<p>The device has a mouthpiece (20) mounted on a reservoir (10) containing a product (P) and air, and comprising a spraying orifice (21) communicating with the reservoir via a dip tube (30). An air passage (31), permitting the air to be introduced in the tube when the product rises again in the tube, is formed in lateral wall of the tube. The position of the air passage is chosen such that, before the initial usage of the device and in partially deformed position of a bulged zone (11) of the reservoir, the passage is at the exterior of the product irrespective of the position of the reservoir. The reservoir presents a plane wall (12) opposite to the bulged zone (11).</p> |
