Definitions

  • the present invention relates to the field of sachets provided with complementary profiled closure shapes, actuated by a slider.
  • FIG. 1 illustrates an example of a slider 1 in keeping with the prior art.
  • Such a slider 1 is made of moulded plastic material and has a generally known structure.
  • this slider has a cross-section in an inverse “U” shape, and comprises a base 10 to which are connected two lateral and parallel wings 11 and 12 known as “flanks”.
  • the longitudinal axis of the slider corresponds to its direction of movement when it is installed on a sachet with complementary profiled shapes.
  • the flanks 11 and 12 extend parallel to this axis.
  • the internal space of the slider encloses means 13 adapted for stressing the complementary profiled closure shapes P 1 and P 2 of the sachet, by moving towards or moving away according to the direction of displacement of the slider along these profiled shapes.
  • the expression “internal space” means the space delimited by the base 10 and the flanks 11 and 12 .
  • Such a slider must be placed on a sachet S whereof the two sails are provided with complementary profiled closure shapes P 1 and P 2 .
  • the technique generally utilised to achieve this consists overall in deforming the slider so as to momentarily move its flanks 11 and 12 away from one another (arrow f of FIG. 1 ), moving the profiled shapes closer to “cinch” the latter and trap the protuberances T 1 and T 2 with which they are provided, then return the flanks to their initial position (arrows g of FIG. 1 ).
  • This displacement of the flanks is implemented for example by introducing tools “inside” the slider, applying them against the inner faces of the flanks and moving them away mutually.
  • the pivoting movement of the flanks does not translate by flexion of the material of the slider in the attachment zone of the flanks to the base. In fact, this zone is too thick and rigid to constitute a preferred folding zone.
  • U.S. Pat. No. 6,584,666 describes a slider provided with load pins.
  • the aim of the present invention is to further improve sliders of the prior art so as to produce satisfactory deformation with a level of acceptable mechanical stress, without risk of breaking.
  • the present invention accordingly relates to a slider for actuating profiled closure shapes, especially for a closure assembly equipping a sachet, comprising a base, two flanks, and means adapted for stressing respectively said profiled closure shapes, by moving towards or moving away according to the direction of displacement of the slider along profiled shapes, for moving the profiled shapes between a closed latch position and an open separated position, comprise a longitudinal groove which subdivides its internal space into two corridors.
  • This slider is remarkable in that said corridors extend according to median rectilinear and parallel axes which represent preferred fold lines when said flanks are moved away from each other
  • corridors represent preferred fold lines of rectilinear and parallel range, which very substantially reduces the risk of breaking, with acceptable levels of mechanical stress.
  • FIG. 2 is a perspective view of a slider according to the invention, presented in reversed position;
  • FIG. 3 is an end view of the slider of FIG. 2 ;
  • FIG. 4 is a bottom view of the slider of FIG. 2 ;
  • FIG. 5 is an end view of the slider of FIG. 2 , according to a direction opposite that of FIG. 3 ;
  • FIGS. 6 and 7 are views equivalent to those in FIGS. 4 and 5 , the flanks being illustrated in a spread position;
  • FIG. 8 is a view equivalent to FIG. 2 , the flanks being illustrated in a spread position;
  • FIG. 9 is a view similar to FIG. 3 , the flanks being illustrated in a spread position
  • FIG. 10 is a view of the slider according to the invention, in perspective.
  • the example of slider of the invention overall has a structure known per se, close to that of FIG. 1 .
  • the slider according to the invention has a cross-section in an inverse “U” shape, with a base 10 to which are attached two lateral and parallel wings (or flanks) 11 and 12 .
  • FIG. 2 it is presented in a position opposite to the one it occupies when it is in place on a sachet.
  • the internal space of the slider encloses means adapted for stressing complementary profiled closure shapes of a sachet (marked respectively P 1 , P 2 and S in FIG. 1 ), by moving towards or moving away according to the direction of displacement of the slider along these profiled shapes.
  • the expression “internal space” means the space delimited by the base 10 and the flanks 11 and 12 .
  • these means comprise a longitudinal groove 13 which extends according to the longitudinal median plane of the slider.
  • This groove 13 originating from material with the inner face of the base 10 , separates the internal space into two corridors C 1 and C 2 .
  • the groove extends downwards via an elongated central base 14 which overflows on either side of the groove 13 to constitute guide facets of a protuberance T 1 , T 2 (see FIG. 1 ), here in the form of a point of an arrow, situated above an associated profiled closure shape P 1 , P 2 .
  • a protuberance T 1 , T 2 (see FIG. 1 ), here in the form of a point of an arrow, situated above an associated profiled closure shape P 1 , P 2 .
  • Each facet is turned to the base 10 .
  • “Protuberance” denotes any means associated with the corresponding profiled shape, which allows the slider to cooperate with the sachet.
  • This base 14 comprises a first “wide” part 140 , in the general form of an iron base to be smoothed (that is, overall triangular when viewed from above), which is prolonged by a narrower part 141 .
  • the inner faces of the flanks 11 and 12 each bear 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 groove 13 , and its associated base 14 , the inner faces of the flanks 11 and 12 and their associated projections 112 , 122 , 113 , and 123 .
  • the corridors C 1 and C 2 have the form of throats with convergent edges.
  • each flank 11 and 12 extends a stiffening bar 110 , respectively 120 , of a thickness greater than the remaining part of the flank.
  • each bar 110 and 120 has on its free face, opposite the base 10 , a keying finger 111 , respectively 121 .
  • the slider could have the general structure described in French application No. 07 59545, in which load pins are provided in the extension of the flanks 11 and 12 .
  • the abovementioned corridors C 1 and C 2 extend according to rectilinear and parallel axes X-X′, which represent preferred fold lines.
  • these corridors are bordered laterally by the base of the groove 13 and by the foot of the projections 112 , 122 , 113 , and 123 .
  • the flanks 11 and 12 are moved apart from one another, for example by exerting a force on their inner face, as shown by arrows f of FIG. 8 . This allows the corridors C 1 and C 2 to be “opened” and enables placing of the profiled shapes.
  • the slider “folds” in those zones where there is least material. These “fold zones” correspond to the regions of the base 10 deprived of material outgrowth.
  • the letter P in FIG. 7 is used to mark the deformation planes of the slider.
  • the slider of the invention can be provided differently to that described here. It can especially be devoid of stiffening bars.
  • the above axes X-X′ could be marked visually, for example in the form of a line traced on the inner face of the base 10 , or even in the form of a groove made therein.
