Mixer systems 200 are provided. A representative mixer system 200 includes a power circuit 105 that powers the mixer apparatus 200; a motor 110 that is electrically coupled and powered by the power circuit 105; and a rotating structure 115 that is mechanically coupled to the motor 110, which rotates the rotating structure 115. The rotating structure 115 includes container chambers 230a,b that a container 240a,b is aligned therein, wherein the rotation of the container 240a,b mixes substances that are contained in the container 240a,b to have a homogeneous or heterogeneous mixture.

The invention relates to a system for preparing a formulation in a container, comprising an agitating device, said agitating device including means for creating a conical depression within the formulation inside said container. Said system is arranged to prepare a formulation consisting of a nail polish inside a bottle.

A mixer for fluid products, including a base, a support structure mounted on the base and rotatable about a first axis of rotation, and a housing structure having a housing for a container of fluid products. The housing structure is mounted on the support structure at a radial distance from the first axis, and can be rotated about a second axis of rotation which is at a radial distance from the first axis. A motor is mounted on the base for transmitting a rotational movement to the support structure about the first axis a first transmission. A second transmission transmits the rotational movement to the housing structure about the second axis. The housing for a fluid product container is at a radial distance from the second axis so as to impart, during use, a combined epicyclic movement to at least one container accommodated on the housing structure.

Some embodiments relate to a mixing device for fluid products contained in containers is described, comprising a plurality of cups configured to house the containers of the liquids to be mixed inside them and operated by means of a train of gears by motor means in so as to rotate simultaneously with a revolution motion around a vertical axis and with a rotation motion around an axis of the cups which is inclined by an angle with respect to the vertical axis, the mixing device also comprising a counterweight fixed to a support of the cups on the opposite side with respect to the vertical axis.

A mixing machine for continuously mixing powder material in a liquid flow, including a mixing body including: a mixing section in which a rotor is rotatably mounted, a liquid inlet section located above the mixing section, and a powder inlet section located above the liquid inlet section The powder inlet section is movable between a closed position and an open position, such that in the closed position the powder inlet section closes an upper edge of the liquid inlet section, and in the open position the powder inlet section is detached from the upper edge of the liquid inlet section.
