Abstract

The curtain cover is used to close conditioned containers (10) for foodstuffs, such as refrigerated counters. Said cover comprises a flexible screen (11) formed by spontaneous folding in a roll and whose terminal edges are fitted with semirigid battens (13, 14), a first batten (13) which is designed to fix the cover permanently to one side of the access opening of the container (10), and a second batten (14) designed to fix the cover removably to the other side of the opening.

Description

Il est connu de conserver des denrées alimentaires dans des conteneurs frigorifiques, même aux endroits où ces denrées sont exposées au public pour la vente. It is known to keep foodstuffs in refrigerated containers, even in places where these foodstuffs are displayed to the public for sale.

Pour cette raison, il s'est répandu des conteneurs de ce type qui ont en eux-mêmes une configuration adaptée pour limiter les échanges thermiques avec l'environnement, même lorsqu'ils sont maintenus ouverts, afin de donner aux acheteurs nn acces plus facile aux produits exposés. For this reason, it has spread containers of this type which have in themselves a configuration adapted to limit heat exchanges with the environment, even when they are kept open, in order to give buyers easier access. exposed products.

Par exemple , les banques pour la conservation des produits surgelés présentent la configuration de puits, de sorte que la stratification naturelle de l'air contribue à maintenir dans leur partie inférieure la basse température voulue. For example, the banks for the storage of frozen products present the configuration of wells, so that the natural stratification of the air helps to maintain in their lower part the desired low temperature.

Toutefois, des considérations évidentes de limitationa de l'énergie consommée dans les installations frigorifiques ainsi que la considération du fait qu'il peut devenir nécessaire de renforcer l'isolation thermique dans le cas d'une interruption momentanée de la distribution de l'éner- gie par le réseau, rendent avantageuse la possibilité de fermer temporairement ces conteneurs réfrigérés. However, obvious considerations of limitation of the energy consumed in the refrigeration installations as well as the consideration of the fact that it may become necessary to reinforce the thermal insulation in the event of a temporary interruption of the distribution of the energy. network, make it advantageous to temporarily close these refrigerated containers.

L'invention se propose d'atteindre ce but d'une façon rationnelle et avantageuse on réalisant un écran de recou- vrement souple constitué par une feuille de matière plastique, en particulier de polyester transparent, formée de façon à se replier spontanément en rouleau et dont les bords extrêmes sont munis de tringles semi-rigides, l'une de ces tringles étant destinée à assurer la fixation permanente d'un coté de la bonche du conteneur réfrigéré et l'autre à assurer la fixation amovible de l'autre côte de la bouche du conteneur
Une forme de réalisation de l'invention sera à présent décrite à titre d'exemple non limitatif en regard des des- sins annexés sur lesquels
la figure 1 est un schéma d'un conteneur réfrigéré équipé d'une bâche suivant l'invention
les figures 2 et 3 sont des vues partielles d'une couverture qui montrent respectivement cette bâche à l'état déployé et à l'état enroulé
la figure 4 est une vue analogue à la figure 2.
The invention proposes to achieve this object in a rational and advantageous way by providing a flexible covering screen constituted by a sheet of plastic, in particular transparent polyester, formed so as to spontaneously fold up in a roll and whose extreme edges are provided with semi-rigid rods, one of these rods being intended to ensure the permanent fixing on one side of the bonche of the refrigerated container and the other to ensure the removable fixing of the other side of container mouth
An embodiment of the invention will now be described by way of non-limiting example with reference to the accompanying drawings in which
Figure 1 is a diagram of a refrigerated container equipped with a sheet according to the invention
Figures 2 and 3 are partial views of a cover which respectively show this cover in the deployed state and in the rolled up state
FIG. 4 is a view similar to FIG. 2.

Ainsi qu'on l'a représenté sur les figures 1, 2 et 3, une bache désignée dans son ensemble par la référence 11 est montée sur un conteneur réfrigéré normal 10 qui est ouvert au niveau de sa face supérieure. As shown in Figures 1, 2 and 3, a sheet designated as a whole by the reference 11 is mounted on a normal refrigerated container 10 which is open at its upper face.

Comme on peut mieux le voir sur les figures 2 et 3, cette bâche est formée d'un film 12 de polyester d'unie épaisseur adéquate, par exemple d'environ 1 ou 2 dixièmes de millimètre, de manière à avoir une consistance suffisante pour les buts qui seront exposés ci-après. As can best be seen in FIGS. 2 and 3, this sheet is formed from a polyester film 12 of plain polyester of adequate thickness, for example around 1 or 2 tenths of a millimeter, so as to have a sufficient consistency for the purposes which will be set out below.

La matière en film considérée est traitée, suivant une technique bien connue des fabricants 9e ce type de matière, de manière à prendre spontanément une forme étroitement enroulée ; évidemment, pliée en deux, elle forme an seul rouleau à double épaisseur. The film material under consideration is treated, according to a technique well known to the manufacturers of this type of material, so as to spontaneously take a tightly wound form; obviously, folded in half, it forms a single double thickness roll.

Cette disposition est obtenue en plaçant le film, préalablement mis dans sa position enroulée, dans un four chauffé à une température adéquate, température qui dépend de la nature de la matière et du temps de traitement. This arrangement is obtained by placing the film, previously put in its rolled up position, in an oven heated to an adequate temperature, a temperature which depends on the nature of the material and the treatment time.

Aux deux extrémités du film sont fixées des tringles rigides ou semi-rigides 13 et 14 respectivement. Rigid or semi-rigid rods 13 and 14 respectively are attached to the two ends of the film.

La tringle 13 est fixée de façon sensiblement permanente (par exemple au moyen de vis), à proximité d'un bord de la bouche d'un conteneur réfrigéré ; l'autre tringle 14 porte des moyens d'accrochage traditionnels, qu 7 on a omis de décrire dans le présent mémoire parce qu'ils sont entièrement connus, et qui peuvent être constitués par des crochets, des boutons pression ou des éléments équivalents adaptés pour entre accouplés à des éléments complémentaires prévins sur le bord correspondant de la bonche du conteneur,-pour maintenir la boche dans la position de la figure 2, tendue en surmontant la force spontanée qui tend à réenrouler le film en un rouleau. The rod 13 is fixed substantially permanently (for example by means of screws), near an edge of the mouth of a refrigerated container; the other rod 14 carries traditional hooking means, which we have omitted to describe in the present specification because they are entirely known, and which can be constituted by hooks, snaps or equivalent elements suitable for between coupled to complementary elements previns on the corresponding edge of the bonche of the container, -to maintain the boche in the position of figure 2, stretched overcoming the spontaneous force which tends to rewind the film in a roll.

Il est évident que le film peut être enroulé de différentes façons, par exemple en rouleau simple autour de la tringle mobile 14, comme on l'a représenté sur la figure .4, bien que la réalisation des figures 1 à 3 soit particulièrement avantageuse et commode à utiliser puisqu'elle ne demande qutune simple traction sur la tringle 14 pour se déployer tandis que le réenroulement est spontané. It is obvious that the film can be wound in different ways, for example in a single roll around the movable rod 14, as shown in FIG. 4, although the embodiment of FIGS. 1 to 3 is particularly advantageous and convenient to use since it requires only a simple pull on the rod 14 to deploy while the rewinding is spontaneous.

Le film peut entre perforé de différentes façons de manière à assurer une certaine ventilation minimale, surtout lorsqu'il est utilisé pour fermer des conteneurs travaillant à des températuroe inférieures à 0 C tandis que, pour des conteneurs simplement réfrigérés, on utilise avantageusement un film non perforé. The film can be perforated in various ways so as to ensure a certain minimum ventilation, especially when it is used to close containers working at temperatures below 0 C while, for simply refrigerated containers, a film is advantageously not perforated.

D'autres variantes pourront être prévues pour adapter la bâche aux différents conteneurs en usage, aussi bien du type représenté que de n'importe quel autre type normalement en usage, vertical ou horizontal.  Other variants may be provided to adapt the cover to the various containers in use, both of the type shown and of any other type normally in use, vertical or horizontal.
