Abstract

An indicator which is designed to show if a frozen food product has been thawed at any stage between packing and sale consists of a block (1) of a frozen liquid contained in a perforated sachet (3) which can be made e.g. as part of the packaging (Y). In the event of the product thawing the liquid will also thaw and leak out, leaving evidence that the food product and not been continuously frozen and may be harmful to consume. In a variant of the design the frozen liquid block can be container in a transparent and non-perforated sachet and made from two different colours which mix together when thawed to produce a third colour. The frozen liquid can enclose a solid object which becomes at least partly exposed in event of thawing.

Description

La présente invention concerne un dispositif permettant d ' évaluer rapidement l'importance d'une éventuelle rupture de la chaîne du froid survenue sur des produits surgelés ou congelés même après recongélation. The present invention relates to a device making it possible to quickly assess the importance of a possible break in the cold chain which has occurred in frozen or frozen products even after refreezing.

Un produit alimentaire surgelé ou congelé subissant une décongélation accidentelle ne peut être recongelé pour une consommation ultérieure saine. Aussi, il serait nécessaire qu'un dispositif peu coûteux et simple permette aux consommateurs de pouvoir évaluer l'importance d'une rupture de la chaîne du froid, même après recongélation, et décider s'ils peuvent consommer ou pas le produit ou le maintenir en congélation ou non. A frozen or frozen food product undergoing accidental thawing cannot be refrozen for later healthy consumption. Also, it would be necessary for an inexpensive and simple device to allow consumers to be able to assess the importance of a break in the cold chain, even after refreezing, and decide whether or not they can consume the product or maintain it. whether frozen or not.

Jusqu'à présent les dispositifs COMUS pour cette fonction ne sont pas dans le grand commerce, certainement en raison de leur prix de revient ou de leur inefficacité. En effet ce dispositif doit pouvoir tolérer une brève rupture de la chaîne du froid due aux conditions normales de stockage et de transport. II doit pouvoir aussi fonctionner dans toutes les positions et évidemment être de taille raisonnable pour qu'il puisse être commercialisé dans l'industrie du produit alimentaire surgelé. Up to now, COMUS devices for this function have not been in the retail trade, certainly due to their cost price or their ineffectiveness. Indeed, this device must be able to tolerate a brief break in the cold chain due to normal storage and transport conditions. It must also be able to operate in all positions and obviously be of a reasonable size so that it can be marketed in the frozen food industry.

Le dispositif, selon l'invention, est constitué d'un volume de liquide déterminé, de préférence coloré, congelé à l'état solide dont la durée de décongélation correspond à la durée de rupture de la chaîne du froid déterminée trop importante par le fabricant pour que le produit soit consommable. Le dispositif est associé au produit alimentaire congelé avec son emballage. Il est de préférence visible de l'extérieur et peut faire partie intégrante de l'emballage à la guise du fabricant.  The device according to the invention consists of a determined volume of liquid, preferably colored, frozen in the solid state, the thawing time of which corresponds to the duration of break in the cold chain determined too long by the manufacturer. so that the product is consumable. The device is associated with the frozen food product with its packaging. It is preferably visible from the outside and can be an integral part of the packaging as desired by the manufacturer.

Suite à une éventuelle rupture de la chaîne du froid, une partie ou la totalité du volume congelé fusionnera, la partie liquide s'échappera du dispositif par simple gravité. S'il y a recongélation, c'est le nouveau volume solide ayant nettement changé d'aspect qui permettra aux consommateurs d'évaluer rapidement l'importance de la rupture de la chaîne du froid en rapport avec le produit alimentaire qui, lui, a peut-être gardé son aspect initial. Following a possible break in the cold chain, part or all of the frozen volume will merge, the liquid part will escape from the device by simple gravity. If there is refreezing, it is the new solid volume having clearly changed in appearance which will allow consumers to quickly assess the importance of the break in the cold chain in relation to the food product which has perhaps kept its original appearance.

Eventuellement, il est possible d'ajouter au volume à base d'eau un produit ralentissant sa décongélation si des problèmes de taille le nécessitent.Optionally, it is possible to add to the water-based volume a product slowing down its thawing if size problems require it.

Selon des modes particuliers de réalisation: dans le cas où il y a échappement du liquide, le dispositif peut être constitué:
- d'un simple glaçon de liquide congelé (1) ,qui fondra à l'intérieur ou à l'extérieur de l'emballage (Fig. 1).
According to particular embodiments: in the case where there is escape of the liquid, the device can be made up:
- a simple ice cube of frozen liquid (1), which will melt inside or outside the packaging (Fig. 1).

- d'un simple glaçon de liquide congelé de préférence coloré (l),emballé par un plastique de préférence transparent (2),percé d'orifices (3) permettant de faire échapper le liquide (Fig.2)
- d'un simple glaçon (1) de liquide congelé enrobant, contenant ou complétant un objet (X) qui facilitera la visualisation du dispositif (Fig. 3 et 4) qui peut être aussi enveloppé d'un plastique de préférence transparent (2) percé d'orifices (3) (Fig.5).
- a simple ice cube of preferably colored liquid (l), wrapped in preferably transparent plastic (2), pierced with holes (3) allowing the liquid to escape (Fig. 2)
- a simple ice cube (1) of frozen liquid coating, containing or supplementing an object (X) which will facilitate the visualization of the device (Fig. 3 and 4) which can also be wrapped in preferably transparent plastic (2) drilled with holes (3) (Fig. 5).

- l'objet (X) peut avoir une forme symétrique au volume de liquide congelé et peut n'enrober qu'une partie de l'objet. - the object (X) can have a shape symmetrical to the volume of frozen liquid and can only coat part of the object.

dans le cas où il n'y a pas d'échappement de liquide, le dispositif peut être constitué:
- d'un volume de liquide congelé (1) qui est coloré de deux ou plusieurs couleurs distinctes et enveloppé avec du plastique de préférence transparent étanche (2). Ainsi le liquide de fusion du volume congelé subissant une rupture de la chaîne du froid donnerait, par mélange de ses couleurs distinctes le constituant, naissance à une nouvelle couleur et suivant son aspect permettrait d'évaluer visuellement l'importance de la rupture de la chaîne du froid (fiv.7).
in the case where there is no escape of liquid, the device can consist of:
- a volume of frozen liquid (1) which is colored with two or more distinct colors and wrapped with preferably transparent waterproof plastic (2). Thus the liquid of fusion of the frozen volume undergoing a rupture of the cold chain would give, by mixture of its distinct colors constituting it, birth with a new color and according to its aspect would make it possible to visually evaluate the importance of the rupture of the chain cold (fiv. 7).

Dans tous les cas de figure, le volume de liquide peut être multicolore, le plastique de préférence transparent peut être souple, et tous ces dispositifs peuvent faire partie intégrante de l'emballage (Fig.6). In all cases, the volume of liquid can be multicolored, the preferably transparent plastic can be flexible, and all these devices can be an integral part of the packaging (Fig. 6).

Dans le cas où le dispositif est un simple liquide congelé (1) (de préférence coloré), emballé dans un plastique (2) (de préférence transparent) percé de toute part par des orifices (3), le dispositif reste dans le même état tant qu'il n'y a pas rupture de la chaîne du froid. Le cas échéant, le volume de liquide congelé (1) passera de l'état solide à l'état liquide et sa partie de liquide de fusion s'échappera par gravité, par les orifices d'évacuations (3). La partie solide s'il en reste à l'intérieur du plastique (2) même après recongélation, par son aspect ayant nettement changé, prouvera la rupture de la chaîne du froid. Pour ce dispositif comme pour les autres, une simple quantité d'eau colorée congelée peut faire office de volume de liquide congelé (1). In the case where the device is a simple frozen liquid (1) (preferably colored), wrapped in a plastic (2) (preferably transparent) pierced on all sides by orifices (3), the device remains in the same state as long as there is no break in the cold chain. If necessary, the volume of frozen liquid (1) will pass from the solid state to the liquid state and its part of the fusion liquid will escape by gravity, through the evacuation orifices (3). The solid part if it remains inside the plastic (2) even after refreezing, by its appearance having clearly changed, will prove the breaking of the cold chain. For this device as for the others, a simple quantity of frozen colored water can act as volume of frozen liquid (1).

Le dispositif peut adopter la forme que le fabricant qui exploite ce brevet décidera. n peut avoir la forme d'un logotype en l'occurrence celui de l'exploitant, la forme d'un objet, d'un personnage, d'un chiffre, d'une lettre, d'un symbole, ou n'importe quelle forme que ce soit. The device can take the form that the manufacturer who exploits this patent will decide. n can have the form of a logotype, in this case that of the operator, the form of an object, a character, a number, a letter, a symbol, or any whatever form.

C'est une garantie, voire même un label de qualité et de confiance pour l'industriel qui, en employant ce système, donne la possibilité à ses clients de vérifier si le produit est consommable. This is a guarantee, even a quality and confidence label for the manufacturer who, by using this system, gives his customers the possibility of checking whether the product is consumable.
