A two-part coupling structure (22, 32) includes a male coupling part (32) and a female coupling part (22) which are mutually engageable to open fluid communication between the coupling parts (22, 32). For example, the coupling parts (22, 32) may be used to establish fluid communication between a container (12) and a conduit (14). The coupling 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 (12) and the conduit (14). The male coupling part (32) includes a mounting structure (44a-44e) for supporting on the female coupling part (32), and also includes a guide structure (44) effective to guide a male probe portion (36) of the male coupling part (32) into engagement with the female coupling part (22). A rotary actuator member (34), preferably in the form of a handnut is included in the male coupling part (32), and is effective upon rotation of cause axial relative movement of the male probe portion (36) into or out of engagement with the female coupling part (22). A considerably lowered manual engagement and disengagement force is provided, along with increased convenience and ease of use for the coupling structure.

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 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.

A flexible drum liner assembly having a fitting which mates with a specially cut hole in the lid of the drum. The fitting of a preferred embodiment of the present invention has a mouth with internal and external threads. A standard externally threaded bung hole cover fits in the mouth and mates with its external threads. A vertical slot is cut on either side of the mouth of the fitting interrupting the external threads. A circular bung hole with two opposed inwardly directed tabs is cut into the lid of the drum. The two tabs act as keys and fit into the keyways defined by the vertical slots on either side of the mouth of the fitting.

Filling and sealing devices and methods of aseptically filling containers are disclosed herein. More specifically, the filling and sealing devices include a sterile filling chamber and an induction sealing device provided within the filling chamber. The induction sealing device is capable of withstanding and operating in the adverse conditions required to maintain the sterile environment within the filling chamber. Within the filling chamber, the container may be uncapped, filled, recapped, and foil sealed by an induction sealing process.

The fluid dispensing device includes a tubular spout attachable to a fluid-containing vessel, such as a bag, the spout including an outer end portion of a first lateral dimension and an inner portion of a smaller lateral dimension. A valve member is slidable in the spout, the valve member being tubular and having an open outer end adapted to receive a fluid-transmitting probe and a closed inner end. The valve member has openings through its sidewall. The outer end portion of the valve member is laterally outwardly deflectable and includes localized protrusions adapted to enter the recess of a probe. In the closed position of the valve member, opposed shoulders of the valve member and of the spout resist axial movement of the valve member in either direction, and interengaged sealing surfaces block fluid flow to the openings. The outwardly deflectable portion of the valve member can be deflected as the probe enters, and the protrusions thereafter spring inwardly into the recess of the probe. The valve member then is movable by the probe to an inner open position in which the openings are uncovered, and the protrusions in the probe recess allow the valve member to be moved back to the closed position.

A spigot for association with a spout connected to a container, the spigot including a cylindrical portion to fit over the end of the spout, a diaphragm for engaging the end of the spout to prevent flow of liquid, a toggle member for deflecting the diaphragm and an opening through the cylindrical portion for dispensing liquid upon the deflection of the diaphragm. The spigot includes a downspout extending from the opening and having a sealed outer end which is of a relatively thin-walled construction, the downspout having a thicker wall inwardly of the outer end to prevent collapse of the downspout during deflection of the diaphragm. The spigot member includes a relatively thin-walled portion inwardly of the thickened part of the downspout for facilitating deflection of the diaphragm. The spigot may be sealed by heat sealing together opposed wall portions of the downspout or by a tab heat sealed over the end of the downspout. The tab is a lamination of heat sealable and non stretchable materials, and may be integral with a cover which extends over and is heat sealed to the end of the spigot.

A flexible bag container (10) is filled by a system (500) and method for filling the bag container (10). The flexible bag container (10) has a pair of walls (12, 14) and a spout member (18) attached to one side wall of the container. This spout member is opened and closed in the filling system. A plug member (22) is inserted into the spout member (18) from outside of the bag container (10) and is withdrawable in the opposite direction in order to open the bag container. The bag container is filled via the spout member after removal of the plug member outwardly of the bag container and into a filling head, and then the plug member is replaced from within the filling head into the spout member to close the bag container.

A tap for dispensing fluid from a vessel includes a main tap body, an actuator, and a seal member. The main tap body includes a passage with an inlet and an outlet and a seat with a shoulder formed around the outlet. The actuator has a handled and is pivotally attached to the main tap body and dispenses fluid from the vessel upon activation of the handle by a user. The seal member is received within the seat and attached to the actuator. The seal member includes a retaining portion received against the shoulder of the seat and a sealing portion which is releasably engageable with the seat. The seal member is resilient to provide a bias force to urge the sealing portion against the seat. The actuator is pivotal between a closed position in which the sealing portion is biased against the seat, thereby preventing fluid from passing through the outlet, and an opened position in which at least a portion of the sealing portion is pulled away from the seat against the bias force, thereby allowing fluid to flow through the outlet.
