Definitions
- Beverage container having means for foam generation
- This specification relates to the production of foam for beverages.
- the specification is particularly, but not exclusively, concerned with the production of a head of foam on beer dispensed from relatively small containers such as cans, bottles and the like.
- a secondary chamber in the form of a plastic insert which is pushed down inside a can.
- the chamber is provided with an orifice which communicates permanently with the main body. After sealing the can, beverage enters the insert to compress the gas therein, which is normally nitrogen. It is stated that subsequent ejection of gas and/or beverage causes the formation of a head.
- the insert is in the form of a plastic moulding.
- WO-A-91/07326 there is disclosed a secondary chamber in the form of a plastic insert which is pre- charged with nitrogen under pressure.
- the insert has a valve whose properties are altered after filling of the can with beverage and sealing, so that the valve will open when subsequently exposed to the pressure differential when the can is opened. This may be achieved by heating the insert, e.g. during pasteurization of the beer.
- a container of beverage sealed under pressure the container being provided with a secondary chamber in the form of a hollow insert adapted to provide a flow of gas through an orifice into the beverage when the container is opened, wherein the insert is in the form of an elongate tubular member whose axis extends around an axis corresponding generally to the axis of the container.
- the insert will be curved in the form of a part annulus, although the ends could meet to form a complete annulus.
- the axis of the insert will follow a curved path.
- the insert need not follow a strictly circular or arcuate path.
- the insert will generally lie in a plane perpendicular to the axis of the container, although a helical form would be possible. In general the insert will lie against, and extend around, the cylindrical wall of a can or bottle.
- the insert is preferably resilient, so that it exerts an outward force against the container wall. This serves at least partly to keep the insert in position.
- the insert is preferably provided at the base of the container.
- a flexible, resilient insert is formed in a substantially straight condition - although it may be wound up on a relatively large diameter reel. The insert will then be bent into a curved configuration and placed in the container.
- a flexible resilient insert could have an initially curved configuration and then either straightened out or bent even more to assist in insertion, after which it will revert to its initial configuration wholly or partly.
- the insert is in the form of an elongate tube sealed at both ends, having a diameter which is several times less than its length. Its length may be of the same order of the internal circumference of the container, and preferably somewhat less, in which case the insert will extend round a major part of the internal circumference of the container. It could be longer and adopt a helical form.
- the arrangement is preferably such that resilience of the insert presses it against the container wall to keep it in position. However, this may not always be sufficient to locate the insert with the required level of security, particularly if the container is subjected to rough handling during transportation.
- a can is provided with an inwardly directed ridge spaced from its base, and the insert is located between the ridge and the base.
- a locating sleeve is provided. This is in the form of a ring or the like which is pressed down the can, on top of the insert. The sleeve engages the wall of the can resiliently over a sufficient surface area to provide the required locating force.
- the sleeve is preferably in the form of a circular ring which may be deformed into an oval to assist insertion into the can, and then springs back to its original shape.
- the insert may be provided with a series of circumferentially extending ribs, spaced along its length, which will assist in permitting bending whilst providing strengthening to resist compression when the container is pressurised.
- the insert may be in the form of a corrugated tube, e.g. of a "concertina" type.
- the interior profile may assist in foam generation, possibly by creating turbulence within the insert which creates foam which is ejected. Spaces between the corrugations will also assist beer to fill the container properly with the insert in position.
- the insert may be of any desired cross section, although a circular cross section may be simplest. It may be of elliptical cross section, or shaped to match the interior profile of the bottom of the can, for example. It need not have a regular cross section along its length.
- the insert may be of any desired length, in accordance with the intended use.
- the insert is preferably made by a continuous extrusion process of a type already known per se for tubes and sachets used in other applications. Alternatively a blow moulding process could be used.
- the ends of the insert could be sealed by plugs, or by mechanical crimping and/or heat sealing. The latter could be carried out either during or after the extrusion of moulding process.
- an insert curved round against the wall of a container means that the central region at the base of the container is free.
- the insert mainly occupies the central region of the contai er. This can cause difficulties when filling the container with beer.
- an insert which extends around the periphery of the can such problems are reduced.
- the insert should contain an "inert" gas such as carbon dioxide and/or nitrogen, this can be achieved in a known way by e.g. flushing with nitrogen whilst in the container.
- an elongate insert made from a continuous process enables the gas to be provided at the forming stage in a relatively easy manner.
- the insert can be made as a single item as opposed to complicated two piece mouldings which have been used previously.
- a tube is continuously extruded. It is subjected to internal pressurisation using nitrogen, pushing it outwardly into a mould which forms the corrugations in a manner known from the production of flexible hoses and electrical conduits. Suction may also be employed.
- the tube is heated and pressure sealed at intervals by the configuration of the mould to define a string of inserts, and this string is wound on a reel.
- the tube could be sealed at intervals downstream from the moulding system.
- the string may be 1000 m or more in length.
- the reel is supplied to a canning plant, where the string is unwound and the inserts separated from each other, as necessary.
- One or more orifices can be formed at the time of forming the insert, or just prior to insertion or even after insertion.
- the orifice could be used as in prior art systems, for example forming a permanent communication between the insert and the beverage as in GB-A-2,183, 592; being provided with a temporary sealant such as gelatine as in GB-A-1,266, 351; or being provided with a valve which only opens when the container is opened as in WO-A-91/07326. Such a valve could be e.g. pressed into the insert.
- the orifice is in the form of a slit, extending a small distance around the circumferences of the tube, it can be arranged to be closed under the resilience of the material when the tube is straight, but to open if the tube is bent into a curve with the slit on the outside of the curve.
- an invention disclosed herein consists of a method of manufacturing an insert for use in a container of beverage sealed under pressure, the insert being adapted to provide a flow of gas into the beverage in the container when the container is opened, so as to promote the formation of foam; wherein a continuous tube is formed, the tube is provided with an inert gas atmosphere, and sealed at intervals to define a plurality of elongate gas filled inserts, and when desired the inserts are separated from each other.
- an invention disclosed herein provides apparatus for manufacturing an insert for use in a container of beverage sealed under pressure, the insert being adapted to provide a flow of gas into the beverage in the container when the container is opened, so as to promote the formation of foam, the apparatus comprising means for extruding a plastics tube, a mandrel over which the tube passes into a moving mould having a corrugated profile, means connected to a source o-f inert gas for blowing the inert gas into the tube in the mould, and means for sealing the gas filled tube into a plurality of elongate tubular inserts.
- the invention also extends to a insert made by a method or apparatus as set forth above.
- an invention disclosed herein consists of an insert for use in a container of beverage sealed under pressure, the insert being adapted to provide a flow of gas into the beverage in the container when the container is opened, so as to promote the formation of foam, wherein the insert is in the form of an elongate, hollow tube of food grade material, the tube being sealed at both ends and provided with a restricted orifice intermediate its ends, the insert being filled with an inert gas, and being sufficiently rigid to resist collapse when subjected to a pressure difference of 2 bar between its exterior and interior.
- the degree of rigidity is necessary to ensure that pressurisation causes desired effects rather than collapse of the insert and expulsion of the fluid it contains.
- the tube may be of plastics such as food grade HDPP (high density polypropylene) or of another suitable material such as aluminium.
- HDPP high density polypropylene
- aluminium an advantage of aluminium is that if used in an aluminium can, it facilitates recycling.
- tubular or other inserts which can be made by continuous processes such as extrusion, is that it is a simple matter to provide inserts of different forms and volumes. For example varying the length between the seals will vary the volume of the inserts. It is relatively easy and inexpensive to change an extrusion die to produce inserts with different cross sections and diameters. The position of the orifice is easily variable, by moving it up or down, to alter the performance. These factors make it easier to cope with different products - e.g. beer, stout or lager - and different serving temperatures.
- the insert could be provided with a valve arrangement.
- the orifice provides a permanent communication between the secondary chamber and the main body of beverage.
- liquid beverage enters the insert and compresses the gas therein.
- the container is opened and the pressure drops to atmospheric, the liquid is ejected.
- the gas has returned to its original atmospheric pressure and there is no driving force to eject it.
- inert gas refers to such gases and any other suitable gases which will not taint beer.
- the insert is therefore provided with the orifice at a position such that there will be, below the level of the orifice, a substantial volume in which beverage will be trapped.
- the insert initially contains gas at atmospheric pressure and is in permanent communication with the body of the container.
- the container is filled with beverage which will usually be at a temperature lower than a normal dispensing temperature and typically close to 0°C.
- the beverage is supersaturated with gas, containing carbon dioxide and nitrogen.
- the nitrogen may be obtained at least in part by dosing the can with liquid nitrogen. Additionally or alternatively the beverage may be pre-nitrogenated.
- the container is sealed and the pressure inside rises as a result of evolution of the gas from the beverage and the liquid nitrogen dosing if applicable.
- the beverage will thus enter the insert through the orifice to compress the gas therein.
- the orifice is spaced from the bottom of the insert by a distance sufficient to define below the orifice a substantial reservoir.
- the orifice is positioned such that the liquid beverage entering the insert will fill the reservoir and cover the opening. Gas will then be trapped and compressed above the beverage in the insert.
- the gas in the insert When the container is vented to atmosphere, the gas in the insert first expels liquid beverage through the orifice, until the level drops to uncover the orifice. At this point the gas is still under significant pressure because the free volume of the insert is reduced by the volume of liquid trapped in the reservoir below the level of the orifice. Thus, the original mass of gas in the insert occupies a smaller volume.
- the gas is ejected through the orifice until its pressure drops to atmospheric. In a simple case, the volume ejected (at atmospheric pressure) will be approximately equal to the volume of trapped beverage in the reservoir.
- the liquid beverage itself does not initiate significant bubble formation to an extent sufficient to generate a head.
- the jet of gas which is ejected subsequently causes the bubble formation.
- the arrangement may be such that a relatively small quantity of liquid is above the orifice before the container is opened, so that it is disposed of rapidly before the gas is ejected. With such an arrangement, there may be an additional initial effect in which some gas forces its way through the layer of liquid above the orifice, as soon as the container is opened. This may cause foam to be ejected, and give rise to bubble initiation in the beverage in the container even before the main quantity of gas is ejected through the orifice.
- the gas is subsequently ejected through the orifice, it passes over the trapped liquid in the reservoir. This may lead to some foam being ejected through the orifice together with the main body of gas.
- a simple orifice is provided in the tubular insert at a position between the top and bottom extremities.
- the orifice is preferably on the side which will point inwardly to the centre of the container.
- the orifice may be provided by drilling, laser boring, punching or as part of the initial forming process.
- the orifice is preferably positioned such that between 25% and 75% of the volume of the chamber is below the level of the orifice. A preferred value is around 50%.
- a preferred size is about 14 ml to 16 ml, which is appropriate for a number of sizes including 440 ml and 500 ml containers.
- the size of the orifice may affect the performance.
- the orifice may be circular with a diameter of say 0.1 to 0.5 mm, a preferred size being about 0.3 mm.
- the length of the orifice i.e. from the interior of the secondary chamber to the main body of beverage, may also be significant. Too long a passage may result in dissipation of energy.
- the orifice will have a length in the range of 0.25 to 1 mm, a preferred value being about 0.5 mm. The length will usually be governed by the thickness of material used but this can be modified locally in the region of the orifice. Steps may be taken to prevent air entering the insert once it has been filled with gas and the orifice formed. This may be achieved by e.g.
- Filling of the container with beverage will generally be carried out at a temperature close to 0"C, a typical range being 1-5°C.
- a typical serving temperature may be in the range of 7-10°C.
- consumers may refrigerate beers further and serve them at temperatures of say 4-5°C. Even so, pressure in the can will be substantially above that at the time immediately prior to sealing, due to evolution of gas, and nitrogen dosing.
- beer used may have C0 2 at say 1: 1.2. It may be desirable to have a high level of nitrogenation, at say 60-70 ppm.
- the initial pressure inside the insert is 1 bar (absolute) . After sealing the pressure inside the container - and thus the insert - rises to about 3 bar and then rises still further with temperature increase.
- the mass of gas which is trapped in the insert is approximately that which occupies the volume of the insert at atmospheric pressure. This is compressed when liquid beverage enters the insert and it is the energy stored in this mass of gas which provides the driving force for foam creation. It has been found that it is advantageous to increase this mass and that this can be done without increasing the volume of the insert.
- the container is provided with an insert towards its base, filled with beverage whilst still leaving a headspace, and sealed.
- a certain volume of liquid beverage enters the insert through the orifice, and compresses the gas therein in the manner described earlier.
- the container is inverted so that the orifice in the insert is in communication with the gas which forms the headspace in the container.
- the insert contains a volume of liquid beverage and a volume of gas, at equilibrium with the headspace gas.
- the temperature of the inverted container is then raised it has been found that an improved effect is obtained when the container is cooled, placed the right way up, and opened.
- the insert Accordingly the volume within the insert will be occupied by a greater mass of gas.
- the insert contains a greater mass of gas than it did previously. When the can is inverted, it is this increased mass which is trapped, thus improving performance.
- the pressure inside the insert is the same as before invention and heating, but the mass of gas has increased.
- Insertion and heating of the container can be carried out in a convenient manner using conventional pasteurisation techniques.
- pasteurisation the container is heated to 63 °C and then cooled. If the container is inverted, pasteurised, and then cooled and turned the right way up again, the improved effect will have been gained.
- a method of manufacturing a sealed container of beverage under pressure including means to promote the formation of foam by the ejection of a stream of gas from a chamber when the container is opened, comprising the steps of:-
- the arrangement is such that beverage in the chamber covers the orifice, when the container is the right way up, both before and after the heating step.
- the arrangement is such that the orifice of the chamber is in communication with the headspace gas when the container is inverted.

- Figures 14(a) and 14(b) show stages after opening the can.
- Figure 15 shows the can in an inverted condition for pasteurisation.
- the insert 1 shown in Figures 1 and 2 is in the form of an extruded tube of food grade HDPP. It has sealed regions 2 at either end where it is joined to other inserts, a plain middle region 3, and corrugated portions 4.
- the middle region 3 will be provided with an orifice 5 at a later stage, in its side.
- the insert is run in the form of an elongate, hollow, resilient tube which, once separated from the other inserts, can be bent to a desired configuration.
- the inserts are made by an extrusion technique.
- Plastics material 6 flows from an extruder over a mandrel to form a continuous tube. This passes into a chain of moving semi-cylindrical mould blocks 8.
- the top and bottom blocks co-operate to define a corrugated tube 9 which will form the inserts.
- the blocks are configured to provide the central region 3 for each insert, and a region 10 which will form the end regions 2 of the inserts.
- the blocks are moved along by a conveying system 11.
- a source of nitrogen is connected to a tube 12 which passes through the mandrel 7 into the tube 9. This pumps nitrogen at about atmospheric pressure through an orifice 13 to push the tube into the mould blocks 8. Suction may be provided also.
- the blocks pass through a cooling sleeve 14, to solidify the tube properly.
- the tube After leaving the moulding phase, the tube passes to a sealing station where punches 15 - which may be heated - act upon the region 10 to define the end 2 of an insert and seal it.

- This series may be wound up on a drum for future use.
- the inserts are to be placed in a can of beer just prior to the can being filled.
- FIG 4 shows one stage in the preparation for this.
- An insert 1 is presented to a station where there is a receiving sleeve 16 and a cutter 17.
- the cutter severs the sealed region joining the insert 1 to the next insert, so that the insert is now free but is still fully sealed.
- a plunger 18 then pushes the insert laterally through an aperture 19 into the sleeve 16.
- the plunger 18 has a piercing point 20 which forms the orifice 5 as this is being done.
- the orifice 5 is about half way up the insert.
- Figure 5a shows the insert 1 within the sleeve 16. It will be noted that the ends 2 are projecting, which would make insertion in a can difficult. Accordingly, disposed around sleeve 16 for relative rotation is a sleeve 21. Rotation of this wipes the ends of the insert round, as shown in Figure 5b.
- FIG. 6 illustrates a stage of insertion into a can 22.
- the insert 1 is within sleeves 16 and 21, and a piston 23 is also provided.
- the sleeves and piston are activated in an appropriate order to leave the insert at the bottom of the can. This is shown in Figure 7.
- the sleeves hold the insert in a compressed condition.
- the arrangement is such that the sleeves containing the insert may pass through a restricted opening into the can. As shown, the sleeves fit closely within the can. In some arrangements where the opening diameter is much smaller than the main can diameter, the sleeves will be spaced a greater distance from the can wall.
- the insert 1 springs out under its own resilience to engage the wall of the can 22, extending around the wall. It lies on the base of the can and has the form of a part annulus whose centre line is curved around the longitudinal axis of the can. The plane of the annulus is perpendicular to the axis of the can.
- the orifice 5 is directed inwardly to the centre of the can. Depending upon the length of the insert, it may form almost a complete annulus or may form e.g. a horseshoe shape.
- Figures 8 and 9 show a retaining sleeve 24 to assist in keeping the insert down at the base of the can.
- the sleeve is in the form of a resilient ring of food grade HDPP. It has castellations 25 around its top and bottom, and a plurality of inwardly projecting tabs 26 around the inside.
- the ring 24 can be squeezed into e.g. an oval to assist placing in the can.
- the castellations 25 engage the wall of the can so as to resist dislodgement.
- the ring 24 keeps the insert 1 firmly in place.
- Figure 11 shows an alternative method for locating the insert.
- a can 27 is provided with an inwardly directed circumferential ridge 28 under which the insert 1 is retained.
- the location of the insert 1 and locking ring 24 are performed quickly after the insert is pierced. Beer is then added quickly to the can to cover the insert and prevent excessive air (containing oxvgen) getting into the insert.
- the beer contains carbon dioxide and may have been nitrogenated. Additionally or alternatively a portion of liquid nitrogen may be added to the beer, once in the can.
- the can is then sealed and the position is as shown in Figure 12 (where the retaining ring has been omitted) and in Figure 13(a) .
- a headspace 29 of gas is provided above the beer. Filling takes place at a low temperature, say 1-5°C.
