Fluid dispenser

摘要

A fluid dispenser including a fluid reservoir containing fluid; a fluid suction chamber of variable volume including an extraction and application space that varies between a minimum volume and a maximum volume; a dip tube that connects the reservoir to the suction chamber at an orifice; a suction mechanism for sucking, during a suction stage, fluid from the reservoir into the chamber through the orifice; and an extractor and applicator member that defines, in part, the suction chamber and the suction mechanism, and further the extraction and application space; wherein the sliding of the slidable sleeve over the stationary stem does not involve any resilient driving force.

1. A fluid dispenser comprising:
a fluid reservoir containing fluid; a fluid suction chamber of variable volume comprising an extraction and application space that presents a volume that varies between a minimum volume when the suction chamber presents a minimum volume, and a maximum volume when the suction chamber presents a maximum volume; a dip tube that connects the reservoir to the suction chamber at an orifice; suction means for sucking, during a suction stage, fluid from the reservoir into the chamber through the orifice; an extractor and applicator member that defines, in part, the suction chamber and the suction means, the extractor and applicator member defining the extraction and application space; a handle to be gripped by a user; and a stationary stem secured to the handle and a slidable sleeve mounted in slidable manner on the stationary stem so as to form the extraction and application space, wherein the sliding of the slidable sleeve on the stationary stem varies the volume of the extraction and application space; and wherein the sliding of the slidable sleeve over the stationary stem does not involve any resilient driving force.
