JP 2002-254019 ACT 7-34958

In the case of painting using a roller brush, when a roller brush is put in a container in which the paint is stored and pulled up, an appropriate amount of paint may adhere. If you try to paint as it is, the paint will fall before you go to the painting object, and the surroundings will be soiled, or excessive paint will be applied. Therefore, it is necessary to perform a so-called squeezing operation by pressing the roller brush so that it is rubbed against some surface and dropping excess paint.

In the coating tray with a lid of Patent Document 1, for example, a roller brush can be squeezed by a roller squeezing part such as in the lid surface. However, it is difficult to move the container when the lid is set so that the roller ironing unit can be used. Moreover, after use, it is necessary to wash the lid and remove the paint, which is inconvenient.

Since the roller brush container of Patent Document 2 includes an outer container and a disposable inner container accommodated therein, the outer container does not become dirty even when used. After use, the disposable inner container can be removed, and the outer container can be reused by attaching a new inner container. On the other hand, since the inner container can be mass-produced with a small amount of material, the operation cost can be reduced. However, the ironing board that is used while tilted in the container needs to have a considerable thickness in order to ensure strength that does not deform even when the roller brush is pressed against it. In addition, a considerable length is required for mounting along the diagonal line in the container from the upper end to the bottom of the container. Therefore, this ironing board is inevitably expensive compared to the inner container or the like, but is discarded after use, resulting in high operating costs and waste of resources. Furthermore, it is a troublesome task to attach and detach the iron plate every time the inner container is replaced.

An object of the present invention is to provide an inner container for coating that can appropriately apply an amount of coating material to a roller brush and that is inexpensive and easy to use.

In order to solve the above-described problems, the inner coating container of the present invention is a disposable inner coating container used by being mounted in the outer container, which is formed of a synthetic resin, and has a roller at the upper part inside the side surface. Irregularities for ironing are formed. The unevenness for ironing the roller may be formed by a plurality of parallel collars, or may be a plurality of collars inclined so as to descend from the outer side to the center.

According to the inner container for painting of the present invention, it is possible to easily drop the excess paint attached to the roller brush due to the irregularities for roller ironing at the upper part inside the side surface. Since the unevenness for ironing can be provided as a part of the inner container, it can be realized at low cost. It can be easily attached and removed as an inner container and can be disposed of after use.

It is a perspective view which shows the inner container for coating. It is a front view which shows the 1st example of the unevenness | corrugation for roller ironing. It is the same fragmentary sectional view. It is a front view which shows the 2nd example of the unevenness | corrugation for roller ironing. It is a front view which shows the 3rd example of the unevenness | corrugation for roller ironing.

EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated based on drawing. FIG. 1 is a perspective view showing an inner container for painting. The coating container 1 includes an outer container 2 and a disposable inner container 3 for painting that is used in the outer container 2.

The outer container 2 is a generally box-shaped container having an open top, and includes a bottom surface 4 and four substantially perpendicular side surfaces 5a, 5b, 5c, and 5d. Two handles 6 are rotatably attached to the upper portions of the two opposing side surfaces 5a and 5b, and can be grasped as a handle when standing, and retracted to the outside of the container when tilted. It is like that. The bottom surface of the outer container 2 may be horizontal, but a part or all of the bottom may be gently inclined, or a recess for storing a liquid may be formed in part. Further, the four side surfaces 5a, 5b, 5c, and 5d do not have to be completely vertical, but are preferably inclined so as to open outward from the bottom to the top. Since the side surface of the outer container 2 has an outward opening taper, the inner container 3 can be easily attached and detached. The outer container 2 is made of metal or thick synthetic resin so as to have sufficient strength and can be used repeatedly.

The coating inner container 3 is made of a thermoplastic resin such as polypropylene. It is thinner than the outer container 2 and is formed with flexibility. Similar to the outer container 2, the container is a generally box-shaped container having an open top, and has a bottom surface 7 and four substantially vertical side surfaces 8a, 8b, 8c, and 8d. The outer shape of the coating inner container 3 is substantially the same as the inner wall surface of the outer container 2.

Of the four side surfaces 8a, 8b, 8c, 8d of the coating inner container 3, the pair of side surfaces 8a, 8b are in contact with the side surfaces 5a, 5b of the outer container 2 to which the handle 6 is attached. The other two side surfaces 8c and 8d are in contact with the side surfaces 5c and 5d of the outer container 2 to which the handle 6 is not attached. Of the two side surfaces 8c and 8d, an unevenness 9 for roller ironing is provided on the upper portion of at least one surface 8c.

The width of the region where the unevenness 9 is provided is equal to or slightly longer than the length of the roller of the roller brush. In particular, the unevenness 9 is provided in a portion above the paint surface. It is not necessary to provide the unevenness 9 below the side surface 8c.

FIG. 2 is a front view showing a first example of irregularities for roller ironing, and FIG. 3 is a partial cross-sectional view taken along the line AA. FIG. 2 is a view of the side surface 8c as seen from the inside of the container. In this example, the irregularities 9 for roller ironing are formed by a plurality of parallel flanges. In this example, the height and width of the collar are each about 4 mm, but can be appropriately selected within a range of 2 to 6 mm according to the material and hardness of the roller surface, the viscosity of the paint, and the like. About four flanges are provided in parallel, and a valley having a width of about 10 mm is formed between them.

The coating inner container 3 can be produced at low cost and in large quantities by, for example, injection molding or the like, but by providing the mold with irregularities, the irregularities 9 for roller ironing can be simultaneously formed.

Painting is performed by attaching the coating inner container 3 in the outer container 2 and putting a required amount of paint into the coating inner container 3. Since there is a handle 6, it can be easily carried to the painted surface and can be easily moved during the painting operation. The roller brush is put in the inner container 3 for coating, and the paint is adhered to the roller surface. Then, the roller surface can be squeezed by pressing the roller surface against the unevenness 9 for squeezing the roller, and the roller surface can be squeezed. Excess paint removed from the roller surface is collected in the container along the side surface 8c. In this example, the flange parallel to the roller axis effectively squeezes the roller surface.

After use, the coating inner container 3 may be removed from the outer container 2 and discarded. Since the coating inner container 3 can be provided as an inexpensive disposable container, the disposal is simple and the operation cost is low. Even when the type of paint is changed, the inner container 3 for painting may be replaced.

The coating inner containers 3 can be stacked inside each other when not in use. This saves space and is convenient for storage and carrying. The coating inner container 3 can be made thin and flexible, and the height of the unevenness is not so large, so that it is easy to overlap and remove.

FIG. 4 is a front view showing a second example of unevenness for ironing a roller. Similar to the first example, a plurality of parallel flanges are formed. In this example, the collar portion is divided into left and right portions, each of which is inclined so as to gently fall from the outside to the center, and has a reverse C shape. About four ribs of this inverted C shape are formed in parallel.

Excess paint can be removed by pressing the roller surface against the roller corrugation 9. The removed paint flows through the buttock to the center, passes through the blank part between the left and right buttock, and falls into the container.

FIG. 5 is a front view showing a third example of unevenness for ironing a roller. In this example, a large number of protrusions are formed. The protrusion may be cylindrical, spherical, or conical. For example, by arranging the protrusions in a zigzag pattern, the roller surfaces can be made uniform.
