| 1. A coupler connecting a fluid reservoir and a processing apparatus comprising:
a first longitudinally extending cylindrical ring defining an interior area;
a second cylindrical ring longitudinally adjacent the first cylindrical ring; and
a longitudinally extending fluid conduit positioned within the interior area of the first cylindrical ring and through a laterally
extending wall into the second cylindrical ring, the fluid conduit defining a fluid flow aperture,
wherein the laterally extending wall is positioned between the first cylindrical ring and the second cylindrical ring, the
laterally extending wall having a top surface directed towards the processing apparatus and defining at least one vent aperture
creating fluid venting communication between the fluid reservoir and the top surface.
