    Abstract

    The invention relates to a paintbrush holder (1), comprising a brush-receiving part (2) that is open at the top for receiving a brush, with a volume, a spout-shaped part (3) provided on an upper side of the brush-receiving part, wherein a largest diameter of the spout-shaped part is larger than a largest diameter of a paintbrush to be received in the brush holder, wherein a lower and smallest diameter of the spout-shaped part fits the diameter of the head of the paintbrush, the volume of the brush-receiving part below the smallest diameter is larger than the volume of the brush hairs, in which at least a part of the paintbrush holder comprises an elastomer (4), which elastomer is provided at the smallest diameter of the spout-shaped part, which elastomer is adapted for sealing the volume in a fluid-tight manner, and in which the spout-shaped part has a height such that a mass center of gravity (5) of a paintbrush to be received, falls into the paintbrush holder. In another embodiment of the invention, the holder consists of more rigid material like plastic, glass or metal like aluminum and the brush head consists fully or partly of an elastomer.
