Definitions

  • the invention relates to safety devices intended to be mounted on metal packaging so as to keep the packaging and its lid integral and watertight during transport and handling.
  • the invention applies in particular and more particularly to the transport of so-called dangerous materials within the meaning of the Transport Regulations. Mention may be made, among such so-called hazardous materials, of paints and other materials likely to contain solvents.
  • Patent application EP-A-0 246 783 describes, for example, a serrated ring intended to hold together a metal package and its cover.
  • the object of the invention is to produce a device which confers on a package mechanical strength and sufficient tightness to meet the requirements corresponding to those of a drop test and transport standards.
  • An object of the invention is to provide such a device which can be produced inexpensively and which is easy to place and remove.
  • Another object of the invention is to provide such a device which fits on traditional packaging and on their lids.
  • the subject of the invention is a plastic safety ring intended to hold a cover in place on a container of the paint can type, this container, substantially cylindrical, comprising at its upper part an annular rim which is attached on the outside to the side wall of the container by a crimping forming a bead which projects towards the outside of this side wall, the cover having on its periphery a groove open upwards, said safety ring having a cross section in substantially U-shape and comprising an internal crown, an external skirt and a ring connecting the internal crown and the external skirt by their upper part.
  • the external skirt consists of an annular element without a solution of continuity having an internal face provided at its lower part with a continuous rim directed towards the internal crown, this rim having a substantially conical lower surface flaring towards the bottom and an upper surface substantially perpendicular to the axis of the safety ring, the dimensions of the safety ring and its constituent elements being such that the safety ring can be placed on the upper part of the container with its lid, the internal crown being engaged in the groove of the lid with which it fills at least the major part, the ring of the ring covering the outer edge of the cover and the upper edge of the container, the outer skirt descending over the upper edge of the container, the continuous rim being engaged at the upper part of the container below the bead of crimping, this continuous rim being in permanent elongation because the inside diameter of the continuous rim is, before fitting the ring, less than the outside diameter of the side wall that this rim encloses.
  • a stepped projection protrudes from the concave face of the ring of the ring, on the side of the axis of the ring, so that when the ring is placed on a container, said projection presses on the periphery of the cover.
  • the safety ring advantageously includes dismantling means.
  • An advantageous form of these dismantling means comprises a projection which goes around said ring on the internal side, in the extension of the flat ring and a surface in the cover on which a tool can bear.
  • the dismantling means comprise at least one rupture initiation formed at the junction between the outer ring and the flat ring.
  • a hollow tab can extend laterally on the side of the outer ring, said tab being able to receive the blade of a tool for dismantling said ring.
  • the outer face of the outer skirt has, at its lower part, a tongue which extends radially outwards, this tongue being pierced with an orifice suitable for the insertion of a tool , such as a screwdriver blade, for dismantling said ring.
  • a tool such as a screwdriver blade
  • a protrusion forming an extra thickness goes around the external face of the outer crown.
  • Another object of the invention is a reinforced container of the paint can type, substantially cylindrical, comprising at its upper part an annular rim which is attached on the outside to the side wall of the container by a crimping forming a bead which projects towards the outside of this side wall, a cover having on its periphery a groove open upwards and a safety ring having a cross section substantially in the shape of an inverted U and comprising an internal crown, an external skirt and a ring connecting the internal crown and external skirt by their upper part.
  • the outer skirt of the ring consists of an annular element without a solution of continuity having an internal face provided at its lower part with a continuous rim directed towards the internal crown, this rim having a substantially conical lower surface s' flaring downwards and an upper surface substantially perpendicular to the axis of the safety ring, the dimensions of the safety ring and of its constituent elements being such that the safety ring can be placed on the part upper part of the container fitted with its lid, the internal crown being engaged in the groove of the lid of which it fills at least the major part, the ring of the ring covering the outer edge of the lid and the upper edge of the container, the outer skirt descending over the upper edge of the container, the continuous rim being engaged at the upper part of the container below the crimping bead, this continuous rim being in permanent elongation because the inside diameter of the continuous rim is, before fitting the ring smaller than the outside diameter of the side wall that this rim encloses.
  • the rim is extended by a groove capable of accommodating the throat of the cover, a seal being placed between the lip groove and lid groove.
  • the rim of the container lid is extended by a volute and the rim of the body by a loop, a seal being placed between the loop and the volute.
  • the peripheral groove of the cover is extended by a volute, a seal being placed between the volute of the cover and the flange.
  • One of the advantages of the invention is that it allows containers, which are otherwise standard, to successfully undergo the mechanical resistance tests imposed during the transport of so-called dangerous substances.
  • Another advantage of the device according to the invention lies in its high resistance to internal pressure in the container. This internal pressure is due in particular to solvent vapors and it can rise up to 100 kPa (1 kg / cm2) without posing any problem for the device.
  • Another advantage is that the containers can be reinforced only according to the requirements and constraints of transport and are therefore of modular cost.
  • Another advantage of the security device according to the invention lies in the fact that it makes the packaging practically inviolable. Indeed, it is not possible to remove the safety device without visibly damaging it.
  • Fig. 1 is a sectional view of a ring 1 according to the invention, made of plastic and mounted on a metal container 2, the body of which is closed by a cover 3.
  • This container has a side wall 4 which is connected to an upper rim 5 by a crimping 6 rolled outwards and forming a bead 7.
  • the upper rim 5 of the container 2 contributes to its rigidity and serves as a support for the cover 3.
  • the rim 5 forms a groove 8 in which, when closed, a friction groove 9 is formed, of corresponding shape formed at the periphery of the cover 3.
  • the end 10 of the rim 5, as well as the end 11 of the cover 3, is terminated by a stiffening volute.
  • the ring 1 which is placed on the container 2 already closed (for example under the effect of a press) (not shown), has three parts 12, 13, 14, seen here by the edge, whose arrangement in U is clearly visible: an internal ring 12 and an external skirt 13 which are connected on either side of a ring 14.
  • the face of the external skirt 13 facing inwards has a re-entrant flange 15 which extends all over its periphery.
  • the crown 12 engages by force in the grooves 8, 9 of the cover and the rim and ensures their maintenance in the event of impacts. during a possible impact, the presence of the crown 12 prevents the two grooves 8, 9 from crushing, which contributes to maintaining the integrity of an essential part of the closure device.
  • the re-entrant flange 15 is inserted under the bead 7 which forms the crimping.
  • the length of this rim 15 is less than that of the side wall 4, so that this rim 15 is in permanent elongation and encloses the side wall 4 of the container 2 under the bead 7.
  • a stepped projection 16 projects into the groove of the ring 1, ensuring pressure on the cover 3 below the level defined by the crimping 6.
  • An additional seal can be obtained by interposing between the cover and the container a seal 31, whether it is a separate seal of the o-ring type or a seal mounted in situ, for example between the end volute 11 of the cover and the rim 5.
  • the cover 3 is clamped against a loop 18 secured to the rim 5.
  • the throat of the cover ends in a volute 19 which is pressed against the projection 16.
  • the ring 1 is mounted on the cover 3, its inner ring 12 being forcibly mounted in the groove 8 of the said cover 3, and the re-entrant flange 15 is engaged under the bead 7 defined by the crimping 6 of the flange 5 with the side wall 4.
  • Fig. 3 is a perspective view of the ring 1 as a whole and clearly shows the ring 14, the crown 12 and the continuous skirt 13 extending on either side of this ring 14.
  • Fig. 4 shows an embodiment allowing easy dismantling of the ring 20 after use: a projection 21 goes around the ring 20 on the internal side, parallel to the ring, so as to allow the insertion of a tool 22 (such as a screwdriver) and the release of the ring 20 by a simple twisting movement from a fulcrum formed by the cover 3 itself.
  • a tool 22 such as a screwdriver
  • Fig. 5 is a schematic sectional view of a metal package 2 topped with its cover 3 and of a protective ring 23 with side tab 24.
  • This tab 24, placed at the outer periphery of the ring 23, allows the insertion of a tool 22 (such as a screwdriver) parallel to the axis of the container, to release the ring 20 from the container 2 on which it is mounted, by exerting on this tool 22 a simple or combined torsion.
  • a tool 22 such as a screwdriver
  • Fig. 6 is shown another embodiment making it possible to separate the ring 25 from the container 16 which it covers.
  • the ring 25 comprises, spaced along its length, interrupting primers 26 at the level of the external angle between the ring 14 and the skirt 13.
  • These primers 26 are of a width just sufficient for one to be able to insert therein the blade of a tool 22, such as a screwdriver, so as to be able to locally exert a breaking stress on the ring 25.
  • a continuous reinforcement bead 27 goes around the skirt 13 near its end.
  • Fig. 7 is a side view of the ring 25 of FIG. 6 clearly showing the incipient fractures 26 regularly arranged along the ring 25, at its upper part, and the reinforcing bead 27 at the end of the skirt 13, on the opposite face of the re-entrant flange 15.
  • Figs. 8 and 9 show, respectively, in plan and in section, another means of dismantling the safety ring (28).
  • This tongue 29 is provided with a central orifice 30 allowing the insertion of a tool 22 such as the blade of a screwdriver. This tool makes it possible to exert a twist on the ring 28 and to cause it to be dismantled.
