Description

L'invention est relative à une boîte d'emballage, spécialement adaptée au conditionnement de produits alimentaires tels que produits de boulangerie, de pâtisserie ou similaires.The invention relates to a packaging box, specially adapted for packaging food products such as bakery, pastry products or the like.

Traditionnellement, pour le conditionnement des gâteaux, tartes, pâtisseries ou similaires, dans le domaine commercial, la boîte préfabriquée en feuille cartonnée est utilisée. Il s'agit d'une boîte découpée dans une fine feuille cartonnée qui est repliée et que le pâtissier déploie dans son magasin pour y placer les gâteaux choisis par les clients.Traditionally, for the packaging of cakes, pies, pastries or the like, in the commercial field, the prefabricated cardboard box is used. It is a box cut from a thin cardboard sheet which is folded and which the pastry chef deploys in his store to place the cakes chosen by customers.

Ce mode de conditionnement offre l'avantage d'être économique et d'occuper peu de place lorsque la boîte est préalablement repliée. Cependant on peut lui reprocher certains inconvénients car il s'agit généralement d'une boîte très peu ridige et au-delà d'une certaine dimension, des précautions importantes doivent être prises pour pallier ces fléchissements. Par ailleurs la boîte n'est pas étanche et craint l'humidité. De ce fait, on ne peut stocker longtemps les produits dans ce type de boîte.This packaging method offers the advantage of being economical and occupying little space when the box is folded beforehand. However, it can be criticized for certain drawbacks because it is generally a box that is very unobtrusive and beyond a certain dimension, important precautions must be taken to compensate for these deflections. In addition, the box is not waterproof and fears humidity. As a result, products cannot be stored for a long time in this type of box.

Un autre reproche que l'on peut formuler est la difficulté, par exemple dans le cas d'une tarte, de récupérer le gâteau de la boîte pour le mettre sur un plat. Cette opération de transvasement est toujours délicate car la boîte n'est pas rigide et les bords forment un obstacle pour glisser le gâteau hors de la boîte.Another criticism that can be made is the difficulty, for example in the case of a pie, of recovering the cake from the box to put it on a dish. This transfer operation is always delicate because the box is not rigid and the edges form an obstacle to slide the cake out of the box.

Dans le cas des pâtisseries industrielles, de telles boîtes de carton sont complètement inutilisables. En effet, il est indispensable de présenter la marchandise à la vue du consommateur pour attirer son attention et pour qu'il puisse faire un choix. A cet égard, la première solution, qui a été adoptée, a été la mise en place d'une fenêtre transparente sur les emballages cartonnés.In the case of industrial pastries, such cardboard boxes are completely unusable. Indeed, it is essential to present the goods to the view of the consumer to attract his attention and so that he can make a choice. In this regard, the first solution, which was adopted, was the installation of a transparent window on the cardboard packaging.

Ceci n'est guère satisfaisant car, d'une part, la mise en place d'une fenêtre transparente sur un emballage cartonné en augmente très sensiblement le coût et d'autre part, la vision offerte du gâteau n'est pas excellente. Il faut également souligner que la pâtisserie industrielle est susceptible d'être stockée relativement longtemps dans les magasins en armoire réfrigérée.This is hardly satisfactory because, on the one hand, the installation of a transparent window on a cardboard packaging very significantly increases the cost and, on the other hand, the vision offered of the cake is not excellent. It should also be noted that industrial baking is likely to be stored relatively long in stores in a refrigerated cabinet.

Un tel stockage en armoire réfrigérée rend impossible l'utilisation des boîtes traditionelles carton car ce dernier craint l'humidité. En outre, lors du stockage, les boîtes sont gerbées les unes sur les autres et le manque de rigidité de telles boîtes carton rend risqué voire même impossible le gerbage.Such storage in a refrigerated cabinet makes it impossible to use traditional cardboard boxes because the latter fears humidity. In addition, during storage, the boxes are stacked on top of each other and the lack of rigidity of such cardboard boxes makes stacking risky or even impossible.

C'est pourquoi est apparu sur le marché une nouveau type de conditionnement qui se présente sous la forme d'un emballage en matière plastique totalement transparent, formé d'une double coque séparée par une arête de pliage, telle que l'on puisse placer deux coques en vis-à-vis et enfermer la marchandise à l'intérieur de celle-ci. Cet emballage est généralement obtenu par thermoformage et offre une vision totale du produit. En outre, il ne craint pas l'humidité et sa rigidité, quoique quelquefois faible, est supérieure à celle des boîtes en carton.This is why a new type of packaging has appeared on the market, which is in the form of a completely transparent plastic packaging, formed by a double shell separated by a folding edge, such that one can place two hulls facing each other and enclose the goods inside thereof. This packaging is generally obtained by thermoforming and offers a total vision of the product. In addition, it does not fear humidity and its rigidity, although sometimes weak, is greater than that of cardboard boxes.

Ce type de conditionnement a eu un développement important dans les grandes surfaces de vente où la marchandise est stockée dans des bacs linéaires, notamment réfrigérés pour assurer une meilleure conservation des produits stockés.This type of packaging has had a significant development in large sales areas where the goods are stored in linear bins, especially refrigerated to ensure better conservation of the products stored.

Cependant, il s'avère qu'un tel emballage transparent ne donne pas entière satisfaction sur le plan de l'emballage et sur le plan de la présentation.However, it turns out that such transparent packaging is not entirely satisfactory in terms of packaging and in terms of presentation.

Tout d'abord, en ce qui concerne le gerbage de tels emballages, il n'existe aucun dispositif de positionnement qui permet d'assurer un bon équilibre à la pile et dans ces conditions, tout empilage est précaire. Cependant, il ne s'agit peut-être pas du plus grand défaut de ces boîtes car l'utilisateur peut pallier cet inconvénient en limitant la hauteur des piles.First of all, as regards the stacking of such packages, there is no positioning device which makes it possible to ensure good balance in the stack and under these conditions, any stacking is precarious. However, this is perhaps not the greatest defect of these boxes because the user can overcome this drawback by limiting the height of the stacks.

Cependant, le plus grand défaut rencontré se situe au niveau des phénomènes de condensation liés à une fabrication effectuée sur le site. En effet, de plus en plus fréquemment, les grandes surfaces de vente sont équipées pour fabriquer elles-mêmes leur pâtisserie, et pour des raisons de cadence, de place de stockage ou autre, les pâtissiers conditionnent leurs produits dès qu'ils sortent du four. Les tartes sont donc placées dans des emballages de type à deux coques, et tout aussitôt, elles sont dirigées dans des bacs réfrigérés pour être offertes à la vente.However, the biggest defect encountered is at the level of condensation phenomena linked to a manufacturing carried out on the site. Indeed, more and more frequently, large sales areas are equipped to make their own pastry, and for reasons of cadence, storage space or other, pastry chefs condition their products as soon as they come out of the oven. The pies are therefore placed in packages of the type with two shells, and immediately they are sent to refrigerated containers to be offered for sale.

La rapidité d'exécution de ces opérations fait qu'il y a une brutale transition entre le four et le bac réfrigéré où la température n'avoisine que quelques degrés Celsius. Cette différence de température produit des phénomènes de condensation sur la paroi intérieure de coques, ce qui détruit l'image du produit.The speed of execution of these operations means that there is a brutal transition between the oven and the refrigerated tray where the temperature is only a few degrees Celsius. This temperature difference produces condensation phenomena on the inner wall of shells, which destroys the image of the product.

De plus, le manque d'aération, tant interne qu'externe, de telles boîtes d'emballage fait que l'eau condensée est très longue à s'éliminer, et dans certains cas, peut entraîner des phénomènes de moisissures. Dans le cas des boîtes d'emballage à coques connues, ce défaut de condensation est encore augmenté si l'on empile les boîtes car les deux coques sont appliquées l'une contre l'autre et interdisent toute circulation d'air interne et externe.In addition, the lack of ventilation, both internal and external, of such packaging boxes means that the condensed water takes a very long time to be eliminated, and in certain cases, can cause mold phenomena. In the case of packaging boxes with known shells, this condensation defect is further increased if the boxes are stacked because the two shells are applied against each other and prevent any circulation of internal and external air.

Le but principal de la présente invention est de présenter une boîte d'emballage, spécialement adaptée au conditionnement de produits alimentaires, tels que produits de boulangerie, de pâtisserie ou similaire, conçue pour résoudre les problèmes généralement rencontrés lors de la fabrication de tels produits alimentaires en grande surface, et également pour faciliter et rendre plus commode l'emploi de ces boîtes d'emballage.The main object of the present invention is to present a packaging box, specially adapted for the packaging of food products, such as bakery, pastry products or the like, designed to solve the problems generally encountered during the manufacture of such food products. in large areas, and also to facilitate and make more convenient the use of these packaging boxes.

Tout d'abord, la boîte d'emballage de la présente invention a été spécialement étudiée pour résoudre les phénomènes de condensation rencontrés notamment lors de la mise en place rapide des produits alimentaires tels que pâtisserie ou similaire, en bac linéaire réfrigéré à la sortie du four.First of all, the packaging box of the present invention has been specially studied to solve the condensation phenomena encountered in particular during the rapid placement of food products such as pastry or the like, in a refrigerated linear container at the outlet of the oven.

Le choc thermique provoque inévitablement une condensation à l'intérieur de la boîte, mais selon la présente invention, la vapeur d'eau est très rapidement éliminée afin que n'apparaisse aucune condensation au niveau des parois internes de la boîte.The thermal shock inevitably causes condensation inside the box, but according to the present invention, the water vapor is very quickly eliminated so that no condensation appears at the internal walls of the box.

En outre, la boîte de la présente invention a été particulièrement étudiée pour être gerbée et autoriser un empilage stable même si le support de base est sensiblement incliné, ce qui est généralement le cas.In addition, the box of the present invention has been particularly designed to be stacked and allow a stable stacking even if the base support is significantly inclined, which is generally the case.

Il est à noter également que, selon la présente invention, on obtient une circulation d'air entre les produits et à l'intérieur des boîtes, même lorsque le bac réfrigéré est totalement rempli de boîtes d'emballage empilées.It should also be noted that, according to the present invention, an air circulation is obtained between the products and inside the boxes, even when the refrigerated container is completely filled with stacked packaging boxes.

Par ailleurs, sur le plan de la commodité, grâce à la présente invention, il n'y a plus à effectuer de transvasement entre la boîte d'emballage et un plat. En effet, la boîte d'emballage de la présente invention constitue par sa partie inférieure un plat qui peut éventuellement être utilisé directement pour servir le produit alimentaire ainsi conditionné.Furthermore, in terms of convenience, thanks to the present invention, there is no longer any need to transfer between the packaging box and a dish. In fact, the packaging box of the present invention constitutes, by its lower part, a dish which can possibly be used directly to serve the food product thus conditioned.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.

Selon l'invention, la boîte d'emballage, spécialement adaptée au conditionnement de produits alimentaires, tels que produits de boulangerie, de pâtisserie ou similaires, constituée d'un plateau sur lequel ledit produit est déposé ainsi que d'un couvercle protecteur emboîtable sur le plateau, est caractérisée par le fait qu'elle présente des moyens pour créer une circulation d'air à l'intérieur de la boîte, afin d'éviter les phénomènes de condensation au niveau des parois internes de la boîte.According to the invention, the packaging box, specially adapted for the packaging of food products, such as bakery, pastry products or the like, consists of a tray on which said product is deposited as well as a protective cover which can be fitted onto the tray is characterized by the fact that it has means for creating an air circulation inside the box, in order to avoid condensation phenomena at the level of the internal walls of the box.

Selon un mode de réalisation de la présente invention, ces moyens se présentent sous la forme de canaux de circulation latéraux indéformables, même lors du gerbage des boîtes. En outre, la boîte d'emballage de l'invention présente des moyens pour autoriser le gerbage et/ou assurer une aération externe, en particulier une libre circulation d'air sous le plateau et sur le couvercle.According to an embodiment of the present invention, these means are in the form of non-deformable lateral circulation channels, even during stacking of the boxes. In addition, the packaging box of the invention has means for authorizing stacking and / or ensuring external ventilation, in particular a free circulation of air under the tray and on the cover.

La présente invention concerne une boîte d'emballage, spécialement adaptée au conditionnement de produits alimentaires tels que produits de boulangerie, de pâtisserie ou similaires.The present invention relates to a packaging box, specially adapted for packaging food products such as bakery, pastry products or the like.

Elle trouvera notamment son application dans le domaine commercial pour conditionner de tels produits, tels que par exemple des tartes, pâtisseries ou autres.It will in particular find its application in the commercial field for packaging such products, such as for example pies, pastries or others.

Les objectifs visés par la boîte d'emballage de la présente invention sont typiques à ce genre de conditionnement car il est nécessaire que l'emballage supporte l'ambiance de bacs réfrigérés, autorise le gerbage, et permette une présentation impeccable de la marchandise proposée à la vente.The objectives of the packaging box of the present invention are typical for this type of packaging because it is necessary that the packaging supports the atmosphere of refrigerated bins, allows stacking, and allows an impeccable presentation of the goods offered to the sale.

Aussi, il est nécessaire d'utiliser une boîte d'emballage au moins transparente sur une partie de la boîte et qui le reste malgré les conditions d'utilisation de la boîte, c'est-à-dire qui soit exempte de tout phénomène de condensation.Also, it is necessary to use a packaging box at least transparent on a part of the box and which remains so despite the conditions of use of the box, that is to say which is free from any phenomenon of condensation.

La boîte d'emballage, telle que notamment illus­trée à la figure 1, est formée de deux parties emboîtables, à savoir une embase inférieure (2) en forme de plateau où la marchandise est déposée ainsi qu'un couvercle protecteur (1) emboîtable sur ledit plateau.The packaging box, as illustrated in particular in FIG. 1, is formed of two nestable parts, namely a lower base (2) in the form of a tray where the goods are deposited as well as a protective cover (1) nestable on said tray.

Cette structure offre le premier avantage de pouvoir servir directement les produits alimentaires et notamment les pâtisseries à table, directement sur le plateau, sans qu'aucune opération de transvasement ne soit nécessaire. Il s'agit d'un aspect de commodité et en outre le plateau présente une bonne esthétique.This structure offers the first advantage of being able to serve food products directly and especially pastries at the table, directly on the tray, without any transfer operation being necessary. It is an aspect of convenience and in addition the tray has a good aesthetic.

En ce qui concerne le couvercle protecteur (1), il est de préférence confectionné dans une matière plastique transparente pour donner une vue du contenu de la boîte. Bien entendu, le format de la boîte d'emballage est à adapter selon les dimensions du produit à emballer.Regarding the protective cover (1), it is preferably made of a transparent plastic material to give a view of the contents of the box. Of course, the format of the packaging box is to be adapted according to the dimensions of the product to be packaged.

Avantageusement, le plateau et le couvercle sont confectionnés dans une matière plastique thermoformable, ce qui permettra à la boîte de supporter l'humidité et de la réaliser selon un procédé de fabrication économique.Advantageously, the tray and the cover are made of a thermoformable plastic material, which will allow the box to withstand the humidity and produce it according to an economical manufacturing process.

Selon la présente invention, la boîte d'emballage présente des moyens pour créer une circulation d'air à l'intérieur de la boîte, afin d'éviter les phénomènes de condensation au niveau des parois internes de la boîte.According to the present invention, the packaging box has means for creating an air circulation inside the box, in order to avoid condensation phenomena at the level of the internal walls of the box.

Selon un mode de réalisation de l'invention, tel qu'illustré en détails aux figures 5 et 7, lesdits moyens pour créer la circulation d'air à l'intérieur de la boîte se présentent sous la forme de canaux de circulation (10) latéraux indéformables lors du gerbage des boîtes.According to one embodiment of the invention, as illustrated in detail in FIGS. 5 and 7, said means for creating the circulation of air inside the box are in the form of circulation channels (10) non-deformable sides when stacking boxes.

Plus précisément, le plateau (2) comprend sur sa périphérie une série d'ouïes d'aération (7) qui coopèrent avec le couvercle pour former lesdits canaux de circulation.More specifically, the plate (2) comprises on its periphery a series of air vents (7) which cooperate with the cover to form said circulation channels.

Le plateau (2) comprend à sa périphérie un rebord (8) qui permet, d'une part, l'emboîtement du couvercle (1) et d'autre part, assure une certaine rigidité au plateau.The plate (2) comprises at its periphery a flange (8) which allows, on the one hand, the fitting of the cover (1) and on the other hand, provides a certain rigidity to the plate.

Sur ce rebord (8) on crée à intervalles une déformation (9), comme le montre particulièrement la figure 1, définissant entre la paroi du couvercle (1) et le rebord (8) lesdites ouïes d'aération (7) permettant une circulation de l'air telle que schématisée par les flèches (11) à la figure 5. Ces ouïes d'aération (7) sont réparties sur le pourtour du plateau (2) en fonction des dimensions des boîtes d'emballage pour créer une admission d'air suffisante et une circulation d'air suffisante pour éliminer les phénomènes de condensation.On this rim (8) a deformation (9) is created at intervals, as shown particularly in FIG. 1, defining between the wall of the cover (1) and the rim (8) said ventilation openings (7) allowing circulation air as shown diagrammatically by the arrows (11) in FIG. 5. These ventilation openings (7) are distributed around the periphery of the tray (2) according to the dimensions of the packaging boxes to create an inlet for sufficient air and sufficient air circulation to eliminate condensation phenomena.

Cela étant, le plateau (2) comporte un système de fixation du couvercle (1) pour, d'une part, éviter que ce dernier ne puisse se retirer accidentellement, et pour, d'autre part, maintenir l'ouverture des ouïes d'aération (7) lors du gerbage des boîtes.However, the tray (2) has a cover fixing system (1) to, on the one hand, prevent this the latter cannot be removed accidentally, and for, on the other hand, maintaining the opening of the ventilation openings (7) when stacking the boxes.

Dans l'exemple choisi, tel que représenté à la figure 2, le plateau comporte des clips latéraux (12) qui se présentent sous la forme d'une excroissance extérieure du rebord (8). Ces clips (12) coopèrent avec une gorge périphérique (13), réalisée sur le pourtour du couvercle (1), comme le montre particulièrement la figure 6.In the example chosen, as shown in FIG. 2, the plate comprises lateral clips (12) which are in the form of an external projection of the flange (8). These clips (12) cooperate with a peripheral groove (13), produced on the periphery of the cover (1), as particularly shown in FIG. 6.

L'emboîtement des clips (12) dans la gorge (13), autorisé par la déformation relative des matériaux, provoque le verrouillage du couvercle (1) sur le plateau.The fitting of the clips (12) into the groove (13), authorized by the relative deformation of the materials, causes the locking of the cover (1) on the plate.

Pour faciliter l'extraction du couvercle, avanta­geusement on dote ce dernier de languettes (14), et de même, le plateau (2) sera avantageusement doté de languettes (15).To facilitate the extraction of the cover, advantageously the latter is provided with tongues (14), and likewise, the plate (2) will advantageously be provided with tongues (15).

Lesdites languettes (14, 15) faciliteront d'une part la préhension de la boîte et d'autre part permettront la séparation du plateau et du couvercle par le consommateur.Said tabs (14, 15) will facilitate on the one hand the gripping of the box and on the other hand allow the separation of the tray and the cover by the consumer.

En outre, selon une autre caractéristique de l'invention, la boîte d'emballage présente des moyens pour autoriser le gerbage et/ou assurer une aération externe, autour de la boîte, en particulier une libre circulation d'air sous le plateau (2) et sur le couvercle (1).In addition, according to another characteristic of the invention, the packaging box has means for authorizing stacking and / or ensuring external ventilation around the box, in particular a free circulation of air under the tray (2 ) and on the cover (1).

Ainsi, selon la présente invention, l'air peut parfaitement circuler entre les produits, et à l'intérieur du conditionnement, afin que la réfrigération se fasse dans d'excellentes conditions.Thus, according to the present invention, the air can circulate perfectly between the products, and inside the packaging, so that the refrigeration is done in excellent conditions.

Autrement dit, lorsque le bac linéaire réfrigéré est fortement chargé, l'air peut circuler entre les boîtes à gâteaux pour évacuer rapidement la vapeur d'eau.In other words, when the refrigerated linear tray is heavily loaded, air can circulate between the cake boxes to quickly evacuate the water vapor.

A ce sujet, il existe deux types d'armoires réfrigérées, les armoires dites à froid statique, dans lesquelles la chaleur est évacuée uniquement par conduction et les armoires dites à froid pulsé.In this regard, there are two types of refrigerated cabinets, the so-called static cold cabinets, in which the heat is evacuated only by conduction and the so-called pulsed cold cabinets.

Ces dernières sont de plus en plus préférées car elles autorisent une capacité plus importante que les armoires à froid statique dont la capacité est faible car liée à la conduction thermique des produits entreposés.The latter are more and more preferred because they allow a higher capacity than static cold cabinets whose capacity is low because linked to the thermal conduction of the stored products.

En outre, dans le cas des armoires à froid pulsé, une circulation d'air forcée est entretenue dans le bac pour refroidir les produits entreposés. Cette technique est plus efficace et plus rapide car l'air circule librement entre les produits pour assurer une bonne répartition du froid.In addition, in the case of pulsed cold cabinets, forced air circulation is maintained in the tank to cool the stored products. This technique is more efficient and faster because air circulates freely between the products to ensure good distribution of the cold.

La structure de la présente invention ne constitue pas un obstacle à cette circulation d'air. En outre, cet air froid pulsé permet d'éliminer la vapeur d'eau.The structure of the present invention does not constitute an obstacle to this air circulation. In addition, this cold pulsed air eliminates water vapor.

La présente invention propose un mode de réalisation dont la structure constitue d'une part les moyens pour autoriser le gerbage et d'autre part pour autoriser l'aération externe.The present invention proposes an embodiment, the structure of which constitutes on the one hand the means for authorizing stacking and on the other hand for authorizing external ventilation.

Cesdits moyens se présentent sous la forme de pieds (3) disposés sous la surface (4) du plateau (2), comme le montrent particulièrement les figures 2 et 3. Ces pieds (3) sont créés par déformation du plateau (2) afin que sa surface (4) soit surélevée.These said means are in the form of feet (3) arranged under the surface (4) of the plate (2), as particularly shown in Figures 2 and 3. These feet (3) are created by deformation of the plate (2) so its surface (4) is raised.

Une forme avantageuse adoptée pour la boîte d'emballage de l'invention est circulaire car elle correspond notamment à la forme traditionnelle des tartes ou pâtisseries ou similaires. Cependant, d'autres formes géométriques pourraient parfaitement être adoptées.An advantageous shape adopted for the packaging box of the invention is circular because it corresponds in particular to the traditional shape of pies or pastries or the like. However, other geometric shapes could perfectly be adopted.

Dans ce cas, les pieds (3) sont disposés en cercle tels qu'illustrés à la figure 3, montrant le plateau (2) vu de dessous. Ces pieds se présentent sous la forme de plots discontinus équidistants du centre du plateau. La réalisation discontinue des pieds (3) permet d'assurer le passage de l'air sous la surface (4) du plateau (2).In this case, the feet (3) are arranged in a circle as illustrated in FIG. 3, showing the plate (2) seen from below. These feet are in the form of discontinuous studs equidistant from the center of the plate. The discontinuous production of the feet (3) ensures the passage of air under the surface (4) of the plate (2).

Par ailleurs, pour rigidifier le plateau dans sa partie centrale, et notamment pour éviter que la surface (4) du plateau ne se déforme par le poids du produit conditionné ou lorsqu'on le coupe, le plateau comporte dans sa partie centrale une nervure (5) circulaire.Furthermore, to stiffen the tray in its central part, and in particular to prevent the surface (4) of the tray from being deformed by the weight of the packaged product or when it is cut, the tray has in its central part a rib ( 5) circular.

Cela étant, pour autoriser le gerbage, lesdits pieds (3) coopèrent avec un profil complémentaire (6) formé sur le couvercle (1) pour aligner les boîtes lors d'un empilage et les positionner les unes par rapport aux autres, comme le montre par exemple la figure 4.However, to allow stacking, said feet (3) cooperate with a complementary profile (6) formed on the cover (1) to align the boxes during stacking and position them relative to each other, as shown for example Figure 4.

Il est en effet fréquent de devoir gerber les boîtes à gâteaux lors d'un remplissage de bac réfrigéré ou pour assurer leur transport. Pour favoriser une bonne tenue de l'empilage, il est préférable que ces boîtes d'emballage ne puissent pas glisser les unes par rapport aux autres.It is indeed common to have to stack the cake boxes when filling a refrigerated tray or to ensure their transport. To promote good holding of the stack, it is preferable that these packaging boxes cannot slide relative to one another.

C'est pourquoi lesdits moyens (3 et 6) coopèrent non seulement pour permettre une libre circulation de l'air sous la surface (4) du plateau (2) mais également pour autoriser un emboîtement du plateau (2) sur le couvercle (1) de la boîte de conditionnement inférieure. Cette dernière caractéristique assure une bonne stabilité de l'empilage.This is why said means (3 and 6) cooperate not only to allow a free circulation of air under the surface (4) of the plate (2) but also to authorize an interlocking of the plate (2) on the cover (1 ) from the lower packaging box. This last characteristic ensures good stability of the stack.

Dans le cas où les pieds (3) sont disposés en cercle, le couvercle (1) présente à sa partie supérieure une forme creusée (6) de profil circulaire, dont la dimension correspond à celle du cercle formé par les pieds (3).In the case where the feet (3) are arranged in a circle, the cover (1) has at its upper part a hollow shape (6) of circular profile, the dimension of which corresponds to that of the circle formed by the feet (3).

Plus précisément, les pieds (3) sont disposés en cercle dont le diamètre est inférieur audit profil circulaire afin que ceux-ci reposent dans la forme (6) creusée du couvercle inférieur.More specifically, the feet (3) are arranged in a circle whose diameter is less than said circular profile so that they rest in the shape (6) hollowed out of the lower cover.

Ces formes sont complémentaires, toutefois une autre forme géométrique pourrait être utilisée pour créer un emboîtement.These shapes are complementary, however another geometric shape could be used to create an interlocking.

Pour autoriser la circulation d'air sous la surface (4) du plateau (2), on déterminera la hauteur des pieds (3) telle qu'elle soit supérieure à la profondeur de la forme creusée (6) sur le dessus du couvercle (1).To allow air circulation under the surface (4) of the tray (2), the height of the feet (3) will be determined such that it is greater than the depth of the hollowed out shape (6) on the top of the cover ( 1).

Les différentes dispositions structurelles de la boîte d'emballage qui vient d'être décrite permettent donc de respecter les différents objectifs fixés, à savoir gerbage du produit, ventilation entre les boîtes, circulation d'air à l'intérieur des boîtes pour éviter les phénomènes de condensation, bonne présentation, bonne résistance des boîtes et fabrication de ces dernières à un coût compatible avec des impératifs de vente.The different structural arrangements of the packaging box which has just been described therefore make it possible to meet the various objectives set, namely stacking of the product, ventilation between the boxes, air circulation inside the boxes to avoid phenomena. condensation, good presentation, good resistance of the boxes and their manufacture at a cost compatible with sales requirements.

Il est également à noter que les moyens pour créer la circulation d'air à l'intérieur de la boîte sont indéformables, quel que soit le gerbage. En effet, ces moyens sont définis à la périphérie du plateau entre la paroi latérale du couvercle et le plateau, et plus précisément le rebord (8), ce qui crée un canal de circulation (10) dont l'ouverture est toujours assurée même si de nombreuses boîtes sont empilées. Lesdits canaux sont insensibles à une éventuelle déformation provoquée par la semi rigidité des matériaux utilisés également. De plus, on retrouve l'aération interne quelle que soit la forme du produit conditionné et quel que soit son poids.It should also be noted that the means for creating the air circulation inside the box are non-deformable, whatever the stacking. Indeed, these means are defined at the periphery of the tray between the side wall of the cover and the tray, and more precisely the rim (8), which creates a circulation channel (10) whose opening is always ensured even if many boxes are stacked. Said channels are insensitive to any deformation caused by the semi-rigidity of the materials also used. In addition, there is internal ventilation regardless of the shape of the packaged product and regardless of its weight.
