Abstract
A nasal spray device for dispensing a liquid from a pressurized container (R). The nasal spray device includes two juxtaposed applicators (1a, 1b), each being provided with at least one expulsion duct (10a, 10b) opening at an outer end in a spay nozzle (B) and communicating at an inner end with the container (R) with a pressurizing device (P). The applicators are fixed to a base (2) which couples them to the container (R). The nasal spray device includes a first part (I) supporting the applicators (1a, 1b) and an outer bottom skirt (11) radially clamping onto a cylindrical inner bearing surface (21) provided along a surface of a second part (II) carrying the base (2). The first and second parts (II) define bottom portions of the expulsion ducts (10a, 10b).
