Description

DISPOSITIF INDICATEUR DE PRESSION, NOTAMMENT POUR UN EMBALLAGE ETANCHE. PRESSURE INDICATOR DEVICE, PARTICULARLY FOR SEALED PACKAGING.
La présente invention est relative à un dispositif in- dicateur de pression de type nouveau, destiné à équiper un emballage étanche.The present invention relates to a pressure indicator device of the new type, intended to equip a sealed package.
Un tel emballage peut concerner en particulier (quoique non exclusivement) des produits alimentaires. Il peut s'agir notamment : - d'une bouteille contenant une boisson gazeuse ou pétillanteSuch packaging may relate in particular (although not exclusively) to food products. It can be in particular: - a bottle containing a carbonated or sparkling drink
- d'une bombe contenant un aérosol (peinture, enduit, produit cosmétiques, etc);- a bomb containing an aerosol (paint, coating, cosmetic product, etc.);
- d'une boîte ou d'un bocal contenant des aliments en conser¬ ve, etc... Dans le cas d'une boîte de conserve, le contenu est nor¬ malement sans pression. Par contre, si une pression apparaît, cela indique généralement que le contenu a fermenté, si bien qu'il est devenu impropre à la consommation. Dans ce cas, l'invention vise à prévenir l'utilisateur de l'apparition de cette pression.- a box or a jar containing canned food, etc ... In the case of a can, the contents are normally without pressure. On the other hand, if a pressure appears, it generally indicates that the content has fermented, so that it has become unfit for consumption. In this case, the invention aims to warn the user of the appearance of this pressure.
D'une manière générale, l'invention concerne un capteur destiné à équiper un bocal, boîtier, ou autres emballages clos, pour avertir un utilisateur extérieur de l'existence ou non d'une pression interne, ou du niveau de cette pression. Un dispositif indicateur .-selon .1 ' invention , destiné à équiper une paroi d'un emballage clos, est caractérisé en ce qu'il comprend en combinaison :In general, the invention relates to a sensor intended to equip a jar, case, or other closed packaging, to warn an external user of the existence or not of an internal pressure, or of the level of this pressure. An indicator device according to the invention, intended to equip a wall with closed packaging, is characterized in that it comprises in combination:
- d'une part au moins une zone transparente de la paroi de l'emballage clos; - d'autre part, appliqué contre la face interne de cette pa¬ roi transparente, un produit d'un type en-lui-même connu dont la couleur visible varie en fonction de la pression à laquelle il est soumis.- on the one hand at least one transparent area of the wall of the closed package; - On the other hand, applied against the internal face of this transparent pa¬ king, a product of a type known per se whose visible color varies according to the pressure to which it is subjected.
Suivant une autre acarctéristique de l'invention, le produit indicateur imprègne une pastille d'une feuille souple qu'on applique contre la face interne de la paroi transparen¬ te .According to another characteristic of the invention, the indicator product impregnates a pellet with a flexible sheet which is applied against the internal face of the transparent wall.
Suivant une autre caractéristique de l'invention, l'em¬ ballage est constitué par une bouteille, un bocal ou une boîte dont la paroi est en un matériau transparent, tel que d verre ou de la matière plastique.According to another characteristic of the invention, the packaging consists of a bottle, a jar or a box, the wall of which is made of a transparent material, such as d glass or plastic.
Suivant une autre caractéristique de l'invention, le dispositif détecteur est incorporé à une capsule de bou- chage, destinée à être vissée ou sertie sur le goulot d'une bouteille ou d'un bocal.According to another characteristic of the invention, the detector device is incorporated in a closure cap, intended to be screwed or crimped onto the neck of a bottle or a jar.
Suivant une autre caractéristique de l'invention, la capsule est en un matériau opaque (métal ou matière plas¬ tique) et elle est découpée suivant une ouverture sous la- quelle est appliqué un opercule transparent dont la face interne porte une pastille imprégnée du produit indicateur de pression.According to another characteristic of the invention, the capsule is made of an opaque material (metal or plas¬ tic material) and it is cut through an opening under which a transparent cover is applied, the inner face of which carries a tablet impregnated with the product. pressure indicator.
Suivant une autre caractéristique de l'invention, l'em¬ pilage de l'opercule transparent et de la pastille impré- gnée est complété par l'application contre ce dernier d'une membrane souple d ' étanchéité.According to another characteristic of the invention, the piling of the transparent cover and of the impregnated tablet is completed by the application against the latter of a flexible waterproofing membrane.
Le dessin annexé donné à titre d'exemple non limitatif, permettra de mieux comprendre l'invention et les avantages qu'elle est susceptible de procurer. Figure 1 montre le goulot d'une bouteille dont la capsu¬ le de bouchage est équipée d'un dispositif indicateur selon 1 ' invention.The appended drawing, given by way of nonlimiting example, will allow a better understanding of the invention and the advantages which it is likely to provide. Figure 1 shows the neck of a bottle whose capsu¬ the corking is equipped with an indicator device 1 according to the invention.
Figure 2 montre une boîte de conserve transparente ainsi équipée. Figure 3 est une vue éclatée montrant en coupe les dif¬ férents éléments superposés d'une capsule de bouchage à vis¬ ser équipée selon l'invention,Figure 2 shows a transparent can thus equipped. FIG. 3 is an exploded view showing in section the various superimposed elements of a screw cap closure cap fitted according to the invention,
Figure 4 est une coupe diamétrale d'une capsule métalli¬ que à sertir, équipée selon l'invention, Figure 5 est une coupe suivant V-V (figure 2) dans le cas d'une boîte ou d'un bocal de conserves.Figure 4 is a diametrical section of a metalli¬ crimping capsule, equipped according to the invention, Figure 5 is a section along V-V (Figure 2) in the case of a can or a jar of preserves.
On a représenté sur la figure 1 une bouteille en verre 1 dont le goulot est refermé de façon étanche par une capsu¬ le métallique sertie 2. Le bouchage de la bouteille 1 pour- rait également être prévu à l'aide d'une capsule vissée 3 du genre illustré sur la figure 3. Cette capsule 3 serait par exemple réalisée en matière plastique. On prévoit au centre une ouverture 4 dans laquelle peut venir s'encastrer le bossage central 5 d'un opercule transparent 6. L'ensemble 5, 6 peut être réalisé par injection en une matière plasti- que transparente.FIG. 1 shows a glass bottle 1, the neck of which is tightly closed by a crimped metal cap 2. The corking of the bottle 1 could also be provided using a screw cap. 3 of the kind illustrated in FIG. 3. This capsule 3 would for example be made of plastic. An opening 4 is provided in the center in which the central boss 5 of a transparent cover 6 can be fitted. The assembly 5, 6 can be produced by injection in a plastic material. that transparent.
Sous l'opercule 6, et contre sa face interne 7, on appli¬ que une pastille souple 8 dont la face supérieure 9 est imprégnée d'un produit indicateur d'un type en lui-même connu : un tel produit a la propriété de changer de cou¬ leur en fonction de la pression environnante à laquelle il est soumis. Ce produit peut imprégner l'ensemble de la substance de la pastille 8, ou bien y être appliqué par impression ou par sérigraphie sur la face 9.Under the cover 6, and against its internal face 7, it is applied that a flexible pad 8 whose upper face 9 is impregnated with an indicator product of a type in itself known: such a product has the property of change color according to the surrounding pressure to which it is subjected. This product can impregnate all of the substance of the patch 8, or else be applied to it by printing or by screen printing on the face 9.
On complète l'empilage en plaçant sous la pastille 8, une membrane souple d'étanchéité 10 d'un type en lui-même connu dans les techniques du bouchage.The stacking is completed by placing under the pellet 8, a flexible sealing membrane 10 of a type in itself known in the sealing techniques.
On a représenté sur la figure 4 un empilage analogue 5, 6, 8, 10 après sa mise en place dans une capsule métalli¬ que 2 du genre de celle qu'on utilise couramment pour re¬ fermer le goulot des bouteilles concernant des boissons gazeuses .FIG. 4 shows a similar stack 5, 6, 8, 10 after it has been put into place in a metalli¬ capsule 2 of the type that is commonly used to close the neck of bottles relating to carbonated drinks. .
Dans l'exemple illustré sur les figures 2 et 5, c'est l'ensemble de la paroi 11 de l'emballage 12 qui est trans-- parente. Dans ce cas, la face imprégnée 9 de la pastille 8 est directement appliquée contre la face interne de la pa¬ roi 11.In the example illustrated in Figures 2 and 5, it is the entire wall 11 of the package 12 which is transparent. In this case, the impregnated face 9 of the patch 8 is directly applied against the internal face of the pa¬ king 11.
Le fonctionnement est le suivant : - tant que la pression à l'intérieur de la bouteille 1 ou de la boîte 12 reste à son niveau normalement prévu (valeur donnée s'il s'agit d'une boisson gazeuse normalement sous pression; valeur nulle s'il s'agit de produits alimentaires en conserve), l'utilisateur voit à travers la paroi trans- parente 5, 6 ou 11, la couleur correspondante des ditesThe operation is as follows: - as long as the pressure inside the bottle 1 or the box 12 remains at its normally expected level (value given if it is a carbonated drink normally under pressure; zero value in the case of canned food products), the user sees through the transparent wall 5, 6 or 11, the corresponding color of the said
"normales" du produit imprégnant la pastille 8 (par exemple une couleur rose pâle)."normal" of the product impregnating the tablet 8 (for example a pale pink color).
Si par contre la pression intérieure vient à augmenter de façon anormale (par exemple si les produits contenus dans la boîte 12 se sont mis à fermenter, ou bien si la boisson gazeuse contenue dans la bouteille 1 a été chauffée ou agitée), la pression interne augmente. Dès qu'elle dé¬ passe un seuil prédéterminé (et pour lequel a été choisi le produit imprégnant la pastille 8), l'utilisateur voit par transparence à travers la paroi, se modifier la couleur de la pastille 8. Initialement rose pâle, la couleur va par exemple virer au violet foncé. L'opérateur sait alors :If on the other hand the internal pressure increases abnormally (for example if the products contained in the box 12 have started to ferment, or else if the carbonated drink contained in the bottle 1 has been heated or stirred), the internal pressure increases. As soon as it exceeds a predetermined threshold (and for which the product impregnating the tablet 8 has been chosen), the user sees the color change through transparency through the wall. of pastille 8. Initially pale pink, the color will for example turn to dark purple. The operator then knows:
- ou bien que les produits en conserve dans la boîte 12 ont cessé d'être propre à la consommation;- Or that the canned products in box 12 have ceased to be fit for consumption;
- ou bien qu'il doit attendre avant de décapsuler la bou¬ teille 1, sous peine d'être aspergé par son contenu;- Or that he must wait before opening the bottle 1, otherwise he will be sprayed with its contents;
On peut même prévoir d'utiliser pour imprégner la pas- tille 8, un produit indicateur capable de supporter la température. Dans ce cas, un indicateur de pression selon l'invention pourrait également être prévu pour équiper la paroi d'un auto-cuiseur, cocotte-minute, ou autres usten¬ siles analogues. Dans tous les cas, l'utilisation du dispositif selon l'invention améliore la sécurité d'utilisation de l'embal¬ lage, et renseigne l'utilisateur sur l'état du contenu.One can even plan to use to impregnate the pad 8, an indicator product capable of withstanding the temperature. In this case, a pressure indicator according to the invention could also be provided to equip the wall with a pressure cooker, pressure cooker, or other similar utensils. In all cases, the use of the device according to the invention improves the safety of use of the packaging, and informs the user of the state of the content.
Bien entendu, on ne quitterait pas le cadre de l'inven¬ tion en réalisant d'autres variantes. Par exemple dans le cas d'une boîte ou d'un bocal, seul le couvercle pourrait être transparent et porter la pastille 8 à couleur chan¬ geante. Of course, we would not leave the scope of the invention by making other variants. For example in the case of a box or a jar, only the cover could be transparent and carry the patch 8 with a changing color.
