Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tip ball type liquid container such as a water-based ballpoint pen, a correction liquid container and a perfume container.

[0002]

2. Description of the Related Art Conventionally, a container of this type has been used as a conventional container.
A tip ball type liquid container as described in Japanese Patent No. 93876 has been proposed. In this conventional example, the container body 2
The ball 23 is rotatably held by the tip of the holder 22 of No. 1, and the liquid guide shaft 25 biased forward by the spring 24 is pressed against the ball 23, and a stroke S is opened behind the ball 23 to make the holder 22. The protrusion 26 was provided inside the.

[0003]

However, in the above-mentioned conventional example, since the projection 26 for restricting the rear position of the ball 23 is provided, not only the structure is complicated and the cost becomes high, but also the projection is formed. However, there is an inconvenience that the flow of the ink, the correction liquid, etc. is impaired by the obstacle 26, and the liquid cannot be properly supplied.

Therefore, the present invention eliminates the above-mentioned conventional inconveniences and can appropriately adjust the supply amount of ink, correction liquid, and the like, and can not only perform satisfactory writing / correction / liquid application but also ink leakage, An object is to provide a tip-ball type liquid container having a simple structure capable of preventing ink clogging, correction liquid clogging, and the like. In particular, in the conventional example, the projection for regulating the rearward position of the ball is not required, and the structure is simplified, and since the ball does not completely retract to the tip of the tip, the tip or the like is not damaged and the operating member, etc. The purpose is to prevent rattling.

[0005]

In order to achieve the above object, according to the present invention, a ball is rotatably provided at the tip of a tip tool provided at the tip of the container body, and the ball is made of an elastic material. In a tip ball type liquid container which is pressed by an actuating means biased forward by the holder, a holder is provided at the tip of a tip tool located in front of the container body filled with the liquid and the liquid introduction wall having the liquid introduction port. Is fixed, and the ball is held by the tip of the holder, the rear portion of the ball is brought into contact with the actuating means, and the elastic body is interposed between the actuating means and the liquid introducing wall. ,
Further, a tip ball type liquid container in which the rear position of the operating means is regulated by the liquid introducing wall can be obtained.

[0006]

When using this liquid container, first shake the container well to stir the liquid inside, remove the cap and fit it on the rear end of the container body, and then place the ball protruding from the tip of the tip on the paper surface. When the ball is pressed while hitting the ball, the actuating member such as the ball is retracted against the spring. When the ball is separated from the paper surface, etc., the action member returns to its original position by the action of the spring, but at this time, the liquid in the container body is sent forward by the action of the pump, and the holder such as the tip at the tip and the ball It bleeds from between and becomes usable. After use,
It suffices to remove the cap from the rear end and cover it with the front end tool.

[0007]

1 is a longitudinal sectional view showing the construction of a pen type correction fluid container according to an embodiment of the present invention. In the figure, a tip 2 is screwed to the front of the container body 1. That is, a female screw 1a is formed on the inner periphery of the front part of the container body 1, whereas a male screw 2a is formed on the outer periphery of the rear part of the tip tool 2.
Are formed and both are detachably screwed. The container body 1 and the tip 2 are separated by a liquid introduction wall 3, and a liquid introduction port 3 a is formed on the side wall of the liquid introduction wall 3.

A tip 5 as a holder for rotatably supporting a ball 4 is press-fitted and fixed to the tip of the tip 2. An operating member 6 whose tip contacts the rear portion of the ball 4 is axially movably inserted into the tip 5. A spring 7 for urging the operating member 6 forward is inserted between the operating member 6 and the front surface of the liquid introducing wall 3. The rear end of the operating member 6 is fixed in the receiving member 8. This receiving member 8
Since the rear portion is inserted in the recess 3b of the liquid introducing wall 3 so as to be movable in the axial direction, it can be moved without rattling.

Note that, as shown in FIG. 2, the length of the gap between the receiving member 8 and the liquid introducing wall 3 which constitutes the operating means is defined by the diameter L1 of the exposed portion of the ball 4 protruding from the tip 5. If L2 is shortened, when the ball 4 is pressed against the paper surface, etc.
Will not be worn or damaged by hitting the paper surface.

Further, the tip 2 is covered with a cap 9 having an airtight function to which a clip 9a is attached. An airtight seal portion 9b is hung from the top of the cap 9 on the inner circumference of the cap 9. Reference numeral 10 in the figure is an agitator for agitating and homogenizing the liquid in the container body 1 when the container is shaken.

Next, the operation of the liquid container according to this embodiment will be described. First, with the correction liquid contained in the container body 1 prior to use, the container is shaken to move the stirrer 10 to stir the correction liquid. Then, the cap 9 is removed, and the cap 9 is fitted and attached to the small diameter portion 1b formed at the rear end of the container body 1. Then, the container is erected and the ball 4 at the tip is pressed against the paper surface or the like. Then, the actuating member 6 and the receiving member 8 are retracted against the forward biasing force of the spring 7, but the rear portion of the receiving member 8 abuts against and is regulated by the liquid introducing wall 3, so that the balls 4 are unnecessarily large. Will never retreat. Then, when the tip is separated from the paper surface or the like, the operating member 6 and the like return to the original position again. In this process, the liquid in the container body 1 is sent forward through the liquid introduction port 3a of the liquid introduction wall 3 by the pump action.

More specifically, the ball 4 is normally exposed from the tip of the tip 5 by about one third, and the liquid such as the correction liquid stored in the container body 1 is at the tip of the ball 4.
Is retracted when pressed against the paper surface or the like, but the rear position is regulated by the rear end of the receiving member 8 provided with the actuating member 6 coming into contact with the liquid introduction wall 3, so that it is more than necessary, that is, from the tip 5. There is no possibility that the part of the projected ball 4 retreats into the chip 5 and pushes the liquid introduction path more than necessary. Therefore, since the ball 4 does not completely retract into the chip 5 but protrudes somewhat, even if a relatively inexpensive brass chip 5 or the like is used, these directly contact the paper surface or the like and are worn or damaged. Never.

Next, when the pressing of the ball 4 at the front end against the paper surface or the like is stopped, the actuating member 6 which has been moved backward starting with the ball 4 returns to the original position. At this time, the liquid in the container body 1 is sent to the inside of the tip tool 2 through the liquid introduction port 3 a provided on the side wall of the liquid introduction wall 3, and is transmitted between the tip 5 and the operating member 6 to reach the ball 4. It can be used by reaching it.

FIGS. 3 and 4 show another embodiment of the present invention. In this case, a stainless pipe 11 formed by extrusion molding is used instead of the tip 5 in the above embodiment. According to this embodiment, if the ball is movable in the pipe 11 and the both ends are crimped in advance, the front-back directionality does not have to be a problem when assembling as in the case of the chip 5, so that the assembly is easy and a large amount can be obtained. It has the advantage of being suitable for production.

FIGS. 5 and 6 show modified examples of the actuating member 6 and the receiving member 8 of the present invention. In the above-mentioned embodiments, these members are rod-shaped stripped members.
In this modified example, both are formed to be hollow with through holes 6a and 8a. Even in this case,
The liquid introduction port 3a of the liquid introduction wall 3 may be formed on the side wall as in the above embodiment. According to this modification, since the through holes 6a and 8a are formed inside these members as well, the area of the container main body 1 through which the liquid passes increases, so that there is an effect that the liquid flows better.

[0016]

As described above, according to the present invention, the supply amount of the liquid such as ink and correction liquid can be appropriately adjusted, and satisfactory writing, correction and liquid application can be performed. There is an effect that a durable tip-ball type liquid container having a simple structure and capable of preventing ink leakage, ink clogging, correction liquid clogging, etc. and having good operability can be obtained.
