Patent ID: 8881921

Claim:
A bottle-top comprising: a bottle-top body adapted to be mounted on a bottle, wherein: said body includes a feed cavity and a top part, the top part is adapted to be moved relative to the body between an inactive configuration wherein a product dispensing orifice is blocked, and an active configuration wherein said dispensing orifice is exposed to an outside and communicates with the feed cavity, the bottle-top comprises a lateral wall formed by the body and, in said inactive configuration, the bottle top comprises an upper wall formed by an upper wall of the top part, the body comprises a concave part-spherical sliding surface which includes a main slot having a plane of symmetry, and the top part comprises a complementary convex part-spherical sliding surface and two parallel flanks that are symmetrical to the plane of symmetry of the main slot and project relative to said convex part-spherical sliding surface, said flanks comprising clipping detents adapted to engage and retain said flanks in said main slot, one of said sliding surfaces comprises said dispensing orifice, said dispensing orifice being symmetrical to the plane of symmetry of the main slot, the dimension of the main slot along the plane of symmetry is adapted so that the main slot remains hidden by the top part in both the inactive and active configurations, and the part-spherical sliding surfaces are adapted to slide one along the other in a relative movement and are connected by complementary retaining and guiding elements that remain hidden by the top part in both the active and inactive configurations.
