Description

[Detailed Description of the Invention] The present invention relates to a paint cup for a spray gun that is attached to a spray gun and used to contain paint to be applied by the spray gun, and particularly relates to a paint cup that sucks up paint through a suction pipe. It is.

Conventionally, this type of paint cup consists of a paint cup main body 1 having an opening at the upper end as shown in FIG. These extend into the cup body 1 through the cap 2 in an airtight manner, and are supported downward by a suction pipe 4 fixed to the spray gun 3.

The paint contained in the cup body 1 is sucked up through the suction pipe 4 by the ejector action of the air passing through the spray gun 3, and is sprayed together with the air.

Therefore, in such a conventional paint cup, in order to compensate for the decrease in pressure in the space partitioned by the cup body 1 and the cap 2 due to the suction of paint, the cap is removed as shown in FIG. However, the spray gun 3 is not always used for spray painting in a horizontal, stationary state, but is tilted or swung in various directions. As a result, the paint cup is also tilted and moved, and as a result, the paint in the cup body 1 easily reaches the cap 2 and leaks to the outside through the vent hole 5.

The paint cup for a spray gun of the present invention is designed to eliminate the above-mentioned drawbacks, and includes a paint cup body having an opening at the upper end, a cap that is airtightly attached to and detachable from the opening of the cup body, and this cap. a vent hole formed in the cup body; an inverted U-shaped gutter-like yoke for pressing and fixing the cap to the cup body so as to close the opening of the cup body; It is characterized by a bent tube opening in the gutter-like part of the yoke.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 2 and 3, 1 is the cup body, 2 is a cap attached to the outer periphery of the opening of the cup body 1, 4 is a suction pipe fixed to the cap 2, 5 is a ventilation hole, and 6 is the cap. 2 is an inverted U-shaped yoke with a gutter-like cross section; 7 is a pin protruding from the side surface of the cup body 1 to engage with the lower engagement recess of the yoke 6; A lever disposed between the cap 2 and the yoke 6 and screwed onto the outer periphery of the suction pipe 4 in order to press against the cup body 1 is shown;
When the yoke 6 is raised relative to the suction pipe 4 by rotating the yoke 6, the cup body 1 is eventually fixed to the suction pipe 4 because the yoke 6 and the cup body 1 are connected to each other via the pin 7. The cap 2 is now firmly pressed against the cup body 1.

Accordingly, in the present invention, a bent tube 9 having, for example, a U-shape is provided on the outside of the cap 2, one end of which is removably connected to the ventilation hole 5, and the other end of which is opened to the gutter-shaped portion of the yoke 6. .

Since the spray gun paint cup of the present invention has the above-described structure, the decrease in pressure due to the decrease in paint due to the suction pipe 4 is compensated for by the air introduced through the tube 9 and the vent hole 5 of the cap 2.

Therefore, due to the tilting, rocking, etc. of the paint cup, the ventilation hole 5
When paint leaks out of the cap 2, the paint first reaches the inside of the tube 9, and then is guided by the gutter-like part of the gutter-like yoke 6 and flows downward toward the cup body 1. Therefore, the paint will not drip into undesirable areas and cause stains, and will not drip to the outside until the inside of the tube 9 is filled with the leaked paint.

If the lower end of the gutter-like portion of the yoke 6 is made flat and in contact with the side surface of the cup body 1, the leaked paint will not drip directly from the lower end of the yoke 6, but instead will flow into the cup body 1.
This is even more preferable because it runs down the sides of the container and reaches its bottom, where it drips down.

Furthermore, if the tube 9 is made transparent, it is possible to easily observe from the outside that the leaked paint has reached the tube 9, thereby preventing the leaked paint from dripping to the outside.

Furthermore, as shown in Fig. 4, it is composed of a flange IOA sandwiched between the cup body 1 and the cap 2, and an inclined membrane body 10B, and has ventilation in the lower position when attached to the suction tube. If the liquid leakage prevention film 10 with the small ventilation holes 11 is further provided, the paint leaked from the small ventilation holes 11 to the cap 2 side can easily return into the cup body 1 before reaching the ventilation holes 5.

As described above, according to the present invention, the tube 9 and the trough-like yoke 6
The extremely simple structure of only providing a spray gun has great benefits such as preventing the internal paint from leaking out to the outside even when the spray gun moves, and allowing painting work to be carried out completely freely.
