Abstract

The nail varnish applicator comprises a preferably cylindrical body, one of the ends of which is fitted with a dispenser for varnish contained in a reservoir and another end being adapted to receive a finger. A dose of varnish is sent to soak a brush, the spread of the brush being controlled by two pincers which follow the profile of the fingernail of an inserted fingernail to delimit the region to be varnished. The body is wholly closed by doors that are released on inserting the finger. The brush has an arched and resilient back for its ends to follow the edges of pincers that follow the nail contour. The back of the brush can also be made up of various displaceable elements with bristles that partially overlap one another. The brush is covered by a casing, removable by one of rotation and axial displacement. The varnish is applied upon displacement of the nail with respect to the brush, when either element stays in place.

Claims

1. A fingernail varnish applicator, comprising:

a cylindrical body having one end shaped to connect to a source of nail varnish and an opposite end dimensioned to receive a user'"'"'s finger;

a brush fitted with bristles with an adjustable spread for applying a dose of nail varnish from the source of nail varnish to a fingernail of the user'"'"'s finger, the fingernail having a contour;

a pair of pincers positioned to contact the user'"'"'s received finger, said pincers having a portion which compresses the spread of said bristles in accordance with the contour of the fingernail;

a hingeably mounted door for obstructing said opposite end of said cylindrical body;

a locking device for normally biasing said door to obstruct said opposite end of said cylindrical body, said locking device being released by the user'"'"'s finger that is to be varnished;

a pumping device positioned to engage the user'"'"'s received finger and mounted to move with the finger as it is inserted for advancing the dose of nail varnish to said bristles, said pumping device being coupled to said brush so as to orient said brush with respect to the user'"'"'s received finger; and

a casing for covering said bristles when the nail varnish applicator is not in use comprising one of a stub and a complementary helical slot and a displaceable casing having a hingeably mounted cap, said casing being displaced in response to the insertion of the user'"'"'s finger by one of rotation and axial displacement, said casing returning to an undisplaced state in response to the withdrawal of the user'"'"'s finger.

2. A fingernail varnish applicator as in claim 1, wherein said brush has an arched and resilient back portion, and said pincers include front edges which follow the fingernail contour as the user'"'"'s finger is inserted into and removed from said body

3. A fingernail varnish applicator as in claim 2, wherein said pumping device further includes a spring biased axial rod and said locking device includes a double element push-button having a first and a second element, said first element being coupled to said door and being displaceable by force of the user'"'"'s fingernail whereby said door is unlocked and said second element is engaged by the user'"'"'s received finger which presses against said spring biased axial rod thereby displacing said spring biased axial rod and causing said pumping device to dispense the dose of nail varnish.

4. A fingernail varnish applicator as in claim 3, wherein said brush is shaped to guide the dose of nail varnish from said pumping device to said bristles, and wherein said pumping device includes a dispenser chamber intermediate said source of nail varnish and said brush for dispensing the dose of nail varnish to soak said bristles as the finger is inserted into said body, said dispenser chamber being replenished from said source of nail varnish by pump action of said axial rod when the finger is withdrawn from said body and said axial rod returns to an undisplaced state.

5. A fingernail varnish applicator as in claim 3, wherein each of said bristles has one end mounted radially in said arched and resilient back portion of said brush and has a curved free end, said arched and resilient back portion including several displaceable elements so that said bristles occupy more than a transverse plane and project from different displaceable elements thereby overlapping each other in part in order to sweep and adjust to the overall fingernail surface.

6. A nail varnish applicator as in claim 2, wherein said brush is shaped to guide the dose of nail varnish from said pumping device to said bristles, and wherein said pumping device includes a dispenser chamber intermediate said source of nail varnish and said brush for dispensing the dose of nail varnish to soak said bristles as the finger is inserted into said body, said dispenser chamber being replenished from said source of nail varnish by pump action of said axial rod when the finger is withdrawn from said body and said axial rod returns to an undisplaced state.

7. A nail varnish applicator as in claim 6, wherein each of said bristles has one end mounted radially in said arched and resilient back portion of said brush and has a curved free end, said arched and resilient back portion including several displaceable elements so that said bristles occupy more than a transverse plane and project from different displaceable elements thereby overlapping each other in part in order to sweep and adjust to the overall fingernail surface.

8. A fingernail varnish applicator as in claim 1, wherein each of said bristles has one end mounted radially in said arched and resilient back portion of said brush and has a curved free end, said arched and resilient back portion including several displaceable elements so that said bristles occupy more than a transverse plane and project from different displaceable elements thereby overlapping each other in part in order to sweep and adjust to the overall fingernail surface.

9. A fingernail varnish applicator, comprising:

a substantially cylindrical body having one end shaped to connect a source of nail varnish and another end dimensioned to receive a user'"'"'s finger, said body having a longitudinal slot;

a brush having one end fitted with bristles with an adjustable spread for applying a dose of nail varnish from the source of nail varnish to a fingernail of the user'"'"'s finger, the fingernail having a contour;

a push-button dispenser handle slideably mounted in said longitudinal slot and connected to said brush;

a pair of pincers positioned to contact the user'"'"'s received finger, each of said pincers including a portion which compresses the spread of said bristles in response to the contour of the fingernail;

a sloped sluice biased so that the fingernail is obliged to be located on said pincers so that when said push-button dispenser handle is displaced in said longitudinal slot, said brush is displaced so as to varnish the inserted fingernail;

a view hole disposed above said sloped sluice;

at least one hingeably mounted door for obstructing said another end of said substantially cylindrical body; and

a locking device for normally biasing said door to obstruct said another end of said substantially cylindrical body, said locking device being released by the user'"'"'s finger that is to be varnished.

10. A fingernail varnish applicator as in claim 9, wherein each of said bristles has one end mounted radially in said arched and resilient back portion of said brush and has a curved free end, said arched and resilient back portion including several displaceable elements so that said bristles occupy more than a transverse plane and project from different displaceable elements thereby overlapping each other in part in order to sweep and adjust to the overall fingernail surface.

11. A fingernail varnish applicator, comprising:

a body shaped to connect to a source of nail varnish and dimensioned to receive a user'"'"'s finger;

a brush having one end fitted with bristles with an adjustable spread for applying a dose of nail varnish from the source of nail varnish to a fingernail of the user'"'"'s finger, the fingernail having a contour;
