【Example】

 FIG. 1 is a partially cutaway plan view of the construction of the first embodiment of the container of the present invention. In FIG. 1, reference numeral 2 denotes a lead replenishing port provided at the center of the front end of the outer cylinder 1, which projects from the outer cylinder 1. 2A is the protruding portion. A chuck 3 which is pressed against the core supply port 2 by a knock to open and which is closed by its own elastic force when the knock is released is inserted in the outer cylinder 1 with its knock portion 3A protruding. A large number of cores 4 are housed in the chuck 3. 3B is the bottom of the chuck 3.

The chuck 3 is locked to the outer cylinder 1 by a locking means 5 that prevents the chuck 3 from being detached rearward. The locking means 5 is provided with, for example, counterbore holes 6 each having a rear end open and engaging holes 8 communicating with these through a neck 7, and the rear surface of the chuck 3 respectively has the counterbore holes. 6, a locking portion 9 that engages with the engagement hole 8 via the neck portion 7 is provided. Further, the locking portion 9 is pushed into the engaging hole 8 by a knock to expand the engaging hole 8 and the elastic force of the knock is released to restore the original state.

At least the contact surface of the chuck 3 of the contact surfaces of the lead replenishing port 2 and the chuck 3 is a tapered surface 10, and the inner surface of the chuck 3 on the opposite side of the tapered surface 10 is a downward slope toward the center. It is 16. The downward slope 16 allows the core 4 in the chuck 3 to be gathered in the central portion and smoothly dropped from the core supply port 2 when the chuck 3 is opened.

When the core 4 is placed on the bottom 3 B of the chuck 3 and the core 4 is inserted from the rear end of the outer cylinder 1 in the first embodiment having the above-described configuration, the locking portion 9 of the chuck 3 moves from the counterbore hole 6 to the neck portion. 7 is pushed out and spread, and when it is beyond this, it is locked in the engaging hole 8.

When replenishing the lead into a lead tank such as a mechanical pencil, when the lead replenishing port 2 is directed downward and the knock portion 3A is knocked, the engaging portion is pressed by the engaging hole 8 and the engaging hole is pushed. At the same time when the lead 8 is expanded, the chuck 3 is pressed and opened by the lead replenishing port 2, and the lead 4 can be dropped from the projecting portion 2A of the lead replenishing port 2 into the lead tank to be replenished. When the knock is released after the supply of the lead 4 is completed, the engaging hole 8 returns to its original position by its own elastic force, and at the same time the chuck 3 returns to its original position by its own elastic force and closes. When the wick 4 is held, the wick 4 can be dropped back into the chuck 3 by opening the chuck 3 by opening the wick supply port 2 and knocking the knock portion 3A.

FIG. 2 is a plan view showing a partially broken structure of the second embodiment. The second embodiment is an example in which the contact surfaces of the lead replenishing port 2 and the chuck 3 are tapered surfaces 10 and a protective cover 17 for protecting the projecting portion 2A of the lead replenishing port 2 is provided on the tip end side of the outer cylinder 1. .. A protrusion 21 is provided outside the chuck 3 or inside the outer cylinder 1, for example, outside the chuck 3. In this way, the contact surface of the lead replenishing port 2 is also made into the tapered surface 10 and / or the protrusion 21 is provided, so that the chuck 3 can be opened and closed more smoothly. Further, since the protrusion 2A is protected by the protective cover 17, there is no possibility that the protrusion 2A will be damaged during transportation.

FIG. 3 is a cross-sectional plan view showing the configuration of the rear portion of the third embodiment, FIG. 4 is a vertical sectional side view of the rear portion of the outer cylinder in the third embodiment, and FIG. 5 is a right side view thereof. In the third embodiment, an elastic body holding through hole 12 is provided in the rear portion of the chuck 3 in the longitudinal direction and the direction perpendicular to the chuck 3 in the first and second embodiments, and the rear surface 14 of the through hole 12 and the outer cylinder 1 are provided. A chuck return spring 11 is inserted between the elastic member guide / insertion groove 13 (see FIGS. 4 and 5) formed on the upper and lower inner surfaces of the rear portion and the engaging portion 15, which is the end surface.

In the third embodiment having the above-described structure, when replenishing the lead into the lead tank such as a mechanical pencil, the lead replenishing port 2 is directed downward and the knock portion 3A is pushed against the chuck return spring 11 to knock. When knocked for A minutes, the chuck 3 is pressed and opened by the lead supply port 2, and the lead 4 can be dropped from the projecting portion 2A of the lead supply port 2 into the lead tank for supply. After the replenishment of the lead 4, when the knock is released, the chuck 3 returns to its original position and closes due to its own elastic force and the spring force of the chuck return spring 11, and at this time, the chuck 4 holds the lead 4 between them. In this case, the lead 4 can be dropped back in the chuck 3 by opening the chuck 3 by knocking the knock portion 3A with the lead supply port 2 facing upward.

In this case, not only the elastic force of the chuck 3 itself but also the spring force of the chuck return spring 11 causes the chuck 3 to return to its original position and close, so that the chuck 3 can be opened and closed more reliably and smoothly. Can be done.

FIG. 6 is a cross-sectional plan view showing the rear structure of the fourth embodiment, and FIG. 7 is a cross-sectional plan view showing the rear structure of the fifth embodiment. The fourth and fifth embodiments are examples in which the chuck restoring elastic body 11 is integrally provided on the rear surface 14 of the elastic body holding through hole 12 provided in the rear portion of the chuck 3, and the end portion of the elastic body 11 is Is locked at the front end of the axial hole 8A communicating with the engaging hole 8, and its action is exactly the same as in the third embodiment. The shape and structure of the elastic body 11 are not limited to those shown in the figure.

In the present invention, the outer diameter of the projecting portion 2A of the lead replenishing port 2 is set to a thickness that can be inserted into a lead tank such as a mechanical pencil so that the lead refilling into the lead tank can be performed more reliably and easily. You can Further, it is preferable that the outer cylinder 1 is made of a transparent resin because the state of the cores 4 in the chuck 3 and the number of remaining cores 4 can be known. As in the third to fifth embodiments, the chuck restoring elastic body 11 may be separate from or integral with the chuck 3, and the point is that it should be inserted between the outer cylinder 1 and the chuck 3. ..

[0018]

[Effect of the device]

 As described above, according to the present invention, the core replenishing port 2 is provided at the tip of the outer cylinder 1, and the core replenishing port 2 is pushed by a knock and opened to release the knock. Since the chuck 3 having the above is inserted into the outer cylinder 1 and the core 4 is accommodated in the chuck 3, the outer cylinder 1 and the chuck 3 can be constituted by two parts, and the structure is simpler than the conventional one. Not only can the cost be reduced, but the wick can be easily replenished.
