Abstract: The present invention relates to an integrally blow-moulded bag-in-container (2) having an integrally blow-moulded bag-in-container wherein the same polymer is in contact on either side of the interface between the inner (11) and outer layers (12). It also concerns a preform(1, 1?) for blow-moulding a bag-in-container, having an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. The inner and outer layers are of the same material.

Abstract: The invention relates to a method of preparing a liquid, which contains proteins (esp. haze sensitive proteins), for subsequent separation of at least haze-forming material, when predetermined filter aids are used. The method comprises the addition of protein-complexing agent to the liquid, which agent is capable of forming a complex with at least some sensitive proteins of the liquid, to result in a limitation of the residual haze of the liquid, obtained after the separation (e.g. filtration), step.

Abstract: The invention is an integral two-layer preform for the production of integrally blow-moulded bag-in-containers. The preform has an inner layer and an outer layer, wherein the preform forms a two layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface of the two layers. The melting temperature of the inner layer is greater than or equal to the melting temperature of the outer layer.

Abstract: The invention is an integrally blow-moulded bag-in-container (2) obtainable by blow-moulding an injection moulded multi-layer preform (1). The bag-in-container (2) includes an inner layer (21) forming the bag and an outer layer (22) forming the container, and a single opening (5), the mouth, fluidly connecting the volume defined by the bag (21) to the atmosphere. The container further includes at least one interface vent (3) fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the bag (21) is anchored to the outer layer (22) at least one point (7) remote from the single opening (5) and interface vent (3).

Abstract: The invention is an integrally blow-moulded bag-in-container (2) and preform (1) for making it The bag-in-container (2) has an inner layer (21) forming the bag and an outer layer (22) forming the container, and a mouth (5) fluidly connecting the volume defined by the bag to the atmosphere. The container further has at least one interface vent (3) fluidly connecting the interface (14) between inner and outer layers to the atmosphere, wherein the at least one vent (3) runs parallel to the interface between inner and outer layers (21) (22) and opens to the atmosphere at a location (4) adjacent to, and oriented coaxially with the bag-in-container's mouth (5). Processes for manufacturing a preform and a bag-in-container as defined above are defined too.

Abstract: The present invention relates to an integrally blow-moulded bag-in-container and preform for blow-moulding the bag-in-container. An inner layer and an outer layer are used, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of said container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.

Abstract: There is disclosed a cask and chime assembly wherein the cask has end surface side wall portions of reduced diameter relative to the central wall surface portion of the cask. The reduced diameter portions of the cask are separated from the central wall surface portion of the cask by an annular groove whereby a protruding shoulder is provided in the groove adjacent the central portion of the cask. Chimes the cask and have a flange adapted to be snapped fitted into the groove. The shoulders provide for support against vertical of forces that might otherwise displace the chimes from the grooves.

Abstract: A tap adapter (38) for use in dispensing an alcohol beverage from a container (22) has a shoulder (152), a support arm (150), a dispensing tube, a flow restricting actuator (200), and a switch (300). The dispensing tube is supported by the support arm and provides a beverage flow passageway for dispensing beverage from the container. The dispensing tube has at least a flexible wall portion (86). The flow restricting actuator is pivotally attached to the shoulder and moves between a first position remote of the dispensing tube and a second locked position to partially collapse the flexible wall portion and restrict flow of beverage through the passageway. The switch, when actuated by a user, releases the flow restricting actuator from the second locked position. The switch of the tap adapter facilitates disconnection of the dispensing tube from a spent container and the changing of the dispensing tube.

Abstract: A beer keg for storing a beer under pressure has an outer wall and a pressure relief passageway extending through an outer wall of the beer keg. The beer keg has a bursting disk seated in the passageway normally closing the passageway. The disk is adapted to rupture permitting fluid to escape from the beer keg through the passageway when the pressure in the beer keg exceeds a predetermined pressure value. The keg has a releasable cap mounted thereto that covers the passageway. The releasable cap has vent openings that permit the escape of fluid from the passageway. The cap is releasable to permit access to the passageway for changing the bursting disk. Preferably, a pressure build up in the keg in excess of about 7 bar results in the bursting disk rupturing.
