  • Patent number: 4121726
    Abstract: An apparatus for dispensing cup-shaped paper coffee filters from the top of a nested stack of such filters includes a box for storing and retaining the stack, a lever connected by a hinge to the lid of the box, apparatus for moving the lever to engage the top filter of the stack, and flexible plastic fingers for holding all of the filters except the top one in place as the lever engages the top filter and removes it from the stack. The lid of the box is hinged so that the box can be opened to remove the top filter from the end of the lever. Once the lever has engaged the top filter, the end of the lever is moved away from the axis of the filter stack. Lifting the lid simultaneously imparts an axially upward component to the motion of the lever, so that the lever both separates the top filter from the stack and lifts it. The filter can then be easily removed from the end of the lever.
