Definitions

  • the present invention relates to the field of bags equipped with a closure assembly adapted to allow successive multiple openings / closings on demand.
  • the present invention relates to the manufacture of such bags using closure assemblies comprising two profiles of thermoplastic material comprising complementary elements, adapted to be alternately engaged to allow the closure of the bags and separated to allow the opening of sachets and access to their contents.
  • the aforementioned complementary elements are formed of hook structures or elements respectively male and female provided on the two sections.
  • a closure and bag assembly according to the preamble of claim 1 is disclosed in US 3371696.
  • FIGS. 1 and 2 show two known embodiments of closure assemblies according to the state of the art.
  • FIGS. 1 and 2 attached, comprise sets comprising two supporting webs 10, 20 carrying respective complementary elements 12, 22. According to the non-limiting representation given in FIGS. 1 and 2, these elements 12, 22 are formed of sections respectively male and female.
  • the two webs 10, 20 are provided on their internal surface facing, and on the outside of the profiles 12, 22, longitudinal grooves referenced respectively 14 and 24.
  • the closure assembly illustrated in FIG. 2 comprises similar longitudinal ridges 16, 26 on the outer surface of the support webs 10, 20.
  • grooves 14 and 24 are to facilitate the handling of the support webs 10, 20 to ensure the control at the opening and closing of the assembly, ie respectively to exert a biasing to separate the profiles to separate the elements 12, 22 and exercise a bias tending to bring the profiles to put the two elements 12 and 22 in engagement.
  • Streaks 14, 24, 16, 26 can indeed guide the fingers of the user.
  • the grooves 14 and 24 also have the function of limiting the zone of contact between the two sections of the closure assembly and consequently avoiding the risks of welding when fastening to a movie.
  • the present invention aims to improve the known closure assemblies.
  • a closure assembly comprising two thermoplastic material sections comprising complementary elements adapted to be alternately engaged to allow the closing of bags and separated to allow the opening of the bags and access to their contents, said complementary elements being carried by respective support webs, characterized in that only one, and only one, of the support webs has grooves projecting on its inner surface directed towards the other. sail.
  • the other support web is provided with ridges projecting on its external surface.
  • the present invention also relates to bags made using such a closure assembly and a method and a machine for manufacturing such bags.
  • FIG. 3 appended hereto shows a closure assembly according to the present invention comprising two substantially parallel support webs 100, 200 respectively comprising a male closure element 110 and a complementary female closure element 210.
  • Each of the two supporting webs 100, 200 extends on either side of the element 110, 210 respectively.
  • only one and only one of the support webs 100, 200 is provided with longitudinal grooves 230 on its internal face directed towards the other support sail 100, and this on the portion of the support web 200 located on the outside of the profiled elements 110, 210 relative to the center of the bag.
  • FIG. 4 shows a variant embodiment which differs from that illustrated in FIG. 3 by the fact that the second support web 100 also has on its external surface a series of projecting longitudinal grooves 130.
  • longitudinal is meant that the grooves 130 and 230 extend parallel to the elements 110, 210.
  • the whole of the closure that is support webs 100, 200, complementary elements 110, 210 and ridges 130, 230, is made of thermoplastic material, very advantageously by extrusion.
  • FIG. 5 represents an alternative embodiment that differs from FIG. 4 in that the arrangement of the striations is reversed.
  • the inner ridges 130 are provided on the inner face of the web 100 carrying the male member, while the outer grooves 230 are provided on the outer surface of the web 200 carrying the female member.
  • FIG. 6 shows an alternative embodiment in which the complementary elements 110, 210 are formed of a hook structure.
  • the general structure of such a closure assembly based on hook-type complementary elements is well known to those skilled in the art and will therefore not be described in detail later.
  • FIG. 7 shows an alternative embodiment in which the two supporting webs 100, 200 are joined together in the form of a U-shaped structure by a connecting web 150 disposed on the inside of the closure assembly. , that is to say the side opposite to the area of the supporting webs 100, 200 carrying the projecting ridges 130, 230.
  • each streak, of triangular section has a height and a width at the base of the order of 10th of mm.
  • the difference between two adjacent ridges is preferably between 0.5 and 2 mm.
  • the number, the density, the size and the section of the grooves 130, 230 may be the subject of numerous variants. They are not limited to the illustrations given in the appended figures. In particular, it is possible to provide ridges having a generally triangular section as illustrated in FIGS. 3 to 6 and 8 or a generally rounded section as illustrated in FIG. 7. Streaks 130, 203 that are almost contiguous may also be provided, as illustrated in FIG. Figure 3 or clearly spaced, as shown in Figures 4 to 8.
  • streaks provided on the outer surface of a web may be identical to, or different in number, density, section and size, streaks provided on the other web.
  • the closure assembly according to the present invention can be made, for example by extrusion, in the form of a self-assembly intended to be attached to a film adapted to compose a bag or be directly material on such a film.
  • closure assemblies according to the present invention offer the advantage of allowing easy handling thanks to the presence of ridges 130, 230, without any risk of blockage likely to result, on certain closure assemblies according to the state of the art. , contact between two sets of streaks opposite.
  • the present invention also applies to windows comprising complementary elements veiours / hook type.
