Abstract

An applying material extruding container includes a leading tube and a pipe member inserted into the leading tube so as to be slidable in the axial line direction of the leading tube relative to the leading tube. In the initial state, the front end of the pipe member is located at a position displaced backward a predetermined distance from the front end of the leading tube, and the applying material is filled from in the pipe hole of the pipe member to in the tube hole of the leading tube. The inner surface of the region of the tube hole extends straight in the axial line direction. In the applying material extruding container, when the container main body and the control tube are relatively rotated in one/the other direction, by the screwing action of the first screw part, the pipe member is made to move forward/backward together with the applying material.

First claim

What is claimed is:

1. An applying material extruding container, comprising:
a screw part,
a leading tube forming a tubular shape and having an opening at a tip thereof, and
a pipe member inserted into the leading tube so as to be slidable in an axial line direction of the leading tube relative to the leading tube, wherein
in an initial state, a front end of the pipe member is located at a position displaced backward by a predetermined distance from a front end of the leading tube, wherein a pipe hole of the pipe member and a tube hole of the leading tube are adapted to be filled with an applying material;
wherein an entire inner surface of a region of the tube hole that is adapted to contact the applying material and slidably engages the pipe member extends straight in the axial line direction so as to be devoid of any step portions;
when a front section of the container and a rear section of the container are relatively rotated in one direction, a screwing action of the screw part is adapted to move the pipe member forward, together with the applying material, relative to the leading tube, and when further relatively rotated in the one direction, the screwing action of the screw part is adapted to move the applying material forward, relative to the leading tube and the pipe member; and
when the front section of the container and the rear section of the container are relatively rotated in another direction, the screwing action of the screw part is adapted to move the pipe member backward, together with the applying material, relative to the leading tube.

2. The applying material extruding container according to claim 1 , wherein the front end of the pipe member is located in forward limit thereof at approximately the same position as the front end of the leading tube.

3. The applying material extruding container according to claim 2 , wherein
the screw part comprises a first screw part and a second screw part; and
when the front section of the container and the rear section of the container are relatively rotated in the one direction, by the screwing action of the first screw part or the screwing action of the first and second screw parts, the pipe member is adapted to move forward, together with the applying material, relative to the leading tube, and when further relatively rotated in the one direction, the screwing action of the second screw part is adapted to move the applying material forward relative to the leading tube and the pipe member.

4. The applying material extruding container according to claim 1 , wherein
the screw part comprises a first screw part and a second screw part; and
when the front section of the container and the rear section of the container are relatively rotated in the one direction, by the screwing action of the first screw part or the screwing action of the first and second screw parts, the pipe member is adapted to move forward, together with the applying material, relative to the leading tube, and when further relatively rotated in the one direction, the screwing action of the second screw part is adapted to move the applying material forward relative to the leading tube and the pipe member.
