Definitions

  • This invention relates to an improved closure and to a container/closure assembly including such a closure. It is well known to provide a child-resistant closure that screws on to a conventional bottle neck but can only be removed by pressing down the outer shell whilst unscrewing. We have now found that a new danger exists where closures with child-resistance only are used with products that are vulnerable to tampering.
  • An object of the present invention therefore is to provide a closure which is both tamper-resistant and child resistant.
  • a closure for closing the mouth of a container having a screw neck finish comprising an inner part adapted to interengage with the screw neck of the container, an outer part to be applied over the inner part when in position on a container and including a depending skirt connected to anchor means by tearable or frangible means, and drive means on the inner and outer parts of the closure which are interengageable with one another in use to allow the inner part to be unscrewed from a container only once the anchor means has been separated from the depending skirt and only by axial movement relative/between the outer and inner parts during unscrewing whereby the closure is tamper-resistant until separation of the anchor means and child-resistant thereafter.
  • the depending skirt of the outer part of the closure is connected to an anchor band by a removable tear band: the anchor band being retained after removal of the tear band as a visual indication that the tear band has been removed.
  • the anchor band itself may be secured to the depending skirt by tearable means in the form of a line of weakening such that the whole anchor band is removed, This may be advantageous where it is desired to reuse the container since no band is left remaining once the container has been opened.
  • a container/ closure assembly comprising a container having a screw neck finish and annular anchor bead, and a closure comprising an inner cap screwed to the container, an outer cap applied over the inner cap and having a depending skirt, an anchor band anchored to the anchor bead on the container, and a removable tear band between the depending skirt and the anchor band, and interengageable drive means on the inner and outer cap prevented from interengagement until the tear band has axial been torn away and then only by relativelmovement between the caps whereby the.closure is tamper-resistant until removal of the tear band and is child-resistant thereafter.
  • the closure 1 comprises an inner cap 2 and an outer cap 3.
  • the inner cap 2 has a top 4 and a depending skirt 5 on the inner surface of which are screw threads 6 for interengagement with screw threads 7 formed on the neck of a container 8.
  • a seal between the inner cap 2 and the container 8 is provided by an annular, resilient projection 9 which, when the inner cap 2 is positioned on the container 8, seals against the rim of the mouth of the container 8 as shown.
  • the outer cap 3 has a top 10 with a depending skirt 11 and an anchor band 12 connected to the depending skirt 11 by means of a removable tear band 13.
  • the tear band 13 has a tab 14, which may be manipulated by a user to effect removal of the tear band 13, and may include tamper-evident bridge members 15 between the respective parts.
  • the anchor band 12 is provided with an internal, annular groove 16 which interengages with an annular bead 17 of wedge-shaped cross-section on the outside of the neck of a specially profiled container.
  • additional tamper evident means may be provided in the form of frangible spaced apart nibs 22 bridging an annular channel 22 separating the central part of the top 10 from the outer part. The act of pushing the outer cap down will break the nibs 22 because an annular bead 24 on the inner cap will stop downward movement of the central part of the top 10.
  • a container and closure assembly according to this invention is now known under our Trade Mark TRACER-LOK.
  • the inner cap 2 and outer cap 3 are interengageable by means of opposed driving dogs 18 and 19 on the top of the cap 2 and underside of the top of the cap 3 respectively. Also shown are cooperating annular beads 20 and 21 on the outside of the depending skirt of the cap 2 and the inside of the depending skirt of the cap 3 respectively which prevent the two caps being separated from one another.
  • the inner and outer caps 2 and 3 are applied to the container 8 separately.
  • the inner cap 2 is screwed on to the bottle like any ordinary screw cap.
  • the outer cap 3 is then applied over the top of the cap 2 and the bottle neck by simple top pressure, effectively creating a tamper-resistant and child-resistant seal.
  • the closure cannot be unscrewed as the skirt formation of the outer caps prevents the unscrewing dogs 18, 19 engaging with each other.
  • the closure cannot be pulled off because of the interengagement of the bead 17 and groove 16 on the tamper-evident anchor band 12.
  • the closure of the present invention may be used to close the mouth of any suitable container to provide tamper and child-resistance.
  • the profile of the outer surface of the skirt of the outer cap 3 may be ridged to facilitate manipulation as shown.
  • a closure having an inner cap for closing the mouth of a container, an outer cap for locking the closure to the container by removable tamper-resistant means, the outer cap being interengageable with the inner cap on removal of the tamper-resistant means and by pressing the outer cap against the then inner cap such that the inner cap may be released from the container by manipulation of the outer cap, the closure being tamper-resistant until removal of the tamper-resistant means and thereafter child-resistant.
