ABSTRACT:
Pouring fluid without spilling from a container having a top opening into a fill hole in mechanical equipment is difficult because one can't position the top opening adjacent to the fill hole. A fill cap having a contained extension comprises: a) a base having a lower portion having an external diameter sized to snugly and securely mate within the fill hole; b) an upper head having an upper portion thereof having an external peripheral surface adapted to be gripped and twisted, and a lower portion thereof having a thread configured to mate with the threaded top opening in the base; and, c) a plurality of neck segments, each having a tapered top portion adapted to mate within an opening immediately thereabove, and a smaller rounded tapered bottom portion, said neck segments assembled between the upper head and the base so that when the upper head is unscrewed from within the base, and then pulled, the upper head is solidly and peripherally continuously connected by the neck segments to the base.
