Abstract
A container for storing and dispensing a liquid product includes a pump operated by a reciprocable control member and associated with a pneumatic servo system. The actuation is achieved by supply of gas pressure, for example, from a reservoir of gas at a pressure of the order of 5 bars, and this is used to actuate the control member of the pump, for example a stepped piston incorporating a pressure multiplying effect. Much higher operating forces on the reciprocable control member can be achieved with this system than were possible by purely manual operation of the valve control member.
