A device for dispensing a viscous fluid product, including a pump having an inlet; an outlet; a cylinder; a piston in the cylinder; and a piston rod attached to the piston with its first end being exposed. The pump pumps viscous fluid product from a container to the outlet when the inlet is submerged in the viscous fluid product and the piston rod is axially moved relative to the cylinder. The device further includes a handle attached to the piston rod; a nozzle rotatably mounted on the handle around a rotation axis, in fluid communication with the outlet, and having a discharge orifice offset from the rotation axis; and a mechanism for rotating the nozzle around the rotation axis when the piston rod is axially moved relative the cylinder so that the discharge orifice moves in a circular pattern for dispensing the viscous liquid product in a substantially helical pattern.
