A container coupler for either transferring viscous fluids or holding a vessel upside down includes an engaging portion for encircling the mouth of a lower vessel and an aperture for engaging an upper vessel. A conical surface surrounding the aperture causes fluid spilled on the coupler to travel to the aperture ami into the lower vessel. With the upper vessel engaged on the coupler, a portion of the upper vessel is disposed below the mouth of, and within the lower vessel to add stability, prevent leakage and decrease the height of the stacked vessels. |
