Definitions

  • the present invention relates to a container closure.
  • the invention relates to a screw cap for a wine bottle.
  • the invention also relates to a container and closure combination as well as to a container per se. While the invention is particularly described herein in the context of wine bottle closures, the invention is not limited thereto and may encompass any other type of closure for a container.
  • Corks are being gradually replaced by screw caps as shown in Figure 1.
  • screw caps comprise an upper cap portion frangibly connected to a lower skirt.
  • the upper cap portion is threadedly engaged with the top of the bottle.
  • the bottle also has a circumferential bead positioned in the region of the skirt.
  • the skirt is deformed so as to form a depression known as a 'tuck under' below the circumferential bead. This holds the screw cap in place until the cap portion is twisted off, thereby severing the frangible connection.
  • the depression is generally applied by metal rollers during the bottling procedure. There are difficulties associated with forming this depression.
  • bottles may be selected for testing, after which the bottles need to be returned empty and capless for refilling and recapping. Additionally, during bottling, errors may occur and since the bottling procedure takes place at a fast rate, some thousand bottles may be filled and bottled before the error is detected. These bottles need to be uncapped, emptied and the skirt removed and then returned for rebottling.
  • a container and closure combination including: a container having a central axis and an open end; and a closure covering said open end and having dependent sides, wherein the container has integrally formed first engagement means and the closure has second engagement means, the first and second engagement means mutually engaging to retain the radial position of at least a portion of the closure relative to the container.
  • the first engagement means are preferably disposed on the external side of the container.
  • the first engagement means may be integrally formed on the exterior of the neck of the bottle.
  • the second engagement means may be disposed on the dependent sides of the closure.
  • the first engagement means may comprise one or more projections extending from the surface of the bottle.
  • the second engagement means may comprise one or more dimples/depressions/flutes/corrugations configured to engage with the one or more first projections to retain the radial position of at least a portion of the closure.
  • the first engagement means may comprise depressions in the container and corresponding depressions in the closure which are seated in the depressions in the container.
  • the second engagement means on the closure are formed through the thickness of the closure which may be comprised of metal especially aluminium sheet material.
  • the second engagement means may be arranged in a ring on the dependent sides of the closure.
  • the second engagement means may comprise evenly spaced dimples of uniform depth arranged in a ring.
  • the first engagement means may also be arranged in a ring.
  • the first engagement means need not be uniformly spaced, especially since they are not visible to the purchaser.
  • there may be diametrically opposed zones which are free of projections in order that the standard width of the bottle neck is not exceeded so that existing bottling equipment is able to accommodate the new container.
  • first and second engagement means are not limited to being arranged in corresponding rings.
  • the second engagement means may be arranged in any kind of pattern on the dependent sides of the closure with the first engagement means arranged in a corresponding pattern, provided that when mutually engaged, the first and second engagement means retain the radial position of at least a portion of the closure relative to the container.
  • the arrangement of the first and second engagement means permit easy removal of at least said portion the closure, preferably in a direction parallel to the central axis of the container.
  • the closure may be in the form of a cap portion and a dependent skirt wherein the cap portion and the dependent skirt are frangibly connected.
  • the second engagement means may be formed in the dependent skirt (which comprises said portion) with the first engagement means formed on a corresponding part of the container.
  • the cap portion may comprise a screw cap.
  • the threads are formed through the thickness of the cap portion.
  • the threads may be formed during the bottling procedure.
  • a mating thread may be integrally formed on the exterior surface of the container to matingly engage with the thread in the cap portion. While threaded engagement is the preferred form of the invention, other twist action engagements may be provided between the cap portion and the container.
  • the mating engagements may define a bayonet-like closure.
  • a compressible seal gasket is provided between the opening of the container and interior of the closure.
  • the container may also comprise stop means downwardly spaced from the first engagement means. Once the cap portion has been disconnected from the skirt by unscrewing the cap portion, the skirt may then drop until the second engagement means abuts against the stop means. This provides tamper evidence so that even if the cap portion is rescrewed onto the container, the gap between the top of the skirt and the bottom of the cap portion will provide evidence of opening.
  • the stop means may be in the form of a circumferential ridge or bead and is desirably integrally formed on the external surface of the container.
  • the cap portion and the skirt are preferably substantially separated with remaining interconnections able to be easily broken.
  • evenly spaced bridges may extend between the cap portion and the skirt.
  • An overcap may be provided to extend over at least part of the closure.
  • the overcap extends over the cap portion to cover the threads.
  • the overcap may engage with the threads so as to lock onto the threads so that the cap portion and overcap may be removed together.
  • the overcap has a left hand thread while the cap portion has a right hand thread.
  • a closure for a container having an opening and a central axis
  • the closure including: an upper portion for covering the opening; and a dependent skirt frangibly connected to the upper portion, wherein the skirt is provided with engagement means adapted to engage with the container to retain the radial position of the skirt relative to the container.
  • the engagement means may serve to retain the radial position of the skirt relative to the container during storage and when removing the upper portion.
  • the upper portion is in the form of a screw cap, the threads of which are formed through the thickness of the cap during the bottling process.
  • a container for use with a closure having an opening and central axis, the container further provided with integrally formed engagement means to engage with at least a portion of the closure to retain said portion in a relative radial position.
  • the container is in the form of a bottle and the engagement means are formed in the external surface on the neck of the bottle.
  • a fourth aspect of the invention there is provided a method of forming the container and closure, the method comprising:
  • first and second engagement means mutually engage to retain the radial position of at least a portion of the closure relative to the container.
  • This invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more of said parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which this invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.

  • Figure 13 is a second embodiment of the overcap of Figure 11 .
  • Figure 2 shows the neck 20 of a container in the form of a bottle having an upper opening 22 and a central axis 24.
  • the upper end of the neck 20 is integrally formed with external threads 26 and a series of spaced projections 28 arranged in a ring.
  • the projections 28 are in the form of short ridges having a lengthwise direction parallel with the central axis 24.
  • the ring of projections 28 is formed integrally in the surface of the bottle below the threads 26. Below the ring of projections 28 is a circumferential bead 30, the function of which will be explained subsequently.
  • Figure 3 illustrates the arrangement of projections 28 about the circumference.
  • the projections 28 are irregularly spaced but are disposed at intervals of 11.25 degrees or a multiple thereof as depicted in figure 3.
  • Figure 10 illustrates a closure in the form of a cap 40 for use with the bottle illustrated in figure 2.
  • the cap 40 is formed of a low strength metal such as aluminium or alloys thereof.
  • the cap 40 is comprised of a cap portion 42 and a skirt 44.
  • the cap portion 42 and the skirt portion 44 are frangibly connected by means of frangible bridges 46 as is already known in the art.
  • the screw cap 40 is shown in its pre-used configuration.
  • the cap 40 is drawn onto the neck 20 of the bottle.
  • threads (not shown) are formed on the cap portion 42 which are threadedly engageable with threads 26 on the neck of the bottle 20.
  • the threads on the cap 40 are created by the drawing process which presses the metal of the cap into the threads 26 on the bottle and thus creates mating threads.
  • the cap 40 has a ring of dimples 48 arranged at the top of the skirt 44.
  • Each of the dimples is formed through the thickness of the skirt 44 to form a ring of projections internally of the skirt 44.
  • the dimples 48 and corresponding projections on the interior of the skirt have a lengthwise direction which is parallel to central axis 24.
  • the cap 40 is placed on the neck 20 of the bottle.
  • the dimples 48 overlap with the projections 28 for approximately half their length.
  • the projections 28 are fully engaged between the dimples 48. This allows a clearance of approximately 1.5mm between the bottom of the dimples 48 and the bead 30 (see of figure 5).
  • rollers are used to form the depression defining the tuck-under.
  • Such bottling equipment may be adapted to substitute rubber rollers for the metal rollers so that the rubber rollers now roll over the ring of dimples 48 to thereby bring the dimples 48 and the projections 28 into closer engagement.
  • the cap portion 42 When it is desired to open the bottle, the cap portion 42 is unscrewed thereby severing the frangible connection between it and the skirt 44. Meanwhile, the skirt 44 is held in its radial position by the interengagement of dimples 48 and projections 28. Alternatively, the frangible connection may be broken simply by pulling down the skirt 44 until the dimples 48 abut on the top of the circumferential bead 30. In any case, it is preferred that the fit between the skirt 44 and the external surface of the bottle is such that the skirt 44 is permitted to drop once the frangible connection is severed. Thus, even if the cap portion 42 is replaced there will be a gap between the top of the skirt 44 and the bottom of the cap portion 42 evidencing that the bottle has been opened.
  • Tape may be provided to cover the circumferential ring of dimples 48 if required.
  • Another advantage of the particular configuration of the neck 20 is that the bottle may still be used with an existing prior art closure as shown in figure 1.
  • Another advantage of the present invention is that less mechanical operations are required in the bottling procedure than with the prior art screw cap shown in figure 1.
  • an overcap 50 may be provided to extend over the cap portion 42 as shown in Figure 11 .
  • the overcap 50 covers the threads and extends to just above the ring of dimples 48. Two different forms are shown in Figures 12 and 13.
  • a plastic overcap 50b is provided having internal threads 52 which are in a left hand direction.
  • the threads which are formed through the thickness of the cap portion 42 extend in a right hand direction.
  • the threads 52 therefore lock onto the threads of the cap portion 42.
  • the plastic overcap 52 is applied by being pushed over the cap portion 42. When it is desired the remove the cap portion 42 and the overcap 50, they are unscrewed together.
  • the overcap 50a is comprised of an aluminium outer 54 with rubber gasket material 56. The overcap 50a grips onto the cap portion 42 for removal therewith.
  • overcaps 50a and 50b provide improved seal protection, especially when wine bottles utilising the caps are stacked one atop the other. Commonly, wine bottles may be stacked 3 or 4 bottles high in a pallet. Uneven stacking may lead to damage to the caps and the overcaps provide additional protection against this. Further, the overcaps provide an improved appearance by hiding the screw threads.
