Definitions

  • the present invention relates to a closure for a container, particularly containers for supplying beverages to consumers.
  • the invention has particular utility to closures for containers for the storage and supply of carbonated and other sparkling drinks, but is also suitable for use with other types of drinks or other materials.
  • Closures that have a separate ring or collar carrying a screw thread for securing a cap to a container are known from United States Patent Nos. 3,603,472 and 4,576,296, International Patent Application WO 84/01763, and European Patent Application EP 0517676, for example.
  • the applicants have also proposed containers with cap-on-collar closures as described, for example, in WO 2006/000774 and WO2008/012539 the disclosure of which is incorporated herein.
  • the present invention seeks to provide improvements over closures such as those disclosed in WO 2006/000774 and WO2008/012539.
  • a closure for a container body having a circular opening with an axis though the centre thereof
  • the closure comprising a collar mountable on the container body and a cap for securing to the container body via the collar to close said opening, the collar being movable between a contracted configuration and an expanded configuration such that at least parts thereof are radially moveable between inner and outer positions, the collar having one or more first thread features and the cap having one or more second thread features such that, upon rotation of the cap relative to the collar, engagement between the first and second thread features causes axial and/or radial movement between the cap and the collar, wherein the cap is formed of metal, or other malleable material, with a top portion and ' a skirt portion depending therefrom, parts of the skirt portion being deformed inwardly to form at least parts of said second thread features.
  • the present invention builds on that described in WO2008/012539 and, in particular, provides an implementation in which the cap, and preferably both the cap and collar, are formed from metal.
  • a metal enclosure has the advantage that metal has high inherent barrier properties (e.g. to the passage of gasses, such as oxygen and carbon dioxide, therethrough) and a lower tendency to fail over time, e.g. due to material creep or catastrophic rupture.
  • the cap and collar are preferably formed from pressed metal sheet.
  • the cap and/or the collar may also be formed in a similar manner from some other malleable material, eg a suitable plastic material, that can be deformed in a similar manner, eg in a pressing operation (as distinct from being formed by an injection moulding and/or blow moulding process).
  • some other malleable material eg a suitable plastic material
  • the invention thus provides novel forms of thread features for a cap-on-collar closure of the type defined above which are capable of being formed in a pressing operation.
  • a closure for a container body having a circular opening with an axis though the centre thereof
  • the closure comprising a collar mountable on the container body and a cap for securing to the container body via the collar to close said opening, the collar being movable between a contracted configuration and an expanded configuration such that at least parts thereof are radially moveable between inner and outer positions, the collar having one or more first thread features in the form of outwardly projecting protrusions spaced around the outer surface of the collar and the cap having one or more second thread features such that, upon rotation of the cap relative to the collar, at least in a loosening direction, engagement between the first and second thread features causes axial and/or radial movement between the cap and the collar, a plurality of apertures being provided in a skirt portion of the cap through which said first thread features project when the collar is in the expanded configuration such that all of said protrusions have to be simultaneously pressed radially inwards through said apertures before the cap can be rotated
  • This aspect of the invention enables a capping head to be used to simultaneously press said protrusions inwards when the closure is fitted to a container and prior to the cap being rotated in the tightening direction.
  • This feature also provides a form of tamper evidence as, once the cap has been rotated in the loosening direction so that said projections re-emerge through the apertures in the skirt of the cap (which provides a visual indication that the cap has been undone), it is very difficult, without the use of a special tool, to simultaneously press all the projections inwards so the closure cannot be re-tightened.
  • references to directions such as horizontal and vertical used herein are to be interpreted in relation to a closure relative to a container on which it is mounted when the container is standing with its axis upright.
  • An advantage of a cap-on-collar closure is that by providing a collar on a container body, to which a cap may be secured in order to close the container, which collar preferably may be removed from the container body, the container body can be made free from exterior threads or other securement means for securing the cap thereto.
  • Providing a beverage container that is substantially free from exterior threads or other securement means enables the provision of a truly practical beverage container from which consumers may drink directly. This is because the presence of threads adjacent to the opening is a major reason for bottles and known wide-mouth containers being impractical as truly acceptable drinking vessels for consumers.
  • the collar comprises a plurality of radially movable features arranged spaced-apart from each other along the circumferential extent thereof, and the cap and the collar include cooperating thread features by which the cap may be secured to the collar.
  • the radially movable features of the collar are connected to each other by means of a ring portion of the collar to which the said features are directly connected.
  • the radially movable features of the collar preferably include radially-inwardly projecting shoulders which preferably engage with the lip or other retaining part of the container body to retain the collar thereon.
  • thread features comprising a plurality of circumferentially spaced apart components reduces the torque required to release the cap. This is of particular importance with a wide mouth container otherwise the torque required to unscrew the closure may be difficult for a user to apply by hand.
  • the opening of the container body is preferably a wide-mouth opening.
  • a wide-mouth opening is meant (at least in its broadest sense) an opening of a size suitable for a person to drink from the container in the same manner as from a drinks glass or similar drinking vessel. That is, in its broadest sense, the wide-mouth opening of the container (for embodiments of the invention having a wide-mouth opening) generally renders the container suitable as a drinking vessel from which a beverage supplied in the container may be conveniently drunk (in contrast to conventional narrow-necked bottles and ring-pull cans which generally are not regarded as comfortable drinking vessels).
  • the diameter of the wide-mouth opening of the container will normally need to be at least 40mm, preferably at least 45mm, and more preferably at least 50mm. Additionally, an excessively wide opening is generally difficult for the consumer to drink from, and thus the wide-mouth opening preferably has a diameter no greater than 150mm, more preferably no greater than 100mm, and especially no greater than 80mm. A particularly preferred diameter range for the wide-mouth opening is 50 to 80mm, and examples of particular preferred diameters include 53mm and 63mm.
  • the opening of the container body may be a narrow- mouth opening, e.g. a bottle-type opening.
  • a narrow- mouth opening e.g. a bottle-type opening.
  • Such an opening may have a diameter of less than 40mm, for example.
  • Conventional standard bottle mouth sizes include diameters of 28mm and 38mm, and the opening of the container body of some embodiments of the present invention may have such a diameter.
  • the container body preferably has no thread or thread segments on its exterior. Consequently, the container body preferably is comfortable for a consumer to drink directly from the container body.
  • a wide variety of thread forms for securing the cap to the container body via the collar is possible.
  • at least some embodiments of the invention are intended for the storage and supply of carbonated and other sparkling drinks, for example beers, ciders, sparkling wines (including champagne), other fizzy alcoholic beverages, and non-alcoholic fizzy and sparkling beverages, including sparkling water and carbonated soft drinks.
  • the engagement between the cap and the collar to include provision for gas venting upon partial removal of the cap from the container body, to prevent so-called "missiling" of the cap whereby the cap is violently ejected from the container body as the container is opened, by the gas pressure of the contents of the container.
  • the collar and the cap may include means, preferably engageable elements, to block or restrict removal of the cap from the collar beyond an intermediate position (between fully secured and fully released) when the cap is under an axial pressure in a direction emerging from the container body.
  • the cap, the collar and the container body are constructed and arranged to provide a vent for venting gas from the container body at least when the cap is in an intermediate position (between fully secured and fully released).
  • the act of removal of the cap from the container body causes the collar to be removed from the container body together with the cap. That is, the collar may be removed from the container body together with the cap.
  • the cap and/or the collar may include tamper-evident means.
  • the tamper-evident means is ruptured or removed from the cap or the collar (respectively) by the act of removal of the cap from the container body.
  • the tamper-evident means and/or the collar may include means to prevent the cap from accidentally unscrewing from the collar under the influence of pressurization within the container (e.g. due to a pressurized beverage held in the container).
  • Embodiments of the invention preferably include sealing means to seal the container.
  • sealing means may comprise part of the cap and/or the container body and/or the collar and/or a separate component, for example.
  • Preferred sealing means include sealing flanges and/or other sealing members, for example gaskets and the like.
  • Another possible sealing member is a membrane seal, for example comprising a metal foil seal (e.g. formed from aluminium foil), which may optionally be provided with one or more polymer layers on one or both major surfaces thereof.
  • the foil seal may provide an excellent gas barrier, for example.
  • the use of a metal foil seal may enable the formation of a seal by induction heating, e.g. by bonding one or more polymer layers to the container body and/or to the cap.
  • the foil seal or other membrane seal may be provided on the cap and/or the container body and/or the collar and/or separately.
  • the container body may be formed from metal, glass or polymer material, e.g. a polyolefin such as polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • the closure is preferably formed entirely of metal although the collar may be formed from a polymer material, e.g. polyethylene terephthalate (PET).

  • Figure 2 is an enlarged perspective view of the cap and collar of Figure 1 when assembled together;
  • Figures 3A and 3B are schematic sectional views of the part of the closure shown in Figure 2 in an initial position and after being rotated in a tightening direction; DESCRIPTION OF PREFERRED EMBODIMENTS

  • Figure 1 shows a container comprising a container body 1 and a closure which comprises a cap 2 and a collar 3.
  • the container body 1 has a circular opening IA with an axis Al passing therethrough and an outwardly extending -lip IB (also shown in Figures 3A and 3B).
  • the container body 1 is formed of metal, e.g. aluminium, and the lip IB comprises a rolled edge.
  • the container body 1 may be formed of other materials, e.g. plastic or glass.
  • the cap 2 is formed of metal, e.g. aluminium, and is preferably formed from pressed metal sheet.
  • the cap comprises a top portion 2A for covering the opening IA of the container body 1 and a skirt portion 2B depending from the periphery of the top portion 2A.
  • the free edge 2C (the lower edge) of the skirt portion 2B is rolled or deformed inwards to form a thread feature on the cap 2.
  • portions of the lower edge of the skirt portion 2B are rolled inwards at an angle (typically of a few degrees) to the horizontal to form a plurality of thread sections (typically around eight) around the circumference of the skirt portion 2B.
  • a plurality (again eight) of apertures 2D are provided in the skirt portion IB around the circumference thereof.
  • the collar 3 is also preferably made of metal (again preferably pressed from metal sheet), although in other embodiments may be made of other material, e.g. plastic.
  • the collar 3 is divided into eight portions by hinge points 3A and each portion has an outwardly projecting thread feature 3B.
  • the hinge points 3A preferably comprise lines of reduced thickness (as shown in Figure 5A) which can be formed in a pressing operation and the thread features 3B are preferably formed as hollow pressings from the collar 3.
  • the cap 2 and collar 3 may be assembled together prior to being secured to a container body.
  • Figure 2 shows a cap and collar assembled together with the thread features 3B of the collar 3 located in the apertures 2D of the cap 2.
  • the manner in which the closure is secured to the container body 1 is similar to that described in WO2008/012539 referred to above.
  • the main difference is that at least the cap 2 (and preferably the collar 3) are formed of metal and the free edge of the skirt portion 2B of the cap is deformed inwardly to form a thread feature.
  • the collar 3 is sized (when in an expanded configuration) to fit over the lip IB of the container body and (when in a contracted configuration) is trapped beneath the lip IB.
  • Thread features of the cap 2 and collar 3 interact so that as the cap 2 is rotated in the tightening direction (clockwise when seen from above in the illustrated embodiment) relative to the collar 3, the collar is urged radially inwards towards, or held, in its contracted configuration and the cap is drawn down axially so as to engage (and preferably seal) the upper surface of the lip IA.
  • the cap 2 When the cap 2 is rotated in the loosening direction relative to the collar 3, the cap moves axially away from the container opening IA (which may allow venting) and the portions of the collar are allowed to move radially outwards to the . expanded configuration (in which the thread features 3B of the collar extend through the apertures 2D in the cap 2) whereby the collar 3 can be disengaged from the lip IB and the closure removed from the container body 1.
  • the thread features 3B of the collar thus correspond to thread features 7A of the collar 7 disclosed in WO2008/012539 and the apertures 2D in the cap 2 correspond to the deep recesses or pockets 5D in the cap 5 disclosed in WO2008/012539.
  • the thread features 3B and/or the apertures 2D may be designed so that it is difficult to rotate the cap 2 in the tightening direction without also simultaneously pressing in all eight of the thread features 3B inwards. This provides a form of tamper evidence as, once a cap has been loosened so the thread features 3B engage in the apertures 2D, it is difficult to re-tighten without access to a capping tool (or other appropriately shaped tool) to simultaneously press all the thread features inwards.
  • Figures 5A and 5B show perspective views of the collar 3 in its expanded and contracted configurations, respectively. As shown, portions of the collar 3 flex inwardly between the hinge points 3A so that parts of the collar between the hinge points 1 move inwards radially (so they can engage beneath the lip IB of the container body 1).
  • Figures 6A and 6B are schematic plan views of the collar 3 in its expanded and contracted configurations. Preferably, the resilience of the collar 3 urges it towards the expanded configuration unless the thread features 3B are held in the radially inner position by the skirt portion 2B of the cap.
  • collar may be used, e.g. such as those described in WO2008/012539, in particular a collar with a break in it which enables it to move between an expanded and a contracted configuration.
  • Figure 7A shows a perspective view of the cap 3 from above and Figure 7B shows a perspective view of the cap 3 from beneath.
  • Figure 8 is an internal, developed side view of the skirt portion 3B of the cap, i.e. as if the annular flange portion was laid out as a linear strip.
  • the lower edge 2C of the skirt portion 2B is deformed inwards, e.g. by being curled or rolled inwards.
  • the curled edge presents a first, downwardly facing surface 2E, a second inwardly facing surface 2F and a third, upwardly facing surface 2G (these also being illustrated in Figures 3 and 4).
  • it is the upper surface 2G of the curled edge which provides the thread feature of the cap which engages the undersides 3E of the thread portions 2B of the collar 3.
  • the curled edge 3C is thus shaped so that portions of the upper surface 2G are inclined between each of the apertures 2D (as shown in Figure 8).
  • the curled edge 2C may be shaped so that the inwardly facing surface 2F is not circular but is shaped to provide a plurality of thread features for engaging an outwardly facing portion of the collar 3.
  • the downwardly facing surface 2E of the curled edge comprises a plurality of inclined portions (rather than being horizontal around the circumference of the cap 2).
  • This surface does not provide a thread feature but is shaped in this manner as a consequence of the manner in which the free edge 3C of the skirt portion is deformed so as to provide a plurality of inclined regions on the upper surface 2G of the curled edge.
  • Figures 9A and 9B show horizontal sections through the closure in the positions shown in Figures 3A and 3B.
  • Figure 9A shows a thread feature 3B of the collar protruding through an aperture 2D in the cap 2 when the collar 3 is in its expanded configuration prior to the closure being tightened.
  • Figure 9B shows the thread features 3B when held in an inner position (corresponding to that shown in Figures 5B and 6B) by an inner surface of the skirt portion 2B of the cap 2. It also shows a hinge point 3A of the collar 3 being visible through an aperture 2D in the cap 2. The emergence of the hinge points 3A into the apertures 2D may also provide an anti-back off feature, i.e. an additional resistance that needs to be overcome before the cap can start rotating in the loosening direction. This helps reduce the risk that the closure might be loosened e.g. due to an elevated pressure within the container.
  • Figure 1OA illustrates a modified form of the cap 2.
  • a hollow embossed protrusion 2H is provided for accommodating a thread feature 3B of the collar instead of an aperture 2D.
  • These protrusions 2H also provide finger grips to assist a user in grasping the cap 2 for rotation.
  • a capping tool cannot be used to push the thread features inwards in the manner shown in Figures 4A and 4B.
  • Figure 1OB illustrates a further modified form of the cap 2 similar to that shown in Figure 1OA but with a cut-out 21 provided in each of the embossed protrusions 2H.
  • the cut-outs 21 enable a capping tool to engage the protrusions 3D in the manner described in relation to Figures 4A and 4B.
  • Figure 11 shows a modified form of the cap 2 which is provided with a pivotable member in the form of a plug 5 adjacent at least one of the apertures 2D in the skirt portion 2B.
  • Figures 12A-12C illustrate a further form of tamper evident feature.
  • at least one aperture 3F is provided in the collar 3 such that it is aligned with one of the apertures 2D in the cap 2 when the cap 2 is in the tightened position.
  • a separate plug 6 (or other member) can then be inserted through the apertures 2D and 3F as shown on Figure 12C to releasably secure the closure in a tightened configuration.
