Definitions

  • British Patent No. A1010762 discloses a bottle closure of the screw-type, in which a screw cap or screw stopper is moulded in one piece from a resilient plastic material with a skirt portion adapted to fit over the exterior of the bottle neck when the closure is fitted thereon and provided with an annular step, rib or equivalent projection or projections on the internal surface of the skirt portion at such a position that it engages beneath a ridge or shoulder provided on the exterior of the bottle neck when the closure is fully screwed home, said annular step or the like being urged by the resilience of the skirt to engage beneath the ridge or shoulder on the bottle neck whereby to prevent or resist unscrewing of the closure so long as the skirt remains intact and connected to the screw cap or stopper, and in which the skirt portion is provided with a line or lines of weakening along which the skirt may be torn to allow the closure to be unscrewed and also with a tab portion which is adapted to be gripped and pulled by the fingers to tear
  • a container and closure assembly comprising a closure having a cap part with an internal screw thread, a tear-away tamper evident band connected to the cap part by a first line of weakness, a captive band connected to the tear-away band by a second line of weakness and an annular lower internal bead on the captive band and a container having an external screw thread on the cap part of the closure, an annular lower external bead below which the internal lower bead on the closure engages when in operative position and a ledge below the lower external bead on to which the captive band will adjust itself after the tear-away band has been removed characterised in that the screw threads on the container and on the closure are discontinuous threads and that the closure has an annular upper internal bead on the tear- away band for engagement below an annular upper external bead on the container.
  • closures having only one internal bead to engage with an external bead on the container are not sufficiently tamper-resistant to defeat dexterous and determined people who wish to tamper with the contents of a container.
  • the tear-away band assists the captive band in preventing unauthorised removal of the closure from the container.
  • the discontinuous thread provided on the closure and on the container is similar to that described in our British Patents Nos. 1430302 and 1483404 in which there is described a container and closure assembly in which the closure comprises a retaining band combined with a screw cap characterised by the provision of a discontinuous screw thread on the cap with inclined lower surfaces when viewed in axial section for engagement with a discontinuous screw thread, around the mouth of the container, with inclined upper surfaces when viewed in axial section the contour of the screw-threads being such that if an attempt be made to unscrew the closure without first tearing away the retaining band, the inclined surfaces of the screw threads abut against one another, the resistance of the retaining'band being sufficient to cause the inclined surfaces on the cap to slip off the inclined surfaces on the container so that the closure goes round and round but does not come off the container.
  • a container 1 has a multi-start discontinuous external screw thread indicated generally at 2, a tearaway band-seating 3 and a captive band-seating 4.
  • a closure 5 has an internal multi-start (in this example four start) discontinuous screw thread 6, a tear away band 7 and a captive band 8. Weakened lines 10 and 11 in the skirt 9 of the closure facilitate tearing away of the band 7.
  • the container 1 is shaped to provide an external annular bead 12 that is nose shaped in section with an inclined upper surface 13 and a substantially horizontal lower surface 14.
  • the closure 5 is shaped by the provision of an upper bead 25 on the inside of the band 7 so that it can easily be pushed downwardly over the bead 12 but when in position on the container 1 as shown e.g. in Figure 5, it is almost impossible to remove the closure simply by an upward movement.
  • the downward movement of the closure 5 relatively to the container 1 is preferably effected by pushing straight down into position but alternatively the closure 5 can be applied by a screwing down movement.
  • the line 10 of weakness substantially coincides with the outer end of the bead 12 so that when the band 7 is torn away the top or cap part of the closure can easily be removed by unscrewing a part turn and can be replaced as required.
  • the band 7 sits comfortably on the seating 3 as shown and the container is shaped to provide a lower bead 15 with which the captive band 8 engages.
  • the engagement of the band 8 with the bead 15 provides an extra tamper proof feature because this engagement makes it even more difficult to remove the closure without first tearing away the band 7.
  • the captive band 8 serves no function other than to partially fill the gap between the bead 12 and the ledge 16 in order to improve the aesthetic appearance of the assembly after initial opening.
  • the screw thread illustrated in the drawings is the same as the thread described in our British Patent No. 1430302 and 1483403.
  • the body part of the container may be of any desired and convenient shape and the parts of the assembly are preferably moulded from plastics material.
  • the invention includes the improved closure with a complete circular captive band and also an assembly of the closure and a container.
  • An important feature of the invention is the provision of a suitable sealing means to protect the contents of the container from contamination. Sealing may be effected by engagement of the outer top surface of the container with the inner top surface of the closure.
  • Reference e.g. to Fig. 6 will show that the container 1 may be shaped at 20 to produce a top annular outer portion 21 with a smooth unbroken surface which can be of reduced diameter but the shaping at 20 is purely optional and the portion of reduced diameter need not be provided.
  • the portion 21 engages with an inner annular portion 22 of the closure see e.g. Fig. 5.
  • the top edge of the container may also be arranged to engage with a resilient washer or similar pad disposed within the closure.
  • the screw thread has four starts but it will be understood that a thread having more or less starts may be used depending upon the circumstances.
  • FIG. 7 it will be noted that the multi-start thread 6 in this example has six starts for co-operation with a container (not shown) also having six starts.
  • a container (not shown) also having six starts.
  • annular sealing bead 22 is provided on the underside 23 of the top of the closure 5. This bead 22 is of importance because in operation when the closure 5 is in position on the container 1 the bead 22 forms a plug which enters the mouth or top bore of the container.
  • an annular sealing bead 24 is provided to seal against the outer surface of the container.
