- FIG. 7 is a cross-sectional view of the closure system taking along lines VII - VII of Figure 1.
- a closure system embodying the present invention may take the form of a fitment 10.
- the fitment 10 comprises a neck portion 12, a cap portion 14 and, between the two, a transition member 16 which joins the neck portion 12 to the cap portion 14.
- the neck portion 12 comprises an apertured flange 18 having substantially smooth and planer upper and lower surfaces 20 and 22 respectively.
- a cylindrical wall 24 projects upwardly from the upper flange surface 20 to form the neck. Adjacent to the flange 18, the external surface of the cylindrical wall 24 is smooth before merging with a radially outwardly projecting locking wall 26 to define a shoulder.
- the locking wall 26 At an end of the locking wall 26 remote from the cylindrical wall 24, the locking wall 26 in turn merges with an upwardly and radially inwardly inclined surface 30 which, with the radially outwardly projecting locking wall 26, defines an annular locking bead 32. Above the annular locking bead 32, the upwardly and radially inwardly inclined surface 30 merges with a neck stretch portion 34 of slightly increased diameter compared to the cylindrical wall 24 in which is provided engagement means with which to engage complimentary engagement means provided on the cap portion 14.
- the engagement means provided on the neck stretch portion 34 takes the form of an equi-spaced, multi-lead female helical thread configuration 36 which includes four threads or leads 36a, 36b, 36c and 36d.
- each thread 36a, 36b, 36c and 36d extends about 120° around the circumference of the neck stretch portion 34.
- threads of a lesser or greater extent may also be employed.
- each thread 36a, 36b, 36c, 36d may extend within a range from 90° to more than 360°.
- the helical thread configuration 36 has a fine thread density to limit the vertical float of the cap portion 14 on the neck portion 12.
- the thread density preferably lies within a range of between 6 and 12 threads per linear inch. Most preferably of all, is a thread density of approximately 8% threads per linear inch.
- the neck stretch portion 34 merges with a second upwardly and radially inwardly inclined surface 38 which in turn merges with a further vertical neck stretch portion 40 before terminating in an annular rim 42.
- the annular rim 42 merges with a downwardly and radially inwardly inclined surface 44.
- This downwardly and radially inwardly inclined surface 44 in turn merges with a substantially smooth inner surface 46 of the cylindrical wall 24.
- the substantially smooth inner surface 46 flares radially outwardly adjacent the flange 18 to define a downwardly and radially outwardly inclined surface 48.
- the cap portion comprises a circular top 52 having an under surface 54.
- the circular top 52 merges at a radially outer edge with a downwardly and radially outwardly inclined surface 56 which in turn merges with a depending annular side wall 58 to form a downwardly extending upper skirt portion 60.
- the depending annular side wall 58 is provided on an inner surface 62 with complimentary engagement means for repeated and releasable engagement with the engagement means provided on the neck portion 12.
- these engagement means may take many forms but, in the example shown, comprise an equi-spaced, multi-lead, male helical thread configuration 64 having four threads or leads 64a, 64b, 64c and 64d and a thread density of approximately 8% threads per linear inch.
- each thread extends approximately 120° around the inner surface 62 of the depending annular side wall 58.
- this thread length may be increased or decreased if desired.
- each thread may extend in a range from 90° to more than 360° .
- the thread density is not intended to be limited to being about 8% threads per linear inch but, nevertheless, preferable lies within the range from about 6 to about 12 threads per linear inch.
- the female thread configuration 36 on the neck portion 12 and the male thread configuration 64 on the cap portion 14 each have at least two threads and a thread density of at least 6 threads per linear inch.
- the male threads 64a, 64b, 64c and 64d provided on the cap portion 14 may be interrupted at intervals along their length.
- the threads of the male helical thread configuration 64 may be provided with an appropriate cross-sectional shape.
- the threads may be formed with an asymmetric cross-section or else may be made less pronounced.
- the two thread configurations 36 and 64 each comprise multiple turns of thread.
- a vertical line drawn across the thread configuration 36 on the neck portion 12 intersects two or three turns of thread depending upon the location of the line around the circumference of the neck stretch portion 34.
- a vertical line drawn across the thread configuration 64 on the cap portion 14 intersects one or two turns of thread depending upon the location of the line around the circumference of the depending annular side wall 58. This ensures that when the cap portion 14 is applied to the neck portion 12 there will be multiple turns of thread engagement.
- the total cumulative thread engagement is subject to variation and, depending upon the linear thread density, may be as little as one turn of thread engagement or more than three turns of thread engagement .
- the interior of the cap portion 14 is provided with an annular plug 66 which depends from the under surface 54 of the circular top 52 and which is spaced radially inwardly of the depending annular side wall 58.
- the annular plug 66 is defined by respective radially inner and outer walls 68 and 70, the radially outer plug wall 70 merging at an end remote from the circular top 52 with a generally downward and radially inwardly directed surface 72.
- This downwardly and radially inwardly directed surface 72 intersects the radially inner plug wall 68 and together serves to provide the annular plug 66 with a bevelled radially outer surface and a tapering cross-section.
- the depending annular side wall 58 is provided on its outer surface with a plurality of circumferentially spaced, vertical extending ribs 74 which serve as knurls to facilitate the gripping of the cap portion 14 by a user.
- a small downwardly directed dimple 76 is formed in the centre of the circular top 52 so that any flash left after the cap portion has been moulded does not project above a plane defined by the upper surface of the circular top 52.
- the cap portion 14 is provided with an annular band 78 which is formed as an extension of the depending annular side wall 58 at a position remote from the circular top 52 and beneath the male helical thread configuration 64.
- the exterior surface of the annular band 78 occupies an extension of the same cylindrical surface as that defined by the exterior surface of the depending annular side wall 58.
- the inner surface 62 of the depending annular side wall 58 merges, via a short downwardly and radially outwardly inclined surface 80, with an inner band surface 82 of slightly greater inner diameter.
- the inner band surface 82 merges with the exterior band surface via a radially outwardly directed rim 84. Both the inner and exterior surfaces of the annular band 78 are formed free of projections so as to be substantially smooth.
- the annular band 78 is delimited from the depending annular side wall 58 by a plurality of arcuate slits 86 which are circumferentially spaced at intervals around the cap portion 14 and in the same horizontal plane. As a result the spacings between the arcuate slits 86 define a plurality of circumferentially spaced tabs 88 by which the annular band 78 is connected to the depending annular side wall 58. At opposite ends of each of the arcuate slits 86, the slits open out into apertures 90 of increased cross-section, thereby weakening the area on either side of each of the tabs 88.
- the cap portion 14 is initially joined to the neck portion 12 by means of transition member 16.
- the transition member 16 comprises a downwardly and radially inwardly inclined frustoconical wall which is provided with a plurality of trapezium-shaped apertures 92 which serve to define therebetween a similar number of transition elements 94.
- Each transition element 94 lies within a frustoconical surface and has an upper circumferential dimension adjacent the annular band 78 which is greater than a lower circumferential dimension adjacent the neck portion 12.
- each transition element 94 is joined to the annular band.78 by a thin, upwardly and radially outwardly inclined web
- each transition element 94 which merges with the annular band 78 at the intersection of the inner surface 82 and the radially outwardly directed rim 84.
- the inner surface of each transition element 94 is bevelled with the result that each transition element tapers to an edge 98 and it is at this edge 98 that the transition element 94 merges with the neck portion 12 at the intersection of the annular rim 42 and the downwardly and radially inwardly inclined surface 44.
- the closure system herein described may be moulded in one piece with the neck portion 12 integrally formed and joined with the transition member 16 and with the transition member integrally formed and joined with the cap portion 14.
- an axially downwardly directed force is applied to the cap portion in a direction towards the neck portion 12.
- the closure system in the orientation shown in Figure 1, it will be understood that as the cap portion 14 moves downwardly under the action of the applied force so the plurality of transition elements 94 begin to hinge about their respective tapered edges 98.
- the transition elements 94 also flex with respect to the annular band 78, the flexure being accommodated by the initially upwardly and radially outwardly inclined webs 96.
- the transition elements 94 fold upwards into the annular band 78 with the consequence that, as the radially outwardly directed rim 84 passes over the further vertical neck stretch portion 40 followed by the neck stretch portion 34, the transition elements 94 take up an orientation in which they extend from the annular rim 42 of the neck portion to the annular band 78 in a downward and radially outward direction.
- the transition elements 94 ride over the neck stretch portion 34 and the female helical thread configuration 36 until such time as the now downwardly and radially outwardly inclined webs 96 encounter the upwardly and radially inwardly inclined surface 30 of the cylindrical locking wall 24.
- the male threads of the helical thread configuration 64 provided on the cap portion 14 encounter the second upwardly and radially inwardly inclined surface 38 which constitutes the transition between the neck stretch portion 34 and the further vertical neck stretch portion 40.
- the end of the annular plug 66 remote from the circular top 52 is received within the annular rim 42.
- the slight radially outward flexing of the annular band 78 coincides with the slight radially outward flexing of the upper skirt portion 60 as the male helical thread configuration 64 slides over and into engagement with the female helical thread configuration 36.
- the annular plug 66 is received within the bore of the neck portion 12 defined by the substantially smooth inner surface 46. In so doing the generally downward and radially inwardly directed surface 72 slides along the downwardly and radially inwardly inclined surface 44 causing the annular plug 66 to flex slightly radially inwardly.
- the restoring force inherent in the resilient nature of the design and materials making up the annular plug 66 causes the radially outer plug wall 70 to be urged into sealing engagement with the substantially smooth inner surface 46.
- the interaction between the annular plug 66 and the substantially smooth inner surface 46 constitutes a primary seal.
- a secondary seal is provided in the assembled condition by the receipt of the annular rim 42 within the annular recess defined between the radially outer plug wall 70 and the downwardly and radially outwardly inclined surface 56 of the cap portion 14.
- the radially outwardly inclined surface 56 is forced to flex slightly radially outwardly with the result that the restoring force holds the radially outwardly inclined surface in sealing engagement with the annular edge defined by the intersection of the annular rim 42 and the further vertical neck stretch portion 40.
- the fitment 10 may be applied to a paperboard or other carton in the conventional manner.
- the flared opening to the neck portion 12 defined by the downwardly and radially outwardly inclined surface 48 facilitates the insertion of a spud of a manipulation tool .
- the provision of the plurality of circumferentially spaced, radially inwardly projecting lugs 50 facilitate the retention of the fitment on the spud. Since the apertured flange 18 has substantially smooth and planar upper and lower surfaces 20 and 22, the fitment 10 may be bonded either to the outside or to the inside of a carton panel as desired.
- the neck portion 12 may be provided with one or more additional projections which cooperate with the apertured flange 18 to retain the fitment 10 in a specific orientation with respect to the carton panel to which the fitment is to be attached.
- the cap portion 14 In the assembled condition the cap portion 14 is prevented from being removed from the neck portion 12 in an axial direction by the interengagement of the male and female helical thread configurations 64 and 36 and by the engagement of the tapered edges 98 with the annular locking bead 32.
- a user In order to remove the cap portion therefore, a user is required to rotate the cap portion 14 with respect to the neck portion 12. This causes the threads of the male thread configuration 36 to rise up the grooves of the female thread configuration 36 bringing the tapered edges 98 more firmly into engagement with the locking wall 26.
- the cap portion 14 may be reapplied and subsequently removed from the neck portion 12 as often as it is desired.
- the tear-band in the form of annular band 78 and transition elements 94
- the tear-band remains in place on the neck portion 12 beneath the locking wall 26.
- all that is required is to elongate the portion of the cylindrical wall 24 between the apertured flange 18 and the radially outwardly projecting locking wall 26.
- the transition elements 94 In order to facilitate the extraction of the core it has also been found preferable for the transition elements 94 to be inclined radially outwardly at an angle of between 22° and 32° to the vertical, and most preferably, at an angle of 27° to the vertical.
- the vertical distance between the radially outwardly directed rim 84 and the annular rim 42 is preferably 3.5mm while the tapered edge 98 preferably has a radial dimension of between 0.16mm and 0.10mm.
- the transition elements 94 preferably have a dimension at right angles to the angle of inclination of 0.5mm.
- each group of three trapezium-shaped apertures 92 are preferably symmetrical about a vertical centre line with the central trapezium-shaped aperture having an upper circumferential dimension adjacent the annular band 78 of 2mm and the two mutually inclined sides of the aperture subtending an angle of 30°.
- the trapezium-shaped apertures on either side are preferably spaced 6.2mm from the centre line and arranged so as to have an upper circumferential dimension adjacent the annular band 78 of 1mm while the mutually inclined sides of the apertures subtend an angle of 25°.
- the two trapezium-shaped apertures 92 spaced on either side of the central aperture within each group of three are preferably not themselves symmetrical. Rather, the inclined edge of the two side apertures closest to the central trapezium-shaped aperture preferably subtends an angle of 20° with respect to the centre line. In this way each transition element 94 has an upper circumferential dimension adjacent the annular band 78 which is greater than its lower circumferential dimension adjacent the neck portion 12.
- the annular band 78 has a vertical dimension from the short downwardly and radially outwardly inclined surface 80 to the radially outwardly directed rim 84 of 4.55mm with the distance from the short downwardly and radially outwardly inclined surface 80 to the arcuate slits 86 accounting for 0.5mm of that vertical dimension.
- the slits 86 preferably have a vertical dimension of 0.25mm and open out into apertures 90 having a vertical dimension of 0.85mm.
- the arcuate slits 86 are preferably formed using slides that open and close at right angles to the male and female halves of the mould tool. The arcuate slits 86 are therefore preferably formed so as to have no undercuts in the direction of movement of the slides.
- the surfaces joining the circumferential outer surface of the annular band 78 to the inner band surface 82 do not extend radially but rather have the configuration shown in Figure 7 in which the surfaces on either side of one of the tabs 88 subtend an angle of 135° while those at opposite ends of one of the arcuate slits 86 subtend an angle of 92°.
- the tabs 88 fracture reliably they are preferably circumferentially spaced at intervals of 45° and have a radial dimension of 0.25mm.
- the apertures 90 on either side of each of the tabs 88 are preferably dimensioned so that an arcuate slit 86 joining two such apertures has a circumferential dimension of 7.0mm.
- the cap portion 14 is held in fixed relationship with the neck portion 12 prior to application of the cap portion to the neck portion.
- suitable alignment of the thread configurations 36 and 64 to ensure that once the cap portion 14 has been applied to the neck portion 12 the threads are optimally engaged.
- no subsequent tightening of the cap portion 14 is required thereby simplifying the capping process in comparison with the processes of the prior art .
- the optimization of the thread engagement means that the closure system may utilise the minimum thread length commensurate with the sealing properties required, thereby enabling savings in both cap and neck height.
- the optimization of the thread engagement also serves to eliminate any vertical float of the cap portion 14 on the neck portion 12 which would otherwise have to be allowed for in the vertical distance between the annular locking bead 32 and the apertured flange
- the closure system can be designed so that the transition elements 94 engage with the locking bead 32 almost immediately upon unscrewing of the cap portion 14, thereby rendering the closure system more secure against unwanted tampering as well as cheaper to manufacture .
