Definitions

• the present invention relates to containers (including flexible bags and liners) for mixing of various solids, liquids, and gases and combinations thereof, and systems and methods for sealing such containers.
• mixing devices for industrial use have utilized glass tanks for processing small volumes of components, and a stainless steel tanks for larger volumes. Screws or impellers may be used to agitate and maintain powders within suspension, and to homogenize multiphase solutions.
• traditional mixing tanks Prior to use, traditional mixing tanks must be washed and sterilized - such as employing an autoclave to wash and sterilize a small volume tank, or a water- and steam-based operation to wash and sterilize a larger volume tank.
• wash, sterilize, and process operations which are essential to the specified technologies, are typically time-consuming and expensive, and require highly qualified individuals for their performance.
• periodic maintenance of mixing devices associated with the various technologies must be performed to ensure proper operation. In certain cases, washing/sterilizing operations as well as the maintenance of these mixing devices may represent more than a third of the total cost of operating and maintaining such mixing devices, which may be prohibitively expensive for given applications.
• disposable containers such as processing bags
• processing bags have been developed to enable processing of substances without need for washing and sterilizing steps.
• disposable products such as storage bags
• storage bags which can range in size from ten to more than 3,000 liters.
• Current uses include storage of products or components awaiting further processing steps such as purification.
• stored products or components e.g., emulsions and suspensions
• a magnetic stir bar or magnetically actuated stirring element may be used.
• a mixing element may be operatively coupled with a mechanical driver and arranged to travel within an interior of the container.
• FIGS. 1 and 2A-2D Examples of disposable fluid processing containers and portions thereof are disclosed in U.S. Patent Application Publication No. 2009/0323466 entitled "SYSTEMS AND DEVICES FOR MIXING SUBSTANCES AND METHODS OF MAKING SAME" (and commonly assigned to the same assignee as the present application), and still further examples are shown in FIGS. 1 and 2A-2D.
• a fluid processing (e.g., mixing) container 10 that is cylindrical in shape may include a side wall 10, a bottom wall 12, and a top wall 14. Such walls may be formed of flexible polymeric film material.
• a sleeve 20 may be fabricated from two flexible sheets 16A, 16B of polymeric film materials, and sealed along edges thereof (e.g., by ultrasonic welding along edges including a bottom edge 17) around a mixing paddle 25 and associated shaft 24, with an interior 18 of the sleeve 20 being isolated from the interior volume of the container 10 by the sealed sheets 16A, 16B.
• the two sheets 16A, 16B are affixed to the top wall 14 of the mixing container 10 proximate to a coupling guide 15.
• the coupling guide 15, which is typically more rigid than the mixing container 10, enables coupling of the shaft 24 to a mechanism (not shown) external to the container 10 for causing the shaft 24 and paddle 25 to move within the interior volume of the container 10.
• the shaft 24 is moved within the container 10 in a closed path parallel to the bottom wall 12, but without continuous rotation of the shaft 24 about its own axis, in order to prevent twisting and potential failure of the sleeve 20.
• the fitment 30 is typically more rigid than the walls 10, 12, 14 of the disposable (e.g., flexible) container, to provide suitable sealing capability.
• FIG. 2A Another disposable processing container is shown in FIG. 2A.
• the rectangular shaped container 50 includes side walls 51, a bottom wall 52, and a top wall 54.
• a coupling guide 55 affixed to the top wall 54 provides an external interface for a mixing element within the container 10.
• Ports 48, 49 are disposed along the top wall 54 and a side wall 51, respectively.
• a fitment 80 is arranged along the top wall 54, with a gasket 90 disposed along a top surface of the fitment 80 to promote sealing with a removable cover (i.e., cover 95 as illustrated in FIG. 2C).

• a fitment is typically located at the top of a flexible container, and such container may be partially filled with material, thus leaving the fitment and mating parts unsupported and not horizontally level (since a partially filled non-rigid liner or bag will conform to an underlying surface).
• a conventional sealing apparatus a user may need to support a fitment with one hand while attempting to apply the sealing apparatus with one other hand.
• a user may need to align a gasket and cover while attaching and tightening a clamp.
• Another factor than can influence alignment of the parts and integrity of a resulting seal is differing dimensional tolerances of the part feature and related manufacturing variations.
• a flexible gasket will adopt subtle deformations, protrusions of the gasket may not always properly align to corresponding depressions or grooves in the fitment and cover, such that the gasket may be forced into an improper position whereby the desired seal is not created.
• misalignment between a gasket 90A and a fitment 80A can lead to formation of a gap G that inhibits establishment of a proper seal.
• alignment mismatch together with the inherent difficulty of supporting and manipulating multiple parts to accomplish the desired seal, can cause significant user frustration.
• the sealing process is even more burdensome in a cleanroom environment, since it is common practice for users in such environment to wear multiple layers of elastic gloves.
• the cap and/or the fitment may be formed of rigid polymers having a different rigidity than the soft (e.g., elastomeric) gasket, it may not always be apparent when the gasket is misaligned.
• liquid-based compositions and process liquids may be exceedingly expensive or difficult to produce, and loss or contamination of fluid may require shutdown of a manufacturing process or manufacturing delays.
