When the paint operation is conducted with a conventional paint roller, a painting part of a paint roller is coated with paint, the paint roller is rolled on the surface of a paint target, and the coating and rolling are continuously repeated. The repeated operation is time-consuming, lowers operation efficiency, and can be risky when the paint operation is conducted at heights. In order to reduce unnecessary operation, the paint roller of the present invention includes a paint storage container and a paint discharging amount adjusting unit, wherein the paint storage container stores paint in the paint roller and discharges the paint gradually to the outside of the paint roller. The paint roller does not require a worker to repeatedly coat the paint thereon until the entire amount of paint in the paint container is used, thereby enabling the paint operation to be conducted continuously and reduces the time and labor required for the paint operation significantly. The present invention can also reduce the unnecessary operation to reduce risks present in the operation. The roller can uniformly adjust the discharging amount of the paint in order to ensure high quality and uniform paint operation.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint roller,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a paint roller for use in painting by a method of rolling a cylindrical roller having paint on a surface of a target to be painted.

Methods of painting include using a brush, using a spray gun to spray pressurized air with paint, and using a paint roller.

When painting using a spray gun, a separate device capable of pressurizing the air is required, and a part of the sprayed paint is dispersed in the air during coating, so measures against the environmental pollution are required.

On the other hand, when using a brush or a paint roller, a separate device or a special countermeasure is relatively unnecessary, which is generally used in a case of painting.

The method of painting using a roller is advantageous in that a relatively large area can be easily coated by adjusting the size of the roller.

Conventional paint rollers are generally of the type having a paint adsorbent portion which can be painted around a rotatable cylindrical shape.

In order to paint with such conventional paint rollers, the paint is applied to the paint adsorption portion of the roller, the roller is rolled on the surface of the object to be painted, the paint is again applied to the paint adsorption portion of the roller Repeat form of repetition must be repeated.

The reason for coating with the roller is to facilitate coating on a relatively large area, so that it is common to connect a long knob to the roller so that the roller can easily reach high or far parts.

Thus, in order to paint with the paint roller, it is necessary to repeatedly carry out the troublesome operation repeatedly to apply the paint to the paint roller with the long handle.

Even if you use a paint roller that does not have long handles, this repetitive behavior is an essential behavior that can not be eliminated by using a paint roller, which leads to many inefficiencies and hazards.

In order to uniformly and evenly apply the paint to the conventional paint roller, it is necessary to appropriately perform the operation of rolling or squeezing the paint roller in the paint container containing the paint. This operation is not only time-consuming but also requires high- It is also.

If too much paint is applied to the paint roller, the paint may fall down before the paint is painted on the paint surface. If too little paint is applied to the paint roller, the paint is not properly applied. If it is not uniformly buried, the coating is not uniformly performed. Therefore, it takes a lot of effort and time to put the paint on the rollers.

In addition, if the paint is hanging on a line to paint a high area or painted on a ladder, it can be very dangerous and repetitive to paint the paint roller.

In order to paint with a conventional paint roller, the paint roller must be rolled on the surface to be coated. At this time, the paint on the paint roller is rotated by the centrifugal force generated when the paint roller rotates.

Such protruding paint may fall on the face of the person who paints, which may interfere with the work, or may fall around the work area and cause damage to the surroundings.

In order to solve the above-mentioned problems of conventional paint rollers, the paint roller of the present invention is characterized in that a paint container capable of containing paint is built in the paint roller.

By allowing the paint container to be embedded inside the paint roller, it is not necessary to repeat the process of applying paint to the paint roller like a conventional paint roller until the paint in the built-in paint container is exhausted.

And, when the paint in the built-in paint container is exhausted, the paint can be continued by simply opening the lid of the paint container and replenishing the paint.

Further, the paint roller of the present invention is characterized in that means for adjusting the amount of paint flowing out from the paint container in which the paint roller is installed is provided.

Thus, by controlling the amount of paint flowing out of the paint container depending on the concentration of the paint or the speed of the painting operation, it is possible to continuously perform a uniform and stable painting operation.

In addition, the paint roller of the present invention is characterized in that a roller cover is provided to prevent the paint from protruding from the roller which is rotated during the painting operation.

The roller cover not only significantly reduces the occurrence of contamination around the paint due to the splashing of the paint during the painting operation, but also plays a role in securing the safety of the operator by preventing splashing on the body including the operator's face.

The paint roller of the present invention makes it possible to perform continuous painting without repetitive work of putting the paint on the roller, so that it saves time and effort that eliminates repetitive work of applying paint to the roller.

In addition, continuous painting is possible until the paint in the paint container built in the roller is completely consumed, thereby enhancing the efficiency of the work and enhancing the quality of the painting by increasing the concentration of the work Can be expected.

In addition, the paint roller of the present invention can appropriately control the amount of paint flowing out from the built-in paint container, so that the quality of the paint can be kept constant.

In addition, when it is necessary to suspend the work during the painting operation, the paint can be prevented from flowing out by completely blocking the paint from flowing out of the paint container built into the paint roller.

The paint roller of the present invention is provided with a cover that can prevent the paint from splashing out from the paint roller during the operation so that the contamination of the surroundings can be prevented and the operator can safely perform the painting work.

In addition, the paint roller of the present invention has a structure capable of disassembling and assembling, and can be reused by cleaning the paint roller with an appropriate solvent after painting operation.
