The cutting element includes a rounded step to facilitate removal of the can after emptying. An orientation device is provided to orient the base with respect to the oil input to facilitate easy access to the cutting element. In the preferred embodiment, the orientation device comprises a downwardly biased sprocketed flange which engages a protrusion extending upwardly from the bottom of the base.

Abstract: A gasketless, dripless dispensing spout useful with canned oil or such liquids, is made of two pieces, namely a metallic tubular member with a cutter blade on one end and a surrounding plastic guide-reservoir tubing which is mated thereto such as by indented matching corrugations in facing surfaces. The reservoir serves by means of apertures through the spout member to receive any oil seepage on the can top and dispense it when pouring out the oil through the spout. Also it serves to channel oil about the spout back into the can by gravity flow when it is upright, thereby to avoid drip. The plastic reservoir contacts the flat surface of the can top flush in an arcuate pattern to discourage any leakage.
