Patent ID: 7549599

Claim:
A device for dispensing a viscous fluid product from a standing container, the device comprising: a pump connectable to the container and comprising: a cylinder having a first end surface and a second end surface which is opposite to the first end surface; a piston disposed in the cylinder with freedom of axial movement between a first working position and a second working position; a hollow piston rod fixedly attached to the piston and extending through the second end surface of the cylinder with a first end thereof being disposed outside the cylinder, wherein the piston dividing the cylinder into a first working space on a side of the piston facing away from the piston rod and a second working space on a side of the piston facing the piston rod, and the hollow piston rod defines a third working space therein; a first fluid connection for connecting the first working space with an inlet leading outside of the cylinder; a first non-return valve in the first fluid connection; a second fluid connection which connects the first working space with the third working space; and a second non-return valve in the second fluid connection, wherein the pump is operable to pump the viscous fluid product from the container to the first working space when the inlet of the first fluid connection is submerged in the viscous fluid product and the piston is moved in a first direction from the first working position toward the second working position, and to pump the viscous fluid product from the first working space to the third working space when the piston is moved in a second direction from the second working position toward the first working position; a handle fixedly attached to the first end of the hollow piston rod facilitating manual operation of the pump; a nozzle rotatably mounted on the handle around an axis of rotation, the nozzle having a discharge orifice which is radially outset from the axis of rotation; a third fluid connection which connects the third working space with the nozzle; and a rotating mechanism for rotating the nozzle around the axis of rotation when the piston is moved in the second direction so that the discharge orifice moves in a circular pattern for dispensing the viscous liquid product in a substantially helical pattern when the viscous liquid product flows through the discharge orifice.
