A novel fluid supply cup comprises a flexible liner integral with a container having an opening and a vent. A novel method of manufacturing a lined container comprises the steps of molding a container having a vented thick-walled portion and an integral flexible thin-walled liner, and folding the thin-walled liner into the thick-walled portion. Finally, a novel method of applying a fluid comprises the steps of providing a flexible liner integral with a container having an opening and a vent, loading fluid into the liner, engaging the container with a fluid applicator, flowing the fluid out of the liner into the fluid applicator, collapsing the liner, and flowing the fluid of the fluid applicator.
