Applicator dispenser of a paste cosmetic product, typically a mascara
An applicator dispenser includes a body forming a reservoir for the cosmetic product provided with a neck threaded on the outside, a sidewall and a bottom, an applicator having a head threaded on the inside forming a gripping element, an axial rod fixed at its upper end to the head and at its lower end to an application element, a wiper having an upper part fixing the wiper to said neck, and a lower narrowed part designed to wipe the application element. The wiper has an intermediate axial connecting part, which together with the upper and lower narrowed part form a single piece.

3. The applicator dispenser according to claim 2 in which the height H ER of said lower narrowed part ( 41 ) of said wiper ( 4 , 4 ′) is such that H ER /H E is less than 0.5 and typically less than 0.2.
4. The applicator dispenser according to claim 2 in which said distance d is equal to at least H A +H D , where H D is the unscrewing height of said head ( 30 ) of the applicator ( 3 ) with respect to said neck ( 20 ), said distance d typically being equal to H A +H D 30 1 mm.
5. The applicator dispenser according to claim 2 in which the axial height H ES of said upper part ( 40 ) of said wiper ( 4 , 4 ′) is substantially equal to the height H G of said neck ( 20 ) and typically less than 15 mm.
6. The applicator dispenser according to claim 1 in which the height H ER of said lower narrowed part ( 41 ) of said wiper ( 4 , 4 ′) is such that H ER /H E is less than 0.5 and typically less than 0.2.
7. The applicator dispenser according to claim 6 in which said distance d is equal to at least H A +H D , where H D is the unscrewing height of said head ( 30 ) of the applicator ( 3 ) with respect to said neck ( 20 ), said distance d typically being equal to H A +H D 30 1 mm.
8. The applicator dispenser according to claim 6 in which the axial height H ES of said upper part ( 40 ) of said wiper ( 4 , 4 ′) is substantially equal to the height H G of said neck ( 20 ) and typically less than 15 mm.
9. The applicator dispenser according to claim 1 in which said distance d is equal to at least H A +H D , where H D is the unscrewing height of said head ( 30 ) of the applicator ( 3 ) with respect to said neck ( 20 ), said distance d typically being equal to H A +H D+ 1 mm.
10. The applicator dispenser according to claim 9 in which the axial height H ES of said upper part ( 40 ) of said wiper ( 4 , 4 ′) is substantially equal to the height H G of said neck ( 20 ) and typically less than 15 mm.
11. The applicator dispenser according to claim 1 in which the axial height H ES of said upper part ( 40 ) of said wiper ( 4 , 4 ′) is substantially equal to the height H G of said neck ( 20 ) and typically less than 15 mm.
12. The applicator dispenser according to claim 1 in which said wiper ( 4 , 4 ′) is fixed to said neck ( 20 ), typically irreversibly by a click fitting means ( 43 ) or by gluing or by welding.
13. The applicator dispenser according to claim 1 in which said intermediate part ( 42 ) of said wiper ( 4 , 4 ′) has a circular section with an inside diameter D I , varying from 3 mm to 5 mm, and in which said lower narrowed part ( 41 ) of said wiper ( 4 , 4 ′) has an orifice diameter D R varying from 2 mm to 7 mm, such that D I /D R is equal to at least 1.5.
