Abstract
A fluid dispenser comprising: two sheets (1, 1′), at least one of which is deformable, the two sheets forming a fluid reservoir (15) between them, said at least one deformable sheet defining a deformable actuating wall so as to reduce the volume of the reservoir, the reservoir (15) advantageously being provided with resilient means (4) urging the reservoir towards its maximum volume; and a dispensing piece (2) fixed in leaktight manner between the two sheets (1, 1′) and defining a dispensing orifice (24) via which the fluid from the reservoir is dispensed; said fluid dispensing being characterized in that the reservoir (15) is defined by an inner first sealing line (12) and the outer peripheral edges of the sheets are sealed together along an outer second sealing line (10) which surrounds the inner first sealing line, the two sealing lines (10, 12) defining between them at least one non-sealed-together zone (11) in which the sheets are not sealed together.
