Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to inks containing pigments with large or heavy particles, high viscosity inks, or quick-drying components, and liquids such as lubricating oils, adhesives, and cosmetics (hereinafter referred to as specific liquids). The object of the present invention is to provide a new ink or other liquid supply device that is effective when installed in writing instruments and applicators that use the following.

Conventionally, in this type of ink or other liquid supply device, for example, positive pressure is always applied to the ink or other liquid by the vaporization pressure of a sealed gas or volatile solvent, or the pen tip is immersed by pressing it against another object and the valve is closed. There are several types of writing instruments that open the ink container and supply ink and other liquids to the pen tip using the internal pressure of the ink container. It is unsuitable because the relationship between the amount of liquid flowing out and positive pressure is unbalanced, and the latter is also unsuitable for brush tips and brush tips where it is difficult to crush the tip because it needs to be pressed against another object. There are some inconveniences.

The present invention relates to an ink or other liquid supply device that eliminates the above-mentioned disadvantages and is suitable for specific liquids, such as a blower, pump, etc., which increases the internal pressure by introducing outside air into a sealed container for ink or other liquid. The gist of the present invention is to include a blower and a structure for supplying a 1° knock liquid to areas such as the tip of the brush, the nib of the pen, and the tip of the brush to which a positive pressure is applied using the internal pressure described above.

In the illustrated embodiment, a partition cup (5) that is movable up and down separates the inside of a cartridge container (3), which has an ink discharge port (2) on the bottom surface that is opened by piercing with a pipe-shaped needle (1), which will be described later. The partition cup (5)
A plastic self-blade return mechanism that stores ink (6) on the lower side and sucks and exhausts outside air through an intake hole (9) and an exhaust hole aυ by expanding and contracting a bellows body (8) on the upper end surface of the cartridge container (3). Equipped with a type bellows (111) and an air intake hole (
9) On the top surface, there is a valve body made of a leaf spring that closes the intake hole (9) when it collapses into a straight line and opens when it returns to an arc shape, and the exhaust hole QQ has a coil spring 0 and a ball 1'. In addition, the cartridge container (3) is equipped with a safety valve αη consisting of a leak hole (141, a bamboo spring spring 9 and a movable closing plate (1G+) on the top surface of the cartridge container (3), and the cartridge container (3) is attached to the shaft cylinder. Insert the ink discharge port (2) into the tip of the coaxial cylinder (18) with the pipe-like needle (1) provided through the cap member (II) by pushing it into the a-shaped tube from the tail end, and insert the ink into the cap member (I9). Attach the occluding body (A), the ink jetting body made of open-cell porous material υ, and the brush tip (C), and also removably screw the tail end camp (C) to the tail end opening of the shaft tube (181). Then, on this tail end cap (c), attach the above bellows (
A knock button (C) with a return spring Qa for crushing No. 111 is attached, and an outside air intake hole (C) is also opened in the peripheral wall of the shaft cylinder brocade corresponding to the bell ring.

That is, in the above case, when the knock button (c) is pressed, the valve body a6
is crushed and blocks the intake hole (9), and as the bellows collapse, the air inside the ball (L31) is slightly lowered and the upper side of the partition cup (5) in the cartridge container (3) is released. As soon as the ball moves into the air chamber (goods) and the press is completed, the ball is released 3.
′ returns to close the exhaust hole (lυ), and when the above pressing is released, the valve body σ2 uses its restoring force to lift the knock button (c), open the intake hole (9), and open the blowing ring. It also expands by sucking air from the outside air intake hole through the intake hole (9), that is, pressing the knock button (C) and pressing the button (C) and releasing the button. By doing this alternately, the air pressure inside the air chamber is increased (in this case, when the air pressure reaches a predetermined value or more, the safety valve ση is activated), and in this way, the above air pressure imparts a pressing blade to the partition cup (5). The ink (6) on the lower side of the partition cup (5) is supplied under positive pressure to the ink storage body (A), the ink jet body c2υ, and the brush tip (C) through the pipe-like needle (1). be.

As described above, the present invention includes a blower such as a blower, a pump, etc., which increases the internal pressure by introducing outside air into a sealed container for a liquid such as ink, and a blower such as a blower or a pump that increases the internal pressure by supplying external air into a sealed container for a liquid such as ink, and a brush tip, a pen tip, etc. It is characterized by having a configuration for supplying the tip of the brush to areas such as the tip of the brush, so that by appropriately performing the knocking operation and canceling the knocking operation, the area such as the tip of the brush, the nib of the brush, and the tip of the brush can be moistened with liquid such as ink suitable for use. It is possible to state
In addition, as mentioned above, when supplying liquid such as ink, the tip of the brush,
There is no need to press the pen tip, brush tip, etc. against other objects, and there is no risk of damaging the same area, and it only has an excellent effect that can completely achieve the intended purpose. Since positive pressure is applied to the liquid such as ink, it has practical effects such as continuous writing even when the writing light is directed upward.

The present invention can also be carried out by using a blower such as a blower pump instead of the bellows, or the bellows may be attached externally, and a whistle may be incorporated into the bellows to make it suitable for children. It is also possible to do so.
