Definitions

  • This invention is concerned with the provision of an improved tamper-resistant and tamper-evident container body and closure assembly.
  • the invention also includes an improved closure for application to the neck of a container body.
  • a standard form of container body has a mouth at the top and an external annular bead around the neck of the body below the mouth and such container bodies are hereinafter referred to simply as standard container bodies and the external bead around the neck is hereinafter called a neck ring.
  • a closure comprising a cap part with a top and a depending skirt and a tamper-resistant safety band connected to the skirt by frangible means characterised in that the tamper-resistant band is provided with a plurality of windows hereinafter simply called openings into which inwardly and upwardly inclined resilient lugs formed on the band project in such a way that when the closure is first applied to the neck of a standard container body the lugs are deflected so as to pass over the neck ring on the body and then, due to their resilience, the lugs snap back inwardly to their original position so that the upper end or the top of each lug is disposed below the lower surface of the neck ring.
  • a safety band which incorporates all the break nibs and driving ratchet/teeth/dog features on its uppar part with a smooth interior while the locking lugs, which may be formed with the same pair of splits, are on a lower part.
  • the locking lugs preferably consist of 2 or 3 pairs of lugs angled inwards and upwards from near the bottom edge of the break ring skirt and adapted to bend readily out of the way when passing the thread and/or neck ring of the container.
  • the lugs will work like a spring and revert to their original horizontal top edge so that they become locked beneath the horizontal 'roof' above them formed by the neck ring and no amount of 'fiddling' will move all the lugs clear of the neck ring, and the ring must break off whilst unscrewing the closure.
  • the precise shape of the lugs is not important and they may be produced using mould side wall openings and the shape of the opening is not important either. Suffice to say that the openings may be formed by 'conventional splits' in e.g. one, two or three opposing pairs.
  • the lugs preferably have a 'radial' arrangement in plan view simply for ease of application to standard container bodies despite the fact that the lugs are preferably formed by plain opposing splits meeting an inner core pin at 180 to each other.
  • each opening is slender, so that each lug can swivel readily about its pivot point. Otherwise, it will be appreciated that the lower edge of a lug may jam against the neck ring as the lug passes the ring whilst swivelling.
  • the closure has a cap part 1 with a top 2 and a depending skirt 3, the lower edge of which is connected by frangible tongues 4 to the upper edge of a tamper-­resistant band 5.
  • Teeth 6 are provided on the lower edge of the skirt 3 for engagement with teeth 7 on the upper edge of the band 5 to push the band 5 round with the cap part 1 when the closure is being screwed on for the first time.
  • the cap part 1 has an internal screw thread 8 for engagement with an external screw thread 9 on the neck of an associated container body.
  • the band 5 is provided with openings 10 in the lower part 14 of the band 5, see e.g. Figure 1.
  • An inwardly and upwardly inclined lug 12 is formed on the band 5 along the lower edge 13 of each opening 10 and each lug 12 may be shaped as shown to avoid sharp pointed corners that might hinder correct positioning of the lugs as the closure is being screwed on.
  • the closure In operation the closure is initially screwed down on to a filled container body until the lugs 12 on the band 5 engage with the neck ring 11 on the container body. Further screwing on causes the resilient lugs 12 to be deflected from their inclined position into a substantially vertical position as they move pas the neck ring 11. Finally as soon as the top of each lug 12 has moved past the bottom of the neck ring 11 each lug snaps back into its normal inclined position as shown in Figure 1, so that each lug 12 then projects into the associated opening 10 with the top of each lug 12 immediately below the neck ring 11. The closure is now in its tamper-resistant position because the closure cannot be removed from the container body without mutilation of the lugs and/or other parts of the closure.
  • a push on, push off cap may also be provided in accordance with the invention in which case on removal of the closure, the band 5 would be separated from the cap part 1 by breaking of the frangible nibs which would make it immediately evident that tampering or opening had occurred.
