摘要:
A sterilization system for use in association with a filler device configured for filling at least one of rigid and flexible containers comprising a sterilization chamber and a sterilant supply assembly. The sterilization chamber includes a housing, an inlet into the housing, an outlet from the housing and a product retainer assembly. These components define a cavity within which to position a portion of a fitment. The sterilant supply assembly comprises a steam generating system having a steam supply conduit extending therefrom and a joint mixing conduit coupled with the inlet into the housing of the sterilization chamber, a hydrogen peroxide storing system and a member for metering liquid phase hydrogen peroxide from the hydrogen peroxide storing system into the steam supply conduit for mixing therewith, and, in turn, introduction thereof into the cavity of the sterilization chamber.

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 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.
