Abstract

Food packaging box (1) having a dish part (2) with a border flange (6), around its opening, in the plane of the opening also has a cover (3, 4, 5) articulated about a hinge (4) arrangement formed in one side of the cover (3) and with a heel zone (5) for fixing, partic. by ultrasonic welding, the cover to the dish border, and a rib (12) on the opposite side of the cover that keeps it in the closed position by engaging with the dish border. The area of the heel (5) is made of synthetic material e.g. PVC, compatible with that of the border of the dish part which itself may consist of two different synthetic materials, e.g. PE inside on contact with the food and PVC externally. Also claimed are prodn. processes for fixing the cover to the dish.

Description

L'objet de la présente invention est une boîte destinée au conditionnement, un procédé pour fabriquer une telle boîte, ainsi qu'un dispositif pour la mise en oeuvre de ce procédé. The object of the present invention is a box for packaging, a method for manufacturing such a box, as well as a device for the implementation of this process.

Dans l'industrie alimentaire, il est connu d'utiliser des boîtes pour le conditionnement de produits frais, notamment des boîtes du type comportant une barquette servant de contenant et munie d'une ouverture, ainsi qu'un rebord périphérique disposé dans le plan de l'ouverture autour de celle-ci. Une fois qu'une telle barquette est remplie, un opercule constitué par un film en matière synthétique vient recouvrir la barquette et est soudé sur le rebord de celle-ci. In the food industry, it is known to use boxes for packaging fresh products, in particular boxes of the type comprising a tray serving as container and provided with an opening, as well as a peripheral rim arranged in the plane of the opening around it. Once such a container is filled, a cover formed by a film of synthetic material covers the container and is welded to the rim thereof.

En général, le film fermant la barquette porte des indications, telles la marque du produit contenu dans la barquette, la date limite de consommation de ce produit et éventuellement le prix et d'autres indications sur ce produit (composition, label de qualité, etc). In general, the film closing the tray carries indications, such as the brand of the product contained in the tray, the expiration date of this product and possibly the price and other indications on this product (composition, quality label, etc. ).

Lorsqu'un consommateur ouvre la barquette, il retire l'opercule fermant son ouverture et le jette. S'il ne consomme pas tout le produit contenu dans la barquette en une seule fois, il replace le reste de ce produit dans la barquette, sans pouvoir refermer celle-ci. II ne possède donc plus les informations portées par l'opercule. De plus, le produit entamé n'est plus protégé et des odeurs peuvent se répandre. When a consumer opens the tray, he removes the seal closing its opening and discards it. If he does not consume all the product contained in the tray at once, he replaces the rest of this product in the tray, without being able to close it. He therefore no longer has the information carried by the seal. In addition, the product started is no longer protected and odors may spread.

Le but de l'invention est alors, en partant d'une barquette équipée ou non d'un opercule, de fournir une boîte permettant de mieux conserver le produit entamé, de garder des informations concernant le produit contenu dans la barquette et qui, de préférence, ne perturbe pas le rangement des barquettes dans un linéaire de présentation pour la vente du produit. The object of the invention is then, starting from a tray equipped or not with a cover, to provide a box making it possible to better preserve the started product, to keep information concerning the product contained in the tray and which, preferably, do not disturb the storage of the trays in a presentation shelf for the sale of the product.

A cet effet, la boîte qu'elle propose est équipée d'un couvercle articulé autour d'une zone charnière d'un côté de laquelle se trouve le couvercle, et de l'autre côté de laquelle se trouve une zone talon pour la fixation du couvercle sous le rebord périphérique de l'ouverture de la barquette, le couvercle proprement dit comportant des moyens pour le maintenir en position fermée et ne formant qu'une seule pièce avec la zone charnière et la zone talon. To this end, the box it offers is equipped with a cover hinged around a hinge area on one side of which is the cover, and on the other side of which is a heel area for fixing of the cover under the peripheral rim of the opening of the tray, the cover proper comprising means for keeping it in the closed position and forming only one piece with the hinge zone and the heel zone.

Ainsi, après une première ouverture de la boîte, le couvercle permet de refermer celle-ci et de conserver un produit entamé dans celleci. La fermeture du couvercle évite également la propagation d'odeurs. De plus, la barquette et le couvercle étant fixés l'un à l'autre, il n'y a pas de risque de perturbation dans des linéaires par désolidarisation de la barquette et du couvercle. Enfin, le couvercle peut servir de support pour porter la marque du produit conditionné dans la boîte ainsi que d'autres informations concernant ce produit. Ces informations restent alors accessibles à un consommateur jusqu'à ce que tout le produit soit consommé. Thus, after a first opening of the box, the lid makes it possible to close it and to keep a product started in it. Closing the cover also prevents the spread of odors. In addition, the tray and the cover being fixed to each other, there is no risk of disturbance in the shelves by separation of the tray and the cover. Finally, the cover can serve as a support to carry the mark of the product packaged in the box as well as other information concerning this product. This information then remains accessible to a consumer until all the product is consumed.

Bien entendu, ce couvercle n'empêche pas d'équiper la barquette d'un opercule soudé sur tout le pourtour du rebord périphérique. Of course, this cover does not prevent the tray from being fitted with a seal welded around the entire periphery of the peripheral rim.

Si le couvercle est réalisé dans un matériau transparent, cet opercule est même visible à travers le couvercle.If the cover is made of a transparent material, this cover is even visible through the cover.

Le couvercle venant se fixer sous le rebord périphérique de l'ouverture de la barquette, il peut pivoter de 1800 et dégager ainsi la totalité de l'ouverture de la barquette, permettant alors de retirer un éventuel opercule sans être gêné par le couvercle. The cover coming to be fixed under the peripheral rim of the opening of the tray, it can pivot by 1800 and thus release the whole of the opening of the tray, allowing then to remove a possible seal without being hampered by the cover.

Dans une forme de réalisation préférée, le couvercle comporte une zone plane destinée à venir au contact de la face supérieure du rebord périphérique en position fermée du couvercle, une zone s'étendant perpendiculairement à cette zone plane et sur tout le pourtour de celle-ci du côté de la barquette en position fermée du couvercle, ainsi que des bossages réalisés sur cette zone perpendiculaire à proximité de la zone plane, de telle sorte qu'en position fermée du couvercle, le rebord périphérique de la barquette se situe entre les bossages et la zone plane. In a preferred embodiment, the cover has a planar zone intended to come into contact with the upper face of the peripheral rim in the closed position of the cover, a zone extending perpendicular to this planar zone and around the entire periphery thereof. on the side of the tray in the closed position of the cover, as well as the bosses made on this perpendicular area near the flat area, so that in the closed position of the cover, the peripheral rim of the tray is located between the bosses and the flat area.

Le couvercle est ainsi muni de moyens de fermeture simples et efficaces. Dans le cas d'un couvercle rectangulaire, la charnière se situe sur un des quatre côtés du couvercle et les trois autres côtés sont munis avantageusement de bossages, afin de permettre une bonne fermeture du couvercle. The cover is thus provided with simple and effective closing means. In the case of a rectangular cover, the hinge is located on one of the four sides of the cover and the other three sides are advantageously provided with bosses, in order to allow a good closing of the cover.

Pour obtenir une bonne fixation de la zone talon sur le rebord périphérique, celle-ci est soudée au rebord périphérique, sur la face inférieure de celui-ci, et le matériau constitutif de cette zone talon est une matière synthétique compatible avec le matériau constitutif de la face extérieure de la barquette. To obtain good fixation of the heel area on the peripheral rim, the latter is welded to the peripheral rim, on the underside thereof, and the material of this heel area is a synthetic material compatible with the material of the outer face of the tray.

De préférence, la zone talon est soudée par ultra-sons au rebord périphérique.  Preferably, the heel area is welded by ultrasound to the peripheral rim.

Afin de pouvoir réaliser la soudure du couvercle lorsque ce dernier est en position fermée, la barquette est réalisée dans deux matériaux différents, la face intérieure de la barquette étant réalisée dans un matériau non compatible avec le matériau constitutif du couvercle et la face extérieure de la barquette étant réalisée dans un matériau compatible avec le matériau constitutif du couvercle. In order to be able to weld the lid when the latter is in the closed position, the tray is made of two different materials, the inner face of the tray being made of a material that is not compatible with the material of the lid and the outer face of the tray being made of a material compatible with the material of the cover.

Pour réaliser la soudure, on peut alors placer entre une enclume et une électrode, une sonotrode par exemple, d'un poste de soudure, la zone talon, le rebord périphérique et un bord du couvercle. Grâce aux compatibilité et incompatibilité de matériaux, lors du soudage, seule la zone talon est soudée au rebord périphérique. To carry out the welding, one can then place between an anvil and an electrode, a sonotrode for example, of a welding station, the heel zone, the peripheral rim and an edge of the cover. Thanks to the compatibility and incompatibility of materials, during welding, only the heel area is welded to the peripheral rim.

II existe plusieurs procédés pour fabriquer une boîte, telle que décrite ci-dessus. Selon l'invention, il est avantageux de fabriquer une telle boîte en mettant en oeuvre les étapes suivantes:
- mise en place d'un couvercle sur une barquette en position fermée à l'aide de vérins de positionnement, puis
- fixation de la zone talon sous le rebord périphérique de la barquette.There are several methods for manufacturing a box, as described above. According to the invention, it is advantageous to manufacture such a box by implementing the following steps:
- fitting of a lid on a tray in the closed position using positioning jacks, then
- fixing of the heel area under the peripheral rim of the tray.

Deux variantes de ce procédé sont proposées . Selon une première variante, pour réaliser une boîte, les étapes sont les suivantes
- mise en place de la barquette sur un support,
- dépose d'un couvercle sur la barquette,
- positionnement du couvercle sur la barquette en position fermée à l'aide de vérins de positionnement,
- rabattement de la zone talon autour de la charnière pour l'amener face au côté inférieur du rebord périphérique,
- assemblage de la zone talon au rebord périphérique.Two variants of this process are proposed. According to a first variant, to make a box, the steps are as follows
- placing the tray on a support,
- removal of a cover on the tray,
- positioning of the lid on the tray in the closed position using positioning jacks,
- folding of the heel area around the hinge to bring it facing the lower side of the peripheral rim,
- assembly of the heel area to the peripheral rim.

Selon une seconde variante, on effectue les étapes suivantes
- mise en place du couvercle en position ouverte sur un support prévu pour recevoir le couvercle et une barquette, de telle sorte que la zone talon repose avec jeu sur une barrette de positionnement,
- mise en place d'une barquette dans le support, de telle sorte que le rebord périphérique, du côté où doit être fixée la zone talon, repose sur cette dernière,
- articulation du couvercle proprement dit autour de la charnière pour venir en position fermée,
- fermeture de la boîte,
- positionnement exact du couvercle sur la barquette à l'aide de vérins de positionnement
- assemblage de la zone talon au rebord périphérique.According to a second variant, the following steps are carried out
- placing the cover in the open position on a support designed to receive the cover and a tray, so that the heel area rests with play on a positioning bar,
- placing a tray in the support, so that the peripheral rim, on the side where the heel area must be fixed, rests on the latter,
- articulation of the lid proper around the hinge to come in the closed position,
- closing the box,
- exact positioning of the lid on the tray using positioning jacks
- assembly of the heel area to the peripheral edge.

Dans cette seconde variante, la barrette de positionnement est avantageusement une contre-électrode d'un dispositif de soudure et l'assemblage de la zone talon au rebord périphérique est réalisée par soudage. In this second variant, the positioning bar is advantageously a counter-electrode of a welding device and the heel zone is assembled with the peripheral rim by welding.

Ces deux procédés permettent de réaliser des boîtes à partir de pièces (couvercle et barquette) présentant des tolérances de fabrication relativement larges. Afin d'avoir dans tous les cas un bon ajustement du couvercle sur la barquette, le couvercle est d'abord positionné par rapport à la barquette, pour assurer un bon positionnement des moyens de verrouillage du couvercle sur la barquette, avant de souder la zone talon sur le rebord périphérique. Suivant les dimensions de la barquette et du couvercle, la zone talon est alors soudée plus ou moins près du bord du rebord périphérique. These two methods make it possible to produce boxes from parts (lid and tray) having relatively wide manufacturing tolerances. In order to have in all cases a good fit of the lid on the tray, the lid is first positioned relative to the tray, to ensure proper positioning of the lid locking means on the tray, before welding the area heel on the peripheral rim. Depending on the dimensions of the tray and the lid, the heel area is then welded more or less close to the edge of the peripheral rim.

Enfin, I'invention propose un dispositif pour mettre en oeuvre la seconde variante du procédé. Ce dispositif peut être entièrement automatisé ou bien il peut comporter des postes de travail manuels. Finally, the invention proposes a device for implementing the second variant of the method. This device can be fully automated or it can include manual work stations.

Selon l'invention, ce dispositif comporte:
- un plateau tournant sur lequel sont disposés plusieurs supports destinés à recevoir un couvercle et une barquette,
- un premier poste de travail pour la mise en place d'un couvercle sur un support,
- un second poste de travail pour la mise en place d'une barquette sur le support déjà équipé du couvercle,
- une came de fermeture fixe permettant lors de la rotation du plateau d'amener le couvercle d'une position ouverte à une position fermée,
- un troisième poste équipé de vérins de positionnement pour positionner exactement le couvercle fermé par rapport à la barquette,
- un quatrième poste équipé de moyens pour fixer la zone talon au rebord périphérique, et
- un cinquième poste pour le déchargement des boîtes. According to the invention, this device comprises:
- a turntable on which are arranged several supports intended to receive a cover and a tray,
- a first work station for placing a cover on a support,
- a second work station for placing a tray on the support already fitted with the cover,
- a fixed closing cam allowing, during the rotation of the plate, to bring the cover from an open position to a closed position,
- a third station equipped with positioning jacks to exactly position the closed lid relative to the tray,
a fourth station equipped with means for fixing the heel area to the peripheral rim, and
- a fifth station for unloading boxes.

Suivant le mode de fixation choisi, les moyens de fixation sont par exemple un poste de soudure haute fréquence ou bien un poste de soudure ultra-sons ou bien encore une unité de collage, etc
De toute façon, I'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemples non limitatifs une boîte, un procédé et un dispositif pour la mise en oeuvre de ce procédé selon l'invention::
Figure 1 est une vue en perspective d'une boîte selon l'invention;

In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing, representing by way of nonlimiting examples a box, a method and a device for the implementation of this process according to the invention:
Figure 1 is a perspective view of a box according to the invention;
Figure 2 is an enlarged sectional view of this box;
Figure 3 is a perspective view of the lid of this box, the tray being shown in phantom
Figures 4 to 7 are views illustrating the process used to assemble the cover and the tray of a box such as that shown in Figures 1 and 2
FIG. 8 is a top view of a device for implementing a method of assembling a tray and a cover, and
Figure 9 is an elevational view of this device.

Les figures 1 à 3 représentent une boîte 1 selon l'invention. Figures 1 to 3 show a box 1 according to the invention.

Cette boîte 1 comporte une barquette 2 et un couvercle qui, d'une seule pièce, est constitué d'un couvercle proprement dit, d'une charnière 4 et d'une zone talon 5.This box 1 comprises a tray 2 and a cover which, in a single piece, consists of a cover proper, a hinge 4 and a heel area 5.

La barquette 2 sert de contenant et elle est destinée à recevoir un produit alimentaire, tel par exemple une portion de fromage. Dans l'exemple de réalisation non limitatif représenté au dessin, cette barquette 2 a la forme d'une portion de cylindre avec deux parois triangulaires, une paroi rectangulaire et une paroi en forme de section de cylindre. Elle présente une ouverture rectangulaire autour duquel se trouve un rebord périphérique 6 disposé dans le plan de l'ouverture. The tray 2 serves as a container and it is intended to receive a food product, such as for example a portion of cheese. In the nonlimiting embodiment shown in the drawing, this tray 2 has the shape of a cylinder portion with two triangular walls, a rectangular wall and a wall in the shape of a cylinder section. It has a rectangular opening around which there is a peripheral rim 6 arranged in the plane of the opening.

Cette barquette 2 est réalisée dans un matériau bi-couche. La face interne 7 de la barquette, destinée à être au contact avec le produit à conditionner, ainsi que la face supérieure du rebord 6 sont en polyéthylène. La face externe 8 de la barquette et la face inférieure du rebord 6 sont en polychlorure de vinyle. Le couvercle est réalisé en polychlorure de vinyle.  This tray 2 is made of a two-layer material. The internal face 7 of the tray, intended to be in contact with the product to be packaged, as well as the upper face of the rim 6 are made of polyethylene. The outer face 8 of the tray and the underside of the rim 6 are made of polyvinyl chloride. The cover is made of polyvinyl chloride.

Le couvercle 3 est de forme rectangulaire et comporte une zone plane 9 qui repose sur le rebord 6 en position fermée du couvercle (figure 2). Cette zone plane 9 est annulaire et le centre du couvercle 10 est en relief par rapport à cette zone 9. The cover 3 is rectangular in shape and has a flat area 9 which rests on the flange 6 in the closed position of the cover (FIG. 2). This planar zone 9 is annular and the center of the cover 10 is in relief relative to this zone 9.

Autour de la zone plane 9 et sur tout son pourtour s'étend une zone 11 perpendiculaire à cette zone plane 9. Lorsque le couvercle 3 est fermé, cette zone perpendiculaire 1 1 se situe du côté de la barquette 2, par rapport à la zone plane 9 et au rebord 6. Around the flat zone 9 and around its entire periphery extends a zone 11 perpendicular to this flat zone 9. When the cover 3 is closed, this perpendicular zone 1 1 is situated on the side of the tray 2, with respect to the zone plane 9 and at the edge 6.

La charnière 4 est rattachée à un côté de couvercle proprement dit 3, sur un bord de la zone perpendiculaire 1 1 opposé à la zone plane 9. The hinge 4 is attached to a side of the lid proper 3, on an edge of the perpendicular zone 11 opposite to the flat zone 9.

Sur les trois autres côtés du couvercle proprement dit, la zone perpendiculaire 1 1 présente à chaque fois deux bossages 12 faisant saillie vers l'intérieur du couvercle. Ces bossages 12 sont situés à proximité de la zone plane 9. Ainsi, lorsque le couvercle est fermé, le rebord 6 se retrouve entre la zone plane 9 et les bossages 12 qui maintiennent le couvercle fermé.On the other three sides of the cover itself, the perpendicular area 11 has each time two bosses 12 projecting towards the inside of the cover. These bosses 12 are located near the flat area 9. Thus, when the cover is closed, the flange 6 is found between the flat area 9 and the bosses 12 which keep the cover closed.

Pour compenser la hauteur de la zone perpendiculaire 1 1 du couvercle 3, la zone talon 5 comporte une rainure 13 dont la paroi 14 constituant le fond est soudée à la face inférieure du rebord 6. To compensate for the height of the perpendicular zone 11 of the cover 3, the heel zone 5 has a groove 13 whose wall 14 constituting the bottom is welded to the underside of the rim 6.

Les figures 4 à 7 illustrent un procédé pour assembler une barquette 2 et son couvercle. Figures 4 to 7 illustrate a method for assembling a tray 2 and its cover.

La figure 4 montre un support 30 présentant deux logements,
I'un pour recevoir une barquette 2, I'autre un couvercle 3,4,5. Le rebord 6 de la barquette devant recouvrir la zone talon 5, le couvercle 3, solidaire de la zone talon 5, est mis en place dans le logement prévu à cet effet avant de mettre dans son logement la barquette 2. Le couvercle 3,4,5 se retrouve en position ouverte par rapport à la barquette 2.FIG. 4 shows a support 30 having two housings,
One to receive a tray 2, the other a lid 3,4,5. The rim 6 of the tray having to cover the heel area 5, the cover 3, integral with the heel area 5, is placed in the housing provided for this purpose before putting the tray 2. The cover 3,4 , 5 is found in the open position relative to the tray 2.

La rainure 13 de la zone talon est placée sur une barrette 31, faisant saillie de la surface du support 30. Un jeu latéral j relativement important existe entre la barrette 31 et les parois de la rainure 13. The groove 13 in the heel area is placed on a bar 31, projecting from the surface of the support 30. A relatively large lateral clearance j exists between the bar 31 and the walls of the groove 13.

L'opération suivante consiste à fermer le couvercle 3 en laissant la zone talon 5 au contact de la face inférieure du rebord 6, c'està-dire en articulant le couvercle 3 autour de la charnière 4 (figure 5). The following operation consists in closing the cover 3 leaving the heel area 5 in contact with the underside of the rim 6, that is to say by hinging the cover 3 around the hinge 4 (FIG. 5).

Une fois le couvercle 3,4,5 en position fermée, il est positionné avec exactitude par rapport à la barquette 2. Un premier vérin de positionnement 32, vient appuyer le couvercle 3 en direction de la barquette 2 afin de bien placer le rebord 6 de la barquette par rapport aux bossages 12 du couvercle. Cette action du premier vérin 32 permet de positionner les bossages 12 placés du côté opposé à la charnière. Once the lid 3,4,5 in the closed position, it is positioned exactly relative to the tray 2. A first positioning cylinder 32 presses the cover 3 in the direction of the tray 2 in order to properly place the flange 6 of the tray relative to the bosses 12 of the cover. This action of the first jack 32 makes it possible to position the bosses 12 placed on the side opposite the hinge.

Un second vérin, non représenté sur les figures, disposé dans le même plan que le premier vérin 32 parallèlement à la zone charnière 4, permet de positionner latéralement les bossages 12 du couvercle. A second cylinder, not shown in the figures, arranged in the same plane as the first cylinder 32 parallel to the hinge zone 4, allows the bosses 12 of the cover to be positioned laterally.

Un troisième vérin de positionnement 33 maintient le couvercle en position. A third positioning cylinder 33 holds the cover in position.

Une fois le couvercle 3 bien positionné (figure 6), la zone de talon peut être soudée au rebord 6. Une électrode 34 d'un poste de soudure (non représenté) fait alors face à la barrette 31 faisant office de contre-électrode et vient se poser entre le couvercle proprement dit 3 et la charnière 4. L'opération de soudage est alors effectuée. Au cours de celleci, seule la zone talon 5 est soudée au rebord 6, car le matériau (polychlorure de vinyle) constitutif du couvercle n'est pas compatible avec le matériau (polyéthylène) constitutif de la face supérieure du rebord 6. Once the cover 3 is correctly positioned (FIG. 6), the heel area can be welded to the rim 6. An electrode 34 of a welding station (not shown) then faces the bar 31 acting as a counter-electrode and comes to rest between the lid proper 3 and the hinge 4. The welding operation is then carried out. During this, only the heel zone 5 is welded to the rim 6, because the material (polyvinyl chloride) constituting the cover is not compatible with the material (polyethylene) constituting the upper face of the rim 6.

Lorsque la soudure est réalisée (figure 7), les trois vérins et l'électrode s'éloignent et la boîte 1 ainsi réalisée peut sortir du support 30. When the welding is carried out (FIG. 7), the three jacks and the electrode move away and the box 1 thus produced can come out of the support 30.

Les figures 8 et 9 représentent un dispositif permettant de mettre en oeuvre le procédé décrit ci-dessus. Figures 8 and 9 show a device for implementing the method described above.

Ce dispositif comporte un plateau tournant 50 sur lequel sont disposés huit supports 30. This device comprises a turntable 50 on which eight supports 30 are arranged.

Un premier poste de travail 51 est équipé d'un dépileur 52. Ce dernier comporte une pile 53 de couvercles qu'il dépose un à un sur un support 30, chaque fois qu'un support 30 vide passe sous lui. A first work station 51 is equipped with a destacker 52. The latter comprises a stack 53 of covers which it deposits one by one on a support 30, each time an empty support 30 passes under it.

Le plateau tournant 50 tourne dans le sens indiqué par la flèche. Le support 30 sur lequel a été déposé un couvercle 3,4,5 passe alors dans un second poste de travail 54. A ce poste, une barquette 2 est déposée dans le support 30 comme représenté à la figure 4. La barquette 2 peut être déposée manuellement ou bien automatiquement. The turntable 50 rotates in the direction indicated by the arrow. The support 30 on which a cover 3,4,5 has been deposited then passes into a second work station 54. At this station, a tray 2 is deposited in the support 30 as shown in FIG. 4. The tray 2 can be filed manually or automatically.

Le support 30 muni du couvercle 3,4,5 et de la barquette 2 est alors entraîné en rotation par le plateau tournant 50. Au cours de cette rotation, le couvercle 3 prend appui contre une came de fermeture 55 qui est fixe.  The support 30 provided with the cover 3,4,5 and the tray 2 is then driven in rotation by the turntable 50. During this rotation, the cover 3 bears against a closing cam 55 which is fixed.

Lorsque le couvercle 3 est fermé, le support 30 arrive à un troisième poste de travail 57. Ce poste 57 comporte trois vérins de positionnement fonctionnant comme décrit ci-dessus. When the cover 3 is closed, the support 30 arrives at a third work station 57. This station 57 comprises three positioning jacks operating as described above.

Un poste de soudure 57 constitue un quatrième poste de travail. C'est à ce poste qu'est réalisée la soudure. A welding station 57 constitutes a fourth work station. This is where welding takes place.

Le déchargement des boîtes 1 fabriquées par le dispositif est réalisé à un cinquième 58 et sixième 59 poste de travail. Les boîtes 1 sont alors déchargées, par éjection automatique par exemple, sur un convoyeur à bande 60. The boxes 1 produced by the device are unloaded at a fifth 58 and sixth 59 work station. The boxes 1 are then unloaded, for example by automatic ejection, on a belt conveyor 60.

Les boîtes 1 sans défaut, ou avec des défauts moindres, sont déchargées au cinquième poste de travail 58 et celles présentant des défauts plus importants sont déchargées au sixième poste 59. The boxes 1 without defect, or with lesser faults, are unloaded at the fifth work station 58 and those with larger faults are unloaded at the sixth work station 59.

Comme il va de soi, I'invention ne se limite pas à la boîte, au procédé et au dispositif décrits ci-dessus à titre d'exemple non limitatif; elle en embrasse au contraire toutes les variantes. It goes without saying that the invention is not limited to the box, the method and the device described above by way of nonlimiting example; on the contrary, it embraces all its variants.

Ainsi, la boîte selon l'invention peut comporter une barquette parallélépipèdique, ou bien aussi présenter une ouverture qui ne soit pas rectangulaire (triangulaire ou plus généralement polygonale par exemple). Thus, the box according to the invention may include a parallelepiped tray, or also have an opening which is not rectangular (triangular or more generally polygonal for example).

Les bossages réalisés pour maintenir le couvercle fermé peuvent être remplacés par d'autres moyens de fermeture : bossages et creux de forme complémentaire réalisés respectivement sur le rebord périphérique et sur la zone plane du couvercle, languette adhésive repositionnable, etc. The bosses made to keep the cover closed can be replaced by other closing means: bosses and recesses of complementary shape made respectively on the peripheral rim and on the flat area of the cover, repositionable adhesive tab, etc.

Dans l'exemple de réalisation, la zone talon est soudée au rebord périphérique. Cependant, une boîte dont la zone talon serait collée au rebord présenterait les mêmes avantages que la boîte décrite ci-dessus. In the exemplary embodiment, the heel zone is welded to the peripheral rim. However, a box with the heel area glued to the rim would have the same advantages as the box described above.

Le procédé décrit un mode de réalisation préférentiel. D'autres procédés peuvent permettre de réaliser une boîte selon l'invention. Il est par exemple possible de positionner tout d'abord le couvercle sur la barquette et ensuite d'articuler la zone de talon pour qu'elle vienne sous le rebord périphérique. The method describes a preferred embodiment. Other methods can make it possible to produce a box according to the invention. It is for example possible to first position the cover on the tray and then to articulate the heel area so that it comes under the peripheral rim.

Le couvercle peut bien entendu être soudé en position ouverte. The cover can of course be welded in the open position.

Dans la description ci-dessus, la barquette n'est pas munie d'un opercule soudé sur le rebord périphérique. Cet opercule peut être rajouté sur la barquette, de préférence avant de fixer le couvercle, sans pour autant sortir du domaine de l'invention.  In the description above, the tray is not provided with a seal welded to the peripheral rim. This cover can be added to the tray, preferably before fixing the cover, without departing from the scope of the invention.

Ainsi, un dispositif tel que décrit peut venir équiper une chaîne de conditionnement de produits alimentaires sans qu'il soit nécessaire de modifier la chaîne existante. Le dispositif est alors placé en bout de chaîne et il équipe les barquettes remplies et operculées d'un couvercle. Thus, a device as described can be fitted to a chain for packaging food products without the need to modify the existing chain. The device is then placed at the end of the chain and it equips the filled and sealed trays with a cover.

L'opercule permet une bonne conservation du produit jusqu'à la première ouverture de la barquette et constitue une fermeture inviolable. Le couvercle permet quant à lui de conserver le produit entamé, après la première ouverture de la barquette. Le couvercle permet également de conserver des informations relatives au produit, comme par exemple sa marque, sa composition, etc même lorsque le produit est entamé. The lid allows a good conservation of the product until the first opening of the tray and constitutes a tamper-evident closure. The cover allows to keep the product started, after the first opening of the tray. The cover also makes it possible to store information relating to the product, such as for example its brand, its composition, etc. even when the product is started.
