Abstract

The container has a flat annular opening edge (2) provided with an externally curved peripheral part (3). The container is fabricated by thermomolding with preconditioned blank of the flat annular edge and consecutive bending of the curved peripheral part or still fabricated by injection. The curved part is perfectly held to the container by the bottom of its edge during filling or sealing.

Description

La présente invention concerne le domaine de la fabrication de récipients légers en matière synthétique destinés à la présentation et à la vente de produits alimentaires, tels que des boissons, des laitages ou autres, et a pour objet un récipient à bord thermoscellable et bordelé.The present invention relates to the field of the manufacture of lightweight containers of synthetic material intended for presentation and sale of food products, such as beverages, dairy products or others, and relates to a container with heat-sealable and bordered edge.

Il existe actuellement différents types de récipients, qui sont généralement affectés à une utilisation bien particulière, à savoir soit à la présentation et à la vente de produits qui sont enfermés dans lesdits récipients par un opercule thermoscellable, lesdits produits étant versés dans un autre récipient en vue de leur dégustation sous forme de boissons ou d'aliments pâteux, soit à servir comme récipient de dégustation sous forme de gobelet de réception d'une boisson.There are currently different types of containers, which are usually assigned to a particular use, namely either at the presentation and sale of products which are enclosed in the said containers by a heat-sealable seal, said products being paid in another container for their tasting in the form of drinks pastries or to serve as a tasting container under cup shape for receiving a drink.

Les récipients en forme de gobelets sont obtenus par thermoformage et munis d'un bord d'ouverture bordelé, c'est-à-dire qui est découpé après thermoformage et dont la lisière est rabattue à chaud ou roulée en direction de la paroi extérieure correspondante.The cup-shaped containers are obtained by thermoforming and provided with a bordered opening edge, that is to say which is cut after thermoforming and whose edge is folded when hot or rolled towards the corresponding outer wall.

Le bord ainsi obtenu présente le plus souvent une section transversale sensiblement arrondie mais relativement irrégulière, de sorte qu'il ne peut pas permettre la fixation par thermoscellage d'un opercule de fermeture étanche.The edge thus obtained presents most often a section transversely rounded but relatively irregular, so that it can not allow the fixation by heat-sealing of a lid of waterproof closure.

Un tel thermoscellage nécessite une parfaite régularité du bord du récipient devant être pourvu d'un opercule, ce qui ne peut être assuré par le mode de réalisation actuel de ces gobelets. Ces derniers peuvent, effectivement, présenter des hauteurs de la partie bordelée variables en fonction des déformations réalisées après la découpe du bord d'ouverture après le thermoformage, de sorte que les différentes opérations de remplissage, effectuées pour des récipients destinés à la présentation et à la vente, ne peuvent être réalisées de manière fiable et qu'un scellage parfait ne peut être assuré.Such heat sealing requires a perfect regularity of the edge the container to be provided with a lid, which can not be ensured by the current embodiment of these cups. These can, actually, present heights of the bordered variable part in function of the deformations carried out after the cutting of the opening edge after thermoforming, so that the different operations of filling, carried out for containers intended for presentation and sale, can not be carried out reliably and that a perfect seal can not be insured.

Les récipients pouvant être pourvus d'un opercule thermoscellé se présentent sous forme de pots munis d'un bord annulaire plat obtenu par découpe après thermoformage. Ces récipients, qui sont parfaitement adaptés, du fait même du procédé de réalisation de leur bord, à la réception d'un opercule thermoscellable ne peuvent, cependant, pas être utilisés comme récipients pour une consommation directe, par exemple en portant le bord de ce récipient aux lèvres. En effet, il y a dans un tel cas, pour le moins, un contact désagréable pour l'utilisateur, voire un risque de blessure des lèvres, qui est dû à la coupe franche réalisée à la lisière du bord annulaire, coupe qui a pour effet de rendre ce bord relativement tranchant, voire de faire apparaítre à la base de ce bord, qui arrive en contact direct avec les lèvres, des bavures formant autant d'aspérités coupantes.Containers that can be equipped with a heat seal are in the form of pots with a flat annular edge obtained by cutting after thermoforming. These containers, which are perfectly adapted, by the very fact of the process of producing their edge, at the reception of a heat-sealable seal can not, however, be used as containers for direct consumption, for example by wearing the edge of this container to the lips. Indeed, there is in such a case, for the less, an unpleasant contact for the user, even a risk of injury of the lips, which is due to the clean cut made at the edge of the edge annular, cutting which has the effect of making this edge relatively sharp, even to show up at the base of this edge, which comes into direct contact with the lips, burrs forming so many sharp asperities.

La présente invention a pour but de pallier ces inconvénients en proposant un récipient à bord thermoscellable et bordelé, permettant son utilisation aussi bien comme récipient de présentation et de vente que comme récipient destiné à la dégustation.The present invention aims to overcome these disadvantages by proposing a container with a heat-sealable and bordered edge, allowing its use as well as presentation and sales container that as a container for tasting.

A cet effet, le récipient conforme à l'invention est caractérisé en ce qu'il présente un bord d'ouverture annulaire plat muni d'une partie périphérique externe bordelée.For this purpose, the container according to the invention is characterized in it has a flat annular opening edge with a part external device bordered.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel :

  • la figure 1 est une vue en élévation et en coupe d'un récipient conforme à l'invention et,
  • la figure 2 est une vue partielle en coupe et à plus grande échelle représentant le bord d'ouverture.
    • The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the appended schematic drawing, in which:
  • FIG. 1 is a view in elevation and in section of a container according to the invention and,
  • Figure 2 is a partial sectional view and on a larger scale showing the opening edge.

    • La figure 1 des dessins annexés représente un récipient tel qu'un pot ou un gobelet 1 destiné à la réception de produits pour la vente et la consommation.FIG. 1 of the attached drawings shows a container such a pot or a cup 1 for receiving products for sale and the consumption.

    Conformément à l'invention, ce récipient présente un bord d'ouverture annulaire plat 2 muni d'une partie périphérique externe bordelée 3.According to the invention, this container has an edge flat annular opening 2 having an outer peripheral portion bordelée 3.

    Une telle réalisation du bord d'ouverture annulaire 2 permet d'assurer, d'une part, l'existence d'une surface parfaitement plane pour le thermoscellage d'un opercule et, d'autre part, la présence d'une partie périphérique externe bordelée 3, prolongeant le bord d'ouverture annulaire plat 2, permet un contact agréable lorsque le récipient est porté aux lèvres et sert directement pour la consommation ou la dégustation, ce sans risquer une blessure des lèvres.Such an embodiment of the annular opening edge 2 allows to ensure, on the one hand, the existence of a perfectly flat surface for the heat sealing of a lid and, on the other hand, the presence of a part external peripheral 3, extending the annular opening edge plate 2, allows a pleasant contact when the container is worn on the lips and serves directly for consumption or tasting, without risking an injury to the lips

    En outre, la partie bordelée 3 peut être réalisée avec une grande précision dimensionnelle, de sorte qu'elle permet d'assurer un maintien constant et parfait du récipient par le dessous de son bord lors de son remplissage et lors de l'operculage.In addition, the bordelée part 3 can be realized with a large dimensional accuracy, so that it helps to maintain constant and perfect container from below its edge during its filling and when lidding.

    Cette précision dimensionnelle est très importante, du fait que, généralement, les dispositifs de remplissage des récipients sont appliqués directement sur le bord de l'ouverture de ces derniers et qu'une différence de hauteur desdits bords risquerait de nuire à l'étanchéité lors du remplissage provoquant ainsi, par exemple, des pertes par éclaboussures. De telles pertes par éclaboussures auraient, en outre, l'inconvénient de participer à une pollution des machines de remplissage.This dimensional accuracy is very important, because, generally, the filling devices of the containers are applied directly on the edge of the opening of these and that a difference of height of said edges could affect the sealing during filling thus causing, for example, splash losses. Such Splash losses would, in addition, have the disadvantage of participating in pollution of the filling machines.

    Par ailleurs, un problème analogue pourrait se poser avec les machines de thermoscellage, dont la distance au bord de l'ouverture et/ou la course en vue de l'application d'un opercule sur ce bord, doivent être parfaitement constantes, ce afin de garantir, lors du thermoscellage, une résistance à la pression suffisante pour que ledit thermoscellage soit parfait.In addition, a similar problem could arise with heat sealing machines, the distance to the edge of the opening and / or the run for the application of a seal on this edge, must be perfectly constant, in order to guarantee, during heat sealing, a sufficient pressure resistance for said heat seal to be perfect.

    Le récipient conforme à l'invention peut être réalisé par thermoformage avec découpe préalable d'un bord annulaire plat et roulage consécutif de la partie extérieure bordelée ou encore par injection.The container according to the invention can be produced by thermoforming with preliminary cutting of a flat annular edge and rolling consecutive part of the outer part bordelée or by injection.

    Grâce à l'invention, il est possible de réaliser un récipient pouvant servir simultanément à la présentation et à la vente et comme récipient de dégustation ou de consommation, du fait que ce récipient présente un bord supérieur pouvant recevoir un opercule thermoscellable et que ce bord est muni d'une partie bordelée évitant tout risque de blessure des lèvres lorsque ledit récipient est porté à la bouche.Thanks to the invention, it is possible to produce a container which can be used simultaneously for presentation and sale and as tasting or consumption container, because this container has an upper edge that can receive a heat-sealable seal and that this edge is provided with a bordelée part avoiding any risk of injury lips when said container is brought to the mouth.

    Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the mode of embodiment described and shown in the accompanying drawing. Modifications remain possible, particularly from the point of view of the constitution of the various elements or by substituting technical equivalents, without departing from the field of protection of the invention.
