Abstract

A sealed rectangular parallelepiped polypropylene conditioning package with fast tear-off opening for pasty products likely to melt into a semi-liquid state, in particular cheese, includes a first sheet (1) cut out along a suitable contour and having a rectangular shell-type shape for receiving the product and for providing a gripping corner (2) for opening the package, a cover sheet and two tear-off strips (5,6). The gripping corner (2) has a triangular projection formed on one of the sides of the first sheet cut out into an octagonal shape and the tear-off strips (5, 6) form a pointed U shape whereof the tip is located in the triangular projection, thereby making it easy and simple to open.

Description

La présente, invention concerne un emballage de conditionnement parallélépipédique rectangulaire étanche en polypropylène à ouverture rapide par déchirement pour produit pâteux susceptible d'être amené dans un état au moins semi-liquide, en particulier du fromage, cet emballage étant composé de deux feuilles minces, à savoir une première feuille découpée suivant un contour approprié et conformé en coquille rectangulaire destinée à recevoir le produit et de manière à présenter un coin de préhension pour l'ouverture de l'emballage, et une deuxième feuille découpée au moins aux dimensions du fond de la coquille et destinée à être posée à plat sur le produit et sur laquelle les côtés de la coquille sont pliés, rabattus et thermosoudés en laissant libre le coin de préhension, et de deux bandes de déchirement disposées et fixées sur la première feuille de telle sorte qu'elles sont entraînées lors d'une traction sur le coin de préhension.The present invention relates to a tight-fitting polypropylene rectangular rectangular parallelepiped packaging packaging for a pasty product capable of being brought into an at least semi-liquid state, in particular cheese, this package being composed of two thin sheets, that is to say a first sheet cut into a suitable contour and shaped as a rectangular shell intended to receive the product and so as to have a gripping wedge for the opening of the package, and a second sheet cut at least to the dimensions of the bottom of the the shell and intended to be laid flat on the product and on which the sides of the shell are folded, folded and heat-sealed leaving free the gripping corner, and two tear strips arranged and fixed on the first sheet so that they are driven when pulling on the grip.

Un emballage de ce type est connu du brevet FR 2 499 025 . Dans cet emballage, la première feuille est munie de deux bandes de déchirement parallèles et le coin de préhension est formé par le pliage à 45° de deux moitiés de l'un des côtés de la feuille découpée. Ce pliage a pour effet d'amener les extrémités des deux bandes de déchirement dans une zone thermosoudée relativement éloignée de l'extrémité du coin de préhension. Lors d'une traction sur ce coin de préhension, on risque de déchirer le coin de préhension avant d'exercer une traction sur les bandes de déchirement et par conséquent d'échouer dans l'ouverture de l'emballage.A package of this type is known from the patent FR 2,499,025 . In this package, the first sheet is provided with two parallel tear strips and the gripping wedge is formed by 45 ° folding two halves of one side of the cut sheet. This folding has the effect of bringing the ends of the two tear strips into a heat-welded zone relatively far from the end of the gripping wedge. When pulling on this gripping corner, there is a risk of tearing the gripping wedge before pulling on the tear strips and consequently failing in the opening of the package.

Dans un emballage dérivé du précédent, dans lequel le coin est également formé par deux plis à 45°, les bandes parallèles de déchirement sont plus proches du centre de l'emballage et présentent un élargissement en direction de ce centre de telle sorte qu'elles sont situées très proches de l'extrémité du coin de préhension lors de la formation de ce coin. Par contre, une partie des côtés du coin replié à 45° est soudée sur la deuxième feuille en formant un pli offrant une résistance accrue au déchirement. Un tel emballage réalisé en polypropylène (PP) est très difficile à déchirer en raison de ce pli, raison pour laquelle cet emballage est réalisé en polypropylène orienté (OPP).In a package derived from the previous one, in which the corner is also formed by two 45 ° folds, the parallel strips of tearing are closer to the center of the package and have an enlargement towards this center so that they are located very close to the end of the wedge when forming this corner. On the other hand, a portion of the sides of the 45 ° folded corner is welded to the second sheet forming a fold providing increased tear resistance. Such packaging made of polypropylene (PP) is very difficult to tear because of this fold, which is why this packaging is made of oriented polypropylene (OPP).

Du brevet FR 2 362 765 , on connaît en outre un emballage de conditionnement parallélépipédique rectangulaire muni d'une bande de déchirement en forme de diapason dont le manche très court forme une languette de préhension pour le déchirement. La saisie de cette courte languette n'est pas aisée.From the patent FR 2,362,765 In addition, a rectangular parallelepiped packaging package is known which is provided with a tuning fork-shaped tear tape whose very short handle forms a gripping tab for tearing. Entering this short tab is not easy.

FR 2 198 469 divulgue un emballage suivant la préambule de la revendication 1. FR 2 198 469 discloses a package according to the preamble of claim 1.

L'invention a pour but de faciliter l'ouverture d'un emballage de conditionnement réalisé en polypropylène (PP ou OPP).The invention aims to facilitate the opening of a packaging packaging made of polypropylene (PP or OPP).

L'emballage selon l'invention est caractérisé en ce que le coin de préhension est formé d'une saillie triangulaire formée sur l'un des côtés de la première feuille découpée en octogone et en ce que les bandes de déchirement forment un U pointu dont la pointe est située dans ladite saillie triangulaire.The packaging according to the invention is characterized in that the gripping wedge is formed of a triangular projection formed on one of the sides of the first octagonal cut sheet and in that the tear strips form a pointed U of which the tip is located in said triangular projection.

Ainsi, lorsqu'on saisit le coin de préhension, on saisit également les deux bandes de déchirement et l'on peut ouvrir l'emballage sans rencontrer la résistance d'un pli.Thus, when grasping the gripping corner, the two tear strips are also grasped and the package can be opened without encountering the resistance of a fold.

Avantageusement, le côté de la première feuille muni du coin de préhension présente deux amorces de déchirement. Ces amorces de déchirement sont avantageusement constituées d'entailles situées dans le prolongement des côtés du coin de préhension.Advantageously, the side of the first sheet provided with the gripping wedge has two tearing primers. These tearing primers advantageously consist of notches located in the extension of the sides of the gripping wedge.

La bande de déchirement est avantageusement située à l'intérieur de la coquille, de telle sorte qu'elle est cachée, et s'étend le long des côtés du fond de la coquille de manière à obtenir une ouverture intégrale.The tear strip is advantageously located inside the shell, so that it is hidden, and extends along the sides of the bottom of the shell so as to obtain an integral opening.

Pour la formation de la coquille et du conditionnement du produit, on peut utiliser le procédé et l'installation décrits dans le brevet CH 690 996 ( EP 0803 439 ) avec les adaptations qui s'imposent.For the formation of the shell and the packaging of the product, it is possible to use the method and the installation described in the patent CH 690 996 ( EP 0803 439 ) with the necessary adaptations.

Les côtés de la première feuille peuvent être rabattus sur la seconde feuille de deux manières : les côtés de la coquille situés de part et d'autre des bandes de déchirement peuvent être rabattus en dernier de manière à être rabattus sur les deux autres côtés ou en premier de manière à être situés sous les deux autres côtés.The sides of the first sheet can be folded on the second sheet in two ways: the sides of the shell located on either side of the tear strips can be folded last so as to be folded on the other two sides or first to be under the other two sides.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention.

  • La figure 1 représente la première feuille découpée avant pliage.
  • La figure 2 représente la première feuille formée en coquille prête à recevoir le produit à conditionner.
  • La figure 3 représente l'emballage terminé selon un premier mode de pliage.
  • La figure 4 représente l'emballage terminé selon un second mode de pliage.
The appended drawing represents, by way of example, an embodiment of the invention.
  • The figure 1 represents the first sheet cut before folding.
  • The figure 2 is the first shell-shaped sheet ready to receive the product to be packaged.
  • The figure 3 represents the finished package according to a first mode of folding.
  • The figure 4 represents the finished package according to a second folding mode.

La figure 1 représente une feuille 1 en polypropylène (PP) découpée en forme d'octogone quasi régulier dont l'un des côtés présente en son milieu une saillie de forme triangulaire dont les côtés sont prolongés par deux entailles 3 et 4 à l'intérieur de la surface octogonale, ces entailles formant dés amorces de déchirure. Deux bandes de déchirement 5 et 6 en PET, préalablement découpées, sont fixées par thermosoudage sur la feuillé 1 de telle manière que les parties coudées 5a et 6a de ces bandes se rejoignent sur la saillie triangulaire 2. Les deux bandes de déchirement 5 et 6 forment ainsi un U pointu dont la pointe coïncide approximativement avec la saille triangulaire 2. Au lieu de deux bandes 5 et 6, on pourrait bien entendu utiliser une seule bande découpée en U.The figure 1 is a sheet 1 of polypropylene (PP) cut in the form of an octagon almost regular whose one side has in its middle a triangular projection whose sides are extended by two notches 3 and 4 inside the surface octagonal, these cuts forming tear primers. Two strips of tear 5 and 6 in PET, previously cut, are fixed by heat sealing on the leaf 1 so that the bent portions 5a and 6a of these strips meet on the triangular projection 2. The two tear strips 5 and 6 thus form a pointed U whose point coincides approximately with the triangular seam 2. Instead of two strips 5 and 6, one could of course use a single U-shaped strip.

Au moyen d'un mandrin et de poussoirs, tels que décrits par exemple dans le brevet CH 690 996 , on donne à la feuille 1 la forme parallélépipédique rectangulaire représentée à la figure 2. Les lignes de pliage principales sont représentées en traits fins à la figure 1. Ces lignes de pliage forment les faces latérales A, B, C et D de la coquille. Pour former les arêtes verticales de la coquille, on plie en outre les parties de la feuille 1 situées entre les faces A, B, C et D selon les lignes de pliage 7 en traits mixtes qui sont perpendiculaires aux côtés correspondants de l'octogone. Le pliage selon 7 et le rabattement contre les faces A et C forment les parties rabattues E, F, G, H représentées à la figure 2. Cette mise en forme de coquille est effectuée par emboutissage dans un couloir emboutisseur chauffant pour maintenir les plis. Les parties rabattues et superposées sont thermosoudées.By means of a chuck and pushers, as described for example in the patent CH 690 996 , sheet 1 is given the rectangular parallelepipedal shape shown in FIG. figure 2 . The main fold lines are represented in fine lines at the figure 1 . These fold lines form the lateral faces A, B, C and D of the shell. To form the vertical edges of the shell, the parts of the sheet 1 located between the faces A, B, C and D along the fold lines 7 in phantom which are perpendicular to the corresponding sides of the octagon. The folding according to 7 and the folding against the faces A and C form the folded portions E, F, G, H shown in FIG. figure 2 . This shell shaping is performed by stamping in a heating stamping duct to maintain the folds. The folded and superimposed parts are heat sealed.

La coquille, telle que représentée à la figure 2, reçoit ensuite le produit à conditionner, dûment dosé. La coquille n'est ainsi remplie qu'environ aux 2/3 de sa hauteur.The shell, as represented in figure 2 then receives the product to be packaged, duly dosed. The shell is thus filled only about 2/3 of its height.

On pose ensuite sur le produit une feuille 8 en PP de forme rectangulaire ou carrée, selon le mode de pliage utilisé.The product is then placed on a sheet 8 of PP of rectangular or square shape, depending on the folding mode used.

Selon le premier mode de pliage représenté à la figure 3, la seconde feuille 8 est rectangulaire. Parallèlement aux bandes de déchirement 5 et 6, sa largeur est égale à celle du fond de la coquille, sa longueur étant donc supérieure à la longueur des côtés du fond de manière à remonter sur les faces A et C, ceci pour améliorer l'étanchéité. Après avoir disposé la feuille 8, on rabat tout d'abord la partie des faces B et D située au dessus de la feuille 8, sur la feuille 8, puis on rabat ensuite les deux autres faces A et C. Les parties rabattues I et J sont ainsi au dessus des parties rabattues K et L. Lors de ce rabattement, la dimension de la saillie triangulaire 2 est telle que ses côtés sont situés dans le prolongement des côtés à 45° des parties rabattues I et J.According to the first folding mode shown in figure 3 the second sheet 8 is rectangular. Alongside the tear strips 5 and 6, its width is equal to that of the bottom of the shell, its length being greater than the length of the sides of the bottom so as to go up on the sides A and C, this to improve the seal . After arranging the sheet 8, the part of the faces B and D situated above the sheet 8 is first folded onto the sheet 8, then the other two faces A and C are folded down. The folded parts I and J are thus above the folded portions K and L. During this folding, the dimension of the triangular projection 2 is such that its sides are located in the extension of the 45 ° sides of the folded portions I and J.

Il est toutefois possible de plier et de rabattre d'abord les parties I et J et ensuite les parties K et L. On obtient alors l'aspect représenté à la figure 4. Ce pliage nécessite toutefois un pliage supplémentaire à 45° de la partie supérieure des rabats F et H pour dégager le passage des bandes de déchirement 5 et 6.However, it is possible to fold and fold parts I and J and then parts K and L first. This gives the appearance shown in FIG. figure 4 . This folding however requires an additional folding at 45 ° of the upper part of the flaps F and H to clear the passage of the tear strips 5 and 6.

Les pliages se font à l'aide d'outils chauffants pour maintenir les plis. La coquille et la feuille de couverture 8 sont ensuite thermoscellées au moyen d'une presse chauffante. Des rabatteurs sous presse assurent que les deux rabats du dernier pliage sont à plat pour éviter qu'ils ne se déplient sous l'effet de la chaleur du fromage, en raison de la mémoire du film de polypropylene.Folding is done with heating tools to maintain the folds. The shell and the cover sheet 8 are then heat-sealed by means of a heating press. Pressing pressers ensure that the two flaps of the last fold are flat to prevent them from unfolding under the heat of the cheese, due to the memory of the polypropylene film.

Lors de ce scellage, au moins l'extrémité de la saillie triangulaire 2 est laissée libre de manière à constituer un coin de préhension pour l'ouverture de l'emballage.During this sealing, at least the end of the triangular projection 2 is left free so as to form a gripping wedge for the opening of the package.

Le film utilisé peut être aussi bien en OPP qu'en PP.The film used can be both OPP and PP.
