Cylindrical containers for paint or the like of the type having a hollow container body, a cap, a brush attached to the cap, and an agitator for mixing the contents of the container is improved by constructing the agitator as a tubular hollow member that is mounted within the container so as to surround the brush attached to the cap and be axially displaceable relative thereto, the agitator member having ribs that are fashioned in the manner of blades of a fan wheel and are uniformly distributed about the periphery of the agitator member with its outer edges located on an imaginary cylinder, the diameter of which is slightly smaller than the inner diameter of the container body. According to preferred embodiments, the ribs of the agitator can either be twisted helically with respect to the longitudinal axis of the hollow member or can be straight blade vanes inclined at an angle to the longitudinal axis of the agitator. According to a particularly advantageous embodiment, the axial length of the outer edges located on the imaginary cylinder are longer than the length of the tube so that the leading edges of the ribs extend inwardly at an angle with respect to the longitudinal axis from the outer edges to the hollow tube, thereby only providing localized points at the junction of the outer edges and leading edges where contacts can occur with the paint container, and the agitator cannot become stuck to the container bottom after a relatively long resting period thereon.
Cylindrical container for paint or the like, comprising a hollow container body, a cap, a brush attached to the cap, and an agitator constructed as a tubular hollow member guided in the container in the axial direction of the latter, surrounding said brush attached to the cap, and having radially outwardly projecting ribs, characterized in that the ribs are fashioned in the manner of blades of a fan wheel and are uniformly distributed about the periphery of the hollow member, wherein the outer edges of the ribs are located on an imaginary cylinder, the diameter of which is slightly smaller than the inner diameter of the container body, and also characterized in that the ribs are twisted helically with respect to the longitudinal axis of the hollow member.
Cylindrical container for paint or the like, comprising a hollow container body, a cap, a brush attached to the cap, and an agitator constructed as a tubular hollow member guided in the container in the axial direction of the latter, surrounding said brush attached to the cap, and having radially outwardly projecting ribs, characterized in that the ribs are fashioned in the manner of blades of a fan wheel and are uniformly distributed about the periphery of the hollow member, wherein the outer edges of the ribs are located on an imaginary cylinder, the diameter of which is slightly smaller than the inner diameter of the container body, and also characterized in that four ribs are provided, each rib having two leading sides one on each end thereof, said two leading sides being mutually offset in the peripheral direction, but extending perpendicularly to a tangent placed on the outer diameter of the tube.
