Abstract

A container for beer or other liquid having natural or enhanced carbon dioxide in the solution has a closeable inlet aperture 12, a closeable aperture 18 for dispensing the liquid and a third aperture 20, an open mouth of a bag 22 which is located inside the container being sealed around the third aperture 20, the bag being of a material having a low permeability to oxygen and carbon dioxide and being of a size and shape which is such as to allow it, when full, substantially to fill the inside of the container. As liquid such as beer is dispensed from the container air passes into the bag so causing the bag to expand within the container and prevent direct contact between the liquid and air. The three apertures may all be provided in the end surface of a removable screw cap 6. A pressurised air reservoir and a pressure regulator may be attached to a nipple 26 provided at aperture 20. Air from the reservoir may maintain a positive pressure on the beer so helping in the dispensing and also inhibiting the evolution of carbon dioxide from the beer. <IMAGE>

Description

SPECIFICATION Carbonated beverage container This invention relates to dispensing containers for beer or other liquid having natural or enhanced carbon dioxide in solution and which may deteriorate if allowed to remain in contact with air.
Such a container in accordance with this invention may be of barrel or cask shape, and has extending through one wall, and preferably only one wall, a closable inlet aperture for liquid means, such as a tap, for dispensing liquid contents of the container and an aperture passing through the wall around which an open mouth of a bag, which is located inside the container, is sealed, the bag being of a material having a low permeability to oxygen and carbon dioxide and being of a size and shape which is such as to allow it, when full, substantially to fill the inside of the container.
In use the container is first filled with beer or the like through the inlet, the bag being in a collapsed state, pressed against an interior wall of the container. As beer is dispensed through the tap, the bag which is opened to atmosphere or to a source of pressurised air or gas through its connection to an aperture through a wall of the container, expands so that the air or gas in the container above the level of liquid, is separated from the liquid by a wall of the bag. This means that the liquid is less readily oxidised by direct contact with the air and more readily retains its carbon dioxide content resulting in a longer storage and use life.
The container is preferably made of a material with good barrier characteristics such as for example as Polyethylene Terephthalate and may be made, for example, by an injection blow-moulding process and have an approximately cylindrical or spherical form to resist internal pressure An end cap may then be provided to allow the container to be stored in an upright position and used whilst being held for example on a cradle, with its main axis horizontal. The wall through which the inlet opening and tap pass, is in effect then an end wall and the top will be located near the bottom of that wall for convenient dispensing.
Alternatively the container may be made by an injection moulding process in two parts joined together by a screw thread, welding or adhesive joint.
If the bag within the container is attached to a compressed air reservoir which acts to inflat the bag as part of the contents are dispensed. A pressure regulator may be used between the reservoir and the air bag to limit the internal pressure in the container. This maintains the contents of the container under positive pressure without direct contact with air or the use of the carbon dioxide cylinders. This, in turn, inhibits the evolution of carbon dioxide from the contents and helps to maintain the beer or other beverage in good condition.
The invention will now be further described with reference to the accompanying drawing which is an elevation of a container in accordance with the invention with the end cap shown separated from the body.
Referring to the drawing the container has an approximate cylindrical or spherical body 2, the open end of which is formed with a screwed collar 4 to receive a similarly screwed end cap 6. The other end of the container is provided with a fixed end cap 8 to enable the container to be stored in an axially upright position resting on the end surface 10 of the fixed end cap.
The cap 6 has an inlet 12 through which the container may be filled and after filling, this inlet 12 is sealed by a cap 14. A tap 16 is mounted in an outlet passage 18 also passing through the end wall of the cap 6 to enable the contents of the container to be dispensed when the container is held in the horizontal position depicted in the drawing.
A further aperture 20 is formed through the same end surface of the removable cap 6 as the apertures 12 and 18 and a bag 22 shown in a collapsed position in the drawing has its open mouth sealed at 24 around the open end of the inlet passage 20.
In use and with the cap 6 tightly secured to the collar 4 of the container and after the container has been filled with beer through the filling hole 12 and sealed by the cap 14, beer may be dispensed using the tap 16. As the level of beer falls, air is sucked into the container through the inlet passage 20 into the interior of the bag 22 which expands to fill the space in the container above the level of the beer.
The bag is made of a material such as that known under the name "Saranex" (made by the Dow Chemical Co. Ltd., of Bath Road, Hounslow, Middlesex) which has a low permeability to oxygen and carbon dioxide so that the beer remaining in the container is not in contact with the air in the bag and there is virtually no other air within the container which would tend to cause the beer to deteriorate.
In a modification, a pressurised air reservoir may be attached to a nipple 26 extending out from the end cap 6 and communicating with the inlet 20.
Then as beer is dispensed, the air pump is operated to inflate the bag 22 with pressurised air. This maintains a positive pressure on the beer to help to dispense the beer and also inhibits the evolution of carbon dioxide from the beer which helps to maintain it in good condition.
