Abstract

The food marker consists of a label (1) carrying a substance (2) which undergoes a chemical reaction as a result of a rise in temperature, changing colour from its normal green to red. The colour change is irreversible and indicates to a consumer that a product has become defrosted since it was originally frozen - e.g. during storage or transport - and is unsafe to eat. The marker is preferably placed on the inside of a sealed package to ensure that it cannot be changed without the package being opened.

Description

La présente invention concerne une pastille incorporez aux emballages de produits surgelés et dont
le rôle est de détecter tout changement de température subit par ce produit afin de garantir la
validité de celici
Le Surgelé : un mot familier, un système de conservation révolutionnaire.The present invention relates to a lozenge incorporated into the packaging of frozen products and of which
the role is to detect any temperature change undergone by this product in order to guarantee the
validity of this
Frozen: a colloquial word, a revolutionary preservation system.

Du petit commercent aux glandes surface,du restaurant de quartier aux cantines d'entreprises, du célibataire pressé à la famille nombreuse, on le stocke, on le consomme, il est notre compagnon
de route.From small businesses to surface glands, from neighborhood restaurants to company canteens, from busy bachelors to large families, we store it, we consume it, it is our companion
of road.

Que son ulilisan soit professionnelle ou non ,les normes de conservation et d'utilisation sont rigoureuses et incontournables.Le respect de celles-ci est un gage de fiaicheur et de qualité. Whether its Ulilisan is professional or not, the standards of conservation and use are rigorous and essential. Respecting these is a guarantee of reliability and quality.

)Qui ne connaît pas les risques engendrés par tout écart à cette règlementation. Mais est-on à l'abri
d'une perse qui repose un sgelé dans un rayon de supermarché après l'avoir transporté
plus d'une heure dans son chariot à provisions,d'une panne d'électricité,d'un surgelé oublié sur la
table de la cuisine par un empêchement de dernière minute,d'un restaurateur malhonnête qui
recongèlera son stock invendu, d'un transporteur non soucieux de respecter les délais de
livraison...etc
Comment contrôler la validité d'un tel produit:
- une pastille(1), témoin d'un changement de température. Cette pastille est constituée d'une
substance (2) subissant une réaction chimique lors d'une élevation de température. Cette
réaction chimique se traduit par un changement de couleur.Normalement verte, celle-ci
devient rouge et ne change pl. d'état.) Who does not know the risks generated by any deviation from this regulation. But are we safe
of a persian who rests a frozen one in a supermarket ray after having transported it
more than an hour in his shopping trolley, a power outage, a frozen item left on the
kitchen table by a last minute impediment, from a dishonest restaurateur who
will refreeze its unsold stock, from a transporter who is not concerned with meeting the deadlines for
delivery ... etc
How to check the validity of such a product:
- a tablet (1), indicating a change in temperature. This tablet consists of a
substance (2) undergoing a chemical reaction when the temperature rises. This
chemical reaction results in a color change.Normally green, this
turns red and does not change pl. state.

Ce changement de couleur avertit le consommateur de la perte de validité du surgelé. This change of color warns the consumer of the loss of validity of the frozen food.

Celui-ci n'est plus consommable. It is no longer consumable.

n faut néanmoins se garantir d'une inviolabilité dans l'ouverture de l'emballage car la pastille peut
réagir d'un chargent thermique mais rien n'empêche le fraudeur de le changer de boite.However, it is necessary to guarantee inviolability in the opening of the packaging because the tablet can
react to a thermal charge but nothing prevents the fraudster from changing the box.

Un emballage par pression ou autre système utilisé actuellement garantit contre cette tricherie.  Pressure packaging or other system currently used guarantees against this cheating.
