Abstract

L'invention concerne un emballage distributeur (200) doté d'un moteur thermique intégré à usage unique pour un produit, lequel emballage présente une barquette à produit supérieure (210) pourvue d'un évidement à produit (216) destiné à contenir le produit, un opercule pelable (202) étant fixé de façon amovible à la barquette à produit supérieure (210), recouvrant ainsi le produit contenu dans l'évidement à produit (216). Une barquette de base inférieure (230), présentant un évidement à moteur thermique (232), est fixée au fond de la barquette à produit supérieure (210). Un moteur thermique est contenu dans l'évidement à moteur thermique. Ce moteur thermique présente une pochette d'oxydation (220) contenant un oxydant et un combustible réactif à cet oxydant. L'application d'une pression sur la pochette d'oxydation (220) entraîne la rupture ou l'éclatement de cette pochette d'oxydation (220), l'oxydant étant ainsi déversé dans l'évidement à moteur thermique (232), mélangé au combustible et amené à réagir pour produire de la chaleur.
