Definitions

  • the present invention relates to the capping of bottles, and in particular to the use of crown closures.
  • Such closures are long established for the capping of glass and, more recently, plastics bottles. They traditionally consist of a top panel lined with a sealing compound, and a peripheral skirt which is crimped onto the bottle to close it. The closure is removed with a traditional bottle opener, or in some cases can be twisted off of a threaded finish on the bottle.
  • the present invention seeks to provide an improved method for the capping of bottles, and an improved closure for use therein.
  • the above method results in a bottle closed with a crown closure which creates a distinctive appearance. Furthermore, the curl portion serves to maintain the cut edge of the metallic closure away from the surface of the bottle. Thus, even if rust starts to form on the edge of the closure, e.g in hot and humid climates such as the Far East, this rust is not deposited on to the bottle surface when the closure is removed.
  • the crown closure is preferably provided with an outwardly facing curl portion, and preferably also comprising more than 360° of material when viewed in cross section.
  • the reforming step acts to roll the curl portion downwardly with respect to the centre panel.
  • the curl portion is partially unrolled during the reforming operation as it is moved under the capping bead.
  • the reforming step acts to roll the curl portion such that there is still more than 270°, and preferably 360° of material when viewed in cross section, after the curl portion has been moved under the capping bead.
  • the reforming step also acts to tighten the curl portion as it is moved.
  • the reforming step moves the entire curl portion under the capping bead.
  • the method preferably includes a reforming step comprising contacting the curl portion with an annular tool having a tapered infeed portion, and moving the annular tool downwardly to move the curl portion under the capping bead on the bottle.
  • the tool has a generally conical shape, at least in respect of its curl contacting surface.
  • the reforming step comprises contacting the curl portion with a tool having a plurality of projections thereon, and moving the projections with respect to the curl portion so as to form a fluted arrangement in which a plurality of sections of the curl portion are moved under the capping bead of the bottle.
  • This arrangement is particularly suited for the capping of crown closures having significantly more than 360° of material in their curl portion.
  • the invention further resides in a metallic crown closure including a centre panel, and a peripheral skirt portion depending downwardly therefrom, the distal end of the skirt portion being curled outwardly to form a curl portion, the curl portion comprising more than 360° of material when viewed in cross section.
  • the metallic crown closure is conveniently formed of aluminium, steel, or of metal coated with a polymer material.
  • the invention provides a crown closure with a distinctive appearance, and significant functional advantages.
  • the curled skirt has several advantages over the conventional corrugated skirt, not least in that it provides less of a safety hazard if discarded inappropriately.
  • the uncurled corrugated crown closures are prone to a problem known as 'dusting', in which closures contact each other during transit and the sharp edges of the crown closures chip off small particles of coating materials, producing dust particles which can cause contamination.
  • the curled periphery of the crown closures of the present invention help to avoid this problem.
  • the use of a curled portion which on application is moved under the capping bead may allow the use of thinner material.
  • the curl adds strength to the closure, giving an opportunity for lightweighting.
  • Another possible advantage is that, by providing a relatively plain skirt portion as opposed to the corrugated skirts used previously, the skirt portion may be used for printing decorative or promotional material.
  • capping apparatus shown generally at 1 comprises a capping tool 2 reciprocal on a central shaft 3.
  • the capping tool is generally cup shaped and comprises a cylindrical sidewall 4 depending from an upper end 5.
  • a central hole 6 allows the shaft 3 to pass therethrough.
  • the lower end of the tool is open, the opening 7 being provided with a tapered infeed section 8.
  • the shaft 3 has a piston plate 9 at the lower end thereof and a spring 10 is constrained between the piston plate and the upper end 5 of the tool.
  • a bottle shown generally at 11 is presented to the apparatus 1, with a crown closure 12 placed thereon.
  • the crown closure comprises a centre panel 13 and a peripheral skirt 14 depending therefrom.
  • the skirt 14 terminates in an outer curl 15 which, as shown in Fig.3, comprises a complete curl including at least 360° of material.
  • a gasket of sealing compound 16, typically a plastisol material, is attached to the underside of the centre panel between the panel and an annular top surface 17 of the bottle.
  • the bottle also includes an annular capping bead 18, and the outer curl 15 lies adjacent the capping bead 18.
  • the piston plate 9 holds the closure in position, and the capping tool 2 is lowered on the central shaft from the position shown in Figs.1 and 3 to that shown in Figs. 2 and 4.
  • the capping tool 2 is lowered, the tapered infeed section 8 progressively contacts the outer curl 15, moving it downwardly and inwardly to the position shown in Fig.4, in which it lies under the capping bead 18.
  • the outer curl 15 is partially uncurled, but remains curled to the extent that at least 270° of material is contained within the curl.
  • the crown closure 12 is attached to the bottle 11 having a distinctive slimline appearance.
  • the cut edge 19 of the closure is hidden so as not to pose a danger to users, and yet it is also maintained in a position away from the surface of the bottle so that if rust starts to form on the cut edge 19, it is not in contact with the bottle 11.
  • Figs.5 to 7 show an alternative embodiment of apparatus in which features similar to those in Figs. 1 to 4 are designated with like reference numerals.
  • the apparatus is suitable for capping crown closures 12 in which the outer curl 15 is provided with substantially more than one turn of material, in this case approximately 11 ⁇ 2 turns of metal.
  • the capping tool 2 differs from that described previously in that the tapered infeed section 8 is castellated, and has inwardly extending segments 20 separated by land portions 21. This tool is shown in Fig.6.
  • the operation of the apparatus is similar to that previously described, with the capping tool 2 being lowered on the central shaft 3 as shown in Fig.7.
  • the segments 20 contact the outer curl 15 so as to urge it under the capping bead 18 at those positions around its circumference in which contact is made.
  • the result is the petaloid structure of Fig.8, in which reformed areas 22 alternate with plain areas 23 around the circumference of the skirt 14.
  • the crown closure 12 may be removed from the bottle 11 using a conventional bottle opener.
  • the plain areas 23 provide particularly good sites on which the bottle opener can be employed.
  • Figs. 9 & 10 show an alternative crown closure having a centre panel 13, peripheral skirt 14 and sealing compound 16 etc. as previously described.
  • the skirt 14 is flared outwardly and the curl at the end thereof is an inwardly facing curl 24.
  • the closure 12 is placed on a bottle 11 as before, and presented to apparatus as previously described with reference to Figs. 1 to 4.
  • the capping tool moves downwardly reforming the skirt 14 into the position shown in Fig.10, in which the inner curl 24 is rolled under the capping bead 18 on the bottle 11, securing the crown closure on to the bottle as previously described.
