When the user uses paints of multiple colors for painting, arrange the inner containers 510 for the number of colors, put the paints in them, and put the container 510 containing the paints of the color to be used in the paint bucket 500. By arranging it, the painting work could be performed. Therefore, it is not necessary to prepare a plurality of paint buckets 500. However, the net 520 adjusts the paint attached to the coating roller, and since the paint currently in use is attached to the net 520, the net is placed in the container 510 containing the paint of another color as it is. I couldn't soak 520. For this reason, it was necessary to wash the net 520 each time a different color was used, or to prepare as many nets as there were colors.

The container according to the present invention is a container in which a liquid can be contained, and the container has an upper portion having an opening and an edge around the opening, and a bottom portion located at the bottom of the container. A container having a side portion and having at least one protrusion on the side portion, and the area of the opening portion is larger than the area of the bottom portion.

In one embodiment of the invention, the liquid is a paint, the at least one protrusion is used to adjust the amount of paint attached to what the paint is applied to, and the at least one protrusion is endless or The cross section of the at least one protrusion on a surface having a plurality of ends and perpendicular to the direction in which the at least one protrusion extends may be curved.

In one embodiment of the invention, the at least one protrusion may be a series of lines bent up or down.

In one embodiment of the invention, the at least one protrusion may be linear and substantially parallel to the bottom.

In one embodiment of the invention, the at least one protrusion has a first protrusion and a second protrusion, the first protrusion and the second protrusion having the side surface and the bottom. When projected onto the sides created by, those projections may at least partially overlap.

In one embodiment of the invention, the at least one protrusion has a first protrusion and a second protrusion, and the first protrusion and the second protrusion have a side surface having them. When projected onto the sides extending from the opening to the bottom, those projections may at least partially overlap.

In one embodiment of the invention, the at least one protrusion may be in the form of a plurality of bent lines.

In certain embodiments of the present invention, the material of the container may be a transparent or translucent resin.

In one embodiment of the invention, the container may be made by pressing the resin once with a die.

In one embodiment of the present invention, the length of one side of the inside of the opening may be 200 mm to 250 mm, and the length of the other side may be 150 mm to 190 mm.

Since the container according to the present invention has at least one protrusion on the side portion, the amount of paint attached to a paint, for example, a coating roller, a brush, a brush, or the like can be adjusted. This eliminates the need for a net for adjusting the paint. Further, since the area of the opening is larger than the area of the bottom, the containers according to the present invention can be stacked, and the space for transporting and storing the containers can be made smaller than the containers that cannot be stacked. .. In the present invention, of course, it is not necessary to transport or store unnecessary nets. Further, since the net was fixed to the paint bucket by the claws, the conventional one had a limitation on the width of the edge. However, in the present invention, since the net is not required, the width of the edge portion is not restricted, and the degree of freedom in design is improved. When it is desired to increase the strength of the container or when it is desired to have the role of a handle for taking out the container according to the present invention from the paint bucket, the width of the edge portion can be widened.

FIG. 1 is an external view showing an example of a container according to an embodiment of the present invention. 2 (a) to 2 (d) are front views showing an example of the side surface of the container in the embodiment of the present invention. FIG. 3 is an external view showing an example of a container according to an embodiment of the present invention. FIG. 4 is an external view showing a conventional container.

Hereinafter, a container having a protrusion in one embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an external view showing a container 10 according to an embodiment of the present invention.

The container 10 that can be used to hold the paint includes a top 14 having an opening 12 and an edge around the opening 12, a bottom 16 located at the bottom of the container 10, and a side portion 18. I have. The upper portion 14 is provided to increase the strength of the container 10. In the present embodiment, the strength of the container is increased by forming an edge portion around the opening 12.

The shape of the opening 12 has at least four sides, but when the shape of the opening 12 is substantially quadrangular, those corners may be chamfered. This is because when the container 10 is molded, it is easier to mold it if there are no corners. The length of one side inside the opening 12 may be 200 mm to 250 mm. Further, the length of the other side inside the opening 12 may be 150 mm to 190 mm. If the length of one side of the opening 12 is 230 mm or more, a 9-inch (229 mm) coating roller can be used. Further, if the length of one side of the opening 12 is 180 mm or more, a 7-inch (178 mm) coating roller can be used.

In the container 10, the area of the opening 12 is larger than the area of the bottom 16. Therefore, the containers 10 can be stacked, and no extra space is taken when selling or transporting the containers 10. Further, since the area of the opening 12 is larger than the area of the bottom 16, it is possible to mold the container 10 by pressing the resin once with a die.

The container 10 may have a handle portion 22. The handle 22 is used when the container 10 is placed in the paint bucket and then the container 10 is pulled out of the paint bucket. Further, in the present invention, it is possible to substitute the handle portion 22 with the upper portion 14 without providing the handle portion 22. In the conventional container, a net for adjusting the amount of paint attached to the roller is fixed to the paint bucket with a nail. However, in the present invention, the net becomes unnecessary, and it is not necessary to design the upper portion 14 of the container 10 in consideration of the claws for fixing the net. Therefore, the upper portion 14 can be formed so as to be larger than the outer shape of the opening of the paint bucket. In such cases, the top 14 may be used when pulling the container 10 out of the paint bucket.

The side portion of the container 10 has four surfaces, and one surface of the side portion 18 is provided with at least one protrusion 20. The protrusion 20 is used to adjust the amount of paint attached to a paint, for example, a coating roller, a brush, a brush, or the like.

Specifically, the user soaks the paint in the roller by immersing or rolling the roller in a container containing the paint. The roller absorbs more paint than necessary to apply the paint to the wall, etc., and if the user paints the wall etc. with the roller in this state, uneven coating or paint may fall from the roller. Highly sex. Therefore, the user can adjust the paint that has permeated into the roller by bringing the roller into contact with the protrusion 20 while rotating the roller. Therefore, the user can prevent uneven coating and the paint from falling from the rollers.

The protrusion 20 is arranged so as to be convex inside the container 10. It is preferable that the protrusion 20 has a portion where the cross section of the protrusion 20 is curved on a surface perpendicular to the direction in which the protrusion 20 extends. When the protrusion 20 has a shape having a curved portion, the force applied to the protrusion 20 can be dispersed. This curve may be represented by a function that is not discontinuous in a predetermined interval, such as an arc or a part of an ellipse. Even if the height of the protrusion (the height at which the curve is maximized from the intersection of the side surface 18 provided with the protrusion 20 on the surface perpendicular to the direction in which the protrusion 20 extends) is 5 mm to 30 mm. good.

In the embodiment shown in FIG. 1, the protrusion 20 is a series of lines bent at the top, but the protrusion 20 may be a series of lines bent at the bottom. Further, the protrusion 20 may be a plurality of bent and continuous linear shapes.

In the present embodiment of the present invention, the shape of the protrusion is not limited to the above-mentioned shape. 2 (a) to 2 (d) are views showing an example of the side surface of the container in the embodiment of the present invention.

FIG. 2A shows that the side portion 38 has a plurality of linear protrusions 30, 32, 34 that are substantially parallel to the bottom portion. Here, the distance a between the protrusions 30 and the protrusions 32 is preferably 40 mm or less. This is because if the interval a is too large, the rollers do not roll on the protrusions 30 and 32, and it becomes difficult to adjust the paint that has soaked into the rollers.

FIG. 2B is a diagram showing a state in which a part of the first protrusion 40 is sandwiched between a part of the second protrusion 42. In other words, when the first protrusion 40 and the second protrusion 42 are projected onto the side of the opening of the side surface 48 having them, a part of those projections overlaps. As shown in FIG. 2B, by arranging the protrusions 40 and 42 on the side portions 48, the roller can smoothly roll on the protrusions 40 and 42, and the paint soaked into the rollers can be adjusted. It becomes easy to do.

In the example shown in FIG. 2B, the protrusion 40 is a series of lines bent at the top, and the protrusion 42 is a series of lines bent at the bottom, but they are the opposite. There may be. Further, the protrusion 40 may be linear or may have a plurality of refracted portions. Similarly, the protrusion 42 may be linear or may have a plurality of refracted portions.

FIG. 2C is a diagram showing a state in which the first protrusion 50 sandwiches the second protrusion 52. In other words, when the first protrusion 50 and the second protrusion 52 are projected onto the side extending from the opening of the side surface 58 having them to the bottom, the projections overlap. As shown in FIG. 2C, by arranging the protrusions 50 and 52 on the side portions 58, the roller can smoothly roll on the protrusions 50 and 52, and the paint soaked into the rollers can be adjusted. It will be easier to do.

In the example shown in FIG. 2 (c), the protrusion 50 is linear, but the protrusion 50 may have at least one refracted portion. Similarly, in the example shown in FIG. 2 (c), the protrusion 52 is linear, but the protrusion 52 may have at least one refracted portion. Even when at least one of the first protrusion 50 and the second protrusion 52 is not linear, the opening of the side surface 58 having the first protrusion 50 and the second protrusion 52. When projected onto the sides extending from the portion to the bottom, the protrusions may be arranged so that the projection portions overlap.

FIG. 2D is a diagram showing endless protrusions 60 and 62. When the first projection 60 and the second projection 62 are projected onto the side of the opening of the side surface 68 having the projections 60 and 62, a part or all of the projections overlap and all of them overlap. When the first projection 50 and the second projection 52 are projected onto the side extending from the opening of the side surface 68 to the bottom, a part or all of the projections overlap. As shown in FIG. 2D, by arranging the protrusions 60 and 62 on the side portions 68, the roller can smoothly roll on the protrusions 60 and 62, and the paint soaked into the rollers can be adjusted. It will be easier to do.

Further, although the protrusions 60 and 62 shown in FIG. 2D are endless, a protrusion having an endless shape and a protrusion having an end may be used in combination.

Further, in FIGS. 2 (a) to 2 (c), a plurality of protrusions are drawn on the side surface, but for example, even if the ends of the respective protrusions are connected to form one protrusion, the figure is shown. It has the same effect as the protrusions shown in 2 (a) to (c). The protrusions shown in FIG. 2D do not have ends, but even if the protrusions shown in FIG. 2D are connected to each other, they have the same effect as the protrusions shown in FIG. 2D. ..

Even if the roller rolls smoothly on the protrusion, if the hair of the roller is longer than the height of the protrusion from the side surface, the hair of the roller is in the valley between the protrusion and the protrusion. There is a possibility of contact. Similarly, even if the roller is sponge-like, if the roller is strongly pressed against the protrusion, the roller may come into contact with the valley between the protrusions.

The container 10 described above is provided with at least one protrusion 80, 84 on one surface, but the present invention is not bound by it. That is, at least one protrusion may be provided on the other side surface.

FIG. 3 is an external view showing a container 70 according to another embodiment of the present invention.

The container 70 that can be used to hold the paint includes an opening 72 and a top 74 having an edge around the opening 72, a bottom 76 located at the bottom of the container 70, and sides 78, 82. It is equipped with. In the container 70, at least one protrusion 80, 84 is provided on the two surfaces of the side portions 78, 82. The protrusions 80, 84 are used to adjust the amount of paint attached to a paint, for example, a coating roller, a brush, a brush, or the like.

In the container 70, the directions of the protrusion 80 and the protrusion 84 are different, but the directions of the protrusion 80 and the protrusion 84 may be the same. Further, the shape of the protrusion 80 may be the shape shown in FIGS. 2A to 2D, and the shape of the protrusion 82 is shown in FIGS. 2A to 2D. It may be in shape.

In another embodiment of the invention, the container may be provided with at least one protrusion on each of the three sides. Further, in the container according to still another embodiment of the present invention, at least one protrusion may be provided on each of the four side portions.

Further, in the present invention, at least one protrusion may be provided on the bottom. Such protrusions are useful when mixing paint and solvent with a roller.

In the present invention, aluminum alloy, carbon fiber and the like can be used as the material of the container, but resin is preferable. This is because the resin is cheaper than the aluminum alloy and carbon fiber and is easy to process. Further, the container according to the present invention may be made by pressing the resin once with a die. As the resin, a thermoplastic resin may be used. Polypropylene may be used as the thermoplastic resin. This is because it has excellent chemical resistance.
