Definitions

  • the present invention relates to the field of bags provided with complementary closure profiles actuated by a slider.
  • It relates more specifically to a slider for the actuation of closure profiles for a closure assembly equipping a bag.
  • the figure 1 appended represents an example of cursor 1 according to the state of the art.
  • Such slider 1 is made of molded plastic and has a generally known structure.
  • this slider has an inverted “U” -shaped section, and comprises a base 10 to which two lateral and parallel wings 11 and 12, called “flanks", are attached.
  • the longitudinal axis of the slider corresponds to its direction of movement when it is installed on a bag with complementary profiles.
  • Flanks 11 and 12 extend parallel to this axis.
  • the internal space of the slider includes means 13 adapted to urge the complementary profiles P 1 and P 2 closing the bag, in or out of the direction of movement of the cursor along these profiles .
  • internal space is meant the space delimited by the base 10 and the flanks 11 and 12.
  • Such a slider must be put in place on a bag S whose two sails are provided with complementary closure profiles P 1 and P 2 ,
  • the technique generally used for this purpose generally consists of deforming the slider so as to temporarily move its flanks 11 and 12 one from the other (arrow f of the figure 1 ), at bring it closer to the profiles to "girdle” the latter and imprison the protuberances T 1 and T 2 which they are provided with, then to bring the flanks back to their initial position (arrows g of the figure 1 ).
  • This displacement of the flanks is implemented for example by introducing tools "inside” the cursor, to apply them against the inner faces of the flanks and to separate them mutually.
  • the deformation is performed in predetermined regions of the base.
  • US Patent 6,584,666 describes a slider provided with biasing pins.
  • the present invention aims to further improve the sliders of the state of the art so as to obtain a satisfactory deformation with a level of acceptable mechanical stresses, without risk of rupture.
  • the present invention relates to a slider for actuating closure profiles, in particular for a closure assembly equipping a bag, comprising a base, two flanks and means adapted to respectively urge said closure profiles, in or out of the way according to the direction of movement of the cursor along the profiles, to move the profiles between a position in closing engagement and a separate opening position, comprise a longitudinal rib which subdivides its internal space into two corridors.
  • This slider is remarkable in that said corridors extend along straight and parallel median axes, which materialize preferred fold lines when said flanks are spaced apart from each other
  • the slider example of the invention has, overall, a structure known per se, close to that of the figure 1 .
  • the slider according to the invention has an inverted "U” -shaped section, with a base 10 to which two lateral and parallel wings (or flanks) 11 and 12 are attached.
  • the internal space of the slider contains means adapted to solicit complementary closure profiles of a bag (marked respectively P 1 , P 2 and S at the figure 1 ), in or near the direction of movement of the cursor along these profiles, by the expression "internal space” means the space delimited by the base 10 and the flanks 11 and 12.
  • these means comprise a longitudinal rib 13 which extends along the longitudinal median plane of the slider.
  • This rib 13 integral with the inner face of the base 10, separates the internal space into two corridors C 1 and C 2 .
  • the rib is extended downwards by an elongated central soleplate 14 which protrudes on either side of the rib 13 to form guide facets of a protuberance T 1 , T 2 (see FIG. figure 1 ), here in the form of arrowhead, located above an associated closure profile P 1 , P 2 .
  • Each facet is turned towards the base 10.
  • protuberance means any means associated with the corresponding section, which allows the cursor to cooperate with the bag.
  • This sole 14 has a first "wide” portion 140, generally shaped iron soleplate (that is to say generally triangular when viewed from above), which is extended by a narrower portion 141.
  • flanks 11 and 12 each bear, opposite the two parts 140 and 141 of the sole 14, a projection 112, 122, respectively 113, 123, which is also provided with a guide facet of a protuberance.
  • the corridors C 1 and C 2 are therefore delimited by the base 10, the rib 13 and its associated sole 14, the internal faces of the flanks 11 and 12 and their projections 112, 122, 113 and 123 associated, In other words, the corridors C 1 and C 2 have the shape of converged-edge grooves.
  • each sidewall 11 and 12 extends a stiffening bar 110, respectively 120, of greater thickness than the remaining portion of the sidewall.
  • each bar 110 and 120 has on its free face, opposite the base 10, a foolproof pin 111, respectively 121.
  • the cursor could have the general structure described in the French application no. 07 59545 , in which biasing lugs are provided in the extension of the sidewalls 11 and 12.
  • the opposite ends of the slider are shaped in arches 15, of greater thickness than the rest of its body.
  • the aforementioned corridors C 1 and C 2 extend along straight and parallel axes XX ', which materialize preferred fold lines.
  • these corridors are bordered laterally by the base of the rib 13 and the foot of the projections 112, 122, 113 and 123.
  • the cursor "bends" in areas where there is less material. These "folding zones” correspond to the regions of the base 10 devoid of material growth.
  • the slider of the invention may be provided different from that described here.
  • it may in particular be devoid of stiffening bars.
