Abstract: A fluid dispenser head (T) including a spray wall (26) that is perforated with a network of holes (O) through which the fluid under pressure passes so as to be sprayed in small droplets; the dispenser head being characterized in that the network of holes (O) comprises at least two series of holes (O), with the holes (O) of a given series presenting holes that are substantially identical in size, and with the holes (O) of different series presenting holes that are different in size, such that one series of holes (O) generates a spray of small droplets with droplet sizes that define a first Gaussian distribution, while another series of holes (O) generates a spray of small droplets with droplet sizes that define a second Gaussian distribution that is offset relative to the first Gaussian distribution, thus producing a complex spray having at least two distinct Gaussian distributions.

Abstract: A method for producing a containing system for a liquid dispenser having a dimensionally stable outer container and a collapsible inner container, in the form of a pouch, arranged within the outer container. The method includes starting from the outer container, at least one layer of a pouch material being applied to an inner wall of the outer container. For this purpose, the pouch material is applied in the form of a liquid or powder to the inner wall, where, after solidifying or fusing, it forms a ply of a wall, of the inner container. The ply detaches from the inner wall of the outer container when the inner container collapses.
