ABSTRACT:
Disclosed herein is a one piece spill proof plug which allows a container to be inverted prior to dispensing a fluid to a receiving receptacle. The plug has a plug member, stem and V-shaped retainer members which allow the plug member to snugly fit into the neck portion of a container and allows the biased retainer members to expand within the container. The one piece spill proof plug has many applications, particularly for dispensing motor oil to an engine by way of a valve cover opening.
