A bag-in-box container includes a box defining a cavity receiving a bag. The bag includes walls formed of plastic sheet material forming a variable-volume chamber, and a fitting carried on one of the walls provides a passage communicating with the variable-volume chamber. The fitting is formed of material which is essentially impermeable to oxygen. A method of sealingly attaching the fitting to a wall of the bag without the use of heat sealing or adhesives is disclosed.

A two-part connector structure (22, 32) includes a male connector part (32) and a female connector part (22) which are mutually engageable to open fluid communication between the connector parts (22, 32). For example, the connector parts (22, 32) may be used to establish fluid communication between a container (12) and a conduit (14). The connector parts (22, 32) are disengageable from one another to discontinue fluid communication between them, and also to close communication between ambient and each of the container and the conduit. The male connector part (32) includes a mounting structure (32a) for supporting on the female connector part (22), and also includes a guide structure (44) effective to guide a male portion (36) of the male connector part (32) into engagement with the female connector part (22). A handnut (34) of the male connector part (32), and is effective upon manual rotation to cause axial relative movement of the male probe portion (36) into or out of engagement with the female connector part (32). This invention provides a connector structure (22, 32) with considerably lowered manual engagement and disengagement forces, along with increased convenience and ease of use.

A liquid-dispensing tap includes a tap body which is mountable to a container holding liquid, a seal member disposed within the tap body, and an actuator connected to the seal member. The actuator is pivotally disposed on the tap body so that when pivoted by a user, a seal formed between the seal member and the tap body is disengaged, allowing liquid within the container to dispense. The actuator may be pivoted in any number of predetermined directions. The tap may be manufactured and assembled to consist essentially of only the tap body, the seal member, and the actuator, thereby eliminating many other elements commonly found in conventional taps.

A two-part coupling structure includes a male coupling part and a female coupling part which are mutually engageable to open fluid communication between a fluid-storage vessel and a conduit, for example. The coupling parts are disengageable from one another to discontinue fluid communication between the vessel and the conduit, and also to close communication between ambient and each of the vessel and conduit. The retention volume of fluid which is trapped between the connected male and female coupling parts and which is exposed to or lost to ambient when the coupling parts are disconnected is very small. The male coupling part is carried in a guide structure which is removably engageable with the female coupling part to guide the male coupling part into engagement. Also, the male coupling part and its guide structure define cooperating structural features which effect opening of the male coupling part in response to advancement relative to the guide structure. Consequently, the male coupling part can be opened without being connected to a female coupling part, for example, for cleaning and inspection, as well as for replacement of a sealing member.

The retention volume of fluid which is trapped between the connected male and female coupling parts and which is exposed to or lost to ambient when the coupling parts are disconnected is very small. Because of particular structural features, the coupling parts will function reliably even with fluid having chunks or particulates of non-fluid material therein.

A container of draft beer is substantially filled with beer having a volume of dissolved carbon dioxide greater than 2.6 and not more than 3.1 times the volume of beer. The beer is packaged in a plastic container that is slightly permeable to carbon dioxide, but retains a satisfactory dissolved carbon dioxide content even after a normal shelf life. Beer is dispensed by gravity, without use of external pressure source, after release of head space pressure. Moreover, when the container contents are partially dispensed by the consumer and then maintained at appropriate low temperature for several days, the remaining beer still retains a satisfactory volume of dissolved carbon dioxide. A spigot on the container employs a barrel valve closure member that seals the pressurized container and is movable to a pressure release position in which pressurized gas within the container is slowly released without forcibly projecting container contents. The barrel valve closure is movable to a dispensing position in which the contents of the container are smoothly dispensed while air is admitted to avoid a blocking vacuum.

This invention provides a dispenser for a beverage, such as beer, in which the contents of the container are pressurized by gas from a cartridge in the container. A pressure responsive member in the container is movable in response to differences in pressure between that of the atmosphere and of the inside of the container. A valve member is carried by the pressure responsive member and includes a tapered pin for forming an opening through a diaphragm over the cartridge outlet and metering the discharge of gas from the cartridge in response to movements of the pressure responsive member.

A container for holding and dispensing fluid has a flexible bag to which a spout is connected. A specially designed adapter within the spout has an opening sealed by a plug. A tubular probe is inserted into the adapter opening and snapped onto the plug. The connected probe and plug are pushed into the bag to permit fluid to flow through apertures in the probe. The probe channel is filled with fluid before insertion into the bag, thus introducing substantially no air into the system. Withdrawing the probe snaps the plug back into the adapter to re-seal the bag without substantial introduction of air, and without any leakage.
