A dispenser mechanism is provided for removing a filter paper from a stack of filter papers without disturbing other papers of the stack. A gripper member is manually rotated to rotate the topmost filter paper relative to the next lower paper of the stack. Surfaces of the uppermost and next lower papers rub against each other to break area surface contact. Peripheral corrugations on the papers may cam over each other to break the area surface contact. Then, the paper can readily be lifted and removed.

A dispenser of individual coffee filter papers from a stack of such papers, wherein each filter paper has a circular plan area including a central flat area and a radially corrugated annular peripheral area, the papers being stacked with their central areas in close contact, with their peripheral areas extending outwardly and upwardly and with the corrugations thereof in nesting relation, said dispenser comprising: an open-topped container having an inner wall surface defining a cross-sectional area sized in relation to the circular plan area of the filter paper stack that frictional engagement between the inner wall surface and the outer peripheral edge surfaces of the papers is minimized, whereby the filter papers may be rotated about a central axis of the central flat areas of the papers without distortion of the papers by engagement with the container inner wall surface, and whereby individual filter papers may be drawn upwardly through the open top of the container without substantially deforming the papers, a dust cover disposed in the container atop the stack of filters papers, and having thereon manual engagement means for facilitating grasping of the dust cover, a central post element extending downwardly from the dust cover and having an end face engagable with the central flat area of the uppermost paper in the filter paper stack, and a contact adhesive material on the lower face of the post element to exert a gripper force on the uppermost filter paper, whereby upon manual rotation of the dust cover the uppermost paper in the stack is rotated to cause the corrugations thereof to ride over the corrugations of the next lower paper so that the corrugations of the two papers are out of phase and registration and not adhered, thus to permit ready and convenient lifting of the uppermost paper from the stack by lifting of the dust cover.
