Patent number: 8061393Abstract: A filling method for filling a reservoir (10) of variable working volume with a fluid, the method being characterized in that the reservoir (10) is firstly emptied of any content, such that its working volume is substantially zero, and the fluid is then injected into the reservoir, thereby increasing the working volume of the reservoir (10).Type: GrantFiled: April 10, 2006Date of Patent: November 22, 2011Assignee: AirlesssystemsInventor: Alain Behar

Patent number: 6997353Abstract: The invention concerns a fluid product dispenser comprising a gas reservoir (10), a fluid product reservoir (20), a dispensing head comprising at least one dispensing orifice (30). The gas reservoir and the fluid product reservoir are connected to the head so that their contents can communicate with the at least one dispensing orifice. The dispenser comprises a movable actuation wall (14; 24) to simultaneously generate a pressure state in the gas and fluid product reservoirs and thus force the fluid product and the gas through the the at least one dispensing orifice.Type: GrantFiled: March 26, 2003Date of Patent: February 14, 2006Assignee: AirlesssystemsInventors: Laurent Decottignies, Alain Behar
