Stick-shaped Material Propelling Container

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.

主权项

1. A stick-shaped material propelling container comprising:
an outer barrel opened at least at a tip end portion thereof and having a spiral groove formed in an inner peripheral surface thereof; a guide tube opened at least at a tip end portion thereof and having a peripheral wall and a plurality of axially extending guide slits formed in the peripheral wall; the guide tube being inserted in the outer barrel so as to be rotatable relative to the outer barrel and unmovable in an axial direction of the outer barrel; and a holding member for holding a stick-shaped material; the holding member comprising a bottom plate, on which the stick-shaped material is carried, a plurality of side plates for interposingly holding the stick-shaped material carried on the bottom plate, the plurality of side plates extending in a forward/rearward direction from side edge regions of the bottom plate, and engaging protrusions protruding laterally from rear end portions of the side plates with respect to the bottom plate; the holding member being slidably inserted in the guide tube in a state where the side plates or the engaging protrusions of the holding member are engaged with the guide slits of the guide tube, and the engaging protrusions of the holding member are engaged with the spiral groove of the outer barrel through the guide slits of the guide tube; and the holding member being adapted to be moved in the forward/rearward direction along the guide slits of the guide tube while being rotated relative to the outer barrel with the engaging protrusions being slid along the spiral groove of the outer barrel, by relative rotation of the outer barrel and the guide tube; wherein the spiral groove has a structure for causing rear end portions of the side plates of the holding member to come closer to each other in a radial direction of the outer barrel and for causing tip end portions of the side plates of the holding member to be separated radially outward from each other according to the mutually approaching movements of the rear end portions of the side plates of the holding member, when the engaging protrusions of the holding member are slid along a tip end portion of the spiral groove according to the relative rotation of the outer barrel and the guide tube.
