摘要： A stick-shaped material propelling container is disclosed which comprises a barrel having a spiral groove formed in its inner peripheral surface, a guide tube having slits and inserted in the barrel so as to be rotatable relative to the barrel and axially unmovable, and a stick-shaped material holding member provided with side plates and protrusions and slidably inserted in the tube with the protrusions being engaged with the grooves through the slits. The groove has a structure for causing rear end portions of the side plates to come closer to each other and for causing tip end portions of the side plates to be separated radially outward from each other according to the mutually approaching movements of the rear end portions of the side plates, when the protrusions are slid along a tip end portion of the groove according to relative rotation of the barrel and the tube.
