  • the method according to the invention provides for the step of sealing the opening and closing device 1 with the respective base 2 on the gusset element 55 of the flexible container 50. This is carried out by reciprocally diverting the upper end portion 52c of the first wall 52 and the upper end portion 53c of the second wall 53 so as to lay down in a substantially complete manner the gusset element 55 (that is to say along a substantially horizontal plane) and then sealing the base 2 on the gusset element 55 ( Figure 7 ).
  • the sealing of the base 2 on the gusset element 55 is carried out with the aid of two opposite rigid blocks 60 with a substantially wedge shape, said blocks 60 being arranged by means of a movement of reciprocal proximity (arrows B and C of Figure 7 ) close to the first wall 52 and the second wall 53 respectively slightly below the upper end portion 52c of the first wall 52 and the upper end portion 53c of the second wall 53.
  • These blocks 60 each have a substantially horizontal upper surface 61 whereon the upper end portion 52c of the first wall 52 and the upper end portion 53c of the second wall 53 are advantageously held and supported, previously reciprocally removed during the application (for example by pressing) of the base 2 on the gusset element 55 (arrow D of Figure 7 ), facilitating thereby and making more effective the sealing of the base 2 to the gusset element 55.
  • the method according to the invention provides, after having moved the rigid blocks 60 away from the first wall 52 and from the second wall 53 (arrows E of Figure 8 ), for the step of folding the base 2 with the upper end portion 52c of said first wall 52, the upper end portion 53c of said second wall 53 and with the gusset element 55, of sealing of at least part of the folded base 2 to the sealing surfaces 7 of the flange 6 of the pourer body 3 of the device 1 (arrows F of Figure 8 ) and of sealing one to the other the abovementioned folded end portions 52c and 53c of said first wall 52 and said second wall 53 in end zones of the gusset element 55 not affected by the coupling with the flange 6 and optionally affected by a residual portion of the base 2 (arrows G of Figure 8 ), obtaining thereby a package 70 according to the invention as shown in Figure 9 .
  • the folding of the base 2 around the sealing surfaces 7 of the flange 6 is facilitated by the folding lines 12, 13 and 14 described above. More particularly, with reference to Figures 8a and 8b , the folding of the laid down base 2, as shown schematically in Figure 8a , together with a portion of the pourer body 3 after application of the same on the gusset element 55 (as illustrated previously with reference to Figure 7 ) entails a slight lowering of part of the central portion 2a of the base 2 at opposite peripheral zones not affected by the through hole 11 together with the lowering of the portion of the gusset element 55 sealed at these zones, this lowering being facilitated by the third folding lines 14 (arrows H of Figure 8b ).
  • the folding of the base 2 entails the raising of the peripheral portion 2b of the base 2 with the upper end portion 52c of said first wall 52, the upper end portion 53c of said second wall 53 and the remaining part of the gusset element 55, this raising being facilitated by the first folding lines 12 and by at least part of the second folding lines 13 (more particularly the lines 13 extended longitudinally).
  • the base 2 goes to form, once folded, a pocket whose internal profile is substantially complementary to the external profile of the flange 6, making thereby easier and more accurate the sealing of the base 2 to the surfaces 7 of sealing of the flange 6 and the sealing of the folded end portions 52c and 53c of said first wall 52 and said second wall 53 in the end zones of the gusset element 55 not affected by the coupling with the flange 6 and affected optionally by a residual portion of the base 2.
  • the consumer To open the package 60 according to the invention (first opening), it is sufficient for the consumer to turn the cap stopper 4 in a predetermined direction (for example the anticlockwise direction indicated by the arrow H), advantageously gripping on the knurling 47 of the cylindrical shell 46, until reaching the lower end stop position of the eccentric blade 42 corresponding to the maximum advancement of said blade in the bag 50.
  • This rotation entails the lowering of the neck 22 with the relative blade 42 and of the cap stopper 16 rotatably integral therewith and the perforation of the bag 50 by the blade 42 at the gusset element 55 after the blade 42 has traversed the hole 11 of the base 2.
  • the lowering of the neck 22 from the upper end stop entails the passage of its annular ridge 29c below the lower annular ridge 29b of the collar 5 (thanks to the force of the rotation and to the fact that the component material of the annular ridges 29a and 29b has adequate elasticity) and ends on reaching of the lower end stop with the blocking of the neck 22 to the collar 5 by means of slotted coupling of the cylindrical shell 36 at its internal annular recess 39 with the teeth 10 of the annular band 9.
  • the portion of the gusset element 55 situated at the through hole 11 of the base in addition to finding itself in a slightly raised position compared to these end zones, is also sufficiently taut, facilitating thereby the perforation of the bag 50 by the blade 42.
  • the package 1 can also be readily closed again given that the consumer, on each dispensing of a required quantity of the fluid product contained in the bag 50, can easily provide for closure again of the package 60 by screwing the cap stopper 4 to the upper end portion 31 of the neck 22, the latter being restrained firmly in position by the slotted coupling of the cylindrical shell 36 at its internal annular recess 39 with the teeth 10 of the annular band 9.
