portions extrêmes 8 et 9 sont opposées avec interposition d'un matériel adhésif hermétique 10, de préférence transparent, comme par exemple, une résine époxydique ou tout autre maté¬ riel permettant une fermeture hermétique.In a second embodiment of the invention, illustrated in FIG. 6, the end portions 8 and 9 are opposite with the interposition of an airtight adhesive material 10, preferably transparent, such as, for example, an epoxy resin or any other material allowing a hermetic closure.

Sur les Figs. 7 et 8 il est illustré une troisième forme de réalisation de l'invention, dans laquelle on peut observer que le côté externe de la portion extrême 9 de l'embouchure 5 de la parte inférieure 3 du corps est pourvue d'une pluralité de nervures 11, conçues pour être appliquées à pression sur le côté interne de la portion extrême 8 de la partie supérieure 2 du corps refroidisseur, permettant en même temps la fermeture hermétique du récipient 1.In Figs. 7 and 8 a third embodiment of the invention is illustrated, in which it can be observed that the external side of the extreme portion 9 of the mouth 5 of the lower part 3 of the body is provided with a plurality of ribs 11, designed to be applied under pressure to the internal side of the end portion 8 of the upper part 2 of the cooler body, at the same time allowing the container 1 to be hermetically sealed.

Le procédé de fabrication du corps refroidisseur objet de la présente invention peut être utilisé avec succès, non seulement pour les corps refroidisseurs, mais il peut être aussi très adéquat pour être appliqué dans d'autres industries, comme par exemple, dans l'industrie alimentaire et l'industrie pharmaceutique. La nature de l'invention ainsi que son mode d'emploi ayant été suffisamment décrits, on fait obser¬ ver que l'invention peut être soumise à des variations de détails, toutefois que son principe fondamental ne soit pas altéré ou modifié. The process for manufacturing the cooling body which is the subject of the present invention can be used successfully, not only for the cooling bodies, but it can also be very suitable for application in other industries, such as, for example, in the food industry. and the pharmaceutical industry. The nature of the invention and its instructions having been sufficiently described, it is observed that the invention may be subject to variations in details, however that its fundamental principle is not altered or modified.
