Description

L'invention concerne un récipient rigide à vide résiduel avec capsule de fermeture métallique à partie centrale déformable.The invention relates to a rigid residual vacuum container with a metal closure cap with a deformable central part.

Il existe déjà plusieurs systèmes de témoin d'inviolabilité dans le domaine alimentaire, par exemple des systèmes avec une bande de papier collée sur le couvercle de fermeture et le haut du récipient contenant le produit alimentaire. La raison du développement de tels systèmes est la crainte de voir les emballages ouverts par des personnes indélicates, soit pour sciemment y compromettre la stérilité, soit pour y ajouter des produits nocifs à la consommation humaine. La demande de brevet WO-A-9100227, publiée après la date de priorité de la présente demande concerne également un système avec témoin d'inviolabilité, dans lequel il est prévu un cachet positionné à cheval sur la tranche du couvercle et le haut du verre contenant le produit alimentaire. L'inconvénient de ce système est que, lors de l'ouverture, le cachet est cassé et laisse des morceaux multiples qu'il faut prendre garde de jeter rapidement pour qu'ils ne se mélangent pas accidentellement avec le produit alimentaire lui-même. Finalement, la demande de brevet EP-A-0164938 concerne un récipient rigide à vide résiduel avec capsule de fermeture métallique à partie centrale déformable. L'inconvénient de ce système est que la constatation que l'emballage a déjà été ouvert n'est pas suffisamment nette et sûre.There are already several tamper-evident systems in the food sector, for example systems with a strip of paper glued to the closure cover and the top of the container containing the food product. The reason for the development of such systems is the fear of seeing the packages opened by unauthorized people, either to knowingly compromise sterility, or to add products harmful to human consumption. Patent application WO-A-9100227, published after the priority date of the present application also relates to a system with tamper-evident indicator, in which a seal is provided positioned astride the edge of the cover and the top of the glass containing the food product. The disadvantage of this system is that, when opened, the seal is broken and leaves multiple pieces which must be discarded quickly so that they do not accidentally mix with the food product itself. Finally, patent application EP-A-0164938 relates to a rigid container with residual vacuum with a metal closure capsule with a deformable central part. The disadvantage of this system is that the finding that the package has already been opened is not sufficiently clear and secure.

Le récipient, objet de la présente invention, permet de mettre à disposition du consommateur un système d'inviolabilité propre, pratique, d'usage simple et permettant de garantir une sécurité maximale au consommateur.The container, object of the present invention, makes it possible to provide the consumer with a clean, practical inviolability system, of simple use and making it possible to guarantee maximum security for the consumer.

L'invention concerne un récipient rigide à vide résiduel avec capsule de fermeture métallique à partie centrale déformable, comprenant un témoin d'inviolabilité comportant un anneau solidaire de ladite capsule de fermeture et une pastille centrale en une seule partie reliée audit anneau par au moins 2 pattes d'accrochage, la pastille étant située au-dessus de la partie centrale déformable de la capsule de fermeture, ladite pastille se séparant de l'anneau lors de l'ouverture de la capsule de fermeture à cause du soulèvement de la partie centrale déformable.The invention relates to a rigid residual vacuum container with a metal closure cap with a deformable central part, comprising a tamper-evident indicator comprising a ring integral with said closure capsule and a central patch in a single part connected to said ring by at least 2 hooking tabs, the tablet being located above the deformable central part of the closure capsule, said tablet separating from the ring when the closure capsule is opened due to the lifting of the deformable central portion .

Le récipient rigide avec capsule de fermeture métallique à partie centrale déformable est un récipient contenant un produit alimentaire ayant subi une opération engendrant un vide résiduel à l'intérieur dudit récipient. Ce vide résiduel provoque la déformation concave de la partie centrale de la capsule. Le vide résiduel est provoqué par exemple par stérilisation, pasteurisation ou remplissage à chaud. Sous l'effet du refroidissement, une dépression se crée à l'intérieur du récipient, ce qui provoque la déformation concave de la partie centrale dudit récipient. Lorsque le consommateur veut ouvrir le récipient, il dévisse la capsule de fermeture, ce qui remet l'intérieur du récipient à la pression atmosphérique, la partie centrale de ladite capsule se soulève et dégage ainsi la pastille centrale de l'anneau solidaire de la capsule. Il faut bien sûr que les pattes d'accrochage soient suffisamment solides pour ne pas rompre lors de diverses manutentions et suffisamment fines pour que la déformation de la capsule permette une libération totale de la pastille et sa séparation de l'anneau.The rigid container with metal closure cap with deformable central part is a container containing a food product having undergone an operation generating a residual vacuum inside said container. This residual vacuum causes the concave deformation of the central part of the capsule. The residual vacuum is caused for example by sterilization, pasteurization or hot filling. Under the effect of cooling, a vacuum is created inside the container, which causes the concave deformation of the central part of said container. When the consumer wants to open the container, he unscrews the closure capsule, which brings the interior of the container to atmospheric pressure, the central part of said capsule lifts and thus releases the central tablet from the ring secured to the capsule . It is of course necessary that the attachment tabs are strong enough not to break during various handling operations and sufficiently fine for the deformation of the capsule to allow total release of the pellet and its separation from the ring.

Cet anneau est solidaire de la capsule de fermeture par collage. La colle utilisée peut être de tout type connu dans l'état de la technique. La pastille centrale est reliée à l'anneau par trois pattes d'accrochage. Un nombre supérieur de pattes d'accrochages peut cependant aussi être envisagé, par exemple entre 4 et 8. La pastille centrale peut être circulaire mais aussi de toute autre forme, pourvu que sa forme permette la présence de pattes d'accrochage assurant la liaison avec l'anneau.This ring is integral with the closure cap by gluing. The adhesive used can be of any type known in the state of the art. The central patch is connected to the ring by three hooking lugs. A a higher number of latching tabs can however also be envisaged, for example between 4 and 8. The central patch can be circular but also of any other shape, provided that its shape allows the presence of latching tabs ensuring the connection with the 'ring.

Lors de l'ouverture de la capsule de fermeture, pour pouvoir avoir un effet de basculement de la pastille centrale, on prévoit une patte d'accrochage plus solide que les deux autres.When opening the closure capsule, to be able to have a tilting effect on the central patch, a hooking tab is provided which is more solid than the other two.

Pour être bien sûr que la pastille centrale appuie sur la partie centrale de la capsule de fermeture, on prévoie sur ladite pastille centrale du côté en regard de la capsule de fermeture un talon de compensation. Ce talon permet en outre d'économiser de la matière pour la pastille. Le témoin d'inviolabilité est en polystyrène ou toute autre matière plastique cassante. Ce témoin est fabriqué soit par injection, soit par moulage.To be sure that the central patch presses on the central part of the closure capsule, a compensation heel is provided on said central patch on the side opposite the closure capsule. This heel also saves material for the pad. The tamper-evident witness is made of polystyrene or any other brittle plastic material. This control is produced either by injection or by molding.

La suite de la description est faite en référence aux dessins sur lesquels:

  • Fig. 1 est une vue de dessus du récipient avec le système d'inviolabilité selon l'invention et
  • Fig. 2 est une coupe selon la ligne 2-2 de la Fig. 1.
The following description is made with reference to the drawings in which:
  • Fig. 1 is a top view of the container with the tamper-evident system according to the invention and
  • Fig. 2 is a section along line 2-2 of FIG. 1.

Le récipient (6) est fermé par une capsule métallique (5) sur laquelle est collée un témoin d'inviolabilité (1) comportant un anneau (2) et une pastille centrale (3) reliée audit anneau par trois pattes d'accrochage (4). La capsule (5) est vissée sur le bord supérieur du récipient (6) grâce aux bossages (8) et comme le récipient est stérilisé, ladite capsule est bombée vers l'intérieur du récipient. Lorsqu'on ouvre le récipient, la membrane (9) de la capsule (5) exerce une force sur le talon de compensation (7), de sorte que les pattes d'accrochage (4) se cassent, libérant ainsi la pastille centrale (3).The container (6) is closed by a metal capsule (5) on which is glued a tamper-evident indicator (1) comprising a ring (2) and a central patch (3) connected to said ring by three attachment tabs (4 ). The capsule (5) is screwed onto the upper edge of the container (6) thanks to the bosses (8) and as the container is sterilized, said capsule is curved towards the interior of the container. When the container is opened, the membrane (9) of the capsule (5) exerts a force on the compensating heel (7), so that the tabs snap (4) break, thereby releasing the central pad (3).

Il est bien entendu que le témoin d'inviolabilité selon l'invention peut être utilisée avec tout type de récipient comportant une capsule de fermeture ayant une membrane centrale déformable de manière élastique.It is understood that the tamper-evident indicator according to the invention can be used with any type of container comprising a closure capsule having a central membrane which is elastically deformable.
