Abstract

A fluid delivery system includes a flexible media bag having an outlet spout projecting therefrom. A passageway longitudinally extends through the outlet spout and communicates with the interior of the media bag. A diptube connector is mounted to the outlet spout. The diptube connector includes a stem having a first end with a barb radially projecting out therefrom and an opposing second end with an annular flange radially projecting out therefrom. The flange has an outer diameter greater than the inner diameter of the passageway in the outlet spout. The first end of the diptube connector is received in sealed engagement within the first end of the diptube. The second end of the diptube is passed through the passageway in the outlet spout such that the flange on the diptube connector rests on the outlet spout. The outlet spout having the diptube connector mounted thereon is received in sealed engagement within a delivery tube.

(d) means removably mounted to the outlet spout for securing the first end of the diptube within the passageway of the outlet spout so as to enable fluid to pass through the diptube and out the outlet spout.

10. A fluid delivery system as recited in claim 9, wherein the container comprises a flexible media bag.

11. A fluid delivery system as recited in claim 9, further comprising an annular barb radially outwardly projecting from the first end of the outlet spout.

12. A fluid delivery system as recited in claim 9, wherein the means for securing comprises a stem having a channel extending between a first end and an opposing second end, the first end of the stem being configured to be received within the first end of the diptube, the second end of the stem having a flange outwardly projecting therefrom, the flange having an outer diameter larger than the inner diameter of the passageway in the outlet spout.

13. A fluid delivery system as recited in claim 12, wherein the flange is annular.

14. A fluid delivery system as recited in claim 12, wherein the flange comprises:

(a) a primary plate having an outer diameter larger than the inner diameter of the passageway; and

(b) a secondary plate mounted against the primary plate and having an outer diameter complementary to the inner diameter of the passageway in the outlet spout.

15. A fluid delivery system as recited in claim 9, further comprising an annular port plate radially outwardly projecting from the second end of the outlet spout.

16. A fluid delivery system as recited in claim 9, further comprising a flexible delivery tube having an end received over the first end of the outlet spout, the delivery tube having an inner diameter smaller than the outer diameter of the flange on the diptube connector.

17. A fluid delivery system comprising:

(a) a collapsible bag having an interior compartment;

(b) a tubular outlet spout having a free first end, an opposing second end, and an interior surface bounding a passageway extending therebetween, the second end of the outlet spout being attached to the bag such that the passageway communicates with the interior compartment thereof;

(c) a diptube having a first end, an opposing second end, and a fluid path extending therebetween, the first end being disposed within the passageway of the outlet spout, the second end being in fluid communication with the compartment of the collapsible bag, the fluid path of the diptube being open such that when fluid is disposed within the compartment of the collapsible bag, the fluid can travel through the fluid path from the second end of the diptube to the first end of the diptube; and

(d) a diptube connector comprising a tubular stem having a first end, an opposing second end, and a channel extending therebetween, the first end of the diptube connector being removably received within the first end of the diptube when the first end of the diptube is received within the passageway of the outlet spout, the second end of the stem having a flange radially outwardly extending therefrom, the flange having an outer diameter greater than the inner diameter of the passageway at the first end of the outlet spout.
