ABSTRACT:
A means for separating one coffee filter from a pack of filters employing a small device having one or more piercing elements. The handle or holder for the piercing elements fits comfortably in the hand. The strength, length, shape and size of the piercing means should be such that the elements penetrate the thickness of one paper filter without causing undue tearing, cutting or destruction of the filters while being able to withstand the lifting pressures exerted when breaking the suction and fiber adhesion of the top filter from the adjoining filter. A sheath for protecting the piercing elements may be in the form of a scoop or measuring receptacle.
