Title
(EN) THE APPARATUS AND METHOD FOR ATTACHING HEAT EXCHANGE UNIT AND VALVE TO THE BOTTOM OF SELF-COOLING AND SELF-HEATING FOOD OR BEVERAGE CONTAINERS
(FR) APPAREIL ET PROCEDE DE FIXATION D'UNE UNITE D'ECHANGE DE CHALEUR ET D'UNE SOUPAPE SUR LE FOND DE CONTENANTS ALIMENTAIRES OU DE BOISSONS, A CHAUFFAGE OU REFROIDISSEMENT AUTONOME
Abstract
(EN)
A method and apparatus of forming a flange (14) in the bottom of a container (10) by first removing a portion of the container bottom (28) and then forming or swaying the material around the opening (28) to form a flange (14) extending away from the container bottom. A valve (24) and valve cup (22) assembly along with a heat exchange unit (16, 18, 32) are positioned adjacent the flange (14) and the combination is crimped to permanently affix the heat exchange unit (16, 18, 32) to the bottom of the container (12).
(FR)
L'invention concerne un procédé et un dispositif de formation d'un rebord (14) dans le fond d'un contenant (10). Ce procédé consiste d'abord à enlever une certaine portion du fond (28) du contenant puis à mettre en forme ou déplacer le matériau situé autour de l'ouverture (28), afin de former un rebord (14) qui s'étend en s'éloignant du fond du contenant. On a placé un ensemble soupape (24) et coupelle de soupape (22), de même qu'une unité d'échange de chaleur (16, 18, 32) au voisinage du rebord (14), et on a serti cette combinaison, de manière que l'unité d'échange de chaleur (16, 18, 32) reste fixée de façon permanente sur le fond du contenant (12).
