Definitions

  • the present invention relates to the field of automatic formation, filling and closing of packaging, comprising closing devices, for example with male profiles and complementary female.
  • Such machines are often called FFS, corresponding with the initials of the English expression "Form, Fill and Seal machines”.
  • Document US 4,909,017 describes a process in which bags are provided with a closure device, when they are formed on an FFS machine.
  • the bags are formed from a film of material thermoplastic.
  • the film is in the form of a strip of material extending between two longitudinal free edges with reference to its displacement. This film is unwound upstream of a filling chute.
  • the device closure is arranged on the film, also upstream of the chute, transversely to the direction of movement of the film.
  • the closing device is made up of two strips with profiles complementary.
  • a first strip of the closure device is welded on the film upstream of the chute, on a part of the film intended for form a first bag wall.
  • the sachet is then formed into wrapping the chute and welding the two longitudinal edges of the film.
  • the second closure strip is then welded downstream of the chute on a second bag wall.
  • Document US 4,655,862 also describes a method for forming resealable bags, on FFS machines, during which sachets are provided with a closing device which is arranged perpendicular to the direction of formation of these bags.
  • This closing device is removed in upstream of the filler neck, on a film in the form of a single bandaged.
  • This strip comprises at least one transverse folding zone at the strip, so that the strip can be folded back on itself and put in place opposite, regions of the strip able to cooperate together to ensure closing the bag.
  • a process for manufacturing a film intended forming bags comprising a step of moving the film and to be sequentially fixed on the film and transversely with reference to the direction of movement thereof, a closure device comprising a first strip supporting at least one closing closure profile with another closure profile which is complementary to and supported by it by a second strip, or part of the first strip, which will be fixed to the film subsequently, characterized in that each strip comprises at less a veil extending widely laterally on one side of the profiles supported by each strip.
  • Such sails give the invention a number of advantages. Thanks to its larger cross-sectional area, a device for implementation of the method according to the invention is easily carried and positioned. In addition, the sails can be set at temperatures low enough to avoid damaging the profiles.
  • FIG 1 three closing devices 1 are shown for the implementation of the method according to the invention.
  • These devices 1 include two bands 2, 4.
  • Each band 2, 4 includes sails 6, 8 and sections 10, 12.

  • Each strip 2, 4 can comprise several sections 10, 12 similar, for example, to those described above. These profiles are then parallel to each other.
  • the bands 2, 4 comprise respectively a first veil 6 and a second veil 8 which extend widely laterally on one side of the section or sections 10, 12.
  • this first veil 6 and this second veil 8 can be replaced by a first 6 and a second 8 parts of a single veil to join the two bands 2, 4.

  • the profiles 10, 12 of the closure device 1 of FIG. 1c are located at near a free sail 6, 8.
  • These devices are particularly suitable for being fixed on the film 50, by the method according to the invention, since the surface of the webs 6, 8 is such that it makes it possible to weld these webs 6, 8 on the film 50 on an area of these which is not under the profiles 10, 12. This facilitates the installation of the closure device 1 and the welding of this one on film 50.

  • This membrane 26 is welded over the entire length of the device 1, by example near the peelable weld 18, between this strip of peelable weld 18 and the profile 10.
  • This sealing membrane 26 extends laterally in the direction of the other profile 12 by covering the profile 10.
  • FIG 14 shows the device 1 shown in Figure 13 in closed position. We can see that the waterproofing membrane 26 is taken between profiles 10 and 12.
  • Figure 15 shows a device similar to that of Figures 13 and 14, with the difference that it has two sealing membranes 26 each welded to one of the sails 6, 8.
  • Figures 16 to 20 show variants of a device 1 of closure comprising at least one peelable weld strip 18, 20, 21 and a line of perforations 19.
  • Figure 16 is shown a device 1 which has a band single peelable weld 21 fixed between the webs 6 and 8.
  • the line of perforations 19 is on the edge of the peelable weld strip 21 located towards the outside of the bag 30 and between the sails 6 and 8.
  • This line of perforations extend over the entire length of the device 1. It allows tear the peelable weld more easily when the walls are moved apart 32 and 34 to open the bag 30.
  • Figure 17 shows a device in the open configuration.
  • the line of perforations 19 is located between the sections 10 and 12, at approximately equal distance from each of them, at the joint of the sails 6 and 8.
  • Strips of peelable weld 18, 20 run along this line of perforations 19 over the entire length of the closure device 1.
  • FIG. 18 shows, in the closed position, the device of the Figure 17 fixed on a bag 30.
  • a bag 30 To open the bag 30, we spread its walls 32, 34, which induces a stress between the walls 6 and 8 and causes the tear of the line of perforations 19.
  • This bag 30 can possibly be closed by pressing the strips of peelable solder 18 and 20, if they are for example adhesive tapes. This then ensures a greater seal than with cooperation alone profiles 10, 12 with each other.
  • Figures 19 and 20 show a closure device such as that shown in Figures 17 and 18, further comprising a membrane sealing 26.
  • This sealing membrane 26 is welded to the web 8, near the peelable weld strip 20 and extends laterally to the above profile 12.
  • FIG. 21 represents a closure device fixed on a film 50 (for example before passing over the filling chute 130 of a FFS machine).
  • This device 1 consists of two sails 6, 8 joined between them to form a U.
  • the veil 6 is fixed to the film 50 by two points of welding 47, 49, located on the wall 6 on either side of the direction longitudinal profile 10. These welding points 47, 49 can be made before folding the device on itself to cooperate the sections 10, 12 between them.
  • the welding points 47, 49 can be more or less extended in the longitudinal direction of the bands 2, 4. They may optionally also extend over the entire length of the device 1.
  • the device can only be retained in the film 50 by a single 49 of these welding points 47, 49.
  • point 49 is the one located downstream from displacement D of the film 50, so as to prevent the device 1 from turning over when passing over the filling chute 130.
  • one of these welding points 47, 49 is located on the side of the profiles 10, 12 which will be inside the bag 30 once this one formed. In this case, no welding point will be made equivalent opposite, on the second veil 8. In this way, we constitutes a hinged configuration which offers better resistance to internal pressure in the bag 30 (Figure 22).
  • the invention also extends to a machine for manufacture of a film 50 intended to form sachets 30, comprising first transverse welding means 110, relative to the direction for moving the film 50, capable of fixing a closure device 1 provided sails 6, 8 on the film 50.
  • a film 50 is thus obtained for the formation of sachets 30 provided with closing devices 1.
  • closing devices 1 do not are fixed to the film 50 only by a first veil 6. Bags 30 can then be shaped and completed from this film 50 provided with closure 1, either on a bag forming machine 30 to be used and filled later, either on an FFS machine.
  • the invention therefore also extends to a training machine, automatic filling and closing, which includes first welding means 110, transverse, upstream of a chute 130 of filling and second transverse welding means 116 downstream of the chute 130.
  • first welding means 110 transverse, upstream of a chute 130 of filling
  • second transverse welding means 116 downstream of the chute 130.
  • the concept of transversality being understood here with reference to the direction of movement of the film 50.
