Abstract

At a distal end of a pipe member 4 , a plurality of projections 4 n are disposed circumferentially. The projection 4 n extends frontward in an axial direction. At a tip end of a leading tube 3 , a groove forming section G is disposed. The groove forming section G includes a plurality of grooves 3 n circumferentially in an inner peripheral surface. The grooves 3 n extend in the axial direction. The projection 4 n of the pipe member 4 enters the groove 3 n . At the leading tube 3 , an inner diameter of a convex part 3 p between the grooves 3 n and 3 n circumferentially arranged and an inner diameter of a pipe part that houses the projection 4 n of the pipe member 4 and the stick-like material rearward with respect to this projection 4 n of the pipe member are identical size.

First claim

What is claimed is:

1. A stick-like material feeding container, comprising:
a leading tube that has an opening at a distal end, the leading tube having a first female screw in an inner peripheral surface;
a container main body to which the leading tube is mounted to be relatively rotatable;
a pipe member disposed in the leading tube, a stick-like material being filled into a pipe part of the pipe member;
a movable body that includes a piston and a shaft part, the piston being movable in the pipe member to extrude the stick-like material, the shaft part having a second male screw at an outer peripheral surface; and
a screw member that includes a first male screw at an outer peripheral surface and a second female screw at an inner peripheral surface, the first male screw being screwed with the first female screw of the leading tube to constitute a first screw part, the second female screw being screwed with the second male screw of the movable body to constitute a second screw part, wherein
a relative rotation of the leading tube and the container main body advances or retreats the screw member together with the pipe member by a screwing action by the first screw part,
meanwhile, when the screw member and the pipe member advance for a predetermined distance, a screwing action by the second screw part advances the movable body to extrude the stick-like material to ensure projecting the stick-like material from the opening of the leading tube,
at a distal end of the pipe member, a plurality of projections are disposed circumferentially, the plurality of projections extending frontward in an axial direction,
at a tip end of the leading tube, a groove forming section is disposed, the groove forming section including a plurality of grooves circumferentially in an inner peripheral surface, the plurality of grooves extending in an axial direction, each of the plurality of projections of the pipe member respectively entering one of the plurality of grooves,
an inner diameter of a convex part between the plurality of grooves circumferentially arranged at the tip end of the leading tube, an inner diameter of the plurality of projections at the distal end of the pipe member, and an inner diameter of a pipe part that houses the stick-like material rearward with respect to the plurality of projections of the pipe member are identical size, and
the screwing action by the first screw part advances or retreats a distal end of the plurality of projections of the pipe member within the groove forming section.
