- a closure assembly adapted to be applied to a mouth of a container (eg for liquid), such as a neck of a bottle according to the preamble of claim 1.
- a container eg for liquid
- Such an assembly is known from GB 2274 837A .
- the invention consists in a closure assembly according to the combination of features of claim 1.
- a used container such as a bottle intended to contain a liquid, such as a valuable liquid, (eg spirits such as alcoholic beverages)
- a liquid such as a valuable liquid, (eg spirits such as alcoholic beverages)
- Attempts to provide closures which make such re-filling difficult are not always proof against determined tampering. While it is considered advantageous to provide a tamper-indicating means which provides evidence that the bottle and its original contents are intact, if the bottle is resealable with a substitute cap or closure, there may be little to indicate to a purchaser that the bottle has been tampered with and that the contents may be inferior to the original contents.
- Patent US 6 276 544 B discloses a security closure for a glass bottle comprising a cap having internal threading with a predetermined large number of starts mating with external threading on the bottle, the cap being connected, by means of a line of weakening, to a sleeve restrained axially and angularly on the bottle, the closure further comprising lead-in means in the sleeve mating with matching lead-in means on the bottle in order to orient the cap and the sleeve angularly relative to the bottle when the cap and the sleeve are fitted axially on the bottle.
- Document GB 2 366 287 A discloses a tamper-evident anti-refill closure comprising a sleeve and a valve seat body, wherein the sleeve is adapted to lie around the mouth of a container and is provided with at least one inwardly projecting resilient means, engageable with an outer lip portion of the container mouth whilst the valve seat body is at least partially receivable within the neck portion of the container, the sleeve at least partially surrounding the valve seat body.
- closure assembly (or tamper-evident device) according to claim 1.
- the Applicant has named the device of the invention the "ALUSNAP” (Trade Mark) non-refillable closure assembly or tamper-evident device.
- the first outer sleeve and second outer sleeve are separate one from the other prior to initial opening of the closure assembly.
- first outer sleeve has open first and second ends and the second outer sleeve has a first closed end and second open end.
- the container closure member includes a circumferential groove, which further provides a circumferential lip portion located below and adjacent to the circumferential groove.
- the initially adjacent portions comprise adjacent respective circumferential edges of the first and second outer sleeves.

Abstract
Description
- The present invention relates to a closure assembly adapted to be applied to a mouth of a container (eg for liquid), such as a neck of a bottle according to the preamble of claim 1. Such an assembly is known from
GB 2274 837A - For various reasons, it may be desirable to ensure that a used container, such as a bottle intended to contain a liquid, such as a valuable liquid, (eg spirits such as alcoholic beverages), is not re-filled with a replacement quantity of another liquid, the characteristics and quality of which may differ from the original contents. Attempts to provide closures which make such re-filling difficult are not always proof against determined tampering. While it is considered advantageous to provide a tamper-indicating means which provides evidence that the bottle and its original contents are intact, if the bottle is resealable with a substitute cap or closure, there may be little to indicate to a purchaser that the bottle has been tampered with and that the contents may be inferior to the original contents.
- It has, therefore, been found desirable to provide a closure which cannot be removed without an extreme level of effort, or breakage being caused to the bottle. Such an arrangement is shown, for example, in
GB Patent No. 2 274 837 - Other documents available in the prior art are document
US 6 276 544 B and documentGB 2 366 287 A -
Patent US 6 276 544 B discloses a security closure for a glass bottle comprising a cap having internal threading with a predetermined large number of starts mating with external threading on the bottle, the cap being connected, by means of a line of weakening, to a sleeve restrained axially and angularly on the bottle, the closure further comprising lead-in means in the sleeve mating with matching lead-in means on the bottle in order to orient the cap and the sleeve angularly relative to the bottle when the cap and the sleeve are fitted axially on the bottle. - Document
GB 2 366 287 A - Whilst it is very important that an original closure cannot be removed without visible damage or breakage being caused either to the closure and/or to the bottle, it has been found that a closure that cannot readily be removed will become the target of attempts to re-fill the container by overcoming the feature provided in the closure intended to hinder or prevent such refilling. Therefore, in addition to providing devices to prevent re-filling of bottles, there is a need to provide such devices with further tamper-indicating features which, while not acting in any preventive role, give a clear irremovable and/or irreversible indication that a bottle has been opened since being originally filled with the genuine contents. Such clear indicators have been somewhat lacking in previous closure designs.
- Furthermore, there is a need for simple designs of closure assemblies allowing easy and reliable manufacture, assembly and fitting to bottle necks. Such simplicity has been somewhat lacking in previous closure designs.
- It is an object of the present invention to provide an improved closure assembly which does not have any parts which are frangible and/or removed upon initial opening and which are liable to be reattached by counterfeiters or the like in a way suggesting that the closure assembly had not previously been opened.
- It is also an object of the present invention to obviate or at least mitigate at least one of the aforementioned problems/disadvantages in the prior art.
- According to the present invention there is provided a closure assembly (or tamper-evident device) according to claim 1.
- The Applicant has named the device of the invention the "ALUSNAP" (Trade Mark) non-refillable closure assembly or tamper-evident device.
- The first outer sleeve and second outer sleeve are separate one from the other prior to initial opening of the closure assembly.
- Preferably the first outer sleeve has open first and second ends and the second outer sleeve has a first closed end and second open end.
- The container closure member includes a circumferential groove, which further provides a circumferential lip portion located below and adjacent to the circumferential groove.
- The initially adjacent portions comprise adjacent respective circumferential edges of the first and second outer sleeves.
- The first and second circumferential edges are prior to initial opening located in the circumferential groove and adjacent one another.
- Preferably, during an initial container opening operation, the first circumferential edge expands or rides over the circumferential lip portion and then recoils or retracts preferably to substantially its original circumferential position so as to become positioned circumferentially behind the circumferential lip portion. Alternatively or additionally during an initial container opening operation, the circumferential lip portion contracts or rides under the first circumferential edge and then recoils or expands preferably to substantially its original circumferential position so as to become positioned circumferentially ahead of the first circumferential edge. This action positions the circumferential lip longitudinally between the first and second circumferential edges in an obstructive manner such that when the container is reclosed by re-applying the closure member, the first and second outer sleeves are spaced apart at least by the circumferential lip portion located therebetween.
- By this arrangement after reclosure the first and second circumferential edges are no longer adjacent but spaced thus revealing a void or gap between the first and second circumferential edges. This visual indicator evidences that the closure assembly (and container) has been opened and reclosed.
- The first circumferential edge of the first outer sleeve may provide a circumferential first beaded portion on the first outer sleeve, and in a same manner the second circumferential edge of the second outer sleeve may provide a circumferential second beaded portion on the second outer sleeve.
- The first and second outer sleeves may comprise any suitable material, and preferably the material comprises a metal, or metallic based material.
- Preferably the metal or metallic based material substantially comprises aluminium or an alloy thereof, and particularly rolled aluminium.
- Advantageously, aluminium provides a good medium for application of printing dyes, inks, paints or the like such that messages, logos, images, names, and other information may be carried by the first and second outer sleeves. A message may for example, comprise arrows indicating a direction of rotation for opening of the closure assembly.
- The container closure member may be a cap which desirably includes a threaded portion which allows a rotational movement (normally anti-clockwise) of the cap during a container opening operation.
- The closure assembly may include a non-refillable device providing a pouring outlet device adapted to be secured to the mouth of a container for liquid. The container closure member may be a cap adapted to close an outlet of the pouring outlet device, and the first outer sleeve may be adapted to receive at least part of the pouring outlet device. The outlet may be substantially annular and the cap may carry on an inner facing end an annular seal removably receivable within the annular outlet.
- Preferably the second outer sleeve member is adapted to receive at least part of the cap.
- The cap is generally received in a tight interference fit to the second outer sleeve, but may be optionally rotatable with respect to the second outer sleeve upon application of sufficient force.
- Desirably the pouring outlet device is made in one piece with the sleeve, eg by injection moulding.
- Preferably the non-refillable device further comprises a valve seat body which is at least partially receivable within at least part of the neck portion of the container, and wherein the valve seat body is at least partially surrounded by the sleeve.
- Preferably at least one moveable valve member is provided within the valve seat body.
- Preferably there are provided means for retaining the first outer sleeve in longitudinal relation to the sleeve, eg an end of the first outer sleeve at least partially formed over an end of the sleeve.
- Preferably the first and second circumferential edges of the first and second sleeves are before an initial opening of the closure assembly located within the circumferential groove provided on the cap, and are substantially adjacent. This positioning ensures that when the container is initially opened by relative twisting of the cap and sleeve, the second circumferential edge of the second outer sleeve remains within the groove provided on the cap, and the first circumferential edge of the first outer sleeve progressively resiliently may be caused to move circumferentially outward and out of the groove provided on the cap as the cap is removed away from the pouring outlet device and the first portion. Alternatively or additionally the circumferential lip portion may progressively be caused to move circumferentially inward. On removing the contact between the cap and the first circumferential edge of the first outer sleeve, the first circumferential edge retracts to a substantially reduce circumference, (eg its original circumference), such that the resulting circumference is less than that of a cap portion which is located below the groove. This cap portion is preferably provided as the circumferential lip on the cap.
- When the cap is re-applied to the pouring outlet device, a stop position is reached when the circumferential lip portion of the cap rests, sits or abuts upon the first circumferential edge of the first outer sleeve, thus preventing the cap being returned to its original unopened starting position. A longitudinal gap or void therefore remains between the first and second outer sleeves thus exposing a circumferential part of the cap, which includes at least part of the circumferential lip which was originally encased or enclosed within the first circumferential edge and an original cap seating surface of the pouring device.
- Advantageously the exposed circumferential part of the cap may be distinctly coloured and/or printed with information, promotional messages or the like.
- The fixing means may comprise first means for fixing the sleeve on the container so as to restrain rotational movement of the sleeve with respect to the neck portion of the container.
- The fixing means may also comprise second means for fixing the sleeve on the container so as to restrict longitudinal movement of the sleeve with respect to the mouth of the container.
- Preferably the second means for fixing the sleeve are in the form of at least one projecting means projecting inwardly of said sleeve, said at least one projecting means being moveable radially of the sleeve in a stiffly resilient manner and being engagable with an outer lip portion of said container.
- Preferably the first outer sleeve fits with the sleeve by means of an interference fit between an outer surface of the sleeve and an inner surface of the first outer sleeve.
- Preferably the cap has thereon a threaded portion which engages with a corresponding threaded portion on the pouring outlet.
- It is desired that the first and second outer sleeves are aesthetically pleasing, and as such, it is preferred that the first and second outer sleeves comprise metal foil.
- It is preferred that there are provided means for assembling the sleeve and valve seat body together prior to application to the container.
- Preferably the projecting means are provided on an inner wall of the sleeve to resiliently engage the neck portion of the container.
- Preferably the sleeve contains one or more circumferential apertures around the sleeve, which are defined between axially extending portions of the sleeve. The/each projecting means may be provided adjacent to an edge of one of the apertures.
- It is preferred that each projecting means is positioned on a lower circumferential edge of one of the apertures.
- Typically the pouring outlet device comprises a circumferentially extending pouring lip.
- The sleeve may further be provided with a tubular body position inwardly and preferably concentrically of the pouring outlet device and wherein the tubular body is attached to an inner surface of the sleeve via a plurality of webs.
- Further, a bore of the tubular body may be closed, and in particular, an outer facing wall which closes the tubular body is preferred.
- Alternatively the tubular body may be solid or a wall may be positioned at any convenient axial location along the tubular body.
- Preferably the closed wall of said tubular body is positioned to be substantially flush with the circumferential pouring lip.
- Conveniently said tubular body is provided with a circumferentially extending brim which is positioned on the lower outer edge of said tubular body. Conveniently webs connect an inner surface of the sleeve to the brim and to the tubular body.
- Conveniently each web is configured to provide a bracket upon which the brim fixedly sits.
- The sleeve is further conveniently provided with a plurality of ribs or ridges formed on an inner surface thereof, preferably arranged circumferentially around the sleeve and having their long axes arranged substantially axially to said sleeve.
- These ribs or ridges, in use, may co-act with raised pips, ridges or the like, on an outer surface of the container (eg a "glass finish" of the bottle) to seek to prevent undesired rotational movement of the sleeve.
- The valve seat body may comprise a tubular portion, a free end portion of which provides a valve seat adapted to be contacted in a sealing manner by a valve member captive in said tubular portion.
- The valve seat is preferably a circumferentially extending flange, which extends radially inwardly of the tubular portion. In one embodiment such a valve seat is positioned at one end of the tubular portion, and that end of the tubular portion is closed except for a circular aperture.
- It will be understood that the tubular portion is adapted to be received substantially within the mouth portion of the container.
- The tubular portion may further comprise at least one engagement means on an outer surface thereof to engage an inner surface of the container in an interference fashion.
- The engagement means are preferably radially extending circumferential ribs.
- At or near to an end of the tubular portion distant from the valve seat is provided a substantially concentric further tubular body of greater diameter than the tubular portion, and an inner surface of the further tubular body is connected to an outer surface of the tubular portion by one or more further webs.
- It is preferred that a first end of the further tubular body is connected to an outer surface of the tubular portion by an annular flange.
- Thus, in one embodiment of the present invention, such construction provides a circumferential trough defined between the outer surface of the tubular portion and the inner surface of the further tubular body with the flange forming a trough floor. The trough is divided into smaller arc-shaped troughs by the further webs.
- Such a trough helps prevent insertion of objects into the container through the closure assembly.
- Preferably a second end of the further tubular body is arranged substantially flush with an end of the tubular portion distant from the valve seat.
- In use the tubular portion forms an inner sleeve of the assembled closure assembly.
- Advantageously, an outer surface of the further tubular body interference interacts with an inner surface of the sleeve.
- Conveniently, a radially extending circumferential rim is located on an outer edge of an end of the further tubular body, which, in an assembled closure assembly is seated against a lower surface of a radially extending circumferential rim provided on an inner surface of the sleeve.
- According to an advantageous embodiment of the present invention, there is provided a container including a closure assembly according to the first aspect of the present invention.
- The container is preferably a container for liquid.
- The container may be a bottle, eg a glass bottle, and may be adapted for containment of liquid, such as alcoholic drinks or beverages, eg spirits such as vodka, whisky, brandy, gin or the like.
- According to another embodiment of the present invention there is provided a combination of a container and a closure assembly according to the first aspect of the present invention.
- According to a further embodiment of the present invention there is provided an alcoholic drinks product comprising an alcoholic substance packaged in the combination according to the previous embodiment of the present invention.
- A method of manufacturing the closure assembly according to the present invention may comprise the steps of:
- (a) providing an outer sleeve member;
- (b) providing a pouring outlet device and a sleeve adapted to be secured to a mouth and neck portion of a container for liquid and a container closure member releasably securable to the pouring outlet device and/or sleeve;
- (c) disposing the pouring outlet device, sleeve and container closure member at least partly within the outer sleeve member;
- (d) forming the outer sleeve member into a first outer sleeve and a separate second outer sleeve.
- This method is particularly advantageous in mass production.
- Preferably step (d) is carried out using a first cutting tool such as a blade of a machine tool.
- Preferably step (d) comprises:
- forming a cut around a portion of the outer sleeve member so as to form adjacent first and second circumferential edges on the first and second outer sleeves.
- Advantageously, the first and second edges are formed in a groove carried on the container closure member (prior to initial opening).
- Advantageously the first and second circumferential edges are of reduced diameter compared to at least adjacent portions of the first or second outer sleeve, respectively.
- Preferably after step (c) the method also comprises the step of:
- (e) forming an end of the first outer sleeve over an end of the sleeve so as to retain the first outer sleeve and the sleeve in longitudinal relation.
- Preferably step (e) is carried out using a second cutting tool such as a further blade of a machine tool.
- Steps (d) and (e) may be undertaken substantially simultaneously.
- The closure assembly so formed may comprise a unitary assembly for snap-on application to a mouth and neck portion of a container.
- Advantageously, it is here described a method of bottling using the present invention and comprising:
- (a) providing a closure assembly according to the present invention;
- (b) providing a bottle;
- (c) filling the bottle with a liquid;
- (d) closing the bottle by applying the closure assembly to a mouth and neck of the bottle.
- An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawings, which are:
- Figure 1
- a cross-sectional view a closure assembly according to an embodiment of the present invention during an initial step of manufacture;
- Figure 2
- a cross-sectional view of the closure assembly of
Figure 1 during an intermediate step of manufacture; - Figure 3
- a cross-sectional view of the closure assembly of
Figure 1 after manufacture and prior to initial opening; - Figure 4
- an exploded perspective view of the closure assembly of
Figure 3 in combination with a bottle having a neck and mouth; and - Figure 5
- a cross-sectional view of the closure assembly of
Figure 3 applied to the bottle ofFigure 4 prior to initial opening. - Referring initially to
Figures 3 ,4 and5 , there is shown a closure assembly (or tamper-evident device), generally designated 5, according to an embodiment of the present invention. Theclosure assembly 5 is adapted to be applied to a mouth andneck portion bottle 15 for liquid. Theclosure assembly 5 comprises asleeve 20 adapted to lie substantially concentrically with respect to themouth 10 and provided with means for fixing thesleeve 20 on thecontainer 15. Theclosure assembly 5 further comprises a firstouter sleeve 25 being a substantially tight interference fit with thesleeve 20 but rotatable with respect thereto upon application of sufficient rotational force. Theclosure assembly 5 also comprises a secondouter sleeve 30 separate from the firstouter sleeve 25 and associated with acontainer closure member 35. Between the initially unopened first and secondouter sleeve line 31 formed as will hereinafter be described. Thecut line 31 extends 360° around theclosure assembly 5 and separates the first and secondouter sleeve cut line 31 may be unperceivable or at least almost unperceivable by the naked eye. There are also provided means for spacing apart initially adjacent portions of the first and secondouter sleeves closure assembly 5 after an initial opening of thecontainer 15 as will hereinafter be described in greater detail. - The Applicant has named the
closure assembly 5 of the present invention the "ALUSNAP" (Trade Mark) non-refillable closure assembly or tamper-evident device. - The first
outer sleeve 25 has open first and second ends 40,45, and the second outer sleeve has a firstclosed end 50 and a secondopen end 55. - The
container closure member 35 includes acircumferential groove 60, and further provides acircumferential lip portion 65 located below and adjacent to thecircumferential groove 60. - The initially adjacent portions comprise initially adjacent respective
circumferential edges outer sleeves circumferential edges circumferential groove 60 and are substantially adjacent one another. - During an initial container opening operation, the first
circumferential edge 70 expands or rides over thecircumferential lip portion 65 and then recoils or retracts to substantially its original circumferential position so as to become positioned radially behind thecircumferential lip portion 65. Alternatively or additionally during an initial container opening operation, thecircumferential lip portion 65 contracts or rides under the firstcircumferential edge 70 and then recoils or expands to substantially its original circumferential position so as to become positioned radially ahead of the firstcircumferential edge 70. This action or these actions position thecircumferential lip portion 65 longitudinally between the first and secondcircumferential edges container 15 is reclosed by re-applying theclosure member 35, the first and secondouter sleeves circumferential lip portion 65 located therebetween. - By this arrangement after reclosure the first and second
circumferential edges groove 60 andlip portion 65 between the first and secondcircumferential edges - The first
circumferential edge 70 of the firstouter sleeve 25 may in a modification provide a first circumferential beaded portion on the firstouter sleeve 25 adjacent firstcircumferential edge 70, and in a same manner the secondcircumferential edge 75 of the secondouter sleeve 30 may provide a second circumferential beaded portion on the secondouter sleeve 30 adjacent secondcircumferential edge 75. - The first and
second sleeves outer sleeves - The
container closure member 35 is in the form of a cap which includes an internally threadedportion 85 which allows a rotational movement (normally anti-clockwise) of thecap 35 during a container opening operation, and a contra-rotational movement (normally clockwise) of thecap 35 during a container closing operation. - The
closure assembly 5 include anon-refillable device 90 providing a pouringoutlet device 95 adapted to be secured to themouth 10 of thecontainer 15 for liquid. Thecontainer closure member 35 is adapted to close anoutlet 100 of the pouringoutlet device 95, the firstouter sleeve 25 optionally being located to receive at least part of the pouringoutlet device 95. Theoutlet 100 is substantially annular and thecap 35 carries on an inner facing end 105 anannular seal 110 removably receivable within theannular outlet 100. Theannular outlet 100 defines a circumferential pouringlip 101. - The second
outer sleeve 30 is adapted to receive thecap 35. Thecap 35 is generally received in a tight interference fit to the secondouter sleeve 30, but may be rotatable with respect to the secondouter sleeve 35 upon application of sufficient force. For example, upon reclosure of theclosure assembly 5, whencircumferential lip portion 65 abuts firstcircumferential edge 70 further reclosure movement (eg clockwise turning of second outer sleeve 25) causesclosure member 35 to remain stationery andouter sleeve 25 to rotate relative thereto. Further, the secondcircumferential edge 75 maintains the secondouter sleeve 30 in longitudinal relation with theclosure member 35. - The pouring
outlet device 95 is made in one piece with thesleeve 20, eg by injection moulding. - The
non-refillable device 90 further comprises avalve seat body 115 which is at least partially receivable within at least part of theneck portion 11 of thecontainer 15, thevalve seat body 115 being at least partially surrounded by thesleeve 20. First and secondmoveable valve members valve seat body 115. Thefirst valve member 135 comprises a spherical body while thesecond valve member 136 comprises a finned tubular body having a downwardly directed closed frustonical lower end and an open upper end which may be received by thefirst valve member 135. - A non-return valve is formed from the
valve seat body 115 andvalve members bottle 15, and which while allowing liquids to flow from thebottle 15 in a pouring operation, restricts in-flow of liquid into thebottle 15 by rudimentary unauthorised filling operations or even more sophisticated methods which may involve attempted insertion of objects, tubes or the like into thebottle mouth 10. - There are provided means for retaining the first
outer sleeve 25 in longitudinal relation to thesleeve 20, eg an end 26 of the firstouter sleeve 25 formed (bent) over anend 120 of thesleeve 20. - The first and second
circumferential edges outer sleeves closure assembly 5, located within thecircumferential groove 60 provided on thecap 35, and are substantially adjacent. This positioning ensures that when thecontainer 15 is initially opened by relative twisting of thecap 35 andsleeve 20, the secondcircumferential edge 75 of the secondouter sleeve 30 remains within thegroove 60 provided on thecap 35, and the firstcircumferential edge 70 of the firstouter sleeve 25 progressively resiliently may be caused to move circumferentially outward and out of thegroove 60 provided on thecap 35 as thecap 35 is removed away from the pouringoutlet device 95 and the firstouter sleeve 25 portion. Alternatively or additionally as mentioned above, thecircumferential lip portion 65 may progressively resiliently move circumferentially inward. On removing the contact between thecap 35 and the firstcircumferential edge 70 of the firstouter sleeve 25, the firstcircumferential edge 70 retracts to a substantially reduced circumference (eg its original circumference), such that the resulting circumference is less than that of a cap portion which is located below thegroove 60, egcircumferential lip portion 65. - When the
cap 35 is re-applied to the pouringoutlet device 95, a stop position is reached when thecircumferential lip portion 65 of thecap 35 rests, sit's or abuts upon the firstcircumferential edge 70 of the firstouter sleeve 25, thus preventing thecap 35 being returned to its original starting (unopened) position. A longitudinal gap or void (not shown) therefore remains between the first and secondouter sleeves cap 35, which includes at least part of thecircumferential lip portion 65 which was originally encased or enclosed within the firstouter sleeve 25. A further void (not shown) also exists between a lower edge of thecap 35 and anoriginal cap 35seating surface 120 of the pouringoutlet device 95. - Advantageously the exposed circumferential part of the
cap 35 may be distinctly coloured and/or printed with information, promotional messages or the like. - The fixing means comprise first means 125 for fixing the
sleeve 20 on thecontainer 15 so as to restrain rotational movement of thesleeve 20 with respect to theneck portion 11 of thecontainer 15. - The fixing means also comprise second means 130 for fixing the
sleeve 20 on thecontainer 15 so as to restrict longitudinal movement of thesleeve 20 with respect to themouth 10 of thecontainer 15. The second means 130 for fixing thesleeve 20 are in the form of at least one projecting means 130 projecting inwardly of saidsleeve 20, said at least one projecting means 130 being moveable radially of thesleeve 30 in a stiffly resilient manner and being engagable with anouter lip portion 12 of saidcontainer 15. - The first
outer sleeve 25 fits with thesleeve 20 by means of an interference fit between anouter surface 140 of thesleeve 20 and aninner surface 145 of the firstouter sleeve 25. - The
cap 35 has therein threadedportion 85, which engages with a corresponding threadedportion 150 on the pouringoutlet device 95. - It is desired that the first and second
outer sleeves outer sleeves - There are provided means 146 for assembling the
sleeve 20 andvalve seat body 115 together prior to application to thecontainer 15, such as co-acting ribs and grooves carried by each. - The projecting means 130 are provided on an
inner wall 15 of thesleeve 20 to resiliently engage theneck portion 11 andouter lip portion 12 of thecontainer 15. - The
sleeve 20 contains one or morecircumferential apertures 115 around thesleeve 20, which are defined between axially extending portions of thesleeve 20. The/each projecting means 130 are provided adjacent to an edge of one of theapertures 115. - As can be seen in this embodiment each projecting means 130 is positioned on a lower
circumferential edge 160 of one of theapertures 155. - The
sleeve 20 further carries atubular body 165 positioned inwardly and substantially concentrically of the pouringoutlet device 95. Thetubular body 165 is attached to aninner portion 170 of thesleeve 20 or pouringoutlet device 95 via a plurality ofwebs 175. Abore 180 of thetubular body 165 is closed by an outer facingwall 185. In a modification thetubular body 165 may be solid or a wall may be positioned at any convenient axial location along thetubular body 165. Theclosed wall 185 of saidtubular body 165 is positioned to be substantially flush with the circumferential pouringlip 101. - The
tubular body 165 is provided with acircumferentially extending brim 190 which is positioned on the lowerouter edge 195 of saidtubular body 165. Conveniently thewebs 175 connect aninner surface 200 of thesleeve 20 to thebrim 190 and to thetubular body 165. Eachweb 175 is configured to provide a bracket upon which thebrim 190 fixedly sits. - The
sleeve 20 is further conveniently provided with a plurality of ribs (or ridges) 205 formed on aninner surface 210 thereof, in this embodiment arranged circumferentially around thesleeve 20 and having their long axes arranged substantially axially to saidsleeve 20. Theseribs 205, in use, form first means 125 for anti-rotation co-act with raised pips, ridges or the like 13, on an outer surface of the container 15 (comprising a so-called "glass finish" of the bottle) to seek to prevent undesired rotational movement of thesleeve 20. - Some minor rotational play in either a clockwise or anticlockwise direction may occur until a stop position is found by a rib or
ribs 205 acting against a ridge orridges 13. However, continued application of force will cause the firstouter sleeve 25 and/or the secondouter sleeve 30 to rotate relative to thesleeve 20 and/orcap 35, respectively. - The
valve seat body 115 comprise atubular portion 210, afree end portion 215 of which provides avalve seat 220 adapted to be contacted in a sealing manner byfirst valve member 135 captive in thetubular portion 210. - The
valve seat 220 comprises acircumferentially extending flange 221, which extends radially inwardly of thetubular portion 210. In this embodiment thevalve seat 220 is positioned at one end of thetubular portion 210, and that end of thetubular portion 210 is closed except for acircular aperture 225. - The
tubular portion 210 is adapted to be received substantially within themouth 10 portion of thecontainer 15. Thetubular portion 210 further comprises at least one engagement means 230 on an outer surface 235 thereof to engage aninner surface 240 of thecontainer 15 in an interference fashion. The engagement means 230 comprise radially extending circumferential ribs. - At or near to an end of the
