Head for dispensing fluid material

A fluid dispenser system, comprising a fluid dispenser, comprising a dispenser member (P) and a fluid dispenser head (T) including a spray wall that is perforated with a network of holes (O) through which a fluid under pressure passes so as to be sprayed in small droplets, the dispenser member configured to generate pressure on the fluid lying in the range of 2 bars to 13 bars;

• and
• a fluid reservoir on which the dispenser member is mounted;
• wherein 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 same in size, and with the holes (O) of different series presenting holes that are different in size from the size of the holes in the given series, such that one series of holes (O) is configured to generate a spray of small droplets with droplet sizes that follow a first Gaussian distribution, while another series of holes (O) generates a spray of small droplets with droplet sizes that follow 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;
• and
• wherein the fluid reservoir contains a perfume or pharmaceutical, and wherein the dispenser member is a pump or a valve;
• wherein the size of the holes of the two series of holes lies in the range of 5 μm to 30 μm;
• and
• wherein the dispenser member is a pump configured to generate internal pressure on the fluid lying in the range of 2 bars to 7 bars.
