ABSTRACT:
A cosmetic pencil for dispensing a soft cosmetic mass having a push rod with an extended head. The cosmetic pencil has a barrel and a hollow sheath is rotatingly held by the barrel. A threaded push rod is keyed so that it turns with the barrel and the sheath has threads near the base of its inner end and as the sheath and barrel are turned with respect to each other the push rod moves outwardly out of the barrel and pushes the cosmetic mass out of the sheath. The head on the threaded push rod is enlarged and may be inserted downstream of the threaded portion of the sheath by a slot and a half thread which permits the widened portion of the push rod to be snapped in front of the threads so that it does not interfere with the threads. The threaded push rod may also have a separate piston snapped thereon. Also the sheath is provided with one way pawls which snap in and out of the grooves on the inside surface of the barrel indicating that the sheath and barrel are being turned with respect to one another.
