Definitions

  • This invention relates to closures for containers which are not only child-resistant but also tamper-­evident.
  • One of the most successful in that 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.
  • U.S. Patent Specification No 3, 393 816 Another U.S. Patent Specification No 1 342 058 discloses a third version, and also the logical inverse in which an outwardly projecting lug on the neck of the container has to be aligned with a gap in a bead inside the skirt of the cap.
  • the aim of the present invention is to provide a neater and simpler way of adding tamper-evidence to a snap-on child-resistant cap of the general kind described above.
  • a combined child-resistant and tamper-evident closure assembly of the kind comprising a snap-on cap of a circular cross-section which has to be turned to a predetermined orientation in relation to a co-operating neck formation before it can be removed (thereby providing the child resistance) and which furthermore has a tear-off strip which is joined to the remainder of the cap by a line of weakness and interengages with a portion of the neck formation and has to be at least partially removed from the cap before the cap can be removed (thereby providing the tamper indication), there are co-operating tooth or abutment surfaces on the tear-off strip and the neck formation which prevent rotation of the cap to the said predetermined orientation until the strip is detached.
  • the strip prevents removal of the cap without relying on the strip itself having to engage under any bead, and so the bead on the neck usually associated with the tamper-­evident strip can be omitted. This simplifies moulding. However the omission of this bead is not an essential feature of the invention and it could be retained for added security.
  • the strip need not extend all the way round the skirt of the cap. Moreover, it is not essential for the strip to prevent rotation altogether, as long as it prevents rotation to that orientation in which the cap can be removed.
  • the strip has a continuous ring of internal teeth and there is a continuous ring of teeth around the neck of the container so that when the cap is first applied to the container its orientation does not matter.
  • it could, if thought to be simpler, be sufficient to have only a single tooth on either the cap or the container and it would still prevent rotation and still allow initial assembly in any orientation. Indeed , in theory a single tooth on one, fitting between a single pair of teeth on the other could be sufficient but then the cap would have to be assembled onto the container in the correct orientation, which could cause problems.
  • the child-resistant arrangements can be substantially the same as those disclosed in British Patent Specification 1 295 207 and marketed under the trade mark 'Snap-safe'; a cap 1 has an internal bead 2 (Fig. 6) and a lug (not shown) of a circumferential extent allowing it to pass upwards through a gap 3 (Fig. 1) in a bead 4 on the neck of the container provided the cap has first been turned to the correct orientation, as indicated by lining up arrows 5 and 6 (Fig. 1) on the cap and the neck.
  • tear-off band 8 Moulded integrally with the cap 1, and joined to it by a thin breakable web 7, is tear-off band 8 of L-­shaped cross-section (Fig. 6), of which the inner face has a ring of teeth 9. There is a tab 10 for grasping. The teeth 9 engage a matching ring of teeth 11 moulded on the neck of the container below the bead 4.
  • the cap can be fitted onto the container initially in any orientation.
  • the band 8 must be removed before the cap can be turned to a position in which it can be opened and even after the ring has been discarded the closure retains all the advantages of the existing child-resistant caps.
  • child-resistant arrangements could be of a different kind, provided they involve orientation; for example there could be an outwardly projecting bead on the neck that has to be aligned with a gap in an internal bead in the skirt of the cap.
