Description

[Detailed explanation of the idea] Industrial applications This invention concerns a brush for applying paint.

Conventional technology After using a conventional brush for painting, if you do not completely remove the paint by washing it with a solvent etc. after applying as much of the adhered paint as possible, the remaining paint will harden on the bristles. As a result, the brush cannot be reused.

Problems that the invention aims to solve However, this is a waste of labor, solvent, and paint, so we try to avoid doing it as much as possible.

Measures to solve the problem For this reason, after using the brush, remove the hair 1 with the paint still remaining on the hair transplant base 2, that is, the root of the hair where the hair is planted. , and a cover 3 fitted therewith, so that it can be sealed in a small internal space 8 which is completely surrounded by and hermetically sealed off from the outside.

Operation Since the above-mentioned closed space 8 is small, saturation is reached after only a small amount of the solvent evaporates from the remaining paint, and evaporation does not proceed any further. Therefore, the hair portion does not become solidified.

The same goes for paints that harden when oxidized by oxygen in the air, as the oxygen quickly runs out and cannot be replenished.

This is for the same reason that various types of paints do not harden easily in sealed cans, even if a small amount of paint remains and there is a considerable amount of air in the can. However, it is difficult to maintain absolute airtightness over a long period of time, so it is normal for the material to harden.

Example To explain this in detail with respect to a drawing showing an example of the present invention, which is in a standby state for reuse after being used for painting, when non-use is expected for a long period of time, the conventional method described above is used. Remove the paint completely from the hair, but if not, proceed as follows.

The bristles 1 are removed by applying excess paint to the coated surface until the paint does not drip, and the cover 3 is fitted to the bristle base 2 of the brush at the fitting part 4. At this time, if there is a risk that the paint may adhere to the fitting part 4 of the cover 3, use a thin film such as polyethylene to
Attach it to the side of the

In addition, it is expected that the period of non-use will be a little longer,
Depending on the type of paint, etc., if necessary, a sealing tape may be pasted on the outside of the fitting portion 3, or a sponge 5 may be attached to the inside of the sealed space 8, and a small amount of solvent may be soaked into the sponge. Afterwards, measures are taken to reduce evaporation of the solvent in the paint remaining on the bristles 1, such as by fitting the cover 3.

Particularly when the painting work has been stopped for a long time, the period of prevention of caking can be extended by replenishing the sponge 5 with the solvent soaked in it. In practice, it is quite difficult to have
It greatly contributes to the effectiveness of achieving the objective.

After these measures are completed, hang the handle 6 through a hole or string, and place it in a place with little combustible material, away from fire, and with little temperature change. Note that the sponge 5 is held down by a fastener 7 to prevent it from moving within the internal space 8.

In this state, the hair 1 is sealed inside the internal space 8,
The paint will not harden for at least a while and can be reused at any time. In case of prolonged non-use, the above-mentioned conventional treatment should be carried out before hardening. In addition, the flock base 2 and cover 3 are not permeable to gases or liquids, and are not eroded, deformed, or impregnated by paints, solvents, etc., and are usually made of metal or hard plastic. .

Effects With this invention, the length of time that the paint adhered to the bristles does not solidify varies depending on the type of paint, the size of the brush, the temperature, and other factors, but the sponge 5 can be refilled with solvent. However, depending on the situation, it usually lasts at least a week, and if you replenish the lost solvent, it is possible to prevent caking for more than a month, so it is definitely convenient. be. In addition, cover 3 has damaged hair 1, insect bites,
It also serves as a protective device to prevent dirt, etc.
