Abstract
The device (1) includes an applicator brush (4) including a rod (5) provided with applicator means (A) such as bristles (6). The rod (5) is carried by a cap (7) intended to close the neck, and this cap is integrally joined to a sheath (9) capable of surrounding the rod (5). The rod (5) is mounted displaceably in the sheath (9) with respect to the cap (7), and at its end remote from the cap, the sheath (9) includes a restriction (11), through which the applicator means (A) of the brush can pass. The rod (5) of the brush includes an enlargement (12) arranged to come into contact with the restriction (11) by gravity, when the brush (4) is oriented downward, so as to retain the rod and close the restriction. Toward the cap, the sheath (9) includes at least one opening (14, 15) allowing liquid to enter the sheath when the bottle, closed by the cap, is inverted, and a free space (16) exists between the inside surface of the sheath and the outer surface of the rod to form a reservoir for the liquid. The length (L) of the sheath is greater than that (1) of the rod, such that the rod (5) can retract inside the sheath (9), which assures the opening of the restriction.
