Definitions

  • the present invention relates to a pouring assembly and closure cap made of plastic material, for bottles or similar containers, comprising a pouring device with means for its attachment to a bottle neck or a similar container orifice, an attached capsule of removably on the pourer so as to cover and close the latter, and tamper-proof means comprising a guarantee strip detachably connected to the pourer and cooperating with the capsule so as to prohibit the removal of the capsule without prior removal from the warranty strip.
  • the capsule On known pouring assemblies and caps of this type, the capsule is retained on the pourer by snap-fastening or by screwing, and the guarantee strip extends from the pourer upwards over a greater or lesser part of the height. of the capsule.
  • the purpose of this guarantee strip is to prevent gripping of the capsule as much as possible, and therefore the possibility of removing the capsule from the pourer without tearing off or damaging this strip.
  • the inviolability provided by these known assemblies is not always satisfactory, in particular in the case where the capsule is retained on the pourer, not by screwing or snap-fastening, but simply by the tightening exerted on the pouring spout by an internal skirt. seal formed on the capsule so as to cooperate by forcing with the spout.
  • the present invention relates to a pouring assembly and closure cap offering improved inviolability, without increasing the cost price of the assembly.
  • the guarantee strip detachably connected to the pourer extends, from the pourer, over the entire height of the capsule and has, at its free end, a return inner ring which covers the upper outer edge of the capsule.
  • the guarantee strip of the assembly according to the invention therefore surrounds the capsule not only over its entire height, but also at the place of its upper edge, so that it is impossible to grasp the capsule as long as the strip warranty has not been removed.
  • the capsule has, on its upper face, an annular shoulder against which bears the end of said interior return of the guarantee strip.
  • the interior return of the guarantee strip is advantageous for the interior return of the guarantee strip to be interrupted by notches distributed around the periphery. These notches provide the internal return of the guarantee strip with sufficient elasticity to allow the demoulding of this return by elastic deformation.
  • the inside return of the guarantee strip can be welded to the capsule.
  • the guarantee strip is advantageous for the guarantee strip to be connected to the pourer by a continuous connection line all around the perimeter and by reinforced connection bridges distributed around the perimeter.
  • the assembly according to the invention may comprise a film extending over the upper face of the capsule and welded to the inside return of the guarantee strip, around the entire periphery.
  • Such a film for example made of aluminum or other materials, further slows the possible gas exchanges between the interior and the exterior, increases protection against ultraviolet rays, which is desirable when packaging certain sensitive products, and provides overprotection, that is to say an improvement in inviolability, sought in particular for the packaging of pharmaceutical products.
  • the capsule To facilitate the assembly, before the installation of the pouring and capping cap assembly on a bottle neck, of the cap, on the one hand, and of the pourer with guarantee band, on the other hand, after separate manufacture of these two elements, it is advantageous for the capsule to have an outer conical shape converging from the upper face towards the lower edge of the capsule. This cone shape simplifies the insertion of the capsule inside the guarantee strip from the inside return side of the latter.
  • the pourer comprising at least one annular skirt externally surrounding the neck and provided with a inner bead for hooking in an outer groove of the neck, said skirt has an extension extending downwards beyond the hook bead, to come to bear by its lower end on an outer shoulder of the neck. Said extension has several zones of reduced thickness in the form of vertical grooves.
  • the outer skirt of the pourer has internally, between said zones of reduced thickness, ramps between said extension and the bead d 'hanging.
  • the pourer and stopper cap assembly comprises a pourer 1 and a stopper cap 2, both made of plastic, for example polyethylene.
  • the pourer 1 comprises two concentric skirts 3 and 4, of generally cylindrical shape, namely a substantially smooth inner skirt 3 and an outer skirt 4 comprising an inner annular bead 5, about halfway up.
  • the pourer 1 is pressed onto the neck 6 of a bottle so that the inner skirt 3 penetrates inside the neck and that the outer skirt 4 externally surrounds the neck, the bead 5 snapping into an outer groove 7 bottleneck.
  • the two skirts 3 and 4 are joined by an annular connecting part 8.
  • the inner skirt 3 is extended upwards, beyond the connecting part 8, in the form of a pouring spout 9 whose upper annular edge 10 is curved outwards.
  • the outer skirt 4 has an extension 11 whose lower end bears against an outer shoulder 12 of the neck 6.
  • This extension 11 has several zones 13 of reduced thickness, distributed around the periphery.
  • the zones 13 of reduced thickness, only one of which is visible on the left-hand side of FIG. 1 are in the form of vertical grooves in the internal face of the extension 11.
  • ramps 14 are provided, between the zones 13 of reduced thickness, on the inner face of the extension 11, below the attachment bead 5, to facilitate the sinking of the pourer 1 on the bottle neck 6.
  • the capsule 2 is formed by a bottom 15 on which two concentric skirts 16, 17 project downwards, of generally substantially cylindrical shape.
  • the inner skirt 16 is intended to cooperate by forcing with the interior of the pouring spout 9, to ensure the sealed closure of the latter.
  • the outer skirt 17 of the capsule 2 is used for gripping the capsule 2 and a stop limiting the sinking of the inner skirt 16 in the pourer 9. To this end, the lower end of the outer skirt 17 carries, when the capsule is pushed in fully, on the connecting part 8 of the two skirts 3 and 4 of the pourer 1.
  • the outer skirt 17 of the capsule 2 has internally a cylindrical shape and externally a general frusto-conical shape converging from the bottom 15 towards the lower edge of the skirt.
  • the skirt 17 is formed from a thick upper part 18, from a thin lower part 19, and from a connection part 20 having a strongly frustoconical external shape.
  • the comparison of the left and right parts of FIG. 1 shows that vertical ribs 21 distributed around the periphery connect, on the external face of the skirt 17, the two parts 18, 19 with a smaller taper than that of the outer surface of the intermediate part 20.
  • These ribs 21 which constitute a sort of knurling facilitating the gripping of the capsule 2 give the latter a generally frustoconical outer shape.
  • the bottom 15 of the capsule 2 carries, on its upper face a short distance from its outer edge, an annular bead 22 which is located substantially in the extension of the part 19 of the skirt 17.
  • a removable security strip 23 is produced in one piece with the pourer 1. As shown in FIG. 2, the guarantee strip 23 extends around the entire periphery of the capsule 2 and has a weakening zone 24 and a tear-off tab 25 located on one side of the weakening zone 24, the free end of the tab 25 being connected to the strip 23 by a frangible connecting bridge 26.
  • the strip 23 is connected by its lower edge to the outer edge of the connecting part 8 of the pourer 1 by a thin peripheral connecting line 27 reinforced, in several places distributed around the periphery, by thicker bridges 28 (see part on the left and right part of figure 1).
  • the guarantee strip 23 extends from its connection zone (27, 28) to the pourer 1 upwards over the entire height of the capsule 2 and has, at its upper end, an inner return 29 which covers the outer edge of the bottom 15 of the capsule 2, the free end of the inner return 29 coming to bear against the shoulder formed by the annular rib 22 of the bottom 15 of the capsule 2.
  • the height of the rib 22 is equal to or greater than the thickness of the strip 23 at the location of the return 29. In this way, the return 29 is set back relative to the upper face of the bead 22, or at most flush with this upper face of the bead 22.
  • the internal return 29 of the guarantee strip 23 comprises several notches 30 distributed around the periphery.
  • the notches 30 are intended to give the return 29 sufficient elasticity to allow deformation towards the outside of the return 29 when the capsule 2 is pressed in on the pourer 1 provided with the guarantee strip 23.
  • the return 29 is deformed towards the outside by the external skirt 17, of generally frustoconical external shape, the return 29 expanding inwards to resume the shape visible in FIG. 1, that is to say for cover the upper outer edge of the capsule 2, when the latter is fully pressed, the lower end of the skirt 19 of the capsule 2 bearing against the connecting part 8 of the pourer 1.
  • the guarantee strip 23 has external ribs 31 which extend upwards the thick bridges 28 connecting the strip 23 to the pourer 1.
  • the pourer 1 has inside its internal skirt 3, a network of bars connecting a central rod 32 visible in FIG. 1 to the lower body of the skirt 3.
  • the purpose of this arrangement is on the one hand to regulate the pouring, by the pourer, of the liquid conditioned in the container equipped with the pouring assembly and closure cap, and on the other hand to simplify the injection molding of the pourer.
  • the injection is effected by the rod 32 (carrot) and the bars constitute supply channels for the entire mold.
  • a sheet 33 for example of aluminum or plastic, can be attached to the top of the capsule by being welded to the flange 29.
  • any attempted violation prior to tearing off the guarantee strip, whether at the pouring link 1 - bottle neck 6 or the capsule 2 - sealing strip link warranty 3, causes damage detectable to the naked eye (rupture of the lower part 11 of the outer skirt 4 of the pourer 1 at the location of the weakening zones 13, rupture of the warranty strip at the location of the weakening zone 24).
  • the pouring and closure cap assembly according to the invention provides perfect sealing and in particular prevents any passage of gas (air inlet or gas outlet, protective), hence an extension of the duration of possible conservation of the packaged product, in the case where, in addition to the sealed connection between the guarantee strip and the pourer, a sealed connection is also provided between the guarantee strip and the capsule (by welding the return 29 to the capsule 15 and / or by the use of an additional sheet welded on the return of the guarantee strip).
