Abstract

The present disclosure relates to novel and advantageous closure/connector assemblies for use with a dispense assembly. The closure/connector includes a closure body as well as a cap seat adaptor for operable connection to the closure body. The cap seat adapter has a proximal end and a distal end and is configured for fluid communication with a source of material to be dispensed. The closure/connector also has a cap for connection to the distal end of the cap seat adaptor. A pressurizing gas inlet fitting adapted for connection to a pressure source is also included as a part of the closure/connector. The closure/connector assembly, in conjunction with the dispense assembly, is configured for the secure transport and dispense of the material to be dispensed.

Claims

1. A closure/connector assembly for use with a dispense assembly, the closure/connector comprising:

a closure body;

a cap seat adaptor for operable connection to the closure body, the cap seat adapter having a proximal end and a distal end and configured for fluid communication with a source of material to be dispensed;

a cap for connection to the distal end of the cap seat adaptor; and

a pressurizing gas inlet fitting adapted for connection to a pressure source;

wherein the closure/connector assembly, in conjunction with the dispense assembly, is configured for the secure transport and dispense of the material to be dispensed.

2. The closure/connector assembly of claim 1, wherein the closure body is made of polypropylene.

3. The closure/connector assembly of claim 1, further configured for a disposable, one-time use.

4. The closure/connector assembly of claim 1, wherein the cap seat adaptor further comprises a feature for reducing choke-off.

5. The closure/connector assembly of claim 4, wherein the feature for reducing choke-off comprises at least one channel positioned at the proximal end of the cap seat adaptor.

6. The closure/connector assembly of claim 3, wherein the closure/connector is configured for pressure dispensing the material to be dispensed.

7. The closure/connector assembly of claim 3, wherein the closure/connector is configured for pump dispensing the material to be dispensed.

8. The closure/connector assembly of claim 7, wherein the cap seat adaptor further comprises a dip tube extending into an interior of the dispense assembly.

9. The closure/connector assembly of claim 7, wherein the pressurizing gas inlet fitting is configured for utilization as a vent during dispense.

10. The closure/connector assembly of claim 1, wherein the cap is configured for a locking connection to the cap seat adapter.

11. A dispense assembly, comprising:

a liner for holding a material to be dispensed;

an overpack having the liner disposed therein;

a closure/connector assembly secured to the liner and overpack, the closure/connector comprising;

a closure body;

a cap seat adaptor for operable connection to the closure body, the cap seat adapter having a proximal end and a distal end and configured for fluid communication with a source of material to be dispensed;

a cap for connection to the distal end of the cap seat adaptor; and

a pressurizing gas inlet fitting adapted for connection to a pressure source;

wherein the closure/connector assembly, in conjunction with the liner and overpack, is configured for the secure transport and dispense of the material to be dispensed.

12. The dispense assembly of claim 11, wherein the closure/connector is configured for pressure dispensing the material to be dispensed.

13. The dispense assembly of claim 12, wherein the cap seat adapter comprises at least one channel positioned at the proximal end of the cap seat adaptor.

14. The dispense assembly of claim 11, wherein the closure/connector is configured for pump dispensing the material to be dispensed.

15. The dispense assembly of claim 14, wherein the cap seat adaptor further comprises a dip tube extending into an interior of the liner and in fluid communication with the material to be dispensed.

16. The dispense assembly of claim 11, further comprising a shipping ring detachably coupled to the dispense assembly to protect the closure/connector assembly during at least one of storage or transport.

17. The dispense assembly of claim 11, further comprising a shipping container for positioning the liner and overpack therewithin.

18. A method for storing, shipping, and dispensing the contents of a dispense assembly, the method comprising:

filling the dispense assembly with a desired material;

securing a closure/connector to the dispense assembly, the closure/connector comprising;

a closure body;

a cap seat adaptor for operable connection to the closure body, the cap seat adapter having a proximal end and a distal end and configured for fluid communication with a source of material to be dispensed;

a cap for connection to the distal end of the cap seat adaptor; and

a pressurizing gas inlet fitting adapted for connection to a pressure source;

wherein the closure/connector assembly, in conjunction with the dispense assembly, is configured for the secure transport and dispense of the material to be dispensed, such that the material to be dispensed may be dispensed by removing the cap and connecting a liquid dispense outfitting to the distal end of the cap seat adaptor.

19. The method of claim 18, wherein the closure/connector is configured for pressure dispensing the material to be dispensed.

20. The method of claim 19, wherein the closure/connector assembly is further configured for connecting a pressure in-line to the pressurizing gas inlet fitting prior to pressure dispense.

21. The method of claim 18, wherein the closure/connector is configured for pump dispensing the material to be dispensed.
