Stopple, stop′l, n. that which stops or closes the mouth of a vessel: a cork or plug.

A wasteful cock is a cock or pipe with a turning stopple running to waste.

You may at first stop it so, that the strong working may throw out the stopple, and yet keep it close, till it work strongly.

On examining it in full light he found the upper end, looking like a carved handle, to be a closing stopple removable by a turn.

He pounces upon the decanter, pulls out the stopple, and applies his nose to the mouth.
