Definitions

  • the present invention relates generally to tamper-indicating or tamper evident packaging arrangements, and more particularly to a tamper-­indicating plastic closure for a container which functions to provide two modes of interference with the container for enhanced tamper resistance.
  • closures of this nature include an upper cap portion, and a depending pilfer band arranged to interact and cooperate with the container to which the closure is applied.
  • the pilfer band is typically configured so as to fracture and/or separate from the closure cap attendant to closure removal, thereby providing clearly discernable evidence that the container has been partially or completely opened.
  • a tamper-indicating closure it is desirable for a tamper-indicating closure to be as resistant as possible to tampering or the like without visibly discernable evidence thereof.
  • the present plastic closure has been particularly configured for economical and efficient manufacture for use on existing containers, with the closure being highly resistant to tampering, consistent and reliable in performance, and highly versatile for use with a wide variety of different containers.
  • the present invention relates to a tamper-­indicating plastic closure for a container having a typical annular locking ring positioned adjacent to and beneath the threads on the neck portion of the container.
  • the closure includes a pilfer band having a plurality of inwardly extending flexible tabs, with the pilfer band further including a coacting interference bead positioned beneath the flexible tabs.
  • the pilfer band functions to provide dual modes of interfering interaction with the container locking ring for tamper-indication.
  • the present plastic closure includes a plastic cap having a circular top wall portion, and an annular depending cylindrical skirt portion.
  • the skirt portion includes an internal thread formation adapted for coaction with a mating thread formation on the neck portion of the associated container for retaining the closure thereon after application to the container.
  • the present closure further includes an annular, integrally formed pilfer band depending from the skirt portion of the closure cap.
  • the pilfer band is at least partially detachably connected to the skirt portion of the cap by a plurality of circumferentially spaced frangible ribs.
  • the frangible ribs extend between inside surfaces of the skirt portion and pilfer band, with the skirt portion and pilfer band otherwise being distinguished and separated from each other by a circumferential score line which extends partially into the frangible ribs.
  • the pilfer band includes an annular band portion, and a plurality of circumferentially spaced, inwardly extending flexible tabs which extend inwardly of the annular band portion.
  • the pilfer band further includes an annular interference bead extending generally inwardly of the annular band portion, with the interference bead positioned beneath the inwardly extending flexible tabs.
  • the flexible tabs In this disposition of the flexible tabs, they are positioned for interfering engagement with the generally downwardly facing surface of the container locking ring, whereby in this first mode of interference, the free end portions of the flexible tabs engage the locking ring for fracturing the frangible ribs which at least partially detachably connect the pilfer band to the skirt portion of the closure cap. Clearly visible evidence of opening is thus provided.
  • the flexible tabs cooperate and coact with the interference bead of the pilfer band to again interferingly engage and coact with the container locking ring.
  • the flexible tabs are engageable with the container locking ring in the event that the flexible tabs assume an angularly downwardly and inwardly extending disposition relative to the annular band portion of the pilfer band.
  • the flexible tabs are engageable with the container locking ring by disposition between the locking ring and the annular interference bead.
  • the flexible tabs and interference bead are dimensioned relative to the container locking ring so as to resist opening movement of the closure, thereby fracturing the frangible ribs joining the pilfer band to the skirt portion. Again, clear visual evidence of opening is achieved.
  • a scoring bead can be provided which extends circumferentially on the inside surface of the closure, and which desirably acts to support the interior of the closure during formation of the circumferential score which distinguishes the pilfer band from the skirt portion of the closure.
  • at least some of the frangible ribs of the construction can be configured to extend on the inside surface of the pilfer band between adjacent ones of the flexible tabs. Such ribs desirably function to center the pilfer band on the associated container with respect to the locking ring thereof, thus further enhancing tamper resistance.
  • a plurality of circumferentially spaced prestressing projections can be provided on the inside of the pilfer band, with these projections being engageable with the container locking ring for prestressing the frangible ribs joining the pilfer band to the closure skirt portion.
  • This prestressing arrangement can desirably promote failure of the frangible ribs in the intended manner.
  • Closure 10 can be made by various injection-molding or compression-molding techniques, and it can be formed in accordance with the compression-molding techniques taught in U.S. Patent No. 4,497,765, which is incorporated herein by reference.
  • closure 10 includes an upper generally cup-shaped closure cap 12 including a circular top wall portion 14, and a depending, annular cylindrical skirt portion 16.
  • Skirt portion 16 preferably includes an internal thread formation 18 configured for threading engagement in cooperation with the threads T of an associated container C to which the closure is fitted.
  • the plastic closure can be provided with an associated sealing liner, such as illustrated in the above-referenced patent.
  • the present closure further includes an annular pilfer band 20 depending from and at least partially detachably connected to skirt portion 16 of the closure cap.
  • Pilfer band 20 preferably comprises a continuous annular band portion 22 arranged in substantial vertical alignment with skirt portion 16.
  • the pilfer band is at least partially detachably connected to the skirt portion by a plurality of circumferentially spaced frangible ribs 24 which extend between the inside surfaces of the skirt portion 16 and the band portion 22 of the pilfer band.
  • the pilfer band 20 is otherwise distinguished and separated from the skirt portion 16 by a circumferentially extending score line 26.
  • score line 26 and frangible rib 24 together cooperate to provide the desired frangible connection between the pilfer band 20 and the closure cap 12.
  • the closure cap 12 and the pilfer band 20 are formed integrally with each other during molding, with the ribs 24 molded on the inside surfaces of the skirt portion and pilfer band.
  • score line 26 is formed, preferably by use of a scoring cutting blade, thereby distinguishing and separating the pilfer band 20 from the skirt portion 16, with the score line 26 extending partially into the ribs 24.
  • the unscored, "residual" portions of the frangible ribs 24 collectively provide the desired frangible connection between the pilfer band and the skirt portion.
  • an integral connector portion can be provided between the pilfer band and the skirt portion (such as by leaving a portion of the closure uncut by score line 26) whereby the pilfer band remains connected to the skirt portion 16 after fracture of the ribs.
  • one or more fracturable areas can be provided in the pilfer band itself, whereby the pilfer band splits and fractures during closure removal from the associated container.
  • the pilfer band includes a plurality of circumferentially spaced, inwardly extending flexible tabs 28 which extend inwardly from the annular band portion 22 of the pilfer band.
  • twelve evenly spaced tabs 28 are provided about the circumference of the pilfer band, with each tab having a width of about 6.1 mm (about 0.240 inches), and a thickness of between about 0.3 mm (about 0.012 inches) and 0.5 mm (0.020 inches).
  • the free end portions of adjacent ones of the tabs 28 are closely spaced (about 0.5 mm (0.020 inch) spacing) when the tabs extend horizontally inwardly.
  • This horizontally inwardly extending orientation of the tabs is indicated in phantom line, and represents the orientation in which the flexible tabs 28 are preferably molded.
  • the flexible tabs 28 cooperate with an annular locking ring portion L of container C for effecting fracture of frangible ribs 24, thereby providing the desired tamper-indication.
  • the free end portions of the flexible tabs are engageable with the locking ring L.
  • the flexible tabs are configured to cooperate with an annular interference bead 30 provided generally at the lower edge of annular band portion 22 of the pilfer band 20.
  • the interference bead 30 is positioned beneath the flexible tabs 28, with the upper, inward edge portion of the interference bead positioned relative to the flexible tabs so that this edge portion is engaged by the tabs in the second failure mode.
  • the inside diameter of the interference bead is about equal to or slightly less than an inside diameter collectively defined by the inside surfaces of the circumferentially spaced frangible ribs 24.
  • the flexible tabs 28 engage the container C and are moved upwardly generally to an upwardly extending, out-of-the-­way disposition as the pilfer band moves downwardly relative to the container threads T and the container locking ring L.
  • the flexible tabs 28 are preferably provided with a thickness about equal to the radial dimension of the frangible ribs 24, or the tabs 28 are otherwise configured to collectively define an inside diameter about equal to an inside diameter collectively defined by the ribs 24.
  • the flexible tabs 28 When the closure is fully seated on the container, the flexible tabs 28 have moved past the container locking ring L, and thereafter, due to the resilient memory of the plastic, assume a generally angularly upwardly and inwardly extending disposition, as illustrated in FIGURE 4.
  • the flexible tabs 28 are now in position for the first mode of interfering interaction and failure in cooperation with the container locking ring. Specifically, unscrewing upward movement of the closure 10 relative to the container urges the generally upwardly extending flexible tabs 28 into and against the container locking ring L.
  • This interfering engagement with the container locking ring acts to resist the upward unscrewing movement of the closure, thereby stressing and fracturing the frangible ribs 24. Fracture of the ribs 24 results in clearly visibly discernable separation of the pilfer band 20 from the skirt portion 16, thus providing a clear indication of opening of the container.
  • each flexible tab 28 is of a generally planar configuration having a thickness dimensioned between about 0.305 mm (0.012 inches) and 0.5 mm (0.020 inches).
  • each flexible tab 28 is preferably dimensioned and configured for sufficient thickness, in the direction from its free end to its base integral with the band portion 22, so as to exhibit sufficient resistance to collapse or deformation to thereby provide the desired interfering interaction with locking band L.
  • each of the tabs 28 may be of a non-planar configuration, such as being slightly curved when viewed in cross-section perpendicular to the length of each tab, or similarly, of a generally angled or compound configuration when similarly viewed. As will be appreciated, such arrangements can act to enhance the "column strength" of each flexible tab for providing the desired interfering engagement with locking ring L.
  • the flexible tabs 28 are configured for cooperation with interference bead 30 to provide a second and distinct mode of interfering engagement with the container locking ring L.
  • the flexible tabs 28 In the event that the flexible tabs 28 are moved from their angularly upwardly and inwardly disposition (such as by unauthorized manipulation or the like, which is desirably inhibited by the inwardly extending bead 30) the flexible tabs will assume an angularly downwardly and inwardly extending disposition, as illustrated in FIGURE 5. In this orientation of the tabs, the tabs are positioned for engagement with the container locking ring L by disposition between the container locking ring and the upper inward edge of the interference bead 30.
  • FIGURES 6a and 6b where in FIGURE 6a, a flexible tab 28 is illustrated between the locking ring L and the interference bead 30, with FIGURE 6b illustrating the subsequent failure of frangible rib 24 and separation along score line 26.
  • FIGURE 7 therein is illustrated an alternate embodiment of the present tamper-indicating closure.
  • this embodiment is the same as the previously described embodiment, although it will be noted that the closure illustrated in FIGURE 7 shows the provision of a sealing liner 15 adjacent to top wall portion 14, and a vent groove 17 traversing the internal thread formation 18, with the vent groove 17 extending into the cylindrical skirt portion 16 of the closure.
  • the provision of one or more vent grooves 17 facilitates venting of gas pressure, attendant to closure removal, when the present closure is used in connection with a container having carbonated contents or the like.
  • the closure 10 includes a pilfer band 20 which is distinguished and at least partially separated from the skirt portion 16 by a circumferential score 26.
  • the pilfer band 20 includes a plurality (twelve being presently preferred) of circumferentially spaced, inwardly extending flexible tabs 28, again configured to provide a dual mode of interference with the locking ring of an associated container.
  • an inwardly extending interference bead 30 is positioned beneath the flexible tabs 28, with the tabs 28 being engageable with the interference bead 30 in the second mode of interaction of the closure with an associated container.
  • the frangible connection between the pilfer band 20 and the skirt portion 16 is provided by a plurality of circumferentially spaced, frangible ribs 124 which extend between the inside surfaces of the skirt portion and the pilfer band.
  • frangible ribs 124 extend on the inside surface of the band portion 22 of the pilfer band 20 between adjacent ones of the flexible tabs 28.
  • each of the illustrated frangible ribs 124 is so configured.
  • This configuration of the frangible ribs 124 desirably acts to center the pilfer band 20 on the associated container C with respect to the container locking ring L.
  • This configuration of the frangible ribs 124 a very limited amount of clearance is provided between the container locking ring L and the inwardly facing surfaces of the frangible ribs 124 when the closure 10 is fully seated on the associated container.
  • ribs 124 are rendered fracturable by virtue of the score line 26 partially extending into at least some of the ribs.
  • this embodiment includes a circumferentially extending scoring bead 127 on the inside of the closure, with the scoring bead 127 preferably extending continuously along the inside of the closure, and with circumferential score line 26 positioned beneath the scoring bead.
  • a scoring mandrel inserted into the closure is preferably employed, with a scoring knife or the like then applied to the exterior surface of the closure.
  • a scoring knife or the like it is presently preferred that position of the scoring knife be referenced relative to the interiorly-positioned scoring mandrel.
  • the scoring bead 127 is configured to securely engage and seat against the scoring mandrel, whereby highly efficient and accurate formation of the score line 26, with the desired degree of partial cutting of the frangible ribs 124, is readily accomplished.
  • the flexible tabs 28 are preferably provided with a thickness about equal to the radial dimension of frangible ribs 124. This preferred dimensional relation permits the tabs 28 to desirably support the interior of the closure during scoring (when the tabs 28 are flexed upwardly against the inside surface of the closure) in absence of the scoring bead 127.
  • a further feature of the embodiment of FIGURE 7 concerns the formation of each of the frangible ribs 124 with an upper portion 125 which extends on the inside surface of skirt portion 16 above scoring bead 127.
  • This configuration of the frangible ribs has been found to desirably enhance the columnar strength of the overall closure, which facilitates high-speed ejection from the associated molding apparatus.
  • FIGURE 8 therein is illustrated a further alternate embodiment of the present closure.
  • this embodiment is like that described above and illustrated in FIGURE 7, although the embodiment of Figure 8 does not include a scoring bead 127.
  • the absence of the scoring bead, together with the extended configuration of frangible ribs 124 (with upper portions 125) can enhance the gas venting characteristics of the closure.
  • this embodiment of the present tamper-indicating closure includes an arrangement for prestressing the frangible connection between the pilfer band 20 and the skirt portion 16 provided by the frangible ribs 124.
  • a plurality of circumferentially spaced, prestressing projections 131 are provided on the inside surface of the band portion 20 of the pilfer band.
  • these prestressing projections 131 are each positioned on a respective one of the frangible ribs 124.
  • the prestressing projections 131 are provided on alternate ones of the frangible ribs 124, but a fewer or greater number of the projections 131 can be similarly provided.
  • Projections 131 can be provided to prestress the frangible ribs 124 attendant to both application and removal of the closure. During application of the closure to the associated container, the projections 131 are engageable with the container locking ring L, thus acting to expand and "bell out” the pilfer band 20 attendant to application. This action can act to weaken the unscored, residual portion of each frangible rib 124, thereby facilitating failure of the frangible ribs in the intended manner during closure removal.
  • the prestressing projections 131 can cooperate with the locking ring L during closure removal. In particular, this can occur in conjunction with stressing and fracture of the ribs 124 when tabs 28 extend angularly downwardly, and are positioned between the container locking ring L and interference bead 30. Attendant to this action, the projections 131 provide additional interference with the container locking ring, thus desirably subjecting the frangible ribs 124 to additional stress to assure fracture and failure of the ribs.
  • a further feature of the embodiment of FIGURE 8 concerns configuring the pilfer band 20 for fracture of the band portion 22, which is ordinarily desired, as discussed above, in conjunction with the provision of an unscored connector portion which integrally joins the pilfer band to the skirt portion 16 after fracture of ribs 124. By such an arrangement, the pilfer band remains joined to, but partially detached from, the skirt portion 16.
  • FIGURE 8 illustrates the manner in which a vertical score is preferably formed in the pilfer band 20.
  • an external scoring knife is preferably applied to the pilfer band so as to form one or more scores extending to a depth as illustrated in phantom line at 133.
  • such vertical scoring is provided between one of the flexible tabs 28 and an adjacent frangible rib 124, so that such vertical scoring does not extend into either the tab 28 or the rib 124.
  • the vertical scoring extend partially, but not completely, into the interference bead 30, to thereby define a fracturable residual portion 135 of the pilfer band.
  • This arrangement preserves a desired degree of strength in the pilfer band, to facilitate high-speed application, while still rendering the pilfer band fracturable in the intended manner.
  • the present closure a high degree of tamper-resistance is provided by the present closure.
  • various modifications and departures from the illustrated embodiment can be effected.
  • the number, spacing, thickness, and configuration of the flexible tabs 28 can be varied and selected while keeping with the principles disclosed herein.
  • the annular interference bead 30 is preferably substantially continuous in nature for providing additional circumferential hoop strength for the closure, segmented or otherwise discontinuous configurations for the interference bead can be alternately employed.
  • a closure embodying the present invention may be composite in nature, such as a combination metallic and plastic closure (with or without a separate sealing liner).
  • this plastic closure 10 includes a cup-like closure cap 12 having a circular top wall portion 14, and a depending annular or cylindrical skirt portion 16 having an internal thread formation 18.
  • closure 10 is intended to be applied to an associated container C having an external bead-like locking ring L which extends circumferentially of the neck portion of the container perpendicular to the vertical axis thereof.
  • Locking ring L is positioned just beneath external container threads T, with the container C including a hand grip or handle H.
  • the closure includes an annular pilfer band 20 depending from skirt portion 16 which is at least partially detachably connected to the skirt portion by a plurality of circumferentially spaced apart fracturable bridges 22.
  • the fracturable bridges can alternately be provided generally along the inner surfaces of the pilfer band and skirt portion, such as disclosed in U.S. Patent No. 4,418,828.
  • Pilfer band 20 includes an annular, bead-like interference lip 24 extending circumferentially about the inner surface of the pilfer band 20.
  • interference lip 24 does not extend perpendicularly to the vertical axis of closure 10, but rather extends in a plane arranged at an acute angle relative to the vertical axis of the closure. In the preferred form, this plane is arranged at an acute angle in the range of about 1 degree to about 5 degrees relative to the closure axis.
  • the interference lip as shown is extending continuously about the inner surface of the pilfer band 20, it should be recognized that the lip 24 may be otherwise configured, so as to extend discontinually about the inner surface such as by the provision of a series of segments, lugs, or like projections. Whether the interference lip 24 is of a continuous or discontinuous configuration, it is contemplated that the lip extends in a skewed or non-­perpendicular relationship to the vertical axis of the closure.
  • this non-uniform stressing desirably results in the deformation of the pilfer band 20 to an out-of-round, non-circular configuration, i.e., to a generally elliptical or oval shape.
  • This deformation in the pilfer band facilitates movement of the interference lip past the locking ring L during application of the closure to the container, thereby reducing the force required for application and minimizing stresses created on fracturable bridges 22.
  • the interference lip 24 again cooperated with the container locking ring L to create a non-uniform stressing of the pilfer band 20, and in particular provide a progressive stressing of fracturable bridges 22.
  • a plurality of circumferentially spaced centering ribs 26 are provided on the inside surface of pilfer band 20 above interference lip 24. Centering ribs 26 are positioned to engage the container locking ring L during closure removal, and thus maintain the pilfer band in a circular configuration.
  • centering means can be employed, such as by the provision of a continuous ring on the interior of the closure, or by the provision of an area of relatively reduced inside diameter just above the interference lip.
  • a centering arrangement be provided for engagement with locking ring L as the interference lip 24 engages the locking ring, to thereby prevent the pilfer band from assuming a non-­circular configuration, thus assuring the intended fracture of bridges 22.
