摘要:
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.
摘要:
A collapsible bag for dispensing liquids which includes at least one sheet sealed to define an enclosure and a fitment (spout) attached to the enclosure and out through which liquid in the enclosure is dispensed. An interior surface of the one or more sheets has an integral texture to assist with withdrawal of the liquid from the enclosure when collapsed. The texture can be provided by sheet surfaces that are mechanically or ultrasonically embossed or are bubble-cushioned or which have sealed pleats or accordion folds. The bottom surface of a lower flange of the fitment may have concentric ridges (or spirals) and/or radial grooves. Also disclosed are methods of making the bag from one, two, three or four sheets.
摘要:
A method of aseptically and adiabatically processing liquid or semi-liquid food product at ambient temperatures so that the food product is transported from one sterile environment (such as a food processing machine), and into another sterile environment (such as a food package) via a food package filling machine head. During operation of the filling machine head, plural surface portions alternate between exposure to ambient and exposure to the food product. The method includes steps such that microbes from the ambient are not allowed to migrate along these alternatingly exposed surfaces. The method includes steps of initially heat sterilizing the alternatingly exposed surfaces at elevated temperature and pressure using culinary steam. Subsequently, an ambient temperature sterilizing barrier is maintained at a selected location along each of the alternatingly exposed surfaces so that migration of microbes along these surfaces and to the food product is prevented. After the initial heat sterilization using culinary steam, substantially adiabatic conditions are achieved for filling packages with the food product. Apparatus for carrying out the method is also disclosed.

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.
摘要:
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.
