Definitions

  • the invention relates to beverage containers and to methods of dispensing beverages therefrom.
  • it relates to beverage containers for sparkling and semi-sparkling wines and methods of dispensing sparkling and semi-sparkling wines.
  • One way of supplying beverages such as sparkling and semi-sparkling wines to public houses, bars and like establishments for sale by the glass is in traditional bottles of about 1 litre capacity, usually made of glass.
  • a problem with supplying beverages in such bottles whose capacity is larger than the measure in which the product is sold, may arise from the fact that not all of the contents of the bottle may be required to be dispensed at any one time. Once the beverage has been exposed to the atmosphere the quality of the product may deteriorate quite rapidly, even if the bottle is resealed.
  • SUBSTITUTESHEET under pressure, since, unless the bag is completely full, it can inflate as a result of C0 2 released from the beverage with resulting loss of effervescence and deterioration of quality.
  • Beverages such as beer and lager are often stored in kegs in direct contact with pressurised carbon dioxide gas and dispensed by means of the carbon dioxide gas pressure.
  • contact with carbon dioxide gas adversely affects the character and quality of many beverages, such as still beverages in general, sparkling, semi-sparkling, and still wines, and also some other carbonated beverages such as naturally sparkling mineral waters.
  • increased carbonation may also contravene customs regulations and result in a higher customs duty becoming payable.
  • Traditional kegs are also supplied to establishments on a returnable basis, and this is not well suited to wine distribution channels which are set up to supply wine in disposable containers. Any change in this respect is generally resisted.
  • the present invention provides a disposable beverage container comprising a substantially rigid bottle made of an impermeable lightweight plastics material, a lightweight impermeable flexible bag for containing a beverage to be dispensed located within said bottle, the bottle having inlet means for operatively connecting in use the region defined between the flexible bag and the walls of the bottle to a source of pressurised fluid, and outlet means communicating with the interior of the flexible bag through which in use beverage can be forced from the bag under the pressure -resulting from the pressurised fluid in said region between the bag and the bottle walls.
  • a beverage container is suitable for the storage and dispense of a wide range of beverages, but is particularly well suited to the storage and dispense of sparkling and semi-sparkling wines and indeed wines in general.
  • beverage is forced out under positive pressure which means that inflation of the bag in the case of sparkling beverages does not occur.
  • beverage in the bag becomes exposed in practice to air let into the bag via the beverage outlet valve or tap after a number of dispenses, with the result that the quality of even still wine deteriorates in time. This may be avoided in accordance with the invention by the contents being at greater than atmospheric pressure and so preventing the ingress of air.
  • the pressurised fluid which acts as a propellant to dispense the beverage from the flexible bag is confined to the region of the bottle around the outside of the bag and does not contact the beverage.
  • the pressurised fluid may be any fluid, for example air, carbon dioxide or mains -water, without a risk of the beverage becoming contaminated or having its character altered.
  • carbon dioxide there is no possibility of increased carbonation in contravention of customs regulations.
  • the problems associated with dispense of wines and the like from traditional wine bottles for sale by the glass are also avoided.
  • the beverage container is lightweight, inexpensive to produce and disposable which is advantageous for supplying beverages to public houses and the like.
  • Public houses tend to be at diverse locations and there is a resistance in the wine distribution industry to change to containers such as traditional beer kegs whose cost would lead to collection and return for refilling being an economic requirement.
  • the lightweight nature of the container further facilitates its use as a bulk container holding tens of litres whilst still being relatively manageable and easy to handle.
  • the bottle is preferably made of a lightweight substantially rigid impermeable plastics material such as P.E.T.
  • a lightweight blown P.E.T. bottle having very thin P ⁇ E.T walls is used.
  • the material can be transparent or opaque.
  • the bottle can have any suitable shape capable of withstanding a sufficient internal pressure.
  • the bottle could be spherical or ovate.
  • the bottle is a cylinder closed by hemispherical end portions. Such is a particularly convenient shape which is well adapted to withstand internal pressure.
  • the impermeable flexible bag may be made of any sufficiently strong lightweight impermeable flexible material.
  • the bag is made of a laminate of plastic films or plastic films and metal foil and is of the type used in conventional bag in box containers. In one embodiment a laminate of plastic films is coated with metal.
  • the bag should preferably be of a size and shape such that when it is filled with a beverage it expands to substantially fill the bottle.
  • the bag is preferably secured to the bottle, in the region where the outlet means communicates with the bag, and arranged such that pressurised fluid between the walls of the bottle and the bag can exert pressure against substantially the entire outer surface of the bag to force the beverage from within.
  • the bag is secured to the bottle at a neck thereof on an axis of symmetry of the bottle.
  • the inlet means may have any convenient form, for example a self-sealing or sealable connector which allows the bottle to be sealed e.g. between uses or for transport.
  • the inlet means preferably comprises a non-sealing connector connectable to a source of pressurised fluid through which in use pressurised fluid can be admitted into the region of the bottle around the outside of the bag.
  • a non-sealing connector connectable to a source of pressurised fluid through which in use pressurised fluid can be admitted into the region of the bottle around the outside of the bag.
  • the container is depressurised to atmospheric pressure and can be disposed of safely. This avoids a problem associated with traditional kegs which typically remain pressurised after the beverage has been dispensed and could be hazardous if not returned to the supplier.
  • a one-way valve may be associated with the source of pressurised fluid.
  • the outlet means preferably includes an elongate dip tube extending into the bag.
  • the tube is preferably open-sided or is perforated at a plurality of points along its length.
  • the tube is flexible so that it can adapt to the shape of the collapsing bag.
  • the outlet means preferably includes a resealable two-way outlet valve through which the bag can be filled initially, resealed, and through which beverage can then be dispensed in use.
  • Such an outlet valve may be mounted to the bottle and in one embodiment an outlet valve and inlet connecto ⁇ : are combined into a single unit which is mounted to the bottle.
  • such a combined unit which also carries both the dip tube and the flexible bag is secured to the neck of the bottle along the central axis thereof.
  • an outlet valve is arranged to be opened on connection to a dispense head and closed on disconnection therefrom.
  • the plastic bottle itself may be sufficiently strong to withstand relatively high internal pressures, it may not be so well adapted to withstand impacts such as may result from rough handling. Further, a bottle shape which is suitable for withstanding an internal pressure may not facilitate ease of handling and storage.
  • the beverage container is further provided with a lightweight outer casing which may cover all or part of the bottle, and which may protect the bottle or facilitate easier handling or storage.
  • the preferred bottle of cylindrical shape and hemispherical ends is provided at its ends with lightweight hollow plastic end cups, which are secured to the bottle for example by adhesive and protect the bottle from impact and rough handling.
  • the end cups preferably have flat end surfaces which allow the container to be free standing and facilitate stacking of one container on top of another.
  • an internal bottle shape for optimum pressure withstanding is combined, in a simple structure, with an external container shape for ease of handling and storage.
  • an end cup may be provided with a recessed cut away portion within which the connector and/or valve is/are located so that a connector or valve is protected by the end cup and does not protrude beyond the flat surface of the end cup to interfere with stacking.
  • the end cups may be provided with a raised rim to facilitate safe rolling of the container along the ground and the end cups may be provided with cut away hand holds to permit easy handling.
  • the bottle and any end cups are enclosed within a protective sleeve formed of any suitable lightweight material, such as cardboard.
  • the present invention provides a method of dispensing a beverage, the method comprising the steps of providing a disposable beverage container having a substantially rigid bottle made of a lightweight impermeable plastics material and an impermeable flexible bag containing a beverage to be dispensed located within the bottle, operatively- connecting the region defined between the walls of the bottle and the flexible bag to a source of pressurised fluid, dispensing beverage from the bag under the pressure exerted by the pressurised fluid there around, through outlet means communicating with the bag and, once substantially all the beverage has been dispensed from the bag, disposing of said container and continuing said method with a further beverage container.
  • Beverage containers which may have any or all of the features discussed above may be connected in turn to a source of pressurised fluid in a public house or the like for dispense. Each container is disposed of and replaced in turn as substantially all of the beverage contained therein is dispensed.
  • the pressurised fluid may be any fluid since it does not come into contact with the beverage to be dispensed.
  • Pressurised sources of fluid may be used which do not require a mechanical pump to supply the fluid to the bottles, such as pressurised bottles of gas (e.g. C0 2 , air) or mains water supply. Alternatively a pump may be used to pump a fluid, e.g. air, into the bottles.
  • a pressurised source may be _
  • Beverage may be dispensed from each container in turn as required to a dispense head situated on a bar for sale by the glass.
  • the beverage may be passed through a chilling unit on the way to the dispense head.
  • Fig. 1 shows a perspective view of a beverage container according to this embodiment of the invention
  • Fig. 2 shows a schematic sectional view of the beverage container of Fig. 1 in situ in a bar or public house.
  • the illustrated beverage container 1 is lightweight and disposable and comprises a bottle 2, within which is located a flexible bag 3. Both the bottle 2 and the bag 3 are impermeable.
  • the bottle 2 is a blown P.E.T. bottle having very thin walls and is therefore very lightweight. It has a middle cylindrical portion 4 and is closed at either end by hemispherical portions 5,6.
  • the bottle 2 has a neck 7 at its upper end which is closed by a valve unit 8 mounting a connector 9 and valve 10 to the bottle.
  • the illustrated bottle 2 may have a capacity of 10 to 20 litres.
  • Hollow cylindrical end cups 11, 12 made of thin lightweight plastic are glued to the hemispherical end portions 5, 6 of the P.E.T. bottle 2 to protect the bottle and facilitate easy handling and storage.
  • the diameter of the end cups is slightly greater than the diameter of the cylindrical portion 4 of the bottle to provide protection for the bottle 2 when the container 1 is on its side.
  • the end surfaces 13, 14 of the end cups are flat to permit the container 1 to stand upright on surface 14 and to allow stacking of one container on top of another.
  • the top end cup 11 is extended vertically beyond the top of the bottle 2 above the valve unit 8 to protect connector 9 and valve 10 and a cut away recess 15 is provided in the flat top 13 to permit access to the connector and valve. Thus the connector 9 and valve 10 do not interfere with stacking.
  • the end cups 11, 12 are further provided with cut away hand holds 16 in their side walls to facilitate easy handling.
  • the flexible bag 3 is made of a lightweight laminate of plastic films or a laminate of plastic films and metal foil and contains a beverage 17 such as a sparkling or semi sparkling wine. When inflated the bag 3 is of about the same capacity as the bottle 2 and will take up substantially the same shape within the bottle.
  • An elongate open sided flexible dip tube 18 engages as a push fit with valve 10 and extends into the flexible bag 3.
  • the bag 3 is heat welded to a gland (not shown) which is secured around the top of the dip tube 18 such that the bag 3 is firmly secured to the valve unit 8 at the neck 7 of the bottle 2.
  • Connector 9 is non-sealing (i.e. the inlet is always open) and is connected in use via duct 19 to a source of pressurised fluid such as a cylinder of pressurised carbon dioxide or an air pump, so as to pressurise the region around the bag 3 between the walls of the bottle 2 and the bag 3 by admitting pressurised fluid 20 into that region * '
  • the pressurised fluid 20 exerts pressure on the beverage 17 contained within the bag 3. Because pressurised fluid 20 does not mix with beverage 17, any suitable fluid can be used as a pressurised fluid without adversely affecting the character or quality of the beverage or contravening customs regulations.
  • Valve 10 is a re-sealable two-way outlet valve which is connected in use via duct 21 through a chilling unit 22 to a dispense head 23.
  • the valve 10 is opened on engagement with duct 21 and is closed when the duct 21 is disengaged therefrom.
  • Dispense head 23 is located on a bar 24 of a public house and is operated by a tap 25. The remaining apparatus is located under or near the bar.
  • the apparatus is used to dispense beverages such as sparkling and semi-sparkling wines through the dispense head 23 for sale and consumption by the glass.
  • beverages such as sparkling and semi-sparkling wines
  • the tap 25 is opened for dispense
  • beverage 17 contained in the flexible bag 3 is pressure fed through dip tube 18 and duct 21 to the dispense head 23 under pressure from pressurising fluid 20.
  • the beverage 17 is not exposed to the atmosphere until it is dispensed through tap 25.
  • the pressurised fluid 20 will be topped up through inlet means 9 and will act to progressively collapse bag 3 around the flexible dip tube 18.
  • the gland (not shown) at the top of the dip tube 18 may prevent complete collapse of the bag around the dip tube, and because the dip tube 18 is elongate and open sided practically all the beverage 17 can be dispensed without the bag collapsing to completely block the outlet flow path.
  • the ducts 19 and 21 can be disengaged from the valve unit 8.
  • As connector 9 does not seal any excess pressure will be dispersed and the depressurised container 1 can be disposed of safely, since it is made of inexpensive lightweight plastic disposable materials and is no longer pressurised. It is not necessary to undertake the costly and inconvenient process of returning the container 1 to the supplier for refilling.
  • the container 1 can be replaced by a different container l 1 full of beverage and the dispense process can be continued.
  • beverage container and method of dispensing a beverage have been described particularly in relation to sparkling and semi-sparkling wines, it should be clearly understood that the invention can be usefully applied to a very wide range of beverages, including still and carbonated beverages.
