Definitions

  • the present invention relates to containers, and particularly relates to containers for supplying beverages to consumers.
  • the invention has particular utility 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.
  • the invention also relates to container bodies, a cap and the combination of a cap and collar for providing such containers.
  • Containers that have a separate ring or collar carrying a screw thread for securing a cap to the container, are known from U.S. Pat. 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 the disclosure of which is incorporated herein.
  • the present invention seeks to provide improvements over containers such as those disclosed in WO 2006/000774.
  • a container comprising a container body including a circular opening which defines an axis, a cap to close the opening and a collar, the cap comprising an annular skirt portion having a plurality of spaced apart projections around its inner circumference and the collar comprising a ring with a plurality of spaced apart flaps, or other radially moveable parts, provided thereon, the collar being arranged to fit between the container body and cap with their axes aligned such that said projections respectively engage axially facing surfaces of the ring and the flaps or other radially moveable parts engage an axially facing surface of a lip (or other features) of the container body whereby the cap can be secured to the container body.
  • a container comprising a container body including an opening, a cap to close the opening and a collar arranged to fit between the container body and the cap, the collar having a plurality of spaced apart flaps or other radially moveable parts provided thereon and the cap having a first set of cam surfaces for urging the flaps or other radially moveable parts radially inwards to engage the container body and a second set of cam surfaces for urging the flaps or other radially moveable parts radially outwards to disengage from the container body upon rotation of the cap relative to the collar.
  • the cams of the first and second sets of cam surfaces are arranged alternately around an inner surface of the cap and rotation of the cap relative to the collar moves the flaps or other radially moveable parts from engagement with the first set of cam surfaces into engagement with the second set of cam surfaces.
  • Each flap or other radially moveable parts thus follows a chicane pathway during this rotation.
  • a container comprising a container body including an opening, a cap to close the opening and a collar, the collar being arranged to fit between the container body and the cap so as to secure the cap to the container body, the collar having one or more inwardly directed projections for engaging one or more features of an external surface of the container body whereby rotation of the collar relative to the container body is limited, said one or more projections being provided on a resilient arm extending from said collar so as to be radially moveable into and out of engagement with said one or more features of the external surface of the container body.
  • said one or more projections are provided at the distal ends of resilient arms which extend part way around the inner circumference of the collar or which extend in a substantially axial direction from the collar.
  • a container comprising a container body including an opening, a cap to close the opening and a collar arranged to fit between the container body and the cap, the cap being rotatable relative to the collar between a first position in which the cap is secured to the container body via the collar and a second position in which the cap is removable from the container body, the cap being secured to the collar by a threaded engagement therebetween, said threaded engagement being 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).
  • a container comprising a container body including an opening, a cap to close the opening and a collar arranged to fit between the container body and the cap, the cap being rotatable relative to the collar between a first position in which the cap is secured to the container body via the collar and a second position in which the cap is removable from the container body, the cap having skirt portion with a plurality of spaced apart apertures therein through which parts of the collar are visible so as to provide a visual indication as to whether the cap is in the first or second position relative to the collar.
  • a container body for use in providing a container as described above, the container body having a smooth lip extending around the opening thereof and one or more isolated retaining features in an external surface thereof.
  • the retaining features may be isolated recesses in an external wall of the container (spaced from a lip of the container), or a recess in the container lip or a stop feature provided on the underside of the container lip.
  • the external surface of the container body towards the open end thereof is substantially parallel-sided or flares outwards such that the container body can be manufactured by an injection moulding process.
  • the container body is shaped so as to be nestable within another container body of the same shape.
  • a cap and a collar for use in providing a container as described above.
  • the collar may be pre-assembled within the cap.
  • the cap and collar may be arranged so as to be manufactured as a single component and then separated either before or after the collar has been assembled within the cap.
  • the cap and collar may be joined by interconnecting parts which are ruptured as the cap is rotated relative to the collar.
  • a cap for use in providing a container as described above.
  • the cap has a skirt portion with a plurality of spaced apart apertures therein and a plurality of spaced apart projections around its inner circumference, respective apertures and projections being aligned with each other whereby the apertures facilitate manufacture of the cap by an injection moulding process using a straight up and away injection moulding tool.
  • An advantage of the invention 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, enables the container body to be free from exterior threads or other securement means for securing the cap thereto.
  • Providing a beverage container that is 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.
  • De-coupling the method of securing the cap to the container body i.e. via the collar
  • any method of sealing the container e.g. via a seal provided between the cap and the container body.
  • This is to be contrasted from known containers in which an inner cap-like part both provides a seal against the container body and contributes to the securing of an outer cap to the container body, for example.
  • Such de-coupling can often provide both better sealing and better securement.
  • the container body of the invention includes one or more retaining parts by which the collar is retained on the container body until removal of the cap causes the collar to be removed or removable from the container body.
  • the retaining part may be a rim or lip of the container body, preferably a radially-outwardly projecting lip.
  • the collar is retained on the container body by being trapped beneath the lip or other retaining part of the container body.
  • the (or each) retaining part could be a recess (e.g. a depression or indentation) in a surface, preferably an exterior surface, of the container body.
  • the container body may be provided with one or more recesses provided around the exterior circumference of the container body.
  • the collar can engage with and/or can be secured to the container body independently of the cap. That is, preferably the collar does not require the action or the presence of the cap in order for the collar to be engaged with and/or secured to the container body.
  • the collar comprises a plurality of flaps or other radially moveable parts arranged spaced-apart from each other along the circumferential extent thereof, the cap and the collar including cooperating securement means by which the cap may be secured to the collar.
  • the flaps or other parts of the collar are indirectly connected to each other by means of a ring portion of the collar to which the flaps or other parts are directly connected.
  • the ring portion of the collar is the lowermost portion thereof, with the flaps or other parts extending substantially vertically therefrom.
  • the flaps or other radially moveable parts of the collar preferably include radially-inwardly projecting shoulders which preferably engage with an axially facing surface of the lip or other retaining part of the container body to retain the collar thereon.
  • the cap is releasably securable to the container body via the collar, preferably by means of a threaded engagement with the collar. Consequently, the (or each) securement means of the collar and/or the cap preferably is a thread.
  • the threaded engagement may comprise a screw-threaded engagement. Preferably, however, the threaded engagement is a bayonet-style engagement.
  • the term “thread” as used herein includes (at least in the broadest aspects of the invention) continuous and discontinuous threads, (e.g. continuous and discontinuous screw threads), and bayonet-style threads, for example.
  • Threads used in relation to the invention may, for example, comprise a plurality of segments (each thread segment comprising a said securement means), in which case the thread may be discontinuous (e.g. a discontinuous screw-thread or a bayonet-thread), or it may be substantially continuous because the effect is that of a substantially continuous screw-thread pattern.
  • the thread may be discontinuous (e.g. a discontinuous screw-thread or a bayonet-thread), or it may be substantially continuous because the effect is that of a substantially continuous screw-thread pattern.
  • 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 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 40 mm, preferably at least 45 mm, and more preferably at least 50 mm.
  • 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 150 mm, more preferably no greater than 100 mm, and especially no greater than 80 mm.
  • a particularly preferred diameter range for the wide-mouth opening is 50 to 80 mm, and examples of particular preferred diameters include 53 mm and 63 mm.
  • 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 40 mm, for example.
  • Conventional standard bottle mouth sizes include diameters of 28 mm and 38 mm, 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 removal of the cap from the container body may cause the removal of the collar from the container body. Additionally or alternatively, the act of removal of the cap from the container body may cause 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, for example as described above.
  • the cap and/or the collar may include tamper-evident means (e.g. a tamper-evident band).
  • tamper-evident means e.g. a tamper-evident band
  • 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 and its components may be made from any suitable material, including metal and/or glass and/or polymer material.
  • Polymer materials are generally preferred for the cap and the collar, especially polyolefins, e.g. polyethylene or polypropylene.
  • the container body preferably is formed from glass or polymer material, especially a polyolefin, e.g. polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • the polymeric components preferably are formed by moulding, especially injection moulding and/or blow moulding.
  • references to directions such as upwards, downwards, vertically, etc. used herein should be understood as referring to directions relative to a container when standing upright on a horizontal surface.

  • the upper surface of the thread feature 5 F has an inclined (at about 10 degrees) lead-in surface 53 following by a substantially horizontal surface 5 K and these engage with an inclined (again, at about 10 degrees) surface 6 B provided on the underside of the collar 6 which also leads onto a substantially horizontal surface 6 C.
  • the collar 6 is preferably first fitted into the cap 5 . Once fitted therein, the collar 6 is recessed within the cap 5 and does not project beyond the end of the skirt portion 5 B (unlike the arrangements described in WO 2006/000774). This improves the appearance of the closure and the user need not handle the collar 6 when operating the closure.
  • the sealing member 8 (if used) may be assembled in the cap 5 either before or after assembly of the collar 6 with the cap 5 .
  • the collar 6 is initially assembled with the cap 5 with the flaps 7 lying in spaces between the apertures 5 E of the cap 5 .
  • the collar 6 can be easily mounted within the cap 5 in this position by axially inserting the collar 6 into the cap 5 so the flaps 7 pass between the thread features 5 F until the lower surface 6 A of the collar 6 engages the upper surfaces of the thread features 5 F.
  • the inward facing surfaces of the thread features 5 F are chamfered to assist the collar 6 in riding over these features until the collar 6 snaps into place behind the thread features 5 F.
  • the inner surfaces 7 B of the flaps engage the second cam features 5 H such that the flaps 7 are urged to a radially outward position whereby the cap 5 with collar 6 assembled therein can be installed axially onto container 1 ; the flaps 7 being held at a diameter similar to or preferably slightly greater than the maximum diameter of the lip 3 .
  • the cap 5 and collar 6 are then rotated on the container (in either direction) until the projections 9 engage in the respective recesses 2 A. Engagement of the projection 9 in the recesses 2 A effectively prevents or restricts further rotation of the collar 6 relative to the container 1 (the projection 9 and recesses 2 A each being provided with substantially flat vertical sides which engage each other to prevent such rotation).
  • the cap 5 If the cap 5 is then rotated in the tightening direction (clockwise when viewed from above), the cap 5 rotates relative to the collar 6 and the container 1 . During this rotation, the thread features 5 F of the cap 5 slide over the underside of the collar 6 so that the cap 5 is axially tightened down onto the lip 3 of the container so as to seal the opening 4 of container. At the same time, rotation of the cap 5 relative to the collar 6 moves the flaps 7 out of engagement with the second cams 5 H and into engagement with the first cam features 5 G which causes the flaps 7 to be urged to a radially inward position in which the shoulders 7 C of the flaps are engaged with the underside 3 B of the lip 3 . By this means, the collar 6 , and hence the cap 5 , is securely held on the container 1 .
  • FIGS. 9A and 9B show the closure in this position with the collar 6 fitted between the cap 5 and the container 1 with the axes of the cap, collar and container aligned with each other.
  • the shoulders 7 C are engaged under the lip 3 and are held in this position by the first set of cams 5 G.
  • the upper surface of the thread features 5 F are in the tightened position with the lower axially facing surface 6 A of the collar 6 whereby the circular portion 5 A of the cap is drawn down into sealing engagement with the lip 3 (via sealing member 8 ).
  • the cap 5 is rotated in the loosening direction (anti-clockwise when viewed from above) relative to the collar 6 and the container 1 whereby the flaps 7 move out of engagement with the first set of cams 5 G and into engagement with the second set of cams 5 H whereby the flaps 7 are urged radially outwards.
  • the cap 5 and collar 6 are free to be lifted axially away from the container 1 .
  • the collar 6 is rotated relative to the thread features 5 F so that the cap 5 is no longer urged downwards into tight engagement with the lip 3 .
  • the cap 3 is thus free to lift slightly, eg due to elevated pressure within the container, in order to vent the container. This is preferably arranged to occur before the flaps 7 are fully disengaged from the lip 3 to reduce the risk of the cap 5 missiling away from the container 1 .
  • other venting means may be provided to reduce this risk. Venting the internal pressure also helps reduce the torque required to unscrew the cap 5 .
  • a weak point in the skirt portion 5 B is ruptured so as to provide tamper evidence. This may be caused by providing interengaging parts on the external surface of the collar 6 and internal surface of the skirt portion 5 B of the cap (or small spot-welds therebetween) which engagements have to be overcome to unscrew the cap 5 giving rise to rupture of the skirt portion 5 B (or some other tamper evident feature).
  • the upper surfaces of the recesses 2 A are preferably angled so the projections 9 can disengage therefrom relatively easily as the cap 5 and collar 6 are lifted off the container 1 .
  • the upper and lower surfaces of the projection 9 are also chamfered to assist their movement into and out of the recesses 2 A in a vertical direction when the closure is placed on and removed from the container 1 .
  • FIG. 10B shows the closure in a position ready to be removed from the container 1 .
  • the flaps 7 are held in a radially outward position by the second cams 5 H so the shoulders 7 C of the flaps 7 are disengaged from the underside of the lip 3 .
  • the figure also shows the cap having lifted slightly relative to the collar 6 and container 1 so the sealing member 8 is no longer held in sealing engagement with the lip 3 .
  • the first and second cam features 5 G and 5 H effectively form a chicane pathway through which the flap 7 passes as the cap 5 is rotated on the collar 6 (as best shown in FIG. 6 ).
  • the flap 7 is initially urged outwards by cam 5 H then, as the cap is rotated, the flap 7 disengages the cam 5 G and the opposite side of the flap 7 is engaged by the first cam 5 G which urges it inwards.
  • the resilience of the flaps 7 may be relied upon to move them in at least one direction (i.e. either inwards or outwards). However, this does not provide the same positive movement provided by the chicane camming arrangement and if the flaps 7 are held in one position for an extended time they may lose their resilience and so may not operate reliably.
  • the flaps 7 may be formed with a resilient connection, e.g. a living hinge, with the ring so that they can flex inwards and outwards with a reduced tendency to twist the ring.
  • a resilient connection e.g. a living hinge
  • the first cams 5 G comprise relatively long ramps at each end (although only one end is involved in the camming action) separated by a relatively long plateau area whereas the second cams 5 H comprise curved surfaces at each end separated by a relatively short plateau area.
  • the closure can be re-fitted to the container 1 by axially pressing it onto the lip 3 , rotating to engage the projections 9 with the location recesses 2 A then rotating the cap 5 to seal it onto the lip 3 .
  • the flaps 7 are located in alignment with the apertures 5 E whereas when the cap 5 has been loosened ready for removal, the flaps 7 no longer occlude the apertures. This provides a visual indication as to whether the cap 5 is in a sealed or ready to remove position. If desired, the flaps 7 may be coloured to enhance this visual indication.
  • FIG. 11 illustrates how the cap 5 and collar 6 may be manufactured as a single component, e.g. by injection moulding, and then assembled together.
  • FIG. 11A shows a plan view of the cap 5 and collar 6 as manufactured, side by side with interconnecting parts 11 .
  • FIG. 11B shows the interconnecting parts 11 in more detail.
  • the cap 5 and collar 6 can be hinged about the interconnecting parts 11 such that they pass through slots 11 A formed in the skirt portion 5 B of cap 5 .
  • FIGS. 11C-11E illustrate how the collar 6 is hinged about the interconnecting parts so as to assemble the collar 6 into the cap 5 to a position corresponding to that shown in FIG. 10 ready for placing the closure onto the container 1 .
  • the interconnecting parts 11 are severed so the cap 5 can rotate relative to the collar 6 .
  • One way of doing this is to make the interconnecting parts 11 sufficiently thin so that as the cap is rotated, the skirt portion 5 B thereof ruptures the interconnecting parts 11 at the point where they pass through the slots 11 A in the skirt portion 5 B.
  • the illustrated container has, as mentioned above, a number of advantages over the containers described in WO2006/00774.
  • the illustrated container is designed to be much easier to manufacture. It has a simpler form and, in some case, requires 30% less material so substantially reducing the cost of manufacture.
  • FIGS. 12A and 12C illustrate a second embodiment of a container according to the present invention.
  • the container again comprises a container body 21 with an external wall 22 and a closure comprising a cap 25 and a collar (not shown in FIG. 12 ) by means of which the cap is secured to the container body 21 .
  • the cap 25 and collar are similar to those described above with reference to FIGS. 5-8 but in this case the cap 25 is not provided with apertures corresponding to the apertures 5 E shown in FIGS. 4 and 5 .
  • FIGS. 12A and 12B show perspective views from above and beneath of the cap 25 .
  • the cap 25 is provided with a plurality of spaced apart thread features 25 F, a plurality of first circumferentially spaced apart cam features 25 G and a plurality of second circumferentially spaced apart cam features 25 H similar to the corresponding parts of the cap described in relation to FIGS. 4 and 5 .
  • the cam features 25 G have a series of grooves formed therein to reduce the amount of plastic used in the cap, and hence reduce its weight, but function in a similar manner to those described in relation to FIGS. 4 and 5 .
  • cap 25 is not provided with apertures to enable the thread features 25 F to be formed using a straight up and away injection moulding tool these features are instead formed using a collapsing core to create the undercuts of these parts.
  • FIGS. 13A-13C illustrate a modified form of the container body 31 .
  • the illustrated container body 31 has a lip 33 around its upper end which defines a wide mouth opening 34 .
  • two small stop members 31 A are provided on the underside of the lip 33 each having a tapered form 31 B at one end and a flat face 31 C at the other end (but arranged in opposite orientations).
  • a feature on the collar (not shown) is arranged to engage one of the stop members 31 A (depending on which direction the rotation occurs) so rotation of the collar relative to the container is limited when the cap is rotated to secure it to the container or to remove it from the container.
  • Said feature on the collar is able to ride over the tapered end of the stop member 31 A in one direction but is brought to a halt when it engages the flat face 31 C of one of the stop members.
  • stop members are thus an alternative to providing a recess 2 A in the container wall as described in the embodiment shown in FIGS. 1-3 .
  • FIGS. 14A-14D illustrate a modified form of collar 46 which may be used in one or more of the embodiments described herein.
  • the collar 46 has a plurality of circumferentially spaced apart flaps 47 extending upwardly from a ring part 46 A of the collar.
  • Each of the flaps 47 comprises an outer surface 47 A for engaging a first set of cam features of the cap (such as the cam features 25 G shown in FIG. 12B ), an upstanding tab 47 B the inner surface of which engages a second set of cam features of the cap (such as the cam features 25 H shown in FIG. 12B ) and a shoulder 47 C for engaging under the lip of a container (such as the lip 33 shown in FIG. 13 ).
  • the first and second sets of cam features 25 G and 25 H drive the flaps 47 radially inwards and radially outwards upon rotation of the cap 25 relative to the collar 46 so as to engage the shoulders of the flaps under the lip of the container 31 and disengage them therefrom.
  • the flaps 47 thus follow a chicane pathway as the cap 25 is rotated relative to the collar 26 .
  • the flaps 47 are recessed axially with respect to the ring part 46 A of the collar, ie. the lower end or root 47 D of the flap is connected to the ring part 46 A at a point beneath an upper sirface 46 B of the ring part 46 A.
  • This is best illustrated by a section through the collar 46 as shown in FIG. 14C and FIG. 15 .
  • One advantage of this is that the overall height of the collar 46 (in the axial direction) can be reduced.
  • thread features 48 are provided by axially facing surfaces projecting from (or formed by recesses in) the external circumferential surface of the ring part 46 A of the collar (whereas in FIG. 7 they are provided, at least partially, by axially facing surfaces on the underside of the collar 6 ).
  • the thread features 48 of the collar engage with thread features of the cap (such as the features 25 F shown in FIG. 12B ) to retain the collar 46 within the cap 25 and so that, upon relative rotation therebetween, the collar 46 is moved axially relative to the cap 25 . Further details of such thread features are described below with reference to FIGS. 16 and 17 .
  • the thread features 48 overlap in the axial direction with at least part of the flaps 47 .
  • the flaps 47 are still able to flex radially outwards (as best shown in FIG. 21A and described further below).
  • the collar 46 has nine flaps 47 at circumferentially spaced positions therearound. At least one, and preferably three, of these flaps has a separate, smaller, radially moveable flap (or arm) 49 adjacent thereto as shown in FIG. 14B .
  • Each radially moveable flap 49 has a projection 49 A which projects radially inwards for engaging with a retaining feature of a container body so as to limit the relative rotation between the collar 46 and the container body.
  • the projection(s) 49 A may, for example, be designed to engage one or more recesses in the container body (such as recess 2 A shown in FIG. 2 ) or one or more stop members provided on the underside of the lip of the container body (such as stop members 31 A shown in FIG. 13 ).
  • the projections 49 A preferably have a tapered form so that when the collar is rotated in one direction relative to the container body (e.g. the tightening direction), it is able to ride over the corresponding feature on the container body causing the flap 49 to flex radially outwards but when rotated in the opposite direction (e.g. the loosening direction) a face of the projection 49 A engages a face of the said feature (e.g. the face 31 C shown in FIG. 13B ) to limit further rotation of the collar 46 relative to the container body.

  • FIG. 15 is a partial, cross-sectional view of the cap 25 of FIGS. 12A and 12B , when mounted on the container body 31 of FIG. 13 by means of the collar 47 of FIG. 14 .
  • the Figure shows the shoulder 47 C of the collar 46 engaged beneath the lip 33 of the container 31 and shows a thread feature 25 F of the cap 25 engaged with a thread feature 48 of the collar 46 .
  • FIGS. 16A-16D show a further modified form of a cap 55 and collar 56 which are similar to the cap and collar shown in FIGS. 12 and 14 but in which the thread features 55 and 58 of the cap 55 and collar 56 have a specific form to assist in venting the container as the closure is loosened prior to removal from the container.
  • Each of the thread features 55 F of the cap 55 are provided with an additional small projection, or pip 55 G, projecting upwardly therefrom with a steep slope on one side therefrom and a shallow slope on the other side thereof.
  • Each of the thread features 58 of the collar 56 comprises a first, substantially horizontal surface 58 A, a second, inclined surface 58 B and a third substantially horizontal surface 58 C (similar to corresponding surfaces of the embodiments described above).
  • a cut-out, or scallop 58 D is, however, formed part way along the third surface 58 C for receiving the pip 55 G of the thread feature 55 F of the cap 55 .
  • Each of the thread features 58 of the collar 56 also has a steeply inclined surface 58 E, a more shallowly inclined surface 58 F and an end surface 58 G. These surfaces will be described further below.
  • cap 55 shown in FIG. 16A differs from that shown in FIG. 12B in that instead of a series of grooves being formed in the first cam features 35 G to reduce weight, a rectangular recess is formed in the first cam members 55 H (for the same reason).
  • FIGS. 17A and 17F schematically illustrate how the thread features of the cap 55 and collar 56 interact as the cap is first turned in the tightening direction ( FIGS. 17A to 17C ) and then as it is loosened ( FIGS. 17D to 17F ) for removal.
  • FIG. 17A shows the location of thread feature 55 F after the collar 56 has been axially located within the cap 55 .
  • thread feature 55 F moves from surface 58 A, along surface 58 B (whereupon the cap is drawn down onto the container mouth) and along surface 58 C ( FIG. 17B ) until the end of thread feature 55 reaches stop surface 58 G (as shown in FIG. 17C ).
  • pip 55 G passes scallop 58 D without difficulty due to the shallow slope of its leading edge.
  • the cap When the cap is rotated in the loosening direction (anti-clockwise when viewed from above), it moves from the position shown in FIG. 17C , along surface 58 C until the pip 55 G engages scallop 58 D (this position is typically reached following rotation of about five degrees) as shown in FIG. 17D .
  • the container contains a carbonated beverage (or is otherwise at an elevated pressure)
  • the pressure in the container raises the cap by a small distance, typically about 0.5 mm, as the pip 55 G enters the scallop 58 D. This enables the pressure in the container to reduce by venting though the small gap thus created between the cap and the container body.
  • the cap 55 After gassing-off has occurred, further rotation of the cap 55 in the loosening direction (which is now easier due to the reduced pressure within the container) moves the pip 55 G out of the scallop 58 D and further along surface 58 D ( FIG. 17E ) and then to the position shown in FIG. 17F (which is the same as that shown in Fire 17 A) from where the cap is ready for removal from the container.
  • the cap 55 is preferably pressed axially towards the container body until the pip is released from the scallop.
  • surfaces 58 E and 58 F are not critical. They are shown as corresponding to the upper surfaces of thread feature 55 F so as to engage therewith in the fully tightened position shown in FIG. 17C . However, this is not necessary and the thread feature can be prevented from being over-tightened simply by engagement with the stop surface 58 G.
  • FIGS. 18A and 18B show perspective views from above and beneath of a further modified form of collar 66 that may be used in preferred embodiments of the invention.
  • This is similar to the collar shown in FIG. 16C except that it has only eight (instead of nine) flaps 67 at spaced apart locations around its circumference.
  • This enables two smaller radially moveable flaps 69 (which provide a similar function to the smaller flaps 49 described in relation to FIG. 14 ) to be provided at diametrically opposite positions. It also further reduces the weight of the collar 66 .
  • the collar 66 only has eight thread features 68 rather than nine.
  • FIG. 18 shows a collar having two such smaller flaps 69 , it would also be possible to use just one such flap or, indeed, three or more such flaps. The preferred number is, however, two.
  • FIGS. 19A and 19B show perspective views from above and beneath of a cap 65 for use with the collar shown in FIGS. 18A and 18B .
  • Cap 65 is similar to that shown in FIG. 16 except that it only has eight thread features 65 F, eight first cam features 65 E and eight second cam features 65 H at spaced apart locations around its circumference (rather than nine). As will be described further below, this enables the second set of cam features 65 H to provide a second function, namely to drive parts of the collar 66 into secure engagement with the container (see description of FIG. 22B below).
  • the cap 65 and collar 66 of FIGS. 18 and 19 may be used with a container body of the types described above. Alternatively, they may be used with a further form of container 71 such as that shown in FIG. 20 .
  • This container comprises a stop feature in the form of a small recess or cut-out 71 A in a lip 73 around the mouth 74 of the container. Two such recesses 71 A may be provided, e.g. at diametrically opposite positions.
  • FIGS. 21A and 21B are cross-sectional views showing the cap 65 of FIG. 18 when mounted on the container 71 of FIG. 20 by means of the collar 66 of FIG. 19 showing flaps 67 in a radially outward position ( FIG. 21A ) and in a radially inward position ( FIG. 21B ).
  • FIGS. 22A and 22B are similar but show a smaller flap 69 in a first position in which it is free to move radially outwards ( FIG. 22A ) and in a second position in which it is held in a radially inward position ( FIG. 22B ).
  • FIG. 21A shows the position of the collar 66 when the closure has just been mounted on the container 71 (or when it is ready for removal therefrom).

Whilst the flap 69 is not driven to a radially outward position (like the flap 67 in FIG. 21A ) it is free to flex outwardly in this position so that as the closure is mounted on, or removed from, the container 71 , the flap 69 is able to flex past the lip 73 of the container.
