ABSTRACT:
A bar extruding implement extrudes a bar, such as a lead, a lipstick or the like, gradually and is capable of automatically ejecting a marginal portion of the bar. A projection formed on a sliding member inserted in an inner tube slides along a helical groove formed in the inner circumference of a barrel to advance the sliding member when a rotational operating head is turned to turn the inner tube in one direction, whereby a bar holder holding a bar is advanced gradually toward the front end of the barrel to extrude the bar from the front end of the barrel. Upon the arrival of the bar holder at a disengaging position, the sliding member is disengaged from the bar holder and advances forward through the bar holder when the inner tube is turned further after the bar holder has arrived at the disengaging position to eject a marginal portion of the bar remaining on the bar holder.
