  • the opening and closing means are in the form of a single zip, extending on both pleat panels and if necessary on the facing front and rear walls of the bag, making it difficult to close the bag, with the pleat in the condition recessed between the main walls of the bag.
  • the bag is closed with the pleat extending flat on the outside of the front and rear walls of the bag, held in that projecting position by the zip in the mutually interlocking condition.
  • that configuration is too wide and may interfere with bag positioning in storage areas in the user's home.
  • Figure 2 is a perspective view of the first preferred embodiment of the bag in a bag open condition for unloading the material, or product, contained in the bag;
  • Figure 3 is a perspective view of the first preferred embodiment of the bag, in a bag closed again condition after first opening for unloading the material or product;
  • Figure 4 is a cross-section of the first embodiment of the bag, according to the plane defined by the line IV-IV of Figure 1 ;
  • Figure 6 is a cross-section, similar to that of Figure 4, and relating to a second preferred embodiment of the bag;
  • FIGS 1 to 5 of the accompanying drawings show a first embodiment 10 of a bag, made of flexible film, in particular in the form of multi-layer plastic film, the bag 10 being designed to contain a corresponding product, in particular a food product, for example pet food or other food.

  • the inner face of the respective panel 18a, 18b of the pleat is facing a respective inner face or surface of a lateral portion of the respective bag main wall 12, 14.
  • the respective interlocking portion 41, 42, 43, 44 extends transversally or horizontally relative to the bag.
  • the respective pair of interlocking portions 41, 42 or 43, 44 is made as a single part.
  • the portions of the respective pair of interlocking portions 41, 42 or 43, 44 are connected to each other at a respective end 41b, 42b or 43b, 44b at the respective edge, in particular at the corresponding lateral edge 128, 148 of the bag.
  • the portions of the respective pair of interlocking portions 41, 42 or 43, 44 are pressed between opposed end longitudinal strips 128, 148, in particular joining or sealing together the corresponding main wall 12, 14 and the respective panel 18a, 18b of the pleat 18.
