Pump Dispenser and Method of Manufacturing a Pump Dispenser

摘要

A manually actuated pump dispenser (210) has a dispenser main body (212, 214) including a first pump chamber (228) for a first fluid. An actuator (216) is mounted to the dispenser main body for movement towards and away from the dispenser main body. A flexible wall member (266) extends between the dispenser main body and the actuator to define a second pump chamber (268) between the dispenser main body and the actuator for a second fluid. The flexible wall member (266) is attached at one end to the actuator or to a part of the dispenser main body and has a distal end (266A) comprising a collar (265) which is mounted to the other of the actuator and a part of the dispenser main body to form a seal therewith. The flexible wall member may be formed integrally with the actuator or the part of the dispenser main body and the collar, for example by using bi-injection techniques. A method of manufacturing the pump dispenser is also disclosed.
