Patent ID: 6840409

Claim:
Packaging for a fluid such as a cream or a paste, the packaging comprising a hollow body ( 1 ) and stopper means ( 2 ), the hollow body ( 1 ) being a flexible tube defined by a wall ( 10 ) suitable for being subjected at least locally to reversible deformation and terminating in a neck ( 11 ) pierced by an opening ( 100 ) centered on a main axis (X), and the stopper means ( 2 ) comprise an annular base ( 20 ) fixed to the opening ( 100 ) in order to define therein a dispenser orifice ( 200 ) for the fluid, and a stopper ( 21 ) having a closure finger ( 210 ), said stopper being connected to the base ( 20 ) via a hinge link ( 25 ) and being selectively movable relative to the base ( 20 ) by turning through an angle of more than 90° between a first position in which the finger closes the dispenser orifice and a second position in which the orifice is released, the packaging being characterized in that the neck ( 11 ) is formed by the wall ( 10 ) of the tube which converges on the main axis (X) going towards the opening ( 100 ), in that the neck ( 11 ) presents a determined minimum radius (R) in a longitudinal plane (L) containing the main axis (X), in that the hollow body ( 1 ) presents a determined circumference (C) in a plane (T) extending across the main axis (X) and situated halfway between the ends ( 110 , 120 ) of the hollow body ( 1 ), in that the ratio (C/R) of the determined circumference (C) over the minimum radius (R) is not greater than five, and in that the base ( 20 ) is engaged in the opening ( 100 ), putting the neck ( 11 ) under radial tension, and is prevented from moving relative to the opening along the main axis (X).
