Abstract
Fluid dispenser head for mounting on a variable-volume fluid reservoir that has a movable wall. The head has a dispenser orifice, a sealing closure pin that closes the dispenser orifice, a resilient mechanism for urging the pin against the orifice, and a fluid inlet in communication with the reservoir. The head further includes a flexible differential membrane respectively defining bottom and top surface areas that are subjected to opposite pressure forces that are exerted by the fluid under pressure, the bottom surface area being substantially smaller than the top surface area, the closure member being formed by the flexible membrane.
