Description

L'invention concerne un emballage de conditionnement, notamment de produits alimentaires, réalisés en matière plastique selon le préambule de la revendication 1.The invention relates to packaging packaging, especially food products, made of plastic according to the preamble of claim 1.

Un tel emballage est décrit dans le document US-5 511 680.Such a package is described in US-5,511,680.

De tels emballages en matière plastique sont largement connus, notamment pour le conditionnement de produits alimentaires. Parmi ceux-ci, on peut citer un emballage décrit dans le document FR-A-2 707 951.Such plastic packages are widely known, especially for the packaging of food products. Among these, there may be mentioned a package described in document FR-A-2 707 951.

Cet emballage est constitué d'une barquette rigide, qui présente une ouverture délimitée par un rebord périphérique en forme de U inversé, et destiné à recevoir un couvercle comportant un rebord périphérique, de forme complémentaire, donc également en forme de U inversé, destiné à être emboîté, sur le rebord périphérique de la barquette.This package consists of a rigid tray, which has an opening defined by an inverted U-shaped peripheral rim, and intended to receive a lid having a peripheral rim, of complementary shape, thus also inverted U-shaped, intended for be nested on the peripheral edge of the tray.

L'étanchéité entre la barquette et le couvercle est assurée au moyen de deux bandes annulaires, prolongeant les bords périphériques respectifs de la barquette et du couvercle, soudées entre elles sur toute la bordure périphérique externe, et présentant une entaille de déchirure, pour permettre l'ouverture postérieure du couvercle, lors de la première utilisation.The seal between the tray and the lid is provided by means of two annular bands, extending the respective peripheral edges of the tray and lid, welded together over the entire outer peripheral edge, and having a tear notch, to allow posterior opening of the lid, during the first use.

Cependant, un tel couvercle n'assure pas de manière satisfaisante l'obturation du récipient après première utilisation.However, such a lid does not satisfactorily ensure the closure of the container after first use.

On connaît également, de par le document FR-A-2 471 925, un emballage, également en matière plastique, comportant un récipient proprement dit, obturé par un couvercle, avec, comme dans l'exemple précédent, solidarisation par soudage des rebords d'extension et présence d'une zone de moindre résistance du couvercle. De la sorte, et lors de la première utilisation, le couvercle est détaché de son rebord périphérique, puis peut être refermé par emboîtement de celui-ci, au sein du récipient, présentant à cet effet un épaulement coopérant avec un épaulement dont est également muni le couvercle.Document FR-A-2 471 925 also discloses a packaging, also made of plastics material, comprising a receptacle proper, closed off by a lid, with, as in the preceding example, joining by welding of the flanges extension and presence of a zone of least resistance of the lid. In this way, and during the first use, the cover is detached from its peripheral rim, and can be closed by nesting thereof, within the container, having for this purpose a shoulder cooperating with a shoulder which is also provided lid.

Outre le fait que l'outil de fabrication d'un tel couvercle est relativement onéreux, de par la complexité de son architecture, ledit couvercle, après première utilisation devient indépendant du récipient, ce qui s'avère peu commode à l'usage.In addition to the fact that the tool for manufacturing such a cover is relatively expensive, because of the complexity of its architecture, said cover, after first use becomes independent of the container, which is inconvenient to use.

L'invention propose un emballage du type en question, permettant tout d'abord d'optimiser son étanchéité avant utilisation, notamment au gaz, de telle sorte à pouvoir augmenter la date limite de conservation de manière significative. Corollairement, l'emballage conforme à l'invention, vise à optimiser l'inviolabilité, de manière bien apparente, et en outre, permet d'être moulé en une seule étape.The invention proposes a packaging of the type in question, allowing first of all to optimize its tightness before use, in particular with gas, so as to be able to increase the conservation deadline significantly. As a corollary, the packaging according to the invention aims to optimize the inviolability, quite clearly, and moreover, allows to be molded in a single step.

Cet objectif est réalisé en séparant les fonctions d'étanchéité et d'ouverture proprement dite.This objective is achieved by separating the functions of sealing and opening proper.

Cet emballage de conditionnement en matière plastique, constitué d'un récipient fermé par un couvercle, dans lequel :

  • le récipient présente une ouverture délimitée par un rebord périphérique à section en forme de U inversé, formé de deux branches respectivement interne prolongeant la paroi latérale du récipient, et externe ;
  • le couvercle comporte :
    • . un rebord périphérique, également à section en forme de U, de forme complémentaire au rebord périphérique du récipient, destiné à être emboîté sur le rebord dudit récipient, et à être solidarisé à celui-ci par collage ou soudage ;
    • . un disque formant couvercle proprement dit, muni d'un organe de préhension positionné sensiblement à sa périphérie ;
    • . une ligne de moindre résistance, s'étendant au niveau du rebord périphérique du couvercle.
Il se caractérise, en ce que la ligne de moindre résistance présente une discontinuité au niveau de laquelle elle s'étend localement en direction du centre du disque au voisinage de l'organe de préhension.This packaging of plastics material, consisting of a container closed by a lid, in which:
  • the container has an opening defined by an inverted U-shaped peripheral rim, formed of two respectively internal branches extending the side wall of the container, and external;
  • the lid comprises:
    • . a peripheral rim, also of U-shaped section, of complementary shape to the peripheral rim of the container, intended to be fitted on the rim of said container, and to be secured thereto by gluing or welding;
    • . a lid disc proper, provided with a gripping member positioned substantially at its periphery;
    • . a line of weakness, extending at the peripheral edge of the cover.
It is characterized in that the line of least resistance has a discontinuity at which it extends locally towards the center of the disc in the vicinity of the gripping member.

En outre, selon une caractéristique avantageuse de l'invention, le bord périphérique du disque est muni d'une nervure radiale s'étendant entre le lieu d'implantation de l'organe de préhension et le rebord périphérique du couvercle.In addition, according to an advantageous characteristic of the invention, the peripheral edge of the disc is provided with a radial rib extending between the location of implantation of the gripping member and the peripheral rim of the cover.

La mise en oeuvre d'une telle configuration, doublée en outre par la présence de la nervure radiale permet de concentrer la force transmise par l'organe de préhension, lors de la première ouverture, en un lieu déterminé et focalisé de la ligne de moindre résistance, permettant ainsi de prévoir une telle ligne de moindre résistance de plus grande épaisseur, et par voie de conséquence, de disposer d'une grande tolérance, favorisant la fabrication du couvercle.The implementation of such a configuration, further doubled by the presence of the radial rib makes it possible to concentrate the force transmitted by the gripping member, during the first opening, in a specific and focused location of the line of lesser resistance, thus making it possible to provide such a line of least resistance of greater thickness, and consequently, to have a high tolerance, favoring the manufacture of the lid.

En outre, de par la plus grande épaisseur de la ligne de moindre résistance, on dispose d'un effet charnière, que l'on peut localiser de manière diamétralement opposée par rapport au lieu d'implantation de l'organe de préhension, permettant une multiple réutilisation du disque faisant fonction de couvercle, et ainsi conserver plus longtemps les aliments contenus dans le récipient.In addition, due to the greater thickness of the line of least resistance, there is a hinge effect, which can be located in a diametrically opposite manner with respect to the location of the gripping member, allowing multiple reuse of the disc acting lid, and thus longer preserve the food contained in the container.

Ainsi, l'invention vise à bien scinder les fonctions de fixation, par soudure ou collage, du couvercle sur le récipient, et d'ouverture dudit récipient. En effet, ce n'est pas à proprement parler le couvercle qui est ouvert, dans la mesure où son rebord périphérique demeure en permanence collé ou soudé sur le rebord périphérique du récipient, mais le disque d'obturation central qui est susceptible d'être ouvert. Ce faisant, on optimise de manière importante l'étanchéité du contenu dudit récipient, notamment par rapport aux récipients de l'art antérieur. En outre, on dispose d'une pièce unique, dans laquelle ledit disque n'est pas désolidarisé de l'ensemble constituant couvercle et récipient.Thus, the invention aims to divide the fixing functions, by welding or gluing, the lid on the container, and opening said container. Indeed, it is not strictly speaking the lid that is open, insofar as its peripheral rim remains permanently glued or welded on the peripheral rim of the container, but the central obturating disk which is likely to be open. In doing so, the sealing of the contents of said container is particularly optimized, particularly with respect to the containers of the prior art. In addition, there is a single piece, wherein said disc is not detached from the lid and container assembly.

Dans une première forme de réalisation de l'invention, cette ligne de moindre résistance est quasi-continue et présente des interruptions propres à constituer des charnières d'articulation du disque sur le rebord périphérique du couvercle.In a first embodiment of the invention, this line of least resistance is quasi-continuous and has interruptions capable of constituting articulation hinges of the disc on the peripheral rim of the cover.

Dans une autre forme de réalisation de l'invention, cette ligne de moindre résistance est en fait constituée par une succession de points d'attache ou picots, solidarisant à intervalles réguliers les deux parties de la portion plane du rebord périphérique du couvercle, les zones de ladite portion plane du couvercle s'étendant entre les points d'attache ou picots étant exemptes de toute matière.In another embodiment of the invention, this line of least resistance is in fact constituted by a succession of attachment points or pins, solidarisant at regular intervals the two parts of the flat portion of the peripheral rim of the cover, the zones said flat portion of the cover extending between the attachment points or pins being free of any material.

On a donc représenté en relation avec les figures 1 et 2, une forme de réalisation de l'emballage de conditionnement conforme à l'invention.FIGS. 1 and 2 show an embodiment of the packaging package according to the invention.

Dans la description qui suit, cet emballage est plus particulièrement destiné à recevoir un produit alimentaire frais, du type salade etc...In the following description, this package is more particularly intended to receive a fresh food product, salad type etc ...

Fondamentalement, celui-ci comporte un récipient de forme arrondie (1), dans l'exemple décrit, de symétrie de révolution, présentant une ouverture supérieure (6), destinée à être obturée par un couvercle (2).Basically, it comprises a rounded container (1), in the example described, of symmetry of revolution, having an upper opening (6) intended to be closed by a cover (2).

Le rebord supérieur du récipient (1) présente une section en forme de U inversé, tel qu'on peut l'observer au sein des figures 12 et 13.The upper rim of the container (1) has an inverted U-shaped section, as can be seen in Figures 12 and 13.

Plus précisément, cette disposition particulière comporte une branche interne (7), une branche externe (8), les deux branches étant reliées entre elles par une portion sensiblement horizontale (9).More specifically, this particular arrangement comprises an inner branch (7), an outer branch (8), the two branches being interconnected by a substantially horizontal portion (9).

La branche interne (7) prolonge en fait la paroi latérale du récipient (1), l'ensemble étant issu du moulage, notamment par injection.The inner branch (7) in fact extends the side wall of the container (1), the assembly being derived from the molding, in particular by injection.

Le couvercle (2) est constitué d'un rebord périphérique (3), destiné à venir s'emboîter sur le rebord périphérique du récipient (1), et comporte en outre un disque (4) obturant l'ouverture (6) du récipient (1). Le disque (2) est muni, au voisinage de sa périphérie, d'un organe de préhension (5), constitué dans le cas d'espèce d'un anneau sensiblement circulaire, dont les deux extrémités sont solidarisés sur la base du disque d'obturation (4) au voisinage du bord périphérique (3) du couvercle (2).,.
Selon cette forme de réalisation, l'anneau de préhension est systématiquement orienté selon un plan parallèle au disque (4), sauf lors des phases d'ouverture. Il revient après de telles phases à sa position naturelle dans ledit plan parallèle au disque (4), de par l'effet élastique de la matière plastique qui le constitue.The lid (2) consists of a peripheral flange (3) designed to fit on the peripheral rim of the container (1), and further comprises a disc (4) closing the opening (6) of the container (1). The disc (2) is provided, in the vicinity of its periphery, with a gripping member (5), constituted in this particular case by a substantially circular ring, the two ends of which are secured to the base of the disc. closing (4) in the vicinity of the peripheral edge (3) of the cover (2).
According to this embodiment, the gripping ring is systematically oriented in a plane parallel to the disk (4), except during the opening phases. It returns after such phases to its natural position in said plane parallel to the disc (4), due to the elastic effect of the plastic material that constitutes it.

On a décrit en relation avec les figures 3 à 6, une première forme de réalisation du couvercle (2) conforme à l'invention. Le couvercle, selon cette première forme de réalisation, présente donc un rebord (3) faisant saillie par rapport au plan général du disque (4) (voir figures 4 et 5).With reference to FIGS. 3 to 6, a first embodiment of the lid (2) according to the invention has been described. The lid, according to this first embodiment, therefore has a flange (3) projecting from the general plane of the disc (4) (see Figures 4 and 5).

Le rebord périphérique (3) du couvercle (2) est également en section en forme de U inversé, de telle sorte à pouvoir s'emboîter sur le rebord périphérique du récipient (1), ainsi qu'on peut bien l'observer sur les figures 12 et 13.The peripheral rim (3) of the lid (2) is also in inverted U-shaped section, so that it can fit on the peripheral rim of the container (1), as can be seen on the Figures 12 and 13.

Il est constitué :

  • . d'une branche interne (15), s'étendant à partir du disque (4) et destinée à venir en contact avec la branche interne (7) du rebord périphérique du récipient (1),
  • . d'une branche externe (16) destinée à venir coopérer avec la branche externe (8) du récipient (1),
  • . et d'une partie plane (17) reliant de manière continue ou discontinue, lesdites branches interne et externe (15) et (16).
It consists :
  • . an inner branch (15) extending from the disc (4) and intended to come into contact with the inner branch (7) of the peripheral rim of the container (1),
  • . an external branch (16) intended to cooperate with the outer branch (8) of the container (1),
  • . and a flat portion (17) connecting in a continuous or discontinuous manner, said inner and outer legs (15) and (16).

Avantageusement, la branche externe (16) du rebord périphérique (3) du couvercle (2) est munie d'une saillie (18) dirigée vers l'intérieur, destinée à favoriser la coopération entre la branche externe (16) du couvercle (2) et l'extrémité inférieure de la branche externe (8) du récipient (1).Advantageously, the outer branch (16) of the peripheral rim (3) of the cover (2) is provided with an inwardly directed projection (18) intended to promote cooperation between the outer branch (16) of the cover (2). ) and the lower end of the outer leg (8) of the container (1).

Selon l'invention, la partie plane (17) du rebord périphérique (3) du couvercle (2) présente une zone de moindre résistance (10), sensiblement circulaire.According to the invention, the flat portion (17) of the peripheral rim (3) of the cover (2) has a zone of least resistance (10), substantially circular.

Cette zone de moindre résistance est obtenue par réduction de la quantité de matière à ce niveau, ainsi qu'on peut bien l'observer, notamment sur la figure 6, ou la figure 12.This zone of least resistance is obtained by reducing the quantity of material at this level, as can be clearly seen, particularly in FIG. 6 or FIG.

Cette ligne de moindre résistance (10) est sensiblement continue, sauf au niveau de deux zones (11), sensiblement diamétralement opposée à la zone d'implantation de l'anneau de préhension (5).This line of least resistance (10) is substantially continuous, except at two zones (11), substantially diametrically opposite the implantation zone of the gripping ring (5).

Ces zones (11) sont destinées à constituer charnières lors de l'ouverture du disque (4).These zones (11) are intended to form hinges during the opening of the disk (4).

Corollairement et selon l'invention, la zone du rebord périphérique située à l'aplomb de l'anneau de préhension (5) présente une discontinuité constituée d'un bec (12), orientée au direction du centre du disque (4), et destinée à favoriser l'amorce de rupture de la ligne de moindre résistance (10).As a corollary and according to the invention, the area of the peripheral rim located vertically above the gripping ring (5) has a discontinuity consisting of a spout (12) oriented towards the center of the disc (4), and intended to promote the initiation of breakage of the line of least resistance (10).

En outre et selon une caractéristique de l'invention, le rebord périphérique se prolonge au niveau du bec (12) par une nervure (13), radiale, s'étendant sensiblement sur toute la hauteur du rebord périphérique, ainsi qu'on peut l'observer, notamment figures 5 et 6. Cette nervure constitue en quelque sorte une extension du bec (12).In addition and according to a characteristic of the invention, the peripheral rim extends at the spout (12) by a rib (13), radial, extending substantially over the entire height of the peripheral rim, so that Observe, particularly Figures 5 and 6. This rib is a kind of extension of the beak (12).

Ce faisant, la nervure aboutit sensiblement sur le disque entre les deux zones d'implantation des extrémités de l'anneau de préhension (5) sur le disque (4) (voir figures 5 et 11).In doing so, the rib ends substantially on the disk between the two zones of implantation of the ends of the gripping ring (5) on the disk (4) (see FIGS. 5 and 11).

Cette nervure a pour objet de concentrer l'effort de traction exercé par l'anneau de préhension (5) au niveau du bec (12), et partant favoriser la rupture de la ligne de moindre résistance (10).This rib is intended to concentrate the tensile force exerted by the gripping ring (5) at the nozzle (12), and thereby promote the breaking of the line of weakness (10).

De par la concentration de l'effort de traction, il devient possible d'augmenter l'épaisseur effective de la ligne de moindre résistance (10), se traduisant par un double effet.By concentrating the tensile force, it becomes possible to increase the effective thickness of the line of least resistance (10), resulting in a double effect.

Tout d'abord, l'effet charnière est augmenté par optimisation de la résistance mécanique d'arrachage du disque hors du rebord périphérique. Il n'est pas rare en effet qu'une traction excessive exercée par l'utilisateur provoque l'arrachement total du disque.Firstly, the hinge effect is increased by optimizing the mechanical resistance of pulling the disc out of the peripheral rim. It is not uncommon indeed that excessive traction exerted by the user causes the total tearing of the disc.

En outre, il permet d'aboutir à une plus grande coopération entre la paroi interne (15) du rebord périphérique (3) du couvercle avec la paroi interne (7) du rebord du récipient, optimisant de fait les conditions de conservation du contenu du récipient, après première ouverture, de par l'étanchéité relative née de cette coopération.In addition, it allows to achieve greater cooperation between the inner wall (15) of the peripheral rim (3) of the lid with the inner wall (7) of the rim of the container, optimizing the conditions of conservation of the contents of the container. container, after first opening, by the relative sealing born of this cooperation.

Dans une autre forme de réalisation représentée en relation avec les figures 7 à 10, la ligne de moindre résistance (10) est remplacée par l'absence de toute matière à ce niveau.
Seuls des picots (19) solidarisent à intervalles réguliers les portions de la partie plane (17) du rebord périphérique du couvercle (2). L'effet charnière est maintenu de par la présente de picots, en des lieux appropriés, toujours en position sensiblement diamétralement opposée par rapport à l'anneau de préhension (5), et le principe de la nervure demeure également identique.In another embodiment shown in connection with FIGS. 7 to 10, the line of least resistance (10) is replaced by the absence of any material at this level.
Only pins (19) solidarize at regular intervals the portions of the flat portion (17) the peripheral rim of the lid (2). The hinge effect is maintained here by pins, in appropriate places, always in substantially diametrically opposite position with respect to the gripping ring (5), and the principle of the rib also remains the same.

Alors que la première forme de réalisation est plus particulièrement approprié dans le cadre d'une fixation par soudage du rebord périphérique (3) du couvercle (2) sur le rebord périphérique du récipient (1), la seconde forme de réalisation est tout particulièrement mise en oeuvre dans le cadre d'une solidarisation par collage.While the first embodiment is more particularly suitable in the context of a welding attachment of the peripheral rim (3) of the cover (2) on the peripheral rim of the container (1), the second embodiment is particularly suitable. implemented in the context of a joining by bonding.

Dans le première cas, le soudage par ultrasons notamment, intervient sensiblement selon une portion annulaire (20) externe par rapport à la partie respectivement (9) et (17) des rebords périphériques du récipient (1) et du couvercle (2).In the first case, the ultrasonic welding in particular, occurs substantially in an annular portion (20) external to the portion respectively (9) and (17) peripheral rims of the container (1) and the lid (2).

En revanche, le collage (21) s'effectue sensiblement sur toute la partie plane, tel qu'on peut l'observer sur la figure 13.On the other hand, the bonding (21) takes place substantially over the entire flat part, as can be seen in FIG. 13.

Ce mode de solidarisation permet de conférer au contenu du récipient une parfaite étanchéité, y compris au gaz, pendant une période déterminée, ce qui constitue l'un des buts recherchés par la présente invention.This method of joining allows to confer the contents of the container a perfect seal, including gas, for a period determined, which is one of the aims of the present invention.

Selon l'invention, l'ensemble constitué par le couvercle (2), le disque d'obturation (4) et l'organe de préhension (5) est monobloc et directement obtenu de moulage par injection.According to the invention, the assembly consisting of the cover (2), the sealing disc (4) and the gripping member (5) is monobloc and directly obtained by injection molding.

Le système de fixation mis en oeuvre et en outre le principe de la zone de moindre résistance confèrent en outre l'inviolabilité au récipient.The fastening system used and in addition the principle of the area of least resistance further confer inviolability to the container.

En effet, si celui-ci a été ouvert une première fois, cela apparaît de manière évidente et immédiate à l'acquéreur potentiel dudit récipient.Indeed, if it has been opened a first time, it appears obvious and immediate to the potential purchaser of said container.

Par ailleurs, de par le système de fermeture mis en oeuvre, l'ouverture du récipient est très aisé par l'utilisateur, et s'effectue en une seule opération.Moreover, by the closure system implemented, the opening of the container is very easy by the user, and is carried out in a single operation.

Selon une variante de l'invention représentée en relation avec les figures 14 à 16, l'anneau de préhension (5) n'est pas solidarisé sur la base du disque (4), mais au niveau supérieur de son rebord périphérique, dans une zone immédiatement adjacente au bec (12). Cette forme de réalisation permet d'éviter la mise en oeuvre de la nervure radiale (13), et donc simplifie la réalisation de l'emballage de l'invention.According to a variant of the invention shown in relation to FIGS. 14 to 16, the gripping ring (5) is not secured to the base of the disc (4), but at the upper level of its peripheral rim, in a immediately adjacent to the spout (12). This embodiment avoids the implementation of the radial rib (13), and therefore simplifies the realization of the packaging of the invention.

En outre, cet anneau peut être conformé de telle sorte à s'étendre selon deux plans concourants, ainsi qu'on peut bien l'observer au sein des figures 15 et 16, susceptible ainsi de permettre son rabattement sur le fond du disque (4), et corollairement, à favoriser l'empilage des emballages conformes à l'invention les uns sur les autres.In addition, this ring may be shaped so as to extend in two concurrent planes, as can be seen in FIGS. 15 and 16, thus allowing it to be folded onto the bottom of the disc (4). ) and, as a corollary, to favor the stacking of the packs according to the invention on top of one another.

Afin d'ouvrir ledit emballage, il convient tout d'abord de tirer la languette de l'anneau vers le haut, libérant alors le passage du doigt dont il est muni, et alors procéder à une traction, dont les efforts se concentrent au niveau du bec (12).In order to open said package, it is first necessary to pull the tongue of the ring upwards, releasing the passage of the finger with which it is provided, and then proceed to a pull, whose efforts are concentrated at spout (12).

Il peut être observé que par la mise en oeuvre du système de fermeture de l'invention, on évite la mise en place de tout système d'operculage, qui, s'il est certes garant d'une étanchéité satisfaisante, en revanche engendre des surcoûts non négligeables, tant lors de la fabrication de l'emballage que lors de son remplissage et de sa fermeture.It can be observed that by the implementation of the closure system of the invention, it avoids the establishment of any sealing system, which, although it ensures a satisfactory seal, on the other hand generates significant additional costs, both during the manufacture of the packaging and during its filling and closure.

On conçoit de fait tout l'intérêt de la présente invention dans le cadre du stockage et de la conservation de produits alimentaires dans des récipients, notamment pour des produits dits « fraîcheurs ».It is conceivable in fact all the advantages of the present invention in the context of storage and preservation of food products in containers, especially for products known as "fresh".

En outre, l'emballage de l'invention se présente sous une seule pièce, remplissant les différentes fonctions qui lui sont dévolues, et notamment la fermeture étanche, et les différentes opérations d'ouverture et de fermeture consécutives après première utilisation.In addition, the packaging of the invention is in one piece, fulfilling the various functions assigned to it, and in particular the sealing, and the various operations of opening and closing after consecutive first use.
