Definitions

  • the present invention relates to improvements made to tamper-evident closures made of thermoplastic material and comprising a threaded capsule and a guarantee ring suitable for snap-fitting in a groove in the neck of a container.
  • the shutters of the type in question have a series of bridges connecting the capsule and the ring which break when the capsule is unscrewed.
  • the cross-section of the bridges considered must therefore be small so that their rupture is effective as soon as the capsule is unscrewed.
  • the capsule is rotated by a unscrewing device which resiliently extracts the inner cord of the guarantee ring from the groove which made it possible to mold it. It follows a significant traction which is cashed by the connecting bridges. As they have a reduced section, there are often untimely ruptures thereof so that the shutter must be discarded. It is therefore necessary that the release temperature of the parts is very carefully monitored because the release must be carried out when the material is still hot enough so that the extraction of the locking cord from the guarantee ring does not require a force of too much traction.
  • Swiss patent 444,696 a metal capsule is described in the skirt of which incisions are made which determine two tabs whose ends are partially in abutment against one another. It goes without saying that this embodiment cannot be applied to a molded plastic capsule with a view to solving the problem posed above.
  • the improvements which are the subject of the present invention aim to remedy the aforementioned drawbacks and to allow the production of a shutter comprising a threaded capsule and a lower guarantee ring whose connecting bridges cannot flame, and therefore do not do not break under the effect of the axial force applied to the ring in the direction of the capsule.
  • the free lower edge of the skirt of the capsule has support stops located in the immediate vicinity connecting bridges so that during the installation of a shutter thus arranged on the neck of a bottle, these are the abutments which work in compression instead of the connecting bridges.
  • the shape of the stops is such that it allows the shutters to be removed from the mold, that is to say it has stripped faces in the direction of the outside.
  • the ring is provided with a system capable of causing it to break when the user so desires.
  • a shutter assigned to the general reference 1 and which comprises a threaded capsule 2 and a guarantee ring 3 connected by connecting bridges 4 ensuring inviolability.
  • a shutter well known in the practice is revealed in particular in prior patent 70 00832.
  • Its cap is intended to be screwed onto the thread 5a of the neck of a container such as a bottle 5 (fig. 2).
  • the inner face of the ring 3 has a cord 3a which projects in order to snap elastically under a shoulder 5b determined by a bulge 5c formed at the periphery of the neck below its thread 5a.
  • a matrix 6 is used in which this shutter is engaged, and which is integral with the head of the capping machine.
  • This head is first of all moved axially in the direction of the bottle 5, then it is subjected to a rotational movement which causes the cap 2 to be screwed onto the thread 5a of the bottle 5.
  • the cord 3a of the ring 3 comes cooperate with the top of the bulge 5c which causes a significant axial force between this ring and the capsule 2 so that the connecting bridges 4 which join the two considered elements of the shutter undergo significant buckling often leading to their rupture.
  • each stop 7 which are in the form of pins with a triangular cross section and which occupy the thickness of the lower free edge 2a of the capsule 2.
  • the top of the triangular cross section of each stop 7 is located outside so as to facilitate demolding, so that the stops are in the form of a prism with a side wall in relief. In reality, the vertical edge of each stop is rounded in order to be less visible.
  • the height of the stops 7 is slightly less than that of the bridges 4, a clearance of 0.4 mm being for example provided for a height of said bridges of 1 mm. But of course this game is not necessarily of this importance; it suffices for it to allow the stops 7 to be molded so that their free ends are separated from the ring 3.
  • each stopper 7 Given the section of each stopper 7, it is possible to reduce as much as possible that of the connecting bridges 4 since they take almost no effort during installation. The considered section of the connecting bridges is therefore only determined by their tensile strength developed during the release of the bead 3a.
  • connection bridges 4 of which are not subjected to any force during its positioning on the threaded neck of a container, their cross section then being sufficiently small to ensure their immediate rupture from the start of the unscrewing of the capsule.
  • a shutter according to the invention the guarantee ring 3 of which includes a tearing system.
  • This system is produced in the form of a shoe 8 of triangular shape in profile in plan and which is joined to the ring 3 by means of a radial tab 3a of this ring.
  • This comprises a thinned zone 3b leading to the origin of the tab 3a and which constitutes a solution of continuity of said ring (fig. 6).
  • shoe 8 is provided with an oblique face 8a extending centrifugally from the end of the tab 3a secured to the ring 3.
  • the shoe 8 can easily be tilted according to the arrow F in FIG. 7 so that its place 8a comes to bear against the outside of the ring 3 opposite the zone 3a by deformation of the tab 3b.
  • a significant traction is exerted on the thinned zone 3b due to the leverage effect so that one easily breaks said zone. Consequently, it is very easy for the user to eliminate the ring 3 after opening the capsule.
