Abstract
Description
La présente invention concerne un procédé pour obturer de manière inviolable l'ouverture d'un récipient, notamment un récipient alimentaire, au moyen d'un opercule en aluminium ou autre qui est thermo-scellé sur un élément en matière plastique formant ladite ouverture. The present invention relates to a method for inviolably closing the opening of a container, in particular a food container, by means of an aluminum cover or the like which is heat-sealed on a plastic element forming said opening.
L'obturation d'un récipient au moyen d'un opercule en aluminium thermo-scellé est notamment utilisée sur certains types de conteneurs en matière plastique destinés à recevoir des boissons alcoolisées. Dans ce cas, l'opercule porte également la fiscalité correspondante et il est donc important que cet opercule ne puisse absolument pas être récupéré pour être réutilisé sur un autre conteneur. The closure of a container by means of a heat-sealed aluminum cover is used in particular on certain types of plastic containers intended to receive alcoholic beverages. In this case, the lid also carries the corresponding taxation and it is therefore important that this lid cannot absolutely be recovered to be reused on another container.
A cet effet, le procédé selon l'invention est essentiellement caractérisé en ce qu'il consiste à écraser à chaud par dessus l'opercule, des picots traversant ledit opercule prévus sur la périphérie de l'ouverture à obturer. To this end, the method according to the invention is essentially characterized in that it consists in hot pressing over the cover, spikes passing through said cover provided on the periphery of the opening to be closed.
On obtient ainsi un véritable "rivetage" entraînant imrrédiatement la destruction de l'opercule en cas de tentative de retrait. A real "riveting" is thus obtained, immediately causing the destruction of the cover in the event of an attempted withdrawal.
De préférence, l'opercule, préalablement revêtu d'un vernis thermocollant, est d'abord appliqué sur l'ouverture de manière a être perforé par les picots prévus sur la périphérie de ladite ouverture, puis chauffé afin de faire fondre le vernis thermo-collant, avant que les picots ne soient écrasés à chaud par dessus. Preferably, the cover, previously coated with a fusible varnish, is first applied to the opening so as to be perforated by the pins provided on the periphery of said opening, then heated in order to melt the thermo varnish. sticky, before the pins are crushed hot on top.
Une forme d'exécution de l'invention est décrite ci-après à titre d'exemple, en référence au dessin annexé dans lequel
- la figure 1 est une vue en perspective d'un bouchon de conteneur obturé conformément a la présente invention
- la figure 2 est une vue de dessous de ce bouchon ; et
- la figure 3 est une vue en coupe suivant la ligne III-III de la figure 2.An embodiment of the invention is described below by way of example, with reference to the accompanying drawing in which
- Figure 1 is a perspective view of a closed container cap according to the present invention
- Figure 2 is a bottom view of this plug; and
- Figure 3 is a sectional view along line III-III of Figure 2.
En se référant tout d'abord à la figure 1, on peut voir un bouchon 1 en matière plastique du genre de ceux qui sont utilisés sur certains types particuliers de conteneurs constitués d'une carcasse rigide a l'intérieur de laquelle est placée une enveloppe souple reliée à un robinet qui est disposé dans une cavité ménagée sur ladite carcasse rigide. Ce type de conteneur est notamment destiné à recevoir du vin et la cavité donnant accès au robinet est normalement obturée de manière inviolable au moyen d'un bouchon tel que 1. Referring first to Figure 1, we can see a plastic plug 1 of the kind used in certain particular types of containers made of a rigid carcass inside which is placed an envelope flexible connected to a valve which is disposed in a cavity formed on said rigid carcass. This type of container is in particular intended to receive wine and the cavity giving access to the tap is normally closed in a tamper-proof manner by means of a stopper such as 1.
Ce bouchon est essentiellement constitué par une couronne 2 comportant une jupe latérale 3 et qui est pourvue en son centre d'une ouverture ciculaire 4 obturée au moyen d'un opercule en aluminium 5 thermo-scellé sur la face inferieure de la couronne. La jupe latérale 2 est par ailleurs munie de pattes d'accrochage 6 permettant de fixer le bouchon de manière inamovible sur le conteneur. This stopper is essentially constituted by a crown 2 comprising a lateral skirt 3 and which is provided at its center with a cicular opening 4 closed by means of an aluminum seal 5 heat-sealed on the lower face of the crown. The side skirt 2 is also provided with hooking lugs 6 making it possible to fix the plug irremovably on the container.
Ainsi, pour avoir accès au robinet du conteneur, il est nécessaire de déchirer l'opercule 5 afin d'introduire un doigt à l'intérieur et de tirer ensuite violemment sur le bouchon pour provoquer sa destruction. Cette destruction du bouchon est d'ailleurs facilitée par le fait qu'il comporte un certain nombre d'affaiblissements tels que 7, notamment au niveau de l'angle entre la couronne 2 et la jupe 3. Thus, to have access to the container valve, it is necessary to tear the cover 5 in order to introduce a finger inside and then violently pull on the stopper to cause its destruction. This destruction of the plug is moreover facilitated by the fact that it includes a certain number of weaknesses such as 7, in particular at the level of the angle between the crown 2 and the skirt 3.
Conformément à la présente invention, l'opercule 5 n'est pas seulement fixé de manière classique au moyen d'un vernis thermo-collant sur la face inférieure de la couronne 2. En effet, et ainsi qu'on peut le voir plus clairement sur les figures 2 et 3, un certain nombre de picots 8, prévus sur la péi- phérie de l'ouverture 4 et venus de moulage avec la couronne, sont écrasés à chaud par dessus l'opercule. According to the present invention, the cover 5 is not only fixed in a conventional manner by means of a heat-adhesive varnish on the underside of the crown 2. In fact, and as can be seen more clearly in FIGS. 2 and 3, a certain number of pins 8, provided on the periphery of the opening 4 and coming from molding with the crown, are crushed hot over the cover.
Pour ce faire, on commence par appliquer l'opercule 5 sur l'ouverture 4 au moyen d'un outil approprié, de manière que ledit opercule soit automatiquement perforé par les picots 8 prévus sur la périphérie de l'ouverture. On procède ensuite à un chauffage de l'opercule, afin de faire fondre le vernis thermocollant porté par celui-ci et de provoquer ainsi sa fixation par thermo-scellage sur la couronne 2. Enfin, on applique simultanément sur tous les picots 8 une certaine pression, tout en les chauffant, de manière à provoquer leur écrasement par dessus l'opercule 5. To do this, we begin by applying the cover 5 to the opening 4 using a suitable tool, so that said cover is automatically perforated by the pins 8 provided on the periphery of the opening. Next, the cover is heated, in order to melt the fusible varnish carried by it and thus to cause it to be fixed by heat-sealing on the crown 2. Finally, a certain amount is applied simultaneously to all the pins pressure, while heating them, so as to cause them to be crushed over the cover 5.
L'opercule se trouve ainsi en quelque sorte riveté sur la couronne 2 du bouchon 1 par les picots écrasés 8 et il est alors absolument impossible de le retirer sans le détériorer, ce qui empêche toute réutilisation ultérieure dudit opercule. The cover is thus somehow riveted on the crown 2 of the plug 1 by the crushed pins 8 and it is then absolutely impossible to remove it without damaging it, which prevents any subsequent re-use of said cover.
