Definitions

  • This invention relates to a container having a closure member which has tamper indicating means such that it is visibly apparent when the container has been tampered with.
  • the closure may be able to be removed from the container without severing the band portion if the diameter of the container neck is too small.
  • this difficulty due to variation within normal tolerances has necessitated the utilization of expensive manufacturing methods for containers to be used with such closure members.
  • EPA 0117 104 A3 discloses in Figure 5 a container and a closure member therefor, the container having a neck portion defining an opening over which the closure is receivable, the neck portion having a neck finish around which a peripheral face is defined by a circumferential bead of the neck portion and having a circumferential, radially extending shoulder below said peripheral face.
  • the closure member has a cap member defining a top wall and a depending peripheral skirt integral with the top wall; an axially spaced, separable band portion interconnected by several frangible bridge elements to an edge of the skirt remote from the top wall; and locating members which are formed integrally on said band portion, said locating member being at a location spaced from the top wall and being radially dimensioned such that they are receivable below, and in opposed relation to, said shoulder of the neck portion on application of the closure member to the container; the band portion having circumferentially therearound at least one region at which its inner surface is provided with radially inwardly extending formations. In EPA 0117 104A3 these formations form an extension of each bridge element.
  • Each said radially inwardly extending formation is spaced from said top wall and is dimensioned radially from said inner surface of said band portion such that, on application of the closure member to the container, each said formation possibly defines centralizing means located around said peripheral face of the container neck portion, with the centralizing means so closely adjacent to said peripheral face that, notwithstanding variations in the diameter of the container neck portion within normal tolerances, the closure member may be centrally located on the container neck portion and transverse movement of the closure band portion relative to the neck portion may be inhibited.
  • said locating member comprises an annular flap (34, 134, 234) hingedly connected to the inner surface of the band portion (14, 114, 214) for movement between an inoperative orientation and an operative orientation, such that in the inoperative orientation the flap extends away from the top wall and in the operative orientation the flap extends radially inwardly and axially toward said top wall (16, 116, 216); said annular flap (34, 134, 234) being connected to said inner surface around a hinge line (35, 135, 235).
  • This invention enables the locating member to be formed in a single operation which is the molding process and the locating member is such that, upon initial tightening the closure member onto the container, an edge of the annular flap remote from the cap member abuts onto the ramp portion of the container neck and upon further tightening the annular flap is caused to "flip" over to an operating orientation such that the flap moves about its hinge and then projects radially inwardly but axially towards the cap member. Upon still further tightening of the closure member the annular flap is moved so as to be received behind the shoulder on the neck of the container. In a preferred, alternative arrangement, the annular flap may be flipped over to such orientation before application of the closure to a container.
  • the skirt wall is preferably provided on an inner surface thereof with a screw thread for threaded co-operation with the neck of a container.
  • the cap member may be provided with any other retention means as are known in the art for securing the cap member onto the top of the container.
  • the under surface of the top wall of the cap member has an annular sealing fin and an annular abutment.
  • the fin and abutment preferably are substantially concentric with the abutment radially spaced from said sealing fin such as radially outwardly of the latter.
  • the abutment and sealing fin are arranged so that application of the closure member onto a container causes the sealing fin to be deflected or deformed by engaging the end rim of the container, thereby pushing the sealing fin up against the abutment to form a seal both with the abutment and the container rim.
  • the inner surface of the top wall of the closure is simply provided with an annular sealing fin.
  • the sealing fin has an external diameter related to the diameter of the inner circumferential surface of the neck of a container with which the closure is to be used such that, on application of the closure to the container, the sealing fin is received into the neck of the container and provides a fluid tight seal around that inner surface.
  • the external surface of the sealing fin is of frusto conical form and increases in diameter toward the top wall, so that the tightness of the seal achieved between the fin and the inner surface of the neck of the container increases as the closure is applied to the container.
  • the band portion is of an annular configuration and is adapted to be received around the neck of a container.
  • the band portion is of greater internal diameter than the cap member such that, upon fitting the closure member onto a container, the band portion can quite easily pass over the thread or other means provided on the container for engaging the cap member.
  • the locating member can be a portion of reduced diameter defining an annular shoulder or may be comprised of resilient finger-like protrusions circumferentially spaced around the inner face of the band portion so that the end of said fingers similarly abut behind the shoulder on the container neck.
  • centralizing means Located on the inside face of the band portion there is provided centralizing means.
  • the centralizing means is adapted to coact upon the neck of the container in order to ensure a neat fit of the band portion around the neck of the container and to prevent slippage of the locating means from behind the container neck shoulder by lateral displacement of the band portion.
  • the centralizing means is provided by a number of lugs which are uniformly circumferentially spaced around the inner surface of the band portion. These lugs are preferably located towards the top of the band portion, commencing substantially adjacent to the link means and extending away from the cap member, but preferably not continuing so far as to reach the hinge of the locating member.
  • the closure of the invention preferably has a locating member of the above described form of an annular flap or of circumferentially spaced protrusions.
  • the centralizing means most preferably terminate short of the lower edge of the band portion such that the centralizing means does not prevent the locating member, when in its operating orientation and with the closure applied to a container, from being able to contact the inner surface of the band portion.
  • the internal diameter of the locating member when in its operating orientation in the case of an annular flap or when similarly oriented in the case of circumferentially spaced protrusions, preferably is greater than the diameter of the thread finish of the closure. Also, in each case, it is more preferable that the overall axial relationship of the closure and its band portion are such that two conditions are achieved. The first of these conditions is that, on application of the closure to a container, the thread of the closure is able to commence its threaded engagement with the thread of the container neck before the locating member first engages the ramp portion of the container neck with which the centralizing means substantially prevents lateral movement of the closure.
  • the ramp portion most preferably is defined by a bead which also defines the shoulder behind which the locating member is received.
  • the second condition is that the locating member, again on application of the closure, locates behind that shoulder after the container neck engages the sealing fin to achieve a seal.
  • the locating member is to engage behind the shoulder after the sealing fin has been pushed to seal against the abutment.
  • the locating member is to engage behind the shoulder after such seal is achieved.
  • the at least one bridge element which interconnects the skirt of the cap member and the band portion may be of a variety of types.
  • the at least one element comprises a frangible, circumferentially extending zone of reduced thickness joining the cap member to the band portion.
  • the closure preferably includes abutment means for protecting the elements against breaking both during application of the closure to a container and during ejection of a formed closure from its moulding die.
  • the abutment means may comprise a plurality of axially extending protrusions spaced around the edge of the skirt to which the band portion is connected.
  • the protrusions are of lesser axial extent than the bridge elements.
  • the protrusions engage the opposed edge of the band portion and thereby limit the extent of such drawing and, hence, of the force exerted on the bridge elements.
  • the protrusions may be provided around the opposed edge of the band portion, so as to similarly engage the edge of the skirt.
  • the locating member When a closure member of the type described is fitted to a container neck, the locating member is received behind the shoulder defined on the neck of the container. Upon tightening of the cap member onto the container to achieve this locating the centralizing means engages the ramp portion and, upon further tightening, draws the cap member centrally around the container neck.
  • unscrewing the closure for the first opening of the container is resisted by the locating member and is possible only be severing the bridge elements between the cap member and the band portion.
  • the arrangement most preferably is such that, upon returning the closure to the container, the severing is visibly apparent, thereby indicating a previous opening of the container.
  • the band portion is able to fall away from the closure to make that severing visible even when the cap member is returned.
  • the closure member of this invnetion is most conveniently formed of a suitable synthetic plastics material, such as by injection moulding.
  • the closure member 10 has a cap member 12 and a band portion 14.
  • the cap member 12 has a top wall 16 with a depending peripheral skirt wall 18.
  • the skirt wall 18 is provided with a thread portion 20 on its inner face for tightening engagement with the neck 22 of a container 24 (shown in Figure 2).
  • An annular sealing fin 26 is located on the under side of top wall 16 of the cap member and is concentric with an annular abutment 28 which is radially outwardly disposed from sealing fin 26. As can be seen in Figure 2, abutment 28 and sealing fin 26 are arranged in such that application of closure member 10 onto container 24 forces sealing fin 26 against the open ended rim 30 of container 24, thereby both with abutment 28 and container rim 30.
  • Band portion 14 is interconnected with cap member 12 by frangible link means or bridge elements 32.
  • Band portion 14 has an annular flap 34 hingedly connected at hinge lines 35 adjacent its edge remote from cap member 12; flap 34 as formed being directed radially inwardly, and axially away from cap member 12, as can be seen in Figure 1.
  • annular flap 34 Upon closure member 10 being received onto neck 22 of container 24, annular flap 34, if still in that orientation, engages on a ramp portion 36 of container neck 22 defined by peripheral bead 38.
  • annular flap 34 Upon tightening of the closure member 10, annular flap 34 is received behind shoulder 40 located on neck 22 of container 24 and also defined by bead 38.
  • flap 34 preferably is caused to flip over to its in use orientation before application of member 10 to container 24, by application of a suitable tool.
  • Bead 41 is of lesser diameter than bead 38, and limits the extent to which flap 34 is able to move radially inwardly on passing over bead 38. The edge of flap 38 remote from its hinge line 35 thus is held in position for engaging shoulder 40, between band portion 14 and bead 41.
  • Band portion 14 has a number of lugs 42 which are uniformly spaced around its inner surface. These lugs are located towards the top edge of band portion 14 commencing substantially adjacent to link means 34. Lugs 42 extend axially on the inner surface of band portion 14, but are of lesser axial extent than that surface and do not extend as far as the hinge of annular flap 34. As can be seen in Figure 2, once closure 10 has been fitted onto neck 22 of container 24 and fully tightened, lugs 42 contact or are spaced slightly from the peripheral face 44 of the bead 38, intermediate ramp 36 and shoulder 40, and thus prevent closure member 10 from being removed from the container neck 22 without severing link means 32.
  • closure member 10 once closure member 10 has been fitted to neck 22 of container 24, unscrewing closure member 10 for the first time will be resisted by the annular flap 34 as it abuts onto shoulder 40. Furthermore closure member 10 cannot be removed, without severing link means 32 due to the uniform abutment of lugs 42 onto the face 44 of bead 38 as transverse movement of band portion 14 relative to container neck 22 is substantially prevented.
  • the arrangement preferably is such that, upon cap member 12 being returned to container neck, the severing of the link means 32 is clearly visible.
  • top wall 116 has only an annular sealing fin 126. Also, the latter is positioned and of a diameter such that its frusto conical external surface engages around the inner surface of container neck 122. As closure member 110 is fully applied to neck 122, a fluid tight seal is achieved between fin 126 and that surface of neck 122.
  • Band portion 114 has a plurality of circum­ferentially spaced lugs 142, similar to lugs 42 of Figures 1 and 2.
  • lugs 42 are of a length such that, with flap 34 in its operating orientation as shown in Figure 2, a partial overlap occurs. With variation in neck finish tolerances, this overlap can make it difficult to draw flap 34 past bead 38 to locate below shoulder 40 unless there is sufficient resilience in the material comprising band 14, its lugs 42 and flap 34.
  • closure members 10,110 is shown in relation to a glass container, although closures according to the invention also can be suitable for plastics containers. Indeed, member 110 is a variant of a form of closure shown in Figure 4 and primarily intended for use with a plastics container.
  • Closure 210 differs from closure 110 of Figure 3 in that it does not include a further bead similar to bead 141. Rather, below shoulder 240 of bead 238, the outer surface of container neck 222 tapers downwardly and radially inwardly, as shown at 246. With a glass container as shown in Figures 2 and 3, it is found that band portion 14, 114 readily falls away after from beads 41,141 on severing of link means 32, 132 so that a positive tamper indication is provided. With a plastics container 224, a bead similar to beads 41,141 would be likely to be frictionally engaged by band portion 214 after severing of link means 232 so that such positive indication is not provided. However, a tapered neck finish as at 246 is found to ensure that band portion 214 does fall away as required, to provide a positive tamper indication.
  • band portion 14 is provided with a respective one of about four protrusions 48.
  • Corresponding protrusions are similarly provided in closures 110 and 210. While, in each case, the protrusions preferably are provided at the edge of the band portion nearest skirt wall 18, 118, 218, they alternatively may be provided on the adjacent edge of that wall and extend toward the band portion.
  • protrusions 48 of closure 10 extend axially over part of the spacing between band portion 14 and skirt wall 18. That is, they are of lesser axial extent than the link means 32.
  • link means 32 During application of closure 10 to a container, the axial and rotational force applied to closure 10 causes link means 32 to flex or deflect so as to reduce the spacing between portion 14 and wall 18. If not limited, such flexing is likely to rupture link means 32, preventing portion 14 from serving its intended purpose. Limitation of such flexing is provided by protrusions 48, the latter being caused to engage the adjacent edge of skirt wall 18 and thereby prevent further transference of forces to link means 42. Protrusions 48 also serve a similar function during ejection of closures 10,110,210 from forming dies.
  • flap 34 when in its operating orientation shown in Figure 2 preferably has an inner diameter which is larger than that of thread finish of the closure, i.e. larger than the diameter of thread 20 (120).
  • the overall arrangement in each embodiment is such that, on application of the closure to container neck 22 (122, 222), thread 20 (120, 220) commences its threaded engagement with the thread of neck 22 (122, 222) before flap 34 (134, 234) hits ramp portion 36 (136, 236) of bead 38 (138, 238).
  • the overall arrangement of Figures 1 and 2 preferably is such that fin 26 is deformed to provide a seal against abutment 28 before flap 34 passes below shoulder 40 of bead 38; while in each of Figures 3 and 4, the overall arrangement preferably is such that fins 126, 226 also provide a seal in neck 122, 222 before flap 134, 234 passes below shoulder 140, 240.
  • the arrangement of lugs 42 shown in Figure 1 is similar to that of Figures 3 and 4. There may be from about six to fourteen of the lugs, such as about 12, at substantially uniformly spaced circumferential locations.
  • the lugs are relatively slight in circumferential and radial dimension; being of the order of 1 to 2 mm circumferentially and 0.2 to 1.0 mm radially.
  • the lugs thus are readily able to be compressed as their band portion passes across ramp portion 36 (136, 236) to locate the lugs 42 (142, 242) in contact with or closely adjacent face 44 (144, 244) of the bead 38 (138, 238). On assuming such position, resilient recovery of the material of which the closure members are made enhances the centering action provided by the lugs.
  • the Figures also illustrate improved neck finishes for containers which exhibit features which are complementary to and co-operate with the closures of the invention.
  • the similar neck finishes of Figures 2 and 3 are suitable for glass containers, while that of Figure 4 is suitable for a plastics container.
  • the glass finish of Figure 3 has closure engaging means, here shown as comprising thread 150.
  • thread 150 there is bead 138 as described above.
  • bead 138 Immediately below bead 138, the above-­mentioned bead 141 is provided; the latter having an outerface which is substantially co-axial with neck 122 and of lesser diameter than bead 138.
  • beads 138,141 are spaced by a narrow groove 152.
  • flange 134 abuts against shoulder 140 of bead 138 to resist removal of the closure unless the applied force is sufficient to rupture bridge elements 132.
  • flange 134 is closely constrained radially between band 114 and bead 141, but substantially co-axially with respect to neck 122 due to the centering action of lugs 142.
  • Flange 134 can flare inwardly by resilient deformation to an extent permitted by groove 152, further facilitating its retention below shoulder 140.
  • band portion 114 then is free to drop away from bead 138 onto the narrower portion of neck 122 below bead 141 to provide a clear visual indication that the container has been opened.
  • Tapered surface 246 enables band portion 214 to freely fall away on rupturing of bridge elements 232.
  • the wider diameter upper portion of surface 246 provides a similar action to that of bead 141 in Figure 2. That is, the upper portion of surface 246 acts, prior to such rupturing, to ensure proper functioning of flange 234; surface 246 co-operating with band portion 214 and lugs 242 in this regard.
