- closure 100 The construction and configuration of the closure 100 , and the method of its engagement on the container, has to be chosen with care to meet a number of desired criteria. It is, of course, required that the closure 100 is able to withstand the pressure of the contents of the container when the container has been filled with a carbonated beverage. However, it is also generally required that the closure can be removed quickly. Where the closure is engaged by rotation or by screw action, the requirement for easy and speedy access generally means that the closure should not have to be rotated more than one complete revolution in order to release it. However, in general, the smaller the amount of revolution required to remove the closure, the greater the danger that the closure will be missiled off due to the pressure of the container contents.

With this arrangement, the rotatable closure 100 of FIG. 4 may be engaged with the body member by a screw action which is effective to position each lug beneath a length of the screw thread 8 . Removal of the closure 100 is effected by a reverse screw action.
- the top member 102 of the closure is shaped to provide stiffness to the construction and, therefore, to provide the ability for the closure 100 to withstand the pressure within the beverage container.
- the top member 102 may have any suitable shape which imparts the necessary stiffness. For example, a double curve may be imposed on the top member and/or a star shape may be impressed therein.

Abstract
A container for a carbonated beverage has an interrupted external screw thread surrounding its mouth opening engageable with an internal screw thread of a rotatable closure. The rotatable closure is in two parts and has a stiffened top member and a separate, rotatable depending rim to rotatably engage on the container and hold the top member in sealing engagement with the opening of the container. To prevent missiling on opening, pressure venting means such as slots extending through the closure may be provided. Alternatively, the rotatable closure may be configured to have a two stage opening movement. As the rotatable closure is made in two parts it has a low opening torque.
Description
- The present invention relates to the use of a rotatable closure to close a container for carbonated beverages, to a container for carbonated beverages, and to a rotatable closure for a carbonated beverage container.
- British patent No. 2,254,594 discloses a container for beer and other beverages which is particularly suitable for dispensing carbonated beverages to a large number of people at a public venue. The container disclosed in the identified British patent is made of plastics material and has an unrestricted mouth opening such that the container itself can be used as the drinking vessel. The opening has an external screw thread proximate thereto and the proposal of British patent No. 2,254,594 is to provide a correspondingly threaded end closure.
- There are currently large numbers of designs of closures for containers, including many designs of closures arranged to be affixed and removed from the corresponding container by a screw action. However, none of the readily available closures behave entirely satisfactorily with a container of the type disclosed in the above identified British patent.
- The present invention seeks to provide closures which can be used satisfactorily with carbonated beverage containers.
- According to a first aspect of the present invention, there is provided the use of a rotatable closure to close a container for carbonated beverages, wherein said rotatable closure comprises a top member and a separate rim, the rim being held on the top member and being rotatable relative to the top member, and wherein said container has a body member having an opening at one end thereof, and external engagement means formed on said body member proximate to said opening, wherein cooperable engagement means are formed internally of the rim of said rotatable closure, and wherein the container opening is closed by engaging the engagement means of said rim with the engagement means of the container.
- The use of a rotatable closure of an embodiment of the invention, which has a separate, rotatable, rim ensures that the container can be reliably closed against the pressure of its contents, and yet be opened relatively easily. In this respect, to open the container it is only necessary to rotate the rim and not the top member of the closure. If the container has a wide mouth opening, the top member forms a large part of the closure. By this means, the opening torque of the closure is reduced quite considerably.
- The container may be fabricated from any suitable material, for example, from metal or glass. In a preferred embodiment, the container is fabricated from plastics material.
- Preferably, said opening defines an unrestricted mouth opening for the container. For example, the opening may have a diameter exceeding 30 mm, or 50 mm.
- In an embodiment, said cooperable engagement means on said rim and on the container are arranged such that said rotatable closure is engageable and removable from the container by rotating the rim of the rotatable closure relative to the opening of the container.
- As explained, the rotatable closure is removable from the container by rotation of the rim, and preferably, rotation of said rim through less than one complete revolution thereof is effective to enable removal of the closure.
- In one embodiment, the cooperable engagement means comprises an external screw thread provided on said container around said opening. The screw thread on the container may be continuous or interrupted. The screw thread on the container may vary in pitch.
- The cooperable engagement means on the interior of the rim of the closure, for cooperation with the screw thread, for example, on the container, may comprise a plurality of lugs and/or an internal screw thread.
- In a preferred embodiment, a plurality of lugs are spaced around the opening of the container, and an internal screw thread is provided on the interior of the rim of the closure for cooperation with said lugs.
- Preferably, to prevent missiling of the closure on opening, pressure venting means are associated with the closure. For example, said pressure venting means may comprise one or more slots extending through said closure, and/or through said container.
- Additionally and/or alternatively, said pressure venting means comprise means associated with said cooperable engagement means for imparting a two stage opening movement to said rotatable closure relative to the opening of the container.
- The present invention also extends to a container for carbonated beverages comprising a body member having an opening at one end thereof, and external engagement means formed on said body member proximate to said opening, and a rotatable closure engaged on said container to close the opening, the rotatable closure comprising a top member and a depending rim, and wherein cooperable engagement means are formed internally of the rim of said rotatable closure and engage the external engagement means to hold the rotatable closure on the container.
- As previously, the body member may be of any suitable material, for example of glass or metal. However, for use at public venues it is preferred that the body member be fabricated of plastics material.
- The rotatable closure defined above, and the rotatable closure incorporated in an embodiment of a container of the invention, may be fabricated, at least in part, of metal. Closures incorporating metal generally have a lower coefficient of friction than closures made entirely of plastics material and the use, therefore, of metal reduces the opening torque.
- The rim of the rotatable closure may be made of any suitable material, for example, of plastics or of metal.
- The top member of the rotatable closure is preferably suitably shaped to provide stiffness thereto.
- In a preferred embodiment, the top member of the rotatable closure is deformed inwardly. This deformation provides the closure with a large surface area and thereby stiffens the closure and enables it to withstand the pressure of the carbonated contents of the container.
- In a preferred embodiment, the inward deformation of the top member is utilised to form a seal between the closure and the container.
- Preferably, the engagement between the rotatable closure and the container is arranged such that the closure may be removed by rotating it through less than one complete revolution thereof. This ensures quick and easy removal of the closure, a feature which is very important if the container is being used to dispense beverages at a public venue.
- The container is also, preferably, provided with pressure venting means to prevent missiling of the closure. Preferably, the pressure venting means are associated with the closure. For example, slots may extend through the closure and/or the container. In one embodiment, these slots are adjacent to the engagement means of the closure.
- Additionally and/or alternatively, means may be associated with the engagement means of the closure to impart a two stage opening movement thereto. For example, such means may be arranged to halt an opening movement of the closure relative to the container opening. For example, appropriate stops may be provided on the closure and/or on the container. As the closure is rotated to effect opening, part of the closure or of the container will abut against the stops. This arrest of the opening movement is designed to provide for pressure venting. The effect of the stops can be overcome by, for example, pressing down on the closure whereby the rest of the opening rotation is enabled.
- In an embodiment, cooperable engagement means on said rim and on the container are arranged such that said rotatable closure is engageable and removable from the container by rotating the rotatable closure relative to the opening of the container. For example, said rotatable closure may be removable by rotating said closure relative to the periphery of the opening, and wherein rotation of said closure through less than one complete revolution thereof is effective to enable its removal.
- Preferably, the cooperable engagement means comprises an external screw thread provided on said container around said opening. The screw thread on the container may be continuous or interrupted.
- The cooperable engagement means on the interior of the rim of the closure, for cooperation with the screw thread, for example, on the container, may comprise a plurality of lugs and/or an internal screw thread.
- In an alternative embodiment, the cooperable engagement means comprise an internal screw thread on the rim of said rotatable closure.
- Said screw thread on the rim may be interrupted, and/or may vary in pitch.
- In this embodiment, said cooperable engagement means further comprise a plurality of lugs provided on said container and spaced around said opening, said lugs being engageable with said internal screw thread.
- The container as defined above may have any of the features of the use of the rotatable closure as defined above, and/or any of the features of the rotatable closure as defined below.
- Similarly, the use of the rotatable closure as defined above may incorporate any of the features of the container as defined above, and/or any of the features of the rotatable closure as defined below.
- The present invention also extends to a rotatable closure for a carbonated beverage container, said rotatable closure comprising a top member, and a peripheral rim depending relative to said top member, and wherein the top member is shaped to stiffen the closure.
- In an embodiment, said peripheral rim is separate from the top member and is held on the top member to be rotatable around the periphery thereof.
- The rotatable closure may be fabricated and configured as defined above.
- Embodiments of the present invention will hereinafter be described, by way of example, with reference to the accompanying drawings, in which:
- FIG. 1 shows schematically a carbonated beverage container with a closure therefor,

- The invention is described herein specifically with reference to a carbonated beverage container of plastics material as described, for example, in UK patent No. 2,254,594. However, whilst the present invention has been specifically designed for use with such a container, the invention is not limited to containers as described and claimed in the British patent. For example, a carbonated beverage container of the invention may be made of a plastics material, or of glass, or of metal, or of any other suitable material.
- FIG. 1 shows an example of a beverage container of plastics material for use for dispensing beer or other carbonated beverages. In this respect, the container comprises of substantially
cylindrical body member 2 of plastics material having a closed end 4 and a generallycircular mouth opening 6 at the end thereof opposed to said closed end 4. An interrupted external screw thread 8 is provided on thebody member 2 and surrounds, but is spaced from, themouth opening 6. - The container of FIG. 1 is also provided with a
closure 100 having an internal screw thread (not visible) arranged to engage the screw thread 8 of the container. Thus, when thebody member 2 has been filled, theclosure 100 can be engaged thereon by engaging the screw threads of the closure and of the body member and then rotating or screwing the closure to its closed position. When it is required to have access to the contents of the container, theclosure 100 is removed and may be discarded. - The construction and configuration of the
closure 100, and the method of its engagement on the container, has to be chosen with care to meet a number of desired criteria. It is, of course, required that theclosure 100 is able to withstand the pressure of the contents of the container when the container has been filled with a carbonated beverage. However, it is also generally required that the closure can be removed quickly. Where the closure is engaged by rotation or by screw action, the requirement for easy and speedy access generally means that the closure should not have to be rotated more than one complete revolution in order to release it. However, in general, the smaller the amount of revolution required to remove the closure, the greater the danger that the closure will be missiled off due to the pressure of the container contents. - Similarly, it is required that there be a seal between the closure and the container when the container is closed in order to keep the beverage pressurised. However, the greater and more effective the seal, the greater the risk that the required opening torque will be unacceptably large.
- FIG. 4 illustrates an embodiment of a two-
part rotatable closure 100 for use with a container as indicated in FIG. 1. Theclosure 100 comprises atop member 102, for example, made of a metal, which is generally in the form of a circular disc but has anannular channel 104 provided therein. Furthermore, thetop member 102 is also formed to have aradially extending flange 106. Thetop member 102 carries a dependingperipheral rim 108 which has two axially spaced, radially extendingflanges flange 106 of the top member to hold therim 108 relative to thetop member 102. On the internal annular surface of therim 108, engagement means, such as ascrew thread 120, are provided. Therim 108 is held on thetop member 102 to be freely rotatable relative thereto. - The engagement means may comprise a plurality of lugs arranged to engage with the screw thread8 on the
body member 2 of the container. Where the screw thread 8 is interrupted, for example as shown in FIG. 1, the lugs on the closure may be spaced apart by a distance substantially the same as the length of each length of the screw thread 8. With this arrangement, therotatable closure 100 of FIG. 4 may be engaged with the body member by a screw action which is effective to position each lug beneath a length of the screw thread 8. Removal of theclosure 100 is effected by a reverse screw action. - The
top member 102 of the closure is shaped to provide stiffness to the construction and, therefore, to provide the ability for theclosure 100 to withstand the pressure within the beverage container. In this respect, thetop member 102 may have any suitable shape which imparts the necessary stiffness. For example, a double curve may be imposed on the top member and/or a star shape may be impressed therein. Frequently, shapes in which thetop member 102 is inwardly deformed will be used as such shapes facilitate the incorporation of sealing means as described further below. - The embodiments described so far show the use of an interrupted screw thread on the
body member 2 of the container for engagement with a screw thread or with lugs provided on an inner surface of a rim of the closure. However, it will be appreciated, that any cooperable engagement means, which enable the closure to be reliably engaged on the container, and enable removal of the closure by a twisting action may be utilised. For example, threads may be provided on the body member or on the closure and such threads may be continuous or interrupted. The other of the closure and the body member may be provided with cooperating threads, with lugs, recesses, guides, or other formations. - However, there is an advantage to utilising a screw thread on one of the container and the closure, and lugs on the other of the closure or container, as such an arrangement enables pressure venting for the closure to be provided.
- In this respect, FIG. 2a shows part of the
body member 2 of a is container having a plurality oflugs 30 provided externally of thebody member 2 and around themouth opening 6. FIG. 2b shows an extended view of the neck showing thelugs 30, whereas FIG. 2c shows an extended view of the inner cooperating surface of a depending peripheral rim of a closure, as 100, which is provided with an interruptedscrew thread 40. Thisclosure 100 is to be used with thebody member 2 of FIG. 2a. - FIGS. 3a and 3 b show adjacent sections or lengths of the interrupted
screw thread 40 provided on the inner surface of the rim of theclosure 100. As can be seen, the lengths of thescrew thread 40 are shaped to guide thelugs 30 during opening and closing, and at one end, each length of thescrew thread 40 has an angleflat section 42 and at its other end, each length ofscrew thread 40 has a further flat 44 terminated in astop 46. Alug 30 of thebody member 2 of the container will lie on a respective angle flat 42 in the closed condition of the closure. - When the
closure 100 is to be opened, its dependingperipheral rim 108 is rotated relative to themouth opening 6 whereby eachlug 30 is moved along the corresponding length of thescrew thread 40 until thelug 30 is received in theposition 30′. In that position, thestop 46 prevents further relative rotation between the closure rim and the container. However, if the closure is then pressed downwardly, thelug 30 is positioned above thestop 46, and further rotation of the closure rim, and hence removal of the closure, can be achieved. This two stage opening of the closure allows pressure to be vented whilst the closure and the container are still engaged. Thus, thestops 46 are effective as anti-missiling stops. - It will be appreciated that in the arrangement shown in FIGS. 3a and 3 b, the lengths of
screw thread 40 are shaped to have a variable pitch. By this means, the removal of the closure from the body member employs a camming action derived from the variation in pitch. Of course, alternative constructions can be provided. - The particular screw thread and lug configuration illustrated is arranged to enable removal of the closure upon rotation thereof through less than one complete revolution. Preferably, removal is arranged to occur after about one quarter of one revolution of the closure.
- As is illustrated in FIG. 4, when the
closure 100 is in position closing a container, the periphery of the container's mouth opening, as 6, is received within theannular channel 104 as earlier described. In this respect, and as indicated in FIG. 4, a sealingcompound 122 may be received within thechannel 104. The sealing of the container in the closed position of theclosure 100 can thereby be ensured. - Alternative sealing means, such as a rubber ring (not shown), may be housed within the
channel 104. - To open a container closed by the
closure 100, therim 108 is grasped, in normal manner, and is rotated relative to the container. However, whereas with a conventional one part closure the whole of the closure has to be rotated, opening of the container utilising a closure as 100 can be achieved by rotation of therim 108 only whereby the opening torque is considerably reduced. - The
closure 100 shown in FIG. 4 may additionally and/or alternatively be provided with pressure venting means, for example, in the form of slots (not shown) extending through therim 108 from its inner to its outer surface. Such slots, for example, may extend upwardly from an opening in the inner surface of therim 108 and exit in theflange 110. When therim 108 is rotated to open the container, the action of thescrew thread 120 on the corresponding thread or lugs of the container lifts the closure and may be sufficient to partially or fully break any seal between the closure and the container. This enables pressure from the interior of the container to be vented by way of the vent slots in the closure. Continued rotation of therim 108 then effects removal of theclosure 100. - Of course, the pressure venting slots may be incorporated in any suitable area of the closure and/or container. For example, pressure venting slots may extend through the
screw thread 120 of the closure, and/or through the corresponding screw thread or other engagement means of the container. - The
rim 108 of the closure may be made of any suitable material. For example, therim 108 may be made of a plastics material. Alternatively, therim 108 may be made of metal, for example, it may be a spun or pressed metal threaded band. - FIG. 5 shows schematically an alternative embodiment of the
closure 100 in which thetop member 102 is inwardly deformed. In the embodiment shown in FIG. 5, thetop member 102 is inwardly indented. FIG. 6 shows an alternative embodiment in which thetop member 102 is inwardly domed. In both of the embodiments of FIGS. 5 and 6, the inward deformation of thetop member 102 increases the surface area of the top member and hence increases the stiffness of the closure and its ability to withstand pressure as described earlier. - FIG. 7 shows a still further embodiment of the
closure 100 in which theradially extending flange 110 of therim 108 extends over thetop member 102. In the embodiment illustrated in FIG. 7, the periphery of the mouth opening of acontainer 160 is shown received within theannular channel 104 of theclosure 100. - FIGS. 8 and 9 show an embodiment of a
rotatable closure 200 of the present invention. Specifically, FIG. 8 shows part only of theclosure 200 engaging on the annular periphery of themouth opening 6 of a container as 2 to close the mouth opening. - As previously, the
rotatable closure 200 is a two-part closure having atop member 202 from which a dependingperipheral rim 208 extends. Theclosure 200 shown in FIG. 8 acts as a bore and top seal which is dynamically sealed in and on themouth opening 6. - In the embodiment shown in FIG. 8, the engagement means on the exterior of the annular periphery of the
mouth opening 6 are not shown. However, it will be appreciated that such engagement means are provided and are arranged to be engaged byscrew threads 220 provided on the dependingrim 208. - The
top member 202 of theclosure 200 comprises, as can be seen in FIG. 9, a substantially circular, planar,disc 212 with a flat outer surface and a plurality of stiffeningribs 210 on its internal surface. Thetop member 202 has a radially extending,circumferential portion 213 extending around the outer circumference thereof. A first, innerannular rim 214 and a second, outerannular rim 216 each depend downwardly from saidcircumferential portion 213. In the embodiment illustrated, there are six radially extendinginternal ribs 210 which extend from the centre of thedisc 212 to the downwardly dependinginner rim 214. It will be seen that the tworims annular channel 224 which extends annularly around thecircumferential portion 213 of thetop member 202. - The
top member 202 may be made of a plastics material or of a metal. Where it is formed of a plastics material it may be a coextrusion or co-injection of foil and polypropylene or other plastics material. It is possible, for example, to mix the plastics material with an oxygen scavenger before moulding thedisc 212. - As the top, external surface of the
central disc 212 is substantially planar, instructions for use and/or advertising material may be affixed to the external surface of thetop member 202. - Preferably, the external diameter of the
inner rim 214 of thetop member 202 is the same as, or slightly larger than, the internal diameter of themouth opening 6 of the container. This means that thetop member 202 has to be forced into position during closure of the container whereby a very good and efficient seal is produced within themouth opening 6. - As described previously, a sealing member, such as a gasket (not shown), may be provided in the
channel 224 in thetop member 202. Additionally and/or alternatively, sealing compound, such ascompound 122, may be provided in thechannel 224. In the embodiment shown in FIG. 8, the top of themouth opening 6 of the container is provided with aprojection 260. This projection is made stiff so that it can deform the surface of thechannel 224 with which it comes into contact. In this way, further enhanced sealing of the closure on themouth opening 6 can be achieved. - As previously, the
rim 208 of the closure is engaged on and depends from thetop member 202 and is rotatably engaged by way ofscrew threads 220 on screw threads (not shown in FIG. 8) on the outer periphery of themouth opening 6. - It will be seen from FIG. 8 that the
rim 208 has aradially extending flange 230 which, in the closed position of theclosure 200, engages on the top, external surface of the radially extendingcircumferential portion 213 of thetop member 202. Thus, when theseparate rim 208 of the closure is engaged on themouth opening 6 to close the container, therim 208 holds thechannel 224 of thetop member 202 in position on themouth opening 6 to make and retain a pressure withstanding seal therebetween. Where the contents of the container are carbonated, the pressure of the contents will tend to push theinner depending rim 214 of thetop member 202 against themouth opening 6 whereby a further pressure seal is made and retained. The strengtheningribs 210 on thetop member 202 prevent bowing of thedisc 212 outwardly by the pressure of the contents. - Where the contents of the container are beer, for example, it is generally preferred to fill the container at a temperature of 3° C. or lower to maintain its carbonation during filling. However, the container has to be capable of withstanding the pressure of its contents and maintaining the seal of its closure at temperatures up to 40° C. In a preferred embodiment, at least the material of the
separate rim 208 of theclosure 200 and of the body of the container defining themouth opening 6 is the same so that the two elements react similarly as the container is subjected to differing temperatures. Preferably, both the container body and at least theseparate rim 208 of the closure are of an appropriate plastics material. - It will be appreciated that the container and its
closure 200, as illustrated in FIGS. 8 and 9, provide sealing against the pressure of the container contents both within the inner diameter, or bore, of themouth opening 6 and at the top surface of the mouth opening. This top and bore seal is, because of the construction of theclosure 200, dynamically reactive to the pressure of the contents. Nevertheless, because only theseparate rim 208 of the closure has to be rotated to release the closure, opening of the container by removal of theclosure 200 is relatively simple. Once therim 208 is rotated in an opening direction, the top seal begins to be released whereby the bore seal can similarly be released. In general, the construction of the closure and the sequential release of the seals thereof enable gas to be vented from the container so that there is no danger of missiling of the closure. However, pressure venting means to further allow venting on opening and thereby prevent missiling may also be provided. - FIG. 10 show an alternative embodiment, similar to that of FIG. 8, but with an
annular projection 270 formed on an interior surface of theseparate rim 208. When theclosure 200 is in its closed position, theouter depending rim 216 of thetop member 202 is pinched between theseparate rim 208 and themouth opening 6 of the container to assist in sealing the container. The pinching action is able to maintain the seal even where there are different amounts of creep or contraction in the plastics material of the container and the closure. - It will be appreciated that variations to and modifications in the embodiments as described and illustrated may be made within the scope of the invention as defined in the appended claims.
