Definitions

  • the invention relates to the field of closures fixed in an inviolable manner on the neck of a container.
  • Plastic opening capsules are known, the base or strain of which is fixed to the plastic neck of a tube typically by snap-fastening, this base comprising a sealing means from the inside of said neck, for example a penetrating crown. with forcing inside this neck.
  • This base is fixed to the neck by screwing or simple snap-fastening, of poor inviolability.
  • a cap comprising means of axial interlocking by force of a tamper-evident seal which overcomes the neck of a container.
  • nesting means are radial fins of longitudinal notching made of plastic material harder than that of said cover, or fins of longitudinal relief reliefs of the cover.
  • the Applicant has sought to develop a closure fitting the neck of a container comprising increased safety fixing means and is concerned with the adaptation of such means to the case of an opening capsule and a neck. with tamper-evident seal.
  • the subject of the invention is the assembly of a closure and a container with a neck, said closure and said container comprising complementary latching means, characterized in that said neck comprises a first latching means and below a second latching means consisting of a stop ring, said first latching means and said stop ring having between them a groove recessing several local reliefs of number greater than or equal to 3 each having at least the same side to the left or to the right a lateral bearing edge of the same inclination relative to the axis of said neck, the interior of said closure having local reliefs which engage in said groove and after possible rotation of said stopper cooperate simultaneously with said bearing edges of the reliefs of said groove by causing a downward movement consisting of or near a translation of said stopper and its snap-in below said stop ring .
  • the closure can then rotate freely around the neck.
  • the latching means inside the plug typically a skirt
  • the local reliefs which also play a role in driving in plugging beyond the stop ring.
  • each of these reliefs is housed at random in the throat of the neck, either against a portion of local relief of the neck itself recessed in this groove, or in an interval between local reliefs.
  • the position thus obtained is highly inviolable, it applies to various closures fixed on the neck of a container, whether they are associated with a separate sealing means or not, and to cut, pierce or open for the delivery of the content product.
  • the local reliefs cooperate by sliding simultaneously, which implies in practice and preferably that they are regularly spaced, these conditions ensuring good maintenance plugging along the axis of the neck.
  • the number greater than or equal to 3 and preferably odd of the local reliefs of the neck allows a good balancing or maintenance of the blockage in any descent position.
  • the odd numbers greater than or equal to 3 thus preferred indeed provide better axial stability than the even numbers, thanks to the constant diametrical asymmetry of their bearing zones. (no small tilting effect).
  • the local reliefs of the neck have support edges on the left and on the right, said local relief reliefs cooperating either with said support edges on the left, or with said support edges on the right according to the direction of rotation. clogging.
  • the bearing edges of said local reliefs of the annular groove of the container and of the interior of the stopper are preferably respectively perpendicular to their surfaces. These are then small abrupt lateral edges of these respective local reliefs of the throat of the container and of the internal surface of the stopper, the contacting of which causes a downward reaction which lowers the stopper.
  • the local reliefs of each surface are spaced around the longitudinal axis of the neck and of the stopper, their respective bearing edges being at the same level relative to this axis so as to simultaneously fulfill their role of driving down the capping.
  • the bearing edges of the local reliefs of the neck preferably regularly spaced as already indicated and whether they are on the left or on the right, have an inclination preferably between 30 and 60 ° and more preferably between 42 and 48 ° by relative to the axis of the neck, the support reliefs of the closure having edges cooperating with said support edges of the neck and of the same inclination as these support edges, said local reliefs of the closure also being spaced and being in number equal or submultiple of the number of said local reliefs of the neck, therefore "equal" in the case where the number of these reliefs of the neck is a prime odd.
  • the stop ring has an outside diameter 0.2 to 0.6 mm larger than the outside diameter of the first latching means, and that the local reliefs carried by said groove are set back from 0.2 to 0 , 5 mm to the radius with respect to the stop ring and set back 0.1 to 0.3 mm with respect to said first latching means.
  • the stop ring can be continuous or have discontinuities preventing a rise in the internal reliefs of the plugging by sliding.
  • the portion of the stopper comprising its so-called local reliefs, which cooperate with local reliefs in the throat of the neck to produce the descent of the stopper, is an annular crown 0.6 to 1 mm thick in plastic material, so to be sufficiently deformable to facilitate the two snaps of its local reliefs.
  • the stop ring is discontinuous and comprises pairs of sectors or portions allowing the passage down between these sectors of the local reliefs of the blockage, this passage being made with a local forcing on one of these sectors, the descent of the blockage is thus greatly facilitated (driving torque divided by 2 to 3).
  • a provision which allows such a result and further prohibits any rise in local reliefs of the interior of the blockage is as follows: the sectors of each pair of the stop ring respectively have opposite an edge substantially parallel to the edge of lateral support which surmounts it and one end thinned by an oblique edge, typically also substantially parallel to said lateral support edge, the distance between the lower ends of these edges of the two sectors being less than the minimum overall width of a said relief corresponding to the blockage.
  • the local forcing of this relief to descend through the insufficient gap between these two sectors takes place by elastic deformation downwards of the raised part of said thinned end and by local overlap of this thin deformed part.
  • the closure is an opening capsule provided with a base or strain
  • this strain comprising said latching means which are reliefs cooperating with the reliefs of the throat of the neck , this neck being surmounted by a tamper-evident seal
  • the opening part of the capsule comprising means acting on said seal for its cutting or breaking and its insertion into the neck during the downward translation and the latching of said strain under said stop ring.
  • said means acting on the cover preferably force fit the cover, so that the cover remains fixed in the capsule during its opening and payment of the product contained.
  • These means for force-fitting the cover are then typically either longitudinal fins inside the capsule fitting between longitudinal reliefs of the cover, or else longitudinal radial fins for notching the cover, as known by the two documents cited at the beginning of this description.
  • the plastic material of the capsule is harder than that of the cover to allow the notching, and preferably also in the case of nesting fins / reliefs to obtain a permanent tightening.
  • the cover in order to facilitate the insertion of the capsule and to further reduce the corresponding effort, for the cover to have longitudinal reliefs 2 to 4 times more numerous than the notching fins of the cover and below these longitudinal reliefs a smooth notching portion of lower height than that of said reliefs.
  • the beginning of the insertion of the fins is done easily and without indexing, randomly striating the narrow longitudinal reliefs of the cover, then the notching crossing the smooth portion which secures the cover and the capsule is of duration and effort relatively weak.
  • the cover comprises a recessed portion preceding an annular cup which serves as a stop for the filling of the neck with said torn cover and then retained in the opening part of the capsule.
  • the position just snapped on is preferably the delivery position, the seal by the cover being preserved by not breaking it.
  • the capsule For the opening, the capsule must be rotated by a variable angle but always less than 120 °, in a marked direction or in any direction, and when the capsule is pushed in by the mechanism already described the cover is torn by shearing and it sinks into the neck. If the rotation triggering the insertion is too low to completely tear the cover, the low rotation which accompanies the descent of the capsule by cooperation of the local reliefs of the invention and this descent itself leads to complete tearing and depression of this seal.
  • the means of the capsule acting on this cover are means of progressive knockdown of folding of this cover inside the neck.
  • the capsule is then preferably made of a harder material than this cover, for example of suitable plastic. Its opening part can be opened in the delivery condition without breaking the cover.
  • FIG. 1 represents an assembly according to the invention in the position of first click-in, in axial section.
  • Figure 2 is a diagram of local reliefs of the same assembly cooperating in the invention.
  • Figure 3 is a diagram of the portions of said assembly cooperating for the insertion and latching, in axial section.
  • Figure 4 shows the same assembly in the final driving position, in axial section.
  • FIG. 5 represents a second assembly, the neck and the cover of which are made of low-alloy aluminum, in axial section.
  • Figure 6 is a diagram of local reliefs and the discontinuous stop ring of a third assembly.
  • FIG. 7 is an enlargement of this diagram, the blockage having just undergone the second snap-fastening.
  • FIG. 8 shows the neck of the third assembly and part of its capsule, in axial half-section.
  • FIG 1 we see a tube 1 with neck 2 in HDPE (high density polyethylene) surmounted by an opening capsule 3 in PP (polypropylene) comprising a stump or base 4 and an opening part or cover 5 which can pivot by a hinge at 6 with respect to this base 4.
  • the neck 2 whose end orifice 7 has a diameter of 7.5 mm is surmounted by a tight seal 8 connected to the inside of the neck by a narrow tearable portion 9 0.2 mm thick.
  • the cover successively comprises an externally curved annular skirt 10 with an outer sealing diameter greater than 0.2 mm than the diameter of the orifice 7, then an annular cup 11 with an outer diameter 10 , 5 mm serving as a stop for the future insertion of the cover 8 into the orifice 7, and also serving as a safety stop for mounting the cover in the cover 5, then finally a cylindrical portion 12 of height 5 mm and with an overall diameter of 8.8 mm, having longitudinal reliefs 24 around its periphery.
  • the neck 2 carries 4 mm below its orifice 7, at the lower end of an inclined outer surface 14 of increasing diameter, a latching relief 15 in the form of a rib 15 with an outer diameter of 14 mm and a horizontal annular underside 16 surmounting a recessed cylindrical portion 17 with a diameter of 12 mm and a height of 2.5 mm.
  • This recessed portion 17 is followed by a stop ring. 18 with a diameter of 14.4 mm greater than that of the snap-fit relief 15.
  • the annular reliefs 15 and 18 and the recessed portion 17 delimit an annular groove 19 with a depth of 1 mm ( Figures 1 and 2).
  • annular groove 25 of height 2.7 mm intended for the latching of the local internal reliefs 13 of the stump 4 of the capsule 3 at the end of insertion (local reliefs 13 described below).
  • the opening part or cover 5 of the capsule 3 comprises a central tube 26 open at its two ends, its inner surface 27 of diameter 8.9 mm carrying radial fins 28 interlocking with forcing between the longitudinal reliefs 24 of the cover 8. It also includes an intermediate tube 29 which snaps into place with little effort in the stump or base 4.
  • This strain or base 4 comprises a central cylindrical portion 31 internally carrying the three local snap-on reliefs 13 of thickness 0.8 mm, height 2.3 mm and inside diameter of the envelope at rest 13 mm, each of these local reliefs 13 being of reverse trapezoidal shape with respect to the trapezoidal reliefs 20 of the groove 19, with lateral edges 32 and 33 inclined at 45 ° with respect to the axis 23, and being able to be opposed respectively to edges such as 22 and 21.
  • the lower portion 34 of the central portion 31 improves the centering of the insertion operations of the capsule 3, it is deformable transversely to facilitate the crossing of the annular snap reliefs 15 and 18 by the local reliefs 13 that it carries. Its thickness here is 0.7 mm, and in the general case from 0.6 to 1 mm.
  • the strain 4 also comprises an oblique intermediate portion 35 comprising a zone 36 for latching the tubing 29 of the opening part 5 and a rigid outer skirt 39 fitting with a clearance of 0.5 mm in diameter an annular crown 37 carried by the 'shoulder 38 of the container, this from the first click (crossing of the relief 15).
  • the first snap-fastening of the three local reliefs 13 of the strain 4 in the groove 19 is easily obtained, thanks to the conical entry 14 of the neck 2 and to the deformability of the annular crown 34 (FIG. 3) carrying these reliefs 13.
  • the FIG. 3 makes it possible to distinguish the important points for the penetration, the portions concerned of the neck 2 and of the strain 4 being shown apart for greater clarity.
  • the reliefs 24 and the fins 28 of the cover 8 and of the opening part 5 of the capsule 3 have started to interpenetrate, the cover 8 being immobilized in rotation relative to this capsule 3.
  • the outer skirt 39 already fits the annular crown 37 of the shoulder 38 of the container, preventing a possible tilting of the capsule 3 during the delivery operations.
  • the container is a tube 40 made of 99.5% purity aluminum comprising the characteristics of the invention, the local reliefs being obtained by traditional shaping operations.
  • the cover 41 has its circumference 42 thinned to facilitate cutting.
  • the insertion of the hard plastic capsule between the initial locking of the local reliefs 13 below the relief 15 and the final latching of these reliefs 13 below the annular stop relief 18 and in the groove 25 is accompanied by a knockout of the cover 41 and a drawdown of a at least part of this cover 41 inside the neck 2.
  • the opening part 5 of the capsule has an edge inclined at an edge 42 and a bearing edge 43 operating the folding down of the cut part.
  • the local reliefs of the neck are also spaced like the local reliefs 13 of the capsule.
  • the third assembly includes, like the first, a HDPE tube 45 and an opening capsule in PP of which only a local relief 13 snapping successively into the annular grooves 19 and 25 appears in FIGS. 6 and 7.
  • FIG. 6 which is an unrolled external view of the annular groove 19 and of the interrupted stop ring 180 which delimits this groove, said local relief 13 from the inside of the stump or base of the capsule y being shown after it clicks into the groove 19 for the purposes of the explanation, the retaining ring 180 comprises spaced sectors 181, 182 and 183.
  • the pair of sectors 181 and 182 has vis-à-vis an edge 220 parallel to the edge 22 of the local relief 20 of the tube 45 and an end 184 thinned in point by an oblique edge 185 substantially parallel to this same edge 22.
  • the thickness or height of the interrupted rod 180 along the axis of the tube is 0.7 mm and its radial width is, as for tube 1, 1.2 mm.
  • the distance "d" between the lower end 221 of the edge 220 and the lower end 186 of the oblique edge 185 is 2 mm, it is less than the minimum overall width "l" of the local relief 13, which is here the length of its upper edge 130.
  • This relief 13 cannot therefore cross sectors 181 and 182 of the stop ring 180 in the opposite direction once it has snapped into the lower groove 25 (fig. 7).
  • This principle also makes it possible to obtain a partial engagement in raising the local reliefs 13 of the capsule without it being possible to cross the sectors of the stop ring.
  • FIG 7 there is shown the elastic deformation of a portion 187 of sector 182 including its thinned end 184, this portion 187 being lying and overlapped by a portion of the local relief 13 harder.
  • This relief 13 having crossed the stop ring by sliding along the edge 220 and on the portion 187, this portion 187 straightens up as indicated by the arrow 188 and it will prevent with the other sectors any rise in the blockage.
  • the cover 8 in PE-HD carries 36 small reliefs or longitudinal teeth 80, 1.8 mm high, laterally, easy to cut by the 12 longitudinal notching fins 240 carried by the central tube 26 of the opening part 5 of the capsule 3.
  • Below the reliefs 80 there is a smooth portion 81 of height 1.2 mm and of the same overall diameter 8 mm as the longitudinal reliefs 80.
  • the fins 240 are in the process to easily score the reliefs 80 or sometimes to insert therein, which produces an anti-rotation fixing of the capsule 3 on the cover 8 and a centering of the depression.
  • the set of means 80, 81 and 82 located above the cup 11 gives a much easier start to depress the capsule.
  • the opening torque of the tube of the 3rd assembly is divided by 2.5 to 3 and is typically from 0.4 to 0.5 Nm
  • the invention applies to closures attached to the neck of a container and in particular to stub capsules called service capsules, the neck being provided with a tamper-evident seal.
