Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a rod-like material feeding container which can feed out a rod-like material such as a rubber eraser, a crayon, a pass, a core, etc. from a preceding tool.

[Conventional technology and its problems]

In the conventional rod-shaped material feeding container, the chuck and the inner cylinder fitted to the chuck ring by the rear end knock advance or retreat by the spring force against the spring, and the chuck opens and closes, and the rod-shaped object is fixed by the chuck. It is configured to be fed out by length and to be fed out by a predetermined length from the tip of the tool. However, when the tool is removed from the outer tube, the internal chuck ring, spring, inner tube with chuck, etc. come off, and the parts to be handled There is a problem that the number of points increases correspondingly and disassembly and assembly are not easy.

[Means for solving the problem]

In order to solve the above-mentioned problem, the container according to the present invention locks the inner ring 5 having the chuck 4 at the tip thereof fitted with the chuck ring 3 as shown in FIG. And a rod-shaped material feeding mechanism configured by disposing an elastic body 6 between the tip tool 2 and the inner cylinder 5 is inserted into the outer cylinder 1, and The tool 2 is configured to be detachably attached to the distal end of the outer cylinder 5.

[Action]

When the inner cylinder 5 is knocked, the chuck 4 connected to the inner cylinder 5 and fitted in the chuck ring 3 advances or retreats against the elastic body 6 or by the elastic force of the elastic body 6, so that the rod-shaped object 7 is chucked. 4 and a predetermined length from the leading tool 2.

When the tool 2 is removed from the outer cylinder 1, the chuck ring 3 locked to the tool 2, the chuck 4 fitted in the chuck ring 3, the inner cylinder 5 connected to the chuck 4, Elastic body 6 for urging cylinder 5 backward, tip 2 and chuck 4
Since the rod 7 and the like, which are inserted and held, are integrally connected to the leading tool 2 to form a rod feeding mechanism which is an integrated part, the rod 7 can be handled as two parts of the integrated part and the outer cylinder 1. And the number of parts can be reduced to two parts.
Disassembly and assembly are relatively easy.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing the configuration of a first embodiment of the container of the present invention. In the first embodiment, a tip 2 having a tapered and gentle conical shape is detachably attached to the tip of an outer cylinder 1. It is screwed. The attachment and detachment of the tool 2 is not limited to screwing,
Any means can be used as long as it can be attached or detached by attachment or the like. The engaging projection 16 of the chuck ring 3
15 is fitted therein, and a chuck 4 is fitted in the chuck ring 3, and the chuck 4 is connected to the inner cylinder 5.

The chuck ring 3 in which the locking projection 15 is fitted to the chuck 16, the chuck 4 fitted in the chuck ring 3, the chuck 4
, A spring 6 for urging the inner cylinder 5 rearward,
Bar-shaped eraser 7 inserted and held by tip 2 and chuck 4
And the like are integrally connected to the leading tool 2 to form a rod-shaped object feeding mechanism which is an integrated component.
, The number of parts can be reduced to two parts, and disassembly and assembly are relatively easy.

FIG. 2 is a longitudinal sectional view of a main part of a second embodiment. This second embodiment is a spaceless conical member whose tip is sharply narrowed as the tip 2 in the first embodiment of FIG. This is an example in which the spring 6 is provided between the receiving portion 13 of the preceding tool 2 and the front end of the chuck 4 and the spaceless conical leading tool 2 whose tip sharply narrows is used. The loss of the rod-shaped eraser 7 can be reduced.

FIG. 3 is a longitudinal sectional view of a main part of the third embodiment. In the third embodiment, an inwardly protruding portion 8 is provided at an extension of the chuck ring 3 in the first embodiment of FIG. In this example, the protrusion 8 is inserted into the cut 9 of the chuck 4.
Thus, the opening and closing of the chuck 4 can be more reliably performed.

FIG. 4 is a longitudinal sectional view of a main part of the fourth embodiment. In the fourth embodiment, a locking portion 10 is provided on the outer peripheral surface of the front part of the chuck 4 in the first embodiment of FIG. This is an example in which the stopper 10 is locked to an inner step 11 provided at a position opposed to the chuck ring 3, the chuck 4 is securely closed in the locked state, and the chuck 4 is forcibly moved when the chuck ring 3 advances. The chuck 4 is opened after the chuck ring 3 hits the tool 2 with the rod-shaped eraser 7 securely closed. Therefore, the feeding of the rod-shaped eraser 7 is smoothly and reliably performed.

FIG. 5 is a longitudinal sectional view showing the structure of the fifth embodiment. In the fifth embodiment, a projection 14 is provided on the outer surface of the front part of the inner cylinder 5,
The protrusion 14 is fitted to the engaging portion 17 of the tool 2, and the front surface of the locking protrusion 15 of the chuck ring 3 locked to the locking surface 16 b of the engaging portion 16 of the tool 2. 2, a dimension A between the front end 16c of the engagement part 16 and a dimension B between a front end of the inner cylinder 5 fitted to the tip 2 and the rear surface of the chuck ring 3, and an engagement part of the tip 2 The relationship between the projection surface 17a of the projection 14 of the inner cylinder 5 fitted to 17 and the dimension C between the engagement portion 17 and the front end 17b of the tool 2 is C> A + B,
In addition, the dimensions are determined so that B> A. Reference numeral 18 denotes a receiving portion provided on the inner cylinder 5.

With such a configuration, the opening and closing operation of the chuck 4 can be reliably performed.

FIGS. 6 (a) and 6 (b) show an explanatory view of a main part of the sixth embodiment and a longitudinal sectional view, respectively. In the sixth embodiment, the engaging part 16 of the leading tool 2 is connected via a constricted part 28. This is an example in which the locking projection 15 of the extension portion of the chuck ring 3 is opened to the spot facing portion 27 and engaged with the engaging portion 16 through the constricted portion 28 from the spot facing portion 27. Engagement part of joint part 16 and locking part of chuck ring 3
The engagement of the 15 can be performed smoothly and reliably and easily, and it is not easily disengaged, but can be disengaged.

FIG. 7A is a longitudinal sectional view showing the configuration of the seventh embodiment, and FIGS. 7B and 7C are explanatory views showing the engagement and disengagement structure of the tip and the chuck ring in the seventh embodiment. In the seventh embodiment, an opening slit 20 is provided in the chuck ring 3, and the opening passage of the engaging portion 16 of the leading tool 2 is utilized by using the opening slit 20.
This is an example in which the locking projection 15 of the chuck ring 3 is inserted and rotated from 16a to engage with the engagement section 16, and then disengage through the reverse process. There is an advantage that the engagement and disengagement of the portion 16 can be easily performed.

In addition, if a notch 21 dedicated to engagement for engaging the locking projection 15 with the engagement portion 16 is provided at the rear end of the leading tool 2, the engagement of the locking projection 15 with the engagement portion 16 can be achieved. Is the locking projection 15 in the engagement dedicated notch 21
Can be done directly by pressing.

[Effect of the invention]
