Sampling-type spraying device

摘要

A dispenser device for dispensing a fluid substance in spray form, said device comprising a reservoir (13) containing the fluid substance to be dispensed, and a spray orifice (16), said reservoir (13) including at least one actuating wall (131) that can be deformed by applying a pressing force (F) so as to reduce the internal volume of the reservoir (13) and thus to exert a pressure on the fluid substance so as to deliver it through the spray orifice (16), said dispenser device being characterized in that said at least one actuating wall (131) has a predetermined threshold of resistance to deformation that must be overcome in order to deform it.
