Definitions

  • the ring has weakening points at which it can be broken so that it can be removed from the cap and the cap unscrewed.
  • the ring is located so that its axial movement is limited and it is preferably of a colour different from the cap for distinction purposes.
  • This invention relates to the tamperproof closuring of containers wherein a closure cap is screwed to a corresponding neck or top of a container to effect the closing of the latter.
  • a closure cap is provided with a catch ring which is located under the cap when the latter closes the container.
  • the ring has a plurality of ratchet projections which extend radially inwards of the ring and engage a ring of ratchet teeth on a peripheral region of the container.
  • the catch ring is connected to the cap by means of fracture bridges which fracture when the cap is unscrewed with sufficient effort, the catch ring being prevented from rotating by virtue of ratchet projections engaging said ratchet teeth. The fracturing of the said bridges is a clear indication that the cap has been unscrewed, intentionally or unintentionally.
  • Caps and their catch rings are usually moulded integrally in plastics material in order that the bridges can yield resiliently as the projections ride over the ratchet teeth.
  • Our invention relates to a closuring arrangement having similarities with the known arrangement, but which, at least in its preferred form, does not suffer from the aforesaid drawbacks.
  • a tamperproof closure which comprises a closure cap and a separate catch ring and which is for the tamperproof closuring of a container having a screw threaded region to which the cap may be screwed to close the container and a peripheral region adjacent the screw threaded region which has one or more teeth or recesses, said cap having means defining a support ring over which there is or may be placed the catch ring, and said catch ring having one or more inwardly directed projections which extends or extend through the support ring so as to ride along the peripheral region of the container as the cap is being screwed thereto but to engage said tooth or teeth or recess or recesses of the container when the cap closes same to prevent the cap from being unscrewed, and said catch ring further being adapted to be broken so that it can be removed prior to and enabling the cap to be unscrewed from the container.
  • the presence or absence of the catch ring is used as a means of indicating if the container cap has been removed, although clearly the presence of a broken catch ring on a closed container would also indicate tampering.
  • the catch ring may be adapted to be brokenby being weakened along a line extending from edge to edge of the ring or by being slotted to provide a region of reduced section and a tear tab may be provided as an integral part of the ring adjacent to where it is weakened to facilitate fracture and removal of the catch ring.
  • the cap preferably has an outwardly directed flange ring adjacent the means defining the support ring to prevent the catch ring from being moved axially of the cap and out of engagement with said teeth.
  • the invention in another aspect provides the container having a cylindrical outlet neck which is closed by a tamperproof closure as aforesaid, said outlet having an external threaded portion to which the closure cap is screwed, and an external peripheral region having one or more projections or recesses engaged by the projections of the catch ring, said catch ring being sufficiently restrained from axial movement relative to the cap and outlet so that the only method of removing same from engagement with the teeth is by breaking same.
  • the cap can be used again with another catch ring and the cap and catch ring are quite separate parts capable of manufacture by separate manufacturers.
  • Each part is novel in itself and the invention also provides therefore third and fourth aspects and according to the third aspect there is provided a closure cap for use in the tamperproof closure as aforesaid, said cap comprising a top from which depends a circular sectioned skirt and at the bottom of the skirt there is a means forming an extension of the skirt and defining the support ring and having a circumferential slot or space of the or each inwardly directed proportion of a catch ring so that the catch ring can be slipped over the said means, and the cap further has a surface extending radially outwards of said means against which the catch ring abuts in being slipped over said means.
  • the fourth aspect of the invention provides a one-piece catch ring which has a one or more inwardly directed projections and is adapted to be broken at a particular location and subsequently uncoiled.
  • FIG. 1 is an exploded perspective view showing a container catch ring and closure cap
  • FIG. 2 is a perspective view of the components of FIG. 1 when in assembled condition
  • FIG. 3 is a sectional side view to an enlarged scale showing the container neck when tamperproof closed by the cap and ring of FIG. 1;
  • FIG. 4 is a sectional elevation to an enlarged scale and taken on line III-III of FIG. 3;
  • FIGS. 5 and 6 are respectively a side elevation and a sectional elevation on line VIVI of FIG. 5 of part of the clamping ring.
  • the closure arrangement for the neck 12 of a container 14 comprises basically a closure cap 16 and a catch ring 18.
  • the closure cap 16 is adapted to be screw-threaded to a threaded region 20 for the container neck to close the container.
  • cap 16 interior of cap 16 is provided with corresponding screw threads 16A (FIG. 3) for this purpose.
  • the cap 16 is generally thimble shaped insofar as it has a top 17 and a skirt and at the bottom of the skirt there is a radially outwardly extending flange 22 under which is means defining a support ring for supporting the catch ring 18.
  • Such means on the cap comprises arcuate seat ledges 24 with spaces 26 therebetween.
  • Each ledge 24 has a groove 24A which extends peripherally of the cap.
  • the catch ring 18 is of flexible material and is provided with a plurality of inwardly and obliquely directed projections 28 which correspond in number and position to the spaces 26 in the cap support ring.
  • the catch ring 18 has three weakened regions 30 (see FIG. 5) defined by slots 30A extending into the ring but staggered circumferentially of the ring. Associated with each projection 28 there is a rib 34 which is located to the inside of the ring and extends axially of the ring. Associated with each weakened region 30 is a finger pull tab 36 which is located to the outside of the ring. The inner surface of the ring is provided with a peripheral rib 37 for engaging the grooves 24A on ledges 24 as shown in FIG. 6. The ring is preferably moulded as a one piece unit. Although three weakened regions 30 have been shown, it is to be appreciated that any desired number in any desired distribution may be employed.
  • the ring 18 slips over the support ring 24 as illustrated by arrows 38 in FIG. 1, so that the projections 28 are located in spaces 26 and extend inwardly of the support ring of the cap 16.
  • the meeting edges of ring 18 and the ledges 24 are chamfered (as shown in FIG. 6) or rounded to facilitate slipping of the ring over the ledges.
  • the cap and its associated catch ring 18 can now be screwed onto the threaded portion of the container 12.
  • the container 12 is provided with a plurality of ratchet teeth 21 which are spaced round a peripheral region located under threaded portion 20. It is to be noted that some 21A (FIG. 4) of the teeth are only partially formed or stunted. This is because the container is moulded in a split mould and if the teeth were all fully formed, difficulty could be experienced in opening the mould.
  • the region of ratchet teeth is bounded at the opposite side from threaded portion 20 by the shoulder of the container 14.
  • the projections 28 are in axial overlap with the teeth 21.
  • the cap 16 is adapted to be screwed onto container 12 by turning same in the direction indicated by arrow 42 in FIG. 1 and it will be noticed that the inclined faces of the ratchet teeth 21 are presented to the projections 28 so that when the cap is being screwed on in the direction of arrow 42 the projections 28 ride over the teeth and do not impede the screwing on the cap. If an attempt is made to unscrew the cap after the projections have started to ride over teeth 21, then the projections 28 engage behind the ratchet teeth 21 and prevent unscrewing movement.
  • FIGS. 2, 3 and 4 show the cap 16 screwed fully home on the container 12 with the catch ring 18 trapped between flange 22 and the container shoulder so that it cannot be moved axially relative to the ratchet teeth 21 in either direction.
  • This is a substantial advantage of the embodiment of the invention because it makes tampering without breaking the catch ring effectively impossible.
  • the container shoulder instead of using the container shoulder as an abutment to the ring 18, or where the container has no shoulder, e. g. in a conical container, the container neck would be provided with an abutment flange.
  • a sealing gasket 44 inside and carried by cap 16 seals against the top of neck 20.
  • the gasket may be for example of rubber or similar material.
  • the ribs 34 serve the function of accurately locating the ring 18 relative to the ledges 24 as shown clearly in FIG. 4.
  • the forces resisting unscrewing are forces set up by compression of projections 28 and not by tension on the weak regions 30.
  • the cap can be made to burst before the ring 16 yeilds.
  • ring 18 can be of a different colour from cap 16 making the arrangement more readily obvious that ring 18 is a tamperproof device. Secondly, because in normal use there is no rupturing in any way whatsoever of the cap 16, it can be used again with an unbroken catch ring 18.
  • the cap 16 is positively locked from being unscrewed from the container by the projections 28 engaging the teeth 21.
  • This overcomes the risk of the seal being broken accidentally, for example, by someone trying to unscrew the cap before they appreciate that the arrangement is intended to be tamperproof.
  • the positive engagement further helps in preventing the cap from unscrewing due to vibration such as may be met when the container is being transported. This advantage is considered to be of considerable importance because many troubles arise because plastic caps work loose in transportation particularly when they are screwed to plastics containers because of the low coefficient of friction between plastics material and plastics material.
  • the cap ring and container be constructed in plastics material although this is not absolutely essential.
  • the component parts could, for example, be constructed from metal such as tin plate, but in a preferred case, the cap is of high density polythene and the ring is of low density polythene.
  • the catch ring could have a single projection and the peripheral region could have a single tooth engageable with such projection to lock the cap in position.
  • the one or more teeth on the peripheral region of the container it may have one or more recesses into which the one or more projections can engage to lock the cap in position casing the container.
  • Tamperproof closures of the type to which the invention relates are used in many industries.
  • the main field of application can be summarized as the transportation of valuable, corrosive and expensive liquid materials in containers.
  • a tamperproof closure which comprises a closure cap and a separate catch ring and which is for the tamperproof closuring of a container having a screw threaded region to which'the cap may be screwed to close the container and a peripheral region adjacent the screw threaded region which has at least one abutment, said cap having means defining a support ring over which the catch ring is adapted to be placed and said catch ring having at least one inwardly directed projection which extends through the support ring so as to ride along the peripheral region of the container as the cap is being screwed thereto but to engage said abutment of the container when the cap closes same to prevent the cap from being unscrewed, and said catch ring further being adapted to be broken so that it can be removed prior .to and enabling the cap to be unscrewed from the container.
  • a container having a cylindrical outlet neck which is closed by a tamperproof closure which comprises a screw closure cap and a separate catch ring
  • said cap having means defining a support ring over which the catch ring is placed, and said catch ring having at least one inwardly directed projection which extends through the support ring
  • the outlet neck of the container having an external threaded portion to which the closure cap is screwed, and an external peripheral region having at least one abutment which is engaged by a projection of the catch ring, preventing unscrewing of the cap, said catch ring being adapted to be broken so that it can be removed prior to and enabling the cap to be unscrewed from the container, and further being sufficiently restrained from axial movement relative to the cap and outlet that the only method of removing the ring from engagement with the abutment is by breaking the ring.
  • a one-piece catch ring for a tamperproof closure which has a plurality of inwardly directed projections and which is adapted to be broken at a particular location and wherein a weakening of the ring at said location is created by two axial slots extending partially across the width of the ring, said slots being circumferentially staggered.
