CLAIMS

1. A paintbrush holder (1), comprising a brush-holder part (2) that is open at the top for receiving a brush, with a volume, a spout-shaped part (3) provided on a top side of the brush-receiving part, wherein a largest diameter of the spout shaped part is larger than a largest diameter of a brush to be inserted in the brush-receiving part, in which a lower

and smallest diameter of the spout-shaped part is adapted to fit the average diameter of the head of the paintbrush, wherein the volume of the brush-receiving part below the smallest diameter is larger than the volume of the brush hairs, wherein the brush-receiving part narrows with an angle of -5°-10°, wherein at least a part of the paintbrush holder comprises an elastomer (4), which elastomer is provided at the level of the smallest diameter of the spout-shaped part, which elastomer is adapted to close the volume airtight and liquid tight, and wherein the elastomer has a shore type A of 50-75, and wherein the spout-shaped part has a height such that a mass center of gravity of a paintbrush to be received falls in the paintbrush holder.

2. A paintbrush holder according to claim 1, wherein the brush-receiving part and spout-shaped part are made as one part or wherein the spout-shaped part is detachably attached to the brush-receiving part, such as by means of a screw element or clamping element (5), which screw or clamping element comprises an opening for receiving the spout-shaped part, and wherein the brush-receiving part is provided with the corresponding screw or clamping elements (6) .

3. A paintbrush holder according to any of claims 1-2, wherein the spout-shaped part is provided with a non-round part (9), which non-circular part prevents rotation of the paintbrush holder, and wherein the brush-receiving part is tapered, such as tapered with an angle b<3°.

4. A paintbrush holder according to any of claims 1-3, wherein the volume of the brush receiving part below the smallest diameter is at least 20% greater than the volume of the brush hairs, preferably at least twice as large, even better and at least four times larger, such as 5-10 times larger .

5. A paintbrush holder according to any of claims 1-4, wherein the entire holder is made of elastomer, or

wherein the holder is made of a more rigid material, such as plastic, glass, or metal, like aluminum, and the brush head is fully or partly made of elastomer.

6. A paintbrush holder according to any one of claims 1-5, wherein the elastomer has at least one of a glass transition temperature of <273K, comprising an amorphous polymer, an elastic modulus (Youngs modulus) of <5 MPa, and an elongation at break of> 100%.

7. A paintbrush holder according to any of claims 1-6, wherein the brush-receiving part is made from a polyolefin, such as polyethylene or polypropylene, and/or wherein the holder has a bottom that is wider than a top part of the holder .

8. A paintbrush holder according to any of claims 1-7, wherein the brush-receiving part has a circular cross section, or an oval cross section, or a substantially rectangular section .

9. A paintbrush holder according to any of claims 1-8, wherein the brush-receiving part has a flat bottom (8) .

10. A paintbrush holder according to one of claims 1-9, the elastomer fitting to a middle one diameter of the brush head.

11. A paintbrush holder according to one of claims 1-

10, the length being 8-20 cm, preferably 9-15 cm, such as 10- 12 cm.

12. A paintbrush holder according to one of claims 1-

11, wherein the container is injection molded.

13. A paintbrush holder according to any of claims 1-

12, wherein the spout-shaped part has a height of 1-3 cm, such as 1.5-2 cm.

14. A paintbrush holder according to any of claims 1-

13, wherein the spout-shaped part narrows under an angle g of 60-80° relative to a longitudinal axis, preferably under an angle of 65-75°, such as 68-72°.

15. An assembly comprising a paintbrush holder (1) according to any of claims 1-14 and a matching paintbrush.
