Abstract
A hand held dispenser for dispensing foamable compositions is disclosed that is particularly useful for foam-in-place packaging systems. The hand held dispenser comprises a housing; a motor in the housing; a transmission in the housing and driven by the motor; and a valving cartridge in the housing and driven by the transmission for dispensing foamable compositions upon demand. The motor is positioned below the valving cartridge for providing a clear line of sight along the top of the housing.
