  • the figure 12b is a side view of the upper end (23) of the bag showing a transverse tear line (29), typically initiated by a notch (290), so as to separate the upper portion (291) during the first opening.
  • the figure 12c schematically represents the end (23) after tearing the upper part (291), before the opening of the reclosing means (28) which is provided with the main orifice (22), while the figure 12d is analogous to the figure 12c but after separation of the walls and the two parts of the "Zip” or a means equivalent to the "Zip", for example two cold sealing and reclosable range.
  • This modality is analogous to the previous one (modality i according to the figure 12a ), but differs in that the opening of the two secondary compartments (30A ') is close to the lower end (24) of the main bag (2), and not its upper end (23), as on the figure 12a .
  • the figure 14 represents a bag (1), with a secondary wall (3A ') external to the main bag (2), as illustrated in FIG. figure 3a ), but with a secondary orifice (31) and a lateral secondary closure means (37) facing one of the lateral edges (21) of the main bag (2).
  • the arrow with the mark (31) illustrates the filling direction of the secondary compartment (30A ') or access to its contents (4B), while the arrow with the marker (22), 90 ° from the previous one, illustrates the filling direction of the main bag (2) or access to its contents (4A).
  • the secondary films (7, 7 ' are folded films.
  • the Figures 10a to 10b are similar to figures 6b and 7b , but with a relative position of the secondary films (7, 7 ') and reinforcing tape (8, 8') inverted: the reinforcement strips (8, 8 ') are central in the production line (10) shown in FIGS. Figures 10a and 10b , while they are lateral on the figures 6b and 7b and reciprocally with regard to the secondary films (7, 7 ').
  • the reinforcing strip comprises two distinct strips (8 and (8 ') on the figure 10a , while there is only one band (8) on the figure 10b , which strip is then cut longitudinally along the cutting line (110).
  • the secondary film (7) is exterior.
  • the reinforcing strips (8, 8 ') are lateral, as on the figures 6b and 7b , the bag (1) obtained according to the process schematized by the figure 10c being similar to that of the figure 3a .
  • the Figure 6a and 6b similar to Figures 5a and 5b , correspond to the manufacture of bags (1) of the type represented on the figure 8b .
  • a folded secondary film (7) is unwound between the main films (6) and (6 ').
  • the weld zones comprise, in addition to the peripheral zones represented on the figure 5a cross-hatched areas intended to form the fastening edge (32). These transverse zones are typically formed using a heat shield or a non-sealing film (9), these zones being formed for example before the formation of the peripheral sealing zones, so as to be able to temporarily introduce / remove the screen (9). stacking the films (6, 6 ', 7, 8 or 8') to be heat sealed.
  • the arrows represent the heat sealing zones and the movement of the sealing jaws.
  • the folded secondary film (7) has been replaced by two films (7) and 7 ').
  • This modality provides, as illustrated on the Figures 10a or 10b , that the reinforcing strip (8, 8 ') is central, so that, since the opening of the bags is typically oriented outwards, it is thus possible to introduce into the bag, if necessary, a heat shield ( 9), or to secure to the bag, by a lateral supply, any useful accessory.
