Definitions

  • the object of the invention is a tamper-evident device for a container, the neck of which is closed by a screw cap.
  • Flexible tubes are known, the plastic neck of which is closed by a plug incorporated in the form of a blind tube.
  • the open end of the blind tube is connected to the end of the neck by a zone of less resistance which can easily be torn off by twisting.
  • the closed end of the blind tube has an outside diameter corresponding to the inside diameter of the opening made at the end of the neck by rupture of the blind tube. It is thus possible to close the neck temporarily by turning the cap over and pushing the closed end of the blind tube.
  • Capsules are also known which are screwed on with a frangible peripheral band or flange along a line of least resistance.
  • Tamper-evident devices consisting of a thin aluminum seal glued to the opening of the neck. This cover must be torn off or fractured before withdrawing the contained product. This device has the disadvantage of poor visualization. It requires unscrewing the protective cap and carefully examining the seal to check the condition of the seal. It obliges the container manufacturer to carry out an additional operation of placing and gluing the thin seal before screwing on the cap.
  • Thin plastic lids are also known which are made in one piece with the neck also made of plastic, but it is not possible to obtain plastic lids of very precise thickness, and therefore always of sufficiently small thickness.
  • Plastics are elastic materials, not very malleable. The opening of such lids requires a tool.
  • the object of the present invention is a tamper-evident device for a container, the neck of which is closed, by a screw cap, this neck being initially closed by a blind tube in the extension of the neck.
  • the open end of this blind tube is connected to the end of the neck by a weakened area.
  • This weakened area has an outer diameter smaller than that of the blind tube.
  • the blind tube is threaded according to a thread with the same axis and the same
  • the threads of the blind tube correspond to those of the neck, so that the neck and the capsule are simultaneously screwed into a double-tapped capsule.
  • the capsule in addition to its main thread complementary to the thread of the neck, has an auxiliary thread of the same axis and not even (p) complementary to the thread of the blind tube.
  • the distance between the bottom of the capsule's auxiliary thread and the lower end of its main thread is less than the distance between the end of the blind tube and the bottom of the main thread of the neck while the depth of the auxiliary thread is less than the height of the blind tube.
  • the capsule when the capsule is screwed simultaneously onto the blind tube and the neck, it is the bottom of the auxiliary thread of the capsule which abuts, first, on the closed end of the blind tube, before the screwing of the capsule on the neck is complete.
  • the blind tube is then blocked at the bottom of the capsule. If screwing is continued, the blind tube is driven by the capsule and sinks into the
  • the weakened zone connecting the blind tube to the end of the neck breaks quickly by shearing: it suffices to continue screwing for about 1/3 of a turn.
  • the weakened zone of the blind tube is generally given a thickness of about 1/3 that of the wall of the blind tube. This weakened zone corresponds to a peripheral groove reducing the thickness of material at the connection of the blind tube with the neck.
  • the outside diameter of the weakened zone is thus less than the diameter of the tube, which allows it to penetrate slightly into the neck during the sinking-shearing operation when the cap is continued to be screwed.
  • the maximum distance between the bottom of the auxiliary thread and the bottom of the main thread of the capsule can vary depending on the elasticity and brittleness of the materials. It is generally at least half a thread pitch less than the distance between the end of the blind tube and the bottom of the main thread of the neck. This allows a screwing of at least 1/2 turn after the bottom of the capsule has come up against the end of the blind tube.
  • the depth of the auxiliary tapping of the capsule must also be at least 1/2 pitch less than the height of the blind tube so that the bottom of the auxiliary thread does not come up against the end of the neck.
  • the diameter of the blind tube is generally of the order of half the diameter of the neck.
  • Such devices are easily produced in various plastics such as P.C.V, polyethylene, polypropylene; they are particularly suitable for making flexible metal or plastic tube heads.
  • the attached drawing shows, in axial section, a flexible polyethylene tube head mounted by snap-fitting or by force on a flexible tube body (1) made of aluminum.
  • the head of the flexible tube (1) has at its upper part a threaded neck (2) of conventional shape intended to be closed by a capsule (3, screwed by means of a tapping (4).
  • the neck (2) of the head is extended by a blind tube (5) the outside of which is threaded with a thread with a diameter smaller than that of the neck (2), but similarly and whose threads are in agreement.
  • This blind tube (5) is connected to the end of the neck (2) by a weakened zone (6) of reduced diameter, this both with respect to the outside diameter (D) of the neck (2) and to the diameter (d) of the blind tube (5).
  • This reduction in diameter corresponds to a peripheral groove at the connection of the blind tube (5) with the neck (2).
  • the capsule (3) itself comprises two complementary coaxial threads each with a thread of the head.
  • the main thread (4) of the capsule allows it to be screwed onto the neck (3).
  • the auxiliary thread (7) has a diameter (d) corresponding to that of the thread of the blind tube (5); its depth (1) is less than the height (h) of the blind tube (5).
  • the diameter (D) of the main thread (4) corresponds to that of the neck thread.
  • the distance (L) between the bottom (8) of the auxiliary thread (7) and the bottom of the main thread (4) is less than the distance (H) between the end of the blind tube (5) and the bottom (9) the main thread of the neck (2).
  • the screwing is slightly forced; it can continue on the neck (2) by the thread (4) but not on the tube (5) which abuts on the bottom (8).
  • the tube (5) is driven by the helical displacement of the capsule (3), which continues to be screwed onto the neck (2).
  • the weakened zone (6) sinks slightly into the end of the neck (2) by bending and undergoing a torsional force. The weakened zone (6) breaks easily by shearing without having to continue screwing more than about 1/3 of a turn, thus creating the desired perforation at the end of the neck (2).
  • H> L that is, in practice: H - L ⁇ P 2; at the same time as h - 1.
  • the capsule (3) for d L s reasons of aesthetics or ease of stacking, comprises a skirt (10) of the same external diameter as the flexible tube (1), it is important to provide a clearance ( E) between the bottom of the skirt and the shoulder of the flexible tube.
  • E clearance between the bottom of the skirt and the shoulder of the flexible tube.
  • the head of the tube with its capsule (3), in place is mounted on the flexible tube (1).
  • the tube (1) is filled from below with consumable product.
  • the bottom of the tube (1) is sealed immediately after filling and shipped to a distributor. It is easy to see from the distributor that the tube has not been fraudulently opened by simply checking the clearance (E) between skirt (10) and tube head or the clearance (H - L) between the bottom of the main thread ( 4) of the capsule and the bottom (9) of the nrincinal thread of the neck, without even have to completely unscrew the capsule.
  • the capsule can also be completely unscrewed without in any way damaging the tamper-evident device.
  • the head of the flexible tube, with its neck (2) and its blind tube (5) are made of polypropylene as well as the capsule (3).
  • the tube (1) is made of aluminum.
  • the tube (1) could equally well be made of plastic or of a metallo-plastic complex.
