This disclosure relates generally to a system for aseptically transferring a fluid from a fluid container. More specifically, the disclosure relates to an aseptic closure assembly including a cap and fluid dispensing assembly, method, and components for aseptically transferring the fluid from the fluid container.
Chemical and/or biological processes can utilize or produce process materials that are stored within storage containers, such as, bioprocess bags, bottles, and the like having rigid connection systems, containing pharmaceutical or biological fluids, acids, solvents, bases, photoresists, dopants, inorganic solutions, organic solutions, or the like. The process materials may need to be frozen or otherwise kept at low temperatures within the storage container. In using such fluids, the storage container needs to properly contain the chemicals during storage, transport, and ultimately during the manufacturing process itself. Currently, the methods and fluid transfer assemblies for transferring fluids to or from the storage container having rigid connection systems, however, cannot guarantee the sterility of the system.
This disclosure relates generally to a system for aseptically transferring a fluid from a fluid container. More specifically, the disclosure relates to an aseptic closure assembly including a cap and fluid dispensing assembly, method, and components for aseptically transferring the fluid from the fluid container.
In an embodiment, an aseptic closure assembly for a fluid container is provided. The aseptic closure assembly includes a cap connectable to an opening of the fluid container, the cap having a housing, a cavity within the housing having a support, and a first set of seals; and a fluid dispenser connectable to an outer surface of the housing of the cap. The fluid dispenser includes a main body having a first end and a second end and fluid lines provided within the main body between the first end and the second end, a shell housing provided around the main body, a second set of seals, and an insert connectable to the second end of the main body. The main body includes apertures nearer the second end that are connected to the fluid lines and configured to be in fluid communication with the fluid container when the fluid dispenser is connected to the cap. Additionally, the fluid dispenser is configured such that a downward directed force towards the fluid container fits the insert into the support of the cavity and disconnects the insert from the main body of the fluid dispenser to seal the fluid container.
In another embodiment of the invention, an aseptic closure assembly is provided that includes a cap connectable to an opening of the fluid container, the cap including a housing, a cavity within the housing, a port connected to the cavity, and a first set of seals. The port includes a port shell and an insert connected to one end of the port shell, in which the insert is configured to open and close a fluid communication channel between the fluid container and the port; and a fluid dispenser connectable to an outer surface of the port shell. The fluid dispenser includes a main body having a first end and a second end and a fluid line provided within the main body between the first end and the second end, a shell housing provided around the main body, a second set of seals, and an engagement piece that is engageable with the insert. The engagement piece of the fluid dispenser is engageable with the insert of the port by a rotational engagement such that the fluid line is able to be directed downwardly with the insert towards the fluid container to open the fluid communication channel with the fluid container.
In an embodiment, a method for aseptically transferring a fluid into and from a fluid container is provided. The method includes the steps of connecting a cap to an opening of the fluid container, the cap including a housing, a cavity within the housing, a port connected to the cavity, and a first set of seals. The port includes a port shell and an insert connected to one end of the port shell, in which the insert is configured to open and close a fluid communication channel between the fluid container and the port. The method further includes transferring fluid into the fluid container by aseptically connecting and disconnecting a fluid dispenser to an outer surface of the port shell, in which the fluid dispenser includes a main body having a first end and a second end and a fluid line provided within the main body between the first end and the second end, a shell housing provided around the main body, a second set of seals, and an engagement piece that is engageable with the insert. When the engagement piece of the fluid dispenser is engaged with the insert of the port by a rotational engagement, the fluid line is able to be directed downwardly with the insert towards the fluid container to open the fluid communication channel with the fluid container.
In yet another embodiment, a fluid dispenser connectable to an outer surface of a cap of a fluid container is provided. The fluid dispenser includes a main body having a first end and a second end, in which the main body includes a fluid line provided between the first end and the second end; and a shell housing provided around the main body. The fluid line at the second end of the main body is configured to be connectable with an insert provided in the cap by a rotation of the main body, in which the shell housing includes bellows that are compressible to allow the fluid line to be aseptically inserted into the fluid container.

This disclosure relates generally to an aseptic closure assembly for aseptically transferring a fluid from a fluid container. More specifically, the disclosure relates to an aseptic closure assembly that includes a cap and fluid dispensing assembly used to aseptically couple and transfer, e.g., filling and removing, of fluids from storage containers to avoid contamination. The term aseptic as used herein is at least related to creating a barrier or fluid path that remains unbroken between the fluid dispensing assembly and the fluid container to keep the fluid substantially free of contaminants from an external environment to maintain the sterility of the internal content and/or components. While the fluids related to chemical and/or biological processes are discussed below, it is appreciated that such discussion is not intended to limit the scope of the invention, but provided as embodiments thereof. A fluid includes, but is not limited to, a substance that flows or deforms when a shear stress is applied. A fluid can include, for example, a liquid.
For example, in the bioprocess market, customers perform freezing, shipping, and thawing of their drug products in a variety of fluid storage containers, such as, bottles, bags, pails, drums, or the like. While customers are able to transfer fluids to bag assemblies aseptically using a variety of aseptic connectors, the use of bottles, pails, drums, or larger bag assemblies is not as widely utilized since the transfer of fluids to or from the bottles, pails, drums, or larger bag assemblies cannot be made using a simple aseptic connection assembly, e.g., the transfer of fluid is not in a closed system and requires additional equipment or features for maintaining the sterility of the fluid, since a fluid transfer assembly is connected to the top of the bottle, pail, drum, or larger bag assembly. For example, customers may use bottles with caps on a top opening thereon that have tubing connection ports or have a polymer stopper covering the bottle top opening. While the caps can be used for aseptically filling the bottle and the polymer stopper can be used to close the bottle, in both instances, the customers are required to either remove the cap and replace it with a solid cap for the freezing, shipping, and thawing process steps or remove the polymer stopper to fill and/or remove the fluid, e.g., a drug product. The replacing of the bottle cap and/or the polymer stopper, however, opens the system and exposes the fluids in the bottle to the outside environment which can lead to possible contamination of the fluid. To limit and/or reduce the amount of contaminants that can enter the bottle during the replacing of the bottle cap and/or the polymer stopper, a hood can be used to attempt to maintain the sterility of the system. In order to simplify the filling and removing of the fluid from the bottle, e.g., not requiring the use of the hood or additional equipment to maintain sterility of the system, and to reduce the chances of contaminating the fluid in the bottle, a system is needed for aseptically transferring a fluid from the fluid storage container, such as a bottle, pail, drum, or the like.
Embodiments of the disclosure are directed to an aseptic closure assembly that includes a cap and fluid dispenser that allows the aseptic transfer of fluids from a fluid container, for example, a bottle or other fluid container having a rigid opening, e.g., a pail, bucket, or larger bag assembly having a rigid opening that is able to be fitted with the cap. It is appreciated that a rigid opening as used herein is at least directed to an opening that is formed on a fluid container made of a relatively rigid material, for example, from one or more polymers. For example, the fluid container can be made of polyethylene (PE), poly(ethylene terephthalate) (PET), poly(ethylene terepthate) glycol (PETG), polycyclohexylenedimethylene terephthalic acid (PCTA), polycyclohexylenedimethylene terephthalate glycol (PCTG), polycarbonate (PC), polypropylene (PP), poltamide (PA), polyethersulfone (PES), polyphenylsulfone (PPSU), poly(methyl methacrylate (PMMA), high impact polystyrene (HIPS), poly(ethylene napthalate) (PEN), poly(ether ether ketone) (PEEK), cyclic olefin polymers, cyclic olefin copolymers, fluorpolymer, or the like, and copolymers including those material.
The aseptic cap and fluid dispenser can include a multi-use aseptic cap that allows a user to aseptically connect and disconnect to a fluid storage container having a rigid opening, for example, a bottle or a rigid opening on a bag assembly, before and after freeze/thaw process steps. The aseptic closure assembly can allow users to fill the bottle before freezing and drain the bottle after thawing, without the need for replacing the caps and/or polymer stoppers during the filling and draining process, and avoids breaking of the sterile barrier and/or fluid path between the fluid dispenser and the fluid storage container. The aseptic cap and fluid dispenser allows the use of bottles as a closed system, e.g., prevents contamination of the fluid by being open to outside environments, to maintain the sterility of the fluid in the fluid handling system, and especially, for bioprocess fluid handling. It is appreciated that at least due to the design and structure of the aseptic closure assembly, the fluid storage container and aseptic closure assembly can be used in freeze/thaw process steps for down to −85° C. applications, in which there is currently no existing aseptic cap design that is rated for use in such conditions and especially for such top feed and removal devices. It is appreciated that while the description of the fluid storage container and aseptic closure assembly is discussed with respect to temperatures as low as −85° C., the fluid storage container and aseptic closure assembly can also be used at cryogenic temperatures, e.g., lower than −190° C. and even more preferably lower than −196° C.
Thus, the aseptic closure assembly 10 is configured to aseptically connect and disconnect from a fluid container for the aseptic transferring of fluids to or from a fluid container that can be used in temperatures as low as −85° C. It is appreciated that the aseptic closure assembly 10 can also be used at other temperatures, such as 0° C., room temperature, or the like, while maintaining the benefits of the present disclosure. Accordingly, the fluid container 1 having the aseptic closure assembly 10, as discussed above, is configured to be stored at frozen temperatures (e.g., temperatures of less than 0° C. and lower). In an embodiment, the fluid container 1 having the aseptic closure assembly 10 can also be heated back to ambient temperature without having any substantial deformation. Substantial deformation includes, for example, visible cracking in the material, a shrinkage or expansion relative to its original shape at ambient temperature that can interfere with the connection(s) or adversely affect sealing of said connection(s). Temperature retraction testing can be performed according to ASTM D1329, ISO 2921, or any other suitable testing methodology for determining suitable retraction properties of the material at temperatures that may be used. Brittleness testing can be performed according to ASTM D2137, ISO 28702, or any other suitable testing methodology for determining resistance to cracking at temperatures that may be used.
The fluid container 1 can generally be used for containing a fluid such as a liquid suitable for use in, for example, manufacturing and/or biological processes, such as, but not limited to, semiconductor manufacturing, pharmaceutical manufacturing, or biological processing, or the like. As such, it is appreciated that the fluid container 1 can store liquids including liquid chemicals such as, but not limited to, photoresists, acids, solvents, bases, dopants, inorganic solutions, organic solutions, pharmaceuticals, biological fluids, or the like.
In an embodiment, the fluid container 1 can be a plastic bottle and/or include a bag-in-bottle or can be a bag-in-can style container. In other embodiments, the fluid container 1 can be a bag assembly having a rigid connection structure, for example, boat fitments, fitments, plastic ports, or the like, or a combination of the above. It is appreciated that the container can be any type of container having a rigid opening 2 for attaching of the aseptic closure assembly 10, as discussed below. Such a fluid container 1 (or rigid connection structure) can be made of a relatively rigid material, for example, from one or more polymers. For example, the fluid container 1 can be made of polyethylene (PE), poly(ethylene terephthalate) (PET), poly(ethylene terepthate) glycol (PETG), polycyclohexylenedimethylene terephthalic acid (PCTA), polycyclohexylenedimethylene terephthalate glycol (PCTG), polycarbonate (PC), polypropylene (PP), poltamide (PA), polyethersulfone (PES), polyphenylsulfone (PPSU), poly(methyl methacrylate (PMMA), high impact polystyrene (HIPS), poly(ethylene napthalate) (PEN), poly(ether ether ketone) (PEEK), cyclic olefin polymers, cyclic olefin copolymers, or the like, and copolymers including those materials.
The cap 12 is connectable to the rigid opening 2 of the fluid container 1 to secure the cap 12 to the fluid container 1. The cap 12 can be connected to the fluid container 1 by press fitting the cap 12 to the rigid opening or the cap 12 and the rigid opening 2 can include mutually engaging threading. It is appreciated that the cap 12 can also be connected to the fluid container 1 in other manners, for example, using mechanical fasteners, such as, clamps, respective engagement features, or the like, or welding or bonding techniques, such as, heat bonding, impulse welding, laser welding, ultrasonic welding, or similar fusion bonding/melt welding techniques. In an embodiment, the cap 12 can be connected to the fluid container using a tamper evident connecting system. For example, the cap 12 having the tamper evident connection system can include inwardly biasing retaining arms that engage corresponding protrusions around the rigid opening 2 of the fluid container 1 once pressed to a predetermined position on the rigid opening 2 such that the cap 12 is not able to be easily removed from the fluid container 1 without leaving visible indications of damage to the cap 12 and/or the fluid container 1. In another embodiment, the cap 12 having the tamper evident connection system can include a protrusion at a lower portion of the threading, so that once the cap 12 is threaded to a predetermined position, the cap 12 is not able to be removed from the fluid container 12, e.g., by reversing the rotation of the cap 12 on the rigid opening 2. In yet another embodiment, the tamper evident connection system can include a ring on the cap 512, which separates from the cap 512, if the cap 512 is removed from the fluid container. Thus, the tamper evident connection system is able to alert a customer or user of the fluid container 1 having the cap 12 if the fluid container 1 has been opened, or attempted to be opened, and possibly contaminated and/or compromised.
The fluid lines 210 nearer the first end of the main body 205 can include a tube connector for connecting to a fluid transfer system for the transfer, e.g., filling or removing, of the fluid with respect to the fluid container 1. The tube connector can be selected from the group consisting of a hose barb, an overmolded connection, a screw connection, a press-fit connection, a snap-fit connection, or a combination thereof. It is also appreciated that the tube connector can be continuously formed with the fluid transfer system, for example, by molding or overmolding the fluid dispenser 14 with the fluid transfer system.
The main body 205 can also include apertures 206 provided nearer the second end that are fluidly connected with the fluid lines 210 and is configured to be in fluid communication with the fluid container 1 when the fluid dispenser 14 is connected to the cap 12. The fluid dispenser 14 can also include an expanded portion 230 that can be in fluid communication with the apertures 206 provided through the main body 205 so that when a fluid is supplied or removed through the fluid lines 210 of the fluid dispenser 14, the fluid flows from the apertures 206 through the expanded portion 230 and around the insert 225 into the fluid container 1 or from the fluid container 1 around the insert 225 through the expanded portion 230 and then through the apertures 206. In an embodiment, the fluid dispenser 14 includes first retaining features 235 for engaging the outer surface of the housing 240 of the cap 12, as discussed below.
As seen in
The cavity 245 and support 250 are provided for receiving the insert 225 for aseptically transferring of the fluid in/from the fluid container 1. For example, in an embodiment, after the cap 12 is connected to a fluid container 1 and the fluid is transferred into the fluid container 1, the fluid dispenser 14 is configured such that at least a downward directed force towards the fluid container 1 inserts the insert 225 into the support 250 of the cavity 245 and allows the disconnection of the insert 225 from the main body 205 of the fluid dispenser 14 to seal the fluid container, e.g., the insert 225 is press-fitted into the cap 12 without requiring additional equipment or change of the cap 12. It is appreciated that the insert 225 can also seal the cap 12 using other structures for engaging/disengaging the insert 225 for example, using a threaded connection system, engaging portions and recesses, bumps or protrusions, or the like.
The aseptic closure assembly 10 including the fluid dispenser 14 and the cap 12 can be made of a same material as or similar material to the materials of the fluid container 1 and/or each other or a combination thereof. In an embodiment, the fluid dispenser 14, including the main body 205, the shell housing 215, and the insert 225, and the cap 12 can be made of, for example, polyolefins such as, but not limited to, polypropylene, high-density polyethylene, linear low-density polyethylene, or the like. Other non-limiting example of polymers suitable for making various embodiments of the aseptic closure assembly 10, including the cap 12 and the fluid dispenser 14, include fluoropolymers, polyesters, polycarbonates and polyamides. It will be appreciated that the materials are examples and that the actual materials for the cap 12 and the fluid dispenser 14 can vary beyond the stated list within the principles of this disclosure or can be a blend of any of the above. In an embodiment, a material of the cap 12 is the same as a material of the fluid dispenser 14. In another embodiment, the material of the cap 12 can be different from the material of the fluid dispenser 14. In another embodiment, a material of the different components of the fluid dispenser 14, e.g., the main body 205, the shell housing 215, and the insert 225, can be made of the same material or different material, or combination thereof.
The seals 220, 255 can be an O-ring or gasket formed from, but not limited to, at least one of silicone, a fluoropolymer, ethylene-vinyl acetate (EVA), a thermoplastic, or other biocompatible flexible and/or compressible material for sealing that is relatively inert, e.g., does not leach or significantly absorb the pharmaceutical, chemical, or biological fluid, and non-reactive, or a combination thereof. The seals can also include quad-rings, or a thermoplastic material or other flexible and/or compressible material for sealing that is melt processed, for example, overmolded or insert molded, to fill grooves in the respective members with the thermoplastic or flexible material, and/or formed from any of the above materials.
The operation and connection/disconnection of the aseptic closure assembly 10 having the fluid dispenser 14 to the cap 12 will be discussed while referencing

Thus, the aseptic closure assembly 502 is configured to connect and disconnect from a fluid container for the aseptic transferring of fluids in a fluid container that can be used in temperatures as low as −85° C. It is appreciated that the aseptic closure assembly 502 can also be used at other temperatures, such as 0° C., room temperature, or the like, while maintaining the benefits of the present disclosure. Accordingly, the fluid container having the aseptic closure assembly 502, as discussed above, is configured to be stored at frozen temperatures (e.g., temperatures of less than 0° C. and lower). In an embodiment, the fluid container having the aseptic closure assembly 502 can also be heated back to ambient temperature without having any substantial deformation. Substantial deformation includes, for example, visible cracking in the material, a shrinkage or expansion relative to its original shape at ambient temperature that can interfere with the connection(s) or adversely affect sealing of said connection(s). Temperature retraction testing can be performed according to ASTM D1329, ISO 2921, or any other suitable testing methodology for determining suitable retraction properties of the material at temperatures that may be used. Brittleness testing can be performed according to ASTM D2137, ISO 28702, or any other suitable testing methodology for determining resistance to cracking at temperatures that may be used.
The cap 512 is connectable to the rigid opening of the fluid container to secure the cap 512 to the fluid container. The cap 512 can be connected to the fluid container by press fitting the cap 512 to the rigid opening or the cap 512 and the rigid opening can include mutually engaging threading. It is appreciated that the cap 512 can also be connected to the fluid container 1 in other manners, for example, using mechanical fasteners, such as, clamps, respective engagement features, or the like, or welding or bonding techniques, such as, heat bonding, impulse welding, laser welding, ultrasonic welding, or similar fusion bonding/melt welding techniques. In an embodiment, the cap 512 can be connected to the fluid container using a tamper evident connecting system. For example, the cap 512 having the tamper evident connection system can include inwardly biasing retaining arms that engage corresponding protrusions around the rigid opening of the fluid container which once pressed to a predetermined position on the rigid opening the cap 512 is not able to be easily removed from the fluid container without leaving visible indications of damage to the cap 512 and/or the fluid container. In another embodiment, the cap 512 having the tamper evident connection system can include a protrusion at a lower portion of the threading, so that once the cap 512 is threaded to a predetermined position, the cap 512 is not able to be removed from the fluid container 512, e.g., by reversing the rotation of the cap 512 on the rigid opening. In yet another embodiment, the tamper evident connection system can include a ring on the cap 512, which separates from the cap 512, if the cap 512 is removed from the fluid container. Thus, the tamper evident connection system is able to alert a customer or user of the fluid container having the cap 512 if the fluid container has been opened, or attempted to be opened, and possibly contaminated and/or compromised.
The cap 512 includes a housing 540, a cavity 545 within the housing 540, ports 570, and a set of seals 255. The housing 540 of the cap 512 includes second retaining features 560 that have complementary shapes with first retaining features 535 on the main body 505 and secondary body 508 of the fluid dispenser 514 for engaging the outer surface of the housing 540 of the cap 512. The first retaining features 535 are able to engage the second retaining features 560 for secure attachment of the fluid dispenser 514 to the cap 512 and to disengage for release of the fluid dispenser 514 from the cap 512. For example, in an embodiment, the second retaining features 560 can include pins or protrusions that engage respective slots formed by the first retaining features 535 on the main body 505 and secondary body 508 of the fluid dispenser 514. The insert 525 is configured to be engageable and disengageable with the port 570 so that a fluid communication channel is able to be opened and closed between the fluid container and the ports 570, as further discussed below. For example, in an embodiment, after the cap 512 is connected to a fluid container, the fluid dispenser 514 is configured to engage the insert 525 such that a downward directed force towards the fluid container and a rotation thereof connects the insert 525 onto the fluid dispenser 514 and allows the disconnection of the insert 525 from the port 570 to allow the main body 505 (and/or secondary body 508) of the fluid dispenser 514 to be inserted into the fluid container to aseptically transfer fluid to/from the fluid container. After the fluid has been transferred with the fluid container, it is appreciated that the insert 525 can be reengaged with the port 570 such that the insert 525 and the seal 555 seals the ports 570 from fluid communication with the fluid container.
For example, in an embodiment, as seen in
In another embodiment of the cap 512, as seen in
It is appreciated that while the cap 512 has been illustrated and shown as being separate pieces, such disclosure is not intended to be limiting. For example, the cap 512 can be constructed from ports that are connected to the housing, or the cap 512 can be constructed as a single molded piece or component. Different inserts can then be used to complement the engagement pieces of the fluid dispenser. It is also appreciated that the ports 570 can be a single port provided for the cap 512, in which the port 570 is configured to allow connection to two separate fluid lines in a fluid dispenser connected to the same.
Referring back to
The fluid lines 510 nearer the first end of the main body 505 and the secondary body 508 can include a tube connector for connecting to a fluid transfer system for the transfer, e.g., filling or removing, of the fluid with respect to the fluid container. The tube connector can be selected from the group consisting of a hose barb, an overmolded connection, a screw connection, a press-fit connection, a snap-fit connection, or a combination thereof. It is also appreciated that the tube connector can be continuously formed with the fluid transfer system, for example, by molding or overmolding the fluid dispenser with the fluid transfer system.
In an embodiment, the fluid dispenser 514 including the main body 505 and the secondary body 508 includes engagement pieces 507, for example, a protrusion that has a shape that matches the complementary engagement members 526, 726 (as illustrated in
The aseptic closure assembly 502 including the fluid dispenser 514 and the cap 512 can be made of a same material as or similar material to the materials of the container and/or each other or a combination thereof. In an embodiment, the fluid dispenser 514, including the main body 505, the secondary body 508, the shell housing 515, the secondary shell housing 509, and the insert 525, and the cap 512 can be made of, for example, polyolefins such as, but not limited to, polypropylene, high-density polyethylene, linear low-density polyethylene, or the like. Other non-limiting example of polymers suitable for making various embodiments of the aseptic closure assembly 502, including the cap 512 and the fluid dispenser 514, include fluoropolymers, polyesters, polycarbonates and polyamides. It will be appreciated that the materials are examples and that the actual materials for the cap 512 and the fluid dispenser 514 can vary beyond the stated list within the principles of this disclosure or can be a blend of any of the above. In an embodiment, a material of the cap 512 is the same as a material of the fluid dispenser 514. In another embodiment, the material of the cap 512 can be different from the material of the fluid dispenser 514. In another embodiment, a material of the different components of the fluid dispenser 514, e.g., the main body 505, the secondary body 508, the shell housing 515, the secondary shell housing 509, and the insert 525, can be made of the same material or different material, or combination thereof. In an embodiment, the shell housing 515 can be made from silicon or a flexible polymer to allow the compression and expansion of the shell housing.
The seals 520, 555 can be an O-ring or gasket formed from, but not limited to, at least one of silicone, a fluoropolymer, ethylene-vinyl acetate (EVA), a thermoplastic, or other biocompatible flexible and/or compressible material for sealing that is relatively inert, e.g., does not leach or significantly absorb the pharmaceutical or biological fluid, and non-reactive, or a combination thereof. The seals can also include quad-rings, or a thermoplastic material or other flexible and/or compressible material for sealing that is melt processed, for example, overmolded or insert molded, to fill grooves in the respective members with the thermoplastic or flexible material, and/or formed from any of the above materials.
The operation and connection/disconnection of the fluid dispenser 514 to the cap 512 will be discussed while referencing
For example, as seen in
After the fluid transfer process has been completed, the apertures 506 and insert 525 can be raised in an upward direction such that the apertures 506 are positioned between the seals 520 and the shell housing 515 and the insert 525 is engaged with the port 570 by rotation of the insert 525. It is appreciated that when the insert 525 is engaged with the port 570, the seal 555, which is provided along the inner periphery of the outer engagement pieces or members 527, and the insert 525 seal the port 570 from fluid communication with the fluid container 501. Upon a further rotation of the main body 505, the engagement pieces 507 on the main body 505 disengage with the complementary engagement members 526 of the insert 525. Accordingly, upon rotation of the fluid dispenser 514 so that the first retaining features 535 of the main body 505 of the fluid dispenser are disengaged with the second retaining feature 560 on the port 570 of the cap 512, the fluid dispenser 514 can be removed from the cap 512 and the fluid container 501. It is appreciated that since the insert 525 is only in contact with the fluid dispenser 514 for the transfer of fluid with the fluid container 501, the fluid handling system remains closed, since a secondary step is not required to seal the fluid container 501, e.g., replacing the aseptic closure assembly with a stopper or the like which makes the fluid handling system susceptible to contamination.

Upon a further rotation of the secondary body 508, the engagement pieces 507 on the secondary body 508 disengage with the complementary engagement members 526 of the insert 525. Accordingly, upon rotation of the secondary body 508 of the fluid dispenser 514 the first retaining features 535 of the secondary housing shell 509 are disengaged with the second retaining feature 560 on the cap 512, and the fluid dispenser 514 can be removed from the cap 512 and the fluid container 501. It is appreciated that since the insert 525 is only contacted with the fluid dispenser 514 for the transfer of fluid with the fluid container 501, the fluid handling system remains closed, since a secondary step is not required to close the fluid container 501, e.g., replacing the aseptic closure assembly with a stopper or the like which makes the fluid handling system susceptible to contamination.

As seen in
After the fluid transfer process has been completed, the apertures 1006 and insert 1025 can be rotated so that the spring 1080 biases the insert 1025 and in the closed position. The insert 1025 is engaged with the second port 1070 so that the seal 1055 and insert 1025 seal the port 1070 from fluid communication with the fluid container. Upon a further rotation of the secondary body 1008, the second shell housing 1009 is disengaged with the second port 1070 and the spring 1011 biases the sealing end 1013 towards the second end of the secondary body 1008 such that the apertures 1006 are positioned between the seal 1020 of the secondary body 1008 and the sealing end 1013. It is appreciated that since the insert 1025 is only contacted with the secondary body 1008 of the fluid dispenser for the transfer of fluid with the fluid container, the fluid handling system remains closed, since a secondary step is not required to close the fluid container, e.g., replacing the aseptic closure assembly with a stopper or the like which makes the fluid handling system susceptible to contamination.

The fluid container can then be stored, transported, and used during the manufacturing process. For example, in an embodiment, the fluid container can be frozen such that the transferred fluid in the fluid container is frozen to about −85° C. Then, the fluid container can be transported and the transferred fluid can be thawed at a temperature between about 1° C. and 10° C. to allow flowability of the fluid. The fluid dispenser 514 can then be used to aseptically connect and disconnect to the fluid container. For example, in an embodiment, the main body 505 of the fluid dispenser 14 can be rotated in the shell housing and the shell housing 515 can be compressed so that the fluid line 510 is aseptically inserted into the fluid container. When the secondary body 508 is attached to the cap 512, a vacuum system (or positive pressure) can be used to remove the fluid from the fluid container through the fluid line of the main body 508.
