Abstract
An applicator device for high or low viscosity liquids essentially comprises a container (R) having a plunger (2) which can be operated by turning a rod (3), whereby the liquid in the container is squeezed out into an applicator brush (4). Said rod (3) is hollow and carries the brush (4) at one of its ends (3b) while the other end (3a) is immersed in the container (R). Between these ends, it passes through the plunger (2) and is in engagement therewith via a screw thread (3c). Said rod (3) is rotated by a ratchet wheel (10) controlled by a side push-button (6). The applicator device allows a viscous product such as nail varnish to be delivered, for example to a brush.
Claims12
An applicator device for viscous liquids comprising:
- a body,
- a liquid-containing container arranged in said body,
- a piston arranged in said container, said piston having a threaded aperture,
- a hollow rod having a first end, a second end opposite to said first end and a threading arranged on an outer surface, said second end extending into said container, said hollow rod passing through said piston, said threading of said hollow rod cooperating with said threaded aperture of said piston such that a rotation of said hollow rod causes an axial displacement of said piston in said container,
- a brush member arranged at said first end of said hollow rod, the rotation of said hollow rod causing expulsion of the liquid in said container toward said brush member,
- a ratchet-wheel arranged coaxial to said hollow rod and rotatively made fast to said hollow rod, said ratchet-wheel having teeth, and
- a lateral push-button for causing said ratchet-wheel to rotate, said push-button comprising two substantially parallel arms slidably mounted through an aperture in said body and extending in a direction orthogonal to an axis of said ratchet-wheel to co-operate with said teeth of said ratchet-wheel through alternate meshing and escapement of said two arms with said teeth, said two arms having teeth co-operating with said teeth of said ratchet-wheel.

- a part arranged in said body to freely slide and rotate,
- a ratchet-wheel axially made fast with said part, said ratchet-wheel having teeth, and
- a lateral push-button for causing said ratchet-wheel to rotate, said push-button comprising two substantially parallel arms slidably mounted through said body and extending in a direction orthogonal to an axis of said ratchet-wheel to co-operate with said teeth of said ratchet-wheel through alternate meshing and escapement of said two arms with said teeth, and
- said hollow rod extending through said ratchet-wheel and being mounted in a non-rotating relationship in said part, such that rotation of said part causes rotation of said hollow rod and displacement of said piston to carry liquid via said hollow rod to said brush member.
