Definitions

  • This invention relates to container closures, and is particularly, but not exclusively, concerned with so called 'tamper-evident' closures.
  • 'closure' is used herein to embrace any form of cover, or termination, such as to a container access aperture, or mouth.
  • 'tamper-evident' is generally used to designate container closures, such as screw caps, which - once installed upon a container - cannot be removed, without some form or other of '(self-) evident', or apparent, visual indication.
  • the indication is by the fracture, breakage, severance, removal, absence, or otherwise interference with, some part of the closure.
  • Tamper-evident closures may, or may not, also be 'tamper-resistant' - that is with some ancillary provision to deter casual opening, by the uninitiated, or unauthorised.
  • Child-resistant containers say, for pharmaceuticals, are a case in point.
  • Tamper-evident container closures provide some visible indication that the container may already have been opened, or that the contents have been accessed - after original filling and closure installation.
  • Consumable products such as drinks, foodstuffs, and pharmaceuticals, are particularly vulnerable.
  • consumer reassurance is engendered, over a disparate variety of products, by the visible presence of an unbroken, or intact, closure 'seal' - as signifying that the full, unadulterated, original contents remains intact.
  • a common tamper-evident implementation is configured as a peripheral, or boundary, strip seal, such as a part-closed, annular ring, with an end pull-tab - which is visible and readily apparent.
  • a closure It is generally desirable for a closure to be initially entrained, or captured, with a container, to inhibit inadvertent dis-lodgement, loosening or removal.
  • the cap retention lip may be carried by a removable tamper evident strip - itself connected to a closure body, by a locally weakened marginal periphery, of, say, reduced wall thickness.
  • Strip separation by fracture of the weakened margin, allows a remaining upper portion of the cap to be removed, and the container to be opened.
  • Tamper-evident (TE) container closure caps with retention bands or rings are known, but can prove (unduly) complex in form - with an inherent fragility in the mutual entrainment of retention ring and cap proper - and so difficult to manufacture, by say moulding.
  • PCT WO 96/31404 (Crown Cork) employs a TE retention band of significantly reduced radial wall thickness or depth than an upper closure cap portion - with precariously fragile mutual entrainment. Moreover, a lower depending rim of the cap marginally overlies an upper rim of the TE band.
  • Cap installation requires flexing of a TE band inturned edge over a container neck retention ring - imposing stress upon the fragile mutual entrainment. Thus, the demands placed upon the mould tool and moulding process are severe. The cap remains vulnerable, so careful inspection would be required to ensure an intact cap structure before installation.
  • PCT WO 98/22361 (Crown Cork) is concerned with a depending cap retention ring having a complex, multiple-concavity, profiled rim - with the intention of enhancing resistance to longitudinal pulling force in attempted cap removal without TE band fracture.
  • the profiled rim is in-turned from a thicker annular TE band, itself offset in relation to an upper cap portion. Again, mutual entrainment of cap and TE band is localised and fragile.
  • the mould tooling required would be complex and costly to machine and the moulding process critical to achieve a clean product profile.
  • a disadvantage of a conventional approach to tamper evidence is that moulding tolerances can allow a 'slack', loose or sloppy, inter-fit between a closure cap and a container neck.
  • respective complementary threads upon adjacent boundary walls, may not co-operatively inter-nest as snugly as they might.
  • This tolerance can be such that distortion of the cap (from, say, circular to oval section) - by say squeezing its sides upon manual gripping - is sufficient to allow a cap retention lip to ride (locally) over a retention rim upon the container neck.
  • a container closure cap incorporates a depending lower edge rim, configured for co-operative interaction, [and entrainment] with, [or capture by], an upstanding retention rim, upon a container neck, upon in-turn, inversion, or reverse-folding, [before or upon installation], creating a (resiliently-deformable), inwardly-protruding (locating and retention) lip.
  • a resilient cap (retention) lip so configured remains operative, even if the cap is distorted - say, by squeezing from opposite sides in a gripping action, between finger and thumb of the hand.
  • the lower cap edge can initially be moulded integrally in alignment with the peripheral cap wall - effectively as an edge extension lip, or rim, to a circumferential peripheral side wall.
  • This edge extension is then reverse-turned inwardly, as a follow-up step to the original moulding - for example by profiled (insertion) die tooling.
  • a fold line, of reduced local wall thickness, can be employed to facilitate in-turning of the cap wall edge.
  • Entrainment of a closure to a container is achieved by entrapment of the in-turned lip, 'beneath' a retention ridge or rim upon the container neck.
  • the inverted cap edge may be continuous or discontinuous.
  • the edge could be segmented into a plurality of discrete tabs.
  • Such tabs could also selectively inter-fit with complementary grooves in the container neck - allowing the tabs to penetrate into the neck wall thickness and require even greater displacement for cap removal.
  • a closure cap may be of generally even wall thickness or depth, except for: a marginal end rim, deformable as an in-turned step, and: a marginal locally waisted portion, of circumferentially-spaced recesses, accommodating retention tabs or tongues, as a division between cap portions.
  • Such a closure cap may embody a (contiguous) inner wall, along a common diameter, between cap portions.
  • a closure cap may incorporate a plurality of circumferentially-spaced recesses, each with a stepped profile, both in radial depth, and circumferential extent or span, to form an inset ledge, with opposed lateral shoulders or abutments, upon each side of an interconnecting tab or tongue, spanning cap portions, the shoulders being marginally spaced from the tab, to allow limited relative circumferential displacement, upon relative twisting of cap portions, until contact between abutment and tab resists further lateral tongue flexing or distortion.
  • a container closure cap may be of generally cylindrical form, with a curved peripheral wall, depending from a flat top or cap, the wall incorporating a peripheral waisted portion, of locally reduced radial depth, and dividing the cap into upper and lower portions, the upper portion having an internal thread, the lower portion being unthreaded, a plurality of circumferentially-spaced tongues, mutually entraining the portions, the tongues being disposed in recesses, profiled to allow limited lateral tab displacement, until contacting an abutment at the recess edge, which inhibits lateral tab displacement, so that further twisting severs the tongue, and uncouples the upper and lower portions .
  • Figures 1A through 1F show a (screw) closure cap, for a container (not shown), incorporating a resiliently deformable, reverse-fold, in-turned retention lip, according to the invention
  • a tamper-evident closure is configured as a generally cylindrical, open ended, (screw) cap 10.
  • the cap 10 has a serrated, or multiple-ribbed, outer circumferential wall 13, to facilitate manual gripping - for rotary threading upon installation and removal.
  • the inner cap wall carries an integral thread 11, for co-operative inter-fit with a complementary thread 19 upon a cylindrical neck 31 of a container 30.
  • the cap 10 is divided into a mutually-severable (upper) portion 12 - with the serrated rim 13, and internal thread 11, and a lower portion 14 carrying an inward retention lip 18.
  • the cap retention lip 18 is configured for co-operative interaction with an (in this example continuous) upstanding retention ridge, ledge or rim 32, upon the outer circumference of the container neck 31.
  • the upper cap portion 12 is configured as a cylinder, with one end closed - and so, when fitted to the container neck 31, covers the otherwise open mouth of the neck.
  • a separate seal may be located between cap and neck rim, to inhibit contents leakage.
  • the lower cap portion 14 is configured as an open annular ring, and effectively constitutes a peripheral tamper-evident strip 15.
  • the upper and lower cap portions 12, 14 are mutually entrained, in an assembled cap condition, by a series of frangible tabs 21, more readily discernible from the enlarged views of Figures 1E and 1F.
  • the tabs 21 are sufficiently robust to withstand:
  • the tabs 21 must be fractured or broken, once the cap 10 is installed upon the container neck 31, for separation from the upper portion 12.
  • a lateral recess 23 in the cap wall allows a certain circumferential movement - and stretching to ultimate yield failure - of an associated tab 21.
  • the recess 23 partially enshrouds the tabs 21 and protects them from inadvertent contact damage
  • Profiling such as radiusing and waisting of the tab 21 and lateral shoulders 24, promotes the requisite (progressive) lateral displacement and eventual severance action.
  • the upper cap portion 12 is freely rotatably - in one direction, away from the retention rim 32.
  • the 'tamper-evident' strip 15 remains 'permanently' in place, entrained by the retention rim 32-albeit not necessarily still attached to the upper cap portion 12.
