Definitions

  • the invention relates to a closure device for a container having a cylindrical opening.
  • a closure device for a container having a cylindrical opening comprising inner and outer closure members each comprising an end member and a skirt member, which closure members are rotatable in unison to release the device from an opening to which it is applied, in use, on substantially axial pressure on the outer member, and means to indicate that such operation of the device has been effected or attempted.
  • a closure device for a container having a cylindrical opening comprising inner and outer closure members each comprising an end member and skirt member, and first and second drive means, the first drive means being between the respective skirt members and being operative to rotate the closure members in unison in one sense only, the second drive means being associated with means biassing the inner and outer members axially apart and being operative to rotate the closure members in unision in the opposite sense only when pressure is applied, to the outer member in the axial direction sufficiently to overcome the pressure of the biassing means to move the outer member towards the inner member and the outer member is rotated in the opposite sense, and means to indicate that such operation of the device has been effected or attempted.
  • the indicating means may comprise a frangible part of the outer closure member. This provides a positive indication of such operation.
  • the frangible part may comprise a circular part such as a disc of the end member of the outer closure member.
  • the inner member may have a boss aligned with the disc and acting thereon to rupture a frangible connection by which the disc may be connected to the end member of the inner member.
  • the indicating means may comprise a colour indicator of such operation.
  • the inner closure member may comprise a seal for sealing in use the cylindrical opening to which the device is applied.
  • the seal may comprise a resilient flange extending from the end member of the inner closure member towards the skirt member thereof.
  • the flange may terminate short of the skirt member of the inner closure member.
  • the invention extends to a container having a screw-threaded cylindrical opening and a closure device as hereinbefore defined in which the inner surface of the skirt of the inner cylindrical closure member has a screw thread which mates, or can mate, with the screw-threaded cylindrical opening.
  • a safety closure device, for the externally screw-threaded neck of a bottle is hereinafter described, by way of example, with reference to the accompanying drawings.
  • FIG. 1 shows a longitudinal sectional view of the closure device
  • Fig. 2 shows the closure device in position on a container such as a drugs or pill bottle;
  • Fig. 3 shows an enlarged fragmentary part of Fig. 2; and Fig. 4 shows part of the device after opening.
  • the closure device 1 shown comprises inner and outer cylindrical closure members 2 and 3 each comprising respectively an end member 4 and 5 and a skirt member 6 and 7 and first and second drive means 8 and 9 .
  • the first drive means 8 being between the skirt members 6 and 7,
  • the second drive means 9 being associated with biassing means in the form of a resilient member or ring 10 which biasses the inner and outer members 2 and 3 axially apart (upwardly as viewed) .
  • the inner cylindrical closure member or cap 2 is smaller on its outer diameter than the inner diameter of the outer cylindrical closure member or cap 3 . so there is a gap 11 between the two caps in which the first drive means 8 is situated.
  • the first drive means 8 for turning the two caps 2 and 3 in unison in one sense to tighten the closure device 1 on the neck comprises four equally circumferentially spaced apart ratchets 12 on the outer (as viewed) surface of the skirt 6 and four driving dogs 13 equidistantly circumferentially spaced apart on the inner (as viewed) surface of the skirt 7 «
  • the second drive means 9 comprises eight equidistantly spaced apart sockets 14 carried by the outer surface of the end member 4 of the cap 2 and two diametrically opposed dogs 15 which are of generally triangular section with a flat l ⁇ and which project from the inner surface of the end member 5 of the outer cylindrical cap 3-
  • the ring 10 is of less diameter than the diametrical spacing of the drive dogs 15 and has greater height that those dogs 15 so that the inner and outer caps 2 and 3 are spaced apart with the drive dogs 15 out of engagement with the sockets 14-
  • the outer surface of the end member 4 of the cap 2 has an upstanding boss 17 which is axially aligned with a frangible part 18 of the end member 5 of the cap 3 .
  • the frangible part l8 being in the form of a circular disc which is spaced from the surrounding part of the end member 5 and is connected therewith by a frangible connection in the form of two diametrically opposed lugs 19 and 20.
  • the boss 17 and disc l8 form means to indicate that operation of the closure device 1 to remove it rom a cylindrical opening has been effected or attempted.
  • the inner surface of the end member 4 of the cap 2 has a seal
  • the inner cap 2 is made of plastics of a different colour from that of the cap 3 « Thus the cap 2 may be red and the cap 3 white.
  • the two caps 2 and 3 are force-fitted together so that they assume the assembled condition shown in the drawings.
  • OMPI cap springs past a circumferential lip 23 on the outer cap 3 on assembly and anti-removal means in the form of four detents 24 on the inner cap to prevent it from springing out of the outer cap 3 past the lip 23 after assembly. 5
  • a bottle 26 such as a medicine bottle (Figs. 2,3) the closure device 1 is offered up to the neck 25 and the screw threads engage when the outer cap 3 is turned in one sense, clockwise, to effe This turning causes the drive dogs 13 to engage 0 the free edges of the ratchets 12 so that both inner and outer caps 2 and 3 turn in unison in the tightening direction.
  • the drive dogs 13 merely click over the ratchets 1 , which are resilient.
  • the 5 closure device 1 remains firmly in place on the neck 25-
  • the inner cap 2 now turns with it so the two can be rotated in unison and removed from the neck.
  • the resilient ring 10 urges the two caps 2 and 3 axially apart again so that the drive dogs 15 and sockets 14 disengage, ready for re-assembly of the 5 closure 1 with the neck as described.
  • the seal 21 provides a comprehensive seal of the opening 27 as it can flex to accommodate any shape of mouth of the opening, including where t the outer edge 28 thereof is angled or curved towards the centre.
  • the boss may have a diameter equal to or less than the diameter of the disc.
  • the boss and disc may be of different configurations, for example, hexagonal and circular respectfully.
  • the frangible connection may comprise a relatively thin membrane rather than the two lugs 19 and 20 shown.
  • the lug may be the only part which is
  • the closure device referred to may be made to fit any standard container or bottle. No special container or bottle is required.

Abstract

Dispositif de fermeture de sécurité (1) pour un conteneur. Après enfoncement initial du couvercle extérieur (3) du dispositif lorsqu'il est placé sur le col d'un conteneur, la surface inférieure (comme illustrée) du disque (18) porte sur la surface supérieure (commu illustrée) du renflement (17) dont le diamètre est supérieur à celui du disque (18) mais inférieur à celui de l'ouverture circulaire pratiquée dans l'élément terminal (5) dans lequel est placé le disque. Le renflement (17) rentre dans l'ouverture, portant sur les ergots (19 et 20) et les brisant, la pression étant considérablement accrue à l'endroit où les ergots portent sur le bord tranchant de l'ergot au passage de la surface supérieure à la paroi de délimitation de celle-ci. Le disque (18) est alors libéré et, lorsque les ergots (19 et 20) se brisent, tend à jaillir hors de l'ouverture et du dispositif de fermeture, laissant ainsi un trou circulaire. Cela indique que l'on a effectué ou tenté d'effectuer l'opération consistant à retirer le dispositif du conteneur; l'effet est encore renforcé par la couleur rouge du renflemement se montrant par l'ouverture et contrastant avec le blanc du couvercle extérieur (3). Un joint (21) du dispositif (1) garantit une large étanchéité de l'ouverture puisqu'il peut se plier pour s'ajuster à n'importe quelle forme d'orifice de l'ouverture, même si le bord extérieur de celle-ci est incliné ou recourbé en direction du centre.
