Bag in box cleanable connector system
A system and method for connecting a fluid within a product container such as a bag to a product dispenser. The system and method, more particularly, discloses a cleanable connector system for a Bag-In-Box (“BIB”) type package having a valve arrangement that prevents the mixing of product within the bag and in the line. Various embodiments provide a connector system including a valve arrangement having a line-side valve and a bag-side valve, wherein the valve arrangement allows connection to a bag and to a line-side connector while preventing the product within the bag and in the line from mixing. The system and method improves the shelf life of products contained within the bag and reduces the risk of contamination of the bag, the line, and the product contained within the bag by minimizing the risk of introducing biological and other foreign material into the system when connecting the bag and the line.
1. A product dispenser connector system, comprising:
a bag connector, comprising:
a body member having at least one attachment structure;
at least one annular collar disposed within the body member, wherein the at least one annular collar is arranged and configured to engage a line connector;
an elastomeric membrane disposed within the at least one annular collar, wherein the elastomeric membrane includes at least one slit, wherein the elastomeric membrane includes a substantially cup-shaped structure;
at least one actuation member disposed within the at least one annular collar; and,
a bag interface, wherein the bag interface is arranged and configured to fittingly engage a gland; and
the line connector, comprising:
a body member having at least one attachment structure;
at least one annular collar disposed within the body member, wherein the at least one annular collar is configured and arranged to engage the bag connector;
a cylindrical member surrounded by the at least one annular collar, the cylindrical member having an opening formed therein, wherein the cylindrical member fittingly engages the cup-shaped elastomeric to form a seal between the at least one annular collar of the bag connector and the cylindrical member;
a plunger disposed within the cylindrical member;
a resilient member in communication with the plunger, wherein the resilient member urges the plunger towards the opening in the cylindrical member; and
a boot substantially surrounding at least an end of the plunger;
wherein the bag connector and the line connector fittingly engage to be in fluid communication with each other.
2. The system according to claim 1 , wherein the gland stores a product to be dispensed.
3. The system according to claim 2 , wherein the product to be dispensed is a fluid.
4. The system according to claim 1 , wherein the at least one attachment structure of the bag connector includes an attachment lip that engages a corresponding structure of the line connector.
5. The system according to claim 1 , wherein the at least one actuation member of the bag connector is arranged and configured to depress the plunger of the line connector.
6. The system according to claim 1 , wherein the line connector is arranged and configured to dispense a product received via the bag connector.
7. The system according to claim 6 , wherein the product to be dispensed is a fluid.
8. The system according to claim 1 , wherein the at least one attachment structure of the line connector includes an attachment lip that engages a corresponding structure of the bag connector.
9. The system according to claim 1 , wherein the plunger of the line connector is substantially cylindrical.
10. The system according to claim 1 , wherein the resilient member of the line connector comprises a spring.
11. The system according to claim 1 , wherein the boot of the line connector comprises an elastomeric material.
