Zusammenfassung:	A low waste pump follower includes a platen and a perforated member. The platen has a bottom side defining a cavity and the perforated member covers the cavity. The pump follower is driven into a container of viscous material. Material is forced through the perforated member, into the cavity, and pumped to a dispenser. When the pump follower reaches the bottom of the container, it is retracted, and the residual material present in the cavity is retained by the perforated member.
