Abstract
A dispensing bottle-top 10 for bottles for products of liquid or viscous consistency includes a bottle-top body (20) adapted to be mounted on a bottle and including a feed cavity (13) and a top piece (30) adapted to be moved relative to this body between an inactive configuration in which a product dispensing orifice (35) is blocked and an active configuration in which this dispensing orifice (35) is exposed to the outside and communicates with the feed cavity (13). This bottle-top has a lateral wall that is advantageously cylindrical and is formed by the body 20 and, in said inactive configuration, an upper wall consisting entirely of the upper wall of the top part 30. This cylindrical body and this top part have complementary part-spherical surfaces adapted to slide one along the other with a relative movement and being connected by complementary retaining and guiding elements that remain hidden by this top part in each of the active and inactive configurations thereof. The dispensing orifice 35 is in one of the sliding surfaces.
