Patent ID: 8632889

Claim:
A molded form-stabilized member having a) at least one first component comprising a pigmentation, b) at least one second component comprising a different pigmentation than the first component, and c) an interface representing a surface curved in space, formed by arrangement of the at least one second component within the at least one first component, wherein the interface ( 16 ) is essentially described by a family of parabolas, whereby the second component ( 14 ) has an essentially parabolic border line ( 42 , 44 , 46 ) towards the first component in a cross-sectional plane ( 36 , 38 , 40 ), wherein continuously decreasing maximums ( 48 ) go through at least 50% of the second component ( 14 ) in a taper direction ( 52 ), wherein the second component ( 14 ) respectively has an essentially parabolic border line ( 42 , 44 , 46 ) in all mutually parallel cross-sectional planes ( 36 , 38 , 40 ), and wherein the essentially parabolic border lines ( 42 , 44 , 46 ) have continuously decreasing maximums ( 48 ), starting from a major cross-sectional phase ( 22 ) in the taper direction ( 52 ) and extending perpendicular to the major cross-sectional plane ( 22 ).
