FIELD: personal use articles.
SUBSTANCE: bottle with a threaded neck comprises a dosing device (4, 9) for discharging the product inside the said bottle, and the said dosing device (4, 9) comprises a) a cap (4) screwed onto the threaded neck of the said bottle with a substantially tubular element (6) comprising a lower end (61) which protrudes inwards of the bottle neck, and the said lower end is closed by a lower wall (7), and a collar (14) connected to the upper part of the said tubular element by the tear-off ring (12); b) a hollow piston (9) inserted into the tubular element (6), and the piston comprises the open lower end (91) and a head (92). The said hollow piston is adapted to pierce the said lower wall (7) after removal of the collar (14) together with the tear-off ring (12); and the said hollow piston together with the lower wall (7) of the tubular element (6) forms a chamber containing the product intended for release into the said bottle; and the lower end (91) of the hollow piston (9) has a substantially angled profile relative to the plane formed by the lower wall (7), and there are the means (69, 99) which are adapted to stop the movement of the hollow piston (9) before the full detaching of the lower wall (7) and for prevention of rotation of the hollow piston (9) at the end of the movement.
EFFECT: improvement of the design.
