Definitions

  • This invention relates generally to carbonated beverages including alcoholic beverages such as stout and traditional ales which are sold in packaged form ie in sealed bottles and cans.
  • One proposal involved injecting gas under pressure into the secondary chamber from outside the can using a hypodermic needle type of device and then resealing the can after the supplementary chamber had been pressurised.
  • the pressure which currently exists in such cans after the can has been filled and sealed and which is generally created by nitrogen dosing using liquid nitrogen just before the top is fitted to the can.
  • the supplementary chamber is preferably located at the bottom of the can so that the bubbles which emanate from the chamber have maximum froth producing effect, the can has to be inverted so as to cause communication between the secondary chamber and the gas in the head space so that the latter can permeate into the secondary chamber through the tiny orifice through which the gas will bubble when the can is depressurised.
  • can inversion can Whilst it is commonplace to invert cans on canning lines prior to pasturisation, can inversion can .represent something of a problem since the cans are primarily designed to stand on their base and not on their top. Should a can become unstable as a result of passing through a can twist, and fall or jam, it represents a considerable hazard since a fallen can on such a line can result in damage and certainly a serious stoppage of the line.
  • a beverage package comprising a cannister which is pressurised after being partly filled with a beverage having gas dissolved therein, and a secondary chamber therein comprising a housing within which gas can be trapped, a restricted orifice in the wall thereof through which gas or other fluid trapped within the container can be forced under the influence of internal pressure within the housing when the cannister is depressurised when opened for dispensing, means for fixing the housing at a desired height within the cannister such that the housing is normally submerged below the surface of the beverage in the cannister and is separated from any gaseous head space at the top of the cannister above the beverage, passage means extending from the housing into the upper regions of the cannister so as to permanently communicate with the head space when the can is upright, and non-return valve means in the passage means or in the housing, or both, so that gas can only flow from the head space into the housing and not vice versa.
  • any beverage which enters the secondary chamber via the restricted orifice during the filling process will be expelled via the restricted orifice if the level of beverage therein rises above the orifice.
  • the orifice By positioning the orifice relatively low down in the housing so the volume thereof which can become filled with beverage can be reduced thereby optimising the volume of the housing available for gas to be stored therein under pressure and which when the can is broached is available for forming the head on the beverage.
  • the non-return valve and passage means has a lower resistance to fluid flow than does the restricted orifice so that the secondary chamber is preferentially charged with gas.
  • Selection of appropriate cross-section areas for the passage means and the restricted orifice will ensure that it is predominently gas from the headspace which enters the container and not beverage via the restricted orifice.
  • the housing container may be made relatively small in cross- section so as to pass straight through a narrow restricted end of a can or bottle and may be provided with resilient fingers to centre the device within the cannister and by making the passage means a relatively rigid structure which extends upwardly to engage the underside of the lid when the latter is fitted in place, the passage means for communicating between the head space and the secondary chamber housing can be used to maintain its position at the lower end of the cannister.
  • the container is preferably constructed so as to have a well within which any beverage or liquid which has somehow entered the container will be contained well clear of the exit orifice.
  • the secondary chamber housing preferably includes internal passage means communicating between the restricted orifice at one end and an upper region of the housing so that a considerable depth of liquid can exist within the container before there is any possibility of the beverage in the housing being able to leave through the orifice instead of gas.
  • Fig 1 is a diagrammatic cross-section elevation of a can having a capsule containing gas under pressure and a passage means associated therewith in accordance with the invention
  • Fig 2 is a bottom view of the capsule in the can
  • Fig 3 is a top view of the capsule in the can
  • Fig 4 is a diagrammatic cross-section elevation of another secondary chamber embodying the invention.
  • Fig 5 is a top plan view of the other embodiment.
  • Fig 6 is a perspective view of the secondary chamber shown in Figures 4 and 5.
  • the can is designated 10 and the beverage within the can is designated 12. Above the beverage is a headspace 11 of gas under pressure. A capsule containing some of this gas under pressure for head generation on dispensing is designated 14. A small orifice 16 in a lower frusto-conical wall of the capsule 14 allows gas to leave the capsule 14 when the can 10 is broached in a conventional manner to dispense the beverage.
  • a tube 18 extends almost to the lid 20 of the capsule 14 so as to render the capsule less sensitive to orientation of the can during dispensing and thereby prevent any beverage which has entered the capsule from closing off the orifice as it swills around within the capsule during dispensing.
  • a filler tube 22 extends through the lid 20 of the capsule 14 up to and into the head-space 21 above the beverage 12 and which contains gas under pressure typically in the range 2 to 4 bar.
  • the tube 12 extends into the headspace 11 when the can is in its normal upright position, clearly if the can is tilted or upended this will no longer be the case and to this end a non-return valve 24 is provided to prevent gas which has entered the capsule from leaving it.
  • the non-return valve 24 is closed with a small positive pressure as by a light spring so that in the event that the can is inverted, there is little tendency for liquid to penetrate past the non-return valve and enter the chamber 14.
  • the orifice 16 may be closed with a plug of soluble material such as gelatine or may be covered by a bursting disc designed to fracture only from internal overpressure caused by the eventual opening of the package for consumption.
  • the tube 20 is shown extending to engage the underside of the lid 26 and the upper end of the tube may be closed and one or more openings such as 28 are provided in the wall of the tube above the valve 24 so as to allow gas to enter the tube 22 from the head space 11.
  • Three equidistant flexible fingers 20, 32, 34 extend generally radially from around the capsule to engage the inside wall of the can 10. In this way the capsule will be held centrally within the can and will be held near the bottom of the can by virtue of the upstanding tube 22.
  • a non-return valve may be associated with the orifice 16 typically in the form of a small buoyancy member which lodges against the orifice to close it off when the capsule is submerged in a liquid.
  • an over-pressure such as will exist when the can is broached
  • the pressure of the gas within the capsule will displace the small buoyancy member away from the orifice to enable gas from within the capsule to be expelled and form the string of bubbles needed to produce the head formation.
  • the invention is of primary application to alcoholic beverages on which a head is desired when dispensed, it is equally applicable to non-alcoholic carbonated beverages and the like.
  • the tube 22 allows the capsule 14 to be filled with gas during the can filling process. To this end the capsule is inserted into the can immediately before filling with the beverage. The beverage is poured in until the headspace 11 exists. A source of liquid nitrogen under pressure is attached to the upper end of the protruding tube 22 and a small charge of liquid nitrogen is injected into the tube and thereby into, the capsule 14. Immediately thereafter the lid 26 is secured by seaming in known manner to the can.
  • the liquid nitrogen charge within the capsule will boil and evaporate to form gas which because of the non-return valve 24 will all bubble out through the orifice 16 until the headspace pressure and the pressure of the gas remaining within the capsule are equal.
  • the capsule will be charged wholly from within and if a gelatine or like seal or a bursting disc seal or a flotation member normally closing off the orifice 16 is provided, capsule interior will remain totally dry and contain only gas.
  • the presence of the non-return valve 24 will prevent the ingress of beverage to the capsule 14, and all of the volume of the capsule will therefore be available for storing gas under pressure until the can is broached when the gas will exit as a stream of bubbles through the orifice 16 to form the foaming head.
  • the tube 22 is off centre so that the device is assymetrical.
  • the capsule is 36 and the tube 38.
  • the upper end of 38 indicated as opening 39 and one way valve 41.
  • the internal tube 18 is also relocated so as to be coaxial with the tube 38 as shown at 40.
  • the orifice 16 is replaced by a small orifice 42 in an extension 44 of the tube 40 which protrudes centrally through the base of the capsule 36.
  • Radial wings 48, 49, 50 extend from the capsule 36 to engage the inside of the can 10.
  • Upwardly inclined radial fingers 52, 54, 56 extend from the upper end of the tube 38 to engage the can just below the lid 58.
  • the upper end of the tube 38 is located just below the lid 58 so that the capsule is held in position at the bottom of the can, even though its bouyancy tends to force it upwards.

Abstract

Un emballage pour boisson comprend une boîte (10) en deux pièces équipée d'une chambre secondaire (14) conçue pour contenir un volume de gaz sous pression. Lorsque la boîte est ouverte, juste avant de verser (ou de boire la boisson (12) directement depuis la boîte), ce volume de gaz est diffusé depuis la chambre, via un petit orifice (16) ménagé dans la paroi de la chambre. La chambre secondaire comprend un tube allongé (22) s'étendant depuis la capsule en direction du haut, et qui s'arrête juste sous le couvercle (26) de la boîte. Une ouverture (28) dans la paroi du tube communique avec l'espace libre au-dessus de la boisson dans la boîte. Un clapet à une voie (24) est positionné dans le tube et il est conçu pour éviter l'entrée de la boisson. Le petit orifice (16) dans la paroi de la chambre secondaire peut être obturé par un tampon de gélatine qui va se dissoudre à une certaine température. Dans une variante, l'invention décrit un disque de rupture incorporé qui nécessite seulement une chute de pression lors de l'ouverture de la boîte pour se rompre et permettre au contenu de la chambre de pénétrer dans la boîte et commencer le processus de formation des bulles.
