Abstract
A first embodiment of a coffee filter dispenser has a housing in which a stack of coffee filters to be dispensed are received. A plurality of resilient grippers are axially movable between a retracted and an extended position. A crank arm is connected to the resilient grippers for actuation thereof. By manipulation of the crank arm in axial and rotary directions, a single coffee filter may be dispensed from a stack of coffee filters through resilient plastic flaps in the housing. In a second embodiment, a coffee filter dispenser utilizes an axially reciprocal and rotary plunger having an adhesive foot for removing the top filter from a stack of coffee filters. The adhesive foot is radially offset from the plunger axis, and a spiral cam groove on the plunger causes the foot to be displaced radially as the plunger moves axially. In this manner, a single coffee filter may be laterally dispensed through a pivotal door in the dispenser housing.
