Wood grain paint brush

Abstract

To provide a paint brush which can easily perform painting showing a grain-tuned gradation.SOLUTION: A paint brush related to the present invention comprises a handle 1 having a bristle bundle 2 at the tip, where the handle 1 comprises two or more pressure containers 3 capable of containing a liquid paint. Even if pressure is applied to each of the pressure containers 3 containing paint, the handle 1 can support each of the pressure containers 3 with no deformation to discharge paint to the bristle bundle 2 by reducing the pressure container 3 by directly pressing the pressure container 3 with finger tips of a hand gripping the handle 1, thus enabling paint with no supply of paint to the bristle bundle 2 from other than the pressure containers 3. The pressure containers 3 contain paint of different colors from each other and vary tints of paint applied to the bristle bundle 2 by selecting the pressure containers 3 to perform pressing, or by varying adjustments of pressing force for each pressure container 3.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a brush for wood-grain painting.

Background Art

[0002] When using wood for an interior, for example, in the case of a single-piece board exceeding 10 m, due to its size, it is often difficult to carry it into a building, deliver it to a customer, or install it indoors. Also, from the perspectives of the depletion of forest resources, environmental considerations, and the reduction of material costs and distribution costs, there is a social trend to avoid using wood. [[ID=1)]]

[0003] In view of the above, the inventor of the present application considered applying a wood-grain coating to wallpaper to replace the use of wood. For example, as wood used for interiors, there is a high demand for African Sapele (Entandrophragma cylindricum), which has a high-class feel comparable to that of expensive Mahogany (Khaya mahagoni) in terms of its texture. Therefore, the inventor of the present application considered applying a Sapele-like coating to wallpaper. Sapele is a broad-leaved tree of the Meliaceae family and is a wood with beautiful wood grain.

[0004] During the above consideration, it was considered difficult to reproduce a natural-looking Sapele pattern on wallpaper simply by applying paints of a plurality of different colors. For many woods with high demand for interiors, not only limited to the Sapele pattern but also for others, simply painting with different colors is not sufficient to imitate their texture, and it is often necessary to express the gradation between different colors.

[0005] <000002)]] However, the expression of wood texture by the above gradation requires a skilled person with painting skills, and the quality of the painting largely depends on the skill of the operator performing the painting. Furthermore, conventional methods involve preparing multiple paint cans containing different colored paints, dipping a brush into each can sequentially to mix the colors, and then applying the paint. However, even for skilled painters, it is extremely difficult to properly apply the two types of paint to the brush in a single stroke to create the aforementioned gradient that mimics wood grain (wood texture).

[0006] On the other hand, recently, a method has been proposed in which a wood grain pattern is formed on the surface of a metal plate by applying paint, instead of using actual wood (Patent Document 1). Patent Document 1 proposes forming a wood grain pattern by using two different types of paint, and the wood grain pattern is formed on the surface of a metal plate, which is the material to be painted, by applying each of the above-mentioned paints using a brush.

[0007] Specifically, Patent Document 1 describes a coating method in which a first paint of a base color for a wood grain pattern is applied to the surface of a member to be coated, and a second paint of a different color from the first paint and diluted with a solvent to a degree of 100 to 2000 times that of the first paint is applied to the surface of the member to be coated with the first paint using a brush with frayed bristles that create a textured surface, thereby forming a wood grain pattern on the surface of the member to be coated with the first paint.

[0008] When painting wallpaper, baked enamel coating is not possible. However, by using the application method described in Patent Document 1 for painting the wallpaper, applying the first paint to the wallpaper with a regular brush, and then having a skilled person apply the diluted second paint with a brush that has a staggered, uneven bristle pattern, it may be possible to obtain a result similar to the gradient described above. However, the coating method described in Patent Document 1 requires sequentially applying two or more paints of different colors, and does not aim to achieve a gradient in a single coat.

[0009] Furthermore, even before considering how to achieve a gradient in a single coat, as mentioned above, the conventional method of dipping a brush into a paint can or a container of diluted paint to adhere the paint to the brush makes it difficult to control the amount of paint that adheres to the bristles. The adhesion ratio between different colored paints also varies depending on the worker, or even the same worker from time to time, making it impossible to reliably obtain the desired gradient.

[0010] On the other hand, in order to improve efficiency in painting, a method has been proposed and is being used that involves preparing a separate container for storing paint, such as a tank, and connecting the brush to the container with a pipe, thereby supplying paint from the container to the brush (Patent Documents 2 and 3).

[0011] However, connecting the brush to the separate tank via a pipe would make handling the brush connected to the pipe cumbersome, and would also require a compressor or other means of pressurizing the paint from the tank to the brush. Thus, the devices shown in Patent Documents 2 and 3 result in bulky and heavy devices with an enlarged structure around the brush, hindering the light and agile brushwork of conventional methods.

[0012] Unlike Patent Documents 2 and 3, there is also a proposal to form a compression hemisphere on the brush to draw in and discharge paint, thereby supplying paint to the bristles without providing a compressor or other pressurized feeding means (Patent Document 4). However, the structure of the compression hemisphere is unclear, and furthermore, it requires a separate paint can and a supply pipe connecting the paint can and the brush, making it cumbersome to handle, which is not significantly different from Patent Documents 2 and 3.

[0013] Ultimately, if we were to improve the applicator shown in Patent Documents 2-4 to enable painting with two colors of paint, we would have to prepare two of each of the above-mentioned tanks (paint cans) and pipes, which would further increase the size of the already bulky applicator and make it even more cumbersome to handle. Of course, in order to obtain a gradient between two colors, in addition to the improvements mentioned above, it is also necessary to appropriately change the supply ratio of both paints to the brush. However, none of the patent documents 2 to 4, which do not presuppose multi-color painting, show any specific means for changing the supply ratio, that is, for obtaining the desired gradient in a single coat.

[0014] In addition, there are also painting tools that eliminate the configuration of supplying paint to the brush by connecting the brush and the paint storage means such as a tank with a pipe (Patent Document 5). The paint applicator shown in Patent Document 5 is a self-contained applicator that does not require an external supply of paint. It involves attaching a bristle bundle at the tip of a brush to the mouth of a paint container, and by gripping the container itself, the container becomes a handle, while squeezing the container to supply paint to the bristle bundle. This eliminates the need for the above-mentioned configuration in which a separate paint storage means and the brush are connected by a pipe, and the paint is supplied from the storage means to the brush by the compressor.

[0015] However, as described above, the device shown in Patent Document 5 requires the paint container itself to be gripped and compressed to transfer the paint to the bristles, making it difficult to perform the usual brushwork by gripping a stable, non-deforming handle. For example, as the amount of paint in the container decreases with use, the container gradually loses its rigidity, and the feel when gripped changes, creating an uncomfortable sensation and making it difficult to handle like a conventional brush.

[0016] Furthermore, the applicator shown in Patent Document 5 does not use two different colored paints, and naturally, there is no way to change the ratio of the two paints supplied to the hair bundle in order to obtain a gradient between the two paints in a single coat. Therefore, if the applicator shown in Patent Document 5, like the applicators shown in Patent Documents 2 to 4 above, were to be made capable of painting with two types of paint, it would require the applicator to be equipped with two containers and further require a means to change the ratio of the paints supplied from both containers. In particular, if the applicator in Patent Document 5 is equipped with two containers in which the paint containers also serve as handles, it would become impossible to even grip the containers, let alone compress or deform them, making it impossible to appropriately change the ratio of the two types of paint supplied to the hair bundle.

[0017] As mentioned above, none of the applicators described in Patent Documents 2 to 5 attempt to perform multi-color painting without compromising the feel of using a conventional brush, and it is difficult to create a brush from Patent Documents 1 to 5 that can easily create a desired gradient between multiple colors in a single stroke.

[0019] Ultimately, in the conventional painting method of successively dipping ordinary brushes into a paint can for painting, it is not easy for an inexperienced operator to perform painting that imitates the texture of wood with multiple colors at once. As seen in Patent Document 1, measures such as repeatedly applying paint to the painting target surface for each color are required. Even if multiple layers are applied with different colors, it is necessary to apply the subsequent color on the painting target surface before the previously applied paint dries while predicting the finish, and it is not always possible to easily obtain the desired natural gradation. If one were to attempt to apply paint to the painting target surface with multiple colors using the paint applicators of Patent Documents 2 to 5 without modification, one would be forced to change containers for each color to be stored or compelled to perform painting using multiple applicators alternately. Regarding the gradation that imitates the texture of wood, as described above, the paint applicators of Patent Documents 2 to 5 do not have the technique of obtaining it in one stroke, that is, in one application, and require the measure of applying layers for each color, which is no different from the conventional painting method for an inexperienced operator. [[ID=!]]

[0020] The present invention has been made based on the inventor's ingenious idea, and aims to provide a brush for wood grain painting that can easily reproduce a gradation between multiple colors that imitates the texture of wood in one application on wallpaper without impairing the usability of conventional brushes.

Means for Solving the Problem

[0021] The present invention relates to a wood grain-pattern painting brush having a handle and a tuft of bristles provided at the tip of the handle, wherein two or more pressing containers are provided on the handle, each of the pressing containers can accommodate a liquid coating agent, and by pressing the pressing container with a fingertip, the volume of the pressing container can be reduced at least while the pressing is being performed, and even when pressure is applied to each of the pressing containers containing the coating agent, the handle can support each of the pressing containers without deformation, and by directly pressing the pressing container with the fingertip of the hand holding the handle to reduce the pressing container and discharging the coating agent contained therein toward the tuft of bristles, the coating agent can be supplied to the tuft of bristles, enabling painting without receiving supply of the coating agent to the tuft of bristles from other than the painting brush, i.e., other than the pressing container, and at least one of the pressing containers contains a coating agent of a color different from the coating agent contained in other pressing containers, and by selecting the pressing container to perform the pressing or by changing the amount of pressing force for each pressing container, a wood grain-pattern painting brush is provided that can change the color tone of the coating agent applied to the tuft of bristles. In addition, the above coating agent includes, in addition to paints in a broad sense, solvents for paints. Also, color includes not only chromatic colors but also achromatic colors and transparency. For example, the present invention includes cases where different chromatic paints are accommodated in each pressing container, and also cases where a chromatic paint is accommodated in one pressing container and a transparent diluent is accommodated in the other pressing container, and gradation is obtained by adjusting the dilution of the paint with the diluent. The above paints in a broad sense include paints in a narrow sense and varnishes. In the present invention, the pressing container includes a housing portion for housing the coating agent and an opening for discharging the coating agent housed in the housing portion, the handle includes a fixing member for fixing the pressing container, and each of the pressing containers is detachably attached to the handle with the opening facing the tuft of bristles by the fixing member, and a wood grain-pattern painting brush can be provided that allows the pressing container to be removed from the handle to fill the coating agent or to exchange it with another pressing container filled with the coating agent. Furthermore, in the present invention, each of the pressing containers is at least one of a dropper, pipette, tube, or syringe, and the tip of the handle on which the bristle bundle is provided is formed to be wider than the rear side of the handle to match the width of the bristles of the bristle bundle, forming the head of the handle, and the rear side of the handle can be grasped as a handle, and on one side of the head having a width corresponding to the width of the bristles, at least two recesses are provided substantially parallel to each other as receiving parts for the pressing container, each extending in the longitudinal direction of the handle and receiving at least a part of the pressing container, and a strip-shaped or plate-shaped member is attached to the handle as the fixing member that crosses each of the receiving parts, and the fixing member restrains the pressing container so that each of the pressing containers received in the receiving part does not fall out of the receiving part, and by removing at least one end of the fixing member from the handle, the pressing container can be removed from the receiving part, thus providing a wood grain finish paint brush. [Effects of the Invention]

[0022] In the wood-grain finish painting tool of the present invention, by applying force with the fingertips of the hand holding the handle to at least two pressure containers detachably attached to the handle, the paint can be applied to the bristles, and by manipulating the handle, the bristles can be brought into contact with the surface to be painted, such as wallpaper, and the paint can be applied to the surface to be painted. In particular, by filling each of the two pressing containers with paints of different colors, and then, while painting the surface to be painted with the paint brush, by selecting one of the pressing containers and applying pressure, or by changing the strength of the pressure applied to each of the pressing containers, the color of the paint applied to the bristles can be changed, making it relatively easy to create a desired gradient on the surface to be painted. For example, by placing dark brown paint in one pressing container and ochre paint in the other, and then selecting which pressing container to use or pressing both containers with different strengths, it becomes easy to gradually change the color of the paint, thereby creating a wood-grain-like gradient on the surface to be painted. Furthermore, in this invention, by supplying the paint agent to the bristles using a pressing container detachably attached to the handle, we have been able to provide a brush that can supply paint agent to the bristles with a simple structure. As described above, in this invention, by adjusting the pressure of the fingertips on the multiple pressure containers attached to the brush, the mixing ratio of two or more colors can be freely adjusted on the bristles, making it extremely easy to draw a gradient suitable for mimicking wood grain on the surface to be painted. Therefore, it is particularly suitable for applying sapele-like (imitating sapele wood) paint. Furthermore, this invention makes it possible to supply the coating agent using only the brush, making the brush easy to handle and eliminating the need for large-scale peripheral equipment.

[Modes for carrying out the invention]

[0024] Embodiments of the present invention will be described below with reference to the drawings. For the sake of explanation, in the drawings, U is the top, S is the bottom, F is the front, B is the rear, L is the left, and R is the right (please refer to these in particular when describing the dimensions of each part of the brush).

[0025] (Basic configuration) This paint brush comprises a handle 1 held by the user (painter), a bundle of bristles 2 called a ball or bristle ball, with its base fixed to the tip of the handle 1, two pressure containers 3 that hold paints of different colors, and fixing members 4 that detachably secure each of the pressure containers 3 to the handle 1 (Figures 1, 2(A)(B), and 3). The following describes each component in turn.

[0026] (Handle 1 and hair bundle 2) The handle 1 comprises a grip 11 (handle) to be held by the user and a head 12 (head). The material for handle 1 can be wood or resin, or a lightweight metal such as aluminum, with dimensions similar to those of a standard brush. In the longitudinal direction of the handle 1 (the vertical direction in Figure 1(A) and (B) where the brush is shown vertically), the handle 11 constitutes the rear side of the handle 1 (the upper side of the handle 1 as shown in Figure 1(A) and (B)), and the head 12 constitutes the tip of the handle 1 (the lower end of the handle 1 as shown in Figure 1).

[0027] A bundle of hair 2 is attached to the jaw 13 at the tip of the head 12 (sandwiched between the jaws 13), and the bundle of hair 2 is fixed to the head 12 by wrapping and tightening a strip of fastening material 14, such as a metal plate or tree bark. For fixing the bundle of hair 2 as described above, cherry bark can also be used as the fastening material 14. In this example, a metal plate was used as the fastening material 14.

[0028] The handle 11 has a length w1 and thickness (width w2 and thickness w3) suitable for gripping. With the longitudinal direction of the handle 1 as the vertical direction, the head 12 has a thickness (front and back F, B) that is approximately the same size as or slightly larger than the diameter of the handle 11, and a width (left and right L, R) that is larger than the diameter of the handle 11. The thickness of the head 12 is such that it can form the jaw 13 and the receiving portion 15 for receiving the pressure container 3, and the width of the head 12 is greater than the width w2 of the handle 11.

[0029] Furthermore, the width w4 of the head 12 is the same as or slightly larger than the width wa (maximum width) of the hair bundle 2 (especially the root 21), i.e., the hair width. The thickness of the head 12 is such that at the tip of the head 12, the thickness includes the hair bundle 2 (especially the root 21) between the jaw 13. Therefore, the thickness at the tip of the head 12 is greater than the thickness wb of the hair bundle 2 (the root 21). The receiving portion 15 described above is a recess formed in a parallel manner on one side of the head 12, i.e., the front, with a width corresponding to the width of the bristles, and each recess extends in the longitudinal direction of the brush (Figures 3 and 4(A)).

[0030] Each of the receiving portions 15 can receive a portion of the pressing container 3 (Figures 1 and 2(A) and 2(B)). The receiving portion 15 exposes at least the portion of the receiving pressing container 3 that is subjected to pressure. In this example, a portion of the back side of the pressing container 3 is received by the receiving portion 15, while the front side of the pressing container 3 is exposed. The fixing member 4, which will be described in detail later, covers the portion of the front side and prevents the pressing container 3 from falling out of the receiving portion 15. Furthermore, by forming the receiving portions 15 to be approximately parallel to each other, the long pressing containers 3 can be arranged in roughly parallel positions.

[0031] The width wa of the hair bundle 2 is naturally greater than the distance between the openings 31 of both pressing containers 3. The lower limit of the distance between the openings 31 of both pressing containers 3 is regulated by the diameter of the parts of the pressing container 3 other than the openings 31, but the upper limit of this distance is set to the distance at which the paint is discharged onto the hair bundle 2 so that the paint of different colors discharged from both openings 31 can be applied in an appropriate gradient (Figures 1(A), 5, and 6).

[0032] If the two nozzles 31 are too far apart, the paint dispensed onto the bristle bundle 2 will not mix within the bristle bundle 2, or it will take a long time for them to mix. The distance between the two nozzles 31 should be set according to the absorption capacity of the paint on the bristle bundle 2 (the spread of the paint within the bristle bundle 2), although this will vary depending on the viscosity and amount of paint dispensed and the material of the bristle bundle 2. A pressure container 3 with dimensions that can ensure this distance should be used.

[0033] Of course, if the amount of paint dispensed by pressing the pressure container 3 (the amount of paint dispensed as described above) is small, it will not be possible to apply enough paint to the bristle bundle 2. However, the spacing between the two openings 31 should be set so that when both pressure containers 3, which are full of paint, are pressed as hard as possible with a finger to dispense the paint, the paint from both containers will mix within the bristle bundle.

[0034] Hair bundle 2 can be formed from a known material. Specifically, the bristles of bristle bundle 2 can be made from common materials such as animal-derived materials like horsehair, pig hair, goat hair, weasel hair, and human hair, plant-derived materials like plant fibers, and synthetic fibers. In particular, the bristles should be selected to be optimal for the paint used. The length of the bristles of bristle bundle 2 should also be the standard length used for painting. However, the length of the bristles of bristle bundle 2 should be such that it can receive the paint supplied from the pressure container 3 and apply it appropriately to the surface to be painted.

[0035] Furthermore, the bristle bundle 2 should be composed of bristles of appropriate thickness and water absorption rate depending on the type and viscosity of the paint used. For example, if water-based paint is used, synthetic fibers such as PBT, PET, or PP, which have low water absorption rates, are suitable. Synthetic fibers have superior abrasion resistance compared to animal hair, while animal hair has superior elasticity and flexibility. The material of the bristles should be selected according to the paint used and the wood grain pattern to be drawn.

[0036] The dimensions of each part of the handle 1 are the same as those of a typical commercially available brush, except for the thickness of the head 12, so that it can be held and used for painting without any discomfort (Figure 1(A)(B)). A typical commercially available brush is a brush in which you hold the handle, attach the bristles to a paint can or paint tray containing paint, and apply the paint contained in the bristles to the surface to be painted. Regarding the dimensions of each part of the handle 1, specifically, it is preferable that the maximum values ​​for each are as follows: for the handle 11, the length w1 is 5 cm or more and 30 cm or less; the width w2 is 1 cm or more and 3 cm or less; and the thickness w3 is 0.5 cm or more and 3 cm or less. For the head 12, it is preferable that the length w6 in the longitudinal direction is 4 cm or more and 12 cm or less; the width w4 is 4 cm or more and 15 cm or less; and the thickness w5 is 0.5 cm or more and 3 cm or less.

[0037] Although it varies depending on the coating agent used, generally, the length of the bristles of bristle bundle 2 should be 2 to 15 cm, and the width of the bristles should be 4 cm to 15 cm, provided that at least the base of bristle bundle 2 does not exceed the width of the head 12.

[0038] Regarding the handle 11, it is preferable that the length w1 be 8 cm or more and 15 cm or less, the width w2 be 1.5 cm or more and 2.5 cm or less, and the thickness w3 be 0.5 cm or more and 2 cm or less. Regarding the head 12, it is preferable that the length w6 in the longitudinal direction be 5 cm or more and 10 cm or less, the width w4 be 5 cm or more and 10 cm or less, and the thickness w5 be 15 cm or more and 2.5 cm or less.

[0039] Furthermore, the length of the bristles of the bristle bundle 2 is preferably 4 to 12 cm, and the bristle width is preferably 4 cm to 12 cm, provided that at least the base 21 of the bristle bundle 2 does not exceed the width of the head 12. In particular, when using water-based paints or paints with relatively low viscosity, it is preferable to set the bristle width within the above range. However, each part of the brush 1 may deviate from the above numerical range, as long as the paint can be applied properly and the desired gradient can be created.

[0040] (Pressure container 3) Each of the pressing containers 3 is a long container that compresses the contained coating agent by pressing, reducing its volume at least during the pressing process, and then discharges it (Figures 1, 2(A)(B), 3, and 4(A)). Each pressing container 3 is attached to the handle 1 and positioned along the longitudinal direction of the handle 1. That is, by being received by the receiving portion 15 of the head 12, the pressing containers 3 are positioned along the longitudinal direction of the handle 1, with the opening 31 facing the bristle bundle 2. Each of the pressing containers 3 contains the above-mentioned liquid coating agent.

[0041] As mentioned above, the pressing containers 3 each contain paints of different colors. For example, one pressing container 3 may contain dark-colored paints such as brown, dark brown, or red, while the other pressing container 3 may contain light-colored paints such as orange, tangerine, yellow, skin tone, or ochre. However, the transparent diluent may be considered a light color, and the orange, tangerine, yellow, skin tone, and ochre colors described above as light colors may also be considered dark colors, with the paints being stored separately in each pressure container 3 according to their shade. Furthermore, regarding the different colors mentioned above, it is not limited to the dark and light colors listed above; other colors can also be used.

[0042] In this example, the pressing container 3 is a dropper formed entirely of flexible resin. The pressing container 3 comprises a cylindrical storage section 33 for containing the coating agent, a pressing section 34 which serves as a knob and extends from the rear end of the storage section 33, and a tubular section 32 which extends from the front end of the storage section 33. The opening at the tip of the tubular section 32 is a nozzle 31 for dispensing the coating agent contained in the storage section 33. The dropper may be formed from an opaque resin, but forming it from a transparent or translucent resin makes it easier and more convenient to check the remaining amount and color of the paint contained within. A commercially available dropper can be used as the pressure container 3.

[0043] By positioning the pressing container 3, i.e., the dropper housing 33, on the receiving portion 15 of the handle 1, the tubular portion 32 is made to have a length that allows the opening 31 to be brought close to the hair bundle 2. In this example, the receiving portion 33 of the dropper is received by the receiving portion 15, and at least the rear portion of the pressing portion 34 protrudes from the receiving portion 34 (Figures 1 and 5).

[0044] The painter grasps the handle 11 with the ring finger f4, little finger f5, and thumb f1 of their hand, presses the pressing part 34 of one pressing container 3 with their index finger f2, and presses the pressing part 34 of the other pressing container 3 with their middle finger f3. The index finger f2 and middle finger f3 can each press the pressing part 34 against the front of the head 12. However, the rear ends of each pressing part 34 that protrude backward from the shoulder 16 between the handle 11 and the head 12, i.e., the rear end of the head 12, may also be grasped and pressed with the fingertip of the thumb f1 wrapped around the handle 11 and the index finger f2 or middle finger f3.

[0045] When using the brush, the brush is held at an angle with the front side (front side) of the brush to which the pressure container 3 is attached facing upwards, so that the tip of the bristle bundle 2 comes into contact with the surface to be painted k (Figure 4). The pressure container 3 positions the opening of its tubular portion 32 between the base 21 and the tip 22 of the bristle bundle 2, in the direction in which the bristles of the bristle bundle 2 grow. In this state where the brush is held at an angle, the tip of the tubular portion 32 abuts against the upper side (front side in Figure 1) of the bristle bundle 2, allowing the paint agent to seep into the bristle bundle 2 from the opening 31 (Figure 4(B)(C)).

[0046] However, as long as the brush is angled as shown in Figures 4(B) and 4(C) and the tubular portion 32 is positioned above the bristle bundle 2, it is sufficient that the paint can be dripped from the opening 31 onto the bristle bundle and adhered to the bristle bundle, even if the opening 31 is separated from the bristle bundle 22. Furthermore, the tip of the tubular portion 32 may be designed to fit into the bristle bundle 22. For example, the receiving portion 15 can be formed to gradually become shallower from bottom to top (from the tip end to the rear end), so that when the brush is viewed from the side, the pressure container 3 is positioned at an angle to the brush, allowing the tip of the tubular portion 32 to be inserted into the bristle bundle 2 (not shown).

[0047] Alternatively, instead of forming the receiving portion 15 to gradually become shallower from bottom to top, a suitable spacer may be placed between the rear side of the receiving portion 15 and the pressing container 3 so that the rear side of the pressing container 3 is held and angled against the brush as described above, or the tubular portion 34 of the pressing container 3 may be curved toward the bristle bundle 2 (not shown).

[0048] However, whether the tip of the tubular part 34 is not inserted into the bristle bundle 2 as described above, or whether it is inserted into the bristle bundle 2 from the beginning, in either case, it is necessary to position the tubular part 34 so that, during use, the bristle bundle 2 bends to conform to the surface to be painted k, preventing the tip of the tubular part 32 from piercing the bristle bundle 2 and hitting the surface to be painted. In particular, even if the tip of the tubular part 34 does not hit the surface to be painted at the beginning of use, it is desirable to position the tubular part 32 so that the bristles 22 do not fray or the bristle bundle 2 lose their stiffness during use, preventing the tip of the tubular part 34 from hitting the surface to be painted.

[0049] (Fixing member 4) The fixing member 4 is a band-like body provided on the head portion 12 so as to cross the receiving portion 15 (Figures 1, 2(A)(B), 3-6). This band can be made of a soft resin, leather, or cloth. One end of the fixing member 4, which is a band, is fixed to the head 12 as a fixing part 41 with a fastener such as a screw or nail. The other end of the fixing member 4, which crosses the receiving part 15, is detachably fixed to the head 12. With the dropper received in the receiving portion 15 and the other end of the band fixed to the head portion 12, the band crosses the housing portion 33 of each dropper located in the receiving portion 13, but exposes the pressing portion 34 (without covering it).

[0050] In this example, a locking portion 42 is provided at the other end of the fixing member 4, and a locking portion 43 that can detachably lock the locking portion 42 is fixed to the head portion 12. Specifically, the locking portion 42 can be either the male or female part of the snap, and the locking portion 43 can be the other of the male or female part of the snap. In the illustrated example, a fixing portion 41 is provided on one of the left and right sides of the head 12, and a locking portion 43 is provided on the other left and right side of the head 12. However, in addition to employing a snap mechanism, the fixing member 4 may also use a well-known buckle to close the above-mentioned band-shaped body.

[0051] By opening one end of the fixing member 4, i.e., the locking portion 42 side, the dropper, i.e., the pressing container 4, can be placed in or removed from the receiving portion 15 (Figures 3 and 4(A)). The dropper can be removed from the handle 11 and filled with paint, or replaced with another dropper filled with paint.

[0052] (Example of use) The user, i.e., the painter, attaches each of the press containers 3 filled with paint to the brush, grips the handle 11 as a handle, and applies the paint by bringing the bristle bundle 2 into contact with the surface k to be painted (Figures 4(B)(C), 5 and 6). By using the fingertips of the hand h that is grasping the handle 11 to select and press the pressing container 3, or by changing the amount of pressure applied to each pressing container 3, the color of the coating agent applied to the hair bundle 2 can be changed (Figure 6).

[0053] In this example, when changing the gradient towards the darker color, the pressing part 34 of the pressing container 3 containing the dark colored paint is pressed firmly with the middle finger f3 towards the head 12 to dispense a large amount of dark colored paint from the opening 31 to the hair bundle 2, while the pressing part 34 of the pressing container 3 containing the light colored paint is pressed with the index finger f3 towards the head 12 with less force than the middle finger press to dispense a smaller amount of light colored paint from the opening 31 to the hair bundle 2 (Figures 5 and 6). To change the gradient towards lighter colors, lightly press the pressing part 34 of the pressing container 3 containing the dark-colored paint toward the head 12 with your middle finger f3 to dispense a small amount of the dark-colored paint from the opening 31 to the hair bundle 2. At the same time, press the pressing part 34 of the pressing container 3 containing the light-colored paint toward the head 12 with your index finger f3 with more force than the middle finger press to dispense a large amount of the light-colored paint from the opening 31 to the hair bundle 2. If a gradient is not applied, only one of the pressing containers 3 needs to be pressed.

[0054] (Example of change) Although the fixing member 4 described above is exemplified as a flexible strip (strip-shaped body), it is also possible to use a plate-shaped body that can be opened and closed relative to the brush 1. Alternatively, for example, a deformable molded product of synthetic resin may be used as the fixing member 4, in which a recess is formed on the inner surface, i.e., the surface facing the pressing container 3, to serve as a sub-receiving part 44 that receives the portion of the outer circumferential surface of the pressing container 3 that is exposed from the receiving part 15 (Figure 7(A)(B)).

[0055] Furthermore, a leaf spring that crosses each receiving portion 15, has one end fixed to the brush 1, and is curved in a semicircular shape can be used as the fixing member 4 (Figure 7(C)(D)). By inserting the pressing container 3 between the leaf spring and the receiving portion 15, the pressing container 3 can be attached to the handle 1 of the pressing container 3. The leaf spring should not press the pressing container 3 too hard so that paint is not discharged from the pressing container 3 during and after insertion.

[0056] Although not shown in the illustration, instead of providing the opening and closing fixing member 4 and the receiving portion 15 on the handle 1, a pocket, i.e., a hole with the vertical direction U and S as the depth direction, can be provided on the head 12 as the fixing member 4, into which the pressing container 3 can be inserted from the handle 11 side toward the head 12. The tip side of the pocket (the lower side in Figures 1(A) and (B)) is provided with a through hole with a smaller inner diameter than the pocket, which allows the tubular portion 32 of the inserted pressing container 3 to be exposed toward the hair bundle 22 side, and the pressing portion 34 of the inserted pressing container 3 should be exposed from the pocket so that it can be pressed. The above-mentioned pockets may be provided in a number corresponding to the number of pressure containers 3, or one pocket large enough to accommodate both pressure containers 3 may be provided in the head 12.

[0057] In addition to the dropper described above, the pressing container 3 may also employ a pipette (not shown) that has a pressing part 34 made of a rubber bag called a nipple and the rest of the part made of glass.

[0058] Furthermore, the pressing container 3 may be a tube commonly used for toothpaste, paints, or cosmetics, and the tube may be pre-filled with the coating agent (Figure 2(C)). The tube may be a laminated tube made of a flexible plastic or other resin, or a metal tube made of aluminum or other metal. In the above tube, the housing portion 33 also serves as the aforementioned pressing portion 34, and the coating agent can be dispensed by pressing the housing portion 33.

[0059] Furthermore, the pressure container 3 can be a syringe with the injection needle removed from the tubular part 32. For example, it can also be carried out using a pressure container 3 similar to a syringe, consisting of a syringe (outer barrel) which is the housing part 33 and a plunger (pushing part) which is the pressure part 34 (Figure 2(D)).

[0060] In the examples described above, two pressing containers 3 are attached to the handle 1, but it is also possible to attach three or more pressing containers 3 to the handle 1, as long as they can be properly pressed during painting. When three or more pressing containers 3 are attached to the handle 1, three or more receiving parts 15 should be provided according to the number of containers attached.

[0061] However, in the range in which the pressing portion 34 of the pressing container 3 can be exposed, the width of the fixing member 4 extending laterally to the left and right and the width in the direction intersecting it (band width) can be increased to ensure stable holding of the pressing container 3, and the receiving portion 15 on the handle 1 may not be provided. Alternatively, even if the receiving portion 15 is provided, it can be implemented by providing one receiving portion 15 with a width that can accommodate all the pressing containers 3 without partitions separating adjacent pressing containers 3. In addition, instead of the receiving portion 15, the head 12 may be provided with raised portions that protrude on the left and right sides of the pressing container 3, or projections that protrude on the left and right sides of the pressing container 3. The above-mentioned protrusions may be formed by shaping the brush or by grinding the brush, but they may also be formed by driving a separate nail or pin into the brush. The wood grain paint brush according to the present invention is suitable for painting sapele patterns, but it can also be used for painting wood grain patterns with gradients other than sapele.
