Abstract

An aseptic closure assembly for a fluid container that includes a cap connectable to an opening of the fluid container and a fluid dispenser connectable to an outer surface of the housing of the cap. The fluid dispenser includes a main body and fluid lines provided within the main body, a shell housing provided around the main body, and an insert connectable to a 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. 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.

First claim

What is claimed is:

1. An aseptic closure assembly for a fluid container, comprising:
a cap connectable to an opening of the fluid container, the cap comprising 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, wherein the fluid dispenser comprises 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,
wherein 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, and
wherein 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.

2. The aseptic closure assembly according to claim 1 , wherein the fluid container is a bottle.

3. The aseptic closure assembly according to claim 1 , wherein the shell housing comprises an expanded portion that is in fluid communication with the apertures so that when a fluid is supplied or removed through the fluid lines of the fluid dispenser, the fluid flows from the apertures through the expanded portion and around the insert into the fluid container or from the fluid container around the insert through the expanded portion and then through the apertures.

4. The aseptic closure assembly according to claim 1 , wherein the insert is disconnected from the main body by a press-fit fitting into the cavity and the support and/or connected by a rotation of the fluid dispenser while the insert is fitted into the support of the cavity.

5. The aseptic closure assembly according to claim 4 , wherein the first set of seals comprises a first seal around the outer surface of the cap that is connectable to an inner surface of the shell housing and a second seal around the cavity.

6. The aseptic closure assembly according to claim 4 , wherein the fluid dispenser comprises engagement pieces for engaging the insert or an engagement member such that the fluid dispenser is able to engage the insert by the rotation of the fluid dispenser to remove the insert from the support of the cavity.

7. The aseptic closure assembly according to claim 1 , wherein the second set of seals comprises a third seal provided on the main body above the apertures and a fourth seal provided below the apertures along a length direction of the main body, wherein the third seal and the fourth seal engage the shell housing when the apertures are positioned above the expanded portion.

8. The aseptic closure assembly according to claim 1 , wherein the shell housing comprises a plurality of first retaining features extending from one end of the shell housing that are configured to engage second retaining features provided on the outer surface of the housing of the cap, wherein the first retaining feature and the second retaining feature having complementary shapes.

9. The aseptic closure assembly according to claim 1 , wherein the first set of seals and the second set of seals comprise one or more of silicone and ethylene-vinyl acetate (EVA).

10. The aseptic closure assembly according to claim 1 , wherein at least one of the cap or the insert comprises a fluoropolymer.

11. The aseptic closure assembly according to claim 1 , wherein the cap is connected to the fluid container using a tamper evident connector.

12. The aseptic closure assembly according to claim 1 , wherein the shell housing comprises a plurality of arms extending from one end of the shell housing that are configured to engage a corresponding plurality of slots provided on the outer surface of the housing of the cap, wherein the plurality of arms and the plurality of slots have complementary shapes for engaging and disengaging the same.

13. The aseptic closure assembly according to claim 1 , further comprising means for engaging and disengaging the fluid dispenser to the cap.

14. An aseptic closure assembly for a fluid container, comprising:
a cap connectable to an opening of the fluid container, the cap comprising a housing, a cavity within the housing, a port connected to the cavity, and a first set of seals,
wherein the port comprises a port shell and an insert connected to one end of the port shell, wherein 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, wherein the fluid dispenser comprises 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,
wherein 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.

15. The aseptic closure assembly for a fluid container according to claim 14 , wherein the cap comprises a second cavity and a second port connected to the second cavity, wherein the second port comprises a second shell, a second insert provided to seal one end of the second port, and a first spring that biases the second insert in a closed position.

16. The aseptic closure assembly for a fluid container according to claim 15 , further comprising a secondary body of the fluid dispenser having a second shell housing, a second spring that biases the secondary body in the second shell housing, and a third set of seals, wherein the second shell housing is configured to engage an outer surface of the second port so that the connection of the second shell housing to the second port causes the secondary body to bias the insert towards the fluid container to provide a second fluid communication channel between the secondary body and the fluid container.

17. The aseptic closure assembly for a fluid container according to claim 16 , wherein the second port further comprises a pipe connected to the second port configured to direct fluid to a side of the fluid container.

18. The aseptic closure assembly for a fluid container according to claim 17 , wherein the secondary body includes a tube connector 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.

19. The aseptic closure assembly for a fluid container according to claim 14 , wherein the shell housing comprises bellows that are compressible to allow the fluid line to be aseptically inserted into the fluid container.

20. A method for aseptically transferring a fluid into and from a fluid container comprising the steps of:
connecting a cap to an opening of the fluid container, the cap comprising a housing, a cavity within the housing, a port connected to the cavity, and a first set of seals, wherein the port comprises a port shell and an insert connected to one end of the port shell, wherein the insert is configured to open and close a fluid communication channel between the fluid container an
