Container for a fluid product, and dispenser using such a container

Abstract

A fluid reservoir including a bottom and a duct that defines an opening, a sealing ball being engaged in the duct in such a manner as to close the opening hermetically, the ball being movable by an external thrust member in such a manner as to cause the ball to fall by gravity to the bottom of the reservoir so that the opening is thus unblocked. The duct is connected to a dip tube that extends into the proximity of the bottom of the reservoir, the duct presenting a diameter that is smaller than the diameter of the dip tube, the ball being in leaktight engagement in the duct before being pushed into the dip tube in which it falls freely to the bottom of the reservoir.
