2117308 9311059 PCTABS00022 A dispenser is disclosed which includes a container (10) having a base (14), a cylindrical side wall (12) and a lid (32). A piston (24) is arranged within the container between component (20) and an air space (26) between the piston (24) and lid (32). A diaphragm (50) is arranged within the air space (26) and is sealed to the container between a rim (13) of the container and a rim (33) of the lid (32) so that an enclosed volume (60) is defined between the diaphragm (50) and the lid (32). A rod (38) extending between the base and lid and passing through the piston and diaphragm is provided to reinforce the container. The lid (32) includes an air inlet (36) for allowing compressed air to enter the enclosed volume (60) to expand the diaphragm to thereby move the piston to dispense the component (20) from the dispenser. In a further embodiment the diaphragm is replaced by an air bag located within the air space and bearing against the piston and lid.
