Description

[Detailed description of the invention] This invention contains highly viscous coloring materials, such as watercolor paints, oil paints, paints, lacquers, or inks, and can be sealed for long periods of time when not in use. Immediately before use, the pump connected to the end of the marker is activated to pressurize the coloring material inside the marker body, and the air pressure is used to smoothly flow the coloring material into the pen body, making it easy to mark. It relates to a marker for writing or drawing.

Conventionally, markers that use high-viscosity coloring materials contain the coloring material in an elastic container such as polyethylene.
Markers are marked by squeezing the coloring material out of the opening by squeezing the container and applying pressure, or by filling the container with high-pressure gas and constantly pressurizing the coloring material toward the opening, which easily flows out when marking. Something was coming.

However, due to the solvent permeability of polyethylene, the former cannot be used with anything other than colorants whose main component is water, and the marks must be added by hand, so they cannot be used for precise marks, writing, or drawing. In the latter case, the pressure of the pressurized gas decreases during storage, making it impossible to mark, or requires precise dimensional accuracy to prevent the gas pressure from decreasing, resulting in higher costs. This invention solves these drawbacks and provides a marker whose coloring material always flows out smoothly when marking and whose performance remains unchanged even during long-term storage.

Next, this idea will be explained according to the drawings.

1 is a container body made of plastic, metal, or glass, with a highly viscous coloring material 2 inside;
Contains watercolor enogu, oil enogu, paint, lacquer, or ink.

A stopper 3 is fitted or screwed into the tip of the container body 1, and a valve plate 4 and a valve cylinder 5 are stacked and clamped between the tip of the main body 1 and the inner step of the stopper 3. There is.

The tip of the plug body 3 has a narrow diameter part 31, and the center hole 32 has a sliding cylinder 41 vertically provided from the center of the valve plate 4.
are fitted. The valve cylinder 5 has a flange 51 surrounding it from its tip, and an inner protruding edge 52 surrounding its inner end.

Reference numeral 6 denotes a pen body, which is a rod-shaped body made of plastic, glass, or metal, and a valve body 7 is integrally connected to the bottom of the pen body. The pen body 6 is slidable within the sliding tube 41 and is loosely inserted from the tip so as to be freely retractable.
A spring 8 is stretched between the inner end of the valve body 7 and the tip of the inner protruding edge 52 so that the inner end of the valve hole 42 of the valve plate 4 can be opened and closed. Reference numeral 9 denotes a cylindrical or disk-shaped piston that is slidably and tightly inserted into the container body. 1
0 is a pump cylinder, which is a bellows-shaped cylinder made of an elastic material such as polyethylene or rubber, and has an air hole 101 in the center of its end, and its inner end is fitted or screwed into the end of the main body 1. There is. A valve plate 11 and a valve cylinder 12 are stacked and clamped between the end of the main body 1 and the inner stage of the pump cylinder 10. A valve hole 111 is bored in the center of the valve plate 11, and the valve cylinder 12 has an inner protruding edge 121 at its inner end, a collar 122 at its end, and a valve ball 13 between the valve plate 11 and the inner protruding edge 121. A spring 14 is tensioned to elastically support the valve hole 11 at all times by the valve ball 13.
1 is closed. In the embodiment shown in FIG. 2, a connecting pipe 21 is connected to the end of the main body 1 in place of the pump cylinder 10 of the first embodiment shown in FIG. 23 is clamped, and a spring 24 and a valve ball 25 are built into the valve cylinder 23. A piston cylinder 2 has a center hole 261 bored in the connecting cylinder 21 and a flange 262 around the tip.
6 is slidably and loosely inserted in a watertight manner. Matatsutsu 21
An inner protruding edge 211 is provided around the distal end of the cylinder 26, and the cylinder 26 is resiliently supported by a spring 27 stretched between the distal end of the valve plate 22 and the inner end of the cylinder 26 so that the collar 262 is locked to the inner protruding edge 211 and does not escape. has been done.

Next, the operation of this marker will be explained.

Air hole 101 holding main body 1 in FIG.
When the pump cylinder 10 is pressed in the direction of the arrow with a fingertip, the cylinder 10 is shortened and the air inside the cylinder opens the valve hole 111 against the elastic force of the valve ball 13 and enters the main body 1. When the pressing is stopped, the cylinder 10 returns to its old state due to its elasticity, and the valve ball 13 is also resiliently repelled by the spring 14 to close the valve hole 111 again. When this operation is repeated, the air pressure inside the main body 1 increases and presses the piston 9, and the coloring material 2 is pressurized in the direction of the tip.

On the other hand, in order to mark using this pressurized marker, press the pen body 6 against the mark surface.
The coloring material 2 moves back against the spring 8, and at the same time, the valve body 7 also moves back and the valve hole 42 opens, so that the coloring material 2 passes through the sliding tube 41 and reaches the tip of the pen body 6, where it can be marked.

The operation of the second embodiment is also exactly the same. The marker of this invention applies pressure to the coloring material by operating a pump before use, so even if the coloring material is highly viscous, it can easily reach the tip of the pen body 6 and mark, and pressurizes when not in use. Even if the condition resolves and the pressure returns to normal, it can be immediately pressurized, so there is no need to maintain a high pressure condition, and materials that are impermeable to solvents can be freely selected, so the structure is simple and can be supplied at low cost. It is.
