Abstract

A dip tube assembly having a tubular portion and a coupler portion, the coupler configured for removable coupling with the mouth of a container storing contents therein. The coupler portion comprises a first end for connection with a tubular portion; a second end for connection with a connector assembly, wherein the connector assembly provides a pressure to the container; an outer surface and an inner surface with a thickness therebetween, wherein the inner surface defines a lumen that allows the chemical fluid to be conveyed from the chamber through the tubular portion to the connector assembly; and at least one pressure relief feature on the outer surface.

First claim

1 . A coupler portion for a dip tube assembly for a container with a liner defining a chamber for a chemical fluid, the coupler portion comprising:
a first end for connection with a connector assembly for supplying a pressure to said container; a second end for connection with a tubular portion; and an outer surface and an inner surface with a thickness therebetween, wherein said inner surface defines a lumen for conveying a chemical fluid from said tubular portion to said connector assembly, said coupler portion defining at least one pressure relief feature.

2 . The coupler portion of claim 1 , wherein said at least one pressure relief feature comprises a pressure relief port.

3 . The coupler portion of claim 2 , wherein said pressure relief port defines a through hole extending through said thickness.

4 . The coupler portion of claim 2 , wherein said pressure relief port defines a first opening on said outer surface, a second opening on said inner surface, and a channel connecting said first opening and said second opening.

5 . The coupler portion of claim 1 , wherein said coupler portion includes a frustoconical portion between said second end and said first end.

6 . The coupler portion of claim 5 , wherein said at least one pressure relief feature comprises a pressure relief port that extending through said thickness, said pressure relief port being disposed between said first end and said frustoconical portion.

7 . The coupler portion of claim 5 , wherein said frustoconical portion defines a plurality of channel-like features defined by ribs that extend axially.

8 . The coupler portion of claim 1 , wherein an external diameter of said first end is greater than an external diameter of said second end.

9 . The coupler portion of claim 1 , further comprising a retaining feature proximate said first end for a sealing mechanism.

10 . The coupler of claim 9 , wherein said sealing mechanism is an O-ring.

11 . The coupler portion of claim 1 , wherein the at least one pressure relief feature is defined on the outer surface.

12 . The coupler portion of claim 11 , wherein said at least one pressure relief feature comprises an axial channel defined by axially extending ribs.

13 . The coupler portion of claim 12 , defining an annular channel proximate said first end.

14 . The coupler portion of claim 13 , defining a first notch that passes from said annular channel through said first end.

15 . The coupler portion of claim 14 , wherein said notch and said axial channel are axially aligned.

16 . The coupler portion of claim 14 , defining a second notch that passes from said annular channel into said axial channel.

17 . The coupler of claim 1 , wherein said at least one pressure relief feature comprises a lip portion at said first end of the coupler portion.

18 . The coupler of claim 1 , wherein said lip portion is frustoconical in shape.

19 . A dispensing system, comprising:
an overpack; a liner disposed in said overpack; a fitment portion operatively coupled to a mouth of said liner; a coupler portion, including: a lower end for connection with a tubular portion; an upper end for connection with a connector assembly, wherein said connector assembly provides a pressure to said container; and an outer surface and an inner surface with a thickness therebetween, wherein said inner surface defines a lumen for conveying a chemical fluid from said tubular portion to said connector assembly, said coupler portion defining at least one pressure relief feature.

20 - 21 . (canceled)

22 . The dispensing system of claim 19 , wherein:
said coupler portion is configured for receiving a connector for selective insertion into said coupler portion, said connector closing said pressure relief port when inserted in said coupler portion; said at least one pressure relief feature comprises a pressure relief port extending through said thickness; and said connector includes a probe that covers said pressure relief port for said closing of said pressure relief port when inserted in said coupler portion.

23 . The dispensing system of claim 22 , wherein said coupler portion further comprises a retaining feature proximate said upper end that retains a sealing mechanism, said sealing mechanism being seated against an inner surface of said fitment portion.

24 - 27 . (canceled)
