Definitions

  • This invention relates to a pressurised sealed container of carbonated beverage, which, on opening, releases gas bubbles from the liquid and to a method of enhancing release of gas bubbles.
  • the invention has particular application to containers of beer, which is used in this specification in its broad sense to include ales, stouts and lagers, for the enhancement of a foamed head on beer from the opened container.
  • a foamed head on beer is dependent, amongst other things, on the release of sufficient gas from the beer. This can be achieved by dissolving a high quantity of gas under high pressure in the beer to ensure the release of sufficient gas when the beer is poured from the container. With many beers, however, especially cask beers, it is required to provide a low carbonation content to avoid spoiling the taste of the beer. A foamed head can only be produced with such beers by turbulent dispensing of the beer.
  • GB-A-1266351 discloses a complex and potentially expensive arrangement in which a secondary chamber in the container releases carbonated beverage through a narrow orifice into the main chamber of the container to produce excitation and a continuous release of gas for producing a foamed head.
  • GB-B-2183592 discloses the case of an insert which defines the secondary chamber. This arrangement is also potentially expensive and difficult to package.
  • GB-A-158862 discloses excitation of a carbonated beverage after the container has been opened, e.g. by injection of gas or by pouring the beverages over shattered polystyrene granules, which forms a large uneven surface to cause excitation.
  • the present invention seeks to overcome these disadvantages of the prior art and to provide an improved, simple method of enhancing formation of a foamed head on low gas content beer.
  • the invention is, however, applicable to other carbonated beverages, where it is desired to produce release of a stream of gas bubbles on opening of a container, suitably a can, of the beverage. It is possible, for example, that a stream of gas bubbles may be used to produce a predetermined sound, as by blowing a whistle.
  • the present invention provides a method of enhancing release of gas from a carbonated beverage in a sealed container on opening of the container, in which a nucleation promotion agent is provided in the container, the agent being a material capable of carrying entrapped stabilised gas bubbles in contact with the beverage.
  • the invention also resides in a pressurised sealed container of a carbonated beverage having provided in the container a nucleation promotion agent for promoting release of gas bubbles from the beverage when the container is opened, the agent being a material carrying entrapped stabilised gas bubbles in contact with the beverage.
  • the invention may reside in a method of enhancing formation of a foamed head on a carbonated beverage on opening of a pressurised container of the beverage, the method comprising providing in the container nucleation promotion agent in the form of a material capable of carrying entrapped stabilised gas bubbles in contact with the beverage.
  • the invention also resides in a pressurised sealed container of a carbonated beverage capable of producing a foamed head on the beverage when the container is opened, the container being provided with a nucleation promotion agent for promoting release of gas bubbles from the beverage when the container is opened to enhance the formation of a foamed head, the agent being a material carrying entrapped stabilised gas bubbles in contact with the beverage.
  • the material which carries the entrapped stabilised bubbles may be provided as an insert in the container, or may be provided as a coating on the interior of the container.
  • the material is selected to have physical properties of hydrophobicity and porosity effective for entrapping bubbles and readily releasing the bubbles on release of pressure.
  • the surface area and thickness are selected to ensure that a desired volume of gas is entrapped in a releasable manner, sufficient to promote the formation of a stream of bubbles or "gushing", from a carbonated beverage.
  • the material is also selected to ensure non-toxicity and to have little or no effect on the flavour of the beverage .
  • the material may be affixed to the interior of the container with a food grade adhesive, or may be loosely received in the container. However, it is preferably held in place by means of a suitable clip.
  • the material may be in the form of a plain or fluted tube, or a flat or pleated plate, or in the form of a coil.
  • the material may be in the form of a semi ⁇ rigid "honeycomb" made in any suitable way.
  • the honeycomb may be produced by folding a single sheet of material or produced by bonding several plain sheets of material together in appropriate fashion.
  • the material may be in the form of numerous plain hollow tubes ("straws") bonded together in suitable fashion, or as a corrugated structure prepared by bonding a fluted sheet of material to a plain one.
  • the material is conveniently inserted in the container and retained in position by a suitable device, e.g. a clip.
  • a suitable device e.g. a clip.
  • a suitable food-grade plastic for example moulded polyethylene or polypropylene
  • the secondary device is both of appropriate physical and structural properties and of appropriate dimensions it may act to restrain the movement of the material within the container, either by the friction generated between the material and the container wall, or because of the specific spatial interactions between the secondary device and the material on the one hand, and the container on the other.
  • plastics materials have the desired properties, for example, spun polyolefin and polytetrafluoroethylene membranes.
  • Spun-bonded high- density polyethylene fibres in a form such as TYVEK has been found to be particularly effective.

  • Thicker grades of "type 10" TYVEK (for example those with bulk densities of 73 g.m” 2 , 79 g.m” 2 or 85 g.m “2 ) work less well.

  • the can 10 has an insert 18 of a sheet material 17 adapted to carry entrapped stabilised gas bubbles when the container is filled to a suitable level with a carbonated beverage under pressure.
  • the insert is preferably made of TYVEK as discussed herein. This is provided in a corrugated form (see especially Figures 2a_ and 2c) ; the corrugated material 17 can then be bent to provide the material as a generally cylindrical corrugated body adjacent an inner surface of the can side wall 16.
  • the insert 18 is retained in place in the can by a clip 20 (see Figures 1 and 2b) and by the domed bottom wall 14 of the can.
  • the clip 20 has a central generally annular ring portion 21 from which a number of arms 22 project outwardly and is conveniently injection-moulded from a suitable food- grade plastics material.

  • the clip 20 is generally frustoconical in appearance.
  • Outer end portions 26 of the arms are curved with a curvature similar to that of a portion of the internal surface of the can side wall 16 which the end portions are, in use, intended to engage.
  • the clip 20 is received in an upper end portion of the can 10, the arms 22 being slightly too long, so that they slightly press, resiliently, against the side wall 16.
  • the ring portion 21 is spaced by the arms 22 remotely from the upper end wall 12 of the can and the clip engages the insert 18 to retain it in place, between the clip and domed bottom wall 14, as shown in Figure 2b.
  • the can 10 is filled in the usual way, after the insert 19 and clip 20 have been put in place.
  • the flow of beverage from the container is barely affected by the clip 20 in view of the open nature of the ring portion 21 and the openings 24 in the arms.
  • an insert 18 of area 625 cm 2 of an appropriate grade of TYVEK is required (e.g. 12.5 x 50 cm) having a configuration generally as shown in Figures 2a-c of the drawings. Slightly lower surface areas
  • the pleated sheets of TYVEK may be treated during their manufacture so as to ensure that the entrapped gas is C0 2 .
  • the performance of foam generation upon dispense of the beverage is temperature-sensitive and, in addition to a suitable surface area of TYVEK of appropriate grade, requires certain conditions of dissolved gas content in the beverage and certain differential pressure between the headspace above the beverage in the can 10 and atmospheric pressure.
  • a suitable dissolved gas content for the beverage has been found to consist of 1.5 vol/vol C0 2 and 60 ppm N 2 , and a suitable headspace pressure has been found to be 1.2 bar absolute.
  • dissolved gas contents may be present in other beers and details may differ where other beers are to be dealt with, for example 2.8 vol/vol dissolved C0 2 but no dissolved N 2 .
  • the details in such systems may be adjusted to produce the desired result when opening a can.
