Description

Coque de conditionnement de fromages à aération ajustable
L'invention concerne les coques de conditionnement de fromage destinées à recevoir des fromages en vue de leur commercialisation, puis de la poursuite éventuelle de leur affinage chez le consommateur.Cheese packaging shell with adjustable ventilation
The invention relates to cheese packaging shells intended to receive cheeses with a view to their marketing, and then the possible further refining thereof at the consumer.

A 1'heure actuelle, les fromages provenant d'une cave de fabrication et de début d'affinage sont commercialisés, en particulier dans les grandes surfaces, soit en emballages étanches à la vapeur d'eau et/ou à l'air, soit en emballages perméables à la vapeur d'eau et à l'air, soit encore dans un emballage constitué par une coque percée de trous. At present, the cheeses from a manufacturing and early ripening cellar are sold, in particular in supermarkets, either in vapor-tight and / or air-tight packaging, or in packages permeable to water vapor and air, or even in a package consisting of a shell pierced with holes.

La coque percée présente des avantages. Elle protège le fromage du milieu extérieur tout en permettant des échanges gazeux avec l'extérieur. Les emballages étanches permettent de leur côté d'éviter le séchage du fromage, en maintenant autour du fromage une humidité créée par l'évaporation d'une partie de 1'eau contenue dans le fromage. The pierced shell has advantages. It protects the cheese from the outside environment while allowing gas exchanges with the outside. The sealed packages, for their part, prevent drying of the cheese, while maintaining around the cheese a humidity created by the evaporation of part of the water contained in the cheese.

Aucune de ces solutions n'est pourtant pleinement satisfaisante. None of these solutions is however fully satisfactory.

Un emballage étanche s'oppose à la respiration du fromage en cours d'affinage. Or des échanges gazeux en oxygène et CO2 sont nécessaires pour permettre la poursuite de l'affinage : par exemple les besoins d'échange en oxygène et CO peuvent dépasser un m3 par m de fromage et par 24 heures pour des fromages à croûte lavée. A sealed package prevents the breathing of cheese during ripening. However, gas and oxygen and CO2 exchanges are necessary to allow further refining: for example, the oxygen and CO exchange needs can exceed one m3 per m of cheese and per 24 hours for washed rind cheeses.

Les coques perforées provoquent un dessèchement important qui nuit aux qualités organoleptiques du fromage lorsque ce dernier est conservé dans une ambiance très sèche. The perforated shells cause significant drying which harms the organoleptic qualities of the cheese when the latter is stored in a very dry environment.

La présente invention vise à fournir une coque de conditionnement de fromage permettant tout à la fois de protéger le fromage du milieu extérieur, d'éviter le contact direct des surfaces latérale et supérieure du fromage avec les parois de la coque et d'ajuster les échanges gazeux avec l'extérieur. The present invention aims to provide a cheese packaging shell allowing both to protect the cheese from the outside environment, to avoid direct contact of the side and top surfaces of the cheese with the walls of the shell and to adjust the exchanges gaseous with the outside.

Dans ce but, l'invention propose notamment une coque de conditionnement de fromages comprenant une base de réception du fromage, avantageusement de forme telle que le fromage puisse tre découpé sur la base, et un couvercle encliquetable sur la base dans une position de fermeture et définissant, autour du fromage, un volume de circulation d'air, ledit couvercle étant déplaçable en translation ou en rotation sur la base entre une première position où des ouies de communication ménagées dans le couvercle sont fermées et une seconde position où les ouies sont ouvertes, les ouies étant régulièrement réparties angulairement et le couvercle restant retenu sur la base dans les deux positions. For this purpose, the invention proposes in particular a cheese packaging shell comprising a base for receiving the cheese, advantageously of a shape such that the cheese can be cut out on the base, and a snap-on cover on the base in a closed position and defining, around the cheese, an air circulation volume, said cover being displaceable in translation or in rotation on the base between a first position where communication openings formed in the cover are closed and a second position where the openings are open , the openings being regularly distributed angularly and the cover remaining retained on the base in the two positions.

Ces deux positions sont avantageusement matérialisées par des butées. These two positions are advantageously embodied by stops.

Une telle coque permet de contrôler les communications entre le volume intérieur de la coque et l'atmosphère. Such a shell makes it possible to control the communications between the interior volume of the shell and the atmosphere.

Lorsque la coque est dans une pièce d'habitation, par exemple dans une cuisine, le couvercle peut tre placé de façon à ouvrir les ouies, au moins partiellement, de façon à compléter l'affinage du fromage, dont on sait qu'il doit correspondre à une perte d'eau de 3 à 5% en 35 jours dans la plupart des cas. Lorsque la coque est mise au réfrigérateur, les ouies sont préalablement fermées. Ainsi on évite tout à la fois la diffusion des odeurs dans le réfrigérateur et le dessèchement du fromage, dont l'affinage n'évolue pas à la basse température qui règne dans un réfrigérateur.When the shell is in a living room, for example in a kitchen, the cover can be placed so as to open the gills, at least partially, so as to complete the ripening of the cheese, which we know must be correspond to a loss of water of 3 to 5% in 35 days in most cases. When the shell is put in the refrigerator, the gills are previously closed. This avoids both the diffusion of odors in the refrigerator and the drying out of the cheese, the ripening of which does not change at the low temperature prevailing in a refrigerator.

Les ouies peuvent tre délimitées par des moyens très divers, tels qu'un diaphragme réglable, des ouvertures du couvercle occultés pour une position déterminée du couvercle sur la base en translation ou en rotation, des trous dans lesquels s'enfoncent des bouchons coniques, des volets coulissants ou déformables, etc. The openings can be delimited by very diverse means, such as an adjustable diaphragm, openings of the cover concealed for a determined position of the cover on the base in translation or in rotation, holes in which conical plugs are inserted, sliding or deformable shutters, etc.

La forme de la coque et la dimension des ouies sont choisies en fonction de la nature du fromage que doit recevoir la coque. En particulier on utilisera généralement des formes beaucoup plus profondes pour les fromages de grande hauteur, tels que de nombreux fromages de chèvre. On utilisera, au contraire, une forme beaucoup plus plate dans le cas de fromages ronds, tels que les camemberts, l'époisses, etc. The shape of the shell and the size of the gills are chosen according to the nature of the cheese that the shell must receive. In particular, much deeper shapes will generally be used for tall cheeses, such as many goat cheeses. On the contrary, a much flatter shape will be used in the case of round cheeses, such as camembert, époisses, etc.

Les caractéristiques ci-dessus ainsi que d'autres apparaîtront mieux à la lecture de la description qui suit de modes particuliers d'exécution, donnés à titre d'exemple non limitatif. La description se réfère aux dessins qui l'accompagnent dans lesquels :
-La figure 1 est une vue en perspective d'un premier mode de réalisation, montrant le couvercle dans une orientation telle que les ouies sont fermées,
-la figure 2 est une vue éclatée, montrant la base séparée du couvercle,
-la figure 3 est une vue de détail, en coupe suivant un plan passant par l'axe de la coque,
-la figure 4 est une vue en perspective montrant un autre mode de réalisation, le couvercle étant dans une orientation telle que les ouies soient ouvertes,
-les figures 5A et 5B sont des vues en coupe partielle de la figure 4, suivant un plan V-V passant par un des volets de la cloche, placée en positions ouverte (fig. 5A) et fermée (fig. 5B).The above characteristics as well as others will appear better on reading the following description of particular embodiments, given by way of nonlimiting example. The description refers to the accompanying drawings in which:
FIG. 1 is a perspective view of a first embodiment, showing the cover in an orientation such that the gills are closed,
FIG. 2 is an exploded view showing the base separated from the cover,
FIG. 3 is a detail view, in section on a plane passing through the axis of the shell,
FIG. 4 is a perspective view showing another embodiment, the cover being in an orientation such that the openings are open,
FIGS. 5A and 5B are views in partial section of FIG. 4, along a plane VV passing through one of the flaps of the bell, placed in the open (fig. 5A) and closed (fig. 5B) positions.

-les figures 6 et 7 sont respectivement des vues de dessus de la coque complète de la figure 4 et de sa base. FIGS. 6 and 7 are respectively top views of the complete shell of FIG. 4 and its base.

La coque montrée sur les figures 1 à 3 peut tre considérée comme constituée d'une base 10 formant un plateau support et d'un couvercle 12 en forme de cloche à fond plat. Une telle coque est notamment utilisable pour recevoir des fromages se présentant sous forme plate et ronde, tels que camembert et surtout époisses. Ces deux composants peuvent tre en polypropylène thermo-formé.  The shell shown in FIGS. 1 to 3 can be considered to consist of a base 10 forming a support plate and a cover 12 in the form of a bell with a flat bottom. Such a shell is especially usable for receiving cheeses in flat and round form, such as camembert and especially époisses. These two components can be made of thermoformed polypropylene.

La base 10 présente une zone centrale plate ou munie de nervures, destinée à recevoir le fromage 14 (fig. 3), et un rebord externe 16 présentant une saillie circonférentielle interne 18 dont le rôle apparaîtra plus loin. The base 10 has a flat central zone or provided with ribs, intended to receive the cheese 14 (FIG. 3), and an external rim 16 having an internal circumferential projection 18 whose role will appear later.

Entre la zone plate et le rebord sont ménagées successivement dans le mode de réalisation illustré, une rainure circonférentielle optionnelle destinée à recevoir une bande enveloppant le fromage 20 et trois bossages 22 régulièrement répartis angulairement (ce nombre n'étant pas limitatif). Between the flat area and the rim are formed successively in the illustrated embodiment, an optional circumferential groove intended to receive a strip enveloping the cheese 20 and three bosses 22 regularly distributed angularly (this number not being limiting).

Le couvercle 12 comporte, à partir du fond, une paroi tronconique 24 et une portion annulaire à section en forme de L destinée à s'encliqueter dans le rebord externe 16. The cover 12 comprises, from the bottom, a frustoconical wall 24 and an annular portion of L-shaped section intended to snap into the outer rim 16.

Une fois le couvercle en place, il est retenu élastiquement par la saillie 18, mais peut tre enlevé par traction.Once the cover is in place, it is retained elastically by the projection 18, but can be removed by traction.

Dans le couvercle sont ménagées trois ouvertures d'aération 26 dont l'emplacement est tel qu'elles soient obturées par les bossages 22 de la base lorsque leur position angulaire coincide avec celle des bossages. Des renflements 28 du couvercle situés d'un seul côté de chaque ouverture livrent passage aux bossages lorsqu'on fait tourner le couvercle. Ils permettent d'amener ce dernier dans une position de butée définie par la longueur des renflements et choisie pour que les ouvertures débouchent. In the cover are provided three ventilation openings 26 whose location is such that they are closed by the bosses 22 of the base when their angular position coincides with that of the bosses. Bulges 28 of the cover located on one side of each opening allow passage to the bosses when the cover is rotated. They allow the latter to be brought into a stop position defined by the length of the bulges and chosen so that the openings open.

On voit que les ouvertures constituent des ouies d'aération que l'on peut à volonté fermer ou ouvrir sans avoir à enlever et remettre le couvercle, simplement en faisant tourner ce dernier entre deux positions de butée. It can be seen that the openings constitute ventilation openings which can be closed or opened at will without having to remove and replace the cover, simply by rotating the latter between two stop positions.

Le fromage est maintenu écarté des parois, ce qui permet une aération homogène.The cheese is kept away from the walls, allowing uniform ventilation.

La coque montrée en figures 4 à 7 présente encore une base 10a et un couvercle 12a, mais ce dernier est beaucoup plus profond que dans le cas précédent, de façon à recevoir des fromages ayant un rapport hauteur/diamètre important, tels que des fromages de chèvre. Pour permettre une circulation tout le long du fromage, des ouvertures sont ménagées sur toute la hauteur de la cloche. The shell shown in Figures 4 to 7 still has a base 10a and a cover 12a, but the latter is much deeper than in the previous case, so as to receive cheeses having a high height / diameter ratio, such as cheeses of goat. To allow circulation throughout the cheese, openings are provided over the entire height of the bell.

La base présente encore une forme de plateau avec une zone centrale d'appui de fromage 14a et un rebord interne cylindrique 16a d'encliquetage du couvercle. La zone centrale peut tre plate, comme indiqué sur les figures, ou munie de cannelures en arcs de cercle ou radiales permettant de collecter les exsudats. Entre la zone centrale et le rebord est ménagée une rigole à section en V dont le fond anguleux présente un rayon variable sur le pourtour, de façon à constituer quatre cames 32 (ce nombre n'étant pas limitatif) régulièrement réparties angulairement). The base also has a tray shape with a central area for supporting cheese 14a and a cylindrical internal rim 16a for snap-fastening the cover. The central zone can be flat, as indicated in the figures, or provided with grooves in arcs of a circle or radials making it possible to collect the exudates. Between the central zone and the rim is formed a V-shaped channel whose angular bottom has a variable radius on the periphery, so as to constitute four cams 32 (this number not being limiting) regularly distributed angularly).

Comme le montrent les figures 5A, 5B et 6 la rigole est définie à sa base par une arte interne circulaire 40 et par une arte, externe dans le sens radial, 42 de forme ondulée. As shown in FIGS. 5A, 5B and 6, the channel is defined at its base by a circular internal edge 40 and by an edge, external in the radial direction, 42 of wavy shape.

Le couvercle 12a est en forme de cloche à fond plat et à paroi latérale tronconique. Cette paroi se prolonge par une collerette annulaire plate 34 et une portion de révolution 36 à section en L, destinée à s'encliqueter dans le rebord externe 16a en laissant le couvercle libre de tourner. The cover 12a is in the form of a bell with a flat bottom and a frustoconical side wall. This wall is extended by a flat annular flange 34 and a portion of revolution 36 with an L-shaped section, intended to snap into the outer rim 16a while leaving the cover free to rotate.

Dans la paroi tronconique et la collerette annulaire 34 sont découpés quatre volets 38 qui restent attachés au fond du couvercle. La fraction du volet découpée dans la collerette 34 est mise en forme pour tre dans le prolongement du reste du volet. Elle traverse la brèche pratiquée dans la collerette et est emprisonnée dans la rigole lorsque le couvercle est enfoncé. Elle est soumise à la pression des cames lorsque l'on fait tourner le couvercle. In the frustoconical wall and the annular flange 34 are cut four flaps 38 which remain attached to the bottom of the cover. The fraction of the shutter cut from the flange 34 is shaped so as to be an extension of the rest of the shutter. It crosses the breach made in the collar and is trapped in the channel when the cover is pressed. It is subjected to pressure from the cams when the cover is rotated.

Lorsque le couvercle est dans l'orientation montrée en figures 4 et 5A, l'arte inférieure de chaque volet 38 est repoussée radialement vers l'extérieur par une came et libère deux ouies de passage d'air. Lorsqu'au contraire le couvercle est dans la position montrée en figure 5B, les volets 38 sont ramenés dans la continuité de la paroi latérale et les ouies sont pratiquement closes. When the cover is in the orientation shown in FIGS. 4 and 5A, the lower edge of each flap 38 is pushed radially outwards by a cam and releases two air passage openings. When, on the contrary, the cover is in the position shown in FIG. 5B, the flaps 38 are brought back into the continuity of the side wall and the gills are practically closed.

Les orientations de pleine ouverture et de fermeture des ouies peuvent tre matérialisées par des butées. Pour maintenir le couvercle dans la position angulaire où il est amené manuellement, un crantage de retenue élastique peut tre prévu sur une zone cylindrique 44 reliant la zone centrale à la rigole. The full opening and closing orientations of the louvers can be materialized by stops. To maintain the cover in the angular position where it is brought manually, an elastic retaining notch can be provided on a cylindrical zone 44 connecting the central zone to the channel.

Pour permettre 1'empilage de plusieurs coques, le diamètre de la zone cylindrique en retrait peut correspondre à celui du fond et des saillies internes de la zone cylindrique peuvent tre prévues pour limiter 1'enfoncement du couvercle. Des nervures internes du couvercle s'étendant sur une fraction de la hauteur à partir du fond, peuvent tre prévues pour caler le fromage 14a à l'intérieur et garantir le maintien d'un espace annulaire d'aération tout autour.  To allow stacking of several shells, the diameter of the recessed cylindrical zone can correspond to that of the bottom and internal projections of the cylindrical zone can be provided to limit the depression of the cover. Internal ribs of the cover extending over a fraction of the height from the bottom can be provided to wedge the cheese 14a inside and guarantee the maintenance of an annular ventilation space all around.
