Abstract

A plastic lattice comprising an arbitrary number of cooling elements (1) made of a sealed plastic shell (2) containing a eutectic solution or gel, joined together by X-shaped connectors (7), and arranged to form an open plastic lattice. Free interstices (8) are provided around each cooling element (1) for easy cutting of the device. Plastic straps (9) or the like are inserted through said interstices (8) so that a user can easily enlarge the device by simply linking together groups of cooling elements (1). The lattice is particularly suitable for covering, sheathing or wrapping perishable foods requiring refrigeration.

Description

Treillis Plastique Réfrigérant Plastic Cooling Mesh
La présente invention relève des échangeurs de chaleur en ce qu'elle concerne un dispositif pouvant,après avoir été préalablement congelé, réfrigérer des appareils,des matières,ou des denrées,et notamment des denrées périssables,detoutes formes et dimensions .The present invention relates to heat exchangers in that it relates to a device which, after having been previously frozen, refrigerates devices, materials, or foodstuffs, and in particular perishable foodstuffs, of any shape and size.
Il existe sur le marché des produits destinés à cet usage,mettant à profit les propriétés eutectiques de certaines solutions liquides ou gélifiées conditionnées sous enveloppe étanche de matière plastique semi-rigide ou souple . Certains de ces produits se présentent sous la forme de volumes indéformables,par exemple:briquettes de glace"sèche" d'autres,sous la forme d'une plaque de faible épaisseur,plane ou alvéolée de manière à répartir le réfrigérant inclus en volumes indépendants, pouvant être moulée à la forme des objets à refroidir,après avoir été congelée. Les inconvénients majeurs de ces dispositifs,pour l'utilisateur résultent de leurs dimensions fixes; s'il est parfois possible de découper certains de ces dispositifs,et ce avec précaution pour ne pas percer l'enveloppe du réfrigérant au risque, d'en perdre,il est souvent très malaisé de les agrandir sans avoir recours à un quelconque outil.There are products on the market for this use, taking advantage of the eutectic properties of certain liquid or gelled solutions packaged in a sealed envelope of semi-rigid or flexible plastic. Some of these products are in the form of non-deformable volumes, for example: briquettes of "dry" ice others, in the form of a thin plate, flat or honeycombed so as to distribute the refrigerant included in independent volumes , which can be molded to the shape of the objects to be cooled, after being frozen. The major drawbacks of these devices for the user result from their fixed dimensions; if it is sometimes possible to cut out some of these devices, and this with care so as not to puncture the envelope of the refrigerant at the risk of losing them, it is often very difficult to enlarge them without having to use any tool.
La présente invention se propose donc de pallier ces inconvénients en offrant à ses utilisateurs un dispositif réfrigérant aisément déformable une fois congelé,pouvant être facilement'découpé sans précautions particulières et pouvant être agrndi à volonté par une simple opération ne nécesstant aucun outil.The present invention proposes to overcome these disadvantages by offering its users an easily deformable chiller once frozen, can be easily 'cut out without special precautions and can be agrndi at will by a simple operation nécesstant tools.
A cet effet,un dispositif selon l'invention comporte un nombre indéfini d'enveloppes plastiques étanches,contenant une solution ou un gel eutectique usuel,ci-après nommées:"éléments réfrigérants", reliées entre elles par des liaisons cruciformes en nombre strictement nécessaire et suffisant,et agencées entre elles de manière à donner au dispositif,selon une première caractéristique,la configuration d'un treillis plastique ajouré. Chaque élément réfrigérant du dispositif est séparé des éléments réfrigérantsvoisins par un intervalle vide d'une largeur suffisante pour permettre le passage .d'un lien plastique quelconque,non décrit dans la présente demande,permettant de relier entre eux plusieurs éléments ou groupes d'éléments réfrigérants par simple ligature. Ces intervalles vides déterminent d'autre part les lignes selon lesquelles le dispositif peut être découpé.To this end, a device according to the invention comprises an indefinite number of watertight plastic envelopes, containing a usual eutectic solution or gel, hereinafter called: "cooling elements", connected together by cruciform bonds in strictly necessary numbers. and sufficient, and arranged between them so as to give the device, according to a first characteristic, the configuration of an openwork plastic mesh. Each refrigerating element of the device is separated from the neighboring refrigerating elements by an empty gap of sufficient width to allow the passage of any plastic link, not described in the present application, making it possible to connect between them several elements or groups of refrigerating elements by simple ligation. These empty intervals also determine the lines along which the device can be cut.
Il apparait ainsi que le présent dispositif réfrigérant peut être aisément courbé,plié,et qu'en combinant ligatures,déformations plastiques et découpes,il peut être conformé selon la plupart des enveloppes de volumes permises aux "plaques minces",et ce,sans limitation de taille,pour assurer la plus grande surface de contact possible entre les éléments réfrigérants et les objets ou denrées à refroidir.It thus appears that the present refrigerating device can be easily curved, folded, and that by combining ligatures, plastic deformations and cutouts, it can be shaped according to most envelopes of volumes allowed for "thin plates", without limitation. in size, to ensure the greatest possible contact surface between the cooling elements and the objects or foodstuffs to be cooled.
Selon des modes particuliers de réalisation: Le volume des éléments réfrigérants peut être intégralement d'un côté du plan défini par les liaisons entre éléments réfrigérants; Le volume des éléments réfrigérants peut être également ou non réparti de part et d'autre du plan défini par les liaisons entre éléments réfrigérants;According to particular embodiments: The volume of the cooling elements can be entirely on one side of the plane defined by the connections between cooling elements; The volume of the cooling elements can be equally or not distributed on either side of the plane defined by the connections between cooling elements;
Les éléments réfrigérants constitutifs du dispositif peuvent ne pas être identiques en volumes et en formes.The refrigerating elements making up the device may not be identical in volume and shape.
Les dessins annexés illustrent deux modes préférentiels de réalisation de l'invention,sans être limitatifs pour l'invention.The accompanying drawings illustrate two preferred embodiments of the invention, without being limiting for the invention.

A titre d'exemple non limitatif,un élément réfrigérant aura des dimensions de l'ordre de 10 centimèters pour la longueur, 3 centimètres pour la largeur et 2.5 centimètres pour l'épaisseur; les liaisons cruciformes détermineront des intervalles vides d'une largeur de l'ordre de 5 millimètres entre les éléments réfrigérants.By way of nonlimiting example, a refrigerating element will have dimensions of the order of 10 centimeters for the length, 3 centimeters for the width and 2.5 centimeters for the thickness; the cruciform connections will determine empty intervals of a width of the order of 5 millimeters between the refrigerating elements.
