Definitions

  • the present invention relates to the field of bags comprising multiple closing / opening means, in particular based on complementary profiles.
  • EP-1405798 , WO2005 / 120981 , FR-2792812 describe devices based on a multiple-film closure fixed on a common film on both sides of closure profiles.
  • the document EP-1457428 describes a bag in which the closure means comprises two complementary closure profiles carried by respective support webs.
  • One of these sails is fixed in a first zone on a film and then returned to itself to be fixed in a second zone on the second support sail and finally is fixed on a third zone on the support film.
  • the first fixing zone and the third fixing zone are arranged on either side of the closure profiles.
  • a packaging bag comprising a multiple closing / opening means fixed to a film, the multiple closing / opening means comprising two profiles of complementary closure fixed on respective support webs, characterized by the fact that one of these support webs is a wide web returned on itself and on the multiple closing / opening means for overlapping the entire closure means, and fixed in two distinct areas on the film on either side of the multiple closing / opening means.
  • the invention also relates to multiple closing / opening means for producing the aforementioned packaging bags.
  • the invention also relates to a method of manufacturing packaging bags comprising the steps of i) providing a multiple closure / opening means comprising two complementary closure profiles fixed on respective support webs, ii) return, the one of these support webs, formed of a wide web, on itself and on the multiple closing / opening means in order to overlap the totality of the closure means, and iii) securing, this wide web, in two distinct zones on a film, on both sides of the multiple closing / opening means.
  • the pouches according to the present invention essentially comprise a bag body 10 partially shown in the accompanying figures and a multiple closure / opening means 20 fixed to the bag body at the mouth thereof.
  • the bag body 10 and the multiple closure / opening means 20 can be subject in themselves many variants.
  • the bag body 10 is formed based on a film 12 comprising two main sheets 14, 16 parallel to each other.
  • the two main sheets 14, 16 may be formed from a single film 12 of tubular shape closed at its ends, or a film folded on itself to form the two main sheets 14, 16 mentioned above, connected together on three sides.
  • the two main sheets 14, 16 may be formed from sections of respective films initially independent, interconnected by bonding or welding on four sides.
  • the film 10 may be made of any suitable known material. It is preferably made of thermoplastic material, polyethylene or polypropylene, for example.
  • the invention is not limited to this particular provision. It encompasses all types of materials, including all composite materials.
  • the multiple closing / opening means 20 can also be the subject of numerous alternative embodiments.
  • the multiple closure / opening means 20 comprises two supporting webs 22, 24 respectively supporting a closure element 23, 25 such as a complementary male element and a female element as illustrated in FIG. figure 1 and in FIG. 3 or any equivalent structure, for example based on hooks as illustrated in FIG. figure 2 .
  • a closure element 23, 25 such as a complementary male element and a female element as illustrated in FIG. figure 1 and in FIG. 3 or any equivalent structure, for example based on hooks as illustrated in FIG. figure 2 .
  • the multiple closing / opening means 20 is equipped with a slider 30.
  • the slider 30 is formed of a base provided with two lateral flanks and a central wall.
  • the wall defines in combination with the lateral flanks two non-parallel channels which respectively receive one of the closing profiles 23, 25.
  • the slider 30 When the slider 30 is moved in a first direction, the slider tends to approximate and engage the closure bars to close the bag. On the contrary, when the slider is moved in the second opposite direction, it tends to separate the closure profiles 23, 25 and consequently to open the bag.
  • one of the support webs 22, 24 is a wide web, turned over on itself and on the multiple closing / opening means 20 to overlap the entire closure means and fastened in half. distinct zones 40, 42 on the film 10, on either side of the multiple closing / opening means 20.
  • the present invention may be the subject of various embodiments.
  • the two zones 40, 42 of welding of the web 22 on the film 10 are opposed relative to the closing means 20, that is to say located on either side, respectively thereof.
  • the film 10 may comprise a pre-cut or weakness zone, referenced schematically 18, between the two soldering zones 40, 42.
  • the support web 22 may itself have a zone of weakness or pre-rupture 28 in its section located between the two welding zones 40 and 42.
  • the web 22 overlapping the closure means serves both as an opening control and a sealing means.
  • the veil 22 As the veil 22 is not broken, the user knows that the bag has not been opened. On the contrary, at the first opening to access the contents of the bag, the veil 22 must imperatively be broken.
  • the support web 22 is fixed at 40 and 42, according to the first embodiment, on the film 12, on either side of the closure means 20.
