Line Of Perforations Having Means For Preventing Leakage Before Opening Patents (Class 383/208)
  • Packing, in particular a packing for compressible packed goods
    Patent number: 5219229
    Abstract: The packing includes a side-folds bag (10). For opening the same, tear lines (22) are provided that start at the handle (18) and extend congruently at first. In the upper wall portions (14a, 14b), the tear lines diverge towards the corners (23), ending in the end wall (12) or converging again. For tearing the bag open, one has to pull at the four-layered portion (21) of the handle (18). The tearing is then done in a controlled manner with a take-out opening being made in the upper wall (14), which opening may extend into the end wall (12).
