Patent CA-2008841-A1 (CA)
Inventor: DAGUERRE GERARD
IPC: B65D27/34
Filed: 1990-01-30
Abstract: Lors de la fabrication d'une enveloppe, des perforations sont quelques fois pratiquées en ligne discontinue afin d'en faciliter l'ouverture. Ce système a l'inconvénient de mettre en danger l'intégrité des documents insérés dans ce type d'enveloppe, puisqu'à l'ouverture de celle-ci les documents y étant insérés peuvent être déchirés en même temps que l'enveloppe. Dans la présente invention, les perforations ne sont plus une ligne fine discontinue sectionnant les fibres du papier, mais en ligne ayant un motif donnant de la largeur à la ligne discontinue de sorte que les fibres du papier sont broyées et soudées entre les différentes épaisseurs de papier plié qui forme une enveloppe. Cette soudure entre les différentes épaisseurs de papier chambre ainsi les documents à l'intérieur de l'enveloppe, les mettant hors d'atteinte de la partie détachable créée par ces perforations. Ce système d'ouverture rapide et facile ne requiert aucun outil. Il a l'avantage, dû à ces perforations, d'endomager de façon minimale l'enveloppe lors de son ouverture, de telle sorte qu'il est facile d'y réinsérer les documents après en avoir pris connaissance pour ainsi mieux les conserver ou pour les classer plus facilement.
