Abstract

A dish made of sheet material which can be folded flat for storage prior to use is made from a blank shaped so that pairs of 'V' shaped panels can be generated for extra support at each corner between the sidewalls and the end panels of the dish. Support is provided by one folded face which is bonded against the external face of the adjacent sidewall and another folded face inclined inwards adjacent to the end panel. Pref. the fold zones are slotted and their focal zones are chipped: the openings at the focal points serve to prevent mutual interference by the folds and to drain any juice or condensn. from the base of the box, and/or provide ventilation. Esp. applicable to dishes for holding food and made from polyethylene-coated card.

Description

Lsinvintion est relative à une barquette en carton ou analogue
Les produits alimentaires de toute nature sont souvent conditionnés dans des barquettes.The invention relates to a cardboard container or the like
Food products of all kinds are often packaged in trays.

La qualité essentielle quDattend le consommateur d'une barquette est qu'elle soit suffisamment solide pour contenir des denrées alimentaires sans risque de se déformer au cours du transport. Mais cette qualité est difficile à concilier avec celle souhaitée par le commerçant qui est de pouvoir stocker les barquettes à plat tout en ayant un minimum d'opérations à effectuer pour les amener en condition d0uti- lisation
La barquette selon l'invention présente ces deux qualités.The essential quality that the consumer expects from a tray is that it is strong enough to contain foodstuffs without the risk of deforming during transport. But this quality is difficult to reconcile with that desired by the trader which is to be able to store the trays flat while having a minimum of operations to be carried out to bring them into working condition.
The tray according to the invention has these two qualities.

Elle est caractérisée en ce que le flan à partir duquel elle est réalisée présente0 pour raccorder deux parois latév rales adjacentes0 des volets triangulaires ayant une ardue commune dont l'un est replié vers l'extérieur avec sa face externe appliquée, notamment par collage contre la face externe de la paroi latérale à laquelle il est attaché0 l'arête commune à ce volet et à cette paroi latérale consti- tuant un appui pour la paroi latérale adjacente. It is characterized in that the blank from which it is produced is present to connect two adjacent lateral walls to triangular flaps having a common ardue, one of which is folded outwards with its external face applied, in particular by gluing against the external face of the side wall to which it is attached to the edge common to this flap and to this side wall constituting a support for the adjacent side wall.

Pour mettre à plat une telle barquette, il suffitd'appli quer contre le fond les parois latérales auxquelles sont accolés des volets, et ensuite de rabatte les autres parois laté- rales. To lay such a container flat, it suffices to press the side walls against which the flaps are attached, and then to fold down the other side walls.

Dans une réalisation les lignes de pliage, notamment celles du fond, présentent des fentes ou découpes selon leur longueur, ce qui facilite le pliage. Ces fentes ou découpes assurent également une aération du produit alimentaire se trouvant dans la barquette et permettent l'évacuation de liquides, par exemple les jus produits par les volailles crues. In one embodiment, the fold lines, in particular those at the bottom, have slots or cutouts along their length, which facilitates folding. These slots or cutouts also provide ventilation for the food product in the tray and allow the evacuation of liquids, for example the juices produced by raw poultry.

D'autres caractéristiques de l'invention apparaitront avec la description de certains de ses modes de réalisation, celle-ci étant effectuée en se référant aux dessins ci-annexés sur lesquels :
- la figure 1 montre un flan d'une barquette selon l'in- vention qui est destinée à contenir une volaille crue;
- la figure 2 est une vue en perspective d'une barquette en condition d'utilisation
- la figure 3 montre une barquette en condition aplatie. Other characteristics of the invention will appear with the description of some of its embodiments, this being carried out with reference to the attached drawings in which:
- Figure 1 shows a blank of a tray according to the invention which is intended to contain raw poultry;
- Figure 2 is a perspective view of a container in use condition
- Figure 3 shows a tray in flattened condition.

Le flanc 1 -qui est en carton enduit de polyéthylène afin de satisfaire aux conditions d'hvaiène sénéralement prescrites ou l'emballage - pour le conditionnement/des produits alimentaires- comporte une paroi de fond 2 ayant la forme générale d'un trapèze isocèle dont les côtés 3 et 4 sont les plus courts et quatre parois latérales: une paroi 5 ayant le côté 3 en commun avec le fond 2, une paroi 7 rattachée au fond selon une ligne 6, une paroi 8 attachée au fond 2 selon le côté 4 de ce dernier, et une paroi latérale 10 dont le bord intérieur est le côté 9 dudit fond. The sidewall 1 -which is made of cardboard coated with polyethylene in order to satisfy the generally prescribed conditions of henna or the packaging - for packaging / food products - comprises a bottom wall 2 having the general shape of an isosceles trapezium of which the sides 3 and 4 are the shortest and four side walls: a wall 5 having the side 3 in common with the bottom 2, a wall 7 attached to the bottom along a line 6, a wall 8 attached to the bottom 2 along the side 4 of the latter, and a side wall 10 whose inner edge is the side 9 of said bottom.

Le flan 1 présente un axe longitudinal la de symétrie. I1 suffit donc de décrire une moitié de ce flan, par exemple celle comprenant la paroi 7, les parties de l'autre moitié portant les mêmes références mais frappées de l'indice a. The blank 1 has a longitudinal axis 1a of symmetry. It is therefore sufficient to describe one half of this blank, for example that comprising the wall 7, the parts of the other half bearing the same references but marked with the index a.

La paroi 7 présente un bord externe de forme incurvée avec un renflement 11 plus près de la paroi 8 que de la paroi 5 et dont la courbure correspond sensiblement à celle présentée par une volaille dans la zone des ailes. The wall 7 has an outer edge of curved shape with a bulge 11 closer to the wall 8 than to the wall 5 and whose curvature corresponds substantially to that presented by a poultry in the area of the wings.

La paroi 8 est séparée d'une languette 12 qui, en condition érigée de la barquette, la prolonge vers le haut par une ligne de rainage ou pliage 13. La languette 12, qui est plus étroite, dans la direction perpendiculaire à l'axe la que la paroi 8 est destinée à recouvrir la partie avant de la volaille. The wall 8 is separated from a tongue 12 which, in the erected condition of the tray, extends it upwards by a creasing or folding line 13. The tongue 12, which is narrower, in the direction perpendicular to the axis the that the wall 8 is intended to cover the front part of the poultry.

Un rabat 15 est attaché à la paroi 5 selon son bord supérieur 14. Ce rabat présente deux parties 16 et 17 séparées par une ligne de rainage 18 parallèle à la ligne 14. I1 est destiné à recouvrir la partie arrière de la volaille. Le rabat 15 est, dans la direction perpendiculaire à l'axe la, de plus faible largeur que la base 3 de la paroi 5. A flap 15 is attached to the wall 5 along its upper edge 14. This flap has two parts 16 and 17 separated by a crease line 18 parallel to the line 14. I1 is intended to cover the rear part of the poultry. The flap 15 is, in the direction perpendicular to the axis la, of narrower width than the base 3 of the wall 5.

La paroi 8 est bordée par une ligne de rainage 20 quasiperpendiculaire à la ligne 4 qui constitue également le bord d'un volet 21 de forme générale triangulaire séparé par une autre ligne de rainage 22 passant par le point A, à 1' intersection des côtés 4 et 6 du fond 2, d'un autre volet triangulaire 23 présentant un côté 24 qui est une ligne de rainage perpendiculaire à la ligne 20 et forme une arête de la paroi 7 passant par le point A. The wall 8 is bordered by a crease line 20 quasiperpendicular to line 4 which also constitutes the edge of a flap 21 of generally triangular shape separated by another crease line 22 passing through point A, at the intersection of the sides 4 and 6 of the bottom 2, of another triangular flap 23 having a side 24 which is a crease line perpendicular to the line 20 and forms an edge of the wall 7 passing through the point A.

Le volet 21 présente un bord libre 25 sensiblement en prolongement de la ligne 13 séparant la paroi 8 de la languette 12, tandis que le bord libre 26 du volet triangulaire 23 se raccorde au bord libre 11' de la paroi 7. Les lignes 20 et 24 ont pratiquement la même longueur et l'angle entre les lignes 20 et 22 est de l'ordre de 450.  The flap 21 has a free edge 25 substantially in line with the line 13 separating the wall 8 from the tongue 12, while the free edge 26 of the triangular flap 23 is connected to the free edge 11 'of the wall 7. The lines 20 and 24 have practically the same length and the angle between the lines 20 and 22 is of the order of 450.

Des volets triangulaires 30, 31 et 32 raccordent de même la paroi 7 à la paroi 5. Une ligne de rainage 33 sépare la paroi 7 du volet 30 ; elle est quasi-perpendiculaire au côté 6, étant destinée à former une arête verticale de la paroi 7 en condition érigée La ligne de rainage 35 se trouvant a la limite entre les volets triangulaires 31 et 32 est, dans le prolongement de ladite ligne 6. La ligne de rainage 34 entre les volets 30 et 31 forme un angle d'eniriron 550 avec la ligne 33, tandis que l'angle entre la ligne 35 et la ligne 36 séparant la paroi 5 du volet 32 est de l'ordre de 300. Triangular flaps 30, 31 and 32 likewise connect the wall 7 to the wall 5. A crease line 33 separates the wall 7 from the flap 30; it is almost perpendicular to the side 6, being intended to form a vertical edge of the wall 7 in erected condition The crease line 35 located at the limit between the triangular flaps 31 and 32 is, in the extension of said line 6. The crease line 34 between the flaps 30 and 31 forms an angle of about 550 with the line 33, while the angle between the line 35 and the line 36 separating the wall 5 of the flap 32 is of the order of 300 .

Les bords libres 70 et 71 des volets triangulaires 31 et 32sont en prolongement l'un de l'autre et en prolongement de la ligne de rainage 14 séparant le rabat 15 de la paroi 5. The free edges 70 and 71 of the triangular flaps 31 and 32 are in extension of one another and in extension of the crease line 14 separating the flap 15 from the wall 5.

Le bord libre 72 du volet triangulaire 30 est arrondi au voisinage de l'extrémité de la ligne de rainage 34 oppose au point B commun aux côtés 3 et 6 du fond 2. The free edge 72 of the triangular flap 30 is rounded in the vicinity of the end of the crease line 34 opposite the point B common to the sides 3 and 6 of the bottom 2.

Les lignes de rainage séparant les paroIs latérales, d'une part du fond 2 et, d'autre part, des volets,présentent des fentes 40, 41, 40', 41', etc. facilitant le pliage et assurant en même temps une aération pour le produit se trouvant dans la barquette. En outre, ces fentes 40, 41 ... permettent l'évacuation du liquide qui peut s'6couler-de la volaille crue. Des découpes 42, 43, 44 et 45 sont également prévues au voisinage des sommets du fond 2. The creasing lines separating the side walls, on the one hand from the bottom 2 and, on the other hand, flaps, have slots 40, 41, 40 ', 41', etc. facilitating folding and at the same time ensuring ventilation for the product in the tray. In addition, these slots 40, 41 ... allow the evacuation of the liquid which can flow-from the raw poultry. Cutouts 42, 43, 44 and 45 are also provided in the vicinity of the vertices of the bottom 2.

La fabrication de la barquette s'effectue de la façon suivante
La face externe du volet 23 est appliquée contre la face externe de la paroi 7 contre laquelle elle est maintenue par collage. De même, le volet 30 est appliqué contre la paroi 7 par collage de sa face externe contre la face externe de cette paroi. Ainsi, la paroi 7 est renforcée au voisinage de ses arêtes 24 et 33.The manufacturing of the tray is carried out as follows
The external face of the flap 23 is applied against the external face of the wall 7 against which it is held by gluing. Likewise, the flap 30 is applied against the wall 7 by bonding its external face against the external face of this wall. Thus, the wall 7 is reinforced in the vicinity of its edges 24 and 33.

La barquette est livrée au commerçant en condition plate (fig. 3) les parois 7 et 10 appliquées contre le fond 2 et les parois 5 et 8 également rabattues
Lorsque la barquette est érigé (fig. 2 > l'arête 24 forme un appui pour la paroi 8, tandis que l'arête 33 forme un appui pour la paroi 5. Ces arêtes empêchent ainsi que les pa- rois 5 et 8 ne se rabattent contre le fond 2. Réciproquement, le contact & frottement des parois 5 et 8 avec lesdites arêtes contribue également au maintien des parois 7 et 10.The tray is delivered to the trader in flat condition (fig. 3) the walls 7 and 10 applied against the bottom 2 and the walls 5 and 8 also folded down
When the tray is erected (fig. 2> the edge 24 forms a support for the wall 8, while the edge 33 forms a support for the wall 5. These edges thus prevent walls 5 and 8 from being fold back against the bottom 2. Conversely, the contact & friction of the walls 5 and 8 with said edges also contributes to the maintenance of the walls 7 and 10.

En raison de l'inclinaison vers l'intérieur des lignes 36 et 36a bordant la paroi 5, les arêtes 33 et 33a de la barquette en condition d'utilisation sont également inclinées vers l'intérieur, -l'inclinaison étant au moins égale à celle des arêtes 36 et 36a. De ce fait, les parois 7 et 10 présentent au voisinage des arêtes 33 et 33a une partie incurvée vers l'intérieur, respectivement 81 et 82, ce qui est favorable au maintien de la volaille dans la barquette. Due to the inward inclination of the lines 36 and 36a bordering the wall 5, the edges 33 and 33a of the tray in condition of use are also inclined inward, the inclination being at least equal to that of edges 36 and 36a. Therefore, the walls 7 and 10 have in the vicinity of the edges 33 and 33a an inwardly curved portion, respectively 81 and 82, which is favorable for keeping the poultry in the tray.

Lorsque la barquette est érigée, le carton a tendance à revenir à sa position d'origine ; ainsi, les volets 21a et 23a (symétriques des volets 21 et 23 par rapport à la ligne la) ne restent-pas appliqués l'un contre l'autre et délimitent entre eux un intervalle 80. Pour la même raison, lorsque la barquette est érigée le volet 30 ne reste pas appliqué contre le volet 31. Il en résulte que les parois 7 et 10 sont inclinées vers l'intérieur, ce qui est également favorable au maintien de la volaille. When the tray is erected, the carton tends to return to its original position; thus, the flaps 21a and 23a (symmetrical of the flaps 21 and 23 with respect to the line la) do not remain applied one against the other and delimit between them an interval 80. For the same reason, when the tray is erected the flap 30 does not remain applied against the flap 31. It follows that the walls 7 and 10 are inclined inward, which is also favorable for the maintenance of poultry.

Pour la vente, une pellicule transparente entoure la barquette et la volaille qu'elle contient et maintient celle-ci. For sale, a transparent film surrounds the tray and the poultry it contains and maintains it.

La barquette est stockable à plat, les parois 7 et 10 étant appliquées contre le fond 2 et les parois 8 et 5 contre ces parois 7 et 10, et la disposition de cette barquette en condition i'utilisation s'effectue simplement en relevant les parois 5 et 8. The tray can be stored flat, the walls 7 and 10 being applied against the bottom 2 and the walls 8 and 5 against these walls 7 and 10, and the arrangement of this tray in conditions of use is carried out simply by raising the walls 5 and 8.

La forme et les dimensions de la barquette peuvent bien entendu varier selon la forme et les dimensions du produit qu'elle est destinée à contenir. Ainsi, en variante, le fond 2 présente une forme rectangulaire. The shape and dimensions of the tray can of course vary depending on the shape and dimensions of the product it is intended to contain. Thus, as a variant, the bottom 2 has a rectangular shape.

En variante également, la barquette est dépourvue des fentes 40, 41, 40', 41: et des découpes 42 à 45 et est ainsi étanche, permettant de retenir des liquides tels que des -jus ou sauces.  Also in a variant, the tray is devoid of the slots 40, 41, 40 ′, 41: and of the cutouts 42 to 45 and is thus sealed, making it possible to retain liquids such as juices or sauces.
