<p>A fluid dispenser including a fluid reservoir including a neck with a constricted opening that communicates with an inside volume; and a dispenser member including a fluid inlet that is provided with a dip tube, the dip tube provided with a substantially-plane flexible sheet having shape memory. The sheet presents a transverse dimension, in the direction that is perpendicular to the dip tube, that is greater than the dimension of the constricted opening, such that the sheet must be caused to take up a deformed configuration in order to pass through the neck, and must then relax into a substantially-plane rest configuration inside the inside volume. The sheet presents a bottom edge having a portion that, in the rest configuration, penetrates into the constricted opening to initiate the deformation of the sheet, so as to bring it subsequently into its deformed configuration.</p> |
