Applying filler extruding container

1. An applying filler extruding container comprising:

a main body;

a leading tube installed in a leading end side of the main body so as to be relatively rotatable; and

a filling member which moves forward into the leading tube, has an inner portion formed as a filling region in which the applying filler is filled, has a discharge port in a leading end portion and is provided with an applying portion for applying said applying filler discharged through said discharge port to an applied portion,

wherein, when said main body and said leading tube are relatively rotated in one direction, meshing operation of a first meshing portion works and thereby said filling member moves forward, and when they are relatively rotated further in said one direction, meshing operation of a second meshing portion instead of said first meshing portion works and thereby said applying filler is discharged from said discharge port of said filling member, and

wherein, when said main body and said leading tube are relatively rotated in the other direction corresponding to an opposite direction to said one direction, meshing operation of said first meshing portion works and thereby said filling member moves backward.

2. The applying filler extruding container as claimed in claim 1 , wherein the applying filler extruding container is

provided with a movable body moving forward and thereby extruding said applying filler in said filling region toward said discharge port,

wherein the first meshing portion works first a meshing operation when said main body and said leading tube are relatively rotated in a feeding direction corresponding to said one direction and a feed-back direction corresponding to said other direction and thereby moves forward and backward said filling member including said movable body, and the meshing operation is stopped when said filling member reaches a forward limit, and

wherein the second meshing portion works the meshing operation when said main body and said leading tube are relatively rotated further in the feeding direction corresponding to said one diction in a state that said filling member reaches the forward limit and the meshing operation of said first meshing portion stops and thereby moves forward said movable body.

3. The applying filler extruding container as claimed in claim 2 , wherein the meshing operation of said first meshing portion works before the meshing operation of said second meshing portion by increasing an actuation resistance of said second meshing portion in comparison with an actuation resistance of said first meshing portion.

4. The applying filler extruding container as claimed in claim 3 , wherein the applying filler extruding container is provided with an elastic portion applying an elastic force to said second meshing portion, and

wherein the actuation resistance of said second meshing portion is increased by utilizing the elastic force of the elastic portion.

5. The applying filler extruding container as claimed in claim 4 , wherein said elastic portion is constituted by a ring-shaped elastic body installed to an outer peripheral side of a female thread constituting said second meshing portion.

6. The applying filler extruding container as claimed in claim 2 , wherein the applying filler extruding container is provided with a click engagement portion which is click engaged in correspondence to the relative rotation between said main body and said leading tube at a time when the meshing operation by said second meshing portion works.

7. The applying filler extruding container as claimed in claim 6 , wherein said click engagement portion constituted by a ratchet mechanism which regulates the relative rotation in the feed-back direction between said main body and said leading tube at a time when the meshing operation by said second meshing portion works, and allows only the relative rotation in the feeding direction.

8. The applying filler extruding container as claimed in claim 2 , wherein said first meshing portion is structured such that when said main body and said leading tube are relatively rotated in the feed-back direction and said filling member including said movable body moves backward on the basis of the first worked meshing operation of said first meshing portion so as to reach a predetermined position at which said applying portion is accommodated within said leading tube, the meshing is cancelled and the first meshing portion idly rotates said main body and said leading tube so that the meshing operation of said second meshing portion does not work, and

wherein the meshing of said first meshing portion returns when said main body and said leading tube are relatively rotated in said feeding direction in a state that the meshing is cancelled.

9. The applying filler extruding container as claimed in claim 2 , wherein the applying filler extruding container is provided with a leading tube pressing member which is accommodated within said main body and comprises a spring portion capable of expanding and contracting in an axial direction, and

wherein said leading tube is installed to said main body via said leading tube pressing member so as to be relatively rotatable in a state of being energized to a rear side by the spring portion of said leading tube pressing member.

10. The applying filler extruding container as claimed in claim 9 , wherein said first meshing portion is structured such that the meshing operation is stopped when said main body and said leading tube are relatively rotated in the feed-back direction, said filling member including said movable body moves backward on the basis of the first worked meshing operation of said first meshing portion and said applying portion reaches the backward limit to be accommodated within said leading tube, and

wherein said second meshing portion is structured such that the meshing operation works so as to move backward said movable body when said filling member reaches the backward limit and said main body and said leading tube are relatively rotated further in the feed-back direction in a state that the meshing operation of said first meshing portion is stopped.

11. The applying filler extruding container as claimed in claim 10 , wherein a lead of said first meshing portion is made larger in comparison with a lead of said second meshing portion.

12. The applying filler extruding container as claimed in claim 2 , wherein said first meshing portion is structured such that the meshing operation is stopped when said main body and said leading tube are relatively rotated in the feed-back direction, said filling member including said movable body moves backward on the basis of the first worked meshing operation of said first meshing portion and said applying portion reaches the backward limit to be accommodated within said leading tube, and

wherein said second meshing portion is structured such that the meshing operation works so as to move backward said movable body when said filling member reaches the backward limit and said main body and said leading tube are relatively rotated further in the feed-back direction in a state that the meshing operation of said first meshing portion is stopped.

13. The applying filler extruding container as claimed in claim 12 , wherein a lead of said first meshing portion is made larger in comparison with a lead of said second meshing portion.

14. The applying filler extruding container as claimed in claim 2 , wherein a lead of said first meshing portion is made larger in comparison with a lead of said second meshing portion.
