Claim 1
Independent Claim
171 words
Tobacco smoke filter element adapted to be used with an outer wrap, said element comprising a porous filter body having an outer side wall and end walls characterized in that said filter body defines a single pair of first and second notch means, said notch means extending from a surface of said outer side wall into said body, said first notch means being located adjacent one end of said filter element and terminating short of the other end thereof and said second notch means being located adjacent the other end of said filter element and terminating short of said one end, said first and second notch means being disposed, respectively, on opposite sides of the longitudinal axis of said filter element so that upon drawing smoke into the filter element a pressure differential is created between the first notch means and second notch means to cause a portion of the smoke to flow generally diagonally through the filter element from the region of one notch means toward the other notch means.

Tobacco smoke filter element adapted to be used with an outer wrap, said element comprising a porous filter body having an outer side wall and end walls characterized in that said filter body defines a single pair of first and second notch means, said notch means extending from a surface of said outer side wall into said body, said first notch means being located adjacent one end of said filter element and terminating short of the other end thereof and said second notch means being located adjacent the other end of said filter element and terminating short of said one end, said first and second notch means being disposed, respectively, on opposite sides of the longitudinal axis of said filter element so that upon drawing smoke into the filter element a pressure differential is created between the first notch means and second notch means to cause a portion of the smoke to flow generally diagonally through the filter element from the region of one notch means toward the other notch means.
Claim 3
Dependent Claim
28 words
Tobacco smoke filter element of claim 1, wherein each of said notch means is defined by a generally semicylindrical wall formed in the surface of said filter body.
Claim 4
Dependent Claim
30 words
Tobacco smoke filter element of claim 1, wherein each of said notch means is defined by a series of ridges aligned axially with the longitudinal axis of the filter body.
Claim 5
Dependent Claim
25 words
Tobacco smoke filter element of claim 1, wherein said notch means are angularly disposed in said filter body with respect to the longitudinal axis thereof.
Claim 6
Dependent Claim
25 words
Tobacco smoke filter element of claim 4, wherein the innermost surfaces of the first and second notch means are disposed substantially parallel to each other.
Claim 7
Dependent Claim
52 words
Tobacco smoke filter element of claim 5, wherein the notch means, respectively, extend more than halfway through the filter body at each end thereof and extend progressively a lesser distance into the filter body until each terminates at the surface of the body at points adjacent the center portion of the body.
Claim 8
Dependent Claim
28 words
Tobacco smoke filter of claim 1, wherein said end walls lie in generally parallel planes which are inclined with respect to the longitudinal axis of said filter body.
Claim 9
Dependent Claim
23 words
Tobacco smoke filter element of claim 1, wherein one of said notch means terminates short of an end wall of said filter element.
Claim 10
Dependent Claim
76 words
Tobacco smoke filter element of claim 1, wherein secondary notch means are defined by said filter body, said secondary notch means being equal in length to less than one-half the length of the filter element and each extends from the same end wall of the filter element, said secondary notch means being arranged one on either side of one of said notch means and spaced around the periphery of the filter element from said notch means.
