Description

Dispositif de récipient alimentaire auto-chauffant  Self-heating food container device
La présente invention concerne le domaine des récipients alimentaires auto-chauffants. The present invention relates to the field of self-heating food containers.
Lors de l'exercice de nombreux professions ou loisirs, un four ou une plaque chauffante, plus généralement un équipement de cuisine fixe est souvent indisponible. On connaît dans le passé des équipements isolants visant à conserver un produit alimentaire au chaud. Toutefois, la conservation de la chaleur n'excède pas quelques heures et un équipement chauffant s'avère indispensable pour porter le produit alimentaire à la température souhaitée laquelle doit être plus élevée que la température finale de consommation au bout de quelques heures. When exercising many professions or hobbies, an oven or a hotplate, more generally a fixed kitchen equipment is often unavailable. In the past, insulating equipment has been known for preserving a hot food product. However, the preservation of heat does not exceed a few hours and heating equipment is essential to bring the food product to the desired temperature which must be higher than the final temperature of consumption after a few hours.
C'est la raison pour laquelle différents types de récipients auto-chauffants ont fait l'objet de recherches. On peut citer à cet égard les documents EP 826 721, DE 3725852, WO 2007/002473, FR 2 659 940, FR 2 656 596 à titre d'exemple. Aucun d'entre eux ne donne pleinement satisfaction que ce soit en termes de facilité d'utilisation, de sécurité, de conservation, de résistance aux intempéries et de coût. La présente invention vient améliorer la situation. This is the reason why different types of self-heating containers have been researched. In this respect, mention may be made of the documents EP 826 721, DE 3725852, WO 2007/002473, FR 2 659 940 and FR 2 656 596 by way of example. None of them are fully satisfactory in terms of ease of use, safety, conservation, weather resistance and cost. The present invention improves the situation.
