Abstract
Abstract An apparatus for dispensing a single cup-shaped paper coffee filter from the top of a stack of filters 100 is described which includes a base 11 having upper and lower surface, 11a and 11b in which the upper surface is for splaying the stack of filters. A compression plate 13 supported by a pivot pin 14 is mounted adjacent the upper surface of the base for splaying the stack of coffee filters, and a backstop 17 is mounted adjacent to the compression plate on the top of the base for bending the stack of coffee filters enabling a single coffee filter to be dispensed from the stack. The base includes suction cups for mounting the apparatus to a hard surface while dispensing.

Claim 1
Independent Claim
204 words
A dispensing apparatus for a stack of cup-shaped coffee filters having a bottom connected to vertically fluted sides leading to a lip around a circumference of the stack of filters where the lip is above the bottom of the stack when the stack is mounted in the apparatus and wherein an uppermost filter is to be manually removed from the apparatus which comprises: (a) a base having an upper and lower surface wherein the upper surface provides a horizontal dispensing platform for supporting the bottom of the stack of filters; and (b) a compression plate having a rear portion and a front portion with a recess in the front portion of the compression plate over the stack of filters and with the rear portion of the plate including means for pivotably mounting said plate on the upper surface of the platform and with arms extending from the front portion of the compression plate with the recess between the arms, said arms having ends which engage opposed portions of the lip of the stack of filters, means including the arms to splay the stack of filters against the upper surface of the base to facilitate manual removal of a single uppermost filter from the stack.
