发明名称 Pipe cover and holder
摘要 A pipe holder and bowl cover for a smoker's pipe is comprised of a spherical mass of open-celled spongy plastic foam with a bowl receiving bore provided therein and dimensioned to frictionally secure the bowl cover to the bowl of the pipe. A retaining screen is mounted within the bore so as to contact the upper rim of the pipe bowl when the bowl cover is secured to the bowl thereby preventing the escape of a tobacco or like substance that is placed in the bowl.
