Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid container such as a water-based ballpoint pen and a correction liquid container, and more particularly to a tip ball type liquid container.

[0002]

[Prior Art]

 As a conventional example, there is an aqueous ball-point pen described in Japanese Utility Model Publication No. 52-10977. In this conventional water-based ballpoint pen, a pipe pen body in which a ball is rotatably held is attached to a neck cylinder, and a ball support rod having an ink passage is slidably fitted into the pen body to form an ink groove connected to the ink passage. The ball support rod is supported from the rear side by an elastic body that is inserted between the pen support and the pen core.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, a ball is rotatably held by the tip of a pipe-shaped pen body, and the ball is pressed and supported by a ball support rod having an ink passage biased forward by an elastic body. Since the water-based ink is used for writing through the play gap between the pen body and the ball, it is difficult to set the play gap to a suitable value and the ink supply amount becomes inadequate, resulting in satisfactory writing. Not only is it difficult to obtain, but there is also the problem that ink leakage and clogging easily occur.

Further, even when the above-mentioned conventional example is used as a correction fluid container, there is a problem that the correction fluid supply amount is inappropriate and not only satisfactory correction cannot be performed but also the correction fluid is easily clogged.

[0005]

[Means for Solving the Problems]

 The present invention is a tip that can appropriately adjust the supply amount of ink, correction fluid, etc., and can not only perform satisfactory writing, correction, application of liquid, etc., but also prevent ink leakage, ink clogging, correction fluid clogging, etc. It is intended to provide a ball type liquid container. That is, in the container of the present invention, the ball 3 is rotatably held at the tip of the tip 2 of the container body 1, and the liquid guiding shaft 5 biased forward by the elastic body 4 is pressed against the ball 3, The protrusion 6 is provided inside the tip tool 2 with a stroke S provided behind the roll 3.

With this configuration, when not in use, the ball 3 is pressed against the tip of the tip 2 by the liquid guide shaft 5 biased forward by the elastic body 4, and the tip of the tip 2 is closed. Therefore, the liquid does not flow out from the tip of the tip tool 2. In use, when the ball 3 is pushed backward together with the liquid guide shaft 5 against the elastic force of the elastic body 4, the ball 3 moves backward with the liquid guide shaft 5 for a maximum stroke S, and the inner tip of the tip 2 is projected. By hitting the portion 6, a gap is created between the tip of the tip tool 2 and the ball 3, and the liquid then flows out along the spherical surface of the rotating ball 3.

By opening and closing the tip of the tip tool 2 in this manner, the liquid supply amount can be appropriately adjusted, and satisfactory writing, correction, liquid application, etc. can be performed. Further, when not in use, the tip of the tip 2 is closed by pressing the ball 3 and there is no liquid leakage. For liquid clogging, the liquid guided by the liquid guide shaft 5 is used to dissolve and eliminate the liquid clogging. Will be.

【Example】

 FIG. 1 is a sectional view showing the construction of one embodiment of the container of the present invention. First, the configuration will be described. In FIG. 1, 1A is a front container main body and 1B is a rear container main body, which constitute a container main body 1 containing a correction fluid 9, for example. Reference numeral 2 denotes a tip tool fixedly attached to the tip portion of the front container body 1A, and a ball 3 is rotatably held at the tip thereof. 7 is a liquid introduction part having a liquid introduction port 7A fixed by sandwiching a flange between the front and rear container bodies 1A and 1B, and 8 is a liquid guide in which a rear large diameter part 8A is loosely inserted in the liquid introduction part 7. The front small-diameter portion 8B is inserted into the tip tool 2.

The liquid guide shaft 5 is fixed in the front small-diameter portion 8 B of the liquid guide portion 8, and the tip of the liquid guide shaft 5 is formed by the spring force of a spring 4 inserted between the liquid guide portion 8 and the liquid introducing portion 7 to form the ball 3 Being pressed by. A protrusion 6 is provided inside the tip 2 with a stroke S formed behind the ball 3. In the embodiment, the liquid guide shaft 5 and the liquid guide portion 8 are both hollow, that is, have a pipe structure, but one or both of them may be solid, that is, have a rod-like structure.

Next, the operation of this embodiment will be described. Put on a cap (not shown) when not in use or while carrying. The correction fluid 9 is introduced from the fluid introduction port 7A of the fluid introduction portion 7, passes through the rear large diameter portion 8A and the outer side of the fluid guide portion 8, passes through the front small diameter portion 8B, the outer side, and the fluid guide shaft 5 and the outer side. Is guided to the rear of the ball 3. The ball 3 is pressed against the tip of the tip 2 by the liquid guide portion 8 and the liquid guide shaft 5 that are biased forward by the spring force of the spring 4, and the tip of the tip 2 is closed. The correction fluid 9 does not flow out from the part.

In use, when the ball 3 is pressed against the corrected portion and moved backward together with the liquid guiding shaft 5 and the liquid guiding portion 8 against the spring force of the panel 4, the ball 3 is at maximum, and the stroke S is the only liquid guiding. It moves backward until it hits the protrusion 6 inside the tip 2 together with the shaft 5 and the liquid guide portion 8, and a gap is created between the tip of the tip 2 and the ball 3 so that the correction fluid 9 rotates on the spherical surface of the ball 3. It can be spilled along and used for correction.

By opening and closing the tip of the tip tool 2 in this manner, the supply amount of the correction fluid 9 can be appropriately adjusted, and satisfactory correction can be performed. Further, when not in use, the tip of the tip 2 is closed by pressing the ball 3, and there is no liquid leakage. For liquid clogging, the correction liquid 9 guided by the liquid guiding shaft 5 dissolves it. This will clear the liquid clogging.

In the present invention, the outer peripheral edge of the tip of the liquid guide shaft 5 pressed by the ball 3 may be rounded and rounded as shown in FIG. 1 to smooth the liquid flow. As shown in FIG. 2 (A), a slit 5A may be provided at a symmetrical portion of the tip end portion of the liquid guide shaft 5, or as shown in FIG. 2 (B), wavy concavities and convexities 5B and 5C may be formed. Alternatively, as shown in FIG. 3, the tip 2 may be formed of a pipe, and the projection 6 may be provided by squeezing it. It is obvious that the container of the present invention is not limited to the correction fluid container, and can be applied to an aqueous ballpoint pen or the like.

[0014]

[Effect of the device]

 As described above, according to the present invention, the ball 3 is rotatably held by the tip of the tip 2 of the container body 1, and the liquid guide shaft 5 biased forward by the elastic body 4 is attached to the ball 3. Since the protrusion 6 is provided on the inside of the tip tool 2 by pressing it and making a stroke S behind the ball 3, the tip of the tip tool 2 can be opened and closed by the forward and backward movement of the ball 3, so that ink, correction fluid, etc. Not only can the amount of liquid supply be adjusted appropriately and satisfactory writing, correction, and liquid application can be performed, but liquid leakage and liquid clogging due to drying can be prevented.
