Abstract
The invention concerns a device comprising a pourer, adapted to be mounted on the container neck, and an assembly forming a cover adapted to be mounted on said neck and comprising a cap mobile between a first position where it isolates the neck and the pourer from outside and a second position providing access to the neck and the pourer. The assembly forming a cover comprises two catching string rims (411, 412) extending radially inwards from a ring (41), one first string rim (411) being adapted to be engaged with an external flange (26) of the neck (2) while a second string rim (412) is adapted to be engaged with an external flange (36) of the pourer (3), said string rims (411, 412) defining between them a volume (V) for receiving the flanges (26, 36).
Claims10
Device for closing a container (1) provided with a neck (2), said device comprising a pourer (3), adapted to be mounted on said neck, and an assembly (4) forming cover adapted to be mounted on said neck and comprising a cap (43) mobile between a first position where it isolates said neck and said pourer from the outside and a second position where it allows access to said neck and to said pourer, characterized in that said assembly forming a cover comprises two catching string rims (411, 412), extending radially inwards from a ring (41), a first rim (411) being adapted to be engaged with an external flange (26) of said neck, while a second rim (412) is adapted to be engaged with an external flange (36) of said pourer, said first and second rims defining between them a volume (V) for receiving said flanges.
Device according to one of the preceding claims, characterized in that said first rim (411) forms a surface (411a) inclined with respect to a central axis (X4-X′4) of said device, said surface being flared in the direction of the body (11) of said container (1).
Device according to one of the preceding claims, characterized in that said first and second rims each form a surface (411b, 412b) substantially perpendicular to said central axis (X4-X′4) of said device.
Device according to one of the preceding claims, characterized in that said flange (36) of said pourer (3) extends radially outwards from an edge (34) of a skirt (33) formed by said pourer and adapted to cover said neck (2).
Device according to one of the preceding claims, characterized in that said ring (41) extends, opposite said cap (43), by a skirt (45) adapted to come into abutment against the outer surface of a part (28) of said container (1).
Device according to one of the preceding claims, characterized in that said pourer (3) is disposed at least partially inside said neck (2) and in that said cap (43) is provided with a skirt (433) extending, in said first position and from an inner surface (432) of said cap, up to the level of an edge (22) of said neck, the skirt being adapted to exert, in said first position and against an inner radial surface (3 la) of the pourer, a force (F6) tending to apply said pourer against said edge.
Container for liquid (1), particularly bottle made of plastics material, equipped with a closure device (2-4) according to one of the preceding claims.
