Abstract
A shutter member for a fluid dispenser member, the shutter member having a substantially rigid base body and an elastically deformable diaphragm, the body and the diaphragm being made of materials that are chemically compatible such that the material of the diaphragm adheres to the material of the body, the body defining an anchor zone and a fluid-passing zone. The diaphragm adheres to the anchor zone and extends over the fluid-passing zone, the fluid-passing zone including an interface that is secured to the fluid-passing zone but that does not adhere to the diaphragm, thereby defining an outlet channel for fluid between the interface and the diaphragm in the presence of fluid under pressure.
