Abstract

Packaging (14) for a fluid container (10), the packaging (14) having at least one predetermined line of weakness (20, 22, 40, 42) defining a portion of the packaging which is adapted to form a spout for the fluid container. The fluid container (10) is preferably a wine bottle. A method is disclosed of forming a spout for a fluid container (10) comprising breaking the packaging along at least one predetermined line of weakness (20, 22, 40, 42) to remove a portion of the packaging, and inserting the removed portion of the packaging into an outlet of the fluid container to form a spout.

Description

The present invention relates to a capsule for a fiuid container, and in particular a capsule for a bottle containing a drink.
A problem often encountered when pouring a liquid from a container is that a small amount of the liquid drips or runs from the outlet of the container down the exterior of the container after pouring is stopped. This can lead to a number of problems such as damage to labels on the container, which could have particularly harmful effects in the case of a medicine. Furthermore, the presence of fluid on the outside of the container can be dangerous as it may lead to handling accidents. Also, leakage of the fluid onto other objects and surfaces can cause further damage and accidents. Particular problems are encountered with glass bottles containing wine, and in particular red wine, which can easily cause stains.
This problem has been addressed in two main ways in the past. Firstly, the drips of fluid which are formed when pouring is terminated can be stopped from running down the exterior of the container. These prior art devices often comprise an absorbent material and are attached to or around the container hear the outlet. For example, it is common to use an absorbent ring placed around the neck of a wine bottle to soak up drops of wine as they run down the bottle. However, these solutions merely address the results, rather than the cause, of the drips of fluid.
Secondly, there have been attempts at preventing the formation of the drops of fluid. The first general approach in this area is to install some sort of funnel shaped outlet into the liquid container. The funnel shaped outlet often has an edge or rim which helps to quickly terminate the flow of liquid when pouring is stopped. However, this solution adds to the cost of the container as it involves both an additional component and an additional process step to successfully incorporate the funnel shaped member into the container. Furthermore, there is strong consumer resistance to the use of such an outlet in many areas, such as in wine bottles.
An alternative solution is the provision of a separate device for insertion into the outlet of a liquid container which again serves to prevent the formation of drops when pouring of the liquid is stopped. A commercially available device is described in EP 0 560 777. The device inEP 0 560 777 comprises a circular disc of elastic material which may be rolled up and inserted into the open neck of a wine bottle. The elastic nature of the material causes the disc to expand and grip the interior surface of the neck of the bottle.EP 0 560 777 indicates that the sharp edge of the rolled up disc serves to prevent the fonnation of drops upon termination of pouring.
Similar devices are disclosed inWO 95/19917,CA 2 347 311,US5 979 718, andFR 1 9198 362. All of these documents disclose devices for preventing drip formation which comprise a piece of planar elastic material of various shapes and configurations which may be rolled up and inserted into the open neck of a wine bottle or other container. However, each of these devices have various disadvantages such as a tendency to be pushed inside the wine bottle. Also, the small devices are easily lost and must also be cleaned after each time that they are used.
US 5,924,739 discloses a capsule circumferentially surround the neck of a wine bottle, which has an information panel on its inner side.
There exists a need therefore for a convenient and effective solution to the problem of unwanted drip formation when pouring a fluid from a container.

Turning toFigure 1, a wine bottle is shown generally at 10, which is sealed with a cork. The cork and theneck 12 of thebottle 10 are covered with a unitary piece ofpackaging 14 otherwise known as a capsule. The capsule provides a hygienic seal to prevent contamination of thebottle 10 and its contents. It also serves a number of other functions such as providing indicia regarding the contents of thebottle 10, and, where appropriate, information concerning the payment of excise duty. Also,capsule 14 provides a tamper evident seal so that consumers are confident that the contents of thebottle 10 are genuine and untainted. Thecapsule 14 is made from PVC and is heat-shrunk onto thebottle 10. The capsule may also be made from other plastics such as PET. The capsules may also be made from various metal foils such as tin or aluminium. Such metal foils may also be laminated or coated with plastic material, including plastic-aluminium laminates using, for example, PVC or PET. Metal-containing capsules are typically attached to wine bottles in a rolling step, rather than by heat-shrinking.
Figure 2 shows theneck 12 of thebottle 10 in more detail. Thecapsule 14 comprises a single heat-shrunk piece of PVC which covers the opening of theneck 12 and the cork contained therein. Thecapsule 14 extends down theneck 12 of thebottle 10. The capsule may be considered to comprise two portions; firstly, a substantiallycylindrical portion 16 around theneck 12; and secondly, a bowl-shapedend cap portion 18 covering the cork.
Atear strip 20 is provided which extends coaxially with theneck 12 from the lower edge of thecapsule 14 towards theend cap 18. Asecond tear strip 22 is provided around the circumference of theneck 12 at the upper end of thefirst tear strip 20 at a location relatively close to the top of thebottle 10. Thesecond tear strip 22 divides thecylindrical portion 16 of the capsule from theend cap portion 18.
In use, a consumer would pull thefirst tear strip 20 upwards to form a slit in thelower portion 16 of the capsule. Thesecond tear strip 22 would then be pulled around the circumference of the neck, thus severing theend cap 18 from thelower portion 16 of thecapsule 14. This would have two results. Firstly, thecapsule 14 would be completely removed from thebottle 10 thus exposing the cork ready for removal. Secondly, thelower portion 16 of thecapsule 14 would be ready to use in the formation of a drip prevention device as described below.
Figure 3 shows the configuration of thelower portion 16 of thecapsule 14 immediately after removal from thebottle 10. Theportion 16 assumes a generally cylindrical configuration with an axially extending gap caused by the removal of thetear strip 20. Theportion 16 may be radially compressed into a spiral configuration as shown inFigure 4. The diameter of the compressed configuration of theportion 16 is less than that of the internal diameter of theopen neck 12 of thewine bottle 10.
Turning toFigure 5, the compressedportion 16 has been inserted into the open neck oroutlet 24 of thewine bottle 10 and then allowed to radially expand. The resilient nature of theportion 16 forces it to expand radially to abut the interior surface of theneck 24. The consumer may then pour the contents of thebottle 10 out of theneck 24 via themember 16. The nature of the material of themember 16 and its sharp terminal edge forms a spout which ensures that drop formation upon termination of pouring is minimized. When the bottle is tilted upright to terminate pouring, the rolled spout formed by theportion 16 causes the flow of wine to stop quickly. This abrupt termination in flow minimizes or prevents the formation of drops which would otherwise run down the outside of thebottle 10.
Although the above embodiment has been described with reference to a capsule which incorporates tear strips, the present invention is also applicable to other methods of defining the portion of the capsule to be used as a pouring spout.Figure 6 shows the top of awine bottle 30 having aneck 32. Theneck 32 on thebottle 30 is sealed by a plastic laminated aluminium (polylam)capsule 34. In a similar way to the capsule shown inFigure 2 above, thecapsule 34 is divided into a lower substantiallycylindrical portion 36 and an upper inverted bowl shapedportion 38 covering the cork. In place of the tear strips discussed above, theportions 36 and 38 of thecapsule 34 are divided and defined by a first vertical line ofperforations 40 meeting an upper circumferential circle ofperforations 42. The perforations define predetermined lines of weakness in thecapsule 34. A consumer may easily tear along the vertical row ofperforations 40 and then around theneck 32 of thebottle 30 using the circle ofperforations 42. This will result in the bowl-shapedcap 38 and the rolledrectangular portion 36 of thecapsule 34 being separated from each other and from theneck 32 of thebottle 30. The cork may then be removed from thebottle 30 in the normal way.
Figure 7 shows thelower portion 36 of thecapsule 34 after being removed from thebottle 30. Because of the springy nature of the polylam material,the.portion 36 retains a substantially tubular shape. However, as described above and shown inFigures 4 and 5, thelower portion 36 may be spirally compressed, inserted into the open neck of thewine bottle 30 and then released. Theportion 36 will then expand to grip the inner surface of the open neck of thebottle 30 and will act as a drip preventing pouring spout when the wine is poured from thebottle 30.
Figure 8 shows the top of awine 50 with some features shown in phantom. Thebottle 50 has aneck 52 which is sealed by aPVC capsule 54. Thecapsule 54 is provided with three tear strips. Afirst tear strip 62 extends from the lower edge of thecapsule 54 upwards in a spiral configuration towards the top of thewine bottle 50. In a similar way to the embodiments described above, thetear strip 62 extends upwards to meet a circumferentialthird tear strip 66 around the upper part of theneck 52 of thebottle 50. Thefirst tear strip 62 extends less than 180° around the circumference of theneck 52. Asecond tear strip 64 extends upwardly from the lower edge of thecapsule 54 to meet the thirdcircular tear strip 66. Again, thesecond tear strip 64 extends less than 180° around theneck 52. The lower ends of the first and second tear strips 62 and 64 do not meet but are spaced apart on the lower edge of thecapsule 54.
Thus, when the first, second, and third tear strips 62, 64 and 66 are removed by the consumer thecapsule 54 is divided into three pieces. Firstly, there is theend cap piece 60 covering the cork. Secondly, a substantiallytriangular portion 56 and a trapezoid shapedportion 58 are obtained.
A plan view of the trapezoid shapedportion 58 in a flattened configuration is shown inFigure 9. Theportion 58 may be wound up in a spiral configuration and then inserted into the open neck of thewine bottle 60, with the wider edge (which was defined by the third tear strip 66) inserted into the bottle. The resulting situation (with the rolled upportion 58 inserted into the neck of the wine bottle 50) is shown inFigure 10. Theportion 58 thus defines a pouring spout which minimizes the formation of drops upon termination on pouring wine.
It is evident to a person skilled in the art that there are a number of possible configurations in which a capsule or other packaging may be divided in order to give a suitable portion to use as a drip preventing spout to be inserted into the container.Figure 11 shows the top of awine bottle 70 having aneck 72 sealed by acapsule 74. Asingle tear strip 76 extends in an arc upwards from the lower edge of thecapsule 74 to an apex below the top of thebottle 70, and then curves back down again to meet the lower edge of thecapsule 74 further around theneck 72 of thebottle 70.
Thetear strip 76 extends around about 270° about the circumference of theneck 72. Thetear strip 76 divides and defines two separate portions of thecapsule 74, namely alower portion 78 and anupper portion 80. When the tear strip is removed, theupper portion 80 may be removed to expose the cork in theneck 72 of thebottle 70. Thelower portion 78 is shown in a flattened configuration inFigure 12 having a substantially parabolic shape. In a similar way to the embodiments described above, theportion 78 may be rolled up and inserted into theopen neck 72 of thebottle 70 to define a drip-preventing pouring spout, as shown inFigure 13.
In some instances it may be preferable to avoid the use of the potentially unclean outer surface of the capsule when pouring the contents of a container.Figure 14 shows an alternative embodiment which addresses this point. The top of awine bottle 80 is shown having aneck 82 sealed by acapsule 84. In this case, thecapsule 84 is manufactured from a laminated material having a lower aluminium layer and an upper plastic layer. Thecapsule 84 is divided into a lower substantiallyrectangular portion 86 in an upper cap-like portion 88 by an upwardly extendingfirst tear strip 90 and an upper circumferentialsecond tear strip 92. This is similar to the situation shown inFigure 2. Removal of the tear strips 90 and 92 allows thecap portion 88 to be removed from the bottle and provides thelower portion 86 ready for use as a pouring spout.
Figure 15 shows thelower portion 86 of thecapsule 84 after removal from thebottle 80. Theouter plastic layer 92 may be peeled away to reveal thelower metal layer 94. After the removal of theplastic layer 92, the remainingmetal layer 94 may be rolled up and inserted into theneck 82 of thebottle 80 for use as a pouring spout in a similar way to that described above. Multilayed plastic materials (i.e. without metal layers) could also be used in a similar way.
Figure 16 shows a further embodiment of the invention. Awine bottle 100 is shown having aneck 102 sealed by acapsule 104. Thecapsule 104 is divided into a lower substantiallyrectangular portion 106 and an upper cap likeportion 108 by a first upwardly extendingtear strip 110 and an uppercircumferential tear strip 112.
Figure 17 shows the underside oflower portion 106 of thecapsule 104 after removal from theneck 102. Again, thecapsule 104 comprises a layered material, in this case comprising an upper layer of a first plastic material and a lower layer of a second plastic material. Also, in this case the lower layer has a specific shape rather than merely being a planar multi-layered sheet of material. Theouter layer 114 has a substantially rectangular shape. However, theinner layer 116 has a pre-defined semi-circular shape. Theupper layer 114 may be peeled away from theinner layer 116, which may then be rolled up and inserted into theneck 102 of thewine bottle 100 to form a drip preventing pouring spout as shown inFigure 18.
It is evident to a person skilled in the art that there are numerous techniques which may be used to pre-define the portion of the capsule or other packaging material to be used as a pouring spout. For example, tear strips, and perforations, and other pre-defined lines of weakness may be formed in the capsule or other packaging.
Figure 19 shows the top of awine bottle 120 having aneck 122 sealed by acapsule 124. Again, thecapsule 124 is divided into a lowercylindrical portion 126 and an upper cap-like portion 128. Theportions 126 and 128 are defined by two pre-defined lines of weakness in thecapsule 124 formed by scores in the surface of the material. There is a first upwardly extendingline 130 extending from the lower edge of thecapsule 124 upwards towards the top of theneck 122. Thefirst line 130 terminates at an upper circumferential line ofweakness 132 formed near the top of theneck 122. A notch 134 is defined at the lower edge of theline 130 for ease of use. A consumer may tear thecapsule 124 along the first and second lines ofweakness 130 and 132 to form and remove thelower portion 126 and theupper portion 128 of thecapsule 124 from theneck 122.
Figure 20 shows the substantially rectangular shape of thelower portion 126 in a flattened configuration, after being removed from theneck 122 of thebottle 120. As described above, thelower portion 126 may then be rolled up and inserted into theopen neck 122 of thebottle 120 to form a drip preventing pouring spout.
Figure 21 shows the top of awine bottle 140 having aneck 142 sealed by aPVC capsule 144. Thecapsule 144 is divided into two portions by a line ofperforations 150. The line ofperforations 150 has a lower pair of substantiallyvertical lines 152 and anupper ring 154. The perforations extend from the lower edge ofcapsule 144 upwards towards the top of thebottle 140. As the perforations near the top of the bottle, they turn to define a ring extending most of the way around theneck 152 and then extend downwards to reach the bottom edge of thecapsule 144.
Theperforations 150 thus divide the capsule into a lower substantiallycylindrical portion 146 and an upper cap-like portion 148 (having a downwardly extending tab 154). Thetab 154 is defined by the portion of thecapsule 144 between the lower lines ofperforations 152.
A user may grasp thetab 154 and pull upwards, tearing the capsule along theperforations 150.
Theportion 146 of thecapsule 146 is then freed from thebottle 140 ready for use as a pouring spout.Figure 22 shows the general shape of 146 of a rectangle with rounded corners. Theportion 146 may be rolled up and inserted into theneck 152 of thebottle 150 in a similar way to that described above.
An important aspect of the invention relates to the provision of indicia on the packaging, and in particular on the portion of the packaging that is adapted to form a spout. For example, the spout portion may be provided with promotional information either relating to the product itself or to a different product, service or offer etc. Preferably, the spout portion contains information about special offers relating to the product. More preferably, the spout portion forms a voucher which is redeemable at stores. Also, the indicia could comprise information in machine readable form, such as a bar code. The indicia could be provided on the external and/or the internal surface of the packaging, for example, it may be desired to provide indicia on the internal surface of the packaging to prevent it from being viewed before the product is purchased.
Although the invention has been described with reference to bottle having corks, it is also applicable to other types of sealed container, such as screw top bottles. As described above, the packaging could extend over the top of the bottle, covering the screw top. Alternatively, the packaging could extend over the lower potion of the screw top, leaving the top of the screw top uncovered. Also, the portion of the packaging to be used as a pouring spout could be removed as a result of the top being unscrewed from the bottle. Alternatively, the packaging could be adapted to be broken by the consumer as a separate step to the unscrewing of the screw top.
