Definitions

  • This invention relates to closures for containers which are not only child-resistant but also tamper-evident.
  • One of the most successful in the snap-on field has been one in which the cap has to be rotated to a predetermined orientation (indicated by arrows or other indicia on the cap and on the neck of the container) to align a lug on the inside of the cap with a gap in an annular bead around the neck of the container before the cap can be pushed off. This is the subject of British Patent Specification No.
  • each of these the strip is of the straightforward tear-off kind, although in Figures 7 and 8 of British 1 520 808 there is shown a version in which, as in some of the known tamper-evident caps mentioned above, the cap is joined by a tear-off intermediate band to a captive band which remains on the neck of the container and forms an anchorage for hinge by which the closure is retained on the container.
  • a drawback of this arrangement is that after removal of the tear-off band and when the closure is thereafter being used in its normal child-resistant mode, it is necessary to turn the interconnected closure and captive band to a child-resistant position after opening.
  • the present invention is concerned with a further development in child-resistant tamper-evident closures of the general kind described above, ensuring even more effectively than the known ones that the closure cannot be levered off by unauthorised persons without breaking the band and furthermore avoiding the known problems of unwanted breakage during 'capping', that is to say, as the closure is fitted to the container.
  • a further aim is to make tampering more obvious than in some of the known closures.
  • a child-resistant and tamper-evident snap-on closure assembly comprising a closure having a top wall and a skirt and there being co-operating circumferential beads and lugs on the inside of the skirt of the cap and on the neck of the container making it necessary to turn the closure to a certain angular position in relation to the neck to bring a lug on the skirt or neck into alignment with a gap in the bead on the neck or skirt (for example as disclosed in the above-mentioned British Patent Specification No.
  • the skirt of the cap being joined by a breakable web or webs to a circumferentially extending tear-off band which in its turn is joined by a breakable web or webs to a continuous circumferentially extending captive band on the neck of the container, and that captive band has at least one lug co-operating with a lug or lugs on the neck of the container to prevent rotation of the cap to the said certain angular position until the tear-off band has been removed to disconnect the cap from the captive band.
  • the closure illustrated is moulded from a suitable plastics material and comprises a cap with a top wall 1 and skirt 2, the lower edge of the skirt being joined by a thin breakable web 3 to the upper edge of a tear-off band 4, and the lower edge of the band being joined by a similar thin breakable web 5 to a further band 6.
  • the cap is of a child-resistant construction similar or identical to that described in British Patent Specification No. 1 295 207 or U.S. 3 627 160, with an interrupted bead defined by two internal circumferentially spaced shoulders 7 with a gap 8 between them, a vestigial bead 9 and a substantial inwardly projecting lug 10.
  • a finger tab 11 On the outside of the cap in alignment with the lug is a finger tab 11 to facilitate removal of the cap when it has first been turned to the right angular position on the neck of the associated container, with the lug 10 in a gap 12 in the bead 13 (Figs 7 and 8) on the neck of the container.
  • the tear-off band 4 has a finger tab 14 to grasp for tearing it off and the webs 3 and 5 are omitted in this region to make the initial movement easy.
  • the webs are otherwise continuous, although instead of such continuous webs one could use individual circumferentially spaced webs.
  • the inside of the tear-off, band 4 is smooth and cylindrical, with nothing engaging the neck of the container.
  • the lower band 6, however, has a ring of Vee- section vertical ribs or lugs 15 (sixteen of them in the example shown) on its inside face, co-operating with ribs 16 on the neck of the container. These have the effect of preventing rotation of the band 6, and hence of the cap, until the band 4 has been removed.
  • Theribs 15 on the neck have pointed upper ends to ensure that there are no problems on capping.
  • the circumferential positions of the ribs are chosen so that the closure cannot be put in place in the 'aligned' position, i.e. with the lug 10 aligned with the gap 12.
  • the closure according to the invention is easy to apply to the container (the so-called 'capping' step) because unlike the known closures having a band that resists upward movement, there is no circumferential internal bead on either of the bands that needs to be forced over a circumferential bead on the neck of the container.
  • ribs 15 and 16 are shown (sixteen on the band 6 and eight on the neck), it would in theory be possible to have only a single rib on either the band or the neck provided there are sufficient on the other to prevent turning to the 'aligned' position. However we prefer the number shown.
