Abstract

L'invention concerne un appareil pour ouvrir et distribuer des sacs plastiques. Cet appareil comprend une armoire extérieure (10) avec un rouleau continu (16) de sacs plastiques séparés par des lignes de soudure et des lignes de perforation ainsi que par des codes à barres. Ces sacs peuvent être distribués lorsque l'utilisateur tire sur un sac exposé, ce qui amène le sac à l'intérieur de l'armoire à se déplacer devant un lecteur de codes barres (30). Un dispositif de serrage (35) et des doigts (39) sont ainsi activés pour pré-ouvrir les sacs et un jet d'air (55) est prévu à l'extérieur de l'armoire, pour ouvrir le sac exposé, qui se situe en dehors de l'armoire. L'utilisateur tire alors le sac ouvert exposé au niveau des perforations. L'appareil peut distribuer automatiquement les sacs lorsque l'utilisateur active l'appareil.
