摘要:
There is provided a bottle beverage packaging apparatus and method in which an open topped bottle 20 having a primary chamber charged with beverage 21 containing gas in solution is enclosed together with a closure 8 in a pressure chamber 25 which may be formed against a shoulder of the bottle. The chamber 25 is pressurised with nitrogen gas to pressurise the primary chamber and a secondary chamber 14 in the closure 8 through an aperture 15 of the chamber 14 prior to the closure 8 being displaced by a closure locator 5 to seal the open top of the bottle in the pressurised chamber 25. A projection 11A from the secondary chamber 14 extends into the beverage 20 to locate the aperture 15 beneath the surface thereof. Following sealing of the bottle the chamber 25 is de-pressurised and opened for removal of the sealed package. The chamber 25 may be formed by a tubular shroud 2 carried by a rotating carousel. The secondary chamber 14 may be formed in a hollow insert separate from the closure 8. There is also provided a beverage package in which the closure which may be fitted by the apparatus and system includes a manually openable vent that reduces a headspace pressure in the sealed package to atmospheric pressure for gas to be injected into the beverage through the aperture 15 for froth development prior to removal of the closure from the bottle.

A beverage package and a method of packaging a beverage such as beer containing gas in solution has a container can 1 having a primary chamber 1A charged with beer 14 to form a small headspace 15. The can 1 is sealed and includes a submerged insert 8 forming a relief chamber 6 which is sealed by a closure 11. The insert 8 is responsive to heat applied during pasteurisation which causes the closure 11 to open the relief chamber so that the latter can accommodate beer derived from the primary chamber 1A to provide an enlarged headspace 15A. The small headspace 15 initially provided facilitates removal of air therefrom prior to sealing of the container while the enlarged headspace 15A is adequate to accommodate froth or foam developed by the intentional liberation of gas from solution in the beer. An insert part 7 forming a secondary chamber 5 may be provided for injecting gas or liquid into the beer to liberate gas therefrom for froth or foam development in the enlarged headspace. The relief chamber 6 may contain gas under pressure so that when opened to the primary chamber the release of such gas pressurises the enlarged headspace 15A. The insert part 7 may be located within the relief chamber 6.

A method and apparatus for providing pieces of flexible material from a length thereof (such as tubes 30 from plastics tubing 4) has a rotor 6 with a port 9 through which the tubing 4 is fed. Rotation of the rotor about its axis 7 displaces an end 4' of the tubing over a cutter 15 to cut the tube piece. The tube piece 30 may be gripped by jaws 23 on a turret 20 and carried to a transfer station 31 at which the tube piece 30 may be picked up by jaws 71 on a vertically displaceable head 60 of a locating unit 3. The head 60 rotates with a turret 56 and is displaced vertically under cam control 62, 63 for fitting an end 30A of the tube piece into a component, such as an open topped container 40, in a seat 52 beneath the head 60. the container 40 may be conveyed to the seat 52 in a filling and sealing line for forming a beverage package.
摘要:
A liquid dispensing system, primarily for beverage, has an array of containers 1 from which liquid is to be dispensed simultaneously by gas under pressure in the headspace of those containers. Liquid is dispensed from each container through an isolating valve 5 and a common delivery tube 8 to a dispensing tap 9. Each valve 5 includes a float which responds to density of fluid therein and when sensing liquid provides communication between its container 1 and the tap 9 and when sensing gas or foam therein from its container closes communication between its container and the tap 9. Alternative forms of isolating valves 5 may be used that are responsive to variations in electrical conductivity of fluid flow or variations in light absorption or refraction of fluid flow.

摘要:
A beverage package and a method of packaging a beverage having gas in solution has a sealed bottle 1 with a primary chamber 9 containing the beverage and forming a primary headspace 20 comprising gas at a pressure greater than atmospheric. A hollow plastics moulded pod 10 forms a secondary chamber 17 which communicates with the beverage 19 by way of a restricted orifice 18. Beverage from the chamber 9 enters the chamber 17 by way of the orifice 18 and when the beverage is in equilibrium a secondary headspace 21 is formed in the insert. Upon opening the bottle 1, the pressure differential between the headspaces 20 and 21 ejects beverage from the insert 10 through orifice 18 to develop froth on the beverage. The insert 10 carries a permanent magnet 15 which is encapsulated within the plastics. The magnet 15 is attracted to a metallic strip 8 on the bottle base to retain the insert at its desired location in the bottle. The insert 10 is dimensioned to be dropped into position on the bottle base through the bottle mouth and in an alternative arrangement the permanent magnet is carried on the bottle base to attract a metallic strip carried by the insert 10.
摘要:
A fluid pressure control valve and a fluid control system (such as for beverage dispensing) with such a valve has a beverage passage (3), pressure fluctuations in which are detected by a diaphragm (17) to displace a sensing member (15) axially against spring loading (23). Spring (23) reacts on thrust member (22) which is adjustable axially through a cam mechanism (25/26) to vary the biasing force of spring (23). A valve member (20) spring loaded at (21) relative to thrust member (15) normally closes an exhaust port (19) to an air or other gas passage (5) through which gas passes under pressure to be injected into the beverage from passage (3). An increase in beverage pressure in passage (3) displaces sensing member (15) to increase the spring biasing (21) on the closure member (20) and reduce the proportion of air which can escape to atmosphere from passage (5) through exhaust port (19) to provide an increase in air flow into the beverage. A reduction of pressure in passage (3) reduces the spring biasing (21) to permit a greater proportion of air to escape from passage (5) through exhaust port (9) and thereby reduce the proportion of air which is introduced into the beverage. The control valve can include a temperature sensitive unit responsive to temperature of beverage in passage (3) and which reacts to adjust the force of biasing spring (21) independently of pressure in the passage (3). Plunger (51) can be depressed manually to close the exhaust port (19) temporarily and thereby maintain maximum air pressure in the passage (5).
