Description

La presente invention se rapporte a un sac isotherme destine au transportThe present invention relates to an insulated bag for transport

d'au moins un article devant titre maintenu a temperature ambiante. On connait deja des conteneurs isothermes permettant de transporter des articles froids ou chauds tout en les maintenant a temperature.  at least one article to be maintained at room temperature. Isothermal containers are already known for transporting cold or hot items while maintaining them at a temperature.

Ces conteneurs peuvent titre schematiquement repartis en deux categories, a savoir d'une part, les conteneurs rigides du type glaciere, et d'autre part, les conteneurs souples ou sacs isothermes. Par sacs isothermes, on entend des sacs comprenant un revetement isolant pour la conservation de produits frais dans des conditions 10 normales d'utilisation. Les sacs isothermes traditionnels comprennent deux parois isothermes reliees rune a I'autre, des moyens de fermeture, et des moyens de prehension pour le transport. Les moyens de fermeture peuvent par exemple consister en un 15 rabat solidaire de rune des deux parois apte a venir se fixer dans I'autre paroi par I'intermediaire de clips ou boutons-pression. Cependant, un sac isotherme presente Ies inconvenients suivants. Tout d'abord, la matiere autour de chaque bouton-pression a tendance a se deteriorer relativement rapidement au fil du temps du fait des multiples ouvertures/fermetures du rabat, et le risque 20 d'arrachement est donc important. De plus, la fermeture est difficile a realiser par I'utilisateur, tout particulierement lorsque ce dernier a fait de nombreuses courses et se retrouve avec plusieurs sacs, isothermes ou non, a transporter. Un autre exemple de dispositif de fermeture de sac isotherme est decrit dans la demande de brevet frangais FR 2 828 677, et comprend un 25 premier profile muni d'une poignee et fixe le long d'une des deux parois du cote de I'ouverture du sac, et un deuxieme profile fixe, par une portion de sa surface externe, le long de I'autre paroi egalement du cote de I'ouverture, (edit deuxieme profile etant equipe d'un trou dans lequel la poignee peut venir s'inserer et demeurer bloquer dans cette position. Un sac isotherme ainsi 30 equipe fonctionne parfaitement, mais son coOt de revient est relativement eleve et rend donc son application delicate dans le cadre de la tres grande distribution. La presente invention a pour but de remedier aux inconvenients precedemment evoques, et consiste pour cela en un sac isotherme destine au 35 transport d'au moins un article devant titre maintenu a temperature, (edit sac isotherme comprenant notamment deux parois isothermes reliees rune a I'autre, des moyens de fermeture, et des moyens de prehension, caracterise en ce que les moyens de fermeture sont realisees a ('aide d'au moins un ruban de tissu a bouclettes equipant rune des deux parois isothermes et etant apte a cooperer avec au moins un ruban de tissu a crochets equipant I'autre paroi isotherme. Ainsi, le fait de prevoir une fermeture a ('aide d'un ruban a bouclettes cooperant avec un ruban a crochets permet d'obtenir une fermeture facile et soignee. De plus, une telle fermeture peut facilement s'etendre sur toute la longueur du sac et, d'une part, ameliore donc la repartition des efforts lors d'une ouverture en ecartant les parois du sac, d'autre part, limite la circulation d'air ce qui reduit les pertes thermiques. Par ailleurs, un tel moyen de fermeture permet une eventuelle reouverture partielle afin de glisser un ou plusieurs autres articles sans rouvrir totalement le sac. II convient egalement de noter qu'un tel sac isotherme ne comprend aucune partie rigide et peut donc titre facilement plie lorsque inutilise. De maniere preferentielle, chaque ruban de tissu a bouclettes et chaque ruban de tissu a crochets correspondant sont disposes en bordure de ('ouverture. Avantageusement, le sac isotherme selon ('invention comprend un 20 unique ruban de tissu a bouclettes s'etendant sur toute la longueur de ('ouverture du sac. Avantageusement encore, le sac isotherme selon ('invention comprend un unique ruban de tissu a crochets s'etendant sur toute la longueur de ('ouverture du sac. 25 Preferentiellement, deux paves de fermeture espaces d'une distance sensiblement egale a Ia longueur de ('ouverture sont menages dans les parois au voisinage de ladite ouverture. De cette maniere, I'utilisateur obtient une meilleure prise et peut fermer plus facilement le sac. Preferentiellement encore, les moyens de prehension sont des 30 anses souples. Ainsi, le sac isotherme ne comprend aucune partie rigide et peut titre totalement plie. L'invention sera mieux comprise a ('aide de la description detainee qui est exposee ci-dessous en regard du dessin annexe dans Iequel : La figure 1 est une vue en perspective avant d'un sac selon 35 ('invention ouvert. La figure 2 est une vue partielle de face du sac de la figure 1 ferme.  These containers can be schematically divided into two categories, namely, on the one hand, the rigid containers of the ice-cream type, and on the other hand, the flexible containers or insulated bags. Isothermal bags are bags comprising an insulating coating for the preservation of fresh products under normal conditions of use. The traditional insulated bags comprise two insulated walls connected to each other, closure means, and means of gripping for transport. The closure means may for example consist of a flap integral with one of the two walls adapted to be fixed in the other wall by means of clips or snaps. However, an insulated bag has the following disadvantages. First, the material around each snap tends to deteriorate relatively rapidly over time due to multiple flap openings / closures, and the risk of tearing is therefore significant. In addition, the closure is difficult to achieve by the user, especially when the latter has done many races and is left with several bags, insulated or not, to carry. Another example of an insulated bag closure device is described in the French patent application FR 2 828 677, and comprises a first profile provided with a handle and fixed along one of the two walls of the opening side. of the bag, and a second fixed profile, by a portion of its outer surface, along the other wall also on the side of the opening, (edit second profile being equipped with a hole in which the handle can come s' insert and remain locked in this position An isothermal bag thus equipped works perfectly, but its cost of return is relatively high and thus makes its application delicate in the context of the very large distribution.The present invention aims to remedy the drawbacks. previously evokes, and is for this purpose in an isothermal bag for the transport of at least one article to title held at temperature, (edit isothermal bag including including two isothermal walls connected to each other, means closure means, and gripping means, characterized in that the closing means are made with the aid of at least one ribbon of loop fabric equipped rune two isothermal walls and being adapted to cooperate with at least one ribbon fabric with hooks equipping the other isothermal wall. Thus, providing a closure using a loop ribbon cooperating with a hook tape provides an easy and neat closure, and such a closure can easily extend the full length of the closure. bag and, on the one hand, improves the distribution of forces during an opening by removing the walls of the bag, on the other hand, limits the air flow which reduces heat losses. closure allows a possible partial reopening in order to slide one or more other articles without completely reopening the bag.It should also be noted that such an insulated bag does not include any rigid part and can therefore easily folded title when not used. each looped fabric ribbon and each corresponding hook fabric ribbon are disposed at the edge of the opening Advantageously, the insulated bag according to the invention comprises a single looped fabric ribbon extending through the entire length of the opening of the bag. Advantageously, the isothermal bag according to the invention comprises a single hooked fabric ribbon extending over the entire length of the opening of the bag. In this way, the user obtains a better grip and can more easily close the bag, and preferentially the gripping means are flexible handles. The invention will be better understood from the following detailed description with reference to the accompanying drawings in which: Figure 1 is a perspective view in front of Figure 2 is a fragmentary front view of the bag of Figure 1 closes.

La figure 3 est une vue partielle en coupe transversale selon la ligne III-III du sac de la figure 2. La figure 4 est une vue partielle en coupe transversale selon la ligne IV-IV du sac de la figure 2.  FIG. 3 is a partial view in cross-section along the line III-III of the bag of FIG. 2. FIG. 4 is a partial view in transverse section along the line IV-IV of the bag of FIG.

Un sac isotherme 1 selon I'invention est realise a partir d'une feuille 2 d'un materiau isotherme multicouche repliee en deux sur elle-meme de maniere a constituer deux parois 2a, soudees entre elles sur leur longueur pour former deux bordures later-ales 3. La feuille 2 de materiau isotherme realise ainsi un sac presentant, d'une part, un fond 4, et d'autre part, une ouverture 5.  An isothermal bag 1 according to the invention is made from a sheet 2 of a multilayer isothermal material folded in two on itself so as to form two walls 2a, welded together along their length to form two lateral edges. 3. The sheet 2 of isothermal material thus produces a bag having, on the one hand, a bottom 4 and, on the other hand, an opening 5.

Plus precisement, le sac isotherme 1 presente au niveau de I'ouverture 5 des rebords 6, 7 realises chacun a partir d'une extremite 8 de la feuille 2 de materiau isotherme repliee sur elle-meme vers I'interieur du sac puis soudee a la paroi 2a correspondante. Ceci apporte une plus grande solidite aux rebords 6, 7.  More specifically, the insulated bag 1 has at the opening 5 flanges 6, 7 each made from an end 8 of the sheet 2 of isothermal material folded on itself towards the inside of the bag and then welded to the corresponding wall 2a. This brings greater strength to the edges 6, 7.

Une anse 9 souple est rattachee par soudure dans la zone centrale de chacun des rebords 6, 7. Le sac isotherme 1 est equipe d'un systeme de fermeture comportant une bande de tissu a crochets 10 fixee sur toute la longueur du rebord 6 vers I'interieur du sac isotherme 1 et apte a cooperer avec une bande de tissu a bouclettes 11 fixee sur toute la longueur du rebord 7 en regard du rebord 6. Les rebords 6, 7 se rejoignent de chaque cote du sac isotherme 1 pour former des paves de fermeture 14, 15 destines a faciliter la prise en main et augmenter Iocalement la rigidite de maniere a ameliorer la fermeture.  A flexible loop 9 is joined by welding in the central zone of each of the flanges 6, 7. The isothermal bag 1 is equipped with a closure system comprising a hooked fabric strip 10 fixed over the entire length of the flange 6 to I interior of the insulated bag 1 and adapted to cooperate with a band of loop fabric 11 fixed over the entire length of the flange 7 opposite the rim 6. The flanges 6, 7 are joined on each side of the insulated bag 1 to form paves closure 14, 15 to facilitate the grip and increase içalement rigidity so as to improve the closure.

Chaque pave de fermeture 14, 15 est realise en fondant ensemble localement sur toute leur epaisseur les rebords 6, 7 de maniere a former une zone rigide. Chaque pave de fermeture 14, 15 est realise a proximite d'une bordure laterale 3 du sac isotherme 1, et les deux paves de fermeture 14, 15 sont espaces entre eux d'une distance sensiblement egale a la distance de I'ouverture 5.  Each closing block 14, 15 is made by melting together locally over their entire thickness the flanges 6, 7 so as to form a rigid zone. Each closing block 14, 15 is made close to a lateral edge 3 of the isothermal bag 1, and the two closing plates 14, 15 are spaced from each other by a distance substantially equal to the distance from the opening 5.

Un utilisateur souhaitant utiliser un sac isotherme 1 selon ('invention pourra fermer facilement ce sac en le saisissant par les paves de fermeture 14, 15 et, les pouces ainsi positionnes, en ecartant lesdits paves de fermeture 14, 15 I'un de I'autre de maniere a rapprocher la bande de tissu a bouclettes 11 de la bande de tissu a crochets 10 pour Ies tendre et les plaquer ('une contre I'autre.  A user wishing to use an insulated bag 1 according to the invention can easily close this bag by grasping it by the closure slats 14, 15 and the thumbs thus positioned, by moving said closing slats 14, 15 away from one another. Another manner is to bring the loop web 11 closer to the hook web 10 to tension and press them together.

De cette maniere, I'utilisateur opere une fermeture facile et rapide du sac ne necessitant pas d'attention particuliere. Bien que ('invention ait ete decrite en liaison avec des exemples particuliers de realisation, it est bien evident qu'elle n'y est nullement Iimitee et qu'elle comprend tous les equivalents techniques des moyens decrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de ('invention.  In this way, the user operates a quick and easy closure of the bag not requiring special attention. Although the invention has been described in connection with particular embodiments, it is evident that it is in no way limited and that it includes all the technical equivalents of the means described and their combinations if these fall within the scope of the invention.
