Patent

CA 2229665

The disclosure relates to a pack for articles of food or other merchandise comprising a bag (30) and a carton form (40) for supporting a lower part of the bag having a base (41) with a central fold line (32) and walls (43) hinged to the base along further fold lines (44) to enable the carton and bag to be folded flat and to be erected to open the bag. The side walls of the lower part of the bag are secured to the side walls of the carton so that when the carton is erected by opening the folded base into a V-form, the bottom part of the bag is opened, and, as the V-form is progressively widened, the bag is tensioned by the walls moving apart until the base of the carton moves "over centre" and inverts to brace the lower part of the bag open to receive an article or articles to be packed therein.

L'invention porte sur un paquet pour articles alimentaires ou autres produits. Ce paquet comprend un sac (30) et une pièce en carton (40) destinée à soutenir la partie inférieure du sac. Cette pièce en carton dispose d'une base (41) munie d'une ligne de pliure centrale (32) et de parois (43) se pliant par rapport à la base le long d'autres lignes de pliure (44) afin que le carton et le sac puissent être mis à plat et montés pour ouvrir le sac. Les parois latérales de la partie inférieure du sac sont fixées aux parois latérales du carton de telle façon que, lorsque le carton est monté par ouverture de la base pliée selon un "V", le fond du sac est ouvert, et, à mesure que le "V" est progressivement élargi, le sac est tendu par les parois qui s'éloignent l'une de l'autre jusqu'à ce que la base du carton passe au-dessus du centre et s'inverse pour renforcer la partie inférieure du sac ouvert. Un ou des articles peuvent alors y être placés.
