Patent ID: 7780041

Claim:
A device for atomizing a fluid product, comprising: a reservoir containing the fluid product and air, the reservoir including a wall having at least one deformable area; a dip tube which communicates selectively or permanently with an atomizing aperture that atomizes the fluid product in response to pressure exerted on the deformable area, wherein the dip tube comprises: a first end to guide the fluid product from the dip tube to the atomizing aperture; a second end, disposed at an end opposite the first end, through which the fluid product enters the dip tube from the reservoir; and an air passage that allows at least part of the air contained in the reservoir to mix with the product conveyed by the dip tube, the air passage being positioned between the first end and the second end of the dip tube such that when the fluid product is initially filled in the reservoir, a volume of the reservoir below the air passage is greater than a volume of the fluid in all positions of the reservoir.
