  • closure member will be referred to as being fitted to a container which will generally comprise a jar or bottle. It will, however, be understood that the term container is intended to have a much wider application in that the invention is applicable to any removable lid, plate or closure member when fitted to a supporting structure.
  • the invention provides a tarnperproof closure for a container as herein defined, wherein said closure (or container) is formed around its periphery with a plurality of spaced projections or ridges which are of unequal circumferential lengths and spaced apart by unequal circumferential distances, and said container is provided with a locking ring which is rotatable relatively to said closure and is formed around its periphery with a plurality of projections or ridges forming therebetween a plurality of spaced slots, which slots have a circumferential length and are so positioned on said locking ring as to permit the passage therethrough, as said closure is engaged on said container, of said ridges or projections on said closure when said closure cap is located in a predetermined rotational position relative to said locking ring, said closure cap being rotated thereafter from said predetermined position to'prevent ready removal of said closure.
  • the essential feature of the invention is the provision of projections or ridges on the closure (or container) which are of unequal length and which are spaced apart by unequal circumferential distances around the closure. Such as arrangement ensures that the closure can only be removed from the container when the closure is located in only one position in relation to the container thus preventing any ready access or accidental opening of the container.
  • the locking ring is formed as an integral part of the container wall.
  • a second locking ring may be provided rotatable relatively to both the closure and the container, the second locking ring being provided with slots corresponding to those on the container wall.
  • the closure may be provided with a tear-off strip having an annular projection engageable with an annular groove in the wall of the container.
  • the invention is also applicable for use with screwthreaded containers and in one such embodiment the projections or ridges on the closure are located in different planes transverse to the container axis.

  • the outer surface of the skirt portion 11 is formed with ridges or like projections 14.
  • the skirt portion 11 abuts a shoulder 15 formed on the wall 16 of the container 13 when fitted to the container so as to provide a smooth exterior surface.
  • the inner surface 117 of the shirt portion H of the cap 10 is formed with a plurality of circuniferentially extending projections or ridges 18 which are shown more clearly in FIG. l of the drawings by the reference numerals 18a to 18f.
  • the projections Ida to 18f are all of unequal circumferential length and they are spaced apart by distances indicated by the reference numerals 19a to 19f which are also of unequal circumferential length.
  • the outer surface of the wall 1.6 of the container 13 is formed with an annular groove 20.
  • the outer surface of the wall 16 above the annular groove 20 is provided with a plurality of slots 21a to 21f which extend axially from the groove 20 to the mouth of the container.
  • the circumferential length of the slots 21a to 21f corresponds with the circumferential length of the projections 18a to 18f on the cap 10, the slots being angularly positioned and spaced apart by dis tances 22a to 22f which also correspond to the distances 19a to 19f between the projections on the cap 10.
  • the cap 10 in one angular position relative to the container 13 can be axially fitted thereon by the passage of its projections 18 through the corresponding slots 21 on the container.
  • the lower edge of the skirt portion 11 of the cap 10 engages is not in the correct angular position.
  • the upper edge of the projections 18 presents a flat horizontal surface.
  • FIGS. 6 and 7 of the drawings a modification is shown of the embodiment of FIGS. 1 to 5.
  • the wall 16 of the container 13 is formed with a second annular slot 26 which is engaged by an annular projection 27 formed on the inner surface of the lower end of the skirt portion 11 of the cap 10.
  • the lower surface of the projection 17 is inclined so as to allow the push fit engagement of the annular projection 27 in the annular groove 26.
  • the skirt portion 11 of the cap 10 is formed with an annular score or weakening line 28 and the portion of the skirt 11 below the line 28 is provided with a tag 29 to enable this part of the skirt portion to be removed as a tear-off strip or band.
  • the modified embodiment of FIGS. 6 and 7 thereby provides a pilferproof container as the removal of the skirt portion below the line 28 will indicate unauthorised removal of the closure.
  • FIGS. 8 and 9 of the drawings a container and closure cap is shown which provides for greater security to prevent ready access to the container.
  • the cap 30 has a depending skirt portion 31 provided around its inner periphery with a plurality of spaced projections 32, the projections being, as before, of unequal circumferential length and spaced apart by unequal circumferential distances.
  • Corresponding slots 33 are provided on the outer wall 34 of the container 35 by means of a plurality of spaced projections 36 which are formed on and extend outwardly from the wall of the container.
  • the cap 30 is engaged on the container 35 by axial movement so that in the correct angular position the projections 32 engage and pass through the corresponding slots 33 on the wall of the container. Thereafter the cap 30 is rotated to a random position relative to the container.
  • the container is provided with a second locking arrangement in the form of an annular ring 37 mounted on the container 35 for rotation independently thereto about the container axis.
  • the ring 37 may be held against axial movement by a shoulder or ridge 38 on the container and the top edge of the locking ring is formed with circumferential projections 39 which correspond to the projections 36 on the container so as to provide similar spaces or slots 40.
  • the projections 36 and 39 must therefore be in line by correct rotation of the locking ring 37.
  • the cap is rotated to a random position and thereafter the locking ring 37 is also rotated relative to both the cap and the container to a random position which effects greater security.
  • code signs or other indications may be marked on the cap, container and locking ring.
  • FIGS. 10 to 12 of the drawings a simplified embodiment is shown in which both the container and cap can be easily manufactured by moulding techniques.
  • the container 41 has inclined side walls 42 and, as shown more clearly in FIG. 12, the slots 43a to 43f are formed in a flange 44 projecting outwardly from the top edge or mouth of the container so as to receive the corresponding projections 45a to 45f formed along the inner surface of the periphery of the skirt portion 46 of the cap 47.
  • FIGS. 13 to 15 of the drawings illustrates the application of the invention to a screw top container.
  • the container comprises a bottle 50 having a neck 51 provided with the usual screw threads 52.
  • the neck 51 is formed at its top edge with an outwardly projecting flange 53 which is slotted as in the previous embodiment to provide spaces 54.
  • the cap 55 has a skirt portion 56, the inner surface of which is provided with a plurality of spaced inwardly extending projections 57.
  • the projections 57 are spaced around the inner periphery of the skirt portion 56 in a random manner and are of unequal circumferential length.
  • the projections 57 in this embodiment are located in different planes transverse to the axis of the container and in effect provide a broken screw thread on the inner periphery of the cap 55.
