Definitions

  • This invention is concerned with the provision of a child-resistant and tamper-resistant closure for a container.
  • Zeller Patent No. 1529999 have described a very effective child resistant closure which works on a press and turn principle. That closure can be screwed on to the neck of a container to close the mouth but it cannot be unscrewed without at the same time applying top pressure to the closure.
  • the Zeller Plastic closure is now known on the market as a "Turn Lok” closure and this invention incorporates the features of the "Turn Lok” closure as described in Patent No. 1529999 as the child-resistant feature.
  • Patent No. 1529999 provides a child-resistant press and turn or Turn Lok closure for a container having an externally screw-threaded neck, the closure being made from plastics material and comprising a screw cap and overcap being relatively movable both axially and angularly, projections on one of said caps and co-operating projections or recesses on or in the other of said caps, said projections or recesses having first faces on one side thereof which co-operate to transmit rotational movement from the overcap to the screw cap when the overcap is rotated in a direction to screw the closure onto the neck of a said container and second faces on the opposite sides thereof, the second face of each projection or recess of one of said caps being a cam face whereby, in use, the overcap will rotate relative to the screw cap with said projections or recesses of the different caps camming past one another when the overcap is rotated in a direction to unscrew the closure from the neck of a said container unless the overcap is moved axially relative to the screw
  • the Turn-Lok closure is very efficient as a child-resistant closure but it is not tamper-resistant and recent events in USA have shown that it is desirable to sell certain products e.g. food, medicaments, toilet preparations and so on in containers with tamper-resistant closures so that purchasers can see whether the container has been opened. However, once opened legitimately by the purchaser, it is essential with products hazardous to children that the package remains child-resistant. It is therefore an object of the present invention to provide a Turn-Lok closure with a tamper-resistant feature.
  • a Tunr-Lok closure with a child-resitant press and turn feature characterised in that the closure is also provided with tamper-resistant means including a safety band connected to the Turn-Lok part of the closure by frangible means.
  • the safety band when the closure is in position the safety band may be held down by engagement with an annular projection on an associated container so that when the closure is removed the frangible means, which connect the band to the skirt of the screw cap of the Tunr-Lok part of the closure, are broken.
  • the safety band is connected by the frangible means to the skirt of the overcap.
  • the upper edge of the safety band is provided with serrations or fine teeth for co-operation with serrations or fine teeth on the skirt to which the safety band is connected.
  • Each of the two embodiments may be assembled and i applied to the container in one screwing-on operation.
  • the closure may conveniently be divided into two parts, firstly a child-resistant part disposed above the arrow A and secondly a tamper-resistant part disposed below the arrow A.
  • the child-resistant part is a standard Turn-Lok closure as described in UK Patent No. 1529999 and comprises an overcap 1 and a screw cap 2, the screw cap 2 can move axially within the overcap 1 and when once in position on the neck of a container 3 overcap 1 can be turned freely in relation to the screw cap 2 as long as projections on the screw cap and the overcap are not caused to interlock by the application of axial pressure to the overcap.
  • Full details of the construction and operation of the Turn-Lok closure are given in UK Patent No. 1529999 and so further description will not be given here.
  • the screw cap 2 has a tamper-evident band 4 connected to the bottom of the skirt of the screw cap 2 by frangible bridge members 5 disposed in gaps 6 in the band 4.
  • the band 4 also has an internal annular bead 7 to engage below an external annular bead 8 on the neck of the container 3
  • the lower edge of the skirt of the screw cap 2 has serrations or fine teeth 9 to engage with serrations or ' fine teeth 10 on the upper edge of the band 4 when the closure is being screwed onto the container.
  • the closure In operation the closure is applied to the mouth of the container and is screwed on in the usual way.
  • the act of screwing the closure onto the container causes the screw cap 2 to move slightly towards the band 4 due to pressure being applied to the closure and this causes the fine teeth or serrations 9 to engage positively with the fine teeth or serrations 10 on the band 4 so that the band 4 turns with the screw cap 2 and the bridge members 5 flex but do not break.
  • the bead 7 passes over the bead 8 and snaps into position below the bead 8 as shown in Figure 1.
  • the closure When the closure is to be unscrewed axial downward pressure is applied to the closure so that the projections or engaging dogs with matching recesses on the screw cap 2 with the overcap 1 begin to rise.
  • the band 4 resists turning, because the bead 7 has settled firmly below the bead 8.
  • the frangible bridge members 5 therefore break as the closure is being removed.
  • the overcap has an annular projection 11 which, in operative position, is disposed below an annular projection 12 on the screw cap in such a position that the overcap 1 can undergo limited upward and downward movement relatively to the screw cap 2, in the manner described in greater detail in UK Patent No. 1529999.
  • bridge members 5 have a. reduced or weakened portion at their point of connection to the skirt of the screw cap 2.
  • An annular deformable sealing member is arranged for co-operation with the rim around the mouth of the container 3 as shown in the drawing.
  • the second embodiment of the invention differs from the first embodiment in that the tamper-evident band 4 is connected to the overcap 1 instead of to the screw cap 2.
  • the same references are used in Figure 2 as in Figure 1, for the same parts.
  • the screw cap 2 can be first applied and the overcap 1 can be applied by top pressure only as a secondary sealing operation.
  • the closure in both its embodiments is preferably made of a suitable resilient plastics material by a moulding operation and as shown we prefer to provide the overcap with vertical serrations.
  • the container is preferably made of glass with a special neck profile, as shown, for co-operation with the closure, but can, of course, be made from any appropriate alternatives moulded in various plastic materials or fabricated in aluminium or sheet metal.
