Description

  

  Dispositif pour l'ouverture d'un emballage en papier tel qu'une enveloppe de lettre  ou un sac ou cornet.    L'objet de la présente invention est un  dispositif pour l'ouverture d'un emballage en  papier tel qu'une enveloppe de lettre ou un  sac ou cornet.  



  Le dessin annexé montre, à titre d'exem  ple, deux formes d'exécution de l'objet de  l'invention.  



  La     fig.    1 est une vue partielle d'une en  veloppe avec dispositif selon la première  forme d'exécution.  



  La     fig.    2 est une vue partielle d'une en  veloppe avec dispositif selon la deuxième  forme d'exécution.  



  Le dispositif représenté à la     fig.    1 est  constitué par un fil souple 2 fixé le long  d'un côté de l'enveloppe 1 au moyen de  points de couture faits à la machine à coudre  par exemple. Une amorce de déchirure con  stituée par une entaille 3 est pratiquée prés  des extrémités de la couture ainsi obtenue;  cette entaille 3 est destinée à faciliter le  début de la déchirure qui se produira en    tirant le fil 2 à partir de ladite amorce de  déchirure, les extrémités de ce dernier étant  placées légèrement en retrait des bords cor  respondants de l'enveloppe.  



  Dans la forme d'exécution représentée à  la     fig.    2, l'amorce de déchirure est constituée  par des petits trous 3' alignés et placés prés  les uns des autres.



  Device for opening a paper package such as a letter envelope or a bag or cone. The object of the present invention is a device for opening a paper packaging such as a letter envelope or a bag or cone.



  The appended drawing shows, by way of example, two embodiments of the object of the invention.



  Fig. 1 is a partial view of a casing with a device according to the first embodiment.



  Fig. 2 is a partial view of a casing with a device according to the second embodiment.



  The device shown in FIG. 1 is formed by a flexible thread 2 fixed along one side of the casing 1 by means of stitches made on the sewing machine for example. A tear initiation constituted by a notch 3 is made near the ends of the seam thus obtained; this notch 3 is intended to facilitate the onset of the tear which will occur by pulling the thread 2 from said tear initiator, the ends of the latter being placed slightly behind the corresponding edges of the envelope.



  In the embodiment shown in FIG. 2, the tear initiator consists of small holes 3 'aligned and placed close to each other.
